Description

Technical Field

[0001] This utility model relates to the field of high-level curtain wall hoisting technology, specifically to a high-level curtain wall hoisting device. Background Technology

[0002] In the construction of curtain walls for high-rise and super high-rise buildings, the hoisting of components in high-altitude areas such as the tower crown is a critical step affecting project safety, efficiency, and cost. Therefore, developing a specialized hoisting equipment suitable for this scenario is essential. Currently, commonly used counterweight hoisting equipment, such as mobile jacks, requires the erection of a dedicated counterweight foundation on the roof, which presents problems such as large loads, cumbersome assembly and disassembly, and inconvenient relocation. While spider cranes are mobile and flexible, their rental costs are high, they have stringent requirements for roof load-bearing capacity and working space, and require specialized operators, making them difficult to adapt to the complex and ever-changing high-altitude working environment.

[0003] To address the aforementioned shortcomings, this invention provides a novel high-level curtain wall hoisting device that connects directly to the main steel beam via clamp kits, eliminating the need for additional counterweight foundations. It is easy to assemble and disassemble, and quick to move, ensuring safety and reliability while significantly reducing costs and labor dependence, greatly improving construction efficiency, and flexibly adapting to hoisting needs for various complex facade shapes. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-level curtain wall hoisting equipment that features a simple structure, convenient assembly and disassembly, no need for an independent counterweight foundation, and strong adaptability. It solves the problems of complex installation, high cost, difficult relocation, and inability to adapt to complex structural shapes of traditional high-level hoisting equipment.

[0005] (II) Technical Solution To achieve the aforementioned objectives of simple structure, convenient assembly and disassembly, no need for independent counterweight foundation, and strong adaptability, this utility model provides the following technical solution: a high-level curtain wall hoisting device, comprising: The support base is rigidly fixed to the main structural steel beam by at least one set of detachable clamp kits; The boom is fixedly connected to the front end of the support base; A pulley block is installed at the end of the boom; A winch is installed on the bracket base; A steel wire rope, one end of which is wound around the winch and the other end of which passes over the pulley block to form a lifting end.

[0006] Preferably, a leveling mechanism is provided between the main structural steel beam and the support base.

[0007] Preferably, the leveling mechanism includes a guide rail frame fixed to the lower part of the support base, at least one slider slidably disposed within the guide rail frame, and an adjusting rod threadedly connected to each slider and extending out of the support base. The adjusting rod controls the movement of the slider along the guide rail frame between the main structural steel beam and the support base. The upper surface of the slider is in close contact with the support base, and the lower surface of the slider is in close contact with the main structural steel beam.

[0008] Preferably, the slider is wedge-shaped, and the contact surface between the slider and the main structural steel beam is provided with anti-slip texture or elastic pad.

[0009] Preferably, a triangular support frame is connected between the bracket base and the boom.

[0010] Preferably, the triangular support frame, the bracket base, and the boom are connected by a flange.

[0011] Preferably, the control system of the winch integrates a weight sensor and an overload protection device.

[0012] Preferably, both the support base and the boom are welded from galvanized steel square tubing.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-level curtain wall hoisting device, which has the following beneficial effects: 1. This type of high-level curtain wall hoisting equipment uses clamp kits to directly and rigidly fix the support base to the main structural steel beams, eliminating the need for the additional counterweight foundation frame required by traditional counterweight hoisting equipment. This enables rapid assembly and disassembly and flexible relocation, effectively reducing construction costs and reliance on manual labor. At the same time, compared with large equipment such as spider cranes, this equipment has a simple structure, fewer erection restrictions, lower requirements for roof load-bearing capacity, and can be installed without professional operating qualifications, significantly saving construction costs and improving adaptability to complex facade shapes.

[0014] 2. This high-level curtain wall hoisting equipment overcomes the problem of frame tilting caused by uneven installation surfaces by setting a leveling mechanism between the main structural steel beam and the support base. The leveling mechanism consists of a guide rail frame, a wedge-shaped slider, and an adjusting rod. Rotating the adjusting rod drives the slider to move horizontally, utilizing the wedge-shaped inclined plane principle to convert horizontal displacement into vertical height adjustment of the support base, achieving multi-point, precise leveling. When the slider moves to the working position, its lower surface abuts against the main structural steel beam, and its upper surface abuts against the support base, forming stable support with self-locking characteristics, ensuring the hoisting system always maintains optimal vertical stress. Compared to traditional shim filling or ball joint adjustment methods, this purely mechanical leveling mechanism significantly improves installation accuracy and operational stability while possessing higher operational reliability and environmental adaptability, providing a substantial optimization for high-level curtain wall hoisting construction that is not available in existing clamp fixing methods.

[0017] 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.

[0018] Please see Figures 1-5This invention relates to a high-level curtain wall hoisting device, which mainly includes components such as a support base 1, a boom 3, a pulley block 4, a winch 5, and wire ropes 6. Specifically, the support base 1 and boom 3 are made of galvanized steel square tubing with a cross-sectional dimension of 100×100×5mm, which possesses good structural strength and corrosion resistance. The support base 1 is rigidly fixed to the main structural steel beam 2 by at least one set of detachable clamp kits 11. Specifically, this detachable rigid connection is achieved using clamp kits 11 with matching M20 screws. This connection method, which directly utilizes the existing structure as the load-bearing foundation, eliminates the drawbacks of traditional hoisting equipment requiring additional counterweight foundations or occupying a large working area, making the equipment flexible in assembly and disassembly and convenient in relocation, especially suitable for complex high-level operation scenarios such as tower crowns.

