The installation grooves 1 The top of the inner cavity of the first sleeve 160 is fixedly connected to the first sleeve 160, and the inner cavity of the first sleeve 160 is slidably connected to the second sleeve 170. The first elastic member 180 is fixedly connected between the top of the inner cavity of the first sleeve 160 and the bottom of the inner cavity of the second sleeve 170. The first sleeve 160 is used to cooperate with the second sleeve 170 and the first elastic member 180 to drive the push plate 190 to be in close contact with the inner wall of the slide groove 110 after entering the internal slope of the slide groove 110. The top of the second sleeve 170 is fixedly connected to the push plate 190. The push plate 190 is used to slow down the moving speed of the crane body 120 by friction generated by contact with the inner wall of the slide groove 110. The traveling beam 100 is used to support the positioning plate 200.

[0027] Please refer again Figure 1-4 The third sleeve 230 is fixedly connected to the upper and lower sides of the inner wall of the positioning plate 200, and the fourth sleeve 240 is slidably connected to the outer wall of the third sleeve 230. The second elastic member 250 is fixedly connected between the inner wall of the third sleeve 230 and the inner wall of the fourth sleeve 240. The third sleeve 230 is used to cooperate with the fourth sleeve 240 and the second elastic member 250 to buffer the impact on the first limit plate 260. The positioning plate 200 is fixedly connected to the left and right side walls of the traveling beam 100, and the positioning plate 200 is used to support the third sleeve 230.

[0028] Please refer again Figure 1-4 The left and right side walls of the crane body 120 are fixedly connected with a first guard plate 121, and the left and right side walls of the top plate 130 are fixedly connected with a second guard plate 131. The first guard plate 121 and the second guard plate 131 can be closed to protect the crane body 120 and the top plate 130.

[0029] Please refer again Figure 1-4 The bottom of the push plate 190 is fixedly connected with an anti-skid pad 191, and the anti-skid pad 191 is made of rubber material. The anti-skid pad 191 made of rubber material has high anti-skid performance.

[0030] Please refer again Figure 1-4The outer wall of the positioning plate 200 is fixedly connected with a support block 210, and the outer wall of the support block 210 is fixedly connected with a mounting plate 220. The support block 210 cooperates with the mounting plate 220 to provide space for the support rod 270 to move under force.

[0031] Please refer again Figure 1-4 The end of the fourth sleeve 240 is fixedly connected to the first limit plate 260, and the upper and lower sides of the outer wall of the first limit plate 260 are fixedly connected to the support rod 270, and the support rod 270 passes through the inner wall of the positioning plate 200 and extends to the outside of the positioning plate 200. The support rod 270 cooperates with the first limit plate 260 and the positioning plate 200 to maintain the stability of the fourth sleeve 240 after being contracted by force.

[0032] Please refer again Figure 1-4 A second limiting plate 280 is fixedly connected between the ends of the support rod 270. The first limiting plate 260 and the second limiting plate 280 are both made of stainless steel. The first limiting plate 260 and the second limiting plate 280 made of stainless steel have high strength and corrosion resistance.

[0033] To summarize, the force generated by the first guard plate 121 and the second guard plate 131 hitting the first limit plate 260 is buffered by multiple third sleeves 230 cooperating with the fourth sleeve 240 and the second elastic member 250, and then the crane body 120 drives the top plate 130 to drive the slider 140 to slide inside the slide groove 110. At the same time, when the push plate 190 moves to the slope of the slide groove 110, the first sleeve 160 cooperates with the second sleeve 170 and the first elastic member 180 to drive the push plate 190 to carry the anti-slip pad 191 and make close contact with the inner wall of the slide groove 110, thereby decelerating the movement of the crane body 120, thereby reducing the impact force of the crane body 120 with the positioning plate 200, so that it has high anti-collision buffering performance, which is convenient for providing deceleration when the crane runs to the side end, has high anti-collision performance, improves the anti-collision ability of the crane, and improves the use efficiency of the anti-collision device of the lifting equipment.

[0034] In specific use, the technical personnel in this field first start the crane body 120 to operate, and the crane body 120 starts to move to the left. Then, the crane body 120 drives the top plate 130 to drive the slider 140 to move to the left in the slide groove 110. When the push plate 190 encounters the internal slope of the slide groove 110, the left push plate 190 contacts the bottom of the inner wall of the slide groove 110. In the process of the crane body 120 continuing to move to the left, the pressure of the push plate 190 contacting the bottom of the inner wall of the slide groove 110 drives the first elastic member 180 to start to contract, and the rebound force generated by the contraction of the first elastic member 180 cooperates with the rebound force generated by the contraction of the first elastic member 180. The second sleeve 170 pushes the push plate 190 to contact more closely with the bottom of the inner wall of the slide groove 110, thereby slowing down the movement speed of the crane body 120 to the left end of the traveling beam 100 through the friction between the push plate 190 and the inner wall of the slide groove 110, thereby reducing the impact force between the crane body 120 and the positioning plate 200, and respectively contacts the lower first limit plate 260 and the upper first limit plate 260 through the first guard plate 121 and the second guard plate 131, driving the upper and lower third sleeves 230 on the left side and the fourth sleeve 240 and the second elastic member 250 to cooperate with each other to buffer the impact of the crane body 120.
