Description

Technical Field

[0001] This invention relates to the field of online monitoring device technology, specifically to an online monitoring device for hydraulic gate hoists and its usage method. Background Technology

[0002] Online monitoring devices can track the operating status of equipment in real time and provide timely warnings of potential faults, which is crucial for ensuring the safety of water conservancy project equipment. As an important online monitoring device, the electromagnetic wire rope flaw detector can accurately detect defects such as broken wires and wear in the wire ropes of water conservancy hoists, helping to maintain them in a timely manner, avoid hoist operation accidents, and ensure the stability of water conservancy projects.

[0003] Currently, existing electromagnetic wire rope flaw detectors require workers to connect the detector and display screen using wires, making automatic connection impossible. Furthermore, when installing the wire rope into the detector, clips are needed to secure it, again failing to achieve automatic connection. This increases the workload for workers and significantly reduces testing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an online monitoring device for hydraulic gate hoists and its usage method, so as to solve the problems mentioned in the background art.

[0006] The automatic connection mechanism includes a second detection device and two sets of support plates. The bottom surface of the second detection device is movably hinged to the upper surface of the first detection device. Each set of support plates consists of two plates. The outer surfaces of the two sets of support plates are respectively fixedly connected to the outer surfaces of the first and second detection devices. The inner walls of the two support plates are rotatably connected to two spiral cylinders. Each spiral cylinder has a spiral shaft slidably connected inside. The outer surface of each spiral cylinder is fixedly connected to a transmission gear. The outer surface of each transmission gear is meshed with a transmission tooth plate. The front sides of the two transmission tooth plates are jointly fixedly connected to a long plate. The inner wall of the long plate is fixedly connected to a wire. The front side of the second detection device is fixedly connected to a socket.

[0007] Preferably, each of the support plates has a first rotating shaft rotatably connected to its inner wall, and a flip plate is fixedly connected to the outer surface of each first rotating shaft.

[0008] Preferably, a second rotating shaft is rotatably connected to the inner wall of each of the flipping plates, and a positioning roller is fixedly connected to the outer surface of each of the second rotating shafts.

[0009] Preferably, a fixing plate is fixedly connected to both sides of the second detection device, and a first reset spring is fixedly connected to the bottom surface of each fixing plate and the top end of the spiral shaft.

[0010] Preferably, each of the first reset springs is fixedly connected to a positioning shaft at its top end, and the outer surface of each positioning shaft is slidably connected to the interior of the fixed plate.

[0011] Preferably, each of the spiral shafts is fixedly connected to a bullseye bearing at its bottom end, and the outer surface of each of the transmission gear plates is slidably connected to the interior of the second detection device.

[0012] Preferably, a handle and a fixed frame are fixedly connected to the upper surface of the second detection device, a display screen is snapped into the inside of the fixed frame, one end of the wire is fixedly connected to the front of the display screen, and several identical control buttons are fixedly connected to the front of the second detection device.

[0013] Preferably, the automatic latching mechanism includes a fixing block, the back of which is fixedly connected to one side of the second detection device, and a latching plate is fixedly connected to the bottom surface of the fixing block. A first rectangular block and a second rectangular block are fixedly connected to the front of the first detection device. A second return spring is fixedly connected to the inner sidewall of the first rectangular block. A sliding shaft is fixedly connected to one end of the second return spring. The outer surface of the sliding shaft is slidably connected to the interior of the first rectangular block and the second rectangular block. A drive shaft is fixedly connected to one end of the sliding shaft. The drive shaft is slidably connected to the interior of the first rectangular block and is disposed in the inner cavity of the second return spring.

[0014] Preferably, the inner wall of the card plate is rotatably connected to a long shaft, and the outer surface of the long shaft is fixedly connected to a circular shaft.

