Description

Technical Field

[0001] The present invention relates to the technical field of vibration detection and analysis, and particularly to a steel rope vibration detection simulator for a cable crane. Background Art

[0002] With the continuous progress of bridge engineering technology, super-long-span steel box truss arch bridges have been widely used in crossing large rivers, valleys and other complex terrains due to their unique structural advantages and load-bearing capacity. However, the construction of such bridges is extremely difficult and poses higher requirements for construction equipment and technology. As an important equipment in bridge construction, the performance and stability of a cable crane are directly related to the safety and efficiency of construction. During the operation of the cable crane, the vibration of the steel rope is an issue that cannot be ignored. The vibration of the steel rope not only affects the stability and accuracy of the crane, but may also cause safety accidents. Therefore, it is particularly important to monitor the vibration of the steel rope of the cable crane in real time and evaluate it accurately.

[0003] In the patent with the publication number: CN110375944B and the patent name: A Horizontal Steel Wire Rope Bending Ejection Impact Vibration Detection Analysis Method and Device, the problems existing in the existing steel wire rope impact tension vibration devices or methods are mainly as follows: (1) The detection methods for the dynamic performance of the steel wire rope focus on the monitoring of the static single-point lateral vibration of the rope body, that is, static analysis. However, in the actual impact process, the impact vibration is dynamically transmitted along the rope string in the form of a rope string wave. Therefore, the wave transmission data inside the entire rope cannot be obtained; (2) The application working conditions described are mostly normal steady-state operation processes. It realizes the pre-tightening of the steel wire rope at different bending angles through a lead screw, and the use of two pairs of tapered roller bearings ensures the support strength in all directions; the cooperation of the trigger rope and the pin makes the trigger instantaneous and does not affect the ejection vibration after the steel wire rope is released. The use of the trigger rope and the protection rope ensures operation safety. However, it is found in actual use that when the lead screw drives a pin to press down the steel wire rope and the pin is pulled out instantly when using the trigger rope, causing the steel wire rope to quickly rebound, at the moment when the pin is pulled out, a huge inertial impact force will immediately be transmitted to the lead screw. After long-term use, the lead screw will bend and cannot drive the pin to move up and down as a whole. At the same time, due to its shape, the rod-shaped pin will cause the steel wire rope to move back and forth on the pin during the long-term friction process with the steel wire rope. Moreover, the rebound direction of the steel wire rope when the pin is pulled out largely depends on the position point where the pin is pressed down. Once the pressing position point is inclined, it is very easy for the steel wire rope to rebound not vertically but at multiple angles during the rebound process, and it will circle in the air during the rebound process. The overall test will have errors, and when rebounding at multiple angles, it is extremely easy for the rebounding steel wire rope to hit the overall lead screw conveying structure, which will not only cause damage to the device but also greatly reduce the success rate and accuracy of the test. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel rope vibration detection simulator for a cable crane to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A steel rope vibration detection simulator for a cable crane, including two vertical walls. A second articulated traction member is fixedly connected to the outside of one of the vertical walls, and a rotating lead screw is movably connected to the outside of the other vertical wall. A first worm gear is installed on the outside of the rotating lead screw, and a first worm is meshed and connected to the outside of the first worm gear. The first worm is driven by an external driver. One end of the rotating lead screw close to the vertical wall is articulated with a first articulated traction member. Fixed ends of the first articulated traction member and the second articulated traction member are both clamped with a steel rope of the cable crane, and a pressing structure is clamped on the outside of the steel rope of the cable crane.

[0006] Among them, the pressing structure includes a first electromagnet block and a second electromagnet block. The first electromagnet block and the second electromagnet block adsorb each other and are sleeved on the outside of the steel rope of the cable crane. One side of the first electromagnet block and the second electromagnet block close to the steel rope of the cable crane are integrally formed with inclined parts. The inclined parts of the second electromagnet block and the first electromagnet block are mutually attached to form an inverted "V" shape. A plurality of traction ropes are connected to the bottoms of the first electromagnet block and the second electromagnet block. One end of the traction rope far from the first electromagnet block and the second electromagnet block is connected to a winding and tensioning structure. The winding and tensioning structure is located at the middle position between the two vertical walls. One side of the two adjacent vertical walls is movably connected with a square moving optical rod, and a high-speed camera is installed on the square moving optical rod.

