Description

Technical Field

[0001] The present invention relates to the technical field of vehicle maintenance, and in particular to a safety inflation protection device for tire maintenance. Background Art

[0002] Trucks are essential transport tools for cargo transportation. The safe and reliable inflation of their tires is directly related to the efficiency of transportation operations and the safety of personnel and equipment. However, the inflation process presents significant safety risks, primarily due to excessive air pressure or tire aging or damage, which can lead to explosions. Once an explosion occurs, the tire instantly releases enormous energy, generating a strong shock wave and splashing debris, posing a serious threat to surrounding personnel and equipment. This can not only cause casualties but also damage maintenance equipment, hindering the normal operation of maintenance work.

[0003] Currently, truck tire inflation is typically performed at repair stations, where the equipment often uses a frame structure to secure the tires to prevent them from flying in the event of an explosion. However, this frame structure has significant limitations in practical application. While it can somewhat limit the physical splash of the tires, it cannot effectively block the shock wave and energy release generated by the explosion. The shock wave can propagate outward through gaps in the frame, causing secondary damage to surrounding personnel and equipment, thereby increasing safety risks during the repair process.

[0004] Furthermore, truck tires gradually degrade during daily transportation due to complex road conditions and heavy loads. Therefore, all tires must be inflated during maintenance to ensure safety and reliability. However, existing frame-based maintenance equipment only supports single-tire inflation. This one-by-one operation significantly reduces maintenance efficiency, prolongs vehicle downtime, and negatively impacts the overall efficiency and economic benefits of logistics and transportation. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following advantages: In the technical solution provided by the present invention, the sealing strip 1 is driven to wrap around the tire for one circle by the mounting ring and the connecting piece, the tire is wrapped by the sealing strip 1, and the potential energy generated when the tire explodes is absorbed by the connecting piece and the sealing strip 1, thereby preventing the potential energy generated when the tire explodes from impacting objects around the truck. Furthermore, the sealing strip 1 wrapped around the tire is supported by the top block, thereby preventing the potential energy generated after the tire explosion from separating the connecting piece from the mounting ring, causing the sealing strip 1 to detach from the tire, so that the sealing strip 1 can only twist when the connecting piece is separated from the mounting ring, continuously absorbing the potential energy after the tire explosion, and reducing the impact of the potential energy after the tire explosion on surrounding objects.

[0017] The present invention wraps the truck tire by installing a ring, a connecting piece and a sealing strip, which can prevent the potential energy of the explosion when the truck tire is inflated from spreading outward, thereby protecting the safety of the objects. At the same time, the present invention only requires the truck to be driven to the maintenance equipment, and the tire is sealed and wrapped by installing a ring, a connecting piece and a sealing strip. Compared with the existing maintenance equipment, the present invention does not require the removal of the tire, and can inflate multiple tires for protection at the same time, thereby shortening the maintenance time of the truck tire and improving the maintenance efficiency.

[0018] The first and second blocking strips provided in the present invention can wrap the two tires on the same bearing, preventing the potential energy after the tire explosion from spreading and causing impact on surrounding objects. At the same time, holes are opened in the elastic cloth of the present invention to allow the gas generated after the explosion to leak out, preventing the gas after the explosion from being wrapped inside the first blocking strip, causing the elastic cloth to be ruptured by the gas.

[0019] The connecting piece designed in the present invention is wrapped around the outside of the tire, which can further absorb the potential energy of the explosion and improve the absorption effect of the potential energy. At the same time, the magnets on the connecting piece that attract each other will also absorb part of the potential energy, further reducing the diffusion of the potential energy after the tire explosion and improving the protection effect.

[0020] The soil on the installation groove and the elastic membrane is cleaned by a scraper to prevent soil accumulation from affecting the reuse of the sealing strip and the connecting piece, thereby reducing the maintenance cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] It also includes a top block 302 and an electric telescopic pressure rod 307; a plurality of electric telescopic pressure rods 307 are provided on the mounting plate 1; the output end of each electric telescopic pressure rod 307 is provided with a top block 302; and an arc surface is provided on the top block 302.

