[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. Based on the embodiments in the implementation manners, it is intended to explain the present invention and should not be construed as a limitation to the present invention.

[0042] As used herein, the phrase "one embodiment" or "example" or "instance" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0043] As a first aspect of the present invention, there is provided a material transport vehicle, as Figure 1As shown, the material transport vehicle includes a vehicle body 200 and a cantilever shaft 300. The cantilever shaft 300 protrudes from the front side plate 210 of the vehicle body 200. Among them, a receiving cavity is formed inside the vehicle body 200. It should be noted that the forward direction of the material transport vehicle is the front, and the side plate of the vehicle body 200 facing the front is the front side plate.

[0044] In an embodiment of the present invention, the material transport vehicle may further include a leveling assembly 400, a first pusher assembly 500, a second pusher assembly 600, and a pusher plate 700.

[0045] As Figure 2 shown, the front side plate 210 of the vehicle body 200 includes a front side plate main body 211 and a cantilever shaft mounting plate 212. A cantilever mounting opening is formed on the front side plate main body 212. The cantilever shaft mounting plate 212 is hinged at the top edge of the cantilever mounting opening. The cantilever shaft 300 is mounted on the cantilever shaft mounting plate 212. The leveling assembly 400 is disposed in the receiving cavity, and the leveling assembly 400 is used to drive the cantilever shaft mounting plate 212 to rotate around the hinge. It should be noted that the top edge of the cantilever mounting opening is the edge of the cantilever mounting opening facing away from the mobile chassis.

[0046] The first pusher assembly 500 can drive the second pusher assembly 600 to move along the cantilever shaft 300. The pusher plate 700 is connected to the second pusher assembly 600, and the second pusher assembly can drive the pusher plate 700 to move along the cantilever shaft 300.

[0047] When the material transport vehicle transports coiled or cylindrical materials, the materials are sleeved on the cantilever shaft 300. Under the action of the gravity of the materials, it may tilt downward, causing the cantilever shaft 300 to no longer be horizontal. In this case, the leveling assembly 400 is used to push the cantilever shaft mounting plate 212 to rotate around the hinge, so that the cantilever shaft 300 returns to the horizontal position again. The cantilever shaft 300 is in the horizontal position for docking with the docking device.

[0048] After the material transport vehicle reaches the unloading position, the first pusher assembly 500 can be used to push the second pusher assembly 600, and then the second pusher assembly 600 is used to drive the pusher plate 700 to push the materials to the docking device, rather than pushing the materials to the docking device at one time, which improves the stability of unloading.

[0049] The greater the complexity on the cantilever shaft 300, the easier it is for the cantilever shaft 300 to tilt. The leveling assembly 400 can be used to adjust the cantilever shaft back to the horizontal position again. That is to say, the material transport vehicle provided by the embodiment of the present invention is particularly suitable for transporting large-load materials.

[0050] In the embodiment of the present utility model, the material transport vehicle may further include a mobile chassis 100, and the vehicle body 200 is installed on the mobile chassis 100. By controlling the movement of the mobile chassis 100, the material transport vehicle can be moved to the required position.

[0051] As an alternative embodiment, the first pusher assembly 500 can drive the second pusher assembly 600 to move forward along the cantilever shaft 300 and can also drive the second pusher assembly 600 to move backward along the cantilever shaft 300. Similarly, the second pusher assembly 600 can drive the pusher plate 700 to move forward along the cantilever shaft 300 and can also drive the pusher plate 700 to move backward along the cantilever shaft 300.

[0052] In the embodiment of the present utility model, the cantilever shaft 300 is located in the accommodation cavity, thereby improving the compactness of the material transport vehicle.

[0053] In the embodiment of the present utility model, the specific structure of the first pusher assembly 500 is not particularly limited, as long as it can drive the second pusher assembly 600 to move along the cantilever shaft 300. As an alternative embodiment, the first pusher assembly 500 may include any one of a piston cylinder and a lead screw assembly. Optionally, in order to improve stability and increase the pusher stroke, as Figure 3 and Figure 4 shown, the first pusher assembly 500 includes a guide rack 510, a pusher gear 520, and a gear mounting bracket 530.