[0007] Preferably, a plurality of placement grooves are formed on one side of the first electromagnet block close to the second electromagnet block. An elastic rubber block is integrally formed inside the placement groove. One side of the elastic rubber block far from the placement groove is integrally formed with a plug block. A plurality of plug slots are formed on one side of the second electromagnet block close to the first electromagnet block. The plug slots are adapted to the plug blocks.

[0008] Preferably, a plurality of third electromagnet blocks are integrally formed inside the second electromagnet block. The third electromagnet blocks are communicated with the inside of the plug slots. A plurality of the third electromagnet blocks are located at the middle position of the second electromagnet block. A plurality of the third electromagnet blocks are used to start before the first electromagnet block and the second electromagnet block are separated, so that a repulsive force is generated between the second electromagnet block and the first electromagnet block before they are separated. When the second electromagnet block cancels power supply and loses the adsorption to the first electromagnet block, the repulsive force already generated between the third electromagnet block and the first electromagnet block will quickly push the first electromagnet block and the second electromagnet block to separate.

[0009] Preferably, a plurality of elastic ropes are integrally formed inside the insertion slot. The elastic ropes are used to provide a blocking resilience when the insertion block is inserted into the insertion slot. When the magnetic attraction between the first electromagnet block and the second electromagnet block disappears, the plurality of elastic ropes located inside the insertion slot will push the insertion block inserted into the insertion slot outwards, reducing the situation where the insertion block and the insertion slot are still stuck when the first electromagnet block and the second electromagnet block need to be separated.

[0010] Preferably, one side of the insertion slot and the insertion block adjacent to each other are both conical surfaces.

[0011] Preferably, the winding and tensioning structure includes a lower mounting plate. The lower mounting plate is located between the two vertical walls. Four vertical plates are fixedly connected to the lower mounting plate. A rotating roller is rotatably connected between every two vertical plates. The traction rope is wound around the outside of the rotating roller. One end of the rotating roller penetrates outside the vertical plate and is fixedly connected to a second worm gear. A second worm is rotatably connected to the lower mounting plate. A driving motor is fixedly connected to the lower mounting plate. The output shaft of the driving motor is fixedly connected to one end of the second worm. The second worm gear is meshed with the second worm.

[0012] Preferably, a transverse vertical rod is fixedly connected to one side of the two adjacent vertical walls. Two water storage tanks are placed on both sides of the vertical wall. The water storage tanks are parallel to the positions of the first electromagnet block and the second electromagnet block. When the first electromagnet block and the second electromagnet block separate and swing to both sides, the transverse vertical rod and the water storage tank will, with the transverse vertical rod as the winding center point, cooperate with the traction rope to swing the first electromagnet block and the second electromagnet block into the water storage tank, and the water pool inside the water storage tank buffers the downward swinging impact force generated by the first electromagnet block and the second electromagnet block.

[0013] Preferably, buckles are installed on the outsides of the first electromagnet block and the second electromagnet block. A first pull rope is connected to the buckle on the outside of the first electromagnet block, and a second pull rope is connected to the outside of the second electromagnet block.

[0014] Preferably, sliding grooves are opened on the outer walls of the two vertical walls. The square moving optical rod is slidably connected inside the sliding grooves. The bottom of the high-speed camera is connected with a sliding seat by screws, and the sliding seat is slidably connected to the square moving optical rod.

[0015] Preferably, both ends of the square moving optical rod and the inner wall of the sliding seat are set to be rough and hairy surfaces.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the present invention, in this application, the steel cable of the cable crane is pressed down by the combined adsorption between the first electromagnet block and the second electromagnet block, and the steel cable of the cable crane is limited by the inverted "V" shaped structure formed by the inclined parts, so as to avoid the phenomenon of left - right shaking of the steel cable of the cable crane. At the same time, the first electromagnet block and the second electromagnet block provide a pulling force downward, and can separate to both sides when separated. The whole will not cause excessive collision between the rebounding high - speed camera and other components, avoiding the impact of the collision on the rebound of the steel cable of the cable crane, and further improving the stability and accuracy of the steel cable of the cable crane during the detection process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: As Figure 1 shown, a cable crane steel rope vibration detection simulator of the present application includes two vertical walls 100. A second articulated traction member 107 is fixedly connected to the outside of one of the vertical walls 100, and a rotating lead screw 104 is movably connected to the outside of the other vertical wall 100. A first worm gear 105 is installed on the outside of the rotating lead screw 104. A first worm 106 is meshed and connected to the outside of the first worm gear 105. The first worm 106 is driven by an external driver. One end of the rotating lead screw 104 close to the vertical wall 100 is articulated with a first articulated traction member 101. The fixed ends of the first articulated traction member 101 and the second articulated traction member 107 are both clamped with a cable crane steel rope 102. A pressing structure is clamped on the outside of the cable crane steel rope 102.

