Description

Technical Field

[0001] This utility model relates to the field of warehouse lifting equipment technology, and more specifically, to a safety lifting device for storing large goods. Background Technology

[0002] A crane is a specialized crane that uses forks as a lifting device to move, stack, or pick up unit goods from high-rise shelves in warehouses, workshops, etc. It mainly includes wire rope type and hydraulic cylinder type. When storing large items in a warehouse, lifting devices are needed to lift and raise the heavy items in order to complete the storage work.

[0003] However, existing technologies offer a variety of lifting devices. For example, utility model patent CN218879371U relates to a warehouse stacker crane. This utility model includes a bridge frame with end beams at both ends. A trolley traveling mechanism is mounted on the end beams, and the trolley traveling mechanism is mounted on a trolley traveling track. A trolley is mounted on the bridge frame, and an upper support frame is located below the trolley. A slewing support is mounted at the lower end of the upper support frame. An electric hoist is detachably fixed to the upper support frame. A vertically arranged lower support frame is located below the upper support frame and is rotatably mounted on the upper support frame via the slewing support. The lower support frame has a vertically arranged slide rail. A fork tooth fixing frame is located below the slewing support and is slidably mounted within the slide rail on the lower support frame. Several guide wheels are provided between the fork tooth fixing frame and the lower support frame. The top of the fork tooth fixing frame is connected to the electric hoist via a chain, and stacking forks for moving heavy objects are fixed on the fork tooth fixing frame. This utility model has a simple structure and is easy to use.

[0004] Although this lifting device is convenient to use and can efficiently lift and move heavy goods, it lacks a direct and effective fixing mechanism because it supports heavy objects through stacking forks. This makes it easy for heavy objects to slip during the lifting process and fall directly off the device, posing a safety hazard and damaging the goods. Therefore, it is not practical. To avoid this, it is essential to design a safe lifting device for storing large goods. Utility Model Content

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 as well as Figure 2The diagram shows the structure of the safety lifting device for large cargo storage in this embodiment. The lifting device includes a mounting frame 1. Two symmetrical support slide rods 2 are fixedly connected within the mounting frame 1. A movable plate 3 is slidably mounted on the support slide rods 2. A fixed frame 4 is located at the bottom of the movable plate 3, and the fixed frame 4 is U-shaped. A movable seat 5 is vertically mounted within the fixed frame 4. A bearing plate 6 is fixed to the movable seat 5. Multiple guide rods 7 are slidably mounted within the bearing plate 6. Two extension platforms 8 are fixedly connected to the ends of the guide rods 7 that are far apart from each other. The two extension platforms 8 are symmetrically arranged, and a clamping plate 9 is fixedly connected to the top of each extension platform 8. The tops of the support plate 6 and the extension platform 8 are on the same plane. Two symmetrical electric push rods are installed inside the support plate 6. The output end of the electric push rod is fixed to one end of one of the guide rods 7. When lifting large items on the device, the large items are placed on the support plate 6, so that the items are located between the two clamping plates 9. At the same time, according to the specific size of different items, the electric push rods are activated, and the output end of the electric push rods is controlled to push the guide rod 7 to slide, so that multiple guide rods 7 extend and retract, bringing the two symmetrical extension platforms 8 closer to each other or further away, driving the two clamping plates 9 to press the items, and the large items are initially clamped and fixed by the clamping plates 9.

[0028] like Figure 3 As shown, this is a structural schematic diagram of the tightening component in this embodiment. In this embodiment, two symmetrical fixing buckles 10 are set on the top of the movable seat 5 on the support plate 6, and a tightening box 11 is set thereon. A rotating shaft 12 is rotatably connected inside the tightening box 11 through a bearing. Two symmetrical binding straps 13 are fixedly connected to the surface of the rotating shaft 12. One end of each binding strap 13 is fixed with a hook 14, and the hook 14 can be hooked onto the fixing buckle 10. After the large goods are clamped and fixed on the support plate 6, the binding straps 13 are pulled out from the tightening box 11 through the rotating shaft 12, and the two binding straps 13 are wrapped around the large goods once, and the two hooks 14 are hooked onto the fixing buckle 10 respectively. The binding straps 13 are used to further tighten the clamped large goods, thereby providing stable support for the large goods and preventing the heavy objects from slipping and falling directly off the device during the lifting process. This improves the safety of the lifting device in use and is less likely to damage the goods, making it highly practical.

