Description
Technical Field
[0001] This utility model relates to the field of pallet technology, specifically to a material hoisting device that prevents pallets from falling off. Background Technology
[0002] In modern industrial production and logistics, material handling is a common and crucial process. Pallets, as a frequently used load-bearing and transportation tool, are widely used in the storage, handling, and lifting of various goods. By placing goods on pallets and then using lifting equipment to hoist and move them, efficient transfer of goods can be achieved, greatly improving the efficiency of logistics operations.
[0003] Material hoisting is a crucial step in material handling, and pallets, as a common tool for carrying materials, are of paramount importance for the safety of their hoisting. However, during hoisting, due to the varying shapes, sizes, and weights of goods, existing hoisting devices often struggle to effectively secure goods of different specifications. Furthermore, clamps typically limit the bottom of the goods, resulting in limited limiting area when dealing with taller goods. This makes it difficult to provide stable support, increasing the risk of tilting and tipping, and failing to meet the safe hoisting needs of diverse materials. In addition, conventional lifting rings are only connected to the hook through a simple hook-and-loop method. Before lifting, when the hook is not under the weight of the pallet, it is prone to loosening, causing the lifting ring to accidentally detach from the hook. Therefore, this utility model provides a material hoisting device to prevent pallets from falling. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a material lifting device to prevent pallets from falling. It solves the problem that during lifting, existing lifting devices often struggle to effectively secure goods of varying shapes, sizes, and weights. Furthermore, the clamps typically limit the bottom of the goods, resulting in limited limiting area for taller goods, making it difficult to provide stable support and increasing the risk of tilting or tipping. This fails to meet the safe lifting requirements for diverse materials. Additionally, conventional lifting rings are only connected to the hook via a simple hook-and-loop connection, which can easily loosen before lifting, especially when the hook is not under the weight of the pallet, leading to accidental detachment of the lifting ring from the hook.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a material hoisting device to prevent pallets from falling, comprising a support frame, wherein the support frame is provided with an installation mechanism for hoisting materials in case of pallet drop, the installation mechanism comprising:
[0006] The clamping assembly includes a tray body fixed inside a support frame. The tray body has a clamping plate connected by an opening and closing assembly inside.

[0007] The support assembly includes connecting shafts at four ends of the tray body. A lifting ring is rotatably connected to the outer wall of the connecting shaft. A circular groove is opened inside the lifting ring. A support block connected by an elastic component is arranged inside the circular groove. Limit plates are fixed on both sides of the support block.
[0008] Preferably, a rubber pad is fixed to the bottom of the support frame, and a reinforcing block with a triangular structure is fixed to the lower end of the connection between the inner wall of the support frame and the main body of the tray.
[0009] Preferably, an annular groove is uniformly and through the interior of the tray body, and a rubber ring is fixed at the edge of the upper end face of the annular groove.
[0010] Preferably, the opening and closing assembly includes a sliding groove at the center of the upper end face of the tray body, a bidirectional screw is rotatably connected inside the sliding groove, a guide groove is provided on the inner wall of the support frame, the two ends of the clamp are slidably connected to the inner wall of the guide groove, the clamp is configured as two sets, the clamp is threadedly connected to the bidirectional screw, and rubber rods are evenly distributed on the inner wall of the clamp.
[0011] Preferably, the locking assembly includes an adjusting rod with a support shaft extending to one end of the cavity groove and fixed thereon. A bolt is provided on one side of the adjusting rod, and a pair of threaded holes are provided on the side wall of the clamping plate. The bolt is threadedly connected to the threaded holes.
[0012] Preferably, the elastic component includes a spring fixed to the bottom of the circular slot, a support block fixedly connected to the other end of the spring, and a telescopic sleeve provided on the inner ring of the spring, with both ends of the telescopic sleeve fixedly connected to the support block and the bottom of the circular slot, respectively.
[0013] Beneficial effects
[0014] This utility model provides a material lifting device to prevent pallets from falling off. Compared with the prior art, it has the following advantages:
[0015] Firstly, this utility model, by setting up a clamping assembly, uses a bidirectional screw to drive two sets of clamping plates to move, which can flexibly limit and clamp materials according to their size. The rubber rods on the inner walls of the clamping plates increase the friction with the materials, further preventing the materials from slipping and falling. This also enhances the support and limiting area of the clamping plates, avoiding the limitation of the clamping plate's limiting area when the goods are high. When the material is high and the clamping plate's limiting area is limited, rotating the adjusting rod causes the supporting shaft to rotate within the cavity groove. The supporting shaft then drives the supporting rod fixed on the outer wall to rotate, allowing the supporting rod to rotate to a suitable position to limit the goods loaded on the pallet body from both sides, thus enhancing the support and limiting area of the clamping plates. Finally, bolts are screwed into the corresponding threaded holes opened on the side walls of the clamping plates to fix the adjusting rod, thereby fixing the position of the supporting rod and ensuring the stability of the goods.
