Description

[Detailed description of the invention] The present invention relates to an in-pipe coating device.

Plumbing work for laying water pipes, sewage pipes, seawater pipes, etc., was done by welding single pipes that had their insides painted at the factory beforehand and welded them together on site. After welding, when applying anti-corrosion coating to the inner surface of the joint of welded pipes and the surrounding area, residual welding slag, welding etc. had to be cleaned and removed. However, the caliber is 125
In the case of tubes with a diameter of less than mm, it is difficult for humans to enter the tube and perform cleaning and removal work, so the above-mentioned anti-corrosion coating is not possible.

Therefore, in order to apply anti-corrosion coating to the inner surface of a small diameter pipe, a coating apparatus disclosed in Japanese Utility Model Application No. 52-166866 has been provided as a conventional coating apparatus. This coating apparatus is shown in FIGS. 1 and 2. FIG. 1 shows the case where this coating apparatus is used for polishing and dust collection work, and FIG. 2 shows the case where this coating apparatus is used for painting work.

In FIG. 1, (201) is the main body. Main body (20
An air motor (20■) is housed inside the main body (201), and a wire brush (203) is detachably attached to the tip of the air motor (202).Six support arms are installed around the main body (201). (204') is detachably attached, and a roller (205) is provided at the tip of the support arm (204).Main body (201) ＼ L dispute Sodeyama 1- ・--t
An introduction pipe (207) can be connected to the rear end of the J dust machine (206). In addition, in order to introduce the main body (201) into the pipe, the introduction pipe (207) can be added.

Figure 2 shows several painted pulleys (208) installed at the tip of the body (201) instead of the wire brush (203) shown in Figure 1, and the body (201) replaced the dust collector (206).
) with a coating machine (209) connected to the rear end. In FIG. 2, the same reference numerals as in FIG. 1 indicate the same components as in FIG.

The conventional coating equipment described above performs the work in the following order.

■First, perform polishing and dust collection work.

The polishing work is performed by inserting the conventional coating device shown in FIG. 1 into the pipe and rotating the wire brush (203), and the dust collection work is performed by operating the dust collector (206). When performing polishing or dust collection work, if the pipe into which the conventional painting equipment is inserted is long, use the introduction pipe (207
).

■Next, do the painting work.

Painting work is done after polishing and dust collection work. For painting work, the conventional painting equipment shown in Figure 2 is inserted into the pipe, and a painting machine (2
This is done by spraying the paint sent from the paint pulley (208) from the paint pulley (208). In addition, when performing painting work,
As with the polishing and dust collection operations described above, when the pipe into which the conventional coating device is inserted is long, an introduction pipe (207) is added.

However, when detecting the coating position inside the pipe, conventional coating apparatuses have the disadvantage that the detection accuracy of the coating position is poor because the determination is made based on the distance that the introduction pipe is inserted into the pipe. In addition, conventional coating equipment requires adding an inlet pipe when the tube is long, so the longer the inlet pipe becomes, the more it bends, and the distance that the inlet pipe can be inserted into the pipe is severely restricted, resulting in disadvantages such as the inability to paint long tubes. had.

The present invention eliminates the above-mentioned drawbacks of the conventional methods, enables accurate detection of the coating device on the inner surface of a tube, enables painting of the inside of a long tube, and also enables rapid painting while being remotely controlled from outside the tube. The purpose of this invention is to provide a pipe inner surface coating device that can coat the inside of a pipe.

That is, the present invention provides a trackless guideway that is stretched between a guide pulley and a drive pulley of a self-propelled vehicle via a guide roller, and transmits the motion of a drive motor attached to the self-propelled vehicle to the trackless guideway. In a tube inner surface coating device that enables a self-propelled vehicle to travel freely, the self-propelled vehicle includes an automatic scrubber or a paint machine attached to the tip of the self-propelled vehicle, and an automatic cleaner or paint machine attached to the self-propelled vehicle to detect the traveling position of the self-propelled vehicle. This pipe painting device is equipped with a radio isotope installed, an in-tube television camera mounted on the self-propelled vehicle to see the situation inside the pipe, and a cleaning device mounted on the rear end of the self-propelled vehicle.

Embodiments of the present invention will be described below based on the drawings.

3 to 19 show embodiments of the present invention, (1
) is a self-propelled vehicle. The self-propelled vehicle (1) is an automatic sander (110
), a cleaning air hose (57), a cleaning air hose (77), a conductive cable (56), a cleaning air hose (57), which carries the in-tube television camera (7) to a long-distance cleaning position, and supplies air and electricity as a power source. Towing wires (82) and control cables (10). An electric motor (18) serving as a self-propelling source is attached to the rear of the self-propelled vehicle board (40). The electric motor (18) is connected to a generator (
Electricity is supplied from 76) via a conductive cable (56), a support for connector protection and weight adjustment (35), and an IJ cable (67).

