Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a segmented assembly type brick hoisting cage. Background Technology

[0002] Existing modular lifting cages, often assembled in sections, employ a modular design for ease of transportation and storage. However, their connection method is generally bolt fastening, which presents inherent safety hazards in practical applications. During lifting operations, the starting, stopping, raising, lowering, and swaying of the cage generate continuous dynamic impact loads and vibrations. These loads act on the bolted connection nodes, easily causing minute relative displacements between the connection surfaces. Over time, this accumulation leads to a decrease in bolt preload and loosening of nuts. Once the connection loosens, the overall structural rigidity of the cage will significantly decrease, affecting not only lifting stability but, more seriously, potentially causing structural failure and posing a significant threat to construction safety. Utility Model Content

[0003] This utility model provides a segmented assembly type brick hoisting cage, the purpose of which is to solve the technical problem that the segmented assembly type hoisting cage has poor connection reliability and safety hazards under dynamic load in the prior art.

[0004] This utility model provides a segmented, assembled brick-lifting cage, comprising: A base, wherein a first pin hole is provided at one of the corners of the base; The support structure includes two opposing support side plates and a support back plate fixedly connected between the support side plates; the bottom of the support side plates and the support back plate are engaged with the edge of the base, and a second pin hole corresponding to the first pin hole is provided at the connection between the support side plates and the support back plate. A pin is inserted into a first pin hole and a second pin hole that are aligned with each other. The top of the pin is provided with a hanging ring for lifting, and the bottom of the pin is fixedly connected to the base.

[0005] Furthermore, a limiting frustum is formed at the bottom of the pin shaft, and the first pin hole on the base is a frustum-shaped pin hole that matches the limiting frustum. The side surface of the limiting frustum abuts against the inner wall of the frustum-shaped pin hole.

[0006] Furthermore, a first support tube is fixedly connected to the vertical edge of the support side plate away from the support back plate. A second support tube and a third support tube are fixedly connected to the vertical edge where the support side plate and the support back plate connect. The second and third support tubes are staggered and coaxially arranged and abut against each other in sequence, so that the pin passes through the third and second support tubes in sequence at intervals. The second pin hole is opened in the first, second, and third support tubes. The support side plate and the support back plate are fixedly connected by pins passing through the second pin holes.

[0007] Furthermore, a first limiting groove is provided at the edge of the upper surface of the base to accommodate the bottom of the supporting side plate and the supporting back plate; a limiting block is fixedly connected to the bottom of the supporting side plate and the supporting back plate, and a second limiting groove is provided in the first limiting groove to cooperate with the limiting block.

[0008] Furthermore, the supporting side plate and the supporting back plate are truss plates.

[0009] Furthermore, the support structure also includes a door panel, and L-shaped grooves are respectively provided on the support side panels, and the door panel is slidably installed in the grooves.

[0010] This utility model has at least the following beneficial effects: This invention provides a segmented, assembled brick-lifting cage. When the cage is lifted via the hanging ring at the top of the pin, the weight of the cage and the bricks themselves is converted into a strong pulling force on the pin. This pulling force firmly holds the base and each support plate together; the greater the load, the stronger the locking force. This dynamic self-locking characteristic is the opposite of traditional bolted connections, which are prone to loosening under vibration and load, thus eliminating the risk of loosening and ensuring structural stability and safety during lifting.

[0011] This invention provides a segmented, assembled brick-lifting cage, with a pin serving as a rigid connector, penetrating the base and support plate to form a stable structural node. Compared to bolt connections, which are prone to minor gaps, the pin connection provides a more direct force transmission path, effectively resisting shear and bending deformation, resulting in an assembled cage with rigidity and stability approaching that of a fully welded structure.

[0013] 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.

[0014] Please see Figure 1-6 This utility model provides a segmented assembly type brick hanging cage, including a base 1, a support structure and a limiting structure. The support structure includes two support side plates 2, a support back plate 3 and a door panel 16 fixedly connected to the upper surface of the base 1. The limiting structure is fixedly connected to the base 1, the support side plates 2 and the support back plate 3. The support side plates 2 are nested with each other at their edges and fixedly connected by the limiting structure.

