Description
Technical field
The utility model relates to high pressure overhead power line constructing device field, particularly, relates to a kind of light gauge wire pressing line pulley.
Background technology
At present, in domestic high pressure overhead power line engineering Poling Construction, there is no special wire pressing line pulley, the pressing line pulley of construction usage and releasing pulley were exactly the coaster of same specification in the past, and workmen is just different according to its purposes, titled with pressing line pulley and releasing pulley two kinds of appellations, releasing pulley is exactly the coaster of support wire or steel wire rope, its active force upwards, pressing line pulley exactly by wire or steel wire rope toward pressing down, its active force is downward.Usual 500kV high-tension line is divided into according to stringing stretching mode and leads two and one and lead 4 two kinds, and wire pressing line pulley adopts the releasing pulley of same specification usually, i.e. three-wheel and five skating cars.With the elegant cross-sectional area of 500kV for 725mm
2wire is example, and single five wheel line tackle overall heights are 1.7 meters, and wheel footpath reaches 916mm, and volume is large, highly high, is unfavorable for transport; And take turns footpath greatly because of it, the overall center of gravity of coaster is higher, and in use coaster is easily toppled over; Secondly, single five wheel line tackle weight reach 230kg, and weight is large, and at least 6-8 people could carry, and transports very difficult, at the scene in installation process, motor-driven grinding mill must be used to be promoted, install not only time and effort consuming, and be inconvenient to operate.
Utility model content
The utility model provides a kind of light gauge wire pressing line pulley to solve the problems of the technologies described above, and its volume is little, and be beneficial to transport carrying, it is convenient to install.
The technical scheme in the invention for solving the above technical problem is:
Light gauge wire pressing line pulley, comprise main shaft and the coaster support being fixed on main shaft two ends, the top of described coaster support is fixed with a boatswain chair, and described main shaft is provided with two pulleys, described spindle jacket is connected to bearing, and described pulley sleeve is connected on outside bearing.The utility model improves mainly for the pressing line pulley that leads four stringing modes.This wire pressing line pulley, mainly considers from line ball effect, is used as pressing line pulley specially.Lead in four stringing methods one, during every four root unfolding conductor mutually, adopt the pressing line pulley of two this programme.The pressing line pulley of this programme adopts the structure of two pulleys, and original 5 pulleys are reduced to 2, and the quantity of pulley reduces, the length of main shaft reduces, the volume and weight of pressing line pulley can be reduced, such that the volume of this pressing line pulley is less, weight is lighter, be convenient to install and transport.Its installation method is identical with the mounting means of the pressing line pulley of existing routine.Bearing is set between pulley and main shaft, is convenient to pulley rotation, strengthen and use simple operation sense.
As preferably, described main shaft is also socketed with multiple spacer outward, and described spacer comprises spacer sleeve and the avris spacer between pulley and coaster support between two pulleys.Be provided with spacer between pulley, between pulley and coaster support, pulley is not affected each other when rotating, also not by the impact of coaster support.
As preferably, described coaster support is provided with baffle plate, and described baffle plate is between boatswain chair and pulley.Utilize baffle plate to protect circuit, to avoid when line ball circuit and support at collision friction.
Further, described baffle plate is nylon baffle.Adopt nylon baffle, its rub resistance is good.
As preferably, described boatswain chair two ends are connected with coaster support by bolt.Adopt the connected mode of bolt, its structure is simple, and is convenient to the dismounting of boatswain chair.
As preferably, described main shaft is 40Cr alloy.
To sum up, the beneficial effects of the utility model are:
The utility model arranges two pulleys on main shaft, lead in four stringing methods one, the pressing line pulley of two this programme is adopted during every phase four root unfolding conductor, the quantity of its pulley reduced, also reduce the length of main shaft, make the volume of pressing line pulley less, weight is lighter, is convenient to install and transport.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1, coaster support; 2, boatswain chair; 21, bolt; 3, main shaft; 4, spacer; 5, baffle plate; 6, pulley; 7, bearing.
Embodiment
Below in conjunction with embodiment and accompanying drawing, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1:
This special pressing line pulley is the once innovation to high pressure overhead power line engineering construction facility, thus has filled up the blank of Electric Power Transmission & transformation Company without special wire pressing line pulley, and this meets the requirement of State Grid Corporation of China's " amphitypy three is new ".A kind of light gauge wire pressing line pulley as shown in Figure 1, comprise main shaft 3 and the coaster support 1 being fixed on main shaft 3 two ends, the top of described coaster support 1 is fixed with a boatswain chair 2, described main shaft 3 is provided with two pulleys 6, be socketed with bearing 7 outside described main shaft 3, described pulley 6 is socketed in outside bearing 7.Utilize bearing to realize the connection of pulley and main shaft, be conducive to the rotation of pulley.Because its volume reduces, weight saving, only need be pulled on steel tower with rope when installing at the scene just can light installation in position, without the need to using motor-driven grinding mill, installing very easy, not only saving time but also save trouble.Adopt this kind of structure, its main axis length reduces, and wheel footpath reduces, and the overall center of gravity of coaster reduces, thus solves the difficult problem that pressing line pulley easily topples over.
Embodiment 2:
A kind of light gauge wire pressing line pulley as shown in Figure 1, the present embodiment is optimized on the basis of above-described embodiment, namely described main shaft 3 is outer is also socketed with multiple spacer 4, and described spacer 4 comprises spacer sleeve and the avris spacer between pulley 6 and coaster support 1 between two pulleys 6.Spacer is set between pulley, makes to be not in contact with each other mutually between pulley, avoid pulley to influence each other in rotation process; Spacer is set between pulley and coaster support, pulley is not in contact with each other mutually with coaster support, avoid coaster rotation process to the wearing and tearing of support and coaster support to the impact of pulley.
Coaster support 1 is provided with baffle plate 5, described baffle plate 5 is between boatswain chair 2 and pulley 6.Baffle plate is arranged on the medial surface of coaster support 1.Baffle plate 5 is preferably chosen as nylon baffle, and its high-strength abrasion-proof is anti-aging.
Boatswain chair 2 two ends are connected with coaster support 1 by bolt 21.
Described main shaft 3 is 40Cr alloy.
Adopt this pressing line pulley, its sheave footpath is 215mm, and less than 1/4 of original wheel footpath 916mm, overall height is about 568mm, is 1/3 of original overall height 1700mm, thus make whole light-duty special pressing line pulley size, volume reduces greatly, transports very convenient.Also can adopt light-duty alloy material, as 40Cr alloy, cause coaster weight significantly to reduce, single coaster weight 20-23kg, be 1/10 of original single coaster weight, only needs a people just easily a special pressing line pulley can be transported to on-the-spot tower position.
As mentioned above, the utility model can be realized preferably.
