In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The present invention provides Figure 1-7 A lifting device for electromechanical installation shown in the figure includes a lift 1. The lift 1 adopts a hydraulic lifting platform, and includes, from top to bottom, a storage platform 101, a lifting mechanism 102 and a base 103. The storage platform 101 is used for workers and for placing pipes, air ducts, electromechanical accessories, etc. during electromechanical installation. The lifting mechanism 102 includes but is not limited to a scissor-type hydraulic lifting structure. The base 103 is used for stable support of the lift 1, and moving wheels 104 are installed at the bottom corners of the base 103. The moving wheels 104 include but are not limited to electric drive for the movement of the lift 1. An upward extending ladder 30 is fixedly installed on one side of the base 103 to facilitate access to the storage platform 101.

[0039] The present invention provides Figure 2 and 4 Embodiment 1 shown:

[0040] The bottom corners of the base 103 are fixedly installed with lifting columns 5, the axis of the lifting columns 5 is vertically arranged, and the output end is downward, and the output end of the lifting columns 5 is coaxially fixedly installed with a support plate 31, and the horizontal cross-sectional area of ​​the support plate 31 is larger than the cross-sectional area of ​​the output end of the lifting columns 5, so as to improve the stability of the lifting columns 5 supporting the lift 1. The lifting columns 5 adopt hydraulic lifting columns, and the supporting stability is strong. The lifting columns 5 are used to extend the output end of the lifting columns 5 to prop up the lift 1 when the lift 1 moves to the designated working position, so as to ensure the stable placement of the lift 1;

[0041] A pressure sensor 6 is embedded in the bottom of the support plate 31, and the detection end of the pressure sensor 6 faces outward and protrudes from the support plate 31. When the lifting column 5 supports the lift 1, it is used to detect the stress conditions of the lift 1 at multiple angles.

[0042] The lifting column 5 is adapted to the pressure sensor 6. When the pressure value of the pressure sensor 6 on one side or one corner of the base 103 decreases or returns to zero, the output end of the lifting column 5 on the opposite side extends out to adjust the horizontal state of the base 103 to prevent the lift 1 from tipping over.

[0043] An annular slide rail 7 is fixedly installed inside the base 103, and the axis of the annular slide rail 7 is vertical and coincides with the center of the elevator 1. The annular slide rail 7 adopts an electric slide rail, which includes an annular guide rail part and a sliding part, and also includes a linear slide rail 3. The linear slide rail 3 adopts an electric slide rail, which includes a linear guide rail part and a sliding part. The linear guide rail part of the linear slide rail 3 is horizontally arranged, and one end bottom is rotatably installed at the center of the base 103, and the other end lower part is hinged to the sliding part of the annular slide rail 7. The linear guide rail part of the linear slide rail 3 rotates in a circle like a clock pendulum under the drive of the sliding part of the annular slide rail 7, and a counterweight block 4 is fixedly installed on the sliding part of the linear slide rail 3. The counterweight block 4 moves within its movable range under the drive of the linear slide rail 3 and the annular slide rail 7, and is used to move to one side of the base 103 before or after pre-tilting to increase the counterweight to prevent the elevator 1 from tipping over, and is adapted to the pressure sensor 6 to achieve automatic adjustment.

[0044] A main controller 2 is also installed on the elevator 1. The main controller 2 includes but is not limited to a PID controller. The linear slide 3, the lifting column 5, the pressure sensor 6 and the annular slide 7 are all connected to the main controller 2 for information transmission. The movements of the linear slide 3, the lifting column 5 and the annular slide 7 are automatically controlled by an algorithm. The horizontal stability of the base 103 is adjusted under the dual effects of the lifting of the lifting column 5 and the movement of the counterweight 4 to prevent the elevator 1 from tipping over.

[0045] The present invention also provides an algorithm of embodiment 1, including but not limited to the steps of using the algorithm:

[0046] 1. Data Collection

[0047] Objective: To obtain the pressure data of the pressure sensor 6 at the bottom of the lifting column 5 to detect the tilt condition.

[0048] Data reading: real-time collection of pressure data from multiple pressure sensors 6.

[0049] 2. Tilt detection

[0050] Objective: Determine whether elevator 1 is tilted based on pressure data.

[0051] Pressure difference calculation: Calculate the pressure difference of multiple pressure sensors 6. In theory, the pressure at the base 103 should be equal. If there is a tilt, there will be a significant pressure difference.

[0052] For example: Calculate the pressure difference ΔP:

[0053] ΔP=max(P1, P2, P3, P4)-min(P1, P2, P3, P4);

[0054] If ΔP exceeds a preset threshold, it is considered that the elevator is tilted.

[0055] 3. Balance control

[0056] Objective: Use the lifting column 5 and the counterweight 4 to adjust the base 103 to keep it level.

[0057] Lifting column 5 adjustment:

[0058] Calculate the required adjustment amount of each lifting column 5. Assuming that the target pressure of each lifting column 5 is Ptarget, the adjustment amount ΔPi of each lifting column 5 needs to make the pressures of multiple lifting columns 5 as close as possible.

[0059] Adjustment formula example:

[0060] ΔPi=Ptarget-Pi / K;

[0061] Where K is the control gain, which is set according to actual conditions.

[0062] Counterweight 4 movement:

[0063] According to the tilt direction and degree, the movement of the counterweight is calculated, and the movement can be adjusted symmetrically to achieve balance;

[0064] Calculate the adjustment amount ΔWi of each counterweight block and adjust it within the motion range of the counterweight block;

[0065] Adjustment formula example:

[0066] ΔWi=f(ΔP);

[0067] Where f(ΔP) is the relationship function between the pressure difference and the movement of the counterweight, which is determined based on actual tests.

[0068] 4. Control algorithm

[0069] Goal: Control in real time to keep lift 1 level.

[0070] The PID controller performs feedback control on the pressure difference to adjust the lifting column 5 and the counterweight block 4 in real time. The PID controller calculates the output control amount and adjusts the lifting column 5 and the counterweight block 4 to reduce the tilt;

[0071] Control algorithm example:

[0072] u(t)=Kpe(t)+Ki∫t0e(τ)dτ+Kddet / dt;

[0073] Where e(t) is the error, and Kp, Ki, and Kd are the proportional, integral, and derivative gains.

When the detection value of the pressure sensor 6 on one side of the elevator 1 returns to zero, it is determined that this side is tilted, and the second motor 28 starts to drive the active gear 27 to rotate. The active gear 27 drives the driven gear 26 meshing with it to rotate. The rotation of the driven gear 26 drives the spring 24 to move to the opposite side of the zeroing pressure sensor 6. The spring 24 and the opening 25 on this side are prepared for protection. When the detection value of the pressure sensor 6 on the lower side of the spring 24 also returns to zero, it is determined that the elevator 1 has tipped over.
