Drop panel jack-in wrought steel hook tail frame

Abstract

The invention discloses a splint inserted type coupler tail frame of forging steel, which is additionally provided with a forging steel splint based on a forging steel frame body provided with an upper pin hole and a lower pin hole; the two sides of the lower pin hole of the forging steel frame body are respectively provided with an L-shaped slideway; the two sides of the forging steel splint are respectively provided with a reversed L-shaped slide strip corresponding to the L-shaped slideway; the forging steel splint inserts a seal cover at the position of the lower pin hole of the forging steel frame body by the reversed L-shaped slide strip and the L-shaped slideway. The forging steel frame body includes a U-shaped forging steel framework and two side forging steel plates; the two side forging steel plates are respectively welded on the two sides at the front end of the U-shaped forging steel framework; the two L-shaped slideways are simultaneously forged and shaped with the U-shaped forging steel framework or welded on the lower frame plates at two sides of the lower pin hole; a locating mechanism is arranged between the forging steel splint and the forging steel frame body. A lug boss with an incline plane is arranged on the forging steel splint. The splint inserted coupler type tail frame of the forging steel has the advantages of reasonable design, high mechanical intensity, convenient loading and unloading, being capable of effectively preventing the coupler tail pin from falling off, higher framework intensity, etc. The splint inserted type coupler tail frame of the forging steel is applicable to be used in traction buffer device of a delivery truck, in particular to a delivery truck of 60tons.

Description

technical field [0001] The invention relates to a traction buffer device for railway wagons, in particular to a coupler frame with high mechanical strength and capable of effectively preventing coupler pins from falling off, which belongs to the connection device of railway vehicles. Background technique [0002] The coupler frame is a key part of the coupler buffer device of railway vehicles and freight cars. It is installed at both ends of the middle beam of the truck. The front end of the coupler frame is connected to the tail of the coupler. Transmission of longitudinal forces. The connection method between the coupler and the coupler frame is to insert the tail of the coupler into the front frame of the coupler frame, use a coupler pin to penetrate through the lower pin hole of the coupler frame, go upward through the tail pin hole of the coupler, and The upper pin hole of the tail frame is pierced, and the tail of the coupler can be installed in the frame body at the ...

AI Technical Summary

Problems solved by technology

But because the coupler pin penetrates into the lower pin hole, the tail pin hole and the upper pin hole successively from bottom to top, it is easy to fall off downwards. In order to prevent the pin from falling off, the traditional method is to use a φ20 bolt 3 to penetrate horizontally Pass through the flange 4 with holes in the middle on both sides of the lower pin hole of the coupler frame 2, and us
