Description

Technical Field

[0001] The present invention relates to the technical field of steel wire rope static tension detection, and in particular to a steel wire rope static tension detection mechanism and a detection device thereof. Background Art

[0002] According to GB16423-2020, "Safety Regulations for Metal and Non-metal Mines," hoist wire rope tension must be checked weekly during actual mining operations, and the time difference between the rebound waves of the tension of each rope must not exceed 10%. If this range is exceeded, there is a safety hazard and the wire rope needs to be replaced.

[0003] The purpose of the above-mentioned test is to ensure that the static tension of multiple steel wire ropes is basically the same. However, in reality, the static tension of the steel wire rope cannot be measured directly, and it is mainly measured indirectly by measuring the rebound wave time. The principle is that when the suspension length of the same type of steel wire rope is the same, its oscillation frequency is proportional to the tension. Chinese patent application No. 2022226636032 discloses a mobile elastic wave detection device, which includes a steel wire rope distance adjustment mechanism, a self-locking unhooking mechanism for the steel wire rope to generate oscillations, and a follow-up conversion mechanism for obtaining the steel wire rope oscillation wave data. The linear displacement of the follower rod in the follow-up conversion mechanism is converted into rotational motion through a set of gear rack mechanisms, and then detected by using the angle measurement function of the sensor.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] like Figure 14 and Figure 18 As shown, the present invention provides a wire rope static tension detection device, which includes a lower sponge box body 1 and an upper sponge cover plate 2. A plurality of placement cavities are provided inside the lower sponge box body 1, and a detection host 100, a telescopic push rod 200 and a data processing terminal 3 are respectively placed in the plurality of placement cavities. The data processing terminal 3 and the detection host 100 can be electrically connected or wirelessly connected to realize signal transmission between the data processing terminal 3 and the detection host 100.

[0055] The detection host 100 is connected to the wire rope 300 in a stationary state at the wellhead through the telescopic push rod 200, and the wire rope 300 is pushed by the telescopic push rod 200 to generate vibration for detection. When pushing the wire rope 300, it should be ensured that the vibration amplitude of the wire rope 300 is less than 100 mm. Then, the data processing terminal 3 processes the detection data to obtain the required parameters (rebound wave time difference and static tension difference).

[0056] Example 1

[0057] like Figures 1-4 As shown, this embodiment provides a wire rope static tension detection mechanism, which includes a detection host 100 and a telescopic push rod 200;

[0058] The above-mentioned detection host 100 includes an instrument box 110, a winding wheel assembly 150 is provided on one side of the instrument box 110, and a winding wheel assembly 160 is provided on the other side. A pull rope 130 is wound around the winding wheel assembly 150, wherein the free end of the pull rope 130 passes around the winding wheel assembly 160 and extends out of the instrument box 110 to be connected to a hook assembly 120, and the hook assembly 120 is located at the outer end of the instrument box 110. An instrument box panel 170 is installed on the top of the instrument box 110, and a magnetic detection assembly 140 is provided on the instrument box panel 170 near the side of the winding wheel assembly 150, and the winding wheel assembly 160 is arranged through the above-mentioned instrument box panel 170;

[0059] It should be noted that the magnetic detection component 140 is used to detect magnetic field change data. The specific structure, control logic, and signal output and processing of the magnetic detection component 140 are all existing technologies. The following is an explanation with a specific example. The magnetic detection component 140 may include a sensor and a rechargeable battery. The rechargeable battery provides power to the sensor, detects magnetic field change data through the sensor, and transmits the data to the data processing terminal 3 for processing. The sensor may be a Hall sensor, etc.

[0060] Furthermore, if Figure 6 As shown, a magnet seat 180 is further provided on the bottom surface of the instrument box panel 170, and the magnet seat 180 is linked with the winding wheel assembly 160;

[0061] The linear motion of the pull rope 130 on the outside of the instrument box 110 is converted into rotational motion through the winding wheel assembly 150 and the reel assembly 160, and then converted into linear motion of the magnet base 180 (wherein the linear motion direction of the magnet base 180 is perpendicular to the linear motion direction of the pull rope 130 on the outside of the instrument box 110). The magnetic detection assembly 140 detects the magnetic field change data when the magnet base 180 moves, and transmits the data to the data processing terminal 3 for processing.

