Description

Technical Field

[0001] The invention relates to the technical field of electric power pole detection, and in particular to a concrete pole deflection performance detection device and a detection method thereof. Background Art

[0002] The function of the concrete pole deflection performance detection device is to simulate the load conditions (such as wind force, gravity, etc.) that the pole may encounter in actual use by applying external force, and monitor the deformation of the pole in real time, especially the deflection change. This detection device is mainly used to evaluate the structural performance of the pole to ensure its stability and safety in long-term use. The structure of the concrete pole deflection performance detection device usually includes a traction force application device, a measurement system, a data acquisition and processing system, and a support and stabilization device. The traction force application device (such as a hydraulic jack, an electric winch, etc.) is used to simulate the external force and is applied to the end of the pole. The measurement system consists of a displacement sensor and a strain gauge to monitor the deformation of the pole in real time, especially the change in deflection. The data acquisition system transmits the sensor data to the computer and determines whether the pole exceeds the safety deflection standard through data analysis. In addition, the support device ensures the stability of the equipment to avoid deformation of the equipment itself during the test. The traction force causes the pole to produce elastic deformation. The detection device records the deflection change through the sensor, and calculates the deflection value of the pole in combination with the physical properties and mechanical model of the pole to determine the bearing capacity and structural health of the pole;

[0003] As disclosed in the authorization announcement number CN117871878B, the concrete pole inspection robot and inspection method include a visual perception unit for automatically identifying the appearance size of the concrete pole and autonomously determining the lifting point and sending it to the lifting unit; the lifting unit is used to lift the concrete pole to the test station based on the lifting point; the clamping unit is used to fix and clamp one end of the concrete pole; the tension testing unit is used to apply tension to the other end of the concrete pole to perform a tension test on the concrete pole; the visual perception unit is also used to inspect the appearance quality of the concrete pole at the test station; the information processing unit is respectively connected to the visual perception unit and the tension testing unit, and is used to determine the specifications and models based on the appearance size of the concrete pole, and match and associate them with the appearance quality and tension test results.

[0004] During use, the above technical solution mainly relies on the hoisting part to hoist the concrete pole to the test station. However, after the concrete pole located in the test station completes a tension deflection test, it is necessary to move the concrete pole axially to change the force point at the end of the concrete pole and retest it to meet the purpose of variable testing. At this time, the concrete pole located in the test station requires the staff to use external traction equipment to move it axially. In order to ensure the accuracy of the detection, each deflection test of the pole requires the traction force applied to be stable and uniform. However, the concrete pole is large in size and heavy in weight. When the pole moves axially, the force condition at the end of the pole will change due to the change in the traction force application point. If the force is uneven during the movement of the pole, or the pole itself undergoes irregular deformation during the movement, the deflection test data will be inaccurate, thereby affecting the reliability of the entire test result. Summary of the invention

[0005] The purpose of the present invention is to provide a concrete pole deflection performance detection device and a detection method thereof to solve the problems raised in the above background technology.

[0006] A device for detecting the deflection performance of a concrete pole, comprising: a long U-shaped base frame, an upper circular frame being fixed at the top of the long U-shaped base frame, and a front-type double-axis pole picking module for downward limiting the concrete pole is arranged on one side of the top of the upper circular frame, a Y-axis screw electric module 1 and a Y-axis screw electric module 2 in a mirror-symmetrical relationship are installed at the bottom of the long U-shaped base frame below the front-type double-axis pole picking module, a rear seat and a front seat are installed at the moving ends of the Y-axis screw electric module 1 and the Y-axis screw electric module 2 respectively, so as to limit the end of the concrete pole, and a front seat for carrying is arranged on the other side of the top of the upper circular frame A dual-axis traction mobile module is used to move the concrete pole close to or away from the front dual-axis pole picking module. The front dual-axis pole picking module and the dual-axis traction mobile module change the relative position relationship between the pole and the rear seat and the front seat. By adjusting the axial position of the pole, different load states of the pole in actual use are simulated. A digital micrometer B and a digital micrometer A are respectively installed on the outer walls on the opposite sides of the rear seat and the front seat. The digital micrometer B and the digital micrometer A are arranged in a diagonal structure. A clamp for installing the digital micrometer B and the digital micrometer A is provided on the outer walls on the opposite sides of the rear seat and the front seat.

