Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a prefabricated hoisting cage. Background Technology

[0002] Currently, in many construction sites, the traditional method of tying steel wire ropes for material hoisting is commonly used. This method typically involves laying steel wire ropes on the ground, moving the materials to be hoisted (such as steel pipes, timber, bricks, polycore molds, composite slabs, cup-lock scaffolding pipes, etc.) above the ropes, then securing the ropes and attaching them to hooks for lifting. Although this hoisting method is relatively simple, it has several safety hazards and technical limitations, especially when hoisting irregular, easily slippery, easily damaged, or unevenly weighted materials, which can easily lead to instability, loss of control, or material breakage.

[0003] First, the binding operation of wire ropes is complex and prone to imbalance, especially when lifting irregularly shaped materials. An unstable center of gravity can lead to an unstable lifting process, resulting in low safety. Second, because ropes are prone to shifting or misalignment, this can cause problems such as tilting or rotating of the lifted materials, increasing the risk of accidents. This is especially true for fragile or easily damaged materials (such as polycore molds), which may suffer surface damage during lifting.

[0004] Therefore, to solve the above problems, a prefabricated hoisting cage is needed that can quickly and reliably transport hoisting materials to the designated location. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a prefabricated hoisting cage that can quickly and reliably transport hoisting materials to a designated location.

[0006] The prefabricated cage of this utility model includes a cage enclosure, a cage base and a connecting mechanism; the cage enclosure is detachably mounted on the cage base through the connecting mechanism, and the top of the cage enclosure has upper lifting lugs, which include a plurality of lugs evenly distributed around the central axis of the cage enclosure.

[0007] The cage base has a blocking part that limits the bottom of the cage enclosure.

[0008] Furthermore, the cage enclosure is provided with a positioning part sleeved on the blocking part. The positioning part and the blocking part are assembled in a one-to-one correspondence relationship to form a set of limiting components. The limiting components include several sets evenly distributed around the central axis of the cage enclosure.

[0009] Furthermore, the cage base has legs evenly distributed around the circumference of the cage base, and also includes a counterweight assembly with the same number of legs. The counterweight assembly includes several counterweight blocks corresponding to one of the legs, and each counterweight block is detachably connected to the corresponding leg.

[0010] Furthermore, the outrigger has a receiving cavity, in which several counterweights are disposed. The receiving cavity has an opening that can be controlled to open and close, so that the counterweights can be controlled to be placed in or removed from the receiving cavity.

[0011] Furthermore, the bottom of the cage enclosure has lower lifting lugs, and the connecting mechanism includes a sleeve fixed to the bottom of the cage base and a main support rod that passes through the sleeve and is limited by the sleeve; the lower lifting lugs include two that are arranged opposite to each other and located at both ends of the sleeve; the main support rod is driven to pass through the two lower lifting lugs and the sleeve to limit the cage enclosure to the cage base, or to be removed from the two lower lifting lugs and the sleeve to release the limitation.

[0012] Furthermore, the first end of the main support rod has a blocking flange, the outer contour dimension of which exceeds the outer contour dimension of the lower lifting lug and the outer contour dimension of the sleeve, so that after the main support rod passes through the lower lifting lug which is close to the blocking flange, it is limited to the inner side of the blocking flange.

[0013] The second end of the main support rod has a pin hole. After the main support rod passes through two lower lifting lugs and a sleeve, the pin hole is located on the outside of the lower lifting lugs that are close to it. The connecting mechanism also includes a locking assembly. The locking assembly includes a fixed seat set at the bottom of the cage base and a toggle pin set at the fixed seat. The toggle pin is driven to insert into the pin hole, which limits the lower lifting lug that is close to the pin hole to the inside of the toggle pin. The toggle pin is also driven to disengage from the pin hole, so that the main support rod is driven to be removed from the two lower lifting lugs and the sleeve, thereby releasing the limitation of the cage base and the cage enclosure.

[0014] Furthermore, the pin hole has an anti-rotation surface, and the actuating pin has a blocking surface adapted to the anti-rotation surface.