[0015] The base 1 has first pin holes 4 at its four corners, and the nested support side plates 2 and the edges of the support side plates 2 have second pin holes 5. The first pin holes and the second pin holes 5 are connected. Pins 12 are threaded through the first pin holes 4 and the second pin holes 5. The bottom of the pins 12 abuts against the bottom of the base 1. A hanging ring 7 is fixedly connected to the top of the pins 12.

[0016] In an embodiment of this utility model, the bottom of the pin 12 is a limiting frustum 6, and the first pin hole of the limiting frustum 6 is a frustum-shaped pin hole. The side surface of the limiting frustum 6 abuts against the inner wall of the first pin hole. When the lifting mechanism raises the hanging ring, the pin 12, under gravity, will further tighten the base 1, the supporting side plate 2, and the supporting back plate 3. When the pin 12 is pulled upward, the conical limiting frustum 6 will tightly wed into the corresponding frustum-shaped pin hole on the base 1. This not only provides strong vertical locking, effectively preventing the support plate from floating or shifting relative to the base 1, but also further eliminates potential gaps at the connection, making the connection between the base 1 and the support structure more stable and reliable. Especially in dealing with the impact load during start-up and shutdown, its impact resistance and vibration resistance are significantly enhanced.

[0017] In an embodiment of this utility model, a first support tube 9 is provided on the side of the support side plate 2 facing the door panel 16, and the second pin hole 5 is provided in the first support tube 9. The height of the first support tube 9 is equal to the height of the support side plate 2.

[0018] In this embodiment of the invention, a plurality of second support tubes 10 are provided at one end of the support side plate 2 facing the support back plate 3, and a plurality of third support tubes 11 are provided on both sides of the support back plate 3. The third support tubes 11 are staggered with the second support tubes 10. The second support tubes 10 on one side of the support side plate 2 are vertically spaced apart, and the third support tubes 11 on one side of the support back plate 3 are vertically spaced apart. When the support side plate 2 and the support back plate 3 are respectively fitted together, the second support tubes 10 and third support tubes 11 with overlapping vertical projections have second pin holes at their centers. When the pin shaft 12 is inserted into the support tube, a composite column composed of multiple layers of tube walls and the pin shaft 12 is actually formed. This structure greatly enhances the bending and shear resistance of the cage corners, effectively prevents the cage from torsional deformation when subjected to lateral forces or uneven loads, ensures the geometric stability of the cage, and makes the overall structure more robust.

[0019] As an optional embodiment, the second support tube 10 and the third support tube 11 abut against each other in sequence to form support for the support side plate 2 and the support back plate 3, and the pin 12 passing through the second pin hole simultaneously limits the support side plate 2 and the support side plate 3.

[0020] In an embodiment of this utility model, three first limiting grooves 13 are provided at the edge of the upper surface of the base 1, and the bottoms of the supporting side plate 2 and the supporting back plate 3 are respectively embedded in the first limiting grooves 13.

[0021] As an optional embodiment, a second limiting groove 14 is provided at the center of the first limiting groove 13. Limiting blocks 15 are fixedly connected to the bottom of the supporting side plate 2 and the supporting back plate 3 respectively. Each limiting block 15 is disposed in the second limiting groove 14. The limiting block 15 cooperates with the pin 12. The limiting block 15 provides vertical limiting and cooperates with the limiting frustum 6 to fix the supporting side plate 2 and the supporting back plate 3 on the base 1. The pin 12 provides horizontal limiting for the supporting side plate 2 and the supporting back plate 3 to ensure the stability of the overall structure.

[0022] In this embodiment of the invention, both the supporting side plate 2 and the supporting back plate 3 are truss plates, preferably a cross-shaped truss. Compared to a solid plate of the same weight, a cross-shaped truss plate has higher strength and rigidity, and can bear the maximum load with the least amount of material. This allows the cage to significantly reduce its own weight while ensuring its load-bearing capacity, which not only reduces the energy consumption of the lifting equipment, but also makes individual plates lighter, facilitating workers' handling and assembly.

[0023] In an embodiment of this utility model, a sliding groove 17 is fixedly connected to the side of the first support tube 9 facing away from the support side plate 2. The two sliding grooves 17 are L-shaped sliding grooves 17 arranged opposite each other, and the door panel 16 is disposed in the sliding groove 17.
