Description

Technical Field

[0001] The present invention relates to the field of cable detection, and in particular to a towing cable toughness adaptive detection device. Background Art

[0002] When dragging cables, they are subject to pulling, friction, collision and other effects, which test various indicators of the cables themselves, such as strength, toughness, and wear resistance. Therefore, all cables produced must be tested.

[0003] The existing cable testing equipment fixes the cable to be tested in a manner that vertical pressure is applied to both ends of the cable toward the cable axis to tighten and fix the cable. During the testing process, when other external forces are applied to the cable for testing, in order to ensure the stability of the cable, strong vertical pressure is applied to the fixing point. Excessive pressure causes deformation of the cable fixing point or even damage to the cable, and the integrity of the cable cannot be guaranteed.

[0004] The existing detection method deforms the cable through physical external forces such as pulling and squeezing to test the strength and toughness of the cable. It cannot simulate the various effects on the cable during the actual dragging process, such as ground friction, scratches from debris, etc. Therefore, the existing detection method has great limitations, the test results are not in line with reality, and the reference value is limited. Summary of the invention

[0005] In order to overcome the shortcomings of existing cable detection and fixing methods that easily cause deformation of cable fixing points or even damage to cables, the detection items cannot simulate the actual cable dragging process, have great limitations, the detection results are not in line with reality, and have limited reference value, the present invention provides an adaptive detection device for the toughness of dragged cables.

[0006] The technical solution is: a towing cable toughness adaptive detection device, including a mounting platform, a first slide rail and a first electric slider; the mounting platform is equipped with the first slide rail; two first electric sliders are slidably connected to the first slide rail; it also includes a rotation drive assembly, a second slide rail, a second electric slider and a mounting block; each first electric slider is fixedly connected to a rotation drive assembly; a baffle is provided on the left rotation drive assembly; four second slide rails distributed in a ring array are fixedly connected to the moving part of each rotation drive assembly; each second slide rail is slidably connected to a second electric slider; each second electric slider is fixedly connected to a mounting block; a sliding cavity is provided in each mounting block; the sliding cavity is inclined; a plurality of first elastic members are installed in each mounting block; the telescopic ends of all the first elastic members on the same mounting block are commonly fixedly connected to a card block; the card block slides in the corresponding sliding cavity; the sliding cavity, the first elastic member and the card block of the mounting blocks on the two first electric sliders are oppositely arranged.

[0007] Furthermore, the rotary drive assembly includes an annular guide rail and an electric slip ring; each first electric slider is fixedly connected to an annular guide rail; each annular guide rail is rotatably connected to an electric slip ring; and the electric slip ring is fixedly connected to four second slide rails.

[0008] Furthermore, a side of the mounting block facing the center of the electric slip ring is arranged in an arc shape.

[0009] Furthermore, a rubber layer is provided on the surface of the card block.

[0010] Furthermore, a guide block is included; a guide block is fixedly connected to the right side of each mounting block.

[0011] Furthermore, the guide block is arc-shaped, and all the guide blocks on the same electric slip ring are combined to form a funnel shape.

[0012] Furthermore, the right edge of the guide block is configured to be rounded.

[0013] Furthermore, it also includes a third electric slider, a second elastic member and a contact module; the third electric slider is slidably connected to the annular guide rail on the right; the second elastic member is connected to the third electric slider through an electric rotating shaft; the telescopic end of the second elastic member is connected to the contact module; and a number of irregular hard objects are arranged on the upper surface of the contact module.

[0014] Furthermore, the contact module is arc-shaped.

[0015] Furthermore, the contact module is detachably connected.

[0016] The present invention has the following advantages: the present invention realizes fixing the cable by the friction force generated by the contact between the clamp block and the cable. The greater the deformation of the cable during detection, the greater the friction between the two ends and the clamp block, and the more stable it is. Different from the existing fixing method of applying circumferential pressure to the two ends of the cable, the present invention avoids deformation of the cable fixing part or even damage to the cable due to excessive extrusion force.

