Description

Technical Field

[0001] The present invention relates to the technical field of wire rope detection, and specifically to a wire rope detection device for a port crane. Background Art

[0002] A port crane is a device used for loading and unloading goods at a wharf. In most cases, a port crane is composed of a wire rope, a slewing mechanism, a luffing mechanism, and a control system, etc. After long-term operation of the port crane, the wire rope will be damaged to varying degrees, which will not only affect the lifting operation but also may cause accidents. Therefore, a professional wire rope detection system and wire rope detection device are required to detect the wire rope on the port crane.

[0003] Chinese Patent CN215180155U discloses a wire rope detection device and a wire rope detection system for a port crane, including a detection unit for detecting the wire rope; a positioning member for being installed on the frame of the port crane, and the positioning member is configured to extend along a direction perpendicular to the running direction of the wire rope; a first connecting member for connecting the positioning member and the detection unit, and the first connecting member is configured to be slidably matched with the positioning member. When the detection unit sways with the wire rope, the first connecting member can slide relative to the positioning member. The wire rope detection device of this application sets a positioning member to play a role in shock absorption and limit for the detection unit.

[0004] The wire rope detection device and the wire rope detection system for a port crane in the above-mentioned disclosed prior art also have a support assembly. Although the support assembly can play a role in supporting and guiding the wire rope, after long-term operation, the support assembly will be worn, which will cause the wire rope to sway greatly during the detection process. First, it will reduce the accuracy of the detection result. Second, the swaying wire rope will cause a whipping phenomenon to the detection device, resulting in damage to the detection device. In addition, after the wire rope has been used for a long time, there will be a phenomenon of broken wires. Generally, before detecting the wire rope, the warped broken wires will be removed. However, during the process of removing the broken wires of the wire rope, not only time and manpower are wasted, but there may also be missed broken wires that are not processed cleanly. During the subsequent detection process, since the wire rope is constantly moving, the missed warped broken wires will also whip the detection device, causing damage to the detection device.

[0005] In view of the above problems, a wire rope detection device for a port crane is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a port crane wire rope detection device.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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.

[0040] To solve the technical problems that during the detection process, the support component 3 wears out, and the steel wire rope 10 shakes significantly, resulting in a reduction in the accuracy of the detection results and damage to the magnetic memory planning component 5 and the flaw detector 6, as Figure 1 - Figure 14 shown, the following preferred technical solutions are provided:

[0041] The steel wire rope detection system for a port crane includes a controller 1 and a monitoring module 20.

[0042] A steel wire rope detection device for a port crane includes a detection device 30. The detection device 30 includes a mounting component 2, a support component 3, an anti-damage component 4, a magnetic memory planning component 5, a flaw detector 6, a collection module 7, an alarm module 8, and a processing module 9. A steel wire rope 10 is drivingly arranged on the support component 3, and the steel wire rope 10 passes through the interiors of the anti-damage component 4, the magnetic memory planning component 5, and the flaw detector 6.

[0043] The mounting component 2 serves to support and fix each component. The support component 3 serves to support and limit the steel wire rope 10, preventing the steel wire rope 10 from shaking violently during the detection process and whipping the magnetic memory planning component 5 and the flaw detector 6, thereby affecting the accuracy of the detection results and causing damage to the magnetic memory planning component 5 and the flaw detector 6. Before detecting the steel wire rope 10, a memory magnetic field needs to be formed on the steel wire rope 10 through the magnetic memory planning component 5, and then the flaw detector 6 is used to detect the defects of the steel wire rope 10. The anti-damage component 4 prevents the broken wires omitted on the steel wire rope 10 from not being processed cleanly and whipping the magnetic memory planning component 5 and the flaw detector 6 during subsequent detection, thereby avoiding the problem of damage to the magnetic memory planning component 5 and the flaw detector 6. The collection module 7 collects the detection data and uploads the collected detection data to the processing module 9 for analysis. If the detection data is qualified, the detection continues. If the detection data is unqualified, the controller 1 activates the alarm module 8 to give an alarm.

[0044] The installation component 2 includes an installation plate 21 and connecting pieces 22 fixedly installed at both ends of the installation plate 21 respectively. The installation plate 21 is provided with a plurality of relief grooves 23. The installation plate 21 is used to support and position each component. The connecting pieces 22 are used to fixedly connect the installation plate 21 to the port crane, and then install the entire detection device 30 of the steel wire rope 10 on the port crane. The setting of the relief grooves 23 is to enable the support component 3 to be reasonably installed.

