Description

Technical Field

[0001] This application relates to the field of building construction technology, specifically to a building curtain wall hoisting clamp and hoisting device. Background Technology

[0002] With the development of building technology, the importance of building curtain walls as the external envelope of buildings has become increasingly prominent. Building curtain walls not only fulfill the basic functions of sheltering from wind and rain and providing thermal insulation, but also greatly enhance the aesthetics of buildings through their unique decorative effects. Depending on the materials used, building curtain walls can be divided into various types, such as glass curtain walls, metal curtain walls, stone curtain walls, artificial panel curtain walls, and composite material curtain walls.

[0003] In the installation of building curtain walls, hoisting is a crucial step. Traditional hoisting methods typically involve clamping the building curtain wall with clamps, then connecting the clamps to the hook of a crane, and using the crane's lifting capacity to hoist the building curtain wall to the designated position.

[0004] Because building curtain walls, especially glass curtain walls, are heavy, construction workers often over-tighten the clamps to prevent them from falling off during hoisting. This practice may damage the curtain wall, affecting its structural integrity and aesthetics, and may even lead to its destruction. Utility Model Content

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] See Figure 1 , Figure 2 , Figure 3 This application provides a building curtain wall hoisting fixture, including a hoisting base 21, on which a main clamping plate 22 and a secondary clamping plate 23 are arranged opposite to each other. The side of the main clamping plate 22 facing the secondary clamping plate 23 is provided with a plurality of suction cups 24. It also includes a pressure sensor 25, the pressure-sensitive element 251 of the pressure sensor 25 is disposed on the side of the secondary clamping plate 23 facing the main clamping plate 22, and the hoisting base 21 is also provided with a first driving mechanism 26 for driving the main clamping plate 22 to move closer to or away from the secondary clamping plate 23.

[0054] Specifically, the lifting base 21 is used to install and support other components of the lifting clamp; the main clamping plate 22 and the auxiliary clamping plate 23 are both vertically arranged flat structures, arranged opposite each other on the left and right, forming a space between them for clamping and fixing the building curtain wall. For example, the main clamping plate 22 can be slidably connected to the lifting base 21, and the auxiliary clamping plate 23 can be fixedly connected to the lifting base 21. The first driving mechanism 26 is connected between the lifting base 21 and the main clamping plate 22 and is used to drive the main clamping plate 22 closer to or further away from the auxiliary clamping plate 23. Several suction cups 24 are fixed to the surface of the main clamping plate 22 facing the auxiliary clamping plate 23. The suction cups 24 are used to adhere to the building curtain wall; the more suction cups 24 there are, the greater the adhesion force to the building curtain wall.

[0055] A pressure sensor 25 is a device or apparatus that senses pressure signals and converts them into usable electrical signals according to a certain rule. The pressure sensor 25 typically consists of a pressure-sensitive element and a signal processing unit. When external pressure is applied to the pressure-sensitive element, the element deforms accordingly, or its electrical parameters change. This change is proportional to the applied pressure. The change in the pressure-sensitive element is converted into an electrical signal. The signal processing unit amplifies, filters, linearizes, and performs temperature compensation on the weak electrical signal output by the pressure-sensitive element to output a standard electrical signal on the display screen. The operator can directly read the pressure magnitude based on the value of this electrical signal. For example, the pressure-sensitive element 251 of the pressure sensor 25 is located on the side of the auxiliary clamping plate 23 facing the main clamping plate 22. When the main clamping plate 22 and the auxiliary clamping plate 23 are used to clamp the building curtain wall, the pressure-sensitive element 251 contacts the surface of the building curtain wall and deforms or its electrical parameters change under pressure. The signal processing unit of the pressure sensor 25 can be located on the hanging bracket 21 or on other structures connected to the lifting fixture.

[0056] During the installation of building curtain walls, the building curtain wall hoisting clamps provided in this application embodiment can clamp and fix the building curtain wall. The specific clamping and fixing process is as follows:

[0057] First, the first drive mechanism 26 is controlled to drive the main clamping plate 22 away from the secondary clamping plate 23 until the distance between the main clamping plate 22 and the secondary clamping plate 23 is greater than the thickness of the building curtain wall to be clamped. Then, the building curtain wall is placed between the main clamping plate 22 and the secondary clamping plate 23, and the first drive mechanism 26 is controlled to drive the main clamping plate 22 closer to the secondary clamping plate 23. During this process, several suction cups 24 are adsorbed on the surface of the building curtain wall, and the pressure sensor 25 monitors the clamping force of the main clamping plate 22 and the secondary clamping plate 23 on the building curtain wall in real time. When the clamping force reaches the set value range, the first drive mechanism 26 stops to prevent the main clamping plate 22 and the secondary clamping plate 23 from being over-clamped and damaging the building curtain wall.