[0062] In this embodiment, a pull rope 130, a winding wheel assembly 150, a reel assembly 160 and a magnet seat 180 are provided for motion conversion, so that the linear motion of the pull rope 130 is converted into the motion of the internal magnet seat 180, thereby optimizing the detection structure (no rigid rod structure movement is required), further reducing the size of the detection host 100, reducing the installation space requirement, and being more adaptable and capable of accurate and precise measurement.

[0063] Preferably, the winding wheel assembly 150 and the reel assembly 160 are horizontally arranged along the length direction of the instrument box 110, so that the pull rope 130 can be wound from the winding wheel assembly 150 to the reel assembly 160 more smoothly.

[0064] Preferably, if Figure 5 As shown, the above-mentioned instrument box 110 includes an instrument box body 111. The size of the instrument box body 111 determines the external dimensions of the entire detection host 100. On the basis of realizing the detection function, the instrument box body 111 in this embodiment is preferably smaller in size to further enhance the adaptability on complex wellhead platforms, and a mounting structure is provided at the bottom of the instrument box body 111 for installation at the wellhead. The specific structure of the mounting structure is not limited, and a magnetic mounting structure or a fixed mounting structure such as bolts can be adopted.

[0065] A first mounting groove 113 is provided on one side of the instrument box body 111, and a second mounting groove 116 is provided on the other side. The first mounting groove 113 and the second mounting groove 116 are arranged horizontally along the length direction of the instrument box body 111, and there are air escape grooves 117 between the first mounting groove 113 and the side wall of the instrument box body 111, between the second mounting groove 116 and the side wall of the instrument box body 111, and between the first mounting groove 113 and the second mounting groove 116. This reduces weight while increasing operating space and prevents interference between the movement of the winding wheel assembly 150 and the winding wheel assembly 160 inside the instrument box body 111.

[0066] In order to reduce the friction between the pull rope 130 wound on the winding wheel assembly 150 and the winding wheel assembly 160 and the instrument box body 111, a wire accommodating groove 114 is opened on the axial surface of the first installation groove 113 and the second installation groove 116 corresponding to the winding space of the pull rope 130, thereby increasing the accommodating space, reducing the influence of friction, and thereby improving the detection accuracy.

[0067] More specifically, a positioning column 115 is provided on the mounting platform along one side of the length direction inside the instrument box body 111. The positioning column 115 is used for positioning and assembling with the instrument box panel 170, and a retention groove 112 is also provided on the instrument box body 111. The retention groove 112 is connected to the outside world and is used to limit the storage of the hook assembly 120 during non-use periods.

[0068] Preferably, if Figure 6 As shown, in this embodiment, the instrument box panel 170 includes a through hole 1 corresponding to the winding wheel assembly 150 and a through hole 2 corresponding to the position of the winding wheel assembly 160, wherein the winding wheel assembly 160 is arranged through the through hole 2, and a linear groove 171 is provided between the through hole 1 and the through hole 2, and the above-mentioned magnet base 180 is slidably provided in the linear groove 171. The linear groove 171 limits the movement of the magnet base 180, so that the rotational motion of the winding wheel assembly 160 is converted into the linear motion of the magnet base 180.

[0069] It should be further explained that a protective film layer is attached to the top of the instrument box panel 170, and corresponding identification texts, including "test position", are engraved on the protective film layer to serve as a reminder, such as Figure 1 As shown, the protective film layer is the prior art.

[0070] Preferably, if Figure 4 、 Figure 7-Figure 9 As shown, in this embodiment, the winding wheel assembly 150 includes a first rotating shaft 151, which is installed in the first mounting groove 113, and a winding wheel 152 and a cylindrical gear 153 are rotatably provided on the first rotating shaft 151, wherein the cylindrical gear 153 is located on the upper side of the winding wheel 152, and one end of the pull rope 130 in this embodiment is fixed on the winding wheel 152 and wrapped around the axial surface of the winding wheel 152, and a torsion spring is connected between the winding wheel 152 and the cylindrical gear 153, so that the winding wheel 152 can be rotated and reset during the detection process, and a ratchet 159 is provided on the mounting platform along the length direction of the instrument box body 111, and the ratchet 159 limits the cylindrical gear 153. On the one hand, when the winding wheel 152 is rotated under force, a stable torsion spring base fulcrum is provided, and on the other hand, when the pull rope 130 is wound, the winding degree can be flexibly adjusted to prevent the pull rope 130 from slackening and hooking with the internal structure, affecting operation.