[0007] A track frame, wherein the track frame is fixed on an outer wall of one side of a long U-shaped chassis, and a trolley is slidably installed on the top of the track frame, and a winch for applying tension to a concrete pole is installed at the bottom of the trolley, a displacement acquisition node C is installed on the other side of the bottom of the long U-shaped chassis, and a PLC control panel is installed on one side of the surface of the long U-shaped chassis, the output end of the PLC control panel is electrically connected to the input end of the winch, the front dual-axis picking rod module, the dual-axis traction moving module, the Y-axis screw electric module 1, and the Y-axis screw electric module 2, respectively, and the output ends of the digital micrometer A, the digital micrometer B, and the displacement acquisition node C are electrically connected to the input end of the PLC control panel.

[0008] A method for detecting the deflection performance of a concrete pole is implemented using the above-mentioned device for detecting the deflection performance of a concrete pole. The method comprises the following steps:

[0009] S101: Use an external lifting device to deliver the concrete pole to be inspected into the interior of the long U-shaped chassis, so that one end of the concrete pole is located between the rear seat and the front seat, and the other end is located on one side of the winch;

[0010] S102: Y-axis screw electric module 1 and Y-axis screw electric module 2 adjust the relative position and spacing between the rear seat and the front seat, that is, the rear seat and the front seat are close to or away from each other, so as to limit the position of the concrete pole later;

[0011] S103: applying a pulling force to the other end of the concrete pole by means of a winch, so that the concrete pole is deformed under the action of the external force. As the pulling force gradually increases, the pole will bend and the deflection will change. At this time, the digital micrometer A and the digital micrometer B will detect the deflection change of one end of the pole in real time, and the displacement acquisition node C will collect the displacement variable of the other end of the pole under the force state in real time;

[0012] S104: using a front-mounted dual-axis pole picking module and a dual-axis traction movement module to change the relative position relationship between the pole and the rear seat and the front seat, and simulating different load states of the pole in actual use by adjusting the axial position of the pole;

[0013] S105: By comparing the deflection changes at different positions of the pole, the structural stability of the pole can be evaluated to determine whether it meets the use standards. After the test is completed, stop applying the pulling force, and return the Y-axis screw electric module 1 and the Y-axis screw electric module 2 to the positions of the rear seat and the front seat to perform the lifting operation on the pole.

[0014] In the above-mentioned concrete pole deflection performance detection device and detection method, by setting a long U-shaped base frame, Y-axis screw electric module 1, Y-axis screw electric module 2, rear seat, and front seat, the Y-axis screw electric module 1 and the Y-axis screw electric module 2 make the rear seat and the front seat close to or far away from each other, so as to limit the end of the concrete pole, so as to make a reasonable configuration according to the actual size and requirements of the pole, and by setting a track frame, a trolley, and a winch tensile machine, the winch tensile machine applies a pulling force to the other end of the pole to cause it to deform. At this time, the digital micrometer A, the digital micrometer B, and the displacement acquisition node C detect the deformation of the pole, and the front dual-axis pole picking module and the dual-axis traction moving module are used to change the pole and the rear seat and the front seat. The position relationship is changed to change the test variables and test the deflection performance of the pole under different conditions. In this process, the front-type dual-axis pole picking module and dual-axis traction movement module can accurately control the change of the axial position of the pole during the test to ensure that the amplitude, speed and force state of each movement are within the preset range. Since the pushing and traction force are applied to the entire pole body during the movement, it is ensured that the pole is stable and the force is uniform during axial movement, avoiding accidents such as tilting and falling of the pole during the movement, and reducing unnecessary impact or irregular deformation of the pole during the position change. Under the premise of ensuring uniform force, multi-point testing is carried out between multiple force points to ensure that the test covers different parts of the pole and comprehensively evaluates its deflection performance.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Please also see Figures 1 to 4As shown, the concrete pole deflection performance detection device includes a long U-shaped base frame 1, an upper circular frame 2 is fixed to the top of the long U-shaped base frame 1, and a front double-axis pole picking module 6 for downward limiting the concrete pole is arranged on one side of the top of the upper circular frame 2, and a Y-axis screw rod electric module 1 101 and a Y-axis screw rod electric module 2 102 in a mirror-symmetrical relationship are installed at the bottom of the long U-shaped base frame 1 below the front double-axis pole picking module 6, and the moving ends of the Y-axis screw rod electric module 101 and the Y-axis screw rod electric module 2 102 are respectively installed with a rear seat 8 and a front seat 9 to limit the end of the concrete pole, and the other side of the top of the upper circular frame 2 is provided with a The dual-axis traction moving module 7 approaches or moves away from the front dual-axis picking-up module 6. The front dual-axis picking-up module 6 and the dual-axis traction moving module 7 change the relative position relationship between the concrete pole and the rear seat and the front seat. By adjusting the axial position of the concrete pole, different load states of the concrete pole in actual use are simulated. The outer walls on the opposite sides of the rear seat 8 and the front seat 9 are respectively installed with a digital micrometer B12 and a digital micrometer A11. The digital micrometer B12 and the digital micrometer A11 are arranged in a diagonal structure. The outer walls on the opposite sides of the rear seat 8 and the front seat 9 are provided with a clamp 10 for installing the digital micrometer B12 and the digital micrometer A11.

