Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the utility model structural representation.
In figure: 1, screw-threaded counterbore; 2, push rod; 21, meta boss; 3, nut; 4, round nut; 5, cylindrical shell; 6, spring II; 61, spring I; 7, open washer II; 71, open washer I; 8, cover I; 9, screw; 10, elastic washer; 11, fastening foot; 12, cover II.
Embodiment
As shown in Figure 1, a kind of cane catching machine push-and-pull automatic reset, comprises cylindrical shell 5, nut 3, cover I 8, cover II 12 and push rod 2; Cylindrical shell 5 left end outer surfaces have one section of screw thread, and cylindrical shell 5 right-hand members are inwardly provided with a circle boss; Nut 3 is arranged on cylindrical shell 5 left ends, and its left end is inwardly provided with a circle boss; The boss internal diameter of nut 3 is less than the internal diameter of cylindrical shell 5; On nut 3, be fixed with fastening foot 11, fastening foot 11 is L-type, and its one end is fixed on nut 3, and the other end has installation through hole; Cover I 8 and cover II 12 are the tubular that one end is provided with boss; On the boss of cover I 8, cover II 12, have through hole, at cylindrical shell 5 right-hand members and nut 3 left ends, have corresponding screw-threaded counterbore; Cover I 8 and cylindrical shell 5, cover II 12 is fixedly connected with elastic washer 10 by screw 9 with nut 3; Push rod 2 cooperations are arranged in cylindrical shell 5, cover I 8 and cover II 12, and push rod 2 middle parts are provided with a circle meta boss 21, and push rod 2 left ends are provided with a screw-threaded counterbore 1; On the push rod in meta boss 21 left sides, be provided with successively open washer I 71, spring I 61; Open washer I 71 is near the boss of nut 3; Spring I 61 left ends prop up open washer I 71, and spring I 61 right-hand members prop up meta boss 21; On the push rod on meta boss 21 right sides, be provided with successively spring II 6, open washer II 7; Open washer II 7 is near the boss of cylindrical shell 5; Spring II 6 left ends prop up meta boss 21, and spring II 6 right-hand members prop up open washer II 7.Cylindrical shell 5 left ends are provided with round nut 4, and round nut 4 left ends are near nut 3.
The utility model is fixed on cane catching machine correct position by fastening foot 11, and the screw-threaded counterbore of push rod 21 is connected with the pull bar of controlling cane catching machine left and right wheels, and two left and right wheels of controlling cane catching machine are installed on every cane catching machine.
When push rod 2 forward simultaneously, cover II 12 travels forward push rod 2 vertically, and spring I 61 is compressed left, and spring II 6 stretches left, and under the effect of servo-system, cane catching machine advances, and more left, forward velocity is faster for meta boss 21; When meta boss 21 is pushed into open washer I 71 places, the left side, now open washer I 71 is blocked meta boss 21 and cannot be pushed away left again, at this moment cane catching machine forward velocity reaches maximum, when unclamping push rod 2, push rod 2 is reset to immediately original state under the effect of spring force, at this moment, cane catching machine halts, wheel side speed reducer self-actuating brake.When the meta boss 21 with push rod 2 is in the neutral position of setting up, cane catching machine does not advance and does not fall back yet, and wheel side speed reducer is in self-actuating brake state.
When simultaneously to pusher push rod 2, situation is similar to the above.
When the push rod 2 pushing away forward on one side, under the effect of servo-system cane catching machine this take turns and advance, to the push rod 2 of pusher another side, under the effect of servo-system cane catching machine this take turns and retreat, 1/2 wheelbase of having realized cane catching machine turns to.