[0071] Preferably, if Figure 4 、 Figure 10-12As shown, the winding wheel assembly 160 in this embodiment includes a second rotating shaft 161, which is installed in the second installation groove 116, and a winding wheel 162 is rotatably provided on the second rotating shaft 161, and a knob 163 is installed on the top of the winding wheel 162, and the knob 163 is set on the outer side of the instrument box panel 170. The pull rope 130 extending from the winding wheel 152 is wound around the winding wheel 162 and is set through the instrument box body 111.

[0072] Furthermore, the reel assembly 160 is further provided with a linkage member to realize the linkage between the reel assembly 160 and the magnet seat 180. The linkage member includes a sliding groove 164 provided on the top surface of the reel 162. The sliding groove 164 is eccentrically arranged. Specifically, the center of the sliding groove 164 is biased toward the side of the winding wheel 152 during installation. A connecting shaft is slidably provided in the sliding groove 164. The connecting shaft is connected to one end of the magnet seat 180, so that the magnet seat 180 is movably arranged in the eccentric sliding groove 164.

[0073] When the pull rope 130 drives the winding wheel 162 to rotate, the rotating sliding groove 164 drives the magnet seat 180 to move linearly along the length direction of the detection host 100 through the connecting shaft to realize data detection.

[0074] Preferably, if Figure 1 As shown, in this embodiment, the free end of the pull rope 130 extending from the instrument box body 111 is connected to the hook assembly 120, wherein the hook assembly 120 includes a hook body 121, and a clamping platform 122 is provided at the tail of the hook body 121. The clamping platform 122 is used to position the hook body 121 when it is pulled out by the telescopic push rod 200.

[0075] Preferably, if Figure 13 As shown, a sliding boss 181 is provided on the top surface of the magnet seat 180 in this embodiment, and the sliding boss 181 is adapted to the linear groove 171 of the instrument box panel 170 to limit the linear motion of the magnet seat 180, and an assembly hole 183 is provided at the tail of the magnet seat 180, and the assembly hole 183 is connected to the connecting shaft of the linkage member, and the magnet seat 180 is connected to the sliding groove 164 through the connecting shaft, so that the sliding groove 164 rotates to drive the magnet seat 180 to move linearly, and a magnet mounting groove 182 is provided at the head of the magnet seat 180, and a permanent magnet is installed in the magnet mounting groove 182. During the movement of the magnet seat 180, the magnetic field change data of the magnet seat 180 when it moves is measured by the magnetic detection component 140, and the magnetic field measurement function of the magnetic detection component 140 is used to directly measure the displacement of the pull rope 130, thereby measuring the time between the two peaks.

[0076] It should be noted that directly measuring displacement using the magnetic field measurement function of the magnetic detection component 140 is an existing technology, and the specific principle will not be elaborated here.

[0077] During operation, the hook assembly 120 is hung on a steel wire rope 300 to be tested through the telescopic push rod 200, so that the pull rope 130 is in a horizontal state, and the rotary knob 163 points to the test position. Then, the steel wire rope 300 is pushed by the telescopic push rod 200 to vibrate, ensuring that the vibration amplitude of the steel wire rope 300 is less than 100 mm. The vibrating steel wire rope 300 will drive the pull rope 130 to move in a straight line, and the pull rope 130 drives the winding wheel 152 and the winding wheel 162 to rotate. The rotating winding wheel 162 drives the magnet seat 180 to move in a straight line, realizing the conversion from the linear motion of the pull rope 130 to the linear motion of the magnet seat 180. The magnetic field change data of the magnet seat 180 when it moves is measured by the magnetic detection assembly 140 and transmitted to the data processing terminal 3 for processing to obtain the detection results.

[0078] It should be noted that the processing process and logic of the data processing terminal 3 are existing technologies and will not be described in detail here.

[0079] Example 2

[0080] It should be understood that when the winding wheel 152 or the winding wheel 162 is rotated by force, since the direction of the force is not always in the middle of the winding wheel 152 or the winding wheel 162, the winding wheel 152 is prone to fluctuate up and down when rotating around the first rotation axis 151 or the winding wheel 162 is rotating around the second rotation axis 161. If there is an assembly error between the two, the fluctuation will be further amplified, thereby affecting the accuracy of the detection.