[0016] Secondly, when the hook and the lifting ring are suspended, the hook is inserted into the lifting ring. At this time, the hook presses against the support block, the support block compresses the spring, moves down along the telescopic sleeve guide and embeds into the round hole groove. After the hook is fully inserted, the spring rebounds and pushes the support block to reset, supporting the hook from the inside. The limiting plate prevents the support block from dislodging from the round hole groove, realizing a stable connection between the lifting ring and the hook for material lifting. The hook automatically locks after being embedded, and the limiting plate prevents it from falling off. Compared with conventional lifting rings, this significantly reduces the risk of the hook falling off during lifting, ensures lifting safety, and prevents the hook from loosening before lifting because it is not subjected to the weight of the pallet body.

[0022] 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.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a material hoisting device to prevent pallets from falling, including a support frame 1, on which an installation mechanism for hoisting materials in case of pallet drop is provided, the installation mechanism including:
[0024] The clamping assembly includes a tray body 2 fixed inside the support frame 1. The tray body 2 has a clamping plate 204 connected by an opening and closing assembly inside. The clamping plate 204 has a cavity groove 3 inside. A support shaft 301 is rotatably connected inside the cavity groove 3. A support rod 302 is fixed to the outer wall of the support shaft 301. A locking assembly for fixing is provided at one end of the support shaft 301 extending to the outside of the cavity groove 3.
[0025] The support assembly includes a connecting shaft 4 at each of the four ends of the tray body 2. A lifting ring 401 is rotatably connected to the outer wall of the connecting shaft 4. A circular groove 402 is provided inside the lifting ring 401. A support block 405 connected by an elastic component is provided inside the circular groove 402. Limiting plates 406 are fixed on both sides of the support block 405.
[0026] In a preferred embodiment, a rubber pad 502 is fixed to the bottom of the support frame 1, and a reinforcing block 503 with a triangular structure is fixed to the lower end of the connection between the inner wall of the support frame 1 and the pallet body 2. When the material to be hoisted is placed on the pallet body 2, the pallet body 2 is in a fixed position inside the support frame 1. The rubber pad 502 at the bottom of the support frame 1 can play a certain role in buffering and stabilizing. The reinforcing block 503 at the lower end of the connection between the inner wall of the support frame 1 and the pallet body 2 enhances the connection strength.
[0027] Among them, the triangular reinforcing block 503, which is fixed at the lower end of the connection between the inner wall of the support frame 1 and the pallet body 2, enhances the connection strength between the support frame 1 and the pallet body 2 by utilizing the principle of triangular stability.
[0028] In a preferred embodiment, an annular groove 5 is uniformly provided throughout the interior of the pallet body 2. A rubber ring 501 is fixed at the upper edge of the annular groove 5. The annular groove 5 inside the pallet body 2 and the rubber ring 501 at the upper edge can play a certain anti-slip role on the bottom of the material, and the annular groove 5 reduces the weight of the pallet body 2.
[0029] Furthermore, the rubber pad 502 fixed at the bottom of the support frame 1 plays a buffering role during material placement and hoisting, reducing the impact of vibration on the device, while increasing the friction between the device and the ground, making the device more stable.
[0030] In a preferred embodiment, the opening and closing assembly includes a groove 201 formed at the center of the upper end face of the pallet body 2. A bidirectional screw 202 is rotatably connected inside the groove 201. A guide groove 203 is formed on the inner wall of the support frame 1. The two ends of the clamping plate 204 are slidably connected to the inner wall of the guide groove 203. The clamping plate 204 is configured as two sets. The clamping plate 204 is threadedly connected to the bidirectional screw 202. Rubber rods 205 are evenly distributed on the inner wall of the clamping plate 204. The clamping plate 204 limits and clamps the material on the pallet body 2. When the bidirectional screw 202 is rotated, the clamping plate 204 and the bidirectional screw 202 are slidably connected to the support frame 1. The screw 202 is threaded to the clamping plate 204, and the two ends of the clamping plate 204 slide along the guide groove 203. The two sets of clamping plates 204 will move closer and further away from each other along the slide groove 201. After the material is placed on the pallet body 2, the double screw 202 is adjusted to make the clamping plate 204 closer to the material. The rubber rod 205 is used to elastically contact and limit the clamping of the material. By setting the clamping component, the double screw 202 drives the two sets of clamping plates 204 to move, and the material can be flexibly limited and clamped according to the size of the material. The rubber rod 205 on the inner wall of the clamping plate 204 increases the friction with the material, further preventing the material from sliding and falling.