[0029] A track frame 3, the track frame 3 is fixed on an outer wall of one side of the long U-shaped chassis 1, and a trolley 4 is slidably installed on the top of the track frame 3, and a winch 5 for applying tension to the concrete pole is installed at the bottom of the trolley 4, a displacement acquisition node C13 is installed on the other side of the bottom of the long U-shaped chassis 1, and a PLC control panel 15 is installed on one side of the surface of the long U-shaped chassis 1, and the output end of the PLC control panel 15 is electrically connected to the input end of the winch 5, the front-type dual-axis pick-up module 6, the dual-axis traction movement module 7, the Y-axis screw electric module 1 101, and the Y-axis screw electric module 2 102, respectively, and the output end of the digital micrometer A11, the digital micrometer B12, and the displacement acquisition node C13 are electrically connected to the input end of the PLC control panel 15;

[0030] During the entire detection process, the PLC control panel 15 plays a role of coordination and automatic control. Through a preset program, the control panel can automatically adjust the operation of the Y-axis screw electric module 101 and the Y-axis screw electric module 2 102, and monitor the applied tension and deformation of the pole in real time. Through the PLC control panel 15, the operator can set different test parameters, such as the size and speed of the tension applied by the winch 5, to ensure that the test process meets the standard requirements.

[0031] A method for detecting the deflection performance of a concrete pole in this embodiment, such as the above-mentioned device for detecting the deflection performance of a concrete pole, comprises the following steps:

[0032] S101: Use external lifting equipment to deliver the concrete pole to be inspected into the long U-shaped chassis 1, so that one end of the concrete pole is located between the rear seat 8 and the front seat 9, and the other end is located on one side of the winch 5;

[0033] S102: The Y-axis screw electric module 101 and the Y-axis screw electric module 2 102 adjust the relative position and spacing between the rear seat 8 and the front seat 9, that is, the rear seat 8 and the front seat 9 are close to or away from each other, so as to limit the position of the concrete pole later;

[0034] S103: applying a pulling force to the other end of the concrete pole through the winch 5, so that the concrete pole is deformed under the action of the external force. As the pulling force gradually increases, the pole will bend and the deflection will change. At this time, the digital micrometer A11 and the digital micrometer B12 will detect the deflection change of one end of the pole in real time, and the displacement acquisition node C13 will collect the displacement variable of the other end of the pole under the force state in real time;

[0035] S104: using the front-mounted dual-axis pole picking module 6 and the dual-axis traction movement module 7 to change the relative position relationship between the pole and the rear seat 8 and the front seat 9, and simulating different load states of the pole in actual use by adjusting the axial position of the pole;

[0036] S105: By comparing the deflection changes at different positions of the pole, the structural stability of the pole can be evaluated to determine whether it meets the use standards. After the test is completed, the application of tension is stopped (for example, the winch 5 will stop applying tension), and the Y-axis screw electric module 101 and the Y-axis screw electric module 2 102 will also return the rear seat 8 and the front seat 9 to their original positions to perform the lifting operation on the pole.

