Description

A split nylon wheel Technical Field

[0001] This utility model relates to the technical field of walking nylon wheel equipment for pre-sedimentation tanks, specifically a split nylon wheel. Background Technology

[0002] Nylon wheels in pre-sedimentation tanks are mainly used in the drive or transmission parts of equipment. In some pre-sedimentation tank scraper equipment, nylon wheels can serve as walking wheels. Their wear-resistant and corrosion-resistant properties allow them to adapt to the complex environment of the pre-sedimentation tank, which is often damp and muddy. This effectively reduces friction during equipment operation, ensuring the scraper moves stably on the tank side track, scraping the sediment and other materials settled at the bottom of the tank into the sludge hopper, thereby improving the sedimentation efficiency of the pre-sedimentation tank.

[0003] Pre-sedimentation tanks are crucial wastewater treatment equipment, and nylon wheels are a key component of this facility. The sludge scraper in the pre-sedimentation tank is driven by a motor and reducer located above the tank, propelling the nylon wheel along a predetermined track to scrape the sludge from the bottom of the tank. However, because the nylon wheel is an assembly of a cast steel wheel body and a nylon outer hub, a common problem during use is the separation of the outer hub from the inner cast steel wheel body. This defect severely impacts the normal operation of the pre-sedimentation tank, while also wasting spare parts and incurring high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a split nylon wheel to solve the problem in the background art where the nylon outer hub and the inner cast steel wheel body often separate during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split-type nylon wheel, comprising an outer hub and a metal wheel body. The outer hub is fixedly sleeved on the outer wheel surface of the metal wheel body. The metal wheel body has a through hole inside, in which a coaxially arranged axle is embedded. The split-type nylon wheel also includes a pressure plate and fastening screws. The pressure plate is evenly attached to the two side walls of the outer hub and the metal wheel body. The first end of the pressure plate is lower than the outer wheel surface of the outer hub and higher than the inner wheel surface of the outer hub. The second end of the pressure plate is lower than the outer wheel surface of the metal wheel body and higher than the inner wheel surface of the metal wheel body. The wheel wall of the metal wheel body has screw holes. The fastening screws pass through the pressure plate and are detachably fixed in the screw holes of the metal wheel body, with the screw heads of the fastening screws pressing against the pressure plate.

[0006] Based on the above technical features, the split-type nylon wheel of this invention includes an outer hub and a metal wheel body, which are separate components. The internal metal wheel body is reusable. When the outer hub is damaged and can no longer be used, the outer hub on the metal wheel body can be replaced, improving the utilization rate of the device. At the same time, the split structure can also ensure that the nylon wheel has a certain rigidity and elasticity, improving the impact resistance and cushioning performance of the nylon wheel. In addition, this invention adds pressure plates to both sides of the nylon wheel and fastens the pressure plates with fastening screws to prevent the outer hub from detaching from the metal wheel body and from running off-center during operation, thus improving the service life of the nylon wheel.

[0007] Preferably, in this technical solution, the pressure plate is ring-shaped and there are two of them. The two ring-shaped pressure plates are respectively attached to the two side walls of the outer hub and the metal wheel body. The outer ring surface of the pressure plate is lower than the outer wheel surface of the outer hub and higher than the inner wheel surface of the outer hub. The inner ring surface of the pressure plate is lower than the outer wheel surface of the metal wheel body and higher than the inner wheel surface of the metal wheel body. More preferably, the screw holes opened on the wheel wall of the metal wheel body are arranged in a ring.

[0008] Based on the above technical features, the ring-shaped pressure plate can provide more stable support and fixation, ensuring that the outer hub and metal wheel body of the nylon wheel remain stable during operation, and preventing detachment and deviation.

[0009] In this technical solution, preferably, there is an interference fit between the outer hub and the metal wheel body.

[0010] Preferably, in this technical solution, the split nylon wheel further includes a fixing pin, which is disposed between the outer hub and the metal wheel body, and the outer hub and the metal wheel body are reinforced and secured by the fixing pin. More preferably, the fixing pin has a wedge-shaped structure.

[0011] Based on the above technical features, a fixing pin is added between the outer hub and the metal wheel body to effectively prevent relative rotation between the two during operation.

[0012] Preferably, in this technical solution, a keyway that mates with the axle is provided in the through hole of the metal wheel body.

[0013] In this technical solution, the outer hub is preferably made of nylon, and the metal wheel body is made of cast steel.

[0014] Based on the above technical features, the outer hub is made of nylon material, which improves the high strength and wear resistance of the nylon wheel, effectively resisting accidental impacts and wear during long-term use. At the same time, nylon material also has excellent impact resistance. Attached Figure Description

The second end of the pressure plate 2 is lower than the outer wheel surface of the metal wheel body 3 and higher than the inner wheel surface of the metal wheel body 3. The metal wheel body 3 has screw holes on its side walls. The fastening screws 6 pass through the pressure plate 2 and are detachably fixed into the screw holes of the metal wheel body 3, with the screw heads of the fastening screws 6 pressing firmly against the pressure plate 2. By adding pressure plates 2 to the two side walls of the nylon wheel and fastening them with fastening screws 6, the nylon wheel is prevented from detaching from the outer hub 1 and the metal wheel body 3 during operation, thus improving the service life of the nylon wheel.

[0027] Specifically, as shown in Figures 1 and 2, the pressure plate 2 is ring-shaped and there are two of them. The two ring-shaped pressure plates 2 are respectively attached to the two side walls of the outer hub 1 and the metal wheel body 3. The outer ring surface of the pressure plate 2 is lower than the outer wheel surface of the outer hub 1 and higher than the inner wheel surface of the outer hub 1.
