Shield machine segment moving and lifting device

Abstract

The invention discloses a segment moving and lifting device for a shield tunneling machine. The segment moving and lifting device for the shield tunneling machine comprises a pair of horizontal traveling mechanisms and a pair of lifting mechanisms. Each horizontal traveling mechanism comprises a first hydraulic reel, a second hydraulic reel and a moving pulley set. Each lifting mechanism comprises a third pulley body support, a fourth pulley and a fifth pulley, wherein the fourth pulley and the fifth pulley are fixed to the third pulley body support. In addition, steel wire ropes are arranged. The middle of each steel wire rope winds around a first pulley, the corresponding fourth pulley, a third pulley, the corresponding fifth pulley and a second pulley, and the two ends of each steel wire rope are fixedly wound on the corresponding first hydraulic reel and the corresponding second hydraulic reel separately. According to the segment moving and lifting device for the shield tunneling machine, the horizontal traveling mechanisms and the lifting mechanisms are formed by the hydraulic reels, the moving pulley sets and the upper and lower pulleys correspondingly, and the structural design is concise and ingenious; conveying in the horizontal direction and lifting conveying in the vertical direction are achieved through organic combination of the pulley sets, neither electric driving nor braking with brakes is needed, environment requirements are lowered, the service life is long, and equipment cost and maintenance cost are reduced.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a segment moving and lifting device of the shield machine. Background technique [0002] The segment transportation and hoisting from the shield machine feeder to the assembly machine below the segment is in charge of the segment crane located on the double-track beam of the bridge frame. The current segment crane is generally composed of two parts. The first part is the traveling mechanism composed of the motor and the reducer, which is responsible for the horizontal transportation of the segment; the second part is composed of the motor, reducer, brake device and chain reel. The lifting mechanism is responsible for the vertical transportation of the segments. However, the circuits of motors, reducers and other devices are easily affected by harsh environments such as humidity and dripping water during tunnel construction. Braking devices are frequently damaged and main...