[0058] The building curtain wall hoisting clamp provided in this application embodiment is powered by a first drive mechanism 26 and can clamp and fix the building curtain wall by cooperating with the main clamping plate 22 and the auxiliary clamping plate 23. By setting a number of suction cups 24 on the main clamping plate 22, the building curtain wall can be adsorbed, effectively reducing the clamping force required to clamp the building curtain wall and reducing the physical pressure on the building curtain wall. By setting a pressure sensor 25, the clamping force of the main clamping plate 22 and the auxiliary clamping plate 23 on the building curtain wall can be monitored in real time, which helps to prevent construction personnel from over-clamping during operation, thereby protecting the building curtain wall from damage.

[0059] Compared to existing technologies, this application, by enabling real-time monitoring of clamping force, allows operators to ensure that the building curtain wall is subjected to appropriate pressure during installation, reducing the risk of damage to the building curtain wall due to improper operation, improving construction safety, and also helping to extend the service life of the building curtain wall and reduce later maintenance costs by reducing unnecessary clamping force.

[0060] In some embodiments, see Figure 1 The bottom of the hanger 21 is provided with a mounting groove 211 with openings at both ends. The main clamping plate 22 and the auxiliary clamping plate 23 are disposed in the mounting groove 211. The main clamping plate 22 is connected to the groove wall on one side of the mounting groove 211 through the first drive mechanism 26, and the auxiliary clamping plate 23 is connected to the groove wall on the other side of the mounting groove 211. Accordingly, by placing the main clamping plate 22 and the auxiliary clamping plate 23 in the mounting groove 211, the overall structure is more compact and occupies less space. At the same time, it can also ensure the stability of the main clamping plate 22 and the auxiliary clamping plate 23 during use, reducing displacement or detachment caused by improper installation or external force.

[0061] For example, the first drive mechanism 26 includes a plurality of linear actuators, the two ends of which are connected to the groove wall of the mounting groove 211 and the main clamping plate 22, respectively. By controlling the extension or retraction of the linear actuators, the main clamping plate 22 is driven to move closer to or away from the auxiliary clamping plate 23. For example, the linear actuator may include a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc.

[0062] In some embodiments, see Figure 1 The secondary clamping plate 23 is connected to the groove wall of the mounting groove 211 through several damping buffers 28. Accordingly, when the building curtain wall is suspended in the air and affected by wind speed, the damping force generated by the several damping buffers 28 can reduce the resonance amplitude of the wind speed on the building curtain wall and improve the stability and safety of the building curtain wall hoisting.

[0063] In some embodiments, see Figure 1 , Figure 3The auxiliary clamping plate 23 has an anti-slip pad 27 on the side facing the main clamping plate 22. The anti-slip pad 27 can be fixed to the auxiliary clamping plate 23 using adhesive or bolts. A through hole is provided on the anti-slip pad 27 opposite the pressure-sensitive element 251, and the pressure-sensitive element 251 is disposed in this through hole. Accordingly, by providing the anti-slip pad 27, the friction between the auxiliary clamping plate 23 and the building curtain wall can be increased, preventing slippage between the auxiliary clamping plate 23 and the building curtain wall under pressure.

[0064] In some embodiments, see Figure 1 , Figure 2 The mounting bracket 21 is equipped with an air extraction mechanism 29 that communicates with the suction cup 24. Accordingly, when the suction cup 24 is attached to the surface of the building curtain wall, the air extraction mechanism 29 can extract the air from the suction cup 24 to create a negative pressure between the suction cup 24 and the building curtain wall, thereby further improving the suction force of the suction cup 24 on the building curtain wall.

[0065] For example, see Figure 1 The air extraction mechanism 29 includes an air pump 291 mounted on the mounting base 21. The air pump 291's extraction port is connected to all suction cups 24 via a pipe. For example, the air pump 291's extraction port is connected to one end of a telescopic tube 293, and the other end of the telescopic tube 293 is connected to each suction cup 24 via several branch pipes 292.

[0066] See Figure 4 This application also provides a building curtain wall hoisting device, including a hanger 1. Two hoisting clamps 2 are provided at the bottom of the hanger 1. The hoisting clamps 2 are the building curtain wall hoisting clamps provided in the above embodiments. The lifting base 21 of the hoisting clamp 2 is connected to the hanger 1.