[0037] During the deflection test, the tip deflection under the load of any level of winch is calculated according to the formula:

[0038] a si =a Ci -L1(a Ai +a Bi ) / L2+a Ai

[0039] Where: a si —When testing the deflection, the tip deflection value under the load of any level of winch, in millimeters (mm); a Ci —The deformation value of the tip under any level of winch load measured by the displacement acquisition node C, in millimeters (mm); a Ai —The deformation value at the measuring point A under the load of any level of winch measured by the digital micrometer A, in millimeters (mm); a Bi—The deformation value at the measuring point B under the load of any level of winch measured by the digital micrometer B, in millimeters (mm); L I —Total length of the pole, L I =L1+L2+L3, in millimeters (mm); L2—height of the pole support point, in millimeters (mm).

[0040] For further information, please also see Figure 5 and Figure 6 , four equidistant and mutually parallel square-mouth profiles are welded at the bottom of the long U-shaped chassis 1, and the extension direction of the square-mouth profiles is parallel to the extension direction of the track frame 3. The upper surfaces of the four square-mouth profiles are slidably mounted with supports 14 for supporting concrete poles, and the inside of the supports 14 is provided with a trapezoidal notch that is wide at the top and narrow at the bottom. If the pole to be tested for deflection is less than or equal to ten meters in length, one support 14 is preferably used; if the pole is longer than ten meters, two or more supports 14 are preferably used, and the supports 14 are used to prevent the influence of the deadweight deflection caused by the excessive length of the pole, so as to reduce the deflection influencing variables during the test;

[0041] When the staff adjusts the pulling force point of the winch 5 on the pole, the staff tightens the hook of the traction end of the winch 5 to the cable through the traction belt. At this time, the winch 5 continuously tightens the cable to cause the pole to bend and deform. A number of equally spaced support feet 301 are installed on the front and rear outer walls of the track frame 3, and a hollow positioning column 302 extending vertically upward is fixed to the top of the support foot 301. T-shaped pin rods 401 are threadedly installed at the corners of the bottom of the trolley 4. A square-mouthed connecting arm 303 is fixed on the outer wall of one side of the track frame 3 close to the long U-shaped chassis 1, and the end of the square-mouthed connecting arm 303 away from the track frame 3 is welded to the outer wall of one side of the long U-shaped chassis 1;

[0042] The staff manually pushes the trolley 4 to move in the extension direction of the track frame 3. After the position of the trolley 4 and the winch 5 is debugged, the staff screws the T-pin rod 401 downward until the T-pin rod 401 is screwed into the corresponding hollow positioning column 302, and uses four pairs of one-to-one corresponding T-pin rods 401 and hollow positioning columns 302 to lock the position of the trolley 4 and the winch 5 to ensure the stability of the winch 5 during the traction action.

[0043] For further information, please also see Figure 7 and Figure 8The double-axis traction moving module 7 includes a slide plate 701 slidably mounted on the top of the upper circular frame 2, a screw lifting unit 707 mounted on the top of the slide plate 701, a lower support platform 704 mounted on the moving end of the screw lifting unit 707, a two-way screw pulling unit 705 mounted on the lower surface of the lower support platform 704, and a double-layer arc-shaped arm 706 mounted on the two moving ends of the two-way screw pulling unit 705. The double-axis traction moving module 7 also includes a gear rotating unit 702 mounted on the outer wall of one side of the slide plate 701 and two parallel linear racks 703 fixed on the top of the upper circular frame 2. The gear rotating unit 702 is mounted on the outer wall of one side of the slide plate 701 and two parallel linear racks 703 fixed on the top of the upper circular frame 2. The rotating unit 702 includes a double-axis motor installed on the outer wall of one side of the slide plate 701 and a driving gear installed on the two output shafts of the double-axis motor. The driving gear and the linear rack 703 are meshed with each other. The structural parts of the front-type double-axis picking-up module 6 and the double-axis traction moving module 7 are consistent. The difference between the two is that the slide plate 701 in the front-type double-axis picking-up module 6 is fixed to the top of the upper circular frame 2 and does not have the ability to move in the X-axis. The bidirectional screw rod pulling unit 705 in the front-type double-axis picking-up module 6 makes the double-layer arc-shaped arm 706 close to the outer wall of the pole without exerting pressure on the outer wall of the pole.

