Description

Technical Field

[0001] The invention belongs to the technical field of shield construction, and particularly relates to a hanging rack for a tram battery in a shield and a using method thereof. Background Art

[0002] In the tunnel of shield construction of urban rail transit projects, there is generally a launch shaft, and the tram battery that can provide power is hoisted from the ground to the bottom of the shaft. At present, only one group of batteries can be hoisted at a time, and it takes ten minutes to hoist one group of batteries. However, a tram requires three groups of batteries, and each time the batteries are replaced, they need to be hoisted three times repeatedly. Hoisting three times takes thirty minutes. The more times the batteries are replaced, the more construction time is consumed. For a long and large tunnel, the consumed time is more obvious, thus affecting the progress of the construction tunnel. Summary of the Invention
