Description

Technical Field

[0001] This invention relates to the field of wire rope technology, and in particular to a wire rope inspection and maintenance device for a gantry crane. Background Technology

[0002] like Figure 1 As shown, the gantry crane 700 has a large external dimension and operates outdoors for extended periods. Combined with the lifting tension, the surface and internal lubricant of the lifting wire rope 400 will gradually decrease, weakening its resistance to external corrosion and leading to corrosion. Improper use can also cause excessive localized wear, strand breakage, or broken wires in the lifting wire rope 400, seriously threatening the safety of the lifting process and necessitating timely disposal. Therefore, it is essential to conduct regular comprehensive inspections and maintenance of the wire rope 400 of the gantry crane 700 according to relevant industry regulations to ensure that the lifting wire rope 400 is in a safe condition.

[0003] One end of the wire rope 400 is fixed to the fixed end 300 below the end of the lifting beam 200, and the other end is connected to the winch 100 through the movable pulley 500 and the fixed pulley block. The wire rope 400 drives the movable pulley 500 to lift and lower (meeting the lifting requirements) by rotating the winch 100 in both directions.

[0004] Although regular inspection and maintenance of the wire rope 400 of the gantry crane 700 can be performed at the winch 100 or on the ground, a portion of the wire rope 400 will always be unable to return to the winch 100 position. Furthermore, due to the structural characteristics of the gantry crane 700, the end of the lifting beam 200 cannot be lowered to the ground (it remains at a high altitude). This necessitates high-altitude inspection and maintenance of the end of the wire rope 400 connected to the fixed end 300 below the end of the lifting beam 200. Figure 1 As shown, the area of ​​the wire rope 400 near the fixed end 300 is the difficult area 400A.

[0005] The existing technology involves using a separate crane to gradually lift the inspection and maintenance personnel (who stand in a special cage) from the ground to a high altitude. During the lifting process, the personnel manually inspect and maintain the difficult areas 400A of the wire rope 400. However, this method requires the use of a crane, resulting in high costs, difficult inspection and maintenance, and a high risk of manual high-altitude work. Summary of the Invention

[0041] As shown in Figures 1-10 The present embodiment provides a wire rope inspection and maintenance device of a portal crane. The wire rope 400 is arranged at a fixed end 300 of a suspension beam 200 of the portal crane 700, and the other end of the wire rope 400 is connected to a winch 100 through a movable pulley 500. The inspection and maintenance device 600 comprises a body assembly 1, a scraping oil assembly 2 and a camera 3. The body assembly 1 comprises a first connecting pipe 11, a first flared mouth structure 12 and a second flared mouth structure 13 connected to both ends of the first connecting pipe 11. The inner diameter of the first connecting pipe 11 is greater than the outer diameter of the wire rope 400, and the wire rope 400 can be arranged in the first flared mouth structure 12, the first connecting pipe 11 and the second flared mouth structure 13. The body assembly 1 can be fixed to the outer shell 510 of the movable pulley 500, and the winch 100 is rotated to move the body assembly 1. The first flared mouth structure 12 is used to accommodate the grease 10. The scraping oil assembly 2 is arranged in the first flared mouth structure 12, and when the body assembly 1 moves downward, the scraping oil assembly 2 is used to scrape off the excess grease 10 on the wire rope 400. The camera 3 is arranged in the first flared mouth structure 12, and the camera 3 is used to shoot the position above the scraping oil assembly 2 and transmit the shooting information back to the terminal information receiving device.

[0042] The preparation work of using the wire rope inspection and maintenance device of the portal crane includes the following steps: the body assembly 1 is sleeved on the wire rope 400, and the body assembly 1 is fixed to the outer shell 510 of the movable pulley 500, wherein the first flared mouth structure 12 faces upward, the second flared mouth structure 13 faces downward, and the scraping oil assembly 2 and the camera 3 are located at the preset position. Turn on all the cameras 3 and the terminal information receiving device (such as a mobile phone or a computer), and adjust the up-down angle of the camera 3, such as the position of the camera 3 for shooting is 30mm-50mm away from the scraping oil assembly 2, such as 30mm, 40mm or 50mm, etc. Check the image checking effect on the screen of the terminal information receiving device until the real state of the wire rope 400 can be clearly and completely observed. Then, place enough grease 10 (just submerge the top of the scraping oil assembly 2) into the first flared mouth structure 12 of the inspection and maintenance device 600.

