Embodiment Construction

[0025] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0026] like figure 1 , figure 2 The structure of the present invention shown is a buffer spring pressing device for a molten iron tank car, including a base 1 . It is a replacement and maintenance spring pressing device after the spring of the buffer spring of the molten iron tank frame is fatigued and broken, and is used for spring compression during the maintenance of the buffer of the molten iron tank car.

[0027] Timely maintenance and replacement of the buffer spring plays a pivotal role in maintaining the normal and safe operation of the high-temperature container of the molten iron tanker, reducing the harmful coupling tr...

Abstract

The invention discloses a spring compression device of a buffer of a molten iron tank truck. The device comprises a base, a spring stop seat and a jack stop seat are arranged at the two ends of the base respectively, and the spring stop seat and the jack stop seat are firmly connected with the base; a jack fixing support firmly connected with the base is further arranged on the base, and a jack jacking rod supporting hole is formed in the jack fixing support; the bottom face of a jack which is horizontally arranged is attached to the surface of the jack stop seat, and a jacking rod of the jack penetrates through the jack jacking rod supporting hole. By the adoption of the technical scheme of the spring compression device, through the usage of a special hold-down tool, labor intensity and spring self-damage are lowered, safety and stability in the spring installation process are improved, ordinary maintenance of the molten iron tank truck is facilitated, the maintenance time is saved, and the difficult problems that in the spring installation and compression processes, time and labor are consumed, and springs are prone to bursting and falling to hurt people are solved; the springs are installed in a nondestructive mode, the service lives and maintenance cycles are prolonged, and the time for detaining the truck and conducting maintenance is shorted.

Description

technical field [0001] The invention belongs to the technical field of rail transportation vehicles. More specifically, the present invention relates to a spring pressing device for a buffer of a molten iron tank car. Background technique [0002] The molten iron tank car is a special vehicle for transporting high-temperature liquid containers on the track. In the prior art, the coupler buffer of the molten iron tank car is the 13# coupler that is commonly used in domestic train vehicles. [0003] It is composed of coupler, buffer spring, coupler frame, slave plate, etc., and is installed in the traction beam at the end of the vehicle chassis. The spring in the buffer buffers and attenuates the traction force and impact force. The coupler is composed of three parts: the coupler head, the coupler body and the coupler tail, which realizes hooking or unhooking, so that the vehicle can be connected or separated. [0004] The coupler buffer device for hot metal tank car (ZT-65...
