Embodiment
Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2,3,4,5,6,7, shown in 8, a kind of clutch and adopt the middle vacuum circuit breaker chassis car of this clutch, comprise vehicle frame 1 and the driving wheel 2 of being located at vehicle frame 1 both sides, the handle 4 that described vehicle frame 1 is provided with screw mandrel 3 and removably connects with screw mandrel 3, described vehicle frame 1 is provided with control module 5 and electronic module 6, described control module 5 is provided with the port that communication connects, described remote worker is by the electronic module 6 of control module 5 controls, thereby control pushing or withdrawing from of chassis car, described electronic module 6 comprises drive motor 61 and sensitive switch 62, sensitive switch 62 be arranged so that chassis car movement process is more accurate.Described drive motor 61 links by clutch 7 and screw mandrel 3, and described clutch 7 comprises rotating shaft 71, axle sleeve 72 and drive wheel 73, and drive wheel 73 can be gear, sprocket wheel etc.Described axle sleeve 72 is sheathed in the rotating shaft 71, described drive wheel 73 be sheathed on the axle sleeve 72 be used for screw mandrel 3 on follower 31 be connected, the footpath of described rotating shaft 71 upwards is provided with a plurality of mounting grooves 711, the corresponding ball 74 that arranges in each mounting groove 711, described axle sleeve 72 is provided with and mounting groove 711 slotted eye 721 one to one, the inwall of described drive wheel 73 is recessed to form and mounting groove 711 corresponding groove 732, the rotational resistance of described rotating shaft 71 is less than axle sleeve 72 rotational resistances, described ball 74 have pass the primary importance that slotted eye 721 makes that rotating shaft 71 and drive wheel 73 circumferentially are linked and fall into mounting groove 711 and slotted eye 721 between make rotating shaft 71 and drive wheel 73 releases the second place.When the car of manual promotion chassis, can replace with handle, ball is in the second place, and (ball also is in the second place during nature, as shown in Figure 7), this moment, the drive wheel rotation ball was crushed in the mounting groove, by shaking handle, realized pushing or withdrawing from of chassis car thereby make screw mandrel move; When electronic module promotes the chassis car, the driven driven by motor rotation of rotating shaft this moment, because the rotational resistance of rotating shaft is less than the axle sleeve rotational resistance, making ball move until the groove with drive wheel along the mounting groove edge from the bottom of mounting groove blocks mutually, this moment, ball dropped on mounting groove respectively, in slotted eye and the groove, ball is in primary importance (as shown in Figure 6), make rotating shaft and drive wheel link, follower on the drive wheel rotating band movable wire bar rotates, follower cooperates with the screw mandrel rotation, the rotation of follower is converted into the axial displacement of screw mandrel, thereby realizes pushing or withdrawing from of chassis car.The invention has the beneficial effects as follows that the drive wheel that adopts drive motor to drive on the clutch rotates, rotate thereby drive follower that follower makes screw mandrel move axially, thereby makes the chassis car be pushed into or withdraw from, and is relatively simple for structure, car motion in chassis is reliable.And the clutch configuration among the present invention is simple, volume is little, production, easy to assembly, the space that takies the chassis car is little, be convenient to the installation of other component, can be so that control module be built on the car of chassis, the potential safety hazard of avoiding the own wiring of user to exist, when clutch is installed on the car of middle vacuum circuit breaker chassis, can realize the moving and switching automatically of chassis driver fast, simply, reliably, can realize on the spot or distant place control middle vacuum circuit breaker handcart pushes or exit function, increase substantially the power supply safety reliability.
Described rotating shaft 71 is provided with driven sprocket 77, described driven sprocket 77 is by bearing pin 78 and rotating shaft 71 Joints, specifically, the sidewall of driven sprocket 77 extends sprocket wheel cover 79, described bearing pin 78 passes sprocket wheel cover 79 and rotating shaft 71 successively, and realization rotating shaft 71 is fixedlyed connected with driven sprocket 77.Described driven sprocket 77 links by the drive sprocket 612 on chain 611 and the drive motor 61.Driven sprocket be arranged so that this use novel can better with the interlock of the drive sprocket of drive motor, rotate thereby drive rotating shaft.Certainly, can also drive the rotating shaft rotation by other means, realize the variation of ball position.
Described mounting groove 711 has three and be arranged on uniformly on the circumference of rotating shaft 71 outer walls.Described mounting groove 711 is cone tank.Mounting groove is that cone tank makes ball from the primary importance to the second place; The second place is more steady to the primary importance transition, makes clutch reliable.Three mounting grooves and even circumference are arranged on and make in the rotating shaft that product is easy to process, and ball is easy for installation, and clutch is reliable.Certainly, can be two, four, five etc. according to the quantity of actual conditions mounting groove.
Be equipped with circular groove 722 on the two ends of described axle sleeve 72, be respectively equipped with snap ring 75 and collar 76 in the described circular groove 722, the axial displacement of drive wheel has been avoided in the setting of collar 76, described snap ring 75 comprises the card-tight part 751 that blocks mutually with circular groove 722 and is used for hard-wired tension portion 752 that described card-tight part 751 and tension portion 752 are integral structure.Such structure increases the rotational resistance of axle sleeve, can certainly realize the purpose of the rotational resistance of increase axle sleeve by the roughness that increases axle sleeve outer wall and drive wheel inwall, thereby make that ball can move to primary importance reliably from the second place when the driven driven by motor of rotating shaft was rotated.
Described drive motor 61 horizontal installations (the vertical installation of mentioning in the background technique relatively) are in the cavity of vehicle frame 1.Such structure makes the level height of drive motor a little more than the level height of vehicle frame, does not need original frame structure of circuit breaker is transformed, and greatly reduces cost of production, makes motor to be installed in the chassis frame.
Every technician's notice: though the present invention describes according to above-mentioned embodiment, invention thought of the present invention is not limited in this invention, and the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
