Urban underground pipeline repairing device

Abstract

The invention belongs to the field of underground pipeline machining equipment, and particularly relates to an urban underground pipeline repairing device. The urban underground pipeline repairing device comprises a vehicle body, a cleaning mechanism is arranged on the vehicle body, a rotating part is rotatably connected to the other side of the vehicle body, a plurality of material spraying mechanisms and curing mechanisms which are evenly distributed are arranged on the rotating part, the multiple material spraying mechanisms and the curing mechanisms are distributed on the rotating part atintervals, the vehicle body moves in the pipeline through rolling wheel mechanisms, and the vehicle body is provided with a detection mechanism capable of detecting the pipeline. According to the urban underground pipeline repairing device, repairing glue can be continuously sprayed out of the material spraying mechanism in the rotating process of a rotating frame, the repairing glue can be evenlytrowelled in the pipeline through rollers, the repairing glue can be solidified in the rotating process of the rotating part, and therefore in the pipeline repairing process, the repairing glue can be overlapped layer by layer; and in this way, the drying efficiency and the drying effect of the repairing glue can be improved.

Description

technical field [0001] The invention belongs to the field of underground pipeline processing equipment, in particular to an urban underground pipeline repair device. Background technique [0002] Underground pipelines are pipelines laid underground to transport liquids, gases or loose solids. Underground pipelines are arranged below the ground, which can greatly reduce the occupied space of pipelines, and the setting of underground pipelines can also greatly reduce urban residents and pipelines. The influence between them leads to damage to the pipeline. At the same time, for the hot water pipeline, etc., the pipeline installed underground can also perform functions such as heat preservation, thereby reducing the heat volatilization during pipeline transportation. [0003] Although underground pipelines have many advantages, local corrosion and other phenomena will still occur in underground pipelines during long-term use, resulting in local damage to pipelines. For the main...

Problems solved by technology

[0003] Although underground pipelines have many advantages, local corrosion and other phenomena will still occur in underground pipelines during long-term use, resulting in local damage to pipelines. For the maintenance of underground pipelines, the most common way is to expose pipelines through excavation. In the outside world, the repair of the pipeline can be realized. However, in the current process of this method, operations such as excavation, repair and burial are required, and this section of the road will be prohibited from passing through during the operation, which will affect the normal life of residents, and the road surface will be damaged during the process. Repair, and the repair time in the whole process is longer, and the sunshade will lead to a much higher maintenance cost. In fact, only the damaged part of the pipeline needs to be repaired, and the rest of the pipeline does not need to be operated. Therefore, there is a need for pipeline repair. Internal repair, but the current internal repair of the pipeline has a poor repair effect. This is mainly due to the difficulty in controlling the amount of repair glue in the repair process. Liquid state, the repair glue is easy to fall off, or when there is less repair glue, the curing effect is better, but the thickness of the repair glue is too thin, the repair strength is weak, and the damaged pipe is easy to be damaged again.
