Description

Technical Field

[0001] The invention relates to the field of port crane auxiliary equipment, in particular to a windproof cable safety protection device for a port logistics crane. Background Art

[0002] In order to adapt to the development trend of large-scale cargo ships and improve their loading and unloading efficiency, port cranes are also constantly developing in the direction of large-scale. The large-scale cranes also increase their center of gravity, increase their windward area, and increase the possibility of being hit by wind disasters. In recent years, large port cranes have been hit by wind disasters due to typhoons or hurricanes. Once an accident occurs, it not only directly affects the production order of the dock, but also causes related companies to suffer significant economic losses and even casualties. At present, the typhoon and hurricane protection devices of large port cranes mainly include track clamps, anchors (hooks), wheel stoppers, windproof wheel pins, windproof pull rods or cables, etc. Among these wind protection methods, windproof pull rods or cables are one of the most powerful and critical devices for typhoon and hurricane protection.

[0003] However, the steel wire rope used in the existing windproof cable is too long, so the probability of defects is higher. A part with poor tension is very likely to break during use, but it cannot be discovered in time, which poses a great safety risk. In addition, the steel wire rope is in contact with the sea breeze during use, which makes it very easy to be eroded and corroded by the sea breeze, reducing its service life. Currently, most of the staff wipe the surface of the steel wire rope with a brush to replenish oil for maintenance, but this method has high labor intensity and poor lubrication effect. In addition, a large amount of oil is likely to drip onto the surrounding ground during wiping, causing a lot of waste. Summary of the invention

[0038] In a specific embodiment of the present invention, when the sea breeze blows on the blade 301, the rotating ring 302 rotates along the side wall of the fixed ring 303, thereby rotating the rack 304, driving the fourth gear 305 and the rotating rod 306 to rotate, and then driving the rotating block 312 and the transmission shaft 401 to rotate, using natural wind energy to provide power for movement, which is more energy-saving and environmentally friendly.

[0039] The rotation of the transmission shaft 401 drives the rotation of the second gear 404 and the third gear 412, which in turn drives the two detection rollers 409 to roll synchronously along the side wall of the wire rope 101, and then drives the installation cover 2 to move along the side wall of the wire rope 101. When rust and impurities appear on the surface of the wire rope 101, the two detection rollers 409 abut against the wire rope 101, causing the sliding rod 406 to contract. When the surface of the wire rope 101 is broken, the two detection rollers 409 are clamped with the wire rope 101 and no longer move, thereby observing whether the installation cover 2 is The broken part of the wire rope 101 can be found during movement, making the detection more convenient and reliable, and ensuring the safe use of the wire rope 101; at the same time, when the two detection rollers 409 encounter the broken wire rope 101 and are stuck, the wedge block 311 can slide on the side wall of the rotating block 312, and the second spring 309 contracts, so that the blade 301 can continue to rotate, avoiding damage to the blade 301 caused by the sea breeze. At the same time, by observing the movement state of the blade 301 and the mounting cover 2, it is more reliable to judge whether the wire rope 101 is broken.

[0040] During the movement of the entire equipment, when the moving rod 601 is in contact with the supporting block 102 below, the special-shaped plate 602 moves upward. At this time, the sleeve rod 606 located above contacts the side wall of the limit block 607. Due to the action of the sliding surface 605 and the limit surface 604, the detection roller 409 can only rotate in one direction, so that the installation cover 2 slides upward along the wire rope 101. When the moving rod 601 is in contact with the supporting block 102 above, the special-shaped plate 602 moves downward. At this time, the sleeve rod 606 located below contacts the side wall of the limit block 607. Due to the action of the sliding surface 605 and the limit surface 604, the detection roller 409 can only rotate in the opposite direction, so that the installation cover 2 slides downward along the wire rope 101, so that the detection roller 409 reciprocates up and down on the side wall of the wire rope 101 for detection, and the detection is more convenient and reliable.

[0041] When the mounting cover 2 moves back and forth on the side wall of the steel wire rope 101, when the moving rod 601 touches the supporting block 102, the special-shaped plate 602 moves up and down along the side wall of the mounting cover 2, thereby driving the sealing plate 506 to slide along the side wall of the slide groove 504. During the sliding process of the slide groove 504, the through hole 507 is aligned with the oil outlet hole, so that the lubricating oil in the oil storage tank 501 flows into the oil groove 509 along the oil outlet pipe 505, and the lubricating oil is applied to the surface of the steel wire rope 101 through the bristles 510, thereby realizing automatic application of lubricating oil to the surface of the steel wire rope 101, which is more convenient and the application is more uniform, thus avoiding waste caused by dripping of lubricating oil.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
