Description

Technical Field

[0001] The invention relates to the technical field of optical cable measurement, and in particular to a handheld device for measuring the horizontal position of an optical cable. Background Art

[0002] With the continuous development of science and technology, the demand for communication is also constantly increasing. Whether it is production and life or military aspects, the demand for communication is very high. The main equipment used in communication is optical cable. Optical cables are generally buried underground, and then stone tablets are erected to mark the location of the optical cables. Although the erection of stone tablets can roughly mark the location of the optical cables, it is still difficult to find the exact location of the optical cables during the maintenance process. If the location of the optical cables cannot be accurately found, it will not only lead to meaningless excavation, but also delay maintenance time, and even damage the optical cables during the excavation process. To measure the precise position of the optical cables, it is generally necessary to use optical cable horizontal position measuring equipment.

DETAILED DESCRIPTION

[0017] Reference Figure 1-7 , a handheld device for measuring the horizontal position of an optical cable, comprising a bottom plate 1, a cover body 2 is fixedly connected to the upper surface of the bottom plate 1, a detector 13 is fixedly connected to the inner bottom wall of the cover body 2, the detector 13 is connected to a numerical control analysis host through wireless communication, so as to analyze the position of the optical cable according to the measured information, which is a prior art and will not be described in detail here, a display 3 is fixedly connected to the upper surface of the cover body 2, the display 3 is used to display the information detected by the detector 13, a handle 4 is fixedly connected to the side wall of the cover body 2, and a hammer mechanism is provided at the cover body 2 and the bottom plate 1; The hammer mechanism includes two first rotating shafts 5, which are respectively connected to the two side walls opposite to the cover body 2 through bearings, and one end of the first rotating shaft 5 located in the cover body 2 is fixedly connected to the first rotating disk 6, and a fixing rod 8 is fixedly connected between the two first rotating disks 6. The side wall of the cover body 2 is fixedly connected to a motor 7, which is a fixed-torque micro motor, which can output a fixed torque, so that the rotation speed is related to the resistance it encounters when rotating. The output shaft of the motor 7 is fixedly connected to one of the first rotating shafts 5, and a hammer block 9 is slidably connected through the bottom plate 1. Two vertical plates 10 are fixedly connected to the upper surface of the hammer block 9, and a mounting rod 11 is fixedly connected between the two vertical plates 10. The mounting rod 11 and the fixing rod 8 are fixedly connected to a connecting block 12 through a bearing. The handle 4 is used to make the walking wheel 16 contact the ground to be tested. At this time, the detector 13 and the motor 7 are turned on, and the device is pushed forward. During the pushing process, the motor 7 drives the first turntable 6 to rotate through the first rotating shaft 5, and the rotation of the first turntable 6 drives the fixed rod 8 to rotate, and then through the transmission of the connecting block 12, the hammer block 9 is made to reciprocate up and down continuously to hammer the ground. During the hammering process, information is received through the detector 13, and analyzed and calculated by the remote host to measure the position of the optical cable. The hammer test is performed by the reciprocating hammer block 9. Compared with the ball throwing test in the prior art, the scattered and difficult to manage ball is avoided. At the same time, it can be applicable to tests of various frequencies, making the application of the equipment wider, and the tests of different frequencies are coordinated with the subsequent functions to achieve accurate measurement.

[0018] A walking mechanism is provided at the bottom plate 1, and the walking mechanism includes two wheel holes 14 opened in the bottom plate 1, and a second rotating shaft 15 is rotatably connected between the two inner side walls opposite to the wheel hole 14 through a bearing, and the second rotating shaft 15 penetrates and is fixedly connected to two walking wheels 16 and two first pulleys 17. Two third rotating shafts 18 are rotatably connected between the two inner side walls opposite to the cover body 2 through a bearing, and the two third rotating shafts 18 penetrate and are fixedly connected to two second pulleys 19, two second rotating disks 21 and a first bevel gear 42, and the first pulley 17 and the corresponding second pulley 19 are jointly matched with a synchronous belt 20, and the outer walls of the first pulley 17 and the second pulley 19 are both provided with teeth, and the inner wall of the synchronous belt 20 is also provided with teeth, and the first pulley 17, the second pulley 19 and the synchronous belt 20 are meshing transmission to ensure the smooth transmission.

