DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-11 , the present invention provides a loader tire for construction and mining, comprising a pressure-bearing component 1 and two protection components 2;

[0034] The pressure-bearing component 1 includes a tread 101 and an anti-puncture component 3. Both sides of the tread 101 are fixedly provided with shoulders 102. The inner walls of the two shoulders 102 are fixedly provided with sidewalls 103. The tread 101, the two shoulders 102 and the two sidewalls 103 are set as an integrated structure. A carcass steel wire layer 104 is fixedly provided between the two sidewalls 103.

[0035] Specifically, the tread 101 is the part of the tire that is most in contact with the road surface, the sidewall 103 of the tire has the function of supporting the tire and resisting shock, but it is also the weakest part of the tire surface, and the shoulder 102 is the part connecting the tread 101 and the sidewall 103, and can bear greater pressure when turning;

[0036] The two protection components 2 each include an annular seat 201 and a fixing component 4. The two annular seats 201 are fixedly arranged on both sides of the carcass steel wire layer 104, respectively. A plurality of first protrusions 202 are fixedly arranged on one side of the two annular seats 201. A second protrusion 203 is slidably connected between every two corresponding first protrusions 202. A protection ring 204 is fixedly arranged on one side of the plurality of second protrusions 203 on one side and on one side of the plurality of second protrusions 203 on the other side.

[0037] The two protective rings 204 and the two annular seats 201 are both made of aluminum alloy. The surfaces of the two protective rings 204 are provided with a plurality of ventilation grooves 205. The plurality of ventilation grooves 205 on one side and the plurality of ventilation grooves 205 on the other side are evenly distributed in an annular shape. The protective rings 204 and the annular seats 201 transfer the heat of the tire steel wire layer 104, which is beneficial to the heat dissipation of the tire. The ventilation grooves 205 increase the contact area between the air and the protective rings 204, thereby increasing the contact area between the airflow and the protective rings 204 when the loader is moving, thereby improving the heat dissipation effect.

[0038] The surfaces of the two annular seats 201 are fixedly connected to the inner walls of the two tire walls 103 respectively, and the contact parts of the two annular seats 201 and the plurality of second protrusions 203 are slidably connected, and the annular seats 201 are pressed against the second protrusions 203, so that the protective ring 204 is quickly installed;

[0039] Specifically, the sidewall 103 is covered by the protective ring 204. When a loader transports excavated soil or minerals, the gravel that is splashed laterally onto the tires of other loaders due to tire squeezing can be blocked by the protective ring 204, reducing the risk of tire blowout caused by the impact of gravel on the sidewall 103. When installing the protective ring 204, the protective ring 204 is moved, and the protective ring 204 drives the second protrusion 203 to move, causing the second protrusion 203 to be inserted into the interior of two adjacent first protrusions 202 until the second protrusion 203 is supported by the annular seat 201, thereby completing the positioning of the protective ring 204, which is very convenient. Several first protrusions 202 and several second protrusions 203 cooperate to form a circular ring to limit the protective ring 204 on the vertical plane.

[0040] The puncture-proof component 3 includes a cloth curtain layer 301, which is fixedly arranged on the surface of the carcass steel wire layer 104, and the contact parts of the cloth curtain layer 301 and the two sidewalls 103 are fixedly connected, and a steel wire belt layer 302 is fixedly arranged on the surface of the cloth curtain layer 301, and the cloth curtain layer 301 is made of puncture-proof fabric;

[0041] A polyester cap layer 303 is fixedly disposed on the surface of the steel band layer 302. The surface of the polyester cap layer 303 is fixed to the inner wall of the tread 101. The polyester cap layer 303 can fix the steel band layer 302 to prevent it from being seriously deviated.

[0042] Specifically, the fabric layer 301 can improve the compressive strength of the tire and prevent the tread 101 of the tire from being punctured when subjected to a violent impact, which is beneficial to maintaining the standard air pressure inside the tire and improving reliability.

