Abstract
The utility model discloses an overhead ground wire lifter, which consists of a horizontal support and two wire lifting hooks. The bottom of the middle of the horizontal support is provided with a longitudinal positioning clamp slot. Two telescopic straight rods are penetratingly arranged on two sides of the horizontal support, and one end of each telescopic straight rod is provided with threads. The two telescopic straight rods are symmetrically arranged on two sides of the longitudinal positioning clamp slot. A retaining plate is arranged at the other ends of the telescopic straight rods. Barrels are assembled with the threaded sections of the telescopic straight rods on the upper portion of the horizontal support. Ratchet levers are fixedly mounted on the barrels. One end of each wire lifting hook is a loop, the other end thereof is a hook body, and the inner diameter of the loop is smaller than the diameter of the retaining plate on the telescopic straight rods. The two wire lifting hooks are respectively sleeved at the other ends of the telescopic straight rods through the loops. The overhead ground wire lifter is scientific and reasonable in structural design, simple in operation, flexible in use, safe and reliable. Maintenance can be completed easily by one operator, work efficiency can be improved greatly and labor intensity of operators is reduced.
Description
Technical field
The utility model belongs to electric power maintenance tool technical field, especially relates to a kind of overhead ground wire line lifter.
Background technology
Along with the growth of the circuit operation time limit, the sprung parts defective of overhead ground wire hitch point is also following.In the past; Carrying out the aerial condutor maintenance when (as changing wire clamp, changing aerial condutor); Need overhead ground wire be mentioned, the method for use generally is by one or two human shoulder overhead ground wire to be lifted with hands, carries out upkeep operation by other people then; This mode labour intensity is big, especially is absolutely unsafe; In addition, also can adopt the anti-formula of existing shoulder to carry the Line tool for common line, utilize the double hook wire grip that ground wire is mentioned, but for 500 KVs, its cross section, ubiquity bottom surface is big, retaining is apart from characteristics such as long, ground wire hanging point and the increasings of lead cross-arm.The anti-formula of existing shoulder is proposed the user demand that the Line tool can't satisfy the maintenance of 500 KV sprung partses, therefore can't in time handle the existing defective of the sprung parts of its hitch point, just can keep in repair, and waste time and energy in the time of can only having a power failure by the time usually.In case component defect is comparatively serious, then must apply for unplanned power failure, it will inevitably cause the certain economic loss.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of simple in structure, easy to use, time saving and energy saving overhead ground wire line lifter.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of overhead ground wire line lifter; It is made up of horizontal shore and two thread-lifting hooks, and lower bottom part offers a longitudinal register draw-in groove in the middle of the said horizontal shore, and the both sides on horizontal shore are equipped with the screwed telescopic straight-bar of an end respectively; And two telescopic straight-bar symmetries are positioned at the both sides of longitudinal register draw-in groove; The end of the other end of telescopic straight-bar is provided with baffle plate, is positioned on the thread segment of telescopic straight-bar of horizontal shore upper position all to be fitted with swivel nut, all is fixed with ratchet wrench on the swivel nut; One end of said thread-lifting hook is the collar, and the other end is a coupler body, and the internal diameter of the collar is less than the diameter of the baffle plate on the telescopic straight-bar, and two thread-lifting hooks are sleeved on the other end of telescopic straight-bar respectively through the collar.
Described overhead ground wire line lifter is equipped with limiting plate on the baffle plate of its two telescopic straight-bars, the inwall contact of the coupler body that the other end of limiting plate is corresponding with it.
Described overhead ground wire line lifter, the hinged extension bar that is equipped with in the end of its ratchet wrench.
Owing to adopt technique scheme, the utlity model has following superiority:
1, the utility model overhead ground wire line lifter is loaded on the steel plate of head of mast through the horizontal shore locator card; The turn ratchet wrench makes the swivel nut rotation during use, vertically rises thereby drive thread-lifting hook, and the thread-lifting hook bottom is colluded and tangled ground wire; The purpose that breaks away from sprung parts is lifted ground wire in realization; Under charged situation, can change or keep in repair the sprung parts of hitch point like a cork, thereby reduce the unplanned frequency of power cut of circuit, improve the business economic benefit.
2, the hinged extension bar that is equipped with in the ratchet wrench end of the utility model overhead ground wire line lifter, extension bar and ratchet wrench level can apply torsion turn swivel nut in the use, and then drive the thread-lifting hook up-down; When not using, extension bar can vertically rotate, so that take in, carry.
3, the utility model overhead ground wire line lifter scientific structure design is reasonable; Have advantages such as volume is little, in light weight, portable, simple to operate, use is flexible, safe and reliable; Can comparatively easily accomplish maintenance work by a staff; Can increase substantially operating efficiency, reduce intensity of workers.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-horizontal shore; The 2-draw-in groove; The 3-swivel nut; The 4-ratchet wrench; The 5-extension bar; The 6-telescopic straight-bar; The 7-thread-lifting hook; The 8-limiting plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
In conjunction with Fig. 1; This overhead ground wire line lifter; It is made up of horizontal shore 1 and two thread-lifting hooks 7, and lower bottom part is shaped on a longitudinal register draw-in groove 2 in the middle of the said horizontal shore 1, and the both sides on horizontal shore are equipped with the screwed telescopic straight-bar 6 of an end respectively; And two telescopic straight-bar 6 symmetries are positioned at the both sides of longitudinal register draw-in groove; The end of the other end of telescopic straight-bar 6 is provided with baffle plate, on the thread segment of the telescopic straight-bar of horizontal shore 1 upper position, all is fitted with swivel nut 3, all is fixed with ratchet wrench 4 on the swivel nut 3; One end of said thread-lifting hook 7 is the collar, and the other end is a coupler body, and the internal diameter of the collar is less than the diameter of the baffle plate on the telescopic straight-bar, and two thread-lifting hooks 7 are sleeved on the other end of telescopic straight-bar 6 respectively through the collar; Be equipped with limiting plate 8 on the baffle plate of said two telescopic straight-bars 6, the inwall contact of the coupler body that the other end of limiting plate 8 is corresponding with it, the setting of limiting plate 8 can prevent effectively that the ground wire in the coupler body from skidding off; The hinged extension bar 5 that is equipped with in the end of said ratchet wrench 4 is convenient to rotary threaded sleeve, has reduced labour intensity.
When using the overhead ground wire line lifter of the utility model, horizontal support is placed on the steel plate of head of mast, and through vertical draw-in groove location.Thread-lifting hook hook residence line rotates swivel nut through the turn ratchet wrench, thereby the telescopic straight-bar that drives in the swivel nut rises, and realizes circuit is lifted the disengaging hanger bracket.Under the charged situation of circuit, can change or keep in repair the sprung parts of hitch point thus like a cork.After treating that the sprung parts maintenance is accomplished, extension bar on the adjustment ratchet wrench, the backward rotation ratchet wrench can vertically descend telescopic straight-bar, and circuit is positioned on the suspension, accomplishes maintenance work.
