Description

Mining deceleration type explosion-proof all-in-one machine

Technical Field

The present invention relates generally to the field of all-in-one machine technology. More specifically, the invention relates to a deceleration type explosion-proof all-in-one machine for a mine.

Background

The scraper conveyor structurally comprises a driving device and a conveying device, wherein the driving device comprises a motor mechanism and a speed reducing mechanism, and the conveying device comprises a chain wheel, a chain and a chute. The output end of the motor mechanism is in transmission connection with the input end of the speed reducing mechanism, and the power generated by the motor mechanism is input into the speed reducing mechanism; sprocket is connected in reduction gears's output transmission for power that will receive from motor mechanism slows down and transmits the sprocket in to the conveyer and rotates with driving sprocket, drives the chute motion when the sprocket rotates, transports the assigned position with the dust of collecting in the ash bin.

The driving device of the scraper machine comprises a machine head driving device arranged at a machine head of the scraper machine and a machine tail driving device arranged at a machine tail of the scraper machine, and the structures of the scraper machine head and the machine tail are different, so that the scraper machine head and the machine tail are matched, the structures of speed reducing mechanisms in the machine head driving device and the machine tail driving device are different, namely the speed reducing mechanisms in the scraper machine head driving device and the machine tail driving device in the prior art can not be used universally, and one speed reducing mechanism can only be used in the machine head driving device or can only be used in the machine tail driving device. In addition, if the capacity of the scraper chute is large or the transport distance is long, the power required to be provided by the driving device is also large, i.e. the motor mechanism is required to output large power. When the output power of the motor mechanism becomes large, the volume of the motor mechanism also becomes large correspondingly. Since the input axis of the speed reduction mechanism is fixed, when the volume of the motor mechanism connected thereto becomes large, interference with other devices located at the bottom of the drive device occurs. Therefore, in the prior art, the conveying capacity of the scraper conveyor is difficult to be improved by means of improving the driving force of the motor.

From the above, it can be seen that the conventional scraper driving device cannot simultaneously achieve the problems of versatility and output power.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it should be understood by those skilled in the art that the embodiments described below are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 shows a deceleration type explosion-proof all-in-one machine for mining, which includes a deceleration mechanism 1, a motor mechanism 2 and a frequency conversion mechanism 3, wherein the motor mechanism 2 includes a motor housing, and a motor structure for providing power is arranged in the motor housing; the frequency conversion mechanism 3 comprises a frequency conversion shell, and a frequency converter is arranged in the frequency conversion shell.

As shown in fig. 2 and 3, the reduction mechanism 1 includes a reduction casing 11, an input connecting shaft 12 and an output connecting shaft 13 are provided on the reduction casing 11, and a reduction structure is provided in the reduction casing 11. The input connecting shaft 12 is in transmission connection with the motor mechanism 2 and is used for acquiring power from the motor mechanism 2; the speed reducing structure is in transmission connection with the input connecting shaft 12 and the output connecting shaft 13 and is used for carrying out rotating speed reduction processing on the power acquired by the input connecting shaft 12 and transmitting the power to the output connecting shaft 13; the output connecting shaft 13 is used for being in transmission connection with the scraper conveyor and outputting the power with the reduced rotating speed to the scraper conveyor to drive the scraper conveyor to run. The axes of the input connecting shaft 12 and the output connecting shaft 13 are parallel and parallel. For convenience of description of the structure of the reduction mechanism, the direction in which the axes of the input connecting shaft 12 and the output connecting shaft 13 extend is referred to as the width direction of the reduction housing 11, the direction in which the input connecting shaft 12 and the output connecting shaft 13 are arranged in parallel is referred to as the length direction of the reduction housing 11, and the direction perpendicular to the width direction and the length direction of the reduction housing 11 is referred to as the height direction.

