Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a wear-resistant detection device for cable production. Background Art

[0002] Cable wear resistance test is a test method used to evaluate the wear resistance of the cable outer sheath. During the actual installation, use and maintenance of the cable, it is inevitable that the cable will be subjected to various forms of friction, such as contact friction with the ground, building surface, other cables or equipment. In industrial plants, cables are often dragged and rubbed on the ground. If the wear resistance is poor, the cable outer sheath is easily damaged, resulting in the exposure of the internal core wire, which in turn causes short circuits, leakage and other faults, and ends the normal use cycle of the cable prematurely.

[0003] In the prior art, when performing abrasion resistance testing on cables, the cable sample is fixed on the workbench of the test equipment, and a grinding head with a certain friction coefficient is used to make reciprocating motion on the cable surface at a certain speed under a specified load. After the test, the cable sample is visually inspected to observe whether the cable outer sheath has wear marks, scratches, damage, fuzzing, etc.

[0004] During the wear resistance test of the cable, the wear of the insulation layer gradually increases. Therefore, the wear of the cable insulation layer is only checked after the friction of the grinding head is completed. The specific situation of the cable during the friction of the grinding head cannot be obtained, which leads to limitations.

[0005] To this end, we propose a wear-resistant detection device for cable production. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a wear-resistant detection device for cable production, which overcomes the deficiencies in the prior art and aims to solve the problems in the background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a wear-resistant detection device for cable production, comprising:

[0008] A base, a fixing block, a mounting clamp and a friction block; the base is provided with a fixing groove; the fixing block is slidably connected in the fixing groove; the mounting clamp is mounted on the fixing block; the friction block is mounted on the base;

[0009] The base is provided with a diameter detection mechanism; the diameter detection mechanism can detect the diameter of the cable when the friction block rubs the cable.

[0010] Preferably, the diameter detection mechanism includes a detection block, a fixed rod, a detection rod and a detection pressure sensor; the detection block is mounted on the base; the fixed rod is fixedly connected to the detection block; the detection rod is rotatably connected to the detection block; the detection pressure sensor is fixedly connected to the detection block; a detection spring is fixedly connected between the detection pressure sensor and the detection rod; the upper ends of the fixed rod and the detection rod are bent outward.

[0011] Preferably, a lifting slot is provided on the base; a lifting electric push rod is fixedly connected in the lifting slot, the detection block is slidably connected in the lifting slot, and the detection block is fixedly connected to the output end of the lifting electric push rod.

[0012] Preferably, a synchronous gear is rotatably connected to the base; a synchronous rack is fixedly connected to the fixed block; the synchronous gear is located between the two synchronous racks and meshes with the synchronous racks; a fixed motor is fixedly connected in the fixed groove; a screw rod that cooperates with the fixed block thread is fixedly connected to the output end of the fixed motor.

[0013] By clamping the fixed rod and the detection rod on the detection block on both sides of the worn part of the cable, the wear of the cable can be detected by the pressure change transmitted to the detection pressure sensor by the detection spring. Therefore, the present invention can detect the wear of the cable during the friction of the cable.

[0014] Preferably, a No. 1 sliding groove is provided on the detection block; a No. 1 sliding block is slidably connected in the No. 1 sliding groove; a No. 2 sliding groove is provided on the detection rod; a No. 2 sliding block is slidably connected in the No. 2 sliding groove; an adjusting rod is threadedly connected to the detection block; the adjusting rod is rotatably connected to the No. 1 sliding block; the No. 2 sliding block is rotatably connected to the No. 1 sliding block; a fixing bolt is threadedly connected to the detection rod; the fixing bolt squeezes the No. 2 sliding block.

[0015] By adjusting the upper and lower heights of the No. 1 sliding block and the No. 2 sliding block, the position of the rotation center of the detection rod is adjusted, the length of the detection rod above the No. 2 sliding block is shortened, and the length below the No. 2 sliding block is increased, thereby amplifying the wear of the cable and improving the detection accuracy of the cable wear.

[0016] Preferably, a connecting groove is provided on the fixed block; a connecting block is slidably connected in the connecting groove; a pressure screw is rotatably connected to the fixed block; the pressure screw is threadedly engaged with the connecting block; a pressure groove is provided on the connecting block; the mounting clip is slidably connected in the pressure groove; an installation pressure sensor is fixedly connected in the pressure groove; and an installation spring is fixedly connected between the installation pressure sensor and the mounting clip.

[0017] Preferably, a rotating groove is provided on the base; a rotating motor is fixedly connected in the rotating groove, and a rotating block is threadedly connected in the rotating groove; the friction block is fixedly connected to the rotating block, and the friction block is cylindrical; a rotating gear is fixedly connected to the rotating block; and a gear meshing with the rotating gear is fixedly connected to the output end of the rotating motor.

[0018] Preferably, an F-shaped block is fixedly connected to the base.

