[0002] In the process of using the cable, in order to meet different use environments, the materials of the covering layer used on the outside of the cable and the internal wire are also different. Before using the cable with different materials and specifications, different performance detection needs to be carried out, and the tensile property detection is one of the most important performance indexes.
[0003] According to a Chinese patent with the application publication number 202210708743.9, a composite cable anti-bending and tensile detection equipment is disclosed. The equipment does not need manual direct hand pulling, but only needs to rotate the pulling screw rod, which is more time-saving and labor-saving, improves the detection efficiency, and avoids directly pulling the cable to hurt the palm of the worker. The above-mentioned cable tensile detection equipment does not have technical measures for detecting whether the cable has plastic deformation after bearing the pulling. Since a part of the cable will have metal fatigue after being pulled, the cable will have plastic deformation, and the plastic deformation amount exceeding the allowable range will also affect the use of the cable.

[0046] As a preferred scheme of the present application, the positioning ring is made of rubber.
[0047] Compared with the prior art, the present application has the following beneficial effects:
[0048] 1. In this invention, the suspension cable applies downward pressure to the axle pin, causing the two L-shaped levers and the shaft to rotate in opposite directions. This rotation drives the winding post to straighten the cable. The reverse rotation of the shaft also causes the pointer to reverse. Once the cable is fully straightened, the inspector observes the scale position of the pointer on the dial and compares it with the initial position. If there is a difference, it indicates that the cable has undergone plastic deformation during the pulling process. By calculating the scale values recorded before and after, the range of plastic deformation of the cable can be determined, making the tensile strength test of the cable more comprehensive.
[0049] 2. In this invention, during the pulling of the cable by the output rod of the hydraulic cylinder, the winding column drives the two L-shaped levers and the shaft to rotate, causing the two sliding rods, two push seats and two ball bearings to move together. This causes the positioning ring to push towards the center, positioning the outer wall of the cable. This ensures that the center of the cable and the center of the output rod of the hydraulic cylinder are on the same straight line during the testing process, resulting in more accurate measurements. At the same time, the positioning effect of the two positioning rings on the cable ensures that the cable and the winding column remain perpendicular during the plastic deformation testing of the cable, making the detection of the plastic deformation of the cable more accurate.
[0050] 3. In this invention, after the test is completed, the counterweight continues to move downwards under the force of gravity, and the suspension cable pulls down the pin, causing the L-shaped lever and the shaft to rotate, which in turn causes the winding column to rotate. The winding column then causes the slide bar, the push seat, and the ball to move together. Under the rebound force of the first spring, the ball rolls from the inner side of the guide rail to the inner side of the tensioning seat, causing the two positioning rings to open, making it easier to remove the cable around the winding column and improving the convenience of the test.

[0067] Further, with reference to Figure 6 、 Figure 7 shown:
[0068] The detection part 300 further comprises a strip-shaped groove 3051, a sliding rod 3052, a support column 3053, a positioning ring 3054, a pushing seat 3055, an inner ball cage 3056, a ball 3057, a tensioning seat 3058 and a guide rail 3059. The strip-shaped grooves 3051 are equiangularly distributed on the outer wall of the winding column 305, and the number is four. The sliding rods 3052 are slidingly installed in the inner part of the winding column 305, and the number is two. The two sliding rods 3052 are symmetrically distributed about the middle part of the winding column 305. The support columns 3053 are equiangularly and fixedly installed on the outer wall of one end of the two sliding rods 3052 close to each other, and the support columns 3053 movably penetrate the strip-shaped grooves 3051. The positioning rings 3054 are slidingly installed on the outer wall of the winding column 305, and the number is two. The two positioning rings 3054 are symmetrically distributed about the middle part of the winding column 305, and the positioning rings 3054 are fixedly installed on the outer wall of the corresponding support columns 3053. The positioning rings 3054 are made of rubber material. The pushing seats 3055 are fixedly installed on the other end of the two sliding rods 3052 away from each other. The inner ball cage 3056 is arranged on the end of the pushing seat 3055 away from the sliding rod 3052. The ball 3057 is rotatably installed in the inner part of the inner ball cage 3056. The tensioning seats 3058 are symmetrically arranged on the top of the top plate 302 about the middle part of the top plate 302, and the number is two. The guide rails 3059 are fixedly installed on the side face of the two tensioning seats 3058 close to each other, and the positions of the two guide rails 3059 correspond to the positions of the two pushing seats 3055.
[0069] Specifically, during the pulling of the cable by the output rod of the hydraulic oil cylinder 203, the winding column 305 drives the two L-shaped levers 304 and the shaft rod 303 to rotate. During the movement of the winding column 305, the two sliding rods 3052, the two pushing seats 3055 and the two balls 3057 also move together. Initially, the two balls 3057 roll along the inner side face of the two tensioning seats 3058, and then roll onto the inner side face of the two guide rails 3059. During this period, the two balls 3057 move towards the middle, further pushing the two pushing seats 3055 and the two sliding rods 3052 to move towards the middle along the inner wall of the winding column 305. The movement of the two sliding rods 3052 towards the middle also drives the two positioning rings 3054 to move towards the middle through the connecting action of the support column 3053, thereby positioning the outer wall of the cable. This ensures that the center of the cable and the center of the output rod of the hydraulic oil cylinder 203 are on the same straight line during the detection process, so that the measurement is more accurate. Moreover, due to the positioning action of the two positioning rings 3054 on the cable, the cable can maintain a vertical state with the winding column 305 during the detection of the plastic deformation of the cable, so that the detection of the plastic deformation of the cable is more accurate.
[0070] Further, with reference to Figure 7 , it is shown that
[0071] The detection part 300 further comprises a first spring 30510, which is sleeved on the periphery of the sliding rod 3052 and fixedly installed between the end of the winding column 305 and the side of the push-pull seat 3055.