[0019] A control mechanism is provided at the bottom plate 1 and the cover body 2, and the control mechanism includes two sliding sleeves 22, the sliding sleeve 22 is fixedly connected to the upper surface of the bottom plate 1 through a rod, the sliding sleeve 22 is sealed and slidably connected to a slider 23, the lower surface of the sliding sleeve 22 is fixedly connected to a functional block 24, the functional block 24 and the sliding sleeve 22 are jointly provided with a through hole 25, the through hole 25 connects the functional block 24 with the sliding sleeve 22, the functional block 24 is sealed and slidably connected to a control block 26 through the through hole 25, and two electric push rods 27 are fixedly connected to the upper surface of the bottom plate 1, the output end of the electric push rod 27 is fixedly connected to the lower surface of the corresponding control block 26, and the electric push rod 27 is connected to the detector 13 through a PLC control circuit. The PLC control circuit can control the extension length of the electric push rod 27 according to the strength of the optical cable signal detected by the detector 13. The stronger the optical cable signal strength, the longer the extension length. This is a prior art and will not be described in detail here. The sleeve 22 and the functional block 24 are filled with hydraulic oil, and the contact area between the control block 26 and the hydraulic oil is smaller than the contact area between the slider 23 and the hydraulic oil, so that a smaller force applied at the control block 26 can generate a larger force at the slider 23. At this time, the electric push rod 27 with a smaller thrust can be selected, and further The selection volume of the electric push rod 27 is reduced. During the detection process, when the detector 13 detects that it is close to the position of the optical cable, the PLC control circuit extends the electric push rod 27. The extension of the electric push rod 27 causes the control block 26 to slide upward. The upward sliding of the control block 26 pumps the hydraulic oil in the functional block 24 into the slider 22, so that the slider 23 slides away from the first turntable 6. The sliding of the slider 22 drives the moving plate 30 to slide through the driving rod 29. The sliding of the moving plate 30 reduces the pressure between the first deceleration block 32 and the first turntable 6. The pressure between the second deceleration block 33 and the second turntable 21 increases, thereby reducing the rotational resistance of the first turntable 6 and increasing the rotational resistance of the second turntable 21. The extension length of the electric push rod 27 is controlled by the detector 13, thereby controlling the rotational resistance of the first turntable 6 and the second turntable 21, and reflecting the signal strength of the optical cable. After the rotational resistance of the first turntable 6 is reduced, its rotational speed is increased, thereby increasing the frequency of the hammer block 9 hammering the ground, thereby increasing the detection frequency. The closer to the optical cable, the higher the detection frequency, which avoids invalid testing and further improves the detection accuracy.

[0020] The control mechanism also includes two moving plates 30, which are slidably connected between two opposite inner side walls of the cover body 2. Four sliding rods 31 are slidably connected through the moving plate 30, two of which are fixedly connected to a first deceleration block 32, and the other two sliding rods 31 are fixedly connected to a second deceleration block 33. A plurality of springs 34 are fixedly connected between the first deceleration block 32, the second deceleration block 33 and the moving plate 30. When the cable is approached, the rotation resistance of the second turntable 21 increases, so that the resistance to pushing the device forward increases. The user can clearly feel the increase in the resistance to pushing the device. At this time, continue to push the device. If you feel that the push If the dynamic resistance continues to increase, it means that it is gradually approaching the cable. If the pushing resistance is felt to gradually decrease during the pushing process, it means that it is gradually moving away from the cable. The optical cable signal detected by the detector 13 becomes weaker, causing the electric push rod 27 to retract, thereby reducing the rotation resistance of the second turntable 21. It is necessary to adjust the pushing direction and continue pushing. According to the size of the pushing resistance, the position of the optical cable is adjusted. When it is directly above the optical cable, the extended length of the electric push rod 27 is increased, thereby making the rotation resistance of the second turntable 21 reach the maximum. At this time, when the equipment is pushed, the walking wheel 16 no longer rotates, but slides on the ground, so that the position of the optical cable is accurately known.

[0021] A cleaning mechanism is provided at the cover body 2, and the cleaning mechanism includes two intermediate blocks 35, the intermediate blocks 35 are fixedly connected to the inner top wall of the cover body 2, and the two intermediate blocks 35 are penetrated and slidably connected with a plurality of intermediate rods 36, and the intermediate rods 36 are jointly fixedly connected with a cleaning block 45, and bristles are provided on the upper surface of the cleaning block 45, and one end of the intermediate rod 36 away from the cleaning block 45 is fixedly connected with a top block 37, and the inner top wall of the cover body 2 is rotatably connected with a fourth rotating shaft 38 through a bearing, and the fourth rotating shaft 38 is penetrated and fixedly connected with a second bevel gear 40 and a cam 39, and the second bevel gear 40 is meshed with the corresponding first bevel gear 42, as shown in FIG. Figure 4 As shown, the projections of the two cams 39 are in the same direction. When the two rotate synchronously, the two cams 39 can make the cleaning block 45 reciprocate. When the walking wheel 16 rotates, it will also drive the second rotating shaft 15 to rotate. The rotation of the second rotating shaft 15 drives the first pulley 17 to rotate. The first pulley 17 drives the second pulley 19 to rotate through the synchronous belt 20. The second pulley 19 drives the third rotating shaft 18 to rotate. The third rotating shaft 18 drives the first bevel gear 42 to rotate, thereby rotating the second bevel gear 40 meshing therewith. The second bevel gear 40 drives the fourth rotating shaft 38 to rotate. The rotation of the fourth rotating shaft 38 drives the cam 39 to rotate. By setting the positions of the two cams 39, they alternately push the top block 37 to move, so that the top block 37 drives the cleaning block 45 to reciprocate through the intermediate rod 36, and continuously cleans the surface of the detector 13, thereby preventing impurities on the surface of the detector 13 from affecting the measurement accuracy.

