Embodiment 2
Refering to Fig. 1 to Fig. 6, for a kind of another anti-static device, embodiment 2 in place of the difference of embodiment 1 with being：Also
Including motor 10 and it is fixed in the rotating shaft of motor 10 and screwed drive screw 11, the free end of vertical rod 9 are provided with band
Screw thread and the locating ring 12 engaged with drive screw 11；The free end of drive screw 11 is fixed on one and is arranged on ladder guardrail 14
On bearing 15 on.Drive screw 11 engages with locating ring 12 so that in 10 axis of rotation of motor, the band of drive screw 11
Dynamic locating ring 12 is promoted or retreated, so as to realize the elongation of retracting cylinder 3 or contraction；The setting of bearing 15, it can will drive spiral shell
The end of bar 11 is positioned.
Also include rotating forward loop 17, reversion loop 18 and two and drive a pass button 16；Two drive a pass button 16 by dialling
Move and switch selection access and rotate forward loop 17 or access reversion loop 18 or do not access any loop；Rotate forward loop 17, invert back
Road 18 is connected with motor 10 respectively；Two, which drive a pass button 16, is arranged on sleeve 1
In the present embodiment, the start and stop of motor 10, using circuit loop of the prior art and two open the switch of a pass by
Button, three shift knobs are integrated on a button, and one closes button positioned at centre, and two, which drive button, is located at both ends, and two drive button point
Forward direction, reverse directions are not represented.When button is allocated to when driving button of forward direction, the access of motor 10 rotates forward loop 17, from
And rotated forward, drive retracting cylinder 3 to be extended；When button is allocated to when driving button of reverse directions, the access of motor 10 inverts back
Road 18, so as to be inverted, retracting cylinder 3 is driven to be shunk；When button, which is allocated to the one of centre, closes button, circuit disconnects, from
And the expanding-contracting action of retracting cylinder 3 is stopped.
Refering to Fig. 7, in figure：KM1/KM2, it is contactor auxiliary node, as long as contactor band electrical excitation, normally opened node just close
Close, normally closed node just disconnects；KM3/KM4, it is the normally opened node of contactor；KM5/KM6, it is the normally closed node of contactor；KM7/KM8、
KM9/KM10, it is represented as contactor；M is motor 10；FU1/FU2, it is fuse；FR, it is electrothermal relay；SB1, press for stopping
Button；SB2, it is to rotate forward button；SB3, it is reversion button；KT, it is the time relay and its auxiliary node；QS, motor power are spaced apart；
L1/L2/L3, be three phase mains in each phase.Two to drive a pass button be prior art construction in the present embodiment, using it is dual mutually
Lock, and two types contactor, the normally closed auxiliary contact of two kinds of contactors are serially connected in side hydraulic circuit, safe ready,
The generation of short circuit is avoided, while uses a time relay, as long as setting a time definite value, when the delay of relay definite value reaches
After arriving, loop delay disconnected node will disconnect automatically, and motor control loop disconnects, so as to realize automatic hold function.
The present embodiment is related to two courses of work for driving a pass button：After motor power QS closes, right side control loop connects
Enter the two-phase in three phase mains, so as to the loop of the leftmost side, after pressing SB2 and rotating forward button, SB1, SB3 and KM5 in loop
Node, KM9 contactors, KT delay disconnected nodes loop are connected, and motor, which is realized, to be rotated forward, the KM3 auxiliary node in parallel with SB2 buttons
A self-holding function is played, after loop is switched on, KM9 contactors band electrical excitation, its auxiliary node will close, although
After SB2 disconnects, rotate forward loop and still connect, rotate certain time, after reaching the time definite value that the time relay is set, KT's
Delay disconnected node will be delayed disconnections, and loop is rotated forward so as to cut off, because the relation of interlocking, when rotating forward loop connection
Wait, reversion loop disconnects, and process is same to rotate forward loop.Equivalent to one fuse of FU1 fuses, when electric current is excessive in loop
Time will fuse, cut-off loop, and FR is a motor overheating protection, when motor long time running causes motor overheating, FR's
Node can also disconnect, cut-off loop, prevent motor overheating and burn out.It is some contactors or relay shown in block symbol,
In square frame with X be the time relay, and it is its delay disconnected node that symbol, which is equally KT, relay or contactor and
Relation corresponding to corresponding normally closed, normally opened node is that normally closed node typically disconnects in relay or powered contactor, dead electricity
When close, normally opened node typically closes in relay or powered contactor, disconnects during dead electricity.SB1/SB2/SB3 button phases
When in dynamic circuit breaker or dynamic circuit connector node, the function of an instantaneous folding can be realized, therefore a self-holding circuit is provided with the loop,
The auxiliary node of a contactor i.e. in parallel with button, as long as being had been turned on equivalent to loop, it is possible to keep for a long time unimpeded
State.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment simultaneously is not used to limit
The scope of the claims of the present utility model, all equivalence enforcements or change without departing from carried out by the utility model, it is intended to be limited solely by this case
In the scope of the claims.
