Background technology
China has more than 1.2 hundred million urban family at present, and the speed with annual 2400 ten thousand families increases severely, yet residence, city per capita the extremely low high speed development people along with China's economic society to buy goods more and more, the article that people buy need to push up bought cargo storage in cabinet, closet, equal-height position.For supermarket, a large amount of goods need to be placed on the shelf of eminence, client also need to be from the overhead commodity of taking.Moreover these electric mountings such as lamp of air conditioner, at top ceiling equal-height position, need people to keep in repair aloft if these electrical equipment break down.For addressing these problems traditional method, be to make people can take, deposit and keep in repair with ladder, use function singleness and inconvenience.
21 century is high-tech epoch, when rhythm of life is fast, people start the requirement of surroundings also more and more higher, multifunctional household lift cart can not only be realized lifting like this, can also be used as shopping cart uses, and for narrow and small town house space, depositing of dolly is flexible, institute takes up space not quite, is applicable to people for the pursuit of " brief and remarkable life ".
Summary of the invention
The object of the present invention's design is to provide multifunctional household lift cart, this multifunctional household lift cart has elevating function, and this multifunctional household lift cart also has the function of carrying transportation article simultaneously, has higher work efficiency and alerting ability, but also it is simple to have connecting rod mechanism, conduct oneself with dignity little, volume is little, cheap, practical, the advantages such as maintaining is simple, and movement inertia is little, low-noise pollution-free.
The present invention achieves the above object by the following technical programs:
Multifunctional household lift cart, comprises running gear, the first lifting side chain, the second lifting side chain, the 3rd lifting side chain and workplatform.
The first lifting side chain is comprised of the first driving lever 4, first connecting rod 3, first driving lever 4 one end are by being connected with running gear 6 front end of the top surface by the first fraising 7, the other end is connected with first connecting rod 3 by the second fraising 18, and first connecting rod 3 other ends are connected with workplatform bottom surface front end by the 3rd fraising 16; The second lifting side chain is comprised of the second driving lever, second connecting rod, second driving lever one end is by being connected with the left back end of running gear end face by the 4th fraising, the other end is connected with second connecting rod by the 5th fraising, and the second connecting rod other end is connected with the left back end in workplatform bottom surface by the 6th fraising; The 3rd lifting side chain is comprised of the 3rd driving lever, third connecting rod, the 3rd driving lever one end is by being connected with running gear end face right rear end by the 7th fraising, the other end is connected with third connecting rod by the 8th fraising, and the third connecting rod other end is connected with workplatform bottom surface right rear end by the 9th fraising
The first driving lever, the second driving lever, the 3rd driving lever are driven by the first servomotor torque constant, the second servomotor torque constant, the 3rd servomotor torque constant that are arranged on running gear respectively.By the first servomotor torque constant, the second servomotor torque constant, the 3rd servomotor torque constant, drive and drive respectively the first driving lever, the second driving lever, the 3rd driving lever to rotate, the first driving lever, the second driving lever, the 3rd driving lever drive first connecting rod, second connecting rod, third connecting rod to rotate, and then realize the lifting of workplatform.Workplatform surrounding has backplate, and base plate can be for convenience detach.Bench board and the first lifting side chain, the second lifting side chain, the 3rd lifting side chain, be connected by pin between the first lifting side chain, the second lifting side chain, the 3rd lifting side chain and running gear, thereby can realize for convenience detach.
Outstanding advantages of the present invention is:
1, adopted easy connecting rod mechanism, not only save cost, and significantly reduced the weight of lifting mechanism part, improved the reliability of shaft portion, reduced the movement inertia of mechanism, there is good kinematics and dynamic performance.
2, the connecting rod mechanism that this lifting mechanism is driven by servomotor torque constant has replaced conventional hydraulic transmission, has reduced manufacturing cost, is easy to maintaining simultaneously, because each driving lever is driven by servomotor torque constant, not only be easy to programming Control, practical, and also operating speed variable range is wide, operating efficiency is high, have good alerting ability, speed of response is fast simultaneously, can be widely used in elevator.
3, because multifunctional household lift cart servomotor can adopt storage battery power supply, not only avoided the dependence to non-renewable energy resources such as oil, be beneficial to environmental protection, but also can under the particular surroundingss such as high altitude anoxia, carry out construction operation, while working due to servomotor, noise is low simultaneously, has reduced the noise pollution of construction to surrounding environment.
