Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
The wire body jack of a kind of lowering or hoisting gear as shown in Figure 1, Figure 2 and shown in Fig. 3, including housing 100, reel 30, drive mechanism and rotation preventive mechanism, being formed with a cavity in housing 100, above-mentioned reel 30, drive mechanism and rotation preventive mechanism are installed in cavity.Concrete drive mechanism includes the first rotary shaft 10 and the second rotary shaft 20, first rotary shaft 10 is articulated in cavity and can be around own axis, in the second same rotary shaft 20 is articulated in cavity and can be around own axis, and second rotary shaft 20 synchronize be connected in the first rotary shaft 10, the i.e. first rotary shaft 10 can drive the second rotary shaft 20 to rotate when rotating.Additionally, the rotation direction of the second rotary shaft 20 can be identical or contrary with the rotation direction of the first rotary shaft 10.It addition, above-mentioned reel 30 is fixedly connected in the second rotary shaft 20.
Above-mentioned rotation preventive mechanism includes spline dish 40 and spline part 50, spline dish 40 is fixed in the second rotary shaft 20, spline part 50 is then connected on cavity inner wall, this spline part 50 for abut when the rotation direction of the second rotary shaft 20 is identical with the rotation direction of the first rotary shaft 10 to end rotating disk 40, to limit the rotation of spline dish 40.
On the basis of said structure, when utilizing the wire body jack of the present invention to carry out folding and unfolding wire body, can first by wire body around being located on reel 30, then driven the rotation of reel 30 by drive mechanism, thus carry out the folding and unfolding of wire body.The most in the present embodiment, when lowering or hoisting gear power effect outside rises, when i.e. needing to carry out payoff operation, the first rotary shaft 10 is made to rotate clockwise, thus drive the second rotary shaft 20 direction around rotating counterclockwise, thus rotate around rotating counterclockwise as well as second with the second fixing reel 30 being connected of rotary shaft 20, owing to the rotation direction of now the first rotary shaft 10 is contrary with the rotation direction of the second rotary shaft 20, therefore rotation preventive mechanism will not work, the second rotary shaft 20 so rotated just can drive reel 30 to rotate, thus wire body can be released, lowering or hoisting gear is made to increase smoothly.
And when lowering or hoisting gear declines, when i.e. needing to regain wire body, now due to the existence of External Force Acting, reel 30 may follow rotation direction during unwrapping wire to walk, i.e. reel 30 can be around rotating counterclockwise in the case of External Force Acting is relatively big, now the rotation direction of the second rotary shaft 20 is identical with the rotation direction of the first rotary shaft 10, in the case, spline part 50 just can abut rotating disk 40 to end to limit the rotation of spline dish 40, when spline dish 40 stops operating, continue to make the first rotary shaft 10 rotate counterclockwise, the rotation direction of the second rotary shaft 20 just can continue to be driven by the first rotary shaft 10 to rotate clockwise, i.e. contrary with turning to of the first rotary shaft 10, just take-up can be continued, so that lowering or hoisting gear is fallen smoothly.
Preferably, the first gear 11 can be installed with in the end of the first rotary shaft 10, it is installed with the second gear 21 accordingly in the end of the second rotary shaft 20, this second gear 21 is made to engage with described first gear 11, so can be by the rotation rotating drive the second rotary shaft 20 of the first rotary shaft 10, and first rotary shaft 10 and the second rotary shaft 20 be to be coupled by gear synchronous, therefore rotating of the second rotary shaft 20 can be contrary with the rotation direction of the first rotary shaft 10.And above-mentioned reel 30 is fixedly arranged on the second rotary shaft 20 one end away from the second gear 21, spline dish 40, between the second gear 21 and reel 30, convenient is installed and operation.
