Description

Technical Field

[0001] The utility model belongs to the technical field of crane lubrication, and particularly relates to an automatic lubrication gear for a crane rotary gear ring. Background Art

[0002] A gantry crane is a kind of lifting machinery. Its main feature is that the main part of the lifting machinery is installed on a gantry structure, and the lifting and moving of goods are achieved through the movement of the gantry structure. A gantry crane is usually composed of a gantry structure, a lifting machinery, a lifting machinery control system and an electrical system. A gantry crane, referred to as a gantry crane, is equipped with a slewing gear. The slewing gear is a mechanism with an inner shaft and outer teeth. The upper part of the gantry crane is meshed with a planetary gear and a slewing gear ring, and the two rotate continuously to adjust the direction of the gantry crane boom. Because the planetary gear and the slewing gear ring need to be in constant contact, they need to be lubricated. The traditional way of lubricating is to rely on manpower and manual oiling. With the rapid development of automatic lubrication in the field of gantry cranes, lubrication systems that are automatically controlled by electronic systems have appeared in China, getting rid of manpower and automatic lubrication. However, there are still many problems with the lubrication of rotary gears today: before the automatic lubrication device was available, oiling could only be done manually, which was time-consuming, labor-intensive, and dangerous. Employees had to climb up and down repeatedly to oil the gear rings, affecting production efficiency. Port machinery is a special industry. At present, some manufacturers have studied automatic lubrication systems and have produced specific products, which can realize the process of oiling through computer-controlled solenoid valves. However, such systems are often very expensive due to the scarcity of competitors in special industries. After actual comparison by professionals, it was found that the reliability of such electronic equipment would become a huge problem in harsh environments such as docks. The electric control valve oiling equipment often has oil blockage. At the same time, the manufacturer can only be sought to repair the related equipment, and it is inconvenient to solve it by oneself.

[0003] The publication number is "CN213017638U", which is an automatic lubrication device for a slewing gear ring of a crane. The device includes an oil storage tank and a machine room shell. The top of the oil storage tank is provided with a refueling port. The bottom of the oil storage tank is provided with a bottom plate, which is an inclined surface. The bottom side of the bottom plate is fixedly provided with an oil delivery trough, which is connected with the oil storage tank. The bottom of the machine room shell is fixedly provided with a first angle iron and a second angle iron. The utility model uses and applies an oil delivery trough, which automatically lubricates by gravity, is stable and reliable, does not have the risk of leakage and software system failure, saves manpower, avoids the danger in the oiling process, relies on gravity oiling, makes the lubricating oil spread evenly, and has a good lubrication effect. The first angle iron and the second angle iron are applied, which does not affect the existing equipment, does not need to disassemble the existing device, and only needs to directly add the corresponding structure.

[0004] Although the above-mentioned device can assist in automatic lubrication during use, during the lubrication process, when the lubricating oil is applied to the outer surface of the rotating gear ring body, it cannot be applied evenly, and the overall application efficiency is low. During the application period, it is very easy for the outer surface of the rotating gear ring to have dead corners that are not applied with lubricating oil. The overall application efficiency is low, so it needs to be improved. Utility Model Content

Slots 75 are provided on both sides of the front end of the slide bar 71, and the inner side of the block 624 is inserted into the inner side of the slot 75. By setting the lubricating mechanism 7, the device can be used during use through the mutual meshing transmission of the lubricating gear body 74 and the rotating gear body.

[0033] Principle and advantages of use: By setting the mounting mechanism 6, the device can be used to slide the slide bar 71 into the inner side of the guide rail 621 during use. At this time, by pulling the pull ring 626, the guide rail 621 and the connecting shaft 625 pull the block 624 to shrink. After the block 624 shrinks, the slide bar 71 can be completely slid into the inner side of the guide rail 621. When the block 624 contacts the slot 75, the limit spring 623 resets the block 624 to be inserted into the inner side of the slot 75, so that the lubricating gear body 74 on the outer surface of the oiling steel pipe 73 can contact the rotating gear body and mesh with it.

At this time, the lubricating oil can be transported to the oiling steel pipe 73 through the connecting pipe 72, and the lubricating oil is transmitted to the top of the lubricating gear body 74 through the oiling steel pipe 73. When the lubricating gear body 74 rotates, the inclined scraper 66 at the bottom of the vertical rod 65 can assist in scraping the lubricating oil, so that the lubricating oil can slide onto the rotating gear body more evenly. At this time, the lubricating oil can be used in combination with the lubricating gear body 74. The meshing transmission of the gear body 74 allows the lubricating oil to be more evenly applied to the outer surface of the rotating gear ring body 3, achieving a better lubrication effect. When disassembly is required, the connecting shaft 625 can be moved outward by adjusting the pull ring 626, and the block 624 can be moved outward by the connecting shaft 625. Then, the connection between the connecting pipe 72 and the oil pump is released, and the slide bar 71 can be pulled out, so that the device can quickly replace the lubricating gear body 74 for inspection and cleaning, making the device as a whole more convenient to use, more practical, and worthy of popularization.
