For the first axis hole 311 that transmission shaft 3 passes through, the transmission shaft 3 can be installed in relative rotation in first axis hole 311,
That is, the anti-drop cover 31 will not be rotated with the rotation of the transmission shaft 3.The anti-drop cover 31 is further opened with for installing two institutes
The cavity of rotation stop plate 32 is stated, and the both ends of the cavity pass through the side wall of the anti-drop cover 31 to form two one-to-one openings
312.The side wall of the anti-drop cover 31 axially extends and can accommodate respective side I-beam wheel retaining wall with corresponding end wall composition one
43 mating groove 313.The anti-drop cover 31 is further opened with to be made with 32 matched notch 314 of any rotation stop plate, the notch 314
The rotation stop plate 32 is obtained to match with corresponding I-beam wheel 40.
Any rotation stop plate 32 opposite can be slidably mounted in the cavity of the anti-drop cover 31, and its both ends is protruded respectively
In corresponding opening 312.One end that the rotation stop plate 32 closes on the notch 314 is convexly equipped with matched with the notch 314
Bending head 321, the bending head 321 is in the recess 431 for the retaining wall 43 that the notch 314 is caught in corresponding I-beam wheel 40.Institute
It states the one end of rotation stop plate 32 far from the notch 314 and offers mounting hole 322.
One end of the traverse shaft 33 is installed in the mounting hole 322, lower section of the other end by corresponding I-beam wheel 40
Stretch into afterwards in the limiting slot 113 of the self-locking spring cup assembly, limitation traverse shaft 33 in the limiting slot 113 radially
Movement, to which the rotation stop plate 32 that is fixedly connected with traverse shaft 33 of limitation is relative to the movement of anti-drop cover 31.It is appreciated that described stop
Flap 32 is further opened with the sliding groove 323 passed through for transmission shaft 3, and the sliding groove 323 opens up direction and the limiting slot 113
To open up direction consistent, be vertical direction in the present embodiment.One steel wire rope, 5 one end connects one end of airing rod 8, the other end
Around being wound on the winding axis 42 of the I-beam wheel 40 after the traverse shaft 33.
The conducting wire axle sleeve 34 is set on the outer wall of the traverse shaft 33, long-term to avoid traverse shaft 33 and steel wire rope 5
It is in direct contact friction and leads to wear traverse shaft 33, be conducive to extend service life.
The resetting spring 35 is installed between the rotation stop plate 32 and the anti-drop cover 31, for when airing rod 8 is hampered
Make rotation stop plate 32 fall to its bending head 321 to snap onto in the recess 431 of corresponding I-beam wheel 40, to realize I-beam wheel 40 from
Lock.In the present embodiment, the both sides of the rotation stop plate 32 have protruded out a crushing block 324 respectively, and 35 one end of a resetting spring is held in
On the crushing block 324, the other end is mutually fixedly connected by the holding screw 36 with 31 top of the anti-drop cover.
Embodiment 2
Fig. 6-9 is please referred to, invention additionally discloses a kind of hand-operated device 101, including shell 2, transmission shaft 3, rocking handle 4 and is hampered
Self-locking mechanism, the self-locking mechanism that is hampered is consistent with the self-locking mechanism that is hampered described in above-described embodiment 1, in the present embodiment no longer
It repeats one by one.
The shell 2 has an accommodating cavity for installing the self-locking mechanism that is hampered.The self-locking mechanism installation that is hampered
In in the accommodating cavity of the shell 2.The spring cup 11 and the anti-drop cover 31 are fixedly installed in the shell 2.
3 one end of the transmission shaft sequentially pass through the self-locking spring cup assembly, an I-beam wheel 40, be hampered from lock set 30,
After another I-beam wheel 40 with it is described after self-locking spring cup assembly 10 rotor 13 it is coaxially connected, the other end pass through the shell 2 with
The rocking handle 4 is connected.User is by rocking handle 4 described in rocking-turn, to drive the transmission shaft 3 to rotate, and then drives two turns
Son 13 rotates synchronously, and two rotors 13 rotate and then drive the rotation of two corresponding I-beam wheels 40.
