Non-excavation pipeline renewal device capable of easily adjusting forming pipe diameters

Abstract

The invention relates to a non-excavation pipeline renewal device capable of easily adjusting forming pipe diameters. The on-excavation pipeline renewal device comprises a roller chain ring and a driving assembly; the roller chain ring is composed of a plurality of chain roller units; each chain roller unit is mainly composed of a chain roller, chain links and a chain link adjusting rack, every two chain links are symmetrically installed on the two radial sides of the corresponding chain roller in a hinged mode, and each chain link adjusting rack is installed on the lower portions of the two corresponding chain links in a hinged mode; the chain roller unit at the initial end of the roller chain ring and the chain roller unit at the tail end of the roller chain are staggered at a certain angle; the driving assembly is installed on the initial chain roller, and the driving assembly comprises a hydraulic motor, a decelerating mechanism and a wheel pressing unit; one chain link of the chain roller unit is fixedly installed on one side of the decelerating mechanism, the wheel pressing unit is installed on the upper portion of the decelerating mechanism, and the hydraulic motor is installed on the other side of the decelerating mechanism; and the hydraulic motor drives the wheel pressing unit to operate through the decelerating mechanism. According to the non-excavation pipeline renewal device capable of easily adjusting the forming pipe diameters, long-distance repair can be conducted for pipeline on the condition of non-excavation, and meanwhile, the device can be conveniently adjusted according to a need to adapt to different culverts with different diameters.

Description

technical field [0001] The invention belongs to pipeline updating and repairing equipment, in particular to a non-excavation pipeline updating equipment which is easy to adjust the formed pipe diameter. Background technique [0002] Urban drainage pipes are called the "underground lifeline" of the city, which shoulders the important task of urban sewage and waterlogging. As the scale of urban construction in my country continues to expand, more and more attention has been paid to the maintenance and repair of drainage pipes. The traditional method of pipeline repair is to use excavation to replace new pipelines, which results in a huge amount of work and high cost, and the project cannot be completed in a short period of time, which will lead to traffic jams, environmental pollution, etc., which are unbearable for modern urban construction. of. [0003] Trenchless repair technology is an engineering technology that uses trenchless or micro-excavation technology to partiall...

AI Technical Summary

Problems solved by technology

However, the structure of the existing winding device is complex, and the new pipe formed by winding is determined by the size of the equipment itself. One piece of equipment can only complete the winding and forming of pipes of one size.

Therefore, it is not possible to adjust the winding equipment for different diameter pipes or culverts during construction

If a single device is used, a large inner diameter needs to be sacrificed, and if multiple devices are used, there is a problem of high cost
