Technical Field
[0001] This application relates to the field of prefabricated building construction equipment technology, and in particular to a hoisting construction device for assembling prefabricated components. Background Technology
[0002] Prefabricated buildings are a type of structure that assembles various reinforced concrete precast components according to design requirements. Construction of prefabricated buildings often involves the hoisting of various precast components, which mainly include wall panels, composite slabs, balconies, stairs, precast beams, and precast columns. All precast components have pre-embedded lifting rings during the prefabrication process.
[0003] During the hoisting process, factors such as the acceleration / deceleration of the lifting equipment, wind force, or improper operation by personnel can exacerbate the swaying of precast components. Current hoisting processes involve observing whether the corresponding plane of the precast component is roughly horizontal or vertical, adjusting the state of the hoisting components on the hoisting device, hoisting the component to the designated position, and then having workers receive the component and accurately adjust it to the appropriate state before lowering it to the ground. Thus, workers are already waiting at the designated position before the component lands. If the component is affected by the above factors and sways at this time, it will pose a safety hazard to the workers on the ground. Therefore, this application proposes a new technical solution. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0020] This application discloses a hoisting construction device for assembling prefabricated components.
[0021] Reference Figure 1 The hoisting construction device for precast component assembly includes a hoisting frame 1, two support beams 2, a hoisting assembly 3, and an anti-sway assembly 4. The upper end of the hoisting frame 1 is connected to the hoisting equipment, and two sliders 11 are slidably connected to the bottom of the hoisting frame 1 along its length. The upper end of the sliders 11 is fixed to the bottom of the hoisting frame 1 by fasteners. The lower end of the sliders 11 is rotatably fitted with a rotating cylinder 12 through a rotating shaft. The rotating cylinder 12 is fixed to the sliders 11 by fasteners. The lower end of the rotating cylinder 12 is fixedly connected to the top of the support beams 2. Thus, the position of the two support beams 2 on the hoisting frame 1 and the rotation angle of the support beams 2 relative to the hoisting frame 1 can be adjusted according to the hoisting requirements of the precast components. In this embodiment, the fasteners are bolts.
[0022] The hoisting assembly 3 is set on the support beam 2 and is used to connect with the prefabricated lifting ring on the prefabricated component. The middle of the hoisting frame 1 extends horizontally and is fixed with a horizontal extension rod 5 by bolts. The position of the extension rod 5 on the hoisting frame 1 is adjustable. One end of the anti-sway assembly 4 is fixedly connected to the end of the extension rod 5, and the other end of the anti-sway assembly 4 is detachably connected to the surface of the prefabricated component.
[0023] With the above setup, before lifting, the lifting assembly 3 is connected to the lifting ring on the component. Then, one end of the anti-sway assembly 4 is placed against the surface of the precast component to reduce the swaying of the precast component during lifting. When the precast component is moved above the designated position and the ground staff comes into contact with the precast component, the anti-sway assembly 4 can be separated from the precast component. The ground staff can then make minor adjustments to the placement of the precast component before lowering it down. Thus, by setting the anti-sway assembly 4, the swaying amplitude of the component during lifting can be reduced, improving construction safety.
[0024] Reference Figure 2 The anti-sway component 4 includes a connecting rod 41, an adjusting rod 42, an elastic rod 43, and a support plate 44. The upper end of the connecting rod 41 is fixed to the end of the extension rod 5. The connecting rod 41 is hollow inside and open at the bottom. The adjusting rod 42 slides through the inner cavity of the connecting rod 41 and its lower end extends out. A positioning component 45 for positioning is provided between the adjusting rod 42 and the connecting rod 41. The upper end of the elastic rod 43 has a receiving groove for the lower end of the adjusting rod 42 to slide through. The lower end of the adjusting rod 42 slides through the receiving groove. A spring 46 is fixedly connected in the receiving groove. One end of the spring 46 is welded to the bottom of the receiving groove, and the other end of the spring 46 is welded to the end of the adjusting rod 42.
[0025] The support plate 44 has a disc-shaped structure, and the upper end of the support plate 44 is ball-jointed to the lower end of the elastic rod 43. The support plate 44 abuts against the upper surface of the precast component. The part of the support plate 44 that contacts the precast component can be made of rubber. By connecting the support plate 44 to the elastic rod 43 by ball joint, the support plate 44 can adapt to the surface of different components, and under the action of the spring 46, it can better abut against the component and reduce the swing amplitude of the component.
