Description

Technical Field

[0001] This utility model relates to the field of wheel technology, and in particular to a self-adjusting wheel device. Background Technology

[0002] In modern transportation and various mobile equipment fields, the performance of wheel assembly plays a crucial role in the overall operation of the equipment.

[0003] Traditional wheel systems have drawbacks when dealing with complex road conditions. For example, on uneven surfaces, the wheels struggle to adaptively adjust their contact with the ground. Conventional wheels are rigidly connected to the equipment chassis, so when encountering potholes or uneven surfaces, the impact is directly transmitted to the equipment, potentially damaging internal components and shortening its lifespan. In outdoor work vehicles frequently traveling on rugged construction sites, the inability of the wheels to effectively cushion vibrations significantly increases the failure rate of the equipment inside the vehicle. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a self-adjusting wheel device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-adjusting wheel device, comprising a chassis and a wheel body, wherein a sliding column is slidably connected inside the chassis, a connecting block is fixedly installed at the top of the sliding column, a U-shaped frame is fixedly installed at the bottom of the sliding column, an adaptive spring is sleeved on the outer wall of the sliding column, and an L-plate is fixedly installed on one side of the U-shaped frame.

[0006] Preferably, the wheel body is rotatably connected to the U-shaped frame.

[0007] Preferably, the top end of the adaptive spring is fixedly connected to the chassis, and the bottom end of the adaptive spring is fixedly connected to the U-shaped frame.

[0008] Preferably, the L-plate is internally threaded with a threaded rod, and a scraper is rotatably connected to one end of the threaded rod near the wheel body. Limiting rods are symmetrically fixedly installed on the side of the scraper near the threaded rod, and a throttle is fixedly installed on the other end of the threaded rod away from the scraper.

[0009] Preferably, the limiting rod is slidably connected to the L-plate.

[0010] Preferably, an anti-detachment block is fixedly installed at the end of the limiting rod away from the scraper block.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting a sliding column, a U-shaped frame, and an adaptive spring between the wheel body and the chassis, when the equipment carried by the device encounters potholes or bumps on a bumpy road, the adaptive spring can compress or stretch according to the magnitude of the impact force. When the wheel body encounters a bump, it absorbs part of the impact force and reduces the vibration transmitted to the chassis of the equipment. When the wheel body sinks into a pothole, it helps it to quickly return to a suitable position to maintain good contact with the ground. This not only improves the driving stability of the vehicle, but also reduces the damage of the impact force to the internal components of the equipment, effectively solving the problems existing in traditional wheel devices.

[0013] 2. In this utility model, by rotating the throttle to drive the threaded rod to rotate, the scraper can be conveniently and efficiently pushed closer to or away from the wheel body to clean the mud, sand and other debris on the surface of the wheel body, greatly saving cleaning time and labor costs. The stable structure between the scraper and the L-plate, consisting of a limiting rod and an anti-detachment block, prevents the scraper from rotating or falling off during movement, ensuring a stable and reliable cleaning process. After cleaning, the scraper is returned to its initial position, which not only prevents the scraper from accidentally colliding with the wheel body and damaging the wheel body, but also protects the scraper itself, extends its service life, and reduces replacement costs.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figures 1-2 As shown, this utility model provides a technical solution: a self-adjusting wheel device, including a chassis 1 and a wheel body 2. A sliding column 3 is slidably connected inside the chassis 1. A connecting block 4 is fixedly installed at the top of the sliding column 3. A U-shaped frame 5 is fixedly installed at the bottom of the sliding column 3. An adaptive spring 6 is sleeved on the outer wall of the sliding column 3. An L-plate 7 is fixedly installed on one side of the U-shaped frame 5. The wheel body 2 is rotatably connected to the U-shaped frame 5. The top of the adaptive spring 6 is fixedly connected to the chassis 1, and the bottom of the adaptive spring 6 is fixedly connected to the U-shaped frame 5.

[0021] In this embodiment, by setting a sliding column 3, a U-shaped frame 5, and an adaptive spring 6 between the wheel body 2 and the chassis 1, when the equipment mounted on the device encounters potholes or bumps on a bumpy road, the adaptive spring 6 can compress or stretch according to the magnitude of the impact force. When the wheel body 2 encounters a bump, it absorbs part of the impact force and reduces the vibration transmitted to the equipment chassis 1. When the wheel body 2 sinks into a pothole, it helps it to quickly return to a suitable position to maintain good contact with the ground. This not only improves the vehicle's driving stability but also reduces the damage of the impact force to the internal components of the equipment, effectively solving the problems existing in traditional wheel devices.

