Description

Technical Field

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

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

[0003] The patent publication number is CN110375944B, and the name is: A method and device for detecting and analyzing the bending and ejection impact vibration of a horizontally placed wire rope. The problems existing in the existing wire rope impact tension vibration device or method are as follows: (1) The detection method for the dynamic performance of the wire rope focuses on the monitoring of the static single-point lateral vibration of the rope body, that is, static analysis. In the actual impact process, the impact vibration is dynamically transmitted along the rope string in the form of a rope chord wave, so it is impossible to obtain the wave transmission data in the entire rope; (2) The application conditions described are mostly normal steady-state operation processes, and the pre-tightening of the wire rope at different bending angles is achieved by using a spiral screw. The use of two pairs of tapered roller bearings ensures the support strength in all directions; the combination of the trigger rope and the pin shaft makes the trigger instantaneous and does not affect the ejection vibration after the wire rope is released. The use of the trigger rope and the protective rope ensures the safety of operation. However, in actual use, it is found that the screw rod drives a pin shaft to press down. The wire rope and the pin are pulled out at the moment of using the trigger rope to make the wire rope rebound quickly. When the pin is pulled out, the huge inertial impact force will be immediately transmitted to the spiral screw. After long-term use, the spiral screw will bend, and the whole screw cannot drive the pin to move up and down. At the same time, the stick-shaped pin will cause the wire rope to move back and forth on the pin due to its shape during the long-term friction with the wire rope. And the rebound direction of the wire rope when the pin is pulled out depends to a large extent on the position point of the pressure on the pin. Once the pressure point is tilted, it is very easy for the wire rope to rebound at multiple angles instead of up and down during the rebound process, and it will circle in the air during the rebound process. There will be errors in the overall test, and in the case of multi-angle rebound, it is very easy for the rebounded wire rope to hit the overall screw conveying structure, which will not only cause damage to the device but also greatly reduce the success rate and accuracy of the test.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: Figure 1 As shown, the present application is a cable crane wire rope vibration detection simulator, comprising two vertical walls 100, wherein the exterior of one vertical wall 100 is fixedly connected with a second hinged traction member 107, and the exterior of the other vertical wall 100 is movably connected with a rotating screw 104, a first worm gear 105 is installed on the exterior of the rotating screw 104, and the exterior of the first worm gear 105 is meshedly connected with a first worm 106, and the first worm 106 is driven by an external driver, and an end of the rotating screw 104 close to the vertical wall 100 is hinged with a first hinged traction member 101, and the fixed ends of the first hinged traction member 101 and the second hinged traction member 107 are both clamped with a cable crane wire rope 102, and the exterior of the cable crane wire rope 102 is clamped with a pressing structure; Among them, the clamping structure includes a first electromagnet block 108 and a second electromagnet block 113, the first electromagnet block 108 and the second electromagnet block 113 are attracted to each other and are sleeved on the outside of the cable crane rope 102, the first electromagnet block 108 and the second electromagnet block 113 are both integrally formed with an inclined portion 103 on the side close to the cable crane rope 102, the second electromagnet block 113 and the inclined portion 103 of the first electromagnet block 108 fit each other in an inverted "V" shape, and the bottom of the first electromagnet block 108 and the second electromagnet block 113 are connected to a plurality of traction ropes 110, and the end of the traction rope 110 away from the first electromagnet block 108 and the second electromagnet block 113 is connected to a tensioning structure 109 around a receiving roll, and the tensioning structure 109 around a receiving roll is located in the middle position of the two vertical walls 100, and a square movable light rod 111 is movably connected to one side adjacent to the two vertical walls 100, and a high-speed camera 112 is installed on the square movable light rod 111.

