Description

Technical Field

[0001] The utility model relates to the technical field of anti-stretching detection devices, in particular to an anti-stretching detection device with a traction structure. Background Art

[0002] The cable and wire stretch detection device is a device used to detect the tensile force of cables and wires. It can determine whether the tension on the cables and wires exceeds the design standard by measuring the tension on the cables and wires to ensure the safe operation of the cables and wires. The cable and wire stretch detection device is usually composed of a stretch sensor, a signal collector, a data processor and a display. The stretch sensor is used to measure the tension on the cables and wires and transmit the signal to the signal collector. The signal collector is responsible for converting the tension signal measured by the sensor into a digital signal and transmitting it to the data processor. The data processor processes the collected data and makes judgments and alarms according to the preset standards. The display will display the processed data in digital or graphical form for the operator to observe and analyze.

[0003] However, most existing stretching detection devices fix the two ends of the cable or wire before pulling, and are unable to stretch the cable continuously and at a fixed distance. At the same time, if the two ends are fixed for stretching, if the position of the fixed cable is offset, the stretching angle of the cable will be offset, thereby making the detection data inaccurate and affecting the results.

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: an anti-stretching detection device with a traction structure, comprising a body 1, a square plate 3 is fixedly connected to the top surface of the body 1, a cylinder 4 is fixedly connected to the surface of the square plate 3, and a detector 5 is fixedly connected to the inner wall of the body 1. When the cylinder 4 is retracted, the output shaft of the cylinder 4 will pull the force block 27 to reset, and the force block 27 will drive the sliding box 24 to move to the right together through the sliding rod 26, so that the cable is pulled and stretched to the bottom of the detector 5 through the traction block 28 for detection. A control unit 2 is provided inside the body 1, and the control unit 2 includes: a connecting ring 21, a resistance ring 22, a connecting circular plate 23, a sliding box 24, a limiting groove 25, a sliding rod 26, a force block 27, a traction block 28, a resistance block 29, a sliding groove 210, an arc rod 211, an arc spring 212, a groove 213, a cross bar 214, a circular hole 215, a telescopic spring 216, a connecting rod 217, a support rod 218, a circular ring 219, a connecting block 220, a reset spring 221, a hook 222, and a torsion spring 223.

[0026] The side surface of the connecting ring 21 is fixedly connected to the inner wall of the body 1, and the inner side of the connecting ring 21 is fixedly connected with a contact ring 22. The inner wall of the body 1 is fixedly connected with a circular plate 23. The inner wall of the body 1 is slidably connected with a sliding box 24. A limiting groove 25 is provided on the surface of the body 1. A sliding rod 26 is fixedly connected to the top surface of the sliding box 24. The wires or cables to be detected pass through the body 1 and pass through the contact ring 22, the sliding box 24 and the connecting circular plate 23. The cylinder 4 is started, and the output shaft of the cylinder 4 will push the force block 27 to move, and the force block 27 will slide along the limiting groove 25 through the sliding rod 26. At the same time, the sliding rod 26 will drive the sliding box 24 to slide along the inner wall of the body 1. The top surface of the sliding rod 26 is fixedly connected with the force block 27. The side of the force block 27 close to the cylinder 4 is fixedly connected to the output shaft of the cylinder 4. The traction block 28 is slidably connected to the inner wall of the sliding box 24. The traction block 28 and the left side of the traction block 28 are fixed A resistance block 29 is connected, and a slide groove 210 is provided on the surface of the sliding box 24. The resistance block 29 passes through the slide groove 210 and is slidably connected. The groove 213 is provided on the right side surface of the traction block 28. The inner side of the groove 213 is fixedly connected with a cross bar 214. A circular hole 215 is provided on the top surface of the traction block 28. A connecting rod 217 passes through the inner side of the circular hole 215. The top end of the connecting rod 217 is fixedly connected to the inner wall of the sliding box 24. The inner side of the circular hole 215 is fixedly connected with a telescopic spring 216. When the hook 222 rotates a certain distance and the cross bar 214 exceeds the L-shaped inner side of the hook 222, the stretched torsion spring 223 will pull the hook 222 to reset, thereby causing the inner side of the hook 222 to clamp the cross bar 214, so that the traction block 28 will not be reset. At the same time, when the traction block 28 contracts, the telescopic spring 216 will be stretched, and the top end of the telescopic spring 216 is fixedly connected to the inner wall of the sliding box 24. A support rod 218 penetrates the right side surface of the sliding box 24, and the support rod 218 is slidably connected to the sliding box 24. A ring 219 is fixedly connected to one end of the support rod 218 away from the sliding box 24, and a connecting block 220 is fixedly connected to one end of the support rod 218 away from the ring 219. A hook 222 is hingedly connected to the surface of the connecting block 220 away from the support rod 218, and a return spring 221 is fixedly connected between the ring 219 and the surface of the sliding box 24. There are three groups of traction blocks 28, and the three groups of traction blocks 28 are respectively arranged in a circular array with the center line of the sliding box 24 as the axis. The traction blocks 28 arranged in the three groups of circular arrays lock the cable toward the middle, so that the traction blocks 28 can fix the cable in the center, prevent the cable from tilting at an angle when being pulled, and cause the traction force to deviate, so that the cable can be stretched evenly, thereby making the detection data more accurate.The hook 222 is in an L-shape. When the ring 219 contacts the connecting circular plate 23, the ring 219 will push the support rod 218 relatively, and the support rod 218 will push the hook 222 through the connecting block 220, so that the hook 222 no longer hooks the cross bar 214, and then the traction block 28 is pulled back to its original position through the stretched telescopic spring 216, so that the cylinder 4 will not pull the cable back when the sliding box 24 slides again, and a torsion spring 223 is fixedly connected between the hook 222 and the connecting block 220. When the traction block 28 shrinks to the middle, the cable will be locked. At the same time, when the traction block 28 shrinks, the cross bar 214 will contact the inclined surface of the hook 222, so that the hook 222 hinged to the connecting block 220 rotates downward, and the torsion spring 223 is stretched. The traction block 28 and the other two groups of traction blocks 28 are penetrated by an arc rod 211, and an arc spring 212 is fixedly connected between each two groups of traction blocks 28. When the sliding box 24 moves to the leftmost side of the body 1, the abutment ring 22 will abut against the inclined surface of the abutment block 29, so that the abutment block 29 drives the traction block 28 to shrink toward the middle, and the three groups of traction blocks 28 are shrinked toward the middle together through the arc rod 211, and the arc spring 212 is compressed.