[0019] In the present invention, after the cable rubs against the friction block for a period of time, the rotating motor drives the rotating block and the friction block to rotate. Since the rotating block is threadedly connected in the rotating groove, the friction block moves upward at the same time during rotation, thereby changing the position where the friction block rubs against the cable. When the cable is installed, the cable passes between the two rods of the F-shaped block and contacts the friction block, so the F-shaped block limits the cable to prevent the cable from moving up and down. Therefore, the present invention can change the position where the friction block rubs against the cable, and prevent the insulation layer of the cable from adhering to the friction block after multiple frictions, thereby affecting the friction effect of the subsequent sequence.

[0020] The present invention spirally rotates the rotating block to make the friction block rotate and move upward, thereby changing the position where the friction block rubs against the cable, thereby preventing the cable on the friction block from rubbing at the same position multiple times, causing the cable insulation layer to adhere to the same position, thereby changing the friction coefficient and affecting the friction effect.

[0021] Beneficial effects of the present invention:

[0022] 1. The present invention clamps the fixed rod and the detection rod on the detection block on both sides of the worn part of the cable, so as to detect the change in pressure transmitted to the detection pressure sensor by the detection spring, and can detect the wear of the cable. Therefore, the present invention can detect the wear of the cable during the friction of the cable.

[0023] 2. The present invention adjusts the upper and lower heights of the No. 1 sliding block and the No. 2 sliding block, thereby adjusting the position of the rotation center of the detection rod, shortening the length of the detection rod above the No. 2 sliding block, and increasing the length below the No. 2 sliding block, thereby amplifying the wear of the cable and improving the detection accuracy of the cable wear.

[0024] 3. The present invention spirally rotates the rotating block to make the friction block rotate and move upward, thereby changing the position where the friction block and the cable rub against each other, thereby preventing the cable on the friction block from rubbing against the same position multiple times, causing the cable insulation layer to adhere to the same position, thereby changing the friction coefficient and affecting the friction effect.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 4 and 6, a wear-resistant detection device for cable production, comprising:

[0034] Base 1, fixing block 11, mounting clip 12 and friction block 13; a fixing groove 14 is provided on the base 1; the fixing block 11 is slidably connected in the fixing groove 14; the mounting clip 12 is mounted on the fixing block 11; the friction block 13 is mounted on the base 1;

[0035] The base 1 is provided with a diameter detection mechanism, which can detect the diameter of the cable when the friction block 13 rubs the cable.

[0036] In the present invention, the diameter detection mechanism includes a detection block 21, a fixed rod 22, a detection rod 23 and a detection pressure sensor 24; the detection block 21 is installed on the base 1; the fixed rod 22 is fixedly connected to the detection block 21; the detection rod 23 is rotatably connected to the detection block 21; the detection pressure sensor 24 is fixedly connected to the detection block 21; a detection spring 25 is fixedly connected between the detection pressure sensor 24 and the detection rod 23; the upper ends of the fixed rod 22 and the detection rod 23 are bent outward.

[0037] In the present invention, a lifting slot 4 is provided on the base 1; a lifting electric push rod 41 is fixedly connected in the lifting slot 4, a detection block 21 is slidably connected in the lifting slot 4, and the detection block 21 is fixedly connected to the output end of the lifting electric push rod 41.

[0038] In the present invention, a synchronous gear 64 is rotatably connected to the base 1; a synchronous rack 65 is fixedly connected to the fixed block 11; the synchronous gear 64 is located between the two synchronous racks 65 and meshes with the synchronous rack 65; a fixed motor 66 is fixedly connected in the fixed groove 14; and a screw rod that is threadedly matched with the fixed block 11 is fixedly connected to the output end of the fixed motor 66.

[0039] In the present invention, the intercepted cable to be tested is passed around the friction block 13, and the two ends of the cable are clamped on the mounting clamps 12 on the two fixed blocks 11. The fixed motor 66 drives the corresponding screw to rotate, so that the fixed block 11 moves, and the other fixed block 11 is driven by the synchronous rack 65 and the synchronous gear 64 to move in the opposite direction, so that the two fixed blocks 11 move in opposite directions on the base 1, thereby driving the cable to rub back and forth on the surface of the friction block 13, so that the insulation layer of the cable is worn by the friction block 13;

[0040] In the process of the cable moving back and forth, when the part of the cable worn by the friction block 13 passes above the detection block 21, the lifting electric push rod 41 pushes the detection block 21 upward, so that the fixing rod 22 and the detection rod 23 on the detection block 21 are inserted into the two sides of the cable. The detection rod 23 clamps the cable under the action of the detection spring 25. Therefore, after the insulation layer of the cable is worn, the diameter of the cable is reduced. The more serious the wear, the longer the distance that the detection spring 25 pushes the detection rod 23 to rotate. Therefore, the pressure on the detection pressure sensor 24 is smaller and changes linearly, so that the diameter of the cable is calculated, and then the wear of the cable can be obtained. After the detection is completed, the detection block 21 returns to the lifting slot 4;

[0041] The present invention clamps the fixed rod 22 and the detection rod 23 on the detection block 21 on both sides of the worn part of the cable, so that the pressure change transmitted to the detection pressure sensor 24 by the detection spring 25 can detect the wear of the cable. Therefore, the present invention can detect the wear of the cable during the friction process of the cable.

