Abstract
Description
Technical Field
[0001] The present invention relates to the field of tire inflation repair, and in particular to a rapid explosive inflation repair process for severely deflated and bead-detached tires, and is particularly suitable for bead resetting and airtightness recovery of large machinery tires. Background Art
[0002] In modern industry and engineering, large-scale machinery, such as construction machinery, mining equipment, and port machinery, is widely used. The large vacuum tires they use, as critical load-bearing components, endure high loads under complex operating conditions. These tires are prone to serious deflation, bead separation, and flattening due to punctures by sharp objects, bead aging, or improper operation. These tires feature high sidewall strength, thick bead wire, and a high overall mass. If the bead becomes separated from the wheel hub, traditional inflation repair processes present significant challenges.
[0003] Currently, deflation of ordinary vacuum tires can usually be restored by directly inflating them with an on-board air pump or an external air source. However, for tires that are severely debonded and flattened, especially those on large machinery, the tire bead is very rigid and has a wide contact area with the wheel hub. The fitting surface between the tire bead and the wheel hub edge forms a tight fit after deflation. The low-pressure gas from an ordinary air pump cannot overcome the frictional resistance and atmospheric pressure between the two in a short period of time, resulting in the tire bead being unable to be effectively reset and the airtightness being difficult to restore. Traditional solutions often require completely removing the tire from the wheel hub and transporting it to a professional repair site for resetting and inflation using large equipment. This process is not only time-consuming and labor-intensive, increasing labor and transportation costs, but also can delay project progress due to equipment downtime. This problem is particularly prominent in field operations, mining, and other remote scenarios without a fixed air source.
[0004] While existing technologies attempt to address the tire bead resetting problem through high-pressure air pumps or specialized inflation equipment, these pumps rely on a stable power supply or large air source, are bulky and difficult to move, and the continuous input of high-pressure gas can potentially damage the tire structure. In particular, there are technical bottlenecks in controlling transient pressure. For large machinery tires, their structural characteristics, which can withstand transient high temperatures and high pressures, have not been fully utilized. There is an urgent need for an efficient emergency repair process that leverages the tire's inherent structural advantages and does not require complex equipment. This can address industry pain points such as difficulty resetting and slow inflation caused by the tire's high bead rigidity and wide contact area, and achieve the goal of quickly restoring the tire's airtightness and performance.
[0005] The present invention is proposed based on the above-mentioned technical status quo and actual needs. By innovatively introducing the principle of explosive inflation, the peak air pressure generated at the moment of explosion of the flammable spray is used to drive the tire bead to quickly reset, forming a temporary seal, and creating conditions for subsequent air pump inflation. It effectively overcomes the technical defects of traditional processes in repairing serious tire debonding of large machinery, and significantly improves operational efficiency and emergency repair capabilities. Summary of the Invention
[0006] This invention discloses a rapid explosive emergency repair process for severely deflated, bead-destroying, and flattened tires. It is particularly suitable for emergency repair of vacuum tires on large machinery. This process overcomes the bottleneck of traditional inflation technology by utilizing the kinetic energy of gas expansion during the explosion to rapidly reposition and temporarily seal the tire bead, providing an innovative solution for efficient repairs in environments without a fixed air source.
[0007] The process implementation flow is as follows: First, clean the mud, oil and other debris on the contact edge of the wheel hub and the tire bead to ensure that the fitting surface is clean to improve the sealing effect; then use a portable pressure tank to evenly spray 5-15ml of flammable liquefied gas (such as brake disc cleaner, ether) into the original gap between the bead and the wheel hub, and the spray amount is precisely controlled according to the tire specifications; ignite the spray at a safe distance, and instantly explode to generate a peak air pressure of 5-8MPa (duration <0.1 second), and use the explosive impact force of the high-temperature and high-pressure gas to quickly push the bead into the groove on the edge of the wheel hub to form a temporary airtight seal; finally, use an ordinary air pump to inflate to normal tire pressure to complete the repair.
[0008] The core principle of this process lies in its deep integration with the structural characteristics of large machinery tires—the high-strength sidewall and thick bead wire can withstand instantaneous high pressure. The pulsed energy generated by the explosion directly acts on the bead unseating area, overcoming the rigid resistance of the bead and atmospheric pressure in the form of kinetic energy. This solves the problem of "wide contact area and high reset resistance" that traditional low-pressure air pumps cannot overcome. Compared to continuous high-pressure inflation, the instantaneous energy release during the explosion process avoids the tire from bearing continuous loads. The explosive force of the gas expansion achieves a rapid reset in milliseconds, creating the necessary conditions for subsequent regular inflation.
