[0001] This disclosure relates to the field of automation, specifically to a cylinder cat claw load distribution device, equipment, method, and medium. Background Technology

[0002] Normally, the cylinder is supported by four claws at the front, rear, left, and right ends on bearing seats or a dedicated base platform. During installation or maintenance, the load distribution and levelness of the cylinder are adjusted using shims at the bottom of the four claws to ensure that the cylinder can extend and retract freely during operation. If the load distribution of the cylinder is uneven, it will cause obstruction during the expansion and contraction of the cylinder, affecting its normal operation.

[0003] Current cylinder cat's paw load distribution methods include the cat's paw vertical arc method, differential pressure method, and force gauge method. These methods rely entirely on manual measurement and adjustment, resulting in low testing accuracy and significant waste of manpower and resources. Furthermore, these methods use estimation techniques, requiring multiple adjustments to meet the final standard, leading to low work efficiency. Therefore, improving the efficiency and testing accuracy of cylinder cat's paw load distribution is one of the urgent technical problems to be solved. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the background technology, this disclosure provides a cylinder cat paw load distribution device, equipment, method and medium, which can realize the automation of cat paw load distribution and improve the accuracy and working efficiency of cat paw load distribution.

[0005] Firstly, this application provides a cylinder cat claw load distribution device, which includes a lifting device, a pressure detection device, a displacement detection device, a data acquisition module, and a controller. The lifting device is correspondingly arranged below multiple cat claws to drive the corresponding cat claws to move vertically. The pressure detection device is arranged on the lifting device to measure the pressure value during the lifting device's movement of the cat claws and generate a corresponding pressure detection signal. The displacement detection device is correspondingly arranged on the lifting device to measure the vertical displacement value of the cat claws and generate a corresponding displacement detection signal. The data acquisition module is electrically connected to both the pressure detection device and the displacement detection device to process and convert the received pressure detection signal and displacement detection signal to generate a corresponding digital signal. The controller is electrically connected to the data acquisition module to obtain the height-pressure correlation of each cat claw, obtain the pressure value and displacement value based on the received digital signal, and calculate the target shim adjustment amount of the cat claws based on the pressure value or displacement value and the height-pressure correlation. After the shims under each cat claw are adjusted by the target shim adjustment amount, the load difference at the lateral symmetrical position of each cat claw meets a preset standard.

[0006] In the cylinder cat claw load distribution device of the above embodiment, the lifting device can drive each cat claw to move vertically to obtain the changes in pressure detection signals and displacement detection signals generated by the pressure detection device and displacement detection device. The data acquisition module processes and converts the received pressure detection signals and displacement detection signals. The controller can obtain the height-pressure correlation of each cat claw based on the corresponding changes between the pressure value and displacement value of each cat claw obtained by the data acquisition module. Based on the pressure value or displacement value and the height-pressure correlation, the controller calculates the target shim adjustment amount of each cat claw, thereby realizing cylinder cat claw load distribution, reducing measurement and adjustment errors caused by manual operation, improving the working efficiency of cylinder cat claw load distribution, and avoiding delays in project schedule due to cylinder cat claw load distribution.

[0007] In one embodiment, the cylinder cat paw load distribution device includes: a shim having a preset thickness; a load difference value at the lateral symmetrical position of the cat paw including a pressure difference value at the lateral symmetrical position; a preset standard including a pressure difference standard; and a controller configured to:

[0008] Based on the vertical displacement value of each cat paw, the preset thickness value of the pad, the pressure value, and the height-pressure relationship, calculate the test pressure value of each cat paw; calculate the pressure difference value of the cat paw at the lateral symmetrical position based on the test pressure value of each cat paw; and output the target pad adjustment amount when the pressure difference value at the lateral symmetrical position meets the corresponding pressure difference standard.

[0009] In one embodiment, the cylinder cat paw load distribution device includes: a load difference value for the lateral symmetrical position of the cat paw including a pressure difference value for the lateral symmetrical position; a preset standard including a pressure difference standard; and a controller configured to: calculate the target shim adjustment amount for each cat paw based on the original shim thickness and the height-pressure correlation; the original shim thickness is the shim thickness under each cat paw before adjustment.

