[0034] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a high-voltage switch porcelain column docking and disassembly device, which includes a mounting base 100, a movable trolley 200, a lifting adjustment frame 300 and a lifting drive mechanism 400.

[0035] The mounting base 100 has a guide rail 110 extending in the front-rear direction.

[0036] like Figure 5 As shown, at least two movable trolleys 200 are provided, each of which can carry one porcelain column 101, thereby enabling the docking, installation, or disassembly of at least two porcelain columns 101. Of course, when the porcelain column 101 is long, multiple movable trolleys 200 can also be used to carry one porcelain column 101. The movable trolleys 200 are mounted on guide rails 110 and can move back and forth along the guide rails 110. The guide rails 110 are used to guide and limit the movement of the movable trolleys 200, so that the porcelain columns 101 on the movable trolleys 200 can be aligned to complete docking or disassembly.

[0037] Two lifting adjustment frames 300 are provided at intervals in front and back corresponding to each movable trolley 200. The lifting adjustment frames 300 are installed on the movable trolley 200 for lifting and movement. Two inclined rods 310 are provided at the upper end of the lifting adjustment frame 300. The two inclined rods 310 are arranged in a V shape to form a V-shaped bracket 311. The V-shaped bracket 311 is used to support the porcelain column 101.

[0038] Each lifting and adjusting frame 300 is provided with a lifting drive mechanism 400, thereby enabling independent lifting and adjustment of each lifting and adjusting frame 300. The lifting drive mechanism 400 is mounted on the movable carriage 200, and the upper end of the lifting drive mechanism 400 contacts the lifting and adjusting frame 300. The upper end of the lifting drive mechanism 400 can be raised and lowered to drive the lifting and adjusting frame 300 to move upward and downward.

[0039] The utility model provides a high-voltage switch porcelain column docking and disassembly device, which uses a V-shaped bracket 311 formed by two oblique rods 310 to support the porcelain column 101, so that the porcelain column 101 automatically aligns with the middle of the V-shaped bracket 311, and then uses the lifting and adjusting frame 300 to adjust the position to adjust the height of the porcelain column 101, so that when there is a height difference between adjacent porcelain columns 101, it can be adjusted so that the heights of adjacent porcelain columns 101 can be aligned. In addition, two lifting and adjusting frames 300 are provided on each movable trolley 200, which can effectively achieve stable support for the porcelain column 101, and the two lifting and adjusting frames 300 can be adjusted independently. When the diameter of the porcelain column 101 changes, the diameters of the positions where the porcelain column 101 is supported by the two lifting and adjusting frames 300 may be different, causing the porcelain column 101 to tilt. The porcelain column 101 is not in a horizontal state, which affects the stable support during subsequent docking installation or disassembly. The lifting and adjusting frames 300 can adjust the height. The porcelain column 101 can be kept horizontal by adjusting the height of the two lifting and adjusting frames 300. This device can disassemble or assemble the entire multi-segment porcelain column 101, and there is no need to disassemble or assemble the multi-segment porcelain column 101 at high altitudes. It can facilitate the docking or disassembly of porcelain bottles and does not require high-altitude operations. When disassembly is required, the entire multi-segment porcelain column 101 can be hoisted onto the movable trolley 200 to complete disassembly; when docking installation is required, the multi-segment porcelain column 101 can be placed on the movable trolley 200 to complete docking installation before the entire column 101 is hoisted to complete installation.

[0040] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the inclined surfaces on both sides of the V-shaped bracket 311 are installed with buffer pads 320 for contacting the porcelain column 101, thereby avoiding rigid support for the porcelain column 101, preventing the porcelain column 101 from colliding, squeezing, and wearing with the device, and reducing damage to the porcelain column 101. The buffer pads 320 can be made of rubber or polyurethane buffer materials.

