Separated vacuum chuck grasp device on duct piece assembling machine

Abstract

The invention relates to a separate vacuum sucker grasping device on assembling machine for duct piece, characterized in that the whole vacuum sucker in prior technology is divided into one middle vacuum sucker and two side vacuum suckers. The middle vacuum sucker is installed with the inner arc face near the short duct piece in the middle of short duct piece and side vacuum suckers are hinged with two ends of middle vacuum sucker. Two side vacuum suckers are mated with the inner arc face of long duct piece. Rubber patch is boned at one side of middle and side vacuum suckers contacted with long and short duct piece. Cylinder support is connected with the other side of middle vacuum sucker at the middle position and two cylinder supports are hinged with one end of hydraulic cylinder. Ends of pistons of two cylinders are hinged with the connecting mechanism between the frame and side vacuum sucker. The invention is not only provided with reasonable structure but also applied in TBM assembling machine for duct piece and vacuum sucker grasping of assembling machine in shield machine. It is also provided with saving labor, safe operation, convenience and rapid usage and so on.

Description

technical field [0001] The invention belongs to mechanical equipment for tunnel construction, and relates to a vacuum sucker grip of a segment assembly machine suitable for hard rock layer—TBM tunnel construction, and a vacuum suction cup grip of a segment assembly machine suitable for soft soil layer—shield machine tunnel construction A split-type vacuum suction cup gripping device on a segment assembly machine. Background technique [0002] At present, the tunnel boring machines used in tunnel construction are roughly divided into two types, one of which is suitable for hard rock stratum—— TBM construction tunnel boring machine, the tunnel segment of each ring adopts equal division, that is, adopts or consists of 4 or 6 long segments of equal length are spliced ​​together. When splicing and combining, a segment assembly machine must be used. In order to make the long segments spliced ​​firmly and tightly, an integral vacuum suction cup is installed on the segment assembly ...

AI Technical Summary

Problems solved by technology

[0003] 1. It is laborious, time-consuming, inconvenient to operate and unsafe to use the mechanical method of manually driving the screw jacking device to grasp the segment

[0004] 2. The integral vacuum suction cup gripping device used on the tunnel segment splicing machine constructed by TBM can also meet the gripping requirements of the segments. Segment gripping requirements, and there will be a state of big bulls pulling small carts, so mechanical methods have to be used to grip short segments, resulting in the fact that the overall vacuum suction cup gripping device cannot be used on the tunnel segment splicing machine for TBM construction.
