Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary pipe laying devices, in particular to an auxiliary pipe laying device for underground buried pipes. Background Art

[0002] The existing buried pipe ground source heat pump system consists of a water source heat pump unit, a geothermal exchange system, and a system within the building. The entire buried pipe system is a permanent concealed project. Every link and every process must strictly control quality. The construction of the buried pipe should ensure that each process must be completed in place. During the underground pipe burial process, it is often necessary to use auxiliary pipe laying devices.

[0003] In the existing technology, the method of lowering a vertical pipe is to first measure the required length of the pipe body, and then manually carry the pipe body into the well. This is time-consuming and labor-intensive, and has a large error rate. Alternatively, the pipe is lowered using a device such as an electric hoist. Due to different pipe sizes and models, it is easy to fail to properly center and clamp the pipe during lowering, resulting in deviation after lowering. Or due to different pipe weights, the device may tip over during the lowering process. Therefore, it is necessary to improve an auxiliary pipe lowering device for underground pipes to solve the above problems. Utility Model Content
