Description

Technical Field

[0001] This utility model relates to the field of tapered cement pole testing technology, specifically a device for testing the tensile strength of tapered cement poles. Background Technology

[0002] Conical concrete poles, also known as conical reinforced concrete poles, are pole-shaped building components with a conical cross-section. Their core structure consists of a steel reinforcement cage and poured concrete, offering high strength, corrosion resistance, and a long service life. They are widely used in power, telecommunications, and transportation sectors, primarily for erecting high-voltage or low-voltage power lines, installing communication base station antennas, and supporting traffic lights and monitoring equipment. Their tapered design, gradually tapering from top to bottom, ensures load-bearing capacity while reducing weight, facilitating transportation and on-site installation.

[0003] The existing Chinese patent announcement number CN220040000U, entitled "A Device for Testing the Tensile Strength of a Conical Cement Pole," explicitly states in its abstract that "This utility model discloses a device for testing the tensile strength of a conical cement pole, including a support base. A protective shell is welded to the top surface of the support base, and a top plate is fixedly installed at the top of the protective shell. A telescopic device is fixedly installed on the top surface of the top plate, and the output end of the telescopic device extends into the protective shell where a movable plate is installed. Limiting posts are fixedly installed at the four corners inside the protective shell. In this utility model, by setting up a protective shell, during the tensile strength testing of the conical cement pole, the protective shell can protect and collect the concrete debris that splashes when the conical cement pole splits, preventing the debris from causing harm to the workers. Furthermore, the coordinated use of the movable post, limiting block, buffer plate, buffer pad, and buffer spring can buffer and reduce noise from the splashed debris, preventing noise from the debris colliding with the protective shell and extending the service life of the protective shell."

[0004] However, in the existing technology, the installation position of the ultrasonic probe assembly is fixed, and it can only be tested at the same fixed position of the concrete core sample. It cannot flexibly cover different areas of the core sample. The concrete density and steel reinforcement distribution may vary at different positions of the conical cement rod. The test results at a single position are difficult to fully reflect the overall tensile strength. Furthermore, because the ultrasonic probe assembly is fixed in position, the tensile force can only be applied to the concrete core sample and monitored in a fixed direction during testing. It is impossible to adjust the tensile force direction and monitoring position according to the testing requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a device for testing the tensile strength of a tapered cement pole, in order to solve the problems mentioned in the background art, such as the inability to flexibly cover different areas of the core sample and the inability to adjust the direction of the tensile force and the monitoring position according to the testing requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A device for testing the tensile strength of a tapered cement pole includes a mounting box, and a testing component is installed inside the mounting box. The detection assembly includes a mounting ring, mounting rails are provided on both sides of the mounting box, a rotating ring is rotatably provided inside the mounting ring, and an ultrasonic probe assembly is provided on one side inside the rotating ring.

[0007] In a preferred embodiment of this utility model, a placement groove is provided at the rear of the mounting box, and the mounting ring is slidably connected to the mounting rail.

[0008] In a preferred embodiment of this utility model, threaded openings are provided on both sides of the mounting ring, and a threaded rod is rotatably provided inside the mounting rail, with the threaded rod and the threaded openings being threadedly connected.

[0009] In a preferred embodiment of this utility model, a timing pulley is provided behind the threaded rod, and the timing pulleys on both sides are engaged by a timing belt.

[0010] In a preferred embodiment of this utility model, a first motor is provided on one side of the rear of the mounting box, and the output end of the first motor is connected to a threaded rod on one side.

[0011] In a preferred embodiment of this utility model, a second motor is provided behind the top of the mounting ring, and a drive gear is provided on the output end of the second motor.

[0012] In a preferred embodiment of this utility model, a driven gear is provided on the outer side of the rotating ring, and the driving gear meshes with the driven gear.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: The tensile strength of concrete core samples is tested using an ultrasonic probe assembly. During the test, a first motor drives a threaded rod to rotate, which, through a synchronous pulley and belt, causes both threaded rods to rotate simultaneously. This threaded transmission causes the mounting ring to move the ultrasonic probe assembly back and forth, allowing for testing at different locations on the concrete core sample. A second motor drives a drive gear to rotate, which in turn rotates a rotating ring, moving the ultrasonic probe assembly to different positions. This allows for tensile strength testing of the concrete core sample from various locations, not just a single position.