[0043] The two fixing components 4 each include a mounting groove 401, a baffle 407 and a consolidation component 5. The two mounting grooves 401 are respectively opened on the surfaces of the two first protrusions 202. The inner walls of the two mounting grooves 401 are fixedly provided with a box body 402. The inner walls of the two box bodies 402 are slidably connected with a slide plate 403. A first spring 404 is fixedly provided between the two slide plates 403 and the corresponding box body 402. The backs of the two slide plates 403 are fixedly provided with a fixing rod 405 and a pressing block 406. One of the baffles 407 is fixedly provided at one end of one of the protective rings 204, and the other baffle 407 is fixedly provided at one end of the other protective ring 204. The surfaces of the two baffles 407 are provided with fixing holes 408 and guide grooves 409. The inner walls at the bottom ends of the two guide grooves 409 are provided with auxiliary holes.

[0044] The inner walls of the two fixing holes 408 are respectively slidably connected to the surfaces of the two fixing rods 405, and the inner walls of the two guide grooves 409 are respectively slidably connected to the surfaces of the two pressing blocks 406. The fixing rods 405 can slide into the fixing holes 408, thereby abutting against the baffle 407, and completing the fixing of the protective ring 204.

[0045] The surfaces of the two boxes 402 are provided with sliding holes 410 and sliding grooves 411. The surfaces of the two sliding holes 410 are respectively slidably connected to the surfaces of the two fixed rods 405. The inner walls of the two sliding grooves 411 are respectively slidably connected to the surfaces of the two pressing blocks 406. The inner walls of the two boxes 402 are fixedly provided with guide rods 412. The two guide rods 412 respectively penetrate the surfaces of the two slide plates 403. The two guide rods 412 are respectively placed inside the two first springs 404. The fixed rods 405 are retracted into the sliding holes 410 to prevent the fixed rods 405 from hindering the longitudinal movement of the baffle 407, so as to facilitate the removal of the protective ring 204. The slide plate 403 can slide along the surfaces of the guide rods 412. The stability of the slide plate 403 during movement is improved by the guide rods 412. At the same time, the guide rods 412 limit the bending amplitude of the first spring 404 to prevent the first spring 404 from being greatly distorted during the rotation of the tire, thereby extending the service life of the first spring 404.

[0046] Specifically, when installing the protective ring 204, the pressure block 406 is pushed, and the pressure block 406 will push the slide plate 403 to move. The slide plate 403 compresses the first spring 404, and the slide plate 403 drives the fixing rod 405 to move, prompting the fixing rod 405 to retract into the interior of the sliding hole 410, and then the protective ring 204 is moved, and the protective ring 204 drives the baffle 407 to move, prompting the guide groove 409 of the baffle 407 to slide longitudinally along the surface of the pressure block 406 until the second protrusion 203 at one end of the protective ring 204 is supported by the annular seat 201. At this time, the fixing hole 408 on the surface of the baffle 407 will be aligned with the sliding hole 410, and the pressure block 406 is released. The first spring 404 extends and pushes the slide plate 403 and the fixing rod 405 to move, prompting the fixing rod 405 to be stuck in the fixing hole 408, thereby completing the fixation of the baffle 407 and the protective ring 204. There is no need to use bolts when fixing the protective ring 204, which is very convenient.

[0047] The two consolidation components 5 each include an auxiliary groove 501 and a limiting hole 502. The two auxiliary grooves 501 are respectively provided on the surfaces of the two baffles 407. The inner walls of the two auxiliary grooves 501 are slidably connected with U-shaped plates 503. A second spring 504 is fixedly provided between the two U-shaped plates 503 and the corresponding auxiliary grooves 501. A limiting rod 505 is fixedly provided at the bottom end of the two U-shaped plates 503. The two limiting holes 502 are respectively provided on the surfaces of the two pressing blocks 406. The inner walls of the two limiting holes 502 are slidably connected with the surfaces of the two limiting rods 505.