[0015] Furthermore, the locking assembly also includes an elastic element disposed on the actuating pin, the elastic element providing a preload force for the actuating pin to extend into the pin hole; when the actuating pin is removed from the pin hole, it overcomes the preload force.

[0016] Furthermore, the connecting mechanism includes two sets symmetrically arranged around the center of the cage base, and the corresponding lower lifting lugs also consist of two sets.

[0017] The beneficial effects of this utility model are as follows: The prefabricated hoisting cage disclosed in this utility model significantly improves the efficiency and safety of hoisting operations through the detachable connection between the hoisting cage enclosure and the hoisting cage base. It makes the loading and unloading of parts more convenient, and the hoisting cage enclosure can form protection for special parts, enhance the protection of irregular shapes and fragile materials, reduce the risk of material damage, and ensure construction safety. For example, it is highly practical for accommodating and hoisting loose materials, irregularly shaped components, or parts with unstable centers of gravity. Attached Figure Description

[0024] Figure 1 As shown in the figure, the prefabricated hoisting cage in this embodiment includes a hoisting cage enclosure 1, a hoisting cage base 2, and a connecting mechanism. The hoisting cage enclosure 1 is detachably mounted on the hoisting cage base 2 via the connecting mechanism. The connecting mechanism can be bolt assembly or pin locking, etc., to achieve the purpose of detachable connection, which will not be elaborated here. The detachable connection between the hoisting cage enclosure 1 and the hoisting cage base 2 significantly improves the efficiency and safety of hoisting operations, makes the loading and unloading of parts more convenient, and the hoisting cage enclosure 1 can provide protection for special parts, enhance the protection of irregular shapes and fragile materials, reduce the risk of material damage, and ensure construction safety. For example, it can accommodate and hoist loose materials, irregularly shaped components, or parts with unstable centers of gravity, making it highly practical.

[0025] Specifically, the vertical projection of the cage enclosure 1 is rectangular, the cage enclosure 1 is closed circumferentially and open at the top and bottom; it cooperates with the cage base 2 to form a housing compartment for protecting the parts to be transported. Of course, a cylindrical cage enclosure 1 or a cage enclosure 1 of other structures can be set according to the actual situation, which will not be described in detail here.

[0026] The top of the cage enclosure 1 has upper lifting lugs 3, which include several evenly distributed around the central axis of the cage enclosure 1. Preferably, in this scheme, there are four upper lifting lugs 3 evenly distributed around the central axis of the cage enclosure 1, with each pair of upper lifting lugs 3 arranged opposite each other along the width direction of the cage enclosure 1 forming a group, and two groups arranged along the length direction of the cage enclosure 1. By using several upper lifting lugs 3 to lift the cage enclosure 1 and the cage base 2, the overall structure is subjected to more uniform force, and the structure is more stable and reliable. This avoids the risks of imbalance and material slippage caused by improper rope operation in traditional hoisting methods, ensuring the efficiency and safety of the hoisting process. It can guarantee the reliable loading and transportation of building materials. Furthermore, the detachable structure can be reused, and the accessories are easy to replace, resulting in lower costs.

[0027] In this embodiment, the bottom of the cage enclosure 1 has lower lifting lugs 4. The connecting mechanism includes a sleeve 5 fixed to the bottom of the cage base 2 and a main support rod 6 passing through the sleeve 5 and limited by the sleeve 5. The structure of the sleeve 5 and the main support rod 6 can also increase the load-bearing capacity of the cage base 2 and improve safety. The lower lifting lugs 4 include two that are arranged opposite each other and located at both ends of the sleeve 5. The main support rod 6 is driven to pass through the two lower lifting lugs 4 and the sleeve 5 to limit the cage enclosure 1 to the cage base 2, or to be removed from the two lower lifting lugs 4 and the sleeve 5 to release the limitation. Through the assembly structure of the main support rod 6 and the lower lifting lugs 4, the cage enclosure 1 and the cage base 2 can be assembled together or disassembled into two sections more quickly, reducing the loading and unloading time in traditional hoisting methods and improving material feeding efficiency.

