Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to a groove for measuring the depth of tread patterns on a smooth tire in wells to improve the problem of tread breakage and chipping. Background Technology

[0002] In the design and application of special tires for underground mining, the presence of tread depth grooves is not only a necessary configuration required by regulations, but also a key factor affecting tire lifespan due to the extreme working conditions underground.

[0003] Although the slick tires used in wells have a "slick" tread pattern as their core tread shape, they still need to strictly follow the relevant regulations for tire safety performance testing. Tread depth measurement is a core indicator for assessing the wear of tires and determining whether they meet the conditions for safe use. Therefore, a tread structure that can be used for measurement must be retained on the tread, namely tread depth measuring grooves.

[0004] From a design perspective, these sounding grooves are not evenly distributed across the entire tread, but rather concentrated in the tire shoulder. This is because the tire shoulder is the transition area between the tread and the sidewall. Compared to the center of the tread (the main area of ​​stress and friction during underground operations), the shoulder experiences less direct wear, allowing it to retain the original shape of the sounding grooves more stably and for a longer period, ensuring accurate tread depth measurement throughout its entire lifespan. Simultaneously, the shoulder has relatively ample space, so the sounding grooves do not excessively occupy the effective contact area at the center of the tread, avoiding any impact on the tire's load-bearing and grip performance.

[0005] Designing 2-3 tread depth gauges on one side is the optimal choice after balancing "measurement accuracy" and "structural stability." If the number is too small (e.g., only one), uneven wear in certain areas may lead to measurement errors, failing to reflect the overall wear condition of the tire. If the number is too large (e.g., four or more), it will fragment the overall structure of the tire shoulder, weakening its impact and deformation resistance, thus increasing the risk of early damage. In addition, the depth and width of the tread depth gauges must be matched with industry-standard measuring tools (such as tire tread depth gauges). The depth is usually slightly greater than the legal wear limit of underground tires (the wear limit of underground engineering tires is generally 2-3mm, and the initial depth of the tread depth gauges is often designed to be 5-8mm) to ensure that the tread depth gauges remain measurable until the tire reaches the scrap standard.

[0006] The underground working environment is a harsh test for tires. The surface is often wet, and large pieces of ore severely cut the tires, directly accelerating tire wear. Due to the extreme working conditions underground, the tread depth grooves become the weakest link in the tire's tread, most prone to failure. Sharp ore often penetrates the tread depth grooves, cutting them and causing chipping and breakage, leading to premature tire failure.

[0007] Premature failure of smooth tread tires in well operations due to tread depth gauge groove cutting not only shortens tire life and increases equipment maintenance costs, but also may affect the efficiency of well operations due to frequent tire replacements. Therefore, it is necessary to redesign a tread depth gauge groove that can improve the problem of tread chipping and breakage. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tread depth gauge groove for underground smooth tires that improves the problem of tread breakage and chipping caused by sharp ore inserting into the tread depth gauge groove and cutting it. This effectively reduces the problem of early tire failure caused by the cutting and chipping of the tread depth gauge groove.

[0009] The technical solution of this utility model is as follows: The well-drilled smooth tire tread depth gauge groove improves the problem of tread chipping and breakage. The tread depth gauge groove is located at the tire shoulder. A reinforcing rib is provided on the outer side of the tread depth gauge groove to the lower part of the shoulder. There is a height difference between the upper end face of the reinforcing rib and the outer contour line of the tire. This height difference forms an indicator groove. The reinforcing rib is inclined towards one side of the tread depth gauge groove, so that the tread depth gauge groove has a flared shape that is wider at the top and narrower at the bottom.

[0010] Preferably, a plurality of stone-throwing devices are provided on the side of the reinforcing rib facing the patterned depth measuring groove.

[0011] Preferably, the stone-throwing device is elongated.

[0012] Preferably, the height of the stone-throwing device is 5-10 mm.

[0013] Preferably, the height difference between the upper end face of the reinforcing rib and the outer contour line of the tire is 10-30mm.

[0014] Preferably, the sidewalls and bottom of the patterned depth sounding groove are designed with rounded corners.

