[0029] The interior of the steel plate beam 1 is hollow, the sliding plate 12 is located inside the steel plate beam 1, and the outer walls of the sliding plate 12 are slidably connected to the inner walls of the steel plate beam 1;

[0030] The buffer mechanism includes a telescopic rod 14, a spring 15 arranged on the outer wall of the telescopic rod 14, a fixed frame 7 arranged at the bottom of the sliding plate 12, a rotating disk 8 arranged between the inner walls on both sides of the fixed frame 7, two fixed columns 5 arranged at the bottom of the sliding plate 12, and the same steel rope 6 arranged at one end of the two fixed columns 5.

[0031] The top of the telescopic rod 14 is fixedly connected to the bottom of the sliding plate 12, the bottom of the telescopic rod 14 is fixedly connected to the bottom inner wall of the steel plate beam 1, one end of the spring 15 is fixedly connected to the bottom of the sliding plate 12, the bottom of the spring 15 is fixedly connected to the bottom inner wall of the steel plate beam 1, and the spring 15 is sleeved on the outside of the telescopic rod 14;

[0032] The bottom of the steel plate crossbeam 1 is fixedly connected to the top of the fixed frame 7, a plurality of through holes 9 are provided on the bottom inner wall of the steel plate crossbeam 1, and the fixed frame 7 is slidably connected to the plurality of through holes 9, a rotating disk 8 is rotatably connected between the inner walls on both sides of the fixed frame 7, a through groove 10 is provided on the bottom inner wall of the steel plate crossbeam 1, and the rotating disk 8 is located in the through groove 10 and slidably connected; the tops of the two fixed columns 5 are fixedly connected to the bottom of the sliding plate 12, the circumferential outer walls of the fixed columns 5 are fixedly connected with reinforcement blocks 13, the tops of the reinforcement blocks 13 are fixedly connected to the bottom of the sliding plate 12, two penetrating sliding holes 11 are provided on the bottom inner wall of the steel plate crossbeam 1, and the two fixed columns 5 are slidably connected to the two sliding holes 11 respectively.

[0033] It should be noted that by arranging the sliding plate 12, telescopic rod 14, spring 15 and fixed column 5 in the steel plate cross beam 1, the dead weight and usable volume of the device body can be reduced, the carrying capacity of the crane can be increased, the inertia force can be reduced, which is beneficial to the dynamic response of the crane. The reduction in volume and weight can speed up the response speed of the lifting system, improve the control accuracy, and reduce the raw materials and processing, and reduce the manufacturing and maintenance costs. By arranging the sliding plate 12 in the steel plate cross beam 1, through the cooperation of the telescopic rod 14 and the spring 15 in the sliding plate 12, the swinging movement of the hook 4 can be suppressed and reduced when the hook 4 is lifting goods, so that the lifting of heavy objects is more stable and the risk of accidental falling is reduced. In addition, the working ability of the crane under wind and wave conditions is improved, so that it can remain stable under large wind and wave operating conditions, and the adaptability to the use environment is broadened.

By arranging the components in the steel plate cross beam 1, the dead weight of the device body can be reduced and the Using volume can increase the load-bearing capacity of the crane and reduce the inertia force, which is beneficial to the dynamic response of the crane. The reduction in volume and weight can speed up the response speed of the lifting system and improve the control accuracy. In addition, it can reduce raw materials and processing, and can reduce manufacturing and maintenance costs. When the sliding plate 12 moves, the fixed column 5 and the fixed frame 7 move synchronously. Since the steel rope 6 is located in the groove 16 on the outer wall of the circumference of the rotating disk 8, when the hook 4 swings, the rotating disk 8 moves up and down on the steel rope 6, which suppresses the hook 4 from swinging left and right when hanging goods, and can prevent the steel rope 6 from being subjected to excessive tension, thereby improving the safety and stability of the system.
