Description

Technical Field

[0001] The invention belongs to the technical field of cable tension testing, in particular to a cable tension testing instrument. Background Art

[0002] Cable is a general term for wires and cables, which are usually used to transmit electrical energy, signals or realize electromagnetic energy conversion. They are made of one or more mutually insulated conductors and an outer insulating protective layer to transmit electricity or information from one place to another. During the production process of cables, in order to ensure the quality of cables during the process of being put into use, it is necessary to conduct random inspections on the cables during the production process and test the tensile performance of the cables.

[0003] The patent with announcement number CN220772802U discloses a horizontal cable tension test device, which relates to the field of cable tension test technology, including a test bench, a support leg is provided at the bottom of the test bench, a fixed shielding cover is fixedly connected to the top of the test bench, a movable shielding cover is provided at one end of the fixed shielding cover, a first clamping mechanism is installed at the top of the test bench at one end of the fixed shielding cover away from the movable shielding cover, an L-shaped movable plate is movably connected to the top of the test bench at one end of the movable shielding cover, a second clamping mechanism is installed on the movable plate, a tension sensor is installed on one side of the movable plate, and the movable plate is pulled by a pulling mechanism. The horizontal cable tension test device can shield the cable under test during the cable tension test to prevent the cable from being broken and the broken debris from splashing out, thereby preventing the debris from affecting the tester.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although a shielding cover is provided to shield the cable under test to prevent debris from splashing when the cable breaks, since the diameter of the shielding cover is fixed, when the cable diameter is smaller than the diameter of the shielding cover, there is more redundant space between the cable and the shielding cover, and cable debris may still splash out from the opening of the shielding cover, affecting the testers, and the splashed debris is relatively scattered and difficult to clean. In addition, when the cable breaks, due to the large redundant space between the cable and the shielding cover, the cable may pop out of the shielding cover in a relatively bent state, and then become entangled with surrounding components, making it difficult to remove. In addition, when the cable breaks, the debris will adhere to the inner wall of the shielding cover. During subsequent use, the debris may fall onto the surface of the cable, affecting the surface quality of the cable.

[0047] Specifically, cables are a general term for wires and cables, which are usually used to transmit electrical energy, signals or realize electromagnetic energy conversion. They are made of one or more mutually insulated conductors and an outer insulating protective layer to transmit electricity or information from one place to another. In the production process of cables, in order to ensure the quality of cables during use, it is necessary to conduct random inspections on the cables during the production process and test the tensile performance of the cables. In the use of existing cable tension test devices, in order to avoid the flying debris when the cable is broken and affect the tester, a shielding cover will be set to However, since the shielding cover has a fixed diameter, when the cable diameter is smaller than the shielding cover diameter, there is more redundant space between the cable and the shielding cover, and the cable debris may still splash out from the opening of the shielding cover, affecting the tester, and the splashed debris is relatively scattered and difficult to clean up. In addition, when the cable is broken, the cable may pop out of the shielding cover and get entangled with surrounding parts, which is difficult to remove. In addition, when the cable is broken, the debris will adhere to the inner wall of the shielding cover. In subsequent use, the debris may fall onto the cable surface, affecting the surface quality of the cable;

[0048] Therefore, when the present embodiment is in use, after both ends of the cable are clamped by the clamping blocks 33, the cable passes through the telescopic hose 3, the motor 4 30 is started to drive the gear 29 to rotate, and the gear 29 drives the inclined groove plate 23 to rotate, so that the multiple guide pillars 28 can be moved at the same time, and the adjusting rod 24 slides on the fixed plate 20, so that the multiple pressing plates 1 25 move radially and approach the telescopic hose 3 to squeeze the tube openings on both sides of the telescopic hose 3, and when the pressing plate 1 25 moves, the pressing plate 2 26 and the pressing plate 3 27 slide relative to each other, and the tube opening of the telescopic hose 3 can be squeezed around the tube opening of the telescopic hose 3 under the cooperation of the pressing plates 1 25, 26 and 3 27, so that the tube opening of the telescopic hose 3 can be reduced to reduce the redundant space between the tube opening of the telescopic hose 3 and the cable, and then the motor 1 5 is started to drive the threaded rod 6 to rotate, so that the lifting plate 7 rises, so that the cable and the telescopic hose 3 can be stretched, and the tension sensor 36 is used to detect the tension;