[0041] Reference Figure 2 In some embodiments of the present invention, a slide groove 210 is provided on the left and right sides of the movable trolley 200, and the slide groove 210 extends vertically. Vertical rods 330 are provided on the left and right sides of the lifting adjustment frame 300. The vertical rods 330 are embedded in the slide groove 210 and can be lifted and lowered along the slide groove 210, thereby guiding the lifting and lowering of the lifting and adjusting frame 300, and the sliding guide position is set on both sides, so that the lifting and adjusting frame 300 is more stable when lifting.

[0042] Reference Figure 2In a further embodiment of the present invention, a horizontal bar 340 is provided at the bottom of the lifting and adjusting frame 300, and the vertical bar 330 is connected to the left and right ends of the horizontal bar 340. One end of the oblique bar 310 is connected to the upper end of the horizontal bar 340, and the other end is connected to the middle of the horizontal bar 340. The vertical bar 330 and the horizontal bar 340 are vertically connected, and the connection stability is insufficient. The oblique bar 310 can not only form a V-shaped bracket 311, but also strengthen the structure of the vertical bar 330 and the horizontal bar 340. The oblique bar 310 is connected to the vertical bar 330 and the horizontal bar 340 to form a triangular frame structure. The stabilizing effect of the triangle is utilized to effectively improve the overall structural strength and stability.

[0043] Reference Figure 4 In a further embodiment of the present invention, the vertical rod 330 is equipped with multiple guide wheels 350, and the multiple guide wheels 350 are respectively in contact with the front and rear side walls of the slide 210, so that the guide wheels 350 can roll along the front and rear side walls of the slide 210, that is, there are two groups of guide wheels 350, one group is in contact with the front side wall of the slide 210, and the other group is in contact with the rear side wall of the slide 210, thereby positioning the lifting and adjusting frame 300 in the front and rear directions, and through the rolling of the guide wheels 350, the friction force of the lifting and adjusting frame 300 is effectively reduced, the friction resistance is reduced, and the lifting and adjusting frame 300 is lifted and lowered more smoothly, the required force is smaller, and the operation is more convenient.

[0044] Reference Figure 2 In a further embodiment of the present invention, a group of vertical poles 220 are provided on the front and rear sides of the movable trolley 200, and the two vertical poles 220 in the same group are arranged at intervals on the left and right. Specifically, a vertical pole is provided at each of the four corners of the movable trolley 200, and a slide groove 210 is formed on the vertical pole 220. The opposite sides of the slide groove 210 on the two vertical poles 220 in the same group are open, so as to facilitate the vertical rod 330 to be embedded in the slide groove 210 and reduce structural interference.

[0045] Reference Figure 2 In a further embodiment of the present invention, two adjacent vertical poles 220 are connected by a longitudinal rod 230, thereby improving the structural strength of the vertical poles 220, reducing the deformation of the vertical poles 220, and improving the stability of the device load.

[0046] Reference Figure 2 In a further embodiment of the present invention, the bottoms of two vertical poles 220 in the same group are connected by a bottom pole 240. Two bottom poles 240 are spaced apart to correspond to the front and rear groups of vertical poles 220. The front and rear bottom poles 240 are also connected by connecting rods to form a frame structure, improving stability. The bottom pole 240 is located below the lifting adjustment frame 300, and the bottom of the lifting drive mechanism 400 is mounted on the bottom pole 240, thereby providing support for the lifting drive mechanism 400.

[0047] Reference Figure 1In some embodiments of the present invention, two guide rails 110 are provided at intervals along the left-right direction, and rollers 250 cooperating with the guide rails 110 are provided at the bottom of the movable trolley 200. Two groups of rollers 250 are provided at intervals along the left-right direction corresponding to the two guide rails 110. The rollers 250 facilitate the low-resistance movement of the movable trolley 200, and the two guide rails 110 improve the stability of the movable trolley 200.

[0048] Reference Figure 1 In some embodiments of the present invention, the lifting drive mechanism 400 is a jack, specifically a scissor jack. Of course, in other embodiments, the jack can also be other types of jacks. Furthermore, the lifting drive mechanism 400 can also use a telescopic drive mechanism such as an electric push rod to adjust the height and position of the lifting adjustment frame 300.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
