Description

Technical Field

[0001] This application relates to the technical field of lifting devices, and in particular to a construction lifting device for building construction. Background Technology

[0002] Construction scaffolding used in building construction projects is an essential tool for lifting, transporting, and installing building materials and equipment. These scaffolds are designed to ensure the safe transport of materials during construction and to improve work efficiency.

[0003] In related technologies, lifting frames mainly consist of steel wire ropes used to bear the tension of heavy objects and are suitable for lifting materials vertically or horizontally. Hooks are used to connect the object being lifted to a crane or other lifting equipment, and clamps are mounted on the hooks to hold specific types of heavy loads.

[0004] Regarding the aforementioned lifting system, when hoisting cylindrical precast components, lifting lugs are typically pre-installed on the outer circumferential wall of the component. Then, clamps are suspended from the lugs, and finally, the crane lifts the component using a traction wire rope. During hoisting, the top of the wire rope converges towards the central axis of the cylindrical precast component, applying a component force towards its central axis. For thinner cylindrical precast components, this prolonged pressure can cause deformation, directly affecting subsequent assembly and potentially rendering the component unusable. Utility Model Content

[0005] This application provides a construction hoist for building construction, which can ensure that the cylindrical prefabricated components are not easily deformed during hoisting, thus ensuring the structural stability of the cylindrical prefabricated components during hoisting and reducing the scrap rate.

[0006] This application provides a construction scaffolding system for building construction, which adopts the following technical solution:

[0007] A construction hoist for building construction includes multiple main steel wire ropes, each with a hook at its top for connection to a crane boom. It also includes a hoisting seat for placement inside a precast cylindrical component and multiple lifting lugs for fixing to the outer circumference of the precast cylindrical component. The hoisting seat has a support ring for contacting the inner wall of the precast cylindrical component, and the support ring is coaxial with the component. A balance cross beam is suspended and fixed at the bottom of the main steel wire ropes. Each balance cross beam has a hoisting rope corresponding to one of the lifting lugs, with the upper end of each rope suspended and fixed to the balance cross beam and the lower end suspended and fixed to its corresponding lifting lug. A traction rope is suspended and fixed between the hoisting seat and the balance cross beam, and the traction rope is located on the central axis of the hoisting seat.

[0008] Preferably, a threaded post is fixedly provided on the lifting lug, and the threaded post is sequentially passed through the cylindrical prefabricated component and the support ring. The end of the threaded post is threadedly connected to a nut located in the lifting seat, and the nut tightens and fixes the lifting lug to the cylindrical prefabricated component and the support ring.

[0009] Preferably, the top of the support ring is provided with a clamping member, and the clamping member has a relief groove formed on it for the top edge of the cylindrical prefabricated component to be inserted into the clamping member. A screw is threadedly connected to the clamping member, and the end of the screw is screwed into the relief groove.

[0010] Preferably, an auxiliary steel wire rope is suspended and fixed between the balance cross beam and the hook, and the auxiliary steel wire rope is located on the central axis of the balance cross beam.

[0011] Preferably, each of the main steel wire ropes is connected to the same spacer disc, and the spacer disc has multiple through holes corresponding to the main steel wire ropes, with each main steel wire rope passing through its respective through hole.

[0012] Preferably, the spacer disc is movably threaded on the auxiliary steel wire rope, and a wire clamp is detachably installed on the auxiliary steel wire rope, with the spacer disc positioned above the wire clamp.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] The cross beam can effectively reduce the radial force exerted on the cylindrical precast component by the main wire rope during hoisting, thereby making the cylindrical precast component less prone to extrusion deformation, ensuring the structural stability of the cylindrical precast component during hoisting, and keeping the cylindrical precast component in balance;

[0015] The hoisting seat located inside the cylindrical precast component can support the inner wall of the cylindrical precast component, thereby further improving the deformation resistance of the cylindrical precast component, making the cylindrical precast component more stable during hoisting, and greatly reducing the scrap rate;

[0016] The spacer can reduce the offset of the main wire rope during hoisting, improve the stability of the main wire rope 1 during hoisting, and make the cylindrical precast component more stable. Attached Figure Description

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a construction hoist for building construction.

[0023] Reference Figure 1 , Figure 2 The construction scaffold for building construction includes four main steel wire ropes 1, with hooks 2 suspended and fixed at the top of the four main steel wire ropes 1 for connection and fixation to the boom of a crane. It also includes a lifting seat 3 for placement inside a cylindrical precast component. A support ring 30 is fixedly installed on the lifting seat 3 to fit against the inner wall of the cylindrical precast component. The outer diameter of the support ring 30 matches the inner diameter of the cylindrical precast component, and the support ring 30 placed inside the cylindrical precast component is coaxial with the cylindrical precast component.

[0024] like Figure 2 , Figure 3 As shown, the bottom of the main wire rope 1 is suspended and fixed to the same balance cross beam 5 by a buckle. Four circumferentially evenly spaced lifting lugs 4 are provided on the outer circumference of the cylindrical precast component. Threaded posts 40 are fixedly installed on the lifting lugs 4. The threaded posts 40 are sequentially inserted into the cylindrical precast component and the support ring 30 along the radial direction of the cylindrical precast component. The end of the threaded post 40 is threadedly connected to a nut 41 located in the lifting seat 3. The nut 41 tightens and fixes the lifting lugs 4 to the cylindrical precast component and the support ring 30.

