Description

Technical Field

[0001] This utility model relates to the field of shock absorption device technology, and in particular to a shock absorption device for non-shock-absorbing transport vehicles. Background Technology

[0002] Shock-free transfer vehicles are convenient, flexible, safe, durable, low-cost to purchase and maintain, and are frequently used in factories. They have a high load-bearing capacity and can lift items from low to high places for stacking and loading / unloading operations, or enable labor-saving and rapid movement of items.

[0003] Existing technologies often have the following drawbacks: When operators use transfer vehicles to move items, they usually need to stand on the operating pedals of the transfer vehicle. When the transfer vehicle travels over uneven ground, the impact force of the vehicle's movement is often directly transmitted to the operator, causing injury to the operator.

[0004] Therefore, this utility model provides a shock-absorbing device for non-shock-absorbing transport vehicles. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, when transport vehicles travel over uneven ground, the impact force generated during the vehicle's journey is often directly transmitted to the operator, causing injury to the operator. Therefore, this invention proposes a shock-absorbing device for a non-shock-absorbing transport vehicle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shock-absorbing device for a non-shock-absorbing transport vehicle, including a pedal, fifteen shock-absorbing springs fixedly connected to the upper surface of the pedal, a patterned plate fixedly connected to the other end of the fifteen shock-absorbing springs, four guide rods fixedly connected to the lower surface of the patterned plate, and guide cylinders fitted onto the surfaces of the four guide rods, with the guide cylinders fixedly connected to the pedal.

[0007] The effect achieved by the above components is that by setting shock-absorbing springs and patterned plates, shock absorption can be achieved when the operator stands on the pedal, thereby minimizing the risk of injury to the operator caused by the shaking of the transport vehicle.

[0008] Preferably, the guide tube has two limiting grooves on its side, and each of the upper limiting grooves of the guide tube is slidably connected to a limiting block, which is fixedly connected to the guide rod.

[0009] The effect achieved by the above components is as follows: by setting the limiting groove, the limiting block and the guide cylinder can be easily connected; by setting the limiting groove and the guide cylinder, the movement of the guide rod can be guided.

[0010] Preferably, a U-shaped plate is fixedly connected to the upper surface of the patterned plate, and the cross-section of the U-shaped plate is U-shaped.

[0011] The effect achieved by the above-mentioned components is that by setting up the "U"-shaped plate, the stability of the operator's standing position can be improved when the operator is operating the transfer vehicle.

[0012] Preferably, a limiting plate is installed on the inner wall of the "U"-shaped plate.

[0013] The effect achieved by the above components is that by setting a limit plate, the "U"-shaped plate can be used to restrict the position of the operator.

[0014] Preferably, a torsion spring is fixedly connected to the side of the limiting plate, and the other end of the torsion spring is fixedly connected to the "U"-shaped plate.

[0015] The effect achieved by the above components is that, by setting a torsion spring, the limiting plate can be rotated while ensuring a stable connection between the limiting plate and the "U"-shaped plate.

[0016] Preferably, the side of the "U"-shaped plate has an installation groove, and the surface of the installation groove on the "U"-shaped plate is in close contact with the limiting plate.

[0017] The effect achieved by the above components is that by setting the mounting slot, the limiting plate can be easily installed, while ensuring that the limiting plate can rotate.

[0018] Preferably, a rotating rod is fixedly connected to the side of the limiting plate near the torsion spring, and the other end of the rotating rod is fixedly connected to the "U"-shaped plate.

[0019] The effect achieved by the above components is that by setting the rotating rod, the position of the torsion spring can be restricted, and the stability of the limit plate installation can be improved.

[0020] In summary:

[0021] In this invention, by setting shock-absorbing springs and patterned plates, the impact force caused by the bumps of the transport vehicle can be reduced as much as possible to minimize the damage to the operator's body. By setting guide cylinders, guide rods, and limiting blocks and limiting grooves, the movement of the patterned plates can be restricted, improving the stability of the operator's standing position. By setting "U"-shaped plates and limiting plates, the swaying of the operator when standing on the patterned plates can be avoided as much as possible, further improving the stability of the operator's standing position.

