Description

Technical Field

[0001] This utility model relates to the field of ring-shaped utility pole technology, and in particular to a stress testing device for the steel-concrete connection node of a ring-shaped concrete utility pole. Background Technology

[0002] In power transmission and distribution systems, ring-shaped concrete poles serve as crucial infrastructure, and their performance and stability directly impact the safe operation of the power grid. The connection points between ring-shaped concrete poles and steel components are particularly critical, as they must withstand complex mechanical environments, including wind loads, conductor tension, and stress changes caused by temperature variations. However, traditional stress testing methods for the steel-concrete connection points of ring-shaped concrete poles largely rely on manual operation, which is not only inefficient but also struggles to guarantee accuracy and consistency. Furthermore, limited by testing methods and equipment, traditional methods often only detect the stress at specific locations or nodes, failing to achieve comprehensive testing across multiple locations and nodes. This, to some extent, restricts the accuracy and depth of the overall performance evaluation of ring-shaped concrete poles.

[0003] According to Chinese Publication No. CN220490528U, a device for testing the mechanical properties of a ring-shaped concrete pole relates to the field of mechanical property testing technology. It includes a first support and at least two second supports, both of which are rolling supports. The first support supports the tail end of the pole, and its top is rotatably connected to a support block via a ball bearing turntable. The second supports support the pole body and the area near the front end of the pole. Two sets of concrete cast-in-place piles are staggered on both sides of the tail end of the pole. The device also includes a testing assembly, which includes a winch and a displacement sensor. The winch is connected to a torque sensor, which is used to connect to the front end of the pole. The displacement sensor is connected to the front end of the pole. When a rotational torque is generated at the tail end of the pole, the rotation of the ball bearing turntable can eliminate the influence of the rotational torque. The first support supports the tail end of the pole, and the second supports support the pole body and the area near the front end of the pole, ensuring that the pole remains horizontal throughout the testing process.

[0004] The aforementioned patent documents and prior art have the following technical problems:

[0006] 2. When testing the stress nodes of a ring-shaped utility pole, traditional testing methods can only test specific locations or nodes on the surface of the ring-shaped concrete pole, and cannot achieve comprehensive testing of multiple locations and nodes. Utility Model Content

This achieves force detection at multiple positions and nodes, increases the detection range, and thus improves the accuracy and quality of the ring-shaped pole detection.

The top surface of the arc-shaped detection table 905 is provided with a mounting screw seat 904, which is threaded to the bottom end of the U-shaped connecting frame 903. The mounting screw seat 904 allows the arc-shaped detection table 905 and the U-shaped connecting frame 903 to be detachably installed and removed, facilitating maintenance and replacement. The first detection component 9 drives the U-shaped connecting frame 903 and the arc-shaped detection platform 905 to move through the guide base 901 and the first detection cylinder 902. The arc-shaped detection platform 905 contacts the top of the ring pole body 2 and applies force.

[0038] When inspecting the surface of the ring-shaped pole body 2, the inspection is mainly performed by applying force along the bottom surface of the ring-shaped pole body 2 using the second inspection component 10. Specifically, the second inspection component 10 includes a connecting base 1001 and a spherical inspection platform 1005.

[0039] During the control and use of the entire device, a main controller 7 is bolted to the front of the experimental base 1.

With precise control, the accuracy and reliability of experimental results are ensured. The guide hydraulic cylinders 5 connected to the clamping assembly 8 on the surface of the experimental base 1 are all located on one side, while the guide hydraulic cylinders 5 connected to the surfaces of the first detection assembly 9 and the second detection assembly 10 are located on the other side. This enables automatic detection and feedback of the node positions of the ring pole body 2, improving detection efficiency and accuracy. Through multi-position and multi-node force detection, the accuracy and quality of detection are improved.

