Description

Technical Field

[0001] The invention relates to the technical field of self-moving devices, in particular to a tail self-moving device of a rail-type mining belt conveyor. Background Art

[0002] The rail-type mining belt conveyor is a device used for continuous transportation of large quantities of materials. It can be widely used in industries such as mining, building materials, chemicals, metallurgy and food. It consists of several conveyor units connected together, and each unit is connected by a connector to form a continuous conveyor line. The tail self-moving device is a device used to adjust the position of the end of the conveyor. In some cases, the end of the conveyor needs to be adjusted to adapt to the actual situation of the workplace, such as changes in the mining process or changes in the demand for conveyed materials.

[0003] The existing self-moving device at the tail of the mining rail-type mining belt conveyor is mainly used to move the tail of the conveyor to a suitable position. During the movement of the tail self-moving device, the tracks arranged on both sides of the self-moving device need to be transported forward along the ground. However, since the tracks are mostly in direct contact with the ground in the mine tunnel, and the ground in the mine tunnel accumulates a lot of material debris due to the material transportation, resulting in an uneven ground, which makes the track unstable during the contact with the ground. Since the track is the supporting and moving structure of the tail self-moving device of the mining belt conveyor, the tail self-moving device of the mining belt conveyor is unstable during the movement. Most of the existing self-moving devices do not have the function of automatically cleaning the road surface, which affects the normal operation of the tail self-moving device.

The inner walls of the multiple limit plates 402 are respectively slidably connected to the outer surfaces of the two slide rails 3. Two rollers 401 are rotatably connected between the opposite inner walls of the multiple limit plates 402. Hydraulic rods 403 are arranged on the tops of the multiple limit plates 402.

The outer surfaces of the multiple connecting blocks 404 are respectively fixedly connected to the opposite outer surfaces of the tail body 2. The opposite outer surfaces of the tail body 2 are arranged with sliding components 5. The two sliding components 5 include fixed blocks 501. The outer surfaces of the two fixed blocks 501 are provided with mounting grooves 502. The two mounting grooves 502 A connecting pipe 503 is fixedly installed between the opposite inner walls, and a rotating block 504 is movably sleeved on the outer surfaces of the two connecting pipes 503. A bidirectional electric push rod 505 is arranged on the outer surfaces of the two rotating blocks 504. Two mounting blocks 506 are fixedly installed on the outer surfaces of the two slide rails 3. Four mounting blocks 506 form a group of two. A limiting pipe 507 is fixedly connected between the outer surfaces of each group of mounting blocks 506. The outer surfaces of the two limiting pipes 507 are rotatably sleeved with a bearing block 508. One end of the two bidirectional electric push rods 505 is fixedly connected to the outer surfaces of the two bearing blocks 508 respectively. A first cylinder 11 is arranged near the edges of both sides at the bottom of the tail body 2, and the bottom ends of the two first cylinders 11 are fixedly connected to the supporting blocks 12. ;

