Description

Technical Field

[0001] This invention belongs to the field of lifting scaffolding technology, specifically relating to a super high-rise variable cross-section attached lifting scaffolding. Background Technology

[0002] With increasingly sophisticated construction techniques for super high-rise buildings, while ensuring functional and structural stability, higher demands are being placed on architectural art. Art and architecture have become integrated, representing a key development direction for urban beautification. To accentuate the building's form, variable cross-sections are often used, but these changes present significant challenges for external scaffolding protection. Traditional super high-rise construction often employs cantilevered steel pipe scaffolding as the working surface and external protective frame. This method is inefficient, unsafe, labor-intensive, and consumes a large amount of reusable materials. Furthermore, traditional attached lifting scaffolding cannot achieve variable cross-section climbing, resulting in low construction efficiency and high safety risks. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a super high-rise variable cross-section attached lifting scaffold, which enables the attached lifting scaffold to achieve variable cross-section climbing, thereby improving construction efficiency and construction safety.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention discloses a high-rise building variable cross-section attached lifting scaffold, comprising a scaffold body, a slide rail, and a wall-mounted support. The slide rail includes parallel uprights and several horizontal bars between the uprights. The scaffold body is fixed to the horizontal bars. The slide rail slides within the wall-mounted support. The wall-mounted support includes a U-shaped frame with arc-shaped guide rails arranged parallel between its two sides. The two ends of the arc-shaped guide rails are respectively fixed to the two sides of the U-shaped frame. Sliding columns are slidably mounted on the arc-shaped guide rails. Each end of the sliding column has a connecting shaft, and each connecting shaft has a hydraulic rod. One end of the hydraulic rod is hinged to the connecting shaft, and the other end is hinged to one side of the U-shaped frame. A through groove is provided in the middle of one side of the U-shaped frame, and a connecting plate is provided in the through groove. One end of the connecting plate is connected to the sliding column, and the other end of the connecting plate has a clamping block. The slide rail is slidably connected to the clamping block.

[0006] Furthermore, an installation ring is sleeved on the sliding column, and the connecting plate is fixedly connected to the installation ring. The installation ring is provided with a plurality of annularly distributed first limiting grooves, and the sliding column is provided with a plurality of second limiting grooves that match the first limiting grooves. At least one of the first limiting grooves is provided with a limiting block for limiting the relative rotation of the sliding column and the installation ring.

[0007] Furthermore, when the sliding column is located at the lowest point of the arc-shaped guide rail, the connecting plate is in a horizontal state.

[0008] Furthermore, the U-shaped frame has vertically arranged screws on its open side, with connecting blocks at both ends of the screws. The U-shaped frame has mounting grooves on both sides, which are slidably connected to the grooves. The connecting blocks can rotate vertically within the mounting grooves. A limiting ring is provided between the parallel screws, with the outer side of the limiting ring slidably connected to the screws. Locking nuts are provided on both sides of the connecting screws.

[0009] Furthermore, a pre-tensioning spring is provided in the mounting groove, with one end of the pre-tensioning spring fixed in the groove and the other end of the pre-tensioning spring fixed to the end of the connecting block.

[0010] Furthermore, permanent magnets are provided at the bottom of the second limiting groove and at both ends of the limiting block.

[0011] Furthermore, an annular cover plate is provided on the open end of the U-shaped frame.

[0012] Furthermore, a support column is provided on the side of the annular cover plate facing the clamping block. One end of the support column is rotatably connected to the annular cover plate in one direction, and the other end of the support column is located below the crossbar of the slide rail. A return spring is provided on the support column.

[0013] The beneficial effects of this invention are as follows:

[0014] (1) The wall-mounted support in this technical solution can control the lateral displacement and angle of the clamping block at the connection with the slide rail, which can drive the scaffold body to change with the change of the building cross section, so that the scaffold body can rise and fall more closely to the building surface, effectively solving the problem of large gaps between the scaffold body and the building, and making it safer.