[0015] An online monitoring device for hydraulic gate hoists and its usage method, specifically including the following steps:

[0016] S1: First, using the handle fixed to the upper surface of the second testing device, flip the second testing device, which is hinged to the first testing device, upwards to open it, separating the first and second testing devices. At this point, accurately place the steel wire rope of the hydraulic gate hoist to be tested into the pre-drilled semi-circular groove on the surface of the first testing device. This semi-circular groove matches the outer diameter of the steel wire rope, ensuring the rope remains stably centered in the testing area and preventing deviations that could affect testing accuracy during subsequent testing. After placing the steel wire rope, flip the second testing device towards the first testing device to close it. During this process, the support plate fixed to the outer surface of the second testing device will simultaneously drive the spiral shaft and the bullseye bearing installed at the bottom of the spiral shaft to rotate. Due to the support and obstruction of the steel wire rope between the first and second testing devices, the bullseye bearing... After contacting the surface of the wire rope, the helical shaft is pushed upward along the axial direction by the reaction force of the wire rope. The spiral stripes machined on the surface of the helical shaft and the spiral grooves opened on the inner wall of the helical cylinder form a precise fit. The linear upward motion of the helical shaft is converted into the rotational motion of the helical cylinder, which in turn drives the transmission gear fixed on the outer surface of the helical cylinder to rotate synchronously. The transmission gear maintains a meshing state with the transmission gear plates on both sides. The rotation of the transmission gear drives the transmission gear plates to move horizontally towards the insertion hole on the front of the second detection device. The long plate fixed on the front of the two sets of transmission gear plates moves synchronously with the transmission gear plates, and the wire fixed on the inner wall of the long plate is also pushed to the insertion hole. Finally, the wire is accurately inserted into the insertion hole. The whole process does not require the staff to manually insert or remove the wire, effectively reducing manual operation steps and improving the efficiency of the detection preparation stage.

[0017] S2: After the wire rope to be tested is placed in the semi-circular groove of the first testing device, the second testing device needs to be flipped and closed towards the first testing device. During this process, the fixing block fixedly connected to one side of the second testing device will move down synchronously with the second testing device, and the clamping plate fixed to the bottom surface of the fixing block will also move closer to the first testing device. When the clamping plate moves down to contact the sliding shaft on the front of the first testing device, the clamping plate generates a squeezing force on the sliding shaft along the inclined direction by means of the inclined structure of the sliding shaft surface. This squeezing force is decomposed into a horizontal component force that pushes the sliding shaft to move into the interior of the first rectangular block, causing the sliding shaft to overcome the elastic force of the second return spring and gradually contract into the inner cavity of the first rectangular block. At this time, the second return spring is in a compressed energy storage state, and with the second testing device... As the cover closes, the clamping plate continues to move downwards until it fully contacts one side of the first detection device. At this point, the pre-drilled circular hole on the surface of the clamping plate is aligned with the axis of the sliding shaft and the inner axis of the second rectangular block. After the clamping plate loses its squeezing effect, the second return spring releases its stored elastic potential energy, generating a reverse thrust that pushes the sliding shaft to move along the axial direction. This allows the sliding shaft to pass through the circular hole in the clamping plate and the inner cavity of the second rectangular block in sequence, ultimately achieving the limiting and fixing of the sliding shaft to the clamping plate. Through this series of mechanical linkages, the first and second detection devices are securely clamped together as one unit. Automatic clamping can be completed without manual operation of the buckles and other components, ensuring the overall structural stability of the device during subsequent testing and preventing the wire rope detection accuracy from being affected by loosening of the device.

[0018] 1. This invention features a spiral shaft. When the steel wire rope to be tested is placed between the first and second testing devices, and the second testing device is placed on top of the first testing device, the second testing device will cause the spiral shaft and bullseye bearing to rotate. However, due to the presence of the steel wire rope between the first and second testing devices, the bullseye bearing will drive the spiral shaft to move upward under the action of the steel wire rope. The spiral stripes on the surface of the spiral shaft will enter the spiral grooves opened on the inner wall of the spiral cylinder, causing the spiral cylinder to rotate. This, in turn, drives the transmission gear to rotate. Utilizing the meshing relationship between the transmission gear and the transmission gear plate, the transmission gear plate, the long plate, and the wire can be moved towards the insertion hole, allowing the wire to be inserted into the insertion hole, thus achieving automatic wiring without the need for manual operation.

