Abstract
The present invention relates to a kind of big span tension stringing construction method, big span tension stringing support frame is installed on two ground for needing to draw between the steel tower of stringing, the big span tension stringing support frame jack-up draught line.The big span tension stringing support frame includes pole support, upper support, towards top sheave group and gag lever post, pole support upper end both lateral sides are symmetrically fixed with support, four groups are uniformly provided with the top lateral separation of upper support towards top sheave group, every group is fixed with a gag lever post towards the upper support top in the middle part of top sheave group both lateral sides.The present invention installs support frame in big span, shortens distance in independent span, and then shorten the distraction force of stretching machine, it is to avoid occur bracket phenomenon, although the structure of this support frame is simple, efficiently solves the technical barrier for being difficult to overcome for a long time.
Description
Technical field
The present invention relates to for big span Poling Construction in electric transmission line erection, especially a kind of big span tension stringing is applied
Work method and support frame.
Background technology
In electric transmission line erection in big span Poling Construction, distraction force, which crosses conference, causes constructional difficulties, according to long-term
The statistics of construction experience and live distraction force construction note, analysis finds that it is not strain section really to influence distraction force excessive
Apart from long, but a certain independent span is excessive in strain section causes distraction force to increase.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind is simple in construction, reduction is taken up an area, be easy to apply
The big span construction method of work, safe and reliable tension stringing and support frame.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of big span tension stringing construction method, it is characterised in that：Between two steel towers for needing traction stringing
Big span tension stringing support frame is installed, the big span tension stringing support frame jack-up draught line on ground.
Moreover, the big span tension stringing support frame includes pole support, upper support, towards top sheave group and spacing
Bar, pole support upper end both lateral sides are symmetrically fixed with support, and four groups are uniformly provided with the top lateral separation of upper support
Towards top sheave group, every group is fixed with a gag lever post towards the upper support top in the middle part of top sheave group both lateral sides.
Moreover, being made up of towards top sheave assembly pulley a central pulley and two edge pulleys, central pulley and side
Edge pulley coaxle is to central pulley is arranged on upper support top middle portion, and it is forward and backward that two edge pulleys are symmetrically mounted on central pulley
The upper support top of both sides, central pulley than on edge pulley along high.
Moreover, being fixed with raker beam, upper support and raker beam between the side wall of cantilever end and the pole support of upper support
Between tilt be fixed with a plurality of buttress brace.
Moreover, the transverse ends in upper support are symmetrically fixed with hangers.
Advantages and positive effects of the present invention are：
The present invention installs support frame in big span, shortens distance in independent span, and then the distraction force of shortening stretching machine,
Avoid occurring bracket phenomenon, although the structure of this support frame is simple, efficiently solve the technology for being difficult to overcome for a long time difficult
Topic.

Fig. 1 is form of construction work schematic diagram of the invention；
Fig. 2 is the structural front view of big span tension stringing support frame；
Fig. 3 is Fig. 2 right view.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of big span tension stringing construction method, referring to shown in accompanying drawing 1, between two steel towers for needing traction stringing
Ground on big span tension stringing support frame is installed, the big span tension stringing support frame jack-up draught line, thus shorten solely
Distance in vertical span, reduces distraction force.
The concrete structure of the big span tension stringing support frame referring to shown in accompanying drawing 2 to accompanying drawing 3, including pole support 7,
Upper support 4, towards top sheave group and gag lever post 3, pole support upper end both lateral sides are symmetrically fixed with support, in upper support
Top lateral separation is uniformly provided with four groups towards top sheave group, and every group equal towards the upper support top in the middle part of top sheave group both lateral sides
A gag lever post is fixed with, limitation wire passes through towards correspondence position in top sheave group；
It is made up of towards top sheave assembly pulley a central pulley 1 and two edge pulleys 2, central pulley and edge are slided
Wheel is coaxial, is arranged sideways in triangle disposition, and central pulley is arranged on upper support top middle portion, and two edge pulleys are symmetrically installed
On the upper support top of central pulley front and rear sides, central pulley than on edge pulley along high, it is ensured that wire slides flexible.
In order to ensure structural strength, raker beam 6 is fixed between the side wall of cantilever end and the pole support of upper support, on
Tilted between support and raker beam and be fixed with a plurality of buttress brace 8, enhancing structure intensity.
For the ease of installation and movable supporting frame, hangers 5 is symmetrically fixed with the transverse ends of upper support, is easy to connection
Rope.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modifications all be it is possible,
Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