[0009] The device consists of a wheel hub, tire, flammable gas pressure tank, and ignition device. The original gap acts as an energy transfer channel for the explosive gas. The flammable spray vaporizes within the gap to form a combustible mixture, which is instantly converted into high-pressure gas upon ignition. This expansion force acts evenly along the circumference of the tire bead, ensuring stability and sealing during the reset process. This process requires less than 5 minutes per operation and does not require tire removal or large equipment. It is particularly suitable for use in mines, ports, field operations, and other locations without an external gas source, significantly reducing equipment downtime and transportation costs.
[0010] Compared to existing technologies, this invention's innovations lie in: 1) replacing sustained high pressure with explosive kinetic energy, overcoming the volume and air source limitations of traditional inflation equipment; 2) leveraging the tire's inherent structural strength to design an energy transfer method for precise and efficient tire bead repositioning; and 3) creating a combined "instantaneous sealing and rapid pressure replenishment" repair mechanism to address the challenge of emergency repair of debonded tires. This process combines both technological breakthroughs and engineering practicality, providing a safe and efficient new approach for rapid on-site repair of large machinery tires, with significant economic benefits and industry application value. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate the composition and operating principles of the device of the present invention in different states.
[0012] like Figure 1-3 As shown, Figure 1 A cross-sectional view of a tire during the process of the present invention when a flammable spray is sprayed after debris is cleared; Figure 2 This is a cross-sectional view of a tire in a gas explosion state after ignition spraying according to the process of the present invention; Figure 3 This is a cross-sectional view of the tire after the tire bead is pushed back into the hub slot after the gas explosion according to the process of the present invention.
[0013] The devices involved in the process mainly include: a wheel hub (1), a tire (2), an original gap (3) formed between the tire (2) and the wheel hub (1) after being flattened by being unhooked, a flammable gas pressure tank (4), a flammable spray (5), an ignition rod (6), and an explosive gas (7), wherein the structure of the tire (2) includes a tire bead (21) and a tire wall (22), and a wheel hub slot (11) is provided in the wheel hub (1).
[0014] like Figure 1 As shown, when the tire (2) is flattened after being unhooked, the tire bead (21) is separated from the wheel hub slot (11) and an original gap (3) is formed. During operation, debris at the contact edge between the wheel hub (1) and the tire (2) is first cleaned, and then a small amount of flammable spray (5) is evenly sprayed along the original gap (3) using a flammable gas pressure tank (4).
[0015] like Figure 2 As shown, at a certain safe distance from the tire (2), an ignition rod (6) is used to ignite the flammable spray (5) in the original gap (3), and then an explosive gas (7) is quickly generated in the tire (2).
[0016] like Figure 3 As shown, the instantaneous thermal expansion pressure of the ignited explosive gas (7) pushes the tire bead (21) back to the position of the hub slot (11), so that the tire bead (21) and the hub slot (11) are quickly engaged and reset, thereby restoring the temporary airtightness of the tire (2) and forming a temporary seal, while supporting the tire wall (22). DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0018] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology, and are not used to limit the conditions for implementation of the present invention. Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.
[0019] The core of the rapid explosion emergency repair process for a debonded tire provided by the present invention is to utilize the kinetic energy of gas expansion at the moment of explosion to achieve rapid resetting and temporary sealing of the tire bead of a large machinery tire. The process principle and device composition are closely integrated, as follows: For large machinery tires with severe deflation that causes the tire bead to come off and flatten, the repair process first requires cleaning the debris on the contact edge between the wheel hub (1) and the tire bead (21) to ensure that the contact surface between the two is clean, creating conditions for subsequent sealing and resetting.
[0020] like Figure 1 As shown, an irregular original gap (3) is formed between the tire (2) and the wheel hub (1) after the tire is unhooked. At this time, a small amount of flammable spray (5) is evenly sprayed into the original gap (3) through the flammable gas pressure tank (4). The flammable spray (5) is preferably a flammable liquefied gas with rapid vaporization characteristics such as brake disc cleaning agent and ether. The spray amount is controlled within an appropriate range according to the tire specifications, which can ensure that the explosion energy is sufficient to push the tire bead (21) back to its original position while avoiding excessive safety risks.
