For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each embodiment of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
First embodiment of the present utility model relates to a kind of withdrawing rope mechanism, comprises at least one pair of drum mechanism built and dynamical axis 4, the one-way wheel mechanism that each drum mechanism built comprises reel 1 and is connected with reel 1, and one-way wheel mechanism is connected with dynamical axis 4; Wherein, when dynamical axis 4 rotates towards a direction, one-way wheel mechanism band movable reel 1 rotates, and when dynamical axis 4 rotates to another way, one-way wheel mechanism is in free state; Further, in a pair drum mechanism built, when there being a drum mechanism built to rotate by dynamical axis drives, another drum mechanism built is in free state.
In the present embodiment, this paired drum mechanism built is divided on two motor shafts 4.Now, stay cord can connect the two ends of two reels 1 respectively, and the connection mode of stay cord is comparatively simple, does not have structural requirement to table top to be cleaned, has the advantage being convenient to arrange.
As can be seen from Figure 1, in the present embodiment, one-way wheel mechanism comprises power wheel 2 and eccentric pushing block 3; Wherein, eccentric pushing block 3 is connected with dynamical axis 4, and eccentric pushing block 3 is in transmission connection with power wheel 2, and power wheel 2 is connected with reel 1.When eccentric pushing block 3 rotates to a direction, eccentric pushing block 3 drives power wheel 2 rotating in same direction, and when eccentric pushing block 3 rotates to another direction, eccentric pushing block 3 is in free state; Power wheel 2 is connected with reel 1.Drive power wheel 2 to rotate by arranging eccentric pushing block 3, its structure is simple, and realizability is strong.Further, in the present embodiment, the axle center place of eccentric pushing block 3 is provided with ratchet 5; Further, this ratchet 5 is connected with dynamical axis 4, and when ratchet 5 rotates towards a direction, this ratchet 5 drives eccentric pushing block 3 rotating in same direction, and when ratchet 5 rotates to another way, ratchet 5 is in free state.
In the present embodiment, ratchet 5 is provided with ratchet, is provided with ball 6 between the gap of ratchet and eccentric pushing block 3; Dynamical axis 4 bias, through power wheel 2, is connected with the center of ratchet 5.As shown in Figure 1, in the present embodiment, this ratchet is 1.Obviously, ratchet quantity should not be only limitted to 1, and more ratchet also can meet technical requirements of the present utility model.
When dynamical axis 4 rotates towards the active direction (in FIG for anticlockwise direction) of one-way wheel mechanism, ratchet 5 is driven to rotate, the ratchet of ratchet 5 will promote ball 6, again because dynamical axis 4 bias is through this power wheel 2, therefore ball 6 is in the inner side at eccentric pushing block 3 that is stuck, and eccentric pushing block 3 is and then rotated, when eccentric pushing block 3 rotates to after certain distance, power wheel 2 will be oppressed, and force power wheel 2 to follow rotation.When dynamical axis 4 rotates towards the driven direction (in FIG for clockwise direction) of one-way wheel, because promotion ball 6 resets by ratchet, and ball 6 and ratchet 5 are rotated jointly, do not have influence on the motion of eccentric pushing block 3, now, eccentric pushing block 3 will not come in contact with the limit wall 21 of power wheel 2, and power wheel 2 will be in free state.
In the present embodiment, can be connected by flat key between ratchet 5 with described dynamical axis 4.Flat key has good advantage in expression torque, and changeing of very convenient ratchet 5, be convenient to maintenance and safeguard.
In the present embodiment, eccentric pushing block 3 comprises major diameter part and the minor axis part of coaxial setting, and ratchet 5 is located on the axle of eccentric pushing block 3, and major diameter part is rotated for driving power wheel 2.Select eccentric pushing block 3 with line of apsides part for other forms of eccentric pushing block 3, and between the inner ring of power wheel 2, there is larger area of contact, extend the life-span of operation.Certainly, the eccentric pushing block 3 of other shapes is selected also not affect utility model object of the present utility model.
In the present embodiment, the inner ring of power wheel 2 is provided with grooving, and this grooving is positioned at the contact position of power wheel 2 with eccentric pushing block 3, and this grooving significantly can increase eccentric pushing block 3 and the area of contact of power wheel 2 inner ring, improves service life and the stability of equipment.Get on very well further, elastic layer 7 can also be set up at grooving place, thus play buffer action.This grooving can be set as shape as shown in Figure 1, more can be set as the shape of eccentric pushing block 3 contact surface of fitting, thus increase area of contact further, reduces impulsive force during contact.Certainly, the inner ring of power wheel 2 also can not establish grooving, and this does not affect utility model object of the present utility model.
