Problems solved by technology

[0003] Tunnel construction generally uses trolleys to hoist prefabricated parts to assemble prefabricated parts. Due to the limitation of tunnel space, the range of movement of hoisting trolleys in the tunnel is blocked, and the volume and weight of prefabricated parts are relatively large. The installation can only be done successfully with greater physical strength of the personnel, which has problems such as low installation efficiency and long time occupation

Abstract

The invention provides a steering hoisting mechanism applied to a tunnel preform assembly trolley. The mechanism is mounted on a top frame of the assembly trolley, and comprises travelling rails, a travelling assembly, a rotating assembly, a lifting assembly and a controller. Under action of the controller, an electric hoist of the lifting assembly lifts preform and a travelling motor drives a travelling wheel group for enabling a travelling platform to slide on the travelling rails, so that a hoisting mechanism moves the preform; if the preform is rotated in direction, a rotating motor drivesa rotating shaft for enabling a rotating platform to rotate; and an electric hoist mounted on the rotating platform drives the preform to rotate, so that assembly angle requirements of the preform are met, and therefore, tunnel construction requirements of the preform are accomplished, mechanical automatic operation is realized, and working efficiency is improved.

Description

[0001] technical field [0002] The invention relates to the technical field of tunnel construction equipment, in particular to a steering and hoisting mechanism applied to a trolley for assembling tunnel prefabricated parts. Background technique [0003] Tunnel construction generally uses trolleys to hoist prefabricated parts to assemble prefabricated parts. Due to the limitation of tunnel space, the range of movement of hoisting trolleys in the tunnel is blocked, and the volume and weight of prefabricated parts are relatively large. The successful installation can only be done with great physical strength of the personnel, which has problems such as low installation efficiency and long occupation time. [0004] Therefore, how to provide a high-efficiency and automatic steering and hoisting mechanism applied to the tunnel prefabricated assembly trolley is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] In view of this, the pre...