[0054] The pusher gear 520 is rotatably installed on the pusher assembly mounting bracket 530. The guide rack 510 is arranged on the cantilever shaft 300, and the length direction of the guide rack 510 is consistent with the length direction of the cantilever shaft 300. The pusher gear 520 meshes with the guide rack 510, and the gear mounting bracket 530 can move along the cantilever shaft 300 with the pusher gear 520. The second pusher assembly 600 is connected to the gear mounting bracket 530 to move along the cantilever shaft 300 with the gear mounting bracket 530.

[0055] The position of the guide rack 510 remains fixed. After driving the pusher gear 520 to rotate around its own axis, the pusher gear 520 can move along the guide rack 510 and drive the gear mounting bracket 530 and the second pusher assembly 600 to move along the guide rack 510. This "gear-rack" matching method is simple to install and has high stability, which is more conducive to pushing the material out of the cantilever shaft 300.

[0056] In order to further improve the stability of the pusher process, optionally, as Figure 5As shown, the first material pushing assembly 500 further includes a guiding frame 550 and at least one guiding rod 540. The guiding frame 550 is connected to the gear mounting frame 530 to move along with the gear mounting frame 530. A guiding hole corresponding to the guiding rod 540 is formed on the guiding frame 550. One end of the guiding rod 540 can pass through the cantilever shaft mounting plate 212 and enter the accommodation cavity, and the other end of the guiding rod 540 passes through the guiding hole and is connected to the material pushing plate 700.

[0057] As Figure 7 shown, a slider 551 is formed on the guiding frame 550, and a limiting guiding groove 310a matching the slider 551 is formed on the cantilever shaft 300. The limiting guiding groove 310a extends along the axial direction of the cantilever shaft 300. The slider 551 is arranged in the limiting guiding groove 310a and moves along the limiting guiding groove 310a.

[0058] When using the second material pushing assembly 600 to push the material pushing plate 700, the guiding rod 540 slides in the guiding hole, which can prevent the second material pushing assembly 600 from shaking and improve the stability of the material pushing process.

[0059] In Figure 2 and Figure 3 the shown embodiment, it can be seen that the first material pushing assembly 500 and the second coating assembly 600 overlap in length, occupying less space on the cantilever shaft 300 and improving the compactness of the structure of the material transport vehicle.

[0060] In the embodiment of the present utility model, no special limitation is imposed on the specific structure of the second material pushing assembly 600 either. For example, the second material pushing assembly 600 can be selected from a piston cylinder and a lead screw assembly.

[0061] As an alternative embodiment, as Figure 5 shown, the second material pushing assembly 600 includes a telescopic push rod 610 and a telescopic push rod driving mechanism 620. The telescopic direction of the telescopic push rod 610 is consistent with the length direction of the cantilever shaft 300. Correspondingly, the first material pushing assembly further includes a limiting frame 560, which is arranged on the guiding frame 550, and a push rod hole is formed on the limiting frame 560.

[0062] The output end of the telescopic push rod 610 passes through the push rod hole and is connected to the material pushing plate 700, and the material pushing plate 700 and the telescopic rod driving mechanism 620 are respectively located on both sides of the limiting frame 560.

[0063] The position of the limiting frame 560 is fixed, so that the material pushing plate 700, the telescopic push rod 610, and the guiding rod 540 form a stable triangular support structure, making the force on the pushing plate 700 more stable and having better stiffness, and capable of pushing the material farther from the cantilever shaft 300 of the current material transport vehicle.

[0064] The telescopic push rod 610 can be telescoped under the drive of the telescopic rod drive mechanism 620, thereby driving the pusher plate 700 to move.

[0065] The telescopic push rod 610 can be an electric push rod or a hydraulic push rod. When the telescopic push rod 610 is an electric push rod, the telescopic rod drive mechanism 620 is a motor; when the telescopic push rod 610 is a hydraulic push rod, the telescopic rod drive mechanism 620 is a hydraulic pump.

