Problems solved by technology

When the rail car is transported or repaired and lifted, the pull rods and hydraulic shock absorbers are under relatively large force, which can easily damage the rubber joints of the pull rods and the hydraulic shock absorber; when the rail car derails on the line, there is no corresponding hanging device , generally cannot be lifted directly, and can only be handled by binding the bogie frame and the car body with rigging. When the railcar is lifted vertically or reset, the flexible connection between the bogie frame and the car body will be damaged or broken. , bringing huge safety hazards and economic losses to the overall recovery of rail cars

Embodiment Construction

[0012] given in the present invention figure 1 , figure 2 In the embodiment, the continuous work hanging device is composed of a car body 1, a frame 2, a car body traction seat 3, a hanging plate 4, and a hook plate 5. The hanging plate 4 is welded on the bogie frame 2, and the middle part of the side wall of the hanging plate 4 is provided with a hook; , is installed and fixed on the traction seat 3, and the hook on the hook plate 5 is combined with the hook on the hook plate 4 to form the connecting device on the railcar bogie frame 2 and the car body 1.

[0013] When the rail car is in the ready state, the connecting device connects the car body 1, the car body fifth wheel 3 and the bogie frame 2 together. The car body 1 is hoisted or jacked up, the traction seat 3 rises with the car body 1, and the hook on the hook plate 5 rises together with the car body traction seat 3 until the hook on the link plate 4 is combined with the hook on the hook plate 5 Together, the hook...

Abstract

A coupling device for a frame and bodywork is characterized by being composed of the bodywork, the frame, a bodywork traction seat, a hanging plate and a hanging hook plate. The hanging plate is welded to the frame, and hooks are arranged in the middle of the side wall of the hanging plate. The bodywork traction seat is welded to the bottom of the bodywork, the hanging hook plate is installed and fixed to the traction seat through bolts, spring cushions and a large gasket, hooks on the hanging hook plate and the hooks on the hanging plate are combined together, and therefore the coupling device for the frame and the bodywork of a rail car truck is formed. According to the coupling device, a rubber joint of an axle box pull rod and a hydraulic shock absorber are protected against damage, the lifting difficulty and potential safety risks after transferring or hoisting for maintenance or derailing of a car are avoided, the maintenance time is shortened, and economic benefits of an enterprise are improved.

Description

technical field [0001] The invention relates to a hitch device, in particular to a connecting device for a bogie frame of a railway rail car and a car body. Background technique [0002] In the existing railway rail car, the bogie is used as a bearing part, and the frame is its most important component. A traction rod is longitudinally installed between the bogie frame and the car body of the rail locomotive, but there is no vertical connecting device between the bogie frame and the car body. When the rail car is transported or repaired and lifted, the tension on each tie rod and hydraulic shock absorber is relatively large, and it is easy to damage the rubber joint of the tie rod and the hydraulic shock absorber; when the rail car derails on the line, there is no corresponding hanging device , generally cannot be lifted directly, and can only be handled by binding the bogie frame and the car body with rigging. When the railcar is lifted vertically or reset, the flexible co...
