Tunnel steel formwork lining trolley convenient to center

Abstract

The invention belongs to the field of building construction machinery, and particularly relates to a tunnel steel formwork lining trolley convenient to center. A driving motor is fixedly arranged on the top of a base, and a transmission pipe is in transmission connection with an output shaft of the driving motor; the top end of a connecting shaft extends into the transmission pipe and is movably clamped with the inner wall of the transmission pipe; a supporting plate is glidingly connected with the top of the base; the transmission pipe is in movable transmission connection with the supportingplate; an output shaft of a lifting motor arranged at one side of the top of the base is in transmission connection with the transmission pipe; supporting rods are glidingly connected onto position limiting plates symmetrically and fixedly arranged on the top of the supporting plate; an arc-shaped edge beam is fixedly arranged on the top of each supporting rod; an adjusting motor positioned between the two position limiting plates is fixedly arranged on the top of the supporting plate; and an output shaft of the adjusting motor is respectively in transmission connection with the two supporting rods. The tunnel steel formwork lining trolley convenient to center has the advantages that in the use process, the position does not need to be adjusted for many times; in addition, the position and height of the arc-shaped edge beams can be adjusted again; and the lining at the designated position can be supported, and good convenience is achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction machinery and relates to a tunnel steel formwork lining trolley which is convenient for centering. Background technique [0002] With the development of society, we have more and more railway constructions, and more and more tunnels need to be built for railway construction. In tunnel construction, we need to use a lining method to construct tunnels. Lining refers to In order to prevent the surrounding rock from deforming or collapsing, a permanent support structure is built with reinforced concrete and other materials along the periphery of the tunnel body. The lining trolley is a special equipment that must be used in the secondary lining during the tunnel construction process, and is used for lining the inner wall of the tunnel. [0003] The tunnel steel formwork lining trolley in the prior art lacks a steel formwork lateral movement adjustment mechanism. During the construction ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention solves the lack of a steel formwork lateral movement adjustment mechanism for the tunnel steel formwork lining trolley in the prior art. During the construction process, it is necessary to adjust the position of the trolley entering the tunnel several times to ensure that the design centerline of the trolley is in line with the tunnel lining. The alignment of the centerline of the tunnel will cause low construction efficiency and slow progress of the project. A tunnel steel formwork lining trolley that is convenient for centering is provided.
