Technical Field
[0001] This utility model relates to the field of equipment loading and unloading technology, specifically to an unloading device for explosion-proof equipment in mines. Background Technology
[0002] In underground coal mine operations, the loading and unloading of explosion-proof equipment such as explosion-proof switches and motors is crucial. Currently, loading and unloading operations are mainly carried out using hoists located in fixed positions within the underground roadways. The explosion-proof equipment is placed on an unloading platform, which is then raised and lowered within the mine using the hoists.
[0003] Currently, most explosion-proof equipment is placed in the unloading platform by using multiple screws on both sides of the platform to fix it. This requires rotating the screws multiple times to fix or disassemble the equipment, resulting in low loading and unloading efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a mine explosion-proof equipment unloading device. This mine explosion-proof equipment unloading device can lock or unlock all the top rods together by adjusting the screw to move the truncated cylinder and abutting the top pin. Only two rotations of the adjusting screw are needed to complete the fixing and disassembly of the explosion-proof equipment, which can greatly improve the loading and unloading efficiency of the explosion-proof equipment.
[0005] The technical solution of this utility model is implemented as follows:
[0006] An unloading device for explosion-proof equipment in a mine includes an unloading platform. Side doors are rotatably installed on the front and rear sides of the unloading platform. Locking pins that cooperate with the side doors are also installed on the front and rear sides of the unloading platform. The locking pins can control the opening or closing of the side doors. The interior of the unloading platform is used for loading or unloading explosion-proof equipment.
[0007] The unloading platform is equipped with a sliding positioning plate on each of its left and right sides. An adjustment seat is fixed at the center of the positioning plate. An adjustment screw is threaded into the interior of the adjustment seat. A truncated cone lock cylinder with a variable diameter is fixed at the end of the adjustment screw.
[0008] The positioning plate is also fitted with multiple top rods arranged in a circumferential array around the truncated cone lock cylinder. These top rods can tighten and fix both ends of the explosion-proof equipment. Each top rod is also fitted with a pin hidden inside the positioning plate. By adjusting the screw to move the truncated cone lock cylinder, the pin can be engaged to lock or unlock all the top rods together.
[0009] Using the above solution, the mine explosion-proof equipment unloading device can lock or unlock all the top rods together by adjusting the screw to move the truncated cone lock core and then engaging the top pin. Only two rotations of the adjusting screw are needed to complete the fixing and disassembly of the explosion-proof equipment, which can greatly improve the loading and unloading efficiency of the explosion-proof equipment.
[0010] In a preferred embodiment of an unloading device for mine explosion-proof equipment, the end of the top rod facing the explosion-proof equipment is rounded.
[0011] In order to better adapt to explosion-proof equipment, the above solution adopts a top rod with a round head, which can better match the explosion-proof equipment since the two ends of the explosion-proof equipment may be irregular and non-planar.
[0012] As a preferred embodiment of an unloading device for mine explosion-proof equipment, the top rod has multiple annular limiting grooves arranged in a linear array on its shaft, and the end of the top pin facing the top rod can extend into the annular limiting groove.
[0013] To further improve the fixing effect of the top rod, an annular limiting groove is opened on the top rod body using the above solution. When the pin extends into the annular limiting groove, the "slippage" phenomenon of the top rod can be avoided.
[0014] In a preferred embodiment of an unloading device for explosion-proof equipment in a mine, the end of the top pin facing the frustum lock cylinder is a smooth round head.
[0015] By adopting the above solution, in order to reduce the wear between the top pin and the truncated cylinder, a smooth round-headed top pin can effectively reduce the friction when it contacts the truncated cylinder.
[0016] As a preferred embodiment of an unloading device for explosion-proof equipment in mines, a cross handle is fixed at the end of the adjusting screw away from the truncated cone lock core.
[0017] By adopting the above solution, it is easier to rotate the adjusting screw by rotating the cross handle to make the adjusting screw rotate.
