Detailed description of the invention
Connection with figures and embodiment describe the utility model in detail below.
As shown in Figure 1-Figure 3, this device is made up of intrinsic safety type operator's station 1, PLC technology case 2, intrinsic safety type tachogen 3, peripheral sensor 4, Hydraulic Station 5, lubrication station 6, RHVC 7, motor 8, power supply 9.Wherein intrinsic safety type operator's station 1 comprises: display panel 18, LCDs 1, LCDs 2 11, guidance panel 19, mainly make handle 12, brake-applying handle 13), change-over swith 14, manually tightly stop button 16, emergency power off button 17, button 15, operator's station shell 20.PLC technology case 2 comprises: PLC 1, PLC 2 22, communication isolator 1, communication isolator 2 24, relay 25, circuit breaker 26, switching value division board 27, temperature polling instrument 28, rubber seal battery 29, Switching Power Supply 30, intrinsic safety electric source 31, PLC technology case explosion-resistant enclosure 32.
LCDs 1, LCDs 2 11 display panel 18 of intrinsic safety type operator's station (1) be equipped with, the both sides of guidance panel 19 are equipped with respectively mainly makes handle 12, brake-applying handle 13, change-over swith 14, manually tightly stop button 16, emergency power off button 17, and button 15 is equipped with in centre.Intrinsic safety type operator's station 1 and PLC technology case 2 are interconnected, intrinsic safety type tachogen 3 and peripheral sensor (4) output signal and PLC technology case 2 are connected to each other, PLC technology case 2 is connected with Hydraulic Station 5 and lubrication station 6, be connected with RHVC 7, RHVC 7 exports and is connected with motor 8 simultaneously.
Working process of the present utility model is: take PLC as Central Processing Unit (CPU), when gig runs, PLC in PLC technology case detects received signal, if conditions being possessed, safety return circuit adhesive, operator can operate simultaneously mainly make handle 12 and brake-applying handle 13 under manual mode, realize the lifting of gig and transfer, brake-applying handle 13 controls the size of oil pressure, the main size making handle 12 controlling run speed, two cover PLC work simultaneously, wherein PLC 1 is master control system, PLC 2 22 is monitored control system, often overlap PLC and have independently checking system, if there is a set of PLC to break down, single cover PLC is selected to work on by " emergency mode ".Two cover LCDs are overlapped PLC with two respectively and are connected by the communication modes of RS232, and the various state of the gig that two cover PLC gather and parameter are sent to two cover LCDs by communication isolator and show respectively.In addition, two cover PLC also gather the signal of the intrinsic safety type tachogen 3 being arranged on motor shaft and on drum shaft respectively, according to the data collected, calculate the range ability of gig, and are shown by LCDs.LCDs has touch function, modifies or fault clearance by touch manner or by change-over swith 14 to various Protection parameters, state.Manually tightly stopping button 16 and can in case of emergency press on intrinsic safety type operator's station 1, realizes the protection under equipment emergency and stopping.Press emergency power off button 17, the separating brake to prime power switch can be realized, ensure the power-off of hydraulic motor and electromagnetic valve, thus strengthen the safety and reliability of system.
By manually tightly stopping contact, major loop closes pulleying under pulleying on contact, hardware, hardware, protection fixed a point by upper pulleying bypass, lower pulleying bypass, hardware, RHVC fault, PLC mono-tightly stop, the PLC bis-tightly contact signal connection in series-parallel rear drive safety relay such as parking, the hardware security loop of component devices.When above arbitrary contact disconnects, safety return circuit all can be protected, and then implements brake measure to peripheral controlled plant.
When promoting this electrical controller, lowering operation time, export to the instruction of RHVC forward and backward by PLC, drive motor operates; When carrying out acceleration and deceleration, export by PLC the running velocity that 0-10V signal controls motor.The 0-10V speed signal that RHVC feeds back to the port of PLC compares with the impulse speed signal being fed back to PLC port by tachogen, and formation is overrun, owe speed, stall protection.
Structure of the present utility model is simple, processing ease, and the high and controller performance of control accuracy is stablized, and solves the speed governing of gig, control and a protection difficult problem, improves the transport capacity of system, enhance equipment reliability of operation and safety.
Professional and technical personnel likely makes numerous modifications and variations to the utility model by above technology and example.Therefore the present invention should not be restricted to above-mentioned example, but should be limited in additional right.
