Description

Technical Field

[0001] This invention relates to the field of construction platform technology, and more specifically to a cantilevered push-pull platform for the construction of fourth-generation residential rooftop gardens. Background Technology

[0002] The sky gardens of fourth-generation residences feature an alternating layout of odd and even floors, with floor heights exceeding 6 meters, twice that of traditional floor heights. These new structural features present new construction challenges. Construction of the sky garden's ceiling and exterior walls requires working at heights. Conventional aerial work platforms such as scissor lifts cannot be used due to balcony load limitations; instead, scaffolding at least 4.5 meters high must be erected.

[0003] While existing scaffolding can help construction workers build the rooftop and exterior walls of the rooftop garden, its application requires on-site setup and dismantling, which not only extends the construction period but also incurs additional costs. Furthermore, due to the limited space in the rooftop garden, there are certain safety hazards for construction workers using the scaffolding, resulting in unsatisfactory construction outcomes.

[0004] To address this, we propose a cantilevered push-pull platform for the construction of fourth-generation residential rooftop gardens. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a cantilevered push-pull platform for the construction of fourth-generation residential rooftop gardens.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cantilevered push-pull platform for the construction of a fourth-generation residential rooftop garden, comprising a working platform and guide rails set on both sides below the working platform, and a support component including a base set below the end of the guide rail away from the working platform, threaded posts fixed to both ends of the top side of the base, an installation block movably sleeved on the outside of the threaded posts and fixed on the adjacent guide rail for adjusting the height of the guide rail, and nuts set on both sides of the installation block and threaded onto the outer wall of the adjacent threaded posts for fixing the position of the installation block. The guide rail is provided with an adjusting component for adjusting the position of the working platform, and the top side of the working platform is provided with a guardrail for preventing construction personnel from falling off the working platform. Through the operation of the above components, construction personnel can conveniently carry out construction on the rooftop garden's canopy and exterior walls, and the height of the guide rails and the working platform can be adjusted according to installation requirements.

[0007] Furthermore, the adjusting component includes a lead screw located below the guide rail and multiple drive blocks that are threaded onto the outside of the lead screw and fixed to the bottom side of the work platform for moving the work platform. The drive blocks are movably fitted onto the outside of the guide rail. A movable plate is provided between the guide rail and the base. Rollers are fixed at both ends of the bottom side of the movable plate. The base has through holes corresponding to the rollers. A screw rod with its bottom end rotatably connected to the top side of the base is threaded through the middle of the movable plate for moving the movable plate vertically. Through the operation of the above components, the position of the work platform can be adjusted, making it convenient for construction personnel to install the guide rail on the windowsill.

[0008] Furthermore, a loading block is fixed to the bottom side of the guide rail on the outside of the lead screw. One end of the lead screw is rotatably connected to the inner wall of the loading block near the working platform. The other end of the lead screw passes through the outside of the loading block away from the working platform and is fixed with a second drive block that drives the lead screw to rotate. A handle is fixed to the end of the second drive block away from the lead screw. A bolt is threaded through the second drive block. A threaded hole is opened at the end of the loading block near the second drive block. One end of the bolt is threaded into the inside of the threaded hole. Through the operation of the above components, the second drive block and the lead screw can be locked, improving the stability of the lead screw.

[0009] Furthermore, the guardrail includes handrails installed on both sides of the work platform and above the end away from the base, multiple connecting rods one installed below the handrails and fixed to the top side of the work platform, a receiving groove opened at the top of the connecting rod one, and a connecting rod two slidably inserted into the receiving groove. The ends of the connecting rod two located outside the receiving groove are fixed to the adjacent handrails. Bolts two are bolted through the top of the connecting rod one located at both ends of the handrail. Multiple threaded holes two are opened on the side of the connecting rod two near the adjacent bolt two. One end of the bolt two is threaded into the adjacent threaded hole two. The guardrail can protect the construction personnel working on the work platform and prevent them from falling from the work platform. The height of the guardrail can be adjusted.

