Jacking mold trolley efficient and convenient to use

Abstract

The invention discloses a jacking mold trolley efficient and convenient to use, and relates to the technical field of lining trolleys. The jacking mold trolley efficient and convenient to use comprises a bottom frame, the bottom of the bottom frame is fixedly connected with fixed supporting legs, the top of the bottom frame is fixedly connected with supporting columns, the top ends of the supporting columns are fixedly connected with a top beam, a ladder stand is in sliding connection between the top beam and the front face of the bottom frame, sliding rails are welded to the front face of thebottom frame, rollers are fixedly connected to the bottom of the ladder stand, and the tops of the sliding rails are fixedly connected with sliding grooves matched with the rollers. According to thejacking mold trolley efficient and convenient to use, the ladder stand is slidingly arranged on the front face of the trolley, a worker can freely climb to the trolley from any position, use is convenient, the ladder stand is moved to the needed position, then, L-shaped plug pins are pulled down to be inserted into adjacent positioning pin holes, rapid fixing is achieved, the phenomenon that during worker climbing, the ladder stand is stressed to move, and the worker falls off is avoided, and use is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of lining trolleys, in particular to an efficient and convenient top form trolley. Background technique [0002] The tunnel lining trolley is special equipment that must be used in the secondary lining of the tunnel construction process, and is used for the concrete lining construction of the inner wall of the tunnel. Concrete lining trolley is an indispensable non-standard product for secondary lining in the tunnel construction process, mainly including simple lining trolley, fully hydraulic automatic walking lining trolley and grid lining trolley. Fully hydraulic lining trolley can be divided into side-top arch type, full-circle needle beam type, bottom mold needle-beam type, full-circle walking type, etc. In the construction of hydraulic tunnels and bridges, lifting slip form, jacking slip form and overturning form are also widely used. The full-circle lining trolley is often used in the construction of...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an efficient and convenient top mold trolley, which solves the problem that the existing lining trolley supports a section of the working face with cross braces, and then lining its inner wall. The surface quality of the lining will be affected due to the obstruction of the cross braces. After the cross braces are removed, the wall hole needs to be repaired later, which is troublesome. In addition, some existing trolleys are taller and longer, and ladders are set beside them for workers to go up and down. , when operating in different positions, it is troublesome for workers to go up and down the ladder at a fixed position, and it is troublesome to walk back and forth, and it is difficult to climb down quickly if there is a danger
