Description

Technical Field

[0001] This invention relates to the field of circuit breaker arc-extinguishing chamber mobility technology, and more particularly to a mobility device for circuit breaker arc-extinguishing chambers. Background Technology

[0002] Current technologies face numerous challenges in the relocation of 500kV circuit breaker arc-extinguishing chambers. Firstly, the operation is complex, requiring the use of cranes to dismantle equipment such as disconnect switches and current transformers on both sides of the arc-extinguishing chamber. Furthermore, a large amount of sulfur hexafluoride gas must be recovered from the chamber before dismantling, and the construction period for a single bay often reaches approximately 15 days. Secondly, the use of cranes necessitates the shutdown of the 500kV busbar, adjacent lines, and main transformer bays, resulting in a power outage throughout the hoisting process, making it difficult to control both grid and operational risks.

[0003] In addition, due to the lack of specialized tools, ordinary hoisting methods can easily cause the arc-extinguishing chamber to tilt or roll during hoisting. This not only requires workers to have high binding skills, but also poses a risk of falling, seriously affecting operational safety and efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a mobile device for the arc-extinguishing chamber of a circuit breaker, which can adjust the width and distance between the two sets of slide rail assemblies supporting the arc-extinguishing chamber tank and the support height according to actual use requirements; the structure is simple, the support strength is large and the portability is high.

Each set of support components 1 includes: two support legs 11a and 11b arranged opposite each other and a detachable crossbeam 12 connected between the two support legs 11a and 11b. The two support legs 11a and 11b share the same set of slide rail components 2. Each support leg 11a and 11b includes: an outer support leg 111, an inner support leg 112 sleeved in the outer support leg 111, a roller 113 mounted on the inner support leg 112, and a support block 114 mounted on one end of the outer support leg 111.

[0023] The outer support leg 111 includes: a support leg body 1111, a first mounting end 1112 extending from one side of the support leg body 1111, and a second mounting end 1113 extending from the other side of the support leg body 1111; the two support legs 11a and 11b on the same set of slide rail assemblies 2 are respectively connected to the crossbeam 12 through the two first mounting ends 1112; the support leg body 1111 is provided with a plurality of first mounting holes 1111a, which are multi-level through pin holes; the inner support leg 112 is provided with a second mounting hole.

[0024] Wherein: Bolt A passes through any of the first mounting holes 1111a and is fastened to the second mounting hole, fastening the outer support leg 111 and the inner support leg 112 together, so as to adjust the height of the support assembly and realize the function of height adjustment; the second mounting ends 1113 of the support legs of the two opposing slide rail assemblies are respectively provided with a first plate 1113x and a second plate 1113y, and the support legs of the two opposing slide rail assemblies are fixed by the overlap between the first plate 1113x and the second plate 1113y.

[0025] The first plate 1113x and the second plate 1113y are respectively provided with multiple third mounting holes r, and the multiple third mounting holes z are multi-level through holes; the bolts B pass through the third mounting holes r on the first plate 1113x and the second plate 1113y of the two adjacent sets of slide rail assemblies to fasten the two adjacent sets of slide rail assemblies together; the first plate 1113x and the second plate 1113y adopt a staggered overlapping structure, and the third mounting holes r on the first plate 1113x or the second plate 1113y are waist-shaped holes, which are used to adjust and change the width distance between the two sets of slide rail assemblies to realize the function of changing the width.

[0026] In practice, the outer support leg 111 and the inner support leg 112 are hollow columnar structures, and the outer support leg 111 and the inner support leg 112 are respectively formed by welding four metal plates that surround each other.

[0027] The support block 114 is triangular in shape and has an arc surface on one side. Its function is to support the arc-extinguishing chamber tank O through multiple support blocks 114.

[0028] Preferably, the support block 114 is provided with an anti-slip rubber pad 114t to fit tightly against the bottom of the arc extinguishing chamber. Furthermore, the bottom of the support block 114 is provided with an assembly cavity M. The first horizontal bolt C passes through the outer support leg and is fastened to the assembly cavity M. The second horizontal bolt D passes through the support block 114 and is fastened to the outer support leg inserted into the assembly cavity. Changing the screw-in position of the first horizontal bolt C and the second horizontal bolt D is used to adjust the relative position of the support block 114 with respect to the outer support leg 111.