[0020] Specifically, during use, the staff clamps the cable crane rope 102 to the connection end of the first articulated traction member 101 and the second articulated traction member 107. After the cable crane rope 102 is fixed, the staff starts the external driver to drive the first worm 106 to rotate. During the rotation of the first worm 106, the first worm wheel 105 can be driven to rotate. During the rotation of the first worm wheel 105, the rotating screw rod 104 can be driven to rotate. During the rotation of the rotating screw rod 104, it can move inside the vertical wall 100. When the rotating screw rod 104 moves to the side away from the first articulated traction member 101, the first articulated traction member 101 will be stretched. When the first articulated traction member 101 is stretched and moved, the cable crane steel rope 102 will be driven to be tightened. When the cable crane steel rope 102 is tightened, the staff will place the first electromagnet block 108 and the second electromagnet block 113 outside the cable crane steel rope 102, and fit the inverted "V" shape structure formed by the inclined portion 103 with the cable crane steel rope 102. After the fitting is completed, the second electromagnet block 113 is energized, and then the first electromagnet block 108 is energized. When the second electromagnet block 113 and the first electromagnet block 108 are energized, 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 exert magnetic force on the first electromagnet block 108. The magnet block 108 is adsorbed, and when the first electromagnet block 108 and the second electromagnet block 113 are completely adsorbed together, a lower pressure plate can be formed. After the lower pressure plate is formed, the winding and receiving roll tensioning structure 109 is started to drive the traction rope 110 to be wound. When the traction rope 110 is wound, the first electromagnet block 108 and the second electromagnet block 113 will move downward. During the downward movement of the first electromagnet block 108 and the second electromagnet block 113, the cable crane steel rope 102 will bend downward. When the cable crane steel rope 102 is in a straight state and is continuously pulled downward and bent, the stress state of the cable crane steel rope 102 can be simulated. When the overall pressure is reduced to a specified degree, the cable crane steel rope 102 is taken out. The power-on state of the second electromagnet block 113 is eliminated. When the second electromagnet block 113 loses the power-on state, the second electromagnet block 113 will be separated from the first electromagnet block 108. When the magnetic attraction between the second electromagnet block 113 and the first electromagnet block 108 is lost, the cable crane rope 102 that is pressed down to produce deformation will rebound quickly to separate the first electromagnet block 108 and the second electromagnet block 113. When the cable crane rope 102 loses the restricted downward pressure of the second electromagnet block 113 and the first electromagnet block 108, the cable crane rope 102 will quickly reciprocate and rebound. During the reciprocating rebound process, the high-speed camera 112 is used to monitor the reciprocating rebound of the cable crane rope 102.

[0021] Furthermore, during the process of pressing down the cable crane rope 102, the inverted "V" shape structure generated by the overall inclined portion 103 can ensure that the cable crane rope 102 is always in the same position during the process of pressing down the cable crane rope 102, and will not swing back and forth. When the cable crane rope 102 does not swing back and forth during the pressing down and rebounding process, more accurate positioning simulation detection can be achieved, thereby reducing the direction change rebound and inaccurate measurement phenomenon caused by the cable crane rope 102 during the rebound process due to frequent position changes.

[0022] like Figure 1-Figure 2 As shown, the winding and receiving roll tensioning structure 109 includes a lower mounting plate 500, which is located between two vertical walls 100, and four vertical plates 501 are fixedly connected to the lower mounting plate 500, and a rotating roller 502 is rotatably connected between every two vertical plates 501, and the traction rope 110 is wound around the outside of the rotating roller 502, one end of the rotating roller 502 passes through the outside of the vertical plate 501 and is fixedly connected to a second worm gear 503, and a second worm 504 is rotatably connected to the lower mounting plate 500, and a driving motor 505 is fixedly connected to the lower mounting plate 500, and the output shaft of the driving motor 505 is fixedly connected to one end of the second worm 504, and the second worm gear 503 is meshingly connected to the second worm 504.

[0023] Specifically, during use, when it is necessary to press down the cable crane rope 102, the second worm 504 can be driven to rotate by starting the drive motor 505. During the rotation of the second worm 504, the two second worm wheels 503 can be driven to rotate. When the second worm wheel 503 is continuously rotating, the rotating roller 502 can be driven to rotate. During the continuous rotation, the rotating roller 502 can continuously reel in the traction rope 110, thereby pulling the first electromagnet block 108 and the second electromagnet block 113 to move downward continuously, and the cable crane rope 102 is deformed during the continuous downward movement.

