Description
Technical field
The invention belongs to power construction pulley technical field, electric power lifting is in particular related to from stop fixed pulley and is used
The method that the fixed pulley lifts article.
Background technology
In power construction or maintenance process, it is often necessary to which the instrument being located at below transmission tower or line bar or workpiece are transported to
In transmission tower, method of shipment mainly using fixing fixed pulley above transmission tower, then by underlying personnel by instrument or workpiece
Pulled on by the rope for bypassing fixed pulley.It is main to make workpiece using two methods after workpiece or instrument reach specified location
Or instrument rests on specified location：First, underlying operating personnel are always with rope is pulled, not only labour intensity is big,
And increased human cost；Second, cable end is bundled in into line bar or transmission tower root, so, operating personnel can unclamp rope
Rope, is engaged in other work, but so not only time-consuming, and when workpiece is easily caused or instrument falls after rope loosening, produces
It is raw dangerous.
The content of the invention
First technical problem that the present invention is solved just be to provide it is a kind of it is easy to operate, can at any time automatically by workpiece or work
The electric power that tool stops at an arbitrary position is lifted from stop fixed pulley.
In order to solve the above technical problems, technical scheme proposed by the present invention is：Including the pulley yoke with hook, described
It is provided with pulley yoke with fluted pulley, the pulley yoke upper side is provided with inverse u shape support frame, support frame as described above
Including upper plate and two side shields, the lower end of support frame as described above is fixed with the pulley yoke lower end and is intersected with the pulley yoke
Certain angle, through hole is provided with support frame as described above upper plate, and expansion link is provided with the through hole, under the expansion link
End is provided with wheel fork, compression top spring is provided between the wheel fork upper end of the expansion link and the upper plate, on the wheel fork
The braked wheel with axis is provided with, the braked wheel is inserted in the groove of the pulley, on the side shield of support frame as described above
It is provided with along side shield direction, the groove with one fixed width, the axis two ends are located in the groove；In the side shield
The axis correspondence position is provided with annulus away from pulley yoke side, be installed with end in the annulus is fixedly connected with axis
Spacing drawstring.
Its additional technical feature is：
The pulley yoke lower end is provided with " U " type clamping plate, the clamping plate lower end is provided with fastening bolt.
Second technical problem that the present invention is solved just is to provide a kind of lifting using above-mentioned electric power and is carried from stop fixed pulley
The method for rising article.
In order to solve the above technical problems, technical scheme proposed by the present invention is：
The method comprises the following steps：
The first step, fixed block
Hook is suspended on steel wire or cross-arm；
Second step, pulley is passed through by with items of rope one end
The free end that one end is fastened the rope of article is placed in groove from away from support frame side through pulley, by
In groove away from pulley yoke side, be pressed in rope axle position between braked wheel and pulley by upward top pressure compression top spring, and by rope
Free end deliver to ground；
3rd step, the free end of downward tow
The free end of downward tow, in the presence of rope frictional force and compression top spring, axis is located at groove away from cunning
Wheel carrier side, article rises with rope；
4th step, stops downward tow
When article reaches specified location, stop downward tow, come up rope, rope drives in the gravity of article
Lower to be slided to opposite direction along pulley, now, in the presence of frictional force, rope drives axis lateral away from pulley yoke one from groove
The side shifting of pulley yoke one, during movement, due to the top pressure by pulley, expansion link is moved axis along through hole, compression top spring,
Top pressure with compression top spring deforms, and the pressure between braked wheel and rope is increasing, until rope stops movement；
5th step, construction
Top-operation personnel are constructed after article stops to specified location；
6th step, article is sent back to
Spacing drawstring is pulled, axis is returned to groove away from pulley yoke side, braked wheel is substantially reduced with the pressure of rope,
Its frictional force is also decreased, and in the presence of article gravity, article drives rope to return to ground.
Its additional technical feature is：
When the height that the 4th step rises to article is higher than specified location, spacing drawstring is pulled, return to axis logical
Groove is substantially reduced away from pulley yoke side, braked wheel with the pressure of rope, and its frictional force is also decreased, in the work of article gravity
Under, article drops down onto specified location under driving rope automatic, then unclamps spacing drawstring, and the rope that comes up.
The method that the electric power lifting that the present invention is provided lifts article from stop fixed pulley and using the fixed pulley, compared with skill
Art compares with advantages below：First, due to including the pulley yoke with hook, being provided with ditch on the pulley yoke
The pulley of groove, inverse u shape support frame is provided with the pulley yoke upper side, and support frame as described above includes upper plate and two side blocks

State axis correspondence position and be provided with annulus, the spacing drawstring that end is fixedly connected with axis is installed with the annulus, when using,
The free end that one end is fastened the rope of article is placed in groove from away from support frame side through pulley, axis is located at logical
Away from pulley yoke side, be pressed in rope groove between braked wheel and pulley by upward top pressure compression top spring, and by the free end of rope
Deliver to ground；The free end of downward tow, in the presence of rope frictional force and compression top spring, axis is located at groove away from cunning
Wheel carrier side, article rises with rope；When article reaches specified location, stop downward tow, come up rope, rope
Rope is slided along pulley in the case where the gravity of article drives to opposite direction, and now, in the presence of frictional force, rope drives axis from logical
Groove away from the lateral side shifting of pulley yoke one of pulley yoke one, axis during movement, due to the top pressure by pulley, expansion link edge
Moved on through hole, compression top spring, the top pressure with compression top spring deforms, and the pressure between braked wheel and rope is increasing, until
Rope stops movement；After the completion of construction, pull spacing drawstring, axis is returned to groove away from pulley yoke side, braked wheel with
The pressure of rope is substantially reduced, and its frictional force is also decreased, and in the presence of article gravity, article drives rope to return to ground
Face, using more facilitating, and personnel take few, and human cost is substantially reduced；When article is lifted beyond specified location, pull
Spacing drawstring, makes axis return to groove away from pulley yoke side, and braked wheel is substantially reduced with the pressure of rope, its frictional force also with
Reduction, in the presence of article gravity, article drive rope it is automatic under drop down onto specified location, then unclamp spacing drawstring, and
Come up rope, using more convenient；Second, due to being provided with " U " type clamping plate in the pulley yoke lower end, in the clamping plate
