The present invention cooperates with a detection part, a straightening part one and a straightening part two. After detecting a wire rope that is bent but has not reached a scrap standard, the wire rope is straightened by the straightening part one and the straightening part two, and then the straightened wire rope is detected again by the detection part to ensure that the wire rope is no longer bent, thereby improving the service life of the wire rope and not affecting the detection result of whether the wire rope is scrapped, thereby preventing it from affecting the normal use of the port door crane. The cleaning sponge cleans the surface of the wire rope and guides and limits it to make it centered between the semicircular ring plates to prevent the wire rope from being bent. When the wire rope is not centered, its bent part contacts the detection element on the semicircular ring plate, thereby damaging the detection element and the wire rope.

Description

Technical Field

[0001] The present invention relates to the technical field of port gantry crane detection, and in particular to a port gantry crane detection device and a detection method. Background Art

[0002] The port gantry crane is a rotating arm crane that performs lifting and loading and unloading operations. The wire rope on the port gantry crane plays an important role in the use of the port gantry crane. Therefore, its quality determines whether the port gantry crane can be used normally. In order to ensure the safety and efficient operation of the port operation, the wire rope of the port gantry crane needs to be tested.

[0003] The traditional wire rope inspection method is to pass the wire rope through the inspection device and then inspect it through the inspection element to obtain the inspection data. During the use of the port gantry crane, the wire rope will have defects such as wear, rust, broken wires and bending. If any of the defects exceeds the scrap judgment standard, it can be scrapped and replaced. Among them, the degree of wire rope bending defects gradually becomes more serious with the increase of usage time. If only inspection is carried out without auxiliary straightening, the service life of the wire rope will be greatly shortened. When the wire rope is bent, the wire rope is not centered, and the contact between the bent part and the detection element may damage the detection element, affecting the inspection results and even affecting the normal use of the port gantry crane.

[0037] See Figure 1 The installation unit 1 includes a fixed bracket 11. The lower end of the arm of the port gantry crane is fixedly installed with the fixed bracket 11 by bolts. An electric slide rail 12 is fixedly installed in the middle of the fixed bracket 11. The left end of the electric slider on the electric slide rail 12 is fixedly installed with a fixed block 13. Support plates 14 are fixedly installed at the upper and lower ends of the fixed block 13. The support plates 14 on the upper and lower sides have different areas. The support plates 14 are both connected to the fixed bracket 11 for upward and downward sliding.

[0038] See Figure 3 and Figure 4The detection unit 21 includes a horseshoe-shaped shell 211. Two horseshoe-shaped shells 211 are provided at the left end of the fixed block 13. The horseshoe shells 211 are symmetrically arranged on the left and right sides. The left end of the fixed block 13 is fixedly connected to the adjacent horseshoe-shaped shell 211. The left and right horseshoe shells 211 are fixedly connected by bolts. The opposite ends of the two horseshoe shells 211 are rotatably connected with semi-circular ring gears 212. The semi-circular ring gears 212 on the left and right sides are fixedly connected by bolts. A spur gear 213 is rotatably connected to the horseshoe shell 211 on the left side. The spur gear 213 is meshed with the adjacent semi-circular ring gear 212. The opposite ends of the two semi-circular ring gears 212 are fixedly installed A semicircular ring plate 214 is installed, and multiple detection elements 215 are fixedly installed at the opposite ends of the semicircular ring plate 214. The multiple detection elements 215 are evenly arranged along the spiral path. The lower support plate 14 is provided with a signal processing circuit, an output interface and a data processing unit. The detection element 215 is electrically connected to the signal processing circuit, the signal processing circuit is electrically connected to the output interface, and the output interface is electrically connected to the data processing unit. The detection unit 215 is specifically an electromagnetic sensor, which mainly works based on the principle of electromagnetic induction. It relies on the electromagnetic sensor to receive electromagnetic wave information and convert it into electrical signals to judge the bending, broken wire, wear and rust condition of the wire rope.

[0039] See Figure 2 and Figure 4 The limiting portion 31 includes a limiting guide plate 311. The limiting guide plates 311 are fixedly installed on the upper and lower ends of the semicircular ring plate 214. The limiting guide plates 311 are connected to the movable bracket 312 on the end away from the horseshoe-shaped shell 211 for sliding left and right. The limiting guide plate 311 is fixedly installed with a limiting guide block 313 on the end facing the corresponding horseshoe-shaped shell 211. Annular grooves with a right angle central angle are symmetrically opened on the upper and lower ends of the horseshoe shell 211, and the limiting guide block 313 is slidably connected to the corresponding annular groove.

[0040] See Figure 2 The contact portion 33 includes a fan-shaped plate 331, and the fan-shaped plates 331 are fixedly installed on the opposite ends of the left and right opposite movable brackets 312. A plurality of cylindrical springs 332 are fixedly installed on the opposite ends of the left and right opposite fan-shaped plates 331. The plurality of cylindrical springs 332 are evenly arranged along the circumferential direction. The cylindrical springs 332 on the same side are fixedly installed with a fan-shaped limiting plate 333 at one end away from the fan plate 331. A cleaning group is fixedly installed on the opposite ends of the left and right opposite limiting plates 333. The cleaning group is composed of fan-shaped cleaning sponges 334 arranged symmetrically up and down.

