Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a prefabricated composite plate hoisting device. Background Art

[0002] Composite slabs have been widely used and praised in the field of modern architecture. Composite slabs are a kind of building component that combines the efficient production of prefabricated slabs with the strong structural performance of cast-in-place reinforced concrete layers. It uses the prefabricated slabs as permanent formwork and then pours a layer of cast-in-place reinforced concrete on it to form a solid and flat integral floor slab. This design not only significantly improves the integrity and rigidity of the floor slab, ensuring the stability and safety of the structure in high-rise buildings and large-span buildings, but also greatly facilitates the subsequent finishing work due to the extreme flatness of the upper and lower surfaces, simplifies the construction process, and improves the overall aesthetics and comfort of the building.

[0003] During the installation of composite floor slabs, tower cranes are key lifting tools, and their operation is mainly limited to lifting in the vertical direction. This limitation poses a challenge to the precise installation of prefabricated composite panels. Since the existing lifting equipment structure only provides simple lifting functions and does not have the function of angle adjustment, it is difficult to accurately control the horizontal position, angle and rotation direction of prefabricated composite panels during the lifting process. Relying solely on tower cranes for direction adjustment during the lifting process increases the difficulty of installation. Improper operation may also cause collisions between prefabricated panels and surrounding structures, thereby damaging the molds on the edges or surfaces of prefabricated panels, burying quality risks for subsequent concrete pouring work, and ultimately affecting the overall sensory quality and structural safety of the building.

[0004] Based on this, it is necessary to study a prefabricated composite panel lifting equipment. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a prefabricated composite panel hoisting equipment, which is mainly used to hoist the composite panel into place. During the installation process of existing composite floor panels, tower cranes are mainly used as hoisting tools. The limitation of vertical hoisting significantly increases the difficulty of accurate installation of prefabricated composite panels. Traditional hoists lack angle adjustment function, which makes it difficult to accurately control the horizontal position, angle and rotation of prefabricated panels during hoisting. Over-reliance on tower cranes for direction adjustment is not only inefficient, but also easy to cause collisions with surrounding structures, damage prefabricated panels and molds, and bury hidden dangers for the subsequent concrete pouring quality.

[0024] like Figure 1-6 As shown in , an assembled composite plate lifting equipment includes a hanger 1, a hanging beam 2, a hanging rod 12, a guide block 3 and an adjustment component; this embodiment uses the hanger 1 as a fixed foundation, the two ends of the hanger 1 are isosceles trapezoidal structures, the upper part is a plate-like structure, the plate-like structure serves as a supporting foundation, the hanging beam 2 is slidable relative to the hanger 1, the hanging rod 12 is arranged on the hanging beam 2, and is directly connected to the composite plate hanging, and the hanging beam 2 is connected to the crane and is translated under the action of the crane. The purpose of this embodiment for lifting the composite plate is to enable one end of the composite plate to be tilted and moved according to demand, so as to adjust the tilt angle of the composite plate. The purpose of the adjustment is to adapt to different construction sites, avoid collisions between the composite plate and surrounding buildings, reduce the horizontal occupied area during the lifting process, and improve the flexibility of the lifting construction.

[0025] In order to achieve the above-mentioned purpose, the present embodiment is provided with inclined guide rails on both sides of the hanger 1, and guide blocks 3 are fixed at both ends of the hanging beam 2. The guide blocks 3 are adapted to be mounted in the guide rails and can slide along the guide rails; the upper connections of the hanging beams 2 on both sides are connected to independently working adjustment components so that the hanging beams 2 slide along the guide rails. The adjustment components can provide support force for the hanging beams 2 and keep the hanging beams 2 in the adjusted position; the hanger 1 is provided with a lifting ring connected to the crane.

