Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, specifically to an integrated jacking device for scaffolding inside a foundation pit. Background Technology

[0002] With the proliferation of infrastructure projects, scaffolding plays a crucial role in the construction of various high-rise buildings, primarily serving the following functions: 1. As a tool: Construction of building exterior walls and facades requires working on external surfaces, and the scaffolding, with its planks, provides a platform for workers. 2. Ensuring safety: Simple supports and planks are insufficient for fall prevention; horizontal bars and safety nets must be added to create guardrails and fall buffers, ensuring worker safety and preventing injuries from falling objects. 3. Environmental friendliness: Dense mesh netting on the scaffolding effectively reduces wind force and prevents construction dust from being blown into the environment, minimizing dust pollution during construction. It also effectively absorbs and reduces construction noise, preventing disturbance to residents.

[0003] However, scaffolding construction often requires workers to use steel pipes to build it layer by layer from the ground. As the construction height increases, the workers are at a higher altitude, making material transportation inconvenient, construction efficiency low, and the safety of workers working at height difficult to guarantee. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: A scaffolding lifting device for a foundation pit, comprising a support mechanism and a bracket disposed at the bottom of the support mechanism. The top of the bracket is fixedly connected to the bottom of the support mechanism. A cylinder is fixedly connected to the bottom of the bracket, and a pad is rotatably connected to the bottom of the cylinder. A lifting mechanism is symmetrically arranged at the top end of the bracket away from the support mechanism, and the lifting mechanism and the support mechanism are staggered. The bottom of the lifting mechanism is fixedly connected to the top of the bracket. A shielding mechanism is used to block falling debris. The top of the shielding mechanism is sleeved with the outer surface of the support mechanism, and the top end of the shielding mechanism away from the support mechanism is sleeved with the outer surface of the lifting mechanism. A protective mechanism is used to maintain the scaffolding's fixation. The bottom of the protective mechanism is fixedly connected to the top of the support mechanism.

[0005] The protective mechanism includes an irregularly shaped frame. Guide components are evenly distributed on the outer surface of the frame, and the outer surface of the guide components is fixedly connected to the outer surface of the frame. A slot is provided at the top of the frame at the end furthest from the guide components. Two irregularly shaped frames are symmetrically arranged. An adjusting component is fixedly connected to the end of the frame closest to the guide components, and the end of the adjusting component furthest from the frame is fixedly connected to the guide components. The guide components hold the vertical poles of the scaffolding in place, allowing them to be lifted and moved upwards within the guide components. This serves to fix the movement of the scaffolding and limits its direction of movement to prevent excessive height, instability, and potential collapse. The adjusting component controls the distance between the two vertical poles, ensuring vertical movement during movement and enhancing the stability of the device.

[0006] Preferably, the protective mechanism further includes a rotating column, the bottom of which is fixedly connected to the top of the support mechanism, and the bottom of the top irregular frame of the rotating column is rotatably connected.

[0007] Preferably, the support mechanism includes a first telescopic column, the bottom of which is fixedly connected to the top of the bracket. A first slider is slidably connected to the outer surface of the first telescopic column at the end away from the bracket. A first baffle is rotatably connected to the bottom of the first slider. A first hook is rotatably connected to the bottom of the first baffle at the end away from the first slider. The outer surface of the first hook is sleeved with the top of the shielding mechanism. First connecting rods are symmetrically arranged on the outer surface of the first baffle. The outer wall of the first connecting rod is rotatably connected to the outer surface of the first baffle. A first support plate is rotatably connected to the end of the first connecting rod away from the first baffle. The inner wall of the first support plate is rotatably connected to the top of the first telescopic column. An infrared receiving module is provided on the outer wall of the first telescopic column at the end near the bracket.

[0008] Preferably, the shielding mechanism includes a buffer sleeve, a protective net fixedly connected to the top of the buffer sleeve, a U-shaped plate fixedly connected to the outer surface of the protective net, hanging rings evenly arranged on the top of the U-shaped plate, the bottom of the hanging rings fixedly connected to the top of the U-shaped plate, the hanging rings being sleeved with a first hook, and opening and closing plates evenly arranged on the outer surface of the U-shaped plate, the outer wall of the opening and closing plates being rotatably connected to the inner wall of the U-shaped plate. This can prevent the vertical pole from falling and directly hitting the worker, and increase the reaction time in the event of danger, helping the worker to quickly leave the danger zone and enhancing safety.

