[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 3 As shown, a quay crane crane anti-falling box device described in an embodiment of the utility model comprises a crane body 1; two fixing plates 11 are fixedly connected to the side wall of the crane body 1, and the two fixing plates 11 are arranged oppositely. A hydraulic cylinder 12 is fixedly connected to the top of the fixing plate 11, and a first connecting rod 13 is fixedly connected to the end of the hydraulic cylinder 12, and a shift rod 14 is fixedly connected to the end of the first connecting rod 13, and the middle part of the shift rod 14 passes through the middle part of the fixing plate 11, and the shift rod 14 is slidably connected in the middle part of the fixing plate 11, and a first sliding rod 15 is slidably connected to the middle part of the shift rod 14, and the first sliding rod 15 is arranged at an end away from the first connecting rod 13, and a first spring 16 is fixedly connected between one end of the first sliding rod 15 and the shift rod 14. When working, the container is fixed to the bottom of the crane body 1, and the container is lifted by a crane. The connected shift rod 14 is slid downward by opening the hydraulic cylinder 12. When the shift rod 14 moves downward When the container is lifted up, the two gear bars 14 are in a state of being pulled back and forth, so that the lifting device 10 can lift the container and the lifting device 10 can move upwards and downwards, thereby preventing the lifting device 10 from sliding off the lifting device 10 and causing the lifting device 10 to move downwards.

[0025] like Figure 1 , Figure 3 , Figure 4 As shown, the first slide bar 15 is fixedly connected to a support seat 2 at one end away from the first spring 16, a through slot 25 is opened in the middle of the support seat 2, a support rod 21 is fixedly connected to the side wall of the support seat 2, a motor 22 is fixedly connected to the end of the support rod 21, a take-up wheel 23 is fixedly connected to the output end of the motor 22, and the take-up wheel 23 is arranged in the middle of the through slot 25. During operation, after the container is fixed on the spreader body 1, the motor 22 is turned on during the downward movement of the shift rod 14 to rotate the end of the motor 22, and at the same time drive the take-up wheel 23 to rotate, and the wire rope 24 is released. When the first slide bar 15 moves to the bottom of the container, the two sides of the container are tightened and supported by the two wire ropes 24. When the container is unloaded, , turn on the motor 22 again, change the rotation direction of the motor 22, tighten the wire rope 24 inside the take-up wheel 23, and as the wire rope 24 is tightened and shortened, the first slide bar 15 slides in the direction of the first spring 16, so that the container can be loaded and unloaded. The wire rope 24 can effectively support both sides of the container during the loading and unloading process, and can effectively provide support for the container. The wire rope 24 can effectively increase the balance and stability of the container during the loading and unloading process, effectively reduce the risk of falling caused by shaking or tilting of the container during the movement of the container, effectively reduce the risk of damage or surface scratches caused by the shaking of the container and collision with other objects, and effectively improve the efficiency of container loading and unloading.

[0026] like Figure 1 and Figure 4 As shown, two support plates 3 are fixedly connected to the side walls of the support seat 2, and the two support plates 3 are arranged opposite to each other. The ends of the support plates 3 are fixedly connected to a base 31, and the middle part of the base 31 is rotatably connected to a pulley 32. During operation, when the first slide bar 15 moves to the bottom of the container, it contacts the surface of the container through the pulley 32, and rotates after contacting the surface of the container. The pulley 32 can effectively make the first slide bar 15 move more smoothly on the contact surface of the container, effectively reduce the friction with the surface of the container, can effectively reduce the wear caused by the friction of the container surface, and can provide certain support to the container, effectively increasing the overall stability of the container.

[0027] like Figure 3As shown, a second connecting rod 4 is fixedly connected to the middle part of the support seat 2, and the second connecting rod 4 is arranged inside the through groove 25. The side wall of the second connecting rod 4 is fixedly connected to multiple groups of bristles 41. During operation, when the wire rope 24 is collecting or releasing, the bristles 41 contact the surface of the wire rope 24 to clean the dust and impurities on the surface of the wire rope 24. The bristles 41 can effectively reduce the dust and impurities on the surface of the wire rope 24 when it is being collected and released, and effectively reduce the accumulation of dust and impurities on the surface of the wire rope 24 due to long-term use, effectively reduce the wear and corrosion problems caused by dust and impurities on the surface of the wire rope 24, and can effectively reduce the friction and wear caused by the accumulation of dust and impurities on the surface of the wire rope 24 after contact with the container, thereby effectively increasing the safety performance of the wire rope 24.

