A device and method for detecting the three-state and coupling state of a torpedo tank car coupler

Abstract

The invention discloses a detection device and method for the three-state and connected state of a coupler of a torpedo tank car. The detection device comprises: a mounting bracket, a knuckle sensor fixed on the mounting bracket, a hook lock pin sensor, a connecting sensor, and a motion conversion mechanism. The knuckle sensor and the motion conversion mechanism are installed on the same plane to detect the position of the knuckle; the hook lock pin sensor is installed directly below the hook lock pin to detect the position of the hook lock pin; the hook sensor is installed on the mounting bracket The front end of the hook is used to detect the coupling status of the coupler after coupling. The motion conversion mechanism is used to convert the rotation of the knuckle into the linear motion of the sensing shaft. The invention reduces the difficulty of detecting the position of the knuckle by converting the rotation of the coupler into the linear motion of the induction shaft, and facilitates the indirect detection of the position of the knuckle. The detection of coupler status realizes automation, remoteness and informatization.

Description

technical field [0001] The invention relates to the automation field of railway transportation equipment in the metallurgical industry, and more specifically refers to a detection device and detection method for the three-state and coupling state of a torpedo tank car coupler. Background technique [0002] The coupler equipped on the torpedo tanker is 2# coupler, which is made of cast steel and mainly consists of coupler neck 1, coupler lock pin 2, coupler head 3, knuckle tongue pin 4, knuckle tongue 5 and other components. There are three working states of the coupler: There are three states, that is, locked position, unlocked position, and fully opened position. [0003] CN205451655U discloses a teaching mold for the automatic demonstration of the three-state test of the coupler. The three-state process of the coupler can be demonstrated quickly and intuitively automatically through this mold. [0004] figure 1 Schematic diagram showing the locked position of the couple...

Problems solved by technology

However, at this stage, the coupler is not equipped with relevant testing equipment, and the state of the coupler cannot be grasped, so it is impossible to realize the independent coupling and decoupling operation in an unmanned state.
