Installing and cushioning device for tight-lock coupler

Abstract

The invention discloses an installing and cushioning device for a tight-lock coupler, which comprises an installation seat assembly, a supporting board, a driving rod, a driving pin, a rubber oscillating bearing, a shock absorber rubber, a connecting pin and a height adjusting nut, wherein two parallel installation boards are arranged on the installation seat assembly; the installation boards, the driving rod and the supporting board are connected through the driving pin; the driving pin and the supporting board form a revolute pair; the height adjusting nut can adjust the height of the supporting board; the driving rod is positioned between the two installation boards; the rubber oscillating bearing is arranged between the driving pin and the driving rod to form a revolute pair; and the connecting pin is also connected between the driving rod and the supporting board, and the connecting pin is sleeved with the shock absorber rubber. The installing and cushioning device for the tight-lock coupler is simple in structure, easy to manufacture, low in cost, convenient to install, reliable and flexible, and suitable for a locomotive needing to be provided with multiple sets of couplers, and meets the coupling performance requirement when a common metro shunting locomotive rescues a metro vehicle.

Description

technical field [0001] The invention relates to a coupler installation and buffer device for locomotives. Background technique [0002] The couplers installed on existing locomotives generally occupy a larger space due to their buffer devices and mounting seats, so that the inner trolley couplers cannot be installed on the locomotive, which makes the use efficiency of the locomotive low. And the coupler installation and buffer device of the prior art have complicated structure, higher cost, inconvenient installation, and can not satisfy the requirement that multiple sets of couplers are installed on the locomotive. Contents of the invention [0003] The object of the present invention is to provide a close-connected coupler installation and buffer device with simple structure, low cost and convenient installation, which can completely overcome the above-mentioned deficiencies in the prior art. [0004] The purpose of the present invention is achieved through the following...

AI Technical Summary

Problems solved by technology

[0002] The couplers installed on existing locomotives generally occupy a relatively large space due to their buffer devices and mounting seats, so that the locomotive can no longer be installed with inner tram couplers, which makes the use of the locomotive inefficient

Moreover, the coupler installation and buffer device of the prior art have complex structure, high cost, inconvenient installation, and cannot meet the requirements of multiple sets of couplers installed on locomotives.