[0019] 2. By providing a locking plate, when the second detection device is placed on top of the first detection device, the locking plate can utilize the inclined surface design of the sliding shaft surface to push the sliding shaft to move to the position of the second return spring, causing the sliding shaft to retract into the interior of the first rectangular block. At this time, the locking plate will contact one side of the first detection device, and the surface of the locking plate is provided with a circular hole for the sliding shaft to move. Therefore, under the action of the second return spring, the sliding shaft can extend into the interior of the locking plate and the second rectangular block to complete the locking operation and achieve the purpose of automatic locking.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figure 1-6 An online monitoring device for a hydraulic gate hoist and its usage method, comprising a first detection device 1, an automatic connection mechanism 2 disposed above the first detection device 1, and an automatic locking mechanism 3 disposed on the outside of the first detection device 1.

[0030] The automatic connection mechanism 2 includes a second detection device 208 and two sets of support plates 201. The bottom surface of the second detection device 208 is movably hinged to the upper surface of the first detection device 1. There are two support plates 201 in each set. The outer surfaces of the two sets of support plates 201 are respectively fixedly connected to the outer surfaces of the first detection device 1 and the second detection device 208. The inner walls of the two support plates 201 are rotatably connected to two spiral cylinders 218. Each spiral cylinder 218 has a spiral shaft 215 slidably connected inside. The outer surface of each spiral cylinder 218 is fixedly connected to a transmission gear 217. The outer surface of each transmission gear 217 is meshed with a transmission tooth plate 202. The front sides of the two transmission tooth plates 202 are fixedly connected to a long plate 203. The inner wall of the long plate 203 is fixedly connected to a wire 205. The front side of the second detection device 208 is fixedly connected to a socket 204.

[0031] Each support plate 201 has a first rotating shaft 216 rotatably connected to its inner wall, and a flip plate 213 is fixedly connected to the outer surface of each first rotating shaft 216. By setting the first rotating shaft 216 and the flip plate 213, the angle of the flip plate 213 can be adjusted by using the first rotating shaft 216, which is convenient for clamping the wire rope.

[0032] Each flip plate 213 has a second rotating shaft 212 rotatably connected to its inner wall, and a positioning roller 211 is fixedly connected to the outer surface of each second rotating shaft 212. By setting the positioning roller 211, the steel wire rope can be limited.

[0033] The second detection device 208 has fixed plates 221 fixedly connected to both sides. Each fixed plate 221 has a first reset spring 219 fixedly connected to the bottom surface of the screw shaft 215 and the top surface of the screw shaft 215. By setting the fixed plates 221 and the first reset springs 219, the screw shaft 215 can be reset by the first reset springs 219.

[0034] Each first return spring 219 is fixedly connected to a positioning shaft 220 at its top end. The outer surface of each positioning shaft 220 is slidably connected to the inside of the fixing plate 221. By providing the positioning shaft 220, the positioning shaft 220 can be used to prevent the spiral shaft 215 from rotating, so that the spiral shaft 215 can only move up and down.

[0035] Each spiral shaft 215 is fixedly connected to the bottom end of a bullseye bearing 214, and the outer surface of each transmission gear plate 202 is slidably connected to the inside of the second detection device 208. By providing bullseye bearings 214, the friction between the spiral shaft 215 and the wire rope can be reduced.

[0036] The upper surface of the second detection device 208 is fixedly connected to a handle 207 and a fixing frame 209. The display screen 206 is snapped into the inside of the fixing frame 209. One end of the wire 205 is fixedly connected to the front of the display screen 206. Several identical control buttons 210 are fixedly connected to the front of the second detection device 208. The handle 207 provides gripping force to the second detection device 208, and the fixing frame 209 fixes the display screen 206.

