Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a hoisting and docking device for preventing displacement of prefabricated building components. Background Technology

[0002] Precast components refer to various building parts that are prefabricated in a factory or on-site and then transported to the construction site for installation and assembly. They are the core components of prefabricated buildings. Through standardized design and industrialized production, they have replaced the traditional on-site casting construction method and have advantages such as stable quality, high construction efficiency, energy saving and environmental protection. In building construction, the hoisting and docking of precast components is an important construction link, and its docking accuracy directly affects the quality and safety of the building.

[0003] Currently, due to the large dimensions and small cross-sections of components such as PCF panels, PC panels, stairs, balconies, and precast composite floor slabs, the positions and spacing of the lifting points for various components differ. In order to ensure that the components are lifted horizontally and vertically, and that the lifting points are subjected to vertical force, direct lifting often cannot meet the requirements. Moreover, the position of the pre-embedded lifting lugs is prone to deviation. When lifting precast components, the posture of the precast components will be different from the posture when they are installed and fixed, which will bring difficulties to the installation and fixing of the components and seriously affect the construction quality of the project. In addition, because the steel wire is stretched at an angle during lifting, the components are not subjected to vertical force, which may cause the lifting lugs to fall off and the lifted components to be damaged.

[0004] The existing patent (publication number: CN205675990U) relates to the field of building construction, specifically a precast building component hoisting device. This device includes a main steel wire rope, a hoisting beam, and component steel wire ropes. Its key feature is that the hoisting beam has two rows of aligned hoisting holes along its length. The lower end of the main steel wire rope is movably connected to the upper row of hoisting holes on the hoisting beam, and the upper end of the component steel wire rope is movably connected to the lower row of hoisting holes on the hoisting beam. By setting a hoisting beam with two rows of hoisting holes on the hoisting device, the vertical force at the hoisting point can be ensured, and the tension angle of the steel wire rope on the component can be adjusted more precisely. This allows for adjustment of the posture of the hoisted component during lifting, making it easier to hoist the precast component into position and preventing damage during hoisting, thus ensuring hoisting quality and improving component installation efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing hoisting devices typically lack clamping and positioning structures for prefabricated components when hoisting them. Consequently, prefabricated components are prone to shifting during hoisting and docking, causing inconvenience to the docking work. Furthermore, existing hoisting devices are generally not convenient for arbitrarily adjusting the hoisting and docking position according to the length of different prefabricated components, resulting in poor flexibility and convenience in use.

[0006] To address this, a hoisting and docking device for prefabricated building components designed to prevent displacement is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A precast building component hoisting and docking device for preventing displacement includes a sling 1, a hanger 2 fixedly connected to the bottom of the sling 1, clamping and positioning components 3 provided on the front and rear sides of the bottom of the hanger 2, and a hoisting and attaching component 4 provided on the bottom of the hanger 2.

[0029] The clamping and positioning assembly 3 includes two first L-shaped frames 31, which are fixedly connected to the front and rear sides of the bottom of the hanger 2, respectively. An electric lifting air rod 32 is fixedly connected to the opposite side of the top of each of the two first L-shaped frames 31. The output rod of the electric lifting air rod 32 passes through the first L-shaped frame 31 and is fixedly connected to a second L-shaped frame 33. An electric clamping air rod 34 is fixedly connected to the bottom of the opposite side of each of the two second L-shaped frames 33. The output rod of the electric clamping air rod 34 passes through the second L-shaped frame 33 and is fixedly connected to a clamping plate 35.

[0030] In this embodiment: by setting up sling 1, hanger 2, clamping and positioning component 3, and lifting and attaching component 4, in use, the sling 1 can be lifted by the lifting equipment to achieve the lifting work. The hanger 2 provides a lifting support foundation for the clamping and positioning component 3 and the lifting and attaching component 4. The clamping and positioning component 3 can clamp and position the prefabricated component when lifting it, which can prevent the prefabricated component from shifting during docking, thus bringing convenience to the docking work. The lifting and attaching component 4 can be used to lift and attach the prefabricated component to be lifted, and the position of the lifting and attaching can be easily adjusted according to the length of different prefabricated components, thereby improving the flexibility and convenience of use.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the hoisting and mounting assembly 4 includes a fixed housing 41, which is fixedly connected to the bottom of the hanger 2. A forward and reverse motor 42 is fixedly connected to the right side of the fixed housing 41. A bidirectional screw 43 is fixedly connected to the output shaft of the forward and reverse motor 42. The left side of the bidirectional screw 43 extends through to the left side of the fixed housing 41. The side of the surface of the bidirectional screw 43 near the inner wall of the fixed housing 41 is rotatably connected to the inner wall of the fixed housing 41 through a bearing.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, both sides of the surface of the bidirectional screw 43 are connected to internal thread blocks 44 by threads. The two internal thread blocks 44 are slidably connected to the inner wall of the fixed housing 41 on one side of the fixed housing 41 respectively. The bottom of the two internal thread blocks 44 is fixedly connected to the lifting rope 45, and the bottom of the lifting rope 45 is fixedly connected to the hook 46.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, a limiting guide rod 47 is fixedly connected to the bottom right side of the inner wall of the fixed housing 41. The left side of the limiting guide rod 47 passes through two internal threaded blocks 44 in sequence and is fixedly connected to the bottom left side of the inner wall of the fixed housing 41. The inner walls of the two internal threaded blocks 44 are slidably connected to the surface of the limiting guide rod 47.

