Description
Technical field
This utility model belongs to electric stringing technical field, specifically, particularly relates to a kind of adjustable overhead-groundwire lifter.
Background technology
Aerial earth wire is the important component part of high voltage transmission line line structure, owing to transmission line of electricity to cross over wide region, at thunder
It is subject to thunderbolt rainy season and causes power transmission to interrupt, become the one of the main reasons that power outage occurs.Aerial earth wire is all frame
Being located at the top of high-voltage transmission line pole tower, in thunderstorm weather, first lightning passage hits aerial earth wire, makes lightning current
Enter the earth, to protect the normal power transmission of wire, therefore, aerial earth wire is installed and can reduce lightening hazard, improve what circuit ran
Safety.Existing overhead ground wire lifting device simple in construction, stress point is few, scope of operation relatively narrower, and construction operation is relatively cumbersome,
Conventional service kit is heavier, and upper and lower transmission brings very big inconvenience, and the dangerous spot of generation is the most, and aerial earth wire support
Stress point selects less, and cross-arm is easily generated deformation, causes equipment deficiency and potential safety hazard；Meanwhile, in work high above the ground overlong time,
Bring higher risk to operation, even cause casualties.
Summary of the invention
The purpose of this utility model is to overcome drawbacks described above, it is provided that a kind of adjustable overhead-groundwire lifter, its simple in construction,
Carrying portable, operation face width, the convenient gradient regulating aerial earth wire, improve work efficiency.
Described adjustable overhead-groundwire lifter, including screw mandrel, screw mandrel top is fixed with hook, and screw mandrel top is hinged with two
Individual above hoisting frame, is provided with hoist hook bottom hoisting frame, screw mandrel is provided with sliding sleeve and silk is pulled, and silk is pulled and is provided with handle, sliding sleeve
On be hinged with adjustable support bar, support bar is hinged with hoisting frame.
Further, described support bar includes that the threaded rod that two hand of spirals are contrary, two threaded rods pass through sleeve connection.
Further, described hoisting frame is " n " type structure, and hoist hook is hinged with hoisting frame by bolt.
Further, described hoisting frame is 0 75 ° with the angle a of vertical direction.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model simple in construction, construction operation is convenient, is easily realized the up and down motion that silk is pulled by swing handle, thus
Drive sliding sleeve moves up and down, and is realized the motion of hoisting frame by support bar, thus completes the lifting operation of ground wire, convenient and swift；
2, stress point of the present utility model is many, is exaggerated the scope of operation, by sleeve and two shaft, adjusts the length of support bar
Degree, thus regulate the angle of inclination of aerial earth wire, workman's construction is more time saving and energy saving；
3, this utility model is collapsible, carrying portable, simple to operate, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation that hoist hook coordinates with hoisting frame.
In figure, 1, hoisting frame；2, hook；3, support bar；4, hoist hook；5, sliding sleeve；6, silk is pulled；7, screw mandrel；8、
Handle；9, threaded rod；10, sleeve.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, adjustable overhead-groundwire lifter, including screw mandrel 7, screw mandrel 7 top is fixed with hook 2, screw mandrel 7
Top is hinged with plural hoisting frame 1, is provided with hoist hook 4 bottom hoisting frame 1, and screw mandrel 7 is provided with sliding sleeve 5 and silk pulls 6,
Silk is pulled 6 and is provided with handle 8, and sliding sleeve 5 is hinged with adjustable support bar 3, and support bar 3 is hinged with hoisting frame 1；Described
Strut 3 includes that the threaded rod 9 that two hand of spirals are contrary, two threaded rods 9 are connected by sleeve 10；Described hoisting frame 1 is with vertical
The angle a in direction is 0 75 °.
As in figure 2 it is shown, described hoisting frame 1 is " n " type structure, hoist hook 4 is hinged with hoisting frame 1 by bolt.
As it is shown in figure 1, this utility model is in use, hanging in transmission line tower by hook 2 card, aerial earth wire set hangs over
On hoist hook 4, swing handle 8, operate silk and pull 6 risings, thus drive sliding sleeve 5 to rise, hoisting frame 1 is supportted by support bar 3
Rising, aerial earth wire is raised by hoist hook 4, time saving and energy saving, facilitates aerial earth wire to overhaul；This utility model is easily real
The lifting of existing aerial earth wire and loose ends, and be easy to fold, carrying portable, safety and reliability.When needing to regulate inclining of aerial earth wire
During rake angle, only need to rotate the sleeve 10 of side, be coordinated with two threaded rods 9 by sleeve 10, adjust the length of support bar 3
Realize.
