Description

Technical Field

[0001] The utility model relates to the technical field of flaw detection, in particular to an online detection device for a steel wire rope of a port crane. Background Art

[0002] Generally, a wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, the wire rope can provide stable lifting, traction, tensioning and load-bearing required external forces. The wire rope has the advantages of high strength, light weight, stable operation and not easy to break suddenly. The reliable operation makes the application range of the wire rope wide and the application frequency high. Generally, the wire rope is used in the lifting and moving of heavier objects. Since the wire rope usually bears a large force during operation, it is easy to tear and be damaged due to tension, gravity and other forces. In order to improve the mechanical properties of the wire rope and reduce the accident rate, the working state of the wire rope needs to be regularly inspected. However, the internal mechanical damage of the wire rope is difficult to distinguish by the naked eye, so it is difficult to detect the damage of the wire rope, especially the damage detection of the wire rope of the crane.

[0003] The inventors have found that the existing wire rope damage detection has at least the following disadvantages:

[0004] Manual visual inspection has low efficiency and poor accuracy; all-in-one machine automated inspection requires the position of the all-in-one machine to be adjusted relative to the wire rope during installation, which is inconvenient to operate. Utility Model Content

[0005] The utility model aims to provide an online detection device for steel wire ropes of port cranes, which can reduce the difficulty of assembly, improve the assembly efficiency, improve the matching quality between the detection device and the steel wire rope, and improve the accuracy and reliability of the detection result.

[0006] The embodiment of the utility model is achieved as follows:

[0007] In a first aspect, the utility model provides an online detection device for a steel wire rope of a port crane, comprising:

[0008] The magnetic memory planning device and the weak magnetic detection device are designed in a split type. Both the magnetic memory planning device and the weak magnetic detection device are used to be installed on the frame and arranged at intervals. The magnetic memory planning device has a first channel for the steel wire rope to pass through, and the weak magnetic detection device has a second channel for the steel wire rope to pass through.

[0009] In an optional embodiment, the magnetic memory planning device includes a first base, a magnetic memory planning module and a first guide wheel group, the first base is connected to the frame, the magnetic memory planning module and the first guide wheel group are both installed on the first base; the first channel is arranged on the magnetic memory planning module; the first guide wheel group is used to limit the position of the wire rope in the first direction.

[0010] Based on the above scheme, the first base and the frame can be fixedly connected by bolts and other structural parts, and the magnetic memory planning module is installed on the first base, which is easy to install. The wire rope is limited by the first guide wheel group to prevent the wire rope from directly contacting the magnetic memory planning module and causing wear.

[0011] In an optional embodiment, the magnetic memory planning device also includes a first adjustment seat, which is connected to the first base, and the first adjustment seat can adjust the position relative to the first base in a second direction having an angle with the first direction, and the magnetic memory planning module is installed on the first adjustment seat.

[0012] Based on the above scheme, after the first base and the frame are installed, the preliminary positioning of the magnetic memory planning module and the steel wire rope is achieved, and then the magnetic memory planning module and the steel wire rope can be more tightly combined by adjusting the position of the first adjustment seat relative to the first base. For example, a strip hole can be set on the first adjustment seat, and bolts and other structural parts are passed through the strip hole, and the first adjustment seat is locked on the first base with bolts. When the position needs to be adjusted, loosen the bolt, move the first adjustment seat in the second direction, and adjust the position of the bolt in the strip hole. The operation is convenient. After the adjustment is completed, tighten the bolt to fix the first adjustment seat and the first base.

[0013] In an optional embodiment, the magnetic memory planning device also includes a second guide wheel group, which is installed on the first base. The second guide wheel group and the first guide wheel group are arranged at intervals to form a positioning space for the steel wire rope to pass through, and the first guide wheel group and the second guide wheel group are used to cooperate to limit the positions of the opposite sides of the steel wire rope.

[0014] Based on the above solution, the limiting effect of the wire rope is good through the cooperation of the first guide wheel group and the second guide wheel group.

