Description

Technical Field

[0001] The utility model belongs to the technical field of crawler maintenance platforms, and in particular relates to a quick fixing device for repairing crawler tracks of a tunnel boring machine. Background Art

[0002] The crawler of a tunnel boring machine is one of the important components of a crawler tunnel boring machine. The crawler has a large ground contact area, good passability, strong adaptability, can walk with loads, and is suitable for hoisting operations on construction sites. However, the crawler of a tunnel boring machine plays a walking role during the movement of the tunnel boring machine and is often easily damaged. It needs to be removed regularly for maintenance. The conventional maintenance method is to remove the crawler of the tunnel boring machine and place it on a crawler maintenance table for inspection and maintenance. For example, the existing patent discloses "a quick fixing device for repairing the crawler of a tunnel boring machine, comprising a base and a support table, wherein the left and right ends of the base are connected to the flap by brackets, and the front end of the flap is provided with fixing bolts, and the lower end of the flap is provided with a movable table, and the interior of the movable table is connected to the pressure roller by a motor". It can be seen that what is described in the application is a common quick fixing device for repairing the crawler of a tunnel boring machine, that is, a crawler maintenance table. Two clamping and fixing structures are provided on the crawler maintenance table, which can clamp the crawler to facilitate subsequent inspection and maintenance.

[0003] In actual use, the quick fixing device for repairing the crawler track of a tunnel boring machine in the prior art uses two clamping screws to clamp and fix the crawler track. However, each time the crawler track is taken or placed, the clamping screws need to be rotated to the highest position due to the obstruction of the clamping screws in order to facilitate the removal of the crawler track, which reduces the flexibility and convenience of the entire device. There are disadvantages, and the existing maintenance platform does not have a rotation function, which makes it inconvenient to inspect the other side of the crawler track. Therefore, the present utility model needs to improve and optimize the existing quick fixing device for repairing the crawler track of a tunnel boring machine. Utility Model Content

[0004] The purpose of the utility model is to provide a quick fixing device for repairing a tunnel boring machine crawler, so as to solve the problems raised in the above background technology.
