Wire tension testing device

Abstract

This utility model belongs to the field of wire tension testing, specifically a wire tension testing device. It includes a base plate, with a wire pulling mechanism on one side of the base plate (two mechanisms are provided). A measuring mechanism is fixedly connected to one side of the base plate. The wire pulling mechanism includes a mounting frame, one side of which is fixedly connected to one side of the base plate. This utility model works by winding a wire onto a set of wire pulling mechanisms, then pulling one end of the wire through a moving block and two sets of second tension rollers, winding it onto the wire pulling rollers, and then passing the other end of the wire through a hollow groove and pulling it between two mounting grooves. A clamping plate is used to fix the wire. A second motor drives a threaded rod to rotate, which in turn moves the moving block and the first tension roller. As the first tension roller moves, it pulls the fixed wire, and the tension of this section of wire is measured by a tension sensor. This eliminates the need for manual straightening and fixing of the wire, reducing measurement errors.

Description

Technical Field

[0001] This utility model relates to the field of wire tension testing, specifically a wire tension testing device. Background Technology

[0002] Guy wires are a common structural support and stabilization device in the engineering field, widely used in construction, power, communications, transportation and other industries. In the construction field, guy wires are often used to reinforce scaffolding, temporary support structures or stabilize heavy equipment such as tower cranes. They transmit tension through taut ropes or steel cables to enhance the stability of the overall structure. In the power and communications industries, guy wires are used to fix facilities such as utility poles and towers to ensure that the lines remain vertical and stable under severe weather or external forces, avoiding the risk of collapse or breakage. Guy wires are usually made of high-strength materials, such as steel wire ropes and synthetic fiber ropes, and have the characteristics of tensile strength, corrosion resistance and durability.

[0003] In existing technologies, the tension of the guy wire, as a key component for structural support and stability, directly affects the safety and stability of the overall structure. To ensure that the tension of the guy wire is within the design range and to avoid risks such as structural loosening or deformation and breakage due to insufficient tension, the guy wire is usually subjected to tension testing after production. However, when testing the tension of the guy wire, it is usually done manually to straighten and fix it, which cannot ensure that the straightening state of each section of the guy wire is consistent, resulting in errors in tension measurement and thus affecting the test results. Utility Model Content

[0004] To address the shortcomings of existing technologies, when testing the tension of a tension wire, it is usually done manually by pulling and fixing it. This cannot ensure that the tension of each section of the wire is consistent, leading to errors in tension measurement and affecting the test results. This invention proposes a tension wire testing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tension testing device for a pull wire, including a base plate, a pull wire mechanism is provided on one side of the base plate, two pull wire mechanisms are provided, and a measuring mechanism is fixedly connected to one side of the base plate;

[0006] The wire pulling mechanism includes a mounting frame, one side of which is fixedly connected to one side of the base plate. A frustum is rotatably connected to the inner cavity of the mounting frame. A wire pulling roller is fixedly connected to one side of the frustum. A fixing block is fixedly connected to one side of the wire pulling roller. Hollow grooves are formed on the surfaces of both the wire pulling roller and the fixing block. An installation groove is formed on the surface of the fixing block. There are two installation grooves. A retaining plate is movably inserted into the inner cavity of the installation groove.

[0007] Preferably, the measuring mechanism includes a support plate, and two support plates are provided. One side of the support plate is fixedly connected to one side of the base plate. A threaded rod is rotatably connected to the inner cavity of the support plate. A moving block is threadedly connected to the surface of the threaded rod. A first tension roller is fixedly connected to one side of the moving block. A tension sensor is fixedly connected to one side of the moving block. One side of the tension sensor is fixedly connected to the surface of the first tension roller.

[0008] Preferably, a connecting column is fixedly connected to one side of the base plate, and a second tension roller is fixedly connected to one side of the connecting column.

[0009] Preferably, a first motor is fixedly connected to one side of the base plate, and the output shaft of the first motor is fixedly connected to one side of the frustum.

[0010] Preferably, a fixing plate is fixedly connected to one side of the support plate, and a second motor is fixedly connected to one side of the fixing plate. The output shaft of the second motor is fixedly connected to one side of the threaded rod.

[0011] Preferably, a rubber ring block is fixedly connected to the inner cavity of the mounting groove, and an arc-shaped hook is fixedly connected to one side of the fixing block.

[0012] Preferably, a hollow block is fixedly connected to one side of the base plate, a long rod is fixedly connected to the inner cavity of the hollow block, a limit block is slidably connected to the surface of the long rod, and one side of the limit block is fixedly connected to one side of the moving block.

