Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a driven steel wire rope oil cleaning, maintenance and waste oil recovery device for cranes. Background Technology

[0002] With the rapid development of port logistics, gantry cranes, as core equipment for cargo loading and unloading in ports, directly impact the operational level of ports in terms of safety and efficiency. The crane's wire rope, as a key transmission component, endures high loads and complex working conditions for extended periods. During actual use, wire ropes are prone to oil accumulation, leading to safety accidents such as pulley wear and rope breakage. The grease residue on the wire rope, mixed with dust, forms sludge that exacerbates corrosion and shortens its service life. Furthermore, manual cleaning of oil and lubricating grease from the wire rope increases maintenance costs. Utility Model Content

[0008] As a further improvement to the above technical solution, the drive end of the brush drive component is provided with a sleeve, the pressure sensor is located inside the sleeve, and a connecting rod is provided on the outside of the brush holder. The connecting rod is inserted into the sleeve and abuts against the pressure sensor.

[0009] As a further improvement to the above technical solution, the brush drive and pressure sensor are electrically connected to the controller, which is mounted on the housing. The controller is a PLC controller, and the brush drive is an electric push rod.

[0010] As a further improvement to the above technical solution, the maintenance module includes a cylindrical maintenance box and an oiling tube located in the center of the maintenance box. Both the upper and lower ends of the oiling tube are open and connected to corresponding upper through holes and through holes, respectively. Both the upper and lower ends of the oiling tube penetrate the maintenance box. A storage cavity for storing grease is formed between the inner wall of the maintenance box and the outer wall of the oiling tube. A grease outlet connected to the inner cavity of the oiling tube is provided at the lower end of the storage cavity, and an extrusion mechanism is provided at the upper end of the storage cavity.

[0011] As a further improvement to the above technical solution, the extrusion mechanism includes an electric telescopic rod and a piston connected to the electric telescopic rod.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 4As shown, a preferred embodiment of this utility model provides a driven steel wire rope oil stain cleaning, maintenance, and waste oil recovery device for cranes, including a housing 10, an oil stain cleaning module 20, a maintenance module 30, and a waste oil recovery module 40 disposed on the housing 10. In this embodiment, the oil stain cleaning module 20 is located directly below the maintenance module 30.

[0026] The casing 10 is a hollow shell structure assembled from a top plate 11, a bottom plate 12, and multiple side plates 13. The oil stain cleaning module 20 and the maintenance module 30 are located inside the casing 10. The inner side of the casing 10 is provided with a horizontal partition 14 and a vertical partition 15. The vertical partition 15 is fixedly installed between the top plate 11 and the bottom plate 12, and the horizontal partition 14 is fixedly installed between the side plates 13 and the vertical partition 15. The top plate 11, bottom plate 12, horizontal partition 14, side plates 13, and vertical partition 15 are rectangular steel plates. The bottom plate 12, horizontal partition 14, side plates 13, and vertical partition 15 form a first cavity, in which the oil stain cleaning module 20 is located. The top plate 11, horizontal partition 14, side plates 13, and vertical partition 15 form a second cavity, in which the maintenance module 30 is located.

[0027] The top plate 11 has multiple upper through holes 111 that correspond one-to-one with and are adapted to the wire ropes 55 of the lifting equipment; the transverse partition 14 has multiple through holes 141 that correspond one-to-one with the upper through holes 111 and are adapted to the wire ropes 55; and the bottom plate 12 has multiple lower through holes 121 that correspond one-to-one with the through holes 141 and are adapted to the wire ropes 55. Figure 4 As shown, the lifting equipment includes a crossbeam 51, support arms 52 disposed at both ends of the crossbeam 51, and a trolley 53 disposed above the crossbeam 51. The housing 10 is disposed below the crossbeam 51 and is fixedly connected to the trolley 53 by a fixing rod 54. Multiple steel wire ropes 55 of the lifting equipment pass through the housing 10 through multiple corresponding upper through holes 111, through holes 141, and lower through holes 121. The upper through holes 111, through holes 141, and lower through holes 121 limit the movement of the steel wire ropes 55, ensuring that the steel wire ropes 55 remain vertical when passing through the oil cleaning module 20 and the maintenance module 30, thus facilitating the oil cleaning module 20 to scrape and clean the oil and the maintenance module 30 to apply grease.

