Abstract
Specifically a kind of push and pull system for multi-stage elevation platform of the invention, including intermediate connecting rod group, elect oil cylinder and linking arm, the one end for electing oil cylinder is rotatablely connected by linking arm with intermediate connecting rod, and the pedestal of the other end and hoistable platform of electing oil cylinder is slidably connected, it is characterized in that：Length 1 shared by oil cylinder is elected under the total height h of intermediate connecting rod group, contraction state, and following formula calculating is respectively adopted, h=2Lsin α+xsin α-ysin α=(2L+x-y) sin α l=Lcos α-xcos α-ycos α=this push and pull system of (L-x-y) cos α is using above-mentioned design, pass through the length of single intermediate connecting rod, the required weight for electing aluminium volume, it can accurately obtain the design size needed for a whole set of push and pull system and hoistable platform, provide convenience to provide multilevel scaling platform in small space.
Description
Technical field
The present invention relates to automation equipment field, specifically a kind of push and pull system for multi-stage elevation platform.
Background technology
The file of Patent No. 201420088492.X discloses a kind of for transporting and being lifted coiled material or tubing, plate automatically
The travelling bogie of material, the application scenario of such travelling bogie is mostly narrow space, height-limited but changeable occasion.Due to height
Degree is limited, therefore the gap between the minimum altitude of travelling bogie and maximum height is big.To which existing push and pull system application is herein
The problem of cannot achieve multistage lifting is there is on class travelling bogie.
Invention content
The object of the present invention is to provide a kind of push and pull system for multi-stage elevation platform, can be in small space
The middle purpose for realizing multistage lifting.
In order to achieve the above object, the invention is realized in this way：
A kind of push and pull system for multi-stage elevation platform, including multigroup intermediate connecting rod group arranged in a crossed manner, an election
Oil cylinder and a linking arm, the one end for electing oil cylinder are rotatablely connected by linking arm with intermediate connecting rod, and the another of oil cylinder is elected
The pedestal with hoistable platform is held to be slidably connected, it is characterized in that：Oil cylinder institute is elected under the total height h of intermediate connecting rod group, contraction state
It accounts for length 1 and following formula calculating is respectively adopted,
H=2Lsin α+xsin α-ysin α=(2L+x-y) sin α
1=Lcos α-xcos α-ycos α=(L-x-y) cos α
Wherein, L is the length of single intermediate connecting rod, angles of the α between single intermediate connecting rod and hoistable platform pedestal, x
For the length of linking arm, y is to elect oil cylinder at a distance from hoistable platform pedestal side wall.
The push and pull system for multi-stage elevation platform elects the reasoning provided needed for oil cylinder and uses following formula meter
It calculates：
F=GLcos α (1+4sin2 α)/2xsin (alpha+beta)
Wherein, G is the weight after hoistable platform its own gravity is rolled up plus aluminium, and β is that oil cylinder and hoistable platform are elected under α states
Angle between pedestal.
This push and pull system uses above-mentioned design, the weight rolled up by the length of single intermediate connecting rod, required election aluminium,
Accurately obtain the design size needed for a whole set of push and pull system and hoistable platform, it is flexible to provide multilevel in small space
Platform is provided convenience.
Description of the drawings
Fig. 1 is this push and pull system size relationship schematic diagram.
Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1, a kind of push and pull system for multi-stage elevation platform, including multigroup intermediate connecting rod arranged in a crossed manner
Group, an election oil cylinder and a linking arm, the one end for electing oil cylinder are rotatablely connected with intermediate connecting rod by linking arm, are elected
The other end of oil cylinder and the pedestal of hoistable platform are slidably connected, it is characterized in that：Under the total height h of intermediate connecting rod group, contraction state
It elects length 1 shared by oil cylinder and following formula calculating is respectively adopted,
H=2Lsin α+xsin α-ysin α=(2L+x-y) sin α
1=Lcos α-xcos α-ycos α=(L-x-y) cos α
Wherein, L is the length of single intermediate connecting rod, angles of the α between single intermediate connecting rod and hoistable platform pedestal, x
For the length of linking arm, y is to elect oil cylinder at a distance from hoistable platform pedestal side wall.
The push and pull system for multi-stage elevation platform elects the reasoning provided needed for oil cylinder and uses following formula meter
It calculates：
F=GLcos α (1+4sin2 α)/2xsin (alpha+beta)
Wherein, G is the weight after hoistable platform its own gravity is rolled up plus aluminium, and β is that oil cylinder and hoistable platform are elected under α states
Angle between pedestal.
This push and pull system uses above-mentioned design, the weight rolled up by the length of single intermediate connecting rod, required election aluminium,
Accurately obtain the design size needed for a whole set of push and pull system and hoistable platform, it is flexible to provide multilevel in small space
Platform is provided convenience.
