Multifunctional operation vehicle for self-propelled shield tunnel construction

Abstract

The invention provides a multifunctional operation vehicle for self-propelled shield tunnel construction. The operation vehicle comprises a walking mechanism, a gantry type support frame, a top operation platform, a left operation platform, a right operation platform, a lifting device and a hydraulic system, wherein the gantry type support frame comprises a left vertical support, a right verticalsupport and horizontal support, wheel bodies of a main driving wheel and a driven wheel of the walking mechanism are respectively connected with corresponding installation supports through a deflection mechanism and can realize deflection, each walking wheel is provided with a turning oil cylinder; the lifting device comprises an electric hoist, a walking track, an electric hoist walking mechanismand an electric cabinet; and the walking track is installed between the tops of the left and right vertical supports. According to the invention, the operation vehicle can walk on a tunnel segment directly and freely without affecting the horizontal construction and transportation of the shield, the operation platform can realize the full operation surface coverage of a tunnel section, and the operation vehicle can be used as a construction platform, hoisting equipment, a carrying platform and a transportation device, and has multiple purposes.

Description

technical field [0001] The invention relates to a shield construction operation vehicle, in particular to a multifunctional operation vehicle for self-propelled shield tunnel construction. Background technique [0002] With the development of domestic urban rail transit construction, shield construction technology has developed rapidly in our country. At present, tunnel construction mostly uses shield machines for excavation. Since the inner diameter of the shield is mostly larger than 5.5m, and the segment is in the form of a ring, many workstations cannot complete the work on the floor or on the walk during the excavation process of the shield. The advancement of the machine, the grouting of the segment installation will also cause water leakage, and the segment needs to be repaired and the secondary grouting work; when the shield tunnel is excavated, synchronous grouting is required, because synchronous grouting is accompanied by Indispensable quality defects such as lar...

AI Technical Summary

Problems solved by technology

[0004] In addition, the main function of the existing tunnel construction vehicles and work platforms is to build an aerial work platform, which is convenient for construction personnel to repair, clean and grout the segments in the middle and upper parts of the tunnel; , and will also be equipped with battery car walking tracks and other temporary supports erected through steel rails. When the shield exits, the removed steel rails, sleepers, and pipelines need to be hoisted and transported, as well as some daily materials and tools in the tunnel. Hoisting, It is necessary to set up additional hoisting equipment and set up hoisting brackets, which is troublesome

Moreover, during the shield construction process, there are also some construction equipment, such as double-liquid grouting pumps, washing machines, air compressors, jacks, mud and water collection devices, etc. These equipment need to set up temporary construction platforms during the construction process. The construction and dismantling of these platforms are relatively cumbersome, which will greatly increase the cost of manpower and material resources
