Control process is complicated, and it is high to prepare cost, it is inconvenient for operation the drawbacks of, there is provided a kind of equipment rotating shaft operational failure passes report device automatically.
In order to solve the above technical problems, this invention takes following technique measures, a kind of equipment rotating shaft operational failure are automatic
Report device is passed, including shell 11, spring adjusting bracket 8 is fixed with the inwall of shell 11, signaling switch 6 is further fixed on, in shell
11 bottom is fixed with footstock 4；Bearing 12, the both ends point of rotary shaft 2 are respectively arranged with two relative side walls of shell 11
It is not connected with two relative bearings 12, the outside of shell 11, the rotary shaft 2 in the inside of shell 11 are stretched out in one end of rotary shaft 2
Upper device has pinwheel 1, and rotary shaft 2 hugs frictional connection with pinwheel 1, stop syringe needle 3 is provided with pinwheel 1, stop syringe needle 3 passes through
Bracing wire 5 is connected with spring adjusting rod 10, and spring adjusting rod 10 is connected by spring 7 with spring adjusting bracket 8, and spring adjusting rod 10 is controlled
Make signaling switch 6.
Take the present invention of above-mentioned measure, be a kind of monitor speed alarm of Purely mechanical, rotary shaft of the invention with
The driving shaft or posterior rotation axle of working equipment connect with one heart, and the synchronization of the driving shaft of working equipment appears in the present invention's
In rotary shaft, because rotary shaft and pinwheel hug friction law, abnormal rotating speed is caused stop pin by the correct tension of spring
Head produces displacement, and the displacement of stop syringe needle directly changes the contact or separation of signaling switch contact by bracing wire, spring adjusting rod,
So as to provide a signal output, implementing monitoring and alarm.The present invention is simple in construction, and purely mechanic form, manufacturing cost is low, implements
Easily.
Brief description of the drawings
Fig. 1 is present invention structural representation under static state, or working machine rotating shaft exception shape during present invention work
Structural representation under state：
Structural representation when Fig. 2 is present invention work under working machine rotating shaft normal condition.
The number explanation of above-mentioned accompanying drawing：Pinwheel 1, rotary shaft 2, stop syringe needle 3, footstock 4, bracing wire 5, signaling switch 6, spring
7, spring adjusting bracket 8, output line 9, spring adjusting rod 10, shell 11, bearing 12.
The present invention is described in further detail with reference to embodiment.
Embodiment
As shown in above-mentioned Fig. 1, Fig. 2, the present invention includes shell 11 and base, and spring tune is fixed with the inwall of shell 11
Frame 8 and signaling switch 6 are saved, footstock 4 is fixed with base, axle is respectively arranged with two relative side wall of outer shell of shell 11
12 are held, the both ends of rotary shaft 2 are connected with two relative bearings 12 respectively, are rotated in bearing 12, and one end of rotary shaft 2 is stretched out
The outside of shell 11 be easy to the rotating spindle of working equipment or posterior rotation axis connection, in the rotary shaft 2 of the inside of shell 11
Device has a pinwheel 1, rotary shaft 2 and pinwheel 1 hug frictional connection, one end of rotary shaft 2 and the rotating spindle of working equipment or after
Portion's rotary shaft connects with one heart, with the rotating spindle of working equipment or the rotation synchronous axial system of posterior rotation axle, the rotation of rotary shaft 2
It can be rotated simultaneously with plane gear 1, stop syringe needle 3 is provided with pinwheel 1, stop syringe needle 3 is connected by bracing wire 5 and spring adjusting rod 10
Connect, spring adjusting rod 10 is connected by spring 7 with spring adjusting bracket 8, and spring adjusting rod 10 controls signaling switch 6.Work as rotation
When axle 2 rotates with the rotating spindle of working equipment, band plane gear 1 rotates, when the stop syringe needle 3 on pinwheel 1 turns to footstock 4
Place, is intercepted, pinwheel 1 no longer rotates with rotary shaft 2 by footstock 4.Pinwheel 1 is prepared by elastomeric material, and the connection with rotary shaft 2 is in tight
Frotteurism is embraced, oil lubrication can be used to reduce frictional force.As shown in Figure 2 when pinwheel 1 turns to stop syringe needle 3 by footstock
During the state of 4 interceptions, stop syringe needle 3 pulls down the spring adjusting rod 10 hauled by spring 7 by bracing wire 5, spring adjusting rod
10 drop-down causes signaling switch 6 to be in contact separation state, is exported without signal by output line 9, this state shows
That shows is the rotating spindle uniform rotation of working equipment and meets rotation under rotating speed requirement, is a kind of normal working condition.
As shown in Figure 1 or 2, spring adjusting bracket 8 is connected with spring adjusting rod 10 by spring 7, changes spring 7 in spring
The position of adjusting bracket 8 and spring adjusting rod 10, pulling force of the spring adjusting rod 10 to stop syringe needle 3 can be changed, can also change letter
Number switch 6 action sensitivity.
The present invention has three kinds of states, first, inactive state is as shown in Figure 1；Second, normal operating conditions is as shown in Fig. 2 three are
Abnormal operation is as shown in Figure 1.
Signaling switch must not be electric under inactive state, and structure of the invention is as shown in figure 1, above-mentioned have been described repeats no more.
Normal operating conditions is such：The rotating spindle of working equipment rotates at work, drives the rotation of the present invention
Axle 2 rotates, and the rotational band plane gear 1 of rotary shaft 2 rotates, when the stop syringe needle 3 on pinwheel 1 turns to footstock 4 with pinwheel 1, quilt
Footstock 4 intercepts, and stops at footstock 4 as shown in Fig. 2 now, rotary shaft 2 continues the rotary shaft normal rotation with working equipment,
Pinwheel 1 is slack.And as stop syringe needle 3 is moved at footstock 4, bracing wire 5 be also stopped syringe needle 3 pulled down one away from
From simultaneously bracing wire 5 also pulls down spring adjusting rod 10, the contact separation of the signaling switch 6 controlled by spring adjusting rod 10, does not have
There is signal to be exported by output line 9, warning device will not be touched.Such a state is working equipment rotary shaft at the uniform velocity or met
The normal condition of egulation rotating speed.
Abnormal operation is such：The exception that rotating speed is slack-off or stops occurs when the rotating spindle of working equipment rotates
During state, the stop syringe needle 3 at footstock 4 was intercepted at originally original position is retracted by bracing wire 5, spring adjusting rod 10 also resets such as Fig. 1
Shown, now, spring adjusting rod 10 makes signaling switch 6 reset electric by 9 outside output signal of output line, Triggering circuit to be led to
Smooth alarm produces the alarm of glittering and sound, has thus reached the effect of automatic biography report.The power supply of the present invention is to start motor
Contactor output signal line, output line 9 of the invention can connect onsite alarming device, can also connect plc,
Wincc is transferred to by plc, then by wincc in alarm indication to computer.
