Automatic locating perpendicular steering rail transfer steel mold trolley

Abstract

Provided is an automatic locating perpendicular steering rail transfer steel mold trolley. Travelling wheel sets capable of rotating along a perpendicular rotary shaft are arranged at the bottom of the steel mold trolley. A transverse rail and a longitudinal rail are arranged in the shape like a Chinese character ''jing''. The staggered position of the transverse rail and the longitudinal rail is provided with a rotary rail device. The number of the travelling wheel sets is four. The transverse space and between the travelling wheel sets corresponds to the longitudinal rail. The longitudinal space and between the travelling wheel sets corresponds to the transverse rail. In the rotary rail device, a rotary rail is fixedly installed on a rotary rail disk which is rotationally connected with a rotary rail embedded part through a rotary rail rotary shaft at the bottom. According to the automatic locating perpendicular steering rail transfer steel mold trolley provided by the invention, the staggered rails are arranged, and the staggered position is provided with the rotary rail device capable of rotating, so that perpendicular steering rail transfer is achieved conveniently, the safety is high, and derailing does not occur. A locating emitter and a locating receiver are arranged and matched with a jacking device so that a steering position can be located accurately, and reliable rail transfer steering is achieved.

Description

technical field [0001] The invention relates to the field of steel formwork trolleys for tunnel construction, in particular to a steel formwork trolley with automatic positioning, vertical steering and track change. Background technique [0002] Tunnel lining concrete is generally constructed with steel formwork trolleys, and the weight of large steel formwork trolleys can reach 310t. After the completion of a tunnel lining, the steel formwork trolleys are usually removed for construction of the next tunnel. Reinstalling in another tunnel not only increases the construction cost but also affects the construction progress. [0003] Chinese patent documents CN100554582C and CN100542937C disclose a "well"-shaped intersecting vehicle running track and a vehicle device moving on the "well"-shaped crossing track, using a special "convex"-shaped guide rail, which is fixed at the intersection, And the position of the track at the intersection is disconnected so that the wheels turn...

AI Technical Summary

Problems solved by technology

The problem is that each wheel of the wheel set needs to be driven by a separate driving device, and 8 wheels need 8 driving devices, the structure is more complicated, and special tracks are required, and the cost is high

At the turning position of the wheel, the precision requirement is high and the control is difficult. When the wheel and the ground slip, it is easy to fail to turn, and it is difficult to manually compensate
