A positioning device for a segment demoulding device

Abstract

A positioning device of a segment demoulding device, which is arranged on the panel of a vacuum suction cup, includes a motor, a worm, a rotating support component, a positioning head, a positioning rubber sleeve, a fixing head, a fixing screw, a control device and a light sensor, wherein the positioning The head includes a flange in the middle and a cylindrical structure set on both sides of the flange. The cylindrical structure on one side is fitted into the rotating support component, and the outer side of the cylindrical structure on the other side is fitted with a fixed head and a fixed screw to fit the positioning rubber sleeve. , the light sensor will sense the bright-dark-bright process during each drawing process, and the control device detects the end of the drawing process through the light sensor, the control device controls the motor to rotate, and drives the positioning rubber sleeve to rotate at a fixed angle, The positioning device can change the force-bearing position of the positioning sleeve on the positioning head according to the number of times of use, and can regularly remind the replacement of the positioning sleeve that has reached the end of its service life.

Description

technical field [0001] The invention relates to a shield segment stripping device, in particular to a positioning device for the segment stripping device. Background technique [0002] As the shield machine excavates, the segment assembly machine at the end of the shield machine continuously installs concrete segments on the side wall of the tunnel. Therefore, the quality of concrete segments affects the safety and service life of tunnel construction and use. In the production process of the segment, the steel mesh with fixed shape is first put into the segment steel mold, the concrete is poured after the mold is closed, and the mold is opened after steam curing. When demoulding the segment, a vacuum suction cup machine is usually used. The vacuum suction cup moves above the segment by driving, and provides a pulling force on the outer arc of the segment through the vacuum suction cup to complete the demoulding of the segment. [0003] Before hoisting the segment, the vacu...

Problems solved by technology

[0004] However, in the actual production process, since the position of the positioning head of the vacuum grabbing mechanism is fixed, the position of the positioning sleeve sandwiched between the positioning head and the segment is fixed each time the lateral force is applied, and the state of repeated extrusion at the same position The bottom is easy to be damaged, and if the positioning sleeve is damaged and is not replaced in time, it is easy to cause damage to the positioning hole of the segment during docking, or the gap between the positioning head and the positioning hole is too large, causing the segment to slip and fall off during the hoisting process
