Embodiment
As shown in Figure 1; A kind of internal combustion counterbalanced weight fork truck seat sensory perceptual system is made up of key switch, centring control box, seat switch, operating system controller, hydraulic multitandem valve piece, forward-reverse gear electromagnetic valve piece, direction switch 1, forward relay 2, reverse relay 3, indicator lamp 4, alarm buzzer 5, inclination electromagnetic valve 6, unloading electromagnetic valve 7, first electrical equipment output contact 8, second electrical equipment output contact 9, the 3rd electrical equipment output contact 10, the 4th electrical equipment output contact 11.
The first via of key switch connects positive source, power cathode ground connection through the main power source input interface; The second tunnel of key switch keeps off interface through ON retaining interface with the ON of operating system controller and is connected; Its branch road is exported contact 11 with the 4th relay in the direction switch 1 and is connected; The 4th relay output contact 11 links to each other with second relay output contact 9; First relay output contact 8 is connected with preceding inlet side in the forward-reverse gear electromagnetic valve piece through the contact of forward relay 2; Its branch road is connected with the perceptual signal interface that advances of operating system controller; The coil of forward relay 2 is connected with the control signal interface that advances of operating system controller; Retreating hold in the contact of the 3rd relay in the direction switch 1 output contact 10 through reverse relay 3 and the forward-reverse gear electromagnetic valve piece is connected, and its branch road is connected with the perceptual signal interface of retreating of operating system controller, and the coil of reverse relay 3 is connected with the control signal interface of retreating of operating system controller; The key switch Third Road is connected with the starting relay input interface of centring control box through START retaining interface.The centring control box is connected with the startup input interface of operating system controller through starting output interface, and the operating system controller is connected with seat switch with output interface through the switch input respectively; Be connected with indicator lamp 4 through the indicator lamp signal output interface; Be connected with alarm buzzer 5 through the buzzer signal output interface; Respectively through the inclination electromagnetic valve 6 in electromagnetic valve signal output interface and the hydraulic multitandem valve piece with unload electromagnetic valve 7 and be connected.
Wherein, centring control box and operating system controller are all the outsourcing product.
During operation, the operator plugs key earlier, opens key switch; After correctly taking seat subsequently, the normally closed one tunnel normally closed signal that provides of seat switch, operating system controller carry out the internal information processing after receiving this signal; One the tunnel gives forward relay 2 and reverse relay 3 power supplies, and relay gets electric, magnet coil attracting electric relay output contact; Electromagnetism direction switch 1 input end gets electric, and internal combustion counterbalanced weight fork truck can the normal commutation mobility operation.Promptly when direction switch switched to forward gear, second relay output contact 9 upwards was connected with first relay output contact 8, thereby was communicated with the preceding inlet side in the forward-reverse gear electromagnetic valve piece; Retreat when retaining when direction switch switches to, second relay output contact 9 is connected with the 3rd relay output contact 10 downwards, thereby retreats end in the connection forward-reverse gear electromagnetic valve piece.Other one tunnel normally closed electric shock connects and hoists/the hydraulic multitandem valve piece electromagnetic valve power supply of inclination multiway valve, electromagnetic valve gets electric opening and hoists/the inclination hydraulic circuit, carry out door frame and hoist/tilt can normal running preparation.When the operator switched to any control gear, indicator lamp 4 lighted, simultaneously alarm buzzer 5 buzzings.
When fork truck carried out Job Operations, the operator left seat, the seat switch disconnection, and the operating system controller breaks off the power of electromagnetic valve that moves forward and backward on the hydraulic transmission box through control forward relay 2 and reverse relay 3, at this moment the fork truck automatic train stop; Simultaneously, the hoisting of door frame/inclination Job Operations is by the automatic shut-down operation of same principle.If the operator gets back in 5S on the seat, the operating system controller can not carried out aforesaid operations, and fork truck still can continue to go and operation.As to cancel the operating system controllable function, and take seat again, and reversing handle is turned back to neutral gear position, after this could carry out normal operation by start the engine.