[0024] like Figure 1 As shown, the outer walls of the two vertical walls 100 are provided with sliding grooves, and the square movable light rod 111 is slidably connected to the inside of the sliding grooves. The bottom of the high-speed camera 112 is connected to the sliding seat 800 by screws, and the sliding seat 800 is slidably connected to the square movable light rod 111. Both ends of the square movable light rod 111 and the inner wall of the sliding seat 800 are set to rough fur surfaces.

[0025] Specifically, the upper and lower positions of the square movable light rod 111 can be adjusted by setting the slide groove, thereby adjusting the upper and lower positions of the high-speed camera 112, and the left and right positions of the high-speed camera 112 can be adjusted by setting the sliding seat 800, so that the staff can set up the high-speed camera 112 at any position conveniently, and the setting of the rough surface can prevent the sliding seat 800 from sliding freely inside the square movable light rod 111, and prevent the square movable light rod 111 from sliding freely inside the slide groove.

[0026] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present application, the cable crane 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 rope 102 is limited by the inverted "V"-shaped structure composed of the inclined portion 103, thereby preventing the cable crane rope 102 from shaking left and right.

[0027] Embodiment 2: Considering that the first electromagnet block 108 and the second electromagnet block 113 will continue to press down the cable crane rope 102 under the pull of the tensioning structure 109 around the receiving coil, but the first electromagnet block 108 and the second electromagnet block 113 are adsorbed by electromagnetic force, and the cable crane 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 tension is too large, the adsorption between the first electromagnet block 108 and the second electromagnet block 113 is easily cut by the cable crane rope 102, resulting in separation between the first electromagnet block 108 and the second electromagnet block 113. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figure 3 As shown, a plurality of placement grooves 201 are provided on a 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-in block 203 is integrally formed on a side of the elastic rubber block 202 away from the placement groove 201, and a plurality of plug-in grooves 200 are provided on a side of the second electromagnet block 113 close to the first electromagnet block 108, and the plug-in grooves 200 are adapted to the plug-in block 203.

[0028] Specifically, during use, when the first electromagnet block 108 and the second electromagnet block 113 are adsorbed, the second electromagnet block 113 will adsorb the plug-in block 203 located inside the placement slot 201 outward, and in the process of adsorption outward, the plug-in block 203 will pull the elastic rubber block 202 to deform. When the elastic rubber block 202 is deformed, the adsorption of the second electromagnet block 113 will cause the plug-in block 203 to gradually enter the inside of the plug-in slot 200. The plug-in block 203 is made of metal iron. When the plug-in block 203 gradually enters the plug-in slot The interior of 200 will cause a secondary clamping phenomenon between the plug-in block 203 and the plug-in slot 200. When the secondary clamping phenomenon 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 plug-in block 203 located inside the plug-in slot 200 can be tilted. When the plug-in block 203 is tilted, it can form abutment with the plug-in slot 200, thereby avoiding the separation of the first electromagnet block 108 and the second electromagnet block 113.

[0029] 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 by the adsorption force will rebound, thereby pulling the plug-in block 203 out of the plug-in slot 200 and returning the plug-in block 203 to its original position.

[0030] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in the present embodiment, the plug-in block 203 can be sucked into the interior of the plug-in slot 200 by the second electromagnet block 113 in the process of generating adsorption force, thereby forming a card connection phenomenon through the plug-in connection between the plug-in block 203 and the plug-in slot 200, further enhancing 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 plug-in block 203 can also be pulled back to the original position by the elastic rubber block 202, which will not affect the separation between the first electromagnet block 108 and the second electromagnet block 113 as a whole, thereby enhancing the overall stability.

[0031] Embodiment 3: Considering that it takes a certain amount of time for the plug-in block 203 to be pulled back to the original position by the elastic rubber block 202, after the first electromagnet block 108 and the second electromagnet block 113 lose their magnetic force and separate, the cable crane rope 102 with huge stress will instantly bounce off the two first electromagnet blocks 108 and the second electromagnet block 113. When the plug-in block 203 exists, the plug-in block 203 may not be completely restored to the original position during the rapid rebound of the cable crane rope 102 and may contact the cable crane rope 102, causing the cable crane rope 102 to hit the plug-in block 203. When the cable crane rope 102 is hit, it will affect the energy generated by the cable crane rope 102 when it is pressed down and rebounded, thereby affecting the rebound detection of the cable crane rope 102. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figure 4 As shown, a plurality of third electromagnet blocks 300 are integrally formed inside the second electromagnet block 113, and the third electromagnet block 300 is connected to the inside of the plug-in slot 200. The plurality of third electromagnet blocks 300 are located in the middle position of the second electromagnet block 113. The plurality of third electromagnet blocks 300 are used to be started before the first electromagnet block 108 is separated from the second electromagnet block 113, so that the second electromagnet block 113 generates a repulsive force before being separated from the first electromagnet block 108. When the second electromagnet block 113 is de-energized and loses its adsorption on the first electromagnet block 108, the repulsive force 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.