[0037] It also includes an elastic cloth 401 and a second blocking strip 41; a second blocking strip 41 is provided on the mounting plate 1, and a top block 302 is also provided on the second blocking strip 41; a third mounting groove 1003 is opened on the mounting plate 1; the second blocking strip 41 is located in the third mounting groove 1003; the second blocking strip 41 and the first blocking strip 4 are connected by the elastic cloth 401; the first blocking strip 4 is located in the first mounting groove 1001.

[0038] The elastic cloth 401 is provided with holes to allow the gas generated after the explosion to leak out, thereby preventing the gas after the explosion from being wrapped inside the sealing strip 1 4 and causing the elastic cloth 401 to be broken by the gas.

[0039] It also includes a water bag 3; the water bag 3 is arranged on the mounting ring 2.

[0040] A magnet is provided on the connecting piece 5 near the connecting plate 102, and a magnet is also provided on the mounting ring 2. The magnets on the mounting ring 2 and the connecting piece 5 attract each other, which is convenient for fixing the connecting piece 5 and facilitating the card block 105 to be sequentially inserted into the card slot 5001 on the adjacent connecting piece 5.

[0041] The working process of this safety inflation protection device for tire maintenance is as follows:

[0042] Hereinafter, a safety inflatable protective device for tire maintenance is referred to as maintenance equipment;

[0043] The workers first place the maintenance equipment in the following order: Figure 10 The driver then starts the truck to Figure 10 The perspective shown is a reference. After the truck's tires are aligned with adjacent mounting rings 2, the truck is moved from right to left, and the truck's tires contact the rightmost connecting piece 5 of each maintenance device. At this time, the annular slide 106 is controlled to drive the mounting ring 2 to rotate synchronously with the tire, while the first electric slide 101 drives the connecting plate 102 to move synchronously to the left with the tire. Simultaneously, as the mounting ring 2 rotates, the clamping block 105 sequentially engages with the adjacent connecting piece 5, which in turn drives the connecting piece 5 to wind through the mounting ring 2. Furthermore, the connecting piece 5 drives the sealing strip 4 to wind and wrap around the outside of the tire. When the tire explodes due to inflation, the resulting impact force acts on the connecting piece 5 and the sealing strip 4, preventing the tire from causing damage to surrounding objects.

[0044] When the impact force generated by the tire explosion is large, since the connecting piece 5 and the mounting ring 2 are connected by the clamping block 105, the impact force may cause the connecting piece 5 to separate from the mounting ring 2, and the sealing strip 4 is fixedly connected to the mounting plate 1, so that when the connecting piece 5 is separated from the mounting ring 2, the connecting piece 5 as a whole is in a blooming shape. At this time, the connecting piece 5 will drive the sealing strip 4 to twist, thereby absorbing energy and reducing damage to surrounding objects.

[0045] It should be noted that after the blocking strip 4 is wound around the tire for one circle, the electric telescopic pressure rod 307 drives the top block 302 to move to the right, so that the top block 302 is against the left side of the tire, thereby preventing the impact force generated after the explosion from causing the blocking strip 4 to separate from the tire. In addition, the top block 302 is in an arc shape close to the tire side, which can better fit the tire and fix the blocking strip 4.

[0046] The potential energy generated after the tire explodes will be absorbed by the blocking strip 4, and the top block 302 designed in the present invention can resist the blocking strip 4 wrapped around the upper tire, so as to prevent the connecting piece 5 from separating from the mounting ring 2 after absorbing the potential energy of the explosion after the tire explodes, causing the blocking strip 4 to directly separate from the tire and be unable to absorb the potential energy of the tire explosion, causing the potential energy to spread and cause damage to objects around the truck. Therefore, the blocking strip 4 is fixed by the top block 302. When the connecting piece 5 is separated from the mounting ring 2, the blocking strip 4 is still fixed on the tire. At this time, the blocking strip 4 can only twist to absorb the potential energy of the tire explosion, thereby reducing the impact of the potential energy after the tire explosion on surrounding objects.

