[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] like Figure 1-4 As shown, a movable protective device for a ladle straddle car comprises a straddle car 1, a plurality of protective plates 2 are hinged on both sides of the straddle car 1, a plurality of support rods 3 are hinged on the outer sides of the protective plates 2, a positioning rod 4 is hinged at the middle position of the support rod 3, the other end of the positioning rod 4 is hinged on the protective plate 2, a plurality of latches 5 are inserted on the inner side of the protective plate 2, and the bottom ends of the latches 5 are inserted into the straddle car 1.

[0022] The protection plate 2 is linearly distributed on both sides of the straddle vehicle 1, the top end of the support rod 3 is hinged at the upper outer side of the protection plate 2, a hollow 6 is provided on the support rod 3, and strip holes 7 are opened on both sides of the bottom end of the hollow 6 of the support rod 3, and the strip holes 7 are connected to the hollow 6. The hollow 6 of the support rod 3 can accommodate the strip hole 7.

[0023] The positioning rod 4 is located in the hollow 6 of the support rod 3. A pin 8 is welded on both sides of one end of the positioning rod 4. The two pins 8 are respectively connected to the strip holes 7 on both sides of the support rod 3 at the hollow 6. The positioning rod 4 is hinged to the support rod 3 through the strip holes 7 and the pins 8. During the unfolding process, the free end of the support rod 3 hinged on the protective plate 2 rotates downward, driving the positioning rod 4 to rotate and the pin 8 to slide in the strip hole 7. When the pin 8 slides to the end of the strip hole 7, the support rod 3 and the positioning rod 4 stop rotating. During the manufacturing process, the length of the support rod 3, the positioning rod 4 and the length of the strip hole 7 are controlled so that the support rod 3 is in a horizontal state when the protective plate 2 is unfolded, and at this time, one end of the support rod 3 is against the protective plate 2, thereby supporting the protective plate 2. After the protective plate 2 is folded, the support rod 3 and the positioning rod 4 return to the hollow 6 under their own weight, thereby reducing the width of the straddle car 1.

[0024] The latch pin 5 is L-shaped, and a baffle plate 9 is welded to the latch pin 5 .

[0025] The latch pin 5 is plugged into two fixing plates 11 welded to the inner side of the protection plate 2 , and the baffle plate 9 is located between the two fixing plates 11 .

[0026] A plurality of insertion holes 10 are provided on the straddle carrier 1 . The positions of the insertion holes 10 correspond to the positions of the latch pins 5 . The bottom ends of the latch pins 5 are plugged into the insertion holes 10 of the straddle carrier 1 .

[0027] The working principle of the utility model is:

[0028] When in use, the protective plate 2 hinged on both sides of the cross-carriage 1 is unfolded to both sides. During the unfolding process, the free end of the support rod 3 hinged on the protective plate 2 rotates downward, driving the positioning rod 4 to rotate and the pin shaft 8 to slide in the strip hole 7. When the pin shaft 8 slides to the end of the strip hole 7, the support rod 3 and the positioning rod 4 stop rotating. During production, the length of the support rod 3, the positioning rod 4 and the length of the strip hole 7 are controlled so that the support rod 3 is in a horizontal state when the protective plate 2 is unfolded, and at this time, one end of the support rod 3 is against the protective plate 2, thereby supporting the protective plate 2. The latch 5 will also slide on the fixed plate 11. When the baffle 9 contacts the fixed plate 11, it prevents the latch 5 from continuing to slide down, thereby preventing the latch 5 from falling out of the fixed plate 11. After the protective plate 2 is unfolded, it can protect the equipment on both sides of the cross-carriage 1 to prevent the steel slag dropped during the loading and unloading process from falling into the equipment.

[0029] After loading and unloading, the protective plate 2 is lifted up until it stands vertically on both sides of the straddle carrier 1. At this time, the support rod 3 and the positioning rod 4 return to the hollow 6 under their own weight, and the latch 5 is lifted up and inserted into the socket 10 to fix the protective plate 2. After the protective plate 2 is folded up, the width of the straddle carrier 1 can be effectively reduced to prevent scratching other equipment, pipelines, and personnel during transportation, thereby improving safety.

[0030] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0031] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