[0049] When the cable breaks, the debris will be intercepted by the telescopic hose 3. In addition, since the redundant space between the tube opening of the telescopic hose 3 and the cable is small, the debris will also be intercepted at the tube opening. Even if debris splashes out through the tube opening, the amount is small, which is convenient for subsequent cleaning.

[0050] This avoids the situation in which a large amount of debris splashes out from the tube opening of the telescopic hose 3 when the cable breaks due to the redundant space between the cable and the telescopic hose 3 during the test, thus affecting the tester. Moreover, even if debris splashes out from the tube opening, the amount is small, which is convenient for cleaning.

[0051] When the cable is broken, the cable is removed. At this time, there are still debris attached to the inner wall of the telescopic hose 3. By driving the lifting plate 7 to rise to the highest point, at this time, the striking rod 12 is just between the two inclined groove plates 23, and then the motor 2 8 and the motor 3 14 are started at the same time. The motor 2 8 drives the gear 1 9 to rotate, and the arc-shaped slider 10 can make a circular motion under the cooperation of the gear ring 2. At the same time, the motor 3 14 drives the crank 15 to rotate, and the slider 17 can make a circular motion, so that the slide groove rod 16 and the frame 13 slide back and forth horizontally, and the striking rod 12 is used to knock the telescopic hose 3 around, and a collection container is set at the bottom of the telescopic hose 3. The debris shaken off by the knocking of the striking rod 12 will fall into the collection container;

[0052] Thus, by striking the telescopic hose 3 all around, the debris remaining on the inner wall of the telescopic hose 3 falls off, thereby achieving self-cleaning of the inner wall of the telescopic hose 3, and preventing the debris from falling onto the cable surface during subsequent use, thereby affecting the surface quality of the cable.

[0053] Therefore, by using the adjustable constriction-type covering mechanism, the tube mouth of the telescopic hose 3 can be squeezed around the tube mouth of the telescopic hose 3 under the cooperation of the pressure plate 1 25, the pressure plate 2 26, and the pressure plate 3 27, so that the tube mouth of the telescopic hose 3 can be reduced, thereby reducing the redundant space between the tube mouth of the telescopic hose 3 and the cable. When the cable is broken, the debris will be intercepted by the telescopic hose 3, and since the redundant space between the tube mouth of the telescopic hose 3 and the cable is small, the tube mouth will also intercept the debris, even if there is debris splashing out through the tube mouth, the amount is small, which is convenient for subsequent cleaning, and since the redundant space between the tube mouth and the cable is small, when the cable pops out from the tube mouth, the tube mouth will limit the activity range of the cable, thereby avoiding the cable popping out from the tube mouth in a relatively bent state and then getting entangled with surrounding components, and after the cable is broken, the telescopic hose 3 can be struck around the tube mouth to make the debris remaining on the inner wall of the telescopic hose 3 fall off, thereby realizing self-cleaning of the inner wall of the telescopic hose 3, thereby avoiding the situation that the debris falls on the cable surface during subsequent use and affects the surface quality of the cable.