[0027] Among them, the pressing structure includes a first electromagnet block 108 and a second electromagnet block 113. The first electromagnet block 108 and the second electromagnet block 113 adsorb each other and are sleeved on the outside of the cable crane steel rope 102. On the side of the first electromagnet block 108 and the second electromagnet block 113 close to the cable crane steel rope 102, inclined portions 103 are integrally formed. The inclined portions 103 of the second electromagnet block 113 and the first electromagnet block 108 are mutually attached to form an inverted "V" shape. A plurality of traction ropes 110 are connected to the bottoms of the first electromagnet block 108 and the second electromagnet block 113. One end of the traction rope 110 away from the first electromagnet block 108 and the second electromagnet block 113 is connected to a winding and tensioning structure 109. The winding and tensioning structure 109 is located at the middle position between the two vertical walls 100. A square moving optical rod 111 is movably connected to the adjacent sides of the two vertical walls 100. A high-speed camera 112 is installed on the square moving optical rod 111.

[0028] Specifically, during the use process, the staff member clamps the steel cable 102 of the cable crane to the connection end of the first articulated traction member 101 and the second articulated traction member 107. After the steel cable 102 of the cable crane is fixed, the staff member drives the first worm 106 to rotate by starting an external driver. During the rotation of the first worm 106, the first worm gear 105 can be driven to rotate. During the rotation of the first worm gear 105, the rotating lead screw 104 can be driven to rotate. During the rotation of the rotating lead screw 104, it can move inside the vertical wall 100. When the rotating lead screw 104 moves away from the first articulated traction member 101, it will stretch the first articulated traction member 101. When the first articulated traction member 101 moves by stretching, it will drive the steel cable 102 of the cable crane to be tightened. After the steel cable 102 of the cable crane is tightened, the staff member places the first electromagnet block 108 and the second electromagnet block 113 outside the steel cable 102 of the cable crane, and makes the inverted "V" - shaped structure formed by the inclined part 103 fit with the steel cable 102 of the cable crane. After the fitting is completed, the second electromagnet block 113 is powered on, and then the first electromagnet block 108 is powered on. When the second electromagnet block 113 and the first electromagnet block 108 are powered on, the second electromagnet block 113 and the first electromagnet block 108 will generate magnetic force. When the second electromagnet block 113 generates magnetic force as a whole, it will adsorb the first electromagnet block 108. When the first electromagnet block 108 and the second electromagnet block 113 are completely adsorbed together, a lower pressing plate can be formed. After the lower pressing plate is formed, the winding and tightening structure 109 is started to drive the traction rope 110 to wind. When the traction rope 110 is wound, it will drive the first electromagnet block 108 and the second electromagnet block 113 to move downward. During the downward movement of the first electromagnet block 108 and the second electromagnet block 113, the steel cable 102 of the cable crane will be bent downward. When the steel cable 102 of the cable crane is in a straight state and is continuously pulled downward and bent, the stress state of the steel cable 102 of the cable crane can be simulated. When the overall downward pressure reaches the specified degree, the power - on state of the second electromagnet block 113 is cancelled. When the second electromagnet block 113 loses the power - on state, the second electromagnet block 113 will separate from the first electromagnet block 108. When the magnetic force adsorption between the second electromagnet block 113 and the first electromagnet block 108 is lost, the deformed steel cable 102 of the cable crane due to downward pressure will quickly rebound and separate the first electromagnet block 108 and the second electromagnet block 113. When the steel cable 102 of the cable crane loses the restriction of the second electromagnet block 113 and the first electromagnet block 108 and is pressed downward, the steel cable 102 of the cable crane will quickly produce reciprocating rebounds. During the reciprocating rebound process, a high - speed camera 112 is used to monitor the reciprocating rebound of the steel cable 102 of the cable crane.

