Description

Technical Field

[0001] This utility model relates to the field of building curtain wall construction technology, and more specifically, it relates to a hoisting device for building curtain walls. Background Technology

[0002] In building curtain wall construction, suction cups are key components of hoisting devices, often used to fix and lift curtain wall panels. However, in actual projects, after prolonged use, suction cups may experience weakened suction force due to wear, decreased sealing performance, or other problems, and may even become unusable. Therefore, suction cups need to be disassembled, replaced, or maintained regularly to ensure the safety and stability of hoisting operations. However, in existing technologies, the disassembly and reinstallation of suction cups is often quite complex, involving multiple tools and operating steps. This is not only time-consuming and labor-intensive, but may also adversely affect the project progress.

[0003] On the other hand, in complex construction site environments and when time is tight, the rapid disassembly and installation of suction cups is particularly important. However, existing hoisting devices usually lack specially designed quick-assembly and disassembly structures, and their connection methods mostly rely on bolts or fasteners. When replacing suction cups, operators need to loosen and tighten multiple parts one by one, which increases labor costs and operational difficulty. Such a design cannot meet the requirements of modern construction for high efficiency and high safety. Therefore, there is an urgent need for a convenient and efficient solution to optimize the disassembly and installation process of suction cups and improve construction efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for a building curtain wall, comprising a mounting frame, a hoisting mechanism on the mounting frame, the hoisting mechanism comprising a connecting frame, a hook, a support rod, and a suction cup, the connecting frame being rotatably mounted on the mounting frame, the hook being disposed at the top of the connecting frame and connected to external hoisting equipment, the support rod being provided with multiple sets mounted on a mounting plate, the suction cup being mounted on the support rod by means of a quick-installation mechanism, the quick-installation mechanism comprising an insert rod, an outer sleeve, a sliding rod, a slider, a locking block, a locking groove, and a locking mechanism, the insert rod being mounted at the top of the suction cup, the outer sleeve being mounted on the bottom surface of the support rod, the sliding rod being provided with multiple sets mounted inside the outer sleeve, the slider being slidably mounted on the outer wall of the multiple sets of sliding rods, and the locking groove being disposed on the outer wall of the insert rod and adapted to the multiple sets of locking blocks.

[0008] The present invention is further configured such that the locking mechanism includes a connecting block, a transmission sleeve, a connecting groove, an arc plate, and a rotating sleeve. The connecting block is installed on the bottom surface of multiple sets of sliders, the transmission sleeve is slidably installed on the outer sleeve, the connecting groove is disposed on the top surface of the transmission sleeve and is slidably connected to multiple sets of connecting blocks, the arc plate is installed on the outside of multiple sets of transmission sleeves, and the rotating sleeve is rotatably installed on the outside of the outer sleeve.

[0009] The present invention is further configured such that the outer walls of the multiple sets of arc-shaped plates are provided with external threads, and the outer wall of the rotating sleeve is provided with internal threads and is threadedly connected to the multiple sets of arc-shaped plates. The threaded connection design realizes flexible control of the slider. By simply rotating the rotating sleeve, the locking or releasing operation of the block can be completed, which greatly reduces the difficulty of operation. At the same time, the stability and reliability of the threaded transmission further improve the safety and service life of the device.

[0010] The present invention is further configured such that a positioning groove is provided at the top of the insertion rod, and multiple sets of positioning grooves are provided; a positioning block is provided at the top of the outer sleeve, and multiple sets of positioning blocks are provided and adapted to multiple sets of positioning grooves. The multi-set structural design of positioning grooves and positioning blocks ensures that the insertion rod can be quickly and accurately aligned in the position inside the outer sleeve, simplifies the installation process of the suction cup, improves installation efficiency and reliability, reduces errors in the installation process, and enhances the stability and ease of operation of the overall device.

[0011] The present invention is further configured such that multiple sets of sliding rods are inclinedly arranged inside the outer sleeve. The inclined arrangement of the rods cleverly transforms the sliding motion of the slider into the inward closing or outward unfolding of the locking block, thereby realizing the efficient locking and releasing function of the insertion rod.