[0013] The advantages of this utility model are:

[0014] This invention solves the problem of manually straightening and fixing the wire by pulling it onto a set of wire-pulling mechanisms. One end of the wire is pulled through a moving block and two sets of second tension rollers, then wound onto the wire-pulling rollers. The other end is then passed through a hollow groove and pulled to the middle of two mounting slots, where a clamping plate secures the wire. Finally, one end of the wire is knotted and looped onto an arc-shaped hook. A second motor is then started to rotate a threaded rod, which in turn moves the moving block and the first tension roller. As the first tension roller moves, it pulls the fixed wire, allowing the tension of that section of wire to be measured by a tension sensor. This eliminates the need for manual straightening and fixing of the wire, reducing measurement errors and improving efficiency. It solves the problem that when testing the tension of a wire, manual straightening and fixing is often necessary, which cannot ensure consistent straightening of each section, leading to measurement errors and affecting the test results.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a wire tension testing device. (Refer to...) Figure 1-5The tension testing device includes a base plate 1, on one side of which a tension mechanism 2 is provided. There are two tension mechanisms 2. A measuring mechanism 3 is fixedly connected to one side of the base plate 1. The base plate 1 can be used to install the tension mechanism 2 and the measuring mechanism 3, so that they can be stably supported, thereby facilitating subsequent operation. The tension mechanism 2 is provided in two sets, located on both sides of the measuring mechanism 3. One set can be used to wind and fix one end of the tension mechanism, and the other set can be used to fix the other end of the tension mechanism. It can also wind up the measured portion of the tension mechanism, thereby eliminating the need for manual straightening and fixing of the tension mechanism. The measuring mechanism 3 can be used to measure the tension of the tension mechanism after it has been straightened by the tension mechanism 2, thereby assisting the tension mechanism 2 in completing the tension test, reducing measurement errors, and improving measurement accuracy.

[0025] The wire pulling mechanism 2 includes a mounting frame 201. One side of the mounting frame 201 is fixedly connected to one side of the base plate 1. A frustum 202 is rotatably connected to the inner cavity of the mounting frame 201. A wire pulling roller 203 is fixedly connected to one side of the frustum 202. A fixing block 204 is fixedly connected to one side of the wire pulling roller 203. Hollow grooves 205 are opened on the surfaces of both the wire pulling roller 203 and the fixing block 204. An installation groove 206 is opened on the surface of the fixing block 204. There are two installation grooves 206. A retaining plate 207 is movably inserted into the inner cavity of the installation groove 206.

[0026] Mounting bracket 201 is located on the upper part of base plate 1 and can be used to mount frustum 202, providing some support for frustum 202. Frustum 202 can support pull roller 203, allowing pull roller 203 to be stable on its upper part. Pull roller 203 can be used to wind up and store the measured pull wire, reducing the workload of workers, and at the same time assisting in fixing and straightening one end of the pull wire. Fixing block 204 is located on the upper part of pull roller 203 and can be used to assist in fixing one end of the pull wire, and at the same time facilitates the subsequent installation of clamping plate 207. Hollow grooves 205 are formed on one side of the pull roller 203 and the fixing block 204. They can be used to place the pull wire and assist in fixing the pull wire. There are two mounting grooves 206, which can be used to install clamping plates 207. The clamping plates 207 can be movably inserted into the inner cavity of the two mounting grooves 206 to fix and straighten one end of the pull wire, thereby eliminating the need for manual straightening of the pull wire. This facilitates subsequent tension measurement of the pull wire, ensures that the straightening state of the pull wire is consistent, and thus reduces measurement error and improves measurement accuracy.

[0027] Reference Figure 1 and Figure 2The measuring mechanism 3 includes a support plate 301, of which two support plates 301 are provided. One side of the support plate 301 is fixedly connected to one side of the base plate 1. A threaded rod 302 is rotatably connected to the inner cavity of the support plate 301. A moving block 303 is threadedly connected to the surface of the threaded rod 302. A first tension roller 304 is fixedly connected to one side of the moving block 303. A tension sensor 305 is fixedly connected to one side of the moving block 303. One side of the tension sensor 305 is fixedly connected to the surface of the first tension roller 304. The support plate 301 can be used to install the threaded rod 302, facilitating the rotation of the threaded rod 302 within its inner cavity. The rotation of the threaded rod 302 can drive the moving block 303 to move, thereby assisting in the subsequent tension measurement of the pull wire. The moving block 303 can be used to install the first tension roller 304 and provide some support for the first tension roller 304. The first tension roller 304 can be used to assist the tension sensor 305 in testing the tension of the pull wire, thereby realizing the measurement of the pull wire. The tension sensor 305 is installed on one side of the first tension roller 304 and can measure the tension of the pull wire through the first tension roller 304, thereby assisting the pull wire mechanism 2 to complete automatic measurement, reducing the workload of the staff and improving the measurement efficiency.