[0010] In one embodiment, the controller is configured to: acquire the relationship between the vertical displacement value of the cat paw and the corresponding pressure value during the process in which each cat paw is driven by the corresponding lifting device to the same vertical displacement value; and / or acquire the correspondence between the vertical displacement value of the cat paw and the corresponding pressure value during the process in which each cat paw is driven by the corresponding lifting device to the same lifting pressure value to the different vertical displacement values.

[0011] In one embodiment, the cylinder cat paw load distribution device further includes: a display, connected to the controller, for displaying the target shim adjustment amount that each cat paw under shim should be adjusted, and the expected value after adjustment.

[0012] In one embodiment, the cylinder cat paw load distribution device includes at least one of the following:

[0013] The lifting device includes a hydraulic lifting device, which is connected to the data acquisition module; the pressure detection device includes a pressure sensor, which is connected to the data acquisition module; and the displacement detection device includes a displacement sensor, which is connected to the data acquisition module.

[0014] In one embodiment, the data acquisition module includes an amplifier circuit and a digital-to-analog converter circuit. The amplifier circuit is connected to the pressure detection device and / or the displacement detection device and is used to amplify the received pressure detection signal and / or displacement detection signal. The digital-to-analog converter circuit is connected to the amplifier circuit and is used to perform digital-to-analog conversion on the amplified pressure detection signal and / or displacement detection signal to generate a corresponding digital signal.

[0015] Secondly, this application also provides a testing device, which includes the cylinder cat claw load distribution device in any embodiment of this disclosure.

[0016] Thirdly, this application also provides a cylinder cat's paw load distribution method, including:

[0017] A lifting device, corresponding to multiple cat paws, drives the corresponding cat paws to move vertically. A pressure detection device on the lifting device measures the pressure value during the movement of each cat paw and generates a corresponding pressure detection signal. A displacement detection device, also corresponding to the lifting device, measures the vertical displacement value of each cat paw and generates a corresponding displacement detection signal. A data acquisition module processes and converts the received pressure and displacement detection signals to generate corresponding digital signals. Based on the received digital signals, the pressure and displacement values ​​are obtained, the height-pressure correlation of each cat paw is acquired, and the target shim adjustment amount for each cat paw is calculated based on the height-pressure correlation. After the shims under each cat paw are adjusted by the target shim adjustment amount, the load difference at the lateral symmetrical position of the cat paws meets the preset standard.

[0018] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the cylinder cat claw load distribution method in any embodiment of this disclosure.

[0019] The aforementioned cylinder cat claw load distribution device, equipment, method, and computer-readable storage medium utilize a lifting device positioned beneath multiple cat claws to drive their vertical movement. Pressure and displacement detection devices measure the pressure and displacement signals of the cat claws during this vertical movement. A data acquisition module processes and converts these signals to generate corresponding digital signals, ensuring measurement accuracy. A controller acquires the height-pressure correlation of each cat claw, obtains pressure and displacement values ​​based on the received digital signals, and calculates the target shim adjustment amount based on the pressure, displacement, and height-pressure correlation. This improves the efficiency of cat claw load distribution. After adjustment based on the target shim adjustment amount, the load difference at the lateral symmetrical positions of each cat claw meets a preset standard. This avoids the need for multiple manual trials and adjustments to complete the cat claw load distribution, improving testing accuracy and work efficiency, and preventing the impact of traditional manual methods on project schedules.

However, this disclosure may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Current cylinder load distribution methods include the cat's paw vertical arc method, the differential pressure method, and the force gauge method. The cat's paw vertical arc method involves setting up dial indicators vertically on the four paws to monitor displacement, sequentially removing the shims under each of the four paws, observing the corresponding dial indicator readings, and adjusting each paw individually based on these readings. This process is repeated until the difference in dial indicator readings at symmetrical lateral positions is less than or equal to a preset accuracy value, such as 0.1mm. The differential pressure method involves setting up jacks at the bottom of the four paws, gradually raising each paw, and adjusting the shims based on the relationship between height and load until the load difference at symmetrical positions meets the requirements. The force gauge method uses a force gauge to measure the load on the four paws until the force gauge value is adjusted to the design value, and then adjusting the shims based on the paw height at this point. All three methods involve multiple adjustments and gradual approximation, making them highly dependent on manual labor, and manual measurement using measuring tools is prone to errors.

