[0025] The travel switch structure 2 includes a slide bar 21, a push rod 22, and a spring 23; the slide bar 21 is a hollow structure with an open end, the spring 23 is arranged inside the slide bar 21, the push rod 22 extends from the open end of the slide bar 21 into the slide bar 21 and abuts against the spring 23, and a push block 211 is fixedly connected or integrally formed on the slide bar 21; when the slide bar 21 slides relative to the push rod 22 so that the travel switch mechanism 2 is shortened, the push block 211 moves close to the emergency stop handle 12, thereby controlling the emergency stop switch body 11 to open and the monorail crane to stop moving, and when the slide bar 21 slides relative to the push rod 22 so that the travel switch mechanism 2 is extended, the push block 211 moves away from the emergency stop handle 12, thereby controlling the emergency stop switch body 11 to close.

[0026] In this embodiment, a supporting mechanism 3 is also included, and the supporting mechanism 3 includes a bottom plate 31, a side plate 32, and a fixing buckle 33. The side plate 32 is fixedly connected to one side of the bottom plate 31, and the fixing buckle 33 is fixedly connected to the side plate 32 and is located on a side away from the bottom plate 31. The fixing buckle 33 in the supporting mechanism 3 is connected to the front end of the monorail crane so that the device can be installed on the monorail crane as a whole.

[0027] In this embodiment, the emergency stop switch body 11 is fixedly connected to the top surface of the bottom plate 31 .

[0028] In this embodiment, the push rod 22 is fixedly connected to a side of the side plate 32 away from the fixing buckle 33 , and the front end of the sliding rod 21 is fixedly connected to a front end plate 24 .

[0029] In this embodiment, a pulley mechanism 4 is also included, which includes two pulleys 42 and two parallel fixed plates 41, two fixed rods 43 are fixedly connected between the two fixed plates 41, the pulley 42 is rotatably connected to the fixed rod 43, and the bottom of the fixed plate 41 is fixedly connected to the top of the slide rod 21.
