Description
Technical field
This utility model belongs to electric stringing technical field, specifically, particularly relates to a kind of aerial earth wire hoisting tool.
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 aerial earth wire hoisting tool, its simple in construction, it is simple to
Fold, carry and construction operation is convenient, improve work efficiency, greatly reduce operating risk.
Described aerial earth wire hoisting tool, including tooth bar, tooth bar top is hinged with plural hoisting frame, bottom hoisting frame
Being provided with hoist hook, tooth bar is provided with sliding sleeve and fixed pedestal, fixed pedestal be respectively provided on two sides with draw-in groove and gear, in gear
Mandrel is provided with handle, and sliding sleeve is hinged with support bar, and support bar is hinged with hoisting frame.
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, easily realizes the up and down motion of tooth bar by rotating gear, 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, this utility model increases stress point, is exaggerated the scope of operation, and 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, fixed pedestal；3, support bar；4, hoist hook；5, draw-in groove；6, sliding sleeve；7, tooth bar；
8, gear；9, handle.
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, aerial earth wire hoisting tool, including tooth bar 7, tooth bar 7 top is hinged with plural hoisting frame 1,
Being provided with hoist hook 4 bottom hoisting frame 1, tooth bar 7 is provided with sliding sleeve 6 and fixed pedestal 2, being respectively provided on two sides with of fixed pedestal 2
Draw-in groove 5 and gear 8, the central shaft of gear 8 is provided with handle 9, and sliding sleeve 6 is hinged with support bar 3, support bar 3 and lifting
Frame 1 is hinged；Described hoisting frame 1 is 0-75 ° with the angle a of vertical direction.
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, is blocked by the draw-in groove 5 on fixed pedestal 2 and hang in transmission line tower,
Aerial earth wire set hangs on hoist hook 4, by handle 9, rotates counterclockwise gear 8, thus band carry-over bar 7 declines, due to cunning
Set 6 is blocked, and hoisting frame 1 is propped up by support bar 3, and aerial earth wire is raised by hoist hook 4, time saving and energy saving, convenient stand
Vacant lot line overhauls, and this utility model easily realizes lifting and the loose ends of aerial earth wire, and conveniently folds, carrying portable, more
Safe and reliable.
