Description

Technical Field

[0001] This invention relates to the field of high-altitude work equipment technology, and in particular to an anti-tipping hydraulic stabilizing outrigger for a high-altitude curtain wall maintenance platform and its adjustment method. Background Technology

[0002] The number of super high-rise buildings in China is increasing. When high-rise buildings appear in the form of twin towers, the two towers are often connected by a high-altitude bridge. Furthermore, since high-rise buildings often use curtain walls to enhance their aesthetic appeal, high-altitude curtain wall maintenance platforms are generally used for the maintenance and repair of these curtain walls.

[0003] High-altitude curtain wall maintenance platforms must withstand wind loads, equipment weight, and operator loads during operation. Traditional support leg structures have the following drawbacks:

[0004] 1. Insufficient stability: The outriggers have a small contact area with the ground, resulting in weak resistance to overturning;

[0005] 2. Low adjustment efficiency: Manually adjusting the height of the outriggers is time-consuming and labor-intensive, and cannot quickly adapt to uneven ground;

[0006] 3. Poor safety: The lack of real-time monitoring and feedback mechanisms makes it prone to overturning due to loose outrigger connections or ground subsidence. Summary of the Invention

[0007] This invention provides an anti-tipping hydraulic stabilizing outrigger for a high-altitude curtain wall maintenance platform to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An anti-tipping hydraulic stabilizing outrigger for a high-altitude curtain wall maintenance platform includes a maintenance platform with four outrigger mechanisms. Each outrigger mechanism includes a hydraulic cylinder and a support base. The support base is located below the hydraulic cylinder and connected to the output end of the hydraulic cylinder. Pressure sensors are installed on the bottom sides of the four support bases, and a tilt sensor is installed on the central bottom side of the maintenance platform. The platform also includes a controller. The hydraulic cylinders, tilt sensors, and pressure sensors are all connected to the controller. The controller is used to adjust the extension and retraction of each hydraulic cylinder to prevent the maintenance platform from tipping over.

[0010] A method for adjusting the anti-tipping hydraulic stabilizing outriggers of a high-altitude curtain wall maintenance platform is also disclosed, specifically including:

[0011] The first step is to acquire pressure data at the bottom of the four support bases using pressure sensors, and simultaneously acquire the X-axis tilt angle θ of the maintenance platform using tilt sensors. x and the Y-axis tilt angle θ yThe pressure data detected by the pressure sensor and the X-axis tilt angle and Y-axis tilt angle detected by the tilt sensor are output to the controller.

[0012] The second step involves the controller calculating the pressure deviation and tilt angle deviation.

[0013] The third step is to calculate the target height adjustment amount for each outrigger based on the tilt angle deviation, and then correct the target height adjustment amount by introducing the pressure deviation to obtain the corrected adjustment amount:

[0014] The fourth step is to prevent over-adjustment of a single leg by introducing dynamic weights to further adjust the correction amount, thus obtaining the final adjustment amount for each hydraulic cylinder.

[0015] Fifth, the controller adjusts the corresponding hydraulic cylinders by the final adjustment amount of each hydraulic cylinder until the X-axis tilt angle and Y-axis tilt angle of the maintenance platform are both less than the safe angle, then the adjustment stops.

[0016] Preferably, the second step is to calculate the pressure deviation, specifically: ΔP i =P i -P nom , where ΔP i For pressure deviation; P i P represents the pressure at the bottom of the i-th support base, where i ∈ [1, 4]; nom The rated pressure of the hydraulic cylinder.

[0017] Preferably, the second step is to calculate the tilt angle deviation, specifically: Δθ x =θ x -θ target-x , Δθ y =θ y -θ target-y ;

[0018] Where, Δθ x The X-axis angular deviation of the maintenance platform; Δθ y The Y-axis angle deviation of the maintenance platform; θ x θ is the X-axis tilt angle of the maintenance platform. y θ is the Y-axis tilt angle of the maintenance platform. target-x θ represents the target angle along the X-axis. target-y θ represents the target angle along the Y-axis. target-x =θ target-y =0.

