Description

Technical Field

[0001] This utility model relates to a liftable platform transport vehicle based on Mecanum wheel omnidirectional movement technology, belonging to the field of lift transport vehicles. Background Technology

[0002] Existing transport vehicles are mostly used for handling and transporting goods, but traditional transport vehicles have certain limitations in terms of movement and lifting, especially in environments requiring omnidirectional movement and flexible operation. Traditional transport vehicles struggle to meet the demands for flexibility and versatility. Traditional lifting platforms often employ a single lifting method, which cannot provide sufficient stability and load-bearing capacity. At the same time, the efficiency and precision of lifting actions are also limited, resulting in low work efficiency.

[0003] With technological advancements, Mecanum wheels, as an omnidirectional mobility technology, offer greater flexibility and freedom of movement. However, their structural design and lifting functions have not yet been effectively integrated in applications, particularly in the field of transport vehicles with lifting requirements, where significant technological gaps remain. Furthermore, existing lifting platform transport vehicles often rely on complex hydraulic systems or relatively bulky mechanical structures, resulting in issues such as insufficient structural compactness, complex operation, and uneven load distribution.

[0004] Therefore, a new type of liftable platform transport vehicle based on Mecanum wheel omnidirectional movement technology is needed to overcome the shortcomings of traditional transport vehicles and lifting platforms, and to achieve more flexible and stable omnidirectional movement and lifting functions, so as to improve work efficiency and meet the transportation and operation needs in complex environments. Utility Model Content

[0005] The purpose of this invention is to provide a liftable platform transport vehicle based on Mecanum wheel omnidirectional movement technology, which can effectively solve the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The system includes a frame and a lifting structure mounted on the frame; wherein the lifting structure includes a support plate and a scissor lifting mechanism mounted on the lower end of the support plate; there are two scissor lifting mechanisms, which are mounted on the same horizontal plane; the two scissor lifting mechanisms are connected together by a transmission plate.

[0008] Furthermore: the scissor lifting mechanism includes four bearing seats on the same side. The bearing seats are fixed in pairs to the frame and the support plate respectively. A rotating shaft is provided between each pair of bearing seats. Two transmission arms are fixed on each rotating shaft. The transmission arm on the upper rotating shaft and the transmission arm on the lower rotating shaft are hinged at the middle part by a limiting shaft. A pulley is provided at the other end of the transmission arm. A drive shaft is provided between the two corresponding pulleys.

[0009] Furthermore: a limiting frame is provided on the upper end face of the frame and the lower end face of the bearing plate, and a limiting strip is provided on the top and bottom surfaces of the limiting frame. An annular groove is provided in the middle part of the pulley annular surface, and the limiting strip is inserted into the annular groove.

[0010] Furthermore: a connecting shaft is provided in the middle of the pulley, and mounting holes are provided at both ends of the transmission plate, the mounting holes cooperating with the connecting shaft.

[0011] Furthermore, the scissor lifting mechanism also includes a drive device, which includes a mounting plate mounted on the frame. An electric hydraulic cylinder is provided on one side of the mounting plate, and the piston end of the electric hydraulic cylinder is rotatably connected to the drive shaft located below.

[0012] Furthermore: the frame includes two symmetrical crossbars, with vertical bars at both ends of the crossbars, an inclined bar at the upper end of the vertical bars, a support bar on one side of the inclined bar, and a load-bearing bar on the support bar. When the scissor lifting mechanism is in operation, the lower end face of the load-bearing plate contacts the upper end face of the load-bearing bar.

[0013] The beneficial effects are:

[0014] By employing Mecanum wheel technology, the transport vehicle of this invention can achieve omnidirectional free movement, avoiding the complex operation of steering required by traditional transport vehicles.

[0015] The scissor lift mechanism provides stable support between the chassis and the load-bearing plate, enabling it to stably support heavy loads.

[0029] See Figure 1-5 This is an embodiment of a liftable platform transport vehicle based on Mecanum wheel omnidirectional movement technology according to this utility model;

[0030] The frame 1 of this device features a steel frame structure, providing strong stability and load-bearing capacity. The upper surface of the frame 1 connects to the lifting structure 2, ensuring stability during lifting. Each side of the frame 1 has two symmetrical horizontal bars 11, with vertical bars 12 at both ends and an inclined bar 13 at the top. A support bar 14 is located on one side of the inclined bar 13, and a load-bearing bar 15 is mounted on the support bar 14. The load-bearing bar 15 supports the load-bearing plate 3 of the lifting platform. If the transported goods are heavy, the load-bearing bar 15 can assist the lifting structure 2 in supporting the goods, ensuring stability and safety during transportation.