[0031] In a preferred embodiment, the locking assembly includes an adjusting rod 303 extending from a support shaft 301 to one end fixed to the outside of the cavity groove 3. A bolt 304 is provided on one side of the adjusting rod 303. A pair of threaded holes 305 are provided on the side wall of the clamping plate 204. The bolt 304 is threadedly connected to the threaded holes 305. The support rod 302 is used to limit the goods loaded on the pallet body 2 on both sides, enhance the support and limiting area of the clamping plate 204, and avoid the limited limiting area of the clamping plate 204 when the goods are high. When the limiting area of the clamping plate 204 is limited, the adjusting rod 303 is rotated. The adjusting rod 303 drives the support shaft 301 to rotate in the cavity groove 3. The support shaft 301 drives the support rod 302 fixed on the outer wall to rotate, so that the support rod 302 rotates to a suitable position to limit the goods loaded on the pallet body 2 on both sides, thereby increasing the supporting limiting area of the clamping plate 204. Then, the bolt 304 is screwed into the corresponding threaded hole 305 opened on the side wall of the clamping plate 204 to fix the adjusting rod 303, thereby fixing the position of the support rod 302.
[0032] The threaded holes 305 are provided in two sets, with an included angle of 90° between them, which are used to rotate the support rod 302 to the vertical direction.
[0033] In a preferred embodiment, the elastic component includes a spring 403 fixed to the bottom of the circular slot 402, a support block 405 fixedly connected to the other end of the spring 403, and a telescopic sleeve 404 provided on the inner ring of the spring 403. The two ends of the telescopic sleeve 404 are fixedly connected to the support block 405 and the bottom end of the circular slot 402, respectively. The lifting hook engages with the lifting ring 401. When the hook and lifting ring 401 are suspended, the hook is inserted into the lifting ring 401, which presses against the support block 405. The support block 405 compresses the spring 403 and the telescopic sleeve... The rod 404 is guided downward and embedded in the circular slot 402. After the hook is fully inserted, the spring 403 rebounds and pushes the support block 405 to reset, supporting the hook from the inside. The limiting plate 406 prevents the support block 405 from disengaging from the circular slot 402, thus achieving a stable connection between the lifting ring 401 and the hook for material lifting. The hook automatically locks after being embedded, and the limiting plate 406 prevents it from detaching. Compared with the conventional lifting ring 401, this significantly reduces the risk of the hook falling off during lifting, ensuring lifting safety and preventing the hook from loosening before lifting because it is not subjected to the gravity of the pallet body 2.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] During operation, the material to be hoisted is first placed on the pallet body 2. The pallet body 2 is fixed inside the support frame 1. The rubber pad 502 at the bottom of the support frame 1 serves to buffer, stabilize, and increase friction. The triangular reinforcing block 503 at the lower end of the connection between the support frame 1 and the pallet body 2 enhances the connection strength through the stability of the triangle. The annular groove 5 on the pallet body 2 reduces its own weight, and the rubber ring 501 on the upper edge of the surface prevents the bottom of the material from slipping.
[0036] Next, rotate the bidirectional screw 202. Since the clamping plate 204 is threadedly connected to the bidirectional screw 202 and both ends slide along the guide groove 203, the two sets of clamping plates 204 move closer or further away from each other along the slide groove 201. After the material is placed, adjust the bidirectional screw 202 so that the clamping plate 204 can elastically contact and limit the material with the help of the inner wall rubber rod 205, which can flexibly adapt to materials of different sizes and increase friction to prevent them from falling.
[0037] If the material is too high and the limiting area of the clamping plate 204 is insufficient, rotate the adjusting rod 303 to drive the support shaft 301 to rotate in the cavity groove 3, so that the support rod 302 rotates out to limit the two sides of the goods, thereby increasing the support area. Then screw the bolt 304 into the corresponding threaded hole 305 to fix the position of the adjusting rod 303 and the support rod 302.
[0038] Finally, the lifting hook and lifting ring 401 cooperate. When the hook is inserted into the lifting ring 401, it squeezes the support block 405. The support block 405 compresses the spring 403 and moves down along the telescopic sleeve 404 to embed into the round hole groove 402. After insertion, the spring 403 rebounds and pushes the support block 405 to reset and support the hook from the inside. The limiting plate 406 prevents the support block 405 from detaching, thus achieving stable connection and lifting, reducing the risk of hook falling off, avoiding loosening before lifting, and completing the material lifting operation.