[0019] Preferably, the target height adjustment amount of each outrigger mechanism is calculated based on the X-axis angle deviation and the Y-axis angle deviation, specifically as follows:

[0020] Δh i =k 1· Δθ x ·Lix +k 2· Δθ y ·L iy ;

[0021] Among them, L ix L iy Let be the lengths of the X and Y axes of the support base of the i-th outrigger mechanism from the center of the platform; k1 and k2 are proportionality coefficients, k1 = k2 = 0.5; Δh i The target height adjustment amount for the outrigger mechanism.

[0022] Preferably, the target height adjustment amount is adjusted by introducing pressure deviation correction, specifically as follows:

[0023]

[0024] Where α is the pressure correction factor, P max This represents the maximum permissible pressure on the outrigger.

[0025] Preferably, α is 0.2.

[0026] Preferably, in the fourth step, to prevent over-adjustment of a single leg, dynamic weights are introduced to calculate the final adjustment amount, specifically as follows:

[0027] First, calculate the dynamic weights.

[0028] Then calculate the final adjustment amount.

[0029] in, w represents the final height adjustment amount of the i-th outrigger mechanism. i Let be the dynamic weight of the i-th outrigger mechanism.

[0030] Preferably, the safety angle in step five is 0.5°.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] This invention achieves rapid leveling, automatic locking, and real-time monitoring of the outriggers through hydraulic drive, intelligent control, and structural optimization, ensuring that the platform remains level under complex working conditions.

[0042] Please see Figures 1-2In this embodiment of the invention, an anti-tipping hydraulic stabilizing outrigger for a high-altitude curtain wall maintenance platform includes a maintenance platform 4, on which four outrigger mechanisms are provided.

Pressure sensors 6 are provided on the bottom sides of the four support bases 2, and tilt sensors 5 are provided on the central bottom side of the maintenance platform 4. The platform also includes a controller 3, to which the hydraulic cylinder 1, tilt sensors 5, and pressure sensors 6 are all connected. The controller 3 is used to adjust the extension and retraction of each hydraulic cylinder 1 to prevent the maintenance platform 4 from tipping over.

[0043] A method for adjusting the anti-tipping hydraulic stabilizing outriggers of a high-altitude curtain wall maintenance platform, specifically including:

[0044] The first step involves acquiring pressure data at the bottom of the four support bases 2 using pressure sensors 6, and simultaneously acquiring the X-axis tilt angle θ of the maintenance platform 4 using tilt sensors 5. x and the Y-axis tilt angle θ y The pressure data detected by the pressure sensor 6 and the X-axis tilt angle and Y-axis tilt angle detected by the tilt sensor 5 are output to the controller 3; the controller 3 can be set on the maintenance platform 4.

[0045] The second step involves controller 3 calculating the pressure deviation and tilt angle deviation, specifically:

[0046] ΔP i =P i -P nom , where ΔP i For pressure deviation; P i P represents the pressure at the bottom of the i-th support base 2, where i ∈ [1, 4]; nom Rated pressure of hydraulic cylinder 1.

[0049] The third step is to calculate the target height adjustment for each outrigger based on the tilt angle deviation:

[0050] Δh i =k 1· Δθ x ·L ix +k 2· Δθ y ·L iy ;

[0051] Among them, L ix L iy Let be the lengths of the X and Y axes of the support base 2 of the i-th outrigger mechanism from the center of the platform; k1 and k2 are proportionality coefficients, k1 = k2 = 0.5; Δh i The target height adjustment amount for the outrigger mechanism.

[0053] Where α is the pressure correction factor, P max The maximum allowable pressure of the outrigger is α, which is 0.2 in this embodiment.

[0054] The fourth step, to prevent over-adjustment of a single leg, introduces dynamic weights and calculates the final adjustment amount, specifically:

[0055] First, calculate the dynamic weights.

[0056] Then calculate the final adjustment amount.

[0057] in, w represents the final height adjustment amount of the i-th outrigger mechanism. i Let be the dynamic weight of the i-th outrigger mechanism;

[0058] Fifth step, the controller makes the final adjustment. The calculation results are used to adjust the extension and retraction of the hydraulic cylinder on the i-th outrigger until the platform tilt angle θ is reached. x θ y When all angles are less than 0.5° of the safe angle, the adjustment is stopped to achieve dynamic leveling.