[0019] Please see Figures 1-5 The boom 3 is fixedly connected to the front end of the support base 1, and a pulley block 4 is installed at its end. To enhance structural stability, a triangular support frame 8 is connected between the support base 1 and the boom 3. The triangular support frame 8, the support base 1, and the boom 3 are preferably detachably connected by a flange and M16 high-strength bolts. This design not only facilitates quick assembly and adjustment on site, but also enhances the bending and torsional resistance of the overall structure. Using a flange connection is a conventional technique in this field, and the specific installation method is not shown in the figure. The winch 5 is installed on the support base 1. In this utility model, a JM3.0 type winch 5 is specifically used. Its control system integrates a weight sensor and an overload protection device, which can monitor the load in real time during the hoisting process and automatically limit overload operation, effectively improving operational safety. One end of the wire rope 6 is wound around the winch 5, and the other end passes around the pulley block 4 to form the lifting end, constituting a complete lifting transmission system. In this utility model, a wire rope 6 with a diameter of Φ12 is specifically used as the lifting load-bearing and force transmission component.

[0020] Please see Figures 2-3To further improve the adaptability and stability of equipment installation, this utility model provides a leveling mechanism 7 between the main structural steel beam 2 and the support base 1. The leveling mechanism 7 includes a guide rail frame 71 fixed to the lower part of the support base 1, at least one slider 72 slidably disposed in the guide rail frame 71, and an adjusting rod 73 threadedly connected to each slider 72 and extending out of the support base 1. The adjusting rod 73 is used to control the movement of the slider 72 along the guide rail frame 71 between the main structural steel beam 2 and the support base 1. The adjusting rod 73 can be externally connected to a handle for easy rotation, or a slot can be opened at the end for rotation with a screwdriver. The slider 72 is preferably wedge-shaped, with its lower surface in close contact with the main structural steel beam 2 and its upper surface in close contact with the support base 1. By rotating the adjusting rod 73, the slider 72 is driven to move horizontally inside the guide rail frame 71. The horizontal displacement is converted into vertical height adjustment using the wedge-shaped inclined plane principle, thereby achieving rapid and precise leveling of the support base 1 and ensuring close contact between the support base 1 and the main structural steel beam 2. In addition, the contact surface between the slider 72 and the main structural steel beam 2 can be provided with anti-slip textures or elastic pads to enhance friction, prevent slippage, and reduce damage to the steel beam surface. This purely mechanical leveling mechanism has a simple structure, intuitive operation, and high reliability. It effectively overcomes the defects of conventional rigid connections that easily lead to frame tilting and additional stress when the installation surface is uneven, ensuring that the hoisting system is always in the optimal stress state.

[0021] In summary, this high-level curtain wall hoisting equipment uses a clamp kit 11 to directly and rigidly fix the support base 1 to the main structural steel beam 2, eliminating the need for a counterweight foundation required by traditional counterweight hoisting equipment. This enables rapid assembly and disassembly and flexible transfer, reducing costs and reliance on manual labor. Furthermore, compared to equipment like spider cranes, it has a simpler structure, fewer installation restrictions, lower roof load-bearing requirements, and can be installed without professional qualifications, effectively reducing costs and improving adaptability to complex facades. Additionally, by adding a purely mechanical leveling mechanism 7 between the main structural steel beam 2 and the support base 1, consisting of a guide rail frame 71, a wedge-shaped slider 72, and an adjusting rod 73, it overcomes the defects of conventional rigid connections that easily tilt and generate additional stress when the installation surface is uneven. Compared to simple shims or ball joint adjustments, this mechanism can achieve multi-point, precise, and self-locking horizontal adjustment, ensuring the hoisting system is vertically stressed. This significantly improves the installation accuracy, overall stability, and safety reliability of the equipment under different construction conditions, providing a substantial optimization for existing simple hoisting devices that rely solely on clamp fixation.

[0022] In use, the support base 1, made of 100×100×5 galvanized steel square tubing, and the boom 3 are first transported to the work position and hoisted onto the main structural steel beam 2 for initial positioning. Next, the support base 1 is rigidly fixed to at least three main structural steel beams 2 (front, middle, and rear) using clamp kits 11 and M20 bolts, forming a stable load-bearing foundation. Then, the triangular support frame 8 connecting the support base 1 and the boom 3 is installed and securely connected to the base and boom 3 using flanges and M16 high-strength bolts to enhance the overall structure's resistance to lateral forces and overturning. Finally, the movable pulley block 4 is installed at the end of the boom 3 and secured with M16 high-strength bolts. Install the JM3.0 type winch 5 on the support base 1, and firmly connect it to the base with bolts. Connect its control system to the external power supply and operation signals. Then, perform the wire rope 6 winding operation: fix one end of the Φ12 wire rope 6 to the drum of the winch 5, and pass the other end through the movable pulley group 4 at the end of the boom 3 in sequence to form a lifting end that can be used to lift the curtain wall unit. If there is an unevenness on the main steel beam installation surface at the work site, the leveling mechanism 7 can be operated before tightening the clamp: by rotating the adjusting rod 73 extending from the support base 1, the wedge slider 72 is driven to slide horizontally in the guide rail frame 71. The inclined plane is used to make a fine adjustment of the height of the corresponding position of the base until the whole frame reaches a horizontal state, and then finally tighten the clamp screw. After all the installation is completed, the winch 5 is tested under no-load and load conditions to confirm that its weight sensor and overload protection function are normal, the wire rope 6 is wound correctly and without interference, and all connection parts are firm and reliable. Then the formal lifting operation can begin.
