[0002] A crane is a mechanical device used to lift and move heavy objects. Its main function is to move heavy objects from one location to another through a lifting and moving mechanism.

[0003] The prior art includes a utility model with a publication number of CN220811626U, which discloses a double-beam bridge crane. The utility model includes a main beam, a fixed plate and a fixed cylinder. The two main beams are parallel to each other, and the tops of the two main beams are movably connected to an electric hoist. The lower parts of both ends of the electric hoist are fixed with two limiting plates, and the two limiting plates are respectively arranged on the sides of the two main beams away from each other. The same end of the two main beams is fixed with a walking assembly. The tops of the two walking assemblies are fixed with a fixed plate at the edge of a long side close to the electric hoist, and the side of the fixed plate away from the electric hoist is fixed with a fixed cylinder, and a push piston is movably connected in the fixed cylinder. The utility model solves the problem that the deformation of the two main beams of the double-beam bridge crane easily causes the distance between the two main beams to change, affecting the running stability of the electric hoist, and the electric hoist easily causes the walking assembly to deform when it hits the walking assembly at the end of the main beam.

[0004] The inventor discovered in daily use that a double-beam bridge crane consists of two main beams, a power unit and a lifting hook. The lifting hook is connected to the lifting object, and the lifting hook and the lifting object can be lifted by the power unit. The main beam will drive the power unit to slide along the direction of the main beam, thereby completing the transportation of the lifting object. However, when the lifting hook is only connected to the lifting object, the main beam and the power unit drive the lifting hook and the lifting object. During the lifting and moving process, it was found that the lifting hook and the lifting object will swing on the power unit. When the swing amplitude is large, the lifting object will slip off the lifting hook, thereby causing the lifting object to slip from a high place, causing damage to the surface of the lifting object. There is a greater safety risk of the lifting hook and the lifting object swinging when moving. Utility Model Content

However, in the process of only connecting the lifting hook 6 with the lifting object and driving the lifting hook 6 and the lifting objects to be lifted and moved by the main beam 4 and the power device 5, it is found that the lifting hook 6 and the lifting objects will swing on the power device 5.

[0035] Reference Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment: the auxiliary device 3 includes two adjusting grooves 31, and the two adjusting grooves 31 are both opened on one side of the limiting plate 205. The inner wall of the adjusting groove 31 is slidably connected with a fixing rod 33, one end of the fixing rod 33 is fixedly connected with a sliding plate 32, and the sliding plate 32 is slidably connected to the inner wall of the limiting plate 205. The arc surface of the fixing rod 33 is threadedly connected with a threaded ring 34, and the side of the threaded ring 34 close to the limiting plate 205 is fixedly connected with a friction pad 35. When the limiting plate 205 improves the stability of the hoisted object, when the volume of the hoisted object is large, the auxiliary device 3 can be used to increase the contact area between the limiting and the hoisted object, so that the auxiliary device 3 can be used to improve the contact stability between the limiting plate 205 and the hoisted object. The two sliding plates 32 are fixedly connected to two guide rods 36 on the sides close to each other. Two connecting holes 37 are provided on one side of the inner wall of the limiting plate 205, and two guide rods 36 are slidably connected to the two connecting holes 37 respectively. When the sliding plate 32 slides on the inner wall of the limiting plate 205, the guide rods 36 installed on the sliding plate 32 will slide in the connecting holes 37 provided on the limiting plate 205 as the sliding plate 32 slides, so that the stability of the sliding plate 32 sliding on the inner wall of the limiting plate 205 can be improved by sliding the guide rods 36 in the connecting holes 37. One end of the sliding plate 32 is fixedly connected to a force plate 38, and the cross-section of the force plate 38 is arc-shaped.

[0036] Detailed explanation of usage: When it is necessary to improve the stability of the connection between the hoisted object and the lifting hook 6, first connect the hoisted object to the lifting hook 6, then start the motor 203 on the connecting plate 202, and the movement of the motor 203 can drive the screw 204 to rotate through its output end, and the rotation of the screw 204 can drive the limit plate 205 to move on the screw 204. Because the limit plate 205 is connected to the sliding rod 206, when the screw 204 drives the limit plate 205 to move, the limit plate 205 will move up and down along the direction of the sliding rod 206, so that it can move in the direction of the hoisted object through the limit plate 205, and the limit plate 205 will contact the surface of the hoisted object, so that it can contact the hoisted object through the limit plate 205 to improve the stability of the contact between the hoisted object and the lifting hook 6.

[0037] When it is necessary to increase the contact area between the limit plate 205 and a larger lifting object, slide the sliding plate 32 on the inner wall of the limit plate 205. The sliding of the sliding plate 32 will drive the fixing rod 33 to slide in the adjusting groove 31. Adjust the sliding plate 32 to a suitable position. At this time, the threaded ring 34 can be rotated on the fixing rod 33. The rotation of the threaded ring 34 can drive the friction pad 35 to contact the surface of the limit plate 205, so that the fixing rod 33 can be fixed in the adjusting groove 31, so that the angle of the sliding plate 32 can be fixed. The sliding plate 32 can slide out from the inner wall of the limit plate 205 to increase the contact area between the limit plate 205 and the lifting object.