[0034] In this embodiment: by setting up a fixed housing 41, a forward and reverse motor 42, a bidirectional screw 43, internal thread blocks 44, lifting ropes 45, hooks 46, and limiting guide rods 47, in use, the positions of the two lifting ropes 45 and hooks 46 can first be adjusted according to the length of the prefabricated component. By starting the forward and reverse motor 42, the output shaft of the forward and reverse motor 42 drives the bidirectional screw 43 to rotate in the forward or reverse direction. Through the forward or reverse rotation of the bidirectional screw 43, the two internal thread blocks 44 can be simultaneously pushed into the inner cavity of the fixed housing 41 by the action of the threads. Moving in opposite or relative directions, the two internal threaded blocks 44 will drive the two lifting ropes 45 and hooks 46 to move in opposite or relative directions respectively. This allows the positional spacing of the two lifting ropes 45 and hooks 46 to be adjusted arbitrarily according to the length of different precast components, improving the flexibility and convenience of use. Then, the two hooks 46 on the two lifting ropes 45 are respectively hooked to the reserved hanging rings of the precast components, so that the precast components can be hoisted and subsequently connected for installation. The limiting guide rod 47 can guide and limit the two internal threaded blocks 44 and provide auxiliary support.

[0035] Specifically, such as Figure 5As shown, each of the two first L-shaped frames 31 has a first through hole 5 on an opposite side of its top, which is used in conjunction with the two electric lifting air rods 32. The output rod surface of the electric lifting air rod 32 is slidably connected to the inner wall of the first through hole 5.

[0036] Specifically, such as Figure 5 As shown, the bottom of the two second L-shaped frames 33 on opposite sides is provided with a second through hole 6 for use with the two electric clamping air rods 34. The output rod surface of the electric clamping air rod 34 is slidably connected to the inner wall of the second through hole 6.

[0037] In this embodiment: by providing a first through hole 5, the output rod of the electric lifting air rod 32 can pass through the first L-shaped frame 31 for telescopic output; by providing a second through hole 6, the output rod of the electric clamping air rod 34 can pass through the second L-shaped frame 33 for telescopic output.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, rubber pads 7 are fixedly connected to the opposite sides of the two clamping plates 35, and anti-slip textures are provided on the opposite sides of the two rubber pads 7.

[0039] Specifically, such as Figure 1 As shown, from left to right, the top of the hanger 2 is fixedly connected to a remote control box 8 and a battery box 9, which are used in conjunction with the clamping and positioning assembly 3 and the hoisting and attaching assembly 4.

[0040] In this embodiment: by setting the rubber pad 7, damage to the rigid clamping of the precast component by the two clamping plates 35 can be avoided, and the clamping friction can be increased. By setting the remote control box 8, the clamping positioning component 3 and the hoisting and attaching component 4 can be remotely controlled. By setting the battery box 9, power can be provided to the clamping positioning component 3 and the hoisting and attaching component 4.

[0041] Working Principle: In use, the positions of the two lifting ropes 45 and hooks 46 can be adjusted according to the length of the precast component. This can be achieved by starting the forward / reverse motor 42, which drives the bidirectional screw 43 to rotate in either direction. This rotation of the bidirectional screw 43 causes the two internal threaded blocks 44 to move simultaneously in opposite directions within the cavity of the fixed housing 41. The two internal threaded blocks 44 then drive the two lifting ropes 45 and hooks 46 to move in opposite directions, allowing for arbitrary adjustment of the distance between the two lifting ropes 45 and hooks 46 according to the length of different precast components. This improves flexibility and convenience. Finally, the two hooks 46 on the two lifting ropes 45 are connected to the pre-installed hanging rings on the precast component, enabling the lifting equipment to hoist the component. The sling 1 is used for lifting, which allows for the hoisting of precast components and subsequent docking and installation. During the hoisting of the precast components, two electric lifting air rods 32 are activated, causing their output rods to drive two second L-shaped frames 33 downwards. The two second L-shaped frames 33 then drive two clamping plates 35 downwards via two electric clamping air rods 34, adjusting the clamping plates 35 to a suitable height. Then, by activating the two electric clamping air rods 34, their output rods drive the two clamping plates 35 to move in opposite directions until the rubber pads 7 on the clamping plates 35 are tightly fitted with the precast components. This clamping and positioning of the precast components prevents them from shifting during docking, facilitating the docking process.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