[0041] Reference Figure 1-10 Based on the content of the above specific embodiments, the following content is further disclosed:

[0042] In practical use, the first detection component 9 and the second detection component 10 can be combined into a single detection component, such as... Figure 8 As shown, the first detection cylinder 902 is vertically bolted to the end of the connecting base 1001 of the first detection component 9 away from the spherical detection stage 1005. Then, a U-shaped connecting frame 903, a mounting screw seat 904, and an arc-shaped detection stage 905 are sequentially arranged. With this structure, Figure 10 As shown, it can realize alternating force detection at the same position on the surface of the ring pole body 2. Compared with the split design, it can realize the detection of the same position on the surface of the ring pole body 2 without adjusting the position, which facilitates the rapid detection of the surface of the ring pole body 2. The split structure or the combined structure can be selected for use according to the actual use requirements. Specific Implementation Example 3:

[0044] Reference Figure 1-10 Based on the content of the above specific embodiments, the following content is further disclosed:

[0045] The first detection contact 906 and the second detection contact 1006 are mainly used for force detection and deformation detection on the surface of the ring pole body 2, thereby realizing the test of the compressive strength of the surface of the ring pole body 2.

[0046] The connection between the first detection contact 906 and the second detection contact 1006 and the main controller 7 is usually made by transmitting electrical signals. Specifically, these two detection contacts are connected to corresponding sensors that can sense changes in force or deformation and convert them into electrical signals. These electrical signals are then transmitted to the main controller 7 via wires or wireless means, such as Bluetooth or Wi-Fi. However, considering the stability and reliability of the experimental environment, wired connection is usually preferred. The main controller 7 contains a data acquisition module that can receive and process these electrical signals and convert them into readable force or deformation data.

[0047] Sensor selection: For force detection, force sensors such as strain gauges and piezoelectric sensors can be used. These sensors can directly measure the force applied to them and convert it into an electrical signal. For deformation detection, strain gauges or similar deformation sensors can also be used. They can sense changes in the shape of an object and generate corresponding electrical signals.

[0048] The first detection contact 906 and the second detection contact 1006 are respectively installed on the bottom or top surface of the arc-shaped detection stage 905 and the spherical detection stage 1005. These contacts are tightly connected to the sensor to ensure accurate transmission of force or deformation information. The sensor is connected to the main controller 7 through a wire. The wire should have a certain degree of flexibility to adapt to movement and deformation during the detection process.

[0049] Signal transmission and processing: When the detection contact is subjected to force or deformation, the sensor generates a corresponding electrical signal. These signals are transmitted to the data acquisition module of the main controller 7 via wires. The data acquisition module performs preprocessing such as amplification and filtering on the received signals to improve the signal-to-noise ratio and accuracy. The preprocessed signals are converted into digital signals and stored in the memory of the main controller 7 for subsequent analysis and processing.

[0050] Feedback and display: The main controller 7 also includes a display module, such as an LCD screen or LED display screen, to display the detected force or deformation data in real time. Users can view the experimental data through the operation interface of the main controller 7 and make adjustments or records as needed.

[0051] The actual structure of the first detection contact 906 and the second detection contact 1006

[0052] Force sensor contact: For force sensors, the detection contact is usually a metal sheet or thin film that is in close contact with the sensor's sensitive element. When an external force is applied to the contact, it converts the force into an electrical signal through some means, such as strain or piezoelectric effect. The contact surface may be specially treated to improve its wear resistance, corrosion resistance, and conductivity.

[0053] Deformation sensor contacts: The structure of deformation sensor contacts is similar to that of force sensors, but they focus more on sensing changes in shape. They may contain sensitive elements such as tiny strain gauges or optical fibers, which can detect minute deformations and generate corresponding electrical signals. The contact surface between the contacts and the main body 2 of the annular rod should ensure good fit in order to accurately sense deformation.

[0054] Implementation: When designing the detection contacts, the shape, material, and stress characteristics of the ring-shaped pole body 2 need to be considered to ensure that the sensor can accurately sense the required force or deformation. The installation positions of the sensor and contacts should be precisely calculated and optimized to ensure that the key nodes and areas of the ring-shaped pole body 2 can be covered during the test. The performance parameters of the sensor and contacts, such as sensitivity, accuracy, and range, should be selected according to the experimental requirements to ensure the accuracy and reliability of the test results. During the experiment, the sensor and contacts need to be calibrated and maintained regularly to ensure their long-term stability and accuracy.
