[0002] A railway switch is a line connection device that enables a locomotive and rolling stock to transfer from one track to another. The switch is an important device for realizing track conversion and is widely present on railway lines. The switch consists of three units: a point mechanism, a connecting part, and a frog and guard rail. The point mechanism includes stock rails, switch rails, and a point machine. The switch realizes the conversion of the route of the locomotive and rolling stock by changing the opening and closing direction of the switch rail. At present, electro-hydraulic controlled automatic switches have replaced the backward manual switches, and the switch operator can remotely control the opening and closing of multiple groups of switches through a microcomputer interlocking. Due to the large number of joints and complex curves in the switch area, railway switch failures occur frequently, especially the electrical and mechanical failures of the switch point mechanism occur at a relatively high frequency. When a switch maintenance worker performs maintenance and repair on an automatic switch on-site, sometimes the hands or feet of the maintenance personnel will enter the action area between the switch rail and the stock rail for maintenance operations. If the remote switch operator misoperates at this time, the hands or feet of the switch maintenance personnel will be pinched and a personal injury accident will occur. Summary of the Utility Model

The base groove has a door frame type structure and is composed of a base groove top plate and base groove outer side plates and base groove inner side plates respectively connected to both ends thereof, and the opening faces downward. The protection groove is located outside the base groove inner side plate and is composed of a protection groove top plate and a protection groove outer side plate with the opening facing downward. One end of the protection groove top plate is vertically connected to the outside of the base groove inner side plate, and the other end is vertically connected to the top end of the protection groove outer side plate. A handle is connected to the middle position of the base groove top plate.

[0005] Further, the handle is in a "T" shape, and its straight rod is perpendicular to the base groove top plate surface.

[0006] Further, the opening width and height of the base groove are slightly larger than the width and height of the switch stock rail.

[0007] Further, the width of the protection groove is smaller than the distance between the switch stock rail and the switch rail in the separated state.

[0008] Further, the length of the base groove outer side plate is shorter than the length of the base groove inner side plate.

[0009] Further, the length of the outer side plate of the base groove is either half of the length of the inner side plate of the base groove.

[0010] By using the stock rail of the switch as the base and setting up a stable and reliable safety protection device in the action area of the switch point rail and the stock rail of the railway automatic switch, the present utility model solves the problem that the switch maintenance personnel may be injured by the switch point rail when maintaining the switch, providing safety guarantee for the switch maintenance personnel during operation.
