Abstract
The utility model relates to an upturned pulley for replacing a tension insulator, which is characterized by comprising a manual pulley (4); a fixed plate and a movable plate (3) are respectively installed at two sides of the top of the manual pulley (4); an upper transverse connecting rod (1) passes between the fixed plate and the movable plate (3); two ends of the upper transverse connecting rod (1) are respectively connected with the fixed plate and the movable plate (3); channel steel (5) is installed at the bottom of the manual pulley (4); and at least two fastening bolts (6) are installed on the channel steel (5). After adopting the upturned pulley for replacing the tension insulator disclosed by the utility model, application proves that the working platform can be effectively increased, physical consumption of operators is greatly reduced, the working difficulty is reduced, and the problem of being time-saving and labour-saving to replace the whole string of porcelain bottles is solved.
Description
Technical field
The utility model relates to a kind of strain insulator replacing and uses towards sky coaster.
Background technology
In the 330kV circuit putting into operation in the Northwest, strain insulator-string all adopts porcelain insulator, and tension-resistant porcelain bottle all adopts two string porcelain vases, and porcelain vase design pulling force is 21kN, weight 8～10kg, whole string porcelain vase 176～220kg.Change bunch of insulator, due to whole string porcelain vase and replacing instrument overweight, when erecting tools and porcelain vase string, because the suspension centre of endless rope is low, cause staff very difficult at high-altitude application, virtually increased operating personnel's danger.
Charged for replacement 330kV strain insulator-chain electrical insulator is a very important project in line maintenance work at present, but in more changing jobs, because 330kV circuit porcelain vase design pulling force is 21kN, weight 8～10kg, whole string porcelain vase 176～220kg, changes jig heavy, and installation is wasted time and energy, staff is very difficult at high-altitude application, and the security risk that larger physical consumption brings to operating personnel is also very large.
Utility model content
The purpose of this utility model is to provide a kind of strain insulator replacing and uses towards sky coaster, can improve working face platform, thereby reduce greatly operating personnel's physical consumption after use.
A kind of strain insulator is changed and is used towards sky coaster, its special feature is: comprise manual coaster, in these both sides, manual coaster top, be separately installed with fixed head and portable plate, between this fixed head and portable plate, pass and have top tranverse connecting rod, and the two ends of this top tranverse connecting rod are connected with portable plate with fixed head respectively; At this manual arse, channel-section steel is installed, at least 2 fastening bolts are installed on this channel-section steel.
Wherein fixed head and portable plate are arc.
Wherein the bottom of portable plate is hinged with manual coaster top, and adopts and removably connect between this portable plate and top tranverse connecting rod.
Wherein removably connect bayonet socket is specifically installed on portable plate, and the revolving type locking with this bayonet fittings is installed on the tranverse connecting rod of top, thereby can make fixing between portable plate and top tranverse connecting rod or unclamp.
Through probationary certificate, adopt strain insulator of the present utility model to change and use after sky coaster, can effectively improve working face platform, reduce greatly operating personnel's physical consumption, reduce work difficulty, solve the problem that whole string porcelain vase is wasted time and energy of changing.It is breach that the utility model be take the hanging point of rising endless rope, by yoke plate, supports towards sky coaster, and the high scope of operation of frame, reaches and alleviate work load, shortens the activity duration, reduces the beneficial effect of job safety risk.During use, by being connected to the coaster on strain insulator-string side of wire was yoke plate, the high endless rope of frame, improves the suspension centre of topmost endless rope, can obviously alleviate live line working personnel's operation intensity, reduces work difficulty, increases operating efficiency, improves operational security.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, 2, the utility model is that a kind of strain insulator replacing is used towards sky coaster, comprises manual coaster 4, and manually coaster 4 is comprised of pulley and a shell substantially.In these manual coaster 4 both sides, top, be separately installed with fixed head and portable plate 3, between this fixed head and portable plate 3, pass and have top tranverse connecting rod 1, and the two ends of this top tranverse connecting rod 1 be connected with portable plate 3 with fixed head respectively.In these manual coaster 4 bottoms, channel-section steel 5 is installed, 2 fastening bolts 6 are installed on this channel-section steel 5.
Wherein fixed head and portable plate 3 are arc, and the bottom of portable plate 3, with manually coaster 4 tops are hinged, removably connect and adopt between this portable plate 3 and top tranverse connecting rod 1, thereby facilitates endless rope to pass.On portable plate 3, bayonet socket is installed in addition, and the revolving type locking 2 with this bayonet fittings is installed on top tranverse connecting rod 1, thereby can make fixing between portable plate 3 and top tranverse connecting rod 1 or unclamp.
Using method of the present utility model is:
During use, by channel-section steel 5 and fastening bolt 6, the utility model is connected on strain insulator-string side of wire was yoke plate to the high endless rope of frame, the suspension centre of raising topmost endless rope, thereby alleviate live line working personnel's operation intensity, reduce work difficulty, increase operating efficiency, improve operational security.
