Description

Technical Field

[0001] The present application relates to the technical field of electric control box auxiliary parts, and in particular to a bottom-supporting electric control box cover sliding device. Background Art

[0002] The electric control box contains one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, and is completely assembled together with structural components by the manufacturer. In the coal mine, the coal mining machine needs to be connected to the electric control box, but due to the limitations of the design environment, the coal mining machine electric control box is usually directly installed in the coal mine.

[0003] In order to ensure the structural strength and sealing of the coal mining machine in the coal mine, the electric control box cover is usually connected mainly by bolts rather than hinges. However, the electric control box of the coal mining machine needs to be opened and maintained frequently in the coal mine, which makes the heavy electric control box cover difficult to carry and inconvenient to maintain during the opening and closing process underground. Summary of the invention

[0004] In order to facilitate the opening and closing of the cover of the electric control box in the coal mine, the present application provides a bottom-supporting electric control box cover sliding device.

[0005] The present application provides a bottom support type electric control box cover sliding device adopts the following technical solution:

[0006] A bottom-supporting electric control box cover sliding device comprises a receiving platform for fixedly connecting with the electric control box, the receiving platform is provided with a receiving track for transporting the electric control box cover, the receiving platform is rotatably connected with a plurality of rollers, the axes of the rollers are located in the same plane and are all arranged parallel to each other.

[0007] By adopting the above technical scheme, the receiving platform is connected with the electric control box. After the cover of the electric control box is removed from the electric control box by bolts, the cover is moved along the receiving track to the rollers, and then the cover is moved along the distribution direction of the rollers to complete the operation of opening the cover. Compared with the manual disassembly method, the weight of the cover is borne by the rollers to avoid manual support, and during the movement of the cover, the sliding friction generated during the movement is converted into rolling friction by the rollers, thereby further reducing the resistance and facilitating the disassembly process of the cover of the electric control box.

[0008] Optionally, the receiving rail, the receiving platform and the several rollers thereon constitute a single module, and the receiving platform is respectively provided with docking grooves and docking blocks at both ends along the arrangement direction of the several rollers, and the docking grooves and docking blocks of the receiving platforms of the two modules are embedded.

[0009] By adopting the above technical solution, several modules are combined through the docking grooves and docking blocks on the receiving platform, so that a longer conveying range is formed through the combination to adapt to electric control boxes of different specifications, thereby improving the application range of the sliding device.

[0010] Optionally, a safety limit block is fixedly arranged between the two rollers, and the safety limit block is fixedly connected to the receiving platform.

[0011] By adopting the above technical solution, a safety limit block is arranged between the two rollers, so that when the rollers are damaged, the safety limit block can bear the weight of the cover plate to prevent the cover plate from falling freely.

[0012] Optionally, the roller is coaxially rotatably connected with the pin shaft, the supporting platform is fixedly provided with a plurality of slide rails, the pin shaft is fixedly connected to the supporting block, the supporting block is slidably connected to the slide rails, and the supporting platform is fixedly provided with return springs tightly pressed against opposite sides of the supporting block at both ends of the slide rails.

[0013] By adopting the above technical solution, two return springs are used to provide a certain movement range for the receiving block to guide along the slide rail. When the cover of the electric control box is pressed on the roller, the roller will drop a certain distance under the action of the return spring to prevent the cover from falling directly onto the roller under the action of gravity, which would cause a large impact due to the impulse in a short period of time and lead to damage to the roller.

[0014] Optionally, a supporting rod is arranged between the two supporting blocks, and the supporting rod includes two connecting rods rotatably connected to the supporting blocks, and a cylindrical guide rod is arranged between the two connecting rods. The guide rod is coaxially fixedly connected to one of the connecting rods, and the other connecting rod is coaxially passed through the guide rod, and a limit spring is embedded in the guide rod and is coaxially fixedly connected to the two connecting rods.

[0015] By adopting the above technical solution, a receiving rod is set between the two receiving blocks, so that when the receiving block is indirectly subjected to the pressure of the cover plate of the electric control box, it moves downward. At the same time, the adjacent receiving blocks between the receiving blocks that move downward are caused to move downward a short distance through the connecting rod, the guide rod and the limit spring, so as to achieve the effect of pre-downward movement. In this way, the height difference between the rollers is reduced in the process of moving the cover plate along the distribution direction of the rollers, making the rollers more convenient during transportation.

