Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller technology, and in particular to a high-torque roller for heavy lifting. Background Technology
[0002] Electric rollers are a new type of drive device that integrates a motor and a reducer inside the roller body. Heavy-duty high-torque rollers are key components in lifting equipment, responsible for bearing and transmitting enormous torque to drive the operation of the lifting system.
[0003] In the existing technology, lubricating oil is used inside the drum to lubricate and cool the gears. However, when the gears are working, they produce waste debris that gets mixed into the lubricating oil. During use, the debris in the lubricating oil moves upward with the rotation of the drum. When it reaches the top, it falls down under its own gravity. The debris falls downward between the transmission gears, causing more severe wear on the gears and affecting the working life of the drum. Summary of the Invention
[0004] The purpose of this invention is to solve the problem in the prior art where lubricating oil contains debris that falls onto the transmission gears, accelerating gear wear and affecting the service life of the drum. Therefore, this invention proposes a high-torque drum for heavy lifting.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heavy-duty lifting high-torque roller, comprising an outer cylinder, with a first sealing plate installed at both ends of the outer cylinder, an oil scraper frame fixedly connected inside the outer cylinder, an inclined filter plate fixedly connected inside the oil scraper frame, a feed inlet on one side of the oil scraper frame, a collection frame fixedly connected to one side of the feed inlet, a baffle fixedly connected to the side of the oil scraper frame, and an oil leakage outlet on one side of the oil scraper frame.
[0006] Preferably, a transmission assembly is installed inside the outer cylinder, with both ends of the transmission assembly passing through two first sealing plates, and both ends of the transmission assembly being rotatably connected to a fixed seat.
[0007] Preferably, a second sealing plate is fixedly connected to one side of the first sealing plate, and the second sealing plate is sleeved on the end of the transmission assembly.
[0008] Preferably, a fixing collar is fixedly connected to one side of the second sealing plate, and an annular groove is formed on the outer surface of the fixing collar.
[0009] Preferably, a sliding push block is slidably connected inside the annular groove, and a threaded sleeve is fixedly connected to one end of the sliding push block.
[0010] Preferably, the threaded sleeve has an internal threaded connection to a threaded rod, one end of which passes through one end of the threaded sleeve.
[0011] Preferably, one end of the threaded rod is rotatably connected to a fixing block, and one end of the fixing block is fixedly connected to the outer surface of the fixing seat.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, multiple oil scraping frames are distributed in a ring inside the outer cylinder. When the oil scraping frame at the bottom gradually moves upward, it scrapes up the lubricating oil deposited at the bottom of the outer cylinder. The inclined filter plate filters out the waste debris inside the lubricating oil. The waste debris enters the inside of the collection frame from the feed port and is collected in the collection frame. This prevents the waste debris from falling into the transmission gears along with the rotation of the outer cylinder and causing wear, thereby improving the overall service life of the roller.
[0014] 2. In this utility model, the distance between the fixed block and the sliding push block is adjusted by rotating the threaded rod, which can push the fixed collar and the second sealing plate to move, so that the second sealing plate is always in close contact with one side of the first sealing plate, preventing the second sealing plate and the first sealing plate from loosening during the operation of the roller, and improving the sealing effect inside the outer cylinder.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figures 1-4 As shown, this utility model provides a heavy-duty lifting high-torque roller, including an outer cylinder 1, with first sealing plates 2 installed at both ends of the outer cylinder 1, an oil scraper 6 fixedly connected inside the outer cylinder 1, an inclined filter plate 7 fixedly connected inside the oil scraper 6, a feed inlet 10 opened on one side of the oil scraper 6, a collection frame 8 fixedly connected to one side of the feed inlet 10, a baffle 9 fixedly connected to the side of the oil scraper 6, and an oil leakage outlet 11 opened on one side of the oil scraper 6; a transmission assembly 4 is installed inside the outer cylinder 1, with both ends of the transmission assembly 4 passing through the two first sealing plates 2 respectively, and both ends of the transmission assembly 4 are rotatably connected to a fixed seat 3.