[0045] The support component 3 includes a first limiting member 31 fixedly installed on the installation plate 21. An installation frame 32 is also fixedly installed on the installation plate 21. A second limiting member 33 is fixedly installed on the installation frame 32. The steel wire rope 10 passes through the gap between the first limiting member 31 and the second limiting member 33. The first limiting member 31 and the second limiting member 33 can support and position the steel wire rope 10, preventing the steel wire rope 10 from shaking violently during the detection process.

[0046] The first limiting member 31 includes a pair of fixing plates 311 fixedly installed on the installation plate 21. The two fixing plates 311 are arranged symmetrically. Sector-shaped baffles 312 are respectively fixedly installed on the inner side walls of the two fixing plates 311. An F-shaped bracket 313 is fixedly installed on the outer wall of one side of the installation plate 21. A motor 314 is fixedly installed on the F-shaped bracket 313. The output end of the motor 314 penetrates through one of the sector-shaped baffles 312. The motor 314 has a braking function. Long strip plates 315 are respectively rotatably installed on the inner side walls of the two sector-shaped baffles 312. A pair of first clamping components 316 are respectively arranged through and slidably on the side walls of the two long strip plates 315. A pair of second clamping components 318 are arranged at the gap between the two sector-shaped baffles 312. A clamping relationship can be formed between the second clamping components 318 and the first clamping components 316. When two of the first clamping components 316 are flipped to the gap between the two sector-shaped baffles 312, the two sector-shaped baffles 312 will apply pressure to these two first clamping components 316, causing the two first clamping components 316 to move towards the inside of the second clamping components 318. Pulleys 317 are respectively clamped on the circumferential outer walls of the two second clamping components 318.

[0047] During the detection of the steel wire rope 10, since the steel wire rope 10 is constantly moving, and since the steel wire rope 10 is in contact with the outer wall of the pulley 317 on the upper half of the long strip plate 315, when the steel wire rope 10 moves, it will drive the pulley 317 on the upper half of the long strip plate 315 to rotate. At this time, the pulley 317 and the second clamping member 318 are in a clamped state. Therefore, the pulley 317 will drive the second clamping member 318 to rotate synchronously on the two first clamping components 316, changing the friction between the pulley 317 and the steel wire rope 10 into rolling friction, which is beneficial to reducing wear. When the pulley 317 and the second clamping member 318 rotate for a long time, the wear gap between the first clamping component 316 and the second clamping member 318 will become larger and larger, and then the pulley 317 and the second clamping member 318 will have a position deviation, making the supporting and limiting effects of the pulley 317 on the steel wire rope 10 worse, and then causing the steel wire rope 10 to shake greatly during the movement.

[0048] The first clamping component 316 includes a clamping post 3161 slidably installed through the side wall of the long strip plate 315. The clamping post 3161 is elastically connected to the outer side wall of the long strip plate 315 through a first spring 3162. A bearing 3163 is fixedly sleeved on the circumferential side wall of one end of the clamping post 3161 close to the second clamping member 318, and a convex block 3164 is fixedly installed on the side wall of one end of the clamping post 3161 close to the second clamping member 318.

[0049] The pulley 317 includes a wheel body 3171, and a pair of clamping grooves 3172 are opened in the inner cavity of the wheel body 3171. A clamping relationship can be formed between the clamping grooves 3172 and the second clamping member 318.

[0050] The sector baffle 312 includes a sector baffle main body 3121 fixedly installed on the inner side wall of the fixing plate 311, and an arc surface 3122 is arranged at the bottom of the sector baffle main body 3121.

[0051] The second clamping member 318 includes an installation cylinder 3181. A pair of deep grooves 3182 are opened on the circumferential outer wall of the installation cylinder 3181. A top post 3183 is slidably inserted through the inner cavities of the two deep grooves 3182 respectively. The top post 3183 is elastically connected to the side wall of the inner cavity of the deep groove 3182 through a second spring 3184, and a clamping relationship can be formed between the top post 3183 and the clamping groove 3172. Two pairs of sliding grooves 3189 are opened on the side wall of the inner cavity of the installation cylinder 3181. A sliding plate 3185 is slidably embedded in the inner cavities of the two sliding grooves 3189 respectively. A pair of circular grooves 3188 are also opened on the side wall of the inner cavity of the installation cylinder 3181. The sliding plate 3185 is elastically connected to the side wall of the inner cavity of the circular groove 3188 through a third spring 3186. A groove 3187 is opened on the outer side wall of the sliding plate 3185, and the groove 3187 is arranged in alignment with the convex block 3164.

