Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, specifically an adjustable roller lift. Background Technology

[0002] A lifting platform is a type of lifting machinery that transports people or goods vertically. In furniture production lines, roller lifts are commonly used to transport boards, bringing great convenience to production operations. Most common roller lifts have a fixed structure, lacking mobility or having inflexible movement capabilities. Their support structures are mostly fixed, preventing flexible adjustment of the platform height according to actual needs, making them difficult to adapt to the logistics requirements of complex environments. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides an adjustable roller lift, including a base with a slide rail on it, a scissor lift assembly on the base, and a roller lift assembly on the scissor lift assembly. The scissor lift assembly includes a first scissor arm, a second scissor arm, a crossbeam, a support frame, and a lifting hydraulic cylinder. The first and second scissor arms are hinged together at their middle portions via the crossbeam. The lower ends of the first and second scissor arms are connected to the support frame, which houses the lifting hydraulic cylinder. The output end of the lifting hydraulic cylinder is connected to one side of the crossbeam. One lower end of the first and second scissor arms is hinged to the base, and the other lower end of each of the first and second scissor arms is provided with a pulley, which slides along the slide rail. The roller assembly comprises an outer frame and an inner frame. Scissor arms one and two are hinged to the inner frame. The inner frame is located inside the outer frame. Several rollers are rotatably connected within the outer frame, with equal distances between adjacent rollers. Several fixing strips are welded within the inner frame, with equal distances between adjacent fixing strips, and the rollers are spaced apart from the fixing strips. One side of the roller assembly is hinged to the adjusting platform. Several thin rollers are provided within the adjusting platform, with equal distances between adjacent thin rollers. Several connecting grooves are spaced apart at the lower end of the adjusting platform, and the connecting grooves have threaded holes. Fasteners fix the adjusting platform and the transmission component through the threaded holes. The transmission component is connected to the output end of the telescopic motor, which is located on the crossbeam of the scissor assembly.

[0004] The base has several rollers on its left and right sides, and each roller is equipped with a locking device.

[0005] The base has several limiting posts welded on its left and right sides.

[0006] The lower ends of the scissor arms one and two are connected by a connecting rod, with the pulleys located at both ends of the connecting rod.

[0007] The height of the upper surface of the fixing bar is lower than the height of the upper generatrix of the roller.

[0008] The transmission component includes a lead screw, a bracket, and a hollow crossbar. The lead screw passes through the output end of the telescopic motor, and brackets are provided at both ends of the lead screw. The upper end of the bracket is connected to the hollow crossbar. The hollow crossbar has mounting holes that are opposite to the threaded holes of the connecting groove. Fasteners fix the adjustment platform and the transmission component together through the threaded holes of the connecting groove and the mounting holes of the hollow crossbar.

[0009] Compared with the prior art, this utility model adds a mobility function and height adjustment, which improves the flexibility of the equipment, ensures the stability and load-bearing capacity of the equipment, and enhances the conveying efficiency and applicability.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figures 1 to 5An adjustable roller lift includes a base 1, a slide rail 2 on the base 1, a scissor lift assembly on the base 1, and a roller lift assembly 9 on the scissor lift assembly. The scissor lift assembly includes a first scissor arm 3, a second scissor arm 4, a crossbeam 5, a support frame 6, and a lifting hydraulic cylinder 7. The first scissor arm 3 and the second scissor arm 4 are hinged at the middle by the crossbeam 5. The lower ends of the first scissor arm 3 and the second scissor arm 4 are connected to the support frame 6. The support frame 6 is equipped with the lifting hydraulic cylinder 7. The output end of the lifting hydraulic cylinder 7 is connected to one side of the crossbeam 5. One side of the lower end of the first scissor arm 3 and the second scissor arm 4 is hinged to the base 1. The other side of the lower end of the first scissor arm 3 and the second scissor arm 4 are each equipped with a pulley 8, which is slidably connected to the slide rail 2 to ensure smooth sliding of the scissor lift assembly. The roller assembly includes an outer frame 10 and an inner frame 11. Scissor arms 1-3 and 2-4 are hinged to the inner frame 11. The inner frame 11 is located inside the outer frame 10. Several rollers 12 are rotatably connected inside the outer frame 10, with equal distances between adjacent rollers 12. Several fixing bars 13 are welded inside the inner frame 11, with equal distances between adjacent fixing bars 13. The rollers 12 and fixing bars 13 are spaced apart. One side of the roller assembly 9 is hinged to the adjustment platform 14. Several thin rollers 15 are provided inside the adjustment platform 14, with equal distances between adjacent thin rollers 15. Several connecting grooves 16 are spaced apart at the lower end of the adjustment platform 14. The connecting grooves 16 have threaded holes. Fasteners fix the adjustment platform 14 and the transmission component 17 through the threaded holes. The transmission component 17 is connected to the output end of the telescopic motor 18. The telescopic motor 18 is located on the crossbeam 5 of the scissor assembly.

[0013] The base 1 has several rollers 19 on its left and right sides, and each roller 19 is equipped with a locking device to facilitate the movement and fixation of the equipment.

[0014] Several limiting posts 24 are welded on the left and right sides of the base 1 to limit the outer frame 10.

[0015] The lower ends of scissor arms 3 and 4 are connected by a connecting rod 20, with pulleys 8 located at both ends of the connecting rod 20.

[0016] The upper surface of the fixing bar 13 is lower than the height of the upper generatrix of the roller 12, ensuring that the goods are transported smoothly on the roller.

[0017] The transmission component 17 includes a lead screw 21, a bracket 22, and a hollow crossbar 23. The lead screw 21 passes through the output end of the telescopic motor 18. Brackets 22 are located at both ends of the lead screw 21, and the upper end of each bracket 22 is connected to the hollow crossbar 23. The hollow crossbar 23 has mounting holes corresponding to the threaded holes in the connecting groove 16. Fasteners securely connect the adjusting platform 14 and the transmission component 17 through the threaded holes in the connecting groove 16 and the mounting holes in the hollow crossbar 23. The connection position between the transmission component 17 and the connecting groove 16 can be adjusted according to actual needs to adjust the tilt angle of the adjusting platform 14.

[0018] In operation, the lifting hydraulic cylinder 7 is activated to lower the inner frame 11, and the outer frame 10 follows. When the outer frame 10 stops against the limit post 24, the inner frame 11 descends, and the fixing bar 13 is lower in the vertical direction than the roller 12. The telescopic motor 18 adjusts the adjusting platform 14 downwards, making it easier for workers to push goods onto the roller 12. Then, the lifting hydraulic cylinder 7 is activated to raise the inner frame 11, and the outer frame 10 rises with it, with the fixing bar 13 higher in the vertical direction than the roller 12. Depending on actual needs, the telescopic motor 18 adjusts the position of the adjusting platform 14 to be level with or tilted upwards towards the roller assembly 9, utilizing the rotation of the roller 12 and the thin roller 15 for transport, ensuring smooth transport of goods.
