Description
The technical field is as follows:
the utility model relates to an electric power industry circuit maintenance equipment technical field especially relates to a nut binding of transmission line yoke plate.
Background art:
in the daily operation of the strain tower of the overhead transmission line. Because the triangular yoke plate, the adjusting plate, the right-angle hanging plate, the parallel hanging plate and the like are exposed all the year round, under the action of wind power, the bolt and the yoke plate generate relative motion, and if the time is long, the yoke plate bolt and the yoke plate nut are loosened. And finally, the insulator string or the lead falls down when the accident is serious. Therefore, one of the work contents of the regular maintenance of the tension tower of the high-voltage overhead transmission line is the fastening of the triangular yoke plate, the adjusting plate and the right-angle hanging plate by bolts and nuts. However, with the development of economy, the society has more and more large demand for electric power, the reduction of power failure time and the improvement of customer satisfaction are the main attack directions of current power grid enterprises, and the power failure maintenance can bring huge economic loss. Therefore, the defects are processed by live working, live maintenance avoids equipment power failure, and the safety, stability and economy of the power system are improved. The existing methods for processing the defects in the live-line maintenance need to perform electric field operation in an equipotential mode, namely a suspended rope ladder equipotential electric field entering method or an insulated flat ladder equipotential electric field entering method. The two methods all need more electrified tools and can be completed by at least 5 persons, the operation method is complex, the technical requirements on operators are high, the danger coefficient is large, time and labor are wasted, the labor intensity is high, and the working efficiency is low.
The utility model has the following contents:
an object of the utility model is to provide a fastening transmission line yoke plate nut's specialized tool, this instrument are used for fastening the nut that becomes flexible on the transmission line yoke plate, perhaps mend the dress to the nut that drops and fasten. The overall quality and the replacement speed of the power transmission line yoke plate are improved, and the safety of personnel and the safe and stable operation of the power transmission line are ensured.
The utility model provides a technical scheme that its technical problem adopted is: a nut fastener of a power transmission line yoke plate comprises a connecting rod, a jaw type connecting device, a ratchet wrench, a sliding block, a hanging hook and a spring, wherein the jaw type connecting device is fixedly arranged at one end of the connecting rod, the other end of the connecting rod is hinged with the tail end of a handle of the ratchet wrench, a sliding groove is formed in the side wall of the middle of the connecting rod, and the sliding block is arranged in the sliding groove in a sliding mode; the handle of the ratchet wrench is provided with the hanging hook which is vertically arranged with the handle of the ratchet wrench; and two ends of the spring are respectively connected with the sliding block and the middle part of the handle of the ratchet wrench.
The utility model has the advantages that: the structure is simple and reasonable, the operation is convenient and reliable, the end part of the horizontal connecting rod is provided with the tooth clamp type connecting device which can be connected with the insulating rod, the carrying and the storage are convenient, and the quick assembly and disassembly of the nut fastener are realized; the staff stands the operation that can carry out the repacking on the shaft tower, need not to climb up to treating corresponding department and construct, has reduced maintainer's intensity of labour and the construction degree of difficulty, the effectual work efficiency and the construction security that have improved.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an explanatory view of the present invention.
The connecting rod 1, the jaw type connecting device 2, the ratchet wrench 3, the sliding block 4, the suspension hook 5, the spring 6, the sliding groove 7, the insulating rod 8, the triangular connecting plate 9 and the nut 10.
The specific implementation mode is as follows:
example 1: as shown in fig. 1, the nut fastener of the power transmission line yoke plate comprises a connecting rod 1, a jaw type connecting device 2, a ratchet wrench 3, a sliding block 4, a suspension hook 5 and a spring 6, wherein the jaw type connecting device 2 is fixedly arranged at one end of the connecting rod 1, the other end of the connecting rod 1 is hinged with the tail end of a handle of the ratchet wrench 3, a sliding groove 7 is arranged on the side wall of the middle part of the connecting rod 1, and the sliding block 4 is arranged in the sliding groove 7 in a sliding manner; the handle of the ratchet wrench 3 is provided with the hanging hook 5 which is vertically arranged with the handle of the ratchet wrench 3; and two ends of the spring 6 are respectively connected with the slider 4 and the middle part of the handle of the ratchet wrench 3.
Instructions for use: as shown in fig. 2, is connected with the insulating rod 8 through a jaw connection part; a worker stands on a tower, operates the insulating rod 8, and sleeves the ratchet wrench 3 on the nut 10 of the triangular yoke plate 9; the hanging hook 5 can be hung on a structural part near the nut 10, so that the ratchet wrench 3 can be conveniently sleeved on the nut 10; the insulating rod 8 is pulled to and fro, and the nut 10 is screwed through the ratchet wrench 3; in the process of pulling the insulating rod 8 again, the sliding block 4 slides and displaces in the sliding chute 7, and a reciprocating connecting rod structure is formed between the connecting rod 1 and the handle of the ratchet wrench 3 under the action of the elastic force of the spring 6; after the nut 10 is tightened, the insulating rod 8 is operated to remove the ratchet wrench 3 from the nut 10 of the triangular yoke plate 9, thereby completing the fastening operation of the nut 10.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