[0010] Furthermore, the drive block slides inside the loading block, and a transmission block movably sleeved on the outside of the lead screw is slidably connected inside the loading block at the end away from the working platform. A gear is fixedly sleeved on the outer wall of the top of the screw, and a rack block is fixed on one side of the gear and meshes with the transmission block to drive the gear to rotate. A fixed block is movably sleeved on the outside of the lead screw and fixed inside the loading block on the side of the transmission block away from the working platform. A spring movably sleeved on the outside of the lead screw is fixed between the fixed block and the transmission block. Through the operation of the above components, the screw can be driven to rotate.

[0011] Furthermore, the top end of the screw is rotatably connected to a fixing block fixed on an adjacent guide rail for stabilizing the screw. The fixing block can improve the stability of the screw.

[0012] Furthermore, the top of the threaded post one is provided with a threaded groove, and the threaded post two with a support fixed at the top is threadedly inserted into the threaded groove. One side of the threaded post one is provided with a limiting post one fixed to the bottom side of the support. The bottom end of the limiting post one is provided with a sliding groove, and the limiting post two is slidably inserted into the sliding groove. The outer side of the threaded post one is provided with a plurality of limiting holes opened on the top side of the mounting block around the threaded post one as the center. The bottom end of the limiting post two is slidably inserted into the adjacent limiting hole. With the support of the support and the base, the guide rail and the working platform can be further stabilized on the windowsill.

[0013] Furthermore, a rotating hole is provided at the end of the loading block away from the working platform, and the lead screw slides through the inside of the rotating hole. The rotating hole can prevent the loading block from interfering with the rotation of the lead screw.

[0014] Furthermore, the movable plate has connecting holes at both ends, and the threaded post 1 slides through the connecting holes. Through the connecting holes, the threaded post 1 can be prevented from interfering with the vertical displacement of the movable plate.

[0015] Furthermore, the handrail at one end of the work platform is positioned between the handrails on both sides of the work platform. By positioning the handrail at one end of the work platform between the handrails on both sides, the handrails, connecting rod one, and connecting rod two enclose the platform on three sides, forming a continuous protective barrier that effectively prevents construction workers from falling from the edge of the work platform.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention facilitates the construction of the rooftop garden's canopy and exterior walls, avoiding the need for extensive secondary scaffolding erection, shortening the construction period, improving safety, and reducing costs. It allows for adaptive adjustments based on the height of the window sills for different apartment types, making it convenient for construction workers to install the cantilevered sliding platform. Furthermore, the position of the cantilevered sliding platform can be easily adjusted according to construction needs, ensuring high flexibility in its use.

[0017] 2. This invention can protect construction workers on the work platform, preventing them from falling off the platform. It has high protective performance, and the height of the guardrail can be adjusted according to the height of the window. Furthermore, the platform is stabilized on the windowsill through the end support of the bracket and base, improving the stability of the windowsill and ensuring high safety performance.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Combination Figure 1This embodiment describes a cantilevered push-pull platform for the construction of a fourth-generation residential rooftop garden. It includes a working platform 1 and guide rails 2 positioned on both sides below the working platform 1. Support components include a base 3 positioned below the end of the guide rails 2 furthest from the working platform 1; threaded posts 4 fixed to both ends of the top side of the base 3; mounting blocks 5 movably sleeved on the outside of the threaded posts 4 and fixed to the adjacent guide rails 2 for adjusting the height of the guide rails 2; and nuts 6 positioned on both sides of the mounting blocks 5 and threaded onto the outer walls of the adjacent threaded posts 4 for fixing the position of the mounting blocks 5. The guide rails 2 are equipped with adjusting components for adjusting the position of the working platform 1. The top side of the working platform 1 is equipped with a guardrail to prevent construction workers from falling off the working platform 1.