[0031] Based on this, this application provides a cylinder cat claw load distribution device, equipment, method and medium, which can improve the working efficiency and measurement accuracy of cat claw load distribution, reduce the waste of manpower and material resources and shorten the construction period.

[0032] Please refer to Figure 1In some embodiments, this application provides a cylinder cat paw load distribution device 100 for quickly and accurately distributing the load of the cylinder cat paws. The cylinder cat paw load distribution device includes: a lifting device 110, a pressure detection device 120, a displacement detection device 130, a data acquisition module 140, and a controller 150. The lifting device 110 is correspondingly arranged with multiple cat paws and is located below the corresponding cat paws to drive the corresponding cat paws to move vertically. The lifting device 110 includes a lifting execution module 111 and a power control module 112. The lifting execution module is used to drive the corresponding cat paws to move vertically, and the power control module is used to control the lifting driving force. Different driving forces cause the cat paws to move to different heights. The pressure detection device 120 is arranged on the lifting execution module 111 to measure the pressure value during the lifting device's movement of each cat paw and generate a data acquisition module. The corresponding pressure detection signal; the displacement detection device 130 is set correspondingly to the lifting actuator 111, and is used to measure the vertical movement displacement value of each cat claw and generate the corresponding displacement detection signal; the data acquisition module 140 is electrically connected to both the pressure detection device 120 and the displacement detection device 130, and is used to process and convert the received pressure detection signal and displacement detection signal to generate the corresponding digital signal; the controller 150 is electrically connected to the data acquisition module 140, and obtains the height pressure correlation of each cat claw according to the pressure value and displacement value obtained from the received digital signal, and calculates the target shim adjustment amount of each cat claw according to the pressure value or displacement value and the height pressure correlation. After the shims under each cat claw are adjusted by the target shim adjustment amount, the load difference of the lateral symmetrical position of the cat claw meets the preset standard. Meeting the preset standard means that the cylinder cat claw load distribution balance is achieved.

[0033] For example, please refer to Figure 2The cylinder cat claw load distribution device provided by this system includes a lifting device 110, a pressure detection device 120, a displacement detection device 130, a data acquisition module 140, and a controller 150. The lifting device is correspondingly positioned below each of the cat claws, and drives the corresponding cat claws to move vertically according to different driving forces provided by the power control module 112, causing each cat claw to generate different pressure and displacement values. The pressure detection device is mounted on the lifting execution module 111 to measure the pressure value during the movement of each cat claw by the lifting device 110 and generate a corresponding pressure detection signal. The displacement detection device measures the vertical displacement value of each cat claw and generates a corresponding detection signal. The data acquisition module is connected to... The system processes and converts the received pressure and displacement detection signals to generate corresponding digital signals. Based on the received pressure and displacement values, the controller obtains the height-pressure correlation of each cat paw and calculates the target shim adjustment amount for each cat paw based on the pressure, displacement, and height-pressure correlation. This replaces traditional manual load distribution, avoids measurement errors caused by manual measurement, and improves measurement accuracy. Furthermore, the controller can obtain the height-pressure correlation of each cat paw based on the digital signals from the data acquisition module and directly derive the target shim adjustment amount based on the pressure, displacement, and height-pressure correlation, avoiding multiple adjustments, improving the efficiency of cat paw load distribution, saving project time, and reducing economic costs.

[0034] For example, please refer to Figure 3 , Figure 3 This is a top view of the cylinder, where 210 represents the cat paw, including cat paws 211, 212, 213, and 214, and 220 represents the cylinder. In one embodiment, the cylinder cat paw load distribution device includes: a target shim adjustment amount in which the shim has a preset thickness, the preset thickness being a fixed value, including any value between 0.01mm and 0.07mm, such as 0.02mm, 0.03mm, 0.04mm, 0.05mm, etc.; a load difference at lateral symmetrical positions including a pressure difference at lateral symmetrical positions; and a preset standard including a pressure difference standard. Meeting the pressure difference standard means that the cat paw pressure load distribution is balanced. For example, the cat paw load difference at symmetrical positions satisfies the following formula:

[0035]

[0036] Wherein, Q1 is the pressure value detected by the pressure detection device under the cat paw 211, and Q2 is the pressure value detected by the pressure detection device under the cat paw 212.

