The capital construction ac elevator of mine pit uses frequent; the current overwhelming majority continues to use the automatically controlled control of mine main ac elevator; be automatically controlled of the same type of type of production mine hoist; indivedual manufacturer production automatically controlled only possesses mono-two-wire PLC controllable function; do not satisfy the requirement of capital construction mine hoist work particular surroundings, be embodied in incompatible brake block gap detection function, no gig back-up protection function, the dynamic deceleration point positioning function of no descending deceleration etc.On components and parts selection, controlling schemes, running precision, do not catch up with on-the-spot requirement, thereby cause that energy consumption height, control accuracy are poor, the fault rate height, function is few, safety performance is not high.
Summary of the invention
The purpose of this utility model is the special requirement of producing according to the capital construction mine, and a kind of PLC two wire system Multifunctional AC hoist control system is provided, and uses as the operation of capital construction pitshaft, lifting personnel, lifting material.Have multifunctional, safety, high reliability features.Can finish unit and promote task, can realize again and pit shaft hanging scaffold balanced operation.
The technical solution of the utility model is as follows: a kind of PLC two wire system Multifunctional AC hoist control system, this system comprise master control operator's station, vacuum high-voltage switch cabinet, vacuum high-pressure commutation cabinet, vacuum rotor quicken cabinet, elevating gear, be installed in master control on the gig master motor test the speed the range finding coder, be installed in monitoring on the elevator drum test the speed the range finding coder, be installed in hanging scaffold on the hanging scaffold construct descending dynamic deceleration range finding coder, brake block gap distance measuring sensor and backup protection unit; Described master control operator's station is formed by main control PLC, monitoring PLC, control microcomputer, operating unit and to the ups power of control microcomputer power supply; Control microcomputer is with free communications protocol and Siemens's main control PLC monitoring plc data communication, and monitoring PLC realizes and the main control PLC data communication with network read-write communication protocol NETR/NETW form; Main control PLC adopts Redundant Control with monitoring PLC; Vacuum high-voltage switch cabinet, vacuum high-pressure commutation cabinet, vacuum rotor acceleration cabinet and master control operator's station carry out the switching value transmitting control with point-to-point form; Master control test the speed range finding coder, monitoring test the speed range finding coder, hanging scaffold construct descending dynamic deceleration range finding coder all with the main control PLC of master control operator's station with monitor PLC and be connected with data line; Brake block gap distance measuring sensor is connected with data line with monitoring PLC with backup protection unit.
The principle of this system is: master control range finding coder, monitoring range finding coder, brake block gap distance measuring sensor, the hanging scaffold signal that descending dynamic deceleration range finding coder will collect respectively separately of constructing that tests the speed that tests the speed passes to main control PLC and monitoring PLC, main control PLC and monitoring PLC carry out data communication with the NETR/NETW agreement, finish gig operation corresponding state and working point control, drive vacuum high-voltage switch cabinet, vacuum high-pressure commutation cabinet, vacuum rotor acceleration cabinet, controlled energy is loaded into working machine and makes its safe operation the most at last.Gig plays the hanging piece stroke should be all the time less than shaft construction hanging scaffold stroke, both results relatively are the relative distance that gig plays hanging piece and hanging scaffold, and the comparative result of this distance and the descending deceleration distance of artificial setting is exactly to want the descending deceleration point of lifting winch that obtains.
Good effect of the present utility model is: the automatically controlled automatically controlled mode of mine main ac elevator that changed of this ac elevator; it is the automatically controlled substitute of present capital construction ac elevator of mine pit; say the problem that is fit to capital construction mine interchange lifting and the descending dynamic deceleration of hanging scaffold construction balanced operation more from the production angle; realized the mode of brake block gap detection function and gig back-up protection and main automatically controlled one; the man-machine interface of hommization; the high-power vacuum device of complete series has improved the running environment of gig, has safe and reliable; fault rate is low; function is complete; be convenient to advantages such as operation.
