Description

Technical Field

[0001] This invention relates to the field of building curtain wall construction technology, and in particular to a unitized curtain wall assembly device for curtain wall engineering construction. Background Technology

[0002] In modern high-rise and super high-rise buildings, unitized curtain walls are widely used due to their advantages such as high degree of prefabrication in factories, fast on-site installation, and easy quality control. On the construction site, prefabricated unitized curtain wall panels (usually rectangular frame structures) need to be transported from the ground or within the building to designated locations on the exterior facade, and then precisely aligned and temporarily fixed. This process is called unitized curtain wall assembly. This process is typically carried out at high altitudes, is technically challenging, and requires extremely high levels of safety, efficiency, and precision.

[0003] Currently, common unitized curtain wall assembly devices typically include a track system located at the floor edge, a traveling trolley that can move along the track, and a hoisting mechanism mounted on the traveling trolley for lifting and adjusting the unitized panels. The hoisting mechanism generally includes a lifting unit and lifting devices for connecting the unitized panels. The basic working principle of existing devices is: the panels are horizontally transported to the vicinity of the installation area via the track system, and then the hoisting mechanism is used for vertical lifting, positioning, and hole alignment.

[0004] However, the existing unitized curtain wall assembly devices do not have a transfer mechanism for the unitized curtain wall, which makes it inconvenient to move the unitized curtain wall to the edge of the floor and is not conducive to the hoisting of the unitized curtain wall. Summary of the Invention

[0005] The purpose of this invention is to provide a unitized curtain wall assembly device for curtain wall engineering construction, which aims to solve the technical problem that existing unitized curtain wall assembly devices do not have a transfer mechanism for the unitized curtain wall, making it inconvenient to move the unitized curtain wall to the edge of the floor and hindering the hoisting of the unitized curtain wall.

[0006] To achieve the above objectives, the present invention provides a unitized curtain wall assembly device for curtain wall engineering construction. The unitized curtain wall assembly device includes a prefabricated base frame, a moving platform, a pushing component, and a support frame. The prefabricated base frame is installed inside the floor, and a portion of the prefabricated base frame extends to the outside of the floor edge. The moving platform is slidably mounted on the upper surface of the prefabricated base frame. The pushing component is also mounted on the prefabricated base frame for pushing the moving platform to slide on the prefabricated base frame. The support frame is mounted on the upper surface of the moving platform. The end of the support frame near the moving platform is a connecting section, and the end of the support frame away from the moving platform is a placement section. The connecting section is connected to the moving platform, and the placement section is used to place the unitized curtain wall.

[0007] The assembled base frame includes an anti-slip pad, a base plate, and two sliding guide rails. The anti-slip pad is provided at the bottom of the base plate, and the sliding guide rails are provided on both sides of the upper surface of the base plate. The moving platform is slidably arranged between the two sliding guide rails. The pushing component is installed between the two sliding guide rails, and the output end of the pushing component is connected to the bottom of the moving platform.

[0008] The mobile platform has sliding feet on both sides of its bottom, and sliding wheels on the bottom of each sliding foot. Each sliding guide rail has multiple ball bearings on both sides inside, and the ball bearings are in contact with the side of the sliding foot.

[0009] The two sliding guide rails are provided with limit grooves on the side away from the drive component, and limit plates are provided on both sides of the moving platform. The limit plates are in clearance fit with the limit grooves.

[0010] The drive assembly includes a drive motor, a threaded rod, and a ball screw nut assembly. The drive motor is mounted on the upper surface of the base plate and located at one end of the base plate away from the floor edge. The output end of the drive motor is provided with the threaded rod, and the ball screw nut assembly is provided on the threaded rod. The ball screw nut assembly is connected to the bottom of the moving platform.

[0011] The base plate is provided with a counterweight on its upper surface. The counterweight is located at one end of the base plate away from the floor edge. An auxiliary support is provided at the end of the threaded rod away from the drive motor. One end of the auxiliary support is located outside the threaded rod, and the other end of the auxiliary support is fixed above the base plate.

[0012] The auxiliary support includes a fixing block, a support block, and a support ring. The fixing block is provided at one end of the support block, and the support ring is provided at the other end of the support block. The support ring is located outside the threaded rod, and the fixing block is connected to the upper surface of the base plate.

[0013] The unitized curtain wall assembly device for curtain wall construction also includes two first protective plates. Each end face of the sliding guide rail is provided with a first protective plate. Both sides of the moving platform are provided with first through slots, and the first protective plates are fitted with the corresponding first through slots with clearance.