[0028] The first end of the main support rod 6 has a blocking flange 7. The outer contour dimension of the blocking flange 7 exceeds the outer contour dimension of the lower lifting lug 4 and the outer contour dimension of the sleeve 5, so that after the main support rod 6 passes through the lower lifting lug 4 which is close to the blocking flange 7, it is limited to the inner side of the blocking flange 7. Due to the through-through structure of the main support rod 6, the blocking flange 7 set on one side is simpler in structure and can prevent the lower lifting lug 4 on that side from detaching, making the implementation more convenient and faster, and the safety better.

[0029] The second end of the main support rod 6 has a pin hole. After the main support rod 6 passes through two lower lifting lugs 4 and a sleeve 5, the pin hole is located on the outside of the lower lifting lug 4 that is close to it. The connecting mechanism also includes a locking assembly, which includes a fixed seat 10 disposed at the bottom of the cage base 2 and a deflecting pin 8 disposed at the fixed seat 10. The deflecting pin 8 is driven to insert into the pin hole, which limits the lower lifting lug 4 that is close to the pin hole to the inside of the deflecting pin 8. The deflecting pin 8 is also driven to disengage from the pin hole, so that... The main support rod 6 is driven to be removed from the two lower lifting lugs 4 and the sleeve 5 to release the limiting position of the cage base 2 and the cage enclosure 1; the pin hole has an anti-rotation surface, and the actuating pin 8 has a blocking surface adapted to the anti-rotation surface; to improve structural reliability, the locking assembly also includes an elastic element 9 disposed on the actuating pin 8, the elastic element 9 providing a preload force for the actuating pin 8 to extend into the pin hole; to improve structural safety, the elastic element 9 is a spring, which overcomes the preload force when the actuating pin 8 is removed from the pin hole.

[0030] The locking component's plug-in / plug-out structure allows for quick assembly and disassembly of the main support rod 6 in a single operation, making it more convenient to operate. Furthermore, the presence of the elastic element 9 enhances the safety of the entire device.

[0031] Specifically, there are four lower lifting lugs 4, which are the same number as the upper lifting lugs 3. Each lower lifting lug 4 is positioned opposite to the upper lifting lug 3 in the height direction, forming two sets of lower lifting lugs 4 positioned opposite each other along the width direction of the cage enclosure 1. Each set of lower lifting lugs 4 is matched with a main support rod 6, which limits the cage enclosure 1 and the cage base 2 to form a whole, making its center of gravity closer to the middle of the whole, which is suitable for the transportation of various components.

[0032] The upper lifting lug 3 and the lower lifting lug 4 are flexible steel cables welded at corresponding positions to facilitate the connection of the upper lifting lug 3 with the lifting equipment and the lower lifting lug 4 with the main support rod 6.

[0033] The connecting mechanism includes a sleeve 5 fixed to the bottom of the cage base 2 and a main support rod 6 that passes through the sleeve 5 and is limited by the sleeve 5. The main support rod 6 is rod-shaped and has an irregular shape structure with a rounded bottom and a rectangular top. The sleeve 5 has an inner cavity for the main support rod 6 to pass through. The inner cavity of the sleeve 5 has the same structure as the main support rod 6, so that the sleeve 5 can guide the main support rod 6 while also forming an assembly with it, resulting in higher overall strength. In addition, the rounded bottom of the main support rod 6 is adapted to the structure of the lower lifting lug 4, which is conducive to assembly and improves construction efficiency.

[0034] The blocking flange 7 is disc-shaped and is disposed at one end of the main support rod 6. After the sleeve 5 passes through the main support rod 6, it serves to limit the lower lifting lug 4 that is close to it. The structure is simple and the limiting is reliable.

[0035] The main support rod 6 has a pin hole at one end, where the pin hole is a rectangular hole, and the actuating pin 8 that cooperates with the pin hole is a rectangular cube structure that is adapted to it. The two brake each other and have the function of preventing rotation, thus improving structural safety. In addition, the end of the actuating pin 8 near the pin hole has a slope to facilitate the formation of a guide and improve assembly efficiency.

