Detachable hook mechanism for carriage connection

Abstract

The invention belongs to the technical field of carriage connection, and particularly relates to a detachable hook mechanism for carriage connection. The detachable hook mechanism comprises a front carriage connecting rod, a first drive shell, a second drive shell and a rear carriage connecting rod. If a front carriage derails in the train running process, the front carriage can swing relative toa rear carriage, and in other words, the front carriage drives the front carriage connecting rod to swing. Due to swinging of the front carriage connecting rod, a first gear is driven to swing arounda second rotation shaft under the action of a first shaft sleeve. The carriage connecting rod drives the first gear to swing around a second rotation shaft so that a connecting gear sleeve can rotatethrough the first gear. The connecting gear sleeve rotates and drives the first drive shell to rotate. The first drive shell rotates and makes a limiting drive column rotate. In the limiting drive column rotation process, when one guiding groove in the limiting drive column is matched with a corresponding guiding notch in a limiting connection part, the rear carriage connecting rod can disengage from the front carriage along the corresponding guiding groove and the corresponding guiding notch; and train overturning is prevented.

Description

technical field [0001] The invention belongs to the technical field of carriage connection, and in particular relates to a detachable hook mechanism for carriage connection. Background technique [0002] At present, the traditional train carriages are connected to each other by couplings; the material of the couplings is relatively high; the friction between the couplings is severely damaged; if the front carriage derails during use, there will be swings between the front carriage and the rear carriage; If the couplers are interlocked and connected between the two carriages, when the front carriage derails and the rear carriage swings, the front carriage may drag the rear carriage through the engaged coupler to cause the rear carriage to roll over; Therefore, it is very necessary to design a train car connection mechanism that can completely separate the rear compartment from the front compartment when the front compartment is derailed and swings relative to the rear compart...

[0002] At present, the traditional train carriages are connected to each other by couplings; the material of the couplings is relatively high; the friction between the couplings is severely damaged; if the front carriage derails during use, there will be swings between the front carriage and the rear carriage; If the couplers are interlocked and connected between the two carriages, when the front carriage derails and the rear carriage swings, the front carriage may drag the rear carriage through the engaged coupler to cause the rear carriage to roll over; Therefore, it is very necessary to design a train car connection mechanism that can completely separate the rear car from the front car when the front car is derailed and swings relative to the rear car.