[0043] The method for automatic inspection using the steel wire rope inspection and maintenance device of the portal crane comprises the following steps: the winch 100 rotates in one direction (for example, forward), the body assembly 1 moves upward along the steel wire rope 400, the camera 3 photographs the steel wire rope 400, the terminal information receiving device receives the photographing information in real time through the real-time photographing and transmitting of the camera 3. When the winch 100 continuously rotates forward, the body assembly 1 and the camera 3 continuously move upward, and the automatic inspection of the surface shape and safety condition of the steel wire rope 400 (which provides the basis for the safety performance evaluation of the steel wire rope 400) can be completed on the terminal information receiving device (for example, a mobile phone or a computer).

[0044] In an embodiment, three cameras 3 are provided, which are uniformly spaced on the edge of the first bellmouth structure 12 away from the first connecting pipe 11. Specifically, the three cameras 3 are at the same horizontal height, and the distance between adjacent cameras 3 is equal. By increasing the number of cameras 3 and setting the distance between the cameras 3 to be equal, the horizontal height of the cameras 3 is the same, and the up-down angle of the cameras 3 is adjusted. During the upward movement of the inspection and maintenance device, the three cameras 3 can automatically inspect the integrity of the steel wire rope 400 in 360 degrees without dead angle and transmit the inspection information in real time, thereby improving the reliability.

[0045] Optionally, the top of the first bellmouth structure 12 is provided with a bracket 31, and the camera 3 is installed on the bracket 31, so that the height and angle of the camera 3 can be adjusted through the bracket 31. The bracket 31 can refer to the prior art, and will not be described here.

[0046] The method for automatic maintenance using the steel wire rope inspection and maintenance device of the portal crane comprises the following steps: the winch 100 rotates in one direction (for example, forward), the body assembly 1 moves upward along the steel wire rope 400, and the lubricating grease 10 is applied to the steel wire rope 400. Specifically, when the winch 100 continuously rotates forward, the inspection and maintenance device 600 continuously moves upward, and the lubricating grease 10 in the first bellmouth structure 12 (container) at the upper end thereof uniformly applies to the outer peripheral surface of the steel wire rope 400 under the combined action of its own gravity, friction with the steel wire rope 400, and the restraining force of the inner wall of the first connecting pipe 11.

[0047] Optionally, the body assembly 1 can be moved to be submerged in the lubricating grease 10 at the fixed end 300, so that the maintenance of the top steel wire rope 400 is realized. After the fixed end 300 is completely submerged in the lubricating grease 10 for maintenance, the inspection and maintenance device 600 stops moving upward, and the inspection and maintenance of the entire steel wire rope 400 (difficult-to-inspect and maintain area 400A) are completed.

[0048] The method for automatically scraping oil by using the steel wire rope inspection and maintenance device of the portal crane comprises the following steps: the winch 100 is rotated in the other direction (such as the reverse direction), the body assembly 1 is moved downward along the steel wire rope 400, and the excess lubricating grease 10 on the steel wire rope 400 is scraped by the scraping assembly 2. Specifically, when the inspection and maintenance device 600 reaches the top end of the steel wire rope 400 and completes the inspection and maintenance of the fixed end 300, the winch 100 is reversed and lowered under the monitoring of the camera 3. At this time, the excess lubricating grease 10 remaining on the surface of the steel wire rope 400 is scraped downward by the scraping assembly 2, and moves downward synchronously with the inspection and maintenance device 600 until it returns to the ground level, and the inspection and maintenance of the whole steel wire rope 400 (difficult area 400A) are completed.

