Abstract

The invention provides a high-precision duct piece clamping and positioning mechanism of a ring type duct piece erector, and relates to the technical field of tunnel construction devices. The high-precision duct piece clamping and positioning mechanism of the ring type duct piece erector comprises a base, a connecting seat is fixedly connected to the middle of the top end of the base, a mounting plate is rotatably connected to the top of the connecting seat, a second motor is fixedly connected to one side of the top of the base, and a pinion is fixedly connected to the outer side of a shaft rod. The outer side of the small gear is connected with a gear ring in an engaged mode, and the middle of the gear ring is fixedly connected with a connecting cylinder. The moving block can move on the sliding rod in a reciprocating mode, the adapter base, the connecting column and the second rotating plate can drive the bearing plate to conduct vertical angle adjustment, accurate control over the angle position can be achieved through the first motor and the second motor, compared with an air cylinder and an oil cylinder, the control precision is higher, the installation deviation of duct pieces can be reduced, and the engineering quality is improved; the project progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of tunnel construction devices, in particular to a high-precision segment clamping and positioning mechanism of a ring-type segment assembly machine. Background technique [0002] At present, the assembly of ring segments generally starts from the standard block at the bottom of the tunnel, the adjacent blocks are installed in sequence, and the capping block is finally installed. For each piece of segment installed, immediately insert the connecting bolts of the longitudinal ring of the segment into the connection, and put on the nut and tighten it with an electric wrench. When capping and quick installation, first radially overlap 2 / 3 of the segment width, and then push longitudinally. After the segment is installed in place, extend the propulsion oil cylinder at the corresponding position in time to tighten the segment, and then remove the segment assembly machine. Strictly control the verticality and ro...
