Description

Technical Field

[0001] This utility model relates to the field of self-lubrication of crane drive equipment, and in particular to a self-lubrication device for crane drive equipment. Background Technology

[0002] As an indispensable large-scale mechanical equipment in modern industry and construction, the performance of the driving equipment of cranes directly affects the operating efficiency and safety of the entire crane system. With the advancement of technology, the design of cranes has been continuously optimized, evolving from the initial steam drive to various drive forms such as electric and hydraulic, and gradually realizing automated and intelligent operation.

[0003] A search revealed a Chinese patent disclosure for a self-lubricating structure for a crane trolley drive device (Authorization Announcement No.: CN218913679U). This utility model discloses a self-lubricating structure for a crane trolley drive device, relating to the field of crane lubrication technology. Specifically, it includes a main beam, a rail fixedly connected to the top of the main beam, a slider slidably connected to the top of the rail, an end beam fixedly connected to the top of the slider, a fixing plate fixedly connected to one side of the end beam, and a first motor fixedly connected to one side of the fixing plate. This self-lubricating structure for a crane trolley drive device, through the coordinated arrangement of the fixing plate, the first motor, the first gear, the rack, the arc-shaped protrusion, the lubrication hole, the rotating ball, and the first spring, allows the arc-shaped protrusion to press upwards against the rotating ball during use. Lubricating oil flows down from the gaps around the rotating ball to lubricate the first gear and the rack, thus continuously lubricating the first gear and rack, reducing manual operation and increasing the automation of the device.

[0004] However, in practical applications, existing crane drive lubrication systems typically employ a centralized lubrication design, using one or more lubrication pumps to deliver lubricating oil to various points requiring lubrication. While this method can ensure adequate lubrication at each point to some extent, it still has several shortcomings. First, due to the unique working environment of cranes, such as large temperature variations and high dust levels, the fluidity of the lubricating oil is affected, potentially leading to poor lubrication.

[0007] The lubrication mechanism includes an oil pump, a delivery pipe, a connecting pipe, and a support plate. The support plate is located inside the storage tank, the oil pump is installed on top of the support plate, one end of the delivery pipe is connected to the oil pump, and one end of the connecting pipe is connected to the oil pump.

[0024] Reference Figure 1-5 An embodiment of this utility model is provided: a self-lubricating device for a crane drive equipment, including a base plate 1, a fixing mechanism 6 provided on the top of the base plate 1, a storage box 2 provided on the top of the base plate 1, a lubrication mechanism 4 provided inside the storage box 2, and a guide mechanism 5 provided on one side of the storage box 2.

[0025] The lubrication mechanism 4 includes an oil pump 401, a delivery pipe 402, a connecting pipe 403, and a support plate 404. The support plate 404 is located inside the storage tank 2.

[0026] Through the above technical solution, by setting up a lubrication mechanism 4, the oil inside the storage tank 2 is transferred to the inside of the delivery pipe 402 through the connecting pipe 403 by the oil pump 401, and then transferred to the lubrication plate 504 by the delivery pipe 402. As needed, an appropriate amount of lubricating oil is transferred from the storage tank 2 to each lubrication point, which improves lubrication efficiency, reduces lubricating oil waste, thereby extending the service life of the equipment and reducing operating costs.

[0027] Specifically, the guide mechanism 5 includes a hydraulic rod 501, a fixing block 502, a positioning block 503, and two lubrication plates 504. The two lubrication plates 504 are respectively disposed on one side of the fixing block 502 and the positioning block 503. The output end of the hydraulic rod 501 is disposed on one side of the storage box 2. The output end of the hydraulic rod 501 is fixedly connected to the positioning block 503. Both the fixing block 502 and the positioning block 503 are disposed on one side of the storage box 2.

[0028] Through the above technical solution, by setting the guide mechanism 5, the positioning block 503 is moved by the output end of the hydraulic rod 501, the distance between the fixed block 502 and the positioning block 503 can be adjusted, and the crane drive equipment is lubricated.

[0029] Specifically, the fixing mechanism 6 includes a base 601, a positioning plate 602, a fixing plate 603, and a bolt 604. One side of the bolt 604 passes through the fixing plate 603 and is rotatably connected to the positioning plate 602. The fixing plate 603 is fixed to the top of the base 601, the positioning plate 602 is set on the top of the base 601, and the base 601 is set on the top of the base plate 1.

[0030] Through the above technical solution, by setting the fixing mechanism 6, the crane drive equipment is placed on the base 601, and the rotating bolt 604 drives the positioning plate 602 to move closer to the crane drive equipment. When the positioning plate 602 and the crane drive equipment come into contact, the crane drive equipment can be fixed.

[0031] Specifically, a spring 3 is fixedly connected to the bottom of the fixing block 502, and a telescopic rod 7 is provided inside the spring 3. One side of the telescopic rod 7 is fixedly connected to the lubrication plate 504.

[0032] Through the above technical solution, by setting spring 3 and telescopic rod 7, when the positioning block 503 moves, it drives spring 3 to extend and retract, and telescopic rod 7 is also stretched accordingly, which plays a buffering role in the lubrication of the crane drive equipment.

[0033] Specifically, dovetail blocks 8 are fixedly connected to both sides of the fixed block 502, and dovetail grooves 9 are opened on both sides of the storage box 2. The dovetail blocks 8 and the dovetail grooves 9 are slidably connected internally.

[0035] Specifically, the base 601 has sliding grooves 11 on both sides of the top, and the bottom of the positioning plate 602 is fixedly connected to a slider 10, which is slidably connected to the inside of the sliding groove 11.

[0036] Through the above technical solution, by setting the slide groove 11 and the slider 10, the slider 10 is driven to move inside the slide groove 11 when the positioning plate 602 moves, which plays a stabilizing role in the movement of the positioning plate 602.

[0037] Working Principle: During operation, the output end of the hydraulic rod 501 drives the positioning block 503 to move, adjusting the distance between the fixed block 502 and the positioning block 503. The crane drive equipment is lubricated by the oil pump 401, which transfers the oil from the storage tank 2 to the delivery pipe 402 via the connecting pipe 403. From there, the oil is transferred to the lubrication plate 504. Appropriate amounts of lubricating oil are delivered from the storage tank 2 to each lubrication point as needed, improving lubrication efficiency, reducing oil waste, extending equipment lifespan, and lowering operating costs. The crane drive equipment is placed on the base 601, and the bolt 6 is rotated... 04. The positioning plate 602 is moved closer to the crane drive equipment. When the positioning plate 602 contacts the crane drive equipment, it can fix the crane drive equipment. When the positioning block 503 moves, it drives the spring 3 to extend and retract, and the telescopic rod 7 is also stretched, which plays a buffering role in lubricating the crane drive equipment. When the positioning block 503 moves, it drives the dovetail block 8 to move inside the dovetail groove 9, which plays a stabilizing role in the movement of the positioning block 503. When the positioning plate 602 moves, it drives the slider 10 to move inside the slide groove 11, which plays a stabilizing role in the movement of the positioning plate 602.
