[0001] The utility model relates to the technical field of transportation equipment, and particularly relates to a heavy-duty polyurethane wheel with a shock-absorbing mechanism. Background Art

[0002] The polyurethane wheel is made of polyurethane, which is polymerized from isocyanate and hydroxyl compounds. It has good oil resistance, toughness, wear resistance, aging resistance and adhesiveness. The polyurethane wheel has excellent sound absorption characteristics and is usually used as a caster material.

[0003] The Chinese utility model patent with the publication number CN218616092U proposes a high-speed heavy-duty polyurethane wheel with good shock-absorbing effect, including a fixing plate. On both sides of the lower end of the fixing plate, support plates are symmetrically connected. A polyurethane wheel body is rotatably connected between the two support plates through a rotating shaft. An I-shaped seat is embedded at the upper end of the fixing plate, and the I-shaped seat is rotatably connected to the fixing plate. An installation plate is fixedly connected to the upper end of the I-shaped seat, and a shock-absorbing component is installed on the upper end of the installation plate.

[0004] The above device absorbs and alleviates vibration energy by setting a shock-absorbing component to protect the equipment from the influence of excessive vibration. However, when the equipment itself is heavy, especially under high-speed heavy-duty working conditions, the huge impact force and continuous pressure may not only cause the shock-absorbing component to wear and fail too quickly, but also directly damage the roller. Therefore, we propose a heavy-duty polyurethane wheel with a shock-absorbing mechanism to solve the above problems. Summary of the Invention

[0025] This application provides a heavy-duty polyurethane wheel with a shock-absorbing mechanism, mainly used to solve the problem in the prior art that when the equipment itself is heavy, especially under high-speed heavy-duty working conditions, the huge impact force and continuous pressure may not only cause excessive wear and failure of the shock-absorbing assembly, but also directly cause damage to the roller, and provides the following technical solutions, which will be described in detail below in conjunction with Figures 1 - 4 Make a detailed description:

[0026] A heavy-duty polyurethane wheel with a shock-absorbing mechanism includes:

[0027] A mounting base 1, the mounting base 1 is a hollow structure, and a circular through-hole 101 is formed in the middle of the top of the mounting base 1;

[0028] A universal wheel 2, the universal wheel 2 is installed in the middle of the bottom of the mounting base 1;

[0029] A support assembly 3, used to assist in supporting mechanical equipment, the support assembly 3 includes extension plates 305 fixedly arranged at the bottom of the four sides of the mounting base 1, a support tube 301 is fixedly arranged at the bottom of the extension plate 305, and a ball eye wheel 302 is installed at the bottom of the support tube 301;

[0030] A shock-absorbing assembly 4, arranged inside the mounting base 1, and the shock-absorbing assembly 4 is used to absorb and isolate the vibration generated by mechanical equipment.

[0031] Description of the working process:

[0032] During use, according to the body size specifications of the equipment, select an appropriate number of this device and install it at the bottom of the mechanical equipment. Among them, the universal wheel 2 is installed in the middle of the bottom of the mounting seat 1 to provide the equipment with flexible mobility. At the same time, a support assembly 3 is provided. The extension plate 305 and the support tube 301 together form a stable support structure that can bear the weight of the mechanical equipment and provide the necessary support force. The bull's-eye wheel 302 serves as a support point and can roll on the ground, enabling the equipment to move easily. The significance of setting the support assembly 3 is that it can share the pressure borne by the universal wheel 2 and prevent the universal wheel 2 from being damaged due to the overweight of the equipment. In addition, the shock-absorbing assembly 4 is provided. When the mechanical equipment is running, the shock-absorbing assembly 4 can effectively absorb and isolate the vibration generated by the mechanical equipment, protecting the equipment from the influence of excessive vibration.

[0033] It should be noted that the equipment installed with this device generally moves and travels in a factory environment with good road conditions.

