Technical field
The present invention relates to a kind of elevator electric control handling device.
Background technology
Current control lever on the market adopts potential device as main components, potential device is exactly swept resistance, because the moving contact moment of swept resistance does not stop sweeping action, in the course of time be easy to damage, reliability is very low, and the center adjusting potential device is a very difficult thing, and center is not adjusted, the speed of starting is very difficult control, is related to the safety performance of gig.Due to, gig is the bottleneck device in colliery, and control lever goes wrong, and whole gig will be paralysed, and whole ore deposit just faces stopping production, so control lever is the equipment of most critical.
Summary of the invention
The object of this invention is to provide a kind of elevator electric control control lever.
Technical scheme of the present invention is, a kind of elevator electric control control lever, in gig operator's station, base plate is housed, base plate is equipped with rotating shaft, in one end of rotating shaft, control lever is housed, the rotating shaft of the both sides of base plate is respectively equipped with microswitch cam and displacement pickup cam, microswitch cam has zero-bit recess, on base plate, microswitch cam side is equipped with zero-bit micro-switch respectively, promotes micro-switch, is transferred micro-switch, and the contact of zero-bit micro-switch is stuck in zero-bit recess; On base plate, displacement pickup is equipped with in displacement pickup cam side; Zero-bit micro-switch, promote micro-switch, transfer micro-switch, displacement pickup cam connects on elevator electric control circuit.
Described elevator electric control circuit comprises PLC mainboard, zero-bit micro-switch, promotes micro-switch, transfers the digital quantity input pin that micro-switch connects PLC mainboard, and displacement pickup connects the simulation volume input pin of PLC mainboard.
Displacement pickup is Hall displacement transducer.
The present invention has following technique effect, and 1, adopt advanced sensor technology and machinery to combine together, performance and stability go up hundred times well than common control lever.2, owing to adopting contactless displacement transducer technology, be not easy to damage.3, without exposed circuit card, anti-interference resistance is more much better than than common.Circuit is simple, non-maintaining.4, Hall displacement transducer is a kind of linear unit belonging to metal induction, after switching on power, in the sensitive surface of switch by generation alternating magnetic field, when metal object is close to this sensitive surface, then produce eddy current in metal and drawn the energy of oscillator, make the linear attenuation of oscillator output amplitude, then complete the object of Poul Dorset Sheep object according to the change of decrement.This displacement pickup has fricton-tight contact, not by the impact of the non-metal factors such as dust during work, and low-power consumption, the long life, under can being used in various mal-condition.5, adopt High Performance micro-switch outbound course signal, masterpiece for micro-switch action reed, is produced snap action when action reed is displaced to transformation point by microswitch cam, makes the moving contact of action reed end and fixed contact quick-make or disconnection.After the application force in microswitch cam is removed, action reed produces counteragent power, after microswitch cam reverse stroke reaches the action transformation point of micro-switch reed, instantaneously completes counteragent.The contact spacing of micro-switch is little, actuating length is short, little by power, break-make is rapid.The responsiveness of its moving contact and microswitch cam responsiveness have nothing to do.6, human oriented design of the present invention, feel spy is good.Justification function 500,000 nothings are damaged by experiment, durable in use.

Detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Fig. 8, a kind of elevator electric control control lever, base plate 4 is housed in gig operator's station 1, base plate 4 is equipped with rotating shaft 3, in one end of rotating shaft 3, control lever 2 is housed, the rotating shaft 3 of the both sides of base plate 4 is respectively equipped with microswitch cam 5 and displacement pickup cam 6, microswitch cam 5 has zero-bit recess 11, on base plate 4, microswitch cam 5 side is equipped with zero-bit micro-switch 8 respectively, promote micro-switch 9, transfer micro-switch 10, the contact of zero-bit micro-switch 8 is stuck in zero-bit recess 11, on base plate 4, displacement pickup 7 is equipped with in displacement pickup cam 6 side, and displacement pickup 7 is Hall displacement transducer, zero-bit micro-switch 8, promote micro-switch 9, transfer micro-switch 10, displacement pickup cam 6 connects on elevator electric control circuit, described elevator electric control circuit comprises PLC mainboard, zero-bit micro-switch 8 connect the digital quantity input pin of PLC (CPU226) mainboard I2.2 and COM pin, promote micro-switch 9 connect the digital quantity input pin of PLC (CPU226) mainboard I1.7 and COM pin, transfer I2.0 and the COM pin that micro-switch 10 connects the digital quantity input pin of PLC (CPU226) mainboard, displacement pickup 7 meets A+ and A-of the simulation volume input pin of PLC mainboard, the Q0.2 pin of PLC (CPU226) mainboard, Q0.3 pin, COM pin, VO pin, MO connect frequency converter, promotion signal, lower discharge signal, digital signal, speed signal, analog signal is exported respectively to frequency converter, Frequency Converter Control motor, motor drives gig.
Principle of work of the present invention:
The present invention adopts Hall displacement transducer, is non-contact inductive, adopts displacement pickup cam 6 and the distance of reaction of displacement pickup 7 to change and the direct current signal that produces 0 ~ 10V changes.When control lever 2 is in zero position, the interval 0.5mm of displacement pickup cam 6 and displacement pickup 7, at this moment displacement pickup 7 exports 0VDC, when control lever 2 forward direction promotes, displacement sensor cam 6 is more and more far away with the distance of displacement pickup 7, and the output of displacement pickup 7 also linearly increases, when control lever 2 pushes forward 45 degree to, distance between displacement pickup 7 and displacement sensor cam 6 is exactly 10mm, and at this moment displacement pickup 7 exports 10VDC; When control lever 2 is toward when pulling back, distance between displacement sensor cam 6 and displacement pickup 7 is more and more less, output voltage is also more and more less, 0V is recovered to during zero position, pull on control lever 2, the distance between displacement sensor cam 6 and displacement pickup 7 is more and more far away, and output voltage strengthens again gradually, until when the distance between displacement sensor cam 6 and displacement pickup 7 is 10mm, output voltage is 10VDC.
Because control lever 2 to need to three signals to PLC mainboard, be respectively transfer, promote, zero-bit.Microswitch cam 5 is adopted to control zero-bit micro-switch 8 respectively, promote micro-switch 9, transfer micro-switch 10; Zero-bit micro-switch 8, for exporting zero signal, promotes micro-switch 9 and exports promotion signal, transfers micro-switch 10 and exports lower discharge signal.When control lever 2 is zero-bit, a reverse action is opened in fine motion, exports normally closed point to PLC mainboard; When control lever is toward when transferring direction promotion, the action of zero-bit micro-switch, normally closed change is often opened, and output signal disconnects; Transfer micro-switch 10 action, normal opening and closing is closed, and exports lower discharge signal to PLC (CPU226); When control lever 2 draws toward direction of improvement, promote micro-switch 9 action, export promotion signal to PLC (CPU226).
