Antiskid self-locking rail clamping device for rail mounted gantry crane

Abstract

The invention discloses an antiskid self-locking rail clamping device for rail mounted gantry crane. The rail clamping device comprises a frame, wherein a self-locking screw rod is arranged at the middle part of the frame; a thrust bearing is arranged between the self-locking screw rod and the frame; a handle is arranged at the top end of the self-locking screw rod; a stop nut is arranged at the bottom end of the self-locking screw rod; a sliding nut capable of moving up and down along the self-locking screw rod is arranged at the middle part of the self-locking screw rod; a pair of clamping pincers for clamping a rail are arranged on frames on the two sides of the self-locking screw rod; lower rolling wheels are arranged at the tail end of the clamping pincers; a first connecting rod is connected between the clamping pincers and the sliding nut; a self-locking box body is arranged at a position above the rail of the rail clamping device; a second connecting rod is connected between the self-locking box body and the clamping pincers; and the self-locking box body is used for preventing the rail clamping device sliding along the rail.

Description

technical field [0001] The invention relates to a rail clamp structure of a rail gantry crane, in particular to an anti-skid self-locking rail clamp for a rail gantry crane. Background technique [0002] At present, with the continuous development of the production economy, the number of rail gantry cranes is gradually increasing. However, when a gantry crane is hit by a typhoon, it will often move on the track, and even slippery for a long distance, which will cause serious harm to human safety and mechanical equipment. At present, there are many windproof devices for gantry cranes, such as windproof brakes, which only play a certain role when the wind force is small. When encountering a typhoon, the rail clamp will inevitably slip and cannot be increased. The force self-locking makes the gantry crane slide on the track, and the braking effect is poor.

However, when a gantry crane encounters a typhoon, it will often move on the track, and even slippery for a long distance, which will seriously endanger human safety and mechanical equipment.

At present, there are many windproof devices for gantry cranes, such as windproof brakes, which only play a certain role when the wind force is small. When encountering a typhoon, the rail clamp will inevitably slip and cannot be increased. Force self-locking, so that the gantry crane slides on the track, and the braking effect is poor