[0037] The specific implementation method of this embodiment is as follows: First, the second detection device 208, which is hinged to the first detection device 1, is flipped upwards and opened using the handle 207 fixed on the upper surface of the second detection device 208, so that the first detection device 1 and the second detection device 208 are separated. At this time, the steel wire rope of the hydraulic gate hoist to be tested is accurately placed into the semi-circular groove pre-cut on the surface of the first detection device 1. The semi-circular groove is adapted to the outer diameter of the steel wire rope, which can ensure that the steel wire rope is stably in the center of the detection area and avoid the deviation affecting the detection accuracy during subsequent detection. After the steel wire rope is placed, the second detection device 208 is flipped over to cover the first detection device 1. During this process, the support plate 201 fixed on the outer surface of the second detection device 208 will simultaneously drive the spiral shaft 215 and the bullseye bearing 214 installed at the bottom of the spiral shaft 215 to rotate. Since there is a support barrier of steel wire rope between the first detection device 1 and the second detection device 208, the bullseye bearing 214 rotates with respect to the surface of the steel wire rope. Upon contact, the reaction force of the steel wire rope pushes the spiral shaft 215 upward along the axial direction. The spiral stripes machined on the surface of the spiral shaft 215 and the spiral grooves opened on the inner wall of the spiral cylinder 218 form a precise fit. The linear upward motion of the spiral shaft 215 is converted into the rotational motion of the spiral cylinder 218, which in turn drives the transmission gear 217 fixed on the outer surface of the spiral cylinder 218 to rotate synchronously. The transmission gear 217 maintains a meshing state with the transmission gear plates 202 on both sides. The rotation of the transmission gear 217 drives the transmission gear plates 202 to move horizontally towards the insertion hole 204 on the front of the second detection device 208. The long plate 203 fixed on the front of the two sets of transmission gear plates 202 moves synchronously with the transmission gear plates 202, and the wire 205 fixed on the inner wall of the long plate 203 is also pushed to the insertion hole 204. Finally, the wire 205 is accurately inserted into the insertion hole 204. The whole process does not require the staff to manually insert or remove the wire 205, effectively reducing manual operation steps and improving the efficiency of the detection preparation stage.

[0038] Example 2

[0039] Please see Figure 1-6The automatic latching mechanism 3 includes a fixing block 301. The back of the fixing block 301 is fixedly connected to one side of the second detection device 208. A latching plate 306 is fixedly connected to the bottom surface of the fixing block 301. A first rectangular block 302 and a second rectangular block 307 are fixedly connected to the front of the first detection device 1. A second return spring 304 is fixedly connected to the inner wall of the first rectangular block 302. A sliding shaft 305 is fixedly connected to one end of the second return spring 304. The outer surface of the sliding shaft 305 is slidably connected to the interior of the first rectangular block 302 and the second rectangular block 307. A transmission shaft 303 is fixedly connected to one end of the sliding shaft 305. The transmission shaft 303 is slidably connected to the interior of the first rectangular block 302. The transmission shaft 303 is located in the inner cavity of the second return spring 304.

[0040] The inner wall of the card plate 306 is rotatably connected to a long shaft 308, and the outer surface of the long shaft 308 is fixedly connected to a circular shaft 309. By setting the long shaft 308 and the circular shaft 309, the long shaft 308 can drive the circular shaft 309 to rotate, and the rotation of the circular shaft 309 can reduce the friction between the card plate 306 and the sliding shaft 305.

[0041] The specific implementation of this embodiment is as follows: After the wire rope to be tested is placed in the semi-circular groove of the first testing device 1, the second testing device 208 needs to be flipped and closed towards the first testing device 1. During this process, the fixing block 301 fixedly connected to one side of the second testing device 208 will move down synchronously with the second testing device 208, and the clamping plate 306 fixed to the bottom surface of the fixing block 301 will also move closer to the first testing device 1. When the clamping plate 306 moves down to contact the sliding shaft 305 on the front of the first testing device 1, the clamping plate 306 generates a squeezing force on the sliding shaft 305 along the inclined direction by means of the inclined structure on the surface of the sliding shaft 305. This squeezing force is decomposed into a horizontal component force that pushes the sliding shaft 305 to move into the interior of the first rectangular block 302, causing the sliding shaft 305 to overcome the elastic force of the second return spring 304 and gradually contract into the inner cavity of the first rectangular block 302. At this time, the second return spring 304 is in a state of compressed energy storage. As the second detection device 208 continues to close, the clamping plate 306 continues to move downward until it is in complete contact with one side of the first detection device 1. At this time, the pre-drilled circular hole on the surface of the clamping plate 306 is exactly aligned with the axis of the sliding shaft 305 and the inner axis of the second rectangular block 307. After the clamping action of the clamping plate 306 is removed, the second return spring 304 releases the stored elastic potential energy, generating a reverse thrust to push the sliding shaft 305 to move along the axial direction, so that the sliding shaft 305 passes through the circular hole of the clamping plate 306 and the inner cavity of the second rectangular block 307 in sequence, finally realizing the limiting and fixing of the sliding shaft 305 on the clamping plate 306. Through this series of mechanical linkages, the first detection device 1 and the second detection device 208 are firmly clamped together as one unit. Automatic clamping can be completed without the need for manual operation of the buckles and other components, ensuring the overall structural stability of the device during subsequent testing and avoiding the impact of device loosening on the wire rope detection accuracy.