The rotational motion generated from the electric motor (18) is transmitted through the transmission mechanism (
19), and the driving pulley (2) attached to the end of the shirt (41) with a joint fixing screw (26).
5), and in the long axis direction - with respect to the self-propelled vehicle base rod (40).
It is often converted into rotational motion.

The rotational movement is caused by a shaft (4) at the front end of the self-propelled vehicle base plate (40).
It was integrally fixed to the guide pulley (27) and drive boob IJ-(25) attached in step 2), and to the self-propelled vehicle board (40) using three supports (61). Consists of a rubber belt or the like fitted between the six rotating wheels of a freely rotating guide roller (28) that determines the rotation direction and height of the self-propelled vehicle body by a saddle (29) and a falling-off prevention pin (60). When the electric motor (18) rotates the electric motor (18), the self-propelled vehicle (1) moves between the pipe body (P) and the trackless belt (24).
) will move forward and backward in the pipe due to the frictional resistance at the contact surface. . Forward and reverse movement control is easily and reliably carried out via the conductive cable (56) by remote control of the start button and speed adjustment slide knob on the control panel (66) installed outside the pipe. .

Others (Lower 2) and (Lower 3) are for damage prevention during transportation of the self-propelled vehicle (1) fixed to the self-propelled vehicle with screws, lower storage skid rod and upper protective skid rod, (Lower 9) are The fixing plate for the upper protection skid, (34) is a fixing plate screw, and (61) is a support for the lower protection skid rod, which also serves to fix the saddle (29).

In addition, in the unlikely event that the self-propelled vehicle (1) overturns inside the pipe (P), the flat ends of both the upper protection skid rod (66) and the lower storage skid rod (62) are bent inward. The outer ends of the drive pulley (25) and guide pulley (27) are also machined into a conical shape to make it easy to slide. It will be possible to pull it out of the tube.

If we were to list further features of the self-propelled vehicle, as can be inferred from Figure 6, the self-propelled vehicle board (40), which accounts for most of the weight of the self-propelled vehicle (1), is placed at the bottom of the self-propelled vehicle. As a result, a low center of gravity mechanism is maintained even after insertion into the tube. When the self-propelled vehicle (1) moves straight inside the tube (P), the guide roller ridges (32-'-32-3) which are integrally fixed with the inner surface of the tube (P) are used.
, 32-2 to 32-4) and the elongated trackless body (24), and when the self-propelled vehicle runs on a curved pipe, the contact surface with the inner surface of the curved pipe moves forward. If the direction is counterclockwise, most of the weight of the self-propelled vehicle will be applied near both ends of the guide rollers 32-2 and 32-3.

Due to the interaction between this phenomenon and the above-mentioned self-propelled vehicle having a low center of gravity with respect to the tube center line, the tip guide roller (62
- When the self-propelled vehicle (1) moves forward near the pipe, it will move forward while sliding down the pipe moderately without climbing up the inner wall of the pipe too much, so if it is a curved pipe that the self-propelled vehicle (1) can pass through, it will overturn. Its feature is that it can run smoothly without any friction.

Additional features include increasing the traction power of self-propelled vehicles and making it possible to handle cases where long-distance travel is required. The electric motor (18) and transmission mechanism (19), which are integrated with the joining screw (74), are fixed to the self-propelled vehicle board (40) with the board screw (22), so the board screw (74)
22), it can be easily attached and detached. Such a mechanism is also applied to the front of a self-propelled vehicle.

Since the mounting of the self-propelled vehicle board (40) and the transmission mechanism (19) case is fixed by an interlocking type board screw (22) joint, this mechanism can also be adopted at the front of the self-propelled vehicle, as shown in Fig. 7. And as shown in Fig. 8, if you remove the grinder and paint machine from the front and install the same electric motors (18, transmitters 1., (19')) as those installed at the rear, the induction system will be installed. Pulley (27
) can be converted to a drive pulley (27) and run.In other words, if it becomes a four-wheel drive pulley, the traction force will further increase and long distance travel will be possible.

A method of connecting the cleaning machine and the painting machine when the four-wheel drive pulley one-way type is adopted will be described later.

Among other members responsible for the functions of the self-propelled vehicle body, there is an adjustment screw (20). The screw (2o) is used to adjust the tension of the trackless belt, replace the trackless belt, and attach/detach the electric motor/transmission mechanism. Further, (66) is the front/rear self-propelled vehicle board/(40) fastening screw.