[0022] The implementation principle of a cantilevered push-pull platform for the construction of a fourth-generation residential rooftop garden in this embodiment is as follows: When construction of the rooftop garden's ceiling and exterior walls is required, the height of the guide rail 2 is adjusted according to the height of the window sill wall. The nut 6 is rotated, and through the threaded engagement between the nut 6 and the threaded post 4, the nut 6 is displaced. After the nut 6 separates from the mounting block 5, the guide rail 2 is pulled, and through the sliding engagement between the mounting block 5 and the threaded post 4, the guide rail 2 is displaced vertically. After the height adjustment of the guide rail 2 is completed, the nut 6 is rotated, and through the threaded engagement between the nut 6 and the threaded post 4, the nut 6 is displaced. When the nut 6 abuts against the mounting block 5... Afterwards, guide rail 2 is installed on the windowsill. Pushing guide rail 2 will move guide rail 2 and work platform 1 through the window to the outside. Then, base 3 is fixed on the indoor ground. After that, the construction workers, after fastening their safety belts, climb onto work platform 1 through the window to carry out construction work on the roof and exterior walls of the rooftop garden. After the construction is completed, the work platform 1 is returned to the indoors by reversing the operation. When the construction workers need to adjust the position of work platform 1 during the construction process, the operation of the adjusting mechanism can move work platform 1. The guardrail can protect the construction workers on work platform 1 and prevent them from falling from work platform 1.

[0023] Example 2: Combination Figure 2 and Figure 4This embodiment, based on Embodiment 1, further improves upon the following: the adjusting component includes a lead screw 14 disposed below the guide rail 2 and multiple drive blocks 15 threadedly sleeved outside the lead screw 14 and fixed to the bottom side of the working platform 1 for moving the working platform 1. The drive blocks 15 are movably sleeved outside the guide rail 2. A movable plate 20 is provided between the guide rail 2 and the base 3. Rollers 21 are fixed at both ends of the bottom side of the movable plate 20. The base 3 has through holes 22 corresponding to the rollers 21. A threaded hole is threaded through the middle of the movable plate 20, and the bottom end is rotatably connected to the top side of the base 3 for moving the movable plate 20 vertically. Move screw 23 and rotate lead screw 14. Through the threaded engagement of lead screw 14 and drive block 15, the working platform 1 can be moved. At this time, the position of the working platform 1 can be adjusted. When it is necessary to move guide rail 2, the rotation of screw 23 drives the movable plate 20 to move, and drives the roller 21 on the movable plate 20 to move. When the roller 21 passes through the through hole 22 and abuts against the indoor ground and the base 3 is separated from the indoor ground, the construction personnel can easily push guide rail 2. Through the rotation of roller 21, guide rail 2 is moved, which makes it convenient for the construction personnel to set up guide rail 2 on the windowsill.

[0024] Example 3: Combination Figure 7 This embodiment, based on embodiment 2, further improves upon the following: A loading block 35 is fixed to the bottom side of the guide rail 2 on the outside of the lead screw 14. One end of the lead screw 14 is rotatably connected to the inner wall of the loading block 35 near the working platform 1. The other end of the lead screw 14 extends through to the outside of the loading block 35 away from the working platform 1 and is fixed with a second driving block 25 that drives the lead screw 14 to rotate. A handle 26 is fixed to the end of the second driving block 25 away from the lead screw 14, and a bolt is threaded through the second driving block 25. One end of the loading block 35 near the drive block 25 has a threaded hole. One end of the bolt 27 is threaded into the threaded hole. The cooperation between the bolt 27 and the threaded hole can lock the drive block 25 and the lead screw 14, improving the stability of the lead screw 14. When the lead screw 14 needs to be rotated, the bolt 27 is rotated to move the bolt 27. After the bolt 27 is disengaged from the threaded hole, the handle 26 is rotated to rotate the drive block 25 and the lead screw 14.

[0025] Example 4: Combination Figure 3 and Figure 8This embodiment, based on embodiment 1, further improves upon the following: the guardrail includes handrails 28 positioned on both sides of the work platform 1 and above the end furthest from the base 3; multiple connecting rods 29 positioned below the handrails 28 and fixed to the top side of the work platform 1; a receiving groove 30 opened at the top of the connecting rod 29; and connecting rods 31 slidably inserted into the receiving groove 30. The ends of connecting rods 31 located outside the receiving groove 30 are fixed to adjacent handrails 28. Bolts 32 are bolted through the tops of connecting rods 29 at both ends of the handrails 28. Multiple threaded holes 33 are opened on the side of connecting rods 31 near the adjacent bolts 32. One end of the bolt is threaded into the adjacent threaded hole 33. When the construction workers are setting up the work platform 1, they can adjust the height of the guardrail according to the height of the window. By rotating the bolt 32, the bolt 32 will be displaced. After the bolt 32 is disengaged from the threaded hole 33, the handrail 28 will be pulled. Through the sliding fit between the connecting rod 31 and the receiving groove 30, the handrail 28 and the connecting rod 31 will be displaced vertically. At this time, the height of the guardrail can be adjusted. After the height of the guardrail is adjusted, the bolt 32 will be rotated and displaced. When the bolt 32 is inserted into the adjacent threaded hole 33, the height of the guardrail will be fixed.