[0035] In this embodiment, when the tail part of the mining belt conveyor needs to be moved, the external mining belt conveyor is first connected to the tail body 2, and then the multiple hydraulic rods 403 are started to extend them, driving the tail body 2 to move upward, and then the two first cylinders 11 are started to extend them, driving the two support blocks 12 to move downward until the bottoms of the two support blocks 12 contact the tops of the bottom plate 1, wherein the bottom plate 1 in this application refers to the road surface of the mine shaft, wherein the road surface of the shaft is relatively long. After the two support blocks 12 contact the bottom plate 1, the two hydraulic rods 403 are started again to shorten them, driving the two slide rails 3 to separate from the ground, and then the two bidirectional electric push rods 505 are started to shorten them, driving the bearing block 508 to move in the direction of the fixed block 501, thereby driving the two installation blocks 12 to move downward. The mounting block 506 moves toward the direction of the fixed block 501, thereby driving the two slide rails 3 to move toward the direction of the fixed block 501, thereby realizing the movement of the slide rails 3. When the movement of the slide rails 3 is completed, the two first cylinders 11 are started to shorten them, driving the two support blocks 12 to move to the top of the bottom plate 1, and the multiple hydraulic rods 403 are started again to extend them, driving the two slide rails 3 to move downward until they contact the top of the bottom plate 1, so that the rollers 401 are just embedded in the outer surface of the slide rails 3, and then the two-way electric push rod 505 is started to extend it, driving the end connected to the connecting pipe 503 to move forward, pushing the two limit plates 402 to move toward the direction of the stop rod 7, and then driving the tail body 2 to move forward along the two slide rails 3, that is, completing the movement of the tail body 2 and the slide rails 3, wherein, as Figure 4 As shown, the two ends of the bidirectional electric push rod 505 are movably connected to the fixed block 501 and the mounting block 506 through the connecting tube 503 and the bearing block 508, respectively, in order to facilitate the extension and retraction of the bidirectional electric push rod 505. When the two slide rails 3 rise, the blocking rod 7 is driven to move upward, thereby driving the connecting rod 605 to move upward. The inner diameter of the connection between the connecting rod 605 and the support rod 617 is larger than the outer diameter of the support rod 617, in order to facilitate the lifting and lowering of the connecting rod 605. The rising of the connecting rod 605 drives the rotating plate 60 4 moves upward, and according to the lever principle, the other end of the rotating plate 604 rotates downward, thereby causing the mounting rod 610 to rotate downward. Since the mounting rod 610 and the mounting tube 607 are rotationally connected, the bottom of the mounting rod 610 is always perpendicular to the top of the bottom plate 1 under the action of its own gravity. When the two slide rails 3 rise to the maximum height, the first forward and reverse motor 606 is started to drive the mounting tube 607 to rotate, thereby driving the two screw rods 608 to rotate, thereby causing the two nuts 609 to move toward each other. Figure 7As shown, the thread directions of the two screw rods 608 are opposite, wherein the bearing tube 618 limits the two nuts 609 so that they can only move horizontally along the direction of the mounting tube 607. In addition, the length of the mounting rod 610 is consistent with the distance between the two screw rods 608. When the two nuts 609 move to tightly contact the two ends of the mounting rod 610, the mounting rod 610 is fixed to prevent it from being rotated by external force during the later cleaning of the top of the bottom plate 1. When the two slide rails 3 move forward, the mounting rod 610 is started. Multiple suction fans 616 are driven to form negative pressure between the top of the base plate 1 and the mounting sleeve 614. Under the action of the negative pressure, the debris particles retained on the top of the base plate 1 are sucked upward and enter the groove 612 inside the storage rod 611 through the curved pipe 613, thus completing the cleaning of the debris in the shaft. This makes the road surface smoother during the subsequent forward movement of the slide rail 3, thereby making the movement of the tail self-moving device more stable, thus solving the problem in the prior art that the large amount of debris on the inner wall of the mine shaft easily leads to unstable movement of the tail self-moving device. Embodiment 2

[0036] like Figure 1 , Figure 4 and Figure 9-10 As shown, the outer surface of the storage rod 611 is provided with a moving assembly 8, and the moving assembly 8 includes a coil spring housing 801, the outer surface of the coil spring housing 801 is fixedly connected to the outer surface of the storage rod 611, and the inner wall of the coil spring housing 801 is provided with a slot 802, and the interior of the slot 802 is rotatably connected to a limiting column 803, and a vortex spring 804 is arranged inside the slot 802, and one end of the vortex spring 804 is fixedly connected to the outer surface of the limiting column 803, and a take-up roller 805 is fixed to one end of the limiting column 803, and the other end of the vortex spring 804 is connected to the outer surface of the take-up roller 805.