[0072] Specifically, during the two push-pull seats 3055 moving towards the middle, the two first springs 30510 are compressed to generate elastic deformation. After the cable is removed from the hook 204, the gravity of the counterweight 308 continues to move downward, and the suspension cable 307 pulls down the shaft pin 306, drives the L-shaped lever 304 and the shaft rod 303 to rotate, further drives the winding column 305 to rotate, moves the sliding rod 3052, the push-pull seat 3055 and the ball 3057 together through the winding column 305, and makes the ball 3057 roll from the inner side of the guide rail 3059 to the inner side of the tension seat 3058 under the elastic force of the first spring 30510, so that the two positioning rings 3054 are opened, the cable around the winding column 305 is easily removed, and the convenience of detection is improved.
[0073] Further, with reference to Figure 8
[0074] The detection part 300 further comprises a telescopic rod 30511, a fixed plate 30512, a telescopic hole 30513, a limiting baffle 30514 and a second spring 30515. The telescopic rod 30511 is fixedly installed on the two ends of the side away from the two tension seats 3058. The fixed plate 30512 is fixedly installed on the front and back of the top plate 302. The telescopic hole 30513 is throughly provided on the two ends of the side close to the two fixed plates 30512, and the specification and position thereof are matched with the telescopic rod 30511. The telescopic rod 30511 is slidingly installed in the telescopic hole 30513. The limiting baffle 30514 is fixedly installed on the end of the outer wall of the telescopic rod 30511 away from the tension seat 3058. The second spring 30515 is sleeved on the periphery of the telescopic rod 30511 and fixedly installed between the fixed plate 30512 and the limiting baffle 30514.
[0075] Specifically, through the sliding connection of the telescopic hole 30513 and the telescopic rod 30511, the floating space of the tension seat 3058 and the guide rail 3059 is ensured, so that the positioning distance between the two positioning rings 3054 can be adjusted to facilitate the detection and positioning of cables of different thicknesses. When the cable is thicker, the distance between the two positioning rings 3054 becomes larger, and the reaction force of the cable outer wall on the positioning ring 3054 is transmitted to the guide rail 3059 and the tension seat 3058 through the slide rod 3052, the push rod seat 3055 and the ball 3057, causing the tension seat 3058 to move towards the fixed plate 30512, driving the telescopic rod 30511 to slide inside the telescopic hole 30513, causing the second spring 30515 to elastically deform. Through the elastic force of the second spring 30515, the guide rail 3059 is always in contact with the ball 3057, ensuring that the two positioning rings 3054 have good positioning effect on the cable.
[0076] In the working process of the anti-tensile property detection device for cable processing, one end of the cable sample to be detected is first wound on the outer wall of the hook 204, the cable is locked at the folded part by the fixing buckle, the other end of the cable is wound around the wire winding column 305, the cable is locked at the folded part by the fixing buckle, the hydraulic cylinder 203 is started, the output rod of the hydraulic cylinder 203 moves to pull the cable, further drives the two L-shaped levers 304 and the shaft 303 to rotate under the connection of the wire winding column 305, until the L-shaped lever 304 abuts against the inner wall of one side of the limiting groove 3021, the shaft 303 drives the pointer 309 to rotate, at this time, the scale position of the pointer 309 corresponding to the dial 3010 is recorded, then the computer sets the tension parameter of the hydraulic cylinder 203, the output rod of the hydraulic cylinder 203 applies tension to the cable, if the cable breaks, it means that the cable tensile property is unqualified, if the cable does not break, the output rod of the hydraulic cylinder 203 returns to the original position, at the same time, under the action of the gravity of the counterweight 308, the suspension cable 307 presses the shaft pin 306, further pulls the two L-shaped levers 304 through the shaft pin 306, drives the wire winding column 305 to rotate in the opposite direction, and straightens the cable, at the same time, the reverse rotation of the shaft 303 drives the pointer 309 to rotate in the opposite direction, when the cable is completely straightened, the detection personnel observe the scale position of the pointer 309 corresponding to the dial 3010, if it is consistent with the initial recorded position, it means that the cable has not been elongated, if there is a difference between the scale position of the pointer 309 corresponding to the dial 3010 and the initial recorded position, it means that the cable has plastic deformation in the pulling process, and the range of plastic deformation of the cable can be determined by calculating the scale values recorded before and after, if the range of plastic deformation exceeds the allowable range of the cable in use, it means that the cable tensile property is unqualified.
[0077] It needs to be explained that, when the output rod of the hydraulic cylinder 203 pulls the cable, the winding post 305 drives the two L-shaped levers 304 and the shaft 303 to rotate, and during the movement of the winding post 305, the two sliding rods 3052, the two push seats 3055 and the two ball beads 3057 move together. Initially, the two ball beads 3057 roll along the inner side surface of the two tensioning seats 3058, until the two ball beads 3057 roll onto the inner side surface of the two guide rails 3059, during which the two ball beads 3057 move towards the middle, further pushing the two push seats 3055 and the two sliding rods 3052 to move towards the middle along the inner wall of the winding post 305. The movement of the two sliding rods 3052 towards the middle also drives the two positioning rings 3054 to move towards the middle through the connecting action of the support 3053, positioning the outer wall of the cable, ensuring that the center of the cable is in the same straight line as the center of the output rod of the hydraulic cylinder 203 during the detection process, and the measurement is more accurate. Moreover, due to the positioning action of the two positioning rings 3054 on the cable, the cable can maintain a vertical state with the winding post 305 during the detection of the plastic deformation of the cable, and the detection of the plastic deformation of the cable is more accurate.
[0078] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application.
