Abstract
The utility model relates to a portable paying-off tackle, and the structure of the paying-off tackle is that a pulley support is provided with a pulley block which at least comprises two pulleys; the wheel diameters of the pulleys are different; shafts of the pulleys of the pulley block are located on arc lines with the same radius; and the top of the pulley support is connected with a connecting hook through a connecting plate. According to the utility model, the size of a main body is changed from a whole circumference in the prior art to the maximum 120-degree arc, and also is reduced by three fourths. Moreover, the weight of the main body is reduced by more than one second, thereby achieving an effect of yielding twice the result with half the effort for the tensioning and paying-off construction of a power line. In addition, the paying-off tackle is simple and flexible in operation, is convenient to use, can be operated by a single person, greatly improves the work efficiency, reduces the labor intensity of a worker, reduce the cost of operation, is simple in structure, is high in practicality, is safe and reliable, is lower in cost, can be widely used in the paying-off construction of a power transmission line, and is very high in values of popularization and application.
Description
Technical field
The utility model relates to a kind of electric power system paying-off implement, relates in particular to a kind of lightweight releasing pulley, is applicable to the tight unwrapping wire of power line construction.
Background technology
At present the tight unwrapping wire of power circuit will be selected according to wire diameter the wheel footpath of coaster with common block, and along with the wheel footpath of the increase coaster of wire diameter also increases, volume also increases thereupon, large releasing pulley volume is large, heavy, carrying inconvenience, often needs to employ hoisting equipment, very inconvenient.And for different wire diameters, need to prepare multiple coaster of taking turns footpath, not only increased cost, and complex operation, efficiency of construction is low.Meanwhile, also only have 1/3rd of pulley girth when the contact length of pulley and wire is maximum, the part not reaching, all in idle running, not only consumes energy, and has extended the work period.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of lightweight releasing pulley, has solved the problem that in prior art, jig can not be general.
Technical solutions of the utility model are as follows:
Assembly pulley is set on pulley bracket, at least comprises two pulleys in assembly pulley, not etc., the pulley spindle of each pulley in assembly pulley is not on the circular arc line of same Radius in the wheel footpath of each pulley in assembly pulley; The top of pulley bracket is by connecting plate coupling hook.
Described pulley bracket consists of two symmetrically arranged arc plates, and the both sides up and down of monolithic arc plate are isocentric circular arc.
Described assembly pulley is arranged between two arc plates.
It is 120 degree that described assembly pulley forms maximum angle.
The base of described connecting plate is connected with pulley bracket axle, and the top of connecting plate is flexibly connected hook by bolt.
Described connecting plate is ladder type.
The utility model compared with prior art, has following effect:
1, the utility model becomes body volume into maximum 120 degree angle circular arcs by whole circumference of the prior art, volume reduces 3/4ths, weight saving is over half, the tight payingoff construction of power circuit is played a multiplier effect, convenient and flexible operation, easy to use, single can operation, significantly improve operating efficiency and alleviated operating personnel's labour intensity, reduced this achievement of operating cost simple in structure, practical, safe and reliable, and cost is lower, can extensive use in power transmission sequence payingoff construction, there is very strong application value.
2, simultaneously due to the wheel footpath of pulley not etc., contact with wire, during wire bending, to guarantee the requirement of different-diameter wire to sheave footpath, the scope of application is wide.
3, connecting plate adopts ladder type, stable connection, and also connecting plate is connected with pulley bracket axle, is flexibly connected with hook bolt, and for convenience detach, maintenance replacing facilitates.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the side structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of assembly pulley.
In figure, 1, hook, 2, connecting plate, 3, pulley bracket, 4, bolt, 5, pulley, 6, pulley spindle.
Embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, the utility model is elaborated as follows.
Embodiment
As Figure 1-3, pulley bracket 3 consists of two symmetrically arranged arc plates, the both sides up and down of monolithic arc plate are isocentric circular arc, one group of assembly pulley is set between two arc plates, assembly pulley comprises three pulleys 5, not etc., the pulley spindle 6 of three pulleys is not on the circular arc line of same Radius in the wheel footpath of three pulleys, and each pulley spindle is fixed on arc plate by bolt 4; The top of pulley bracket is provided with ladder type connecting plate 2, and the base of ladder type connecting plate is connected with pulley bracket axle, and the top of connecting plate is flexibly connected hook 1 by bolt, and hook is for being connected whole coaster with hanging point.
It is 120 degree that described assembly pulley forms maximum angle.
The quantity of described assembly pulley be take odd number as first-selected.
Hook of the present utility model adopts cast iron production machinery intensity high; Connecting plate employing general steel plate is made its intensity and is met payingoff construction requirement; Pulley adopts aluminium alloy to use machined into form, and also can adopt as requested the processing such as nylon, plastics.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within principle of the present utility model, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
