Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erection and gathering and conveying apparatus suitable for conveying raw wood, beam materials and the like through wire rope in the air.

[0002]

2. Description of the Related Art This type of erection and collection transportation device is supervised by the Safety Division of the Ministry of Labor, Health and Safety Department, and published by the Forestry Workers' Accident Prevention Association on September 10, 1986. Those described in "Must Have" are well known.

Of these prior arts, the same as the above book No. 23.
Special carriages with an unloading rope winder for double endless rope erection rigs, as described on page 24, are also known.

[0004]

The above-mentioned prior art is to wind the unloading rope by the carriage, and as a means therefor, a drive pulley installed on the carriage by an endless exclusive wire rope laid between the original pillar and the leading pillar. Since the hoisting rope hoisting body is rotated forward and backward via the gears and the gear set, hoisting and unloading of the hoisting rope is performed. There is a problem that the rope between the main pillar and the carrier is talted by its own weight when lowering the hanging tool, and the hanging tool does not come down.

Further, in the above-mentioned prior art, since the carrier cannot be clamped to the main ropes, there are many problems that the carrier may be deviated at the time of loading and unloading on a sloping ground, which is also dangerous. There was

According to the present invention, in order to eliminate the above-mentioned problems, the hoisting and lowering rope for unloading and loading is also used as the pulling rope of the carrier, and the rope for driving the winding drum of the hoisting rope is used for the carrier. By using it as a pull-back line, it aims to simplify the work of rigging and to prevent the carry-out device from moving by allowing it to be clamped to the main rope when unloading and unloading.

[0007]

DISCLOSURE OF THE INVENTION The above-mentioned object of the present invention is to provide a collecting material conveying device in which a carrier is hung and suspended by front and rear pulleys on a main rope stretched between a main column and a front column. An elevating body having a clamper facing the lower surface of the main rope receiving plate fixed to the upper part of the side plate and a braking body in the lower part is arranged so as to be able to ascend and descend with respect to the side plate and to be able to self descend by the elastic force of the spring, and this ascending and descending. A pair of left and right constant pulleys are pivotally supported on the side plates in the upper part of the moving pulley pivotally supported at substantially the center of the body, and two winding drums coaxially integrated with the braking disc on which the braking body is slidably contacted are provided at the lower portions of the side plates. A braking line wound around a first winch of the three winches fixedly provided adjacent to the main column is connected to the upper part of the front column via the fixed pulley and the moving pulley, and the second winch is also provided. Middle part of the pulling rope for both lifting and lowering, which is wrapped around the winch The first winding drum of the carrier is wound around and the hanging tool is attached to the lower end thereof, and the pullback rope wound around the second winding drum is returned to the original pillar side by the fixed pulleys above and below the leading pillar. It can be achieved by winding it around a third winch.

[0008]

[Operation] When the carrier existing on the side of the original pillar is moved to the position just above the logging site through the pullback rope by the rotational force of the third winch, first, when the first winch is loosened, the spring force of the carrier is elastic. Then, the lifting body 5e descends to release the main rope clamp, and at the same time, the braking body is pressed against the braking disc to brake the first and second winding drums.

Then, when the retracting rope is started to be wound around the third winch while applying a slight braking to the second winch, the second winding cylinder in the pre-braking state is the retracting rope and the direction of the front pillar is reached. Since it is pulled by the truck, the transporter can be moved along the main rope to just above the logging site.

When the braking rope is strongly wound around the first winch, the traction force causes the elevating body to move upward together with the clamper and the braking body against the elastic force of the spring through the moving pulley to receive the main rope. The main ropes can be clamped by tightly sandwiching the plate and the clamper, that is, the carrier itself can be made immobile, and at the same time, the braking body is separated from the braking disc to release the braking and each winding cylinder can be rotated.

After that, when the pull-back rope is wound around the third winch while applying a slight amount of braking to the second winch, each winding cylinder is in a rotation-free state. The winding cylinder rotates in the direction in which the suspending tool is lowered, and the loader can put the log into the suspending tool that has come down and put it in a standby state of suspending it through the sling rope.

[0012] Next, when a lifting and lowering pulling rope is wound around the second winch while applying some braking to the third winch, the lower part of this rope is lifted together with the suspending tool and the log to bring the log to a predetermined height. Can be raised.

Next, when the first winch is loosened, the elastic force of the spring can release the clamped state of the main rope, and at the same time, the braking body is pressed tightly against the braking disc to brake each winding cylinder, and then the second winch is released. By winding up and down the pulling rope around the winch, it is possible to pull the carrying rope along the main rope in the direction of the original pillar while pulling out the pulling rope from the third winch which is slightly braked, and pulling it together with the log.

After the pulling is completed, the braking line is tightly wound around the first winch to make the main drum clamp state in the winding drum free state, and then the pulling back line is moved to the third winch while applying some braking to the second winch. By winding it around the winch, you can lower the log together with the hanging tool to the vicinity of the main pillar, just like when pulling down the hanging tool, and remove the hanging tool from the sling rope on the ground or on the truck to collect the timber. ..
