Specific embodiment
With reference to the accompanying drawing 1, attached drawing 2 is described further the utility model.
A kind of overhead traveling crane lubrication device for wire cables, comprising: fuel tank 1, internal that lubricating oil is housed, the upper end is provided with pouring orifice
2；Pump case 4, inside along the vertical direction sliding be fitted with piston 5,5 upper end of piston is provided with vertical piston rod 6, piston 5
Completely cut off 4 inner upper end of pump case to form cavity 8,4 interior lower end of pump case is completely cut off to form oil liquid chamber 7,4 lower end of pump case is set
It is equipped with oil transportation mouth 12,4 upper end of pump case is provided with the air hole 9 being connected with cavity 8；Petroleum pipeline 3, one end is connected to fuel tank
1 bottom, the other end are connected by check valve I 11 with oil liquid chamber 7, and check valve I 11 makes the lubricating oil one-way flow in fuel tank 1
Enter into oil liquid chamber 7；Spray bar 14 is horizontally placed on the top of the winding roller 15 for being wound with wirerope 16 of overhead traveling crane, oil spout
Pipe 14 is connected by check valve II 13 with oil transportation mouth 12, is arranged at intervals with several spray orifices 24 on spray bar 14, spray orifice 24 towards around
Line roller 15, check valve II 13 are flowed into the lubricating oil in oil liquid chamber 7 unidirectionally at each spray orifice 24；And
Piston drive mechanism, driving piston rod 6 periodically move up and down.It can be infused into fuel tank 1 by pouring orifice 2
Full lubricating oil makes its drive when piston rod 6 moves down since piston drive mechanism can periodically drive piston rod 6 to move up and down
Piston 5 moves down, and since 7 volume of oil liquid chamber is gradually reduced, the closing of check valve I 11 is prevented in the state of pressure rise
Oil liquid is redirected back into fuel tank 1 in oil liquid chamber 7, and oil pressure opens check valve II 13, so that lubricating oil enters spray bar 14
In, the lubrication realized on wirerope 16 to wirerope 16 is sprayed eventually by each spray orifice 24.When piston rod 6 is with piston 5
When moving up, 7 volume of oil liquid chamber is gradually increased therefore internal generation negative pressure, and the closing of check valve II 13 prevents from sucking under suction function
Air, and the pressure of negative pressure opens check valve I 11, the lubricating oil in fuel tank 1 is entered in oil liquid chamber 7 by petroleum pipeline 3 to be realized
Oil suction.Since the volume of cavity 8 reduces when piston 5 moves up, internal gas is by the discharge of air hole 9 to equilibrium air pressure.
By periodically moving up and down for piston 5, being ejected on wirerope 16 for lubricating oil timing is realized, manpower labor is reduced
It is dynamic, it is ensured that on time to the lubrication of wirerope 16, to improve its service life.
Piston drive mechanism can be following structure comprising spring 10, the motor 17, installation being set on piston rod 6
In on 17 output shaft of motor gear I 18, horizontally rotate by rolling bearing units 23 installation shaft 19, be installed in shaft 19
And the gear II 20 being meshed with gear I 18 and the cam 21 for being installed on 19 head end of shaft, the head end and cam of piston rod 6
21 are in contact, and when cam 21, which turns to lowest point, to be in contact with the head end of piston rod 6, spring 10 is in free state,
The lower end of spring 10 is connected with piston 5, and the upper end is connected with pump case 4.Motor 17 rotates it and gear I 18 is driven to rotate,
Since the number of teeth of gear I 18 is less than the number of teeth of gear II 20, driving gear II 20 reaches slowing effect when rotating,
By be rationally arranged gear II 20 in the reduction ratio of gear I 18 can reasonably control injection lubricating oil time cycle.Tooth
Take turns II 20 rotation when driving cam 21 rotate, when the bigger diameter end of cam 21 turns to bottom its pull down piston rod 6 to
Spring 10 into spray bar 14, is stretched the lubricating oil pressurized delivered in oil liquid chamber 7 by bottom, piston 5 when piston 5 moves down.
When the miner diameter end of cam 21 turns to bottom, 10 releasability of spring driving piston 5 move up realize piston 5 reset and
Make to fill lubricating oil again in oil liquid chamber 7.
It preferably, further include being rotatablely installed in the roller 22 on 6 top of piston rod, cam 21 connects with 22 rolling friction of roller
Touching.Since cam 21 is in rotation, roller 22 can be rolled along 21 outer surface of cam, be rubbed so that rolling is changed into sliding friction
It wipes, reduces frictional force, prevent the abrasion of cam 21 Yu piston rod 6, improve service life.
