Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable tension testing device for cable processing. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. The installation environment of cables is usually in poor conditions such as high temperature and humidity. Therefore, in order to ensure the quality of the cables for long-term use, the performance of the cables often needs to be tested after processing.

The technical solution of the utility model can improve the efficiency of tension testing.

[0004] Although the above patent can improve the efficiency of tension testing, there are still some shortcomings. For example, the device can only perform relatively ideal linear tension on the cable in the vertical and horizontal directions. However, in reality, cables often need to be bent in places due to terrain problems, and the cables in the bent state will also form tension due to torque. However, the device does not have the ability to simulate the tension in this scenario. Therefore, it is necessary to propose a new type of cable tension testing device for cable processing. Utility Model Content

A rotatable fixed block is provided to solve the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cable tension test device for cable processing, comprising: a device body, an inner surface wall of the device body is movably inserted with a bidirectional threaded rod, an inner surface wall of the bidirectional threaded rod, an outer wall side of the device body is fixedly inserted with a first motor, and the output end of the first motor is fixedly connected to one end of the outer wall of the bidirectional threaded rod, two threaded outer surfaces of the bidirectional threaded rod are rotatably sleeved with a moving frame, the inner wall bottoms of the two moving frames are fixedly inserted with a first electric telescopic rod, and the outer walls of the two moving frames are opened with lifting grooves, The output ends of the two first electric telescopic rods are fixedly installed with lifting blocks, one side of the outer wall of the two lifting blocks is fixedly installed with side blocks, and the outer walls of the two side blocks are movably inserted in the inner walls of the two lifting grooves, and one side of the outer wall of the two side blocks is movably inserted with lower locking blocks, the tops of the two lower locking blocks are hinged with upper locking blocks, and the other sides of the two upper locking blocks are fixedly connected to the two lower locking blocks by bolt structures, and the inner walls of the two side blocks are fixedly inserted with second motors, and the output ends of the two second motors are fixedly connected to one end of the outer walls of the two lower locking blocks.

[0008] Preferably, a second electric telescopic rod is fixedly installed on the top of the two side blocks, and an insert block is fixedly installed on the output ends of the two second electric telescopic rods. The outer walls of the two locking blocks are provided with slots, and the inner walls of the two slots are matched with the outer walls of the two insert blocks respectively, so that when the torque test is not used, the locking block can be locked by inserting the insert block into the slot.

[0009] Preferably, a third motor is fixedly inserted on the top of the device body, a one-way threaded rod is movably inserted on the inner wall of the device body, and a lifting frame is rotatably sleeved on the outer wall of the one-way threaded rod to facilitate tension testing of the cable in the vertical direction.

At this time, the part at the center of the cable is also pulled due to the torque, thereby performing a second tension test on the cable. While the cable is undergoing a tension test, a torque test is also performed on the cable, further improving the performance of the test cable.

[0015] 2. In the utility model, by setting the plug block and the slot, when it is necessary to perform a tension test on the cable in a vertical state, the upper locking block and the lower locking block can be locked by the plug block and the slot to prevent the upper locking block and the lower locking block from rotating due to the lack of a locking mechanism when the cable is subjected to linear tension, thereby affecting the tension test.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 3 As shown, the utility model provides a cable tension test device for cable processing, comprising: a device body 1, an inner surface wall of the device body 1 is movably inserted with a bidirectional threaded rod 2, an inner surface wall of the bidirectional threaded rod 2, and an outer wall side of the device body 1 are fixedly inserted with a first motor 3, and the output end of the first motor 3 is fixedly connected to an outer wall end of the bidirectional threaded rod 2, two threaded outer surfaces of the bidirectional threaded rod 2 are rotatably sleeved with a moving frame 4, the inner wall bottoms of the two moving frames 4 are fixedly inserted with a first electric telescopic rod 5, the outer surfaces of the two moving frames 4 are opened with a lifting slot 6, and the two first electric telescopic rods 5 are fixedly inserted with a lifting slot 6. The output ends are fixedly installed with lifting blocks 7, one side of the outer walls of the two lifting blocks 7 is fixedly installed with side blocks 8, and the outer walls of the two side blocks 8 are movably inserted in the inner walls of the two lifting grooves 6, and one side of the outer walls of the two side blocks 8 is movably inserted with lower locking blocks 9, the tops of the two lower locking blocks 9 are hingedly installed with upper locking blocks 10, and the other sides of the two upper locking blocks 10 are fixedly connected to the two lower locking blocks 9 by bolt structures, and the inner walls of the two side blocks 8 are fixedly inserted with second motors 11, and the output ends of the two second motors 11 are fixedly connected to one end of the outer walls of the two lower locking blocks 9.

