Embodiment
[0039] like figure 1 , figure 2 and image 3 In the embodiment shown, a valve tower single-module maintenance tool includes a bracket 3, two bracket guide rails 4 installed in the bracket, a fork connection part 5, an adapter guide rail 8 and a migration mechanism, and the bracket can be a frame structure. , which can be a platform; the distance between the bracket guide rails corresponds to the guide rail of the module to be repaired 2, the module to be repaired has rollers at the bottom, the bracket guide rail is groove-shaped, and the bracket guide rail has a certain groove depth to ensure the module to be repaired. The set of rollers does not derail; the fork connection part is arranged at the bottom of the bracket, and the fork connection part includes two profiles with sockets and bolts. The shape of the sockets matches the fork teeth of the forklift, usually square, and the profiles are fixedly connected. At the bottom of the bracket, the bolts pass through the profi...

The invention discloses a valve tower single-module maintenance tool, which comprises a bracket, a bracket guide rail installed in the bracket, a fork tooth connecting part, a transfer guide rail and a migration mechanism. Correspondingly, the fork connection part and the transfer mechanism are respectively connected with the bracket, the fork connection part is arranged at the bottom of the bracket, the bracket is provided with a limiter for fixing the module to be repaired, and the transfer guide rail is installed to the valve tower frame corresponding to the guide rail of the module to be repaired , the bracket guide rail is docked with the guide rail of the module to be repaired through the transfer guide rail. In this scheme, by first connecting the transfer guide rail to the guide rail to be repaired, the side shift distance when installing the bracket guide rail is reduced, and the insufficient side shift amount of the fork teeth is avoided. The maintenance tool is connected with the fork teeth, which is simple and convenient, and the module disassembly efficiency is high.
Description
technical field [0001] The invention relates to the field of electric power construction, in particular to a valve tower single-module maintenance tool and a maintenance method. Background technique [0002] The DPFC system consists of 2 valve towers, each valve tower contains A, B, C three phases, the distance between the valve tower frame and the valve tower frame is 2300mm; the size of the single module is: 1439*1400*1200mm, and the weight exceeds 1t ; When a single module is repaired in the prior art, due to the limitation of the valve tower spacing, a crane is usually used, but the single module is easy to shake and cause damage during the disassembly process, and the efficiency is low. [0003] For example, a "Valve Tower Module Replacement Device and Valve Tower Module Replacement Method" disclosed in Chinese Patent Documents, the publication number of which is CN110240058B, includes: a valve tower module support and transfer unit, and a valve tower module suitable fo...