[0034] As Figure 4 shown, in some embodiments, a connecting plate 303 is fixedly provided between the bottom and top of the extension plate 305 and the side wall of the mounting seat 1. The connecting plate 303 is trapezoidal. More specifically, the connecting plate 303 is located between the bottom and top of the extension plate 305 and the side wall of the mounting seat 1, playing a role of connection and reinforcement, which helps to enhance the overall firmness of the device.

[0035] As Figure 4 shown, in some embodiments, a screw 304 is fixedly provided at the top of the bull's-eye wheel 302. The screw 304 is in threaded connection with the support tube 301. More specifically, the bull's-eye wheel 302 is a small rotary bearing, usually made of wear-resistant materials, which can roll on various surfaces, reduce friction and provide smooth movement. In this device, the bull's-eye wheel 302 is installed at the bottom of the support tube 301 as the moving fulcrum of the equipment. The threaded connection design simplifies the installation process. Just screw the screw 304 into the support tube 301 to complete the installation. At the same time, if the bull's-eye wheel 302 needs to be replaced or repaired, it can also be easily disassembled and reinstalled.

[0036] As Figure 4As shown, in some embodiments, the shock absorption assembly 4 includes guide rods 401 fixedly arranged at intervals between the bottom inner walls of the mounting base 1. Slide plates 402 are slidably sleeved on both sides of the surface of the guide rods 401. A spring 403 is sleeved in the middle of the guide rods 401. A damping shock absorber 404 is installed between one side of the slide plate 402 away from the spring 403 and the inner wall of the mounting base 1. Hinge plates 405 are hinged to both sides of the top of the slide plate 402. A movable plate 406 is slidably arranged on the upper side inside the mounting base 1. One end of the hinge plate 405 away from the slide plate 402 is hinged to the bottom of the movable plate 406. A connecting rod 407 is connected to the middle of the top of the slide plate 402. The connecting rod 407 slidably penetrates inside the circular through hole 101. More specifically, when the equipment operates, the vibration and impact force generated are transmitted to the connecting rod 407 through the mechanical equipment, and then transmitted from the connecting rod 407 to the slide plate 402. When the slide plate 402 is vibrated, the spring 403 absorbs the energy of the vibration through its own deformation and converts it into elastic potential energy. The damping shock absorber 404 can convert the elastic potential energy of the spring 403 into heat energy. These processes together reduce the vibration energy transmitted to the equipment, thus playing a role in shock absorption and buffering and providing better protection for the equipment.

[0037] As Figure 4 shown, in some embodiments, a disc spring 408 is slidably sleeved on the surface of the connecting rod 407. More specifically, the disc spring 408 has non-linear characteristics and can generate different deformation amounts when subjected to forces of different magnitudes. This characteristic makes the disc spring 408 highly efficient in the field of shock absorption, capable of better absorbing and isolating vibration energy and reducing the vibration transmitted to the equipment. When the vibration and impact force generated during the operation of the equipment are transmitted to the connecting rod 407 through the mechanical equipment and then from the connecting rod 407 to the disc spring 408, due to the non-linear characteristics of the disc spring 408, it can automatically adjust the deformation amount according to the magnitude and direction of the vibration, thus better absorbing and isolating the vibration energy.

[0038] As Figure 1 shown, in some embodiments, a mounting plate 5 is fixedly arranged at the top of the connecting rod 407. Mounting holes 501 are formed at the four corners of the mounting plate 5. More specifically, by fixing the mounting plate 5 to the bottom of the equipment, a tight connection between the mechanical equipment and the shock absorption assembly 4 can be achieved. This connection method not only ensures the stability of the mechanical equipment but also improves the shock absorption effect. Mounting holes 501 are formed at the four corners of the mounting plate 5, and the mounting plate 5 can be firmly connected to the bottom of the mechanical equipment through bolts or other fasteners, and can maintain a stable connection state even when subjected to large vibrations or impacts.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
