Abstract
The utility model provides a fixture for replacing a glass insulator of a transmission line, and the fixture comprises two hooks. The fixture is characterized in that each hook is in a hollow spindle shape, one side of each hook is provided with a fastening bolt, two ends of each hook are respectively provided with connecting plates, each connecting plate is provided with a connecting hole, a threaded bush is arranged in the connecting hole, and a leading screw is arranged between each two corresponding threaded bushes. Compared with a chain block, the fixture for replacing the glass insulator of the transmission line is advantaged by no cumbersome chain, light weight, and portability. Since the hollow spindle-shaped hooks are provided and fit with nuts of the glass insulator; when the fixture is used, the nuts of the glass insulator are sleeved, the nuts of the glass insulator can be locked by rotating the hooks, and the glass insulator fails to slip; and the steps are simple, and the labor intensity of staff is reduced. Since the leading screws are employed to tighten the two hooks, only one personnel is needed to accomplish the work, the manpower is reduced, two-people cooperation is not needed, the work can be done at one time, and the work efficiency is significantly improved.
Description
Technical field
The utility model relates to the transmission line used in a kind of circuit upkeep operation and changes the glass insulator jig.
Background technology
Glass insulator in use likely can be revealed, and the glass insulator that self-destruction occurs must be changed in time.At present, the mode of replacing glass insulator is: with two chain blocks, the nut of two glass insulators is hooked, pull to take off glass insulator to centre.
The defect of the method for this replacing glass insulator is:
1, because the chain block quality is large, chain is long not portable.
2, because chain block front end hook and the nut of glass insulator do not mate, during hook, waste time and energy, and usually the situation that hook comes off occurs, the duplication of labour, staff's labour intensity is large.
While 3, changing, need two people chain block to be drawn to centre simultaneously, waste of manpower, and two people are difficult for cooperation, inefficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly is easy to carry, time saving and energy saving, intensity of workers is low, the transmission line of high efficiency is changed the glass insulator jig.
The utility model is achieved in that
A kind of transmission line is changed the glass insulator jig, two hooks are arranged, its special character is: described hook is the hollow spindle, a side at hook is provided with fastening bolt, two ends at hook are respectively equipped with connecting plate, are provided with a connecting hole on each connecting plate, and plane, described connecting hole place is mutually vertical with the large end face of hook, be provided with thread bush in described connecting hole, between the thread bush of two correspondences, be respectively equipped with leading screw.
Described hook consists of main hook body, hook lock dog and screw, the two ends of described hook lock dog are connected with the main hook body by screw respectively, described main hook body, hook lock dog surround spindle, described connecting plate is positioned at main hook body both sides, in order to when the problem such as stuck occurs, opening of hook is taken off.
The rotation direction of the thread bush internal thread of described two hook correspondence positions is contrary.
The beneficial effects of the utility model are:
1, with chain block, compare, the utility model is without burdensome chain, and quality is light, be easy to carry.
2, owing to being provided with hollow spindle hook, with the nut coupling of glass insulator, during use, the nut of glass insulator is entangled, Rotary hanging hook, can pin the nut of glass insulator, can slippage, step is simple, has alleviated staff's labour intensity.
2, owing to adopting leading screw to tighten up two hooks, a staff can complete, and saves manpower, without two people, coordinates, and once completes, and operating efficiency improves greatly.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
In figure: link up with 1, main hook body 101, connecting plate 101a, connecting hole 101b, hook lock dog 102, screw 103, fastening bolt 2, thread bush 3, leading screw 4.
Embodiment
As shown in the figure, this transmission line is changed the glass insulator jig two hooks 1.In the present embodiment, described hook 1 consists of main hook body 101, hook lock dog 102 and screw 103, the two ends of described hook lock dog 102 are connected with main hook body 101 by screw 103 respectively, and described main hook body 101, hook lock dog 102 surround the hollow spindle.Be provided with fastening bolt 2 in a hook side of 1, at the two ends of the main hook body 101 of hook 1, be respectively equipped with connecting plate 101a, be provided with a connecting hole 101b on each connecting plate 101a, plane, described connecting hole 101b place is mutually vertical with the large end face of linking up with 1.Be provided with thread bush 3 in described connecting hole 101b, between the thread bush 3 of two correspondences, be respectively equipped with leading screw 4.The thread rotary orientation of the thread bush 3 of described two correspondences is contrary.
During use, the nut that two hooks 1 are entangled respectively to two adjacent glass insulators, Rotary hanging hook 1, make to link up with 1 nut that blocks glass insulator.Penetrate leading screw 4, and rotating threaded shaft 4, because the thread rotary orientation in the thread bush 3 of two correspondence positions is contrary, now, two thread bushs 3 drive two hooks 1 and shrink to centre.Hook pulls glass insulator in the middle of 1, for the clamp of the glass insulator that is installed, unclamps, and the staff upwards lifts, and can take off glass insulator.
Claims (3)
1. a transmission line is changed the glass insulator jig, two hooks are arranged, it is characterized in that: described hook is the hollow spindle, a side at hook is provided with fastening bolt, two ends at hook are respectively equipped with connecting plate, be provided with a connecting hole on each connecting plate, in described connecting hole, be provided with thread bush, between the thread bush of two correspondences, be respectively equipped with leading screw.