[0054] Working principle: Place the two ends of the cable to be tested for tension between the two clamping blocks 33 on the upper and lower sides respectively, then start the motor 5 34 to drive the bidirectional threaded rod 35 to rotate, so that the two clamping blocks 33 on the front and rear sides can move simultaneously and approach each other, clamping the two ends of the cable so that the cable can be fixed, thereby ensuring the stability of the cable during the tension test. After the two ends of the cable are clamped by the clamping blocks 33, the cable passes through the telescopic hose 3, and the motor 4 30 is started to drive the gear 29 to rotate, and the gear 29 drives the inclined slot disk 23 to rotate, so that multiple guide columns 28 can be moved simultaneously, and the adjustment rod 24 is on the fixed disk 20. The plurality of pressing plates 1 25 are moved radially and approach the telescopic hose 3 to squeeze the tube openings on both sides of the telescopic hose 3. When the pressing plate 1 25 moves, the pressing plate 2 26 and the pressing plate 3 27 slide relative to each other. The tube opening of the telescopic hose 3 can be squeezed around the tube opening of the telescopic hose 3 under the cooperation of the pressing plates 1 25, 26 and 3 27, so that the tube opening of the telescopic hose 3 can be reduced to reduce the redundant space between the tube opening of the telescopic hose 3 and the cable. Then, the motor 1 5 is started to drive the threaded rod 6 to rotate, so that the lifting plate 7 rises, so that the cable and the telescopic hose 3 can be stretched, and the tension sensor 36 is used to detect the tension. When the cable breaks, the debris will be intercepted by the telescopic hose 3, and since there is little redundant space between the tube opening of the telescopic hose 3 and the cable, the tube opening will also intercept the debris, and even if there is debris splashing out through the tube opening, the amount is small, which is convenient for subsequent cleaning; thereby avoiding the situation in which, during the test process, there is a lot of redundant space between the cable and the telescopic hose 3, and when the cable breaks, a large amount of debris splashes out through the tube opening of the telescopic hose 3, causing an impact on the test personnel, and even if there is debris splashing out through the tube opening, the amount is small, which is convenient for cleaning; when the cable breaks, the cable is removed, and at this time, there is still debris attached to the inner wall of the telescopic hose 3 The lifting plate 7 is driven to rise to the highest point. At this time, the striking rod 12 is just between the two inclined groove plates 23. Then the motor 2 8 and the motor 3 14 are started at the same time. The motor 2 8 drives the gear 1 9 to rotate. Under the cooperation of the gear ring 2, the arc-shaped slider 10 can make a circular motion. At the same time, the motor 3 14 drives the crank 15 to rotate, so that the slider 17 can make a circular motion, so that the slide groove rod 16 and the frame 13 slide back and forth horizontally. The striking rod 12 is used to knock the telescopic hose 3 around one circle, and a collection container is set at the bottom of the telescopic hose 3. The debris shaken off by the striking rod 12 will fall into the collection container;

[0055] The telescopic hose 3 is struck all around to make the debris remaining on the inner wall of the telescopic hose 3 fall off, thereby realizing the self-cleaning of the inner wall of the telescopic hose 3 and avoiding the debris falling onto the cable surface and affecting the surface quality of the cable during subsequent use; the adjustable constriction-mouth covering mechanism can be used to squeeze the tube mouth of the telescopic hose 3 all around with the cooperation of the pressing plate 1 25, the pressing plate 2 26 and the pressing plate 3 27, so that the tube mouth of the telescopic hose 3 can be reduced, thereby reducing the redundant space between the tube mouth of the telescopic hose 3 and the cable. When the cable is broken, the debris will be intercepted by the telescopic hose 3, and because the tube mouth of the telescopic hose 3 and the redundant space between the cable and the cable are The space between the pipe opening and the cable is small, so the pipe opening will intercept the debris. Even if there is debris splashing out through the pipe opening, the amount is small, which is convenient for subsequent cleaning. In addition, since the redundant space between the pipe opening and the cable is small, when the cable pops out from the pipe opening, the pipe opening will limit the range of movement of the cable, avoiding the cable popping out from the pipe opening in a relatively bent state and then getting entangled with surrounding components. In addition, after the cable breaks, the telescopic hose 3 can be struck all around to make the debris remaining on the inner wall of the telescopic hose 3 fall off, thereby realizing self-cleaning of the inner wall of the telescopic hose 3 and avoiding the situation in which the debris falls on the cable surface and affects the surface quality of the cable during subsequent use.
