The invention relates to the technical field of hydraulic machinery, and discloses a hydraulic device for vehicle stopping at a curve; the device comprises a slide rail seat, a plurality of slide rails are arranged in the slide rail seat, a hydraulic bin is arranged in the slide rail seat, a third piston is connected in a second rectangular groove, and a steel nail is connected to the upper end of the third piston. A round hole is formed in the sliding rail seat, a blocking plate is arranged on the upper side in the sliding rail seat, and a curled spring is connected between the rotating blocking wheel and the blocking plate. A third piston is pushed by a baffle through a second push rod, a second piston extrudes hydraulic oil in a hydraulic device, and the blocking plate pulls a curled spring on a rotating blocking wheel; a first piston extrudes hydraulic oil in the hydraulic bin, hydraulic oil entering the second rectangular groove pushes the third piston to move upwards, the third piston drives a steel nail on the third piston to deflate wheels impacting a vehicle, and the structure solves the problems that the vehicle blocking performance is poor, and the vehicle is prone to turning over after rebounding.
Description
technical field [0001] The invention relates to the technical field of hydraulic machinery, in particular to a hydraulic device for blocking a car on a curve. Background technique [0002] The car buffer device is a kind of railing machine installed on the motor vehicle passage, which has a barrier machine that restricts the entry and exit of vehicles. The car stopper is widely used at the entrance and exit of the expressway and the entrance and exit of the parking lot. Due to skidding, brake failure or too fast cornering speed, etc., the vehicle may be collided or crashed. [0003] Most of the current car stop devices are fixed time car stoppers and sliding car stoppers. Among them, the fixed car stoppers have a low braking capacity and are likely to cause damage to the vehicle, while the sliding car stoppers have higher braking capacity but require more For long lines, with the development of hydraulic technology, using hydraulic buffer devices to buffer vehicles has a go...