[0042] Example 3

[0043] Please see Figure 1-6 The specific implementation method of this embodiment is as follows:

[0044] An online monitoring device for hydraulic gate hoists and its usage method, specifically including the following steps:

[0045] S1: First, the second detection device 208, which is hinged to the first detection device 1, needs to be flipped upwards and opened using the handle 207 fixed on the upper surface of the second detection device 208, so that the first detection device 1 and the second detection device 208 are separated. At this time, the steel wire rope of the hydraulic gate hoist to be tested is accurately placed into the semi-circular groove pre-cut on the surface of the first detection device 1. The semi-circular groove is adapted to the outer diameter of the steel wire rope, which can ensure that the steel wire rope is stably in the center of the detection area, avoiding deviation during subsequent detection and affecting the detection accuracy. After the steel wire rope is placed, the second detection device 208 is flipped over to close the first detection device 1. During this process, the support plate 201 fixed on the outer surface of the second detection device 208 will simultaneously drive the spiral shaft 215 and the bullseye bearing 214 installed at the bottom of the spiral shaft 215 to rotate. Since there is a support barrier of steel wire rope between the first detection device 1 and the second detection device 208, after the bullseye bearing 214 contacts the surface of the steel wire rope... The reaction force of the steel wire rope will push the spiral shaft 215 to move upward along the axis. The spiral stripes processed on the surface of the spiral shaft 215 and the spiral grooves opened on the inner wall of the spiral cylinder 218 form a precise fit. The linear upward motion of the spiral shaft 215 is converted into the rotational motion of the spiral cylinder 218, which in turn drives the transmission gear 217 fixed on the outer surface of the spiral cylinder 218 to rotate synchronously. The transmission gear 217 maintains a meshing state with the transmission gear plates 202 on both sides. The rotation of the transmission gear 217 will drive the transmission gear plates 202 to move horizontally towards the insertion hole 204 on the front of the second detection device 208. The long plate 203 fixed on the front of the two sets of transmission gear plates 202 moves synchronously with the transmission gear plates 202. The wire 205 fixed on the inner wall of the long plate 203 is also pushed to the insertion hole 204. Finally, the wire 205 is accurately inserted into the insertion hole 204. The whole process does not require the staff to manually insert or remove the wire 205, effectively reducing manual operation steps and improving the efficiency of the detection preparation stage.

[0046] S2: After the wire rope to be tested is placed in the semi-circular groove of the first testing device 1, the second testing device 208 needs to be flipped and closed towards the first testing device 1. During this process, the fixing block 301 fixedly connected to one side of the second testing device 208 will move down synchronously with the second testing device 208, and the clamping plate 306 fixed to the bottom surface of the fixing block 301 will also move closer to the first testing device 1. When the clamping plate 306 moves down to contact the sliding shaft 305 on the front of the first testing device 1, with the help of the inclined structure on the surface of the sliding shaft 305, the clamping plate 306 generates a squeezing force on the sliding shaft 305 along the inclined direction. This squeezing force is decomposed into a horizontal component force that pushes the sliding shaft 305 into the interior of the first rectangular block 302, causing the sliding shaft 305 to overcome the elastic force of the second return spring 304 and gradually contract into the inner cavity of the first rectangular block 302. At this time, the second return spring 304 is in a compressed energy storage state. The second detection device 208 continues to close, and the clamping plate 306 continues to move down until it is in complete contact with one side of the first detection device 1. At this time, the pre-drilled circular hole on the surface of the clamping plate 306 is exactly aligned with the axis of the sliding shaft 305 and the inner axis of the second rectangular block 307. After the clamping action of the clamping plate 306 is removed, the second return spring 304 releases the stored elastic potential energy, generating a reverse thrust to push the sliding shaft 305 to move along the axial direction, so that the sliding shaft 305 passes through the circular hole of the clamping plate 306 and the inner cavity of the second rectangular block 307 in sequence, and finally realizes the limiting and fixing of the sliding shaft 305 on the clamping plate 306. Through this series of mechanical linkages, the first detection device 1 and the second detection device 208 are firmly clamped together as one unit. Automatic clamping can be completed without the need for manual operation of the buckles and other components by the staff, ensuring the overall structural stability of the device during subsequent detection and avoiding the impact of device loosening on the detection accuracy of the wire rope.

