[0002] The attached lifting scaffold is a new type of scaffold technology that has developed rapidly at the beginning of this century. It changes high-altitude operations into low-altitude operations and suspended operations into operations inside the scaffold body, with significant characteristics of low carbon, high-tech content, more economical and more convenient, etc.; the attached lifting scaffold, also known as a climbing scaffold, has an important impact on China's construction technology. The attached lifting scaffold is erected to a certain height and attached to the engineering structure, and can climb or descend layer by layer with the engineering structure relying on its own lifting device.

[0003] Chinese Patent CN213927415U discloses an attached lifting scaffold, which adopts the structural form of a first support frame between the first step and the second step of the lifting scaffold, and can effectively enhance the overall bearing capacity of the lifting scaffold.

A support bearing plate 305 is rotatably connected between the inner surfaces of the two transverse sides of the first groove 304. The top of the support bearing plate 305 has a circular limit groove 306 longitudinally near one end of the anti-falling lifting slide rail 4.

By setting one end of the support bearing plate 305 to extend into the second groove 402 to support the limit support block 404, the support and limit of the frame body 1 during normal use are realized. At the same time, through the cooperation of the spring 308, the first arc-shaped guiding insertion rod 309 and the second arc-shaped guiding insertion rod 310, a thrust is applied to the support bearing plate 305 to ensure the stability of its own position when supporting the limit support block 404, avoid displacement during the support and bearing process, and improve the safety of the frame body 1 during normal use; A limit pull rod 311 is provided between the support bearing plate 305 and the anti-falling lifting slide rail 4. Moving support plates 312 are provided at both transverse ends of the limit pull rod 311. One end of the moving support plate 312 is slidably connected to one transverse side of the support arm 302. A first telescopic device 313 is provided between the two transverse sides of the support arm 302 between the fixed connection plate 301 and the moving support plate 312. One end of the first telescopic device 313 is connected to the longitudinal side of the moving support plate 312. The first telescopic device 313 drives the limit pull rod 311 to move with the cooperation of the moving support plate 312 to pull the support bearing plate 305 out of the second groove 402, facilitating the smooth lifting of the lifting slide rail body 401;An arc-shaped reinforcing support plate 314 is provided between the bottom of the support arm 302 and the fixed connection plate 301. Limiting support plates 315 are provided on both the transverse sides of the arc-shaped reinforcing support plate 314 below the support arm 302. The limiting support plates 315 are arranged staggeredly up and down.

One end of the second telescopic device 318 extends into the arc-shaped reinforcing support plate 314 and is connected to the support prism 317. During the lifting and lowering process of the frame 1, in the case of the fracture of the steel wire rope 505, the second telescopic device 318 can drive the limiting locking block 316 to clamp the lifting slide rail body 401 in time under the cooperation of the limiting support plate 315 and the support prism 317, fix and limit it, and avoid the phenomenon of the frame falling.

[0041] As Figure 7 shown, the anti-falling connection seat 303 includes a U-shaped fixed connection seat 3031. Both ends of one longitudinal side of the U-shaped fixed connection seat 3031 are connected to the fixed connection plate 301, and a connecting rod 3032 is inserted and installed on the other side. A sliding limiting plate 3033 is provided at one end of the connecting rod 3032 located inside the U-shaped fixed connection seat 3031, and a steel wire rope connection ring 3034 is provided at the other end. The steel wire rope connection ring 3034 is used to connect with the steel wire rope. The two transverse side surfaces of the sliding limiting plate 3033 are respectively slidably connected with the two transverse inner surfaces of the U-shaped fixed connection seat 3031. Pressure sensors 3035 are provided on the inner surface of one longitudinal side of the U-shaped fixed connection seat 3031 on both sides of the connecting rod 3032. During the lifting and lowering process of the frame 1, the steel wire rope 505 will apply a certain pulling force to the steel wire rope connection ring 3034, causing the sliding limiting plate 3033 to slide along the inner side of the U-shaped fixed connection seat 3031 and press against the pressure sensor 3035. Furthermore, the magnitude of the pulling force borne by the steel wire rope connection ring 3034 can be monitored in real time through the pressure sensor 3035. After the steel wire rope 505 breaks and the data monitored by the pressure sensor 3035 changes greatly, it will be transmitted to the control device 7 immediately, and then the control device 7 controls the first telescopic device 313 and the second telescopic device 318 to work to fix and limit the lifting slide rail body 401 and avoid the phenomenon of its falling.

