Abstract
The utility model relates to a ladder, especially relates to a ladder for aloft work, comprising a tow hook at the top composed of a hook and an iron chain between one end of the hook and the hook main body; a multi-layer ladder bed vertically connected in the middle part, each layer of the ladder bed enclosing a polygon and the ladder bed comprising a transverse rod and a vertical rod, a connection device fixed at the bottom of each vertical rod and for connecting upper, lower vertical rods, wherein each connection device is connected by a connection rod at a same height; a ladder foot at the bottom and comprising a flat plate welded below the vertical rod on the lowest layer and an universal wheel with locking function below the flat plate. The multi-purpose ladder is used for mounting and repairing the pipeline, steel structure, device, electric device and etc, reducing the construction preparation time and saving the work material and is safe.
Description
Technical field
The utility model relates to ladder, relates in particular to the ladder that a kind of aerial work is used.
Background technology
In pipeline, steel work, equipment, electric installation, maintenance construction, construction operation traditional method in high-altitude is to set up scaffold, use bamboo ladder, double ladder, set up scaffold waste material when useless, use the height of bamboo ladder, double ladder construction limited and can only a people construct in the above.
Summary of the invention
The utility model is intended to address the above problem, and a kind of work high above the ground multipurpose ladder is provided.The utility model is used for installing, maintenance pipeline, steel work, equipment, electric etc., reduces the preparation of construction time, saves labor and materials, safety.
The utility model is achieved in that a kind of work high above the ground multipurpose ladder, and it comprises:
The hook at top, it comprises hook and is connected iron chains between hook one end and the hook body;
The middle part is provided with the multilayer ladder that connects up and down, and every layer of ladder surrounds into a polygon, and described ladder comprises cross bar and montant, is fixed with in the bottom of each montant to connect the linkage of montant up and down, and each linkage connects with connecting rod at sustained height;
The foot of ladder of bottom, it comprises the universal wheel that is welded on the dull and stereotyped of undermost montant below and is connected the tight function with lock under this flat board.
Described a kind of work high above the ground multipurpose ladder, described linkage are the pipe that is located at montant bottom, and its epimere suit also is welded on the bottom of upper strata montant, and its hypomere is enclosed within the upper end of lower floor's montant, and is connected by bolt radially.
Described a kind of work high above the ground multipurpose ladder, described ladder is centered around together, forms triangle, rectangle, square, pentagon or hexagon.
The utility model should be made up of ladder top hooking device, ladder, foot of ladder device, coupling assembling.This ladder construction cost is low, reusable, reduces the cost and the labour intensity of construction greatly, and simple to operate, assembling rapidly, accurately, and comprehensive benefit is very remarkable.The utility model is fit to be applied to highly be no more than 30 meters occasion.
Description of drawings
Below, in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 a is the schematic diagram of a top hook among the embodiment;
Fig. 2 b is the schematic diagram of the top hook among described another embodiment;

The specific embodiment
As shown in Figures 1 to 4, a kind of work high above the ground multipurpose ladder, it comprises:
The hook 1 at top, it comprises hook and is connected iron chains 11 between hook one end and the hook body; This hook can for circular arc or right angle tetragonal (as Fig. 2 a or Fig. 2 b)
The middle part is provided with the multilayer ladder 2 that connects up and down, every layer of ladder 2 surrounds into a polygon, described ladder 2 comprises cross bar 21 and montant 22, is fixed with in the bottom of each montant 22 to connect the linkage 3 of montant up and down, and each linkage 3 connects with connecting rod at sustained height; Ladder can center on triangle, rectangle, square, pentagon or hexagon.What show among Fig. 1 a is square.
The foot of ladder 4 (referring to Fig. 4) of bottom, it comprises the universal wheel 42 that is welded on the dull and stereotyped of undermost montant below and is connected the tight function with lock under this flat board 41.
Described linkage 3 is for being located at the pipe of montant 22 bottoms, and its epimere suit also is welded on the bottom of upper strata montant, and its hypomere is enclosed within the upper end of lower floor's montant 22, and is connected by bolt radially.
When adopting 2 above overhead pipelines of DN150 to weld counterparts in the construction, 2 hooking devices 1 in top and ladder 2 are assembled according to construction height, be lifted on the pipeline with crane or rope on ground.For not run-off the straight needs with iron chains ladder to be fixed on the pipeline.
When steel work, equipment, electric installation, maintenance construction, on ground the hooking device 1 in top and ladder 2 are assembled according to construction height, be hung on steel work or the pipeline with crane or rope, at this moment reliable fulcrum must be arranged at the ladder bottom.
At the construction scene that the plane is relatively good and hardened in ground, on ground foot of ladder device 3 and ladder 2 are assembled, increase ladder 2 according to construction height, with universal wheel 42 lockings, prevent sliding stop during use; The ramp period of the day from 11 p.m. to 1 a.m is opened universal wheel 42 locking devices.