[0024] The effect achieved by the entire embodiment 1 is that, by setting the side blocks 8 and the second motor 11, the cable is inserted into the two lower locking blocks 9, and fixed by the upper locking block 10 and the bolt structure, the bidirectional threaded rod 2 can be started to perform a tension test in the vertical direction. After the test is completed, the second motor 11 can be started to rotate the two lower locking blocks 9. During the rotation, the fixed part of the cable will be rotated to generate torque to bend the cable. At this time, the part at the center of the cable is also pulled due to the generation of torque, thereby performing a second tension test on the cable. While the cable is undergoing a tension test, the cable is also subjected to a torque test, thereby further improving the performance of the test cable.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the inner surface walls of the two lower locking blocks 9 and the inner surface walls of the two upper locking blocks 10 are fixedly installed with rubber rings 12, the tops of the two side blocks 8 are fixedly installed with second electric telescopic rods 13, the output ends of the two second electric telescopic rods 13 are fixedly installed with plug blocks 14, the outer surface walls of the two upper locking blocks 10 are provided with slots 15, and the inner surface walls of the two slots 15 are matched with the outer surface walls of the two plug blocks 14 respectively, the top of the device body 1 is fixedly inserted with a third motor 16, the inner surface wall of the device body 1 is movably inserted with a one-way threaded rod 17, the outer surface wall of the one-way threaded rod 17 is rotatably sleeved with a lifting frame 18, the front surface of the lifting frame 18 is fixedly installed with a baffle 19 by snap-fitting, the outer surface wall of the lifting frame 18 is fixedly installed with a limit block 20, and the outer surface wall of the limit block 20 is movably inserted in the inner surface wall of the device body 1, the bottom of the inner wall of the device body 1 is provided with a slide groove 21, and the outer surfaces of the two movable frames 4 are movably inserted in the inner surface wall of the slide groove 21.

[0026] The effect achieved by the entire embodiment 2 is that, by setting the plug block 14 and the slot 15, when it is necessary to perform a vertical tension test on the cable, the upper locking block 10 and the lower locking block 9 can be locked by the plug block 14 and the slot 15 to prevent the upper locking block 10 and the lower locking block 9 from rotating due to the lack of a locking mechanism when the cable is subjected to a linear tension, thereby affecting the tension test. Then, a lifting frame 18 is set to facilitate the vertical testing of the cable, so as to further improve the stability of the tension test.

[0027] The working principle of the whole device is as follows: first start the first motor 3 to move the two moving frames 4 a short distance toward the center, then put the cables inside the two lower locking blocks 9 and inside the lifting frame 18, then fix the two upper locking blocks 10 on the top of the two lower locking blocks 9 by means of bolt structures, clamp the cables, and install the baffle 19 on the lifting frame 18, and start the second electric telescopic rod 13 to insert the two plug blocks 14 into the two slots 15, so that the two upper locking blocks 10 are locked, and the installation is completed;

[0028] When the cable needs to be pulled in the horizontal direction, it is only necessary to start the first motor 3 to move the two moving frames 4 away from each other to form the pulling force;

[0029] When the cable needs to be pulled in the vertical direction, the third motor 16 is started to drive the one-way threaded rod 17 to rotate, and the lifting frame 18 is moved up and down under the action of the limit block 20 to form an upward or downward thrust on the cable, so as to test the vertical tension;

[0030] When the tension generated by the torque needs to be tested, the second electric telescopic rod 13 is first started to remove the two plug blocks 14 from the slots 15, and the second motor 11 is started to drive the two lower locking blocks 9 to rotate. During the rotation process, the part where the cable is fixed will rotate with the rotation of the lower locking blocks 9, thereby generating a torque, forming a tensile force on the cable in the middle part, and then the test is performed;

[0031] Finally, the tension of the test cable when it forms a wave shape can be measured by extending one of the two first electric telescopic rods 5 upwards and contracting the other one downwards.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
