Structural representation under working machine rotating shaft normal condition when Fig. 2 is utility model works.
The sequence 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.
Below in conjunction with embodiment, this utility model is described in further detail.
Detailed description of the invention
As shown in above-mentioned Fig. 1, Fig. 2, this utility model includes shell 11 and base, is fixed with bullet on the inwall of shell 11
Spring adjusting bracket 8 and signaling switch 6, be fixed with footstock 4 on base, and two relative side wall of outer shell of shell 11 are respectively provided with
Having bearing 12, the two ends of rotary shaft 2 connect with two relative bearings 12 respectively, rotate, one end of rotary shaft 2 in bearing 12
Stretch out the outside of shell 11 and be easy to the rotating spindle with work equipment or posterior rotation axle is connected, the rotary shaft inside shell 11
On 2, device has a pinwheel 1, and rotary shaft 2 and pinwheel 1 hug frictional connection, one end of rotary shaft 2 and the rotating spindle of work equipment or
Posterior rotation axle connects with one heart, with rotating spindle or the rotation synchronous axial system of posterior rotation axle of work equipment, turning of rotary shaft 2
The dynamic band plane gear 1 of energy simultaneously rotates, and pinwheel 1 is provided with stop syringe needle 3, and stop syringe needle 3 is by bracing wire 5 and spring adjusting rod 10
Connecting, spring adjusting rod 10 is connected with spring adjusting bracket 8 by spring 7, and spring adjusting rod 10 controls signaling switch 6.When turning
When moving axis 2 rotates with the rotating spindle of work equipment, band plane gear 1 rotates, when the stop syringe needle 3 on pinwheel 1 turns to footstock 4
Place, is intercepted by footstock 4, and pinwheel 1 no longer rotates with rotary shaft 2.Pinwheel 1 is prepared by elastomeric material, and the connection with rotary shaft 2 is in tightly
Embrace Frotteurism, oil lubrication can be used for reducing frictional force.Stop syringe needle 3 is turned to by footstock as shown in Figure 2 when pinwheel 1
During the state that 4 intercept, the spring adjusting rod 10 that stop syringe needle 3 is hauled by spring 7 by bracing wire 5 pulls down, spring adjusting rod
10 drop-down make signaling switch 6 be in contact separation state, do not have signal to pass through output line 9 and export, this state shows
Show is the rotating spindle uniform rotation of work equipment and the rotation under meeting rotation speed requirements, is a kind of normal duty.
As shown in Figure 1 or 2, spring adjusting bracket 8 is connected by spring 7 with spring adjusting rod 10, changes spring 7 at spring
Adjusting bracket 8 and the position of spring adjusting rod 10, it is possible to change the spring adjusting rod 10 pulling force to stop syringe needle 3, also can change letter
Number switch 6 action sensitivity.
This utility model has three kinds of states, one be resting state as shown in Figure 1；Two be normal operating conditions as in figure 2 it is shown,
Three be abnormal operation as shown in Figure 1.
Under resting state signaling switch must not electricity, structure of the present utility model as it is shown in figure 1, above-mentioned have been described the most superfluous
State.
Normal operating conditions is such that the rotating spindle of work equipment and operationally rotates, and drives of the present utility model
Rotary shaft 2 rotates, and rotary shaft 2 rotational band plane gear 1 rotates, when the stop syringe needle 3 on pinwheel 1 turns to footstock 4 with pinwheel 1
Time, being intercepted by footstock 4, stop at footstock 4 as in figure 2 it is shown, now, it is normal that rotary shaft 2 continues the rotary shaft with work equipment
Rotating, pinwheel 1 is slack.And along with stop syringe needle 3 is moved at footstock 4, bracing wire 5 is also stopped syringe needle 3 and has pulled down one
Individual distance, bracing wire 5 also pulls down spring adjusting rod 10 simultaneously, spring adjusting rod 10 contact of the signaling switch 6 controlled is divided
From, do not have signal to pass through output line 9 and export, alarm device will not be touched.This kind of state be work equipment rotary shaft at the uniform velocity
Or meet the normal condition of regulation rotating speed.
Abnormal operation is such that, when the rotating spindle of work equipment rotates, the exception that rotating speed is slack-off or stops occurs
During state, being originally intercepted at the stop syringe needle 3 at footstock 4 and retracted in situ by bracing wire 5, spring adjusting rod 10 also resets such as Fig. 1
Shown in, now, spring adjusting rod 10 makes signaling switch 6 reset electric by the outside output signal of output line 9, and Triggering circuit leads to
Smooth alarm produces glittering and sound warning, has thus reached the effect of automatic biography report.Power supply of the present utility model is to start
The signal line of the catalyst output of motor, output line 9 of the present utility model can connect onsite alarming device, it is also possible to even
Meet plc, be transferred to wincc by plc, then by wincc in alarm indicator to computer.
