Multifunctional fabricated hydraulic drive moveable trestle

Abstract

The invention provides a multifunctional fabricated hydraulic drive moveable trestle, relating to a hydraulic drive moveable trestle used for various excavation constructions carried out by various tunnel or cavity drilling and blasting methods. The trestle comprises a main trestle and approach trestles positioned on both ends of the main trestle, wherein, the main trestle comprises a transverse beam and trusses connected to both sides of the transverse beam, the upper and the lower ends of the trusses are respectively provided with upper chord members of the main trestle and lower chord members of the main trestle. The invention has the technical scheme that a steering wheel is installed on the front end of the main trestle, a driving wheel and a rear supporting device are installed on the rear end of the main trestle, and lifting mechanisms are arranged on the steering wheel and the driving wheel. Moveable tracks are installed on the lower chord members of the main trestle between the steering wheel and the rear supporting device; concrete slicking devices, fixing devices for inverted arch templates, front supporting devices and lengthwise moved idler pulleys for front support are installed on the moveable tracks, and drawing mechanisms are installed on the lower chord members of the main trestle on the left and the right sides of the trestle. The trestle is suitable for various excavation constructions of public roads, railroads, water diversion, flood discharge, anti-aircraft defense, and the like by the tunnel or cave drilling and blasting methods, and meets the requirements of simultaneous construction, namely the tunnel or cave excavation and the pouring of concrete for the bottom inverted arch.

Description

technical field [0001] The utility model relates to a multifunctional assembled hydraulically driven mobile trestle, which relates to a hydraulically driven mobile trestle used for excavation construction of various tunnels such as roads, railways, water diversion, flood discharge and air defense, or tunnel drilling and blasting. Background technique [0002] Tunnel or tunnel drilling and blasting excavation and concrete bottom arch lining often interfere or conflict with each other during construction, which will inevitably affect the entire project cycle and quality. At present, various simple construction trestles commonly used at home and abroad can only play the role of a transition springboard from the initial support surface to the inner lining arch, and cannot solve the problem of tunnel or tunnel drilling and blasting in parallel with the concrete bottom arch lining. Construction problems will cause great safety hazards, that is, it is difficult to ensure the safety...

[0002] Tunnel or tunnel drilling and blasting excavation and concrete bottom arch lining often interfere or conflict with each other during construction, which will inevitably affect the entire project cycle and quality

At present, various simple construction trestles commonly used at home and abroad can only play the role of a transition springboard from the initial support surface to the inner lining arch, and cannot solve the problem of tunnel or tunnel drilling and blasting in parallel with the concrete bottom arch lining. Construction problems will cause great safety hazards, that is, it is difficult to ensure the safety of tunnel or tunnel construction equipment (such as excavators, loaders, concrete pump trucks, steel bar transport vehicles and slag trucks, etc.) It is difficult to move and cannot meet the needs of slag discharge transportation and concrete lining construction at the same time, so the construction efficiency is low and the cost is high
