[0002] A hydraulic excavator usually includes a working device, an upper vehicle and an lower vehicle, and a slewing bearing is connected between the upper vehicle and the lower vehicle. The slewing bearing includes an outer ring, an inner ring, and a roller disposed between the inner ring and the outer ring. The outer ring is fixedly connected to the upper vehicle platform, the inner ring is fixedly connected to the lower vehicle support seat, the slewing motor and the reducer are fixed to the upper vehicle platform, and the output gear of the slewing motor meshes with the gear of the inner ring of the slewing bearing to drive the slewing bearing to rotate. In order to ensure good lubrication of the inner and outer rings of the slewing bearing, it is necessary to ensure that sufficient grease is stored in the middle of the raceways of the inner and outer rings. Since the grease will be consumed during the operation of the excavator, it is necessary to inject grease into the raceway on time to ensure the normal operation of the slewing bearing.

[0003] In order to facilitate the injection of grease, multiple through holes are usually set on the outer ring, and the multiple through holes are connected by pipe fittings. The filling port is set on the pipe fitting and placed in front of the excavator for easy filling operation. However, the filling port is usually protruding outward, and excavators and other operating machines usually work in mines with harsh working conditions. During the rotation operation, the stones are sharp and uneven after accumulation, and often collide with the filling port, causing these parts to be damaged and unable to work normally.

[0039] The embodiment of the utility model discloses a lubricating device, a slewing bearing and an operating machine, which are convenient for filling lubricating medium, improve filling efficiency, and the filling port is not easily damaged, thereby extending the service life of the lubricating device.

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] The lubrication device provided by the utility model is applicable to but not limited to filling lubricating medium into the slewing bearing, and can also provide lubricating medium for other equipment that needs lubrication. It is understandable that the lubricating medium includes but is not limited to grease, lubricating oil, etc., and butter can be used specifically. In the following embodiments, the example of injecting lubricating medium into the double-row ball slewing bearing is used as an example. The double-row ball slewing bearing is an important part of the slewing mechanism of an excavator and other working machinery. Please refer to Figure 1 , which includes a slewing bearing outer ring 210, a slewing bearing inner ring 220, an upper row of steel balls 230 and a lower row of steel balls 240, an upper sealing ring 250 and a lower sealing ring 260. The upper row of steel balls 230 and the lower row of steel balls 240 are arranged between the slewing bearing outer ring 210 and the slewing bearing inner ring 220. The upper sealing ring 250 and the lower sealing ring 260 are squeezed between the slewing bearing outer ring 210 and the slewing bearing inner ring 220, and are respectively located above the upper row of steel balls 230 and below the lower row of steel balls 240, so as to ensure that the lubricating medium in the steel ball roller will not overflow directly. During the operation, as the lubricating medium in the steel ball roller is consumed, the lubricating medium needs to be replenished. Therefore, a through hole connected to the steel ball roller is arranged on the slewing bearing outer ring 210 to inject the lubricating medium. The lubricating device provided by the utility model is used to add lubricating medium into the through hole, so that the operating machinery has better construction efficiency, not only improves the construction safety and reliability, but also has the ability of rapid installation and maintenance, and provides after-sales service guarantee for construction in harsh working conditions such as mines. In the following embodiments, the structure of the lubricating device is mainly described.

[0042] In some embodiments, see Figure 2-Figure 6The lubrication device provided by the utility model includes a centralized lubrication part 120, a fixing part and a plurality of lubrication pipes 110. Among them, the first end of each lubrication pipe 110 is used to connect with the interface of the lubricated equipment, and the second end is used to connect with the centralized lubrication part 120. It can be understood that the first end and the second end of the lubrication pipe 110 refer to the two opposite openings of the lubrication pipe 110. The centralized lubrication part 120 is provided with a sink 121 and channels 122 corresponding to each lubrication pipe 110. The filling port 123 of the channel 122 is provided on the sink 121 for filling the lubricating medium. The second end of each lubrication pipe 110 is respectively connected with the outlet 124 of the channel 122. The channels 122 corresponding to the lubrication pipes 110 may be connected or not connected. It can be understood that the centralized lubrication part 120 is provided with an outlet 124 corresponding to each lubrication pipe 110. When the channels 122 corresponding to at least two lubrication pipes 110 are connected, a filling port 123 corresponding to each connected channel 122 can be provided on the centralized lubrication part 120. When all channels 122 are not connected, a filling port 123 is provided for each channel 122. The filling port 123 is provided in the sink 121, that is, the filling port 123 is located in the concave part of the centralized lubricating part 120. Due to its low height, it is not easily impacted. The fixing part is provided on the centralized lubricating part 120 and / or the lubricating pipe 110, and is used to fix the lubricating device to the equipment to be lubricated.