The essential components for cleaning and painting are described below.

(2) is a low-level radio isotope that is always emitted at the location while the self-propelled vehicle is running within the pipe, and the height can be adjusted using a support metal fitting (ro) and a metal support key (4) at the front of the self-propelled car. The detection device is attached to the self-propelled vehicle board (40) by a fixed board (5) and fixed support screws (6), which can adjust the height of the radio isotope (2) depending on the thickness of the bottom plate. ) is firmly fixed.

Detection equipment including radioisotope (2) is shown in Figure 9~
As shown in FIG. 11, it consists of four types of elements. That is, a radio isotope (2), a detector (61) containing a 0M tube, an indicator (66) installed at the tube end workplace, and a joint cable (62) for transmitting electrical signals.

and connect to the display. As the radio isotope (2) attached to the self-propelled vehicle approaches the previously placed tube body (Pme L), the 0M tube in the detector begins to operate and the signal lamp (64) lights up. Flashing. When the process progresses further and the marker (90) matches the radioisotope (2),
At the highest sensitivity, the signal lamp (64) blinks continuously and changes from blinking to extinguishing as you get farther away. These series of conditions are detected only at one point without the self-propelled vehicle traveling continuously within the area.

The signal detected by the detector is transmitted via the joint cable to the indicator (63) and signal lamp (92) installed at the pipe end work area to facilitate hand-held operation of the self-propelled vehicle. The signal lamps are turned on in synchronization. (65) is a bell indicator that displays the sensitivity of the detection signal, (94) is a detector sensitivity adjustment section, and (95) is a display sensitivity adjustment knob.

The self-propelled vehicle can also be equipped with an in-service television camera (7), and the television holding jig (8) is screwed onto the fixed base (5) and the self-propelled vehicle board (40) using six jig fixing screws. , and is tightened with a camera adjustment screw (9).As shown in the figure, this screw (9) is used to adjust the vertical angle of the television camera, and to adjust the angle of the television camera in the vertical direction, as well as the long hole of the television holding jig (8). Fine adjustment of the direction is also possible. Electricity supply and control is performed via a control cable (10) with a generator (76) installed outside the pipe and a TV monitor control knob (67'). The situation is displayed on a television monitor (67) and monitored.

Next, the automatic sanding machine (1) mounted on the self-propelled vehicle (1) in Figure 6
10) The relationship will be explained in conjunction with FIG. 17.

(16) inserts its rear part into the support tube (15) using a cleaning air motor and is fixed with a fixing screw (16). Further, the support tube (15) is fitted into a circular hole in the fixed base (5) and tightened with a radioisotope height adjustment/support screw (68) to facilitate attachment and detachment.

A retaining disc (11) for piano wire (12) is firmly attached to the tip of the air motor center shaft (17) with a nut (14), and once it is connected to the air control box (70) via the abrasive air hose (57). When air is supplied, the air motor rotates and at the same time the holding disc (11) also rotates at high speed.

Due to the high speed rotation, the twisted piano #it (12) has been damaged by the welding slag remaining on the inner wall of the pipe, the welding heat burnt paint film, rust, etc. It applies a strong impact force to harmful substances and abrades them.

When the air control box is closed and the air supply is stopped, the cleaning work on the piano wire (12) will also be completed, and the piano wire (12) will be free to pick up, so the self-propelled vehicle can There is no risk of damaging existing coatings during running.

Furthermore, a cleaning device (87), which is necessary as a step of the cleaning work, is attached to the self-propelled vehicle board at the bottom of the rear end of the self-propelled vehicle with a cleaning device ft screw (43).
It is installed with. From the above, via/@(12) i11
In order to discharge the welding slag, burnt paint film, rust, etc. that have fallen near the lower part of the impact force C pipe body (P) out of the pipe, connect the cleaning air hose (77) from the air control box (70) with red and white. The compressed air is sent to the air inlet (96) of cleaning device #j (87) in FIG. 12 and purged from the air blower (97).

The purge direction is opposite to the traveling direction of the self-propelled vehicle, that is, toward the end of the self-propelled vehicle insertion tube. Air pressure is not controlled by pulp etc.
Since it is directly connected to the compressor (68), it is ensured that only the hose pressure loss is required for cleaning.

Next, the coating machine (ill) will be explained based on FIGS. 14 to 17.

As mentioned above, the coating machine main shaft (49) is supported during the cleaning work @'
(15) is fixed in the same circular hole as the fixed base (5) into which the body shaft was fitted, and a gear box (48) and a painting air motor (46) are connected to the front part of the body shaft.

