Abstract
The invention discloses a clamp for replacing a glass insulator for a power transmission line. The clamp is provided with two hooks and is characterized in that the hooks are of a hollow spindle shape; a fastening bolt is arranged on one side of each hook; connecting plates are respectively arranged at two ends of each hook; a connecting hole is formed in each connecting plate; a thread bush is arranged in each connecting hole; and a screw rod is arranged between every two corresponding thread bushes. Compared with a chain block, the clamp disclosed by the invention has the advantages of no cumbrous chains, light quality and convenience in carrying. The hooks which are of the hollow spindle shape are arranged and matched with a nut of the glass insulator, so that when the clamp is in use, the nut of the glass insulator is sleeved by the hooks; the nut of the glass insulator can be locked by rotating the hooks without slipping off; the steps are simple; and the labor intensity of workers is reduced. The two hooks are tightened by adopting the screw rods, so that the work can be finished by one worker and the labor force is further saved; and the operation can be finished without the matching of two persons at one time, and thus the work efficiency is greatly increased.
Description
Technical field
The transmission line that the present invention relates to use in a kind of circuit upkeep operation is changed the glass insulator jig.
Background technology
Glass insulator in use might be revealed, and the glass insulator that self-destruction takes place must in time be changed.At present, the mode of replacing glass insulator is: hook with the nut of two chain blocks with two glass insulators, spur to take off glass insulator to the centre.
The defective of the method for this replacing glass insulator is:
1, because the chain block quality is big, chain is long not portable.
2, because the nut of chain block front end hook and glass insulator does not match, waste time and energy during hook, and usually the situation that hook comes off takes place, the duplication of labour, staff's labour intensity is big.
When 3, changing, need two people simultaneously chain block to be drawn to the centre, waste of manpower, and two people are difficult for cooperating inefficiency.
Summary of the invention
The technical problem to be solved in the present invention provides 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 present invention 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, side at hook is provided with fastening bolt, two ends at hook are respectively equipped with connecting plate, are provided with a connecting hole at each connecting plate, and plane, described connecting hole place is vertical mutually with the large end face of hook, be provided with thread bush in the described connecting hole, between the thread bush of two correspondences, be respectively equipped with leading screw.
Described hook is made of main hook body, hook lock dog and screw, and the two ends of described hook lock dog are connected with the main hook body by screw respectively, described main hook body, links up with lock dog and surrounds spindle, in order to when problems such as generation is stuck opening of hook is taken off.
Described connecting plate is positioned at main hook body both sides.
The rotation direction of the thread bush internal thread of described two hook correspondence positions is opposite.
The invention has the beneficial effects as follows:
1, compare with chain block, the present invention does not have burdensome chain, and quality is light, be easy to carry.
2, owing to be 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 adopt leading screw to tighten up two hooks, a staff can finish, and saves manpower, need not two people and cooperates, and once finishes, and operating efficiency improves greatly.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: hook 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 is made 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, be respectively equipped with connecting plate 101a at the two ends of the main hook body 101 of hook 1, be provided with a connecting hole 101b at each connecting plate 101a, plane, described connecting hole 101b place is vertical mutually with the large end face of linking up with 1.Be provided with thread bush 3 in the 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 opposite.
During use, with the nut that two hooks 1 entangle two adjacent glass insulators respectively, Rotary hanging hook 1 makes hook 1 block the nut of 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 opposite, at this moment, two thread bushs 3 drive two hooks 1 and shrink to the centre.Pulling glass insulator in the middle of the hook 1, the clamp of the glass insulator that is used for being installed unclamps, and the staff upwards lifts, and can take off glass insulator.
Claims (4)