[0024] Two fixed seats 3 are used to support and position the two ends of the transmission assembly 4. The transmission assembly 4 consists of a connecting shaft, a motor assembly, a gearbox assembly, and a gear ring, which drives the outer cylinder 1 to rotate. Multiple oil scraper frames 6 are arranged in a ring inside the outer cylinder 1. As the outer cylinder 1 rotates, the oil scraper frames 6 rotate accordingly. When the bottom oil scraper frame 6 gradually moves upward, the opening on one side of the oil scraper frame 6 scrapes the lubricating oil deposited at the bottom of the outer cylinder 1 upward. The lubricating oil enters the interior of the oil scraper frame 6. The oil scraper frame 6 is equipped with... There is an inclined filter plate 7, which is inclined towards the feed inlet 10 to filter out the waste debris inside the lubricating oil. The waste debris moves on the inclined filter plate 7 and enters the inside of the collection frame 8 from the feed inlet 10. When the oil scraper 6 rotates to the top, the filtered lubricating oil flows out from the oil drain 11 and falls to lubricate the transmission component 4. The waste debris is collected in the inside of the collection frame 8 to prevent it from falling between the transmission gears along with the rotation of the outer cylinder 1 and causing wear, thus improving the overall service life of the drum.
[0025] Example 2: Figure 1 and Figure 5As shown, a second sealing plate 5 is fixedly connected to one side of the first sealing plate 2, and the second sealing plate 5 is sleeved on the end of the transmission assembly 4; a fixing collar 13 is fixedly connected to one side of the second sealing plate 5, and an annular groove 12 is formed on the outer surface of the fixing collar 13; a sliding push block 17 is slidably connected inside the annular groove 12, and a threaded sleeve 16 is fixedly connected to one end of the sliding push block 17; a threaded rod 15 is threadedly connected inside the threaded sleeve 16, and one end of the threaded rod 15 passes through one end of the threaded sleeve 16; a fixing block 14 is rotatably connected to one end of the threaded rod 15, and one end of the fixing block 14 is fixedly connected to the outer surface of the fixing seat 3.
[0026] The overall effect of this embodiment is that, through the threaded connection between the threaded rod 15 and the threaded sleeve 16, the length of the threaded rod 15 entering the threaded sleeve 16 can be adjusted during the rotation of the threaded rod 15, thereby adjusting the distance between the fixed block 14 and the sliding push block 17. This allows the fixed collar 13 and the second sealing plate 5 to move, ensuring that the second sealing plate 5 is always tightly attached to one side of the first sealing plate 2. This prevents the second sealing plate 5 and the first sealing plate 2 from loosening during the operation of the roller, improving the sealing effect inside the outer cylinder 1. At the same time, through the sliding push block 17 slidingly connected to the annular groove 12, when the first sealing plate 2 and the second sealing plate 5 rotate with the outer cylinder 1, the sliding push block 17 slides within the annular groove 12, preventing motion interference.
[0027] The operating method and working principle of this device are as follows: The outer cylinder 1 is driven to rotate by the transmission component 4. Multiple oil scraping frames 6 are distributed in a ring inside the outer cylinder 1. As the outer cylinder 1 rotates, the oil scraping frames 6 at the bottom gradually move upward, scraping up the lubricating oil deposited at the bottom of the outer cylinder 1. The lubricating oil enters the interior of the oil scraping frames 6. The inclined filter plate 7 filters out the waste debris inside the lubricating oil. The waste debris enters the interior of the collection frame 8 from the feed port 10. When the oil scraping frame 6 rotates to the top, the filtered lubricating oil flows out from the oil drain port 11 and falls to lubricate the transmission component 4. By rotating the threaded rod 15, the distance between the fixed block 14 and the sliding push block 17 can be adjusted, which can push the fixed collar 13 and the second sealing plate 5 to move, so that the second sealing plate 5 is always in close contact with one side of the first sealing plate 2, preventing the second sealing plate 5 and the first sealing plate 2 from loosening during the operation of the drum.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
