Description

Technical Field

[0001] The invention relates to the technical field of electric power repair tools, in particular to an insulating bracket used for assisting the operation of an insulating rod. Background Art

[0002] Commonly used insulating rods generally have the following specifications: 3 sections of 4 meters weigh 1.5 kg, 3 sections of 5 meters weigh 2 kg, 4 sections of 4 meters weigh 1.82 kg, and 4 sections of 6 meters weigh 2.54 kg. The weight of those above 5 meters is relatively large, especially when operating high-altitude equipment. Single-person operation is time-consuming and labor-intensive. When operating isolation knives and drop insurance, if not affected by wind and temperature, a skilled worker takes an average of about 25 minutes for one operation process. If affected by wind, low temperature, or high temperature, a skilled worker takes an average of more than 30 minutes for one operation process.

[0003] For insulating poles longer than 5 meters, the length from the operator's handholding position to the operating head of the insulating pole is about 4.2 meters. If not affected by wind, the swing amplitude of the insulating pole is about 10 centimeters. If affected by wind, the swing amplitude of the insulating pole is more than 16 centimeters. Since the diameter of the isolation knife and drop insurance operating ring is about 4 centimeters, in the absence of wind, it takes about 3 minutes for a skilled worker to successfully hang on the operating ring. If affected by wind and proficiency, and if the worker needs to rest after holding the pole high for more than 5 minutes, it will take about 10 minutes to hang on the operating ring.

[0004] In addition, when using insulating poles longer than 5 meters, in order to improve the accuracy of the operation, on-site staff often use foot clips to climb the poles to shorten the operating distance. However, in actual operation, due to the influence of natural aging on the isolation knife and drop insurance, there is a problem of improper force causing the insulating bottle to fall or be damaged, which makes the crossbar and pole tower energized, seriously endangering the safety of the operators. Summary of the Invention

[0005] The present invention provides an insulating bracket for assisting the operation of an insulating rod, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problems of low operating efficiency, high labor intensity and high safety risks in the operation of the existing insulating rod during the isolation knife and drop insurance operation.

[0006] The technical solution of the present invention is achieved through the following measures: an insulating bracket for assisting the operation of an insulating rod, comprising a support block, a telescopic rod, an adjusting rod and a base that can be detachably fixedly installed on the outside of a pole tower, a telescopic rod that can be extended and retracted is provided between the right side of the base and the left side of the support block, the right side of the support block has a supporting surface, the supporting surface is inclined from top to bottom and from inside to outside, a telescopic adjusting rod is hingedly installed on the left side of the support block corresponding to the position below the telescopic rod, and the left end of the adjusting rod can be detachably installed together with the outside of the pole tower.

The right part of the clamp bulges to the right to form a guide groove opening to the left. A wedge is provided in the guide groove. The left side of the wedge is an arc surface matching the pole tower, and the right side of the wedge is an inclined surface with the upper part tilted to the right relative to the lower part. The left end of the adjusting rod is hingedly installed with the upper end of the wedge.

[0010] The above-mentioned base may include a rope tightener, a left mounting ring and a right mounting ring.

DETAILED DESCRIPTION

[0021] The present invention is not limited to the following embodiments, and specific implementation methods can be determined based on the technical solutions of the present invention and actual conditions.

[0022] In the present invention, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 The layout is described in detail, such as the positional relationships of front, back, top, bottom, left, and right are based on the Figure 1 The layout direction is determined by the

[0023] The present invention will be further described below in conjunction with the embodiments and accompanying drawings: Example 1: As shown in the attached Figures 1 to 4 As shown, the insulating bracket for assisting the operation of the insulating rod includes a support block 2, a telescopic rod 3, an adjusting rod 4 and a base that can be detachably fixedly installed on the outside of the pole tower 1. A telescopic rod 3 that can be retracted is provided between the right side of the base and the left side of the support block 2. The right side of the support block 2 has a supporting surface 5, and the supporting surface 5 is inclined from top to bottom and from inside to outside. A telescopic adjusting rod 4 is hingedly installed on the left side of the support block 2 corresponding to the position below the telescopic rod 3. The left end of the adjusting rod 4 can be detachably installed together with the outside of the pole tower 1.

[0024] According to the requirements, the adjustment rod 4 and the telescopic rod 3 are both the existing well-known telescopic rods 3, such as a telescopic hollow cylindrical rod made of rolled plastic sheets. During use, by setting a support surface 5 that is inclined from top to bottom and from inside to outside, the lower part of the insulating rod 19 is installed on the support surface 5 during the operation of the isolation knife and the drop safety. The support surface 5 can support the insulating rod 19, reduce the labor intensity of the operator, and prevent the operator from climbing the pole to operate the isolation knife and the drop safety. The personal safety of the on-site operators is guaranteed, and the operator can reduce the effort and on-site operation time, improve the efficiency of the pulling operation of the isolation knife and the drop safety, and fundamentally solve the problem that the insulating rod 19 is laborious, time-consuming, has a low success rate, and has safety risks in the operation of the isolation knife and the drop safety.

[0025] The above-mentioned insulating bracket for assisting the operation of the insulating rod may be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above example, as shown in the attached Figure 1 、 2 As shown in Figure 3, the support surface 5 is an inclined surface inclined from top to bottom and from inside to outside. A rotating shaft 6 is rotatably installed on the support surface 5, and a support plate 7 parallel to the support surface 5 is fixedly installed on the outside of the rotating shaft 6. The lower and upper parts of the support surface 5 are provided with fan-shaped grooves 8 that are coaxial and symmetrical with the rotating shaft 6. A guide rod 9 is slidably installed in each groove 8, and the right end of each guide rod 9 is fixedly installed with the left side of the support plate 7.