[0032] Specifically, during use, when it is necessary to separate the first electromagnet block 108 and the second electromagnet block 113, the multiple third electromagnet blocks 300 located inside the second electromagnet block 113 are pre-started and the power supply to the third electromagnet block 300 is a small power supply, so that only a small repulsive force occurs between the third electromagnet block 300 and the first electromagnet block 108, and the power supply needs to be maintained when the second electromagnet block 113 and the first electromagnet block 108 are still in the adsorption process, that is, the force of adsorption is much greater than the repulsive force generated by the third electromagnet block 300, and when separation is required, the power supply to the second electromagnet block 113 and the first electromagnet block 108 is canceled, and the power supply to the third electromagnet block 300 is instantly increased, so that sufficient repulsive force can be generated during the overall separation, and the power supply to the first electromagnet block 108 and the second electromagnet block 113 is canceled during the separation process, and the power supply to the third electromagnet block 300 is instantly increased. The steps of reducing the amount of power supplied to the first and second electromagnet blocks 108, 113 as a whole and increasing the amount of power to the third electromagnet block 300 are integrated in the same control operation button. First, the power supply to the first and second electromagnet blocks 108, 113 is cancelled, and then the power is increased instantly. The overall cancellation of power and the instantaneous increase of power are completed within 0.1 seconds to 0.3 seconds. During the separation of the first and second electromagnet blocks 108, 113, the repulsive force generated by the third electromagnet block 300 cooperates with the upward lifting force of the cable crane rope 102 to quickly separate the second and first electromagnet blocks 113, and drive the plug-in block 203 to quickly separate from the plug-in slot 200, so as to avoid the situation where the plug-in block 203 is not completely retracted and hits the cable crane rope 102 during the separation of the second and first electromagnet blocks 113, 108.

[0033] Furthermore, when the first electromagnet block 108 and the second electromagnet block 113 are separated, they will respectively generate a certain amount of swinging force to both sides, thereby reducing the collision with the cable crane rope 102. As a whole, no other device on the outside will collide with the cable crane rope 102, thereby avoiding inaccurate measurements caused by the collision.

[0034] like Figure 6As shown, a transverse vertical stick 600 is fixedly connected to one side adjacent to the two vertical walls 100, and two water tanks 601 are placed on both sides of the vertical walls 100. The water tank 601 is parallel to the positions of the first electromagnet block 108 and the second electromagnet block 113. The transverse vertical stick 600 and the water tank 601 are used to swing the first electromagnet block 108 and the second electromagnet block 113 into the water tank 601 with the transverse vertical stick 600 as the center point for winding when the first electromagnet block 108 and the second electromagnet block 113 are separated and swung to both sides in cooperation with the traction rope 110, and the downward swinging impact force generated by the first electromagnet block 108 and the second electromagnet block 113 is buffered by the water pool inside the water tank 601.

[0035] Specifically, during use, after the first electromagnet block 108 and the second electromagnet block 113 are separated, the cable hoist steel rope 102 separates the first electromagnet block 108 and the second electromagnet block 113 and then swings to both sides, and the traction rope 110 can be swung to the inside of the water storage tank 601 by setting the cross-section stand 600, and the water storage tank 601 stores water flow, and the swinging first electromagnet block 108 and the second electromagnet block 113 are buffered by the stored water flow, thereby reducing the first electromagnet block 108 and the second electromagnet block 113. Hitting other objects will cause excessive deformation, and the square movable light rod 111 is set behind the cross-sectional vertical stick 600 to prevent the splashing water 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 pulling force for the bottom and can be separated to both sides when separated. As a whole, the rebounding high-speed camera 112 will not produce excessive collision with other components, avoiding the collision from affecting the rebound of the cable crane rope 102, and further improving the stability and accuracy of the cable crane rope 102 during the detection process.

