Description
Technical field
The present invention relates to belt conveyor protection switch field, more particularly to a kind of mining intrinsic safety type two-stage sideslip to open
Close.
Background technology
Two-stage deviation switch is the product for detecting belt of belt conveyor running deviation value, is being run for conveyer belt
Automatic alarm and a kind of safety guard shut down are played in the case of partially.
The operation principle of two-stage deviation switch is：When conveyer belt emerged in operation sideslip, conveyer belt touching switch edger roll
And edger roll is deflected, when edger roll deflection angle reaches 1 grade of switch angle, switch sends alarm signal.When belt deflection is tight
Weight, when reaching 2 grades of switch angles, switch sends stopping signal, realizes belt deflection failure autostop.When deviation fault is arranged
After removing, when sealing-tape machine runs well, switch edger roll can automatically reset, and return to original state.
There are the following problems for most two-stage deviation switchs in the market：First, due to unreasonable structure, two-stage sideslip
Volume of switch is relatively large；Second, most two-stage deviation switchs do not have early warning, warning function.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided it is a kind of reasonable in design compact,
A kind of mining intrinsic safety type two-stage deviation switch with early warning and warning function.
To realize that the present invention provides following technical scheme：A kind of mining intrinsic safety type two-stage deviation switch, including housing,
The case top is provided with protuberance, and protuberance inner chamber middle part is provided with push rod, spring, push rod are cased with the push rod
Stretch into housing；Rocker assembly is provided with above the push rod, the rocker assembly includes：Sideslip edger roll, connecting rod and ball seat, it is described
Ball seat is contacted with push rod, and connecting rod is provided with the top of ball seat, and connection boom end is provided with sideslip edger roll；The housing cavity top center
Position is provided with two microswitches, and the microswitch is located at the lower section of push rod, setting straggly above and below two microswitches, two
Microswitch is connected with two sensors respectively, and the centerline of the housing and rocker assembly is on same straight line.
Preferably, the housing is provided with cover plate, the cover plate is provided with nameplate, alarm and alarm lamp, the report
Alert device is connected with two sensors respectively with alarm lamp.
Preferably, sealing gasket is provided between the housing and cover plate.
Preferably, housing bottom is additionally provided with loudspeaker nozzle.
Preferably, housing sidewall bottom, which is provided with, is fixedly connected with piece.
Usefulness of the present invention：First, the centerline of housing and rocker assembly on same straight line, run by whole two-stage
The structure of partial switch is compacter；Second, two microswitches are set, and alarm and alarm lamp are set, first fine motion
It is bright that switch is touched Times warning lamp；Second microswitch be touched alarm device sound, while belt feeder stop transmission, early warning and
Warning function is more effective.