In the mining deceleration type explosion-proof all-in-one machine shown in fig. 1, the motor mechanism 2 and the frequency conversion mechanism 3 are arranged in parallel on the first side surface 111 of the deceleration mechanism 1, and are distributed in parallel on the first side surface 111 along the length direction of the deceleration mechanism 1, so that the structure of the all-in-one machine is uniform, and the center of gravity is located at the position of the geometric center of gravity. On one hand, the arrangement mode is convenient for determining the gravity center of the all-in-one machine, and the all-in-one machine can be stably maintained without swinging when being hoisted; on the other hand, the gravity center of the integrated machine is stable and the bottom of the integrated machine is stressed uniformly during transportation or storage, so that the integrated machine can be prevented from deforming.

In the reduction mechanism 1 shown in fig. 2 and 3, the input connecting shaft 12 includes the first cylinder 120, the output connecting shaft 13 includes the second cylinder 130, the first cylinder 120 and the second cylinder 130 are both mounted on the reduction casing 11, and the length direction is the width direction of the reduction casing 11. The first cylinder 120 is rotatable about the axis of the input connecting shaft 12, and the second cylinder 130 is rotatable about the axis of the output connecting shaft 13. The two ends of the first cylinder 120 and the second cylinder 130 are both provided with openings, the first cylinder 120 is provided with a first connecting structure 121 for driving and connecting with a motor mechanism, and the second cylinder 130 is provided with a second connecting structure 131 for driving and connecting with a scraper. The speed reducing structure is in transmission connection with the first cylinder 120 and the second cylinder 130, is used for reducing the rotating speed of the power acquired by the first cylinder 120 from the motor mechanism, and transmits the power to the second cylinder 130, and drives the scraper conveyor to operate through the second cylinder 130. When the motor mechanism 2 is assembled on the first side 111 of the speed reducing housing 11, the output shaft thereof can be in transmission connection with the first connecting structure 121 through the opening of the first cylinder 120 at the first side 111, and the input shaft of the scraper machine can be in transmission connection with the second connecting structure 131 through the opening of the second cylinder 130 near the second side 112 of the speed reducing housing 11, and the driving device can be used as a nose driving device of the scraper machine; when the motor mechanism 2 is mounted on the second side 112 of the reduction casing 11, its output shaft can be in transmission connection with the first connecting structure 121 through the opening of the first cylinder 120 at the second side 112, and the input shaft of the scraper can be in transmission connection with the second connecting structure 131 through the opening of the second cylinder 130 at the first side 111, and the driving device can be used as a tail driving device of the scraper.

In the reduction gear mechanism 1 shown in fig. 2 and 3, the height of the axis of the input connecting shaft 12 is greater than the height of the axis of the output connecting shaft 13, so that the distance between the axis of the motor mechanism 2 and the bottom device thereof is increased, and when the output power of the motor mechanism 2 is increased, the motor mechanism 2 does not interfere with other devices at the bottom due to the overlarge volume.

In summary, the integrated machine provided by the present application, on one hand, when the motor mechanism 2 is mounted on the first side 111 of the speed reduction housing 11 in the width direction, can be used as a nose driving device of a scraper; when the motor mechanism 2 is assembled on the second side surface 112 in the width direction of the speed reducer casing 11, the all-in-one machine can be used as a tail driving device of the scraper conveyor, namely, the all-in-one machine can be used as a head driving device and a tail driving device, so that the all-in-one machine has the advantage of strong universality. On the other hand, the height of the axis of the input connecting shaft 12 is larger, so that the height of the axis of the motor mechanism 2 is larger, and therefore, when the motor mechanism 2 with larger output power is adopted in the integrated machine, the phenomenon that the motor mechanism 1 cannot be assembled on the scraper conveyor due to overlarge volume cannot occur. In summary, the all-in-one machine provided by the application can simultaneously take account of both universality and output power.

