Problems solved by technology

[0002] Most of the current train tracks are fixedly installed on the sleepers through the threaded connection of bolts and nuts. However, because the train will vibrate when running on the track, most of the present bolts and nuts do not have self-locking structures, resulting in nuts and bolts. Looseness often occurs, and when the bolts and nuts are loose, it is difficult to detect, and there is no reminder device, so we propose a train track fixing device that can be self-locking and easy to confirm whether it is loose to solve the above problems

Abstract

A fixing device for a train track that can be self-locked and is easy to confirm whether it is loose, including bolts, self-locking grooves, barb 1, mounting nuts, springs, push rods, fixing nuts, clamping blocks, barb 2, lower jacking blocks, Upper top block, fixed nail, alarm ring, movable block 1, ring pipe and movable block 2, self-locking grooves are provided around the bolt, the inner wall of the self-locking groove is fixedly connected with barb 1, and the outer thread of the bolt is connected with The fixed nut, the inner bottom wall of the fixed nut is fixedly connected with two barbs. This self-locking and easy to confirm whether the train rail fixing device is loose is used through the cooperation of the push rod and the clamping block. After the fixing nut is tightened, the push rod is pushed to make the clamping block protrude from the fixing nut and align with the barb. The snap connection makes the fixing nut and the bolt relatively fixed, thereby achieving the effect of self-locking, thereby effectively preventing the fixing device from loosening due to vibration and improving the safety of the track.

Description

technical field [0001] The invention relates to the technical field of a fixing device for a train track, in particular to a fixing device for a train track that can be self-locked and is easy to confirm whether it is loose. Background technique [0002] Most of the current train tracks are fixedly installed on the sleepers through the threaded connection of bolts and nuts. However, because the train will vibrate when running on the track, most of the present bolts and nuts do not have self-locking structures, resulting in nuts and bolts. Loosening often occurs, and when the bolts and nuts are loose, it is difficult to detect, and there is no reminder device. Therefore, we propose a train track fixing device that can be self-locked and is easy to confirm whether it is loose to solve the above problems. Contents of the invention [0003] The present invention adopts the following technical solutions to achieve the technical purpose: a train rail fixing device that can be se...