[0036] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the second embodiment, in the present embodiment, through the provision of the third electromagnet block 300, a repulsive force can be generated in advance through the third electromagnet block 300 in the middle part 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 in the process that the second electromagnet block 113 completely loses its magnetic force to adsorb the first electromagnet block 108, thereby quickly separating the first electromagnet block 108 and the second electromagnet block 113, and when quickly separating the second electromagnet block 113 and the first electromagnet block 108, the contact between the plug-in block 203 and the cable crane rope 102 can be avoided, thereby avoiding the phenomenon that the impact force generated when the cable crane rope 102 contacts the plug-in block 203 affects the rebound of the cable crane rope 102.

[0037] Embodiment 4: Considering that when the plug-in block 203 is inserted into the plug-in slot 200, and when the cable crane steel rope 102 rebounds, the plug-in block 203 will be tilted inside the plug-in slot 200, so that the plug-in block 203 is tilted inside the plug-in slot 200 to form a clamping connection, but after the inclined clamping connection is formed, when the first electromagnet block 108 and the second electromagnet block 113 need to be separated, the partially tilted clamping plug-in block 203 may be too tight, and when the plug-in block 203 is completely inserted into the plug-in slot 200, a deeper inclined clamping connection will be formed. When separated, the local plug-in block 203 will not be able to rebound to the original position in time, thereby causing the first electromagnet block 108 and the second electromagnet block 113 to partially remain clamped, affecting the rebound of the cable crane steel rope 102. In view of the above technical scheme, the present application proposes the following technical scheme, which is specifically: like Figure 5 As shown, a plurality of elastic ropes 400 are integrally formed inside the plug-in slot 200, and the elastic ropes 400 are used to provide a blocking rebound force when the plug-in block 203 is plugged into the plug-in slot 200. When the magnetic attraction 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 plugged in the plug-in slot 200 outward, thereby reducing the situation where the plug-in block 203 and the plug-in slot 200 are still stuck when the first electromagnet block 108 and the second electromagnet block 113 need to be separated.

[0038] Specifically, the arrangement of multiple elastic ropes 400 prevents the plug-in block 203 from being completely close to the inside of the plug-in slot 200, and during the plug-in process, the plug-in block 203 will squeeze the multiple elastic ropes 400 to cause the elastic ropes 400 to be deformed. When the elastic ropes 400 are deformed, a backward rebound force 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 rebound force generated by the deformation of the elastic rope 400 will not affect the plug-in block 203 from popping out of the inside of the plug-in slot 200. Instead, when the whole is separated, the second electromagnet block 113 no longer generates adsorption force on the plug-in block 203. When the adsorption force is no longer generated, the deformed elastic rope 400 will drive the plug-in block 203 to rebound to its original position, thereby accelerating the speed at which the plug-in block 203 rebounds to its original position and reducing the phenomenon that the plug-in block 203 is partially stuck and too tight inside the plug-in block 203.

[0039] like Figure 5As shown, the adjacent sides of the plug-in slot 200 and the plug-in block 203 are both tapered surfaces. The plug-in slot 200 and the plug-in block 203 with tapered surfaces can ensure that the plug-in slot 200 will not be skewed and stuck when plugged into the plug-in block 203, and the plug-in block 203 with a tapered surface can also cooperate with the elastic rope 400 to pop out the plug-in block 203 faster, avoiding the situation where the side wall of the plug-in block 203 is stuck inside the plug-in slot 200.

[0040] like Figure 6 As shown, buckles 700 are installed on the outside of the first electromagnet block 108 and the second electromagnet block 113 , a first pull rope 701 is connected to the buckle 700 located on the outside of the first electromagnet block 108 , and a second pull rope 702 is connected to the outside of the second electromagnet block 113 .

[0041] Specifically, the buckle 700 can be used to mechanically clamp the second electromagnet block 113 and the first electromagnet block 108 when they are not electromagnetically adsorbed, and the buckle 700 can be pulled open using the first pull rope 701 and the second pull 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.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
