Description

Technical Field

[0001] The present invention relates to the technical field of oil-immersed transformers, and particularly relates to an oil-immersed transformer with self-traction hoisting type. Background Art

[0002] An oil-immersed transformer is a power transformer that uses transformer oil as an insulating and cooling medium; the oil-immersed transformer includes an iron core, windings, an oil tank, and insulating bushings: the oil-immersed transformer utilizes the principle of electromagnetic induction. When the primary winding is connected to an AC power supply, an alternating magnetic flux is generated in the iron core. This magnetic flux passes through both the primary winding and the secondary winding simultaneously. According to the law of electromagnetic induction, induced electromotive forces are respectively generated in the primary and secondary windings, thereby achieving voltage transformation.

[0003] Oil-immersed transformers are mostly installed on the top of utility poles. During the initial installation stage, first, manual workers install a reserved bracket at high altitude, and then install a hoisting device at the top of the utility pole. The manual workers rotate the hoisting device to tow the transformer or the hoisting device actively works to tow the transformer. The entire installation process requires a high degree of manual participation, and the operations are all completed at high altitude. The working space is small and the operation process is numerous, resulting in low construction efficiency and high construction risk of the oil-immersed transformer. Summary of the Invention

[0044] To solve the technical problems in the background art, the following self-traction hoisting type oil-immersed transformer is provided:

[0045] Combined with Figures 1 - 10 As shown, a self-traction hoisting type oil-immersed transformer provided by the present invention includes a main chassis 1 with a storage box 11 built therein;

[0046] The climbing component 3 is installed on the side of the main chassis 1. The climbing component 3 clamps the left and right sides of the electric pole 9b.

[0047] The lower clamping component 2 is installed on the bottom surface of the main chassis 1. The lower clamping component 2 is located at the bottom of the climbing component 3. The lower clamping component 2 clamps the front and rear sides of the electric pole 9b to prevent the main chassis 1 from tilting forward and backward, and the lower clamping component 2 is used to prevent the main chassis 1 from dropping excessively.

[0048] The reserved bracket 4 is clamped and installed on the outer wall of the electric pole 9b. The reserved bracket 4 is placed above the main chassis 1.

[0049] The suspension component 6 includes a first hanger 61, a second hanger 62, a wire wheel 63 and an end plate 64. Both the first hanger 61 and the second hanger 62 are in the shape of "7". Both the first hanger 61 and the second hanger 62 extend outward. An activity gap for avoiding the main body of the transformer 9a is left between the first hanger 61 and the second hanger 62. The bottom ends of the first hanger 61 and the second hanger 62 are fixedly arranged on the front and rear side surfaces of the main chassis 1. The outer extension ends of the first hanger 61 and the second hanger 62 are connected into one body through the end plate 64.

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

[0051] The outer clamping component 5 is installed on the top surface of the main chassis 1. The outer clamping component 5 is clamped and connected to the reserved bracket 4.

[0053] The outer blocking component 9 is rotatably installed at the outer end of the rotating component 8. The outer blocking component 9 cooperates and abuts against the side of the electric pole 9b to prevent the main body from tilting left and right.

[0054] In the above solution:

[0055] 1. The climbing component is designed to actively drive the lifting and lowering movement of the main chassis, and then drive the suspension component, the lifting component and the reserved bracket to move accordingly, realizing the automatic lifting and positioning of the main body of the transformer and the reserved bracket. Workers only need to set up at the bottom of the electric pole, and there is no need for manual high-altitude traction operation, which is safer, and the operation stability and efficiency are also higher.

[0056] 2. Design the lower clamping assembly, which can achieve auxiliary restraint in the front-back direction on the one hand, and on the other hand, in case of emergency fall, the lower clamping assembly can play the final locking effect to ensure the safety of the climbing assembly operation;

[0059] 5. After the reserved bracket is installed in place, the lifting assembly will carry out the lifting operation to avoid excessive force on the climbing assembly in the early stage. The lifting assembly first pulls the transformer body up. Subsequently, the lifting assembly moves along the suspension assembly to insert the transformer body onto the reserved bracket, realizing the docking of the transformer body and the reserved bracket;

[0060] An activity gap is left between the first hanger and the second hanger, so that when the climbing assembly descends, the transformer body can pass through the activity gap relatively, enabling the climbing assembly and the lifting assembly to descend and be recycled normally;

[0061] 6. Design a rotatable outer blocking assembly, which rotates and retracts outward during use to not affect the installation of other components.

When the lifting is in place, the insertion post is inserted into the hanging pipe, and the constraint cover can facilitate the smooth insertion of the insertion post into the hanging pipe.

[0079] When the transformer is installed at a high altitude, wiring operations need to be carried out. At present, the cable layout of the transformer is cumbersome, the cable size is large and the weight is large, and manual hoisting is also required. To achieve the rapid hoisting of the cable, the following solution is given:

[0080] In this embodiment, a linear array of wire head clamping components 73 is arranged on the bottom surface of the loading plate 71. The wire head clamping components 73 are used to clamp the head of the cable and pull and lift the cable, so that workers can carry out the high-altitude wiring of the cable and the transformer; the wire head clamping components 73 and the guide pulley 63 are distributed oppositely;

[0081] The wire-end clamping component 73 includes a lower cylinder body 732, an upper cylinder body 731, and a side positioning plate 733. The upper cylinder body 731 is arranged on the bottom surface of the loading plate 71. One side of the bottom surface of the upper cylinder body 731 is connected to the lower cylinder body 732 through the side positioning plate 733. The lower cylinder body 732 is relatively arranged directly below the upper cylinder body 731. An adjusting screw rod 736 is threadedly penetrated through the middle part inside the lower cylinder body 732. The top end of the adjusting screw rod 736 is rotatably connected to a lower clamping plate 734.

One side of the bottom surface of the lower clamping plate 734 is vertically provided with a guide rod 737, and the guide rod 737 is slidably embedded in the lower cylinder body 732.

[0082] In the above solution: a wire-end clamping component is added at the bottom of the loading plate. The cable first passes through the wire guide wheel, and then the end of the cable is extended into the wire-end clamping component. The adjusting screw rod is rotated to make the lower clamping plate move upward to clamp the wire end of the cable. The cable is fixed between the lower clamping plate and the upper cylinder body, and the guide rod guides the movement of the lower clamping plate. As the lifting component is lifted, the cable will also be driven to be lifted, realizing the high-altitude presetting of the cable. When the transformer body is installed on the reserved bracket, the preset cable is convenient for the workers to connect the wires.

[0083] In this embodiment, the bottom surface of the upper cylinder body 731 is provided with anti-slip lines 7331, and a storage groove 7332 is opened on the outer side of the bottom surface of the upper cylinder body 731. The outer side of the top surface of the lower cylinder body 732 is vertically provided with a side baffle 735, and the side baffle 735 is inserted into the storage groove 7332 in a matching manner. The side baffle 735 is used to stop and restrain the cable from the outside.

[0084] In the above solution: the setting of the anti-slip lines can improve the clamping firmness and prevent the cable from detaching. The side baffle can stop and restrain the cable from the outside to prevent the end of the cable from shifting left and right.
