Description

Technical Field

[0001] This utility model relates to the field of lifting platforms, specifically to an inverted lifting type lifting platform. Background Technology

[0002] In industrial production, warehousing and logistics, and construction, lifting platforms are key equipment for vertical transportation of goods or high-altitude operations, and their performance directly affects operational efficiency and safety. Traditional lifting platforms often employ scissor-type or telescopic-type structural designs; however, these designs have several limitations in practical applications: the maximum lifting height of traditional lifting platforms is often fixed, making it impossible to flexibly adjust to the needs of different work scenarios. If multiple heights are required, different specifications of lifting platforms must be replaced, increasing equipment investment costs and operational complexity. Furthermore, some lifting platforms are prone to instability during lifting, such as swaying and shifting, especially when carrying heavy loads, where stability issues become more pronounced, affecting operational accuracy and posing safety hazards. Therefore, those skilled in the art have provided an inverted lifting platform to address the problems mentioned in the background section. Utility Model Content

The base plate is symmetrically equipped with four grooved rods. The inner wall of the grooved rods is provided with positioning holes. Two grooved rods are slidably connected to a moving block. A fixing rod is installed on the upper end of the moving block. A fixing block is installed on the upper side of the fixing rod. Limiting grooves are provided at both ends of the moving block and the fixing rod. The limiting grooves pass through the lower end of the moving block. A positioning mechanism is symmetrically arranged inside the moving block.

[0004] A platform is set on the upper side of the base plate, and mating plates are installed at the left and right ends of the platform. The mating plates are sleeved on the grooved rod and the fixing rod. Retracting and extending wheels are symmetrically set at the lower end of the platform. Limiting wheel sets are symmetrically installed at the lower end of the platform. Maturing wheels are symmetrically installed at the lower end of the platform. Pull ropes are wrapped around the outer surface of the retracting and extending wheels, and the pull ropes pass through the limiting wheel sets, mating wheels and notches in sequence to fix the fixing blocks.

[0005] Preferably, the positioning mechanism includes a slide groove and a positioning block. The slide groove is located at the lower end of the moving block. A latching block is slidably connected inside the slide groove. The positioning block is installed at the outer end of the latching block, and the positioning block corresponds to the position of the positioning hole.

[0006] Preferably, a threaded groove is formed at the top of the chute, an extrusion block is provided inside the chute, and a fastening bolt is provided inside the extrusion block.

[0007] Preferably, the mating plate has symmetrical square holes inside, and the mating plate is fitted onto the outside of the grooved rod through the square holes. A connecting hole is formed between the two square holes, and the mating plate is fitted onto the outside of the fixing rod through the connecting hole.

[0008] Preferably, the connecting hole has symmetrically installed limiting blocks on its inner wall, and the limiting blocks are located in the limiting groove, with a notch opened at the end of the mating plate near the platform.

[0009] Preferably, a bevel gear one is installed at the rear end of the take-up and release wheel, a transmission rod is set at the lower end of the platform, a bevel gear two is symmetrically installed on the outer surface of the transmission rod, and the bevel gear two and the bevel gear one mesh, a reducer is installed at one end of the transmission rod, and a motor is installed at one end of the reducer.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model allows the sliding of the movable block within the grooved rod to adjust the height of the fixed rod and the fixed block, thereby flexibly setting the maximum lifting height of the platform. Compared to the fixed height design of traditional lifting platforms, this design can be quickly adjusted according to different work scenarios without the need to replace equipment, significantly reducing equipment investment costs, improving the adaptability of the equipment in multiple scenarios, and enhancing operational flexibility.

[0012] 2. When the platform rises, the mating plate moves outside the grooved rod and the fixed rod through the square hole and the connecting hole, respectively. At the same time, the limiting block slides synchronously in the limiting groove to form a limiting and guiding structure, which effectively limits the lateral swaying and deviation of the platform during the lifting process. In addition, the rope drive ensures that the pulling force is evenly transmitted through the coordinated action of the take-up and release wheel, the limiting wheel group and the mating wheel, further avoiding platform bumps.

Two grooved rods 2 are slidably connected to a moving block 4. A fixing rod 5 is installed on the upper end of the moving block 4, and a fixing block 6 is installed on the upper side of the fixing rod 5. Limiting grooves 7 are formed at both ends of the moving block 4 and the fixing rod 5, and the limiting grooves 7 penetrate the lower end of the moving block 4. A positioning mechanism 8 is symmetrically arranged inside the moving block 4. The positioning mechanism 8 includes... The slide 9 and positioning block 11 are provided. The slide 9 is located at the lower end of the moving block 4. A latching block 10 is slidably connected inside the slide 9. The positioning block 11 is installed at the outer end of the latching block 10, and the positioning block 11 corresponds to the position of the positioning hole 3. A threaded groove 12 is provided at the top of the slide 9. A pressing block 13 is provided inside the slide 9. A fastening bolt 14 is provided inside the pressing block 13. A platform 15 is provided on the upper side of the base plate 1. Four support legs 16 are installed at the lower end of the platform 15. Mating plates 17 are installed at the left and right ends of the platform 15, and the mating plates 17 are fitted onto the base plate 4. Outside the grooved rod 2 and the fixing rod 5, square holes 18 are symmetrically opened inside the mating plate 17, and the mating plate 17 is sleeved on the outside of the grooved rod 2 through the square holes 18. A connecting hole 19 is opened between the two square holes 18, and the mating plate 17 is sleeved on the outside of the fixing rod 5 through the connecting hole 19. Limiting blocks 20 are symmetrically installed on the inner wall of the connecting hole 19, and the limiting blocks 20 are located in the limiting groove 7. A notch 21 is opened at the end of the mating plate 17 near the platform 15. Retracting wheels 22 are symmetrically arranged at the lower end of the platform 15. Limiting blocks 20 are symmetrically installed at the lower end of the platform 15. The platform 15 has a set of 23 gears and a set of 24 gears symmetrically mounted on the lower end of the platform. The outer surface of the take-up and release wheel 22 is wrapped with a pull rope 25, which passes through the set of 23 gears, the set of 24 gears and the notch 21 in sequence and is fixedly connected to the fixing block 6. The rear end of the take-up and release wheel 22 is equipped with a bevel gear 26.

Then, the fastening bolt 14 is screwed into the threaded groove 12, so that the pressing block 13 is fixed in the sliding groove 9 and abuts against the buckle block 10, thereby fixing the position of the positioning block 11.

[0026] Motor 30 drives transmission rod 27 to rotate via reducer 29. Transmission rod 27 drives take-up and release wheel 22 to rotate via bevel gear 28 and bevel gear 26. The rotation of take-up and release wheel 22 winds the pull rope 25. The pull rope 25 pulls the fixing block 6, causing platform 15 and mating plate 17 to rise. The mating plate 17 moves outside the groove rod 2 and fixing rod 5 through square hole 18 and connecting hole 19. At the same time, limit block 20 moves within limit groove 7, causing platform 15 to rise stably.