[0017] By rotating the two electric slip rings in opposite directions on the corresponding annular guide rails, the friction of the block drives the cable to twist it, and the toughness strength of the cable when twisting occurs during actual use is detected, and the detection items are increased to improve the detection effect of the present invention;

[0018] The guide block guides the cables to the center of each mounting block, eliminating the need for workers to perform detailed alignment operations by observation, thus improving the efficiency of cable placement;

[0019] By contacting irregular hard objects on the module, friction is generated between the cable and the cable during movement, simulating the friction between the debris on the ground and the cable during actual use, and testing the wear resistance of the cable, increasing the testing items of the present invention to fit the actual use scenario;

[0020] The contact module is detachable and can be easily replaced with different friction objects according to the actual scenario, thereby increasing the detection effect;

[0021] By changing the position of the third electric slider, as well as the postures of the second elastic member and the contact module, the diversity of detection items for the same cable can be ensured. There is no need to replace the cable to detect different items, and multiple detection results can be intuitively measured from the same cable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-Figure 5As shown, a towing cable 1111 toughness adaptive detection device includes a mounting platform 1, a first slide rail 101 and a first electric slider 102; the mounting platform 1 is mounted with the first slide rail 101; the first slide rail 101 is slidably connected with two first electric sliders 102;

[0034] It also includes a rotary drive component, a second slide rail 103, a second electric slider 104 and a mounting block 4; each first electric slider 102 is fixedly connected to a rotary drive component; a baffle 2001 is arranged on the left rotary drive component; four second slide rails 103 distributed in a ring array are fixedly connected to the moving part of each rotary drive component; each second slide rail 103 is slidably connected to a second electric slider 104; each second electric slider 104 is fixedly connected to a mounting block 4; a sliding cavity 4001 is opened in each mounting block 4; the sliding cavity 4001 is inclined; two first elastic members 4002 are installed in each mounting block 4; the first elastic member 4002 is a spring; the telescopic ends of all the first elastic members 4002 on the same mounting block 4 are fixedly connected to a clamping block 4003; the clamping block 4003 slides in the corresponding sliding cavity 4001; the sliding cavity 4001, the first elastic member 4002 and the clamping block 4003 of the mounting block 4 on the two first electric sliders 102 are oppositely arranged.

[0035] The rotary drive assembly includes an annular guide rail 2 and an electric slip ring 3 ; each first electric slider 102 is fixedly connected to an annular guide rail 2 ; each annular guide rail 2 is rotatably connected to an electric slip ring 3 on the right side; and the electric slip ring 3 is fixedly connected to four second slide rails 103 .

[0036] The side of the mounting block 4 facing the center of the electric slip ring 3 is arranged in an arc shape to adapt to the shape of the cable 1111 .

[0037] The surface of the clamping block 4003 is provided with a rubber layer to enhance the friction and fit with the surface of the cable 1111 and improve the fixing effect.

[0038] A guide block 5 is also included; a guide block 5 is fixedly connected to the right side of each installation block 4 to guide the cable 1111 to between the installation blocks 4.

[0039] The guide block 5 is arc-shaped, and all the guide blocks 5 on the same electric slip ring 3 are combined to form a funnel shape; guiding the cable 1111 to between the installation blocks 4 is smoother and more accurate.

[0040] The right edge of the guide block 5 is configured to be rounded to improve the effect of guiding the cable 1111 toward the middle.

[0041] Existing cable 1111 testing equipment applies vertical pressure toward the axis to both ends of cable 1111 to tighten and fix them. During the testing process, in order to ensure the stability of cable 1111, strong pressure is applied to the fixing parts, and excessive pressure causes deformation of the fixing parts of cable 1111 or even damage to cable 1111, and the integrity of cable 1111 cannot be guaranteed.

