Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Such as Figure 1~2 As shown, a coupler maintenance tool includes a base 1 , an outer hardware 2 , an inner slider 3 and a driving mechanism 5 .

[0022] The base 1 is used to support other parts of the vehicle inspection coupler repair tool. In a preferred solution, the base 1 includes a bottom plate and two support plates vertically welded on the bottom plate.

[0023] The two ends of the external fixture 2 are symmetrically welded with rotating shafts 4...

Abstract

The invention discloses a car coupler overhauling tool, and belongs to the technical field of train maintenance equipment. The car coupler overhauling tool comprises a base, an outer fixing part, an inner sliding part and a driving mechanism, wherein the outer fixing part is rotationally matched with the base through rotating shafts fixedly arranged at two ends of the base, the outer end of one rotating shaft penetrates through the base and is fixedly connected with the driving mechanism, the inner sliding part is of a structure which is round outside and square inside, and the inner sliding part is in interference fit with the interior of the outer fixing part. According to the car coupler maintenance tool, not only can the upper angle and the lower angle and the radial angle of a car coupler be adjusted repeatedly, and the detection, flaw detection, overhaul, welding and the like on the car coupler are realized, but also the "tri-state" detection of the car coupler can also be realized.

Description

technical field [0001] The invention belongs to the technical field of train maintenance equipment, in particular to a 120-type integrated air brake system. Background technique [0002] The coupler refers to the hook at both ends of the train wagon or locomotive, which is used to realize the connection between the locomotive and the vehicle or between the vehicle and the vehicle, transmit the traction and impact force, and keep a certain distance between the vehicles. It has the functions of connection, traction and buffering. role. [0003] The coupler consists of three parts: the hook head, the hook body and the coupler tail. The thick part at the front end of the coupler is called the gib head, in which there are knuckle tongue, knuckle pin, lock lifting pin, knuckle push iron and hook lock. The rear part of the coupler is called the coupler tail, and a vertical flat keyhole is opened on the coupler tail so as to connect with the coupler tail frame. The coupler is one...
