When work, by fixing piece one of in fixing piece, such as the first fixing piece 30 carries out attached wall with building structure and consolidates
It is fixed, then start the lifting gear 20, under the action of the driving motor 21, the chain 22, transmission rope 60 are passed
It is dynamic, and so that the single unit system in addition to the first fixing piece 30 is lifted, meanwhile, another fixing piece in fixing piece, such as
Second fixing piece 50 also synchronization lifting.When single unit system is lifted to desired height, by original fixing piece --- first fixes
Part 30 is detached with building structure, then by another fixing piece --- and the second fixing piece 50 carries out attached wall with building structure and fixes,
Then start lifting gear 20, can realize and successively lift.
To describe in more detail its operation principle, the present embodiment is illustrated for being promoted：
As shown in Fig. 2, current whole device is in lower floor, as lowest point is located at the positions 1F.At this point, first is fixed
Part 30 carries out attached wall with building structure and fixes, and the first fixing piece 30 is fixed on higher position position, the positions 3F as shown in Figure 2；
At this point, starting the driving motor 21, driving motor 21 rotates forward, clockwise direction as shown in Figure 2, chain 22, transmission rope 60
It is driven along mode shown in Fig. 2, to drive lifting gear 20, the second fixing piece 50, scaffold main body 10, tensioning apparatus
40 are lifted up.
When lifting gear 20, the second fixing piece 50, scaffold main body 10, tensioning apparatus 40 are elevated a floor,
Integrality is as shown in Figure 3：The lowest point of its whole device is located at the positions 2F, and the second fixing piece 50 is located at the positions 4F；At this point, will
First fixing piece 30 is detached with building structure, and then the second fixing piece 50 is fixed in the building structure of the positions 4F, is then driven
Dynamic motor 21 is inverted by counter clockwise direction as shown in Figure 3 so that chain 22, transmission rope 60 along direction shown in Fig. 3 into
Row transmission, drives lifting gear 20, the first fixing piece 30, scaffold main body 10, tensioning apparatus 40 to be lifted up.
When lifting gear 20, the first fixing piece 30, scaffold main body 10, tensioning apparatus 40 are elevated a floor,
Integrality is as shown in Figure 4：The lowest point of its whole device is located at the positions 3F, and the first fixing piece 30 is located at the positions 5F, at this point, will
Second fixing piece 50 is detached with building structure, and the first fixing piece 30 is then fixed on the positions 5F, then sequentially repeats above-mentioned step
Suddenly, it can successively be promoted.During being somebody's turn to do, basic ideas are to fix the first fixing piece 30 and the second fixing piece 50 by turns,
Then it is inverted by controlling the rotating forward of driving motor 21, another loose fixing piece of promotion by turns and scaffold main body
10, to realize the purpose successively promoted.
When needing to carry out step-down operation, basic principle is same as above, and when decline need to only control the rotation side of driving motor 21
To reversed opposite with rotation when being promoted.
Although being disclosed to the present invention by above example, the scope of the invention is not limited to this,
Under conditions of present inventive concept, above each component can with technical field personnel understand similar or equivalent element come
It replaces.