[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses a device for testing the tensile strength of a conical cement rod, comprising an installation box 1, which is an installation structure used for installing the overall structure. The installation box 1 contains a testing component for testing the tensile strength of the conical cement rod. A placement groove 11 is provided at the rear of the installation box 1. When it is necessary to test the tensile strength of a concrete core sample in the conical cement rod, the concrete core sample is first processed to make both ends of the core sample flat. The conical concrete core sample is then inserted into the placement groove 11 from the rear. The diameter of the placement groove 11 is designed according to the diameter of the produced conical concrete core sample so that it fits snugly into the core.

[0020] The testing component includes a mounting ring 2, mounting rails 12 on both sides of the mounting box 1, a rotating ring 22 inside the mounting ring 2, and an ultrasonic probe assembly 3 on one side inside the rotating ring 22. The ultrasonic probe assembly 3 adopts the ultrasonic probe assembly in the background technology patent and is used to observe the degree of splitting of the concrete core sample, thereby determining its tensile strength. That is, the tensile strength of the concrete core sample is detected by the ultrasonic probe assembly 3. The mounting ring 2 is slidably connected to the mounting rail 12. Threaded openings 21 are provided on both sides of the mounting ring 2. A threaded rod 13 is rotatably provided inside the mounting rail 12. The threaded rod 13 is threadedly connected to the threaded openings 21. A synchronous pulley 14 is provided behind the threaded rod 13. The synchronous pulleys 14 on both sides are engaged by a synchronous belt. A first motor 23 is provided on one side of the rear of the mounting box 1. The first motor 23 is a servo motor with a built-in electromagnetic braking structure. The specific model can be Panasonic A6 series MHMD082P1U. The output end of the first motor 23 is connected to one side of the threaded rod 13. When testing the tensile strength of the concrete core sample, the first motor 23 can drive the threaded rod 13 to rotate. Through the synchronous pulley 14 and synchronous belt, the threaded rods 13 on both sides can rotate simultaneously. Through the threaded transmission, the mounting ring 2 can drive the ultrasonic probe assembly 3 to move back and forth, thereby detecting different positions of the concrete core sample. The rotating ring 22 is rotatably installed inside the mounting ring 2. A second motor 31 is located at the top rear of the mounting ring 2. The second motor 31 is a servo motor with a built-in electromagnetic brake structure. The specific model can be Mitsubishi MR-J4 series HG-KR053. A drive gear 32 is provided on the output end of the second motor 31, and a driven gear 33 is provided on the outside of the rotating ring 22. The drive gear 32 and the driven gear 33 mesh, that is, the second motor 31 drives the drive gear 32 to rotate. Through gear transmission, the rotating ring 22 rotates, and drives the ultrasonic probe assembly 3 to rotate to different positions. Thus, the concrete core sample can be pulled in different positions for tensile strength testing, and it is not limited to the same position. All precision structures such as the threaded rod 13, the threaded end 21, and the gears can be made of high-strength metal materials to ensure service life. A PLC controller is provided on the top of the mounting box 1. The model can be Siemens S7-200 SMART series CPU SR40, which is used to control all electrical equipment in the device. This is a conventional technical means for those skilled in the art.

[0021] The working principle of this utility model is as follows: When it is necessary to test the tensile strength of a concrete core sample in a conical cement rod, the concrete core sample is first processed to make both ends of the core sample flat for easy testing. The conical concrete core sample is inserted into the placement groove 11 from the rear. When the conical concrete core sample is pulled from the outside, the tensile strength of the concrete core sample is detected by the ultrasonic probe assembly 3. When testing the tensile strength of the concrete core sample, the first motor 23 drives the threaded rod 13 to rotate. Through the synchronous pulley 14 and synchronous belt, the threaded rods 13 on both sides rotate simultaneously. Through the threaded transmission, the mounting ring 2 drives the ultrasonic probe assembly 3 to move back and forth, thereby detecting different positions of the concrete core sample. The second motor 31 drives the drive gear 32 to rotate. Through the gear transmission, the rotating ring 22 rotates and drives the ultrasonic probe assembly 3 to rotate to different positions. Thus, the tensile strength of the concrete core sample can be tested from different positions, not limited to the same position.