[0015] In an optional embodiment, the magnetic memory planning device also includes a first oil baffle plate, which is provided with a first groove for the wire rope to pass through, and the first oil baffle plate is installed on the first base, and the first oil baffle plate is located on the side of the magnetic memory planning module away from the weak magnetic detection device.

[0016] Based on the above solution, the first oil baffle is designed to carry lubricating oil on the wire rope during its movement. When the amount of lubricating oil is large, part of it is scraped off by the first oil baffle, thereby preventing excessive oil from entering the magnetic memory planning module and affecting the normal use of the magnetic memory planning module.

[0017] In an optional embodiment, the weak magnetic detection device includes a second base, a weak magnetic detection module and a third guide wheel group, the second base is connected to the frame, and the weak magnetic detection module and the third guide wheel group are both installed on the second base; the second channel is arranged on the weak magnetic detection module; the third guide wheel group is used to limit the position of the wire rope in a third direction having an angle with the first direction.

[0018] Based on the above solution, the weak magnetic detection module is installed on the second base, and then installed on the frame through the second base, which is easy to install. The position of the wire rope can be limited by the third guide wheel group to avoid direct contact between the wire rope and the weak magnetic detection module, thereby improving the safety and reliability of operation.

[0019] In an optional embodiment, the weak magnetic detection device also includes a second adjustment seat, the second adjustment seat is connected to the second base, the second adjustment seat can adjust the position in the third direction relative to the second base, and the weak magnetic detection module is installed on the second adjustment seat.

[0020] Based on the above scheme, after the second base is installed on the frame, the weak magnetic detection module and the wire rope are initially positioned, and then the second adjustment seat is operated to move relative to the second base, and the second adjustment seat drives the weak magnetic detection module to move relative to the wire rope, so as to achieve fine adjustment of the position of the weak magnetic detection module and the wire rope, thereby improving the matching quality of the two. Among them, the second direction and the third direction can be designed to be consistent and perpendicular to the first direction.

[0021] In an optional embodiment, the third guide wheel group includes a third adjustment seat and a wheel body, the third adjustment seat is connected to the second base, the third adjustment seat can adjust the position in the third direction relative to the second base, the wheel body is installed on the third adjustment seat, and the wheel body is used to contact the wire rope to limit the position of the wire rope in the third direction.

[0022] Based on the above scheme, after the weak magnetic detection module is adjusted relative to the wire rope under the drive of the second adjustment seat, the third adjustment seat can be further operated to drive the wheel body to move relative to the wire rope, so that the relative positions of the wire rope, the wheel body and the weak magnetic detection module are more accurate. It should be noted that the magnetic memory planning device can be adjusted relative to the wire rope first, and then the weak magnetic detection device can be adjusted relative to the wire rope, or the order can be interchanged.

[0023] In an optional embodiment, the weak magnetic detection device also includes a second oil baffle plate, which is provided with a second groove for the steel wire rope to pass through, and the second oil baffle plate is installed on the second base and is located on the side of the weak magnetic detection module away from the magnetic memory planning device.

[0024] Based on the above solution, when the wire rope carries a lot of oil, it is blocked by the second oil baffle, reducing the probability of oil splashing into the weak magnetic detection module. The weak magnetic detection module has a good working environment, is not easily damaged, and has a long service life.

[0025] In an optional embodiment, the weak magnetic detection device further includes an oil receiving pan, which is mounted on the second base and is located below the second oil baffle plate to receive the oil falling from the second oil baffle plate.

[0026] Based on the above solution, the oil blocked by the second oil baffle falls into the oil receiving pan and is not easy to fall everywhere, which is not easy to pollute the environment or equipment, and can also play a role in recovering oil and improving resource utilization.

