Weary protective cover has certain risk.So to exposed turn of the whole in device on controllable rotating motor and speed-changing gear box
Dynamic part should effectively be protected, and be damaged so as to prevent personnel from touching rotary part or rotary part depigmentation.
Utility model content
To solve the above problems, the utility model provides a kind of guard rail for rotation speed standard device rotary part
Grid, protective cover can be played a part of, prevent personnel from touching rotary part or rotary part depigmentation and damaging, be easy to safeguard
Personnel's installation, remove and change.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of protection barrier for rotation speed standard device rotary part, the protection barrier are designed using cover type, including the
One barrier, the second barrier and bouncing plate, first barrier include two arc barriers and band mounting hole mounted thereto
The first disk, second barrier include an arc barrier and mounted thereto one with raised connector second circle
Disk, first barrier, the second barrier are connected by mounting hole and raised connector, first disk and the second disk
Outside is mounted on a connecting rod with installing tache.Auxiliary pin of the length for its 2/3 length is equipped with the inside of every arc barrier, can
Stagger；The arc barrier lower end is provided with aduncate stay hook, and the bouncing plate is a v-shaped structure, and its both ends is symmetrically opened
Provided with the through hole being engaged with the installing tache.
Preferably, first disk, arc barrier, the second disk, connecting rod use aluminium alloy.
Preferably, the raised connector insertion mounting hole forms moving axis.
Preferably, two sides of bouncing plate are connected by installing tache and through hole with two connecting rods respectively, clutch bouncing plate, and two
The opening increase of barrier distal foot.
The utility model has the advantages that：
1. protection barrier is combined by several bonding jumpers, rotating part will not all be covered, regarded so not interfering with
Line and normal operating.
2. the design of class clamp type is easy to dismount at any time, while ensureing safe, sensor installation, dismounting are not interfered with
Or the inspection and maintenance of equipment.
3. the design of its bell shape of protection barrier ensure that smooth no sharp corners, new dangerous matter sources will not be turned into.
4. there is enough spaces between protective cover barrier body and rotary part, it can prevent rotary part from touching guard rail
Grid body, avoid hindering rotary part operating, or cause to protect barrier body or rotary part damage.
5. protection barrier can be fixedly mounted on controllable rotating motor and speed-changing gear box, will not be because of motor and gearbox
Vibration and produce relative displacement.
6. using aluminium alloy manufacture, have certain strength and stiffness, can effectively avoid because produce moderate finite deformation and with activity
Part is touched.

Embodiment
In order that the purpose of this utility model and advantage are more clearly understood, the utility model is entered with reference to embodiments
Row is further described.It should be appreciated that specific embodiment described herein is only to explain the utility model, and do not have to
In restriction the utility model.
As described in Fig. 1-Fig. 4, the utility model embodiment provides a kind of for the anti-of rotation speed standard device rotary part
Guardrail grid, the protection barrier are designed using cover type, and the protection barrier is designed using cover type, including the first barrier 1, the second barrier 2
With bouncing plate 7, first barrier 1 includes two arc barriers and the first disk mounted thereto with mounting hole 5, institute
Stating the second barrier 2 includes an arc barrier and mounted thereto one the second disk with raised connector 8, and described first
Barrier 1, the second barrier 2 are connected by mounting hole 5 and raised connector 8, on the outside of first disk and the second disk
One connecting rod 9 with installing tache 10 is installed.Auxiliary pin 3 of the length for its 2/3 length is equipped with the inside of every arc barrier, can be wrong
Open；The arc barrier lower end is provided with aduncate stay hook 4, and the bouncing plate 7 is a v-shaped structure, and its both ends is symmetrically opened
Provided with the through hole 6 being engaged with the installing tache 10, first disk, arc barrier, the second disk, connecting rod use aluminium
Alloy, the raised connector 8 insert mounting hole 5 and form moving axis, and two sides of bouncing plate 7 pass through installing tache 10 and through hole respectively
6 are connected with two connecting rods, clutch bouncing plate, the opening increase of two barrier distal foots.
As shown in figure 5, this specific implementation, in use, clutching the junction of two bending sections, the opening of two barrier distal foots increases
Greatly, after the first barrier 1 and the second barrier 2 then being adjusted into corresponding position, i.e., the angle of two barriers is 120 degree；Finally
Stay hook is clipped in the groove of rotation speed standard device, loosens the junction of two bending sections.On the inside of every arc barrier
Auxiliary pin provided with a length for its 2/3 length, can stagger, thus can be changed into 6 pin by 3 jiaos of integral protection barrier.Rotating speed fluted disc compared with
When big, 3 jiaos can play protective action, protect the space of barrier larger, be easily installed removal sensor, assembling and disassembling sensor
When can not remove protection barrier；When fluted disc is smaller, if fluted disc depigmentation in rotation, may fly out between space, so by 3
Pin is changed into 6 jiaos of spaces that can reduce protection barrier, prevents fluted disc from flying out.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
