[0005] I. The clamping direction of the weak magnetic detection device is inconsistent with the clamping direction of the magnetic memory planning device. If the clamping direction is found to be inconsistent before the weak magnetic detection device is used, it only needs to be reassembled. However, if the clamping direction is found to be inconsistent when the weak magnetic detection device is used, it is extremely likely to cause the detection result to be invalid, and it may also cause damage to the detection equipment.

[0006] II. During detection, the detection equipment is subjected to knocking, impact, rubbing and various forms of interference. The displacement of the detection equipment caused by external force will cause rubbing between the detection equipment and the steel wire rope, which will also cause the detection result to be invalid and the detection equipment to be damaged.

[0054] Embodiment one:

[0055] Referring to the accompanying drawings Figure 4 and Figure 5 , the magnetic memory planning device 1 is composed of a planning main body 101 and a planning auxiliary body 102, and a directional main part 4 is detachably assembled on the top of the outer wall of the planning main body 101, and the directional main part 4 records the clamping direction of the magnetic memory planning device 1 when the additional magnetic signal is added;

[0056] Referring to the accompanying drawings Figure 7 , a hemispherical cavity is formed in the top of the inside of the directional main part 4, and an observation ball shell 401 is integrally arranged on the top of the hemispherical cavity, an inner compass 403 is rollingly assembled in the inside of the hemispherical cavity, a compass needle 404 is movably assembled on the surface of one side of the inner compass 403, and a shielding piece 405 is integrally arranged on one end of the compass needle 404, and an infrared photoelectric sensor 402 is annularly and arrayedly embedded and installed on the inner wall of the hemispherical cavity, and the infrared photoelectric sensor 402 is used for recording the pointing direction of the compass needle 404 when the inner compass 403 is horizontal.

[0057] Referring to the accompanying drawings Figure 7 , a counterweight 406 is integrally arranged on the side of the inner compass 403 away from the compass needle 404, a pressure sensor 407 is embeddedly installed on the bottom of the inside of the hemispherical cavity, an integrated sensor chip 408 is installed on the bottom of the inside of the directional main part 4, and the integrated sensor chip 408 is electrically connected with the infrared photoelectric sensor 402 and the pressure sensor 407, and a wiring end 409 is embeddedly installed on the inner wall of the directional main part 4, and the wiring end 409 is electrically connected with the integrated sensor chip 408.

[0058] According to the above structure, the inner compass 403 cooperates with the counterweight 406 to adaptively roll in the hemispherical cavity under the action of gravity, when the magnetic memory planning device 1 is clamped in the correct use condition, it is in a horizontal state, and at this time the counterweight 406 will be in contact with the pressure sensor 407, the inner compass 403 is in a horizontal state, and by virtue of the pointing direction of the compass needle 404, no matter in which direction the magnetic memory planning device 1 is used, the infrared photoelectric sensor 402 in a certain direction will be blocked by the shielding piece 405 on one end of the compass needle 404, and the position information of the blocked infrared photoelectric sensor 402 will be recorded, finally, only when the pointing information is recorded successfully, the magnetic work of the magnetic memory planning device 1 can be started again, so as to avoid the influence of the magnetic process on the pointing process of the compass needle 404.

[0059] Referring to the drawings Figure 5 And Figure 6 , the weak magnetic detection device 2 is composed of a detection main body 201 and a detection auxiliary body 202, and the top of the outer wall of the detection main body 201 is detachably assembled with a directional auxiliary part 5, and the directional auxiliary part 5 verifies whether the clamping direction of the weak magnetic detection device 2 and the magnetic memory planning device 1 is consistent.

[0060] Referring to the drawings Figure 6 , the internal structure of the directional auxiliary part 5 is the same as that of the directional main part 4, and the outer wall of the directional auxiliary part 5 is fixedly installed with a prompt light 501, and the prompt light 501 is electrically connected with the chip arranged in the directional auxiliary part 5.

[0061] According to the above structure, the directional auxiliary part 5 at the top of the detection main body 201 has the same internal structure as the directional main part 4, when the weak magnetic detection device 2 is determined to be in a horizontal state, according to the infrared photoelectric sensor 402 in the directional auxiliary part 5 which is finally blocked by the shielding piece 405, the position information is compared with the position information recorded in advance by the directional main part 4, when the two pointing information is the same, it indicates that the clamping direction of the magnetic memory planning device 1 and the weak magnetic detection device 2 is the same, then the weak magnetic detection device 2 can be finally fixed, when the two pointing information is different by 180° (according to the actual detection condition, generally only the same or different by 180° two conditions), it indicates that the clamping direction of the magnetic memory planning device 1 and the weak magnetic detection device 2 is opposite, then the prompt light 501 starts to flash;

[0062] According to the above content, through the cooperation of the directional main part 4 and the directional auxiliary part 5, with the help of direction verification and the flashing prompt of the prompt light 501, it can be verified whether the clamping direction of the weak magnetic detection device 2 and the magnetic memory planning device 1 is consistent, which can avoid the error operation of the weak magnetic detection device 2 in the existing electromagnetic detection process, and further avoid the invalid detection result and the damage of the detection equipment.