[0015] (2) The installation ring, the first limiting groove, the second limiting groove and the limiting block can be set to control the lateral movement distance of the sliding column and the tilt angle of the clamping block relative to the horizontal plane separately, so that the wall-mounted support can be more precise in terms of angle adjustment and horizontal displacement control.

[0016] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0026] like Figures 1-6As shown, this invention discloses a high-rise variable cross-section attached lifting scaffold, comprising a scaffold body 1, a slide rail 2, and a wall-mounted support 3. The slide rail 2 includes parallel uprights 21 and several horizontal bars 22 between the uprights 21. The scaffold body 1 is fixed to the horizontal bars 22, and the slide rail 2 slides within the wall-mounted support 3. Specifically, the wall-mounted support 3 includes a U-shaped frame 310, with arc-shaped guide rails 315 arranged parallel between the two sides of the U-shaped frame 310. The two ends of the arc-shaped guide rails 315 are respectively fixed to the two sides of the U-shaped frame 310. Sliding columns 313 are slidably arranged on the arc-shaped guide rails 315, and the sliding columns 313 are provided with components that interact with the arc-shaped guide rails. The sliding column 313 has a matching through hole. Both ends of the sliding column 313 are provided with connecting shafts 312. The connecting shafts 312 are provided with rotating rings 317 and hydraulic rods 316. One end of the hydraulic rod 316 is hinged to the rotating ring 317 on the connecting shaft 312, and the other end of the hydraulic rod 316 is hinged to one side of the U-shaped frame 310. A through groove 311 is provided in the middle of one side of the U-shaped frame 310. A connecting plate 321 is provided in the through groove 311. One end of the connecting plate 321 is connected to the sliding column 313, and a clamping block 322 is provided on the other end of the connecting plate 321. The slide rail 2 is slidably connected to the clamping block 322.

[0027] The working principle of the above technical solution is as follows:

[0028] When the cross-section of the building is a vertical plane, there is no need to change the position and angle of the clamping block 322. Therefore, it is only necessary to install the slide rail 2 inside the clamping block 322. That is, under the action of lifting components such as electric hoists, the scaffold body 1 and the slide rail 2 will interact to rise or fall inside the clamping block 322.

[0029] When the scaffolding needs to be lifted from a vertical plane to a section with a certain angle of inclination (inward angle), the hydraulic rod 316 (a manual hydraulic rod 316 is acceptable) needs to be manually driven to move. The hydraulic rod 316... Figure 3 As shown in the installation direction, when the hydraulic rod 316 retracts, the sliding column 313 will climb along the arc-shaped guide rail 315. During the climbing process, it will not only drive the clamping block 322 to produce lateral displacement, but also drive the clamping block 322 to rotate upward at a certain angle. This angle only needs to match the angle of the building section. At this time, the lifting scaffold will rise along the building section at an angle. It is easy to understand that if the building tilt angle is an outward expansion angle, it is only necessary to control the hydraulic rod 316 to extend.

[0030] In one feasible embodiment, a mounting ring 318 is sleeved on the sliding column 313, and a connecting plate 321 is fixedly connected to the mounting ring 318. The mounting ring 318 is provided with a plurality of annularly distributed first limiting grooves 319, and the sliding column 313 is provided with a plurality of second limiting grooves 314 that match the first limiting grooves 319. At least one first limiting groove 319 is provided with a limiting block 320 for limiting the relative rotation of the sliding column 313 and the mounting ring 318. This configuration allows for individual control of the lateral movement distance of the sliding column 313 and the tilt angle of the clamping block 322 relative to the horizontal plane. This makes the control of the wall-mounted support 3 in terms of angle adjustment and horizontal displacement more precise. It is easy to understand that when the sliding column 313 climbs to a certain position along the arc-shaped guide rail 315 (the lateral displacement meets the requirements), it is only necessary to manually control the installation ring 318 to rotate on the sliding column 313. After the rotation angle of the clamping block 322 meets the requirements, the limiting block 320 can be inserted into the first limiting groove 319 and the second limiting groove 314 to fix their positions. This is because when the lifting scaffold is climbing a building with a variable cross-section, the lower wall-mounted support 3 needs to be continuously transferred to the upper part of the building for installation. When the entire lifting scaffold has not yet fully climbed to the cross-section of the building with the same tilt angle, the clamping block 322 in the upper wall-mounted support 3 needs to adjust its angle and lateral displacement to better connect with the sliding rail 2.

