[0076] In addition, due to different working environments, the load, lifting height and moving speed threshold value of the lower rollers on the working platform can be manually set, and the threshold value segment can also be set, the movable intelligent scaffold is limited and controlled by manually inputting the threshold value of the working parameters of the movable intelligent scaffold, and the safety in use is increased; after adjusting the horizontal range of the working platform of the movable intelligent scaffold, the slope display instrument is used to detect the inclination of the working platform in real time; when the level of the working platform is 0-5°, the working performance is the maximum limit of 80% of the working performance of the movable intelligent scaffold; when the level of the working platform is 5°-10°, the working performance is the maximum limit of 40% of the working performance of the movable intelligent scaffold; when it exceeds 10°, all operations are automatically stopped.

[0077] Meanwhile, the four fixing rods 11 can be hydraulic rods connected with a horizontal detection instrument, and the horizontal state of the working platform obtained by the horizontal detection instrument is used to adjust the hydraulic rods mounted on the fixing rods, so that the working platform can keep a horizontal state in real time.

[0078] The feedback module is configured to feed back the values of the state factors of the platform 7 in use to the control end, the anti-collision display and the platform height display instrument 9.

[0079] The indicator light emits an indication signal based on the state factors of the scaffold in use collected by the data acquisition module, and the indicator light displays three colors of green, yellow and red according to the intensity and type of the signal to prompt the safety of the platform in use; when the platform is in a safe state, the indicator light displays green, indicating that the platform can be safely operated; in an embodiment, for example, the height is not high and the load is not heavy, at this time, the worker can normally use the platform.

[0080] When the platform is in a dangerous state, the indicator light displays yellow and simultaneously emits a prompt sound to prompt the worker to be cautious; for example, in a certain slope, a certain load, a high-altitude operation mode of more than 10 m, at this time, the use of the platform has certain dangerous factors, and the operation must be cautious.

[0081] If the worker continues to operate in violation of the rules in this mode, the platform will enter a restricted mode, the indicator light will turn red and emit an alarm sound, at this time, the platform will restrict all self-controlled actions, such as stopping moving, lifting and winch carrying goods, and will emit an alarm signal and notify the safety officer, who will immediately stop the worker's operation to avoid dangerous accidents; thereby effectively improving the worker's cognition of the use state of the platform, avoiding the safety risks caused by misoperation and improper operation, and better protecting the safety of personnel and property.

[0082] In order to better show the use process of the movable intelligent scaffold, the embodiment proposes a use method of the movable intelligent scaffold, which comprises the following steps:

[0083] S0, confirming the control right of the movable intelligent scaffold, first detecting whether there is a control right under the working platform, if there is a control right under the working platform, prohibiting the operator on the platform from controlling the movable intelligent scaffold, and controlling the platform by the worker under the working platform.

[0084] S1, by marking four support columns 3 as No. 1 rod, connecting rod 31 is marked as No. 2 rod; four support columns 3 are inserted at the four around of the bottom of the surface of base 1 and middle layer plate 4, and then three connecting rods 31 are inserted in parallel between the two support columns 3 at the front and rear ends of base 1, and the connection between the two ends of support column 3 and base 1 and middle layer plate 4 is locked and fixed by nut; then the ladder 32 is marked as No. 3 rod and No. 4 rod respectively, two No. 3 rods are symmetrically inserted at the center of the two ends of the surface of base 1, and are locked and fixed by nut; every four No. 4 rods are sequentially inserted through the inside of two support columns 3 and No. 3 rod on each side, and the two ends of No. 4 rod are locked and fixed by nut, thereby forming the ladder 32 on both sides;

[0085] S2, by marking four guide rods 41 as No. 5 rod, inserting them at the four around of the surface of middle layer plate 4, and locking and fixing the connection between the bottom of guide rod 41 and middle layer plate 4 by nut; then H-shaped vertical column 61 is symmetrically installed at the left and right ends of the surface of middle layer plate 4 by screw, and lifting mechanism 5 is symmetrically installed at the front and rear ends of the surface of middle layer plate 4 by fixed pin shaft 52;

