Description
Technical field
The utility model relates to a kind of work high above the ground pulley, particularly a kind of transmission line slip-off preventing overhead wire pulley.
Background technology
In transmission line, the operation of overhead transmission line needs a kind of cabling pulley usually, this cabling pulley includes pulley component and operation connector, wherein pulley component is arranged in an open frame, described operation connector is for connecting the instrument, cable etc. during operation, be generally a kind of annulus, for colligation or mounting article.During use, by the opening part of framework, cabling pulley is hung and rides on overhead wire, the operation conveying now can slided on overhead wire on overhead wire by pulley component.
But the weak point of above-mentioned cabling pulley is, pulley component is arranged in open frame, that is after overhead wire is inserted in pulley component, still be in open state, when now cabling pulley moves on overhead wire, the vibration of overhead wire can be caused, cabling pulley is caused to bounce on line further, cabling pulley is deviate from from the opening part of framework, and finally cause cabling pulley to come off from overhead wire, this will cause work accident, therefore Job Operations process is unstable, and security reliability is low.In prior art, also have and adopt closed pulley structure, as Chinese patent 201420099428.1, but, this enclosed construction must just can be opened in manual operation, easily hangs up line, is but difficult to separate, cannot adapt to the demand of the remote work high above the ground of overhead wire, operation inconvenience, fail safe is low.
Utility model content
The purpose of this utility model be to provide according to the deficiencies in the prior art part a kind of easy to operate, fail safe is high, the transmission line slip-off preventing overhead wire pulley of good reliability.
The purpose of this utility model is realized by following approach:
Transmission line slip-off preventing overhead wire pulley, its structural feature is, include overhead wire wheel carrier and rope wheel carrier, overhead wire wheel carrier includes open frame, top sheave and closure member, and open frame includes inverted U framework and connecting frame, and top sheave to be arranged in inverted U framework in space, wherein inverted U framework side plate and connecting frame Construction integration, another side plate is opening side plate, and the curved structure that turns up of its free end, forms an opening with a side of connecting frame, closure member includes closed pin member, caging bolt, Compress Spring and operation draw ring, closed pin member is elongated structure, its major axis is parallel with overhead wire wheel carrier longitudinal central axis, outside the opening side plate being positioned at inverted U framework, close in the middle part of pin member and Y is provided with a guide-track groove, one of them axle end evagination of top sheave is outside opening side plate, caging bolt is also installed on opening side plate simultaneously, simultaneously the axle end of top sheave and caging bolt are arranged in the guide-track groove of closed pin member, one end of Compress Spring is connected with the axle end of top sheave, the other end is then fixedly connected with the rearward end of closed pin member, operation draw ring is positioned at the rearward end of closed pin member, with closed pin member Construction integration, under normal conditions, Compress Spring is Pre strained state, closed pin member now just in time encloses the whole opening of open frame, rope wheel carrier includes outside framework and lower sheave, and lower sheave is arranged on the inner chamber of outside framework, and connecting frame is fixedly connected with by securing member with the outside framework of rope wheel carrier.
Described guide-track groove provides the moving track of closed pin member, and the axle end of top sheave and caging bolt form two one lines, spacing and fixing for carrying out guide-track groove, Compress Spring then provides initial tension of spring, under normal conditions, closed pin member is made to be in the state of closing openings all the time.Operation draw ring is used for connection to be needed to carry out remote operated insulating bar.
The utility model is provided with one can carry out remote operated slip-off preventing overhead wire pulley, first overhead wire wheel carrier and rope wheel carrier has been distinguished, the two is placed in different frame spaces, can avoids like this having influence on rope wheel carrier when those operate to overhead wire wheel carrier; Secondly, provide a kind of can the overhead wire wheel carrier of folding, closed pin member is set, be closed state under making normality, during use, only need pull operation draw ring, closed pin member pulled back, now Compress Spring is stretched, and closed pin member withdraws the opening part of open frame, expose opening, pulley is linked into overhead wire by this opening, removes the pulling force of operation draw ring, under the reset response of Compress Spring, closed pin member playbacks again, and the whole opening of closing openings framework; In this process, only need to adopt insulating bar to hook operation draw ring, mention whole pulley, just under the gravity reaction of pulley, closed pin member can have been lifted, exposed opening, then just pulley can be linked into overhead wire, or withdraw overhead wire.Therefore, slip-off preventing overhead wire pulley described in the utility model, due to the closed state that is in the normal state in use procedure, therefore there will not be the situation about coming off of bouncing, stable operation, reliable; In addition, provide and can carry out remote operated technical characterstic, fully adapt to the demand of the remote work high above the ground of overhead wire, easy to operate, fail safe is high, good reliability.
The utility model can be specially further:
Described connecting frame is a kind of right-angled triangle frame structure, and the hypotenuse of triangular framing and the arc of opening side plate turn up formation of structure open channel; The bottom of triangular framing is then fixedly connected with rope wheel carrier by securing member.
This open channel can contribute to that whole pulley is orderly to be smoothly linked into or to withdraw overhead wire.And triangle is a kind of stable geometric figure, this structure can increase stability and the rigidity of whole pulley structure, increases fail safe and the reliability of slip-off preventing pulley further.
In sum, the utility model provides a kind of transmission line slip-off preventing overhead wire pulley, which provide a kind of can the overhead wire wheel carrier of folding, closed pin member is set, be closed state under making normality, only need to adopt insulating bar to hook operation draw ring, mention whole pulley, just can under the gravity reaction of pulley, lift closed pin member, expose opening, facilitate pulley to be linked into overhead wire, or withdraw overhead wire.Therefore there will not be the situation about coming off of bouncing, stable operation, reliable; In addition, provide and can carry out remote operated technical characterstic, fully adapt to the demand of the remote work high above the ground of overhead wire, easy to operate, fail safe is high, good reliability.
