Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0027] This invention provides an adjustable-width glass insulator replacement holder, comprising two parallel insulating rods 1, and further comprising:
[0028] The width adjustment module 2 is set between the two insulating rods 1 and fixedly connected to each insulating rod 1, and is used to adjust the relative distance between the two insulating rods 1.
[0029] Limiting module 3 is set at one end of the two insulating rods 1 to limit the movement of the tension string insulator along the direction of the bottle support frame;
[0030] The lifting module 4 is located at the end of the two insulating rods 1 away from the limit module 3, and is used to lift the equipment to a high place for work after it has been adjusted on the ground.
[0031] This invention is a technical modification of the original fixed bottle support frame. By adjusting the width module 2, the original fixed bottle support frame is replaced with a caliper-type adjustable frame. The width adjustment module 2 is equipped with a locking device. In actual operation, the pole operator only needs to measure the diameter of the insulator porcelain skirt and inform the ground operator. The ground operator then adjusts the width of the bottle support frame on the ground, and the bottle support frame can be lifted to the pole position by the lifting device to carry out the insulator replacement work. During the insulator replacement work, the limit module 3, in conjunction with the lifting module 4, restricts the movement of the tension string insulator along the bottle support frame direction.
[0032] As a specific embodiment of the present invention, the width adjustment module 2 includes two sets of double-ended screws 201 and width adjustment nuts 202 that match the double-ended screws 201. The two sets of double-ended screws 201 are installed parallel to each other symmetrically about the middle of the two insulating rods 1 and pass through the two insulating rods 1. The threads at both ends of each double-ended screw 201 have opposite directions. Each insulating rod 1 has a threaded hole at the position where the double-ended screw 201 passes through, which has the same thread direction as the thread of the double-ended screw 201 passing through that position. Multiple width adjustment nuts 202 are installed on each double-ended screw 201 located outside the insulating rod 1.
[0033] During operation, the personnel working on the pole measure the diameter of the insulator porcelain skirt and inform the ground coordinator. The ground coordinator then adjusts the width of the bottle holder on the ground. When the width of the bottle holder needs to be adjusted, first loosen the width adjusting nut 202, and then rotate the double-ended screw 201 in both forward and reverse directions to widen or narrow the center distance between the two insulator rods 1, thereby making the width of the bottle holder adjustable. After adjustment, tighten the width adjusting nut 202 to lock it.
[0034] The limiting module 3 includes a bottle holder limiting hanger 301. The bottle holder limiting hanger 301 has a structure in which two arc rods are symmetrically fixedly installed below a straight rod. An installation screw 302 is fixedly connected to the upper part of the middle of the straight rod. The two insulating rods 1 can pass through the two arc rods respectively. The installation screw 302 is connected to the installation component located at the insulator.
[0035] When replacing glass insulators, a large-blade clamp is usually used with a bottle support frame to replace the tension string insulator. During replacement, the tension string insulator will move along the bottle support frame. Therefore, a bottle support limiting device is set up. The mounting screw 302 is fixedly connected to the large-blade clamp to fix the limiting module 3. Then, the insulating rod 1 passes through the two arc rods. The tension string insulator located above the insulating rod 1 will be restricted by the limiting device to move along the bottle support frame, so as to reduce the difficulty of replacing glass insulators.
[0036] The lifting module 4 includes a lifting rod 401 and a connecting part 402. The lifting rod 401 is triangular in shape, and its two corners are rotatably connected to two insulating rods 1 via the connecting part 402. The connecting part 402 includes a fixing plug 4021, an adjusting screw 4022, and an adjusting nut 4023. The fixing plug 4021 is fixedly connected to the port of each insulating rod 1 near the lifting module 4. Each fixing plug 4021 has a through hole through which the adjusting screw 4022 can pass. One side of the lifting rod 401 connecting to the two connecting parts 402 is a hollow shaft. The adjusting screw 4022 passes through the through hole in one fixing plug 4021, then through the hollow shaft of the lifting rod 401, and finally through the through hole in the other fixing plug 4021. Four adjusting nuts 4023 are provided, distributed on both sides of the through hole of each fixing plug 4021, for clamping the fixing plug 4021 and the lifting rod 401.
[0037] The pole-mounted workers measure the diameter of the insulator's porcelain skirt and inform the ground-based coordinators. The ground-based coordinators then adjust the width of the bottle support frame on the ground. When adjusting the center distance of the insulating rod 1, all adjusting nuts 4023 are loosened, allowing the fixed plug 4021 to move along the adjusting screw 4022. After the center distance of the insulating rod 1 is adjusted, the adjusting nuts 4023 are tightened. The device is then hoisted from the ground to the pole-mounted workers using existing lifting equipment such as a crane or ropes, and fixed to the large knife clamp. By loosening the adjusting nuts 4023, the angle between the lifting rod 401 and the insulating rod 1 can be adjusted to form a right angle, which, together with the limiting module 3, restricts the movement of the insulator along the bottle support frame, reducing the difficulty of replacing glass insulators.
[0038] An insulating rod 1 is equipped with a tension insulator fixing rope 5. Both ends of the tension insulator fixing rope 5 are fixedly connected to two insulating rods 1 respectively. The length of the tension insulator fixing rope 5 is much greater than the maximum width of the two insulating rods 1. One end of the tension insulator fixing rope 5 is equipped with a tightening device for tightening the tension insulator fixing rope 5. The tightening device includes a rope puller 6, from which a tension rope 7 extends and is fixedly connected to one end of the tension insulator fixing rope 5.
[0039] One end of the tension string insulator fixing rope 5 is connected to an insulating rod 1, and the other end can pass through the insulating rod 1 and connect to the tension rope 7. During installation, after the tension string insulator is passed under the tension string insulator fixing rope 5, the rope puller 6 is pulled, and the tension string insulator fixing rope 5 will be tightened to fix the tension string insulator, thereby preventing the tension string insulator from rolling or tipping over on the bottle support, thus reducing the difficulty of replacing glass insulators.
[0040] Multiple fixing ropes 5 can be set for tension string insulators to fix longer tension string insulators at multiple points.
[0041] This invention is a technical modification of the original fixed bottle support frame. The original fixed bottle support frame width is replaced with a caliper-type adjustable frame equipped with a locking device. In actual operation, the pole operator only needs to measure the diameter of the insulator porcelain skirt and inform the ground coordinator. The ground coordinator then adjusts the width of the bottle support frame on the ground, and the bottle support frame can be lifted to the pole position to carry out the insulator replacement work.
[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