[0029] It is also worth noting that, such as Figure 4As shown, in this embodiment, a crank handle 15 is fixedly connected to one end of the rotating shaft 12. A positioning plate 16 is coaxially arranged on the surface of the rotating shaft 12, and the positioning plate 16 is located inside the tightening box 11. The positioning plate 16 is provided with multiple positioning holes 17 at equal intervals. A threaded sleeve 18 is provided on one side of the tightening box 11. A limit pin 19 is threadedly connected inside the threaded sleeve 18. The end of the limit pin 19 can pass through any matching positioning hole 17. When the restraint strap 13 is wrapped around the goods and hung on the fixing buckle 10, the crank handle 15 is turned by hand to drive the rotating shaft 12 to rotate, so that the excessively long restraint strap 13 is slowly wound onto the rotating shaft 12, gradually tightening the restraint strap 13 to further secure the large goods. At this time, by using the threaded engagement between the threaded sleeve 18 and the limit pin 19, the adjusting plate is turned so that the adjusting plate drives the limit pin 19 to pass through the corresponding positioning hole 17. The positioning plate 16 is tightened by the fixed limit pin 19, so that the restraint strap 13 is in a taut state.

[0030] like Figure 6 As shown, this is a schematic diagram of the sliding structure of the movable plate 3 within the mounting frame 1 in this embodiment. In this embodiment, a mounting bracket 26 is fixedly connected to the top of the mounting frame 1, and the mounting bracket 26 is inverted U-shaped. A rack 27 is provided on the inner wall of the mounting bracket 26. Two symmetrical fixed plates 28 are provided on the upper surface of the movable plate 3. A transmission gear 30 is rotatably connected between the fixed plates 28 through a rotating shaft, and the transmission gear 30 is meshed with the rack 27. A rotary motor 29 is fixed on the movable plate 3, and the output end of the rotary motor 29 is fixed to one end of the rotating shaft. After the large goods are fixed on the bearing plate 6, the rotary motor 29 is started to provide driving force to the rotating transmission gear 30. At the same time, by utilizing the cooperation between the transmission gear 30 and the rack 27, the rotating transmission gear 30 can roll on the rack 27, thereby driving the movable plate 3 to slide horizontally on the support slide rod 2, and horizontally transporting the large goods.

[0031] like Figure 5As shown, this is a cross-sectional view of the fixing frame 4 in this embodiment. In this embodiment, two symmetrical support plates are fixedly connected to the fixing frame 4. A first drive shaft 20 is rotatably connected between the two support plates via bearings. Two symmetrical storage coils 22 are sleeved on the surface of the first drive shaft 20. A traction rope 23 can be wound inside the storage coils 22. A servo motor 21 is installed on one side of the support plate, and the output end of the servo motor 21 is fixed to one end of the first drive shaft 20. A second drive shaft 24 is rotatably connected to the fixing frame 4 via bearings. Two symmetrical guide rollers 25 are fitted on the surface of 4. One end of the traction rope 23 can be wrapped around the guide rollers 25 and fixedly connected to the movable seat 5. During the lifting of fixed large goods, the servo motor 21 provides driving force to the rotation of the first drive shaft 20, so that the first drive shaft 20 drives the two storage coils 22 to rotate, and the traction rope 23 is wound in the storage coils 22. At the same time, with the transmission action of the guide rollers 25, the traction rope 23 drives the movable seat 5 to rise and fall through the guidance of the guide rollers 25, so as to complete the lifting operation.

[0032] It is worth noting that in this embodiment, a guide groove 31 is provided in the fixed frame 4, and sliders 32 are fixed on both sides of the movable seat 5. The sliders 32 and the guide groove 31 are slidably installed. By utilizing the cooperation between the sliders 32 and the guide groove 31, the movable seat 5 can be stably moved up and down in the fixed frame 4.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