[0022] It is worth mentioning that the cleaning of the surface of the detector 13 does not require power supply from external equipment, making the equipment more energy-efficient.

[0023] The side walls of the first deceleration block 32 and the second deceleration block 33 on the opposite side are both arc surfaces and are glued with damping pads. The center of the arc surface is consistent with the center of the first rotating disk 6 and the second rotating disk 21, that is, they are in contact and completely fitted.

[0024] The two opposite side walls of the cover body 2 are provided with limiting holes 43, and the cover body 2 is slidably connected to the limiting block 44 through the limiting hole 43. The limiting block 44 is fixedly connected to the corresponding side wall of the movable plate 30. Through the cooperation between the limiting hole 43 and the limiting block 44, the sliding of the movable plate 30 is limited so that it can only slide in the horizontal direction, ensuring that its sliding is more stable.

[0025] In the present invention, the handle 4 is held and the walking wheel 16 is brought into contact with the ground to be measured. At this time, the detector 13 and the motor 7 are turned on, and the device is pushed forward. During the pushing process, the motor 7 drives the first turntable 6 to rotate through the first rotating shaft 5, and the rotation of the first turntable 6 drives the fixed rod 8 to rotate, and then through the transmission of the connecting block 12, the hammer block 9 continuously reciprocates up and down to hammer the ground. During the hammering process, information is received through the detector 13, and analyzed and calculated by the remote host to measure the position of the optical cable.

[0026] When the traveling wheel 16 rotates, it also drives the second rotating shaft 15 to rotate. The rotation of the second rotating shaft 15 drives the first pulley 17 to rotate. The first pulley 17 drives the second pulley 19 to rotate through the synchronous belt 20. The second pulley 19 drives the third rotating shaft 18 to rotate. The third rotating shaft 18 drives the first bevel gear 42 to rotate, thereby rotating the second bevel gear 40 meshing therewith. The second bevel gear 40 drives the fourth rotating shaft 38 to rotate. The rotation of the fourth rotating shaft 38 drives the cam 39 to rotate. By setting the positions of the two cams 39, they are alternately pushed to move the top block 37, so that the top block 37 drives the cleaning block 45 to reciprocate through the intermediate rod 36, thereby continuously cleaning the surface of the detector 13.

[0027] During the detection process, when the detector 13 detects that it is close to the position of the optical cable, the PLC control circuit extends the electric push rod 27, and the extension of the electric push rod 27 causes the control block 26 to slide up. The upward sliding of the control block 26 will pump the hydraulic oil in the functional block 24 into the slider 22, thereby causing the slider 23 to slide away from the first turntable 6, and the sliding of the slider 22 will drive the moving plate 30 to slide through the driving rod 29, and the sliding of the moving plate 30 will reduce the pressure between the first deceleration block 32 and the first turntable 6, and at the same time increase the pressure between the second deceleration block 33 and the second turntable 21, thereby reducing the rotation resistance of the first turntable 6 and increasing the rotation resistance of the second turntable 21. After the rotation resistance of the first turntable 6 is reduced, its rotation speed is increased, thereby increasing the frequency of the hammer block 9 hammering the ground, thereby increasing the detection frequency.

[0028] At the same time, when approaching the cable, the rotational resistance of the second turntable 21 increases, which increases the resistance to pushing the device forward. The user can clearly feel the increase in the resistance to pushing the device. At this time, continue to push the device. If you feel that the pushing resistance continues to increase, it means that you are gradually approaching the cable. If you feel that the pushing resistance gradually decreases during the pushing process, it means that you are gradually moving away from the cable. The optical cable signal detected by the detector 13 becomes weaker, thereby causing the electric push rod 27 to retract, and then the rotational resistance of the second turntable 21 becomes smaller. It is necessary to adjust the pushing direction and continue pushing. According to the size of the pushing resistance, the position of the optical cable is adjusted. When it is located directly above the optical cable, the extended length of the electric push rod 27 increases, thereby making the rotational resistance of the second turntable 21 reach the maximum. At this time, when pushing the device, the walking wheel 16 no longer rotates, but slides on the ground, so that the position of the optical cable is accurately known.