[0026] Example 5: Combination Figure 6 This embodiment, based on embodiment 2, further improves upon the following: the drive block 15 slides inside the loading block 35; a transmission block 16, movably sleeved on the outside of the lead screw 14, is slidably connected inside the loading block 35 at the end away from the working platform 1; a gear 24 is fixedly sleeved on the outer wall of the top end of the screw 23; a rack block 19, fixed on the transmission block 16 and meshing with the gear 24 to drive the gear 24 to rotate, is provided on one side of the gear 24; a fixed connecting block 17, movably sleeved on the outside of the lead screw 14 and fixed inside the loading block 35, is provided on the side of the transmission block 16 away from the working platform 1; and the fixed connecting block 17 and the transmission block 19... A spring 18 is fixed between blocks 16 and movably sleeved outside the lead screw 14. When the screw 23 needs to be rotated, the handle 26 is turned, which drives the second drive block 25 and the lead screw 14 to rotate. Through the threaded engagement between the lead screw 14 and the first drive block 15, the first drive block 15 can be moved toward the transmission block 16, which in turn moves the rack block 19. The displaced rack block 19 drives the gear 24 to rotate, which in turn drives the screw 23 to rotate, which in turn moves the movable plate 20, which in turn moves the roller 21 on the movable plate 20, which in turn moves the roller 21 through the through hole 22 and abuts against the indoor floor.

[0027] The top end of the screw 23 is rotatably connected to a fixing block 34 fixed on the adjacent guide rail 2 for stabilizing the screw 23. The fixing block 34 can improve the stability of the screw 23.

[0028] Example 6: Combination Figure 5 This embodiment, based on embodiment 1, further improves upon the following: A threaded groove 7 is provided at the top of the threaded post 4; a threaded post 8, with a support 9 fixed at its top, is threadedly inserted into the threaded groove 7; a limiting post 10, fixed to the bottom side of the support 9, is provided on one side of the threaded post 4; a sliding groove 11 is provided at the bottom of the limiting post 10; a limiting post 12 is slidably inserted into the sliding groove 11; multiple limiting holes 13, centered on the threaded post 4 and circumferentially arranged on the top side of the mounting block 5, are provided on the outer side of the threaded post 4; the bottom end of the limiting post 12 is slidably inserted into an adjacent limiting hole 13. When it is necessary to stabilize the guide rail 2 and the working platform 1... When the platform is on the windowsill, the limiting post 2 12 can be pulled to move it vertically. After the limited post 2 12 disengages from the limiting hole 13, the threaded post 2 8 can be rotated. Through the threaded engagement between the threaded post 2 8 and the threaded groove 7, the threaded post 2 8 can be moved vertically, which in turn moves the support 9 vertically. When the support 9 abuts against the wall at the top of the room, the limiting post 2 12 can be pulled to move it vertically. When the limited post 2 12 is inserted into the adjacent limiting hole 13, the threaded post 2 8 is locked. With the support of the support 9 and the base 3, the guide rail 2 and the working platform 1 can be further stabilized on the windowsill.

[0029] The loading block 35 has a rotating hole at the end away from the working platform 1. The lead screw 14 slides through the rotating hole. The rotating hole can prevent the loading block 35 from interfering with the rotation of the lead screw 14.

[0030] The movable plate 20 has connecting holes at both ends, and the threaded post 4 slides through the connecting holes. The connecting holes prevent the threaded post 4 from interfering with the vertical displacement of the movable plate 20.

[0031] The handrail 28 located at one end of the work platform 1 is set between the handrails 28 on both sides of the work platform 1. By setting the handrail 28 at one end of the work platform 1 between the handrails 28 on both sides, the handrail 28, connecting rod 1 29 and connecting rod 2 31 enclosed on three sides form a continuous protective barrier, effectively preventing construction workers from falling from the edge of the work platform.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