[0031] In one feasible embodiment, when the sliding column 313 is at the lowest point of the arc-shaped guide rail 315, the connecting plate 321 is in a horizontal state. That is, in this technical solution, the climbing direction of the sliding column 313 can be controlled, thereby controlling the rotation direction and the lateral displacement direction of the clamping block 322.

[0032] In one feasible embodiment, the U-shaped frame 310 has vertically arranged parallel screws 323 on its open side, with connecting blocks 327 at both ends of the screws 323. The U-shaped frame 310 has mounting grooves on both sides, which are slidably connected to the mounting grooves. The connecting blocks 327 can rotate vertically within the mounting grooves (the vertical height of the mounting grooves only needs to be relatively large). A limiting ring 325 is provided between the parallel screws 323, with the outer side of the limiting ring 325 slidably connected to the screws 323. Locking nuts are provided on both sides of the connecting screws 323. 324. After the sliding column 313 moves to the designated position, the position of the screw 323 and the position of the limiting ring 325 can be manually adjusted. The limiting ring 325 can then be sleeved on the connecting shaft 312. The position of the limiting ring 325 is then limited by the locking nut 324. Under the action of the limiting ring 325, the lateral movement of the sliding column 313 is restricted, thereby improving the connection and position limitation effect between the wall support 3 and the slide rail 2 (the sliding column 313 will not move on the arc-shaped guide rail 315 due to the hydraulic loss of the hydraulic rod 316).

[0033] In one feasible embodiment, a pre-tensioning spring 326 is provided in the mounting groove. One end of the pre-tensioning spring 326 is fixed in the groove, and the other end of the pre-tensioning spring 326 is fixed to the end of the connecting block 327. The setting of the pre-tensioning spring 326 and the setting of the warning spring can ensure that the limiting ring 325 is pulled tight to the connecting shaft 312 under normal conditions, avoiding the problem of falling off due to vibration or other reasons.

[0034] In one feasible embodiment, permanent magnets are provided at the bottom of the second limiting groove 314 and at both ends of the limiting block 320. The permanent magnets ensure that the limiting block 320 and the second limiting groove 314 are connected by magnetic adsorption, making the connection more stable and less likely to fall off.

[0035] In one feasible embodiment, an annular cover plate is provided on the open end of the U-shaped frame 310. The annular cover plate can further enhance the overall load-bearing performance of the wall-mounted support 3 structure and act as a reinforcing member.

[0036] In one feasible embodiment, a support column is provided on the side of the annular cover plate facing the clamping block 322. One end of the support column is unidirectionally rotatably connected to the annular cover plate, and the other end of the support column is located below the crossbar 22 of the slide rail 2. A U-shaped part is provided on this end, and a return spring is provided on the support column. When the slide rail 2 moves upward, the crossbar 22 contacts the support column, causing the support column to rotate to avoid it. After avoiding it, the interface rotates back to the initial position under the action of the return spring. That is, when an accident occurs and causes the slide rail 2 to fall downward, the support column can support the crossbar 22 to prevent it from falling. If the slide rail 2 needs to be lowered, the support column can be manually rotated to avoid it.

[0037] It should be noted that the existing wall-mounted lifting scaffold is an existing technology, and its various components and working principles will not be elaborated on here. The main improvement of the wall-mounted support 3 in this technical solution is to enable the traditional wall-mounted lifting leg, which can only go straight up and down, to achieve the effect of variable cross-section lifting.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