[0018] As a preferred embodiment of an unloading device for mine explosion-proof equipment, slide blocks are fixedly connected to the left and right sides of the positioning plate. The slide blocks are fitted with positioning bolts through threads. The unloading platform slides up and down along the positioning blocks and has multiple positioning holes arranged in a linear array on both sides. When the positioning bolts are fitted into the positioning holes, the positioning plate can be completely fixed.
[0019] To enhance the flexibility of the positioning plate, the above solution is adopted, and it is designed to slide up and down, which can adapt to explosion-proof equipment of different sizes, making it more flexible in application.
[0020] As a preferred embodiment of an unloading device for mine explosion-proof equipment, the top of the unloading platform is connected to four side lugs for lifting.
[0021] Using the above scheme, in order to facilitate the connection between the unloading platform and the hoist, a lifting chain is inserted through the side lugs and suspended on the hoist. The hoist then drives the unloading platform to move up and down within the mine.
[0022] After adopting the above technical solution, the beneficial effects of this utility model are:
[0023] 1. The mine explosion-proof equipment unloading device can lock or unlock all the top rods together by adjusting the screw to move the truncated cone lock core and then contact the top pin. Only two rotations of the adjusting screw are needed to complete the fixing and disassembly of the explosion-proof equipment, which can greatly improve the loading and unloading efficiency of the explosion-proof equipment.
[0024] 2. In order to better adapt to explosion-proof equipment, since the two ends of explosion-proof equipment may be irregular and non-planar, using a round-headed top rod can better adapt to the explosion-proof equipment;
[0025] 3. To further improve the fixing effect of the top rod, an annular limiting groove is opened on the top rod body. At this time, the pin extends into the annular limiting groove, which can prevent the top rod from "slipping". To improve the flexibility of fixing the anchor net, the clamp for holding the anchor net is set to a sliding type, which can be adjusted according to the spacing of the anchor net, making it more flexible in application.
[0026] 4. In order to reduce wear between the top pin and the truncated cylinder, a smooth round-headed top pin can effectively reduce the friction when it contacts the truncated cylinder.
[0027] 5. To make it easier to rotate the adjusting screw, it is more effortless to rotate the adjusting screw by turning the cross handle;
[0028] 6. To improve the flexibility of the positioning plate, it is designed to slide up and down, which can adapt to explosion-proof equipment of different sizes, making it more flexible in application.
[0029] 7. To facilitate the connection between the unloading platform and the hoist, a lifting chain is inserted through the side lugs and suspended on the hoist. The hoist then drives the unloading platform to move up and down within the mine. Attached Figure Description

Detailed Implementation
[0038] 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.
[0039] like Figures 1 to 6As shown, a mine explosion-proof equipment unloading device includes an unloading platform 1. Side doors 2 are rotatably mounted on the front and rear sides of the unloading platform 1. A locking pin 15, which works in conjunction with the side doors 2, is also installed on the front and rear sides of the unloading platform 1. The locking pin 15 controls the opening and closing of the side doors 2. The interior of the unloading platform 1 is used for loading or unloading explosion-proof equipment, which in the figure is an explosion-proof motor 3. Positioning discs 4, capable of sliding up and down, are installed on the left and right sides of the unloading platform 1. A fixed center is welded to the center of each positioning disc 4. An adjusting seat 5 is provided, and an adjusting screw 6 is threadedly fitted inside the adjusting seat 5. A variable-diameter frustum lock core 7 is fixed at the end of the adjusting screw 6. Multiple push rods 8 are also inserted into the positioning plate 4, arranged circumferentially around the frustum lock core 7. These push rods 8 can tighten and fix both ends of the explosion-proof equipment. A pin 9, hidden within the positioning plate 4, is installed between each push rod 8 and the frustum lock core 7. By adjusting the screw 6 and moving the frustum lock core 7, all push rods 8 can be locked or unlocked simultaneously by engaging the pin 9. This mine explosion-proof equipment unloading device, by adjusting the screw 6 and moving the frustum lock core 7, can lock or unlock all push rods 8 simultaneously by engaging the pin 9. Only two rotations of the adjusting screw 6 are needed to complete the fixing and disassembly of the explosion-proof equipment, greatly improving the loading and unloading efficiency of the explosion-proof equipment.