[0027] The beneficial effects of the embodiments of the utility model are:

[0028] In summary, the port crane wire rope online detection equipment provided in this embodiment, by setting the magnetic memory planning device and the weak magnetic detection device as a split structure, the two are installed independently without affecting each other, and during the installation process of the two, they can be independently adjusted according to the position of the wire rope without interfering with each other, with low operation difficulty and convenient installation, which effectively improves the installation efficiency and installation quality.

[0042] In the prior art, there are various types of automated equipment for detecting the wire rope 003 based on the magnetic memory planning method. However, the detection equipment currently on the market is all configured as an integrated structure, that is, the magnetic memory planning module and the weak magnetic detection module are both integrated together. During assembly, it is necessary to simultaneously adjust the positions of the magnetic memory planning module and the weak magnetic detection module relative to the wire rope 003. Since the wire rope 003 is generally tilted and has an angle, and due to factors such as space limitations, the assembly is difficult, inconvenient, and inefficient.

[0043] In view of this, the designer provides an online inspection device for the wire rope of a port crane, which can simplify the structure, reduce the difficulty of assembly, improve the assembly efficiency and quality, and facilitate the flaw detection of the wire rope 003.

[0044] Please combine Figure 1-Figure 4In this embodiment, the port crane wire rope online detection equipment includes a split-type magnetic memory planning device 100 and a weak magnetic detection device 200. The magnetic memory planning device 100 and the weak magnetic detection device 200 are both used to be installed on the frame 001 and arranged at intervals. The magnetic memory planning device 100 has a first channel 131 for the wire rope 003 to pass through, and the weak magnetic detection device 200 has a second channel 231 for the wire rope 003 to pass through.

[0045] Based on the above scheme, the assembly method of the port crane wire rope online detection device provided in this embodiment is as follows:

[0046] By setting the magnetic memory planning device 100 and the weak magnetic detection device 200 as a split structure, the two are installed independently without affecting each other, and during the installation process, they can be independently adjusted according to the position of the wire rope 003 without interfering with each other, and can each be highly matched with the wire rope 003, with low operation difficulty and convenient installation, which effectively improves the installation efficiency and quality.

[0047] The details of the online detection device for wire ropes of port cranes according to the embodiment of the present application are described below by way of examples.

[0048] Please combine Figure 1 and Figure 2In this embodiment, optionally, the port crane wire rope online detection equipment includes a split-type magnetic memory planning device 100 and a weak magnetic detection device 200, both of which are used to be installed on the frame 001 and arranged at intervals, and the magnetic memory planning device 100 has a first channel 131 for the wire rope 003 to pass through, and the weak magnetic detection device 200 has a second channel 231 for the wire rope 003 to pass through. During assembly, a guide wheel 002 for guiding the wire rope 003 is provided on the frame 001, and the wire rope 003 is wound around the guide wheel 002. The weak magnetic detection device 200 is located on the side of the frame 001 close to the guide wheel 002, and the magnetic memory planning device 100 is located on the side of the frame 001 away from the guide wheel 002. That is, the guide wheel 002, the weak magnetic detection device 200 and the magnetic memory planning device 100 are arranged in sequence. It should be understood that the steel wire rope 003 has two directions when it moves, one is the first direction of movement when it is wound on the wire drum, and the other is the second direction of movement when it is unwound from the wire drum. When the steel wire rope 003 moves, it can only be inspected in one direction by the magnetic memory planning device 100 and the weak magnetic detection device 200, that is, when the steel wire rope 003 moves, it needs to pass through the magnetic memory planning device 100 and then the weak magnetic detection device 200 before it can be inspected. How the steel wire rope 003 cooperates with the magnetic memory planning device 100 and the weak magnetic detection device 200 to realize the inspection belongs to the existing known technology. In order to avoid repeated description, it is not described in detail in this embodiment.