[0026] According to requirements, the guide rods 9 in the two grooves 8 are centrally symmetrical about the rotating axis 6, and the central angle corresponding to the two grooves 8 is 20 degrees to 90 degrees, that is, the angle range of rotation of each guide rod 9 along the rotating axis 6 is 20 degrees to 90 degrees. In this embodiment, the central angle corresponding to the two grooves 8 is 90 degrees.

[0027] During use, by setting the rotating shaft 6, the insulating rod 19 is placed on the supporting surface 5 of the support plate 7, and the support plate 7 can be rotated. In this way, the rotation of the insulating rod 19 can be realized, so that the three isolation knives or drop insurance on the pole tower 1 can be operated. In this way, there is no need to rotate the base, which can improve the working efficiency. The setting of the guide rod 9 and the groove 8 can support the support plate 7, thereby ensuring the stability of the support plate 7 during the rotation process. At the same time, the fan-shaped groove 8 can also limit the rotation angle of the support plate 7. After the support plate 7 rotates along the rotating shaft 6, the operator can operate the three isolation knives or drop insurance on the pole tower 1 through the insulating rod 19.

[0028] Example 3: As an optimization of the above embodiment, as shown in the attached Figure 4 As shown, an arc-shaped supporting groove 10 opening outward is provided on the right side of the supporting plate 7.

[0029] As required, the cross-section of the support groove 10 matches the cross-section of the insulating rod 19. During use, the angle of the support surface 5 is adjusted by adjusting the length of the telescopic rod 3 and the adjustment rod 4, that is, the inclination angle of the support groove 10 is adjusted, thereby adjusting the inclination angle of the insulating rod 19. This allows the operation of isolation knives and drop safety devices at different heights on the tower 1. By providing the arc-shaped support groove 10, a limiting effect can be exerted on the insulating rod 19, preventing the insulating rod 19 from swinging left and right on the surface of the support plate 7. This can avoid the safety risk of the insulating rod 19 swinging when operating the isolation knife or drop safety device, and solve the problem of the drop safety device being unable to be opened and closed at low temperatures (below -10 degrees Celsius), high temperatures (above 35 degrees Celsius), and wind swings.

[0030] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 1 、 5 As shown in Figures 6 and 7, a clamp 11 is detachably fixedly installed on the outer side of the pole tower 1 at the position below the corresponding base. The right part of the clamp 11 protrudes to the right to form a guide groove 12 opening to the left. A wedge 13 is provided in the guide groove 12. The left side of the wedge 13 is an arc surface matching the pole tower 1, and the right side of the wedge 13 is an inclined surface with the upper part inclined to the right relative to the lower part. The left end of the adjusting rod 4 is hingedly installed with the upper end of the wedge 13.

[0031] According to requirements, the right side inner wall of the guide groove 12 can be an inclined surface with the upper part tilted to the right relative to the lower part. The angle between the right side inner wall of the guide groove 12 and the vertical plane is smaller than the angle between the right side of the wedge block 13 and the vertical plane. A rubber anti-slip pad is fixed on the inside of the clamp 11, which can not only play an insulating effect, but also increase the friction between the clamp 11 and the pole, thereby preventing the clamp 11 from sliding down when operating the isolation knife or drop safety.

[0032] During use, by setting the clamp 11, it is convenient to disassemble and assemble the left end of the adjusting rod 4 and the pole tower 1. The setting of the wedge 13, after the left end of the adjusting rod 4 acts on the upper side of the wedge 13, the wedge 13 moves downward, so that the inclined surface of the wedge 13 and the inner wall of the guide groove 12 are against each other, which can make the connection between the clamp 11 and the pole tower 1 more secure, and the insulating rod 19 is more stable when operating the isolation knife or the drop insurance.

[0033] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1 、 8As shown, the base includes a rope tightener 14, a left mounting ring 15 and a right mounting ring 16. The left mounting ring 15 and the right mounting ring 16 are in an arc shape with openings facing each other. The rear of the left mounting ring 15 and the rear of the right mounting ring 16 are hingedly mounted together. The left end of the telescopic rod 3 is fixedly mounted to the right side of the right mounting ring 16. The rope tightener 14 is fixedly mounted on the front of the right mounting ring 16. A hook 17 is provided at the front of the left mounting ring 15. A connecting rope 18 with an end fixedly connected to the rope tightener 14 is passed through the hook 17.

[0034] As required, the rope tightener 14 is a conventionally known device, with an L-shaped hook 17 and a steel wire rope as the connecting rope 18. Rubber anti-slip pads or insulating pads are fixed to the insides of the left and right mounting rings 15 and 16. During use, the installation of the left and right mounting rings 15 and 16, along with the rope tightener 14, facilitates quick installation of the left and right mounting rings 15 and 16 outside the pole tower 1. The rope tightener 14 also allows for further tightening if the connecting rope 18 becomes loose, ensuring that each time the isolation blade or fall protection is operated, the left and right mounting rings 15 and 16 remain stably fixed to the pole tower 1.

[0035] The above technical features respectively constitute the embodiments of the present invention, which have strong adaptability and optimal implementation effects. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
