Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in Figure 1, the self-propelled transport trolley that what the utility model provided utilize elastic potential energy to drive, comprise base plate 1, above described base plate 1, rear and front end is separately installed with clockwork spring 3, is fitted with rotating shaft 6 in the middle part of clockwork spring 3, and rotating shaft 6 two ends are connected with roller 5; Corner place, described base plate 1 top is connected with mount pad 2 respectively, mount pad 2 top is fitted with the guidepost 4 vertically arranged, also comprise top board 12, corner, top board 12 top is provided with mount pad 2 equally, guidepost 4 top is through the mount pad 2 that top board 12 is installed, be connected with bottom top board 12 one end and the riser 10 vertically arranged down, riser 10 inside middle portion is connected with tooth bar 9, base plate 1 side is provided with retarder 8, the rotating shaft 6 of homonymy is through this retarder 8, and retarder 8 top is provided with the gear 11 be meshed with tooth bar 9.Lower coping 12 after weight 13 is placed on top board 12, the tooth bar 9 on riser 10 drives the gear 11 be meshed with it to rotate, and gear 11 drives the gear cluster in retarder 8 to rotate, and then drive shaft 6 and roller 5 rotate, and realize movement of the present utility model.
In order to ensure gravitational potential transformation of energy and the storage of weight 13, and also will ensure the stationarity of movement, avoiding occurring that moment of torsion is unbalance, the clockwork spring 3 that described rotating shaft 6 is installed has two.
Too much cause riser 10 to collide base plate 1 in order to avoid top board 12 moves down, described guidepost 4 is connected with limiting stopper 7.
In order to avoid riser 10 bottom collision base plate 1, the height of the distance >=riser 10 on described limiting stopper 7 and guidepost 4 top.
During work:
As shown in Figure 2, weight 13 is placed on after on top board 12 and moves to position 2 with self-propelled floor truck from position 1, weight 13 is placed on lower coping 12 after on top board 12, tooth bar 9 on riser 10 drives the gear 11 be meshed with it to rotate, gear 11 drives the gear cluster in retarder 8 to rotate, and then drive shaft 6 and roller 5 rotate, rotating shaft 6 drives clockwork spring 3 rotary tightening at rotation process, now, the gravitional force of weight 13 is used for driving the utility model move and be stored in clockwork spring 3 by part potential energy.Weight 13 is taken off behind in-position 2, dolly turns back to position 1 from position 2 again, return to initial position, Recovery Process as shown in Figure 3, after weight 13 takes off, the deadweight of top board 12 is not enough to drive shaft 6 and rotates, now, the potential energy be stored in clockwork spring 3 is released in rotating shaft 6, two rotating shaft 6 synchronous axial system, the rotating shaft 6 of front end drives the roller 5 at its two ends to rotate, the gear cluster in retarder 8 is driven to rotate when the rotating shaft 6 of rear end is rotated, the gear 11 on final driving retarder 8 top rotates, along with the rotation of gear 11, the stressed rising of tooth bar 9 be meshed with it, and then drive riser 10 and top board 12 together lifting.
The constraint equation of this system can be expressed as:
( m 1 + m 2 ) gh = 1 2 ( m 1 + m 2 + m 3 ) ( v 2 - v 1 ) 2 + 1 2 k ( δ 1 - δ 2 ) 2 + W f - - - ( 1 )
1 2 k ( δ 1 - δ 2 ) 2 = 1 2 ( m 2 + m 3 ) ( v 1 ′ - v 2 ′ ) 2 + m 3 gh + W f - - - ( 2 )
In formula:
M 1: weight 12 quality;
M 2: self-traveling trolley quality;
M 3: top board 12 quality;
G: acceleration due to gravity;
H: the whole story, position height was poor;
V 1, v 2: the speed of dolly when first position and last position in handling process;
K: spring constant;
δ 1, δ 2: the spring deflection of object when first position and last position;
V 1', v 2': the speed of dolly when first position and last position in dolly return course;
W f: dolly is friction working in the process of moving.
Known by foregoing, the utility model, in raising degree of automation, reduces in labor cost, reduction energy consumption and has significant role.