[0042] As Figure 8As shown in the figure, the anti-falling lifting slide rail 4 includes a lifting slide rail body 401. One longitudinal end of the lifting slide rail body 401 is slidably connected to the support arm 302, and the other end is connected to the support vertical rod 103. There are anti-disengagement chutes 403 at the sliding connection positions of the two lateral sides of the lifting slide rail body 401 with the support arm 302. A number of limit support blocks 404 are equidistantly arranged from top to bottom inside the second groove 402. A guide block 405 is arranged at the top of the limit support block 404, and a circular limit protrusion 406 matching the circular limit groove 306 is arranged at the bottom, which is used to realize the vertical lifting of the frame body 1 on the anti-falling wall-mounted support 3. The anti-disengagement chute 403 arranged therein can make the sliding connection between the lifting slide rail body 401 and the support arm 302 more stable, avoiding the lifting slide rail body 401 from disengaging from the support arm 302. At the same time, the second groove 402 and the limit support blocks 404 arranged can facilitate the support plate 305 to support and lift the lifting slide rail body 401, ensuring the stability and firmness of the frame body 1 during normal use. In addition, the guide block 405 arranged can facilitate the support plate 305 to leave the second groove 402 more smoothly during the rising process of the frame body 1, avoiding jamming phenomena and improving the smoothness of the rising of the frame body 1. Furthermore, the circular limit protrusion 406 arranged can be inserted and matched with the circular limit groove 306. During the normal use of the frame body 1, it can avoid the frame body 1 from being prone to displacement phenomena, further improving the stability of the frame body 1 during use. The insertion end of the circular limit protrusion 406 is also chamfered to be more conveniently inserted and matched with the circular limit groove 306.

[0043] As Figures 2 to 3 As shown in the figure, the lifting assembly 5 includes a lower truss 501. An upper truss 502 is arranged above the lower truss 501. Support connecting plates 503 are arranged at the two longitudinal ends of the bottoms of the lower truss 501 and the upper truss 502. One side of the support connecting plate 503 is connected to the support vertical rod 103. Electric hoists 504 are arranged at the bottoms of the upper trusses 502. The electric hoists 504 are connected with steel wire ropes 505. A second hollow opening 506 is arranged at the position of the lower truss 501 corresponding to the electric hoists 504. At least two guide wheels 507 are arranged between one end of the bottom of the lower truss 501 close to the anti-falling wall-mounted support 3 and the second hollow opening 506. One end of the steel wire rope 505 passes through the second hollow opening 506 and the guide wheels 507 in sequence and is connected to the steel wire rope connection ring 3034. The structure formed by the cooperation of the lower truss 501, the upper truss 502 and the support connecting plates 503 ensures the stability and firmness of the lifting point position of the electric hoist 504. The arrangement of the guide wheels 507 can prevent the frame body 1 or the anti-falling wall-mounted support 3, etc. from interfering with the movement of the steel wire rope 505. By driving one end of the steel wire rope 505 to rise and fall through the electric hoist 504, the overall lifting of the frame body 1 is realized.

[0044] As Figure 9As shown in the figure, the anti-tilting component 6 includes a first limit support column 601 and a second limit support column 602. The first limit support column 601 is arranged at the top of the building layer wall 2, and the second limit support column 602 is arranged at the top of the roof slab 102. Limit connection plates 603 are arranged on both the lateral sides of the first limit support column 601 and the second limit support column 602. Arc-shaped grooves matching the outer contours of the first limit support column 601 and the second limit support column 602 are respectively arranged at both ends of the inner side of the limit connection plate 603. Limit pressure plates 604 are arranged at the positions corresponding to the tops of the limit connection plates 603 on the first limit support column 601 and the second limit support column 602. Fixed adjustment bolts 605 are arranged to connect between both ends of the limit connection plate 603. The overall disassembly and assembly are convenient. When the frame 1 is in normal use, a connection relationship is generated between the frame 1 and the building layer wall 2, improving the stability of the frame 1 during use and avoiding the phenomenon of the frame 1 tipping over. In addition, the arranged limit pressure plates 604 can prevent the limit connection plates 603 from separating from the first limit support column 601 and the second limit support column 602, ensuring the stability of the overall use effect of the anti-tilting component 6.

[0045] A protective folding plate is rotatably connected to one end of the anti-slip foot plank 104 longitudinally close to the building layer wall 2, preventing foreign objects generated during construction from falling between the frame 1 and the building layer wall 2 and avoiding the phenomenon of falling objects from height injuring people, further improving the safety of use; a dust-proof net is arranged between the support vertical poles 103 on the outer side of the inclined strut 107, reducing the diffusion of dust generated during construction and improving the environmental protection of use; the first telescopic device 313, the second telescopic device 318, the pressure sensor 3035 and the electric hoist 504 are all electrically connected to the control device 7, facilitating the control device 7 to control the working states of the first telescopic device 313, the second telescopic device 318 and the electric hoist 504 and receiving the data actually transmitted by the pressure sensor 3035. Among them, the first telescopic device 313 and the second telescopic device 318 are one of a servo electric cylinder, a cylinder, a hydraulic cylinder, a push rod motor or an electric telescopic rod.