10. The use of the online monitoring device of the water conservancy hoist according to any one of claims 1-9, characterized in that: Specifically includes the following steps: S1: First, the second detection device (208) is opened by turning the handle (207) fixed on the upper surface of the second detection device (208) and the first detection device (1) is separated from the second detection device (208). At this time, the water conservancy hoist steel wire to be detected is accurately placed in the semicircular groove on the surface of the first detection device (1). The semicircular groove is matched with the outer diameter of the steel wire to ensure that the steel wire is stably positioned in the center of the detection area, avoiding deviation during the subsequent detection process and affecting the detection accuracy. After the steel wire is placed, the second detection device (208) is turned to the first detection device (1) direction. In this process, the support plate (201) fixed on the outer surface of the second detection device (208) will synchronously drive the spiral shaft (215) and the bull's eye bearing (214) installed at the bottom of the spiral shaft (215) to turn. Because there is a support barrier between the first detection device (1) and the second detection device (208), the bull's eye bearing (214) will be pushed by the reaction force of the steel wire after contacting the surface of the steel wire, and the spiral shaft (215) will move upward along the axial direction. The spiral stripes on the surface of the spiral shaft (215) and the spiral grooves on the inner wall of the spiral cylinder (218) form a precise fit, and the linear upward movement of the spiral shaft (215) is converted into the rotary movement of the spiral cylinder (218), which in turn drives the transmission gear (217) fixed on the outer surface of the spiral cylinder (218) to rotate synchronously. The transmission gear (217) and the transmission tooth plate (202) on both sides are in meshing state, and the rotation of the transmission gear (217) will drive the transmission tooth plate (202) to move along the horizontal direction to the direction of the jack (204) in front of the second detection device (208). The long plate (203) fixed on the front of the two groups of transmission tooth plates (202) moves synchronously with the transmission tooth plate (202), and the wire (205) fixed in the inner wall of the long plate (203) is also pushed to the jack (204) at the same time. Finally, the wire (205) is accurately inserted into the jack (204), and the whole process does not need to manually plug the wire (205), effectively reducing the manual operation steps and improving the efficiency of the detection preparation stage. S2: When the steel wire rope to be detected is placed in the first detection device (1) semicircular groove, the second detection device (208) needs to be flipped and closed towards the first detection device (1). During this process, the fixed block (301) fixedly connected to one side of the second detection device (208) will move downward synchronously with the second detection device (208), and the clamping plate (306) fixed to the bottom surface of the fixed block (301) will also move towards the first detection device (1). When the clamping plate (306) moves downward to contact the sliding shaft (305) on the front surface of the first detection device (1), the clamping plate (306) generates a pressing force along the slope direction on the sliding shaft (305) by means of the slope structure on the surface of the sliding shaft (305). This pressing force is decomposed into a horizontal component that pushes the sliding shaft (305) to move towards the inside of the first rectangular block (302), which helps the sliding shaft (305) to overcome the elastic force of the second return spring (304) and gradually shrink into the inner cavity of the first rectangular block (302). At this time, the second return spring (304) is in a compressed energy storage state. As the second detection device (208) continues to close, the clamping plate (306) continues to move downward until it fully contacts one side of the first detection device (1). At this time, the circular hole on the surface of the clamping plate (306) is exactly in line with the axis of the sliding shaft (305) and the inner cavity axis of the second rectangular block (307). After losing the pressing effect of the clamping plate (306), the second return spring (304) releases the stored elastic potential energy and generates a reverse thrust to push the sliding shaft (305) to move along the axis direction. The sliding shaft (305) passes through the circular hole of the clamping plate (306) and the inner cavity of the second rectangular block (307) in turn, and finally realizes the limiting fixation of the clamping plate (306) by the sliding shaft (305). Through this series of mechanical linkage, the first detection device (1) and the second detection device (208) are firmly clamped together, without the need for manual operation of the clasp and other components, and the automatic clamping can be completed, ensuring the stability of the overall structure of the device during the subsequent detection process and avoiding the influence of the detection accuracy of the steel wire rope due to the loosening of the device.
