Description

Technical Field

[0001] The present invention relates to a test bench system, and in particular to a cable stretching test bench system and a use method thereof. Background Art

[0002] The cable has the properties of tensile resistance, impact resistance, wear resistance, flexibility and lightness. In the past, steel cables, hemp or cotton ropes were commonly used. After the emergence of synthetic fibers, most of them were made of nylon, polypropylene, vinylon, polyester, etc. In addition to light specific gravity, high strength, good impact resistance and wear resistance, synthetic fiber cables also have the advantages of corrosion resistance, mildew resistance, and insect resistance. For example, the strength and wear resistance of nylon cables are several times higher than that of hemp and cotton cables, and the specific gravity of polypropylene cables is less than water, so they can float on the water surface, making them convenient and safe to operate. Chemical fiber cables are divided into two categories according to the processing structure: 3-strand, multi-strand twisted cables and 8-strand, multi-strand braided cables. The diameter of 3-strand cables is generally 4 to 50 mm, and the diameter of 8-strand cables is generally 35 to 120 mm. In addition to being used for ship mooring, chemical fiber cables are also widely used in transportation, industry, mining, sports, and fisheries. According to the needs of special purposes, metal materials can also be woven into the cable core.

[0003] In order to promote the development of transportation, industry, mining, sports and fisheries, and taking into account the impact of cables on these industries, the research and development of cable technology is an indispensable link in promoting the development and utilization of these industries.

[0004] Traditional cable tensioning test benches directly fix the cable on the tensioner, and the detector used can only detect the state of the cable at one point, so the detection data obtained in the cable tensioning test is not comprehensive. At the same time, there is the problem of frequently changing the position of the cable detector. Summary of the invention

[0005] In view of the problem that the cable tensioning test bench system has a single cable tensioning state and needs to frequently change the position of the cable detector, the present invention provides a cable tensioning test bench system and a method for using the same. The laser scanner cluster is used to quickly and accurately detect the state of the cable, and the movable design is adopted to enable the laser scanner to move freely on the slide rail, so as to perform a more comprehensive cable state detection.

[0006] The technical means adopted by the present invention are as follows:

[0007] A cable tensile test bench system, comprising:

[0008] A test bench frame, the test bench frame is used to fix the cable and apply tension to the cable;

[0009] A guide rail arranged parallel to the direction in which the cable extends;

[0010] A laser scanner frame arranged on the guide rail and capable of sliding along the guide rail, wherein at least one laser scanner is arranged in the laser scanner frame;

[0011] The two ends of the cable are respectively fixed on the experimental table frame and pass through the laser scanner frame to receive the laser emitted by the laser scanner.

[0012] Furthermore, the experimental bench frame includes a cable stretching track and a cable stretcher, and the cable stretcher slides along the cable stretching track to change the tension applied to the cable.

[0013] Furthermore, the cable tensioner comprises a sliding portion moving on the cable tensioning track and a cable eye for fixing the cable.

[0014] Furthermore, the laser scanner frame comprises a guide rail pulley, a drive motor and a drive shaft; the guide rail pulley is connected through the drive shaft and slides along the guide rail under the action of the drive motor;

[0015] A plurality of laser scanners are arranged inside the laser scanner frame. The laser scanners are arranged along the circumference of the cable, and the cable position irradiated by each laser scanner is the same.

[0016] The present invention also provides a method for using the above-mentioned cable stretching test bench system, comprising the following steps: connecting both ends of the cable to the cable eyelets and passing the cable through the laser scanner rack at the same time, stretching the cable by controlling the cable tensioner to move on the cable stretching track, detecting the state of the cable by the laser scanner cluster, and at the same time the laser scanner rack moves on the guide rail so that the laser scanner cluster can detect the state of the cable within a certain length.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The present invention is different from the traditional cable stretching test bench system in that it uses a guide rail structure, so that the laser scanner frame can move freely on the pulley, and the laser scanner cluster can scan the state of a section of cable.

[0019] 2. The present invention integrates three laser scanners into a cluster, which can detect the status of the cable more quickly and accurately.
