Abstract

The invention relates to a universal fixture which is suitable for the operation of replacing a poor insulator in the case of power failure in the power transmission profession. The universal fixture comprises two fasteners; the fasteners are connected by a screw rod; the screw rod is provided with a ratchet wrench; and each fastener is of a structure that upper and lower clamping grooves are oppositely arranged and the upper and lower clamping grooves are connected by a bolt. According to the invention, by regulating the bolts of the clamping grooves, the sizes of the clamping grooves are replaced and various types of insulators of the same tension load iron hat, which have different sizes, are fixed to achieve the effects of transferring a load and regulating an overhung gap so as to replace the insulators; the universal fixture has safe and reliable performance, is flexible and light and is convenient and labor-saving to use; labor intensity of operators is reduced; and operation efficiency is improved.

Description

Universal fixture

technical field

The present invention relates to a clamp, in particular to a general-purpose clamp, which is suitable for the operation of replacing bad insulators in power transmission professional power outages.

technical background

Existing fixtures can only be used for insulators of the corresponding model and the same size of iron cap, but now the insulators with the same tensile load on the transmission line have different iron cap sizes, even on the same line, the insulators used The iron caps are also different. In the daily work of replacing insulators, it always happens that the specifications of the clamps do not match the insulators, so they cannot be used. Therefore, when changing, they carry multiple types of clamps, which not only increases the workload, but also is very troublesome to operate.

Contents of the invention

The present invention aims at the above-mentioned shortcomings in the prior art, and provides a universal clamp, which solves the problem that the clamp in the prior art cannot be used universally.

Technical scheme of the present invention is as follows:

The fixture includes two fasteners, the solid pieces are connected by a screw, and a ratchet wrench is provided on the screw; the structure of the fastener is that the upper and lower clamping grooves are arranged oppositely, and the upper and lower clamping grooves connected by bolts.

Described leading screw is made of forward threaded threaded screw and reverse threaded threaded screw.

The card slot is semicircular concave.

Both sides of the card slot are respectively provided with a long threaded opening and a circular threaded opening.

The elongated threaded opening and the circular threaded opening are respectively matched with bolts.

Compared with the prior art, the present invention has the following effects:

1. Change the size of the slot by adjusting the slot bolt, and fix various types of insulators with the same tensile load and different sizes of iron caps, so as to transfer the load and adjust the suspension gap to replace the insulator.

2. Easy to operate. The general-purpose fixture is a modified version of the ordinary fixture. The method of using it is basically the same as that of the ordinary fixture. The transmission workers can use it skillfully without training.

3. The performance is safe and reliable, using high-strength aluminum alloy material, flexible and light, easy to use and labor-saving, reducing the labor intensity of operators and improving work efficiency.

4. The mechanical strength of the fixture is improved to ensure that the fixture will not break during use, nor will it break other insulators due to the loosening of the clamping slot.

5. It is very easy to replace insulators with the same tensile load and different sizes of iron caps, which greatly improves the work efficiency of replacing bad insulators during power outages, reduces the labor intensity of operators, and reduces operating costs.

Description of drawings

Fig. 1 is a schematic diagram of the structure of the present invention.

Fig. 2 is a structural schematic diagram of the fastener of the present invention.

In the figure, 1. fasteners, 2. forward threaded screw, 3. reverse threaded screw, 4. ratchet wrench, 5. card slot, 6. bolt.

Detailed ways

Referring to the accompanying drawings and in conjunction with specific embodiments, the present invention is described in detail as follows.

Example

As shown in Figure 1-2, the fixture includes two fasteners 1, and the fasteners 1 are connected by a screw. The screw is composed of a forward screw 2 and a reverse screw 3. Ratchet wrench 4; the structure of the fastener is that the upper and lower semicircular concave draw-in slots 5 are arranged oppositely, and the two sides of the upper and lower draw-in slots are respectively provided with elongated threaded openings and circular threaded openings, and the elongated threaded openings and the bolts 6 are matched to form the adjustment end, and the circular threaded port is matched with the bolt to form the fixed end.

The usage method of the present invention is as follows: 1) When fixing, open the slot at the opening, fix the slot to the iron cap, adjust the size of the slot by adjusting the bolt, and then tighten the bolt firmly to hold the iron cap stably. To achieve the purpose of transferring load. 2) Adjust the ratchet wrench, adjust the hanging gap, remove the damaged insulator if it is loose, and install a good insulator. Continue to adjust the ratchet wrench, adjust the suspension gap, and make the fixture out of the stressed state. 3) Adjust the slotted bolts and remove the clamps.

The above are specific embodiments of the present invention and the applied technical principles. Any equivalent transformation based on the technical solution of the present invention falls within the scope of protection of the present invention.