[0009] Preferably, the guide assembly includes a telescopic rod, the outer wall of which is fixedly connected to the outer wall of the irregular frame. A fixed seat is fixedly connected to the end of the telescopic rod away from the irregular frame. A first retaining ring and a second retaining ring are respectively provided on the inner wall of the fixed seat. The outer wall of the first retaining ring is rotatably connected to the inner wall of the fixed seat, and the outer wall of the second retaining ring is rotatably connected to the inner wall of the fixed seat. The end of the first retaining ring near the telescopic rod is rotatably connected to the end of the second retaining ring near the telescopic rod. An elastic band is fixedly connected to the inner wall of the first retaining ring, and the end of the elastic band away from the first retaining ring is fixedly connected to the end of the second retaining ring. This maintains the stability and directional consistency of the scaffold during movement, preventing swaying of the scaffold due to increased center of gravity and airflow during movement, which could cause parts to loosen.

[0010] Preferably, the adjusting assembly includes a rotating shaft, the outer wall of which is fixedly connected to the outer wall of the irregular frame. A first rotating plate is rotatably connected to the end of the rotating shaft away from the irregular frame. The end of the first rotating plate away from the rotating shaft is fixedly connected to the outer wall of the telescopic rod. A slide rail is symmetrically provided at the end of the first rotating plate away from the telescopic rod. A limit rod is provided inside the slide rail. A second rotating plate is fixedly connected to the end of the limit rod away from the first rotating plate. The end of the second rotating plate away from the limit rod is rotatably connected to the outer wall of the irregular frame. This is used to assist the guiding assembly in maintaining equal distance between the vertical rods, reducing relative friction and swaying between the rods, and protecting the stability of the scaffold connection.

[0011] Preferably, the lifting mechanism includes a second telescopic column, the bottom of which is fixedly connected to the top of the bracket. A second slider is slidably connected to the outer surface of the second telescopic column away from the bracket. A second baffle is rotatably connected to the bottom of the second slider. A second hook is rotatably connected to the bottom of the second baffle away from the second slider. The outer surface of the second hook is sleeved with the top of the shielding mechanism. Second connecting rods are symmetrically arranged on the outer surface of the second baffle. The outer wall of the second connecting rod is rotatably connected to the outer surface of the second baffle. A second support plate is rotatably connected to the end of the second connecting rod away from the second baffle. The inner wall of the second support plate is rotatably connected to the top of the second telescopic column. An infrared generator is provided on the outer wall of the second telescopic column near the bracket. The movement of the first and second baffles drives the movement of the supporting scaffold from multiple angles, preventing uneven stress on the scaffold, which could lead to loosening at the connection points or deformation of the scaffold, causing safety hazards. At the same time, with the cooperation of the protective mechanism, the scaffold is stably supported, facilitating better installation and dismantling by workers and improving work efficiency.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. This invention, through the setting of a protective mechanism, uses a guide component to lock the vertical poles of the scaffolding, and then lifts them, causing the vertical poles to move upwards within the guide component. This serves to fix the movement of the scaffolding and limit its direction of movement to a certain extent, preventing the scaffolding from becoming too tall, unstable, and prone to tipping over or collapsing. The adjusting component controls the distance between two vertical poles, ensuring that the vertical poles move vertically during movement and enhancing the stability of the device. After moving to the appropriate position, the irregular frame rotates, placing the locking slot horizontally at the bottom of the horizontal pole, locking the erected scaffolding and preventing the scaffolding from falling due to instability in the lifting mechanism, thus enhancing the safety of the device.

[0014] 2. This invention, through the setting of a guiding component, initially opens the first and second retaining rings, and the telescopic rod extends to drive the elastic band close to the vertical rod. After the vertical rod contacts the elastic band, the first and second retaining rings move closer to each other under the action of elasticity. The contact surfaces of the first and second retaining rings are provided with magnetic plates, so that the vertical rod is locked in the loop of the first and second retaining rings. As the scaffolding rises, the vertical rod moves within the loop, maintaining the stability and directional consistency of the scaffolding during the movement, and avoiding swaying of the scaffolding due to the increase of the center of gravity and air flow during the movement, which could cause parts to loosen.

