Parking brake state detecting device

Abstract

The invention discloses a parking brake state detecting device which comprises a sensor mounting bracket, a proximity switch and an induction plate. Brake rails are located between tracks; a driving device is located between the brake rails, and the driving device controls the brake rail to move on the tracks, the sensor mounting bracket is connected to the tracks, the proximity switch is mountedon the sensor mounting bracket, the induction plate is connected to the brake rails, and the proximity switch can receive positioning signals of the induction board while the induction board moves along with the brake rails. An anti-slip device is installed on the driving device; the anti-slip device includes an anti-slip device crossbar, an anti-slip device rotating bar, an anti-slip device hydraulic cylinder and an anti-slip device plate; the anti-slip device plate is connected with the anti-slip device rotating bar in a rotatable manner via an anti-slip device connecting piece; the anti-slip device crossbar is symmetrically distributed on both sides of the anti-slip device hydraulic cylinder, the two ends of the anti-slip device crossbar are respectively connected with the anti-slip device rotating bar, and a middle part of the anti-slip crossbar and the brake rails are connected.

Description

technical field [0001] The invention belongs to the technical field of railway train parking brakes, and in particular relates to a parking brake state detection device. Background technique [0002] At present, parking brakes for trains usually use two-position infrared sensors or metal detection. For train parking brakes, which are usually used in open-air working environments, the detection device usually needs to face extreme working conditions such as humidity, rainy days, many objects or piles of debris. The detection device usually has the following failures: 1. The sensor cannot receive signals due to fog; 2. Poor contact due to weathering in the field environment; 3. Due to misdetection of sundries, the brake position and release position sense signals at the same time Signal conflicts caused by false detection. [0003] These failures may cause the system to report an error, requiring the staff to re-confirm the fault clearly, increasing the work of the staff, or...

The detection device usually has the following failures: 1. The sensor cannot receive signals due to fog; 2. Poor contact due to weathering in the field environment; 3. Due to misdetection of sundries, the brake position and release position sense signals at the same time Signal conflict due to false detection

[0003] These failures may cause the system to report an error, requiring the staff to re-confirm the fault, increase the work of the staff, and cause a safety accident if it is serious
