Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable steel cage hole hoisting device. Background Art

[0002] Steel cages are common structural components in construction projects. They consist of multiple longitudinal steel bars and stirrups connected by tying or welding at a certain spacing and arrangement to form a skeleton. They are commonly used in concrete structures such as pile foundations, beams, and columns. Steel cages are mainly used to enhance the compressive and tensile properties of concrete, ensuring that the components have sufficient strength and rigidity to withstand the load of the building.

[0003] During the installation of rebar cages, traditional hoisting methods have many limitations and cannot fully meet the needs of modern construction. First, poor dimensional adaptability is a significant problem with traditional rebar cage hoisting methods. Traditional hoisting equipment is mostly designed with fixed dimensions, making it difficult to adapt to rebar cages of different specifications and shapes. When faced with large or unusually shaped rebar cages, the equipment often cannot be flexibly adjusted, resulting in unstable balance during the hoisting process, increasing the difficulty of construction. Second, insufficient positioning accuracy also affects construction quality. Traditional methods cannot achieve high-precision alignment when hoisting the rebar cage to the orifice, and deviations are prone to occur between the rebar cage and the orifice, affecting the overall construction accuracy and the smooth progress of subsequent processes. In addition, traditional hoisting methods also have significant limitations in operational flexibility. Especially in construction environments with limited space, the equipment is difficult to flexibly adjust according to actual conditions, and the hoisting angle and position cannot be quickly changed. This operational rigidity makes the construction process cumbersome, difficult, and increases construction risks. Finally, safety and efficiency issues are important shortcomings of traditional methods. Due to inadequate protective measures, safety hazards are prone to occur during construction.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 3 As shown, an adjustable steel cage hole lifting device includes: a casing cross arm 1, on which a plurality of evenly arranged adjustment holes 2 are opened; a connecting portion 3 is detachably connected to the casing cross arm 1, and a reinforcing steel plate 5 is welded to the side of the connecting portion 3; at least one hook 4 is arranged on the side of the connecting portion 3, and the hooks 4 are equidistantly distributed along the side of the connecting portion 3, and the hooks 4 are C-shaped.

[0025] The design of this device uses the casing crossarm 1 to bear the weight of the steel cage, and the adjustment hole 2 allows the casing crossarm 1 to be adjusted according to different steel cage diameters. The connection part 3 is connected to the casing crossarm 1 in a detachable manner, which is convenient for disassembly and transportation of the equipment. The reinforcing steel plate 5 welded on the side increases the structural strength of the connection part 3 to ensure that it will not deform or bend during the lifting process. The hook 4 is a C-shaped design, equidistantly distributed along the side of the connection part 3 to ensure uniform lifting force and reduce lifting offset or steel cage swing. The adjustment hole 2 on the casing crossarm 1 can be adjusted according to demand to accommodate steel cages of different specifications. The addition of the reinforcing steel plate 5 significantly enhances the strength of the connection part 3 to prevent fatigue damage caused by long-term load-bearing. The C-shaped hook 4 design makes the force distribution during the lifting process more uniform, reduces the risk during lifting, and ensures operational safety.

[0026] The casing crossarm 1 and the reinforcing steel plate 5 can be made of different high-strength alloy materials to further improve durability. In addition to the C-shaped hook, hooks of other shapes (such as S-shaped or L-shaped) can also be used to adapt to different types of steel cage designs. The connection method between the connecting part 3 and the casing crossarm 1 is not limited to bolt connection, and quick snap connection can also be used to further improve loading and unloading efficiency.

[0027] In a possible implementation manner, the connecting portion 3 is detachably connected to the casing cross arm 1 via bolts, and the diameter of the bolts is 5 mm.

[0028] Bolting the connection 3 to the casing crossarm 1 facilitates quick disassembly and installation. The 5mm diameter bolts provide sufficient connection strength to prevent the device from loosening during installation. The bolted connection simplifies maintenance and repair while ensuring a secure connection. The 5mm diameter bolts provide sufficient strength while maintaining a low structural weight, making the overall device easier to operate.

[0029] The size and material of the bolts can be adjusted according to actual needs. For example, bolts of different diameters can be used or quick-release buckles can be used to further improve the installation efficiency of the device.

[0030] In a possible embodiment, the surface of the casing cross arm 1 is provided with an anti-slip coating.

[0031] The anti-slip coating on the surface of the casing crossarm 1 effectively increases friction with the contact portion of the steel cage, preventing the steel cage from sliding during hoisting and improving the stability of the hoisting operation. The anti-slip coating can effectively reduce the risk of the steel cage sliding during hoisting, thereby improving the safety of the device. At the same time, the anti-slip coating can also provide a certain degree of protection for the casing crossarm 1, reducing wear and extending its service life.

[0032] The anti-slip coating can be made of different materials or processes, such as rubber coating or sandblasting, to further improve the anti-slip effect or increase the corrosion resistance of the device.

[0033] In a possible implementation manner, a rubber buffer layer is provided on the inner side of the hook 4 .

[0034] The rubber buffer layer can provide additional cushioning protection during the lifting process, reduce friction and collision between the hook and the steel cage, and avoid damage to the surface of the steel cage. This design can effectively prevent surface damage to the steel cage during the lifting process, while also improving the stability of the lifting and reducing the risks caused by vibration and collision.

[0035] Cushioning materials can be made of other materials according to different usage environments, such as soft plastics or foam materials, to enhance durability or adapt to different working conditions.