[0049] Please combine Figure 2 and Figure 3In this embodiment, optionally, the magnetic memory planning device 100 includes a first base 110, a first adjustment seat 120, a magnetic memory planning module 130, a first guide wheel group 140, a second guide wheel group 150 and a first oil baffle 160. The first base 110 is used to connect with the frame 001 through bolts and other structural parts, the magnetic memory planning module 130 is installed on the first adjustment seat 120, the first adjustment seat 120 is installed on the first base 110, and the first adjustment seat 120 can move relative to the first base 110, thereby driving the magnetic memory planning module 130 to move relative to the wire rope 003. The first guide wheel group 140 and the second guide wheel group 150 are both installed on the first base 110, and the two are arranged at intervals in the first direction, and a limited position space is formed between the two. The wire rope 003 is inserted in the limited position space, and the opposite sides of the wire rope 003 can be limited by the first guide wheel group 140 and the second guide wheel group 150 respectively, so that the movement range of the wire rope 003 in the first direction is limited. The first channel 131 is provided on the magnetic memory planning module 130. The first oil baffle 160 is provided with a first groove 161 for the steel wire rope 003 to pass through, and the first oil baffle 160 is installed on the first base 110, and the first oil baffle 160 is located on the side of the magnetic memory planning module 130 away from the weak magnetic detection device 200.

[0050] It should be understood that the first adjustment seat 120 and the first base 110 are slidably matched in a second direction perpendicular to the first direction. In this embodiment, the first direction is a vertical direction and the second direction is a horizontal direction. Obviously, in other embodiments, the angle between the first direction and the second direction may not be limited to 90°. Optionally, the first adjustment seat 120 is provided with a first bar hole 121 and a second bar hole 122, the first bar hole 121 extends in the first direction, and the second bar hole 122 extends in the second direction.

[0051] At the same time, during the movement of the steel wire rope 003, lubricating oil is carried on it. When the amount of lubricating oil is large, part of it is scraped off by the first oil baffle 160, thereby preventing excessive oil from entering the magnetic memory planning module 130 and affecting the normal use of the magnetic memory planning module 130. The steel wire rope 003 is located in the first groove 161, and the steel wire rope 003 has a large contact area with the groove wall of the first groove 161 in the circumferential direction, so the oil scraping effect is good.

The second base 210 is connected to the vehicle frame 001, and the weak magnetic detection module 230 is installed on the second adjustment base 220. The second adjustment base 220 and the second base 210 are slidably matched, so that the position of the weak magnetic detection module 230 relative to the wire rope 003 can be adjusted. The third guide wheel group 240, the second oil baffle plate 250 and the oil receiving pan 260 are all installed on the second base 210, and the oil receiving pan 260 is located below the second oil baffle plate 250. The second channel 231 is provided on the weak magnetic detection module 230. The third guide wheel group 240 is used to limit the position of the wire rope 003 in a third direction having an angle with the first direction, wherein the third direction is consistent with the second direction.

The second oil baffle plate 250 is installed on the second base 210 and is located on the side of the weak magnetic detection module 230 away from the magnetic memory planning device 100. When the steel wire rope 003 carries a lot of oil, it is blocked by the second oil baffle plate 250, which reduces the probability of oil splashing into the weak magnetic detection module 230. The weak magnetic detection module 230 has a good working environment, is not easy to be damaged, and has a long service life. The oil blocked by the second oil baffle plate 250 falls into the oil receiving pan 260, is not easy to pollute the environment, and can achieve the reuse of oil.

[0053] Optionally, the second adjustment seat 220 and the second base 210 can be slidably matched in the second direction, and a third strip hole 221 and a fourth strip hole 222 can be set on the second adjustment seat 220.

[0055] In other embodiments, optionally, the weak magnetic detection device 200 and the magnetic memory planning device 100 are arranged in pairs and adjusted accordingly according to the number of steel wire ropes 003. When it is necessary to perform flaw detection on multiple steel wire ropes 003 at the same time, multiple pairs of weak magnetic detection devices 200 and magnetic memory planning devices 100 can be set. For example, in this embodiment, the weak magnetic detection device 200 includes two weak magnetic detection modules 230, and correspondingly, the magnetic memory planning device 100 includes two magnetic memory planning modules 130.