[0029] During implementation, the support block 114 is fixed by the first horizontal bolt C. However, after tightening the first horizontal bolt C, the support block 114 is not completely clamped. The end of the first horizontal bolt C is square, and after tightening the first horizontal bolt C, there is a 1-2mm gap between the square end of the first horizontal bolt C and the side of the support block 114. That is, after tightening the first horizontal bolt C, the support block 114 can still move. Therefore, the movement of the support block 114 is stabilized by rotating and adjusting the second horizontal bolt D.

[0030] Furthermore, the first plate 1113x and the second plate 1113y adopt a staggered overlapping structure. The third mounting hole r on the first plate 1113x or the second plate 1113y is an oblong hole, used to adjust and change the width distance between the two sets of slide rail components, thereby achieving the function of changing the width. In implementation, the first plate 1113x and the second plate 1113y are stacked one on top of the other and fixed by four bolts; that is, the overlap size of the first plate 1113x and the second plate 1113y is set to be adjustable, and the four screws pass through the first plate 1113x and the second plate 1113y respectively for fastening.

[0031] Preferably, anti-slip serrations are provided between the first plate 1113x and the second plate 1113y. In practice, the adjustment range of the two plates is 50-100mm, which can be adapted to arc-extinguishing chamber tanks of different diameters or support structures with different spacing. In practice, bolt A passes through any of the first mounting holes 1111a and is fastened to the second mounting hole, thus connecting the outer support leg 111 and the inner support leg 112 to adjust the height of the support assembly and achieve height adjustment. In this embodiment, the height adjustment of the multi-stage through-holes in the first mounting hole 1111a can achieve a height adjustment of 50-100mm to meet the height requirements of different working scenarios. Furthermore, the slide rail assembly 2 includes: a first channel steel 21 and a second channel steel 22 connected to the first channel steel 21. The first channel steel 21 and the second channel steel 22 are respectively provided with locking blocks 23, horizontal pins, and vertical pins.

Specifically: the horizontal pins are inserted laterally into the horizontal circular holes of the locking blocks 23 at the ends of the channel steels 21 and 22 to lock the vertical movement of the channel steels 21 and 22; the gate-shaped vertical pins are inserted into the vertical circular holes of the locking blocks 23 at the ends of the channel steels 21 and 22 to lock the left and right movement of the channel steels 21 and 22.

[0032] The first channel steel 21 and the second channel steel 22 are symmetrical in shape, and the roller 113 is fitted into the two channel steels 21 and 22. In this embodiment, the roller 113 is a high-strength roller. The purpose of setting the roller 113 and the slide assembly 2 is to facilitate movement without damaging the load-bearing ground. The whole assembly is made of high-strength alloy material, and the weight is controlled within 150kg, taking into account both structural strength and portability.

[0033] In a specific implementation of the movable device for the arc-extinguishing chamber of a circuit breaker in this embodiment of the invention, the first plate 1113x and the second plate 1113y are stacked vertically, with the overlap dimension of the first plate 1113x and the second plate 1113y being adjustable. Four screws pass through the first plate 1113x and the second plate 1113y respectively for fastening, thereby adjusting the width distance between the two sets of slide rail assemblies to achieve the function of changing the width. Bolt A passes through any of the first mounting holes 1111a and is fastened to the second mounting hole, fastening the outer support leg 111 and the inner support leg 112 together to adjust the height dimension of the support assembly, thereby achieving the function of height adjustment.

[0034] The mobile device for a circuit breaker arc-extinguishing chamber according to the present invention has the following advantages: Bolts pass through any of the first mounting holes and are fastened to the second mounting holes, securely connecting the outer and inner support legs to adjust the height of the support assembly; the second mounting ends of the support legs of the two opposing slide assemblies are respectively provided with a first plate and a second plate, and the support legs of the two opposing slide assemblies are fixed to adjacent slide assemblies by overlapping between the first and second plates.
