Abstract
The utility model discloses an outer climbing mono-pipe tower which comprises a tower body (1) and a climbing stair (2) fixed on the tower body (1), wherein the climbing stair (2) is composed of a fixed beam channel (9), a movable connecting rod (8), footstep stems (10), upper chock blocks (12) and lower chock blocks (11). The fixed beam channel (9) of which the notch is inward is fixed on the tower body (1), the movable connecting rod (8) is positioned in the fixed beam channel (9), the footstep stems (10) are homogeneously hinged on both sides of the movable connecting rod (8), the upper chock blocks (12) are arranged on the fixed beam channel (9) above the footstep stems (10), and the lower chock blocks (11) are arranged on the fixed beam channel (9) below the footstep stems (10). When the utility model with the structures operates, the movable connecting rod (8) is jacked up, and then the footstep stems (10) can extend out like umbrella sticks, so that the climbing work can be done. Under a non-operating state, the footstep stems (10) can automatically retract and hide at the rear of the fixed beam channel (9). The utility model has the advantages of simple structure, convenient manipulation, material saving, low cost, safe reliability, etc.
Description
One, technical field
The invention relates to a kind of communication launching tower, particularly a kind of external climbing single-pipe tower.
Two, background technology
In recent years, along with the development that mechanics of communication is advanced by leaps and bounds, communication had also obtained use more and more widely with launching tower; Communication is the earliest adopted the trussed construction form with launching tower, the tower structure complexity of this mode, member are many, the making amount greatly, the construction and installation difficulty is big, long in time limit, floor space is big, now do not adopt basically.What use was more at present is the inner climbing type single-pipe tower, the tower of this mode is climbed cat ladder and is installed in tower body inside, because the staff climbs in inside, no matter body of the tower height, its tower body bore just requires bigger, will certainly cause material to increase, this not only gives transportation and installs increases difficulty, and causes cost of production high.
Three, summary of the invention
In order to overcome the defective that existing communication exists with launching tower, the invention provides the external climbing single-pipe tower that a kind of body bore is little, cost is low, safe and reliable and elegant in appearance.It is to comprise tower body and be fixed on cat ladder on the tower body that the invention solves technical scheme that its technical problem adopts, described cat ladder is by fixedly channel-section steel, movable rod, step fourth, last block and following block are formed, the inside fixedly channel-section steel of notch is fixed on the tower body, movable rod is arranged on fixedly in the channel-section steel, described step fourth evenly is hinged on the movable rod both sides, last block is arranged on the fixedly channel-section steel of step fourth top, and following block is arranged on the fixedly channel-section steel of step fourth below.
Install and inspection for the ease of the staff, described tower body is connected to form by some joint back cut diameters body little, that lower port diameter is big, and the connection end face of upper and lower body is provided with the inner flange that interfixes, and is provided with upper and lower hand hole on upper and lower body successively.On the upper and lower hand hole of upper and lower body, be fixed with the hand hole stiffening plate.On the inner flange of upper and lower body, be fixed with stiffener.
After adopting said structure, when work with small-sized jack from following jack-up movable rod, the step fourth is stretched out as umbrella frame, the staff can climb operation, when off working state, the step fourth is packed up and hidden in fixing channel-section steel back under the effect of movable rod deadweight automatically, can prevent that the inoperative personnel from climbing, and can effectively avoid the generation of contingency; Adopt inner flange fixedly connected between the body, make tower body one integrated mass, elegant in appearance in appearance; Adopt the outer cat ladder structure of concealed type, its tower diameter is 2/3rds of an inner climbing type single-pipe tower when contour; Have characteristics such as simple in structure, easy to operate, that material is economized, cost is low, safe and reliable.

Five, the specific embodiment
Fig. 1 is the specific embodiments of the invention external climbing single-pipe tower to shown in Figure 6.It comprises tower body 1 and the cat ladder 2 that is fixed on the tower body 1, described cat ladder 2 is by fixedly channel-section steel 9, movable rod 8, step fourth 10, last block 12 and following block 11 are formed, the inside fixedly channel-section steel 8 of notch is fixed on the tower body 1, movable rod 8 is arranged on fixedly in the channel-section steel 9, described step fourth 10 evenly is hinged on movable rod 8 both sides, last block 12 is arranged on the fixedly channel-section steel 9 of step fourth 10 tops, and following block 11 is arranged on the fixedly channel-section steel 9 of step fourth 10 belows.Install and inspection for the ease of the staff, described tower body 1 is composed of a fixed connection by some joint back cut diameters body little, that lower port diameter is big, the connection end face of upper and lower body is provided with the inner flange 5 that interfixes, and is provided with upper and lower hand hole 3,4 on upper and lower body successively.In order to improve the mechanical strength of upper and lower hand hole 3,4, on the upper and lower hand hole 3,4 of upper and lower body, be fixed with hand hole stiffening plate 7.In order to guarantee that inner flange 5 and upper and lower body are connected firmly, and are fixed with stiffener 6 on the inner flange 5 of upper and lower body.
The invention in when work, with the bottom jack-up movable rod 8 of small-sized jack from movable rod 8, step fourth 10 is stretched out as umbrella frame, step fourth 10 is stretched out a fixedly side pressure of channel-section steel 9 and is being descended on the block 11, opposite side withstands on block 12, as shown in Figure 4, the staff can climb operation.When off working state, step fourth 10 is packed up automatically and hiddenly as shown in Figure 6, can be prevented inoperative personnel climbing in fixing channel-section steel 9 back under the effect of movable rod 8 deadweight, can effectively avoid the generation of contingency.
