Example Embodiment

[0015] Figure 1 is a specific embodiment of the present invention. It is a split vacuum suction cup gripping device installed on a shield machine segment assembly machine. Figure 1 shows the working state of the piston rod of its hydraulic cylinder 3 after retracting, that is, The medium vacuum suction cup 4 is pressed tightly on the surface of the short tube sheet 13. Its structure includes a base 12, which is characterized by: a side vacuum suction cup 1, a medium vacuum suction cup 4, a suction cup connecting seat 2, a hydraulic cylinder 3, and a cylinder support 5. The rubber gasket 6, the long tube piece 11, and the short tube piece 13 are composed of the integrated vacuum sucker in the prior art divided into a medium vacuum sucker 4, the left and right vacuum suckers 1, and the short tube piece 13 made of concrete In the center position, close to the inner arc surface of the short tube piece 13, a medium vacuum chuck 4 made of steel plate is installed to fit the two ends of ...

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 ...
