Abstract

The utility model discloses a helix scissor hoisting platform which comprises a base frame 1 and a hoisting platform, wherein a flexible scissor arm 11 is hinged with a put scissor arm 13 at the middle position; the put scissor arm 13 and the top of the flexible scissor arm 11 are all hinged with the helix scissor hoisting platform; the bottom of the put scissor arm 13 is hinged with a base frame 1; the bottom of the flexible scissor arm 11 is equipped with a roller 12;an elastic coupler 4 connects an AC motor with a speed reducer 5 which is connected with a secondary gear 7 meshing a primary gear 9 having a put connection with a nut 8 which is sleeved at the base frame and connected with a trapezoidal screw 2 which has a hinge connection with one end of a connection plate 10 the other end of which has a hinge connection with the flexible scissor arm 11. The utility model is mainly used for a lifting operation at a production line and an automatically operated line for a conveyance at different height, a material loading or unloading, a workpiece assembly, decoration and fitting, a school or a showplace.

Description

Spiral is cut and is forked heavy platform
Affiliated technical field
The utility model relates to a kind of platform hoisting device, and especially a kind of spiral is cut and forked heavy platform.
Background technology
At present, known lifting platform structure is made up of scissors mechanism, hydraulic ram, hydraulic circuit system, control electric wiring system.Be that electric energy is converted into fluid pressure by motor and Hydraulic Pump, thereby driving oil cylinder promote scissors mechanism with weight jack-up.But, Hydraulic for lifting load platform structure complexity, the maintenance cost height, pressure maintaining performance is poor, and self-locking property is poor, can not weight is long-term from locking in arbitrary position in the stroke.
Summary of the invention
For overcome existing cut fork heavy platform can not be with weight from locking in the too high deficiency of arbitrary position, manufacturing cost and maintenance cost in the stroke, the utility model provide a kind of can be easily with weight from locking in arbitrary position in its stroke, and make and safeguard that simple spiral is cut and fork heavy platform
A kind of spiral described in the utility model is cut and is forked heavy platform, comprise underframe 1, lifting platform, activity is cut yoke 11 and is fixedly cut yoke 13 and be hinged at the middle part, fixedly cutting yoke 13, activity, to cut the top of yoke 11 all hinged with lifting platform, bottom and the underframe 1 of fixedly cutting yoke 13 are hinged, roller 12 is arranged at the bottom that yoke 11 is cut in activity, it is characterized in that: alternating current dynamo 3 is by elastic coupling 4 connection reducers 5, retarder 5 connects second gear 7, first gear 9 is meshed with second gear 7, and first gear 9 is fixedly connected with the empty nut 8 that is enclosed within on the underframe 1; Nut 8 interconnects with Acme thread bar 2; Acme thread bar 2 is hinged with gusset piece 10 1 ends, and it is hinged that yoke 11 is cut in gusset piece 10 other ends and activity.
When motor rotates, slow down by retarder, power is reached gear 2, by engagement, gear 2 is passed to gear 1 with power, and gear 1 drives nut and rotates, thereby makes Acme thread bar drive activity cut yoke, reaches the purpose that promotes weight.When lifting platform stopped, nut 8 constituted self-locking mechanism with Acme thread bar 2.
The beneficial effects of the utility model are: can easily weight be locked in arbitrary position in the process certainly in the lifting weight, simple in structure, reliable, maintenance cost is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is an appearance assumption diagram of the present utility model.
Fig. 2 is that spiral is cut and forked heavy platform and cut open the cutaway view of putting behind the thing platform.
Fig. 3 is that spiral is cut the work comparison diagram that forks heavy platform original position and extreme higher position.
Fig. 4 is the actuating unit scheme drawing.
The specific embodiment
With reference to accompanying drawing:
1. underframe among the figure, 2. Acme thread bar, 3. alternating current dynamo, 4. elastic coupling, 5. retarder is 6. put the thing platform, and 7. gear 2,8. nut, 9. gear 1,10. gusset piece, yoke is cut in 11. activities, 12. rollers, 13. fixedly cut yoke.
Alternating current dynamo 3 is fixed on the underframe 1, alternating current dynamo 3 mouths connect with retarder 5 by elastic coupling 4, the second gear gear 7 is fixed with retarder 5 mouths and is meshed with first gear 9, first gear 9 is fixedly connected with the empty nut 8 that is enclosed within on the underframe 1, the hinged thing platform 6 of putting of yoke 11 1 ends is cut in activity, it is middle with fixedly to cut yoke 13 centres hinged, the hinged roller 12 of the other end is supported on the underframe 1, it is hinged fixedly to cut yoke 13 lower ends and underframe 1, the thing platform is put 6 times with roller 12 hinged being supported in the upper end, it is hinged that yoke 11 is cut in gusset piece 10 1 ends and activity, and the other end and Acme thread bar 2 are hinged, and Acme thread bar 2 cooperates connection with nut (8).
When motor rotates, slow down by retarder, power is reached gear 2, by engagement, gear 2 is passed to gear 1 with power, and gear 1 drives nut and rotates, thereby makes Acme thread bar drive activity cut yoke, reaches the purpose that promotes weight.When lifting platform stopped, nut 8 constituted self-locking mechanism with Acme thread bar 2.