[0067] During the installation of building curtain walls, the building curtain wall hoisting device provided in this application embodiment can hoist the building curtain wall into place. The specific hoisting and placement process is as follows:

[0068] First, assemble the crane on the external building, connect the crane hook to the gantry 1, and use two lifting clamps 2 to clamp and fix the building curtain wall to be installed; then, use the crane to lift the entire lifting device and the building curtain wall and position it in the installation position; after the building curtain wall is installed, separate the lifting clamps 2 from the building curtain wall, and then carry out the lifting of the next building curtain wall.

[0069] The building curtain wall hoisting device provided in this application embodiment, by using building curtain wall hoisting clamps, can monitor the clamping force in real time when clamping and fixing the building curtain wall. Operators can ensure that the building curtain wall is subjected to appropriate pressure during installation, reduce the risk of damage to the building curtain wall due to improper operation, improve construction safety, and also help extend the service life of the building curtain wall and reduce later maintenance costs by reducing unnecessary clamping force.

[0070] In some embodiments, see Figure 4 The hanger 1 is equipped with a second drive mechanism 3 that drives the two lifting clamps 2 to move closer or further apart. Accordingly, the second drive mechanism 3 can drive the two lifting clamps 2 to move closer or further apart, thereby adjusting the distance between the two lifting clamps 2 and enabling the lifting of building curtain walls of different sizes.

[0071] For example, the lifting bases 21 of the two lifting clamps 2 can be slidably installed on the bottom of the lifting frame 1. The second drive mechanism 3 may include two cylinders, which are set on the lifting frame 1 and are used to drive the two lifting clamps 2 to slide on the lifting frame 1 to adjust the distance between the two lifting clamps 2.

[0072] In some embodiments, see Figure 5 The second drive mechanism 3 includes a threaded rod 31 and two movable seats 32. The threaded rod 31 is rotatably connected to the hanger 1. The threaded rod 31 has two external threaded sections with opposite directions of rotation. The two movable seats 32 are respectively threaded onto the two external threaded sections. The lifting seats 21 of the two lifting clamps 2 are respectively connected to the two movable seats 32. In use, by rotating the threaded rod 31, the threaded rod 31 drives the two movable seats 32 to move closer or further apart, which in turn drives the two lifting clamps 2 to move closer or further apart, thereby adjusting the distance between the two lifting clamps 2 and realizing the hoisting of building curtain walls of different sizes.

[0073] For example, the movable base 32 and the lifting base 21 are detachably connected. This structure facilitates the removal of the lifting clamp 2 when needed, enabling quick assembly, disassembly, adjustment, and maintenance of the lifting clamp 2. For instance, the movable base 32 and the lifting base 21 are connected by fastening bolts 34. For easier control of the rotation of the threaded rod 31, see [reference needed]. Figure 5 One end of the threaded rod 31 is fixed with a torsion block 33. Accordingly, the torsion block 33 can act as a larger lever arm, allowing the operator to apply a larger torque when rotating the threaded rod 31, while reducing the required operating force and making it easier to control the rotation of the threaded rod 31.

[0074] In some embodiments, see Figure 4 The lifting frame 1 includes a crossbeam 11, lifting lugs 12, and two diagonal braces 13. The lifting lugs 12 are positioned above the crossbeam 11 and connected to both ends of the crossbeam 11 via the two diagonal braces 13. Two lifting clamps 2 are located at the bottom of the crossbeam 11. Accordingly, the crossbeam 11 and the two diagonal braces 13 form a triangular structure, which improves the robustness and stability of the lifting frame 1. The lifting lugs 12 are used to connect with the hook of the crane during lifting operations. Furthermore, a windproof net 14 is provided in the space between the crossbeam 11 and the two diagonal braces 13.

[0075] For example, the crossbeam 11 is a hollow structure, and the threaded rod 31 is disposed in the inner cavity of the crossbeam 11 and connected to the crossbeam 11 through two bearing structures so that the threaded rod 31 can rotate around its own axis. One end of the threaded rod 31 extends to the outside of the crossbeam 11 and is connected to the torsion block 33. The bottom of the crossbeam 11 is provided with a slide groove extending along its length direction. The movable seat 32 passes through the slide groove and is connected to the lifting seat 21 of the lifting clamp 2 disposed below the crossbeam 11. The movable seat 32 can slide along the slide groove.

[0076] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
