Description

Technical Field

[0001] This utility model relates to the field of lifting technology, and in particular to a rolling mill transfer lifting device. Background Technology

[0002] In automobile production, height differences (e.g., ±300mm) often exist between different workstations, requiring specialized transfer equipment to move parts or car bodies between these locations. Hydraulic transmission lifting platforms, as a traditional transfer and conveying equipment solution, play a crucial role in automotive production lines.

[0003] However, the normal operation of a hydraulic transmission lifting platform depends heavily on the cleanliness of the hydraulic system's oil. Oil contamination can easily lead to malfunctions such as hydraulic valve sticking and hydraulic cylinder failure. At the same time, the viscosity of hydraulic oil changes significantly with temperature. At high temperatures, the viscosity decreases, which may lead to increased leakage and internal leakage. At low temperatures, the viscosity increases, which will cause difficulties in system startup and reduced efficiency, seriously affecting the stable operation of the system. In emergency situations that require rapid response, the hydraulic system's action speed is relatively slow. Utility Model Content

[0030] The roller bed transfer lifting device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] This application provides a roller bed transfer lifting device, such as... Figures 1 to 5 As shown, the system includes a support frame 100 and a lifting platform 200 horizontally disposed within the support frame 100. A transmission mechanism 400 is provided between the lifting platform 200 and the support frame 100. A drive motor 300 is fixedly mounted on the lifting platform 200. The drive motor 300 is connected to and drives the transmission mechanism via a universal coupling 310, causing the lifting platform 200 to move up and down relative to the support frame 100, thereby meeting the displacement requirements of objects placed on the lifting platform 200. The transmission mechanism 400 is a rack and pinion transmission, including meshing gears 410 and gear components 420. The gears 410 are fixed to the support frame 100, and the gear components 420 are connected to the lifting platform 200. The drive motor 300 drives the gear components 420 to rotate, causing linear displacement relative to the gears 410, thereby causing the lifting platform 200 to move up and down relative to the support frame 100, achieving stable and high-precision lifting motion of the lifting platform 200. To increase the service life of the transmission mechanism 400, the gear component 420 is covered with a protective cover 430 and an oiler 440. The protective cover 430 is used to isolate external contaminants and reduce the pollution and corrosion of the transmission mechanism 400 by the external environment. The oiler 440 is connected to the meshing part of the transmission mechanism 400 and increases the lubrication of the transmission mechanism 400 by injecting lubricant into the meshing part.

[0032] The support frame 100 is a rectangular frame structure composed of multiple vertically erected columns 120 and crossbars connecting two columns 120. The bottom ends of the columns 120 are fixed to the ground or other horizontal bearing surface platform via a fixed base plate 110. Preferably, to increase the stability of the frame structure, two crossbars are horizontally connected between two adjacent columns 120, namely an upper crossbar 130 near the upper end of the column 120 and a lower crossbar 140 near the lower end. A bearing bracket 150 is provided between the upper crossbar 130 and the lower crossbar 140. The bearing bracket 150 is located between two adjacent columns 120 and is arranged parallel to the columns 120. The gear condition 410 is axially fixed to the bearing bracket 150 to meet the vertical displacement requirements of the gear component 420 relative to the gear condition 410.

[0033] The lifting platform 200 includes two parallel, spaced-apart first connecting rods 210 and two second connecting rods 220 that connect and fix the two ends of the first connecting rods 210 respectively. The two first connecting rods 210 and the two second connecting rods 220 form a stable horizontal frame structure. The second connecting rods 220 are correspondingly arranged with the support bracket 150. A gear component 420 that meshes with the gear condition 410 is fixedly mounted on the second connecting rod 220. A drive bracket 260 for supporting the drive motor 300 is also provided between the two first connecting rods 210. The drive motor 300 is fixedly mounted on the drive bracket 260 and connected to the gear component 420 via a universal coupling 310 for power output, driving the gear component 420 to rotate. The gear component 420 meshes with the gear condition 410, causing the gear component 420 to move vertically along the gear condition 410, thereby realizing the lifting of the lifting platform 200. Preferably, to increase the practicality of the lifting platform 200, multiple support rods 230 are vertically provided on the first connecting rod 210. Support plates 240 are fixed to the ends of the support rods 230. The upper surfaces of the multiple support plates 240 are coplanar. Preferably, the upper surfaces of the multiple support plates 240 are located on the same horizontal plane to facilitate stable support and connection of objects placed on the lifting platform 200. In one example, to increase the service life of the lifting platform 200, a reinforcing member 250 is also provided between the support rods 230 and the first connecting rod 210 to increase the rigidity of the connection structure between the support rods 230 and the first connecting rod 210.

[0034] One embodiment relates to a rolling mill transfer lifting device, wherein a guide mechanism is provided between the lifting platform 200 and the support frame 100, including a guide rail 180 fixed to a column 120 and a slider 280 fixed to a second connecting rod 220, the slider 280 and the guide rail 180 slidingly engaging in the vertical direction. In one example, a guide seat 270 is fixedly provided on the second connecting rod 220 near the column 120, and the slider 280 is embedded in the guide seat 270 facing the column 120. The first column 120 is fixedly provided with a guide rail 180 that engages with the slider 280, the guide rail 180 and the slider 280 slidingly engaging in the vertical direction. When the lifting platform 200 moves up and down relative to the support frame 100, the slider 280 slides up and down along the guide rail 180 to ensure the smooth movement of the lifting platform 200.

[0035] In one embodiment, a roller bed transfer lifting device is provided. The column 120 is provided with at least two position sensors 160, located at the upper end and the lower end of the column 120 respectively. The lifting platform 200 is provided with a sensing element 290 that cooperates with the position sensors 160. When the lifting platform 200 moves up and down until the sensing element 290 corresponds to the position sensor 160, a stop mechanism is triggered, and the lifting platform 200 stops moving, thereby realizing the control of the lifting stroke of the lifting platform 200.

[0036] One embodiment relates to a roller bed transfer lifting device, wherein a drag chain 170 is provided between the column 120 and the lifting platform 200 to protect the pipeline connecting the support frame 100 and the lifting platform 200, thereby increasing the aesthetics of the lifting device, reducing the probability of pipeline interference and wear, and extending the service life of the lifting device.

[0037] The roller bed transfer lifting device provided by this utility model, through the cooperation of a drive motor and a gear and rack transmission mechanism, replaces the hydraulic transmission lifting in existing transfer equipment. It features a simple structure, fast response speed, and precise lifting control with an accurate transmission ratio, ensuring the lifting platform stops precisely at a predetermined position. This is crucial for the precise handling of parts or car bodies in automotive production lines, effectively improving production efficiency and quality. Compared to hydraulic systems, gear and rack transmission is unaffected by oil contamination and temperature changes, resulting in a lower failure rate and higher reliability. Gear and rack transmission better adapts to high-intensity production demands, bearing larger loads and achieving higher lifting speeds, significantly improving operating efficiency compared to traditional hydraulic lifting platforms. This is particularly advantageous for frequent material handling and transfer in automotive production lines. The gear and rack transmission structure is relatively simple, requiring less maintenance and incurring lower costs. Compared to hydraulic systems, it eliminates the need for regular hydraulic oil changes and filter cleaning, reducing maintenance time and costs. Gear and rack transmission lifting platforms can be customized to different working conditions and needs, suitable for various automotive production line scenarios. For example, the length of the rack and the size of the gears can be adjusted according to the height and load requirements of the production line. Gear and rack transmissions operate with low noise, providing a quieter working environment for operators.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