[0012] The present invention is further configured such that each of the multiple sets of sliding rods is provided with a limiting strip on its outer side, and the multiple sets of limiting strips are slidably connected to the multiple sets of sliders respectively. The limiting strips ensure that the movement of the slider on the sliding rod is controlled, avoiding the problem that the block and the slot cannot be accurately engaged due to movement deviation, thereby further improving the working accuracy and reliability of the device.

[0013] The present invention is further configured such that a tension spring is connected between the bottom surface of each of the multiple sets of sliders and the inner wall of the outer sleeve. The tension spring enables the slider to automatically return to its original position, ensuring that the locking block can be quickly reset or unfolded during installation and disassembly, which greatly improves the operating efficiency and ease of use of the device, while reducing the complexity of manual operation.

[0014] The present invention is further configured such that a sliding groove is provided on the outer wall of the outer sleeve, and a limiting rod is installed in the sliding groove. The transmission sleeve is slidably connected to the limiting rod. The design of the sliding groove and the limiting rod ensures that the movement direction of the transmission sleeve is controlled, avoids the transmission sleeve from deviating or becoming inaccurate during the sliding process, thereby improving the accuracy of the slider drive and ensuring the stable operation of the device.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a hoisting device for building curtain walls, which has the following beneficial effects:

[0017] 1. The beneficial effects of the hoisting mechanism are that by rotating the connecting frame onto the mounting frame, the entire hoisting mechanism can be adjusted in multiple directions around the mounting frame, thereby achieving the function of quickly adjusting the hoisting angle and direction to adapt to the hoisting needs of different curtain wall panels. In addition, the hook is set at the top of the connecting frame and connected to external hoisting equipment such as a crane to provide stable hoisting power for the device. The support rod serves as the installation base for the suction cups, and the reasonable layout of its multiple suction cups not only improves the stable hoisting effect of the building curtain wall, but also allows for flexible adjustment according to the shape and center of gravity of the curtain wall, thereby meeting the needs of different hoisting scenarios.

[0018] 2. The beneficial effects of the quick-installation mechanism are that the connection between the insertion rod at the top of the suction cup and the outer sleeve makes the installation and removal of the suction cup more convenient. The cooperation between the positioning block and the positioning groove can quickly and accurately adjust the installation position of the insertion rod. The slider slides along the inclined sliding rod, allowing the locking block to move inward and lock into the locking groove on the outer wall of the insertion rod, thereby completing the stable fixation of the suction cup. The tension spring ensures that the slider is always in an appropriate pre-tight state, improving the firmness of the suction cup installation. In addition, the sliding connection between the limiting strip and the slider further restricts the range of motion of the slider, improving the stability and safety of the quick-installation mechanism.

[0019] 3. The beneficial effect of the locking mechanism is that the threaded engagement between the rotating sleeve and the arc plate enables the driving and control of the slider. When the rotating sleeve rotates, it drives the transmission sleeve to slide along the limit rod, and through the sliding connection between the connecting block and the slider, the slider moves along the slide rod. In this way, the movement of the slider directly drives the locking block to engage or disengage with the insertion rod, thereby realizing the quick locking or unlocking operation of the suction cup. This structural design simplifies the installation and disassembly process of the suction cup, not only saving time but also reducing the difficulty of operation, and greatly improving construction efficiency and on-site operation safety.

[0029] Please see Figures 1-5 A hoisting device for a building curtain wall includes a mounting frame 1, on which a hoisting mechanism is provided. The hoisting mechanism includes a connecting frame 2, a hook 3, a support rod 4, and a suction cup 5. The connecting frame 2 is rotatably mounted on the mounting frame 1. The hook 3 is located at the top of the connecting frame 2 and connected to external hoisting equipment. The support rod 4 is provided with multiple sets mounted on the mounting plate. The suction cup 5 is mounted on the support rod 4 through a quick-installation mechanism. The quick-installation mechanism includes an insert rod 6, an outer sleeve 7, a sliding rod 8, a slider 9, a locking block 10, a locking groove 11, and a locking mechanism. The insert rod 6 is mounted at the top of the suction cup 5. The outer sleeve 7 is mounted on the bottom surface of the support rod 4. Multiple sets of sliding rods 8 are provided and mounted inside the outer sleeve 7. The slider 9 is slidably mounted on the outer wall of the multiple sets of sliding rods 8. The locking groove 11 is located on the outer wall of the insert rod 6 and is adapted to the multiple sets of locking blocks 10.

