[0030] Embodiment

[0031] As Figure 1 and Figure 2 As shown, a safety steering device for a rail-mounted crane proposed by the present utility model includes a moving mechanism 2 installed on a rail 1. The bottom of the moving mechanism 2 is used to install a hoisting device and drive it to move. The rail 1 is in an "I"-shaped structure. The moving mechanism 2 includes side plates 21 and a mounting frame 22. The two groups of side plates 21 are symmetrically arranged on both sides of the rail 1. The mounting frame 22 is fixedly connected to the bottoms of the two groups of side plates 21, and the mounting frame 22 keeps the distance between the two groups of side plates 21 fixed. The mounting frame 22 is arranged below the side plates 21, and the hoisting device is installed on the mounting frame 22, which is used to drive the hoisting device to move when the moving mechanism 2 moves. At the same time, a locking module should also be installed on the mounting frame 22 to facilitate positioning after moving to a specified position. The moving mechanism 2 further includes a rotating rod 23, a top wheel 24, a positioning seat 25, and a servo motor 26. The two groups of rotating rods 23 are respectively rotatably connected to the two groups of side plates 21. The top wheel 24 is fixedly connected to the rotating rod 23, so that the top wheel 24 rotates in place. At the same time, there is a certain distance between the side plates 21 and the rail 1 to prevent the side plates 21 from contacting the rail 1 when moving to a curved position of the rail 1. The positioning seat 25 is rotatably connected to the rotating rod 23, and the positioning seat 25 is fixedly connected to the side plates 21, which is used to improve the stability of the rotating rod 23 when rotating. The servo motor 26 is installed on one side of the side plates 21. The output end of the servo motor 26 penetrates the side plates 21 and is fixedly connected to a group of rotating rods 23. The servo motor 26 is used to drive the rotating rod 23 and the top wheel 24 to rotate after starting, so that the side plates 21 and the mounting frame 22 can move.

[0032] Furthermore, please refer to Figures 2-4, the above-mentioned safety steering device includes two groups of limit components 3 symmetrically arranged on both sides of the track 1. The limit components 3 are used to reduce the friction when the mounting frame 22 moves. The limit components 3 include limit blocks 31 and balls 32. Five groups of limit blocks 31 are arranged at equal intervals, and ten groups of balls 32 are evenly arranged in the five groups of limit blocks 31. Two groups of balls 32 are respectively arranged in each group of limit blocks 31, and both groups of balls 32 are in contact with the track 1, which is convenient for applying friction during movement and improving the smoothness of movement. The limit components 3 further include slide rods 33, limit discs 34, springs 35, and synchronous plates 36. The slide rods 33 are fixedly connected to the side of the limit blocks 31 away from the track 1, and the limit discs 34 are fixedly connected to the ends of the slide rods 33 away from the limit blocks 31 to prevent the slide rods 33 from detaching from the synchronous plates 36. The synchronous plates 36 are slidably connected to the five groups of slide rods 33. The slide rods 33 are arranged in a quadrangular prism shape to prevent the slide rods 33 from rotating, thereby preventing the limit blocks 31 from rotating. The synchronous plates 36 are fixedly connected to the bottom of the side plates 21, and the side plates 21 and the synchronous plates 36 move synchronously. The five groups of springs 35 are all arranged between the limit blocks 31 and the synchronous plates 36, and the five groups of springs 35 are respectively sleeved on the outer circles of the five groups of slide rods 33. When moving to the bending position, the springs 35 release elastic force, so that the balls 32 mounted on the limit blocks 31 can always be tightly attached to the track 1.

[0033] Furthermore, the above-mentioned safety steering device further includes two groups of adjustment components 4. The adjustment components 4 are used to drive the moving mechanism 2 to rotate and cooperate with the turning position of the track 1. The adjustment components 4 include mounting plates 41, push rod motors 42, first connecting rods 43, and first rollers 44. The two groups of mounting plates 41 are symmetrically arranged on both sides of the side plates 21. The push rod motors 42 are installed on the sides of the mounting plates 41 away from the track 1. The output ends of the push rod motors 42 penetrate through the mounting plates 41 and are fixedly connected to the first connecting rods 43. The first rollers 44 are installed at the ends of the first connecting rods 43 away from the push rod motors 42. After the push rod motors 42 are started, the distance between the mounting plates 41 and the track 1 is adjusted. Thus, after adjusting the four groups of mounting plates 41, the side plates 21 can be tilted to facilitate passing through the bending position of the track 1. The adjustment components 4 further include second connecting rods 45 and second rollers 46. The second connecting rods 45 are arranged on the side of the track 1. One end of the second connecting rods 45 is fixedly connected to the side plates 21, and the second rollers 46 are installed at the ends of the second connecting rods 45 close to the track 1 for supporting.

[0034] In this embodiment, after the servo motor 26 is started, the rotating rod 23 drives the top wheel 24 to rotate, driving the side plate 21 to move. Since the two side plates 21 are fixedly connected together through the mounting frame 22, the two side plates 21 move synchronously. When the side plate 21 moves, the two sets of balls 32 in the limit block 31 contact the track 1, so that when the side plate 21 moves, the friction can be reduced while preventing the side plate 21 and the mounting frame 22 from detaching from the track 1, thus ensuring safety. At the same time, when moving to the bent position of the track 1, the two push rod motors 42 extend and the two push rod motors 42 shorten, driving the side plate 21 and the mounting frame 22 to tilt. At the same time, the five springs 35 are compressed to different degrees, ensuring the close contact between the push rod motor 42 and the track 1, facilitating smooth passage when moving to the bent position, with high smoothness during movement and ensuring high safety.

[0035] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