It is under normal circumstances, another since 5 one end of steel wire rope is wrapped in around conducting wire axle sleeve 34 in I-beam wheel 40 when work
End connection airing rod 8, by airing rod 8, gravity itself is acted on, and steel wire rope 5 is to stretch stress, at this point, as shown in fig. 7, steel wire rope
5 by 33 applied force F of the traverse shaft to the 32 applied force F of rotation stop plate of connection fixed thereto, when design, need to ensure multiple
The elastic force of position spring 35 is less than the gravity of single airing rod 8, then since power F is more than the elastic force of resetting spring 35, rotation stop plate 32 exists
It is moved up under the action of power F, traverse shaft 33 stops after being moved upward to its top in limiting slot 113, to which limitation stops
Flap 32 continues to rise, at this point, the bending head 321 at 32 top of rotation stop plate is detached with 40 bumps side block wall 43 of corresponding I-beam wheel, this
When, I-beam wheel 40 is not limited by rotation stop plate 32, can be rotated with the rotation of rocking handle 4.Above to the self-locking mechanism side that is hampered
The principle that runs under normal circumstances of I-beam wheel 40 be illustrated, the I-beam wheel 40 for the self-locking mechanism other side that is hampered is also base
In aforementioned same principle.
When airing rod 8 is hampered, as shown in figure 8, at this point, the steel wire rope 5 of connection airing rod 8 will not be in by 8 gravity of airing rod
Relaxed state, then steel wire rope 5 can not 33 applied force of guide spool, at this point, as shown in figure 5, rotation stop plate 32 is in resetting spring 35
It is fallen under effect in notch 314 and (need to ensure that the elastic force of resetting spring 35 is more than the gravity of rotation stop plate 32 when design), at this point, only
The bending head 321 at 32 top of flap is engaged with the recess 431 of the concave-convex side of I-beam wheel 40, and then it is opposite only to limit the I-beam wheel 40
Flap 32 rotates, and completes the self-locking that is hampered.
Structure of the invention can be also used for preventing reverse-winding when draining of steel wire rope 5, at this point, need to be in steel wire rope 5
A connection piece 6 is installed at the preset distance of end, as shown in figure 9, when steel wire rope 5 drains soon, the company of 5 one end of steel wire rope
Fitting 6 is touched with pulley base 7, since connector 6 can not be continued shake hand-operated device 101 and put steel wire rope 5, then slided by pulley base 7
The steel wire rope 5 of wheel seat 7 to 101 this section of hand-operated device will be hampered for the state of not stressing, one when being hampered with the airing rod 8 described in the last period
Sample, at this point, steel wire rope 5 can not 33 applied force of guide spool, rotation stop plate 32 falls to notch 314 under the action of resetting spring 35
Interior, the bending head 321 at 32 top of rotation stop plate is engaged with the recess 431 of the concave-convex side of I-beam wheel 40, at this point, I-beam wheel 40 is locked,
It can not be rotated further, to protect steel wire rope 5 not continue to wind, and be finally reached steel wire rope 5 and will not occur because of being drained
The purpose of reverse-winding.
To sum up, be hampered self-locking mechanism and hand-operated device 101 of the present invention, can effectively prevent airing rod 8 in lifting process
In there is airing rod 8 and be hampered to cause 5 tangled up and knotted problem of steel wire rope, meanwhile, can also prevent steel wire rope 5 from reversely twining with this configuration
Around, avoid the occurrence of repeatedly folding steel wire rope 5, prolong the service life.
As described above, the present invention can be realized preferably.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, according to
According to the present invention technical spirit, within the spirit and principles in the present invention, to made by above example it is any it is simple modification,
Equivalent replacement and improvement etc., still fall within the protection domain of technical solution of the present invention.