[0030] The top of the insertion rod 6 is provided with a positioning groove 17, and there are multiple sets of positioning grooves 17. The top of the outer sleeve 7 is provided with a positioning block 18, and there are multiple sets of positioning blocks 18 that are adapted to multiple sets of positioning grooves 17. When the insertion rod 6 is inserted into the outer sleeve 7, the positioning of the insertion rod 6 in the outer sleeve 7 is achieved by the engagement of the positioning block 18 with the positioning groove 17, so as to prevent the insertion rod 6 from shifting or loosening during the installation process.

[0031] Multiple sets of sliding rods 8 are inclinedly arranged inside the outer sleeve 7, so that the slider 9 can slide along the inclined sliding rods 8. During the sliding process, the slider 9 undergoes inward or outward horizontal displacement, thereby causing the locking block 10 to move closer or unfold.

[0032] Each of the multiple sliding rods 8 has a limiting strip 19 on its outer side. The multiple limiting strips 19 are slidably connected to the multiple sliding blocks 9, which restricts the movement direction of the sliding blocks 9, so that the sliding blocks 9 can only move along the set trajectory on the sliding rods 8, and avoids misalignment between the locking block 10 and the locking slot 11 due to deviation.

[0033] Multiple sets of sliders 9 are connected to the inner wall of the outer sleeve 7 by tension springs 20. The elastic tension of the tension springs 20 keeps the sliders 9 in a certain pre-tight state. When the locking block 10 is engaged, the tension springs 20 can provide a return force so that the sliders 9 can be quickly unfolded when disassembly is required.

[0034] The outer wall of the outer sleeve 7 is provided with a sliding groove 21, and a limiting rod 22 is installed in the sliding groove 21. The transmission sleeve 13 is slidably connected to the limiting rod 22. The sliding groove 21 provides a guide path for the limiting rod 22. The transmission sleeve 13 can move freely along the direction of the sliding groove 21 by slidingly connecting with the limiting rod 22, thereby realizing the driving control of the slider 9.

[0035] In this embodiment, the connecting frame 2 is rotatably mounted on the mounting frame 1, allowing the entire hoisting mechanism to be adjusted in multiple directions around the mounting frame 1, facilitating quick adjustment of the hoisting angle and direction. The hook 3 is connected to the top of the connecting frame 2 and is connected to external hoisting equipment such as a crane to provide hoisting power for the entire device. The support rod 4 serves as the mounting base for the suction cups 5, on which multiple sets of suction cups 5 are mounted. Through reasonable layout, stable hoisting of the building curtain wall is achieved. The position of the support rod 4 can be flexibly adjusted according to the shape and center of gravity of the curtain wall. The suction cups 5 are mounted on the support rod 4 through a quick-installation mechanism for adsorbing and fixing the curtain wall, thereby providing reliable gripping force during hoisting. The suction cups 5 can... Vacuum technology achieves strong adsorption on the surface of the curtain wall panel, effectively preventing slippage. When the suction cup 5 needs to be installed, the insertion rod 6 is inserted into the outer sleeve 7. The installation position of the insertion rod 6 is adjusted by the positioning block 18 and the positioning groove 17. Then, the rotating sleeve 16 is rotated to connect with the outer wall of multiple sets of arc plates 15 by threads and cooperate, driving the transmission sleeve 13 to slide along the limiting rod 22. The transmission sleeve 13 pushes multiple sets of sliders 9 to slide along the sliding rod 8. At the same time, the connecting block 12 slides along the connecting groove 14. The slider 9 slides along the obliquely installed sliding rod 8 to move inward and push the locking block 10 to lock into the locking groove 11, so that the insertion rod 6 is locked and fixed by multiple sets of locking blocks 10, completing the installation of the suction cup 5.

