Description

Technical Field

[0001] The utility model relates to the technical field of engineering equipment, in particular to a lubricating device for a belt roller bearing. Background Art

[0002] At present, the lubrication method of commercial concrete belt roller bearings is mainly carried out by manual oiling at regular intervals. Commercial concrete belt roller is an indispensable part of concrete mixing station, mainly used for conveying raw materials such as sand, stone, cement, etc. Its normal operation directly affects the efficiency and stability of the entire production line.

[0003] However, when the belt roller bearing is in use, the friction between the internal structures of the bearing will generate heat and a certain amount of wear between the friction, so it is necessary to add grease to the bearing of the belt roller to reduce the friction and wear of the internal structure of the bearing, and provide the necessary cooling effect to prevent the bearing from overheating and lubricating oil deterioration. However, depending on the usage scenario, some belt roller bearings are in a higher position. Every time the bearing is filled with grease, the operator needs to climb up to work, which poses a safety hazard. In addition, when the bearings on both sides of the belt roller need to be refilled with oil, it is necessary to bypass the belt to complete the refilling operation, which is laborious and time-consuming.

[0004] Based on the above situation, it is necessary to design a lubrication device for a belt roller bearing to solve the above problems. Utility Model Content

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0022] Referring to Figures 1 - 5 As shown, a lubrication device for a belt roller bearing includes a bracket 1. The two sides of the bracket 1 are connected with a bearing body 2. The bearing body 2 is a structure of the prior art and will not be elaborated. A roller body 3 is connected to the two bearing bodies 2. When the roller body 3 operates, the roller body 3 rotates on the bearing body 2. An oil tank 4 is connected to the bearing body 2. The output end of the oil tank 4 adds grease to the inside of the bearing body 2 through a connecting piece 7, and the oil tank 4 is located above the connecting piece 7. The bearing body 2 consumes its own grease during use to reduce friction and heat conduction. The inside of the oil tank 4 contains a certain volume of grease. As the bearing body 2 consumes the grease inside it, the grease inside the oil tank 4 will gradually flow into the inside of the bearing body 2 under the action of gravity, so that the inside of the main body is always filled with grease to achieve the lubrication effect. A pump body 5 is connected to the bracket 1. The output end of the pump body 5 is connected to a distributor 6 with a plurality of output ends. The output ends of the distributor 6 are respectively connected to the oil tanks 4 on both sides of the roller body 3. A control component for regulating the delivery of grease is provided on both the oil tank 4 and the pump body 5.

[0023] During use, the grease in the oil tank 4 will be gradually consumed as the bearing body 2 is used. At this time, through the control component, the pump body 5 is controlled to introduce external grease into the oil tank 4. During the introduction process, when passing through the dispenser 6, the dispenser 6 can introduce a certain volume of grease into the oil tank 4, so that the oil tank 4 is refilled with grease. During this process, there is no need for workers to constantly observe the consumption of grease inside the bearing body 2, avoiding the time-consuming and laborious addition of grease to the bearing body 2 by workers, and further avoiding potential safety hazards caused by workers climbing to high places for operations.

[0024] Among them, the control component includes a controller 8 and a liquid level sensor 9. The liquid level sensor 9 is connected to the oil tank 4. The output end of the liquid level sensor 9 is connected to the input end of the controller 8, and the output end of the controller 8 is connected to the pump body 5. The liquid level sensor 9 is used to sense the liquid level height of the grease inside the oil tank 4 and form a liquid level electrical signal. The controller 8 receives the liquid level electrical signal output by the liquid level sensor 9 and outputs a control signal, and the control signal controls the operation of the pump body 5. Then, in cooperation with the dispenser 6, the pump body 5 can add different volumes of grease to different oil tanks 4 at the same time, and the volume of grease inside the oil tank 4 is determined by the threshold preset by the liquid level sensor 9.

[0025] The above-mentioned dispenser 6 is a prior art structure and will not be elaborated. Its main function is to measure and distribute grease in the lubrication system to ensure that each lubrication point can receive an appropriate amount of grease. There is an electrical device (not shown in the drawing) inside the dispenser 6 to control the output of the dispenser 6. In the present utility model, the dispenser 6 is electrically connected to the controller 8, and the controller 8 controls the operation of the dispenser 6. Then, in cooperation with the pump body 5, the volume of grease output by different output ends of the dispenser 6 each time is controlled.

[0026] Refer to Figures 4 - 5 As shown, further, the connecting piece 7 is connected and installed on one side of the bearing body 2. The connecting piece 7 is hermetically connected to the bearing body 2. An oil delivery cavity 10 is formed on the connecting piece 7. The output end of the oil delivery cavity 10 is communicated with the inside of the bearing body 2, and the input end of the oil delivery cavity 10 is communicated with the output end of the oil tank 4. The grease that has settled inside the oil tank 4 is introduced into the bearing body 2 through the oil delivery cavity 10 and is used for lubricating the bearing rotor inside the bearing body 2.

[0027] Among them, in order to ensure that the grease can be accurately introduced to the appropriate position inside the bearing body 2, several introduction channels 11 communicating with the oil delivery cavity 10 are further formed on the connecting piece 7. The oil delivery cavity 10 is communicated with the inside of the bearing body 2 through the introduction channels 11. The introduction channels 11 are communicated with the inside of the bearing body 2, and several introduction channels 11 can be communicated to the appropriate positions inside the bearing body 2.

[0028] Referring to Figure 3 As shown, further, a box body 12 is provided at the input end of the pump body 5. The output end of the box body 12 is connected to the input end of the pump body 5. The setting of the box body 12 ensures that there is enough grease available for input at the input end of the pump body 5, and the inside of the box body 12 is hermetically arranged, ensuring the quality of the grease during storage. Compared with storing it inside the oil tank 4 communicated with the bearing body 2, the box body 12 is more suitable for storing grease for a long time.

[0029] Referring to Figures 1 - 3 As shown, furthermore, the output end of the distributor 6 is connected to the oil tanks 4 on both sides of the drum body 3 through pipes 13. The lengths of the pipes 13 are different. According to the number of drum bodies 3, pipes 13 can be connected to other output ends of the distributor 6, and then the pipes 13 are connected to the oil tanks 4 on the corresponding bearing bodies 2, so that the pump body 5 can perform the operation of filling grease for the bearing bodies 2 on multiple drum bodies 3.