[0029] Furthermore, during the process of pressing down the steel cable 102 of the cable crane, the inverted "V" structure generated by the overall inclined part 103 can ensure that the steel cable 102 of the cable crane always remains in the same position during the process of pressing down the steel cable 102 of the cable crane, without the situation of swaying back and forth. When the steel cable 102 of the cable crane does not sway back and forth during the process of pressing down and rebounding, more accurate positioning simulation detection can be achieved, reducing the phenomenon of directional change and inaccurate measurement of the steel cable 102 of the cable crane during the rebounding process due to frequent position changes.

[0030] As Figure 1 - Figure 2 shown, the winding and tensioning structure 109 includes a lower mounting plate 500, the lower mounting plate 500 is located between two vertical walls 100, four vertical plates 501 are fixedly connected to the lower mounting plate 500, a rotating roller 502 is rotatably connected between every two vertical plates 501, a traction rope 110 is wound around the outside of the rotating roller 502, one end of the rotating roller 502 penetrates outside the vertical plate 501 and is fixedly connected with a second worm gear 503, a second worm 504 is rotatably connected to the lower mounting plate 500, a driving motor 505 is fixedly connected to the lower mounting plate 500, an output shaft of the driving motor 505 is fixedly connected with one end of the second worm 504, and the second worm gear 503 is meshed with the second worm 504.

[0031] Specifically, during the use process, when it is necessary to press down the steel cable 102 of the cable crane, starting the driving motor 505 can drive the second worm 504 to rotate. During the rotation of the second worm 504, two second worm gears 503 can be driven to rotate. When the second worm gears 503 continue to rotate, the rotating roller 502 can be driven to rotate. During the continuous rotation of the rotating roller 502, the traction rope 110 can be continuously wound, thereby pulling the first electromagnet block 108 and the second electromagnet block 113 to move downward continuously, and pulling the steel cable 102 of the cable crane to generate deformation during the continuous downward movement.

[0032] As Figure 1 shown, sliding grooves are formed on the outer walls of the two vertical walls 100, a square moving optical rod 111 is slidably connected inside the sliding grooves, the bottom of the high-speed camera 112 is connected with a sliding seat 800 through screws, the sliding seat 800 is slidably connected to the square moving optical rod 111, and both ends of the square moving optical rod 111 and the inner wall of the sliding seat 800 are set as rough matte surfaces.

[0033] Specifically, the up-and-down position of the square moving optical rod 111 can be adjusted through the setting of the sliding groove, so as to adjust the up-and-down position of the high-speed camera 112. And the left-and-right position of the high-speed camera 112 can be adjusted through the setting of the sliding seat 800, which facilitates the staff to install the high-speed camera 112 at any position. The rough surface setting can prevent the sliding seat 800 from sliding randomly inside the square moving optical rod 111 and prevent the square moving optical rod 111 from sliding randomly inside the sliding groove.

[0034] The technical solution in the above embodiment of the present application has at least the following technical effects or advantages: Compared with the prior art, in the present application, the cable crane steel rope 102 is pressed down by the combined adsorption between the first electromagnet block 108 and the second electromagnet block 113, and the cable crane steel rope 102 is limited by the inverted "V" shaped structure formed by the inclined portion 103, so as to avoid the phenomenon of left-and-right shaking of the cable crane steel rope 102.

[0035] Embodiment 2: Considering that the first electromagnet block 108 and the second electromagnet block 113 will continuously press down the cable crane steel rope 102 under the pulling of the winding and tensioning structure 109. However, the first electromagnet block 108 and the second electromagnet block 113 are adsorbed by electromagnetic force, and the cable crane steel rope 102 will always be located between the first electromagnet block 108 and the second electromagnet block 113 due to the existence of the inclined portion 103. When the pulling force is too large, the adsorption between the first electromagnet block 108 and the second electromagnet block 113 is likely to be cut by the cable crane steel rope 102, resulting in the separation between the first electromagnet block 108 and the second electromagnet block 113. For the above technical problems, the present application proposes the following technical solution to solve the above technical problems, specifically:

[0036] As Figure 3 shown, a plurality of placement grooves 201 are provided on the side of the first electromagnet block 108 close to the second electromagnet block 113. An elastic rubber block 202 is integrally formed inside the placement groove 201. A plug block 203 is integrally formed on the side of the elastic rubber block 202 away from the placement groove 201. A plurality of plug slots 200 are provided on the side of the second electromagnet block 113 close to the first electromagnet block 108. The plug slots 200 are adapted to the plug blocks 203.