[0028] like Figure 1 and Figure 5 As shown, two electric push rods 5 are fixedly connected to the side wall of the spreader body 1, and the two electric push rods 5 are arranged opposite to each other. The two electric push rods 5 are fixedly connected to the middle part of the spreader body 1, and the ends of the electric push rods 5 are fixedly connected to a fixing frame 51, and the ends of the fixing frame 51 are fixedly connected to a first elastic plate 52. When working, the electric push rod 5 is opened and moved outward, and the container is fixed and moved through the bottom of the spreader body 1, and then the electric push rod 5 is retracted and moved, so that the first elastic plate 52 is tightly fitted with both sides of the container, and the first elastic plate 52 is squeezed and elastically bent when it contacts the surface of the container when the electric push rod 5 is retracted to clamp the container. The elastic bending of the first elastic plate 52 can effectively increase the contact area with the container, and the extension and retraction of the electric push rod 5 can effectively adapt to containers of different sizes, and the clamping of the container can effectively reduce the sliding or overturning of the container caused by the wind, effectively reduce the risk of the container falling due to shaking during loading and unloading, and effectively improve the safety and stability of the container loading and unloading process.

[0029] like Figure 1 and Figure 5 As shown, two second sliding bars 6 are slidably connected to the middle part of the first elastic plate 52, and a fixing frame 51 is fixedly connected between the end of the second sliding bar 6 and the first elastic plate 52, and a suction cup 62 is fixedly connected to the end of the second sliding bar 6 away from the second spring 61. During operation, when the first elastic plate 52 fits the container, the suction cup 62 contacts the surface of the container. When the suction cup 62 contacts the container, it is squeezed so that the suction cup 62 is sucked on the surface of the container, and when it is under pressure, it slides in the middle part of the first elastic plate 52 through the second sliding bar 6. When the container is unloaded, the second sliding bar 6 is elastically reset by the second spring 61. By having multiple groups of suction cups 62 adsorbed on the container, the damage caused when the container is clamped and fixed can be reduced, and the adsorption force of the suction cup 62 can increase the firmness of the first elastic plate 52 to the container, so that it can be quickly adsorbed on the surface of the container, and the maintenance cost can be effectively reduced.

[0030] like Figure 1 As shown, a second elastic plate 7 is fixedly connected to the middle part of the first sliding rod 15, and the second elastic plate 7 is fixedly connected to one end close to the support seat 2. When working, the container is supported during loading and unloading by the second elastic plate 7, and elastically bends when subjected to the pressure of the container. The second elastic plate 7 can effectively increase the supporting force for the container, effectively disperse a certain side weight, and increase a certain buffering force through elasticity, effectively reducing the vibration of the container caused by the collision of external force. Reducing the vibration of the container can effectively increase the stability of the container.

[0031] When working, the container is fixed at the bottom of the spreader body 1, and the container is lifted by the crane. The connected gear rod 14 is slid downward by opening the hydraulic cylinder 12. When the gear rod 14 moves downward, the end of the first slide bar 15 contacts the container and is squeezed by the container. The first spring 16 is squeezed and elastically stretched to make the first slide bar 15 slide in the middle of the gear rod 14. When the first slide bar 15 moves to the bottom of the container, the first spring 16 elastically contracts to reset the first slide bar 15. When the container is fixed to the spreader body, the first slide bar 15 is pressed and elastically stretched to make the first slide bar 15 slide in the middle of the gear rod 14 ... After the container is mounted on the container body 1, the motor 22 is turned on during the downward movement of the gear lever 14 to rotate the end of the motor 22, and the take-up wheel 23 is driven to rotate, and the wire rope 24 is released. When the first slide bar 15 moves to the bottom of the container, the two sides of the container are tightened and supported by the two wire ropes 24. When the container is unloaded, the motor 22 is turned on again, the rotation direction of the motor 22 is changed, and the wire rope 24 is tightened inside the take-up wheel 23. As the wire rope 24 is tightened and shortened, the first slide bar 15 moves toward the first spring 16, so as to load and unload the container. When the first slide bar 15 moves to the bottom of the container, it contacts the surface of the container through the pulley 32, and then rotates after the pulley 32 contacts the surface of the container. When the wire rope 24 is collecting or releasing, the brush 41 contacts the surface of the wire rope 24 to clean the dust and impurities on the surface of the wire rope 24. The electric push rod 5 is opened and moved outward, and the container is fixed and moved through the bottom of the sling body 1, and then the electric push rod 5 is retracted and moved, so that the first elastic plate 52 is in contact with the first elastic plate 52. The two sides of the container are tightly fitted, and when the electric push rod 5 contracts, the first elastic plate 52 is squeezed and elastically bent when it contacts the surface of the container to clamp the container. When the first elastic plate 52 fits the container, it contacts the surface of the container through the suction cup 62. When the suction cup 62 contacts the container, it is squeezed so that the suction cup 62 is sucked on the surface of the container. When it is under pressure, the second slide bar 6 slides in the middle of the first elastic plate 52, and the second elastic plate 7 supports the container during loading and unloading, and elastically bends when it is under pressure from the container.