[0043] The lubrication device provided by the utility model is installed on the equipment to be lubricated through the fixing parts, and the first end of each lubrication pipe 110 is connected to the interface of the equipment to be lubricated. When the lubricating medium is filled, the lubricating medium is injected from the filling port 123 on the centralized lubricating part 120, and the lubricating medium flows into each lubricating pipe 110 through the outlet 124 of the channel 122, and enters the corresponding interface through each lubricating pipe 110, so as to realize the filling of the equipment to be lubricated. In the present application, the filling port 123 is arranged on the centralized lubricating part 120, and the filling of each lubricating pipe 110 is realized through the centralized lubricating part 120, which is convenient for operation. In addition, by arranging a sink 121 on the centralized lubricating part 120, the filling port 123 is arranged in the sink 121, so as to form a protective effect on the filling port 123, which can effectively reduce the risk of the filling port 123 being directly damaged by foreign objects such as stones, and prolong the service life of the lubricating device. At the same time, the centralized lubrication of multiple lubrication points is convenient for the maintenance of after-sales personnel in the later stage.

[0044] In some embodiments, the filling port 123 is used to install a pressure injection oil cup, and the top of the pressure injection oil cup is located in the sink 121. The pressure injection oil cup is provided to facilitate the grease filling operation. In this embodiment, the top height of the pressure injection oil cup does not exceed the top surface of the centralized lubricating part 120, thereby preventing foreign objects such as stones from directly colliding with the pressure injection oil cup and causing damage to the pressure injection oil cup.

[0045] In some embodiments, see Figure 4-Figure 6, an independent channel 122 is provided corresponding to each lubrication pipe 110, and the second end of each lubrication pipe 110 is connected to the outlet 124 of the corresponding channel 122, and the filling port 123 of each channel 122 is provided on the sink 121. Although the lubrication pipes 110 of the lubrication device in this embodiment are centrally installed on the centralized lubrication part 120, they work independently of each other and can be injected with lubricating medium according to demand. Compared with providing lubricating medium to multiple channels 122 through the same filling port 123, each channel 122 is independently arranged, and the lubricating medium is separately filled through its own filling port 123, which is convenient for controlling the filling amount of lubricating medium in each channel 122, so that the filling of lubricating medium is more uniform. And all the filling ports 123 are concentrated on the same centralized lubrication part 120, which is convenient for filling operation. And if the lubrication pipe 110 is slightly collided, it is not seriously deformed or damaged, and the lubricating medium can continue to be filled. It can effectively improve the problem of uneven filling of lubricating medium, ensure the lubrication effect of the equipment to be lubricated, and increase the service life of the equipment to be lubricated.

[0046] In other embodiments, the channels 122 of at least two lubrication pipes 110 are connected, and a filling port 123 is provided on the centralized lubrication member 120 corresponding to each of the connected channels 122. The lubricating medium is uniformly filled into each of the connected channels 122 and the corresponding lubrication pipes 110 through the filling port 123. With the above arrangement, each channel 122 does not need to be filled separately, which is convenient for operation.

[0047] In some embodiments, at least two lubrication pipes 110 are respectively disposed on both sides of the centralized lubrication member 120. Figure 2 As shown, the left and right sides of the centralized lubricating part 120 are respectively provided with a first left lubricating pipe 1101, a second left lubricating pipe 1102, a first right lubricating pipe 1103, and a second right lubricating pipe 1104, so as to inject lubricating medium into the lubricated equipment from the left and right sides. This further improves the filling efficiency and the filling uniformity. In other embodiments, multiple lubricating pipes 110 may be provided on only one side of the centralized lubricating part 120 as needed, or a single lubricating pipe 110 may be provided on one side or both sides of the centralized lubricating part 120.

[0048] For further information, see Figure 3Each lubrication tube 110 includes a main body 111 and an inclined portion 112. Each main body 111 is arranged in parallel. One end of the inclined portion 112 is connected to the main body 111, and the other end is used to connect to the interface. The inclined portion 112 is inclined downward from the end connected to the main body 111 to the other end. It can be understood that the end of the inclined portion 112 away from the main body 111 is the second end of the lubrication tube 110. Through the setting of the inclined portion 112, the second end of the lubrication tube 110 can be connected to the interface in the middle of the equipment to be lubricated, and the main body 111 of the lubrication tube 110 can be located at the upper part of the equipment to be lubricated, so that even if multiple lubrication tubes 110 are set, the height of the lubrication tube 110 located at the bottom can be increased, further reducing the risk of the lubrication device being directly damaged by foreign objects such as stones, and extending the service life of the lubrication device.

[0049] In some embodiments, see Figure 4-Figure 6 The centralized lubricating part 120 is provided with a screw hole 125, and the fixing part includes a fastening screw matched with the screw hole 125. The centralized lubricating part 120 is connected to the equipment to be lubricated by the fastening screw, and the connection is reliable and easy to disassemble and assemble. In other embodiments, the centralized lubricating part 120 can also be connected to the equipment to be lubricated by other conventional methods such as welding.

