Abstract
The utility model discloses a force-bearing combination tool for replacing a double-string insulator. The force-bearing combination tool comprises an insulator cradle, a pulling plate, an open wrench (1) and a back fixture (10), wherein the open wrench (1) consists of two open wrench sheets which are the same as each other and is provided with a bolt (3) and a bolt screw hole (2). The force-bearing combination tool is characterized in that: a screw rod (5) with a nut handle (6) is arranged between the tail ends of upper and lower open wrench sheets; a screw rod port (4) is movably connected with the pulling plate; the other end of the pulling plate is tied at one end of the back fixture (10); the two back fixtures are arranged on a wire end hardware fitting; one opening of the open wrench (1) hooks a cross arm of the insulator which is arranged on a mid-point bolt; and the force-bearing combination tool is only operated by two persons, the insulator is combined, connected and replaced by one person using an on-line wire end and the other person using a rod tower end. The force-bearing combination tool has the positive effects that: the fixture has simple structure, light weight, simple and convenient maintenance process and high efficiency, is convenient to carry, is easy to install, is safe and reliable, saves time, decreases the number of operating personnel and greatly lowers labor intensity.
Description
Technical field the utility model relates to a kind of power circuit service kit, particularly a kind of 220KV strain insulator porcelain vase hotline maintenance special mould clamp.
Background technology adopts instruments such as bottle supporting frame, hoist to pull cooperation by the person of reaching the standard grade and the many people of ground staff in prior art and finishes the replacing insulator, and its labour intensity is big, personnel selection is many and the personal security sense is not good enough, time-consuming, inefficiency.
The summary of the invention the purpose of this utility model is to provide the novel replacing of a cover two insulator string load instruments, can solve the two string of charged for replacement duplex zero resistance insulator problem.
The technical scheme that its technical problem that solves the utility model adopts: this cover load instrument comprises bottle supporting frame, arm-tie, open-end wrench and back jig, encapsulation of open-end wrench has the screw mandrel of band crank handle, screw mandrel termination bolt is placed on the arm-tie, the arm-tie other end is bolted on the jig of back, back jig pincers are set on the lead side tetrad plate, and the middle part is provided with screw, nut on the back jig, and two ends are provided with trim ring, the open spanner hand vice are set in the cross-arm side, and the bottle supporting frame is tethered on the cross-arm of insulator two ends.
The beneficial effects of the utility model are: main innovation of the present utility model partly is the jig of band screw mandrel spanner, it has substituted the hoist that the many people of a pair of needs pull, labour intensity is big, unsafe, and jig is simple in structure, in light weight, be easy to carry, maintenance process is easy and simple to handle, easy installation, time-saving and efficiency, minimizing operating personnel quantity, reduce labour intensity, safe and reliable greatly.
In the description of drawings 1 for open-end wrench, 2 for the bolt screw, 3 for bolt, 4 for shaking the hand, 7 be nut for screw, 13 for trim ring, 12 for back jig, 11 for flat key, 10 for axle sleeve, 9 for support, 8 for the feed screw nut for screw mandrel, 6 in screw mandrel termination, 5.
Embodiment is referring to accompanying drawing 1,2 the utility model comprise the bottle supporting frame, arm-tie, open-end wrench 1 and back jig 10, open-end wrench 1 is two the same open-end wrench sheets, which is provided with bolt 3, bolt screw 2, be provided with up and down shake the hand 6 screw mandrel 5 of band nut between two open-end wrench sheet tail ends, screw mandrel termination 4 flexibly connects with arm-tie, the arm-tie other end is bolted at back jig 10 1 ends, jig is loaded on the line end gold utensil after two, the middle part is provided with screw 12 on the back jig 10, nut 13, two ends are provided with trim ring 11, open-end wrench 1 opening part catches on the insulator cross-arm mid point bolt, existing instrument bottle supporting frame and arm-tie do not give in the drawings and draw and illustrate, because be the known instruments of present technique field personnel.
The concrete using method of this cover instrument is to clamp spanner 1 and back jig 10 on the tetrad plate that is set in cross-arm side and lead side respectively, after the length of tightening up screw mandrel 5 shortening arm-ties, the power that insulator bore is transferred on the arm-tie gradually, three yoke plates of open-end wrench 1 drive cross-arm side are that middle mind-set insulator side direction rotates with the contact point of U type ring and spanner, in like manner back jig 10 also rotates to the insulator side, after making the distance at insulator two ends be decreased to insulator string to be relaxed state, insulator is more changed jobs by the bottle supporting frame.Only need two people during operation, a people is line end on line, and a people carries out the load tool combinations at the shaft tower end and connects the two insulator strings of replacing.