[0015] 3. This invention, by setting an adjustment component, allows the first rotating plate to rotate after the guide component encircles the vertical rod. This causes the limiting rod to slide along the track into the second rotating plate and be locked in place, creating a stable support between the two irregularly shaped frames. After the lifting is completed, the guide component is retracted, and the rotating shaft drives the limiting rod away from the second rotating plate, allowing the irregularly shaped frame to rotate and lock the scaffolding. This assists the guide component in maintaining equal distances between the vertical rods, reducing relative friction and swaying between the rods, and protecting the stability of the scaffolding connections.

[0016] 4. This invention incorporates a shielding mechanism. During scaffolding movement, loose connections can easily cause vertical poles to slip, posing a significant threat to workers below. Therefore, before construction, workers hang a U-shaped shield at the bottom of the first and second hooks, and install a protective net in the middle of the shield. The net has moderate elasticity, acting as a buffer in case of a falling vertical pole. The vertical pole is then guided into the buffer sleeve. Workers typically install this below the U-shaped shield, thus preventing the falling pole from directly hitting them and increasing reaction time in case of danger, helping workers quickly escape the danger zone and enhancing safety.

[0017] 5. This invention, through the setting of a support mechanism, initially adjusts the height of the bracket to keep its top level. At this time, the infrared generator on the second telescopic column emits infrared rays, which are received by the infrared receiving module on the first telescopic column. When the signal is successfully received, it indicates that the first and second telescopic columns are in a horizontal state. When lifting is required, the first and second baffles rotate to the horizontal, simultaneously driving the first and second support plates to lock the crossbars of the scaffold in the recesses. Under the action of the first and second telescopic columns, the four sets of first support plates and the four sets of second support plates simultaneously lift the crossbars upward. The first and second hooks hook the shielding mechanism and move simultaneously with the first and second telescopic columns. Through the movement of the first and second baffles, the movement of the supported scaffold is driven from multiple angles, avoiding uneven stress on the scaffold, which can easily lead to loosening at the joints or deformation of the scaffold, causing safety hazards. At the same time, with the cooperation of the protective mechanism, the scaffold is stably supported, making it easier for workers to install and dismantle, and improving work efficiency.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] Example 1, using Figures 1-5 The following is a description of an overall jacking device for scaffolding in a foundation pit according to one embodiment of the present invention.

[0030] like Figures 1-5 As shown, the present invention discloses an overall scaffolding lifting device in a foundation pit, comprising a support mechanism 4, a bracket 3 disposed at the bottom of the support mechanism 4, the top of the bracket 3 being fixedly connected to the bottom of the support mechanism 4, a cylinder 2 being fixedly connected to the bottom of the bracket 3, a pad 1 being rotatably connected to the bottom of the cylinder 2, a lifting mechanism 7 being symmetrically arranged at the top of the bracket 3 away from the support mechanism 4, the lifting mechanism 7 being staggered with the support mechanism 4, and the bottom of the lifting mechanism 7 being fixedly connected to the top of the bracket 3; a shielding mechanism 5, which is used to block debris falling from above, the top of the shielding mechanism 5 being sleeved with the outer surface of the support mechanism 4, and the top of the shielding mechanism 5 being sleeved with the outer surface of the lifting mechanism 7; and a protective mechanism 6, which is used to keep the scaffolding fixed, the bottom of the protective mechanism 6 being fixedly connected to the top of the support mechanism 4.

[0031] During operation, workers adjust the height of cylinder 2 to ensure that bracket 3 is at the same horizontal level, preventing uneven ground in the pit from causing the device to tilt. Scaffolding is then installed on bracket 3. After each layer is erected, support mechanism 4 drives protective mechanism 6 to secure the vertical poles of the scaffolding. Subsequently, lifting mechanism 7 and support mechanism 4 simultaneously lift the scaffolding. Workers then continue to build the bottom layer of the scaffolding, raising it layer by layer as it is completed, gradually building the scaffolding to the appropriate height from the bottom. Protective mechanism 6 and shielding mechanism 5 provide safety protection for workers, preventing loosening and collapse that could injure workers, or other debris falling from the site and causing injury or death.

