Description

Technical Field

[0001] The present invention relates to the technical field of oil-immersed transformers, in particular to a self-traction hoisting type oil-immersed transformer. Background Art

[0002] An oil-immersed transformer is a power transformer that uses transformer oil as its insulation and cooling medium. It consists of an iron core, windings, an oil tank, and insulating bushings. Oil-immersed transformers utilize the principle of electromagnetic induction. When the primary winding is connected to an AC power source, an alternating magnetic flux is generated in the iron core. This flux passes through both the primary and secondary windings, generating induced electromotive forces in each winding according to the law of electromagnetic induction, thereby achieving voltage conversion.

[0003] Oil-immersed transformers are mostly installed on the top of electric poles. In the early installation stage, the reserved bracket is first installed manually at high altitude, and then the lifting equipment is installed on the top of the electric pole. The lifting equipment is manually rotated to pull the transformer or the lifting equipment actively works to pull the transformer. The entire installation process requires a high degree of manual participation, and all operations are completed at high altitude. The working space is small and there are many work processes, resulting in low construction efficiency and high construction risks of oil-immersed transformers. Summary of the Invention

[0029] 3. The lifting assembly will only start the lifting operation after the reserved bracket is installed in place to avoid excessive force on the climbing assembly in the early stage; the lifting assembly first pulls the transformer body up, and then the lifting assembly moves horizontally along the suspension assembly to insert the transformer body into the reserved bracket, realizing the docking of the transformer body and the reserved bracket; a movable gap is left between the first hanger and the second hanger so that when the climbing assembly descends, the transformer body can relatively pass through the movable gap, so that the climbing assembly and the lifting assembly can be normally lowered and recovered;

[0030] 4. Design a rotatable outer block component, which is rotated outward and retracted when in use so as not to affect the installation of other components. When all components are installed, the outer block component is rotated inward and can stop from one side to prevent the climbing component and the main chassis from shifting left and right, thereby ensuring the stability of the main chassis.

[0047] The lower clamping assembly 2 is mounted on the bottom surface of the main box 1. The lower clamping assembly 2 is located at the bottom of the climbing assembly 3. The lower clamping assembly 2 is clamped on the front and rear sides of the pole 9b to prevent the main box 1 from tilting forward and backward. The lower clamping assembly 2 is used to prevent the main box 1 from falling excessively.

[0049] The suspension assembly 6 includes a first hanger 61, a second hanger 62, a wire pulley 63, and an end plate 64. The first hanger 61 and the second hanger 62 are both in the shape of a "7".

The bottom ends of the first hanger 61 and the second hanger 62 are fixed to the front and rear sides of the main chassis 1. The outwardly extending ends of the first hanger 61 and the second hanger 62 are connected as a whole by the end plate 64. The bottom surface of the end plate 64 is installed with a linear array of wire pulleys 63. The wire pulleys 63 are used to guide the cables to be connected to the transformer body 9a.

[0050] A lifting assembly 7 is horizontally slidably installed between the first hanger 61 and the second hanger 62. The lifting assembly 7 is used to vertically lift the transformer body 9a and horizontally transfer it to the reserved bracket 4;

[0054] In the above scheme:

[0055] 1. The climbing component design can actively drive the main box to move up and down, and then drive the suspension component, lifting component, and reserved bracket to follow the movement, so as to realize the automatic lifting of the transformer body and the reserved bracket into place. Manual work only needs to be set up at the bottom of the pole, and no manual high-altitude traction operation is required, which is safer, more stable and more efficient;

After the reserved bracket is installed in place, the lifting assembly will start the lifting operation to avoid excessive force on the climbing assembly in the early stage; the lifting assembly will first pull the transformer body up, and then the lifting assembly will move horizontally along the suspension assembly to insert the transformer body into the reserved bracket, so as to achieve the docking of the transformer body and the reserved bracket;

[0060] A movable gap is left between the first hanger and the second hanger so that when the climbing assembly descends, the transformer body can relatively pass through the movable gap, so that the climbing assembly and the lifting assembly can be normally lowered and recovered;

[0061] 6. Design a rotatable outer block component, which is rotated outward and retracted when in use so as not to affect the installation of other components.

[0071] Then, the worker adjusts the climbing assembly to be mounted on the pole, and the clamping sleeve is clamped on the first side frame and the second side frame; then the worker adjusts the clamping position of the lower clamping assembly and the outer block assembly;

[0072] When the climbing assembly drives the reserved bracket to be lifted into place, the hexagonal plate drives the hexagonal cap to rotate, so that the locking screw is screwed into the connecting sleeve, and the two sets of clamps are clamped and fixed on the pole.
