Open cut tunnel segment assembly trolley

Abstract

The invention discloses an open cut tunnel segment assembly trolley. The open cut tunnel segment assembly trolley comprises a track, a road wheel assembly, a lower side-slip assembly, a main supporting frame, an alignment formwork frame, an assembly formwork frame, a segment pushing bracket, an adjusting mechanism, an abut wall centralizing mechanism, a side wall centralizing mechanism and a traction mechanism; the bottom of the main supporting frame is connected with the road wheel assembly through the lower side-slip assembly, and the road wheel assembly walks along the track; the alignmentformwork frame is arranged at the middle position of the front part of the upper part of the main supporting frame through a first lifting mechanism, and an arch plate at the top of the alignment formwork frame is positioned; the assembly formwork frame is arranged on the rear part of the alignment formwork frame through the adjusting mechanism, and the assembly formwork frame positions a crown wall prefabricated block; the abut wall centralizing mechanism and the side wall centralizing mechanism are arranged on the two sides of the main supporting frame and used for centralizing and positioning an abut wall prefabricated block and a side wall prefabricated block; the segment pushing bracket tightly pushes the side surfaces of segment rings; and the traction mechanism drives the trolley towalk. According to the open cut tunnel segment assembly trolley, the whole-course mechanization is realized, the labor strength is alleviated, the segment assembly efficiency is improved, and the assembly precision is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, and more specifically relates to a segment assembling trolley for open hole tunnels. Background technique [0002] The railway tunnel is a channel specially used for train transportation. When the railway passes through the mountainous area, due to the limited traction capacity and the maximum slope requirement (less than 24%), it is necessary to overcome the elevation obstacle, and excavating the tunnel to cross the mountain is a reasonable choice. , Its function is to shorten the line, reduce the slope, improve the operating conditions, and increase the traction capacity. Between mountains, the mountain is easy to loosen, and rockfall is easy to occur, which affects the normal running of the train. [0003] At present, the existing railway open tunnel structure usually adopts the method of pouring concrete to form shed-like joints, and the inverted arch of the cast-in-situ...

Problems solved by technology

[0005] However, during the segment assembly process, since there is no special segment assembly equipment, the use of ordinary hoisting equipment is labor-intensive, the assembly efficiency is low, and it is difficult to ensure the assembly accuracy
