Description

Damping type anti-slip iron shoe Technical Field The utility model relates to the technical field of railway anti-slip equipment, in particular to a damping anti-slip iron shoe. Background At present, when a railway vehicle stays temporarily or for a long time, a pair of iron shoes are usually arranged behind wheels of the railway vehicle to prevent serious accidents caused by the fact that the railway vehicle slips, the wheels of the railway vehicle slide along rails on the iron shoes, rolling friction between the wheels of the railway vehicle and the rails is changed into sliding friction, and strong friction generated between the wheels of the railway vehicle and the rails provides resistance for the railway vehicle to force the railway vehicle to stop slipping. The prior art iron shoe can not effectively prevent the railway vehicle from slipping, the iron shoe consists of a sole, a toe cap, a shoe edge and a shoe body, when the iron shoe brakes the railway vehicle to prevent slipping, the iron shoe only depends on the shoe edge and the sole to rub with a track, strong resistance can not be provided for the slipped railway vehicle, the railway vehicle still can drive the iron shoe to slide on the track for a long distance, the braking anti-slipping effect of the iron shoe is not ideal, and when the sole and the shoe edge of the iron shoe are polished and slipped, the friction coefficient between the iron shoe and the track can be reduced, so that the iron shoe can slide for a longer distance on the track, and the accident occurrence risk is high. Disclosure of Invention The damping anti-slip iron shoe can effectively prevent the railway vehicle from slipping, can effectively prevent the railway vehicle from slipping through the track bed resistance and the damping of the restorer, achieves the anti-slip effect, avoids the railway vehicle from driving the iron shoe to slide for a long distance, reduces the accident occurrence risk and improves the braking anti-slip effect. In order to achieve the aim, the damping type anti-slip iron shoe comprises an iron shoe body, a sleeper and a track, wherein the track is fixed at the top of the sleeper through a fastener bolt, swing damping mechanisms are symmetrically arranged on two sides of the iron shoe body, each swing damping mechanism comprises a fixing seat, a restorer and a swing assembly, and the restorer is arranged on the fixing seat and is parallel to the iron shoe body. The swinging component is matched with the fastening bolt, and pushes the sleeper under the action of the restorer so as to consume the kinetic energy of the railway vehicle by the resistance of the ballast bed, prevent the railway vehicle from slipping, and achieve the anti-slip effect. The swinging assembly comprises a swinging baffle, a middle connecting plate and a sliding shaft, wherein two ends of the middle connecting plate are respectively hinged with the swinging baffle and the sliding shaft, the sliding shaft is slidably sleeved on the fixed seat, one end of the sliding shaft is connected with a piston rod of the restorer, fixed shafts are symmetrically arranged on two sides of the skate body, the upper part of the swinging baffle is rotationally connected with the fixed shafts, and the lower end of the swinging baffle is lower than the upper end of the fastener bolt. The swinging baffle contacts with the fastening bolt to force the swinging baffle to swing backwards, the swinging baffle pushes the sleeper through the action of the restorer, the track bed damping is utilized to consume the kinetic energy of the railway vehicle, and when the resistance is larger than the restorer damping, the swinging baffle can pass over the fastening bolt, so that the kinetic energy of the railway vehicle is consumed through the restorer damping to prevent the railway vehicle from escaping. Preferably, the skate body comprises a sole, a skate body and a shoe edge, wherein the skate body is fixed at the top of the sole, the front end of the sole is provided with a shoe tip, the shoe edge is symmetrically arranged on two sides of the sole, the oblique body blocks wheels of the railway vehicle so as to prevent the wheels from crossing the shoes, and the shoe tip is convenient for the wheels of the railway vehicle to go up to the shoes, so that the shoe body is prevented from tilting. Preferably, the fixing seat comprises a mounting block and a guide block which are fixed on the shoe body, wherein the mounting block is provided with a threaded hole, the restorer is a hydraulic buffer, the hydraulic buffer is sleeved in the threaded hole and is in threaded connection with the mounting block, the threaded hole provides a mounting position for the hydraulic buffer, the swing baffle pushes the sleeper through the hydraulic buffer, and kinetic energy of the railway vehicle is consumed through damping of the hydraulic buffer. Preferably, the guide block is provided with a sliding hole with an axis coinc
