Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to a shield belt machine lifting and adjusting frame. Background Art

[0002] At present, with the acceleration of the national infrastructure construction process, shield tunneling machines have been widely used in the construction of subway, railway, highway, municipal, hydropower and other tunnel projects. Conventional shield tunneling machines are mainly divided into mud balance type, earth pressure balance type and hard rock tunneling machines according to different working methods. Among them, after the cutterheads of the earth pressure balance shield machine and the hard rock tunneling machine cut and crush the soil and rock, the belt conveyor on the subsequent supporting trolley continuously transports the slag from the inside of the whole machine to the outside, thereby realizing the continuous forward excavation of the shield machine. As the main component for transporting the slag inside the shield machine to the outside, whether the belt conveyor installed on the trolley at the rear of the main machine is stable in operation is related to the efficiency of the entire shield tunneling construction.

[0003] During the construction process, due to the influence of various factors, the shield construction axis usually changes dynamically in the horizontal and vertical directions. When the axis changes greatly, the conveyor belt on the belt conveyor will deviate during operation, causing abnormal soil transmission, uneven force, reduced roller life, and abnormal wear on the offset side of the conveyor belt and the bracket, affecting the service life. Utility Model Content

[0004] The purpose of the utility model is to provide a shield belt conveyor lifting and adjusting frame, which can adjust the inclination on both sides of the belt conveyor axis direction during shield construction to adapt to the changes caused by the deflection of the tunnel axis and solve the problems of the above-mentioned shield belt conveyor in operation.