[0016] Optionally, a bracket is provided on the side of the roller facing away from the receiving platform, the bracket is fixedly connected to the receiving platform, and the height of the bracket is higher than the roller.

[0017] By adopting the above technical solution, the bracket and the receiving platform form a channel, and the rollers are distributed in the channel, so that the cover of the electric control box is limited by the channel during transportation on the rollers, preventing the cover from slipping and causing the cover to derail.

[0018] Optionally, the electric control box is also fixedly provided with a limiting track for limiting the cover plate to slide unidirectionally onto the roller, the limiting track is arranged opposite to the receiving platform, and the electric control box cover plate is tightly against the receiving platform and the limiting track at the same time.

[0019] By adopting the above technical solution, the limiting track and the receiving platform limit the cover of the electric control box from the opposite sides thereof, so that the movement of the cover is limited before the cover enters the track formed by the roller combination, thereby preventing the posture of the cover from changing when the cover is transported to the rollers.

[0020] Optionally, a sliding groove is provided on one side of the limiting rail that is close to the cover of the electric control box, and the sliding groove is opened toward the receiving platform. A sliding block is arranged in the sliding groove, and the sliding block is a trapezoidal block, and its inclined surface is arranged close to the cover of the electric control box. A compression spring is also fixedly arranged on the sliding block, and one end of the compression spring is fixedly connected to the limiting rail, and the other end is fixedly connected to the sliding block. The compression spring applies a force to the sliding block away from the receiving platform. A handle is also provided on the sliding block, and a sliding groove is provided on the side wall of the limiting rail, the handle passes through the sliding groove, and is slidably connected along the slotting direction of the sliding groove, and the sliding groove extends toward the receiving platform.

[0021] By adopting the above technical solution, a sliding block is set in the sliding groove, and the sliding block is always located inside the sliding groove due to the action of the compression spring. However, the sliding block can be indirectly moved by moving the handle along the direction of the sliding groove to make it leave the sliding groove, and the inclined surface of the sliding block can be used to push the cover of the electric control box to move onto the roller to facilitate the movement of the cover.

[0022] Optionally, a plurality of through holes are formed on the receiving rail, and the through holes are arranged in the same direction and toward the roller.

[0023] By adopting the above technical solution, a number of through holes are opened on the receiving track to reduce the contact area between the electric control box cover and the receiving track, thereby reducing the friction resistance between the cover and the receiving roller, making the movement of the cover more labor-saving.

[0024] Optionally, the connections among the receiving rail, the receiving platform and the roller are smoothly arranged.

[0025] By adopting the above technical solution, the connection between the receiving track, the receiving platform and the roller is smoothly arranged to reduce the collision effect between the three during the movement of the cover plate and avoid deformation damage to the cover plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By setting a receiving platform, receiving track and rollers on the side wall of the electric control box, the cover of the electric control box can be placed on the rollers for auxiliary transportation, so that when the electric control box is disassembled, the cover can be transported quickly and conveniently;

[0028] 2. By setting the reset spring and the slide rail, the receiving block can slide along the slide rail. When the cover plate falls onto the roller, the contact time between the two is increased, thereby protecting the roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The embodiment of the present application discloses a bottom-supporting electric control box cover sliding device.

[0037] Reference Figure 1 , Figure 2 and Figure 3A bottom-supporting electric control box cover sliding device includes a receiving platform 1 for fixed connection with the electric control box. The electric control box is rectangular and placed horizontally. A rectangular opening is opened on a vertical plane thereof. The opening is covered with a cover plate, which is fixedly connected to the side wall of the electric control box by bolts. The receiving platform 1 is horizontally arranged and fixedly connected to the side wall of the electric control box by bolts. A receiving rail 2 for transporting the cover of the electric control box is fixedly connected to the top surface thereof by bolts. The receiving rail 2 is also horizontally arranged, and the disassembled cover plate is horizontally located on the receiving rail 2. A plurality of through holes are opened on the receiving rail 2, and the through holes are opened upward, and the direction of each through hole is away from the electric control box.