[0050] In some embodiments, see Figure 7-Figure 8 The fixing part includes a tube clamp seat 130 that cooperates with the lubricating tube 110. The end face of the tube clamp seat 130 is provided with a limiting groove 131, and the tube clamp seat 130 is used to be fixedly connected to the equipment to be lubricated and limit the lubricating tube 110 to the limiting groove 131 and fit the equipment to be lubricated. By fixing the lubricating tube 110 with the tube clamp seat 130, the direction of the lubricating tube 110 can be limited, and a reasonable layout of the lubricating device can be achieved. In addition, when the tube clamp seat 130 is fixedly connected to the equipment to be lubricated, the equipment to be lubricated closes the notch of the limiting groove 131, on the one hand, the lubricating tube 110 is limited in the limiting groove 131 and cannot fall out, and on the other hand, the limiting groove 131 makes the lubricating tube 110 fit the equipment to be lubricated, such as fitting the outer wall of the equipment to be lubricated, so as to achieve fixed protection of the lubricating tube 110. In other embodiments, when the lubrication pipe 110 is shorter or has greater rigidity, a fixing member may be provided on the centralized lubrication member 120 and the centralized lubrication member 120 may be fixed to the equipment to be lubricated. Then, the lubrication pipe 110 is also fixed to the equipment to be lubricated accordingly due to its connection with the centralized lubrication member 120.

[0051] In some embodiments, lubrication pipes 110 are respectively provided on both sides of the centralized lubrication part 120, and at least one pipe clamp seat 130 is respectively provided on both sides of the centralized lubrication part 120, and the limiting grooves 131 on the pipe clamp seat 130 are provided one-to-one with the lubrication pipes 110 on the corresponding side. That is, the lubrication pipes 110 on the same side of the corresponding centralized lubrication part 120 are fixed to the lubricated equipment through at least one pipe clamp seat 130, and the pipe clamp seat 130 fixes each lubrication pipe 110 on the corresponding side at the same time, which simplifies the structure and facilitates assembly. In other embodiments, a separate pipe clamp seat 130 can also be provided for each lubrication pipe 110 to fix it.

[0052] In some embodiments, the fixing member is used for detachable connection with the equipment to be lubricated. The detachable connection is adopted, and disassembly and assembly are convenient. Specifically, the fixing member is bolted to the equipment to be lubricated. In the case where the fixing member includes a pipe clamp seat 130, a bolt hole 132 can be specifically provided on the pipe clamp seat 130. During assembly, the pipe clamp seat 130 is connected to the equipment to be lubricated by fixing bolts and washers and fixes the lubrication pipe 110. At the same time, the second end of the lubrication pipe 110 is centrally installed on the centralized lubrication member 120. It is only necessary to install the centralized lubrication member 120 on the equipment to be lubricated by tightening screws, etc., which greatly reduces the workload of installing and disassembling the centralized lubrication device and facilitates the disassembly and maintenance of the centralized lubrication device in the later stage.

[0053] The following is an explanation with a specific embodiment. In this embodiment, the lubrication device includes a first left lubrication pipe 1101, a second left lubrication pipe 1102, a first right lubrication pipe 1103 and a second right lubrication pipe 1104.

The first right lubrication pipe 1103 and the second right lubrication pipe 1104 are also fixedly connected to the outer ring of the slewing bearing by using fixing bolts, washers and a pipe clamp seat 130. The directions of the first right lubrication pipe 1103 and the second right lubrication pipe 1104 are optimized and fixedly protected so that they are close to the outer wall of the slewing bearing. The first ends of the first left lubrication pipe 1101, the second left lubrication pipe 1102, the first right lubrication pipe 1103 and the second right lubrication pipe 1104 are connected to the interface of the slewing bearing through the first joint 113 and the oil pipe snap nut, and the second ends of the first left lubrication pipe 1101, the second left lubrication pipe 1102, the first right lubrication pipe 1103 and the second right lubrication pipe 1104 are connected to the centralized lubrication member 120 through the second joint 114. The centralized lubrication member 120 is installed on the upper part of the slewing bearing outer ring 210 by fastening screws, and a sinking platform 121 is provided on the centralized lubrication member 120, and the centralized lubrication member 120 and each lubrication pipe 110 are respectively provided with independent channels 122, and the filling port 123 of each channel 122 is provided with a sinking platform 121, and the filling port 123 is connected to a pressure injection oil cup, and the pressure injection oil cup is completely sunk in the sinking platform 121 of the centralized lubrication member 120. The above arrangement can prevent stones and foreign objects from directly damaging the injection oil cup, and at the same time, multiple lubrication points can be lubricated centrally to facilitate subsequent maintenance by after-sales personnel.

Specifically, the slewing bearing 1 includes the lubricating device 10 and the double-row ball slewing bearing body 20.

[0055] In some embodiments, the centralized lubrication member 120 is disposed on the upper portion of the slewing bearing 1. This reduces the risk of the lubrication device being directly damaged by foreign objects such as stones, and prolongs the service life of the lubrication device.

[0056] The utility model also provides an operating machine, see Fig. 9The operating machine includes any one of the lubricating devices or slewing bearings 1 in the above embodiments.