[0037] In this embodiment, after the cleaned waste residue enters the interior of the groove 612, the second forward and reverse motor 809 is started to drive the winding rod 810 to rotate, and then the external connecting rope 811 is wound around the surface of the winding rod 810, thereby driving the push plate 807 to move in the direction of the fixed frame 808, thereby pushing the debris to the outside of the groove 612. When the push plate 807 moves to the outer edge of the groove 612, the debris retained in the groove 612 can be cleaned out. At the same time, when the push plate 807 moves in the direction of the fixed frame 808, it also drives the connecting line 806 to move with the push plate 807, thereby compressing the vortex spring 804. And restricted by the connecting rope 811, the push plate 807 can only move to the point where the outer surface is flush with the outer surface of the groove 612, and then the second forward and reverse motor 809 is turned off, wherein the second forward and reverse motor 809 does not have The utility model is equipped with a self-locking function. When it is closed, the winding rod 810 can still rotate. At this time, the spiral spring 804 releases the potential energy to pull the connecting line 806 to reset, thereby driving the push plate 807 to move to the other side edge of the groove 612. The length of the connecting rope 811 is consistent with the length of the connecting line 806. When the push plate 807 moves to the other side edge of the groove 612, the second forward and reverse motor 809 is started again, and the debris retained in the groove 612 is cleaned into the shaft in this way. The length of the storage rod 611 is greater than the distance between the chain slide rails 3, so that the debris is cleaned and the debris is prevented from clogging the groove 612 and affecting the adsorption of the debris. Through the action of the moving component 8, the efficiency of the cleaning component 6 in cleaning the debris in the shaft is further improved. The coil spring shell 801 is an existing mature technology and will not be introduced in detail here. Embodiment 3

When the pressing roller 1004 moves to be in tight contact with the top of the bottom plate 1, the pressing roller 1004 rotates under the action of friction, thereby compacting the inside of the shaft, thereby making the contact surface between the two slide rails 3 and the ground smoother, further improving the stability of the tail self-moving device.

When the two nuts 609 move to tightly contact the two ends of the mounting rod 610, the mounting rod 610 is fixed. When the two slide rails 3 move forward, multiple suction fans 616 are started to form a negative pressure between the top of the bottom plate 1 and the mounting sleeve 614. Under the action of the negative pressure, the debris particles retained on the top of the bottom plate 1 are absorbed upward and enter the groove 612 inside the storage rod 611 through the curved pipe 613, thus completing the cleaning of the debris in the well, so that the road surface is smoother during the later movement of the slide rail 3, and the movement of the tail self-moving device is more stable.When the cleaned waste residue enters the interior of the groove 612, the second forward and reverse motor 809 is started to drive the winding rod 810 to rotate, and then the external connecting rope 811 is wound around the surface of the winding rod 810, thereby driving the push plate 807 to move in the direction of the fixed frame 808, thereby pushing the debris to the outside of the groove 612. When the push plate 807 moves to the outer edge of the groove 612, the debris retained in the groove 612 can be cleaned out. At the same time, when the push plate 807 moves in the direction of the fixed frame 808, it also drives the connecting line 806 to move with the push plate 807, thereby compressing the spiral spring 804. Restricted by the connecting rope 811, the push plate 807 can only move to the point where the outer surface is flush with the outer surface of the groove 612, and then the second forward and reverse motor is turned off. The vortex spring 804 releases its potential energy to pull the connecting line 806 back to its original position, thereby driving the push plate 807 to move to the other side edge of the groove 612. When the push plate 807 moves to the other side edge of the groove 612, the second forward and reverse motor 809 is started again, and the debris trapped in the groove 612 is cleaned into the well. After the debris on the road surface is cleaned, in order to make the road surface smoother, the two second cylinders 1001 are started to drive the lifting frame 1002 to move downward, thereby driving the pressing roller 1004 to move downward. When the pressing roller 1004 moves to tightly contact the top of the bottom plate 1, the pressing roller 1004 rotates under the action of friction, thereby compacting the inside of the well, thereby making the contact surface between the two slide rails 3 and the ground smoother.
