Description

Technical Field

[0001] The utility model relates to the field of cargo storage, in particular to cargo storage and loading and unloading equipment. Background Art

[0002] Warehousing is the storage and preservation of goods and articles in warehouses. "Warehouse" is a general term for buildings and places for storing, preserving and storing articles. It can be a house building, cave, large container or specific place, etc., which has the function of storing and protecting articles.

[0003] After searching the patent document with the publication number CN220885640U, the patent document discloses "a loading and unloading device for cargo storage, in which the ratchet is driven to rotate by the first motor, so that the secondary shaft drives the gear C to rotate, the engagement of the pawl with the ratchet can position the ratchet, the gear C drives the meshing gear B to rotate, so that the gear A rotates, and the rotation of the gear A drives the lifting column to rise and fall, thereby completing the cargo loading and unloading, and the two-way threaded rod is driven to rotate by the second motor, so that the two sliders move relative to each other, thereby driving the baffle to move relative to each other, completing the clamping and loosening of the cargo.";

[0004] The warehouse for cargo storage is relatively large, which means that not only one type of cargo may be placed in the warehouse, so the sizes of forklift pallets used to place cargo in the warehouse are also different. The distance between the two plug plates in the above device is fixed, which leads to certain limitations of the above loading and unloading equipment, and it can only be used for specific types of forklift pallets.

A lifting bar 28 is installed at one end of the two sliding frames 23, and the two lifting bars 28 are connected to the two sliding frames 23 through two sets of lifting structures. The two sets of lifting structures include a fixed rod 24, which is fixed inside the sliding frame 23, and a sliding tooth frame 25 is slidably connected to the outer periphery of the fixed rod 24. The lowering bar 28 is fixed to one end of the sliding gear frame 25, a second motor 26 is installed at one end of the sliding frame 23, a gear 27 is fixed on the output shaft of the second motor 26, and teeth are provided at the other end of the sliding gear frame 25, and the teeth on the sliding gear frame 25 mesh with the gear 27. The lower ends of the two lifting bars 28 are fixed with inverted T-shaped strips 29, and the lower ends of the inverted T-shaped strips 29 are installed with rollers, and the upper ends of the inverted T-shaped strips 29 are fixed with multiple stabilizing rods, and one end of the stabilizing rod is fixed to the lifting bar 28, and the upper ends of the inverted T-shaped strips 29 are fixed with multiple limiting rods 210, and both ends of the limiting rods 210 are slidably connected. An extension plate 211 is connected, one end of the extension plate 211 and one end of the inverted T-shaped strip 29 are chamfered, and a plurality of springs 212 are fixed between the two extension plates 211, and two positioning bolts 213 are arranged in the middle of each extension plate 211, and each extension plate 211 is provided with a plurality of through holes corresponding to the two positioning bolts 213, and the inverted T-shaped strip 29 is provided with a plurality of threaded holes corresponding to the positioning bolts 213, and the upper end of the positioning bolt 213 is flush with the upper end surface of the extension plate 211; when the device is in operation, the two sliding frames 23 are connected to the threaded connection of the bidirectional screw 21 and the sliding frame 23 The sliding connection with the fixed frame 2 allows the two sliding frames 23 to move in relative or opposite directions when the first motor 22 drives the bidirectional screw 21 to rotate, so that the spacing between the two inverted T-shaped strips 29 can be adjusted. In this way, the device can be suitable for forklift pallets of various sizes; and the two extension plates 211 on the inverted T-shaped strip 29 are slidably connected to the limit rod 210.

Through the threaded connection between the two sliding frames 23 and the bidirectional screw 21 and the sliding connection between the sliding frame 23 and the fixed frame 2, when the first motor 22 drives the bidirectional screw 21 to rotate, the two sliding frames 23 can move in relative or opposite directions, so that the spacing between the two inverted T-shaped strips 29 can be adjusted. In this way, the device can be applied to forklift pallets of various sizes. Subsequently, the two extension plates 211 on the inverted T-shaped strip 29 are slidably connected with the limit rod 210 to extend the extension plate 2 After the two positioning bolts 213 on 11 are unscrewed, the spacing between the two extension plates 211 can be adjusted, so that the width of the entire plug-in plate structure of the device can be adjusted, so that the applicability of the device is better. After the device is adjusted, the push frame 12 is pushed to make the inverted T-shaped strip 29 of the device and the extension plate 211 extend into the forklift pallet, and then the two second motors 26 are started, and the gear 27 is engaged with the teeth at one end of the sliding tooth frame 25. When the second motor 26 drives the gear 27 to rotate, the sliding tooth frame 25 can be raised and lowered, so that the inverted T-shaped strip 29 drives the goods on the forklift pallet to lift, which is convenient for loading and unloading of the goods.