[0031] Lifting Structure and Scissor Lifting Mechanism: The core component of the lifting structure 2 is the scissor lifting mechanism 4, which achieves platform lifting through two sets of symmetrical scissor lifting mechanisms. Each scissor lifting mechanism 4 includes four bearing seats 41, which are respectively mounted on the frame 1 and the support plate 3. The bearing seats 41 are fixed in pairs at the connection points of the frame 1 and the support plate 3, and the bearing seats 41 between the groups are connected by rotating shafts 42. Two transmission arms 43 are mounted on each set of rotating shafts 42, for a total of four transmission arms 43. The middle part of the transmission arms 43 is hinged by a limiting shaft 44 to ensure stable movement of the transmission arms during lifting.

[0032] Each drive arm 43 has a pulley 45 at its other end, which is connected to the drive shaft 46 on the frame 1. The two corresponding pulleys 45 are connected to each other through the drive shaft 46 to realize the power transmission during the lifting process. A connecting shaft 40 is provided in the middle of the pulley 45, which cooperates with the mounting hole 6 of the transmission plate 5 to transmit power to the transmission plate 5, thereby driving the lifting of another scissor lifting mechanism 4.

[0033] Limiting mechanism and stabilizing device: To ensure the stability of the support plate 3 during lifting, a limiting frame 47 is provided between the upper end face of the frame 1 and the lower end face of the support plate 3. Limiting strips 48 are provided on the top and bottom surfaces of the limiting frame 47, and an annular groove 49 is provided in the middle of the annular surface of the pulley 45. The limiting strips 48 are inserted into the annular groove 49 to ensure that the support plate 3 will not deviate during lifting and maintain a stable lifting trajectory.

[0034] Drive unit: The scissor lifting mechanism 4 is driven by a drive unit 7. The drive unit 7 includes a mounting plate 71 mounted on the frame 1, and an electro-hydraulic cylinder 72 is mounted on the side of the mounting plate 71. The piston end of the electro-hydraulic cylinder 72 is rotatably connected to the drive shaft 46 located below. Through the operation of the electro-hydraulic cylinder 72, the drive shaft 46 is driven to rotate, thereby driving the scissor lifting mechanism 4 to lift. The control system of the electro-hydraulic cylinder 72 can precisely control the lifting height through an electronic control device to ensure the accuracy of the operation.

[0035] Mecanum Wheel System: This transport vehicle uses Mecanum wheels as its drive system. Mecanum wheels allow the transport vehicle to move freely in any direction, avoiding the limitations of traditional transport vehicles that require complex steering. During operation, by controlling the rotation angle and speed of the Mecanum wheels, the transport vehicle can move flexibly in confined spaces, meeting the operational needs of special environments. The four Mecanum wheels are mounted at the four corners of the chassis, ensuring stable movement of the transport vehicle during lifting and lowering.

[0036] Lifting Operation and Control: The lifting operation of the transport vehicle is driven by an electric hydraulic cylinder 72 and adjusted by a control system. During the lifting process, the operator inputs lifting commands through the control panel, and the control system automatically adjusts the operation of the electric hydraulic cylinder 72 to precisely control the lifting height of the support plate 3. The lifting process is smooth and highly precise, adapting to the handling needs of items of different heights.

[0037] The working principle of this device is as follows:

[0038] During operation, when lifting is required, the control system activates the electro-hydraulic cylinder 72, whose piston pushes the drive shaft 46 to rotate. Through the cooperation of the rotating shaft 42 and the transmission arm 43, the pulley 45 rotates, causing the scissor lifting mechanism 4 to rise and fall along a set trajectory. The support plate 3 remains stable throughout the lifting process, without shifting or swaying. Thanks to the use of Mecanum wheel technology, the transport vehicle can not only rise and fall vertically but also move freely in all directions horizontally, greatly improving operational flexibility and efficiency.

[0039] This AGV transport vehicle is particularly suitable for environments with limited space and requiring precise operation, such as warehouses, logistics centers, and production workshops. Due to its omnidirectional mobility and high-precision lifting capabilities, this transport vehicle can complete tasks such as material handling and lifting in complex environments, significantly improving work efficiency.

[0040] In summary, the liftable platform transport vehicle based on Mecanum wheel omnidirectional movement technology provided in this embodiment combines the stability of a lifting platform with omnidirectional movement technology, exhibiting strong adaptability and flexibility. It can be widely applied in various scenarios, greatly improving operational efficiency and safety.

[0041] This embodiment provides only one specific implementation of the present invention, and other implementations and modifications should also be within the protection scope of the present invention. Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
