Bogie deflection detection cylinder

Abstract

The invention relates to the technical field of railway locomotive vehicle coupling, in particular to a bogie deflection detection cylinder. The cylinder comprises a bogie deflection detection cylinder body installed on a bogie side beam and located between two limiting plates below a vehicle body, two pistons are arranged in the bogie deflection detection cylinder body, the two pistons divide the bogie deflection detection cylinder into a front cavity, a middle cavity and a rear cavity, piston rods are installed on the two pistons, the two piston rods of the bogie deflection detection cylinder can make contact with the limiting plates on the corresponding sides after extending out, the middle cavity is connected with an air inlet pipe, and a three-way electromagnetic valve with one end communicated with the outside is mounted on the air inlet pipe; and the front cavity and the rear cavity are connected with oil pipes, and the two oil pipes are connected to the rear cavities of the two position adjusting piston cylinders correspondingly, so that hydraulic oil can push piston rods of the position adjusting piston cylinders installed on the two sides of a car coupler at the end of a car body to abut against the car coupler after entering the rear cavities, and therefore the position of the car coupler is adjusted.

Description

technical field [0001] The invention relates to the technical field of railway locomotive and vehicle coupling, in particular to a bogie deflection detection cylinder. Background technique [0002] The coupler refers to the hook at both ends of the train vehicle or locomotive, which has the functions of connection, traction, buffering and separation. At present, the connection mode of railway trains is to connect two adjacent vehicles through couplers. When connecting, usually the shunting officer sends out a connecting signal, and the shunting driver pushes the front car to dock with the rear car. [0003] However, in order to adapt to the change of the track, the coupler is specially arranged as a structure that can swing left and right relative to the car body, that is, the coupler can move around the fixed axis. When the two vehicles are connected to each other, it must be ensured that the longitudinal centerlines of the two butt coupler couplers are close to the same ...

Problems solved by technology

[0004] However, in the above-mentioned connecting process, the first is that the safety is low. If the carriage slips, it will easily cause casualties and bring great personal safety hazards to the shunting personnel; the second is that the efficiency is low. Whether the relative position can be connected directly, it needs to wait until the connected vehicle is close to the connected vehicle, and after the shunting locomotive is parked, the shunting personnel will arrive at the connecting location, check on site, adjust the position of the coupler, and then notify the shunting driver Carry out the coupling operation; the third is that it is easy to damage the coupler. If the shunting personnel fail to find out that the position of the coupler is improper in time, the two coupled vehicles may form a "fist hook" due to the misalignment of the coupler, which will cause the coupler to fail to be connected correctly.
