A detachable hook mechanism for carriage connection based on gear transmission

Abstract

Provided is a detachable coupler mechanism for coupling carriages based on gear transmission. The mechanism comprises a front carriage connecting rod (1), a driving housing (7) and a rear carriage connecting rod (8). The derailment of a front carriage causes the front carriage to drive the front carriage connecting rod to swing, and the front carriage connecting rod further drives a first gear (2) to rotate; the rotation of the first gear drives three second gears (5) to rotate; the rotation of the three second gears drives the driving housing to rotate; the rotation of the driving housing drives three fourth gears (10) to rotate; and the rotation of the three fourth gears drives a limiting drive gear (15) to rotate. During the rotation of the limiting drive gear, when one guide slot (27) in a limiting drive cylinder cooperates with a corresponding guide notch (25) in a limiting coupler (16), the rear carriage connecting rod and a limit block (24) mounted thereon will disengage from the front carriage along the corresponding guide slot and guide notch, thus preventing a train from turning over.

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 based on gear transmission. 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 r...

[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.
