[0015] (1) The servo motor drives the rotating shaft to rotate clockwise. The rotating shaft drives two sets of first sprockets to rotate. With the cooperation of the counterweight body, two sets of first chain bodies, second chain bodies, and multiple sets of movable blocks, the first sprocket drives the first chain body to rotate.

[0016] (2) A set of movable blocks drives a set of telescopic columns and support blocks to move upward. At this time, the support blocks drive the spring to compress. Since the hollow box supports the spring, the hollow box will only start to move upward when the spring compression is at its maximum. The spring plays the role of elastic buffer. The hollow box drives the support plate, support arm, conveyor, roller and material to move upward. The spring reduces the instantaneous tension during lifting, realizes the convenient buffering and lifting of materials by the single column lift, reduces the instantaneous tension during lifting, and extends the service life of the single column lift.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figure 1-10This utility model provides an embodiment of a single-column lifting platform for material transportation, comprising a column body 1 and a base plate 2. The base plate 2 is installed at the bottom end of the column body 1, and a top plate 3 is installed at the top end of the column body 1. A protective cover 4 is installed at the top end of the top plate 3. A support plate 10 is provided on the outside of the column body 1. U-shaped frames 11 are installed on both sides of the support plate 10. Support arms 5 are symmetrically installed on the side walls of the support plate 10. A conveyor 6 is installed at the top end of the support arms 5. Multiple sets of rollers 7 with equal spacing are movably installed on both sides of the conveyor 6. Four sets of buffers 8 with equal spacing are installed at the top end of the base plate 2. A servo motor 13 is installed on the side of the top end of the base plate 2 away from the buffers 8. A rotating shaft 14 is installed at the output end of the servo motor 13. The rotating shaft 14 extends through the column body 1 to its exterior and is movably connected to it. Two sets of first sprockets 15 are fitted on the surface of the rotating shaft 14. The surface of each first sprocket 15 is fitted with a first chain body 16. Two sets of movable blocks 21 are symmetrically arranged on the exterior of the support plate 10. One end of each first chain body 16 is connected to a set of movable blocks 21. The top of the top plate 3 inside the protective cover 4 is symmetrically equipped with I-beams 28. A second shaft 29 is movably installed between the two sets of I-beams 28. Two sets of second sprockets 30 are fitted on the surface of the second shaft 29. The surface of each second sprocket 30 is fitted with a second chain body 22. One end of each second chain body 22 is connected to another set of movable blocks 21. A counterweight body 31 is arranged inside the column body 1.

[0031] When using a single-column lifting platform for material transport, the conveyor 6 is turned on. Supported by the support arm 5 and limited by multiple sets of rollers 7, the material is conveyed to the surface of the conveyor 6. The conveyor 6 is then turned off, and the servo motor 13 is turned on. Supported by the base plate 2, the servo motor 13 drives the rotating shaft 14 to rotate clockwise. The rotating shaft 14 drives two sets of first sprockets 15 to rotate. With the cooperation of the counterweight body 31, two sets of first chain bodies 16, second chain bodies 22, and multiple sets of movable blocks 21, the first sprockets 15 drive the first chain bodies 16 to rotate. The chain body 16 drives the counterweight body 31 to move downward, and the counterweight body 31 drives the second chain body 22 to descend. With the support of the second shaft 29 and the second sprocket 30, the second chain body 22 drives the support plate 10 to move upward. The first chain body 16 limits the support plate 10, so that the support plate 10 drives the support arm 5, the conveyor 6, the roller 7, and the material to be lifted upward. This realizes the convenient lifting of materials by the single column lift, facilitates the reliable support transmission of multiple structures, and improves the stability of material operation during lifting.

[0032] Two sets of hollow boxes 17 are symmetrically installed on the side wall of the support plate 10, and telescopic columns 23 are movably installed inside the hollow boxes 17.

[0033] All telescopic columns 23 extend through the hollow box 17 to its outside. One end of each telescopic column 23 is equipped with a support block 19, and the surface of each support block 19 is equipped with a spring 18.

[0034] All springs 18 extend into the interior of the hollow box 17, and the other end of each telescopic column 23 is movably mounted with a support shaft 20. Each telescopic column 23 is movably connected to the movable block 21 through the support shaft 20.