[0044] When a deflection test is completed and the position between the pole end and the rear seat 8 and the front seat 9 needs to be changed, the staff turns on the Y-axis screw electric module 1 101 and the Y-axis screw electric module 2 102 through the PLC control panel 15, and the Y-axis screw electric module 101 and the Y-axis screw electric module 2 102 move the rear seat 8, the front seat 9 and the digital micrometer A11 and the digital micrometer B12 away from each other, so that enough space is reserved between the rear seat 8 and the front seat 9 for the front-type dual-axis pick-up module 6 to move;

[0045] The screw lifting unit 707 includes a nut pair 7072 fixed at the center of the top of the slide 701, a threaded shaft 7074 installed inside the nut pair 7072, and a guide column 7075 fixed at the corner position inside the slide 701, the top of the four guide columns 7075 is fixed with an upper connecting plate 7073, the lower support platform 704 is fixed to the bottom of the four guide columns 7075, the top of the threaded shaft 7074 is rotatably connected to the bottom end of the upper connecting plate 7073, the bottom end of the threaded shaft 7074 is rotatably connected to the top of the lower support platform 704, and a belt driving mechanism 7071 for driving the nut pair 7072 to rotate is installed at the top of the slide 701, and the belt driving mechanism 7071 includes a servo motor and a belt transmission structure installed at the output end of the servo motor;

[0046] The screw lifting unit 707 in the double-axis traction moving module 7 starts to work, and the screw lifting unit 707 drives the lower support platform 704, the double-layer arc-shaped arm 706 and other components to move downward until the arc mouth of the double-layer arc-shaped arm 706 is located on the outer wall side of the pole and the pole is clamped. At this time, the screw lifting unit 707 makes the lower support platform 704, the two-way screw pulling unit 705, the double-layer arc-shaped arm 706, and the pole move up a distance to facilitate the subsequent X-axis movement;

[0047] When the double-axis traction moving module 7 grabs the pole body, the gear rotation unit 702 and the linear rack 703 cooperate to make the slide plate 701, the two-way screw rod pulling unit 705, the double-layer arc-shaped arm 706 and other structures move in the X-axis extension direction of the upper circular frame 2. At this time, the gear rotation unit 702 drives the slide plate 701 to approach the front double-axis picking up module 6, so that the end of the pole is dislocated with the rear seat 8 and the front seat 9, and then the pole is located at the test starting position of the digital micrometer A11 and the digital micrometer B12. After the adjustment is completed, the double-axis traction moving module 7 actively puts down the pole. The axial movement function formed by the double-axis traction moving module 7 can not only accurately control the position of the pole, but also flexibly adjust the changes in the force points and test parameters according to the specifications, models and material properties of different poles. This flexibility and adaptability make the system not only suitable for a single model of pole, but also can meet the deflection detection needs of different types of poles.

[0048] For further information, please also see Fig. 9 , Fig.10 and Fig.11 , the displacement acquisition node C13 is located below the two double-layer arc-shaped arms 706, and the displacement acquisition node C13 includes a bottom plate 1301 slidably mounted on the bottom of the long U-shaped chassis 1, a control box 1302 mounted on the upper surface of the bottom plate 1301, and a double-axis debugging fixture mounted on the upper surface of the bottom plate 1301, and a pull-wire displacement sensor 1306 is installed on the mobile end of the double-axis debugging fixture, and the output end of the pull-wire displacement sensor 1306 is electrically connected to the input end of the control box 1302, and the output end of the control box 1302 is electrically connected to the input end of the PLC control panel 15, and the control box 1302 adopts a microcomputer control board and is connected to the pull-wire displacement sensor 1306 through a data line;

[0049] The dual-axis debugging fixture includes a column 1303 fixed on the top of the base plate 1301, a bolt seat 1304 slidably installed on one end of the surface of the column 1303, and a sliding column 1307 slidably installed inside the bolt seat 1304. The end of the sliding column 1307 away from the control box 1302 is fixed to the machine base 1305, the pull-wire displacement sensor 1306 is fixed to one side outer wall of the machine base 1305, and a locking pin 1308 for tightening the sliding column 1307 is installed on one side outer wall of the bolt seat 1304. The extension line of the central axis of the column 1303 is perpendicular to the extension line of the central axis of the sliding column 1307. The length of the column 1303 and the sliding column 1307 is 30 cm to 60 cm. The column 1303 and the sliding column 1307 are all made of stainless steel. When the pole is located in the long U-shaped chassis 1 and the debugging is completed, the staff manually slides the base plate 1 301, so that the bottom plate 1301 moves in the X-axis direction of the long U-shaped chassis 1, and manually adjusts the height of the bolt seat 1304 on the column 1303, and adjusts the position between the wire displacement sensor 1306 and the outer wall of the pole. At this time, the sliding column 1307 can be manually slid, so that the sliding column 1307 drives the machine base 1305 and the wire displacement sensor 1306 to move in the Y-axis direction until the zero point position of the wire displacement sensor 1306 is calibrated with the outer wall of the pole, and then the locking pin 1308 is used to lock the sliding column 1307 and the bolt seat 1304. When the end of the pole is moved by the winch 5, the pull rope of the wire displacement sensor 1306 is pulled out to drive the wheel to rotate, and the wheel drives the encoder to rotate at the same time, so that the wire displacement sensor 1306 obtains a distance signal, which is the displacement of the end of the pole;