Compressed air is sent from the air control box (7 [)) installed in 'tIMl'L to the air motor hose (4)) via the painted air hose (55), which instantly rotates and decelerates the gear box. A rotation speed corresponding to the ratio is transmitted to the fixed nozzle tube (50), and the tip (55), nozzle (54), and extension nozzle (52) that spray paint toward the inner wall of the tube also rotate inside the tube.

A hopper (76) is filled into the lower part of the shaft of the main body of the coating machine, and after pressurizing with an airless spray pump (75), the paint that has been pumped through the i-material hose (5B) is introduced, and the paint 1f is filled.

The supply and stop of paint is performed by opening and closing a needle (91) built into the shaft (49) of the main body of the paint sprayer, and the power source is an air-operated air cylinder (9 filters) fed from an air cylinder air hose (55 air hoses). There is a
17) As with the position, adjust the plate thickness of the fixed base (5) and the liner (98) so that it is on the center line in the pipe radial direction.

In addition, in order to accommodate changes in pipe diameter, it is possible to always select the desired coating surface path distance and pattern width (5)
1) is provided.

FIG. 18 shows a method of attaching a T-shaped extension nozzle (59) and coating tips (60, 60') designed especially for internal coating. An internal surface coating machine is usually equipped with - number of nozzle tips, and paints the inner surface by the rotational movement of the tips while spraying the paint from the tips in a fan shape as described above. There was a risk that the paint would not form the correct pattern or sometimes not be sprayed due to "smearing" caused by foreign matter such as minute pieces of cured paint contained in the pressure-fed paint.

In order to solve this concern, we adopted a T-type extension nozzle (59) attached to the front part of the nozzle fixed tube (5o) with a mounting hole (51"), and two pieces facing each other were installed at the tip of the nozzle. Paint chips (60, 60') were installed.

However, the angle of the nozzle tip is slightly shifted in the opposite direction from the center axis of the tube so that the paint sprayed from the tip does not interfere with each other. As a result of adopting this nozzle, the paint
Not only has the amount of "stain" been reduced by half, but the amount of spray has increased and time has been saved when painting the entire surface of long-distance pipes.

The mechanism of each device necessary for painting the inner surface over a long distance has been described in detail based on examples, and the working process when using the device will be described below.

As shown in Fig. 18, the self-propelled vehicle equipped with the equipment related to the grinder is mounted on the launcher (R), and the rib (84), which is welded to the launcher, is attached to the pipe of the pipe body (P). Hook it on the end (85) and bring the tube end (85) and launcher (R) into close contact.

The auxiliary wire (82) from the wire reel (81) is attached to the hook (23) of the self-propelled vehicle, and the conductive cape for self-propelled vehicle (56) is connected to the generator (73), the cable (79) and the self-propelled vehicle. The control cable (10) of the in-service television camera is connected to the self-propelled vehicle via the vehicle control panel (66) and the self-propelled vehicle drum (78).
From the TV monitor (67) to the self-propelled vehicle via the TV drum (80), the +II scavenging air hose (57) is connected to the compressor (68), the -second air hose (69), the drain (71), and the air control box (70). ), the cleaning air port (7
7) are respectively attached to the self-propelled vehicle through the same route as the abrasive air hose (57).

On the other hand, if the part to be polished is limited to the welded part (B), then the detector (61) is The joint cable (62) is connected to the display device (66) installed in the out-of-control work area.
) Press the start button and the self-propelled vehicle will start driving. As you approach the first weld (B) from the tube end, the tube body (P)
The M tube in the detector (61) placed above the radioisotope (2) begins to react, and when the radioisotope and the marker match, the signal lamp (64) lights up continuously. Therefore, the self-propelled vehicle will be stopped at this point. The situation can be seen on the display (
66) can be grasped at the same time, and furthermore, the transition state from blinking to continuous lighting is devised so that it can be determined not only by the display signal lamp (92) but also by the quality of the level indicator (65). .

Next, compressed air is sent from the air control box (70) to the grinding air motor (16), and when the air motor is rotated, the holding disc (11) attached to the tip rotates and the piano wire is tightened. (12) removes welding slag burnt paint film, rust, etc.

The subsequent cleaning work was performed on the single welded part (B) of the welded part (B).
B'), so the detector is (PB'-L)'tk
On the body: Carry out the same work as above, such as restoring the vehicle, stopping the self-propelled vehicle, and cleaning the piano wire. This series of cleaning operations is repeated sequentially from the tube end weld (B) to the farthest weld (B9). When the cleaning up to the fastest welding part (B8) is completed, move from the welding part to the pipe end (85), move the self-propelled vehicle continuously backwards, and at the same time, start the air blower (9) of the cleaning device (87).
7) Continuous blowing is carried out, and while each hose is wound around a drum, welding slag, burnt paint film, rust, etc. that have already fallen to the bottom of the pipe are discharged out of the pipe at once.