In the present embodiment, if if the radius of minor axis part is R1, the radius of major diameter part is R2, and the internal diameter of power wheel 2 limit wall 21 is R3, and the distance at power wheel 2 center and dynamical axis 4 center is r; Then can there is following dimensional parameters: R2>R3-r1; R2<R3+r1; R1<R3-r1.When three is under this size, the operation of drum mechanism built is reliable.
In terms of existing technologies, the reel 1 of the withdrawing rope mechanism that present embodiment provides arranges and is serially connected on same dynamical axis 4 in pairs, save the quantity required of dynamical axis 4, and, because power resources are in same dynamical axis 4, the linear velocity of following the asynchronous running of dynamical axis 4 to cause therefore can be prevented inconsistent, and equipment operation portion determines that factor increases more, the problems such as equipment life is short, improve the stability that equipment runs.
In terms of existing technologies, the withdrawing rope mechanism that embodiment of the present utility model provides is when dynamical axis 4 rotation direction is different, reel 1 will be in rope closing state respectively or put rope (freedom) state, and be in the drum mechanism built of putting rope form state, its linear velocity of putting rope by with the connected drum mechanism built Auto-matching being in rope closing state.By arranging the contrary drum mechanism built of both direction, drum mechanism built can be solved and rotate nonsynchronous technical matters, and improve the stability of trolley travelling, prevent engine installation from burning out.
Second embodiment of the present utility model relates to a kind of withdrawing rope mechanism, second embodiment is slightly different from the first embodiment, main difference part is, in the second embodiment of the present utility model: paired drum mechanism built is located on two motor shafts 4 respectively.
Such as, in the technical scheme that such as Fig. 2 shows, by stacking in opposite directions for two identical drum mechanism built of inner structure, and pass from same dynamical axis 4.Thus, when the state that the reel 1 in left side in Fig. 2 rotates in driving, the reel 1 on right side will be in free rotation state, when the state that the reel 1 on right side in Fig. 2 rotates in driving, the reel 1 in left side will be in free rotation state, further, the driving hand of rotation of these two reels 1 is just in time contrary.By the reel 1 that both direction is similar, the crank motion of the same stay cord be around on the two can be realized.Certainly, the drum mechanism built that also can be by two inner structures designed in mirror image is stacking in the same way, and passes from same motor shaft 4, also can realize identical technique effect.
Now, same stay cord is by after guide wheel, and two ends connect two reels respectively, only need can drive dolly crank motion by a motor shaft 4, have saved the quantity of dynamical axis 4, improve the stability that equipment runs.
As shown in Figure 3,3rd embodiment of the present utility model relates to a kind of withdrawing rope mechanism, 3rd embodiment is the further improvement of first, second embodiment, main improvements are, in the 3rd embodiment of the present utility model: power wheel 2 comprises chassis 22 and the limit wall 21 with chassis 22 side edge, dynamical axis 4 bias is through chassis 22; Chassis 22 and limit wall 21 with the center shaft of power wheel 2 for S. A. is rotatably connected; Reel 1 is connected with limit wall 21.And power wheel 2 is provided with blocking mechanism 8, blocking mechanism 8 is for stopping the unidirectional rotation of eccentric pushing block 3 relative to power wheel 2.
In the present embodiment, as shown in Figure 3, this blocking mechanism 8 is backing pin.Obviously, this blocking mechanism 8 also can be other any mechanisms that can stop eccentric pushing block 3 unidirectional rotation, and such as baffle plate, interlayer etc., these do not affect the realization of technical solutions of the utility model.Further, the surface of this blocking mechanism 8 still also can arrange cushion layer, thus buffering eccentric pushing block 3 and the impact that formed between it, the service life of extension device.
When ball 6 lost efficacy, because blocking mechanism 8 is located at chassis 22, therefore eccentric pushing block 3 will with chassis 22 synchronous rotary, the S. A. due to the two is chassis 22, the namely center shaft of power wheel 2, therefore eccentric pushing block 3 will not come in contact with the limit wall 21 of power wheel 2.Therefore adding relative to the rotatable chassis 22 of limit wall 21, and after being located at the blocking mechanism 8 on chassis 22, safety effect can played to the operation of system.
