Description

Car arrester for rubber-tyred car Technical Field The invention relates to the technical field of engineering vehicles, in particular to a vehicle arrester for a rubber-tyred vehicle. Background The rubber-tyred vehicle is used as one of main tools of underground transportation, and the design and the use of the intelligent vehicle arrester reduce the manual operation links, improve the intelligent level, and greatly reduce the occurrence of underground transportation safety accidents and 'three violations' behaviors for the new idea of underground transportation injection technology management. The traditional car arrester is that the driver and passengers set up the car arrester for manual operation under the condition of people-vehicle separation, has the potential safety hazard, and the car arrester position is narrower simultaneously. The patent number CN202422154353.9 discloses an automatic car arrester of a rubber-tyred car, which comprises a rubber-tyred car body, wherein a controller is arranged in a cab of the rubber-tyred car body, one side of the rear end of the rubber-tyred car body is provided with an air storage bag, the rear ends of the rubber-tyred car body close to rear wheels on two sides are respectively provided with car arrester components, the two car arrester components comprise first hydraulic cylinders which are detachably and fixedly connected to the bottom of the air storage bag and the bottom of the lower side of the rear end of the rubber-tyred car body, the telescopic ends of the two first hydraulic cylinders are respectively and fixedly connected with a connecting block, and the two first hydraulic cylinders are respectively and electrically connected with the air storage bag and the controller.