[0026] With the above settings, the lengths of the adjusting rod 42 and the connecting rod 41 are adjusted according to the distance between the hoisting frame 1 and the component, and the support plate 44 is pressed against the surface of the component, so that the spring 46 is compressed. Then, the position of the adjusting rod 42 is fixed by the positioning component 45, thereby reducing the swing amplitude of the component.
[0027] Reference Figure 2The positioning assembly 45 includes a positioning rod 451 fixedly connected to the adjusting rod 42. The positioning rod 451 is perpendicular to the adjusting rod 42. The connecting rod 41 has a strip-shaped hole 452 along its length for the positioning rod 451 to extend from its inner cavity. The side wall of the strip-shaped hole 452 has multiple positioning grooves 453 communicating with it. The positioning grooves 453 communicate with the inner cavity of the connecting rod 41, and the multiple positioning grooves 453 are equidistantly distributed along the opening direction of the strip-shaped hole 452. In order to enable the positioning rod 451 to be engaged in the positioning groove 453, the adjusting rod 42 has a circular cross-section, and the inner cavity of the connecting rod 41 has a circular cross-section, so that the adjusting rod 42 can not only slide in the inner cavity of the connecting rod 41, but also rotate, so that the positioning rod 451 can be rotated and engaged in any one of the positioning grooves 453.
[0028] In order to make the positioning rod 451 more stably located in the positioning groove 453, an arc-shaped limiting groove is provided on the inner wall of the positioning groove 453 away from the spring 46. So after the positioning rod 451 moves into the positioning groove 453, due to the elastic force of the spring 46, the positioning rod 451 can be stably locked in the limiting groove, preventing the positioning rod 451 from coming out of the positioning groove 453.
[0029] In another embodiment of this application, considering that some components have asymmetrical shapes, the surface of the components may be placed at an angle in a designated position. In order to prevent the support plate 44 from slipping off the component, connecting ropes (not shown in the figure) are fixed on both sides of the outer surface of the support plate 44. The workers can tie the ends of the two connecting ropes to the hanging rings on both sides of the component, thereby reducing the probability of the support plate 44 falling off the component.
[0030] Reference Figure 3 To accommodate components of different shapes and sizes, two lifting assemblies 3 are installed on a support beam 2, located at opposite ends of the support beam 2. Each lifting assembly 3 includes a telescopic block 31, a motor 32, a take-up roller, and a lifting rope 33. The support beam 2 has a through groove along its length, through which the telescopic block 31 slides and passes. One end of the telescopic block 31 extends out of the through groove and is fixed to the motor 32 with bolts. The output shaft of the motor 32 is coaxially fixed to the take-up roller. One end of the lifting rope 33 is fixedly connected to the side wall of the take-up roller and wound around its outside. The other end of the lifting rope 33 is fixed with a hook, which can be connected to a lifting ring on the precast component. It should be noted that in this embodiment, a through hole is required at the end of the telescopic block 31 for the lifting rope 33 to pass through. By controlling the motor 32, the motor 32 adjusts the extension length of the lifting rope 33 via the take-up roller to accommodate the lifting requirements of different precast components.
[0031] Regarding the fixing method between the telescopic block 31 and the support beam 2, the following is configured: a screw 34 is threaded through the support beam 2 near its end. The end of the screw 34 extends into a through groove and abuts against the side wall of the telescopic block 31, thereby fixing the position of the telescopic block 31 according to the hoisting requirements. To reduce the displacement of the telescopic block 31 and enable the screw 34 to abut against the side wall of the telescopic block 31 more stably, a corrugated groove 35 is provided on the side wall of the telescopic block 31 facing the screw 34. The screw 34 abuts against the corrugated groove 35, further restricting the movement of the telescopic block 31 and enabling the hoisting assembly 3 to stably lift the prefabricated component.
[0032] It should be noted that the lifting frame 1 of this application is applicable to small lifting equipment, and the connection between the lifting frame 1 and the boom of the existing lifting equipment can be fixed by bolts. Moreover, those skilled in the art are capable of selecting a suitable connection method based on the existing construction and assembly methods, so this application will not elaborate on this.
[0033] 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.
