Description

Technical Field

[0001] This utility model relates to the field of pallet lifting technology, specifically a pallet lifting device with protective function. Background Technology

[0002] Pallet lifting devices are commonly used equipment in logistics warehousing, production line handling, and cargo stacking, and are used to achieve vertical lifting and transfer of palletized goods. Traditional pallet lifting devices mostly use simple hoisting structures or fixed guardrails, lacking adjustable protective structures. During the lifting process, goods are easily detached or damaged due to shaking and displacement, especially with poor adaptability to pallets of varying heights or irregularly stacked pallets. Secondly, the fixing methods are limited, mostly using rigid clamps or rope bindings, which are cumbersome to operate and easily damage the edges of the pallets, resulting in low efficiency and safety hazards. Therefore, new technical solutions need to be designed to address these issues. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: In this technical solution, a pallet lifting device with protective function includes a lifting frame 1, a lifting plate 2 installed at the top of the lifting frame 1, a flipping frame installed on one side of the upper end of the lifting frame 1, a compression fixing device installed at the center of the flipping frame, and a flipping driver installed between the flipping frame and the lifting plate 2. The tilting frame includes two hinge seats 3, which are respectively installed on both sides of one end of the lifting frame 1. Two mounting sleeves 4 are hinged to the two hinge seats 3 through shafts. A protective frame 5 is movably embedded in the two mounting sleeves 4. Two positioning holes 6 are machined at the bottom of the protective frame 5. Two fixing ports 7 are opened on both sides of the lower end of the lifting frame 1. Two limiting holes 8 are opened on the side walls of the two fixing ports 7.

[0016] In this technical solution, when lifting the material on the upper part of the pallet, the operator first connects the device to the designated lifting equipment through the lifting plate 2, then connects the device's tilting drive to the power supply, and then moves the lifting frame 1 to the designated position through the lifting equipment, so that the bottom end of the lifting frame 1 is embedded under the pallet to be lifted. Then, the tilting drive is driven, which drives the two mounting sleeves 4 and the protective frame 5 to rotate in the hinge seat 3. The protective frame 5 wraps and protects the material on the upper part of the pallet. Then, the protective frame 5 is pulled down, so that the protective frame 5 moves downward in the two mounting sleeves 4, and the bottom end of the protective frame 5 is embedded in the two fixing sockets 7, so that the two positioning holes 6 at the bottom end of the protective frame 5 correspond to the two limiting holes 8. The protective frame 5 can be fixed for a second time by inserting pins.

[0017] In some technical solutions, reference Figure 1 The extrusion fixture includes an operating frame 9, with both ends of the operating frame 9 fixedly connected to the inner walls of both sides of the protective frame 5. An operating plate 10 is installed inside the operating frame 9. A threaded rod 11 is installed at the center of one side of the operating plate 10 via a bearing. A movable frame 12 is movably fitted onto the upper end of the threaded rod 11. Both ends of the movable frame 12 movably pass through both sides of the operating plate 10. Extrusion plates 13 are installed at both ends of the movable frame 12.

[0018] In this technical solution, after the protective frame 5 is installed, the operator turns the threaded rod 11 on one side of the operating plate 10. With the internal thread of the threaded rod 11 engaging with the internal thread of the moving frame 12, the moving frame 12 can be moved to one side inside the operating plate 10, and push the extrusion plate 13 closer to the material, so as to fully extrude and fix the material, and ensure the overall lifting stability of the material.

[0019] In some technical solutions, reference Figure 1 The flip drive includes a motor 14, which is fixedly installed on the side wall of the lifting plate 2. A first helical gear 15 is installed on the drive end of the motor 14. A second helical gear 16 meshes with one side of the first helical gear 15. An operating shaft 17 is fixedly embedded in the second helical gear 16. The two ends of the operating shaft 17 are respectively connected to the shafts of two hinge seats 3.

[0020] In this technical solution, when the protective frame 5 is flipped, the operator drives the motor 14 to work. The motor 14 drives the first helical gear 15 to rotate. Under the meshing action of the first helical gear 15 and the second helical gear 16, the operating shaft 17 is driven to rotate at a constant speed. Under the connection between the operating shaft 17 and the shaft of the two hinge seats 3, the rotation operation of the two mounting sleeves 4 inside the hinge seats 3 can be realized.

[0021] In some technical solutions, reference Figure 1 The movable frame 12 and the threaded rod 11 are connected by internal threads.

[0022] In this technical solution, the overall movement stability of the moving frame 12 and the extrusion plate 13 is ensured, and the overall position of the moving frame 12 and the extrusion plate 13 is self-locked and fixed.

[0023] In some technical solutions, reference Figure 1 Two lifting rings 18 are installed on both sides of the upper end of the lifting plate 2.

[0024] This technical solution allows for quick connection with lifting equipment and easy integration into existing logistics systems.

[0025] In some technical solutions, reference Figure 1 The movable frame 12 is a U-shaped movable frame 12, and two anti-detachment limit blocks 19 are installed on both sides of the upper end of the protective frame 5.

[0026] In this technical solution, the protective frame 5 is prevented from detaching from the mounting sleeve 4 during the flipping process, thus ensuring the overall installation stability of the protective frame 5.