[0041] At this time, the motor of the external device drives the spur gear 213 to rotate, thereby driving the semi-circular ring gear 212, the movable bracket 312 and the semi-circular ring plate 214 to rotate together, and the cleaning sponge 334 on the limit plate 333 cleans the surface of the wire rope comprehensively. Under the elastic force of the cylindrical spring 332, the cleaning sponge 334 on the limit plate 333 is ensured to be in close contact with the wire rope. While cleaning the surface of the wire rope, the wire rope is guided and limited so that it is centered between the semi-circular ring plates 214 to prevent the wire rope from bending. Because the rope is not centered, its bent part contacts the detection element 215 on the semicircular ring plate 214, thereby damaging the detection element 215 and the wire rope. When the detection element 215 detects the wire rope, the port door crane is started to control the wire rope to extend downward for detection. The electromagnetic sensor serving as the detection element 215 converts the received electromagnetic wave information into an electrical signal through the signal processing circuit, and then outputs the electrical signal to the data processing unit through the output interface. After receiving the data, the receiving end of the data processing unit processes and analyzes it.

[0042] See Figure 2 and Figure 3 The distance control part 32 includes a rectangular block 321, and a rectangular block 321 is fixedly installed at the front end of the limiting guide plate 311. A bidirectional screw 322 is connected to the two rectangular blocks 321 opposite to each other and rotates together. The left and right corresponding movable brackets 312 are symmetrically threaded with the bidirectional screw 322. A limiting guide rod 323 is fixedly installed on the left end of the right movable bracket 312, and an anti-falling block is threadedly connected to the left end of the limiting guide rod 323. A blocking block is provided on the limiting guide rod 323, and the left side of the limiting guide rod 323 slides through the corresponding movable bracket 312 on the left.

[0043] See Figure 2 and Figure 4 The straightening linkage part 41 includes a bevel gear 411, and the left end of the upper support plate 14 is rotatably connected to the bevel gear 411 through a bracket. The left end of the upper support plate 14 is rotatably connected to the bevel gear 412 meshing with the bevel gear 411 through a bracket. The right end of the bevel gear 411 is fixedly mounted with a pulley 413, and the left end of the upper support plate 14 is rotatably connected to the pulley 414. The pulley 413 and the pulley 414 are connected through a belt 415.

[0044] See Figure 3 and Figure 5The straightening part 42 includes a two-way screw 421, and the rear end of the bevel gear 412 is fixedly installed with a two-way screw 421. The rear side of the two-way screw 421 is rotatably connected to the support plate 14 on the upper side through a bracket. The two-way screw 421 is symmetrically threaded with a support block 422 front and back. The corresponding support blocks 422 on the left and right rotate together and are connected to the straightening roller 423 symmetrically arranged up and down. The left end of the front support block 422 is symmetrically connected to the straightening roller 423 for rotation. The middle end of the straightening roller 423 is provided with an annular groove with a semicircular cross-section.

[0045] If the data after analysis during the inspection process shows that the wire rope has no bending, broken wires, wear and rust, the non-destructive inspection of the wire rope is qualified. When the wire rope has any one to four conditions of bending, broken wires, wear and rust, the inspection data will be compared with the standard data for damage judgment. If the inspection data are all less than the standard data, the wire rope can continue to be used. If any one of the data is greater than the standard data, the wire rope will be scrapped and replaced with a new one. During the inspection process, if the wire rope has a bending defect and the bending degree data is less than the standard data for bending scrap judgment, the electric slider will drive the fixed block 13 to move down until the straightening roller 4 23 is close to the bend, and the bidirectional screw 2 421 is driven to rotate by the external motor 2. With the cooperation of the bevel gear 1 411 and the bevel gear 2 412, the bidirectional screw 2 421 on the straightening part 2 43 rotates synchronously, so that the straightening rollers 423 are in close contact with the wire rope. At this time, the electric slider continues to drive the fixed block 13 to move downward, so that the straightening rollers 423 straighten the bent part of the wire rope. After straightening, the fixed block 13 is driven to move up to the initial position by the electric slider. At this time, the straightened wire rope is continued to be tested by the detection element 215 to ensure that the wire rope is no longer bent, and then the detection is continued until the wire rope stretched to the longest state is tested.

[0046] Continue reading Figure 3 and Figure 5 The mating part 44 includes a threaded column 441, and the left end of the support block 422 on the rear side of the bidirectional screw 421 is symmetrically connected to the straightening roller 423 through the threaded column 441. The threaded column 441 is threadedly connected to the support block 422 on the rear side of the bidirectional screw 421. The rear side of the limiting guide rod 425 is connected to the support block 422 for forward and backward sliding. The support block 422 on the limiting guide rod 425 is rotatably connected to the corresponding straightening roller 423 symmetrically connected to the right side.

[0047] See Figure 3 The structure of the straightening part 43 is the same as that of the straightening part 1 42, except that the directions of the parts are perpendicular to each other. The left end of the pulley 2 414 is fixedly connected to the bidirectional screw 2 421 on the straightening part 2 43. The matching part 2 45 includes a right-angle bracket 451. The left end of the upper support plate 14 is fixedly connected to the right-angle bracket 451 by bolts. The vertical section of the right-angle bracket 451 is connected to the limiting guide rod 2 425 on the matching part 2 45 for left and right sliding.

[0048] Nothing is hung on the hook on the wire rope of the port gantry crane. The horseshoe-shaped shells 211 on the left and right sides of the fixed bracket 11 that has not been installed are separated. Under the limit of the bidirectional screw 322, the distance between the left and right limit plates 333 and the left and right semicircular ring plates 214 are at their maximum.