[0028] Reference Figure 1 A connecting column 4 is fixedly connected to one side of the base plate 1, and a second tension roller 5 is fixedly connected to one side of the connecting column 4. The connecting column 4 can be used to support the second tension roller 5, so that the second tension roller 5 is fixedly installed on the upper part of the base plate 1. The second tension roller 5 can be used to assist the first tension roller 304 and the tension sensor 305 in measurement. The connecting column 4 and the second tension roller 5 are arranged in a group, located on both sides of the measuring mechanism 3. The operator can pass the pull wire around one group of second tension rollers 5 and then around the first tension roller 304 and another group of second tension rollers 5, thereby realizing the measurement of the tension of the pull wire and improving the convenience of measurement.

[0029] Reference Figure 2 and Figure 4 A first motor 6 is fixedly connected to one side of the base plate 1. The output shaft of the first motor 6 is fixedly connected to one side of the frustum 202. The first motor 6 can serve as the driving source for the rotation of the frustum 202. By driving the frustum 202 to rotate, the first motor 6 can drive other components in the wire pulling mechanism 2 to rotate, thereby winding up the wire after measurement, reducing the workload of the staff and improving the measurement efficiency.

[0030] Reference Figure 2A fixing plate 7 is fixedly connected to one side of the support plate 301, and a second motor 8 is fixedly connected to one side of the fixing plate 7. The output shaft of the second motor 8 is fixedly connected to one side of the threaded rod 302. The fixing plate 7 can be used to support the second motor 8, thereby installing the second motor 8 on one side of the support plate 301. The second motor 8 can be used as a drive source for the rotation of the threaded rod 302, thereby driving the measuring mechanism 3 to operate and assisting the measuring mechanism 3 in measuring the tension of the straightened wire.

[0031] Reference Figure 5 A rubber ring block 9 is fixedly connected to the inner cavity of the mounting groove 206, and an arc hook 10 is fixedly connected to one side of the fixing block 204. The rubber ring block 9 can be used to increase the friction of the clamping plate 207 installed in the inner cavity of the mounting groove 206, thereby improving the stability of the clamping plate 207 in fixing one end of the pull wire. The arc hook 10 can be used to assist the mounting groove 206 and the clamping plate 207 in further fixing one end of the pull wire, thereby improving the accuracy of subsequent measurement of the pull wire.

[0032] Reference Figure 1 A hollow block 11 is fixedly connected to one side of the base plate 1. A long rod 12 is fixedly connected to the inner cavity of the hollow block 11. A limit block 13 is slidably connected to the surface of the long rod 12. One side of the limit block 13 is fixedly connected to one side of the moving block 303. Two sets of hollow blocks 11, long rods 12, and limit blocks 13 are provided on both sides of the moving block 303. They can be used to limit the rotation direction of the moving block 303, preventing the threaded rod 302 from moving the moving block 303 while also causing the moving block 303 to rotate.

[0033] Working principle: When using this device, the operator can first wind the pull wire to be tested onto the pull wire mechanism 2. Then, the other end of the pull wire can be pulled through the moving block 303 and the two sets of second tension rollers 5, and then one end of the pull wire is wound onto the pull wire roller 203. The other end of the pull wire is then passed through the hollow groove 205 and pulled to the middle of the two mounting grooves 206. The clamping plate 207 is then used to install the device in the inner cavity of the mounting groove 206. Finally, one end of the pull wire is knotted, looped, and attached to the arc hook 10. The tension is fixed, eliminating the need for manual straightening of the tension line and reducing errors in subsequent tension measurement. Then, the second motor 8 can be activated to rotate the threaded rod 302. When the threaded rod 302 rotates, it moves the moving block 303 and the first tension roller 304 together. At this time, the movement of the first tension roller 304 pulls the fixed tension line, thereby measuring the tension of this fixed section of the tension line through the tension sensor 305. This allows for the measurement of the tension of the tension line segment. After completion, the end of the pull wire fixed by the clamping plate 207 and the arc hook 10 can be loosened. Then, the first motor 6 can drive the frustum 202, the pull roller 203, and the fixing block 204 to rotate, thereby winding up the measured pull wire segment. The clamping plate 207 and the arc hook 10 are used to fix one end of the pull wire again. The tension of the other end of the pull wire segment can be measured again by the measuring mechanism 3, thereby improving measurement efficiency and reducing the workload of the staff. That is, by using two sets of pull wire mechanisms 2 and the arc hook 10 to fix both ends of the pull wire, the measuring mechanism 3 can measure the tension of the pull wire segments fixed by the two sets of pull wire mechanisms 2, thereby eliminating the need for manual straightening and fixing of the pull wire, ensuring that the state of each pull wire segment is the same, thereby reducing measurement error and improving measurement efficiency. This solves the problem that when testing the tension of the pull wire, it is usually necessary to manually straighten and fix it, which cannot ensure that the straightening state of each pull wire segment is consistent, resulting in errors in tension measurement and affecting the test results.