[0063] The working principle of the application is: in the process of electromagnetic detection by using the magnetic memory planning device 1 and the weak magnetic detection device 2, it is necessary to ensure that the clamping direction of the magnetic memory planning device 1 and the weak magnetic detection device 2 is the same, so as to ensure that the detection result will not be invalid, and avoid the damage of the detection equipment;

[0064] Before the magnetic memory planning device 1 is installed, the battery inside the planning body 101 powers the integrated sensor chip 408 in advance. The pressure sensor 407 is used to detect whether its surface is under pressure, that is, the counterweight 406 is in contact with the pressure sensor 407, which is condition one. In addition, a certain infrared photoelectric sensor 402 distributed in the array is blocked by the shielding plate 405 at one end of the compass 404, which is condition two. When the above two conditions are met at the same time, it can be determined that the magnetic memory planning device 1 is in a horizontal state. With the help of the compass 404's pointing characteristic, according to the infrared photoelectric sensor 402 that is finally blocked by the shielding plate 405, its position is determined to represent the direction of the planning body 101 when the magnetic memory planning device 1 completes the card installation. This pointing information is transmitted to the computer via Bluetooth or other wireless transmission methods.

[0065] Next, when installing the weak magnetic field detection device 2, the internal structure of the directional sub-component 5 on the top of the detection body 201 is the same as that of the directional main component 4. When the weak magnetic field detection device 2 is determined to be in a horizontal state, the position of the infrared photoelectric sensor 402, which is ultimately blocked by the blocking plate 405 inside the directional sub-component 5, is determined to represent the direction of the detection body 201 when the weak magnetic field detection device 2 has completed installation. This direction information is transmitted to the computer via wired or wireless transmission and compared with the previously pre-input direction information of the planning body 101. When the two direction information are the same, it means that the installation direction of the magnetic memory planning device 1 and the weak magnetic field detection device 2 is the same, which is the correct usage. However, when the two direction information are opposite, it means that the installation direction of the magnetic memory planning device 1 and the weak magnetic field detection device 2 is opposite, which is the incorrect usage. At the same time, the indicator light 501 flashes to remind the operator to adjust the installation direction of the weak magnetic field detection device 2 in time before starting the detection.

[0066] Example 2:

[0067] See attached document Figure 4 , Figure 5 and Figure 6 The magnetic memory planning device 1 and the weak magnetic detection device 2 are respectively assembled with a first resistance protection component 6 and a second resistance protection component 7 by screws on their outer sides. The first resistance protection component 6 is used to stabilize the mounting position of the magnetic memory planning device 1 when it is working and to clean the steel wire rope 3 at the same time. The second resistance protection component 7 has a similar structure and the same function as the first resistance protection component 6.

[0068] See attached document Figure 8 and Figure 9 The resistance protection component 6 includes a back frame 601 that is installed on the outer wall of the main body 101 and the sub-body 102 by screws, and a force frame 614 that is rotatably assembled at the top and bottom ends of the back frame 601.

[0069] See attached document Figure 9, two hollow frames 602 are integrally arranged on the two sides of the outer wall of the back frame 601, the middle parts of the two hollow frames 602 are commonly connected with a circular frame 603, the middle parts of the two hollow frames 602 are integrally arranged with horizontal guide sleeves 607, a rotating wheel 604 is rotatably assembled in the inner wall of the circular frame 603, an arm 605 is pivotally connected to the inner wall edge of the rotating wheel 604 in a point-symmetrical manner, bidirectional toothed rods 606 are movably assembled in the interiors of the two hollow frames 602, and the rod bodies of the bidirectional toothed rods 606 at the middle positions are slidably connected with the corresponding horizontal guide sleeves 607, the directions of the inclined teeth at the two ends of the bidirectional toothed rods 606 are opposite, and the ends of the two arms 605 are respectively connected with the rod bodies of the bidirectional toothed rods 606 at the middle positions;

[0070] Referring to the accompanying drawings Figure 9 and Figure 10 , the top and bottom ends in the interiors of the hollow frames 602 are slidably assembled with sliding blocks one 608, the interiors of the sliding blocks one 608 are elastically and telescopically assembled with toothed blocks 609 through springs one 610, the toothed blocks 609 are engaged with the inclined teeth at the corresponding ends of the bidirectional toothed rods 606, the sides, away from each other, of the two sliding blocks one 608 in the same hollow frame 602 are elastically connected with sliding blocks two 612 through springs two 611, and the sliding blocks two 612 are also slidably assembled in the interiors of the hollow frames 602, the interiors of the sliding blocks two 612 are all penetrated with perforations 613.

