Description

Technical Field

[0001] The utility model belongs to the technical field of crane hoisting equipment, and in particular relates to an anti-sway device for a power-exchanging hoisting equipment. Background Art

[0002] A hoist refers to a device used in lifting machinery to lift heavy objects. The most commonly used hoists for lifting finished items are hooks and slings. Others include lifting rings, lifting suction cups, clamps, and forks. Battery swap stations generally use hoists to replace batteries. Existing hoists are generally driven by steel wire ropes to achieve lifting and lowering. When the hoist descends to contact the battery box, the shaking of the steel wire rope will affect the fixing effect between the hoist and the battery box. After the hoist and the battery box are fixed, the battery box will also shake during the process of moving the battery box. On the one hand, it affects the installation accuracy between the battery box and the electric vehicle; on the other hand, it may damage the parts in the battery box. Therefore, when the existing hoist is lifting the battery box, it is easy to have a strong swing, which can easily damage the parts in the battery box. Utility Model Content

[0003] In order to solve the technical problem that the existing battery replacement hanger is prone to strong swing, the utility model provides an anti-sway device for the battery replacement hanger, including a horizontally arranged support beam, and two symmetrically arranged movable pulley assemblies are arranged at the top of the support beam. When in use, the wire rope passes through the movable pulley assembly and is connected to the lifting mechanism of the crane. The wire rope pulls the movable pulley assembly to move upward, and the two movable pulley assemblies are assembled at both ends of the support beam. A horizontally arranged upper hanger is arranged below the support beam, and a lifting lug is arranged at the top of the upper hanger. Four symmetrically arranged connecting rods are arranged between the upper hanger and the support beam. The top ends of the four connecting rods are hinged to the bottom end of the support beam, and the bottom ends of the connecting rods are respectively hinged to the four corners of the top end of the upper hanger. A horizontally arranged lower hanger is arranged below the upper hanger, and four connecting columns with adjustable lengths and distributed in a spatial rectangle are arranged between the lower hanger and the upper hanger. A plurality of hooks are fixed to the bottom end of the lower hanger. The connecting column includes a vertically arranged support tube, the top end of the support tube is fixed to the bottom of the support beam, the lower end of the support tube is sleeved with a vertically arranged column, the bottom end of the column is fixed to the top of the lower hanger, and the column and the support tube are detachably fixedly connected. According to needs, the distance between the upper hanger and the lower hanger can be adjusted by adjusting the height of the connecting column, so that the distance from the movable pulley assembly to the crane lifting mechanism is the shortest, thereby minimizing the swing of the wire rope.

[0004] Preferably, the support beam is a rectangular frame structure, and a plurality of fixing rods are provided inside the support beam.

[0005] Preferably, the support tube and the column are both provided with a plurality of evenly spaced fixing holes from top to bottom, and pins are provided in the fixing holes.

[0006] Preferably, the length of the upper hanger is longer than the length of the support beam.

[0007] Preferably, a plurality of support rods for stabilizing the structure are provided on the lower hanger.

[0008] The above solution has the following advantages:

[0009] The setting of the support beam and the movable pulley assembly plays the role of connecting with the crane hoisting mechanism; the setting of the upper hanger and the connecting rod can increase the spatial volume of the upper hanger and the support beam, and can increase the center of gravity of the support beam and the upper hanger, so that the overall center of gravity of the sling is improved and the swing of the wire rope is reduced; the setting of the connecting column can minimize the distance from the movable pulley assembly to the crane hoisting mechanism by adjusting the distance between the upper hanger and the lower hanger, thereby minimizing the swing of the wire rope.

[0013] like Figure 1-2As shown, an anti-sway device for a battery-exchange hanger comprises a horizontally arranged support beam 1, and two symmetrically arranged movable pulley assemblies 11 are arranged at the top of the support beam 1. When in use, a steel wire rope passes through the movable pulley assembly 11 and is connected to the lifting mechanism of the crane. The steel wire rope pulls the movable pulley assembly 11 to move upward, and the two movable pulley assemblies 11 are assembled at both ends of the support beam 1. A horizontally arranged upper hanger 2 is arranged below the support beam 1, and a lifting lug 21 is arranged at the top of the upper hanger 2. Four symmetrically arranged connecting rods 22 are arranged between the upper hanger 2 and the support beam 1. The top ends of the four connecting rods 22 are hinged at the bottom end of the support beam 1, and the bottom ends of the connecting rods 22 are respectively hinged at the four corners of the top end of the upper hanger 2. A horizontally arranged lower hanger 3 is arranged below the upper hanger 2, and four connecting columns 4 with adjustable lengths and distributed in a spatial rectangle are arranged between the lower hanger 3 and the upper hanger 2. A plurality of hooks 31 are fixed at the bottom end of the lower hanger 3. The connecting column 4 includes a vertically arranged support tube 41, the top end of the support tube 41 is fixed to the bottom of the support beam 1, the lower end of the support tube 41 is sleeved with a vertically arranged column 42, the bottom end of the column 42 is fixed to the top of the lower hanger 3, and the column 42 and the support tube 41 are detachably fixedly connected.
