Description

Technical Field

[0001] This utility model relates to the field of temporary storage and maintenance technology for high-voltage bushings, specifically a quick-assembly and splicing bushing maintenance and storage bracket. Background Technology

[0002] In on-site maintenance of power equipment, high-voltage bushings often need to be removed from the equipment and temporarily placed on the ground. Without proper stabilization, the outer insulating porcelain sleeves of the bushings can easily be damaged, leading to safety hazards in the high-voltage equipment. Currently, the common method for placing high-voltage bushings on the ground is to elevate both ends with long wooden sleepers and secure them with triangular wooden blocks to prevent lateral sliding. However, since sleepers and triangular wooden blocks are not readily available tools, in practice, a few random wooden sticks are often used instead, which is not only unprofessional but also easily damages the high-voltage bushings. According to regulations, if bushings are laid horizontally during on-site testing or maintenance, they must be left upright and stationary for one day before reinstallation. This significantly reduces the efficiency of transformer maintenance or repair. Utility Model Content

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a technical solution:

[0031] The quick-assembly splicing sleeve maintenance and storage rack includes a frame 2, a support platform 3, and legs 4. The structure and working principle of the frame 2, support platform 3, and legs 4 are explained in detail below.

[0032] The frame 2 forms a vertical accommodating space with an open top. The sleeve 1 (sleeve 1 is the high-pressure sleeve) can be vertically inserted into the accommodating space through the opening. The vertical height of the frame 2 is greater than the distance between the flange 11 of the sleeve 1 and the bottom surface of the sleeve 1. Since the frame 2 works with the support platform 3 to support the flange 11 in the middle of the sleeve 1, so that the bottom end of the sleeve 1 is suspended inside the accommodating space, when the vertical height of the frame 2 is greater than the distance between the flange 11 of the sleeve 1 and the bottom surface of the sleeve 1, it can effectively prevent the bottom end of the sleeve 1 from contacting the ground and prevent the bottom end of the sleeve 1 from being damaged due to contact with the ground.

[0033] Furthermore, the frame 2 includes four vertical rods 21 and several layers of horizontal frames 22. In this embodiment, both the vertical rods 21 and the horizontal frames 22 can be made of aluminum alloy profiles. The specific model, specifications, or dimensions of the aluminum alloy profiles are not limited here. For different models of sleeves 1, aluminum alloy profiles of appropriate models, specifications, or dimensions can be selected to assemble the frame 2. Each layer of horizontal frame 22 includes four horizontal rods 221 arranged in a rectangular pattern. The two ends of each horizontal rod 221 are fixedly connected to two vertical rods 21 respectively. The accommodating space is located between the four vertical rods 21. The accommodating space is surrounded by the horizontal frames 22, so that the horizontal frames 22 can block physical impacts from outside the accommodating space to protect the part of the sleeve 1 located inside the accommodating space.

[0034] The support platform 3 is located on top of the frame 2 and is used to support the flange 11. The support platform 3 includes two support members 31 that are assembled and connected, forming a channel between the two support members 31 for the sleeve 1 to pass through. In actual operation, the sleeve 1 is hoisted by a crane to the top of the support member 31. At this time, the sleeve 1 is kept vertical. Then, the two support members 31 are gradually opened and separated to both sides until the distance between the two support members 31 will not hit the sleeve 1 during the descent of the sleeve 1. Then, the sleeve 1 is slowly lowered by the crane until the flange 11 of the sleeve 1 is lowered to a height slightly higher than the upper surface of the support member 31. The two support members 31 are then assembled and connected to form a complete support platform 3, and the two support members 31 are locked and fixed with a lock. Then, the sleeve 1 is slowly lowered by the crane again until the bottom surface of the flange 11 presses against the upper surface of the support platform 3. At this time, the sleeve 1 passes through the channel formed between the two support members 31, and the support platform 3 provides stable support for the flange 11 and the sleeve 1.

[0035] Furthermore, the support member 31 includes a first plate 311 and a second plate 312 arranged at opposite ends, and a connecting plate 313 fixed between the first plate 311 and the second plate 312. The first plate 311 and the second plate 312 are both semi-circular rings, and the first plate 311, the second plate 312, and the connecting plate 313 can all be made of stainless steel. The outer diameter of the first plate 311 is smaller than the outer diameter of the second plate 312. In this way, the support platform 3 assembled by the two support members 31 can be in the shape of a frustum with a smaller top and a larger bottom. The center of the frustum forms a channel for the sleeve 1 to pass through.

[0036] Furthermore, the support member 31 is slidably mounted on the top of the frame 2 via a linear slide rail 5; there are two linear slide rails 5, which are respectively mounted on two horizontal bars 221 located on the top of the vertical bar 21 and arranged opposite each other; both ends of the linear slide rail 5 are fixed with limit plates, which are used to limit the sliding range of the support member 31 and prevent the support member 31 from falling off the linear slide rail 5.

[0037] The support legs 4 are located at the bottom of the frame 2; four support legs 4 are provided and extend horizontally to the outside of the frame 2; specifically, each support leg 4 includes a nested first tube 41 and second tube 42 and a positioning pin 43. The first tube 41 and second tube 42 can be square tubes; the first tube 41 is fixedly connected to the frame 2; the second tube 42 can slide telescopically relative to the first tube 41; the positioning pin 43 is used to fix the position of the second tube 42; the first tube 41 and the second tube 42 are each provided with a number of corresponding positioning holes. The positioning pin 43 can pass through the two positioning holes after the positioning holes on the first tube 41 and the positioning holes on the second tube 42 are aligned to limit the relative position of the first tube 41 and the second tube 42; the free end of the second tube 42 is threadedly connected to a vertically arranged support foot 44.

[0038] Furthermore, the second tube 42 can be completely pulled out from the first tube 41. For example, taking the example of four legs 4 at the bottom of each frame 2, when it is necessary to assemble and splice the two frames 2 in the horizontal direction to facilitate the simultaneous placement of two sleeves 1, the second tubes 42 on the two legs 4 located at the bottom of the frame 2 and on the same side can be pulled out from their respective first tubes 41, and then the two frames 2 can be assembled and spliced ​​together. At this time, the bottom of the two frames 2 is still supported by the four legs 4.

[0039] In addition, to facilitate the maintenance work of the staff, hooks are installed on the edge of frame 2 so that ladders can be hung, making it convenient for workers to climb up for maintenance.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