[0046] Working principle: During the normal construction use of the frame body, through the cooperation of the set supporting vertical plates, springs, first arc-shaped guiding and inserting rods, and second arc-shaped guiding and inserting rods, a certain thrust is applied to the supporting bearing plate, so that the supporting bearing plate stably extends into the second groove to support the limiting support block, thereby realizing the support and bearing of the overall frame body; during the normal construction use of the frame body, through the protective support groove structure arranged on the lifting slide rail body, the situation that the lifting slide rail body is prone to break away from the support arm can be avoided. In addition, the circumferential limiting groove arranged at the top of the supporting bearing plate and the circumferential limiting protrusion arranged at the bottom of the limiting support block are inserted and connected in cooperation to constrain the stable invariance of the relative distance between the supporting bearing plate and the lifting slide rail body, realizing the multiple limiting effect on the anti-falling lifting slide rail as a whole and avoiding the phenomenon of horizontal displacement of the frame body during normal use; during the normal construction use of the frame body, the limiting connecting plate in the anti-tilting component can stably and firmly ensure the stable invariance of the relative distance between the first limiting support column and the second limiting support column respectively arranged on the frame body and the building layer wall body. At the same time, the set limiting pressure plate can limit the limiting connecting plate to prevent it from detaching from the first limiting support column and the second limiting support column, thereby realizing the avoidance of the phenomenon that the frame body is prone to tipping during use. At the same time, the disassembly and assembly are simple and convenient to operate; through the above three methods, the stability of the frame body during normal construction use is realized, avoiding the phenomena of falling or tipping that are prone to occur when the frame body is in normal construction use, thereby improving the safety of use;

[0047] During the rising process of the frame, the electric hoist is controlled to pull the wire rope to rise. The scaffolding board and the lower truss are respectively provided with a first hollow opening and a second hollow opening for the electric hoist and the wire rope to pass through. The guide wheel arranged at the bottom of the lower truss can avoid the interference of the frame or the anti-fall wall support while changing the direction of the wire rope. When the electric hoist lifts one end of the wire rope, the circular limiting groove on the support bearing plate and the circular limiting protrusion at the bottom of the limiting support block will separate, and the frame as a whole will rise with the anti-fall lifting rail, and the supporting bearing plate will be guided by the guide block at the top of the lower limiting support block, temporarily leave the second groove, pass the limiting support block at the bottom of the guide block, and enter the second groove again until the frame rises to the specified position, and then the electric hoist and the wire rope cooperate to continue to lead The movable frame body drops slightly, so that one end of the supporting load-bearing plate enters the second groove to support and bear the limit support block above it, and at the same time the circular limit protrusion is plugged into and matched with the circular limit groove; during the rising process of the frame body, the wire rope will transmit the tension it bears to the pressure sensor for real-time monitoring through the wire rope connecting ring, the connecting rod, the sliding limit plate and the U-shaped fixed connecting seat. When the wire rope breaks, the pressure sensor detects that the tension borne by the wire rope has a large change, and will immediately send a signal to the control device, and then the control device controls the second telescopic device to work. The second telescopic device can timely drive the limit locking block to clamp the lifting slide rail body with the cooperation of the limit support plate and the supporting prism, fix it and limit it, and prevent the frame from falling.

[0048] During the descent of the frame, it is necessary to first control the first telescopic device to drive the limit pull rod to move with the cooperation of the moving support plate. Through the limit pull rod, the support bearing plate is pushed out of the second groove. Then, the electric hoist drives one end of the steel wire rope to descend. After descending to the designated position, the first telescopic device drives the limit pull rod away from the support bearing plate with the cooperation of the moving support plate. At the same time, the spring, with the cooperation of the first arc-shaped guiding and inserting rod and the second arc-shaped guiding and inserting rod, pushes the support bearing plate into the second groove. Then, through the cooperation of the electric hoist and the steel wire rope, the frame is further driven to descend slightly until the circular limit protrusion is inserted and matched with the circular limit groove, and the support bearing plate can support the limit support block. Similarly, during the descent of the frame, the steel wire rope transmits the tensile force it bears to the pressure sensor for real-time monitoring through the cooperation of the steel wire rope connection ring, the connecting rod, the sliding limit plate, and the U-shaped fixed connection seat. When the steel wire rope breaks, the pressure sensor detects a large change in the tensile force borne by the steel wire rope and sends a signal to the control device immediately. Different from the ascending process of the frame, the control device will control the first telescopic device and the second telescopic device to work simultaneously. The first telescopic device drives the limit pull rod away from the support bearing plate with the cooperation of the moving support plate, so that the spring, with the cooperation of the first arc-shaped guiding and inserting rod and the second arc-shaped guiding and inserting rod, pushes the support bearing plate into the second groove. The second telescopic device drives the limit locking block to clamp the lifting slide rail body with the cooperation of the limit support plate and the support prism to fix and limit it, preventing the frame from falling.
