The present application belongs to the technical field of steel wire rope, and discloses a steel wire rope inspection and maintenance device of a portal crane. A fixed end is arranged on a hanging beam of the portal crane, one end of the steel wire rope is arranged at the fixed end, and the other end is connected to a winch through a movable pulley. The inspection and maintenance device comprises a body assembly, an oil scraping assembly and a camera. The body assembly comprises a first bell mouth structure, a first connecting pipe and a second bell mouth structure connected in sequence. The steel wire rope can be arranged in the body assembly. The body assembly can be fixed to the shell of the movable pulley. The winch is rotated to move the body assembly. The first bell mouth structure is used for accommodating the lubricating grease. The oil scraping assembly is arranged on the first bell mouth structure. When the body assembly moves downward, the oil scraping assembly is used for scraping off the excess lubricating grease on the steel wire rope. The camera is arranged on the first bell mouth structure. The camera is used for shooting the position above the oil scraping assembly and transmitting the shooting information back to a terminal information receiving device, thereby reducing the difficulty and cost of inspection and maintenance.

The utility model relates to a kind of friction clutch structure for realizing braking by pneumatics, belong to the technical field of friction braking mechanism, including rotating shaft, the rotating shaft is equipped with transmission disc, the transmission disc side is equipped with with rotating shaft movable sleeve joint's brake pressure disc, the transmission disc and brake pressure disc between being equipped with friction plate, the friction plate is equipped with several annular distribution and with transmission disc screw thread type sleeve joint fixed counterbore screw, the transmission disc and rotating shaft between being equipped with spring that drive brake pressure disc is reset.With compact structure, operating stability is good and the characteristics of long service life.Adopt the design of thrust ball bearing, solve the friction wear problem between rotating component and stationary actuator.By air pressure to generate braking force, make transmission disc and friction plate combine, to realize braking;When air pressure disappears, through spring force to make component separate, restore transmission.
