Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a lead adjustment device for high-voltage testing of electrical equipment. Background Technology

[0002] During high-voltage testing of electrical equipment, high-voltage power lines need to be erected. The high-voltage power lines are fixed to the high-voltage power tower by insulated wires. In this process, the insulated wires are usually pulled by the high-voltage test lead to raise them and move them to the position of the lifting ring. The pulling device of the high-voltage test lead is usually set on the ground. Therefore, pulleys need to be temporarily installed on the high-voltage power tower. The pulling direction of the high-voltage test lead is changed by the pulleys. Therefore, a lead adjustment device is required.

[0003] Chinese patent document CN118884003B discloses a lead wire adjustment device for high-voltage testing of electrical equipment, including an insulated wire and a lifting ring. The device includes a lead wire adjustment assembly comprising a movable bracket, a first U-shaped wheel, a second U-shaped wheel, a high-voltage test lead wire, a strip groove, and a hook assembly. One end of the movable bracket is rotatably connected to the first U-shaped wheel. The lead wire adjustment assembly can be installed close to the lifting ring. When the high-voltage test lead wire pulls the insulated wire upwards to a position near the lifting ring via the steering of the lead wire adjustment assembly, the position of the high-voltage test lead wire can be further changed by altering the angle of the lead wire adjustment assembly itself, thereby further changing the position of the insulated wire. This allows for fine-tuning of the insulated wire position, enabling it to contact the lifting ring and thus facilitating its fixed installation.

[0004] The existing technology has the following problems:

[0005] When using the lead adjustment device for high-voltage testing of electrical equipment, it cannot provide adequate protection for the upward-moving insulation wire, thus affecting the stability during the upward movement. Furthermore, the lead adjustment device for high-voltage testing of electrical equipment does not facilitate the quick fixing and removal of the insulation wire. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1As shown, a lead adjustment device for high-voltage testing of electrical equipment includes a connecting crossbar 1. Protective components 2 are fixedly connected to both the left and right sides of the connecting crossbar 1. High-voltage test leads 3 are movably sleeved on the inner walls of the two protective components 2. Fixed components 4 are fixedly connected to the lower surfaces of the front parts of the two high-voltage test leads 3. Fixed rings 5 ​​are snapped into the inner walls of the middle part of the fixed components 4. Insulating wires 6 are fixedly connected to the lower surface of the fixed rings 5 ​​and the insulating wires 6 are located below the fixed components 4.

[0027] First, snap the fixing ring 5 onto the inner wall of the middle part of the fixing component 4, so that the insulating wire 6 is fixed below the fixing component 4. Then, pull the two high-voltage test leads 3, so that the fixing component 4 moves upward under the action of the two protective components 2, thereby allowing the fixing ring 5 and the insulating wire 6 to move to the position of the lifting ring. Then, fix the moved fixing ring 5 and the insulating wire 6 below the lifting ring.

[0028] like Figure 2 , Figure 3 As shown, the fixing component 4 includes a support plate 41. The left and right parts of the upper surface of the support plate 41 are fixedly connected to the lower surfaces of the two high-voltage test leads 3 respectively. Two symmetrical limiting blocks 42 are fixedly connected to the upper surface of the middle part of the support plate 41. U-shaped limiting grooves are opened on the opposite surfaces of the two limiting blocks 42. A limiting groove 45 is opened on the front of the middle part of the support plate 41.

[0029] The two limiting blocks 42 ensure that the fixing ring 5 is confined inside the limiting groove 45 when it is placed on the market, thereby ensuring the stability of the upward movement process. At the same time, it is easy to remove after fixing, so that the fixing ring 5 and the insulating wire 6 can be quickly fixed and removed during use.

[0030] An elastic rubber pad 43 is fixedly connected inside the U-shaped limiting groove of the limiting block 42, and a wear-resistant pad 44 is fixedly connected to the inner wall of the elastic rubber pad 43.

[0031] The elastic rubber pad 43 and the wear-resistant pad 44 provide a certain degree of buffer protection when the fixed ring 5 is confined between the two limit blocks 42, thereby ensuring safety during movement.

[0032] like Figure 4As shown, the two protective components 2 include two U-shaped shells 22. The opposite faces of the two U-shaped shells 22 are fixedly connected to the left and right sides of the connecting crossbar 1, respectively. Hooks 21 are fixedly connected to the upper surfaces of the two U-shaped shells 22. The inner walls of the upper part of the two U-shaped shells 22 are rotatably connected to pulleys 23. The upper surfaces of the outer walls of the middle part of the two pulleys 23 overlap with the outer walls of the upper part of the two high-voltage test leads 3. Fixing rods 24 are fixedly connected to the left and right sides of the U-shaped shells 22. Limiting ring plates 25 are movably sleeved on the outer walls of the opposite parts of the two fixing rods 24. The two limiting ring plates 25 are located on the left and right sides of the U-shaped shells 22, respectively. Support blocks 26 are movably sleeved on the inner walls of the lower part of the two limiting ring plates 25. The two support blocks 26 are located in front of the U-shaped shells 22. The opposite faces of the two support blocks 26 are rotatably connected to pulleys 27. The pulleys 27 are located in front of and below pulleys 23. The outer wall of the middle part of pulleys 27 overlaps with the outer wall of the high-voltage test leads 3.

[0033] The two pulleys 23 enable the two high-voltage test leads 3 to move the support plate 41 upwards. With the assistance of the two pulleys 27, the high-voltage test leads 3 can move the support plate 41 in front of the two U-shaped shells 22, which facilitates the movement of the insulating wire 6 to the front of the lifting ring for easy fixing. The two pulleys 27 can move back and forth while maintaining stability under the action of the fixing rod 24 and the limiting ring plate 25.

[0034] like Figure 5 As shown, each of the two support blocks 26 is fixedly connected to a sleeve rod 28, and the two sleeve rods 28 are located below the fixed rod 24 and the pulley 23. The rear part of the outer wall of each of the two sleeve rods 28 is slidably connected to a sleeve rod 29, and the rear of the two sleeve rods 29 is fixedly connected to the front of the lower part of the U-shaped shell 22 respectively.

[0035] Through the action of sleeve rod 28 and sleeve rod 29, the two support blocks 26 can move back and forth, thereby enabling pulley 27 to move back and forth stably and play a guiding role.

[0036] A spring 210 is fixedly connected to the inner wall of sleeve 28, and the rear of spring 210 is fixedly connected to the inner wall of sleeve 29.

[0037] The spring 210 provides a buffer space between sleeve rod 28 and sleeve rod 29, thus enabling pulley 27 to provide a certain buffering protection when supporting the movement of the auxiliary high voltage test lead 3.

[0038] The working principle of this utility model is as follows: First, the fixing ring 5 is snapped into the inside of the limiting groove 45 and the limiting block 42. The elastic rubber pad 43 and the wear-resistant pad 44 provide a certain buffer protection when the fixing ring 5 is restricted between the two limiting blocks 42. Then, the two high-voltage test leads 3 are pulled, so that the support plate 41 moves upward under the action of the two pulleys 23. At this time, the pulley 27 and the spring 210 provide a certain buffer protection when the high-voltage test leads 3 move upward, so that the fixing ring 5 and the insulating wire 6 can move to the position of the lifting ring. Then, the upward-moving fixing ring 5 and the insulating wire 6 are fixed below the lifting ring.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
