detailed description

The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

Example 1

Referring to FIG. 1 , a cooperative transport trolley includes a transport trolley. The maximum load capacity of the bicycle is 200kg.

The maximum walking speed is 17KM/h, and the three-dimensional height of the bicycle is 0.5m, the width is 0.4m, and the length is 0.8m. The wheels are 8-inch magnesium alloy light alloy wheels and 12-inch low-pressure vacuum rubber tires.

The transport trolley includes a car body, a walking mechanism and a rotating support mechanism.

The vehicle body 6 is a flat floor.

The running mechanism includes a power supply box 5, a pair of driving mechanisms and a pair of wheels 1. The power supply box 5 is a lithium battery with an output voltage of 48V, and is installed on the top of the car body 6 . A pair of wheels 1 are located on both sides of the bottom of the vehicle body 6 and are respectively connected to corresponding driving mechanisms.

The driving mechanism includes a servo motor 4 and a gear box 3 connected in sequence. The servo motor 4 is a DC brushless servo motor with a power of 450W and a rated speed of 3000 rpm, and has a 20-bit incremental photoelectric encoder; the gear box 3 is a planetary Reducer, reduction ratio 1:10. The output shaft of the reduction box 3 is connected to the wheel 1 through the axle flange 2, and the servo motor 4 is connected to the power supply box 5 through wires; the servo motor 4 and the reduction box 3 are installed at the bottom of the car body 6.

The rotation supporting mechanism is arranged on the top of the vehicle body 6 and is positioned above the power supply box 5 . The rotating support mechanism includes a top plate 9 and a support platform 10. The bottom of the top plate 9 is connected to the top of the bottom plate 6 through four upright poles 8; the top plate 9 and the support platform 10 are connected by bearings, and a bearing seat is installed on the top of the top plate 9. , a tapered roller bearing is installed in the bearing seat, and a rotating shaft is installed at the bottom of the support platform 10, and the interference fit between the rotating shaft and the tapered roller bearing enables the supporting platform 10 to rotate freely relative to the top plate 9.

Referring to Fig. 2 and Fig. 3, a loading platform 13 is installed on the supporting platform 10 of the rotating support mechanism of the transport trolley; as can be seen from Fig. 1, the supporting platform 10 is provided with an upwardly protruding boss corresponding to the loading A matching groove is provided on the platform 13, and the loading platform 13 and the support platform 10 are fitted and connected with the boss through the groove. The object to be carried can be directly placed on the loading platform 13 for transportation. When the bicycle is operated independently, insert the latch so that the support platform 10 and the top plate 9 cannot rotate each other.

The loading platform used in this embodiment is relatively small, and is suitable for carrying heavy objects that are not bulky and whose weight is within the load-carrying range of the transport trolley. When the handling trolley turns, it can directly use the differential speed of the two wheels to make omnidirectional turns, and it can achieve no turning radius.

Example 2

Referring to Fig. 4, the cooperative transport trolley includes two transport trolleys. When in use, the bottom of one side of the loading platform 13 is connected to the rotating support mechanism of a transport trolley, and the bottom of the other side of the loading platform 13 is connected to another bottom of the loading platform 13. The rotating support mechanism of a transport trolley.

Other structures are with embodiment 1.

The cooperation of two moving trolleys can keep the whole system stable. Due to the structural advantages, omnidirectional turning can still be achieved without turning radius. The loading platform used in this state is relatively large, and some larger and heavier objects can be transported.

Referring to FIG. 5 , a turning state of two transporting trolleys when cooperatively transporting objects, the two transporting trolleys rotate at a certain angle relative to the loading platform 13 and cooperate with each other to turn, which can meet the needs of various turning radii.

Example 3

Referring to Fig. 6, the cooperative transport trolley includes three transport trolleys. Its installation method and basic operation state are similar to the two-vehicle cooperative movement state. The loading platform used in this state is larger, which is suitable for handling some heavy objects that cannot be carried by the two-vehicle cooperation.