[0071] Referring to the accompanying drawings Figure 11 , the two ends of one side of the force frame 614 are integrally arranged with rotating core rods 615 which are rotatably connected with the back frame 601, the ends of the arm rods 616 are integrally arranged near the ends of the rotating core rods 615, the ends of the arm rods 616 are inserted into the interiors of the perforations 613 of the adjacent sliding blocks two 612, the side of the force frame 614 which is in contact with the steel wire rope 3 is fixedly installed with a hollow groove shaft 617, and the outer surface of the hollow groove shaft 617 is rotatably sleeved with a groove sleeve 619 which is used to directly contact with the steel wire rope 3.

[0072] According to the above structure, before the magnetic memory planning device 1 is used, the resistance protection piece one 6 is symmetrically installed on the outer walls of the planning main body 101 and the planning auxiliary body 102, after the magnetic memory planning device 1 is finally clamped, as shown in the accompanying drawings Figure 1 and Figure 2As shown, the two sets of groove sleeves 619 at the top and bottom ends clamp the steel wire rope 3 at the same time. To avoid the groove sleeves 619 giving the steel wire rope 3 excessive clamping force, the corresponding side rotating wheel 604 is rotated at this time, and the two double-direction toothed rods 606 on the same side are pulled close to each other through the two connecting arms 605, at which time the toothed blocks 609 will be separated from the double-direction toothed rods 606 and in a free state. According to the elastic force of the spring two 611, the position of the sliding block one 608 is self-adaptively adjusted, so as to finally ensure that the groove sleeves 619 only fit the steel wire rope 3 and do not give excessive clamping force. Then the rotating wheel 604 is reversed to make the double-direction toothed rods 606 re-engage with the corresponding toothed blocks 609, and the final position of each sliding block one 608 is fixed. At this time, all the preparations before use of the magnetic memory planning device 1 are completed. In addition, the preparations of the weak magnetic detection device 2 and the resistance protection piece two 7 are the same as above.

[0073] In use of the magnetic memory planning device 1, as shown in the attached Figure 14 As shown, when the magnetic memory planning device 1 is deviated by L1 due to sudden external force, since the steel wire rope 3 is connected with weights at both ends in use, the steel wire rope 3 itself has a certain tension, and the steel wire rope 3 will give a lateral compressive stress F1 to the groove sleeve 619 fitted therewith. Under the action of this stress, the force frame 614 will rotate with the rotating shaft 615 as the center, i.e. L2. When the rotating shaft 615 is pre-rotated, the sliding block two 612 at the end of the arm rod 616 has a tendency to move downward. Since the position of the sliding block one 608 is fixed, the spring two 611 at this time will give the sliding block two 612 a reverse resistance F2, which hinders the rotation of the force frame 614 and indirectly resists the external force acting on the magnetic memory planning device 1, so as to realize the resistance to the shaking of the magnetic memory planning device 1 caused by external force, and realize the reduction of the influence of the detection equipment caused by knocking, impact, rubbing and various forms of interference. The action of the resistance protection piece two 7 on the weak magnetic detection device 2 is the same as above.

[0074] Referring to the attached Figure 11 and Figure 12 The inner wall of each groove of the hollow groove shaft 617 near the side of the steel wire rope 3 is linearly arrayed with air holes one 618, the inner wall of each groove of the groove sleeve 619 near the side of the steel wire rope 3 is slidingly ring-shaped arrayed with air holes two 620, and the air holes one 618 are only communicated with part of the air holes two 620.

[0075] Referring to the attached Figures 11-13, the two ends of the slot sleeve 619 are fixedly installed with gear one 621, the force frame 614 is rotatably assembled with a transmission shaft 622 on one side of the two ends of the hollow slot shaft 617, and one end of the transmission shaft 622 is installed with gear two 623 engaged with gear one 621, both ends of the force frame 614 are rotatably assembled with a gas force shaft 624, and one end of the gas force shaft 624 is drivingly connected with the transmission shaft 622 through a sleeved synchronous belt 625, and the middle part of the gas force shaft 624 is integrally provided with a swash plate 626.

