Repair and maintenance device

Abstract

The invention belongs to the technical field of pipeline auxiliary equipment, and discloses a repair and maintenance device. The repair and maintenance device comprises a moving mechanism, a wrapping mechanism and a spraying mechanism. The wrapping mechanism comprises a fixing assembly, a release roller and a collection roller. An annular sliding way is arranged in the fixing assembly and used for clamping a to-be-maintained workpiece, a protective film is wound around the release roller and the collection roller, and the release roller is rotationally arranged relative to the fixing assembly and used for releasing the protective film. The end of the collection roller is configured to penetrate through the annular sliding way and be in sliding fit with the annular sliding way so that the protective film can be wound around the outer portion of the to-be-maintained workpiece, and the collection roller is used for collecting the protective film. The release roller and the collection roller of the repair and maintenance device ensure that the protective film is stably conveyed, and the wrapping effect is good. The fixing assembly provides a repair and maintenance environment for the to-be-maintained workpiece, the protective film wraps the outer portion of the to-be-maintained workpiece along the annular sliding way arranged on the fixing assembly, the protective film is prevented from bubbling or wrinkling, and the repair effect is good.

Description

technical field [0001] The invention relates to the technical field of electric power pipeline auxiliary equipment, in particular to a repair and maintenance device. Background technique [0002] As an important part of urban underground space, power pipelines are laid with high-voltage cable lines of 10kv and above, which are responsible for important power transmission tasks, and power pipelines are long-distance transmission underground, and the condition of pipelines directly affects the entire transportation project. Therefore, the requirements for the safety and maintenance of power pipelines are becoming increasingly stringent. During the long-term use of the pipeline, external collisions or biological corrosion may easily cause cracks or damage to the pipeline itself, which needs to be repaired quickly. [0003] In the prior art, when quickly repairing the pipeline, first, clean the pipeline, place repair equipment around the pipeline, and clean the pipeline mechani...

AI Technical Summary

Problems solved by technology

During the construction process, the pipeline will be wrapped manually. Due to the difference in personal technology, the technical problems of the pipeline package may fall off or be damaged, and the time cost of pipeline maintenance will be greatly increased, consuming manpower and financial resources. The repair effect is not good

[0006] 2. Manually spray the repair agent on the repaired pipeline to enhance the corrosion resistance of the pipeline, but in the process of manual spraying, the sprayed layer is incoherent, and the spraying effect is not good

If a large gap is encountered, the thickness of the sprayed layer will be uneven, which will increase the project cost on the one hand, and put forward higher requirements on the construction technology on the other hand.

[0007] 3. The existing pipeline spraying repair device is large in size and complex in structure, and cannot be accommodated in a small space, so it is not suitable for all construction environments, and the use scenarios of the device are limited
