A special rescue hook for Voith

Abstract

The invention relates to a rescue shackle, in particular to a rescue shackle special for Voith. The rescue shackle special for Voith comprises a shackle body end plate, a shackle body main plate, a shackle tongue and a shackle plate. The outer end of the shackle body main plate is fixedly provided with the shackle body end plate, and reinforcing plates are arranged on the upper portion and the twosides of the connecting position of the shackle body main plate and the shackle body end plate; a square hole A used for storing the shackle tongue is formed in the middle of the shackle body end plate, and a square hole B is formed in the middle of the shackle body main plate; an extending notch is formed in one side edge of the square hole B and internally provided with the shackle plate connected with one end of the shackle tongue; the shackle tongue comprises two connecting plates, a connecting shaft and a pin shaft A, and the two connecting plates are arranged inside the square hole A ina parallelly spaced mode; the connecting shaft is arranged between the outer ends of the two connecting plates, and pin holes are formed in the side faces of the other ends of the two connecting plates; and the pin shaft A is arranged between the two pin holes. According to the rescue shackle special for Voith, after coupling, a shackle tongue and a shackle plate of a Voith vehicle shackle form aparallelogram with the rescue shackle, and the purposes that tension is balanced, and the vehicle shackle cannot be uncoupled accidentally are achieved.

Description

technical field [0001] The invention relates to a rescue shackle, in particular to a Voith-specific rescue shackle. Background technique [0002] As we all know, with the development of high-speed intercity railway transportation and urban rail transit, high requirements are put forward for the coupler buffer system of rolling stock: the coupler is convenient for coupling and uncoupling, and the mechanical, air and electrical connections between vehicles can be quickly realized ; The gap between the coupler connection should be as small as possible; the coupler buffer system should have a large buffer capacity, which can ease the longitudinal impact of the vehicle during normal operation and coupling; the coupler buffer system should have an energy-absorbing protection device. When the impact of the coupling speed is allowed, it can effectively protect the vehicle body from damage and the passengers in the vehicle from injury; the automatic couplers commonly used on railways...

[0002] As we all know, with the development of high-speed intercity railway transportation and urban rail transit, high requirements are put forward for the coupler buffer system of rolling stock: the coupler is convenient for coupling and uncoupling, and the mechanical, air and electrical connections between vehicles can be quickly realized ; The gap between the coupler connection should be as small as possible; the coupler buffer system should have a large buffer capacity, which can ease the longitudinal impact of the vehicle during normal operation and coupling; the coupler buffer system should have an energy-absorbing protection device. When the impact of the coupling speed is allowed, it can effectively protect the vehicle body from damage and the passengers in the vehicle from injury; the automatic couplers commonly used on railways are difficult to meet the above requirements, and the Voith close-fitting coupler can be well It meets the above requirements, so it has been widely used in EMUs and urban rail vehicles around the world. However, the current rescue hooks are mainly for ordinary couplers such as No. 13, No. 15, and No. 17. There is a special rescue hook device for EMUs with Voith tight-fitting couplers and derailment rescue operations for urban rail vehicles; therefore, a Voith special rescue hook with simple structure, small size, and convenient coupling and uncoupling is proposed.