In one application scenario, the first connecting structure 121 is a first connecting key disposed on an inner wall of the first barrel 120, such as an internal spline disposed on an inner wall of the first barrel 120, and is connected with the output shaft of the motor mechanism 2 through the internal spline. The second connecting structure 131 is a second connecting key disposed on the inner wall of the second cylinder 130, such as an internal spline disposed on the inner wall of the second cylinder 130, and is keyed to the input shaft of the scraper. The speed reducing mechanism 1 with the arrangement mode can be connected with the motor mechanism 2 and the scraper conveyor in an inserting mode, and convenience in assembly of the speed reducer can be improved.

The deceleration structure in the deceleration casing 11 will be described in detail below by taking a specific implementation as an example.

As shown in fig. 4, the speed reducing structure includes an intermediate connecting shaft 140, a first gear 141, a second gear 142, a third gear 143, and a fourth gear 144, wherein the axial length direction of the intermediate connecting shaft 140 is the width direction of the speed reducing housing 11, and the axial lines thereof are distributed in parallel with the axial line of the input connecting shaft 12 and the axial line of the output connecting shaft 13 in the length direction of the speed reducing housing 11. The first gear 141 and the input connecting shaft 12 are coaxially disposed and are in transmission connection, the second gear 142 and the first gear 141 are in meshing transmission connection through gear teeth, the third gear 143 and the second gear 142 are coaxially in transmission connection through the intermediate connecting shaft 140, and the fourth gear 144 and the third gear 143 are in meshing transmission connection through gear teeth and are coaxially disposed and are in transmission connection with the output connecting shaft 13. The diameter of the first gear 141 is smaller than that of the second gear 142, so that the rotation speed of the power is reduced when the power is transmitted from the first gear 141 to the second gear 142; the diameter of the third gear 143 is smaller than that of the second gear 142, and the diameter of the fourth gear 142 is larger than that of the third gear 143, so that the rotation speed of the power is reduced again when the power is transmitted from the third gear 143 to the fourth gear 144. In addition, the second gear 142 and the fourth gear 144 may be arranged in a staggered and overlapping manner in the width direction of the reduction housing 11 and arranged in parallel in the length direction of the reduction housing 11, so that the width of the reduction mechanism 1 (i.e., the axial length of the reduction mechanism 1) is reduced, and the reduction mechanism is convenient to assemble in a narrow space such as a mine.

The reduction mechanism 1 described above has the operating principle that: the input connecting shaft 12 takes power from the motor mechanism 2 and transmits the power to the first gear 141 through the transmission connection between the input connecting shaft 12 and the first gear 141; the first gear 141 transmits the power obtained from the input connecting shaft 12 to the second gear 142 through the transmission connection with the second gear 142, and reduces the rotation speed for the first time in the transmission process; the second gear 142 transmits the power it takes to the third gear 143 through the intermediate connecting shaft 140; the third gear 143 is connected to the fourth gear 144 through transmission, and transmits the power taken from the second gear 142 to the fourth gear 144, and the rotation speed is reduced again in the transmission process. The fourth gear 144 transmits the power obtained from the third gear 143 to the output connecting shaft 13, and drives the operation of the scraper by the output connecting shaft 13.

Further, in one application scenario, the first gear 141, the second gear 142, the third gear 143, and the fourth gear 144 are all herringbone gears, and are used to prevent the two gears meshing with each other from drifting in the axial direction. Taking the first gear 141 and the second gear 142 as an example, after the gear teeth of the first gear 141 and the second gear 142 are engaged, the gear teeth of the first gear 141 generate resistance force to prevent the second gear 142 from moving in the axial direction, so as to prevent the second gear 142 from drifting; the teeth of the second gear 142 also generate resistance against the movement of the first gear 141 in the axial direction, preventing it from drifting. Similarly, the third gear 143 and the fourth gear 144 are herringbone gears, which can prevent the drift from occurring.

The following description will discuss an implementation and an operation principle of the intermediate connecting shaft 140 by taking a specific application scenario as an example.

