Automatic positioning vertical steering track changing steel formwork trolley

Abstract

An automatic positioning vertical steering track-changing steel mold trolley. The bottom of the steel mold trolley is equipped with a walking wheel group that can rotate along the vertical shaft. The horizontal track and the longitudinal track are arranged in a "well" shape. The position is equipped with a track-turning device; there are 4 walking wheel sets, the transverse distance between the walking wheel sets corresponds to the longitudinal track, and the longitudinal space between the walking wheel sets corresponds to the transverse track; in the track-turning device, the turning The rail is fixedly installed on the transfer rail plate, and the transfer rail disc is rotatably connected with the transfer rail embedded part through the transfer rail rotating shaft at the bottom. The present invention provides an automatic positioning vertical steering rail changing steel mold trolley, through the set staggered rails, and a rotatable rail switching device is provided at the staggered place, so as to realize vertical steering and rail changing conveniently, and has high safety and will not derailed. The set positioning transmitter and positioning receiver, together with the jacking device, can accurately locate the steering position and realize reliable track change steering.

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