[0036] Please see Figures 2-5 As one embodiment of the locking mechanism: the locking mechanism includes a connecting block 12, a transmission sleeve 13, a connecting groove 14, an arc plate 15, and a rotating sleeve 16. The connecting block 12 is installed on the bottom surface of multiple sets of sliders 9, the transmission sleeve 13 is slidably installed on the outer sleeve 7, the connecting groove 14 is provided on the top surface of the transmission sleeve 13 and is slidably connected to the multiple sets of connecting blocks 12, the arc plate 15 is installed on the outside of the multiple sets of transmission sleeves 13, and the rotating sleeve 16 is rotatably installed on the outside of the outer sleeve 7.

[0037] The outer walls of multiple sets of arc plates 15 are provided with external threads, and the outer wall of the rotating sleeve 16 is provided with internal threads and is threadedly connected to the multiple sets of arc plates 15. When the rotating sleeve 16 rotates, it can drive the arc plates 15 and the connected transmission sleeve 13 to move axially through the threaded transmission, thereby further controlling the sliding of the slider 9.

[0038] More specifically, when it is necessary to disassemble the suction cup 5, the rotating sleeve 16 is rotated in the opposite direction. The rotating sleeve 16 and the arc plate 15 are engaged in reverse threaded connection. Then, the transmission sleeve 13 is driven to slide downward along the limiting rod 22. In this way, the transmission sleeve 13 pulls multiple sets of sliders 9 to slide along the slide rod 8, so that they gradually unfold outward, causing multiple sets of locking blocks 10 to move out of the locking slot 11. This releases the locking and fixing of the insertion rod 6 and completes the disassembly of the suction cup 5.

[0039] In summary, during use or operation of the overall equipment: the connecting frame 2 is rotatably mounted on the mounting frame 1, allowing the entire hoisting mechanism to be adjusted in multiple directions around the mounting frame 1, facilitating quick adjustments to the hoisting angle and direction. The hook 3 is connected to the top of the connecting frame 2 and is connected to external hoisting equipment such as a crane to provide hoisting power for the entire device. The support rod 4 serves as the mounting base for the suction cups 5, on which multiple sets of suction cups 5 are installed. Through reasonable layout, stable hoisting of the building curtain wall is achieved. The position of the support rod 4 can be flexibly adjusted according to the shape and center of gravity of the curtain wall. The suction cups 5 are installed on the support rod 4 through a quick-installation mechanism to adsorb and fix the curtain wall, thereby providing reliable gripping force during hoisting. The suction cup 5 can achieve strong adsorption on the surface of the curtain wall panel through vacuum technology, effectively preventing slippage. When the suction cup 5 needs to be installed, the insertion rod 6 is inserted into the outer sleeve 7. The installation position of the insertion rod 6 is adjusted by the positioning block 18 and the positioning groove 17. Then, the rotating sleeve 16 is rotated to connect with the outer wall of multiple sets of arc plates 15 by threads and cooperate, driving the transmission sleeve 13 to slide along the limiting rod 22. The transmission sleeve 13 pushes multiple sets of sliders 9 to slide along the slide rod 8. At the same time, the connecting block 12 slides along the connecting groove 14. The slider 9 slides along the obliquely installed slide rod 8 to move inward and push the locking block 10 to lock into the locking groove 11, so that the insertion rod 6 is locked and fixed by multiple sets of locking blocks 10, completing the installation of the suction cup 5.

[0040] When it is necessary to disassemble the suction cup 5, rotate the rotating sleeve 16 in the opposite direction. The rotating sleeve 16 and the arc plate 15 are engaged in reverse threaded connection. Then, the transmission sleeve 13 is driven to slide down along the limit rod 22. The transmission sleeve 13 pulls multiple sets of sliders 9 along the slide rod 8, so that they gradually unfold outward, causing multiple sets of locking blocks 10 to move out of the locking slot 11. This releases the locking and fixing of the insertion rod 6 and completes the disassembly of the suction cup 5.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