[0037] Specifically, during the use process, when the first electromagnet block 108 and the second electromagnet block 113 generate adsorption, the second electromagnet block 113 will adsorb the insertion block 203 located inside the placement groove 201 outward. And during the outward adsorption process, the insertion block 203 will pull the elastic rubber block 202 to deform. When the elastic rubber block 202 deforms, with the adsorption of the second electromagnet block 113, the insertion block 203 will gradually enter the inside of the insertion slot 200. The material of the insertion block 203 is iron. When the insertion block 203 gradually enters the inside of the insertion slot 200, a secondary clamping phenomenon will occur between the insertion block 203 and the insertion slot 200. When the secondary clamping is formed, the connection between the first electromagnet block 108 and the second electromagnet block 113 will be further strengthened. When the traction rope 110 pulls the first electromagnet block 108 and the second electromagnet block 113, the insertion block 203 located inside the insertion slot 200 can be tilted. When the insertion block 203 is tilted, an abutting phenomenon can be formed with the insertion slot 200, thus preventing the first electromagnet block 108 and the second electromagnet block 113 from separating.

[0038] Furthermore, when the second electromagnet block 113 no longer generates magnetic force to adsorb the first electromagnet block 108, the elastic rubber block 202 deformed due to the adsorption force will rebound, thereby pulling the insertion block 203 back out of the inside of the insertion slot 200 and pulling the insertion block 203 back to its original position.

[0039] The technical solutions in the embodiments of the present application described above have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, during the process of generating the adsorption force by the second electromagnet block 113, the insertion block 203 can be sucked into the inside of the insertion slot 200, so that a clamping phenomenon is formed through the insertion between the insertion block 203 and the insertion slot 200, further strengthening the stability between the first electromagnet block 108 and the second electromagnet block 113. When the second electromagnet block 113 is separated from the first electromagnet block 108, the elastic rubber block 202 can also pull the insertion block 203 back to its original position, and the overall separation between the first electromagnet block 108 and the second electromagnet block 113 will not be affected, strengthening the overall stability.

[0040] Embodiment 3: Considering that it takes a certain amount of time for the insertion block 203 to be pulled back to its original position by the elastic rubber block 202, but after the first electromagnet block 108 and the second electromagnet block 113 lose magnetic force and separate, the cable crane steel rope 102 with huge stress will instantly push apart the two first electromagnet blocks 108 and the second electromagnet block 113. When the insertion block 203 exists, during the rapid rebound process of the cable crane steel rope 102, the insertion block 203 may not fully return to its original position and may come into contact with the cable crane steel rope 102, resulting in the phenomenon that the cable crane steel rope 102 hits the insertion block 203. When the cable crane steel rope 102 is hit, it will affect the energy generated when the cable crane steel rope 102 presses down and rebounds, thereby affecting the rebound detection of the cable crane steel rope 102. To solve the above technical problems, the present application proposes the following technical solutions, specifically:

[0041] As Figure 4 shown, a plurality of third electromagnet blocks 300 are integrally formed inside the second electromagnet block 113. The third electromagnet blocks 300 communicate with the inside of the insertion slot 200. The plurality of third electromagnet blocks 300 are located at the middle position of the second electromagnet block 113. The plurality of third electromagnet blocks 300 are used to start before the first electromagnet block 108 and the second electromagnet block 113 separate, so that the second electromagnet block 113 generates a repulsive force before separating from the first electromagnet block 108. When the second electromagnet block 113 cancels power supply and loses the adsorption on the first electromagnet block 108, the repulsive force already generated between the third electromagnet block 300 and the first electromagnet block 108 will quickly push the first electromagnet block 108 and the second electromagnet block 113 to separate from each other.

