Balancing device used for transition draw gear

Abstract

A balancing device used for a transition draw gear is arranged on the upper end face of the transition draw gear. The balancing device comprises rotating shafts, a rotating rod and a top base, wherein the rotating shafts, the rotating rod and the top base are arranged on the transition draw gear. The rotating rod comprises an upper end plate and a lower end plate, wherein a sloping embossment is arranged between the upper end plate and the lower end plate, the sloping embossment is located on a side face of the lower end plate and of a one-piece protruding structure, by taking the upper end plate and the lower end plate of the rotating rod as the reference, the sloping embossment is of a structure of inclining out of the rotating rod in the longitudinal direction, one end of the rotating rod is arranged on one of the rotating shafts, the other end of the rotating rod is provided with a hinge pin, a swing bolt is further arranged on the hinge pin, and the rotating rod can rotate around the one of the rotating shafts and hinged to the swing bolt through the hinge pin. A through hole is formed in the top base, the swing bolt penetrates through the through hole of the top base, the tail end of the swing bolt is fixedly provided with a nut, a spring is arranged between the nut and the through hole of the top base, and the diameter of the spring is larger than the diameter of the through hole of the top base. According to the balancing device, the phenomenon that the head of transition draw gear falls when the draw gear is coupled up can be effectively avoided, and the transition draw gear is kept horizontal after being installed.

Description

technical field [0001] The invention relates to a balancing device for a transitional coupler, in particular to a balancing device for a transitional coupler adapted to a 15 / 13th coupler and closely connected to the coupler. Background technique [0002] The transitional coupler is an important device for shunting operations, train return and rescue. In the field of rail vehicles, the transitional coupler with the 15 / 13 coupler adapted to the close-fitting coupler is very common. [0003] The existing transitional coupler does not have a balancing device. During field application, due to the large gap between the No. 15 and No. 13 couplers, the close-fitting hook end of the transitional coupler will "bow its head" under the action of its own weight after installation, making the close-fitting hook end It is not easy to connect with the official coupler, and the connection speed must be increased to successfully connect. This not only easily causes damage to the closely conn...

Problems solved by technology

[0003] The existing transitional coupler does not have a balancing device. During field application, due to the large gap between the No. 15 and No. 13 couplers, the close-fitting hook end of the transitional coupler will "bow its head" under the action of its own weight after installation, making the close-fitting hook end It is not easy to connect with the official coupler, and the connection speed must be increased to successfully connect

This will not only easily cause damage to the close coupler, but also may have a certain adverse effect on the car body

[0004] At the shunting operation site, some shunting workers temporarily add wood chips or iron sheets to the underside of the 15 / 13 hook coupling surface, which can alleviate the "head bowing" phenomenon to a certain extent, but this method is not easy to operate and cannot fundamentally Solve the problem
