Shield machine segment assembly machine grabbing device

Abstract

The invention discloses a gripping device of a segment erector of a shield tunneling machine, relating to a gripping device used when the segment erector of the shield tunneling machine grips pipe segments. The gripping device is designed mainly for solving the problem that manual connection operation is required between a gripping part of a gripping device of a segment erector of an existing shield tunneling machine and pipe segments, and the pipe segments are easy to fall off. The gripping device disclosed by the invention comprises an arc-shaped bottom plate, wherein an upper adjusting oil cylinder, a lower adjusting oil cylinder and a ball seat are all fixed on the bottom plate; a locking seat is fixed on the bottom plate; an annular table of the locking seat is arranged in an annular slot of a locking guide rail; the locking guide rail surface of the locking guide rail is of a halved structure; a bulb at the bottom of a gripping arm is arranged in a hinge ball seat; a bulb gland is fixed with the hinge ball seat; the bulb gland is provided with a hole; cylinder bodies of an left adjusting oil cylinder, a right adjusting oil cylinder, a front adjusting oil cylinder and a rear adjusting oil cylinder are fixed on the gripping arm; cylinder rods of the left adjusting oil cylinder, the right adjusting oil cylinder, the front adjusting oil cylinder and the rear adjusting oil cylinder are all fixed on the bottom plate; a cylinder body of a locking oil cylinder is fixed on the bottom plate; Y-shaped guide rail surface connecting plates connected to the cylinder rods are respectively connected with the end parts of the locking guide rail surfaces of the two half surfaces. The gripping device disclosed by the invention has the advantages that the pipe segments can be automatically mounted and the pipe segments cannot fall off.

Description

Technical field: [0001] The invention relates to a grabbing device used when a segment assembly machine of a shield tunneling machine grabs segments. Background technique: [0002] When the existing grabbing device of the segment assembly machine of the shield machine is working, the grabbing place and the segment need to be manually connected, and the work efficiency is low; Only one degree of freedom is limited, and the segment is prone to deflection; and there is no locking device, the segment is easy to fall off from the grabbing device, causing danger. Invention content: [0003] The technical problem to be solved by the present invention is to provide a shield machine segment assembly that can automatically connect between the grabbing part and the segment, the segment will not deflect, and the segment will not fall off the grabbing device. Machine grabbing device. [0004] The above purpose is achieved in this way: it includes a curved base plate, the cylinder bod...
