Abstract

The invention discloses a hydraulic buffer stopper, which is a safety device for preventing vehicles from rushing out of line terminal. A buffer head of a fixed hydraulic buffer stopper is tightly and fixedly connected with a plunger bolt of a hydraulic buffer assembly, connecting plates at two sides of an oil cylinder of the hydraulic buffer assembly are connected with supporting arms at the left and right of a fixed bracket via bolts, the rear end of the hydraulic buffer assembly is connected with a retaining wall via a bolt for buffer seat, the retaining wall can be left out in case of low vehicle speed, lower portions of the supporting arms at the left and right of the fixed bracket are connected with a basic rail of the line via bolts, a buffer head of a sliding hydraulic buffer stopper is tightly and fixedly connected with the plunger bolt of the hydraulic buffer assembly, the connecting plates at two sides of the oil cylinder of the hydraulic buffer assembly are connected with supporting arms at the left and right of a sliding bracket, a damper at the lower portion of the sliding bracket is tightly and fixedly clamped on the head of the basic rail of the line via the bolt and is tightly inserted between a spring plate and a friction base via a taper. Such a stopper plays the role of buffering and absorption of impact energy for humping vehicles, thereby guaranteeing shunting safety.

Description

technical field [0001] The hydraulic buffer vehicle stopper is arranged at the end line terminal of a rail line, is a safety device for preventing vehicles from rushing out of the line terminal, and belongs to the technical field of rail traffic safety equipment. Background technique [0002] At present, there are two types of stoppers installed at the terminals of rail transit lines: fixed type and sliding type. The buffer head is used to contact the sliding coupler to prevent the vehicle from running and achieve the purpose of parking. Although the buffer head is provided with a buffer rubber plate, the energy absorbed is small, and when the impact force is large, there is a danger of crashing the coupler. For preventing the generation of above-mentioned hidden danger, design, manufacture a kind of car stopper that has sufficient car resistance, and does not damage the coupler again is the safe production problem demanding prompt solution.
