It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that, in the description of the present invention, the directions indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. are relative to the vertical state of the frame in the drawings when lifting goods, which is merely for convenience of description and should not be construed as limiting the present invention.

Example 1:

a multifunctional balance transport vehicle is shown in figure 1 and is in a trolley shape and comprises a chassis 1, a beam 2 and a lifting shelf. The chassis 1 is connected with the box that is inverted triangle-shaped between a pair of walking wheels including a pair of walking wheels of coaxial setting, and inverted triangle-shaped's box has great approach angle and leaves the angle, is favorable to cross-country trafficability characteristic. A storage battery, a driving motor and a control circuit are arranged in the box body. Two driving motors are arranged, the two driving motors are respectively connected with a pair of walking wheels through a speed reducer, and a control circuit controls the driving motors through a gyroscope and an acceleration sensor to keep the stability of the balance transport vehicle during walking.

The shaft 2 is connected to the chassis 1, and for convenience of control, a pair of operation levers 6 are connected to the right end of the shaft 2, and a plurality of control switches are mounted on the operation levers 6.

The lifting shelf is connected to the shaft 2 for lifting and carrying goods and comprises a frame 3 with a bottom plate 302, a fork 4 and a winch 5. The lower end of the frame 3 is hinged at the left end of the shaft 2, the width of the frame 3 is smaller than that of the shaft 2, when the frame 3 is laid down to the right, the frame 3 falls into the shaft 2 and is supported by the top surface of the box body. Frame 3 totality is square frame shape, is formed by the channel-section steel welding, and the notch of channel-section steel inwards sets up, and a set of notch relative around is used for the restriction to set up the gyro wheel at 4 both ends of fork, makes fork 4 only can reciprocate along the notch. A bottom plate 302 is welded to the bottom of the frame 3, and the bottom plate 302 is used to carry cargo when the frame 3 is laid down.

As shown in fig. 2, a landing leg 301 is welded to the lower end of the frame 3, and when the cargo is lifted, the balance system needs to be closed to land the left shaft 2, and the frame 3 is turned over to land the landing leg 301, so that the landing leg 301 expands the supporting area of the lifting shelf, and the lifting of the cargo is more stable. In order to reduce the sliding resistance of the landing leg 301 when the goods are picked up by the fork, a roller is mounted on the landing leg 301, and when the goods are picked up by the fork, the roller lands on the ground to roll and support the lifting shelf. The winch 5 is arranged at the upper end of the frame 3 and is connected with the fork 4 through a steel wire rope 501, when goods are lifted, the winch 5 rotates, and the fork 4 moves up and down along the frame 3 under the driving of the winch 5. When the fork 4 picks up the goods through the lifting fork and lifts the goods to a proper height, the frame 3 is turned rightwards, the goods fall on the top surface of the box body along with the frame 3, the balance system is opened after the center of gravity of the goods is roughly ensured to be at the center position of the vehicle body, the balance transport vehicle automatically balances to enable the goods to be in a horizontal state, and the loading operation is completed. The unloading operation is the reverse of the loading operation and will not be described again here.

This transport vechicle also can transport the goods as fork truck, gets the goods back at the fork, and two walking wheels can realize walking and differential turn under driving motor's drive separately, have expanded service function.

When the goods fall down along with the frame 3, the goods are liable to impact the top surface of the box body, in order to reduce the impact and prevent the goods from being damaged, the balance transport vehicle also comprises a self-telescopic support rod 7 (an air spring), one end of the self-telescopic support rod 7 is hinged with the beam 2, and the other end is hinged with the frame 3. When loading, the self-telescopic stay bar 7 can reduce the impact on the goods; when unloading, the self-telescopic supporting rod 7 can assist an operator to erect the frame 3 with the goods, and in addition, the self-telescopic supporting rod 7 can also ensure the stability of the frame 3 when erecting, so that the frame 3 is prevented from being accidentally overturned when the goods are lifted.

Example 2:

in embodiment 1, the lifting height of the fork 4 is not large, limited by the length of the frame 3, and there is a limitation in application. For this reason, there is a continuing need for improved solutions.

Unlike embodiment 1, the multifunctional balance transporter in embodiment 1 is that, as shown in fig. 3, the frame 3 is a folding frame 3, and includes a main frame 303 with a bottom plate 302 and a gate-type sub-frame 304 without the bottom plate 302, the lower end of the main frame 303 is hinged to the left end of the beam 2, and the upper end of the main frame 303 is hinged to the sub-frame 304 through a hinge.

In this embodiment, the lifting height of the forks 4 is increased by the upward expansion of the sub-frame 304. In order to prevent the sub-frame 304 from rotating when lifting goods, a hook limiting mechanism 305 is arranged near the hinged position, specifically, as shown in fig. 4, a hook is hinged on the main frame 303, a clamping pin is fixed on the sub-frame 304, when the sub-frame 304 is collinear with the main frame 303, the end surface of the sub-frame 304 is aligned with the end surface of the main frame 303, and at the moment, the hook is rotated to be clamped on the clamping pin, so that the sub-frame 304 is limited to rotate.