[0026] In the specific structure, the hanger 1 includes an isosceles trapezoidal frame 102, a connecting frame 102 and a supporting hanger 103, wherein isosceles trapezoidal frames 102 are arranged at both ends of the connecting frame 101, and the isosceles trapezoidal frame 102 is provided with guide rails along its inclined surface direction, and the supporting hanger 103 is fixed to the upper part of the connecting frame, and a hanging seat is fixed on the supporting hanger 103, and a hanging hole is arranged on the hanging, and the hanging hole is connected to the crane through structures such as a hanging rope and a hook. Under the action of the crane, the hanger 1 is lifted, and the hanging beam 2 can slide along the guide rail relative to the hanger 1. During the sliding process of the hanging beam 2, the hanging rod 12 on one side is driven to move accordingly, so as to realize the adaptive adjustment of the hanging angle and size of the composite plate.

[0027] In order to ensure the lifting effect, in this embodiment, the suspension rod 12 is linearly arranged at the lower part of the suspension beam 2; a limiting plate is provided on the upper part of the suspension rod 12, the suspension rod 12 is slidably mounted on the suspension beam 2, and a hook is hinged at the lower part of the suspension rod 12; the opening of the hook faces outward, and multiple groups are symmetrically arranged.

[0028] The adjustment assembly includes a support rod 7, a support plate 8, an adjustment block 10, an adjustment seat 9 and an adjustment rod 11; an adjustment flat hole 6 is horizontally arranged on the hanger 1 and the adjustment seat 9, the support rod 7 passes through the adjustment flat hole 6, and a support plate 8 is fixed at its upper end; during implementation, the adjustment flat hole is an inclined long strip hole with a length, and the guide hole is specifically opened on the isosceles trapezoidal structure, the guide hole 4 is inclined downward and inwardly configured, and a guide block 3 is fixedly arranged at the end of the suspension beam 2, and the guide block 3 is a square structure in structure. The guide block 3 is adapted to be mounted in the guide hole 4 and can slide along the guide hole 4, and then when sliding, the suspension beam 2 moves along the guide hole 4, that is, tilted movement, and then the bottom of multiple suspension rods 12 is in a tilted movement state, that is, the composite plate is tilted and moved.

[0029] In structure Fig. 9 As shown in the figure, the guide block 3 is adapted to be mounted in the guide hole 4, and a positioning plate 5 is provided between the guide block 3 and the suspension beam. The positioning plate 5 is used to limit the position of the guide block, and the positioning plate 5 is fixedly connected to the guide block.

[0030] The two sides of the adjustment seat 9 are inwardly contracted inclined surfaces. The adjustment blocks 10 are arranged on both sides of the adjustment seat 9 and fit with the inclined surfaces on the corresponding sides respectively. The adjustment rod 11 is a reverse-threaded screw and is correspondingly reverse-threadedly connected to the adjustment blocks 10 on both sides. When the adjustment rod 11 is driven, the adjustment block 10 moves inward or outward, and uses the inclined surface to make the adjustment seat 9 move up and down along the inclined surface.

[0031] In this embodiment, the adjustment component adopts a horizontal reverse-threaded screw for adjustment. By adjusting the spacing of the adjustment block 10, the height is adjusted while meeting the support requirements, and combined with the structure of the adjustment flat hole 6, the position change of the suspension beam 2 is realized. That is, a strong support type vertical adjustment, a follow-up horizontal adjustment flat hole 6 and a guide hole 4 structure are adopted to realize the position change of the suspension beam 2. During the change process, the load is always borne by the support contact type adjustment block 10, the support strength is large, and the structural stability is good. The load of the composite plate is directly transmitted to the hanger 1 through the suspension beam 2, the support rod 7, the support plate 8, the adjustment seat 9 and the adjustment block 10.

[0032] In the specific structure, multiple adjusting rods 11 are arranged in parallel, and two adjusting rods 11 are rotatably arranged on the hanger 1 through the support. The driving ends of the multiple adjusting rods 11 are provided with driving wheels, and the driving wheels are provided with synchronous belts, and one of the driving wheels is connected to the driving motor. The synchronous rotation of the adjusting rods 11 is achieved through the synchronous belt, and then the adjusting block 10 is synchronously translated. The support plate 8, the support rod 7, the hanging beam 2 and the hanging rod 12 are the force-bearing bodies. After the support plate 8 is subjected to force, it directly contacts the adjustment seat 9 and applies force to the adjustment seat 9 from the top. In order to ensure the transmission of force, multiple groups of adjusting flat holes 6 and support rods 7 are correspondingly provided, and the upper ends of the multiple support rods 7 are fixed on the support plate 8, and the support plate 8 is located on the adjustment seat 9.

