Full-hydraulic crawler-type self-moving trestle

Abstract

A full-hydraulic crawler-type self-moving trestle comprises a main trestle body, a front end trestle approach, a pier, a rear end trestle approach, a hydraulic pump station, a trestle approach hydraulic oil cylinder and a hydraulic control system. The two ends of the main trestle body are each provided with a main lifting hydraulic oil cylinder, and a crawler-type walking device is arranged on the lower portions of the main lifting hydraulic oil cylinders, and a walking steering hydraulic oil cylinder is arranged on one side of the crawler-type walking device; and the other end of the walking steering hydraulic oil cylinder is fixed to the pier. The full-hydraulic control is adopted, automation degree is high, and operation is convenient and reliable; conversion between transverse moving and longitudinal moving is rapidly achieved through a walking steering system; investment of manpower and other auxiliary machines is small; labor intensity of a worker is reduced; the working efficiency is improved; truss type guardrails are designed on the two sides of the trestle; and safety of a vehicle in the passing process is ensured.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and relates to a fast-moving full-hydraulic crawler-type self-propelled trestle for heavy vehicles to pass through during tunnel inverted arch construction. Background technique [0002] During tunnel inverted arch construction, due to the excavation at the bottom of the inverted arch, it will have a great impact on the slag discharge and feeding of large construction machinery and vehicles passing through the tunnel, especially when the tunnel construction period is relatively tight. for highlighting. The existing domestic tunnel construction mainly adopts the following two methods to solve this problem: first, springboard-type simple trestle; The above two trestles have the following defects in actual use: [0003] 1. There is no safety protection on both sides of the simple trestle, which is very prone to safety accidents such as vehicle overturning and falling; [000...

AI Technical Summary

Problems solved by technology

[0003] 1. There is no safety protection on both sides of the simple trestle, which is very prone to safety accidents such as vehicle overturning and falling;

[0004] 2. The simple trestle needs to be moved with the help of large construction equipment, such as loaders, excavators, etc.;

[0005] 3. When the rail-type inverted arch trestle is moved, the steel rails need to be placed manually. The operation is time-consuming and laborious, the work efficiency is low, and the work intensity of the personnel is high.