[0048] The backs of the two U-shaped plates 503 are fixed with booster blocks 506. The surfaces of the two U-shaped plates 503 are slidably connected with the surfaces of the two boxes 402 respectively. The surfaces of the booster blocks 506 are provided with arc surfaces. Use your fingers to press against the arc surfaces and push the booster blocks 506 upwards. The U-shaped plates 503 are driven to move upwards by the booster blocks 506, so that the U-shaped plates 503 can be adjusted conveniently.

[0049] Specifically, before pushing the pressing block 406, the boosting block 506 is pushed, and the boosting block 506 drives the U-shaped plate 503 to move upward, and the U-shaped plate 503 compresses the second spring 504, and the U-shaped plate 503 drives the limiting rod 505 to move upward, so that the limiting rod 505 is separated from the limiting hole 502, and the limiting hole 502 is released by the limiting rod 505. Then, the pressing block 406 is pressed into the interior of the box body 402 to install the protective ring 204. After installing the protective ring 204, the limiting rod 505 is aligned with the limiting hole 502, and the second spring 504 will extend and push the U-shaped plate 503 and the limiting rod 505 to move downward, causing the limiting rod 505 to pass through the limiting hole 502 and get stuck in the auxiliary hole. At this time, the limiting rod 505 will resist the pressure block 406 to fix the pressure block 406, thereby improving the stability of the pressure block 406, the slide plate 403, the fixing rod 405 and the protective ring 204.

[0050] When in use, the sidewall 103 is covered by the protective ring 204. When a loader transports excavated soil or minerals, the gravel splashed laterally to the tires of other loaders due to tire squeezing will be blocked by the protective ring 204, reducing the risk of tire blowout caused by the impact of gravel on the sidewall 103, making it safer. The protective ring 204 and the annular seat 201 will transfer the heat of the carcass steel wire layer 104, which is beneficial to the heat dissipation of the tire. The ventilation groove 205 increases the contact area between the airflow and the protective ring 204 when the loader is moving, thereby improving the heat dissipation effect.

[0051] When the protective ring 204 needs to be installed, the pressing block 406 is pushed, and the pressing block 406 pushes the slide plate 403 to move. The slide plate 403 compresses the first spring 404, and the slide plate 403 drives the fixing rod 405 to move, causing the fixing rod 405 to retract into the interior of the sliding hole 410. Then the protective ring 204 is moved, and the protective ring 204 drives the second protrusion 203 to move, causing the second protrusion 203 to be stuck into the interior of the two adjacent first protrusions 202, until the second protrusion 203 is resisted by the annular seat 201, completing the positioning of the protective ring 204, and at the same time, the moving protective ring 204 will drive the baffle 407 to move, causing the guide groove 409 of the baffle 407 to slide longitudinally along the surface of the pressing block 406 until the second protrusion 203 is abutted by the annular seat 201. At this time, the fixing hole 408 on the surface of the baffle 407 will be aligned with the sliding hole 410, and then the pressing block 406 is released, and the first spring 404 extends and pushes the slide plate 403 and the fixing rod 405 to move, causing the fixing rod 405 to snap into the fixing hole 408, thereby completing the fixing of the baffle 407 and the protective ring 204. It is not necessary to use bolts when fixing the protective ring 204, which is very convenient.

[0052] After installing the protective ring 204, the limiting rod 505 is aligned with the limiting hole 502, and the second spring 504 will extend and push the U-shaped plate 503 and the limiting rod 505 to move downward, causing the limiting rod 505 to pass through the limiting hole 502 and get stuck in the auxiliary hole. At this time, the limiting rod 505 will resist the pressure block 406 to fix the pressure block 406, thereby improving the stability of the pressure block 406, the slide plate 403, the fixing rod 405 and the protective ring 204.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
