Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a slewing bearing platform for a large-scale marine floating crane system. Background Art

[0002] The slewing bearing platform is a mechanical device that can achieve relative rotational motion. It has a wide range of applications. For example, in the field of construction machinery, the slewing bearing platform is one of the key components. It enables the crane's lifting arm to rotate freely in the horizontal direction, thereby enabling lifting operations at different angles and expanding the crane's working range.

[0003] Existing automatic lubrication devices usually use independent oil storage tanks, which take up a large space and have limited installation locations. In addition, they mostly use pressure oil supply or injection oil supply, which is prone to problems such as uneven oil supply.

[0004] For this purpose, we propose a slewing bearing platform for large-scale marine floating crane systems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides a slewing bearing platform for a large-scale marine floating crane system, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a slewing bearing platform for a large-scale marine floating crane system, comprising a support seat, a rotating assembly is provided on the upper surface of the support seat, the rotating assembly comprises an outer gear ring, the outer gear ring is provided on the upper surface of the support seat, the outer gear ring is rotatably connected to the support seat, the inner wall of the outer gear ring is provided with an inner gear ring, the inner wall of the outer gear ring and the outer wall of the inner gear ring are rotatably connected, the inner gear ring is fixedly connected to the upper surface of the support seat, a plurality of rolling bodies are connected to the inside of the inner gear ring, the inner wall of the inner gear ring is provided with gear teeth, the outer wall of the gear teeth is provided with a motor, the gear The outer wall of the tooth is meshed with the output end of the motor. The outer wall of the inner gear ring is provided with a lubrication assembly, which includes an oil storage ring, which is fixedly connected to the inner wall of the inner gear ring. The lower surface of the oil storage ring contacts the upper surface of the gear teeth. A partition plate is provided inside the oil storage ring. The oil storage ring and the partition plate are fixedly connected. The partition plate divides the interior of the oil storage ring into chamber one and chamber two. The outer walls of chamber one and chamber two are both provided with capillary holes, and the number of the capillary holes is several. The inner wall of the oil storage ring is connected to an oil nozzle, and the inner and outer walls of the oil storage ring are both connected to a pump body. The interior of the partition plate is provided with an oil inlet assembly:

[0007] The motor is the power source of the device. The motor is installed on the floating device and rotates along the inner gear ring. The floating device is connected to the outer gear ring. When the outer gear ring rotates, the floating device rotates together and injects the lubricating oil into the oil storage ring through the oil nozzle. The oil storage ring is divided into two independent chambers by a partition plate. The outer walls of the two chambers are provided with capillaries. The lubricating oil in chamber one slowly flows into the inner ring teeth through the capillaries. At this time, the inner ring teeth are meshed with the output end of the motor for lubrication. The lubricating oil in chamber two flows into the rolling body in the inner gear ring through the capillaries, lubricating the rolling body and reducing the friction between the rolling body and the outer gear ring. Due to the large changes in temperature and pressure in the marine environment, relying solely on the capillary action may not be able to meet the lubrication needs. Therefore, a pump body is installed on the inner and outer walls of the oil storage ring. The pump body applies pressure to the inside of the oil storage ring so that the lubricating oil can be stably delivered to the lubrication point.

[0008] As a preferred technical solution of the present invention, the oil inlet assembly includes a circular hole, which is opened on the outer wall of the partition plate, and a solenoid valve is installed inside the circular hole.

[0009] By installing a solenoid valve in the partition plate, when the lubricating oil capacity in the two chambers is uneven, the solenoid valve is opened and the lubricating oil in the chamber with more oil flows into the chamber with less oil, so that the lubricating oil capacity remains uniform, avoiding the situation where the lubricating oil is easily unevenly distributed in the oil storage ring when the slewing bearing platform is in different working states, such as tilting, rotating or shaking due to the impact of waves.

[0010] The beneficial effects of the utility model are as follows: by directly installing the oil storage ring on the inner ring, the space of the inner ring is fully utilized without taking up additional space, making the entire system more compact; the annular structure of the oil storage ring can better adapt to the shape of the slewing support platform, ensuring uniform distribution of lubricating oil in all directions, and improving the lubrication effect.

[0011] The utility model balances the oil level by providing a partition plate and a solenoid valve, ensuring that the lubricating oil in the two chambers remains relatively balanced regardless of the platform's posture. Thus, at all times, the capillary channel or lubrication distribution system can draw lubricating oil from a relatively stable oil level, thereby ensuring a continuous and stable supply of lubricating oil to each lubrication point of the slewing bearing.

A partition plate 302 is provided inside the oil storage ring 301, and the oil storage ring 301 and the partition plate 302 are fixedly connected. The partition plate 302 divides the interior of the oil storage ring 301 into chamber one and chamber two. The outer walls of chamber one and chamber two are both provided with capillary holes 304, and the number of capillary holes 304 is several. The inner wall of the oil storage ring 301 is connected to the oil nozzle 303, and the inner and outer walls of the oil storage ring 301 are both connected to the pump body 305. The interior of the partition plate 302 is provided with a balancing oil quantity component 4.

[0022] The motor 5 is the power source of the device. The motor 5 is installed on the floating device and rotates along the inner gear ring 202. The floating device is connected to the outer gear ring 201. When the outer gear ring 201 rotates, the floating device rotates together, injecting lubricating oil into the oil storage ring 301 through the oil nozzle 303. The oil storage ring 301 is divided into two independent chambers by the partition plate 302. The outer walls of the two chambers are provided with capillary holes 304.