[0035] During lifting, the first chain body 16 drives the counterweight body 31 to move downwards, and the counterweight body 31 drives the second chain body 22 to descend. Supported by the second shaft 29 and the second sprocket 30, the second chain body 22 drives a set of movable blocks 21 to move upwards. With the movable support of the support shaft 20, the set of movable blocks 21 drives a set of telescopic columns 23 and support blocks 19 to move upwards. At this time, the support blocks 19 drive the spring 18 to compress. Since the hollow box 17 supports the spring 18, the hollow box 17 only starts to move upwards when the spring 18 is compressed to its maximum. The spring 18 plays the role of elastic buffer. The hollow box 17 drives the support plate 10, support arm 5, conveyor 6, roller 7, and material to move upwards. The spring 18 reduces the instantaneous tension during lifting, reduces the mechanical strength of instantaneous lifting, reduces the fatigue of the mechanical structure, and extends the service life of the single column lift. It realizes the convenient buffering and lifting of materials by the single column lift, reduces the instantaneous tension during lifting, and extends the service life of the single column lift.

[0036] Slide rails 9 are symmetrically installed on the side wall of the column body 1. Limit blocks 12 are installed at both ends of the slide rails 9. Rotating shafts 24 are symmetrically and movably installed on the side wall of the U-shaped frame 11. First rollers 25 are fitted on the surface of the rotating shafts 24. The first rollers 25 slide through the U-shaped frame 11 and are slidably connected to the slide rails 9.

[0037] Two sets of first shafts 26 are symmetrically and movably installed on the surface of the U-shaped frame 11. The first shafts 26 extend through the U-shaped frame 11 to its outside. The surface of the first shafts 26 is fitted with second rollers 27.

[0038] The second rollers 27 are all slidably connected to the slide rail 9, the bottom of the counterweight body 31 is connected to the first chain body 16, and the top of the counterweight body 31 is connected to the second chain body 22.

[0039] A third shaft 32 is symmetrically and movably installed on the top side wall of the counterweight body 31. A third roller 33 is fitted on the surface of the third shaft 32, and the third roller 33 is slidably connected to the column body 1.

[0040] During the ascent, under the limit of the slide rail 9, the first roller 25 and the second roller 27 on the surface of the two sets of U-shaped frames 11 slide on the surface of the slide rail 9. The upper and lower limit blocks 12 limit the U-shaped frames 11 to prevent the U-shaped frames 11 from having too large a stroke when moving up and down, which could cause the safety hazard of hitting the top or falling. This ensures the stability during lifting and avoids derailment during lifting. The counterweight block body 31 slides inside the column body 1, ensuring the tension of the first chain and the second chain during operation. This enables the single column lift to lift quickly and stably, facilitates reliable sliding support for multiple structures, and improves the stability of the single column lift during lifting.

[0041] Working principle: Servo motor 13 drives rotating shaft 14 to rotate clockwise. Rotating shaft 14 drives two sets of first sprockets 15 to rotate. With the cooperation of counterweight body 31, two sets of first chain bodies 16, second chain bodies 22, and multiple sets of movable blocks 21, the first sprockets 15 drive the first chain bodies 16 to rotate. The first chain bodies 16 drive the counterweight body 31 to move downward. The counterweight body 31 drives the second chain bodies 22 to descend. The second chain bodies 22 drive the support plate 10 to move upward. The first chain bodies 16 limit the support plate 10, thereby causing the support plate 10 to lift the support arm 5, conveyor 6, roller 7, and material upward. At this time, the support block 1... The drive spring 18 is compressed. Since the hollow box 17 supports the spring 18, the hollow box 17 only starts to move upward when the spring 18 is compressed to its maximum. The spring 18 acts as an elastic buffer. The hollow box 17 drives the support plate 10, support arm 5, conveyor 6, roller 7, and material to move upward. The spring 18 reduces the instantaneous tension during lifting. During the upward process, under the limit of the slide rail 9, the first roller 25 and the second roller 27 on the surface of the two sets of U-shaped frames 11 slide on the surface of the slide rail 9. The upper and lower limit blocks 12 limit the U-shaped frames 11 to prevent the U-shaped frames 11 from having too large a stroke when moving up and down, which could cause the safety hazard of hitting the top or falling, and ensure the stability during lifting.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