[0021] like Figure 2 As shown, after the spray is completed, the ignition rod (6) is used to ignite the flammable spray at a safe distance. The instantaneous intense combustion causes the gas volume to expand rapidly, forming high-temperature and high-pressure explosive gas (7). The 5-8MPa peak pressure generated at the moment of explosion acts on the tire bead (21) and the tire wall (22) in the form of a shock wave. The high-strength tire wall structure and thick tire bead wire bearing capacity unique to large machinery tires (2) are used to convert the instantaneous high pressure into kinetic energy that pushes the tire bead (21) back to its original position.
[0022] like Figure 3As shown, the energy release time of the explosive gas (7) is extremely short (less than 0.1 second). While preventing the tire (1) from being subjected to continuous high pressure, the instantaneous impact force breaks through the friction resistance between the tire bead (21) and the wheel hub (1), allowing the tire bead (21) to quickly fit into the wheel hub edge groove (11), restoring the fit between the two and forming a temporary airtight seal.
[0023] After the temporary seal is formed, the tire (2) must be inflated immediately using a conventional air pump until the tire pressure returns to normal. This design cleverly utilizes the explosion process to complete the "key step" of tire bead reset, and then uses conventional inflation equipment to complete the final tire pressure replenishment. This not only avoids the equipment dependence problem of traditional high-pressure air pumps, but also accurately solves the reset problem caused by the large rigidity and wide contact area of the tire bead through the explosion energy.
[0024] This process is particularly suitable for emergency situations such as field operations and mining operations. Relying on a portable flammable gas pressure tank and a simple ignition device, it can complete the entire repair process, from tire bead reset to tire pressure restoration, in just 5 minutes. Unlike traditional methods that require the tire to be disassembled and returned to the factory for repair, this method directly utilizes the tire's inherent ability to withstand instantaneous high pressure to convert the explosive energy into efficient mechanical reset force. This improves repair efficiency while significantly reducing equipment downtime and transportation costs, providing an innovative solution for the rapid on-site repair of large machinery tires. Example
[0025] Several large construction vehicles in a mining area, due to long-term parking, suffered air leaks, leading to bead debonding and complete tire flattening. Attempts to inflate the tires with a standard air pump failed due to significant friction caused by the long-term separation and deformation between the bead and the wheel hub, preventing the bead from returning to its original position. Traditional repair methods, requiring tire disassembly and specialized equipment, were not only time-consuming and labor-intensive, but also significantly impacted work progress.
[0026] Faced with this situation, the maintenance personnel adopted an explosive emergency repair process: first, remove the dust, rust and aged glue on the contact edge of the wheel hub and the tire rim to ensure the cleanness of the fitting surface and prepare for the subsequent seal reset; then use a portable pressure tank to evenly spray 10ml of ether-based flammable spray along the gap between the tire rim and the wheel hub, spraying once every 15cm to allow the spray to fully penetrate into the gap between the tires; then ignite the spray away from the tire, and instantly explode to produce high-pressure gas with a peak pressure of about 6MPa. The kinetic energy of the gas expansion pushes the tire rim to quickly fit into the wheel hub slot to form a temporary seal. The tire body is initially propped up, and no obvious leakage is found after testing with soapy water; finally, immediately connect the air pump to inflate. The tire pressure rises to the standard value within 2 minutes, and the tire resumes normal support performance. The average repair process for each tire takes no more than 5 minutes.
[0027] The core of this process is to harness the kinetic energy of the gas expansion during the explosion of the flammable spray, converting the instantaneous high pressure into force for the tire bead to reset, thereby overcoming the frictional resistance caused by long-term bead unseating and deformation. The high-strength sidewall and thick bead wire of large tires can withstand the instantaneous impact (lasting less than 0.1 second), while avoiding structural damage. The explosive impact force allows the tire bead to quickly engage, creating a seal for subsequent inflation.
[0028] Practice has proven that this method reduces the traditional repair time from several hours to just five minutes, significantly reducing equipment downtime losses. It also requires no external air source or large tools, making it suitable for use in parking lots, the field, and other locations without fixed repair conditions. Furthermore, the instantaneous energy release does not damage the tire structure, ensuring that the repaired tire meets airtightness standards and can be used directly. This combination of "explosive kinetic energy reset" and conventional inflation and pressure replenishment solves the tire bead adhesion problem caused by long-term storage with a low-cost, portable tool, providing an efficient and safe practical example for the rapid repair of similar bead-out tires.
