Description

Technical Field

[0001] This utility model relates to the technical field of bridge crane main hook brakes, specifically an automatic lubrication device for the cross shaft hinge point of a bridge crane main hook brake. Background Technology

[0002] The cross shaft of the main hook brake of the bridge crane wears down due to frequent operation, leading to brake failure and various adverse consequences. After prolonged use, the braking effect will fail, requiring more time for maintenance, with each maintenance session lasting up to 4 hours, delaying production. At the same time, prolonged use will also shorten the lifespan of the parts on the main hook brake of the bridge crane.

When the adjusting nut 212 is rotated, the pressure of the telescopic spring 210 on the movable plug 206 can be adjusted.

[0022] The connecting sleeve 208, connecting baffle 209, connecting rod 211, and adjusting nut 212 are integrated into one piece. The center lines of the connecting sleeve 208, connecting baffle 209, connecting rod 211, and adjusting nut 212 are aligned. One end of the oil passage tamping rod 216 passes through the adjusting nut 212, connecting rod 211, connecting baffle 209, connecting sleeve 208, connecting rod 207, movable plug 206, and drip pipe 202 in sequence. A sealing ring is provided on the wall of the connecting rod 211 corresponding to the oil passage tamping rod 216. A vent hole is provided at the center of the sealing plug 219 to prevent oil passage blockage when the oil passage tamping rod 216 is pulled.

[0023] When using the automatic lubrication device for the cross shaft hinge point of the main hook brake of the bridge crane, firstly, two concentric holes with diameters of 10 mm and 5 mm respectively are drilled in the connecting plate of the cross shaft 1 of the main hook brake of the bridge crane, reaching the center of the shaft and the bushing, so that the lubricating oil in the adjustable automatic lubrication structure 2 can seep into the bushing.

By manually rotating the adjusting nut 212, the connecting rod 211, the connecting baffle 209, and the connecting sleeve 208 will rotate. At the same time, the adjusting nut 212 and the connecting threaded tube 208 will rotate. Under the action of 13, the distance between the adjusting nut 212 and the connecting threaded pipe 213 is adjusted. When the distance between the adjusting nut 212 and the connecting threaded pipe 213 is changed, the distance between the movable plug 206 and the connecting baffle 209 can be changed, thereby changing the pressure of the telescopic spring 210 on the movable plug 206, so that the gap between the oil dripping pipe 202 and the movable plug 206 is adjusted, thereby controlling the flow rate and speed of lubricating oil seepage in the oil storage tank 201. When the oil passage tamping rod 216 is manually pulled and released, the oil passage tamping rod 216 is driven to move quickly under the action of the connecting spring 214, thereby preventing the oil passage from being blocked.