[0052] Specifically, as Figure 8As shown, in the initial state, the top column 3183 at the upper half of the long strip 315 is snapped into the inside of the card slot 3172 under the elastic action of the second spring 3184, so that the pulley 317 and the second clamping part 318 at the upper half of the long strip 315 are combined into a whole. Under the extrusion of the sector baffle 312 on the clamping column 3161, the convex block 3164 on the clamping column 3161 is snapped into the inside of the groove 3187, and the sliding plate 3185 is attached to the side wall of the inner cavity of the mounting cylinder 3181. At this time, the bearing 3163 on the clamping column 3161 is in the inner cavity of the wheel body 3171 and abuts against the side wall of the mounting cylinder 3181; during the detection of the steel wire rope 10, the moving steel wire rope 10 drives the pulley 317 and the second clamping part 318 to rotate synchronously. Since the bearing 3163 abuts against the side wall of the mounting cylinder 3181, under the action of friction, the pulley 317 and the second clamping part 318 will rotate on the clamping column 3161 through the bearing 3163. The setting of the bearing 3163 can reduce the wear between the mounting cylinder 3181 and the clamping column 3161. Through the above setting, the friction between the pulley 317 and the steel wire rope 10 is changed into rolling friction, which is beneficial to reducing wear.

[0053] Further, when the pulley 317, the second clamping part 318 and the bearing 3163 at the upper half of the long strip 315 are worn after a long time of rotation, the wear gap between the pulley 317, the second clamping part 318, the bearing 3163 and the clamping column 3161 becomes larger and larger, which will cause the position deviation of the pulley 317 and the second clamping part 318, and the supporting and limiting effects of the pulley 317 on the steel wire rope 10 become worse. As a result, the steel wire rope 10 shakes greatly during the movement. At this time, the motor 314 is started to rotate 180°. The first clamping assembly 316, the pulley 317 and the second clamping part 318 at the upper half of the long strip 315 are turned to the lower part, and at the same time, the first clamping assembly 316, the pulley 317 and the second clamping part 318 at the lower half of the long strip 315 will be turned to the upper part for replacement. Since the motor 314 has a braking function, during the detection process, the long strip 315 will not drive the first clamping assembly 316, the pulley 317 and the second clamping part 318 to flip randomly, and thus can play a role in supporting and limiting the steel wire rope 10. Through the above setting, when the first clamping assembly 316, the pulley 317 and the second clamping part 318 at the upper half of the long strip 315 have position deviation and insufficient support due to wear, the worn first clamping assembly 316, the pulley 317 and the second clamping part 318 can be replaced, and the whole replacement process does not require shutdown operation, which is beneficial to improving the working efficiency of the port crane.

[0054] Furthermore, as Figure 9As shown, during the process that the motor 314 drives the clamping assembly 1 316, the pulley 317 and the clamping member 2 318 at the upper part of the long plate 315 to flip, when the clamping assembly 1 316, the pulley 317 and the clamping member 2 318 at the upper part of the long plate 315 leave the fan-shaped baffle body 3121, the fan-shaped baffle body 3121 withdraws the force on the clamping column 3161, and under the elastic force of the spring 1 3162, it will drive When the cam 3185 is in the state of being moved out of the way, the cam 3185 will be in the state of being moved out of the way and the cam 3185 will be in the state of being moved out of the way. , until it abuts against the inner wall of the fan-shaped baffle body 3121. At this time, the protrusion 3164 on the clamping column 3161 is inserted into the interior of the groove 3187, and the slide plate 3185 is fitted with the side wall of the inner cavity of the mounting cylinder 3181. The bearing 3163 on the clamping column 3161 is in the inner cavity of the wheel body 3171 and abuts against the side wall of the mounting cylinder 3181. At this point, the replacement operation is completed, and the wire rope 10 can continue to be supported and limited.

[0055] Through the above-mentioned replacement operation, the worn clamping component 1 316, the pulley 317 and the clamping component 2 318 that are located in the upper part of the long plate 315 can be replaced in time, and the swing amplitude of the wire rope 10 can be reduced in time, and the phenomenon of the wire rope 10 whipping the magnetic memory planning component 5 and the flaw detector 6 can be avoided as much as possible, which plays a role in protecting the magnetic memory planning component 5 and the flaw detector 6 and is conducive to maintaining good detection accuracy.

