AI Technical Summary
During the transportation process of AGV transfer vehicles, especially at turns, the goods on the loading platform are prone to shifting due to braking, resulting in displacement or falling. In particular, the loading platform of roller AGV transfer vehicles is a moving part and the contact area between the goods and the platform is small. Long-term transportation may cause the goods to shift or fall.
The design employs a combination of dampers and return springs. The dampers absorb the energy during braking, while the return springs partially reset the load during the stroke, reducing cargo movement. Simultaneously, three balance wheels are installed to evenly distribute the tension of the drive chain, reducing sprocket damage. Furthermore, a return push rod assists in pushing the return block, ensuring the stability of the mounting frame.
It effectively reduces the distance goods travel during braking, lowers the risk of goods shifting and falling, extends the service life of the drive chain, and improves transportation stability.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 1-3 This utility model discloses a roller-type AGV transfer vehicle, including a vehicle body 1. The upper end of the vehicle body 1 is provided with a placement plane. A mounting frame 2 is slidably mounted on the upper end of the vehicle body 1. Several rollers 3 are linearly arranged in the mounting frame 2. The placement plane is provided with a mounting groove 11. A damper 41 is installed in the mounting groove 11. The two ends of the damper 41 are respectively connected to the mounting frame 2 and the vehicle body 1. A return spring 42 is sleeved on the outside of the damper 41. The vehicle also includes a drive component 5, which includes a drive motor 51, a drive chain 52, and a sprocket 53. The drive motor 51 is fixedly installed in the vehicle body 1. The sprocket 53 is respectively installed at the output end of the drive motor 51 and one of the rollers 3. A balance component 61 is slidably mounted in the vehicle body 1. A balance wheel 62 is rotatably mounted on the balance component 61. The drive chain 52 passes around the balance wheel 62. A balance spring 63 is installed between the balance component 61 and the vehicle body 1.
[0036] Specifically, a mounting frame 2 that can slide in the forward direction is provided at the upper end of the placement plane. The roller 3 is mounted on the mounting frame 2, which serves as a cargo platform. A damper 41 and a return spring 42 are installed between the mounting frame 2 and the vehicle body 1. At least one of the rollers 3 is driven by a chain driven by a drive component 5. A balance wheel 62 is provided at the position of the drive chain 52, and the balance wheel 62 can slide through the balance spring 63.
[0037] In this way, by setting up the damper 41 and the return spring 42, when the vehicle body 1 brakes, the cargo and the mounting frame 2 move forward as a whole. The damper 41 absorbs part of the forward movement energy, and in the subsequent stroke, the return spring 42 partially resets the mounting frame 2, and the damper 41 absorbs part of the forward movement energy, thus reducing the distance the cargo moves.
[0038] In some feasible configurations, the vehicle body 1 is a commonly used AGV transfer platform, which will not be elaborated upon here. The mounting frame 2 is a rectangular frame, with the rollers 3 rotatably mounted at both ends within it. The upper end of the vehicle body 1 is a bolt-connected U-shaped plate, with a mounting groove 11 formed in the U-shaped plate. One end of the damper 41 is fixed to the end face of the mounting groove 11. A rectangular block is fixedly mounted on the mounting frame 2, and the other end of the damper 41 is fixed to the rectangular block of the mounting frame 2. The rectangular block ensures that the axial direction of the damper 41 is parallel to the forward direction. A return spring 42 is sleeved on the outside of the damper 41, with one end fixed to the damper 41 or the U-shaped plate, and the other end fixed to the rectangular block of the mounting frame 2. After the damper 41 is compressed or stretched, the return spring 42 gradually resets the damper 41. For ease of use, multiple mounting grooves 11, dampers 41, and return springs 42 are provided.
[0039] The drive motor 51 is installed inside the vehicle body 1. The balance component 61 is a rectangular plate. A T-shaped groove is provided on the side wall of the vehicle body 1. The rectangular plate is installed in the T-shaped groove. The balance wheel 62 is an H-shaped wheel. The drive chain 52 passes around the balance wheel 62. When the mounting frame 2 moves, the drive chain 52 moves synchronously and drives the balance wheel 62 to move, reducing the possibility of the drive chain 52 being pulled and damaged by sudden movement.
[0040] As one specific embodiment of the roller-type AGV transfer vehicle provided in the application, please refer to Figure 2 and Figure 4 There are two symmetrically arranged balance components 61, and each balance component 61 is equipped with three balance wheels 62. The drive chain 52 passes around the three balance wheels 62 in sequence.
[0041] Overall, by setting three balance wheels 62, when the mounting frame 2 moves back and forth, the tension of the drive chain 52 can be applied to one of the balance wheels 62, pulling the balance wheel 62 and further reducing the damage to the drive chain 52 caused by the tension of the two sprockets 53.
[0042] Further, please refer to Figure 4 Under normal conditions, the balance wheel 62 ensures that the wrap angle of the sprocket 53 is less than 180 degrees.
[0043] It should be understood that by setting the wrap angle of sprocket 53 to be less than 180 degrees, the wrap angle of drive chain 52 can meet the needs of drive sprocket 53 when it is under tension.
[0044] As another specific embodiment of the roller-type AGV transfer vehicle provided in the application, please refer to Figure 3 Each end of the roller 3 is provided with a sprocket 53, and adjacent sprockets 53 are connected by a chain.
[0045] Depending on the specific application scenario, the ends of adjacent rollers 3 are connected by a chain and connected to the roller 3 of the connecting drive component 5, which increases the integrity of roller 3 and reduces the possibility of roller 3 rolling along with the goods when they move forward due to inertia.
[0046] As one specific embodiment of the roller-type AGV transfer vehicle provided in the application, please refer to Figure 2 and Figure 6 A reset push rod 71 is installed in the mounting slot 11, and a reset block 72 is fixedly installed in the mounting bracket 2. The reset block 72 is located in the mounting slot 11, and the output end of the reset push rod 71 is directly opposite the reset block 72.
[0047] It should be understood that during the reset process via the reset spring 42, there may be cases where the reset is not completed. The reset push rod 71 is used to assist in pushing the reset.
[0048] Furthermore, the reset block 72 has a clearance hole 73, and a sliding member 74 is slidably installed in the clearance hole 73. The output end of the reset push rod 71 is fixedly connected to the sliding member 74.
[0049] It should be understood that by setting the clearance hole 73, the possibility of impact or pulling on the reset push rod 71 when the mounting bracket 2 moves is reduced.
[0050] In some feasible embodiments, the reset push rod 71 can be an electric push rod or a cylinder, the reset block 72 is a rectangular block, and the sliding member 74 is a U-shaped ring that passes through the clearance hole 73 and is fitted onto the reset block 72. To facilitate control of the reset distance, a distance sensor 75 is installed at one end of the mounting groove 11, and the distance sensor 75 is directly opposite the sliding member 74.
[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