[0027] Based on the above embodiment, the wire or cable to be detected is passed through the body 1 and through the abutment ring 22, the sliding box 24 and the connecting circular plate 23, and the cylinder 4 is started. The output shaft of the cylinder 4 will push the force block 27 to move, and the force block 27 will slide along the limit groove 25 through the slide bar 26. At the same time, the slide bar 26 will drive the sliding box 24 to slide along the inner wall of the body 1. When the sliding box 24 moves to the leftmost side of the body 1, the abutment ring 22 will abut against the inclined surface of the abutment block 29, thereby causing the abutment block 29 to move. The contact block 29 drives the traction block 28 to retract toward the middle, and the three groups of traction blocks 28 are retracted toward the middle together through the arc rod 211, and the arc spring 212 is compressed. When the traction block 28 retracts toward the middle, the cable is locked. At the same time, when the traction block 28 retracts, the cross bar 214 will contact the inclined surface of the hook 222, so that the hook 222 hinged to the connecting block 220 rotates downward, and the torsion spring 223 is stretched. When the hook 222 rotates a certain distance and the cross bar 214 exceeds When the hook 222 is pulled to the inner side of the L-shape, the stretched torsion spring 223 will pull the hook 222 to reset, so that the inner side of the hook 222 clamps the cross bar 214, so that the traction block 28 will not be reset. At the same time, when the traction block 28 contracts, the telescopic spring 216 will be stretched. When the cylinder 4 contracts, the output shaft of the cylinder 4 will pull the force block 27 to reset, and the force block 27 will drive the sliding box 24 to move to the right through the sliding rod 26, so that the cable is pulled and stretched to the detector 5 through the traction block 28. When the circular ring 219 contacts the connecting circular plate 23, the circular ring 219 will push the support rod 218 relatively, and the support rod 218 will push the hook 222 through the connecting block 220, so that the hook 222 no longer hooks the cross bar 214, and then the traction block 28 is pulled back to its original position through the stretched telescopic spring 216, so that the cylinder 4 will not pull the cable back when sliding the sliding box 24 again. Through repeated starting of the cylinder 4, the cable can be pulled at a fixed distance and stably for detection.

[0028] At the same time, the cable is locked toward the middle by three groups of traction blocks 28 arranged in a circular array, so that the traction block 28 can center and fix the cable to prevent the cable from tilting at an angle when being pulled, causing the traction force to shift, so that the cable can be stretched evenly, thereby making the detection data more accurate.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