[0056] When the worn pulley 317 needs to be replaced, the staff uses a tool to pull the clamping post 3161, and withdraws the convex block 3164 from the inside of the groove 3187. The clamping relationship between the convex block 3164 and the groove 3187 is released. At this time, the second clamping part 318 and the pulley 317 will fall off from the first clamping assembly 316. Then the staff presses the installation cylinder 3181 forcefully. Since the clamping end of the ejector pin 3183 is arc-shaped, when the appropriate pressing force is reached, the ejector pin 3183 will slide out from the inside of the clamping groove 3172, and then the clamping relationship between the ejector pin 3183 and the clamping groove 3172 is released. At this time, the worn pulley 317 can be removed from the second clamping part 318. Then a new pulley 317 is installed on the second clamping part 318, and the clamping relationship between the ejector pin 3183 and the clamping groove 3172 is restored again. Then the second clamping part 318 is installed on the first clamping assembly 316, and the clamping relationship between the convex block 3164 and the groove 3187 is restored again. The above operations replace the worn pulley 317 without affecting the detection and hoisting process of the steel wire rope 10, which is beneficial to improving work efficiency. Moreover, adopting the above disassembly and assembly method can quickly disassemble and install the worn pulley 317, which not only has a high replacement efficiency, but also is easy to operate and saves manpower.

[0057] In order to solve the technical problems that after the steel wire rope 10 has been used for a long time, there are broken wires that are not cleaned up, and during the subsequent detection process, the magnetic memory planning component 5 and the flaw detector 6 are whipped, resulting in damage to the magnetic memory planning component 5 and the flaw detector 6 and affecting the detection accuracy, as Figure 2 and Figure 15 - Figure 17 shown, the following preferred technical solutions are provided:

[0058] The anti-damage component 4 includes a sleeve 41 fixedly installed on the mounting plate 21. A spiral track 42 is arranged on the side wall of the inner cavity of the sleeve 41. A moving cylinder 43 is slidably installed in the spiral track 42 in an embedded manner. A driving member 45 is arranged inside the moving cylinder 43. A pair of welding assemblies 44 are fixedly installed on the side wall of the inner cavity of the moving cylinder 43, and the two welding assemblies 44 are arranged symmetrically.

[0059] The welding assembly 44 includes a protective shell 441 fixedly installed on the side wall of the inner cavity of the moving cylinder 43, which plays a role in protecting the components inside the protective shell 441 and preventing the broken wires of the steel wire rope 10 from damaging the components inside the protective shell 441. An electric telescopic column 442 is fixedly installed inside the protective shell 441. The output end of the electric telescopic column 442 is fixedly connected with an arc-shaped pressing plate 443. A welding electrode 444 is fixedly installed on the side wall of the output end of the electric telescopic column 442.

[0060] The driving member 45 includes a servo motor 451 embedded and fixedly installed inside the moving cylinder 43 . The output end of the servo motor 451 is fixedly connected to a roller 452 . The roller 452 is embedded and rollingly arranged on the spiral track 42 .

[0061] Specifically, Figure 16 and Figure 17 As shown, when the monitoring module 20 determines that the broken wire on the wire rope 10 has not been cleaned up, when the broken wire passes over the arc pressure plate 443, the controller 1 controls the two electric telescopic columns 442 to extend until the two arc pressure plates 443 are pressed on the surface of the wire rope 10, and the two arc pressure plates 443 just form a hollow circle, and then the servo motor 451 is started to drive the roller 452 to rotate. Since the roller 452 is embedded and rolled on the spiral track 42, when the roller 452 rolls on the spiral track 42, it will synchronously drive the moving cylinder 43 to rotate on the spiral track 42, thereby making the moving cylinder 43 move forward on the sleeve 41. Since the moving cylinder 43 moves forward at a speed greater than the steel wire rope 10, the moving cylinder 43 can move forward on the sleeve 41. If the moving speed of the wire rope 10 is fast, the two arc-shaped pressure plates 443 will straighten the raised broken wires and press the straightened broken wires. In the process of the two arc-shaped pressure plates 443 straightening the raised broken wires, the broken wires are simultaneously welded to the surface of the wire rope 10 through the welding electrodes 444. This ensures that there will be no raised broken wires on the wire rope 10 before it enters the magnetic memory planning component 5 and the flaw detector 6, and the broken wires will not whip the magnetic memory planning component 5 and the flaw detector 6. This protects the magnetic memory planning component 5 and the flaw detector 6, prevents the magnetic memory planning component 5 and the flaw detector 6 from being damaged, and is conducive to maintaining good detection accuracy.
