Technical Field

[0001] This utility model relates to the field of freight equipment technology, specifically to an intelligent heavy-duty transport vehicle. Background Technology

[0002] In modern factories, material handling is a heavy and repetitive task. Traditional manual handling is not only inefficient and prone to errors, but also easily leads to worker fatigue due to long hours of work. To improve efficiency and reduce labor costs, more and more factories are starting to use automated guided vehicles (AGVs) to replace some manual handling.

[0003] Patent application number 201811229476.7 discloses a lifting and transporting trolley. By setting up a traveling mechanism and a lifting mechanism, the trolley can transport and lift goods along a preset track, solving the problem of transporting large, medium, or heavy goods. However, the trolley in this technical solution requires the laying of tracks, which not only increases construction costs but also limits the space available for use. The trolley's running trajectory is fixed, and goods cannot be turned on the trolley, making this solution inflexible in transporting goods. Utility Model Content

[0006] Furthermore, the chain drive assembly includes a drive sprocket and driven sprockets disposed on both sides of the drive sprocket. The drive sprocket and the two driven sprockets are respectively connected by two chains. The output end of the motor drives the drive sprocket to rotate through a drive shaft, and the drive shaft is rotatably connected to the base frame.

[0007] Furthermore, two wheels are provided, and the two wheels are rotatably connected to the base frame via driven shafts and the two driven sprockets respectively.

[0008] Furthermore, the walking mechanism is provided with two sets that are symmetrical and operate independently.

[0009] Furthermore, the lifting assembly includes a lifting power unit and a lifting seat disposed at the telescopic end of the lifting power unit. The lifting seat is connected to the bracket, and the lifting power unit is mounted on the base frame.

[0010] Furthermore, the lifting assembly also includes a guide unit, which includes a guide post and a guide sleeve that cooperates with the guide post. The guide sleeve is disposed in a through hole on the base frame. One end of the guide post is connected to the lifting seat, and the other end is slidably connected to the guide sleeve.

[0011] Furthermore, the bracket and the lifting seat are connected by a rotating assembly, which allows the bracket to rotate relative to the base frame.

[0012] Furthermore, the rotating assembly includes a turntable, and a coaxial fixing pin is fixedly installed at the center of the turntable. The protruding end of the fixing pin is rotatably installed in the central hole opened on the lifting seat.

[0013] Furthermore, a number of coaxial bearings are provided between the turntable and the lifting seat to assist rotation and provide support.

[0014] Furthermore, it also includes a wireless remote control system for controlling the movement of the transport vehicle and the lifting of the bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model discloses an intelligent heavy-duty transport vehicle. It utilizes two motors, each driving a wheel located on one side of the vehicle via a chain drive assembly.

[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0022] An intelligent heavy-duty transport vehicle includes a loading mechanism and a traveling mechanism disposed below the loading mechanism. The traveling mechanism is used for moving the entire transport vehicle, and the loading mechanism is used for supporting goods. Both the loading mechanism and the traveling mechanism are connected to a base frame 1.

[0023] The cargo-carrying mechanism includes a bracket 16, a lifting assembly, and a rotating assembly. The bracket 16 is used to support the cargo and can be configured to fit the shape of the transported cargo. It can be a grid platform composed of horizontal and vertical square tubes or a box structure. The lifting assembly is used to drive the bracket 16 to rise and fall, meeting the needs of raising the cargo or retrieving / placing items at a high position. The rotating assembly is used for the relative rotation of the bracket 16 and the base frame 1, facilitating the adjustment of the relative angle of the transported cargo.

[0024] The lifting assembly includes a lifting power unit 2 and a lifting seat 3 disposed at the telescopic end of the lifting power unit 2. The lifting seat 3 is connected to the bracket 16, and the lifting power unit 2 is mounted on the base frame 1. The lifting power unit 2 can be a hydraulic power unit. Specifically, the lifting power unit 2 is a detachable hydraulic jack. A through hole is opened at the center of the base frame 1, and the detachable hydraulic jack is disposed in the through hole and fixedly mounted on the base frame 1. Its telescopic end is vertically upward. By extending or retracting the telescopic end of the lifting power unit 2, the lifting seat 3 is driven to rise or fall. The lifting seat 3 can be a disc-shaped structure. In order to ensure its stability during lifting and lowering, in one embodiment, a guide unit is provided between the lifting seat 3 and the base frame 1. The guide unit includes a guide post 4 and a guide sleeve 5 that cooperates with the guide post 4. Specifically, there are several sets of guide units. Several through holes are also evenly provided around the lifting power unit 2 on the base frame 1. The guide sleeve 5 is installed in these through holes. One end of the guide post 4 is connected to the bottom of the lifting seat 3, and the other end is slidably connected to the guide sleeve 5. The guide sleeve 5 can be a round flange self-lubricating bearing.

[0025] The rotating assembly connects the bracket 16 and the lifting seat 3. By setting up the rotating assembly, the bracket 16 can rotate relative to the base frame 1 and the lifting seat 3. When it is necessary to adjust the angle of the goods on the bracket 16, the bracket 16 can be rotated manually or electrically. In addition, the base frame 1 can be turned without the goods turning, that is, when the traveling mechanism changes its traveling direction, the direction of the goods remains unchanged, which has strong site adaptability. The rotating assembly includes a turntable 6, which can also be a disc-shaped structure. A coaxial fixing pin 7 is fixedly installed in the center of the turntable 6. A center hole is opened in the center of the lifting seat 3, and the protruding end of the fixing pin 7 is rotatably installed in the hole. In use, the bracket 16, the turntable 6, and the fixing pin 7 rotate synchronously. In order to ensure the stability of rotation, several coaxial bearings 8 are set between the turntable 6 and the lifting seat 3 for auxiliary rotation and support.

[0026] The traveling mechanism includes wheels 9 and a motor 10 that drives the wheels 9 to roll. The motor 10 drives the wheels 9 through a chain drive assembly. The wheels 9 are rubber-coated wheels, using rubber or polyurethane tires, which do not damage the factory floor. The motor 10 is a DC geared motor with a large load-bearing capacity.

[0027] The chain drive assembly includes a drive sprocket 11, a driven sprocket 12, a chain 13, a drive shaft 14, and a driven shaft 15. The drive sprocket 11 is driven by a motor 10. Specifically, the output of the motor 10 drives the drive sprocket 11 to rotate via the drive shaft 14, which is rotatably connected to the base frame 1. Two driven sprockets 12 are located on either side of the drive sprocket 11. The drive sprocket 11 is connected to each of the two driven sprockets 12 by two chains 13. Two wheels 9 are provided, each coaxially mounted with one of the two driven sprockets 12 and rotatably connected to the base frame 1 via the driven shaft 15.

[0028] The traveling mechanism is configured with two symmetrical sets. Specifically, the traveling mechanism is configured with two symmetrical sets with the center of the base frame 1 as the center of symmetry, and the motors 10 in the two sets operate independently. When the two motors work synchronously, the transport vehicle can travel in both directions, forward or backward. When the two motors work asynchronously, the transport vehicle can turn in both directions. When only one motor works, the transport vehicle can turn 360° in both directions with the stationary wheel as the center.

[0029] This transport vehicle is powered by a battery and is also equipped with a wireless remote control system for moving the transport vehicle and raising and lowering the bracket 16. The wireless remote control system uses a computer, mobile phone or handheld remote control to automatically control the motor and hydraulic system through the vehicle main control board or PLC to realize the forward, backward and turning of the transport vehicle and the raising and lowering of the bracket 16. This is existing technology and will not be described in detail here.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
