Abstract
A double wheel upturned pulley comprises a pulley frame formed by connecting two rectangular steel plates through screws and keyways, shaft stools are fixed on the two ends of the pulley frame, a fixing shaft is arranged on each shaft stool, a bearing is arranged on the fixing shaft, a pulley is arranged on the bearing, the two sides of the shaft are fixed with the shaft stool with screws, and the sides and the upper part of the shaft stool are respectively provided with a ladder-shaped conducting wire anti-shedding rack with a wide upper part and a narrow lower part. The pulley can be stretched to any needed suitable lengths, and can bear large rigid stress when a wire is tightened; when a conducting wire or a steel wire rope passes through the pulley, the wire-tightening position is close to the real position and the error is small as the upturned pulley design is adopted; and working personnel can be prevented from being damaged by the conducting wire shedding, and the work can be completed rapidly and effectively. Moreover, the shortages of low wire-hanging point, large abrasion and restricted bearing direction can be avoided; the advantages of light molding, simple structure and convenient carrying can be realized; and the pulley can be widely used in power substation flexible bus bar wire-tightening work.
Description
Technical field
The utility model relates to a kind of built on stilts bus prestretch block, especially is applicable to the coaster of built on stilts flexible cord stringing.
Background technology
At present, built on stilts flexible cord stringing mode commonly used has two kinds, a kind ofly is to use conventional iron block to hang on below the hanging wire point, utilizes steel wire rope to affect the stringing mode of aluminum seton device.This kind mode is because the actual hanging wire point of stringing point distance is lower, and the result of measurement can not truly reflect the sag of lead, is easy to generate loose tension phenomenon.Especially hydraulic joint can not be changed after the crimping, and the error of measurement can directly cause the waste of lead.The second way is to use common black rubber board, places on the bus crossbeam, utilizes the stringing mode of force of sliding friction.There is following shortcoming in this kind mode: 1, owing to be to utilize sliding friction, the angle of traction will be more than 60 °, otherwise easy abrasion, rigid curved lead; 2, the rubber board both sides do not stop, the side direction traction can hurt the operating personnel, so the traction side can only be selected in the dead astern of stringing point; 3, only be applicable to the less bus stringing in little span or line footpath.Addressing these problems becomes urgent need.
The content of utility model
Overcome the deficiency of prior art, provide a kind of two-wheel towards the sky coaster, this coaster not only can successfully solve many deficiencies of above-mentioned stringing mode, and light and handy, be easy to carry, effectively increase work efficiency.Two-wheel towards the sky coaster it comprise the apparatus for suspension that two block length square plates are formed by connecting through screw and keyway; Be fixed with at the two ends of apparatus for suspension fixed axis is housed on shaft stool, the shaft stool, install pulley being equipped with on the fixed axis on bearing, the bearing; The axle both sides fix with screw and shaft stool, the shaft stool both sides and above install a terraced font lead anticreep frame wide at the top and narrow at the bottom respectively.
Narrow place, said terraced font lead anticreep frame lower end offers U type groove, be affixed on the shaft stool outside, by bearing screw and under fixed leg fix;
Said two block length square plates respectively 90 ° of one of which end downwarpings, curve inwardly 45 ° again, wherein offer keyway in the middle of the block plate, are provided with two screws in the middle of another block plate.
Said shaft stool both sides are provided with the reinforcing metalwork.
The utility model adopts the keyway in the middle of the two block length square plates to be connected with the mode of screw, through the adjustment of screw diverse location in keyway, can adjust the distance between two pulleys, can coaster be stretched to the appropriate length of any needs; Owing to be provided with rigidity stress bigger when reinforcing metalwork so can bear stringing in the shaft stool both sides; When lead or steel wire penetrating coaster, can make the stringing position very near physical location towards the design of top sheave, error is very little.Pulley adopts rolling friction simultaneously, has reduced the lead wearing and tearing; Owing to above pulley, be equiped with terraced font lead anticreep frame; Therefore can make stringing no longer be bound to the dead astern, within about center line 30 °, all can select lead; Guarantee the injury that the staff does not receive lead to deviate to produce simultaneously, thereby finish the work fast and efficiently.When the soft bus stringing of electric substation, can avoid effectively that hanging wire point is low, wearing and tearing are big, receive the limited shortcoming of force direction, another advantage of the utility model is that moulding is light and handy, and is simple in structure.

Embodiment
Two-wheel towards the sky coaster it comprise the apparatus for suspension that two block length square plates 1 are formed by connecting through screw 4 and keyway 10; Be fixed with at the two ends of apparatus for suspension fixed axis 5 is housed on shaft stool 3, the shaft stool, installing pulley 2 on bearing 8, the bearing is being housed on the fixed axis; The axle both sides fix with screw and shaft stool, the shaft stool both sides and above install a terraced font lead anticreep frame 6 wide at the top and narrow at the bottom respectively.Narrow place, said terraced font lead anticreep frame lower end offers U type groove, be affixed on the shaft stool outside, by bearing screw and under fixed leg 9 fixing, the effect of fixed leg is to prevent that the anticreep frame from tilting along the lead lead; Two block length square plates 1; 90 ° of one of which end downwarpings, curve inwardly 45 ° more respectively, wherein offer keyway in the middle of the block plate; Be provided with two screws in the middle of another piece iron plate; Screw 4 is used for the steel plate connection among being through at keyway, through the adjustment of screw diverse location in keyway, can adjust the distance between two pulleys; The shaft stool both sides are provided with and reinforce metalwork 7, are used to improve the iron plate mechanical strength.Coaster is fixed on the lead suspension base.