[0032] The protective mechanism 6 includes a shaped frame 602, on which guide components 603 are evenly distributed on the outer surface. The outer surface of the guide components 603 is fixedly connected to the outer surface of the shaped frame 602. A slot 605 is opened on the top of the end of the shaped frame 602 away from the guide components 603. Two shaped frames 602 are symmetrically arranged. An adjustment component 604 is fixedly connected to the end of the shaped frame 602 near the guide components 603. The end of the adjustment component 604 away from the shaped frame 602 is fixedly connected to the guide components 603. The protective mechanism 6 also includes a rotating column 601. The bottom of the rotating column 601 is fixedly connected to the top of the support mechanism 4. The top of the rotating column 601 is rotatably connected to the bottom of the shaped frame 602.

[0033] During operation, the guide assembly 603 secures the vertical poles of the scaffolding, which are then lifted. This allows the vertical poles to move upwards within the guide assembly 603, fixing the movement of the scaffolding and limiting its direction of movement. This prevents the scaffolding from becoming too tall, unstable, or prone to tipping and collapse. The adjusting assembly 604 controls the distance between the two vertical poles, ensuring vertical movement and enhancing the stability of the device. Once the scaffolding is in the correct position, the irregular frame 602 rotates, placing the locking slot 605 across the bottom of the horizontal pole to secure the erected scaffolding. This prevents the lifting mechanism 7 from becoming unstable and causing the scaffolding to fall, thus enhancing the safety of the device.

[0034] The support mechanism 4 includes a first telescopic column 401, the bottom of which is fixedly connected to the top of the bracket 3. A first slider 402 is slidably connected to the outer surface of the first telescopic column 401 away from the bracket 3. A first baffle 403 is rotatably connected to the bottom of the first slider 402. A first hook 404 is rotatably connected to the bottom of the first baffle 403 away from the first slider 402. The outer surface of the first hook 404 is sleeved with the top of the shielding mechanism 5. A first connecting rod 405 is symmetrically arranged on the outer surface of the first baffle 403. The outer wall of the first connecting rod 405 is rotatably connected to the outer surface of the first baffle 403. A first support plate 406 is rotatably connected to the end of the first connecting rod 405 away from the first baffle 403. The inner wall of the first support plate 406 is rotatably connected to the top of the first telescopic column 401. An infrared receiving module 407 is arranged on the outer wall of the first telescopic column 401 near the bracket 3.

[0035] The lifting mechanism 7 includes a second telescopic column 701. The bottom of the second telescopic column 701 is fixedly connected to the top of the bracket 3. A second slider 702 is slidably connected to the outer surface of the second telescopic column 701 away from the bracket 3. A second baffle 703 is rotatably connected to the bottom of the second slider 702. A second hook 704 is rotatably connected to the bottom of the second baffle 703 away from the second slider 702. The outer surface of the second hook 704 is sleeved with the top of the blocking mechanism 5. A second connecting rod 705 is symmetrically arranged on the outer surface of the second baffle 703. The outer wall of the second connecting rod 705 is rotatably connected to the outer surface of the second baffle 703. A second support plate 706 is rotatably connected to the end of the second connecting rod 705 away from the second baffle 703. The inner wall of the second support plate 706 is rotatably connected to the top of the second telescopic column 701. An infrared generator 707 is arranged on the outer wall of the second telescopic column 701 near the bracket 3.

[0036] Initially, the height of bracket 3 is adjusted to keep its top level. At this time, the infrared generator 707 on the second telescopic column 701 emits infrared rays, which are received by the infrared receiver module 407 on the first telescopic column 401. When the signal is successfully received, it indicates that the first telescopic column 401 and the second telescopic column 701 are in a horizontal state. When it is necessary to lift, the first baffle 403 and the second baffle 703 rotate to the horizontal, and at the same time, the first support plate 406 and the second support plate 701 lock the crossbar of the scaffolding into the recess. Under the action of the first telescopic column 401 and the second telescopic column 701, the fourth group of... The first support plate 406 and the four sets of second support plates 706 simultaneously lift the crossbar upwards. The first hook 404 and the second hook 704 hook the shielding mechanism 5 and move simultaneously with the first telescopic column 401 and the second telescopic column 701. The movement of the first baffle 403 and the second baffle 703 drives the movement of the supporting scaffold from multiple angles, avoiding uneven stress on the scaffold, which may cause loosening at the connection or deformation of the scaffold, resulting in safety hazards. At the same time, with the cooperation of the protective mechanism 6, the scaffold is stably supported, making it easier for workers to install and dismantle, and improving work efficiency.

