Description

Technical Field

[0001] This utility model relates to the field of idler replacement technology, and in particular to a TBM continuous belt top support idler replacement device. Background Technology

[0002] In TBM tunnel construction, the stable operation of the continuous belt conveyor system is crucial. Existing idler replacement devices have some shortcomings in practical applications. During the jacking process, scattered materials easily accumulate at the contact interface between the support frame and the belt. These accumulations form localized protrusions, disrupting the flatness of the support surface and causing uneven friction distribution on the belt during operation. This change in stress state interferes with the normal operating trajectory of the belt, inducing belt deviation. Once belt deviation occurs, it affects construction efficiency and equipment safety. Therefore, this application proposes a TBM continuous belt jacking idler replacement device. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where, during the jacking process, scattered materials easily accumulate at the contact interface between the support frame and the belt, causing local bulges and leading to belt misalignment.

[0006] Optionally, the top support assembly includes a jack, which is disposed below the second support frame. Above the jack, there is a base, a first support frame, and two support beams. The base is fixedly connected to the output end of the jack, and the two support beams are disposed between the base and the first support frame to form an H-shaped support structure.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] This application uses a motor to drive the connecting rod to rotate.
