Connecting and locking mechanism for train tail safety protecting device

Abstract

The invention discloses a connecting and locking mechanism for a train tail safety protecting device. The connecting and locking mechanism for the train tail safety protecting device comprises a rotary hand wheel (6), a screw rod (5), a fixed hook component (2), a screw barrel connecting bar (3) and a movable hook component (1), wherein the end of the screw rod (5) is firmly connected with the rotary hand wheel (6); the fixed hook component (2) is connected with a cast hole of a train hook at the tail of the train; one end of the screw barrel connecting bar is hinged with the fixed hook component (2) while the other end is in thread connection with the screw rod (5); the movable hook component (1) is connected with the cast hole of the train hook at the tail of the train and is movably connected on the screw barrel connecting bar (3), and one end of the movable hook component is clamped in the rotary hand wheel (6). The movable hook component (1) is driven to keep away from the fixed hook component (2) or get close to the fixed hook component (2) through rotating the rotary hand wheel (6); the movable hook component (1) is capable of rotating along with the screw sleeve connecting bar (3). The connecting and locking mechanism enables the connection between the train tail device and the train tail to be more agile, enables the mounting to be more convenient, and has better adaptability.

Description

technical field [0001] The invention relates to a connection mechanism, in particular to a connection locking mechanism used for a row tail safety protection device. Background technique [0002] The train tail safety protection device, referred to as the train tail device, is a special transportation safety device developed for improving the safety of railway transportation when the tail of the freight train is cancelled, and no one is on duty at the tail. Before each freight train departs, a special column tail (i.e. train tail) operator is responsible for hanging the train tail device on the tail coupler of the train formation. The tail device in the prior art is generally connected to the tail of the train through a connecting mechanism. The connecting mechanism has 2 to 4 L-shaped claws, which are used to extend into the four casting holes of the coupler at the tail of the train, thereby clamping the tail device On the coupler at the rear of the train. However, due to...

Problems solved by technology

However, due to the mutual positions and shapes of the four casting holes at the tail of different trains may not be the same, and the existing L-shaped claws connected to the connecting mechanism of the tail device are fixedly connected and cannot be stretched, resulting in inflexible connection and difficult installation. inconvenient

In addition, the existing connecting mechanism is easy to loosen due to vibration during the running of the train, posing potential safety hazards