[0022] Example 2: As Figures 2-3 As shown, the L plate 7 has a threaded rod 8 internally connected to it. The end of the threaded rod 8 near the wheel body 2 is rotatably connected to a scraper 9. A limit rod 10 is symmetrically fixedly installed on the side of the scraper 9 near the threaded rod 8. A throttle 12 is fixedly installed on the end of the threaded rod 8 away from the scraper 9. The limit rod 10 is slidably connected to the L plate 7. An anti-detachment block 11 is fixedly installed on the end of the limit rod 10 away from the scraper 9.

[0023] In this embodiment, by rotating the throttle 12 to drive the threaded rod 8 to rotate, the scraper 9 can be conveniently and efficiently pushed closer to or away from the wheel body 2 to clean the mud, sand and other debris on the surface of the wheel body 2, greatly saving cleaning time and labor costs. The stable structure between the scraper 9 and the L plate 7, consisting of the limiting rod 10 and the anti-detachment block 11, prevents the scraper 9 from rotating or falling off during movement, ensuring a stable and reliable cleaning process. After cleaning, the scraper 9 is returned to its initial position, which can not only prevent the scraper 9 from accidentally colliding with the wheel body 2 and damaging the wheel body 2, but also protect the scraper 9 itself, extend its service life, and reduce replacement costs.

[0024] The working principle of this embodiment is as follows: When the equipment carried by the device travels on a bumpy road, such as when it encounters potholes or bumps, the wheel body 2 will be impacted first. Since the wheel body 2 is rotatably connected to the U-shaped frame 5, and the U-shaped frame 5 is slidably connected to the chassis 1 through the sliding column 3, and the outer wall of the sliding column 3 is fitted with an adaptive spring 6, the top end of the adaptive spring 6 is fixed to the chassis 1, and the bottom end is fixed to the U-shaped frame 5. At this time, the U-shaped frame 5 will move up and down with the impact force on the wheel body 2, causing the sliding column 3 to slide inside the chassis 1. The adaptive spring 6 plays a key role in this process. It will compress or stretch according to the magnitude of the impact force. When the wheel body 2 encounters a bump and is pushed upward, the adaptive spring 6 is compressed, absorbing part of the impact force and reducing the vibration transmitted to the equipment chassis 1. When the wheel body 2 sinks into a pothole, the adaptive spring 6 stretches, helping the wheel body 2 to quickly return to a suitable position and always maintain a good contact state with the ground, thereby reducing the damage of the impact force to the internal components of the equipment. After the wheel body 2 has been used for a period of time, dirt, sand, and other debris will accumulate on its surface, requiring cleaning. At this time, the operator can turn the handle 12. Since the threaded rod 8 is threadedly connected to the L plate 7, the rotation of the handle 12 will drive the threaded rod 8 to rotate. During the rotation, the threaded rod 8 will move linearly along the threaded hole of the L plate 7, thereby pushing the scraper 9 closer to or away from the wheel body 2. A limit rod 10 is symmetrically fixed on one side of the scraper 9. The limit rod 10 is slidably connected to the L plate 7, and an anti-detachment block 11 is installed at the end away from the scraper 9. This structure ensures that the scraper 9 can only move along the axial direction of the threaded rod 8. To prevent the scraper block 9 from rotating or falling off during movement, when the scraper block 9 moves to contact the surface of the wheel body 2, the device can be pushed to move the wheel body 2. As the wheel body 2 rolls, the scraper block 9 begins to perform its cleaning function, scraping off the mud, sand and other debris attached to the surface of the wheel body 2 little by little. After cleaning, the operator turns the handle 12 in the opposite direction, and the threaded rod 8 rotates in the opposite direction, causing the scraper block 9 to gradually move away from the wheel body 2 and return to its initial storage position. This not only prevents the scraper block 9 from accidentally colliding with the wheel body 2 during vehicle operation, but also protects the scraper block 9 itself and extends its service life.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
