Abstract
Description
Technical Field
[0001] This utility model relates to the field of umbilical cable tensile testing technology, specifically to an umbilical cable terminal tensile testing device. Background Technology
[0002] In deep-sea oil and gas extraction, umbilical cables are used to transmit power, signals, and various media. As an important component of the underwater production system, the umbilical cable connects to the control unit on the production platform at the upper end and to the seabed terminal at the lower end, transmitting control signals from the upper platform to various underwater functional components. The underwater umbilical cable terminal is a key accessory of the umbilical cable, and the umbilical cable terminal tensile testing device is a professional equipment used to test the connection strength and reliability of the umbilical cable terminal.
[0003] However, existing technologies still have many shortcomings in practical use. For example, if it is inconvenient to conduct tensile tests on the umbilical cable, the breakage of the umbilical cable will make it impossible to recover the valuable underwater equipment, resulting in huge economic losses. At the same time, in the tensile test of the umbilical cable, if the cable body cannot be clamped tightly, the umbilical cable may slip in the clamp, which will directly affect the accuracy of the test data, cause the test to fail, and may even cause safety risks and equipment damage.
[0004] To address the aforementioned problems, the inventors have proposed an umbilical cable terminal tensile testing device. Utility Model Content
[0005] To address the problems of inconvenience in performing tensile tests on umbilical cables and the inability to clamp umbilical cables, the purpose of this utility model is to provide a tensile testing device for umbilical cable terminals.
[0006] To solve the above technical problems, the present invention adopts the following technical solution: an umbilical cable terminal tensile testing device, including a platform, a tensioning device fixedly connected to the top surface of the platform, the tensioning device including a fixed shell, the bottom surface of the fixed shell being fixedly connected to the platform, a bidirectional threaded rod rotatably connected between the inner walls of the two sides of the fixed shell, a motor fixedly connected to one side of the fixed shell, the output end of the motor extending into the fixed shell and fixedly connected to the bidirectional threaded rod, two sliding plates threaded onto the outer surface of the bidirectional threaded rod, and a clamping device provided on the upper part of the sliding plates.
[0007] As a preferred technical solution of this application, the clamping device includes symmetrically distributed lead screws, the outer surface of the lead screws being threadedly connected to the slide plate, one end of the lead screw being fixedly connected to a rotating plate, the other end of the lead screw being rotatably connected to a clamping frame, a plurality of rubber pads being fixedly connected to the inner wall of one side of the clamping frame, and a through groove being provided on the upper part of the slide plate.
[0008] Through the above technical solution, rotating the rotating plate drives the lead screw to rotate. Since the lead screw is threadedly connected to the slide plate, the rotation of the lead screw is converted into the horizontal movement of the clamping frame. The clamping frame is located in the through groove, which provides movement space for the clamping frame, ensuring that it can move along a path perpendicular to the stretching direction. By pushing it to move through the lead screw, the umbilical cable is squeezed between the rubber pads. By rotating the lead screw, the rubber pads increase the friction, preventing the umbilical cable from slipping during the test and avoiding hard damage to the cable body. The distance between the clamping frame and the slide plate can be adjusted to effectively clamp the umbilical cable.
[0009] As a preferred technical solution of this application, a display screen is fixedly connected to one side of the tabletop, and multiple buttons are fixedly connected to the lower part of the tabletop.
[0010] Using the above technical solution, the display screen and buttons work together to perform a tensile test.
[0011] As a preferred technical solution of this application, two guide rods are fixedly connected between the inner walls of the two sides of the fixed shell, and the outer surface of the guide rods is movably sleeved with the lower part of the slide plate.
[0012] Through the above technical solution, the guide rod plays a guiding role.
[0013] As a preferred technical solution of this application, the lower part of the slide plate is symmetrically fixedly connected with two sliders, and the inner walls on both sides of the fixed shell are provided with grooves for use with the sliders.
[0014] The above technical solution allows the slider to slide within the groove, further enhancing the stability of the skateboard during movement and preventing it from shifting or wobbling.
[0015] As a preferred technical solution of this application, the two slide plates are respectively threaded onto the opposite thread directions engraved on the outer surface of the bidirectional threaded rod.
[0016] Using the above technical solution, the two slides will move in opposite directions along the bidirectional threaded rod.
[0017] As a preferred technical solution of this application, the clamping frame is located in the through groove.
[0018] Through the above technical solution, the through groove provides movement space for the clamping frame, ensuring that it can move along a path perpendicular to the stretching direction.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. This utility model allows two sliding plates to move in opposite directions along a bidirectional threaded rod. The inner walls on both sides of the fixed shell are provided with grooves for use with the sliding blocks. The sliding blocks slide in the grooves to prevent them from shifting or shaking. The two sliding plates will move further and further apart, thereby achieving the purpose of effectively testing the tensile strength of the umbilical cable.
