Technical field
The invention belongs to control technology field more particularly to a kind of pull switch warning devices.
Background technique
For the safety of production, it usually needs pull switch is installed in the two sides of belt conveyor, when an emergency situation is encountered
When, drawstring can be pulled conveniently, the normally opened contact of pull switch is closed, to make belt conveyor shut down and alarm, in reality
In production process, the phenomenon that frequently encountering pull switch malfunction and cause belt conveyor hang-up, reason is generally all
It is that the material for being generated in adhesion and conveyer belt by pull switch normally opened contact after prolonged use is fallen and pounds drawstring institute
It causes, needs to search fault point immediately once there is hang-up, it may be assumed that it is the failure as caused by which pull switch, it is right
Dozens of is shared in the pull switch of the belt conveyor line of long range, rack two sides, manpower is fully relied on and searches one by one not only
It takes time and effort, also delays production.
Summary of the invention
To solve the above problems, the present invention proposes a kind of pull switch warning device, and the device is simple and practical,
It can accurately show the accurate location for generating the pull switch of malfunction and shutdown, save maintenance time, improved work efficiency.
To achieve the goals above, the present invention uses following scheme, comprising:
It is connected to the pull switch of belt conveyor rack two sides, the pull switch is uniform along the length of the rack
It is arranged several, the pull switch includes swingable pull rod, is controlled by the pull switch normally opened contact of pull rod, and the drawstring is opened
It closes normally opened contact and connects extraction wire, connection stay cord between every pull switch adjacent two-by-two, the drawstring is connected to pull switch
Pull rod on；
The pull switch warning device further includes alarm control unit, and the alarm control unit includes several branches；
The first branch includes the first pull switch normally opened contact corresponding with the first pull switch, first pull switch
Normally opened contact is concatenated with the first intermediate relay, and the first intermediate relay simultaneously connects the first alarm lamp；
Second branch includes the second pull switch normally opened contact corresponding with the second pull switch, second pull switch
Normally opened contact is concatenated with the second intermediate relay, and the second intermediate relay simultaneously connects the second alarm lamp；
N-th branch includes that the n-th pull switch normally opened contact corresponding with the n-th pull switch, n-th pull switch are normally opened
Contact is concatenated with the n-th intermediate relay, and the n-th intermediate relay simultaneously connects the n-th alarm lamp；
The first intermediate relay normally opened contact, the second intermediate relay open contact, the n-th intermediate relay normally opened contact
It mutually and after connecting is concatenated with control relay, control relay normally closed contact accesses PLC controller；
The first branch, second branch, the n-th branch mutually and even after one end access the pole power supply L, the other end access electricity
The source pole N；
The first intermediate relay normally opened contact, the second intermediate relay open contact, the n-th intermediate relay normally opened contact
The other end access the pole power supply L, it is described control relay the other end access the pole power supply N.
The pole the power supply L is also connected with fuse.
A kind of pull switch warning device of the present invention, the device is simple and practical, can accurately show the drawstring for generating malfunction
The accurate location of switch and shutdown, have saved maintenance time, have improved work efficiency.