[0040] like Figures 4 to 6 As shown, the end of the push rod 8 facing the explosion-proof equipment has a rounded end. In order to better adapt to the explosion-proof equipment, since the two ends of the explosion-proof equipment may be irregular and non-planar, the rounded end of the push rod 8 can better match the explosion-proof equipment.
[0041] like Figures 4 to 6 As shown, the top rod 8 has multiple linearly arrayed annular limiting grooves 10 on its shaft, and the end of the top pin 9 facing the top rod 8 can extend into the annular limiting groove 10. In order to further improve the fixing effect of the top rod 8, the annular limiting groove 10 is opened on the shaft of the top rod 8. At this time, the pin extends into the annular limiting groove 10, which can prevent the top rod 8 from "slipping".
[0042] like Figures 4 to 6 As shown, the end of the top pin 9 facing the frustum lock cylinder 7 is a smooth round head. In order to reduce the wear between the top pin 9 and the frustum lock cylinder 7, the use of a smooth round head top pin 9 can effectively reduce the friction when it contacts the frustum lock cylinder 7.
[0043] like Figures 4 to 6 As shown, a cross handle 11 is welded and fixed to the end of the adjusting screw 6 away from the truncated cylinder 7. To facilitate the rotation of the adjusting screw 6, it is easier to rotate the adjusting screw 6 by rotating the cross handle 11.
[0044] like Figure 1 , Figures 4 to 6As shown, sliding blocks 12 are fixedly connected to the left and right sides of the positioning disk 4. Positioning bolts 13 are threaded into the interior of each sliding block 12. Multiple linearly arrayed positioning holes 14 are formed on both sides of the unloading platform 1 as it slides up and down along the positioning blocks. When the positioning bolts 13 are fitted into the positioning holes 14, the positioning disk 4 is completely fixed. To improve the flexibility of the positioning disk 4, it is designed to slide up and down, adapting to explosion-proof equipment of different sizes, making its application more flexible.
[0045] like Figure 1 As shown, the top of the unloading platform 1 has four side lugs 16 welded on for lifting. To facilitate the connection between the unloading platform 1 and the hoist, a lifting chain is inserted through the side lugs 16, and the lifting chain is suspended on the hoist. The hoist drives the unloading platform 1 to move up and down in the mine.
[0046] The working principle of this utility model:
[0047] When loading the explosion-proof motor 3, the workers approach the front of the unloading platform 1, open the side of the unloading platform 1, place the explosion-proof motor 3 inside the unloading platform 1, and then close the side, securing it with locking pins 15. Next, the workers approach the left and right sides of the unloading platform 1 and push the top rods 8 respectively, causing the top rods 8 on both sides of the unloading platform 1 to engage with the fixed sides of the explosion-proof motor 3. Then, by rotating the cross handle 11, the adjusting screw 6 moves the frustum lock core 7, which engages with the top pin 9, locking all the top rods 8 together, thus completing the fixation of the explosion-proof equipment. Finally, a lifting chain is inserted into the side lugs 16, suspending the chain onto the hoist, which then drives the unloading platform 1 to move up and down within the mine.
[0048] When unloading the explosion-proof motor 3, the steps are the same as loading, except that the cross handle 11 needs to be turned in the opposite direction during unloading. By adjusting the screw 6, the truncated cone lock core 7 can be moved to contact the top pin 9 and unlock all the top rods 8 together, thus completing the unloading of the explosion-proof equipment. In the above, only two rotations of the adjusting screw 6 are needed to complete the fixing and disassembly of the explosion-proof equipment, which can greatly improve the loading and unloading efficiency of the explosion-proof equipment.
[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