[0015] Compared with the prior art, this utility model has the following advantages: 1. From passively enduring to actively protecting, significantly reducing the risk of pieces breaking off when breaking flowers. Traditional smooth-surface tread depth sounding grooves in mines serve only as a measurement structure required by regulations, lacking specific protective designs. When faced with ore embedding, they can only passively withstand damage. In contrast, this utility model constructs an active protection system through a combination design of "reinforcing ribs + flared opening + stone ejector + rounded corners": reinforcing ribs enhance the strength of the edge structure, reducing chipping from the perspective of "damage resistance"; the flared opening shape, in conjunction with the stone ejector, reduces embedding from the perspective of "ore interception"; and the rounded corner design disperses pressure, reducing cracks from the perspective of reducing the degree of damage. This multi-dimensional synergy reduces the incidence of chipping and breakage at the tread depth sounding groove, solving the core pain point of traditional structures being easily cut and failed by ore.

[0016] 2. Achieve a balance between retaining functionality and optimizing performance, while also considering regulatory and practical needs. While improving the problem of tread depth loss, this utility model does not sacrifice the core function of the tread depth measuring groove (tread depth measurement). Instead, it enhances practicality through detailed design: the indicator groove can quickly locate the tread depth measuring groove, avoiding low measurement efficiency caused by the smooth tread surface; the rounded corners and the size design of the stone dropper are designed to provide sufficient measurement space, ensuring that the industry-standard tread depth gauge can be smoothly inserted into the bottom of the groove, fully complying with the relevant regulations for measurement accuracy.

[0017] In summary, the design of the tread depth groove of this utility model can effectively improve the problem of sharp minerals inserting into the tread depth groove and cutting it, thus reducing the problem of early tire failure caused by the cutting and breaking of the tread depth groove.

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0022] Example 1 Existing structural designs for patterned depth sounding grooves, such as Figure 1 As shown, sharp minerals often penetrate these tread depth grooves, cutting into them and causing chipping and breakage, ultimately leading to premature tire failure. To address this issue, such as... Figure 2As shown, this embodiment provides a tread depth measuring groove for a smooth tread tire to improve the problem of tread breakage and chipping. The tread depth measuring groove 1 is located at the tire shoulder 2. A reinforcing rib 3 is provided on the outer side of the tread depth measuring groove 1 (the side away from the center of the tread) to the lower part of the shoulder. By increasing the rubber thickness at the edge of the tread depth measuring groove 1, the impact and tear resistance of the edge is improved, and the rigidity of the edge of the tread depth measuring groove 1 is strengthened, preventing tread breakage and chipping caused by the insertion and cutting of ore. There is a height difference of 10-30mm between the upper end face of the reinforcing rib 3 and the outer contour line of the tire. This height difference forms an indicating groove 4, which can serve as a "positioning mark" for tread depth measurement, guiding the operator to quickly find the position of the tread depth measuring groove 1 and avoiding measurement deviations caused by the smoothness of the tire tread.

[0023] like Figure 2 As shown, the reinforcing rib 3 is inclined towards one side of the patterned depth sounding groove 1, forming an inclined wall surface, making the patterned depth sounding groove 1 a funnel shape that is wider at the top and narrower at the bottom. This shape can change the embedding path of the ore: when a sharp ore moves towards the patterned depth sounding groove 1 as the tire rolls, the inclined wall surface will guide the ore, making it easier for the ore to slide out of the groove along the wall surface, rather than directly embedding vertically into the bottom of the groove, thus reducing problems such as stones getting stuck in the patterned depth sounding groove 1 from the source.

[0024] Example 2 Based on Example 1, such as Figure 2 As shown, several long strip-shaped stone-slingers 5 with a height of 5-10mm are provided on the side of the reinforcing rib 3 facing the patterned depth sounding groove 1. When the ore hits the stone-slinger 5, the stone-slinger 5 can convert the impact force into elastic potential energy through slight deformation, thereby ejecting the ore away from the patterned depth sounding groove 1. This can improve the effect of preventing stones from getting stuck in the patterned depth sounding groove 1 and play the role of ejecting the ore before it enters the bottom of the groove to protect the bottom of the groove.

[0025] Example 3 Based on Example 1, the sidewall of the patterned depth sounding groove 1 is designed with rounded corners between the groove and the bottom. Compared with the traditional right-angle connection structure, this design can eliminate the sharp stress points at the bottom of the groove. When the ore is embedded, the rounded corners can disperse the local pressure of the ore on the bottom of the groove, prevent the sharp edges of the ore from directly penetrating the rubber at the bottom of the groove, reduce the generation of cracks at the bottom of the groove, and play a role in protecting the bottom of the groove.
