Described push rod afterbody is formed with the diameter locating ring more than push rod, and described perforation is that shoulder hole is to permit
Permitted described locating ring to be embedded.
A kind of mud scraper with described shear pin sprocket wheel.
Prior art is compared, and the beneficial effects of the utility model are:
Shear pin sprocket wheel of the present utility model, when, after apparatus overload, first shear pin ruptures, and so cuts off
Power exports, it is to avoid electrical equipment and the damage of plant equipment, then under the effect of motor, and sprocket hub and sprocket wheel
Relative displacement occurs, and the head of the push rod being contained in by afterbody in sprocket wheel circular groove is from the other end of sprocket hub
Portion highlights, and ledge continues to rotate to reach sensor with sprocket hub, at limit switch, touches spacing opening
Closing, send alarm signal, cut off driving motor power simultaneously, power-off is timely, simple and reliable.
Accompanying drawing explanation
Fig. 1 show the structural representation of the shear pin sprocket wheel of band warning function of the present utility model；
Fig. 2 show the cross section structure schematic diagram of Shear Cut Pin sprocket wheel of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that
Specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, 2, the shear pin sprocket wheel of band warning function of the present utility model includes stainless steel chain
Wheel hub 1, non-metallic material sprocket wheel 2, push rod 4, shear pin 3 and the biography being correspondingly arranged with described push rod
Sensor (not shown), described shear pin two ends are embedded accordingly at described sprocket hub 1 and sprocket wheel 2
On, described sprocket hub is provided with the perforation 11 that described push rod head can be allowed to pass, described sprocket wheel
On be formed with the circular groove 21 that the push rod afterbody described in permission slides wherein, described arc groove
Bottom surface is progressively increased.Described non-metallic material can use the current materials such as fiberglass, is not repeated herein.Its
In, the head of described push rod refers to point to hub side, and the afterbody of push rod or rear portion refer to point to sprocket wheel side.
Specifically, described sprocket hub includes side flange, and the described integral part of boss of side flange,
Described sprocket wheel be centrally formed with conical through-hole to be set on described boss and axially to be positioned by jump ring 6.
The hole, location of described perforation and shear pin is respectively formed on described side flange, simultaneously shape on sprocket wheel
Becoming to have shear pin to position hole 22, shear pin is embedded in described hole 22, shear pin location by card by guide 5.
Shear pin sprocket wheel of the present utility model, sprocket hub is rotated by shear pin band movable sprocket under normal circumstances,
Now push rod afterbody is positioned at the minimum point of circular groove, and push rod head is hidden in described perforation, works as shearing
When pin stress reaches setting value, shear pin ruptures, and at this moment sprocket wheel stops, and wheel hub is rotated further, both phases
Make the push rod head being placed in the circular groove of sprocket wheel highlight sprocket hub plane to rotating, touch limit switch,
Realize warning shutdown effect.
The especially suitable chain mud scraper that is installed on of shear pin sprocket wheel of the present utility model drives on output shaft, reaches
In time, reliably, be effectively protected mechanically and electrically machine equipment, it is ensured that equipment and process technique properly functioning,
Because its part is few, having simple in construction low cost of manufacture, corresponding equipment investment and later stage operating maintenance etc. take
By the advantage reduced.
Wherein, described sensor is can the contact corresponding with described push rod head or magnetic driven sensing
Device, as being fixedly installed on sprocket wheel side can be with the limit switch ejecting state push rod head phase separation.Or institute
The sensor stated is and the reflective or emission sensor of the push rod head phase separation ejecting state.That is, any
Push rod can be sensed eject the sensor of action or state and all can be applicable to this, sensor-based signal, it is achieved
Sending alarm signal and the effect cut off the electricity supply, power-off is timely, simple and reliable, is effectively improved human-computer interaction.
Preferably, described push rod afterbody is formed with the diameter locating ring more than push rod, and described perforation is rank
Ladder hole is embedded with the locating ring described in allowing.When it is squeezed in the shoulder hole of sprocket hub, prevent top
The push rod that bar is surprisingly deviate from from sprocket hub and caused is lost, and damages and disabler.Wherein, shoulder hole or
Between perforation and push rod, there is certain frictional force, to ensure that only ability is the most active when being held by circular groove
Making, it is to avoid misoperation, the rear end of simultaneously, preferably described shoulder hole and locating ring have inlay card positioning action,
Unexpected to avoid push rod to return generation.
Preferably, the central angle of described circular groove is more than 30 degree, less than or equal to 60 ° so that it is lead
Journey angle is sufficiently large, it is to avoid self-locking, simultaneously for improving the push rod mobile effect in circular groove, described
