Description

Technical Field

[0001] This utility model belongs to the technical field of port and terminal lifting equipment, and more specifically, it relates to a tire for a tire-mounted container crane. Background Technology

[0002] In the existing technology, the traveling mechanism of the rubber-tired container crane in the container terminal is equipped with 8 pneumatic bias tires. The rubber-tired container crane is supported by these pneumatic bias tires, and the movement of the entire equipment is achieved by driving the tires. Since the self-weight of the rubber-tired container crane reaches 140 tons and the rated lifting weight is 41 tons, the pneumatic bias tires need to be of size 21.00-25, and the inflation pressure needs to reach 1MPa to meet the normal movement of the entire equipment. However, during the use of pneumatic bias tires, technicians need to regularly check the tire pressure to ensure it is sufficient. When the tire pressure is insufficient, the tire needs to be inflated. During the tire inflation process, technicians face certain risks of human-machine interaction and are susceptible to injury from the machinery. Furthermore, pneumatic bias tires can explode during use, affecting the balance and stability of the entire equipment and posing a safety hazard. Moreover, bias tires are prone to leaks and cracking, especially tires that are only 1-2 years old or have good tread patterns, requiring replacement and resulting in significant waste and increased maintenance costs.

[0003] Therefore, this utility model provides a tire for a tire-mounted container crane. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a tire for a tire-type container crane, which fills an inflatable bias tire with a high elasticity and strong ballast resistance material, making it a solid tire and achieving the effect of a solid tire, aiming to solve one of the problems existing in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] A tire for a tire-mounted container crane, which is an inflatable bias-ply tire, is characterized in that the tire is filled with a filler to make it a solid tire, the filler being a mixture of granules and a polymer material AB glue that has been solidified and cured.

[0007] The tire used in a tire-mounted container crane is characterized in that the granules are waste tire particles processed and cut from waste tires, and the shape and size of the waste tire particles are 2CM*2CM*2CM.

[0008] The tire for a tire-mounted container crane is characterized in that the proportion of waste tire particles used to fill the tire is 35%-40% of the tire's internal volume.

[0009] The tire for a tire-mounted container crane is characterized in that it has several vent holes drilled in its circumferential direction, which are used to expel gas from the tire when filling it with filler.

[0010] The tire for a tire-mounted container crane is characterized in that the vent holes are drilled in the tread grooves of the tire, and the distance between two adjacent vent holes is three tread grooves.

[0011] The tire used in a tire-mounted container crane is characterized in that, after the air is expelled from the tire through the vent hole, it is secured with stainless steel flat-head self-tapping screws.

[0012] In summary, compared with the prior art, due to this structure, the pneumatic bias tire is filled with a filler made of a mixture of granules and AB polymer material, which is then solidified and hardened, thus making it a solid tire and achieving the performance of a solid tire. Therefore, the beneficial effects of this utility model are:

[0013] 1. There is no need to check tire pressure or regularly inflate tires, which saves manpower and avoids the unsafe factors of human-machine cross-operation.

[0014] 2. Replaced tires are cut into waste tire pellets and used as filler material for reuse, which avoids waste of resources and reduces equipment maintenance and production costs.

[0015] 3. When pneumatic bias tires are filled into solid tires, their wear resistance and service life are improved. At the same time, tire explosion will not occur, which improves the stability of the entire equipment and avoids the occurrence of unsafe factors.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, illustrates the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0022] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms used in this specification such as "upper," "lower," "left," "right," "middle," "front," "back," "inner," "outer," "first," and "second," etc., are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model. Specific structures can be described with reference to the accompanying drawings of this patent application.

[0023] Please refer to Figures 1-4 As shown, the tire-mounted container cranes 6 in container terminals are all equipped with inflatable bias tires. The tire-mounted container cranes 6 are supported by these inflatable bias tires, and the movement of the entire equipment is achieved by driving the tires. This utility model discloses a tire for tire-mounted container cranes. The tire 1 is filled with filler 2 to make it a solid tire. The filler 2 is formed by mixing and solidifying granules and polymer material AB glue 22. In this embodiment, the granules are waste tire particles 21 processed and cut from waste tires. The shape and size of the waste tire particles 21 are 2CM*2CM*2CM. The proportion of waste tire particles 21 used in the tire 1 is 35%-40% of the internal volume of the tire 1.