[0025] like Figure 2 , Figure 3 As shown, four lifting ropes 50 are detachably installed at the bottom of the balance cross beam 5, each corresponding to a lifting lug 4. The upper ends of the lifting ropes 50 are suspended and fixed to the balance cross beam 5 via clips, and the lower ends of the lifting ropes 50 are suspended and fixed to their respective lifting lugs 4 via clips. A traction rope 6 is suspended and fixed between the lifting seat 3 and the balance cross beam 5 via clips, and the traction rope 6 is located on the central axis of the lifting seat 3. The balance cross beam 5 can effectively reduce the radial force exerted on the cylindrical precast component by the main wire rope 1 during lifting, thereby making the cylindrical precast component less prone to compression deformation, ensuring the structural stability of the cylindrical precast component during lifting, and keeping the cylindrical precast component balanced. In addition, the lifting seat 3 located inside the cylindrical precast component can support the inner wall of the cylindrical precast component, thereby further improving the deformation resistance of the cylindrical precast component, making the cylindrical precast component more stable during lifting, and greatly reducing the scrap rate.

[0026] like Figure 2 , Figure 3 As shown, four clamping members 7 are fixedly installed on the top of the support ring 30, and the clamping members 7 are evenly spaced around the support ring 30 in a circumferential manner. Each clamping member 7 has a relief groove 70 formed therein for the top edge of the cylindrical prefabricated component to be inserted from bottom to top. A screw 71 located outside the cylindrical prefabricated component is threadedly connected to the outer wall of the clamping member 7. The end of the screw 71 is screwed radially into the relief groove 70 along the cylindrical prefabricated component and abuts against the outer wall of the cylindrical prefabricated component. The clamping members 7 and the screw 71 can further fix the cylindrical prefabricated component to the lifting base 3, thereby further enhancing the connection strength between the cylindrical prefabricated component and the lifting base 3.

[0027] The specific hoisting steps are as follows: First, the hoisting base 3 is placed inside the cylindrical precast component from top to bottom using a crane. Then, the lifting lugs 4 are sequentially fixed onto the cylindrical precast component and the support ring 30. At this time, the top edge of the cylindrical precast component is inserted into the relief groove 70 of the clamping member 7 from bottom to top. By tightening the screw 71, the end of the screw 71 is pressed against the outer wall of the cylindrical precast component, which further enhances the connection strength between the cylindrical precast component and the hoisting base 3, ensuring the reliability of the connection between the two. After the cylindrical precast component is hoisted to the designated position, the lifting lugs 4 on the cylindrical precast component can be disassembled by unscrewing the nut 41 from the threaded post 40, which facilitates the disassembly and assembly of the lifting lugs 4 and allows for their reuse. Finally, the hoisting base 3 is lifted out of the cylindrical precast component to complete the hoisting work.

[0028] like Figure 2 , Figure 3As shown, a secondary steel wire rope 8 is suspended and fixed between the balance cross beam 5 and the hook 2 via a clip. Four main steel wire ropes 1 are arranged circumferentially around the secondary steel wire rope 8, and the secondary steel wire rope 8 is located on the central axis of the balance cross beam 5. A spacer disc 9 is provided between each main steel wire rope 1. Multiple through holes 90, corresponding one-to-one with the main steel wire ropes 1, are passed through the spacer disc 9, and each main steel wire rope 1 is threaded into its respective through hole 90. The spacer disc 9 can reduce the offset of the main steel wire ropes 1 during hoisting, improve the stability of the main steel wire ropes 1 during hoisting, and make the cylindrical precast component more stable.

[0029] like Figure 2 , Figure 3 As shown, the spacer disc 9 is movably mounted on the outside of the auxiliary wire rope 8. A wire clamp 80 is detachably mounted on the auxiliary wire rope 8. The spacer disc 9 is positioned above the wire clamp 80. The wire clamp 80 includes two symmetrically arranged pressure plates and fastening bolts sequentially mounted on the pressure plates. The ends of the fastening bolts are threaded with fastening nuts. The bottom of the spacer disc 9 is fixed to one of the pressure plates. By unscrewing the fastening nuts from the fastening bolts, the height of the spacer disc 9 can be adjusted up and down along the length of the auxiliary wire rope 8. This allows for adjustment of the spacer disc 9's installation position on the main wire rope 1.

[0030] The implementation principle is as follows: The balancing cross beam 5 effectively reduces the radial force exerted on the cylindrical precast component by the main wire rope 1 during hoisting, thus preventing the cylindrical precast component from undergoing extrusion deformation and ensuring its structural stability during hoisting, keeping it balanced. Furthermore, the hoisting seat 3 located inside the cylindrical precast component supports its inner wall, further enhancing its resistance to deformation and making it more stable during hoisting, significantly reducing the scrap rate. The clamping member 7 and the screw 71 further secure the cylindrical precast component to the hoisting seat 3, thereby further strengthening the connection between them. The spacer 9 reduces the offset of the main wire rope 1 during hoisting, improving its stability and making the cylindrical precast component more stable.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