[0081] On the basis of Example 1, in order to optimize the up and down fluctuations during the rotation of the winding wheel 152, this embodiment provides a limiting component at the top of the first rotating shaft 151, and the winding wheel 152 and the cylindrical gear 153 are pressed down by the limiting component to avoid fluctuations. The limiting component can be a nut, and a thread is opened at the top of the first rotating shaft 151, and the nut is screwed on for limiting. The limiting component can also be the instrument box panel 170 for direct limiting.

[0082] By squeezing the winding wheel 152 from top to bottom, it is ensured that the winding wheel 152 rotates horizontally to avoid up and down fluctuations.

[0083] Furthermore, when the winding wheel 152 is subjected to downward pressure, it is easy to generate friction with the bottom of the first mounting groove 113, and the generated friction force will affect the detection accuracy. In view of this, this embodiment is provided with a first ball bracket 154 at the bottom of the winding wheel 152, and a plurality of balls are provided in the first ball bracket 154. Rolling friction is used instead of sliding friction to reduce the friction between the winding wheel 152 and the bottom of the first mounting groove 113.

[0084] In addition, first washers 155 are symmetrically arranged on the upper and lower sides of the first ball bracket 154, wherein the first washer 155 on the upper side contacts the bottom surface of the winding wheel 152, and the first washer 155 on the lower side contacts the bottom of the first mounting groove 113. The first washer 155 can be made of steel. The rigid first washer 155 separates the ball in the first ball bracket 154 from the winding wheel 152 and the bottom of the first mounting groove 113. On the one hand, it avoids direct contact between the ball and the winding wheel 152, thereby reducing the wear of the winding wheel 152 (if the ball directly contacts the winding wheel 152, the winding wheel 152 will be worn due to the friction of the ball during long-term movement). On the other hand, under the downward pressure state, the ball and the first washers 155 on both sides roll and rub against each other, thereby reducing the friction force on the winding wheel 152 during movement, making the winding wheel 152 more flexible and improving the detection accuracy.

[0085] Preferably, if Figure 8 and Figure 9 As shown, a mounting groove is provided in the middle of the upper end of the winding wheel 152 in this embodiment, a supporting circular platform 1521 is provided in the mounting circular groove, and an assembly platform 1531 is provided in the middle of the ground of the cylindrical gear 153. The assembly platform 1531 is arranged in conjunction with the supporting circular platform 1521, and a mounting opening is provided on the outer axial surface of the assembly platform 1531, and a mounting opening is also provided on the axial surface of the mounting circular groove. The two mounting openings are used to connect the two ends of the torsion spring to ensure that the torsion spring plays a reset role when the winding wheel 152 rotates.

[0086] Furthermore, in order to ensure the stability of the torsion spring in the upper and lower directions during movement, multiple sets of limit bars 1532 are distributed on the bottom surface of the cylindrical gear 153 around the circumference of the assembly table 1531. The limit bars 1532 limit the upper side of the torsion spring, thereby preventing the torsion spring from moving off and affecting the rotation of the winding wheel 152.

[0087] Further preferably, a second ball bracket 156 is similarly provided between the assembly platform 1531 and the supporting truncated platform 1521, a plurality of balls are provided in the second ball bracket 156, and second washers 157 are symmetrically provided on both sides of the second ball bracket 156, for reducing the wear between the winding wheel 152 and the cylindrical gear 153, and reducing the friction force exerted on the winding wheel 152 during movement.

[0088] Similarly, a third ball bracket 158 ​​is provided on the top surface of the cylindrical gear 153. The third ball bracket 158 ​​is limited on the first rotating shaft 151 by a limiting assembly. Multiple groups of balls are provided in the third ball bracket 158 ​​to facilitate driving when adjusting the cylindrical gear 153.

[0089] In addition, in this embodiment, the third ball bracket 158, the second ball bracket 156 and the first ball bracket 154 fully support the winding wheel 152 and the cylindrical gear 153 to ensure the stability of the movement of the two.

[0090] Preferably, if Figure 9 As shown, in this embodiment, a fixing groove 1522 is provided on one side of the top outer edge of the winding wheel 152 for fixing one end of the pull rope 130 so that the pull rope 130 can be stably wound on the winding wheel 152.

