Abstract

The invention belongs to the technical field of rail engineering truck body steel structure unwheeling. The width-adjustable rail engineering truck body unwheeling platform comprises two unwheeling piers, a cross beam, a first hydraulic jack, a second hydraulic jack and a transverse movement adjusting unit, wherein the two unwheeling piers are correspondingly arranged left and right. The two ends of the cross beam are fixedly arranged on the two unwheeling piers respectively. The first hydraulic jack is arranged at the first end part of the cross beam. The second hydraulic jack is arranged at the second end part of the cross beam. The transverse movement adjusting unit is arranged between at least one of the first hydraulic jack and the second hydraulic jack and the cross beam, and the transverse movement adjusting unit adjusts the position of the first hydraulic jack or / and the second hydraulic jack on the cross beam. The overall structural design is reasonable, the structural stability is high, the width adjustment is made more convenient, the practicability is high in the operations of rail engineering trucks and the adjustment is made convenient.

Description

technical field

[0001] The invention belongs to the technical field of rail engineering car body steel structure frame car, and in particular relates to a rail engineering car body frame frame platform with adjustable width. Background technique

[0002] In the process of assembling the steel structure parts of the rail engineering vehicle, to erect the body of the rail engineering vehicle requires the use of a crown block to place four piers (six piers are required for the deflection of the underframe of the shunting body) Suitable location, the existing rail engineering vehicles are of various types, with different widths and lengths. The shortage of vehicle resources has also become a bottleneck in the manufacture of rail engineering vehicles.

[0003] Therefore, a new structural design of the car pier is required to meet the requirements of construction operations. However, in the new structural design of the car pier, not only the stability of its structural strength m...