[0037] The specific workflow is as follows:

[0038] During operation, workers adjust the height of cylinder 2 to ensure that bracket 3 is at the same horizontal level, preventing uneven ground in the pit from causing the device to tilt. Scaffolding is then installed on bracket 3. After each layer is erected, support mechanism 4 drives protective mechanism 6 to secure the vertical poles of the scaffolding. Subsequently, lifting mechanism 7 and support mechanism 4 simultaneously lift the scaffolding. Workers then continue to build the bottom layer of the scaffolding, raising it layer by layer as it is completed, gradually building the scaffolding to the appropriate height from the bottom. Protective mechanism 6 and shielding mechanism 5 provide safety protection for workers, preventing loosening and collapse that could injure workers, or other debris falling from the site and causing injury or death.

[0039] Example 2, using Figures 1-9 The following is a description of an overall jacking device for scaffolding in a foundation pit according to one embodiment of the present invention.

[0040] like Figures 1-9 As shown, the overall jacking device for scaffolding in a foundation pit according to the present invention, based on Embodiment 1, includes a shielding mechanism 5 comprising a buffer sleeve 501, a protective net 502 fixedly connected to the top of the buffer sleeve 501, a U-shaped plate 504 fixedly connected to the outer surface of the protective net 502, hanging rings 503 evenly arranged on the top of the U-shaped plate 504, the bottom of the hanging rings 503 being fixedly connected to the top of the U-shaped plate 504, the hanging rings 503 being sleeved with the first hook 404, and opening and closing plates 505 evenly arranged on the outer surface of the U-shaped plate 504, the outer wall of the opening and closing plates 505 being rotatably connected to the inner wall of the U-shaped plate 504;

[0041] During the movement of scaffolding, loose connections can easily cause vertical poles to slip and fall, posing a significant threat to workers below. Therefore, before construction, workers hang the U-shaped plate 504 at the bottom of the first hook 404 and the second hook 704, and install a safety net 502 in the middle of the U-shaped plate 504. The safety net 502 has moderate elasticity and acts as a buffer when the vertical pole falls. Then, the vertical pole is guided into the buffer sleeve 501. Workers usually install it below the U-shaped plate 504, which can prevent the vertical pole from falling and hitting the workers directly, and increase reaction time in case of danger, helping workers to quickly leave the danger zone and enhancing safety.

[0042] The guide assembly 603 includes a telescopic rod 6031. The outer wall of the telescopic rod 6031 is fixedly connected to the outer wall of the irregular frame 602. A fixed seat 6032 is fixedly connected to the end of the telescopic rod 6031 away from the irregular frame 602. A first retaining ring 6033 and a second retaining ring 6034 are respectively provided on the inner wall of the fixed seat 6032. The outer wall of the first retaining ring 6033 is rotatably connected to the inner wall of the fixed seat 6032. The outer wall of the second retaining ring 6034 is rotatably connected to the inner wall of the fixed seat 6032. The end of the first retaining ring 6033 near the telescopic rod 6031 is rotatably connected to the end of the second retaining ring 6034 near the telescopic rod 6031. An elastic band 6035 is fixedly connected to the inner wall of the first retaining ring 6033. The end of the elastic band 6035 away from the first retaining ring 6033 is fixedly connected to the end of the second retaining ring 6034.

[0043] Initially, the first retaining ring 6033 and the second retaining ring 6034 open, and the telescopic rod 6031 extends, causing the elastic band 6035 to approach the vertical rod. After the vertical rod contacts the elastic band 6035, the elastic force causes the first retaining ring 6033 and the second retaining ring 6034 to move closer together. Magnetic plates are provided on the contact surfaces of the first retaining ring 6033 and the second retaining ring 6034, causing the vertical rod to be locked within the loop of the first retaining ring 6033 and the second retaining ring 6034. As the scaffolding rises, the vertical rod moves within this loop, maintaining the stability and directional consistency of the scaffolding during movement and preventing swaying of the scaffolding due to increased center of gravity and airflow during movement. This causes parts to loosen. After moving one layer, the telescopic rod 6031 retracts, causing the first retaining ring 6033 and the second retaining ring 6034 to move away from the vertical rod. The first telescopic column 401 and the second telescopic column 701 continue to rise, making the slot 605 of the irregular frame 602 level with the horizontal bar. The irregular frame 602 rotates 90 degrees to lock the horizontal bar in the slot 605. At this time, the workers continue to build. After the building is completed, the first telescopic column 401 and the second telescopic column 701 work together to lift the scaffolding a certain distance and move the horizontal bar away from the irregular frame 602. Then the irregular frame 602 rotates back to its original position, and the telescopic rod 6031 extends to encircle the vertical bar again and lift it.

