Fig. 3 is the circuit diagram of the utility model application state.
Specific embodiment
As shown in Figs. 1-2, belt feeder dragline emergency stop switches provided by the utility model act warning device, have shell
Body, shell include the sequentially connected first part 1-1 in front and back, second part 1-2 and Part III 1-3.Enclosure interior setting
There are transverse movement axle unit, contact switch S, fixing axle 2, transverse movement axle unit includes in first part, second part
The first kinematic axis 3-1 in portion, and be arranged inside Part III, the second motion shaft 3- being connected with the first movement shaft rear end
2, the first kinematic axis front end extends outwardly along first part, and connect with the drawstring latch closure 4 of hull outside, and is located at the
It is outer on the shaft part of the first kinematic axis inside a part to be cased with preceding reset spring 5-1.
The contact switch includes the auxiliary contact 6 that the left and right sides is arranged in, and keeps a pair of auxiliary when contact switch uses
Help the working condition that contact is normally opened, a pair of of auxiliary contact are normally closed.Auxiliary contact use yellow gold material, and electric conductivity is good,
The two pairs of auxiliary contact in present apparatus contact switch setting left and right can select one pair of them touching according to the needs of different embodiments
Point is as in the normally-closed contact access electric power loop of contact switch.Second motion shaft rear end is connected with contact actuating rod 7, and contact is made
With effect contact 7-1 corresponding with the auxiliary contact of contact switch is provided on bar, fixing axle is fixed on Part III rear end,
It is outer in fixing axle to be cased with rear reset spring 5-2, one end of rear reset spring and contact actuating rod fixed connection, wherein to make contact
In the initial state with the effect contact on bar, state is kept in contact with the auxiliary contact of contact switch side.Hull outside is also
It is provided with control unit, the alarm lamp 8 of DC24V red LED lamp is provided in control unit, has 24V's inside control unit