[0042] Specifically, during the use process, when it is necessary to separate the first electromagnet block 108 from the second electromagnet block 113, a plurality of third electromagnet blocks 300 located inside the second electromagnet block 113 are pre-activated and the power supply to the third electromagnet blocks 300 is a relatively small power supply, so that only a relatively small repulsive force appears between the third electromagnet blocks 300 and the first electromagnet block 108. And during the adsorption process of the second electromagnet block 113 and the first electromagnet block 108, the power supply needs to be maintained, that is, the adsorption force should be much greater than the repulsive force generated by the third electromagnet blocks 300. When separation is required, the power supply to the second electromagnet block 113 and the first electromagnet block 108 is cancelled, and the power supply to the third electromagnet blocks 300 is instantaneously increased, so that sufficient repulsive force can be generated during the overall separation. During the separation process, the power supply to the first electromagnet block 108 and the second electromagnet block 113 is cancelled, and the power supply to the third electromagnet blocks 300 is instantaneously increased. The steps of overall cancelling the power supply to the first electromagnet block 108, the second electromagnet block 113 and increasing the power supply to the third electromagnet blocks 300 are integrated in the same control operation button. First, the power supply to the first electromagnet block 108 and the second electromagnet block 113 is cancelled, and then the power is instantaneously increased. The overall cancellation of the power supply and the instantaneous increase in power are completed within 0.1 second - 0.3 second. During the separation process of the first electromagnet block 108 and the second electromagnet block 113, the repulsive force generated by the third electromagnet blocks 300 cooperates with the upward lifting force of the cable crane steel rope 102 to quickly separate the second electromagnet block 113 and the first electromagnet block 108, and drive the quick separation between the plug-in block 203 and the plug-in slot 200, avoiding the situation that the plug-in block 203 does not fully retract and hit the cable crane steel rope 102 during the separation process of the second electromagnet block 113 and the first electromagnet block 108.

[0043] Further, when the first electromagnet block 108 and the second electromagnet block 113 are separated, they will respectively generate a certain amount of throwing force to both sides, reducing the phenomenon of collision with the cable crane steel rope 102. Overall, there will be no other devices outside that will collide with the cable crane steel rope 102, avoiding the inaccurate measurement phenomenon caused by the collision.

[0044] Such as Figure 6As shown in the figure, a transverse vertical rod 600 is fixedly connected to one adjacent side of two vertical walls 100. Two water storage tanks 601 are placed on both sides of the vertical wall 100. The water storage tanks 601 are parallel to the positions of the first electromagnet block 108 and the second electromagnet block 113. When the first electromagnet block 108 and the second electromagnet block 113 separate and swing to both sides, the transverse vertical rod 600 and the water storage tanks 601 will use the transverse vertical rod 600 as the center of winding and cooperate with the traction rope 110 to swing the first electromagnet block 108 and the second electromagnet block 113 into the water storage tanks 601, and the water pool inside the water storage tanks 601 buffers the downward swinging impact force generated by the first electromagnet block 108 and the second electromagnet block 113.

[0045] Specifically, during the use process, after the first electromagnet block 108 and the second electromagnet block 113 are separated, the cable crane steel rope 102 will separate the first electromagnet block 108 and the second electromagnet block 113 and swing to both sides. The setting of the transverse vertical rod 600 can swing the traction rope 110 into the water storage tank 601. The water storage tank 601 stores water flow, and the stored water flow buffers the swinging first electromagnet block 108 and the second electromagnet block 113, reducing the excessive deformation generated when the first electromagnet block 108 and the second electromagnet block 113 collide with other objects. The square moving optical rod 111 is arranged behind the transverse vertical rod 600 to prevent the splashing water flow from blocking the shooting of the high-speed camera 112. At the same time, the first electromagnet block 108 and the second electromagnet block 113 provide a pulling force for the lower part and can separate to both sides during separation. The overall structure will not cause excessive collision between the rebounding high-speed camera 112 and other components, avoiding the collision from affecting the rebound of the cable crane steel rope 102, and further improving the stability and accuracy of the cable crane steel rope 102 during the detection process.