[0021] 2. This utility model can be moved by a lead screw to squeeze the umbilical cable between rubber pads. By rotating the lead screw, the rubber pads increase friction, preventing the umbilical cable from slipping during the test and avoiding hard damage to the cable body. The distance between the clamping frame and the sliding plate can be adjusted, thereby achieving the purpose of effectively clamping the umbilical cable. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.
[0030] Example: Figure 1-5 As shown, this utility model provides a tensile testing device for umbilical cable terminals, including a table 1, a display screen 4 fixedly connected to one side of the table 1, multiple buttons 5 fixedly connected to the lower part of the table 1, and a tensioning device 2 fixedly connected to the top surface of the table 1.
[0031] The stretching device 2 includes a fixed shell 21, the bottom surface of which is fixedly connected to the platform 1. A bidirectional threaded rod 22 is rotatably connected between the inner walls of the two sides of the fixed shell 21. A motor 23 is fixedly connected to one side of the fixed shell 21. The output end of the motor 23 extends into the fixed shell 21 and is fixedly connected to the bidirectional threaded rod 22. Two sliding plates 25 are threadedly fitted onto the outer surface of the bidirectional threaded rod 22. Two guide rods 24 are fixedly connected between the inner walls of the two sides of the fixed shell 21. The outer surface of the guide rods 24 is movably fitted onto the lower part of the sliding plates 25. The two sliding plates 25 are threadedly fitted onto the opposite thread directions engraved on the outer surface of the bidirectional threaded rod 22. Two sliders 26 are symmetrically fixedly connected to the lower part of the sliding plates 25. Slide grooves 27 for use with the sliders 26 are opened on both inner walls of the fixed shell 21. A clamping device 3 is provided on the upper part of the sliding plates 25.
[0032] The two slide plates 25 will move in opposite directions along the bidirectional threaded rod 22, and the slider 26 will slide in the groove 27, which further enhances the stability of the slide plates 25 when they move and prevents them from deviating and shaking. The two slide plates 25 will move further and further apart, which can effectively test the tensile strength of the umbilical cable.
[0033] The clamping device 3 includes symmetrically distributed lead screws 31. The outer surface of the lead screws 31 is threadedly connected to the slide plate 25. One end of the lead screws 31 is fixedly connected to a rotating plate 32, and the other end of the lead screws 31 is rotatably connected to a clamping frame 33. Multiple rubber pads 34 are fixedly connected to one inner wall of the clamping frame 33. A through groove 35 is opened on the upper part of the slide plate 25, and the clamping frame 33 is located in the through groove 35.
[0034] The lead screw 31 pushes it to move, squeezing the umbilical cable between the rubber pads 34. By rotating the lead screw 31, the distance between the clamping frame 33 and the slide plate 25 can be adjusted, which can effectively clamp the umbilical cable.
[0035] The working principle of the umbilical cable terminal tensile testing device in this application embodiment is as follows: rotating the rotating plate 32 drives the lead screw 31 to rotate. Since the lead screw 31 is threadedly connected to the slide plate 25, the rotation of the lead screw 31 is converted into the horizontal movement of the clamping frame 33. The clamping frame 33 is located in the through groove 35, which provides movement space for the clamping frame 33, ensuring that it can move along a path perpendicular to the tensile direction. By pushing it to move through the lead screw 31, the umbilical cable is squeezed between the rubber pads 34. By rotating the lead screw 31, the rubber pads 34 increase the friction, preventing the umbilical cable from slipping during the test and avoiding hard damage to the cable body. The distance between the clamping frame 33 and the slide plate 25 can be adjusted, thereby achieving the purpose of effectively clamping the umbilical cable.
[0036] After the motor 23 starts, its output end transmits power to the bidirectional threaded rod 22 inside the fixed shell 21, causing the bidirectional threaded rod 22 to rotate between the two inner walls of the fixed shell 21. The two slide plates 25 will move in opposite directions along the bidirectional threaded rod 22. In order to ensure the stability and straightness of the movement of the slide plates 25, two guide rods 24 are fixedly connected between the two inner walls of the fixed shell 21. The lower part of the slide plate 25 is movably sleeved on the outer surface of the guide rods 24, and the guide rods 24 play a guiding role. Two sliders 26 are symmetrically fixedly connected to the lower part of the slide plate 25. The inner walls of both sides of the fixed shell 21 are provided with grooves 27 for use with the sliders 26. The sliders 26 slide in the grooves 27, which further enhances the stability of the slide plate 25 when it moves and prevents it from deviating or shaking. The two slide plates 25 will move further and further apart, thereby achieving the purpose of effectively testing the tensile strength of the umbilical cable.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
