It is disconnected with earth clip playback conductive plate.
What technical problem to be solved in the utility model can also be realized by technical solution below, described leads
Electric part is power spring.
What technical problem to be solved in the utility model can also be realized by technical solution below, described two
Position three-way valve is hand rotary valve, and the contact switch is on the handle of hand rotary valve.
Compared with prior art, the utility model is by setting cylinder actuating mechanism and electrostatic grounding warning device, the two knot
The alarm monitoring realized whether playback to autostairs is closed, by setting earth clip playback conductive plate, contact switch and ground cable, structure
At warning circuit after the completion of autostairs works, when tank car being avoided to sail out of with autostairs pull and cause autostairs and tank car by
Damage, structure is simple, application method, whether effectively monitoring autostairs playback.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural schematic diagram of two position three-way valve;
Fig. 3 is the main view of Fig. 2.
Specific embodiment
Referring to the drawings, the specific technical solution of the utility model is further described, in order to those skilled in the art
Member is further understood that the utility model, without constituting the limitation to its right.
Referring to Fig.1-3, a kind of autostairs playback-electrostatic grounding combines warning device, the gas including control autostairs playback
Electrostatic grounding warning device whether cylinder executing agency and monitoring autostairs playback;
The cylinder actuating mechanism is equipped with the driving cylinder 3 that driving autostairs work and resetted, and drives two of cylinder 3
Chamber is connected by two position three-way valve 2 with gas source, and the two position three-way valve 2 is hand rotary valve;
The electrostatic grounding warning device includes alarm 1, and static grounding clamp 5, two-position three way are connected on alarm 1
Earth clip playback conductive plate 4 on the shell of valve 2 equipped with ground cable 9 and for clamping static grounding clamp 5, earth clip playback are led
Battery plate 4 is equipped with the contact switch to connect with ground cable 9, and the contact switch is on the handle of hand rotary valve;
The contact switch includes the conductive contact blade 8 being connected with ground cable 9 and playbacks on conductive plate 4 mounted in earth clip
Conduct piece 6, be equipped with to rotate synchronously with two position three-way valve 2 between conduct piece 6 and conductive contact blade 8 and realize conduct piece 6 and conductive touch
The conductive contact 7 of 8 on-off of piece, conductive contact 7 is on two position three-way valve 2;
When two position three-way valve 2 goes to closed position, conductive contact 7 connects conduct piece 6 and conductive contact blade 8, ground line