[0086] S3, the pedal 7 is sleeved on the four guide rods 41, the sliding block 62 is connected with the two sides of the pedal 7 by screw, and the supporting leg assembly 2 is symmetrically installed on the two sides of the base 1 by hinge, thereby completing the assembly process of the intelligent scaffold; it should be noted that if the scaffold needs to be disassembled, the above nuts, screws and hinges are sequentially removed, and then a plurality of No. 1-5 rods are sequentially removed, thereby disassembling the scaffold for storage.

[0087] S4, the lifting mechanism 5 is controlled by the mobile control terminal to drive the pedal 7 to move downward to the lowest level, and the fence assembly 8 near the ladder 32 is lowered to the lowest level;

[0088] S5, the operator can climb to the pedal 7 through the ladders 32 on both sides, then pull the protective net 83 upward by hand holding the second spool 84, until the protective net 83 is pulled to the appropriate height, and the adjusting bolts 87 at both ends are inserted into the corresponding adjusting insertion holes 42 of the guide rods 41, so that the protective net 83 is temporarily fixed at this height, and the remaining three sides of the protective net 83 are pulled to the appropriate height according to this method;

[0089] S6, the electric push rod 55 of the lifting mechanism 5 is started by the mobile control terminal or the anti-collision display and platform height display instrument 9, the cross lifting frame 53 is expanded by the pushing force of the electric push rod 55, so that the pedal 7 is driven to rise along the H-shaped vertical column 61 to the appropriate height;

[0090] S7, the electric roller 12 is started by the mobile control terminal or the anti-collision display and platform height display instrument 9 to drive the whole scaffold to move;

[0091] S8. The moving speed and lifting speed of the lower rollers of the scaffold are collected sequentially through the data acquisition module. The levelness monitor and the slope display instrument 10 monitor the balance of the step 7. The load capacity monitor 20 monitors the load force of the step 7 and feeds back the monitored data to the control terminal, the anti-collision display and the platform height display instrument 9.

[0092] S9. The speed judgment module determines whether the monitored data exceeds the threshold. If it exceeds the threshold, a warning signal is sent to the mobile control terminal. The mobile control terminal sends a stop command to the emergency stop module and closes the electric push rod 55 or the electric roller 12 based on the emergency stop module, thereby controlling the scaffolding to stop rising or moving.

[0093] If on an uneven slope, after turning off the electric roller 12 in S10 and S9, the hydraulic cylinder 22 can be activated by the mobile control terminal or the anti-collision display and platform height display 9 to provide driving force. The hydraulic cylinder 22 pushes the hydraulic rod 23 and the support plate 24 to move down, and then the support plate 24 causes the extension shaft 25 to drive the support plate 26 to move down to the ground, thereby enhancing the stability of the scaffolding.

[0094] Working principle: By pulling the second roller 84, the protective net 83 is moved up to a suitable height, and the adjusting bolt 87 is inserted into the adjusting socket 42 of the guide rod 41, thereby temporarily fixing the protective net 83 at this height, thus enhancing the safety of the scaffold. By collecting the moving speed, lifting speed, balance and load of the lower rollers of the scaffold, and judging whether the collected data exceeds the threshold, if it does, the signal is sent to the mobile control terminal, which sends a stop command to the emergency stop module, thereby shutting off the electric push rod 55 or the electric roller 12 to control the scaffold to stop rising or moving, thus enhancing the monitoring of the scaffold during use.

[0095] like Figure 10 An emergency braking system is added to the lifting platform and other lifting equipment shown to ensure the safety of the workers.

[0096] The specific operation steps of the gravity limiter in this embodiment are as follows:

[0097] 1. Add a gravity limit switch module inside the lifting equipment. This module has a gravity limit sensor and is connected to the controller to detect the operating status of the lifting equipment and issue an emergency stop command. Simultaneously, this module can also monitor parameters such as the equipment's operating speed and load.

