The working principle of the invention is as follows: the length of the telescopic arm is regulated by the telescopic mode converter, the fork is driven by the transmission between the rotary regulating gear and the driving gear to put the object on the horizontal plane of the fork, and the telescopic arm is regulated again to make the gravity center of the object on the driven wheel or regulate the distance between the bracket and the ground, so that the gravity center is lowered, and the purposes of stability, balance and portability are achieved; the lifting rod is adjusted to realize the transfer of the object between the low place and the high place, and the longer the distance between the arm length and the supporting point is, the more labor-saving is based on the lever principle. The horizontal device of the fork forms a circuit through mercury and switches on the front side and the rear side, and when the plane of the fork is not horizontal, the mercury is connected with the circuit to trigger the automatic horizontal device of the fork to adjust the position of an object.

The invention is divided into an upper part and a lower part, wherein the lower part of the mechanical device adopts an aluminum profile as a frame structure, and the upper part is a telescopic arm and a fork (which can be detached and replaced) made of steel, and a lifting rod controlled by a lifting switch. The whole mechanical device utilizes the lever principle to achieve the functions of saving labor, carrying, loading and unloading and the like, and can be used for carrying large-scale express mail on and off vehicles and the like.

The lifting switch controls the lifting of the lifting rod, so that the telescopic arm is lifted and lowered, the gravity center of the heavy object is deviated to incline in the lifting and lowering process of the telescopic arm, the angle between the whole mechanism and the ground can be adjusted, the gravity center of the heavy object is kept on or near a supporting point, and the fork is automatically in a horizontal state through the fork automatic horizontal device, so that the whole mechanism can be controlled with small force, and the best labor-saving effect is achieved. This design improves the inconvenience of traditional manual handling goods getting on or off to alleviateed people's working strength, improved the efficiency of loading and unloading goods, and this work simple structure easily operates, light in weight, small portable places occupation space not.

The design of the fork automatic level device is that two mercury switches are mainly applied to the fork automatic level device, two mercury switches are respectively arranged on two sides of the fork, and when the fork tilts forward, the left mercury switch is touched, so that the drive motor rotates forward to drive the fork to return to a designated position and then is automatically powered off; when the fork leans back, the mercury switch on the right is touched, so that the driving motor rotates reversely to drive the fork to return to the designated position and then the power is automatically cut off. That is, both mercury switches are not energized when the fork is in a nearly horizontal position.

In order to enable goods to be horizontally and stably loaded and unloaded, the fork adjusting mechanism is designed, a gear motor is used for providing power, and the state of the fork is adjusted through gear meshing transmission moment.

The lifting rod 17 is connected between the telescopic arm and the bottom frame, and the lifting rod can control the telescopic arm to ascend and descend. Meanwhile, the telescopic performance of the push rod not only solves the problem of different heights of lifted cargoes, but also can reduce the space occupied by the trolley when the trolley is idle. The mechanism can be used for carrying heavier cargoes across gradients, so that the working intensity of people is reduced.

The invention can be used manually or intelligently controlled:

when in manual use: the manual-automatic mode converter can be adjusted to be in a manual mode, and can be manually controlled. The power driving wheel under the power driving wheel can be folded up during working, the angle between the whole mechanism and the ground can be freely adjusted, the power driving wheel can be folded up and can be used for supporting when carrying cargoes at a long distance, and the driving wheel can not be driven in a manual mode and can only be pushed manually. When the goods on the ground are to be forked and the ground is not covered, the telescopic mode converter can be adjusted to be in a manual control mode, and the stretching and the shrinking of the telescopic arm can be freely controlled, so that the lower goods can be easily forked. The fork-lift truck is then used to adjust the center of gravity to be at or near the support point, and the telescopic arm is used to adjust the boom when the telescopic arm is biased inward when the center of gravity is biased outward, and the angle between the whole mechanism and the ground or the combination of the whole mechanism and the ground can be adjusted. The fork is always automatically positioned at the horizontal position in the whole operation process, and manual adjustment is not needed. The lifting switch controls the electric lifting rod to lift and descend.

Intelligent control uses: the automatic operation can be realized by adjusting the manual-automatic mode converter to an automatic mode. At this time, the central processing unit, the visual sensor and the auditory sensor are started, and the power driving wheel rotates to be in a standby state. In this mode the telescopic mode converter defaults to an automatic control mode which automatically adjusts the centre of gravity of the weight at or near the support point. The central processing unit is provided with a communication module, a GPS positioning module and an azimuth judging module besides processing data. When the automatic sound source is used, the automatic sound source can automatically finish tasks by transmitting picture information and the position of the article to be carried, and when the automatic sound source returns, the automatic sound source can automatically judge the direction of the sound signal and the direction of the sound source.

The beneficial technical effects of the invention are as follows:

the gravity center of the weight is offset when the telescopic arm ascends and descends, and the gravity center of the weight is adjusted on a supporting point by adjusting the angle between the whole mechanism and the ground; the whole mechanism is designed according to the lever principle, and takes the bottom wheel as a fulcrum, so that the purpose of labor-saving carrying is achieved; the fork horizontal device can automatically adjust the rotation of the gear to control the angle between the fork and the ground, so that the fork is always in a horizontal state.
