Description
Technical field
Pinion and-rack releasing pulley belongs to the pay-off equipment technical field in Overhead Transmission Line Construction service work,
More particularly to a kind of pay-off equipment of Poling Construction unfolding grounded-line.
Background technology
All kinds of conducting wires of transmission line of electricity, ground wire（Including OPGW optical cables, ADSS optical cables etc.）Poling Construction, refer to by grounded-line by
The requirement of design drawing is set up in organize the work stood on mounted shaft tower.It is tight that overhead transmission line Poling Construction includes unwrapping wire
The work such as line, grounded-line connection, sag observation, attachment installation.
Poling Construction is divided into no-station pole canopy unwrapping wire by the force way of unfolding grounded-line（Also known as mop floor unwrapping wire）, tension stringing
And other payingoff constructions.Grounded-line maintenance includes replacing grounded-line, adjusts arc sag, directly in work such as grounded-line maintenance.
Releasing pulley must be used by unfolding grounded-line, need to be equipped with unlike material and diameter according to different grounded-line models
Releasing pulley just can guarantee grounded-line payingoff construction safety.
Since Poling Construction scene dispersibility is very big, therefore a large amount of releasing pulleys must be transported to each shaft tower position respectively
It puts, and is lifted on insulator chain（Or on ground wire string）.Carrying and Hoisting tackle can only use artificial carry.Therefore, unwrapping wire is slided
Vehicle accomplish as possible small, quality is small, be readily transported in the case of also to operate steadily, the specific requirements such as grind resistance coefficient is small.
The releasing pulley used at present is different-diameter and wheel groove shape as made of wire type and material requirements mostly
Releasing pulley.Especially novel conductive wire material（Such as carbon fiber composite core wire）, it is desirable that releasing pulley diameter it is bigger.It puts
Line coaster diameter is bigger, and weight is heavier, has accordingly increased the labor intensity and operating risk of construction personnel.And releasing pulley
Race effective rate of utilization it is extremely low, only wheel footpath is about 1/3 useful.
Invention content
The technical problems to be solved by the invention are to provide one kind can also reduce corresponding peace while human and material resources are saved
The pay-off equipment of operating efficiency is improved in full blast danger.
In order to solve the above technical problems, the technical solution adopted in the present invention：Pinion and-rack releasing pulley, including axis T
Type connecting plate, the T-shaped connecting plate of the first ship, the T-shaped connecting plate of second ship, rack-and-pinion chain belt, first gear, second gear, third gear and
Four gears；
The T-shaped connecting plate of axis include the first connecting hole for being opened of top, the second connecting hole that lower part is opened and horizontal through
The connecting shaft of second connecting hole；
The T-shaped connecting plate of first ship, the T-shaped link configuration of second ship is identical and is symmetricly set on the T-shaped connecting plate both sides of axis, and
The structure of the T-shaped connecting plate of one ship is：The connecting plate, the ship shape plate at middle part and the stent of bottom of third connecting hole are provided with including top,
It is spaced apart that there are four the gear shaft of first gear, second gear, third gear and the 4th gear is allowed to pass through in the ship shape plate
Axis hole, the first gear, second gear, third gear and the 4th gear connect in a manner that gear shaft passes through axis hole respectively
Between the T-shaped connecting plate of the first ship, the T-shaped connecting plate of second ship；
The rack-and-pinion chain belt is joined end to end, and the inner ring of rack-and-pinion chain belt successively by multiple racks by link
For the rack engaged with first gear, second gear, third gear and the 4th gear, outer ring is provided with one week for placing grounded-line
Race.
The first gear, the 4th gear structure are identical and are separately positioned on the both ends of ship shape plate, the second gear,
Three gear structures are identical and are disposed on the middle part of ship shape plate, and first gear, second gear, third gear and the 4th tooth
The top of wheel is concordant.
The second gear, third gear diameter be more than first gear, the 4th gear diameter.
The stent is two and is symmetricly set on the bottom of ship shape plate.
Bearing is equipped in the first gear, second gear, third gear and the 4th gear and across bearing
Gear shaft is provided with the screw thread of attaching nut in the end of gear shaft, and being equipped in the gear shaft end nut side prevents nut
The split pin fallen.
The screw thread of attaching nut is provided at the both ends of the connecting shaft, and being equipped in nut side prevents nut from falling
Split pin.
Compared to the prior art the present invention has the advantages that.
First, the side that the present invention is engaged by first gear, second gear, third gear, the 4th wheel and rack formula chain belt
Formula is driven the rack-and-pinion chain belt that race places conducting wire, since it uses gear, rack structure, so stable drive is efficient,
Again since the connection of gear and axis uses bearing, so low friction resistance coefficient can effectively be dropped, unwrapping wire efficiency is improved.
2nd, the present invention is less than second gear, the in the middle part of ship shape plate due to ship shape plate both ends first gear, the 4th gear diameter
Three gear diameters, therefore the rack-and-pinion chain belt engaged with first gear, second gear, third gear, the 4th gear was rotating
With regard to that can remain shape of the both ends for overhanging corner in journey, grounded-line can preferably be protected not to be damaged in unwrapping wire process in this way
Wound.