Since the sub-frame 304 is the gate frame 3 without the bottom plate 302, the cargo on the main frame 303 does not affect the unfolding and folding of the sub-frame 304. But because hoist 5 is heavier, it is harder to overturn. Therefore, the technical scheme is continuously improved, the winch 5 is arranged on the box body, the first pulley 8 is arranged at the free end of the auxiliary frame 304, the second pulley 9 is arranged at the lower end of the main frame 303, and the steel wire rope 501 of the winch 5 is connected with the pallet fork 4 sequentially through the reversing of the second pulley 9 and the first pulley 8. The second pulley 9 reverses the steel wire 501, so that the overturning moment of the winch 5 to the lifting goods shelf in the right direction is reduced, and the stability of the lifting frame 3 is improved. Therefore, the problem that the winch 5 is difficult to overturn is solved, and electric devices including the winch 5 are placed in a centralized mode.

Example 3:

in embodiment 1, the shaft 2 is symmetrical with respect to the chassis 1, so that the frame 3 is turned over at a large angle when loading or unloading, and an operator needs to take a lot of effort when turning over the frame 3, especially when loading or unloading. For this reason, there is a continuing need for improved solutions.

The multifunctional balance transport vehicle according to embodiment 1 is different from embodiment 1 in that a sliding groove extending in the direction of the shaft 2 is provided on the shaft 2, and a slider corresponding to the sliding groove is provided on the chassis 1, so that the shaft 2 can slide left and right on the chassis 1 when loading and unloading goods. In order to provide sliding power by using the winch 5, a first pulley 8 and a second pulley 9 are respectively arranged at the upper end and the lower end of the frame 3, the winch 5 is arranged on the box body of the chassis 1, and a steel wire rope 501 of the winch 5 is sequentially connected with the pallet fork 4 through the reversing of the second pulley 9 and the first pulley 8.

As shown in fig. 5, when unloading, the fork 4 is connected and fixed with the frame 3 by using the fixing bolt 11, then the balance system is closed, the left end of the beam 2 is landed under the action of the gravity center, and then the winch 5 is opened to tighten the steel wire rope 501. Since the fork 4 cannot move relative to the main frame 303, the beam 2 moves rightward relative to the chassis 1 under the action of the steel wire 501, so that the included angle between the beam 2 and the frame 3 becomes smaller gradually, and at the moment, the frame 3 and the goods can be erected by applying a smaller force.

In order to realize the reverse operation during loading, as shown in fig. 6, a rotating shaft is provided at a position near the right end of the shaft 2, and a third pulley 10 is provided on the rotating shaft. During loading, the winding direction of the wire rope 501 is adjusted, and the wire rope 501 of the winch 5 is connected with the fork 4 through the reversing of the third pulley 10, the second pulley 9 and the first pulley 8 in sequence. When the winch 5 tightens the wire 501 due to the reversing of the third sheave 10, the beam 2 moves leftwards relative to the chassis 1, and the two ends of the beam 2 are restored to balance. The gravity center of the goods is hinged through the winch 5, and the beam 2 is fixed on the box body of the chassis 1 through bolts after the gravity center of the whole vehicle is balanced.

Therefore, the winch 5 is used for driving the shaft 2 to slide on the chassis 1, the gravity center of the whole vehicle is lowered, the moment of erecting or laying the frame 3 is reduced, the gravity center of goods can be hinged through the winch 5, and extra burden on a driving motor due to unbalance is reduced.

In the above operation, the shaft 2 slides to the right relative to the chassis 1 to cause the operating rod 6 to be too high, which brings inconvenience to the operator, and for this reason, the technical solution is continuously improved, in which the connection between the operating rod 6 and the shaft 2 is a multi-position rotary connection. Specifically, as shown in fig. 7, a toothed sector plate 201 having a plurality of teeth grooves is provided on the shaft 2, a stopper push rod 601 corresponding to the teeth grooves is provided in the operating lever 6, and the stopper push rod 601 is slidable in the operating lever 6. A lever is provided on the stop plunger 601, which lever projects out of the operating lever 6 through a slot provided in the operating lever 6. A compression spring 602 is connected to the right end of the stopper rod 601, and under the action of the compression spring 602, the tapered head of the stopper rod 601 is inserted into the tooth groove of the toothed sector plate 201, so that the operating rod 6 cannot rotate. When the operating rod 6 is to be adjusted, an operator pushes the operating handle rightwards to enable the conical head part of the stopping push rod 601 to be separated from the tooth groove of the toothed sector plate 201, at the moment, the operating rod 6 can rotate, when the operating handle is rotated to a proper position, the operating handle is loosened, and the conical head part of the stopping push rod 601 is inserted into the corresponding tooth groove of the toothed sector plate 201, so that the operating rod 6 cannot rotate any more.
