[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 As shown, a belt conveyor lifting and maintenance platform includes a base 1 and a support frame 2. A screw 6 is rotatably connected between the base 1 and the support frame 2. A drive structure 3 for rotating the screw 6 is provided inside the base 1. A connecting plate 7 is threadedly connected to the surface of the screw 6. A fixed platform 8 is fixedly connected to the left side of the connecting plate 7. A worktable 9 is fixedly connected to the top of the fixed platform 8. A through groove 10 is opened at the bottom of the worktable 9. A cover plate 11 is hinged to the surface of the through groove 10. A receiving plate 12 is provided inside the fixed platform 8. A receiving groove 4 is opened at the top of the receiving plate 12. Several teeth 13 are fixedly connected to both sides of the bottom of the receiving plate 12. A first motor 14 is fixedly fixed to the surface of the fixed platform 8. A transmission rod 15 is fixedly connected to the output shaft of the first motor 14. The other end of the transmission rod 15 is rotatably connected to the inner wall of the fixed platform 8. Gears 16 are fixed to both sides of the surface of the transmission rod 15. The gears 16 mesh with the receiving plate 12 through the teeth 13.

[0022] The drive structure 3 includes a second motor 31, a first bevel gear 32, and a second bevel gear 33. The second motor 31 is fixed inside the base 1. The output shaft of the second motor 31 is fixedly connected to one side of the first bevel gear 32. The interior of the second bevel gear 33 is fixed to the bottom of the surface of the screw 6. One side of the second bevel gear 33 meshes with one side of the first bevel gear 32. When it is necessary to drive the screw 6 to rotate, the second motor 31 can be started, which will drive the first bevel gear 32 to rotate and simultaneously drive the second bevel gear 33 to rotate, thereby driving the screw 6 to rotate, so as to subsequently drive the connecting plate 7, the fixed platform 8, and the worktable 9 to move up and down.

[0023] T-slots are provided at the front and rear of the top of the inner cavity of the fixed platform 8, and T-sliders 17 are slidably connected inside the T-slots. The bottom end of the T-sliders 17 is fixedly connected to the top of the receiving plate 12. Through the sliding connection between the surface of the T-sliders 17 and the inside of the T-slots, the stability of the receiving plate 12 during movement can be improved, which facilitates better subsequent material receiving.

[0024] A retaining plate 18 is fixedly connected to the left side of the rear wall of the inner cavity of the workbench 9, and a buckle 19 is fixedly connected to the top of the cover plate 11. The buckle 19 works in conjunction with the interior of the retaining plate 18. When the cover plate 11 is opened, the buckle 19 can enter the retaining plate 18, thereby limiting the cover plate 11 and preventing it from deflecting randomly after it is opened.

[0025] The surface of the receiving trough 4 is provided with a buffer pad 5, and the size of the buffer pad 5 is adapted to the size of the receiving trough 4. When the part falls into the inside of the receiving plate 12, the buffer pad 5 can buffer the falling part and prevent the part from splashing out.

[0026] Fixed rods 20 are fixed on both the front and rear sides of the top of the base 1. The surface of the fixed rods 20 is slidably connected to the outer side of the connecting plate 7. When the connecting plate 7 moves up and down, the fixed rods 20 can slide to the outer side of the connecting plate 7 to assist in limiting the movement of the connecting plate 7, thus facilitating its up and down movement.

[0027] Working principle: When the worker needs to repair the belt conveyor, the platform can be moved to the repair position. The worker can then pull the door handle on the surface of the workbench 9, enter the workbench 9, and bring the tools needed for repair. The drive structure 3 drives the screw 6 to rotate, which in turn moves the connecting plate 7, the fixed platform 8, and the workbench 9 upwards until they reach the repair position. Then, the first motor 14 is started, which drives the transmission rod 15 and the gear 16 to rotate. As the gear 16 rotates, the teeth 13 drive the receiving plate 12 to move towards the belt conveyor, so that the receiving plate 12 is located below the repair area. If parts or tools fall during the repair process, they can be caught by the receiving plate 12. When retrieving the tools or parts that have fallen inside the receiving plate 12, the receiving plate 12 is moved back to the inside of the fixed platform 8. Then, the cover plate 11 is opened, and the parts or tools in the receiving plate 12 are retrieved by passing through the through groove 10.
