Abstract
The utility model relates to a monotube tower with a telescopic step nail and a concealed outside flange, which is used for a tower structure, such as a post telephone and telegraph telecommunication monotube tower, an electricity transmission monotube tower, a dual-tube tower, etc. Primarily, a telescopic outer step nail ladder is used as a ladder for climbing and getting down, in normal time, step nails shrink in a barrel body of a tower body and can only extend out when an installing and maintaining worker is climbing or getting down. A machine body which is the tower with step nails concealed in the ladder in normal time is as beautiful as an inner ladder monotube tower and is used as conveniently as an outer ladder. A concealed outside flange is installed and maintained safely with the operation as simple and convenient as an outside flange. The outer diameter of the flange is smaller than the barrel body of the monotube tower with the thickness of about one anchor ear, so after maintenance is finished, the flange can be embraced by an ornamental anchor ear and can not be seen from outside so as to keep the beautiful appearance of the tower body in an inner flange structure and simultaneously to keep the simple and convenient installation of an outer flange. A feed line frame is used for a feed line, a vertical bracket is made of steel cable which is injected into the tower body after the feed line is installed on the ground, then the upper end of the feed line is fixedly connected to the tower body through an ear ring and the lower end is strained tightly by a flower basket screw bolt after is fixedly connected to the ground through another ear ring.
Description
Technical field
The utility model relates to the post and telecommunications single-pipe tower, refers to that especially a kind of flexible step follows closely the single-pipe tower of hidden outward flange.
Background technology
Existing single-pipe tower adopts outward flange, outer cat ladder, adorns feeder line and inner flange, interior cat ladder and two kinds of forms of interior dress feeder line outward; Its main pluses and minuses are:
Outward flange, outer cat ladder and adorn feeder line outward, its advantage are easy for installation simple, shortcoming be exposed outside, influence look of the city.
Inner flange, interior cat ladder and interior dress feeder line, its advantage is aesthetic in appearance, and appearance be can't see flange, cat ladder and feeder shelf, and is very succinct, but owing to will carry out in the body of the tower cylindrical shell up and down the time in that inner flange and personnel are installed, requiring just can provide certain space than major diameter.But reach from the angle of good looking appearance and saving steel from structural strength and rigidity requirement, the single-pipe tower height is when being lower than below 40 meters, the minimum diameter at position is less than φ 800mm about its personnel, and the people can't pass through in cylindrical shell, and interior cat ladder, inner flange just can't be realized.
Summary of the invention
The purpose of this utility model is: provide a kind of tower height to be lower than 40 meters, under the situation that interior cat ladder, inner flange and interior installation feeder line can't be implemented, the advantage of cat ladder, inner flange and interior installation feeder line in keeping again, promptly appearance flexible step of can't see cat ladder, flange and feeder shelf is followed closely hidden outward flange single-pipe tower.
For reaching above-mentioned purpose, the utility model is by some pitch cone shape single tube tower bodies, and flange is formed by connecting with high-strength bolt, is characterized in:
1, adopt telescopic outer step nail as personnel's cat ladder up and down, nail contracts in the tower body stack shell step at ordinary times, installs and maintainer up and down the time, and the step nail is stretched (single manually flexible and whole Volleyball Association is moving stretch).Personnel can nail on down along the step.This mechanism can't see at ordinary times as step of cat ladder nail, and when needing, the step nail is extended to be used as outer cat ladder use, really accomplished the same attractive in appearance with interior cat ladder single-pipe tower, the same with outer cat ladder convenient and simple during use.
2, concealed type outward flange, its installation and when maintenance and outward flange are easy and simple to handle equally, safe and reliable, and Maintenance and Repair are convenient easy to operate.Because flange outer diameter is than the thickness of the also little anchor ear of single-pipe tower cylindrical shell, after installation and maintenance are finished, embrace the ornamental anchor ear of a last circle, appearance be can't see flange, only stay two seams also littler (2-3mm) than weld seam, can't see flange at all, kept the tower body of inner flange structure aesthetic in appearance, kept the installation of outward flange simple and convenient again.
3, feeder line adopt flexible feeder shelf by wire rope as vertical support frame, after floor mounted, pour in the tower body, the upper end is fixed by earrings and tower body, lower end earrings and ground are fixed, be strained and fixed with the flower basket bolt location, it is tight with vertical rope cramp that the angle steel of feeder line is used steel wire rope clip, and tower body top and bottom feeder line should be opened fairlead on cylindrical shell, perforate position steel plate reinforcement.
4, establish the flexible work wicket that goes on foot nail and locate flexible feeder shelf of an operations linkage in single-pipe tower cylindrical shell bottom, be convenient to operation.
The utility model has the advantages that: adopt telescopic outer step nail to make cat ladder up and down: concealed type outward flange outer ring is with an ornamental anchor ear, and appearance be can't see flange; Flexible feeder shelf is placed in the tower body, and whole tower body has kept in interior cat ladder, the inner flange feeder line structure equally attractive in appearance, but fitting operation and outer cat ladder, outward flange are the same convenient.The advantage that has kept two kinds of single-pipe towers.