[0091] Furthermore, if Figure 4 As shown, the specific description of the installation structure of the pawl 159 in this embodiment is as follows:

[0092] A pawl 159 is installed on the mounting platform on one side of the instrument box body 111 along the length direction through a pin. One end of the pawl 159 cooperates with the tooth groove of the cylindrical gear 153, and the other end is connected to a tension spring 1510. The other end of the tension spring 1510 is connected to the pull column fixed on the mounting platform. The pawl 159 is engaged with the cylindrical gear 153 to limit the rotation of the cylindrical gear 153 on the winding wheel 152, thereby providing a stable torsion spring fulcrum. When the tightening degree of the pull rope 130 needs to be adjusted, the pawl 159 is manually moved to rotate the cylindrical gear 153, and then the pawl 159 is released to limit the cylindrical gear 153.

[0093] Preferably, if Figure 10-12 As shown, on the basis of embodiment one, in order to optimize the up and down fluctuations of the winding wheel 162 during rotation, this embodiment is provided with a knob 163 on the top of the winding wheel 162, and the knob 163 cooperates with the second rotating shaft 161 to limit the downward pressure of the winding wheel 162, thereby avoiding fluctuations; the instrument box panel 170 can also be used for direct limitation.

[0094] More specifically, a cover plate 1631 is provided on the top of the knob 163, and an "alignment test position" mark is engraved on the cover plate 1631 to facilitate alignment by users. Furthermore, an alignment protrusion 165 is provided on the knob 163 for alignment verification.

[0095] During the test preparation stage, align the alignment protrusion 165 of the knob 163 with the "test position" mark on the top of the instrument box panel 170, so that the sliding slot 164 drives the magnet seat 180 to the set test initial position (due to the initial use of the equipment, the rotation position of the winding wheel 162 is affected by the position of the pull rope 130, causing the permanent magnet in the magnet seat 180 and the magnetic detection component 140 to be offset).

[0096] By squeezing the reel 162 from top to bottom, the reel 162 is rotated horizontally to avoid up and down fluctuations.

[0097] Furthermore, when the winding wheel 162 is subjected to downward pressure, it is easy to generate friction with the bottom of the second mounting groove 116, and the generated friction force will affect the detection accuracy. In view of this, this embodiment is provided with a fourth ball bracket 166 at the bottom of the winding wheel 162, and fourth washers 167 are symmetrically provided at both ends of the fourth ball bracket 166. The fourth ball bracket 166 is used to reduce the friction between the winding wheel 162 and the bottom of the second mounting groove 116, and the fourth washer 167 is combined to separate the winding wheel 162 from the ball, thereby avoiding direct contact between the ball and the winding wheel 162, thereby reducing the wear of the winding wheel 162.

[0098] Furthermore, a mounting platform 1621 is provided on the top of the winding wheel 162, and the mounting platform 1621 is adapted to the mounting groove opened at the bottom of the knob 163, and a fifth ball bracket 168 is also provided on the winding wheel 162. The fifth ball bracket 168 and the fourth ball bracket 166 provide sufficient support to ensure the stability and sensitivity of the movement of the winding wheel 162, thereby improving the accuracy of detection.

[0099] Example 3

[0100] Preferably, if Figure 15-17 As shown, on the basis of Example 1 or Example 2, the telescopic push rod 200 in this embodiment includes a telescopic rod body 201, which is arranged in multiple sections and can be extended and retracted in multiple sections. A push plate 202 is connected to the head of the telescopic rod body 201, and a push platform 203 is provided in the middle of the push plate 202. The outer side of the push platform 203 is arranged in an arc shape, and hanging grooves 204 are symmetrically provided on both sides of the push plate 202. An opening 205 is opened on the side of the hanging groove 204 away from the push platform 203, and a limiting step 206 is provided at the bottom of the hanging groove 204;

[0101] When working, the clamping platform 122 of the hook assembly 120 is inserted into the hanging groove 204 on one side, and the pull rope 130 passes through the opening 205 without causing bending. Then the telescopic rod body 201 is extended to drive the hook body 121 to hang with the wire rope 300, and then the telescopic push rod 200 is retracted to move the clamping platform 122 out of the hanging groove 204, and the wire rope 300 is pushed by the push platform 203 of the telescopic push rod 200 for testing.

[0102] The above invention can be used for detecting the static tension of the steel wire rope of the friction hoist in a coal mine.
