[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This type of double-column lifting platform, during daily use, involves the operator starting the lifting motor. The motor's operation causes the lead screw to rotate, which in turn drives the lead sleeve to slide inside the main column. Subsequently, the lead sleeve drives the slider to slide inside the slide groove. At this point, the lead sleeve drives the connecting rod to slide, which in turn drives the moving block to slide inside the auxiliary column and on the surface of the round rod. Simultaneously, the connecting rod drives the lifting platform to slide, thus enabling lifting operations. The double-column design, with its main and auxiliary columns, provides balanced support for the lifting platform, ensuring good stability during lifting and effectively reducing swaying and tilting.

[0013] In daily use, the operator starts the rotary motor, which causes the threaded rod to rotate. The threaded rod then drives the sliding sleeve to slide inside the slot. At this time, the sliding sleeve drives the moving plate to slide until the moving plate extends to both sides of the base plate. Then, the throttle is turned, which drives the rotating rod to rotate inside the moving plate and slide downward. Subsequently, the rotating rod drives the outriggers to slide until the outriggers are on the working ground, thus providing auxiliary support for the lift and making it more stable.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a double-column lifting platform, including a base plate 1, of which there are two base plates 1, and the two base plates 1 are of the same size. A main column 2 is fixedly installed on the top of the base plate 1. A lead screw 3 is rotatably installed inside the main column 2. A threaded sleeve 4 is threaded onto the surface of the lead screw 3. When the lead screw 3 rotates, it will cause the threaded sleeve 4 to slide inside the main column 2, thereby adjusting the position of the threaded sleeve 4. A lifting motor 5 is fixedly installed on the top of the main column 2. The output end of the lifting motor 5 passes through the main column 2 and is fixedly connected to the top of the lead screw 3. When the lifting motor 5 runs, it will cause the lead screw 3 to rotate, thereby improving the adjustment efficiency of the threaded sleeve 4. Slide grooves 6 are opened at both ends inside the main column 2. A slider 7 is movably installed inside the slide groove 6. One end of the slider 7 is fixedly connected to one end of the threaded sleeve 4. When the threaded sleeve 4 slides, it will cause the slider 7 to slide inside the slide groove 6. The sliding of the threaded sleeve 4 is more stable due to the design of the slide groove 6 and the slider 7. An auxiliary column 8 located on the right side of the main column 2 is fixedly installed on the top of the base plate 1. A round rod 9 is fixedly installed inside the auxiliary column 8, and a moving block 10 is movably sleeved on the surface of the round rod 9. The inner surface of the moving block 10 and the outer surface of the round rod 9 are both smooth, which allows the moving block 10 to slide more smoothly on the surface of the round rod 9 and reduces the occurrence of jamming. A connecting rod 11 is fixedly installed between the threaded sleeve 4 and the moving block 10. When the threaded sleeve 4 slides, it will drive the connecting rod 11 to slide, which in turn will drive the moving block 10 to slide. A lifting platform 12 is fixedly installed at one end of the connecting rod 11, and the outer surface of the lifting platform 12 is movably connected to the outer surface of the main column 2 and the auxiliary column 8. When the connecting rod 11 slides, it will drive the lifting platform 12 to slide, so that the position of the lifting platform 12 can be adjusted.

[0021] Four fixing rods 13 are fixedly installed at both ends of the top of the base plate 1. All four fixing rods 13 are of the same size. Each fixing rod 13 has a slot 14 at its top. A threaded rod 15 is rotatably installed inside each slot 14, and a sliding sleeve 16 is threaded onto the surface of each threaded rod 15. When the threaded rod 15 rotates, it causes the sliding sleeve 16 to slide within the slot 14, thus adjusting the position of the sliding sleeve 16. A rotary motor 17 is fixedly installed on one side of each fixing rod 13. The output end of the rotary motor 17 passes through the fixing rod 13 and is fixedly connected to one side of the threaded rod 15. When the rotary motor 17 operates, it causes the threaded rod 15 to rotate, thereby improving the adjustment efficiency of the sliding sleeve 16. A sliding device is fixedly installed on the top of each sliding sleeve 16. When the movable plate 18 and the sliding sleeve 16 slide, they will cause the movable plate 18 to slide. The top of the movable plate 18 is rotatably mounted with a rotating rod 19. The bottom of the rotating rod 19 passes through the movable plate 18 and extends to the bottom of the movable plate 18. The movable plate 18 and the rotating rod 19 are connected by threads. When the movable plate 18 slides, it will cause the rotating rod 19 to slide. The bottom of the rotating rod 19 is fixedly mounted with a support leg 20, and the top of the rotating rod 19 is fixedly mounted with a handle 21. Rotating the handle 21 will cause the rotating rod 19 to slide downward, thereby causing the support leg 20 to slide. The bottom ends of the base plate 1 are movably mounted with four casters 22. The four casters 22 are the same size. Due to the design of the casters 22, the lift can move freely, making it more convenient.

[0022] Working principle: First, the operator moves the lift using the casters 22 until it is positioned on the working ground. Then, the rotary motor 17 is started. The operation of the rotary motor 17 causes the threaded rod 15 to rotate, which in turn causes the sliding sleeve 16 to slide inside the slot 14. At this time, the sliding sleeve 16 causes the moving plate 18 to slide until it extends to both sides of the base plate 1. Then, the handle 21 is turned, which causes the rotating rod 19 to rotate and slide downward inside the moving plate 18. Subsequently, the rotating rod 19 drives the support legs 20 to rotate. Slide the outriggers 20 until they reach the working ground to provide auxiliary support for the elevator. Then start the elevator motor 5. The operation of the elevator motor 5 will cause the lead screw 3 to rotate. The lead screw 3 will then drive the lead sleeve 4 to slide inside the main column 2. Subsequently, the lead sleeve 4 will drive the slider 7 to slide inside the slide groove 6. At this time, the lead sleeve 4 will drive the connecting rod 11 to slide. Subsequently, the connecting rod 11 will drive the moving block 10 to slide inside the auxiliary column 8 and on the surface of the round rod 9. At the same time, the connecting rod 11 will drive the lifting platform 12 to slide, and the lifting operation can be carried out.
