Abstract
The utility model discloses a kind of automatic counting releasing pulley, including：Support bar, fixing axle, bearing, pulley and mechanical counter；The automatic releasing pulley that counts of the present utility model can guarantee that wire and pulley synchronous axial system, avoids the occurrence of slip frottage, reduces the abrasion to wire；By the addition of mechanical counter, the length of laying wire is calculated using the turnning circle write down, and sag size can accurately be calculated according to span, drainage equidimension, solves influence of the weather conditions to accuracy of measurement.
Description
Technical field
The utility model belongs to overhead transmission line field of engineering technology, more particularly to a kind of automatic counting releasing pulley.
Background technology
At present, in the wire erection link of overhead transmission line engineering, generally require by releasing pulley laying wire.Due to weight
The effect of power, wire can produce a certain degree of sag.According to the regulation of power circuit operating standard, wire must be protected with ground
Demonstrate,prove certain safe distance, it is therefore desirable to which staff strictly controls the lay length of every grade of wire, so should during laying
The sag of complete coverage wire.
However, because haze now and extreme weather are further frequent, the method for visualization measurement is difficult to accurately determine arc
Vertical size, it can not ensure that the safe distance of wire over the ground meets regulation, so as to leave potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of automatic counting releasing pulley.
Therefore, technical solutions of the utility model are as follows：
A kind of automatic counting releasing pulley, including：Support bar, fixing axle, bearing, pulley and mechanical counter；
Wherein, fixing axle is horizontally disposed with, and axle center is fixed on the middle part of support bar, and fixation is more on the outer circle wall of fixing axle
Individual bearing, the centre bore of pulley are enclosed on the outer circle wall of multiple bearings；A plectrum is provided with the side wall of pulley；
Mechanical counter is fixed on support bar using a connecting rod, and mechanical counter is provided with one close to plectrum
Contact；Make fixing axle per revolution, plectrum can be in contact rear mechanical counter with the contact of mechanical counter once
Count once.
The outer circle wall of pulley is provided with silicone rubber coating.
Mechanical counter is provided with display screen, the numerical value of energy display counting.
Compared with prior art, the automatic releasing pulley that counts provided by the utility model can guarantee that synchronous with pulley turn of wire
It is dynamic, slip frottage is avoided the occurrence of, reduces the abrasion to wire；By the addition of mechanical counter, the turning collar write down is utilized
Number calculates the length of laying wire, and can accurately calculate sag size according to span, drainage equidimension, eliminate weather because
Influence of the element to accuracy of measurement.
Brief description of the drawings
Fig. 1 is the automatic structural representation for counting releasing pulley of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model, but following embodiments are right absolutely not
The utility model has any restrictions.
As shown in figure 1, the automatic counting releasing pulley includes：Support bar 5, fixing axle 3, bearing 2, pulley 1 and machinery meter
Number device 6；
Wherein, fixing axle 3 is horizontally disposed, and axle center is fixed on the middle part of support bar 5, solid on the outer circle wall of fixing axle 3
Fixed multiple bearings 2, the centre bore of pulley 1 are enclosed on the outer circle wall of multiple bearings 2；One is provided with the side wall of pulley 1 to dial
Piece 8；
Mechanical counter 6 is fixed on support bar 5 using a connecting rod, and mechanical counter 6 is provided with one close group
The contact 7 of piece 8；Make the per revolution of fixing axle 3, plectrum 8 can contact once with the contact 7 of mechanical counter 6, after being in contact
Mechanical counter 6 counts once.
The outer circle wall of pulley 1 is provided with silicone rubber coating 4.
Mechanical counter 6 is provided with display screen, the numerical value of energy display counting.
Now the automatic operation principle for counting releasing pulley of the present utility model is described below：
When carrying out conductor laying, first by the automatic steel tower for counting releasing pulley and being fixed on erection wire of the present utility model
On, then wire is wound on the silicone rubber coating 4 of pulley 1, the initiating terminal alignment plectrum 8 of wire；Plectrum 8 is turned into machinery
At the contact 7 of counter 6, start counting up：Because the frictional force of silicone rubber coating 4 is larger, therefore pulley 1 synchronous with wire can turn
Dynamic, the per revolution of pulley 1, plectrum 8 will occur once to contact with contact 7, and mechanical counter 6 counts once.According to advance
The length of wire needed for calculating, and the number of turns of pulley 1 is converted into, when mechanical counter 6 shows the calculated number of turns, stop
Only unwrapping wire, you can ensure the accuracy of conductor length, so that it is guaranteed that the safe distance of conducting wire sag over the ground.