[0024] It should be noted that the AB adhesive 22 has good fluidity before bonding, making it easy to fill the pneumatic bias tire under pressure. Simultaneously, the AB adhesive 22 has strong adhesion, and the hardened colloid exhibits good toughness, small deformation, and strong load-bearing capacity. After mixing and hardening with waste tire particles 21, the AB adhesive 22 forms a highly elastic whole, improving the tire's impact resistance, crack resistance, and load-bearing capacity. Its compressive strength reaches 30 MPa without cracking. Due to this structure, the pneumatic bias tires originally equipped on the tire-mounted container crane 6 are replaced with solid tires, which have strong impact resistance, crack resistance, and load-bearing capacity. Furthermore, the waste tires are reused, avoiding resource waste, reducing equipment maintenance and production costs. At the same time, there is no need to check tire pressure, saving manpower and avoiding unsafe factors such as human-machine cross-operation.

[0025] Furthermore, a number of vent holes 4 are drilled in the circumferential direction of the tire 1, which are used to expel the gas in the tire 1 when the filler is filled into the tire 1. The vent holes 4 are drilled in the tread grooves 11 of the tire 1, and the distance between two adjacent vent holes 4 is 3 tread grooves.

[0026] Furthermore, after the air is expelled from the tire 1 through the vent hole 4, it is secured with stainless steel flat-head self-tapping screws 5. Since the vent hole 4 is drilled in the tread groove 11, the rolling movement of the tire is not affected after the stainless steel flat-head self-tapping screws 5 are secured.

[0027] In implementing this utility model, waste tires are processed and cut into waste tire pellets 21, with a shape and size of 2CM*2CM*2CM. The waste tire pellets 21 are pre-filled into the tire body 1 to be filled, with the optimal proportion being 35%-40% of the tire body 1's internal volume. The tire 1 pre-filled with waste tire pellets 21 is then installed on a wheel hub 3. The tire 1 is pre-inflated by injecting air through an air compressor connected to an inflation nozzle already mounted on the wheel hub 3. When the pressure inside the tire 1 reaches 0.4 MPa, the tire 1 is placed horizontally and rotated for 30 minutes. Under centrifugal force, the waste tire pellets 21 filled into the tire body are evenly distributed. Finally, a polymer AB glue 22 is filled into the tire 1, injected through a pneumatic pump via an inflation nozzle already mounted on the wheel hub 3. While observing the pressure inside tire 1, when the pressure inside tire 1 rises to 0.6Mpa-0.7Mpa, use a 5mm electric drill to drill holes in the tread grooves 11 of tire 1 to release air. The drilling interval is 3 tread grooves. Continue to fill tire 1 with polymer AB glue 22 to expel the air inside tire 1, so that no gaps are generated inside tire 1 and a solid effect is achieved. At the same time, observe whether there is any glue flowing out of the vent holes 4. When glue flows out of all vent holes 4, use 6mm*40mm 304 stainless steel flat head self-tapping screws 5 to lock the vent holes 4. Then continue to fill tire 1 with polymer AB glue 22. When the pressure inside tire 1 reaches 1.0Mpa, stop filling polymer AB glue 22.

[0028] After filling, place the tire horizontally and rotate it for 30 minutes, then let it stand still for 10 days to allow the filler to solidify and harden before use.

[0029] In summary, compared with the prior art, due to this structure, the pneumatic bias tire is filled with a filler made of a mixture of granules and AB polymer material, which is then solidified and hardened, thus making it a solid tire and achieving the performance of a solid tire. Therefore, the beneficial effects of this utility model are:

[0030] 1. There is no need to check tire pressure or regularly inflate tires, which saves manpower and avoids the unsafe factors of human-machine cross-operation.

[0031] 2. Replaced tires are cut into waste tire pellets and used as filler material for reuse, which avoids waste of resources and reduces equipment maintenance and production costs.

[0032] 3. When pneumatic bias tires are filled into solid tires, their wear resistance and service life are improved. At the same time, tire explosion will not occur, which improves the stability of the entire equipment and avoids the occurrence of unsafe factors.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
