Fig. 3 is the structural representation of an embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1,2 and 3, the liftable scaffold that the utility model proposes, comprise support body 1, carrying platform 3, drive motors 7, reduction gear box 8, driving shaft 9, support body is frame shape, and each pillar 101 lower end of support body has universal wheel 2; One section of U-type groove rail 102 established along its length by pillar 101, and the bottom land of U-type groove rail 102 is provided with rack structure 103; The bottom, two ends of carrying platform 3 is respectively equipped with front rotary shaft 4 and rear rotating shaft 5, and the two ends of front rotary shaft 4 and rear rotating shaft 5 are all provided with lifter wheel 6, and each lifter wheel 6 correspondence is meshed with the rack structure 103 of every section of U-type groove rail 102; Drive motors is fixed on described carrying platform 3; Reduction gear box 8 is fixed on carrying platform, and the output wheel 71 of drive motors is connected with the input belt pulley 81 of reduction gear box 7 by belt; Driving shaft is located at the bottom of carrying platform 3 near the position of front rotary shaft 4, the two ends of driving shaft 9 are provided with the driving gear 10 engaged with lifter wheel 6, and this driving shaft 9 is also provided with the first drive sprocket 11 and the second drive sprocket 12, first drive sprocket 11 is connected with the output chain gear 82 of top reduction gear box 8 by chain; And the second drive sprocket 12 is mounted on the driven sprocket 13 in rear rotating shaft by chain; Drive motors 7 and reduction gear box 8 are all with automatically embracing toothing.
Carrying platform 3 is also provided with and level gauge, and the side of carrying platform 3 is hinged with external expanding plate 15.The bottom of rack structure 103 is provided with spacing fixture block 16, and spacing fixture block 16 is provided with travel switch.
During specific works, drive motors works, output wheel 71 rotates, output wheel 71 is belt pulley, input belt pulley 81 is driven to rotate, thus output chain gear 82 rotates, output chain gear 82 is rotated by the first drive sprocket 11 below chain-driving, first drive sprocket 11 drives whole driving shaft 9 to rotate, two driving gears 10 on driving shaft 9 rotate, two lifter wheels 6 on front rotary shaft 4 are driven to rotate, and the second drive sprocket 12 of driving shaft 9 rotate through chain-driving after driven sprocket 13 in rotating shaft 5 rotate, thus the lifter wheel 6 at rotating shaft 5 two ends rotates after driving, carrying out appropriate design like this, lifter wheel in front rotary shaft and rear rotating shaft just can realize synchronous axial system, coordinating again by lifter wheel and rack structure 103, just can realize moving up and down of whole carrying platform, after completing adjustment, because drive motors 7 and reduction gear box 8 are all with automatically embracing toothing, such one quits work, drive motors 7 and reduction gear box 8 just embrace tooth automatically, gear cannot be rotated, thus the position allowing carrying platform be stabilized in mix up, very easy to use.
During concrete use, refer to Fig. 3, the utility model generally adopts two groups of combinations, may be used for carrying master worker, while for placing fragment of brick, such flexibility, the direction switch of the drive motors on both sides is arranged on the plummer of carrying master worker, adopts pedal type switch, easy to use, motor-driven structure separates by dividing plate, conveniently laying fragment of brick.
In the utility model, pillar 101 can also carry out docking and extend, and to expand the stroke range of carrying platform 3, stroke range is controlled by travel switch.Further, the utility model can not only apply to building by laying bricks or stones of body of wall, can also apply to building decoration engineering, such as, plaster, tile fixing etc.
Above-described embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
