LCD MODULE is installed in the operator's compartment, is used to show safety state information, links to each other with controller through the CAN bus.
Acoustic-optic alarm links to each other with controller, and controller is installed in the electric control box on operator's compartment right side, is controlled at by controller and sends alerting signal when precarious position occurring.
The utility model is used for the safety monitoring device of multi-functional All-terrain Forklift, can car body too the bevelled situation issue out information warning and alarm signal, remind the operator to avoid risky operation; The tilting moment of monitor vehicle in real time when using the telescopic boom operation, restraint of labour mechanism running velocity or stop its operation fully, the generation of avoiding tumbling gives the alarm when exceeding a threshold value also; When the goods shelf flip angle surpasses a threshold value, it is carried out spacing, avoid goods to fall forward or backward.This device can well be guaranteed the vehicle job safety, avoids the generation of accident.
Description of drawings
Fig. 1 is the installation site of each component part of the utility model on multi-functional All-terrain Forklift.
Fig. 2 is the apparatus structure schematic diagram of the utility model.
Below in conjunction with accompanying drawing the content of the utility model is done further explain.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises controller 1, master cylinder pressure sensor 2, car body double-shaft tilt angle sensor 3, telescopic boom single shaft obliquity sensor 4, goods shelf single shaft obliquity sensor 5, telescopic boom extension elongation sensor 6, accessory means of identification 7, operating mechanism's flow regulating valve 8, LCD MODULE 9, acoustic-optic alarm 10.
Controller 1 can obtain the length that hydraulic pressure, car body inclination angle, telescopic boom and horizontal plane angle, goods shelf 13 and horizontal plane angle, telescopic boom in the telescopic boom lift oil tank 11 stretch out in real time through master cylinder pressure sensor 2, car body double-shaft tilt angle sensor 3, telescopic boom single shaft obliquity sensor 4, goods shelf single shaft obliquity sensor 5, telescopic boom extension elongation sensor 6.
When the car body inclination angle is excessive (the fore-and-aft direction inclination angle is spent greater than 10 greater than 25 degree or left and right directions inclination angle), controller 1 will show " car body too tilts " warning through LCD MODULE 9, and drives acoustic-optic alarm 10 work.
The length that controller 1 stretches out through 11 hydraulic pressure in the lift oil tank, car body inclination angle, telescopic boom 12 and horizontal plane angle, telescopic boom 12, and the connection location 14 of quality, lift oil tank and the car body of known telescopic boom (band pallet fork) and and the information such as connection location 15 of telescopic boom can calculate the quality of present load (goods on the pallet fork).Connection location 16 according to load quality, car body inclination angle, telescopic boom 12 length and telescopic boom and car body can calculate the tilting moment that present load produces with respect to vehicle front-wheel touchdown point.Connection location 16 according to car body inclination angle, telescopic boom (band pallet fork) quality, telescopic boom 12 length and telescopic boom and car body can calculate the tilting moment that telescopic boom produces with respect to vehicle front-wheel touchdown point.Load and telescopic boom 12 moment sums relative and vehicle front-wheel touchdown point are total tilting moment.The maximum tilting moment that vehicle allows then can calculate through car body quality (not comprising telescopic boom), body gravity, car body inclination angle.The maximum tilting moment that surpass to allow when total tilting moment 60% the time; Controller 1 Control work mechanism flow regulating valve 8 reduces operating mechanism's running velocity; Show " attention slide-out " warning message through liquid crystal indicator 9 simultaneously, and drive acoustic-optic alarm 10 work; The maximum tilting moment that surpass to allow when total tilting moment 80% the time, the mechanism's operation that quits work of controller 1 Control work mechanism flow regulating valve 8 shows " slide-outs through liquid crystal indicator 9 simultaneously! " warning message, and drive acoustic-optic alarm 10 work.
Controller 1 is judged current accessory type according to accessory means of identification 7, if accessory is a pallet fork, then judges goods shelf 13 and horizontal plane angle, surpasses 7 degree if goods shelf 13 leans forward, and then stops the forward swing of goods shelf 13, prevents the goods landing; If goods shelf 13 hypsokinesis surpass 14 degree, then stop goods shelf 13 hypsokinesis action, goods falls backward when preventing that telescopic boom 12 is raised to eminence.