[0047] As the mounting ring 2 rotates with the tire, the mounting ring 2 may cause wear to the wheel hub. To avoid wear to the wheel hub, the present invention designs a water bag 3. The water bag 3 is pre-filled with water. The water bag 3 prevents the mounting ring 2 from directly contacting the wheel hub and causing wear to the wheel hub. At the same time, the water bag 3 can also absorb part of the potential energy when the tire explodes, further reducing the impact of the tire explosion on objects around the truck.

[0048] According to the above workflow, we can know that the present invention has the following effects:

[0049] The mounting ring 2 and the connecting piece 5 drive the blocking strip 4 to wrap around the tire for one round, and the blocking strip 4 wraps the tire. The connecting piece 5 and the blocking strip 4 absorb the potential energy generated when the tire explodes, thereby preventing the potential energy generated when the tire explodes from impacting objects around the truck. Furthermore, the top block 302 supports the blocking strip 4 wrapped around the tire, thereby preventing the potential energy generated after the tire explosion from separating the connecting piece 5 from the mounting ring 2, causing the blocking strip 4 to detach from the tire. The blocking strip 4 can only twist when the connecting piece 5 is separated from the mounting ring 2, thereby continuously absorbing the potential energy after the tire explosion and reducing the impact of the potential energy after the tire explosion on surrounding objects.

[0050] The present invention wraps the truck tire by installing the ring 2, the connecting piece 5 and the sealing strip 4, so as to prevent the potential energy of the explosion when the truck tire is inflated from spreading outward, thereby protecting the safety of the items. At the same time, the present invention only requires the truck to be driven to the maintenance equipment, and the mounting ring 2, the connecting piece 5 and the sealing strip 4 are larger than the tire for sealing and wrapping. Compared with the existing maintenance equipment, the present invention does not require the removal of the tire, and can inflate multiple tires for protection at the same time, thereby shortening the maintenance time of the truck tire and improving the maintenance efficiency.

[0051] The existing truck rear wheel has two tires on the same shaft. When the maintenance equipment processes the two tires on the same shaft, the present invention adopts the following method: Figure 9In the arrangement shown, the blocking strip 1 4 is wound along the tire by the above method. At this time, the space between the two tires will be blocked by the blocking strip 1 4. The blocking strip 1 4 and the blocking strip 2 41 provided in the present invention can wrap the two tires on the same bearing, thereby preventing the potential energy after the tire explosion from spreading and causing impact on surrounding objects. At the same time, the elastic cloth 401 of the present invention is provided with holes to allow the gas generated after the explosion to leak out, thereby preventing the gas after the explosion from being wrapped inside the blocking strip 1 4, causing the elastic cloth 401 to be ruptured by the gas.

[0052] It should be noted that the widths of the connecting piece 5 and the elastic cloth 401 designed in the present invention are both greater than the width of the tire.

[0053] The connecting piece 5 designed in the present invention is wrapped around the outside of the tire, which can further absorb the potential energy of the explosion and improve the absorption effect of the potential energy. At the same time, the magnets on the connecting piece 5 that attract each other will also absorb part of the potential energy, further reducing the diffusion of the potential energy after the tire explosion and improving the protection effect.

[0054] The additional technical effects of the present invention are as follows:

[0055] Among them, such as Figure 2 As shown, a guide strip is provided on the mounting plate 1 for guiding the vehicle to quickly align the blocking strip 1 4 and the blocking strip 2 41 on the maintenance equipment during driving.

[0056] Example 2

[0057] On the basis of Example 1, Figures 1-8 and Figure 10 As shown, it also includes a second slider 104, a winding box 201, a shielding cloth 202 and a pressure plate 203; the second slider 104 is slidably connected to the first electric slide rail 101; the second slider 104 is provided with a pressure plate 203; the winding box 201 is provided on the mounting plate 1; the shielding cloth 202 is wound in the winding box 201, and the other end of the shielding cloth 202 is connected to the pressure plate 203; the shielding cloth 202 is located between the winding box 201 and the connecting plate 102.