[0037] The controller is configured to: derive the height-pressure correlation between each cat paw based on displacement and pressure values; iteratively calculate the pressure change under each cat paw based on the height-pressure correlation and the preset thickness of the shim; calculate the test pressure value based on the pressure change and the pressure value before adjustment; calculate the pressure difference at symmetrical positions based on the test pressure value; and output the target shim adjustment amount if the pressure difference at the lateral symmetrical positions meets the corresponding pressure difference standard. The displacement value can be set to vary by a preset value, ranging from 0mm to 1mm, for example, 0.1mm, 0.2mm, or 0.3mm. Simultaneously, the pressure change is measured to obtain the ratio of the displacement change to the pressure change, i.e., the height-pressure correlation. Based on the ratio of the preset thickness to the height-pressure correlation, the pressure change under the paddle can be calculated. The sum of the pressure change and the pressure before adjustment is the test pressure value. The pressure difference between the paddles at two symmetrical positions is calculated to determine if it meets the preset standard. Through iterative calculation, the target shim adjustment amount that meets the preset standard can be obtained, thus replacing manual adjustment, reducing reliance on manual labor in the work process, and saving adjustment time for paddle load distribution. It is also known that the smaller the preset shim thickness, the more balanced the paddle load of the cylinder after adjustment.

[0038] Please continue to refer to this. Figure 3 In one embodiment, the cylinder cat paw load distribution device includes: a lateral symmetrical position load difference including a lateral symmetrical position pressure difference; a preset standard including a pressure difference standard; and a controller configured to: calculate the target shim adjustment amount for each cat paw based on the original shim thickness and the height-pressure correlation; the original shim thickness is the shim thickness under the cat paw before adjustment. For example: obtaining the height-pressure correlation and the original shim thickness for cat paws 211 and 212 respectively, the target shim adjustment amount ΔH1 for cat paw 211 is calculated according to the following formula:

[0039]

[0040] Where Φ represents the height-pressure correlation, the first number of the double subscripts indicates the monitoring position, and the second number indicates the test position. For example, by using the lifting device below the cat paw 211 to drive the cat paw 211 vertically, the displacement and pressure values ​​of the cat paw 211 are measured. 11 This represents the ratio of the change in displacement value to the change in pressure value; the lifting device below the cat claw 211 drives the cat claw 211 to move vertically, and the displacement value and pressure value of the cat claw 212 are measured. Φ 21 This represents the ratio of the change in the displacement value to the change in the pressure value; H1 is the original thickness of the cat paw 211 gasket.

[0041] In this embodiment, the target pad adjustment amount can be calculated based on the original pad thickness, height pressure correlation, and formula, which shortens the calculation time, improves the working efficiency of cat paw load distribution, and improves the accuracy of the calculation results by obtaining the target pad adjustment amount for each cat paw according to the formula.

[0042] In one embodiment, the controller is configured to: acquire the ratio of the change in displacement value to the change in pressure value when each cat paw is driven by the corresponding lifting device to the same vertical displacement value, i.e., acquire the correspondence between the vertical displacement value of the cat paw and the corresponding pressure value; and / or acquire the ratio of the change in displacement value to the change in pressure value when each cat paw is driven by the corresponding lifting device to different vertical displacement values ​​with the same lifting pressure value, i.e., acquire the correspondence between the vertical displacement value of the cat paw and the corresponding pressure value. Establishing a height-pressure correlation using two different methods improves the flexibility of the cat paw load distribution device and avoids manual adjustment, saving manpower and resources.

[0043] Please refer to Figure 4 In one embodiment, the lifting device in the cylinder cat claw load distribution device includes a hydraulic lifting device, which is connected to a data acquisition module. For example, the hydraulic lifting device includes a lifting execution module 111 and a power control module 112. The lifting execution module can be a hydraulic jack or an air jack, and the power control module can be a corresponding hydraulic controller or pneumatic controller to provide driving force to the lifting execution module. At the same time, the power control module can also be equipped with a display screen to precisely control the driving force.

[0044] In one embodiment, the pressure detection device includes a pressure sensor connected to a data acquisition module. For example, the pressure sensor can be a capacitive pressure sensor, a strain gauge pressure sensor, a resistive pressure sensor, etc. For instance, a strain gauge can be installed between a cat's paw and a jack as a pressure detection device, which can improve measurement accuracy and can also be connected to a controller to detect and store changes in pressure values ​​in real time.