[0066] To facilitate the movement of the second pusher assembly 600, optionally, a through hole 212a is provided at a position on the cantilever shaft mounting plate 212 corresponding to the telescopic push rod drive mechanism 620, and the mounting seat of the telescopic push rod drive mechanism 620 can pass through the through hole 212a.

[0067] When the material is arranged on the cantilever shaft 300, the second pusher assembly 600 is relatively close to the cantilever shaft mounting plate 212. As the pushing progresses, the second pusher assembly 600 gradually moves away from the cantilever shaft mounting plate 212.

[0068] In the embodiment of the present utility model, both the first pusher assembly 500 and the second pusher assembly 600 have a certain pusher stroke, so as to increase the total pusher stroke and the pusher speed. Specifically, the total pusher stroke of the pusher plate 700 is the sum of the distance that the first pusher assembly 500 moves forward and the pushing distance of the second pusher assembly 600.

[0069] Relatively speaking, the pusher stroke of the second pusher assembly 600 is relatively short, and the material can be pushed to a set position on the cantilever shaft of the docking-side material transport vehicle.

[0070] In the embodiment of the present utility model, no special limitation is imposed on the specific structure of the pusher plate 700. To facilitate the smooth movement of the pusher plate 700, optionally, a gap is formed between the pusher plate 700 and the cantilever shaft 300. As Figure 6As shown, the pusher plate 700 includes a connecting lug 740, a first straight arm 710, a second straight arm 720, and an arc-shaped connecting piece 730. The arc-shaped connecting piece 730 connects one end of the first straight arm 710 and one end of the second straight arm 720. The first straight arm 710 and the second straight arm 720 are respectively located at the radial two ends of the cantilever shaft 300. The inner wall of the arc-shaped connecting piece 730 matches the outer surface of the cantilever shaft 300. The guiding holes are formed on both the first straight arm 710 and the second straight arm 720. The connecting lug 740 is arranged at one end of the first straight arm 710. The output end of the second pusher assembly 600 is fixedly connected to the connecting lug 740. Optionally, in order to facilitate the control of the leveling assembly, the material transport vehicle further includes a position sensor, which is arranged on the cantilever shaft to detect the angle of the cantilever shaft 300 relative to the horizontal direction. The position sensor is electrically connected to the control end of the leveling assembly so that the leveling assembly acts according to the signal of the position sensor.

[0071] When the angle between the cantilever shaft 300 and the horizontal direction exceeds a certain value, it can be determined that the cantilever shaft 300 is no longer horizontal, and the leveling assembly can be used to push the cantilever shaft mounting plate 212.

[0072] Optionally, in order to reduce the friction force received by the material when pushing the material and facilitate the pushing of the material, as Figure 2 shown, the cantilever shaft 300 includes a shaft body 310 and a roller 320. The shaft body 310 is fixed on the cantilever shaft mounting plate 212. A roller receiving groove is formed on the shaft body 310. The roller 320 is rotatably installed in the roller receiving groove, and a part of the roller 320 protrudes from the opening of the receiving groove. In this embodiment, a limit guiding groove 310a is formed on the shaft body 310 and extends along the length direction of the shaft body 310.

[0073] Optionally, in order to ensure that the material can be stably fixed on the cantilever shaft 300 during the material transfer process, as Figure 2 shown, the material transport vehicle further includes a clamping plate 800, which is arranged at one end of the cantilever shaft 300 away from the cantilever shaft mounting plate 212.

[0074] The clamping plate 800 is located at the end of the cantilever shaft 300. The clamping plate 800 can prevent the material from falling during the process of the cantilever shaft 300 transporting the material, playing a role of limiting. Moreover, the clamping plate 800 can also prevent the material from falling from the cantilever shaft 300 when the cantilever shaft 300 rotates.

[0075] In the embodiment of the present invention, no special limitation is made on the specific structure of the leveling assembly. Optionally, the leveling assembly includes a leveling rod and a leveling driving device. One end of the leveling rod is connected to the cantilever shaft mounting plate, and the leveling driving device is used to drive the leveling rod to move along the axis.

[0076] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