[0014] The unitized curtain wall assembly device for curtain wall construction also includes a second protective plate and two side plates.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] First embodiment: Please see Figures 1 to 5 ,in Figure 1 This is a structural schematic diagram of the unitized curtain wall assembly device for curtain wall construction according to the first embodiment. Figure 2 yes Figure 1 A magnified view of the local structure at point A. Figure 3 yes Figure 1 Another structural diagram from the perspective of Figure 4 yes Figure 3 A magnified view of the local structure at point B. Figure 5 This is a schematic diagram of the mobile platform in the first embodiment.

[0027] This invention provides a unitized curtain wall assembly device for curtain wall construction: it includes a prefabricated base frame, a moving platform 101, a pushing component, and a support frame 102. The prefabricated base frame includes an anti-slip pad 103, a base plate 104, and two sliding guide rails 105. The driving component includes a drive motor 106, a threaded rod 107, and a ball screw and nut assembly 108. This solution solves the problem that existing unitized curtain wall assembly devices lack a transfer mechanism for the unitized curtain walls, making it inconvenient to move the unitized curtain walls to the floor edge and hindering their hoisting. It is understood that the aforementioned solution can be applied to the structure of unitized curtain wall assembly devices for curtain wall construction.

[0028] In this specific embodiment, the prefabricated base frame is installed inside the floor, with a portion extending to the outside of the floor edge. A moving platform 101 is slidably mounted on the upper surface of the prefabricated base frame. A pushing component is also mounted on the prefabricated base frame, used to push the moving platform 101 to slide on the prefabricated base frame. A support frame 102 is mounted on the upper surface of the moving platform 101. One end of the support frame 102 near the moving platform 101 is a connecting section 109, and the other end away from the moving platform 101 is a placement section 110. The connecting section 109 is connected to the moving platform 101, and the placement section 110 is used to place the unitized curtain wall. By installing the prefabricated base frame inside the floor and extending its front end to the outside of the floor edge, the moving platform 101, driven by the pushing component, can support the support frame 102, which holds the unitized curtain wall, and allow it to slide along the prefabricated base frame. During operation, the unitized curtain wall is loaded inside the floor onto the placement section 110 of the support frame 102. Then, the moving platform 101 is pushed forward, transporting the unitized curtain wall together with the placement section 110 of the support frame 102 to the external end of the prefabricated base frame that is cantilevered out of the floor. This allows the unitized curtain wall to be safely and accurately moved automatically out of the building outline without relying on other hoisting or handling equipment, and directly to the predetermined lifting position on the outside of the building. This greatly facilitates the subsequent vertical lifting operation carried out by the hoisting mechanism.

[0029] The base plate 104 is provided with an anti-slip pad 103 at its bottom, and sliding guide rails 105 are provided on both sides of the upper surface of the base plate 104. The moving platform 101 is slidably arranged between the two sliding guide rails 105. The pushing component is installed between the two sliding guide rails 105, and the output end of the pushing component is connected to the bottom of the moving platform 101.

[0030] In this embodiment, the sliding guide rails 105 ensure the stability and straightness of the mobile platform 101 when it moves horizontally along the floor direction. The pushing component located between the sliding guide rails 105 directly drives the mobile platform 101 to slide between the two sliding guide rails 105, achieving efficient and direct power transmission. At the same time, the anti-slip pads 103 effectively increase the friction between the prefabricated base frame and the floor, preventing the prefabricated base frame from accidentally sliding or displacing.

[0031] Secondly, the bottom of the mobile platform 101 is provided with sliding feet 111 on both sides, and sliding wheels 112 are provided at the bottom of the sliding feet 111. Multiple balls 113 are provided on both sides inside the sliding guide rail 105, and the balls 113 are in contact with the side of the sliding feet 111.

[0032] In this embodiment, the sliding wheel 112 is responsible for bearing the main vertical load and achieving efficient rolling, while the ball bearing 113 array distributed on the side wall of the sliding guide rail 105 is in close contact with the side of the sliding foot 111, which effectively limits the lateral swaying or displacement of the moving platform 101 on the horizontal plane, and greatly reduces the lateral frictional resistance during the sliding process through point contact.

[0033] Meanwhile, each of the two sliding guide rails 105 is provided with a limiting groove 114 on the side away from the driving component, and each of the two sides of the moving platform 101 is provided with a limiting plate 115, and the limiting plate 115 is clearance-fitted with the limiting groove 114.

[0034] In this embodiment, the limiting plate 115 and the limiting groove 114 are provided to prevent the mobile platform 101 from falling off the sliding guide rail 105.

