Description

Technical Field

[0001] This utility model relates to the technical field of oil injection devices, specifically to an oil injection device for sintering trolley wheels. Background Technology

[0002] In the steel industry, sintering is an essential step. Before blast furnace ironmaking, various powdered iron-containing raw materials are mixed with appropriate amounts of fuel and flux, and an appropriate amount of water is added. After mixing and pelletizing, the materials undergo a series of physicochemical changes on sintering equipment, sintering into blocks to form raw materials for ironmaking.

[0003] The sintering trolley is the main operating component of the sintering machine. Its main function is to form a rotating chain between the head and tail wheels of the sintering machine. It receives the sintering mixture in the upper horizontal section, and after preheating, ignition, sintering, cooling, and turning, it returns to the head wheel, forming a transmission cycle to achieve the purpose of sintering the material. During the operation of the sintering trolley, it is necessary to regularly lubricate the wheels to ensure good lubrication. The ends of the wheels are equipped with outward-protruding oil nozzles for injecting lubricating oil.

[0004] The current method of lubricating sintering trolleys involves manually adding grease after the trolley stops. However, dust such as iron powder and shavings generated during the operation of the sintering trolley, as well as the dried material formed by the lubricating oil mixing with dust under high temperatures, can easily enter the bearing assembly along with the lubricating oil during the injection process. This not only easily leads to inadequate lubrication of the bearing assembly but also causes wear on the wheels and axles. Furthermore, the sintering trolley, operating in a scorching environment, is more prone to wheel deformation under wear conditions, accelerating axle wear and ultimately causing the wheels to seize up, necessitating wheel replacement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an oil injection device for sintering trolley wheels, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An oil injection device for sintering trolley wheels includes a trolley guide rail, a base on one side of the trolley guide rail, a follower platform on the top end face of the base, baffles on the top end faces of the base on both sides of the follower platform, a connecting screw screwed between the two baffles, a follower motor with its output end connected to the connecting screw screw on the outer end face of one baffle, a bearing platform above the follower platform, a fixing plate on the follower platform on both sides of the bearing platform, a drive cylinder with its output end connected to the bearing platform on the outer end face of one fixing plate, and a cleaning mechanism and an oil injection mechanism respectively on the top end face of the bearing platform.

[0008] The cleaning mechanism includes a cleaning cylinder, a mounting base at the front end of the cleaning cylinder, a travel groove in the mounting base, a travel block slidably disposed in the travel groove and connected to the output end of the cleaning cylinder, a cleaning motor on the top of the travel block, and a flexible cleaning brush on the rotating shaft of the cleaning motor.

[0009] The oil injection mechanism includes an oil injection cylinder, a rotary joint is provided on the output end of the oil injection cylinder, and an oil gun is provided at the end of the rotary joint away from the oil injection cylinder.

[0010] As a preferred technical solution of this utility model, the top end face of the base is provided with two oppositely arranged guide rails, and the bottom end face of the follower platform is provided with a guide rail groove adapted to the guide rails.

[0011] The above technical solution, through the matching of guide rail groove and guide rail, ensures the stability of the displacement of the follow-up platform.

[0012] As a preferred technical solution of this utility model, a plurality of sliding rods that are slidably connected to the bearing platform are provided between the two fixed plates.

[0013] By employing the above technical solution and utilizing the arrangement of multiple sliding rods, the stability of the displacement of the load-bearing platform driven by the drive cylinder is ensured.

[0014] As a preferred embodiment of this utility model, guide blocks are symmetrically arranged on both sides of the traveling block, and a guide groove for displacement of the guide blocks is provided on the inner side wall of the traveling groove.

[0015] The above technical solution, by using the guide groove and guide block, ensures the stability of the sweeping cylinder driving the traveling block and the flexible cleaning brush.

[0016] As a preferred technical solution of this utility model, a grease pump is provided on one side of the base, and a grease delivery hose connected to the rotary joint is provided on the grease pump.

[0017] In a preferred embodiment of this invention, the refueling nozzle is mounted on a support platform via a nozzle sleeve.

[0018] The above technical solution utilizes the design of the oil gun sleeve to protect and secure the oil gun.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] When it is necessary to lubricate the wheels of the trolley, start the follower motor to drive the follower platform to move synchronously and at the same speed as the trolley. The displacement of the follower platform causes the cleaning mechanism and the lubrication mechanism to move accordingly. During the synchronous movement of the follower platform, the flexible cleaning brush on the cleaning mechanism is aligned with the oil nozzle on the trolley wheel. Start the cleaning cylinder to push the travel block to move towards the oil nozzle, so that the flexible cleaning brush contacts and presses against the oil nozzle. Start the cleaning motor to drive the flexible cleaning brush to rotate and remove the solidified dried material and dust on the oil nozzle. After cleaning is completed, the cleaning mechanism is reset.

[0021] Then, the drive cylinder is activated to move the support platform, aligning the grease gun with the cleaned grease nozzle. The grease injection cylinder is then activated to push the grease gun forward, ensuring the nozzle firmly presses against the cleaned nozzle to form a seal. The grease pump starts, supplying grease to the grease gun through the grease delivery hose and rotary joint, completing the grease injection for this trolley wheel. The follower motor then drives the follower platform to reset and move to the next trolley wheel to be processed, repeating the above process. This invention allows for grease injection following the movement of the trolley, improving the effective operating rate of the sintering machine. Simultaneously, it cleans the grease nozzles on the trolley wheels before grease injection, ensuring the injected grease is clean and avoiding the risk of introducing external contaminants into the bearings during grease injection.

Start the cleaning cylinder 401 to push the travel block 405 to move towards the oil nozzle, so that the flexible cleaning brush 406 contacts and presses against the oil nozzle. Start the cleaning motor 404 to drive the flexible cleaning brush 406 to rotate and remove the solidified dried material and dust on the oil nozzle. After cleaning is completed, the cleaning mechanism 4 is reset.

[0043] Subsequently, the drive cylinder 12 is activated to move the support platform 16, aligning the grease gun 503 with the cleaned grease nozzle. The grease injection cylinder 501 is then activated to push the grease gun 503 forward, ensuring the nozzle of the grease gun 503 firmly presses against the cleaned grease nozzle, forming a seal. The grease pump 6 is activated, supplying grease to the grease gun 503 through the grease delivery hose 7 and the rotary joint 502, completing the grease injection operation for this trolley wheel. Then, the follower motor 8 drives the follower platform 3 to reset and move to the next trolley wheel to be processed, repeating the above process. This invention can perform grease injection operations following the movement of the trolley, improving the effective operating rate of the sintering machine. Simultaneously, it can clean the grease nozzles of the trolley wheels before grease injection, ensuring the injected grease is clean and avoiding the risk of introducing external contaminants into the bearings during grease injection.
