One-way anti-slip device for railway vehicle

Abstract

The invention relates to a one-way slip stopper for railway vehicles, which comprises a wheel pressure plate, a casing, a roller mechanism, a clamping mechanism and a locking mechanism; the roller assembly includes a roller, and an upper part of the front end surface of the casing is provided with an avoidance The roller is arranged at the avoidance hole; the clamping mechanism includes clamping fin assemblies on both sides of the wheel pressure plate, the clamping fin assemblies include clamping fins, a rotating shaft and a connecting rod, and the clamping fins are arranged on the rotating shaft ; The locking assembly includes a push-pull plate, a compression spring and a lock. The rear end surface of the casing is provided with a through hole, and the head end of the push-pull plate is provided with a compression spring. The compression spring is located above the two connecting rods in the clamping mechanism. The middle part is provided with an inclined surface that can scoop up the connecting rod, and the rear part of the push-pull plate and the casing can be locked by a lock. The slip stopper of the present invention can be locked with the rail after being installed on the rail, can prevent theft from theft and prevent the destruction of terrorists, and can prevent the locomotive wheel from overturning, and can realize the stable slip stop of the railway wheel.

Description

technical field [0001] The invention relates to the technical field of railway transportation auxiliary equipment, in particular to a one-way anti-skid device for railway vehicles. Background technique [0002] Iron shoes are one of the anti-slip tools in railway shunting operations. At present, the iron shoes used on my country's railway stations are used to brake, which is to place iron shoes on one or two steel rails. After pressing the iron shoes, the wheels rolling forward will slide along the rails. For sliding friction, stop the detent wheel from advancing, and play a braking role. In order to prevent gaps between the wheels and the iron shoes in use, the existing iron shoes need to be hammered tightly by hand, commonly known as iron shoes, but the front end of the iron shoes is designed with a slope. Two situations will occur like this: one, the iron shoe is beaten too tightly, and it is difficult to take it out; two, the iron shoe is beaten loosely, the iron shoe i...

Problems solved by technology

In order to prevent gaps between the wheels and the iron shoes in use, the existing iron shoes need to be hammered tightly by hand, commonly known as iron shoes, but the front end of the iron shoes is designed with a slope. In this way, two situations will occur: 1. The iron shoes are too tight and it is difficult to take them out;

Another problem is that the old-fashioned iron shoes can be climbed over. On October 18, 2016, the special escort program of CCTV military documentary "Dreams in Heaven" was broadcast. The mosaic slipped 1.5m, almost causing the rocket vehicle transporting Tiangong-2's toxic propellant to roll over, causing serious casualties
