Vertical Steering Track Changed Steel Die Trolley

Abstract

Disclosed is a perpendicular steering and rail changing steel mould bogie. The bottom of the perpendicular steering and rail changing steel mould bogie is provided with four travelling wheel sets rotating along a perpendicular rotating shaft, transverse rails and longitudinal rails are disposed in #-shape, and rail changing devices are arranged at staggered positions of the transverse rails and the longitudinal rails, transverse distance among the travelling wheel sets corresponds to the longitudinal rails, and longitudinal distance among the travelling wheel sets corresponds to the transverse rails; in the rail changing devices, rotating rails are fixed on rail changing plates, and the rail changing plates are rotationally connected with rail changing embedded parts through rail changing rotating shafts at the bottom. By the aid of the staggered rails and the rotatable rail changing devices at the staggered positions, perpendicular steering and rail changing can be conveniently realized, safety is high and no derailing is caused. By a positioning transmitter and a positioning receiver and coordination of a jacking device, steering positions can be accurately located and reliable rail-changing steering is realized.

Description

technical field [0001] The invention relates to the field of steel formwork trolleys for tunnel construction, in particular to a steel formwork trolley for 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 at the intersection.

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