[0042] Before starting the detection work, each clamping block 4003 is at the outermost position of the sliding cavity 4001 due to the pressure of the first elastic member 4002. The worker connects the electric component of the present invention to the power supply, and then controls each second electric slider 104 on the two electric slip rings 3 to drive the mounting block 4 to move, so that the diameter of the circle formed by each mounting block 4 is at the maximum limit, which is much larger than the diameter of the cable 1111 to be detected. Then the worker inserts the left end of the cable 1111 to be detected between each mounting block 4 on the two electric slip rings 3 from right to left in sequence, until the left end of the cable 1111 contacts the baffle 2001, and stops moving to the left. At this time, the left mounting blocks 4 are controlled to approach each other, so that the diameter of the circle formed by the left mounting blocks 4 is close to the diameter of the cable 1111 to be detected, until The card block 4003 contacts the surface of the cable 1111, and the card blocks 4003 on the left side remain close to the surface of the cable 1111 under the action of the first elastic member 4002. Since the sliding cavity 4001 is inclined, if the cable 1111 moves to the right, the friction between the card block 4003 and the cable 1111 drives the card block 4003 to move to the right, but the card block 4003 will be blocked by the inner wall of the sliding cavity 4001, and the card block 4003 will be stuck so that it cannot move to the right. Therefore, the friction between the card block 4003 and the cable 1111 makes it impossible for the cable 1111 to move to the right. With the restriction of the baffle 2001, the left end of the cable 1111 cannot move to the left, and the left end of the cable 1111 is fixed between the mounting blocks 4 on the left.

[0043] Then, the first electric slider 102 on the right is controlled to drive the parts thereon to move rightward along the first slide rail 101, until the first electric slider 102 and the parts thereon move to the required fixing position at the right end of the cable 1111 and then stop moving, and then the mounting blocks 4 on the right are controlled to approach each other so that the diameter of the circle formed by the mounting blocks 4 is close to the diameter of the cable 1111 to be detected, until the clamping block 4003 contacts the surface of the cable 1111, at this time, the friction force generated by the contact between the clamping block 4003 and the cable 1111, and thus the first electric slider 102 and the parts thereon cannot move rightward on the cable 1111, and at this time, if the first electric slider 102 is continued to be controlled to move rightward, the friction force between the clamping blocks 4003 on both sides and the two ends of the cable 1111, the cable 1111 is applied with pulling force to both sides, thereby simulating the scene when the cable 1111 is pulled, and realizing the detection of the toughness strength of the cable 1111 when being pulled.

[0044] The cable 1111 is fixed by the friction force generated by the contact between the above-mentioned clamping block 4003 and the cable 1111. When the cable 1111 is deformed more during the test, the friction between the two ends and the clamping block 4003 is greater, and the cable 1111 is more stable. This is different from the existing fixing method of applying circumferential pressure to the two ends of the cable 1111, and avoids excessive extrusion pressure causing deformation of the fixing part of the cable 1111 or even damage to the cable 1111.

[0045] At the same time, when both sides of the cable 1111 are stuck, the two electric slip rings 3 are controlled to rotate in clockwise and counterclockwise directions on the corresponding annular guide rails 2, and then the friction force of the blocking block 4003 is used to drive the two ends of the cable 1111 to rotate in clockwise and counterclockwise directions, respectively, to twist the cable 1111, and detect the toughness strength of the cable 1111 when it is twisted during actual use, increase the detection items, and improve the detection effect of the present invention.

[0046] When inserting the cable 1111 between the mounting blocks 4, the left end of the cable 1111 first contacts the guide blocks 5, and then the guide blocks 5 guide the cable 1111 to the center position of each mounting block 4. There is no need for workers to perform detailed alignment operations through observation, thereby improving the efficiency of placing the cable 1111.

[0047] Example 2

[0048] On the basis of Example 1, Figure 2 and Figure 6-Figure 8 As shown, it also includes a third electric slider 21, a second elastic member 22 and a contact module 23; the third electric slider 21 is slidably connected to the left side of the annular guide rail 2 on the right side; the second elastic member 22 is connected to the third electric slider 21 through an electric rotating shaft; the second elastic member 22 is a spring telescopic rod; the telescopic end of the second elastic member 22 is connected to the contact module 23; a plurality of irregular hard objects are arranged on the upper surface of the contact module 23 to simulate the debris on the ground during actual use.

