Technical Field
[0001] This utility model relates to the field of testing fixtures, specifically to a submarine cable traction testing fixture. Background Technology
[0002] Submarine cables serve as carriers for generating or transmitting electricity in the ocean. Due to the influence of ocean currents and the requirements of cable laying, submarine cables must undergo sampling inspection after production and before leaving the factory, with a focus on checking their strength and toughness. In existing technology, submarine cables are tested for strength and toughness using traction testing fixtures. However, these fixtures typically fix one end of the submarine cable in a fixed position and then pull the other end. As the traction force increases, the submarine cable is stretched, thus testing its strength and toughness. However, this type of testing fixture yields results with significant errors and low accuracy. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a submarine cable traction testing fixture.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a submarine cable traction testing fixture, comprising: a first fixing member, a second fixing member, a first fixing connecting rod, a fixing connecting plate, a second fixing connecting rod, a connecting member, and a traction hook, wherein the first fixing member is provided with a first fixing conical through hole, the first fixing conical through hole penetrating the first fixing member, and one end of the cable to be tested is fixedly installed in the first fixing conical through hole; the second fixing member is provided with a second fixing conical through hole, the second fixing conical through hole penetrating the second fixing member, and the other end of the cable to be tested is fixedly installed in the second fixing conical through hole; the first fixing connecting rod and the first fixing member are fixedly connected together by bolts or screws, and the fixing connecting plate is fixedly installed on the first fixing connecting rod; the second fixing connecting rod and the second fixing member are fixedly connected together by bolts or screws, one end of the connecting member is fixedly connected to the second fixing connecting rod, and the traction hook is fixedly connected to the other end of the connecting member.
[0005] Furthermore, it also includes a preset number of intermediate components, which are disposed between the first fixing component and the second fixing component. Each intermediate component has a through hole that extends through the intermediate component. The cable under test passes through the through hole and its two ends are respectively fixedly installed in the first fixing tapered through hole on the first fixing component and the second fixing tapered through hole on the second fixing component.
[0006] Furthermore, it also includes a preset number of straightening members and a preset number of docking and fixing members. A first annular groove and a second annular groove are provided at both ends of the straightening member, and a through hole is provided in the middle. The through hole passes through the middle member, and the straightening member passes through the through hole, with both ends of the straightening member extending out of the through hole. One docking and fixing member is engaged with the first annular groove or the second annular groove of one straightening member, and another docking and fixing member is engaged with the second annular groove or the first annular groove of another adjacent straightening member. The two adjacent straightening members are fixed together by countersunk screws, thereby keeping the two adjacent straightening members relatively stationary.
[0007] Furthermore, the first fixing member is also provided with a third annular groove. The docking fixing member is engaged with the third annular groove on the first fixing member on one hand, and engaged with the first annular groove of the straightening member adjacent to the first fixing member on the other hand, thereby fixing the first fixing member and the straightening member adjacent to the first fixing member together.
[0008] Furthermore, the first fixed connecting rod includes a first segment and a second segment, the first segment and the second segment are fixedly connected together, and the second segment and the first fixing member are fixed together by bolts or screws, so that the first fixed connecting rod and the first fixing member are fixedly connected together; the first segment is provided with a snap-fit groove, and the fixed connecting plate is snapped into the snap-fit groove of the first segment, so that the fixed connecting plate and the first fixing member are fixedly installed together.
[0009] Furthermore, the second fixed connecting rod is provided with an internal cavity, from which a first boss and a second boss protrude laterally from the inner wall of the internal cavity. The first boss and the second boss are arranged opposite each other and there is a preset distance between them, so that there is space between the first boss and the second boss that allows the connector to pass through. The connector includes a connector body and a connecting protrusion. The connecting protrusion is disposed at the end of the connector or at a preset position. The connector body passes through the space between the first boss and the second boss, and the connecting protrusion abuts against the first boss and the second boss, thereby preventing the connector body from moving further, so that the connector and the second fixed connecting rod are connected together.
[0010] Furthermore, the main body of the connector and the traction hook are detachably fixed together by bolts, thereby fixing the connector and the traction hook together.
[0011] Furthermore, it also includes a stabilizing member, which is fixedly connected to the main body of the connector and the connecting member, and the stabilizing member abuts against the second fixed connecting rod, so that the connecting member will not move relative to the second fixed connecting rod when the connecting member and the second fixed connecting rod are connected together.
[0012] Furthermore, the connector body of the connector is provided with a snap-in groove, and the stabilizing member is provided with a snap-in protrusion. The snap-in protrusion snaps into the snap-in groove on the connector body, thereby fixing the stabilizing member and the connector body together.
[0013] The beneficial effects of this application are: the submarine cable traction test fixture provided by this application has a simple structure, is easy to install, and has high testing efficiency. Since it is equipped with a straightening member and an intermediate member, the weight of the cable under test is borne by the straightening member and the intermediate member after the cable under test is installed in the test fixture, which greatly reduces the error of part of the traction force "counteracting" the weight of the cable under test in the prior art, thereby making the test results more accurate and the error rate lower.