[0035] In addition, the drive motor 106 is mounted on the upper surface of the base plate 104 and located at one end of the base plate 104 away from the edge of the floor. The output end of the drive motor 106 is provided with the threaded rod 107, and the threaded rod 107 is provided with the ball screw nut pair 108. The ball screw nut pair 108 is connected to the bottom of the moving platform 101.

[0036] In this embodiment, the drive motor 106 is started, which drives the threaded rod 107 to rotate. Since the ball screw nut pair 108 is connected to the bottom of the moving platform 101, the moving platform 101 is driven to slide between the two sliding guide rails 105.

[0037] Furthermore, a counterweight 116 is provided on the upper surface of the base plate 104. The counterweight 116 is located at one end of the base plate 104 away from the floor edge. An auxiliary support is provided at one end of the threaded rod 107 away from the drive motor 106. One end of the auxiliary support is located outside the threaded rod 107, and the other end of the auxiliary support is fixed above the base plate 104.

[0038] In this embodiment, the counterweight 116 is positioned at one end of the base plate 104 near the interior of the floor, effectively balancing the enormous overturning moment generated when the mobile platform 101 carries the unit curtain wall forward to the exterior of the floor, preventing the front end of the device from tilting or the entire device from becoming unstable. Simultaneously, the auxiliary support provides an additional fulcrum for the threaded rod 107, reducing the deflection and vibration of the long cantilevered threaded rod 107 during load-bearing and transmission, ensuring transmission accuracy and lifespan.

[0039] Furthermore, the auxiliary support includes a fixing block 117, a support block 118, and a support ring 119. The fixing block 117 is provided at one end of the support block 118, and the support ring 119 is provided at the other end of the support block 118. The support ring 119 is located outside the threaded rod 107, and the fixing block 117 is connected to the upper surface of the base plate 104.

[0040] In this embodiment, both the fixing block 117 and the support ring 119 are fixedly connected to the support block 118. When preparing the auxiliary support, it is made using an integral molding technology, resulting in a more robust structure.

[0041] When using the unitized curtain wall assembly device for curtain wall construction in this embodiment, the prefabricated base frame is installed inside the floor and its front end extends to the outside of the floor edge. On the prefabricated base frame, the drive motor 106 is started, which drives the threaded rod 107 to rotate. Since the ball screw nut pair 108 is connected to the bottom of the moving platform 101, the moving platform 101 is driven to slide between the two sliding guide rails 105, thereby causing the support frame 102 on which the unitized curtain wall is placed to slide along the prefabricated base frame. During operation, the unitized curtain wall is loaded inside the floor onto the placement section 110 of the support frame 102. Then, the moving platform 101 is pushed forward, transporting the unitized curtain wall together with the placement section 110 of the support frame 102 to the external end of the prefabricated base frame that is cantilevered out of the floor. This allows the unitized curtain wall to be safely and accurately moved automatically out of the building outline without relying on other hoisting or handling equipment, and directly to the predetermined lifting position on the outside of the building. This greatly facilitates the subsequent vertical lifting operation carried out by the hoisting mechanism.

[0042] Second embodiment: Based on the first embodiment, please refer to Figure 6 and Figure 7 , Figure 6 This is a structural schematic diagram of the unitized curtain wall assembly device for curtain wall construction according to the second embodiment.

[0045] In this embodiment, the first protective plate 201 installed on the end face of the sliding guide rail 105 is always inserted into the first through groove 204 and slides therewith. The first protective plate 201 can prevent external debris from entering the interior of the sliding guide rail 105.

[0046] The threaded rod 107 is provided with side plates 203 on both sides, and the second protective plate 202 is provided at the top between the two side plates 203. The moving platform 101 is provided with a second through groove 205 through the middle, and the second protective plate 202 and the second through groove 205 are fitted with a clearance.

[0047] In this embodiment, the second protective plate 202 covering the threaded rod 107 always passes through the second through slot 205 when the moving platform 101 moves. With the cooperation of the two side plates 203, it can prevent excessive external dust from adhering to the threaded rod 107 and affecting the operation of the drive assembly.

[0048] When using the unitized curtain wall assembly device for curtain wall construction in this embodiment, the first protective plate 201 installed on the end face of the sliding guide rail 105 is always inserted into the first through groove 204 and slidably engaged with it. The first protective plate 201 can prevent external debris from entering the interior of the sliding guide rail 105. The second protective plate 202 covering the threaded rod 107 always passes through the second through groove 205 when the moving platform 101 moves. With the cooperation of the two side plates 203, it can prevent excessive external dust from adhering to the threaded rod 107 and affecting the operation of the drive assembly.