[0028] Furthermore, in order to prevent the wire rope 55 from causing wear on the upper through hole 111, through hole 141 and lower through hole 121, a protective tube 16 is threaded into the upper through hole 111, through hole 141 and lower through hole 121, and the inner diameter of the protective tube 16 is adapted to the diameter of the wire rope 55.

[0029] The oil stain cleaning module 20 is used to scrape and clean the oil stains on the surface of the wire rope 55. It includes a cleaning mechanism 21 and a dynamic adjustment mechanism 22. The cleaning mechanism 21 includes two brush holders 211 and cleaning brushes 212 set on each brush holder 211. The two brush holders 211 are opposite to each other and arranged around the wire rope 55. The wire rope 55 is sandwiched between the two brush holders 211. The inner surface of each brush holder 211 is semi-circular and forms the cleaning brush 212. The oil stain cleaning module 20 uses the contact friction between the cleaning brush 212 and the wire rope 55 to achieve the driven movement of the cleaning brush 212 through the movement of the wire rope 55, thereby achieving the purpose of cleaning the oil stains on the wire rope 55. In addition, during the winding and rising process of the wire rope 55, the cleaning brush 212 can scrape and clean the grease squeezed out from the wire rope 55 under tension and the dirt on the surface of the wire rope 55, effectively avoiding the generation of oil stains when the wire rope 55 is wound up. Preferably, the bristles of the cleaning brush 212 are made of PA material, which has good heat resistance, wear resistance and chemical corrosion resistance.

[0030] The dynamic adjustment mechanism 22 is used to adaptively adjust the cleaning brush 212, avoiding scratching the surface of the wire rope 55 while the cleaning brush 212 scrapes away oil stains. The dynamic adjustment mechanism 22 includes two brush drive units 221 and two pressure sensors 222. Each brush drive unit 221 is connected to one of the brush holders 211. A pressure sensor 222 is provided between each brush drive unit 221 and the corresponding brush holder 211. The pressure sensor 222 is used to detect the cleaning force of the cleaning brush 212. The brush drive units 221 and the pressure sensors 222 are electrically connected to the controller 223, which is mounted on the housing 10. Specifically, one end of the brush drive component 221 is fixed to the inner wall of the housing 10, and the other end is the drive end. The drive end of the brush drive component 221 is provided with a sleeve 224, and a pressure sensor 222 is located inside the sleeve 224. A connecting rod 213 is provided on the outside of the brush holder 211, and the connecting rod 213 is inserted into the sleeve 224 and abuts against the pressure sensor 222. A displacement sensor can be provided on the brush drive component 221 to detect the displacement of the drive end of the brush drive component 221, thereby measuring the displacement of the cleaning brush 212. The displacement sensor is electrically connected to the controller 223. In this embodiment, the controller 223 is a PLC controller, and the brush drive component 221 is an electric push rod. The two cleaning brushes 212 of the cleaning mechanism 21 approach the wire rope 55 under the pushing force of the brush drive 221 and press against the wire rope 55 with a certain pressure. The pressure sensor 222 detects the reaction force exerted by the wire rope 55 on the cleaning brushes 212 and sends the detected force value to the controller 223. The controller 223 compares the detected force value with the set force value and controls the brush drive 221 accordingly to drive the cleaning brushes 212 to move closer to or away from the wire rope 55, thereby adjusting the force exerted by the cleaning brushes 212 on the wire rope 55. While the cleaning brushes 212 scrape off the oil stains on the surface of the wire rope 55, the surface of the wire rope 55 is not scratched.

[0031] The maintenance module 30 is arranged around the wire rope 55 and is used to apply grease to the wire rope 55. The maintenance module 30 includes a cylindrical maintenance box 31 and an oiling pipe 32 located in the center of the maintenance box 31. The upper and lower ends of the oiling pipe 32 are open and connected to the corresponding upper through hole 111 and through hole 141, respectively. The upper and lower ends of the oiling pipe 32 penetrate the maintenance box 31. A storage cavity 33 for storing grease is formed between the inner wall of the maintenance box 31 and the outer wall of the oiling pipe 32. The lower end of the storage cavity 33 is provided with a grease outlet 34 that communicates with the inner cavity of the oiling pipe 32. The upper end of the storage cavity 33 is provided with an extrusion mechanism 35, which is used to extrude the grease in the storage cavity 33 through the grease outlet 34 into the inner cavity of the oiling pipe 32.

