Description

Technical Field

[0001] The present application relates to the technical field of hoisting devices, and in particular to a hoisting device for a transformer. Background Art

[0002] In the existing transformer installation and maintenance operations, electric hoists are usually used as lifting tools. Although electric hoists are easy to operate, their lifting capacity is often insufficient when facing large transformers and cannot meet the lifting requirements of heavy transformers. In addition, the operation speed of electric hoists is slow, and the stability and safety during the lifting process need to be improved. Utility Model Content

[0003] The problem to be solved by the present application is that when the existing transformer is hoisted by an electric hoist, due to its limited hoisting capacity, it is impossible to stably hoist a large transformer.

[0004] In order to solve the above technical problems, the present application provides a lifting device for a transformer, including a suspension for supporting the transformer in the air, and walking components for walking in an overhead crane or an aerial track are arranged around the suspension. A hanger for connecting with the transformer for lifting operations is arranged directly below the suspension, and a lifting component is arranged between the suspension and the hanger, which uses a pulley block to increase the load-bearing capacity and perform lifting and lowering operations.

[0005] Since the hoisting device of the present application is designed with a walking component and a lifting component, the heavy-load hoisting operation of the transformer can be realized through the lifting component, and the aerial transfer operation of the transformer can be realized through the walking component, which solves the problem that when the transformer of the prior art is hoisted by an electric hoist, the large transformer cannot be stably hoisted due to its limited hoisting capacity.

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0016] The present application relates to a transformer lifting device, such as Figure 1-8 As shown, the hoisting device includes a suspension 2 for supporting in mid-air, and walking components 3 for walking in an overhead crane or an aerial track are arranged around the suspension 2. A hanger 4 for connecting with a transformer for hoisting operations is arranged directly below the suspension 2. In order to improve the hoisting capacity of the hoisting device, a lifting component 1 is arranged between the suspension 2 and the hanger 4, which uses a pulley block to improve the load-bearing capacity and perform hoisting and lifting operations.

[0017] The walking assembly 3 includes a frame 7, a first motor 6, and casters 14. The frame 7 is arranged at the four ends of the suspension 2. The casters 14 for walking are arranged inside the frame 7, and the first motor 6 for driving the casters 14 is arranged on the outside of the frame 7. By driving the casters 14 to rotate through the first motor 6, the suspension 2 can be driven to perform hoisting and moving operations along the overhead crane or the aerial track.

[0018] The lifting assembly 1 includes a second motor 10, a gear box 9, a bobbin 5, a rope, and a pulley. The gear box 9 is arranged in the center of the upper part of the frame. A second motor 10 for power input is arranged at one end of the gear box 9, and a bobbin 5 for power output is symmetrically arranged at the other end of the gear box 9. A rope for traction is wound around the upper part of the bobbin 5, and pulleys abutting against the rope are arranged on the suspension 2 and the hanger 4. The pulleys are divided into fixed pulleys 8 and movable pulleys 11 according to their arrangement positions and functions. The fixed pulleys 8 are symmetrically arranged at the top and sides of the suspension 2, respectively, and the movable pulleys 11 are symmetrically arranged at the top of the hanger 4, so that the bobbin 5 is driven by the second motor 10 to retract and release the rope, and the rope moves on the surfaces of the fixed pulleys 8 and the movable pulleys 11, and then a pulley block is formed with the help of the fixed pulleys 8 and the movable pulleys 11, thereby pulling the hanger 4 to perform vertical lifting operations, and the hanger 4 can drive the transformer to perform synchronous lifting operations.

[0019] In order to facilitate the lifting operation of the transformer, hooks 13 for lifting and connecting operations are evenly arranged around the lower part of the hanger 4. In order to prevent the transformer from shaking during the lifting process and easily detaching from the hooks 13, baffles 12 for shielding and limiting are also evenly arranged around the lower part of the hanger 4.

[0020] When in use, the gear box 9 is driven by the second motor 10 to operate, and then the gear box 9 is used to drive the wire drum 5 to perform the wire rope reel-in and release operation. Then the wire rope can drive the fixed pulley 8 and the movable pulley 11 to rotate through the contact between the pulleys, and then the hanger 4 can be pulled to perform vertical lifting operations. The hanger 4 is connected to the transformer through the hook 13 arranged at the bottom. During the lifting process, the baffle 12 can also be used to prevent the transformer from falling off from the hook 13. At the same time, the first motor 6 can also be used to drive the roller to move, so that the suspension 2 can be positioned along the overhead crane or the aerial track. In this way, the lifting and transportation operation of the transformer can be realized.