[0058] An elastic membrane 204 is also included; an elastic membrane 204 is provided in each second mounting slot 1002 .

[0059] It also includes a second electric slide rail 301, a third slider 303, an electric push rod 304, a scraper 305 and a motor 306; the third slider 303 is slidably connected to the second electric slide rail 301; the third slider 303 is provided with an electric push rod 304; the output end of the electric push rod 304 is provided with a motor 306; the output end of the motor 306 is provided with a scraper bar; and a number of scrapers 305 are provided on the scraper bar.

[0060] The upper surface of the connecting piece 5 is arc-shaped to fit the annular surface of the mounting ring 2 , making it easier for the clamping block 105 to be clamped into the clamping groove 5001 .

[0061] During use, the present invention generally needs to be placed outdoors. To protect the equipment from prolonged exposure to the sun, the present invention is designed with a reel box 201 and a shielding cloth 202. When the equipment is not in use for maintenance, the second slider 104 drives the shielding cloth 202 and the pressure plate 203 to move rightward, unfolding the shielding cloth 202 to shield the connecting piece 5 and the blocking strip 4, protecting the equipment from exposure to the sun and extending the service life of the equipment. When the equipment needs to be used for maintenance, the second slider 104 drives the shielding cloth 202 and the pressure plate 203 to move leftward, and the shielding cloth 202 can be retracted.

[0062] Furthermore, during truck driving, dirt can adhere to the tires. During the process of securing the mounting ring 2 and the blocking strip 1 4 , there's a risk that dirt from the tires could fall into the second mounting groove 1002 . To prevent dirt from entering the second mounting groove 1002 , the present invention incorporates an elastic membrane 204 . As the connecting piece 5 moves upward with the mounting ring 2, the elastic membrane 204 follows the connecting piece 5 and blocks the second mounting groove 1002 , effectively preventing dirt from entering the second mounting groove 1002 . To prevent excessive dirt accumulation on the elastic membrane 204 and potentially affecting subsequent use of the maintenance equipment, the present invention incorporates a scraper 305 . Each mounting groove 1001 is provided with a scraper 305 , connected to each other by a scraper strip. Initially, the scraper 305 is located to the right of the mounting ring 2 , with its underside contacting the upper side of the mounting plate 1 . After the wheel passes over scraper 305, it continues to move leftward, driven synchronously by third slider 303. When the wheel stops moving, scraper 305 contacts the right side of the tire. The electric push rod 304 then drives scraper 305 and the scraping strip upward, moving the strip away from the surface of mounting plate 1. Motor 306 then rotates scraper 305 90 degrees, bringing it into a vertical position. At this point, scraper 305 on mounting groove 1001 contacts the bottom of mounting groove 1001, and the scraping strip on elastic membrane 204 contacts the elastic membrane 204. Next, third slider 303 drives scraper 305 from left to right, clearing dirt from mounting groove 1001 and on elastic membrane 204. This prevents dirt from accumulating on mounting groove 1001 and elastic membrane 204, which could affect the reuse of blocking strip 14 and connecting piece 5.

[0063] When the tires are fully inflated, the driver starts the truck and moves it from left to right, exiting the maintenance equipment.

[0064] According to the above working principle, we know that the present invention has the following effects:

[0065] The scraper 305 is used to clean the dirt on the installation groove 1001 and the elastic membrane 204 to prevent the accumulation of dirt from affecting the reuse of the sealing strip 4 and the connecting piece 5, thereby reducing the maintenance cost of the equipment.

[0066] On the basis of the above technical effects, the present invention also has the following advantages: the mounting groove 1001 on the mounting plate 1 of the present invention is a through groove, which facilitates the scraper 305 to directly scrape the soil in the mounting groove 1001 away from the mounting plate 1.

[0067] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