In an application scenario, the intermediate connecting shaft 140 is disposed through the speed reducer case 11, that is, two ends of the intermediate connecting shaft 140 are disposed on two lateral sides of the speed reducer case 11 along the width direction, respectively, to provide support for assembling the second gear 142 and the third gear 143 in the speed reducer case 11. In one implementation, as shown in fig. 5, the first side 111 of the reduction casing 11 is provided with a first mounting hole 113, and the second side 112 is provided with a second mounting hole 114. The first mounting hole 113 corresponds to the position of the second mounting hole 114, a first bearing 151 is disposed in the first mounting hole 113, a second bearing 152 is disposed in the second mounting hole 114, and the axial directions of the first bearing 151 and the second bearing 152 are both the width direction of the reduction gear housing 11. One end of the intermediate connection shaft 140 is fixedly fitted in the inner hole of the first bearing 151 and the other end is fixedly fitted in the inner hole of the second bearing 152, so that the intermediate connection shaft 140 can rotate along its own axis. The intermediate connecting shaft 140 not only can provide support for the assembly of the second gear 142 and the third gear 143 on the reduction casing 11, but also can transmit the power of the second gear 142 to the third gear 143, so as to realize the transmission connection between the second gear 142 and the third gear 143.

The above-mentioned implementation manner of the intermediate connection shaft 140 is exemplary and not restrictive, and in other application scenarios, the intermediate connection shaft 140 may adopt other implementation manners, such as fixedly mounting both ends of the intermediate connection shaft 140 in the first mounting hole 113 and the second mounting hole 114, respectively, and providing a driving sleeve on the intermediate connection shaft 140, so that the driving sleeve and the intermediate connection shaft 140 can be rotatably assembled (for example, the driving sleeve is assembled on an outer diameter of a bearing, the intermediate connection shaft 140 is assembled in an inner hole of the bearing, and both are rotatably assembled through the bearing), that is, the driving sleeve can rotate with an axis of the intermediate connection shaft 140 as a center line. The transmission sleeve is fixedly assembled in the inner holes of the second gear 142 and the third gear 143, and the second gear 142 and the third gear 143 are in transmission connection through the transmission sleeve. The intermediate connecting shaft 140 of this arrangement may provide support for the assembly of the second gear 142 and the third gear 143, and the driving sleeve may drivingly connect the second gear 142 and the third gear 143.

Further, in a further application scenario, the first gear 141 is a part of the first cylinder 120, that is, teeth distributed along a circumferential direction of the outer wall of the set position of the first cylinder 120 are provided on the outer wall, and the teeth and the set part on the first cylinder 120 form the first gear 141. This arrangement can reduce the diameter of the first gear 141 and increase the transmission ratio between the second gear 142 and the first gear 141, so as to improve the speed reduction effect when the first gear 141 transmits power to the second gear 142. The fourth gear 144 is assembled on the outer wall of the second cylinder 130, that is, corresponding connection structures are respectively arranged on the inner wall of the fourth gear 144 and the outer wall of the second cylinder 130 (for example, a flat key is arranged on the inner hole of the fourth gear 144 and a corresponding flat key groove is arranged on the outer wall of the second cylinder 130), the second cylinder is assembled on the inner wall of the fourth gear 144 through the connection structures, and in another implementation manner, the fourth gear 144 and the second cylinder 130 can also be integrally arranged to improve the reliability of connection.

In one application scenario, the reduction housing 11 is further provided with a mounting structure for supporting the assembly of the reduction mechanism 1 on the scraper, i.e. for assembling the all-in-one machine on the scraper. Taking an implementation manner as an example, as shown in fig. 6, the mounting structure includes a third mounting hole 16 disposed at the periphery of the speed reducer casing 11, and when the speed reducer needs to be assembled on the scraper, the third mounting hole 16 on the speed reducer casing 11 is aligned with the mounting hole on the scraper, and then the all-in-one machine is fixed on the scraper by means of matching between bolts and nuts.