[0036] In a possible implementation manner, the casing cross arm 1 is provided with a plurality of hook interfaces of different sizes, and the hook interfaces are connected to the hooks 4 .

[0037] Hook interfaces of varying sizes allow the device to be replaced based on specific lifting requirements, adapting to different sizes of rebar cages. Hook 4 can be quickly replaced through the interface, increasing flexibility. This design significantly improves the versatility and adaptability of the device, making it suitable for lifting rebar cages of varying sizes, reducing on-site tool replacement time and improving work efficiency.

[0038] The hook interface can be in the form of a snap-on type or a slide rail type, further improving the convenience of hook replacement.

[0039] In a possible implementation manner, stress sensors are further provided at both ends of the casing cross arm 1 .

[0040] The stress sensor can monitor the stress of the casing cross arm 1 in real time during the hoisting process, provide data feedback, and ensure the safety of the steel cage during the hoisting process. The application of the stress sensor improves the safety of the hoisting process, can detect overload conditions in time, avoid accidents, and enhance the intelligence and monitoring functions of the device.

[0041] The stress sensor can be replaced with other types of sensors, such as displacement sensors or acceleration sensors, to further increase the monitoring range and accuracy of the device.

[0042] In a possible implementation manner, a protective cover is provided on the outside of the casing cross arm 1 and the connecting portion 3 .

[0043] The protective cover is used to protect the casing cross arm 1 and the connecting part 3 from damage by the external environment, such as rain, dust, etc., to extend the service life of the device. The protective cover effectively improves the service life of the device in harsh environments, reduces the erosion of the external environment on the key components of the device, and also reduces the maintenance frequency.

[0044] The protective cover can be made of transparent material to facilitate operators to observe the working status of the device, or adopt UV protection coating to increase its service life in outdoor environments.

[0045] In a possible implementation, a buffer spring is provided inside the hook 4 .

[0046] The buffer spring can absorb and alleviate the impact force of the steel cage during the lifting process, further reduce the vibration generated during the lifting process, and ensure the smoothness of the operation. The design of the buffer spring can reduce the impact force during lifting, effectively protect the steel cage and device, and improve the stability and safety of the lifting process.

[0047] The buffer device can adopt other forms of shock-absorbing structures, such as hydraulic buffers or air cushions, to adapt to different working requirements.

[0048] In one possible embodiment, a buckle is provided on the top of the hook 4. The buckle design can provide additional fixation when the hook 4 is connected to the steel cage, prevent the steel cage from falling off, and improve the safety during the lifting process. The buckle design further enhances the fixing function of the hook, ensuring that the steel cage will not loosen or fall off during the lifting process, greatly improving the safety and reliability of the operation.

[0049] The buckle can be designed as a spring locking type or a magnetic adsorption type to improve the convenience and reliability of the buckle operation.

[0050] Working process: First, the operator selects the appropriate adjustment hole 2 and installs the corresponding connection part 3 so that it can be adjusted according to the diameter of the steel cage. The connection part 3 is detachably connected to the casing cross arm 1 through bolts. The diameter of the bolt is 5mm, which ensures the firm connection between the connection part 3 and the casing cross arm 1. C-shaped hooks 4 are provided on the side of the connection part 3. These hooks 4 are evenly distributed along the side of the connection part 3 to ensure uniform force during the lifting process. Hooks of different sizes can also be selected on the hook 4 through the hook interface to adapt to different steel cage sizes. The operator fixes the orifice of the steel cage on the hook 4. In order to avoid damage to the steel cage during the lifting process, the hook 4 A rubber buffer layer is provided on the inner side, which can reduce the friction between the steel cage and the hook to prevent surface damage. In some cases, a buffer spring is also provided inside the hook 4, which can absorb and alleviate the impact force during hoisting, further improving the stability and safety of hoisting. A buckle is provided on the top of the hook 4 to ensure that the steel cage is firmly fixed on the hook to prevent it from falling off during the lifting process. The lifting equipment is connected to the casing cross arm 1, and the steel cage is lifted by the equipment. During this process, the weight of the steel cage is borne by the casing cross arm 1 and the connecting part 3. The hook 4 ensures that the steel cage does not deviate or slide. The surface of the casing cross arm 1 is provided with an anti-slip coating. It can increase the friction of the contact part with the steel cage, further avoid sliding, and ensure safety and stability during the lifting process. If the equipment is equipped with stress sensors (located at both ends of the casing cross arm 1), the stress sensors will monitor the stress of the casing cross arm 1 in real time during the lifting process to ensure that the device works within the load range. When abnormal stress is detected, it can be adjusted in time to prevent the device from overloading or other safety problems. In order to prevent the external environment from affecting the device during the lifting process, a protective cover is provided on the outside of the casing cross arm 1 and the connecting part 3. The protective cover can effectively protect the key structure from external environment such as dust, rain, etc., prolonging the service life of the equipment and ensuring the lifting process. During the process, the operator can make adjustments based on the real-time load conditions. If the specifications of the steel cage change, the size configuration of the lifting device can be changed by adjusting the adjustment hole 2 on the casing cross arm 1 to adapt it to different steel cages. During the entire lifting process, the optimized adjustment design and structurally reinforced connection part 3 and reinforced steel plate are used to ensure that the equipment has high stability and safety. After the lifting is completed, the operator places the steel cage in the designated position and unhooks the hook 4 by releasing the buckle to remove the steel cage from the lifting device. During disassembly, the bolt connection design allows the connection part 3 to be quickly separated from the casing cross arm 1, which is convenient for disassembly and storage of the device.
