[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a clean crane lifting anti-collision protection device, comprising a crossbeam 1, columns 2 are fixedly provided on both sides of the lower end of the crossbeam 1, and a lifting mechanism for lifting goods is provided on the outer surface of the crossbeam 1. The lifting mechanism includes a movable frame 3, rollers 4, a motor 5, a first electric hoist 6, and a first hook 7. The outer surface of the lower end of the crossbeam 1 is movably engaged with a movable frame 3, and rollers 4 are movably provided on both sides of the inside of the movable frame 3 through a rotating shaft. A motor 5 is fixedly provided on one side of the surface of the movable frame 3, and the power output shaft end of the motor 5 is transmission-connected with the rotating shaft where the roller 4 is located. A first electric hoist 6 is fixedly provided at the lower end of the movable frame 3, and a first hook 7 is provided at the lower end of the first electric hoist 6. A stabilizing mechanism for stably lifting goods is provided on the surface of the column 2.

[0021] The stabilizing mechanism includes a second electric hoist 8, a connecting rope 9, and a second hook 10. The second electric hoist 8 is fixedly provided on the surface of the column 2. The connecting rope 9 is wound around the outer surface of the second electric hoist 8. The second hook 10 is fixedly provided at one end of the connecting rope 9. The cargo can be further tightened and fixed by the stabilizing mechanism, which can effectively prevent the cargo from being hit due to shaking during transportation.

[0022] A cable 11 is fixedly provided on the surface of the second electric hoist 8, and a controller 12 is fixedly provided at the lower end of the cable 11. The controller 12 is electrically connected to the second electric hoist 8 through the cable 11. The second electric hoist 8 can be conveniently controlled through the controller 12. The extension of the cable 11 makes it convenient for the staff to hold two controllers 12 at the same time and control the two second electric hoists 8 at the same time, which makes it convenient to connect the rope 9 and the second hook 10 to tighten and fix the goods to be lifted.

[0023] A connecting rod 13 is fixedly provided at the lower end of the column 2, and universal wheels 14 are movably provided on both sides of the lower end of the connecting rod 13. The universal wheels 14 can facilitate the movement of the entire pushing device, thereby facilitating the transportation of goods;

[0024] A stabilizing rod 15 is fixedly provided between the connecting rod 13 and the column 2, and the stabilizing rod 15 can ensure the stability between the column 2 and the connecting rod 13;

[0025] The second electric hoist 8 is provided with a fixed frame 16 on its surface, and a fixed pulley 17 is provided on the surface of the fixed frame 16 via a rotating shaft. The fixed pulley 17 is in contact with the connecting rope 9. The fixed pulley 17 can facilitate the movement of the second electric hoist 8 to drive the rope to move, thereby avoiding unnecessary friction loss.

[0026] Working principle: When using this device, the device lifts the goods through the first electric hoist 6 and the first hook 7, so that the goods can be lifted for transportation or loading and unloading conveniently. After the goods are lifted, they are only connected by the first hook 7, and the goods are very easy to shake, so that unnecessary collisions are very likely to occur. At this time, the left and right sides of the goods can be hung by the second hook 10, and then the second electric hoists 8 on the left and right sides are controlled to drive the connecting rope 9 to tighten. In this way, the goods can be tensioned with the first hook 7 through the connecting rope 9 and the second hook 10. In this way, the goods are tensioned and fixed from three points, and the tension of the goods can be further fixed, which can effectively prevent the goods from shaking and causing collisions during lifting and transportation.

[0027] It should be noted that if the lifted cargo has an additional location for hanging the second hook 10, the second hook 10 can be used to hang it directly. If there is no location for hanging the second hook 10, the cargo can be tied up with a rope to artificially increase the hanging location of the second hook 10.