[0049] The contact module 23 is arc-shaped, so as to better fit the cable 1111 for detection.

[0050] The contact module 23 is detachably connected and can be easily replaced according to actual scenarios, thereby increasing the detection effect.

[0051] The existing detection method deforms the cable 1111 through physical external forces such as pulling and squeezing, and tests the strength and toughness of the cable 1111. It is difficult to simulate the various influences of external factors during the actual dragging of the cable 1111, and has great limitations. The test results are not in line with reality and have limited reference value.

[0052] When the first electric slider 102 on the right side moves to the right, since the diameter of the circle formed by the right mounting blocks 4 is at its maximum limit and is much larger than the diameter of the cable 1111, the right end of the cable 1111, which is fixed at its left end, will be in a hanging state and contact the mounting block 4 at the lower right side, thereby simulating the actual dragging of the cable 1111. Figure 8 As shown, one end is fixed and the other end is hanging; during the movement of the first electric slider 102 to the right, the contact module 23 keeps extending upward under the action of the second elastic member 22, and then the upper side of the arc-shaped contact module 23 fits the surface of the cable 1111, and the irregular hard objects on the contact module 23 produce friction with the cable 1111 during the corresponding movement of the first electric slider 102 to the right, simulating the friction between the debris on the ground and the cable 1111 during actual use, detecting the wear resistance of the cable 1111, increasing the detection items of the present invention, and fitting the actual use scenario; in addition, the contact module 23 is a detachable connection, and different friction objects can be conveniently replaced according to the actual scenario, thereby increasing the detection effect.

[0053] In addition, after the first electric slider 102 on the right side moves a certain distance to the right, the electric shaft connecting the second elastic member 22 and the third electric slider 21 is controlled to work so that the second elastic member 22 is tilted away from the annular guide rail 2. Figure 7 As shown, at the same time, under the action of the second elastic member 22, the contact module 23 contacts the cable 1111 through the right edge, simulating the situation that the cable 1111 encounters large irregular debris and has great resistance during dragging, making it difficult to drag. At this time, the first electric slider 102 on the right stops moving to the right, and controls the first electric slider 102 on the left to move to the left, thereby applying a pulling force to the left on the cable 1111, simulating the situation that the cable 1111 encounters large irregular debris and has great resistance during dragging, making it difficult to drag. Figure 8 In the actual process shown, when the cable 1111 cannot be dragged, a pulling force is forcibly applied, and the strength of the point where the cable 1111 is stuck by the contact module 23 is detected, so that the strength of the cable 1111 that is stuck by forced pulling is detected, which is close to the actual usage scenario and ensures the authenticity of the detection.

[0054] In particular, during the above-mentioned detection operation, the third electric slider 21 can be controlled to move on the right side of the annular guide rail 2; when the third electric slider 21 rotates continuously on the annular guide rail 2, it drives the contact module 23 to perform comprehensive friction with the surface of the cable 1111 in a rotational manner, simulating the friction between the circumferential surface of the cable 1111 and debris; the third electric slider 21 can also be controlled to move to a certain position on the annular guide rail 2 and stop, simulating the actual scene where the position where friction damage is most likely to occur is tested, and then when the present invention performs wear resistance testing, both comprehensive and targeted testing is achieved.

[0055] The above-mentioned contact module 23 detects the same cable 1111 in two postures, controls the first electric slider 102 on the right to move a certain distance and then changes the position of the third electric slider 21, as well as the postures of the second elastic member 22 and the contact module 23, thereby ensuring the diversity of detection items for the same cable. There is no need to replace the cable 1111 to detect different items, and multiple detection results can be intuitively measured from the same cable 1111.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