As shown in Figure 4,4th embodiment of the present utility model relates to a kind of withdrawing rope mechanism, 4th embodiment is slightly different from aforementioned three kinds of embodiments, and main difference part is, in the 4th embodiment of the present utility model: ratchet 5 is not established in the axle center of eccentric pushing block 3.Now, power wheel 2 comprises chassis 22 and the limit wall 21 with chassis 22 side edge, and chassis 22 and limit wall 21 are with the center shaft of power wheel 2 for S. A. is rotatably connected, and reel 1 is connected with limit wall 21; Further, eccentric pushing block 3 comprises major diameter part and the minor axis part of coaxial setting, and dynamical axis 4 bias is through chassis 22, and be connected with the axle center of eccentric pushing block 3, major diameter part is rotated for driving power wheel 2; Chassis 22 is then provided with blocking mechanism 8, and blocking mechanism 8 is for stopping the unidirectional rotation of eccentric pushing block 3 relative to chassis 22.
When dynamical axis 4 rotates towards the active direction (in Fig. 4 for conter clockwise) of one-way wheel mechanism, eccentric pushing block 3 rotates, because dynamical axis 4 bias is through the chassis 22 of power wheel 2, therefore the major diameter part of eccentric pushing block 3 is by the limit wall 21 of compressing power wheel 2, thus drive limit wall 21 to rotate, drive the reel 1 be connected with limit wall 21 to rotate further; When dynamical axis 4 rotates towards the driven direction (in Fig. 4 for cw) of one-way wheel mechanism, eccentric pushing block 3 rotates and acts on blocking mechanism 8, because blocking mechanism 8 is located at chassis 22, therefore eccentric pushing block 3 will with chassis 22 synchronous rotary, S. A. due to the two is chassis 22, the namely center shaft of power wheel 2, therefore eccentric pushing block 3 will not come in contact with the limit wall 21 of power wheel 2.
Obviously, be worth mentioning time, the implementation of aforementioned four kinds of embodiments is only preferred version, and also can there be all the other multiple specific implementations in this one-way wheel mechanism.
Such as, as shown in Figure 5,5th embodiment of the present utility model relates to a kind of withdrawing rope mechanism, 5th embodiment and aforementioned four kinds of embodiments all different, main difference part is, in the 5th embodiment of the present utility model: this one-way wheel mechanism comprises the power wheel 2 that inner ring is provided with gear grooved, be sheathed on the first gear g1 on dynamical axis 4, be in transmission connection with the first gear g1, axis fixed position is provided with the second gear g2 of slippage slot, and this second gear g2 and this power wheel 2 are in transmission connection.
In the present embodiment shown in Fig. 5, this second gear g2 is in transmission connection by the 3rd gear g3 and the tangent mode of power wheel 2 inner ring, it is worth mentioning that, in actual use, also can directly make the second gear g2 and power wheel 2 inner ring tangent, or superpose more gear, or adopt other type of drive (including but not limited to the multiple type of drive such as belt, chain), this does not affect the realization of basic fundamental effect of the present utility model.
When dynamical axis 4 rotates towards the active direction (in Fig. 5 for conter clockwise) of one-way wheel mechanism, second gear g2 engages respectively with the first gear g1, the 3rd gear g3, dynamical axis 4 drives the first gear g1, the second gear g2, the 3rd gear g3 successively, thus drives power wheel 2 to rotate.And when dynamical axis 4 rotates towards the driven direction (in Fig. 5 for cw) of one-way wheel mechanism, dynamical axis 4 drives the first gear g1 to rotate, now, by the impact of the first gear g1 driving direction, second gear g2 will along slippage slot upwards slippage, and jump out the contact range with the 3rd gear g3, thus power wheel 2 is not driven to rotate.And, particularly when dynamical axis 4 rotates towards the driven direction (in Fig. 5 for cw) of one-way wheel mechanism and power wheel 2 be in put rope form state (being left-hand revolution in Fig. 5) time, first gear g1 and the 3rd gear g3 will upwards push away to the second gear g2 simultaneously, thus makes power wheel 2 be in free state.
Select gear as the implementation of one-way wheel mechanism, there is good stability, the advantages such as processing is simple, with low cost.
Of the present utility model 6th embodiment further provides a kind of clearing apparatus, comprises any one withdrawing rope mechanism addressed in aforementioned five kinds of embodiments.
