In this embodiment, the rail connection mechanism 3 is responsible for mounting the apparatus to the target work area. By adjusting the contact pressure between the device and the ring crane guide rail 1, the device can be ensured to be stable in the whole operation process, and the risk of position deviation or falling caused by external interference is avoided. According to the specific working environment, the contact pressure between the guide rail connecting mechanism 3 and the ring crane guide rail 1 is adjusted until a preset standard value is reached, and the guide rail connecting mechanism 3 is connected with the ring crane guide rail 1 through bolts.
When everything is ready, the device is smoothly pushed to the target working area by using the ring crane guide rail 1. At this time, special attention should be paid to observe whether any abnormal vibration or inclination signs are present. If any problem is found, the operation is stopped immediately and readjusted. The worker enters the interior of the work platform assembly 4 through the entrance door 212, properly connects his or her own seat belt to the designated hooking portion, and starts the final attaching/detaching operation of the decorative board.
Referring to fig. 1-2 and fig. 4, in some embodiments, the adjustable lower support mechanism 5 includes a vertical displacement executing component disposed below the support frame component 2, and gesture detection feedback components distributed on the support frame component 2, where the vertical displacement executing component and the gesture detection feedback components form a closed-loop regulation device, so as to jointly implement a dynamic leveling function of the working platform component 4. The vertical displacement executing assembly comprises a hydraulic lifting column 51, and the gesture detection feedback assembly comprises a horizontal calibration device 52 and an emergency mechanical locking mechanism 53, and the emergency mechanical locking mechanism is used for realizing self-locking when the hydraulic lifting column 51 fails.
In this embodiment, the hydraulic lifting column 51 is a component for height adjustment. By controlling the pressure change of the hydraulic oil, the hydraulic lifting column 51 can be moved up and down, thereby adjusting the height of the support frame assembly 2. The device is convenient for operators to flexibly adjust the working position according to actual demands, and the connection with the ring crane guide rail 1 is more convenient and quicker.
The leveling device 52 is coupled to the hydraulic lifting column 51, and the leveling device 52 is mainly used for maintaining the leveling of the whole structure during the height adjustment process, because any inclination may cause inaccurate or unstable assembly.
The emergency mechanical locking mechanism 53 is provided as an additional safety measure in view of the potential failure risk of the hydraulic system. When the hydraulic system fails, the mechanism can be automatically started to lock the current height position, and the equipment is prevented from being damaged or damaged due to accidental descent.
In actual operation, these three major components mate:
Firstly, an operator sends a command to the hydraulic lifting column 51 through the control system to enable the hydraulic lifting column to ascend or descend to a required height;
In the process, the horizontal calibration device 52 monitors and adjusts in real time, so as to ensure that the platform is always kept horizontal;
In the event of a hydraulic leak or other emergency, the emergency mechanical locking mechanism 53 is immediately interposed to ensure the safety of the operator and equipment.
The preparation time is reduced, the working efficiency is improved through quick and accurate height adjustment, the safety of the system is remarkably improved by introducing an emergency locking mechanism, the accident risk is reduced, construction errors caused by the inclination of the platform can be effectively avoided by means of the horizontal calibration device 52, and the engineering quality is ensured.
The horizontal calibration device 52 includes four groups of high-precision inclination sensors (installed at four corners of the supporting frame assembly 2), a hydraulic balance valve group and an actuating mechanism. The levelness of the support frame assembly 2 is monitored in real time, the telescopic quantity of the hydraulic lifting columns 51 is controlled through PLC feedback, the height difference of each column is automatically adjusted, and the level of the support frame assembly 2 is ensured. When any inclination sensor detects that the inclination exceeds a threshold value, the hydraulic balance valve group is triggered, and the corresponding hydraulic column is driven to finely adjust and lift until the horizontal error is eliminated.
The emergency mechanical locking mechanism 53 is constituted by a ratchet and pawl brake. When the hydraulic system fails (such as insufficient oil pressure or circuit failure), the hydraulic cylinder is forced to be locked through mechanical linkage, so that the lifting column is prevented from accidentally falling. Automatic triggering, namely automatically starting pawl braking when the PLC detects that the hydraulic pressure is lower than a safety threshold value. And the manual triggering is that the lock is directly locked through an operation handle, and the lock can be unlocked after the manual resetting is needed.
Finally, it should be pointed out that the above detailed method and apparatus are only examples, which can be modified in different ways by a person skilled in the art without departing from the scope of the invention.