[0042] In the present invention, a No. 1 sliding groove 3 is provided on the detection block 21; a No. 1 sliding block 31 is slidably connected in the No. 1 sliding groove 3; a No. 2 sliding groove 32 is provided on the detection rod 23; a No. 2 sliding block 33 is slidably connected in the No. 2 sliding groove 32; an adjusting rod 34 is threadedly connected on the detection block 21; the adjusting rod 34 is rotatably connected to the No. 1 sliding block 31; the No. 2 sliding block 33 is rotatably connected to the No. 1 sliding block 31; a fixing bolt 35 is threadedly connected on the detection rod 23; the fixing bolt 35 squeezes the No. 2 sliding block 33.

[0043] In the present invention, the fixing bolt 35 on the detection rod 23 is loosened, and then the adjustment rod 34 is rotated, so that the No. 1 sliding block 31 moves with the No. 2 sliding block 33, and the rotation center of the detection rod 23 is adjusted, and then the force arm when the rotating rod rotates is adjusted. Therefore, the rotation center of the detection rod 23 can be adjusted upward, so that the upper part of the rotation center of the detection rod 23 rotates a smaller distance, while the lower part rotates a larger distance, so that the worn part of the cable is magnified to the lower end of the detection rod 23, and the force transmitted to the detection spring 25 and the detection pressure sensor 24 is amplified, thereby improving the detection accuracy;

[0044] The present invention adjusts the upper and lower heights of the No. 1 sliding block 31 and the No. 2 sliding block 33, thereby adjusting the position of the rotation center of the detection rod 23, shortening the length of the detection rod 23 above the No. 2 sliding block 33, and increasing the length below the No. 2 sliding block 33, thereby amplifying the wear of the cable and improving the detection accuracy of the cable wear.

[0045] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 1 and 5 In the present invention, a connecting groove 5 is provided on the fixed block 11; a connecting block 51 is slidably connected in the connecting groove 5; a pressure screw 52 is rotatably connected to the fixed block 11; the pressure screw 52 is threadedly matched with the connecting block 51; a pressure groove 53 is provided on the connecting block 51; the mounting clip 12 is slidably connected in the pressure groove 53; an installation pressure sensor 54 is fixedly connected in the pressure groove 53; an installation spring 55 is fixedly connected between the installation pressure sensor 54 and the mounting clip 12.

[0046] In the present invention, after clamping both ends of the cable on the mounting clamp 12, the staff rotates the pressure screw 52 to move the connecting block 51 in the direction away from the friction block 13, and then pulls the mounting clamp 12 and the cable through the mounting spring 55. The mounting pressure sensor 54 can detect the pressure on the mounting clamp 12 and the cable, and then adjusts the pressure on the cable by rotating the pressure screw 52, ​​so that the present invention can adjust the pressure between the cable and the friction block 13 when the cable is worn, thereby improving the detection range.

[0047] In the present invention, a rotating groove 6 is provided on the base 1; a rotating motor 61 is fixedly connected in the rotating groove 6, and a rotating block 62 is threadedly connected in the rotating groove 6; a friction block 13 is fixedly connected to the rotating block 62, and the friction block 13 is cylindrical; a rotating gear 63 is fixedly connected to the rotating block 62; and a gear meshing with the rotating gear 63 is fixedly connected to the output end of the rotating motor 61.

[0048] In the present invention, an F-shaped block 67 is fixedly connected to the base 1 .

[0049] In the present invention, after the cable rubs against the friction block 13 for a period of time, the rotating motor 61 drives the rotating block 62 and the friction block 13 to rotate. Since the rotating block 62 is threadedly connected in the rotating groove 6, the friction block 13 moves upward at the same time during the rotation, thereby changing the position where the friction block 13 rubs against the cable, and when installing the cable, the cable passes between the two rods of the F-shaped block 67 and contacts the friction block 13, so the F-shaped block 67 limits the cable to prevent the cable from moving up and down. Therefore, the present invention can change the position where the friction block 13 rubs against the cable, and prevent the insulation layer of the cable from adhering to the friction block 13 after multiple frictions, thereby affecting the friction effect of the subsequent sequence;

[0050] The present invention spirally rotates the rotating block 62 to make the friction block 13 rotate and move upward, thereby changing the position where the friction block 13 rubs against the cable, thereby preventing the cable on the friction block 13 from rubbing multiple times at the same position, causing the cable insulation layer to adhere to the same position, thereby changing the friction coefficient and affecting the friction effect.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected; the scope of the present invention to be protected is defined by the attached claims and their equivalents.