[0044] The adjustment assembly 604 includes a rotating shaft 6041. The outer wall of the rotating shaft 6041 is fixedly connected to the outer wall of the irregular frame 602. A first rotating plate 6042 is rotatably connected to the end of the rotating shaft 6041 away from the irregular frame 602. The end of the first rotating plate 6042 away from the rotating shaft 6041 is fixedly connected to the outer wall of the telescopic rod 6031. A slide rail 6045 is symmetrically provided at the end of the first rotating plate 6042 away from the telescopic rod 6031. A limit rod 6043 is provided inside the slide rail 6045. A second rotating plate 6044 is fixedly connected to the end of the limit rod 6043 away from the first rotating plate 6042. The end of the second rotating plate 6044 away from the limit rod 6043 is rotatably connected to the outer wall of the irregular frame 602.

[0045] After the guide assembly 603 encircles the vertical pole, the rotating shaft 6041 drives the first rotating plate 6042 to rotate, causing the limiting rod 6043 to enter the second rotating plate 6044 along the slide rail 6045 and lock in place, thus forming a stable support between the two irregular frames 602. After the lifting is completed, the guide assembly 603 is retracted, and the rotating shaft 6041 drives the limiting rod 6043 away from the second rotating plate 6044, allowing the irregular frame 602 to rotate and lock the scaffolding. This assists the guide assembly 603 in maintaining equal distance between the vertical poles, reducing relative friction and swaying between the poles, and protecting the stability of the scaffolding connection.

[0046] The specific workflow is as follows:

[0047] During work, before construction, workers hang the U-shaped scaffolding 504 at the bottom of the first hook 404 and the second hook 704. A safety net 502 is installed in the middle of the U-shaped scaffolding 504. The safety net 502 has moderate elasticity and acts as a buffer if the vertical pole falls. The vertical pole is then guided into the buffer sleeve 501, which workers usually install below the U-shaped scaffolding 504. When moving the scaffolding, the first locking ring 6033 and the second locking ring 6034 open, and the telescopic pole 6031 extends, causing the elastic band 6035 to approach the vertical pole. The vertical pole then contacts the elastic band 6035. After 35 seconds, under the action of elasticity, the first retaining ring 6033 and the second retaining ring 6034 move closer to each other. Magnetic plates are provided on the contact surfaces of the first retaining ring 6033 and the second retaining ring 6034, causing the vertical rod to be locked within the loops of the first retaining ring 6033 and the second retaining ring 6034. As the scaffold rises, the vertical rod moves within these loops, maintaining the stability and directional consistency of the scaffold during movement. This prevents the scaffold from swaying due to increased center of gravity and airflow during movement, which could cause parts to loosen. After moving one layer, the telescopic rod 6031 retracts. As the first retaining ring 6033 and the second retaining ring 6034 move away from the vertical bar, the first telescopic column 401 and the second telescopic column 701 continue to rise, making the slot 605 of the irregular frame 602 level with the horizontal bar. The irregular frame 602 rotates 90 degrees to lock the horizontal bar into the slot 605. At this time, the workers continue to assemble. After the assembly is completed, the first telescopic column 401 and the second telescopic column 701 work together to lift the scaffolding a certain distance, moving the horizontal bar away from the irregular frame 602. Then the irregular frame 602 rotates back to its original position, and the telescopic rod 6031 extends to encircle the vertical bar again. The lifting process is carried out. After the guide assembly 603 encircles the vertical bar, the rotating shaft 6041 drives the first rotating plate 6042 to rotate, causing the limiting rod 6043 to enter the second rotating plate 6044 along the slide rail 6045 and be locked in place, so that a stable support is formed between the two irregular frames 602. After the lifting is completed, the guide assembly 603 is retracted, and the rotating shaft 6041 drives the limiting rod 6043 away from the second rotating plate 6044, so that the irregular frame 602 can rotate to lock the scaffolding, which is used to assist the guide assembly 603 in maintaining an equal distance between the vertical bars.