[0046] The technical solution in the above embodiment of the present application has at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, through the setting of the third electromagnet block 300, a repulsive force can be pre-generated by the third electromagnet block 300 in the middle when the first electromagnet block 108 and the second electromagnet block 113 are separated, and the repulsive force of the third electromagnet block 300 on the first electromagnet block 108 is increased during the process that the second electromagnet block 113 completely loses the magnetic force to adsorb the first electromagnet block 108, so as to quickly separate the first electromagnet block 108 and the second electromagnet block 113. When quickly separating the second electromagnet block 113 and the first electromagnet block 108, it is possible to avoid the contact between the insertion block 203 and the cable crane steel rope 102, and avoid the impact force generated when the cable crane steel rope 102 contacts the insertion block 203 from affecting the rebound of the cable crane steel rope 102.

[0047] Embodiment 4. Considering that when the plug-in block 203 is inserted into the inside of the plug-in slot 200, and when the steel cable of the cable crane 102 rebounds, the plug-in block 203 will tilt inside the plug-in slot 200, thus forming a clamping connection through the tilt of the plug-in block 203 inside the plug-in slot 200. However, after the tilt clamping connection is formed, when it is necessary to separate the first electromagnet block 108 and the second electromagnet block 113, some of the tilt-clamped plug-in blocks 203 may have a too tight clamping phenomenon. And when the plug-in block 203 is completely inserted into the inside of the plug-in slot 200, a deeper tilt clamping connection will be formed. During separation, some of the plug-in blocks 203 cannot rebound to the original position in time, resulting in a local residual clamping of the first electromagnet block 108 and the second electromagnet block 113, affecting the rebound of the steel cable 102 of the cable crane. For the above technical solutions, the present application proposes the following technical solutions, specifically:

[0048] As Figure 5 shown, a plurality of elastic ropes 400 are integrally formed inside the plug-in slot 200. The elastic ropes 400 are used to provide a blocking resilience when the plug-in block 203 is inserted into the inside of the plug-in slot 200. When the magnetic attraction force between the first electromagnet block 108 and the second electromagnet block 113 disappears, the plurality of elastic ropes 400 located inside the plug-in slot 200 will push the plug-in block 203 inserted into the inside of the plug-in slot 200 outwards, reducing the situation where there is still a clamping connection between the plug-in block 203 and the plug-in slot 200 when the first electromagnet block 108 and the second electromagnet block 113 need to be separated.

[0049] Specifically, through the arrangement of the plurality of elastic ropes 400, the plug-in block 203 is blocked from completely approaching and being inserted into the inside of the plug-in slot 200. And during the formation of the clamping connection, the plug-in block 203 will squeeze the plurality of elastic ropes 400, causing the elastic ropes 400 to deform. In the case of the deformation of the elastic ropes 400, a backward resilience can be given to the plug-in block 203. However, during the adsorption process of the second electromagnet block 113 and the first electromagnet block 108, the resilience generated by the deformation of the elastic ropes 400 will not affect the plug-in block 203 popping out of the inside of the plug-in slot 200. Instead, when the overall separation is carried out, the second electromagnet block 113 no longer generates an adsorption force on the plug-in block 203. When the adsorption force is no longer generated, the deformed elastic ropes 400 will drive the plug-in block 203 to rebound to the original position, thereby accelerating the speed of the plug-in block 203 rebounding to the original position and reducing the phenomenon that some of the plug-in blocks 203 are stuck too tightly inside the plug-in block 203.

[0050] As Figure 5As shown, one side of the insertion slot 200 and the insertion block 203 adjacent to each other is a conical surface. By means of the conical insertion slot 200 and insertion block 203, when the insertion slot 200 is inserted into the interior of the insertion block 203, it will not be skewed and unable to be inserted. Moreover, the conical insertion block 203 can also cooperate with the elastic rope 400 to eject the insertion block 203 faster, avoiding the situation where the side wall of the insertion block 203 is tightly clamped inside the insertion slot 200.

[0051] As Figure 6 shown, buckles 700 are installed outside both the first electromagnet block 108 and the second electromagnet block 113. A first pulling rope 701 is connected to the buckle 700 located outside the first electromagnet block 108, and a second pulling rope 702 is connected to the outside of the second electromagnet block 113.

[0052] Specifically, the buckle 700 can be used for mechanical clamping when the second electromagnet block 113 and the first electromagnet block 108 do not perform electromagnetic adsorption, and the buckle 700 is pulled open by using the first pulling rope 701 and the second pulling rope 702. When the buckle 700 is pulled open, the connection between the second electromagnet block 113 and the first electromagnet block 108 will be separated.

[0053] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
