Description

Technical Field

[0002] Warehousing is the storage and management of goods in warehouses. It is also a very important part of the commodity circulation and production process. Goods are shipped out of and stored in warehouses every moment. During the loading and warehousing process, the goods need to be lifted and lowered due to the height difference. For this reason, a cargo lifting device for warehousing came into being. The traditional cargo lifting device has poor stability during lifting. The goods are easily shaken due to inertia, resulting in reduced safety. It cannot fix the loaded goods and has poor operability.

[0003] For example, a cargo lifting device for warehousing disclosed in a Chinese patent document (publication number: CN214780484U) is disclosed. Although this patent pulls the clamping plate to both sides by pulling the moving rod, and the stabilizing cylinder can stabilize the moving rod, after the cargo to be lifted is loaded into the loading slot, the moving rod can be released and the clamping plate can be pushed by the elastic force of the compression spring to clamp and fix the cargo, so that the cargo is more stable inside the loading slot. However, the two moving rods are located on both sides of the loading slot, which results in two workers pulling the moving rods when placing the cargo, and then other workers place the cargo in the loading slot, which makes the fixing of the cargo more complicated, and after the cargo is lifted to the specified height, it needs to be unloaded manually. Since the loading slot is in a suspended state, manual unloading is not only labor-intensive, but also prone to safety hazards. Utility Model Content

[0024] A fixing device is provided on one side surface of the movable plate 7 , and the fixing device includes a reset rod 8 , one end of the reset rod 8 is fixedly connected to one side surface of the movable plate 7 .

[0025] The two side surfaces of the lifting shell 6 are fixedly installed with symmetrically distributed servo electric cylinders 81, one end of the piston rod of the servo electric cylinder 81 contacts with one side surface of the movable plate 7, the other end of the reset rod 8 penetrates and extends to the interior of the lifting shell 6, one end of the reset rod 8 is fixedly connected with a clamping block 82, and the outer surface of the reset rod 8 is movably sleeved with a reset spring 83. The elastic force of the reset spring 83 drives the clamping block 82 to move through the reset rod 8, clamps and positions the goods, and through the elastic clamping, it avoids damage to the goods due to excessive force. One end of the reset spring 83 is in contact with the inner wall of one side of the lifting shell 6 Fixedly connected, the other end of the reset spring 83 is fixedly connected to one side surface of the clamping block 82, and symmetrically distributed travel grooves 84 are provided on both side surfaces of the lifting shell 6. Symmetrically distributed mounting blocks 85 are fixedly connected to both side surfaces of the lifting shell 6. A servo motor 86 is fixedly installed on the back of the mounting block 85. A screw rod 87 is fixedly installed on the output shaft of the servo motor 86 through a coupling. One end of the screw rod 87 passes through and extends to the front of the mounting block 85. A positioning block 88 is installed on the outer surface of one end of the screw rod 87 through a bearing. The positioning block 88 improves the stability of the screw rod 87 during rotation through the cooperation of the bearing.

[0026] One side surface of the positioning block 88 is fixedly connected to one side surface of the lifting shell 6, and the outer surface of the screw rod 87 is threadedly connected to the threaded block 89. The clockwise and counterclockwise rotation of the screw rod 87 drives the threaded block 89 to move back and forth. One side surface of the threaded block 89 is fixedly connected to a travel block 810. One end of the travel block 810 passes through the travel groove 84 and extends to the interior of the lifting shell 6. The travel groove 84 guides and limits the movement of the travel block 810.

The winding of the steel wire rope 814 drives the lifting block 815 to move upward through the guide wheel 3, and the movement of the lifting block 815 drives the goods in the lifting shell 6 to move upward through the connecting rod 816.

[0027] By setting up a fixing device, it is convenient to fix the hoisted goods, thereby improving the stability during lifting. After lifting to the specified height, automatic unloading not only reduces manual labor but also avoids the safety hazards caused by manual unloading.

[0028] Working principle: Step 1, when lifting the goods, first start the servo electric cylinder 81 piston rod to extend the movement, the extension of the piston rod squeezes the movable plate 7, so that the movable plate 7 drives the clamping block 82 to move through the reset rod 8, at this time the reset spring 83 contracts, and then the goods to be lifted are placed inside the lifting shell 6, and the servo electric cylinder 81 piston rod is started to retract, when the piston rod cancels the squeezing of the movable plate 7, the reset elastic force of the reset spring 83 drives the reset rod 8 to move through the movable plate 7, so that the two sides of the goods are clamped and positioned by the clamping block 82;

[0029] Step 2: At this time, the cargo is moved by the mobile base 1. When the cargo is moved to the unloading location, the winch body 813 is started to drive the wire rope 814 to be wound. The winding of the wire rope 814 drives the lifting block 815 to move upward through the guidance of the guide wheel 3. The upward movement of the lifting block 815 drives the lifting shell 6 to move upward through the connecting rod 816. The upward movement of the lifting shell 6 is stably moved through the cooperation of the guide slide 4 and the guide slide rod 5, thereby preventing the cargo from shaking.

[0030] Step three, when it rises to the specified height, stop the winch body 813, first start the servo electric cylinder 81 piston rod to extend, the extension of the piston rod squeezes the movable plate 7, so that the movable plate 7 drives the clamping block 82 to move through the reset rod 8, so that the cargo is out of the limit, and then start the servo motor 86 to drive the screw rod 87 to rotate clockwise, the rotation of the screw rod 87 drives the threaded block 89 to move, the movement of the threaded block 89 drives the travel block 810 to move stably through the cooperation of the travel groove 84, the movement of the travel block 810 drives the push plate 811 to move, and the movement of the push plate 811 pushes the cargo inside the lifting shell 6 to the unloading platform.