After finishing the cleaning work inside the pipe, the self-propelled vehicle returns to the launcher (R). At this time, the support tube (15) of the cleaning air motor (13) is removed from the fixed base (5), and the cleaning related cleaning and cleaning air hoses (57, 77) are also removed from the self-propelled vehicle. Attach the equipment. However, other equipment used for cleaning and painting, such as the auxiliary wire (82), the conductive cable (56), and the control cable for the in-tub television camera (10) will remain in place.

Since the starting point for the painting work is the furthest welded part (BF') of the tube body, the self-propelled vehicle is stopped after traveling to the welded part.

The paint hose (58) is an airless spray pump (75)
A single painting air hose ( The cylinder air hoses (55) are sent from each cylinder air hose (55) in the self-propelled vehicle section, and are used by branching into the air motor hose (47), so they are tightly screwed together.Before painting, the airless spray pump (75) Once the paint hose (58) is in operation and the paint hose (58) is filled with pressurized paint, tip rotation and paint spraying are performed simultaneously by opening the lever of the air control box (70), and the welded part (B'') The inner surface painting is completed within an instant.

The painting work starts from the farthest welded part (B8) to the pipe end welded part (
Paint the inner surface of all welded parts repeatedly in direction B) for each welded part.

Up to that point, we have described in detail a standard example using a self-propelled vehicle equipped with a One motor, but an example that enables even longer distance painting is shown in Figures 7 and 8. Induction boo!
J-(27) is equipped with electric motors (18 pieces) and transmission mechanisms (19') similar to those at the rear end, and the induction pulley (27
) was converted into a 4-wheel-drive towing vehicle (1') system with 27 drive pulleys.The mechanisms related to other sweepers and paint machines using this system are shown in Figures 18 to 19. Become.

The towing vehicle (11), that is, the above-mentioned self-propelled vehicle, and the cleaning machine/painting engine are completely separated mechanisms, and the tip of the cleaning machine-related part from the cleaning air motor support tube (15) mounted on the self-propelled vehicle is completely separated. ,
Radio isotope (2) related, in-service television camera (7)
) relationship, and the fixed base (5) relationship set is the traveling roller (
103), a traveling trolley (103) consisting of the frame (102)
88). (99) is a fixed base with a sliding plate (5)
It is fixed by a butterfly screw (100) of a sliding groove plate (104) which is welded to the screw (101) of the frame (102).

If the pipe diameter changes and it becomes necessary to move the air motor center shaft (17) onto the center line of the pipe diameter, loosen the butterfly screw and slide it to adjust it to the center line.

The towing vehicle (1') and the grinding device are connected by connecting a trolley connecting rod (105) protruding from the rear of the traveling vehicle to a towing connecting rod (107) on the towing vehicle side via a universal joint (112). , the towing vehicle pushes the traveling trolley, that is, the grinder.

Similar to the sanding machine, the painting equipment is mounted on a traveling trolley (88) and driven by a towing vehicle within the jurisdiction. Other than that, the process and procedure are as described above.

In addition, position detection devices using radio isotopes are only available for long vibration lines using attached pipes, water pipe bridges, shielded pipes, and light optics where the detector can directly contact the pipe body during piping work or even after piping is completed. However, it is not suitable for propulsion pipes or buried pipes, so under these conditions the in-pipe television camera is used to position welds, etc.

However, under conditions where a radio isotope device can be used, an embodiment that makes it possible to paint over longer distances is equipped with an in-service television camera (
7), when the control cable (10) was removed.

With this equipment, we were able to significantly extend the mileage and improve the efficiency of painting work.

As described above, the present invention stretches a trackless belt between the guide pulley and the drive pulley of a self-propelled vehicle via a guide roller,
By transmitting the motion of the drive motor attached to the self-propelled vehicle to the non-moving belt, the self-propelled vehicle can move freely.
It is possible to paint inside long tubes, and since it is equipped with a radioisotope, it has the effect of accurately detecting the painting position. Further, since the present invention is equipped with a television camera, it is possible to accurately see the inside of the pipe, and since the present invention is equipped with a cleaning device, cleaning work can be carried out. Furthermore, since the present invention is equipped with an automatic cleaning machine or a painting machine, it has the effect that cleaning work and painting work can be carried out within the pipe.
