Self-drive type urban underground prefabricated comprehensive pipe rack paving hoisting machine and construction method

Abstract

The invention discloses a self-drive type urban underground prefabricated comprehensive pipe rack paving hoisting machine and a construction method. The hoisting machine comprises a truss and a drivemechanism arranged on the truss. A front guide device is arranged at the front end of the truss, and the front guide device and the truss are connected through a detachable pin shaft. Hydraulic cylinders are vertically arranged at the bottoms of stand columns at the four corners of the truss, and the bottom of the truss is provided with a support deviation correcting beam capable of being collected or released. A crane tackle is arranged on the top of the truss, a winch is arranged at the middle portion of the crane tackle, the winch is connected with pulley sets arranged at the two ends of the crane tackle and pulley sets arranged at the two ends of the truss through steel wire ropes, a hoisting beam is transversely and horizontally arranged on the top of the crane tackle and provided with a tensioning adjusting screw, and the bottom of the tensioning adjusting screw is connected with a hoisting cable for hoisting a prefabricated comprehensive pipe rack. According to the disclosed hoisting machine and the construction method, the construction cost can be reduced, the work efficiency is improved, potential safety hazards during construction are reduced, and the construction qualityis guaranteed.

Description

technical field [0001] The invention relates to an urban underground prefabricated comprehensive pipe gallery laying equipment, in particular to a self-propelled urban underground prefabricated comprehensive pipe gallery laying hoisting machine and a construction method. Background technique [0002] At present, many cities in my country have begun to promote the construction of underground comprehensive utility corridors to provide better and safer services for urban construction. Due to the late start of technology in our country, there are still various problems in the construction of underground pipe galleries, the most common of which is to move the pipe gallery horizontally. Due to the large volume of the pipe gallery during construction, it can be The pipe gallery is hoisted into the tunnel by a crane, but the pipe gallery needs to be moved horizontally to achieve the purpose of contacting the front section of the pipe gallery in order to connect with the front sectio...

AI Technical Summary

Problems solved by technology

[0003] Existing technologies use manual adjustments to ensure the position of the pipe gallery through cranes and artificial construction. This method is cumbersome to install and has a large span in the construction site. If the pipe gallery is moved in place, it will be time-consuming and labor-intensive, and the operating cost will be high. , and the position of the pipe gallery cannot be accurately guaranteed. At the same time, there are still potential safety hazards when the crane is hoisting and adjusting the position. The pipe galleries are easy to collide with each other and affect the construction quality.