[0027] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a shock-absorbing device for a non-shock-absorbing transport vehicle, including a pedal 1. Fifteen shock-absorbing springs 2 are fixedly connected to the upper surface of the pedal 1. A patterned plate 3 is fixedly connected to the other end of each of the fifteen shock-absorbing springs 2. Four guide rods 5 are fixedly connected to the lower surface of the patterned plate 3. Each of the four guide rods 5 is fitted with a guide cylinder 4, which is fixedly connected to the pedal 1. By setting the shock-absorbing springs 2 and the patterned plate 3, a shock-absorbing effect can be achieved when the operator stands on the pedal 1, thereby minimizing the risk of injury to the operator due to the shaking of the transport vehicle.

[0028] The following is a detailed explanation of its overall setup and function.

[0029] Reference Figures 1-4 As shown in this embodiment: Two limiting grooves 7 are opened on the side of the guide cylinder 4. Limiting blocks 6 are slidably connected to the surfaces of the upper limiting grooves 7 on both guide cylinders 4. The limiting blocks 6 are fixedly connected to the guide rod 5. By setting the limiting grooves 7, the limiting blocks 6 can be easily connected to the guide cylinder 4. By setting the limiting grooves 7 and the guide cylinder 4, the movement of the guide rod 5 can be guided. A U-shaped plate 8 is fixedly connected to the upper surface of the patterned plate 3. The cross-section of the U-shaped plate 8 is U-shaped. By setting the U-shaped plate 8, the stability of the operator's standing position can be improved when the operator operates the transfer vehicle. A limiting plate 11 is installed on the inner wall of the U-shaped plate 8. By setting the limiting plate 11, the U-shaped plate 8 can assist the U-shaped plate 8 in restricting the operator's position.

[0030] A torsion spring 12 is fixedly connected to the side of the limiting plate 11, and the other end of the torsion spring 12 is fixedly connected to the "U"-shaped plate 8. By setting the torsion spring 12, a stable connection between the limiting plate 11 and the "U"-shaped plate 8 can be ensured while allowing the limiting plate 11 to rotate. An installation groove 9 is opened on the side of the "U"-shaped plate 8, and the surface of the installation groove 9 on the "U"-shaped plate 8 is tightly fitted with the limiting plate 11. The installation groove 9 facilitates the installation of the limiting plate 11 while ensuring its rotation. A rotating rod 10 is fixedly connected to the side of the limiting plate 11 near the torsion spring 12, and the other end of the rotating rod 10 is fixedly connected to the "U"-shaped plate 8. The rotating rod 10 restricts the position of the torsion spring 12 and improves the stability of the limiting plate 11 during installation.

[0031] Working principle: When the operator needs to operate the transfer vehicle, they first stand on the surface of the patterned plate 3, then rotate the limiting plate 11 so that it rotates on the surface of the mounting groove 9 on the "U"-shaped plate 8, causing the limiting plate 11 to rotate away from the patterned plate 3. The operator can then adjust their legs so that they are on the inside and outside of the "U"-shaped plate 8 respectively. Releasing the limiting plate 11, under the elastic force of the torsion spring 12, the limiting plate 11 drives the rotating rod 10 to rotate, causing the limiting plate 11 to rotate closer to the patterned plate 3. At this time, the limiting plate 11, in conjunction with the "U"-shaped plate 8, restricts the operator's position. When the transfer vehicle travels over uneven roads, due to the vehicle's bumps, the patterned plate 3 compresses the shock-absorbing spring 2, causing the patterned plate 3 to move closer to the pedal 1, thus protecting the transfer vehicle. The shock absorber absorbs the impact force, while the guide rod 5 slides on the inner wall of the guide cylinder 4 and the limiting block 6 slides on the surface of the limiting groove 7, thus limiting the position of the patterned plate 3 and minimizing the possibility of the patterned plate 3 shifting during the extension and contraction of the shock absorber spring 2. By setting the shock absorber spring 2 and the patterned plate 3, the impact force caused by the bumps of the transport vehicle can be reduced as much as possible to minimize the damage to the operator's body. By setting the guide cylinder 4, guide rod 5, limiting block 6 and limiting groove 7, the movement of the patterned plate 3 can be limited, improving the stability of the operator's standing position. By setting the "U" shaped plate 8 and limiting plate 11, the swaying of the operator when standing on the patterned plate 3 can be minimized, improving the stability of the operator's standing position.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