[0049] By arranging the body assembly 1, the camera 3 and the scraping assembly 2, the steel wire rope 400 passes through the body assembly 1, the first flared mouth structure 12 contains the lubricating grease 10, the body assembly 1 is fixed to the outer shell 510 of the movable pulley 500, and the inspection and maintenance device is moved by the forward and reverse rotation of the winch 100, so that the automatic inspection, maintenance and scraping treatment of the steel wire rope 400 are realized. The inspection and maintenance difficulty and cost of the steel wire rope 400 of the portal crane 700 are reduced, the inspection and maintenance quality and safety during the process are improved, the safety state of the steel wire rope 400 is ensured, and the service life of the steel wire rope 400 is prolonged.

[0050] The scraping assembly 2 comprises a second connecting pipe 22, a third flared mouth structure 23 and a fourth flared mouth structure 24 connected to two ends of the second connecting pipe 22. The inner diameter of the second connecting pipe 22 is greater than the outer diameter of the steel wire rope 400, the steel wire rope 400 can pass through the scraping assembly 2, the third flared mouth structure 23 faces upward during assembly, and the fourth flared mouth structure 24 faces downward. During scraping, the fourth flared mouth structure 24 and the second connecting pipe 22 scrape the excess lubricating grease 10 remaining on the surface of the steel wire rope 400 downward.

[0051] The body assembly 1 comprises two first split structures with a plane passing through the center line of the first connecting pipe 11 as a symmetrical surface, and the two first split structures are detachably connected. Further, the first flared mouth structure 12, the first connecting pipe 11 and the second flared mouth structure 13 are split structures, and all of them are two split structures symmetrically arranged along the symmetrical surface, that is, the first split structure is formed by splicing three split structures. Ear plates are arranged on the split structures, and the ear plates on the two split structures are connected by bolts 16 and nuts. The two split structures are buckled from both sides of the steel wire rope 400, facilitating disassembly and assembly. The first connecting pipe 11 is a plastic pipe, and the inner diameter thereof is 2mm-4mm greater than the outer diameter of the steel wire rope 400.

[0052] Similarly, the oil scraping assembly 2 comprises two second split structures symmetrically arranged along the symmetry plane, and the two second split structures are detachably connected. Further, the second connecting pipe 22, the third trumpet structure 23 and the fourth trumpet structure 24 are split structures, and the three are two split structures symmetrically arranged along the symmetry plane, that is, the second split structure is formed by splicing three split structures. The split structure is provided with an ear plate, and the ear plates on the two split structures are connected by bolts 16 and nuts. The two split structures are buckled from both sides of the steel wire rope 400, facilitating disassembly. The second connecting pipe 22 is a plastic pipe, and its inner diameter is 2mm-4mm larger than the outer diameter of the steel wire rope 400.

[0053] The oil scraping assembly 2 is connected to the inner side of the first trumpet structure 12, and the oil scraping assembly 2 scrapes the excess lubricating grease 10 on the steel wire rope 400 into the first trumpet structure 12, saving lubricating grease 10, protecting the environment, and reducing safety hazards.

[0054] The oil scraping assembly 2 is connected to the first trumpet structure 12 by the elastic rope 21. With the continuous rising of the inspection and maintenance device 600, when the top end of the oil scraping device contacts the fixed end 300, under the monitoring and guidance of the camera 3, the inspection and maintenance device 600 continues to move upwards, the elastic rope 21 is elastically deformed, and the oil scraping assembly 2 moves downwards relative to the body assembly 1, so that the fixed end 300 can be completely submerged in the lubricating grease 10. The oil scraping assembly 2 is connected to the first trumpet structure 12 by the elastic rope 21, which can prevent the oil scraping device from being fixed and causing interference with the fixed end 300, affecting the upward movement of the body assembly 1, and further affecting the submersion of the fixed end 300 in the lubricating grease 10.

Then, install the battery 6 on the magnet 4, and install the fixed support 5 such as a steel pipe. Then, buckle the first horn structure 12, the first connecting pipe 11 and the second horn structure 13 of the two half-symmetrical structures on the outer surface of the steel wire rope 400 to be inspected and maintained, connect and fix all the connecting lugs 15 by installing and tightening the connecting bolts 16, so that the body assembly 1 is buckled and connected as a whole on the outer surface of the steel wire rope 400, and the first connecting pipe 11 in the body assembly 1 is fixedly connected with the support 5.