[0032] Specifically, the extrusion mechanism 35 includes an electric telescopic rod 351 and a piston 352 connected to the electric telescopic rod 351. The electric telescopic rod 351 is disposed on the inner wall of the upper end of the curing box 31 and is used to press down the piston 352. The piston 352 is interference-fitted with the inner wall of the storage cavity 33. The electric telescopic rod 351 is electrically connected to the controller 223.

[0033] Preferably, the upper end of the inner cavity of the oiling tube 32 is set as a tapered cavity that gradually narrows radially upwards. The inner diameter of the open end of the tapered cavity is the same as the inner diameter of the protective tube 16. The tapered cavity can not only scrape off the excess grease adhering to the surface of the wire rope 55, but also make the grease application more uniform. The scraped-off grease will be repeatedly applied as the wire rope 55 is wound up, thus avoiding the waste of grease application on the wire rope 55.

[0034] The waste oil recovery module 40 is used to recover the oil and grease scraped off the wire rope 55, thus preventing pollution of the surrounding environment. The waste oil recovery module 40 includes a recovery box 41 and a suction pump 42. The recovery box 41 is fixed to the outer wall of the housing 10 with screws. The suction pump 42 is installed on the recovery box 41. The oil outlet of the suction pump 42 is connected to the recovery box 41 through a pipe. The oil inlet of the suction pump 42 is connected to the recovery pipe 43. The recovery pipe 43 extends into the first cavity of the housing 10. The suction pump 42 is electrically connected to the controller 223.

[0035] like Figure 4 As shown, in use, during the winding process of the wire rope 55, the wire rope 55 enters the housing 10 and passes through the oil cleaning module 20 and the maintenance module 30 in sequence. As the wire rope 55 winds up, the cleaning brush 212 removes oil and grease from the surface of the wire rope 55. The controller 223 controls the suction pump 42 to draw the oil and grease scraped from the wire rope 55 into the recycling box 41 for recovery. The pressure sensor 222 detects the cleaning force of the cleaning brush 212 to control the brush drive 221 to move the cleaning brush 212 closer to or further away from the wire rope 55, thereby adjusting the force exerted by the cleaning brush 212 on the wire rope 55. This ensures that the cleaning brush 212 removes oil from the surface of the wire rope 55 while avoiding scratching the surface of the wire rope 55. After the cleaning brush 212 removes the oil and grease from the surface of the wire rope 55, the operator sends a control command to the electric telescopic rod 351 from the operating platform of the lifting equipment. The electric telescopic rod 351 pushes the piston 352 downward, and the grease in the storage chamber 33 is squeezed out from the grease outlet 34 into the inner cavity of the oiling pipe 32 under pressure. As the wire rope 55 is wound up, the grease adheres to the surface of the wire rope 55, completing the grease application.

[0036] This invention, by incorporating an oil stain cleaning module 20 and a maintenance module 30, enables the removal and cleaning of grease squeezed out from the wire rope 55 under tension, as well as oil, dust, impurities, and dirt on the surface of the wire rope 55 during the winding operation of the lifting equipment. It also allows for the application of grease to the surface of the wire rope 55. A dynamic adjustment mechanism 22 prevents scratching the surface of the wire rope 55 while the cleaning brush 212 removes oil stains. A waste oil recovery module 40 recovers the oil stains and grease scraped from the wire rope 55, thus achieving an automated closed-loop system for oil stain cleaning, maintenance, and waste oil recovery of the wire rope 55. This effectively prevents the accumulation of oil stains and lubricating grease on the surface of the wire rope 55, significantly reducing the risk of equipment failure and personal injury caused by wire rope breakage, extending the service life of the wire rope 55, and lowering manual maintenance costs.

[0037] Any descriptions not covered in the above specific embodiments of this utility model belong to the well-known technology in the field, and can be implemented by referring to the well-known technology.

[0038] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