As shown in fig. 7, in one application scenario, the all-in-one machine further comprises a junction box 10, and a third connecting structure 100 is provided at one side of the junction box 10. Correspondingly, a fourth connecting structure 101 is arranged on the first end face 115 of the speed reducer case 11, a fifth connecting structure 102 is arranged on the second end face 116, and the junction box 10 is assembled on the first end face 115 of the speed reducer case 11 through the detachable connection between the third connecting structure 100 and the fourth connecting structure 101, or assembled on the second end face 116 of the speed reducer case 11 through the detachable connection between the third connecting structure 100 and the fifth connecting structure 102. If the all-in-one machine is used as a machine head driving device of a scraper machine, the junction box 10 is assembled on the first end face 115 of the speed reducing shell 11, so that the junction box 10 cannot interfere with other devices of the scraper machine; if the all-in-one of this application uses for the tail drive device of scraping the trigger, then assemble junction box 10 at the second terminal surface 116 of reduction casing 11, make junction box 10 can not interfere other equipment of scraping the trigger, therefore this all-in-one that sets up the mode can still have the advantage that the commonality is strong when setting up junction box 10.

In the following, an implementation manner of assembling the junction box 10 on the speed reducer case 11 will be described as an example, and as shown in fig. 8 and 9, the third connecting structure 100 includes a connecting slot 20 disposed on one side of the junction box 10, a length direction of the connecting slot 20 is a width direction of the speed reducer case 11, and corresponding first connecting holes 200 are disposed on an upper side and an upper side of the connecting slot 20, respectively. The fourth connecting structure 101 includes a first connecting piece 21 disposed on the first end surface 115 of the speed reducing housing 11, the length direction of the first connecting piece 21 is the width direction of the speed reducing housing 11, and a second connecting hole 210 having a length along the height direction of the speed reducing housing 11 is disposed on the first connecting piece 21. The fifth connecting structure 102 includes a second connecting plate 22 disposed on the second end surface 116 of the speed reducer casing 11, the length direction of the second connecting plate 22 is the width direction of the speed reducer casing 11, and a third connecting hole 220 having a length along the height direction of the speed reducer casing 11 is disposed on the second connecting plate 22. When the junction box 10 is assembled at the first end surface 115, the first connection piece 21 is placed in the middle connection groove 20 with the first connection hole 200 corresponding to the position of the second connection hole 210, then the bolt is used to pass through the first connection hole 200 and the second connection hole 210, and finally the nut is used to cooperate with the bolt for fixing. When the junction box 10 is assembled at the second end face 116, the second connection piece 22 is placed in the connection groove 20 with the first connection hole 200 corresponding to the position of the third connection hole 220, and then the first connection hole 200 and the third connection hole 220 are penetrated with bolts, and finally nuts are engaged with the bolts to fix.

As shown in fig. 10, in one application scenario, the wiring chamber 24 is disposed at the top inside the motor housing 23, and the length direction, the width direction and the height direction of the wiring chamber 24 are the same as those of the deceleration housing 11. The first wiring bank 241 and the second wiring bank 242 are arranged on two sides of the wiring cavity 24 in the length direction, the same number of wiring terminals are arranged in the first wiring bank 241 and the second wiring bank 242, the corresponding wiring terminals are in short circuit, and the lead of the motor mechanism 2 is electrically connected with the wiring terminals in the first wiring bank 241 or the second wiring bank 242. When the motor mechanism 2 and the frequency conversion mechanism 3 are assembled on the speed reducing mechanism 1, the frequency conversion mechanism 3 is connected with a wiring terminal in a wiring bank which is closest to the frequency conversion mechanism 3; because the short circuit between the corresponding binding post in first wiring row and second wiring row, consequently no matter frequency conversion mechanism 3 connects the binding post in first wiring row or connects the binding post in second wiring row, all can realize the electric connection with the motor structure.