[0076] Referring to the drawings Figures 11-13 , the two ends of the gas force shaft 624 are fixedly installed with an air injector 627 and a gas storage pipe 631, the inside of one end of the air injector 627 is telescopically assembled with a gas plug 628, and the outside of the same end of the air injector 627 is provided with a spring three 629 in a compressed state, the same end of the air injector 627 and the inside of the gas plug 628 are jointly attached to the corresponding swash plate 626, the other end of the air injector 627 away from the spring three 629 is connected with an air injection pipe 630 and an air inlet pipe, and the inside of the air injection pipe 630 and the air inlet pipe is assembled with a one-way valve;

[0077] Referring to the drawings Figures 11-13 , the inside of the gas storage pipe 631 is elastically movably assembled with a gas plug 633 through a spring four 632 arranged at one end, and the spring four 632 is also in a compressed state, the other end of the gas storage pipe 631 away from the gas plug 633 is connected with an air outlet pipe 634, and the distal end of the air outlet pipe 634 is connected with one end of the hollow slot shaft 617, the distal end of the air injection pipe 630 is connected with the other end of the gas storage pipe 631 away from the gas plug 633.

[0078] According to the above structure, in the process of the steel wire rope 3 passing through the magnetic memory planning device 1, the slot sleeve 619 attached thereto will rotate, the gear one 621 at one end of the slot sleeve 619 is engaged with the gear two 623, causing the transmission shaft 622 to rotate, the transmission shaft 622 drives the gas force shaft 624 to rotate at the same time through the synchronous belt 625, at the same time, the swash plate 626 rotates, under the action of the spring three 629, the gas plug 628 in contact with the swash plate 626 will continuously expand and contract in the corresponding air injector 627, the air injector 627 can continuously inject air into the gas storage pipe 631, the internal pressure of the gas storage pipe 631 rises and the gas plug 633 continuously moves and presses the spring four 632;

[0079] When the air hole one 618 coincides with part of the air hole two 620 during the rotation of the slot sleeve 619, the gas in the gas storage pipe 631 will quickly enter the hollow slot shaft 617 through the air outlet pipe 634 under the action of the spring four 632, and finally be sprayed to the steel wire rope 3 through the air hole one 618, so as to remove the impurities attached to the surface of the steel wire rope 3, in addition, the effect of the resistance protection piece two 7 is the same as above;

[0080] The above-mentioned process allows for the temporary storage of a certain pressure of gas in the gas storage pipe 631 during the process of the steel wire rope 3 passing through the detection device. When the gas hole 618 overlaps with part of the gas hole 620, the gas is quickly ejected. This powerful airflow is used to clean the impurities on the surface of the steel wire rope 3. The entire process is automatic and requires no equipment investment.

[0081] The working principle of this invention is as follows: When the magnetic memory planning device 1 is used, as shown in the attached... Figure 14 As shown, when the magnetic memory planning device 1 deviates by L1 due to a sudden external force, since the steel wire rope 3 is connected to heavy objects at both ends during use, the steel wire rope 3 itself has a certain tension. The steel wire rope 3 will give the groove sleeve 619 that it is in contact with a lateral compressive stress F1. Under the action of this stress, the force frame 614 will be driven to rotate around the rotating rod 615 as the central axis, i.e., L2. When the rotating rod 615 is about to rotate, the slider 612 at the end of the arm 616 has a tendency to move downward. Since the position of the slider 608 is fixed, the spring 611 will give the slider 612 a reverse resistance force F2. With the help of this resistance force F2, the force frame 614 is hindered from rotating, which indirectly resists the external force acting on the magnetic memory planning device 1, thereby resisting the shaking of the magnetic memory planning device 1 caused by the external force, and reducing the impact of the detection equipment being hit, impacted, rubbed and various forms of interference. The function of the resistance protection component 7 on the weak magnetic detection device 2 is the same as above.

[0082] As the steel wire rope 3 passes through the magnetic memory planning device 1, the slotted sleeve 619 that is in contact with it will rotate. Gear 621 and gear 623 at one end of the slotted sleeve 619 mesh, causing the drive shaft 622 to rotate. The drive shaft 622, in turn, drives the pneumatic shaft 624 to rotate simultaneously via the synchronous belt 625. At the same time, the swashplate 626 rotates on its own axis. Under the action of the spring 629, the air plug 628 that is in contact with the swashplate 626 will continuously extend and retract inside the corresponding air injector 627. The air injector 627 can continuously inject air into the air storage pipe 631, the air pressure inside the air storage pipe 631 increases and the air plug 633 moves continuously and squeezes the spring 632; when the slot sleeve 619 rotates, when the first air hole 618 coincides with part of the second air hole 620, the gas inside the air storage pipe 631 will be quickly discharged from the air pipe 634 and enter the hollow slot shaft 617 under the action of the spring 632, and finally sprayed onto the wire rope 3 through the first air hole 618, thereby removing the impurities attached to the surface of the wire rope 3.
