Description
Technical field
The present invention relates to a kind of non-return device, and in particular to a kind of vertical shaft centrifugal non-return device and check method, it is special
Shi Yongyu not vertical shaft type operating parts.
Background technology
In mechanical engineering field, inverted in order to avoid operating parts when shutting down or meeting fortuitous event jerk, it is desirable to
Non-return device is installed on parts, so not only contributes to protection equipment, and also ensure that the life security of staff.It is existing
Some non-return device species are various, common are belt holdback, roller type brake etc., served in parts operation process
Anti-reverse effect, its deficiency are there is the problems such as noise is big, quick abrasion, short service life, and are seldom applied to vertical shaft
Formula operates parts.
The content of the invention
In order to overcome the deficiencies in the prior art above, it is an object of the invention to provide one kind to be applied to vertical shaft type conveyer
The vertical shaft centrifugal non-return device and check method of part, there is noiseless, abrasion is small, departure rotary speed is adjustable (or relatively low), makes
With the good characteristic of long lifespan, convenient disassembly, check effect.
To achieve these goals, the technical solution adopted by the present invention is:
A kind of vertical shaft centrifugal non-return device, including body 1, input shaft 9 is vertical and is fixed on body 1 without axial displacement
Center, ratchet 2 are arranged on the end face of body 1 and form fixation kit;On the ratchet 2, the border of input shaft 9 be provided with disk frame
6, ratchet 7 is evenly distributed with the circumference of the disk frame 6, and each detent positions corresponding position is provided with small ratchet 5, small ratchet
5 gear teeth are relative with ratchet 7;The ratchet 7 also is provided with the gear teeth on the end face relative with small ratchet 5, and bearing pin 8 is from disk frame
6 inner sides sequentially pass through eccentric position, the centroid position of small ratchet 5 of ratchet 7, and disk frame 6, which is connected on input shaft 9, forms fortune
Dynamic component.
The ratchet 7 is meshed by axial movement of the centrifugal force along bearing pin 8 with small ratchet 5.
The ratchet 2 is arranged on the end face of body 1 with screw 3 and pad 4.
The disk frame 6 is connected on input shaft 9 by key 10.
The check method of vertical shaft centrifugal non-return device described above, ratchet 2 is connected with body 1 is used as fixture, spine
Pawl 7 is used as movement parts;During original state, ratchet 7 is freely sagging to be contacted with ratchet 2 by Action of Gravity Field;The rotating speed of input shaft 9 rises to
During a certain particular value, ratchet 7 is kept the axial movement along bearing pin 8 by centrifugal action, and is meshed with the gear teeth of small ratchet 5,
It is kept completely separate with ratchet 2, non-return device is stable, smoothly operates;Jerk, input shaft 9 occurs when shutting down or meeting special circumstances
Rotating speed is slowed down gradually when stopping or reversion occur, and the ratchet 7 in engagement is fallen by Action of Gravity Field, along ratchet 2
The direction of the gear teeth is slided, and is finally caught in the teeth groove of ratchet 2 and is stopped, and prevents from inverting.
The key technology of the present invention is, small ratchet 5 is additionally arranged at each ratchet 7;The small ratchet 5 is equably fixed
On the circumference of disk frame 6, the small gear teeth of ratchet 5 are relative with ratchet 7;The ratchet 7 is set on the end face relative with small ratchet 5
There are the gear teeth.When ratchet 7 is by centrifugal action, ratchet 7 keeps the axial movement along bearing pin 8 and is meshed with the small gear teeth of ratchet 5,
It is kept completely separate with ratchet 2.The technology need not use spring structure, extend the service life of centrifugal non-return device.
Brief description of the drawings

Fig. 2 is a kind of vertical shaft non-return device top view cross section structural representation of the present invention.
In figure, 1. bodies, 2. ratchets, 3. screws, 4. pads, 5. small ratchets, 6. disk frames, 7. ratchets, 8. bearing pins, 9.
Input shaft, 10. keys.
Embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
Referring to Fig. 1, Fig. 2, body 1 fixed first and input shaft 9, keep input shaft 9 vertical and without axial displacement.Connect down
Come, the screw 3 of ratchet 2, pad 4 are fixed on the end face of body 1, form fixation kit.Multiple ratchets 7 and small ratchet 5 are uniform
It is distributed on the circumference of disk frame 6, bearing pin 8 sequentially passes through the eccentric position of ratchet 7, small ratchet 5 from disk frame 6 inner side
Centroid position, ensure that ratchet 7 can freely swing, it is freely sagging when not by external force;After the component of disk frame 6 assembles, with
Input shaft 9 is fixed with one by key 10, forms moving parts.Under original state, ratchet 7 is sagging to be in contact with ratchet 2;Work as check
After device rotary speed rises to a certain particular value, ratchet 7 completely disengages with ratchet 2, non-return device noiseless, collisionless, smoothly transports
Turn.