[0050] The clamp 10 uses the column 1303, bolt seat 1304, machine base 1305, sliding column 1307, and locking pin 1308 in the displacement acquisition node C13, and uses the clamp 10 to adjust the positions of the digital micrometer A11 and the digital micrometer B12 on the Z axis and the Y axis to ensure that the digital micrometer A11 and the digital micrometer B12 are in contact with the outer wall of the pole for subsequent detection steps.

[0051] When the embodiment of the present application is in use, the staff first prepares the concrete pole required for inspection, and uses an external lifting device to deliver the concrete pole into the interior of the long U-shaped chassis 1, so that one end of the concrete pole is located between the rear seat 8 and the front seat 9, and the other end is located on one side of the winch 5. The staff then turns on the Y-axis screw electric module 101 and the Y-axis screw electric module 2 102 through the PLC control panel 15 to work. The Y-axis screw electric module 101 and the Y-axis screw electric module 2 102 realize the precise movement of the rear seat 8 and the front seat 9 in the Y-axis direction. The main purpose is to adjust the relative position and spacing between the rear seat 8 and the front seat 9, that is, the rear seat 8 and the front seat 9 are close to or away from each other, so as to facilitate the subsequent adjustment of the concrete pole. Limit, the ends of the concrete poles located inside the back seat 8 and the front seat 9 use digital micrometer A11 and digital micrometer B12 to detect the displacement of the poles during loading. To ensure that the micrometers can accurately contact the outer wall of the poles, use the clamp 10 to install the digital micrometer A11 and the digital micrometer B12 on the front seat 9 and the back seat 8 respectively, and ensure that their measuring probes are in close contact with the surface of the concrete pole at the calibrated zero position. During this process, the displacement acquisition node C13 is also debugged synchronously. It performs detection at the other end of the pole, and can collect real-time displacement data of the pole end located at the winch 5, and transmit the data to the PLC control panel 15. After the preparation is completed, external force is applied. At this stage, the winch 5 is the actuator, which is installed on the trolley 4. The staff can adjust the position of the trolley 4 and the winch 5 on the track frame 3 to adjust the tension application point of the winch 5 on the pole. The pole is deformed under the action of external force by applying tension through the winch 5. As the tension gradually increases, the pole will undergo a certain degree of bending and deflection change. At this time, the digital micrometer A11 and the digital micrometer B12 will detect the deflection change at one end of the pole in real time, and the displacement acquisition node C13 will collect the displacement variable of the other end of the pole under stress in real time. Through the display data of the digital micrometer A11 and the digital micrometer B12 and the collection data of the displacement acquisition node C13, the change trend of the pole deformation variable can be intuitively observed. In order to test the deflection of different pole starting positions, the front dual-axis pole picking module 6 and the dual-axis traction moving module 7 are used to change the relative position relationship between the pole and the rear seat 8 and the front seat 9, which is helpful to detect the deflection of the pole at different starting positions. By adjusting the axial position of the pole, the different load states of the pole in actual use are simulated to obtain more comprehensive deflection data. When the tension is gradually applied and the pole is deformed, the digital micrometer A11, the digital micrometer B12 and the displacement acquisition node C13 will feedback the deformation amount at both ends of the pole in real time. According to these data, the PLC control panel 15 can accurately analyze the deflection of the pole and output the corresponding test results. By comparing the deflection changes at different positions of the pole,It can evaluate the structural stability of the pole and determine whether it meets the use standards. After the test is completed, the system will stop applying tension, and the Y-axis screw electric module 101 and the Y-axis screw electric module 2 102 will also return the positions of the rear seat 8 and the front seat 9 to ensure that the equipment is in a safe state so as to perform the lifting operation on the pole.
