Abstract
The utility model discloses a lifting type crawling-ladder structure of a single-pipe tower. The lifting type crawling-ladder structure comprises a ladder rod fixed on the outer wall face of a tower rod and pedals fixed on the two sides of the ladder rod in a staggered mode in the vertical direction, the outer ends of the pedals tilt upwards in a inclined mode, and the inner ends of the pedals penetrate through the ladder rod and are fixed with the ladder rod in a clamping or welding mode. The ladder rod is a hollow pipe, and the ladder rod is fixedly connected to the tower rod through a plurality of screws. The crawling ladder can be conveniently installed on the tower rod so that an operator can conveniently install and maintain a signal receiving and transmitting device arranged on the upper portion of the tower rod, and the crawling ladder is simple in structure, simplified in component, quick and convenient to install, and low in cost.
Description
Technical field
The utility model belongs to the single-pipe tower technical field of structures, is specifically related to a kind of cat ladder structure that is arranged on head tower bar position under the ascending/decending single-pipe tower.
Background technology
At present in shop, communication, broadcasting, TV signal lamp field extensively adopts communication tower to carry out transmission of wireless signals, communication tower is generally that the tower body of more piece is installed one by one, at tower top, signal receiving/transmission device is installed again finally, installation process need to be used large-scale crane, many main equipments such as aerial work platform are auxiliary, the construction trouble, engineering quantity is large, and there is certain danger in operating personnel.
Summary of the invention
The purpose of this utility model is:, for the deficiency that prior art exists, provide a kind of cat ladder structure of ascending/decending single-pipe tower.
For realizing the purpose of the utility model, be achieved by the following technical solutions: a kind of cat ladder structure of ascending/decending single-pipe tower, include a terraced bar that is fixed on tower bar outside wall surface, and the staggered pedal that is fixed on terraced bar both sides vertically, the perk obliquely upward of pedal outer end, pedal the inner are passed terraced bar and with terraced bar clamping or be welded and fixed.
As preferred version: described terraced bar is hollow tube, and terraced bar is fixedly connected on the tower bar by a plurality of screws.
As preferred version: described terraced rod end surface is the rectangle of long 50mm, wide 30mm.
As preferred version: the length a of described pedal is 14-16cm, and the distance b between adjacent two pedals is 30-40cm.
Compared with prior art, the beneficial effects of the utility model are: this cat ladder can be arranged on easily on the tower bar with the handled easily personnel signal receiving/transmission device on tower bar top is carried out installation and repairing.This cat ladder is simple in structure, and parts are simplified, and is quick and easy for installation, and cost is low.

The specific embodiment
Below with reference to the accompanying drawings the specific embodiment of the present utility model is made a detailed explanation.
According to illustrated in figures 1 and 2, the cat ladder structure of the described a kind of ascending/decending single-pipe tower of the present embodiment, include a terraced bar 61 that is fixed on tower bar outside wall surface, and the staggered pedal 52 that is fixed on terraced bar 61 both sides vertically, pedal outer end 621 perk obliquely upward, pedal the inner 622 are passed terraced bar 61 and with terraced bar 61 clampings or be welded and fixed.
Described terraced bar 61 is hollow tube, and terraced bar 61 is fixedly connected on the tower bar by a plurality of screws 63.
Described terraced bar 61 end faces are the rectangle of long 50mm, wide 30mm.
The length a of described pedal 62 is 15cm, and the distance b between adjacent two pedals 62 is 35cm.
Described tower bar includes the body of rod of five joint sockets, and this cat ladder 6 is arranged on lower tower bar 4 sidewalls of below, and the sky of monochromatic light tower 9 is arranged on the upper tower bar 8 of the top.Described lower tower bar 4 is fixedly connected on a steel frame 2, and lower tower bar 4 belows are provided with steel column 3 with its support.
When single-pipe tower is installed, steel column 3 temporarily need to be replaced with jack, utilize jack that each joint tower bar is upwards pushed up, described upper tower bar 8 is ejected at first so that described day 9 and other accessory are installed, this moment, the constructor can use described cat ladder 6 climbings to construct to the upper end position of lower tower bar 4, and is very easy to use.
This cat ladder can be arranged on easily on the tower bar with the handled easily personnel signal receiving/transmission device on tower bar top is carried out installation and repairing.This cat ladder is simple in structure, and parts are simplified, and is quick and easy for installation, and cost is low.
