Tube segment shipping and trolley towing integrated device of shield machine

Abstract

The invention relates to a tube segment shipping and trolley towing integrated device of a shield machine, belonging to the technical field of tunneling equipment. The integrated device comprises a two-track beam, a pair of electric hoists mounted under the two-track beam, a travelling trolley towing the electric hoists to travel and a connecting frame; the connecting frame is mounted on the two-track beam; the two-track beam is mounted between a traveling beam of a tube segment assembling machine and a first-section trolley of a back affiliated system; the front-station working end and the back-station working end of the two-track beam are horizontal beams, and a middle part of the two-track beam is an tilted beam; the front end of the two-track beam is lower than the back end of the two-track beam; the connecting frame is a truss structure; the left side and the right side of the connecting frame are respectively connected with the two beams of the two-track beam; the front end of the connecting frame is movably connected with the traveling beam of the tube segment assembling machine; and the back end of the connecting frame is connected with the first-section trolley of the back affiliated system through a pin shaft. The tube segment shipping and trolley towing integrated device of the shield machine provided by the invention has a simple structure, the bearing strength is enhanced under the premise of not increasing the weight, the shipping efficiency is high, the labor intensity for workers is lowered, and the cost and the failure rate of equipment are lowered.

Description

technical field [0001] The invention relates to tunnel excavating equipment, in particular to an integrated device for segment hoisting and trolley traction of a shield machine. Background technique [0002] The shield machine is a technology-intensive major engineering equipment that integrates mechanical, electrical, hydraulic, laser, sensing, measurement, control, information, computer and other technologies and is dedicated to the construction of underground tunnels. It has the functions of excavating and cutting soil, Functions such as muck transportation, tunnel lining assembly, measurement guidance and deviation correction, etc., are widely used in engineering fields such as subways, railways, highways, municipalities, and hydropower tunnels. Segment conveying is an important link to ensure the assembly of tunnel lining. This link requires the device to be able to transport the segment from the segment trolley located at the first supporting trolley to the place wher...

AI Technical Summary

Problems solved by technology

Since the lifting device adopts a two-section double-beam structure to transport the segment, after the segment 5' is transported on the main double-track beam 1', it needs to be unloaded from the electric hoist 3' of the beam and then installed on the auxiliary double-track beam 2' On the two electric hoists 3', and then lift, so the transportation efficiency is obviously reduced, and the labor intensity of the staff is increased

At the same time, the cost of two pairs of electric hoists 3' is also very high, and the failure rate of the equipment will also increase
