Description

Technical Field

[0001] This utility model relates to the field of lubrication device technology, and in particular to a mining lubrication device. Background Technology

[0002] Most of the main equipment in mining enterprises such as coal mines, power plants, steel plants, and non-coal mines contains rotating parts, such as rollers, motors, and water pumps. The lubrication points of bearings and other components in the rotating parts of these equipment are usually replenished with grease manually or semi-manually.

[0003] Traditional lubrication methods in the present technology have many shortcomings due to factors such as the grease injection method, maintenance specifications, and the responsibility of personnel. For example: ① The grease injection interval is too long; ② The amount of grease injected is not easy to control. If there is too much grease, the friction pair will be damaged due to difficulty in heat dissipation; if there is too little grease, the friction pair is easily damaged due to dry friction; and some lubrication points may even be missed by human intervention; ③ The grease nipple is exposed, and dust and other substances can easily be introduced during grease injection, which will accelerate the wear of the friction pair.

[0004] Manual lubrication makes it difficult to ensure that friction pairs (such as bearings, axles, etc.) receive continuous and effective lubrication. Equipment may remain in a state of dry friction for a long time due to inadequate lubrication. In some cases, the grease fitting may be damaged or blocked, making it impossible to inject grease, which seriously affects normal operation and service life. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a mining lubrication device that can achieve automatic lubrication and extend the service life of the equipment.

[0006] The technical solution adopted in this utility model is as follows: A mining lubrication device includes a cylinder. The bottom of the cylinder is sealed to a housing assembly via a ring-shaped pad. The inside of the cylinder is connected to the inside of the housing assembly. A barrel of lubricating grease is placed in the cavity through which the grease is placed. A counterweight is provided on the top surface of the barrel of lubricating grease. Under the action of the weight of the counterweight, the barrel of lubricating grease fills the cavity. A cylinder cover is installed on the top of the cylinder. A mounting plate is fixed to the bottom of the housing assembly by fasteners. A DC motor is mounted on the bottom of the mounting plate. The output end of the DC motor is mounted on the main shaft through a bearing. The main shaft passes through the mounting plate and the housing assembly into the cavity. A cam is mounted on the head of the main shaft. A stirring blade is mounted above the cam. Grease plunger pumps are evenly spaced on the circumferential wall of the housing assembly. The head of the grease plunger pump extends into the cavity and abuts against the cam.

[0007] As a further improvement to the above technical solution: The cylinder body adopts a thin-walled cylindrical structure with open top and bottom.

[0008] The structure of the housing assembly is as follows: it includes a housing body, which is a cylindrical structure with an open top. A flange for connecting to a pad is provided on the top surface of the housing body. Multiple plunger pump mounting holes are evenly opened on the circumferential wall of the housing body. A main shaft mounting hole is provided in the middle of the housing body. Multiple locking holes are arranged around the outer ring of the main shaft mounting hole. The locking holes are fixed to the mounting plate by fasteners.

[0009] Four plunger pump mounting holes are evenly distributed on the circumferential wall of the housing body.

[0010] The housing assembly adopts a split structure, and the components are welded together.

[0011] Each grease plunger pump is equipped with a pressure sensor.

[0012] The outer diameter of the cylinder is the same as the outer diameter of the shell assembly.

[0013] The inner diameter of the cap is larger than the outer diameter of the cylinder.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, the mining lubrication device of this embodiment includes a cylinder 4. The bottom of the cylinder 4 is sealed and connected to the housing assembly 7 through a ring-shaped pad 5. The inside of the cylinder 4 is connected to the inside of the housing assembly 7, and a barrel of lubricating grease 3 is placed in the cavity through which the lubricating grease 3 is placed. A counterweight 2 is provided on the top surface of the barrel of lubricating grease 3. Under the action of the gravity of the counterweight 2, the barrel of lubricating grease 3 fills the cavity. A cylinder cover 1 is installed on the top of the cylinder 4. The bottom of the housing assembly 7 is fixed with a mounting plate 11 by fasteners. A DC motor 13 is mounted on the bottom of the mounting plate 11. The output end of the DC motor 13 is mounted with a main shaft 10 through a bearing 9. The main shaft 10 passes through the mounting plate 11 and the housing assembly 7 and enters the cavity. A cam is mounted on the head of the main shaft 10. A stirring blade 6 is mounted above the cam. Grease plunger pumps 8 are evenly spaced on the circumferential wall of the housing assembly 7. The head of the grease plunger pump 8 extends into the cavity and abuts against the cam.

[0025] The cylinder 4 adopts a thin-walled cylindrical structure with open top and bottom.

[0026] The structure of the housing assembly 7 is as follows: it includes a housing body 702, which is a cylindrical structure with an open top. A flange 701 connected to the pad block 5 is provided on the top surface of the housing body 702. Multiple plunger pump mounting holes 703 are evenly opened on the circumferential wall of the housing body 702. A spindle mounting hole 705 is provided in the middle of the housing body 702. Multiple locking holes 704 are arranged on the outer ring of the spindle mounting hole 705. The locking holes 704 are fixed to the mounting plate 11 by fasteners.

[0027] Four plunger pump mounting holes 703 are evenly opened on the circumferential wall surface of the housing body 702.

[0028] The housing assembly 7 adopts a split structure, and the components are welded together.

[0029] Each grease plunger pump 8 is equipped with a pressure sensor 12.

[0030] The outer diameter of the cylinder 4 is the same as the outer diameter of the shell assembly 7.

[0031] The inner diameter of the cap 1 is larger than the outer diameter of the cylinder 4.

[0032] In actual work process: First, a barrel of lubricating grease 3 is placed inside the cylinder 4. Under the gravity of the counterweight 2, the barrel of lubricating grease 3 fills the entire cavity inside the cylinder 4. The DC motor 13 drives the eccentric shaft (i.e., the main shaft 10) to rotate, which in turn drives the stirring blade 6 to rotate. Then, with the cooperation of the return spring of the grease plunger pump 8, the plunger is driven to reciprocate within the plunger sleeve, thereby realizing the function of the oil pump continuously delivering lubricating grease to the lubrication system of the mechanical equipment.

[0033] This embodiment adopts an advanced lubrication management system, which can greatly reduce the cost of spare parts for moving parts and the whole machine, and reduce the amount of capital tied up in inventory.