[0033] This embodiment has two main adjustment purposes during adjustment, namely, spacing adjustment and angle adjustment. During the spacing adjustment process, the adjusting rods 11 on both sides are adjusted synchronously so that the adjusting seats 9 on both sides can be adjusted vertically in a synchronous manner, that is, the suspension beams 2 are at the same level, but due to the constraints of the guide rails and the guide holes 4, the spacing of the suspension beams 2 on both sides is adaptively adjusted to adapt to composite plates of different sizes. During the angle adjustment process, the adjusting rods 11 on both sides are asynchronously moved, such as one is stationary and the other is moving, so that there is a difference in the movements of the adjusting rods 11 on both sides, so that the heights of the suspension beams 2 are at different heights. Under the limit of the guide hole 4, one end of the suspension rod 12 is low and the other end is high, that is, the composite plate is in an inclined state, and the degree of this inclination can be further adaptively adjusted according to needs.

[0034] When in use, the hanger 1 is hooked and connected to the crane, and the crane is started to transfer the hanger 1 to the upper part of the composite plate, the spacing of the suspension rod 12 is adjusted, the suspension rod 12 is hooked and connected to the lifting ring of the composite plate, and then the composite plate is lifted. During the lifting process, according to the actual working conditions, the adjustment rod 11 on one side is started to tilt the side so that the composite plate is in a tilted state; during the process of the composite plate being put into position, the composite plate 15 is put into position in a tilted state, one side of it first enters the installation area, and then the opposite side is adjusted to be put into position. The positioning method is simple, and compared with the traditional adaptive lifting, the difficulty of positioning is reduced.

[0035] Embodiment 2: This embodiment further illustrates the structure of the regulating component.

[0036] like Figure 8 As shown in the figure, another implementation of the adjustment component is provided in this embodiment, the adjustment component includes a lifting rope 17, a guide wheel 18 and a winch 19, the winch 19 leads out the lifting rope 17, the guide wheel 18 is installed on the hanger 1, and the lifting rope is fixedly connected to the suspension beam 2 after being guided by the guide wheel.

[0037] This embodiment adopts a soft lifting rope as the force-bearing basis, and uses the lifting rope to always provide a lifting basis for the lifting beam 2 to offset the load of the composite plate lifting; as the winch is sent and released, combined with the limit of the guide rail, the lifting beam 2 is tilted and displaced.

[0038] Embodiment 3: This embodiment further illustrates the specific implementation of the guide rail and the guide block 3.

[0039] like Figure 5 As shown in , in this embodiment, a guide hole 4 is provided in the guide rail, the guide block 3 is adapted to be nested in the guide hole 4, and a spring 16 is provided between the upper end of the guide hole 4 and the guide block 3. In this embodiment, a spring 16 is arranged between the guide hole 4 and the guide block 3, so that the guide block 3 slides under the dual action of gravity and the spring 16, ensuring the structural adjustment effect and smoothness.

[0040] Embodiment 4: This embodiment further stabilizes and strengthens the structure of the adjustment block 10.

[0041] When implementing Figure 5 As shown in , the adjusting block 10 is also provided with a positioning assembly, which is a positioning rod arranged on the adjusting block 10 or a positioning block arranged at the bottom of the adjusting block 10, and a positioning slot 13 adapted to the positioning block 14 is arranged on the hanging beam 2. This embodiment can enhance the stability of the translation of the adjusting block 10 through the positioning assembly, and ensure the reliability of the adjusting block 10 in vertically adjusting the adjusting seat 9.

[0042] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention.