[0098] 2. When the lifting device starts, the gravity limiter module begins to monitor the running state of the device. If it detects that the lifting displacement and the torque used are in an abnormal state, for example, the lifting device is blocked by an obstacle and continues to lift, the torque caused by the blockage will increase significantly, but the lifting displacement remains unchanged, the controller will issue an emergency stop command.

[0099] 3. After receiving the emergency stop command, the device is stopped.

[0100] 4. After the device stops, the gravity limiter module is automatically reset for the next use.

[0101] The advantage of this embodiment is that by adding the gravity limiter module, the emergency stop function can be realized, improving the safety of the lifting device. The emergency stop measure can be started immediately when the device is stuck or other faults occur, avoiding accidents. In addition, the gravity limiter can also monitor the running state of the device, detect whether the device is overloaded or overspeed, etc., making the stop more reliable and accurate. The principle is that when the scaffold or platform automatically adjusts the lifting, the lifting force and lifting displacement are in a certain proportional relationship, but when it is blocked by an obstacle, the lifting displacement remains unchanged, and the force continues to lift. Therefore, this gravity limiter module is used, and if the force and displacement exceed the limit, the lifting power is cut off. Preventing damage to the device caused by encountering the floor or support during lifting, or damaging the floor or support.

[0102] Avoid the limitations that traditional scaffolds may not be able to enter the construction site entrance or elevator.

[0106] 2. On-site assembly: On-site workers follow the assembly drawings and instructions to find the corresponding parts according to the numbers for assembly until the entire scaffold assembly is completed. The height and width can be freely configured according to actual needs.

[0107] 3. Move and fix: The bottom of the scaffold is designed with a set of moving wheels, which can be easily moved to the desired position and fixed to ensure safe use.

[0108] 4. Intelligent control system: The scaffold is equipped with an intelligent control system, which can be controlled by a remote controller or a mobile phone APP to perform operations such as raising, lowering, rotating, and moving the scaffold.

[0109] 5. Safety protection: The scaffold is equipped with various safety protection systems, such as anti-falling safety locks, anti-slip pedals, safety fences, and others.

[0110] 6. Disassembly and storage: The scaffold is assembled in scattered parts, so it is very convenient to disassemble and store, and it does not occupy too much space.

[0111] Through the above scheme, the movable scaffold is assembled in scattered parts, which is convenient for on-site assembly and movement, and can improve the construction efficiency and safety. At the same time, the size and height of the scaffold can be freely configured according to actual needs to adapt to the requirements of different engineering projects, with wide applicability and scalability.

[0112] Further including a scaffold fixed slope lower support foot anti-overturning support foot module, characterized by adding a tilt angle sensing and automatic warning function, and an extensible third support foot module, realizing more secure and reliable operation. The specific implementation scheme is as follows:

[0113] 1. Sensing tilt angle: The scaffold is equipped with a tilt angle sensing device that can sense the inclination of the scaffold in real time and the inclination angle.

[0114] 2. Automatic warning: When the inclination angle of the scaffold exceeds the preset value, such as about 10°, the system will automatically issue a warning and brake the scaffold to prevent further inclination and overturning.

[0115] 3. Third support foot module: A third support foot module is added to the bottom of the scaffold. When the scaffold is inclined, the operator installs a third support foot below to increase the stability and load-bearing capacity of the scaffold. The third support foot module can be adjusted and installed according to different scaffold sizes and inclination degrees.

[0116] 4. Automatic warning elimination: When the third support foot is installed, the system will automatically sense the stable state of the scaffold and eliminate the warning, allowing the operator to continue the construction work.

[0117] Through the above implementation scheme, the design and application of the scaffold fixed slope lower support foot anti-overturning support foot module are realized, which enhances the stability and safety of the scaffold and greatly reduces the risk of accidents. At the same time, this scheme can be customized and expanded to meet the requirements and needs of different engineering projects.