[0045] In one embodiment, the displacement detection device includes a displacement sensor connected to a data acquisition module. The displacement sensor is mounted on a dedicated bracket and does not directly contact the cylinder, thus improving measurement accuracy. For example, non-contact displacement sensors such as laser rangefinders, magnetostrictive sensors, and eddy current sensors can be used. For instance, an eddy current sensor can accurately measure the static and dynamic relative displacement changes between the metal object being measured and the sensor probe end face.

[0046] Please refer to Figure 4In one embodiment, the data acquisition module 140 includes an amplifier circuit 141 and an analog-to-digital converter circuit 142. The amplifier circuit 141, connected to the pressure detection device 120 and / or the displacement detection device 130, amplifies the received pressure detection signal and / or displacement detection signal, increasing the signal amplitude for subsequent data processing and output. For example, voltage amplifiers, current amplifiers, differential amplifiers, etc., can be used to amplify the pressure detection signal and / or displacement detection signal. The analog-to-digital converter circuit 142, connected to the amplifier circuit 141, converts the amplified analog signal of the pressure detection signal and / or displacement detection signal into a digital signal for subsequent controller processing. For example, a serial or parallel analog-to-digital converter can be used for conversion.

[0047] Based on the same inventive concept, this application also provides a cylinder cat's paw load distribution method for implementing the above-described cylinder cat's paw load distribution device. The solution provided by this method is similar to the solution described above; therefore, the specific limitations in one or more cylinder cat's paw load distribution method embodiments provided below can be found in the limitations of the cylinder cat's paw load distribution device described above, and will not be repeated here. Please refer to... Figure 4 and Figure 5 Cylinder cat's paw load distribution method, including:

[0048] Step S510: The lifting device 110, which is set up to correspond to multiple cat paws, drives the corresponding cat paws to move vertically;

[0049] Step S520: Measure the pressure value of each cat paw during the lifting device's movement based on the pressure detection device 120 installed on the lifting device 110, and generate a corresponding pressure detection signal;

[0050] Step S530: The vertical displacement value of each cat paw is measured by the displacement detection device 130 corresponding to the lifting device, and the corresponding displacement detection signal is generated.

[0051] Step S540: The data acquisition module 140 processes and converts the received pressure detection signal and displacement detection signal to generate the corresponding digital signal;

[0052] Step S550: Obtain pressure and displacement values ​​based on the received digital signals, obtain the height-pressure correlation of each cat paw, and calculate the target pad adjustment amount of the cat paw based on the height-pressure correlation. After the pads under each cat paw are adjusted by the target pad adjustment amount, the load difference of the lateral symmetrical position of each cat paw meets the preset standard.

[0053] In the above embodiments, the lifting device drives the corresponding cat claw to move vertically. Simultaneously, a pressure detection device measures the pressure value during the vertical movement of each cat claw, and a displacement detection device measures the displacement value during the vertical movement of each cat claw. A data acquisition module processes and converts the received pressure and displacement signals to generate corresponding digital signals, improving measurement accuracy and reducing measurement errors caused by manual labor and measuring tools. Based on the digital signals corresponding to the pressure and displacement values, a height-pressure correlation is obtained. Then, based on this correlation, the target shim adjustment amount for the cat claw is calculated, improving the working efficiency of the cylinder-cat claw load distribution, reducing the impact on the project schedule, and resulting in certain economic benefits.

[0054] As an example, the controller of the cylinder cat's paw load distribution device can also implement any of the traditional measurement methods, improving the flexibility of cylinder cat's paw load distribution and expanding application scenarios. For example, based on the hydraulic jacks simultaneously driving each cat's paw to move vertically, the verticality of the pressure sensor determines whether the design value of the cylinder cat's paw load distribution has been reached. When the pressure value reaches the design value, the controller outputs the change in displacement sensor value at this time, which is the target shim adjustment amount. The shims under each cat's paw are adjusted according to the target adjustment amount, thereby completing the load distribution of each cat's paw in one go, improving work efficiency. The design value of the cylinder cat's paw load distribution is related to the cylinder's own weight; for example, if the cylinder's own weight is N, the design value of the cylinder cat's paw load distribution is 0.25N.
