TECHNICAL FIELD

[0001] The application relates to the technical field of anchor withdrawal devices, in particular to an anchor cable rapid anchor withdrawal device for underground cavern construction support. BACKGROUND

[0002] In the field of underground cavern construction, anchor cables are an important part of the support structure, and their stability and reliability are directly related to the safety and stability of the cavern. However, when the cavern construction is completed or needs to be maintained, it is often necessary to withdraw part or all of the anchor cables. Anchor withdrawal operation, i.e. pulling out the anchor cable from the anchoring body, is a key link in underground cavern construction, and its efficiency and safety directly affect the progress of the project and the working conditions of the workers.

[0003] Due to the high position of part of the anchor cables, located on the ceiling, workers usually need to set up scaffolding or ladders to reach the height of the anchor withdrawal operation. This process is not only time-consuming and tedious, but also difficult to operate in the limited space underground, increasing the safety risk of construction. In addition, as the anchor withdrawal operation proceeds, workers need to frequently move the scaffolding or ladders when withdrawing anchor cables in different areas, which not only reduces work efficiency but also increases the labor intensity of workers. During the anchor withdrawal process, workers need to hold tools such as jacks for a long time, which not only leads to worker fatigue. CONTENT OF THE INVENTION