[0038] A plurality of rollers 3 are rotatably connected to the receiving platform 1 on one side away from the electric control box. The axes of the rollers 3 are located in the same horizontal plane and are parallel and equidistantly distributed. The receiving track 2, the receiving platform 1 and the plurality of rollers 3 thereon constitute a single module. The receiving platform 1 is provided with docking grooves 4 and docking blocks 5 at both ends along the arrangement direction of the plurality of rollers 3. The docking grooves 4 and docking blocks 5 of the receiving platforms 1 of the two modules are interlocked to enable combination between multiple modules.

[0039] A safety limit block 6 is fixedly arranged between the two rollers 3. The safety limit block 6 is arranged horizontally and fixedly connected to the receiving platform 1. An L-shaped bracket 15 is arranged on the side of the roller 3 away from the receiving platform 1. The bracket 15 is fixedly connected to the receiving platform 1. The height of the bracket 15 is higher than the roller 3, so that when the cover plate is input from the receiving track 2 to the roller 3, the bracket 15 and the receiving platform 1 limit the cover plate to prevent it from tipping over. The connection between the receiving track 2, the receiving platform 1 and the roller 3 is chamfered and smooth.

[0040] The roller 3 is coaxially rotatably connected with the pin shaft 7, and a plurality of slide rails 9 are fixedly provided on the receiving platform 1, and the slide rails 9 are guided in the vertical direction. The pin shaft 7 is horizontally fixedly connected to the receiving block 8, and the receiving block 8 is slidably connected to the slide rails 9. Reset springs 10 are fixedly provided at both ends of the slide rails 9 on the receiving platform 1, tightly against the upper and lower opposite sides of the receiving block 8, one of the reset springs 10 is fixedly connected to the receiving platform 1, and the other reset spring 10 is fixedly connected to the receiving rail 2.

[0041] Reference Figure 2 , Figure 3 and Figure 4A supporting rod 11 is also provided between the two supporting blocks 8. The supporting rod 11 includes two connecting rods 12 rotatably connected to the supporting blocks 8. A cylindrical guide rod 13 is provided between the two connecting rods 12. The guide rod 13 is coaxially fixedly connected to one connecting rod 12, and the other connecting rod 12 is coaxially penetrated in the guide rod 13. A limit spring 14 is buried in the guide rod 13 and is coaxially fixedly connected to the two connecting rods 12. Through the above arrangement, when a roller 3 is subjected to cover pressure, its supporting block 8 moves downward and drives the guide rod 13 to extend, but the guide rod 13 will be subjected to a reset force under the action of the limit spring 14. At this time, a vertical downward component force will be applied to the adjacent supporting block 8 that is not subjected to the pressure of the supporting block 8, thereby causing it to move down a certain distance, so that the cover plate can slide on the slideway formed by each roller 3 through its lateral fillet during the sliding process.

[0042] The electric control box is also fixed with a limiting track 16 for limiting the cover plate to slide unidirectionally onto the roller 3. The limiting track 16 is arranged parallel to the receiving platform 1, and is arranged opposite to the receiving platform 1 and is located directly above the receiving platform 1. The upper and lower sides of the electric control box cover plate are tightly against the receiving platform 1 and the limiting track 16 at the same time.

[0043] A sliding groove 17 is provided on one side of the limiting rail 16 that is close to the cover of the electric control box. The sliding groove 17 is opened in the vertical direction and is opened toward the receiving platform 1. A sliding block 18 in the form of a trapezoidal block is provided in the sliding groove 17, and its inclined surface is arranged toward the receiving platform 1. A compression spring 19 is also fixedly provided on the sliding block 18. One end of the compression spring 19 is fixedly connected to the sliding groove 17 of the limiting rail 16, and the other end is fixedly connected to the sliding block 18. The compression spring 19 applies a force in the vertical upward direction to the sliding block 18. A handle 20 is also provided on the sliding block 18. A sliding groove 21 is provided on the side wall of the limiting rail 16. The handle 20 passes through the sliding groove 21 and is slidably connected along the length direction of the sliding groove 17.

[0044] The implementation principle of a bottom-supporting electric control box cover sliding device in an embodiment of the present application is: first, the receiving platform 1 of each module is assembled and the corresponding components are installed, and then the receiving platform 1 and the limiting rail 16 are installed on the side wall of the electric control box. During use, the cover is first slid on the receiving guide rail for a certain distance, and then the handle is pressed down, and the sliding block 18 is used to push the cover until the cover is completely placed on the roller 3, and then the cover is moved along the distribution direction of the roller 3, and then the electric control box is repaired.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
