Description

Technical Field

[0001] The utility model relates to the field of attached scaffolding control, in particular to an attached scaffolding leveling system based on satellite positioning technology. Background Art

[0002] During the lifting process of the attached scaffolding, due to performance differences between the electric hoists, obstacles, abnormal friction and other factors, the lifting of each motor may be out of sync, which will cause the frame to tilt, increase the load on certain hanging points, cause local damage, and then cause the frame to fall, resulting in casualties and property losses. The current mainstream attached scaffolding synchronization control system uses gravity sensors to monitor the load at each machine position in real time. When a load signal is too large, a warning is issued and the operation is stopped. However, in addition to the tilt of the attached scaffolding, the reasons for the excessive load signal may also be obstacles, uneven load on the frame, or sensor failure. Relying solely on load monitoring sometimes cannot fully guarantee the balance of the frame during lifting and lowering, thus causing safety hazards. Utility Model Content

[0003] The purpose of the utility model is to provide an attached scaffolding leveling system based on satellite positioning technology, which is used in conjunction with a traditional gravity sensor to form a new synchronous control system, which is not only safer and more reliable, but also convenient for remote monitoring and control.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an attached scaffolding leveling system based on satellite positioning technology, comprising a satellite signal measuring terminal, a communication platform and a central control system; a plurality of the satellite signal measuring terminals are installed on the outside of the frame of the attached scaffolding, the satellite signal measuring terminal is connected to the communication platform in real time via the network, the communication platform is connected to the central control system in real time via Bluetooth, the network or wired, and the central control system is connected to each electric hoist of the attached scaffolding.

[0005] The satellite signal measurement terminal is powered by the existing circuit of the attached scaffolding to ensure long-term stable operation.

[0006] The satellite signal measurement terminal accesses the network via the local 4G signal and can transmit the satellite signal monitoring data to the communication platform in real time.

[0007] The attached scaffolding comprises a straight section and a corner. A satellite signal measurement terminal is installed every 6 to 10 meters on the straight section, and a satellite signal measurement terminal is installed at the corner.

[0008] It also includes a reference station, which is used to improve the monitoring accuracy of the satellite signal measurement terminal. Therefore, when the construction site is far away from the public reference station, an additional reference station can be installed in an open area of ​​the construction site to ensure accuracy.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model reasonably arranges multiple satellite signal measurement terminals, utilizes satellite positioning technology to monitor the elevation information of each section of the frame of the attached scaffolding in real time, and can directly control the height difference of the entire frame to ensure the balance of the attached scaffolding during the lifting process, so that during the lifting process of the attached scaffolding, the entire frame is always in a level state and is not affected by various shapes and sizes of the building's facade, completely eliminating the safety hazards caused by imbalance during the lifting process of the frame, and further improving the safety performance of the attached scaffolding during the lifting process.

[0013] See also Figure 1 to Figure 2 , Figure 1 The direction of the arrow in the middle is the direction of signal transmission. Figure 2 The arrow direction is the process sequence direction. The utility model discloses a leveling system for an attached scaffold 5 based on satellite positioning technology and a corresponding leveling method. The leveling system includes a satellite signal measurement terminal 1, a communication platform 2 and a central control system 3.

[0014] See also Figure 1, the attached scaffolding 5 is installed on the outer circle of the floor 6, and the satellite signal measurement terminal 1 is installed on the outside of the frame of the attached scaffolding 5. The frame of the attached scaffolding 5 mainly includes two structures, one is the straight section structure, and the other is the "L"-shaped structure at the corner. The utility model is used in conjunction with a gravity sensor. In order to save costs and balance the frame structure, the satellite signal measurement terminal 1 needs to be installed on both structures. The straight section structure itself has a certain rigidity and is pieced together by shorter basic structures. The length of the basic structure is about 2 meters. Therefore, a measurement terminal is placed every 3 to 5 basic structures, that is, a satellite signal measurement terminal 1 is set every 6 to 10 meters on the straight section. The "L"-shaped structure at the corner is connected to the two straight sections, and a satellite signal measurement terminal 1 needs to be set separately at the right angle. The satellite signal measurement terminal 1 monitors the elevation signal of the attached scaffolding 5 frame based on RTK technology, and the monitoring accuracy can reach millimeter level. The satellite signal measurement terminals 1 are all in an open environment, directly facing the sky, avoiding various signal interferences on the construction site and improving the positioning accuracy. When the construction site is far away from the public reference station, a reference station 4 may be arranged at the construction site to improve the monitoring accuracy of the satellite signal measurement terminal 1 .

[0015] All satellite signal measurement terminals 1 and the motor for controlling the lifting of the attached scaffold 5 are in the same circuit, using stable circuit power supply, without the need for additional batteries, thus saving costs and enabling long-term stable operation.

[0016] See also Figure 2 The communication platform 2 is a mobile phone or computer connected to the Internet. Multiple satellite signal measurement terminals 1 transmit satellite signals to the equipment supplier's server via 4G signals. After RTK conversion, the elevation signal with the required accuracy is transmitted to the communication platform 2 via the network. Then the communication platform 2 instantly calculates the maximum height difference of the entire frame. The communication platform 2 can be located at the construction site, or placed in the office, or there can be multiple ones.

[0017] The central control system 3 is located on the second top floor 6 of the building under construction, and controls all electric hoists on the attached scaffolding 5. The central control system 3 is connected to the communication platform 2 via Bluetooth, network or wired, and receives the maximum height difference signal from the communication platform 2 in real time. When the maximum height difference between the entire frame of the attached scaffolding 5 obtained in real time from the communication platform 2 reaches 3cm during the lifting process, the central control system 3 will automatically stop the lifting immediately. When the lifting process of the attached scaffolding 5 stops, the electric hoist is controlled manually or automatically to level the entire frame. After leveling, the attached scaffolding is controlled by the central control system 3 to lift and lower.

[0018] In summary, the utility model reasonably arranges multiple satellite signal measurement terminals and uses satellite positioning technology to monitor the elevation information of each section of the frame of the attached scaffolding in real time, and can directly control the height difference of the entire frame to ensure the balance of the attached scaffolding during the lifting process. During the lifting process of the attached scaffolding, the entire frame is always in a level state and is not affected by various shapes and sizes of the building's facade. The safety hazards caused by imbalance during the lifting process of the frame are completely eliminated, and the safety performance of the attached scaffolding during the lifting process is further improved.
