Description

Technical Field

[0001] The utility model relates to a steel core rubber coated wheel, in particular to a steel core rubber coated wheel for a conveyor of heavy carton equipment. Background Art

[0002] Conveyors are used for transporting materials, generally divided into roller type or belt type. In the roller type, the rollers are relatively important components, playing a role in supporting and forward conveying.

[0003] For example, the patent with application number CN201711038484.9 discloses a roller conveyor, including: a base, a conveying device, a blocking device, and a driving device for providing driving force for the conveying device. Support feet are provided at the four corners of the base, and pulleys for pushing the base to move are installed on the support feet. The conveying device and the driving device are both installed on the base, and the blocking device is installed at the output end of the base; the conveying device includes a plurality of rollers, rotating gears corresponding to the rollers one by one, and a conveyor belt. The rotating gears are installed on the base, one end of the roller is rotatably installed on the base, the other end is rotatably installed on the rotating gear, and a plurality of rotating gears are in transmission connection with the conveyor belt, and the conveyor belt is in driving connection with the driving device.

[0004] As described in the above patent, the rollers are installed on the base. However, the existing rollers are generally ordinary steel wheels, which are mainly made of steel, having good strength and wear resistance, but a relatively large friction coefficient, which easily leads to increased wear on the track surface. Therefore, generally, a rubber coated wheel formed by wrapping a steel core with rubber is used to provide sufficient load bearing and reduce friction. However, when transporting large objects, such as heavy cartons, the length of the rollers increases significantly. Therefore, it is somewhat difficult to press the internal steel core into the outer wheel body for interference fit during installation. Summary of the Utility Model

[0005] Based on the deficiency in the prior art that it is not easy to press the steel core of the long rubber coated wheel into the outer wheel body, the utility model provides a steel core rubber coated wheel for a conveyor of heavy carton equipment.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0007] A steel core rubber coated wheel for a conveyor of heavy carton equipment, including an internal steel core and a rubber coated outer wheel body sleeved on the steel core. The steel core includes a first steel core, a second steel core, and a third steel core that are cylindrical and have a shaft hole in the middle. The first steel core, the second steel core, and the third steel core are coaxially arranged and abut against each other in sequence, and the rubber coated outer wheel body covers the side walls of the three and is in close fit with the side walls of the three.

[0008] Preferably, the outer diameters of the first steel core and the third steel core are equal and larger than the outer diameter of the second steel core.

[0009] Preferably, the inner ends of the first steel core and the third steel core are both provided with abutting sections whose outer diameters gradually decrease from outside to inside, and the rubber-coated outer wheel body has a frustum-shaped hole that fits the shape of the abutting sections.

[0010] Preferably, a limiting structure for restricting relative rotation is provided between the first steel core and the second steel core, and between the second steel core and the third steel core.

[0011] Preferably, the limiting structure includes a limiting boss and a limiting groove, the shapes of the limiting boss and the limiting groove match, and the limiting boss can extend into the limiting groove.

[0012] Preferably, the outer ends of the first steel core and the third steel core extend outward to form limiting rings, and the limiting rings abut against the end faces of the rubber-coated outer wheel body.

[0013] Preferably, the rubber-coated outer wheel body is closely attached to the first steel core, the second steel core, and the third steel core by providing an adhesive layer or interference fit.

[0014] Preferably, a shaft rod is inserted into the shaft holes in the middle of the first steel core, the second steel core, and the third steel core.

[0015] Preferably, bearings are provided in the shaft holes of the first steel core, the second steel core, and the third steel core, and the shaft rod is in interference fit with the bearings; or the shaft holes are non-circular holes, and the shaft rod is arranged in the shaft holes.

[0016] Preferably, the rubber-coated outer wheel body is a polyurethane wheel body.

[0017] Compared with the prior art, the advantages of the present utility model are as follows: In this application, the steel core is segmented and the inner holes of the outer wheel body are also segmented.

[0026] Embodiment

[0027] This embodiment mainly elaborates on the title of the portable UAV landing platform, as follows:

[0028] Referring to Figures 1 - 4 , a steel core rubber-coated wheel for a heavy cardboard box equipment conveyor includes a steel core 10 inside and a rubber-coated outer wheel body 20 sleeved on the steel core 10. The steel core 10 includes a first steel core 101, a second steel core 102, and a third steel core 103 that are cylindrical and have a shaft hole in the middle. The first steel core 101, the second steel core 102, and the third steel core 103 are coaxially arranged and abut against each other in sequence, and the rubber-coated outer wheel body 20 covers the side walls of the three and is in close fit with the side walls of the three. In this solution, the steel core 10 is segmented and the inner hole of the outer wheel body 20 is also segmented. During installation, the steel core 10 can be segmented and pressed into the inside of the outer wheel body 20, and then the shaft rod 30 is inserted into the shaft hole provided in the middle of the steel core 10 to complete the installation. While the installation difficulty is greatly reduced, its load-bearing capacity is improved, and the friction coefficient on the surface of the finished product is reduced, which is beneficial to the transportation of cardboard boxes. In addition, the outer wheel body 20 can be replaced after wear.

[0029] Preferably, the outer diameters of the first steel core 101 and the third steel core 103 are equal and larger than the outer diameter of the second steel core 102. The different diameter settings are beneficial for pressing in.

[0030] Such as Figure 3 and 4As shown, abutting sections 105 with gradually decreasing outer diameters from outside to inside are provided at the inner ends of the first steel core 101 and the third steel core 103. The rubber-coated outer wheel body 20 has a frustum-shaped hole that fits the shape of the abutting section 105. This structure can guide and limit the position during pressing, preventing excessive pressing.

[0031] As Figure 3 shown, a limiting structure for restricting relative rotation is provided between the first steel core 101 and the second steel core 102, and between the second steel core 102 and the third steel core 103; the limiting structure includes a limiting boss 401 and a limiting groove 402, the limiting boss 401 and the limiting groove 402 have matching shapes and the limiting boss 401 can extend into the limiting groove 402. This limiting structure can prevent the adjacent steel cores 10 from having relative circumferential rotation.

[0032] As Figure 3 shown, the outer edge of the outer ends of the first steel core 101 and the third steel core 103 extends outward to form a limiting ring 104, and the limiting ring 104 abuts against the end face of the rubber-coated outer wheel body 20. The limiting ring 104 axially limits the rubber-coated outer wheel body 20, increasing the stability.

[0033] Preferably, the rubber-coated outer wheel body 20 is closely attached to the first steel core 101, the second steel core 102, and the third steel core 103 by setting an adhesive layer or interference fit. In the actual production process, since setting the adhesive will result in relatively low connection stability, generally, an interference fit structure is adopted and press-fitting is required during installation.

[0034] Preferably, a shaft rod 30 is inserted through the shaft holes in the middle of the first steel core 101, the second steel core 102, and the third steel core 103.

[0035] Preferably, bearings are provided in the shaft holes of the first steel core 101, the second steel core 102, and the third steel core 103, and the shaft rod 30 is in interference fit with the bearings. This structure does not provide traction; or the shaft holes are non-circular holes, and the shaft rod 30 is arranged in the shaft holes. This structure can provide traction.

[0036] Preferably, the rubber-coated outer wheel body 20 is a polyurethane wheel body. The polyurethane material has low cost and a small friction coefficient, and it has certain advantages as the surface material of the wheel body.

[0037] The above has introduced in detail the title of a steel core rubber-coated wheel for a heavy cardboard box equipment conveyor provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
