Bottom is provided with gag lever post, and the gag lever post bottom is fixedly connected through circular hole with transmission case intracavity bottom.
Furthermore, the transmission case side is provided with controller, and the controller is controlled using PLC, the controller
It is connected with motor electric wire.
Furthermore, the fixture block and neck nested encryptions.
Furthermore, the support column both sides are equipped with chute, and pulley is embedded at chute inner chamber.
Furthermore, the two motor synchronous operation, and in the opposite direction.
Furthermore, the support column is provided with graduation mark, the unit use centimetre of the graduation mark.
The utility model beneficial effect：A kind of mechanical ascending and descending platform involved by the utility model, using mechanical liter
Drop principle, using fixture block and the nested encryptions of neck, support platform can be lifted, thus by article raised or under
Drop, it is simple in construction, it is reasonable in design, by the cooperation of pulley and chute, support column off normal can be prevented, by setting limiting plate,
It can not only further prevent support column from occurring off normal, while can also be stopped when platform raises certain limit, keep away
Exempted from motor to be operated, departed from fixture block and neck, it is safe, by setting graduation mark, can feed back lifting or
The height of reduction, improves accuracy, practical.

Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As Figure 1-Figure 2, a kind of mechanical ascending and descending platform, including firm banking 1, the top of firm banking 1 is provided with
Transmission case 2, the top of transmission case 2 is provided with land groove 3, and the intracavity bottom both sides of land groove 3 are described provided with perforation 4
4 inwall both sides perforate by support frame connection pulley 5, the inner chamber of land groove 3 is provided with support platform 6, the support platform 6
Bottom is fixed with multiple fix bars 8, the side of support column 7 provided with two support columns 7 between two support columns 7
Neck 9 is uniformly offered from top to bottom, and the side of support column 7 is provided with rotating disk 10, and the surrounding of rotating disk 10 is uniformly provided with fixture block
11, the side of rotating disk 10 is provided with motor 12, and two bottoms of support column 7 are equipped with stopper slot 13, the stopper slot
13 inner chambers are provided with limiting plate 14, and the bottom of stopper slot 13 is provided with circular hole, and the bottom of limiting plate 14 is provided with gag lever post 15, and institute
The bottom of gag lever post 15 is stated to be fixedly connected with the intracavity bottom of transmission case 2 through circular hole.
The side of transmission case 2 is provided with controller 16, and the controller 16 is controlled using PLC, and small volume is quick on the draw,
The controller 16 is connected with the electric wire of motor 12, by controller 16 control motor 12 operate, the fixture block 11 with
The nested encryptions of neck 9, can be lifted support column 7, and the both sides of support column 7 are equipped with chute, and pulley 5 is embedded at cunning
Groove inner chamber, can prevent the off normal of support column 7, two motors 12 are run simultaneously, and direction phase during rise
Instead, the support column 7 is provided with graduation mark 17, and the height of lifting or reduction, the graduation mark can be fed back by graduation mark 17
17 unit improves accuracy using centimetre.
Utility model works principle：First, it would be desirable to which the article being lifted is placed into support platform 6, control is passed through
The control motor 12 of device 16 works, and motor 12 drives rotating disk 10 to rotate, on the fixture block 11 on rotating disk 10 and support column 7
The nested encryptions successively of neck 9, so as to drive support platform 6 to be risen together support column 7, support column 7 while rising,
Pulley 5 is slided in chute, and due to the cooperation of pulley 5 and chute, the off normal of support column 7 can be prevented during rise, is led to
Scaleover line 17 can feed back the height of lifting or reduction, and when the height of support column 7 reaches capacity, limiting plate 14 stops spacing
Block, the control motor 12 of controller 17 stops, and blocks rise, the effect of limiting plate 14 can not only further prevent support column
7 occur off normals, while can also be stopped when support platform 6 raises certain limit, it is to avoid motor 12 continues
Operated, fixture block 11 is departed from neck 9, it is safe.
It is above the utility model preferably embodiment, the utility model those skilled in the art can also be to upper
State embodiment to be changed and changed, therefore, the utility model is not limited to above-mentioned embodiment, every ability
