Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway equipment, in particular to a screw-type railway vehicle anti-slip device. Background Art
[0002] Train slippage refers to the displacement of a railway vehicle due to the natural leakage of brake cylinder pressure air after the vehicle stops, caused by external forces such as slope, wind, and vibration. Slippage seriously endangers the safety of railway transportation.
[0003] The existing patent with authorization announcement number CN2184896163U discloses a railway vehicle anti-slip fastener, including a hook and a screw, one end of the screw is fixed with a connection seat, the connection seat is vertically rotatably connected with a hinge seat, the tail end of the hook is horizontally hinged on the hinge seat; the screw is threadedly connected with a nut seat, and the nut seat is hinged with a clamping seat, and the other end of the screw is clamped with a crank. The utility model provides a hinge seat so that the hook can rotate axially and swing radially, thereby overcoming the problem that the hook is not easy to hook the hand brake chain ring.
[0004] The above device can make the hook both rotate axially and swing radially, thus overcoming the problem that the hook is not easy to hook the handbrake chain ring. However, when using the anti-slip fastener, the brake is still tightened manually. However, since the anti-slip fastener is achieved by rotating the threaded rod, the workload for workers is large when installing it, which reduces work efficiency. In addition, when workers are installing the device, the device is in a loose state when suspended, so the hook is easy to slip when the workers perform subsequent operations, which increases the difficulty of the workers' work. Moreover, after tightening, due to the external environment, the train moves in the opposite direction, causing the hook to fall off, resulting in the train slipping, which seriously endangers the safety of railway transportation.