[0036] The locking assembly includes a fixed seat 10 that runs parallel to and abuts against the sleeve 5 along its length, enhancing the support capacity for the cage base 2. The fixed seat 10 is bent near the pin hole to form an assembly part. When the main support rod 6 cooperates with the locking assembly, the bent position is used to accommodate the lower lifting lug 4. The actuating pin 8 passes through the assembly part and cooperates with the pin hole. An assembly cavity is opened in the assembly part. The spring sleeves the actuating pin 8 in the assembly cavity. The actuating pin 8 has a resistance plate 11 located in front of the spring in the assembly cavity and a pull plate 12 located behind the spring outside the assembly cavity. The preload of the spring presses the resistance plate 11 against the inner wall of the assembly cavity and also presses the pull plate 12 against the outer wall of the assembly cavity.

[0037] When the main support rod 6 is engaged with the locking assembly, the actuating pin 8 remains in the pin hole. By applying a force to the pull plate 12 to overcome the preload, the actuating pin 8 can be moved to disengage from the pin hole. The locking assembly of this solution has a simple structure, is easy to operate, has a close fit with the main support rod 6, and has higher structural strength.

[0038] Preferably, the connecting mechanism includes two sets symmetrically arranged around the center of the cage base 2, and the corresponding lower lifting lugs 4 are also two sets, which improves the overall structural stability of the cage and correspondingly increases the load-bearing capacity.

[0039] In this embodiment, the cage base 2 has a blocking part 13 that limits the bottom of the cage enclosure 1, and the cage enclosure 1 is provided with a positioning part 14 sleeved on the blocking part 13.

[0040] The positioning part 14 and the blocking part 13, which are assembled in a one-to-one correspondence, form a set of limiting components. The limiting components include several sets evenly distributed around the central axis of the cage enclosure 1.

[0041] Specifically, the limiting components include four sets corresponding to each side of the cage enclosure 1, with each set positioned at the center of the bottom edge of the corresponding side. The cooperative structure of the blocking part 13 and the limiting part further improves the positioning accuracy between the cage base 2 and the cage enclosure 1, and also helps prevent structural separation or tilting after the assembly of the split structure, resulting in better structural stability and safety, avoiding potential safety hazards in traditional hoisting methods. The blocking parts 13 in the two opposing sets of limiting components are interconnected, forming a cross-shaped reinforced structure at the bottom of the cage base 2. In this design, the bottom end of the cage base 2 is provided with reinforcing ribs to further enhance its strength.

[0042] In this embodiment, the cage base 2 has legs 15 evenly distributed around its circumference for supporting the cage base 2. It also includes a counterweight assembly with the same number of legs 15. The counterweight assembly includes several counterweight blocks 16 corresponding to one of the legs 15, each counterweight block 16 being detachably connected to its corresponding leg 15. Each leg 15 has a receiving cavity, within which several counterweight blocks 16 are disposed. The receiving cavity has an opening that can be controlled to open and close, allowing the counterweight blocks 16 to be controlled to be placed within or removed from the receiving cavity. By adjusting the number of counterweight blocks 16 in each leg 15, the center of gravity of the entire cage is shifted, making it suitable for structures where the center of gravity is not at the center of the lifting component. This further ensures the overall lifting stability, prevents the cage from tilting, and enhances safety.

[0043] Specifically, in this design, the outrigger 15 has an open bottom structure. The counterweight assembly includes three counterweight blocks 16 and a set of U-bolts 17 with locking nuts. One counterweight block 16 is detachably fixed to the open end of the outrigger 15 by passing through itself and the U-bolts 17 of the outrigger 15, which is used to control the opening and closing of the open end and ensures structural stability. The other two counterweight blocks 16 are stacked on top of this counterweight block 16 and are adjustable inside or outside the outrigger 15, thus completing the adjustable counterweight function of the outrigger 15. The outrigger 15 with the counterweight assembly includes four legs respectively distributed at the four corners of the cage base 2 to achieve reliable adjustment of the overall center of gravity. This is beneficial for hoisting irregularly shaped structural components or components whose center of gravity is not in the center, and the safety is better. When hoisting structural components with a stable center of gravity, no counterweight assembly is set inside the outrigger 15, which reduces the weight of the overall structure and improves construction efficiency.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
