Detailed description of the invention
Known see Fig. 1, fork of forklift truck operation monitoring system comprises the telltale 2 be arranged in forklift steering room, and be arranged on the camera 7 of fork of forklift truck unit 13, camera 7 can be arranged on pallet fork, the goods shelf of pallet fork unit 13 or keep off near shelf, be preferably mounted at goods shelf low side, so convenient position observed pallet fork and aim at, and stacking and handling goods.Camera 7 can record down the video around it in real time, forms vision signal.Telltale 2 is provided with wireless receiver 4, camera 7 is provided with wireless launcher 9, collection signal is delivered to wireless receiver 4 through wireless launcher 9 by camera 7, Received signal strength is delivered to telltale 2 by wireless receiver 4, time fork truck normally works, chaufeur shows the video of goods, shelf and obstacle near the pallet fork that transmitted by camera 7 by telltale 2, avoid maloperation and risky operation, and without the need to facing upward head, lean to one side etc., mode directly detects by an unaided eye.
Wireless launcher 9 is arranged on pallet fork unit 13 together with camera 7.Wireless launcher 9 is connected by video signal cable line B15 with camera 7, and the electromagnetic wave that wireless launcher 9 can be converted into the vision signal that camera 7 transmits certain rule sends.
Wireless receiver 4 is arranged in forklift steering room together with telltale 2.Wireless receiver 4 can accept the electromagnetic wave that pairing wireless launcher 9 is launched, and is reduced to vision signal.Common forklift lifting altitude is less than 13 meters, and the wireless launcher 9 chosen and wireless receiver 4 video letter transmission distance can by 15 meters of designs.Telltale 2 is connected by video signal cable line A14 with wireless receiver 4, and telltale 2 can be reduced to video the vision signal that wireless receiver 4 transmits and play.
Telltale 2 and wireless receiver 4 are powered by the system power supply 6 be arranged on pallet fork unit 13 by power camera 7 and wireless launcher 9 of the vehicle body power supply 1 of fork truck, and system power supply 6 is arranged near the pallet fork of pallet fork unit 13, goods shelf or gear shelf.In addition, between vehicle body power supply 1 and supervisory system, be provided with system switching 10, facilitate chaufeur to open and close system as required like this.
About system power supply 6, there are following three kinds of embodiments:
As shown in Fig. 2 (a), Fig. 2 (b), system power supply 6 is rechargeable battery, rechargeable battery can store certain electricity, and rechargeable battery mouth can at outgoing current under certain voltage, and mouth is connected by cable with wireless launcher 9 respectively at camera 7.Rechargeable battery can be powered to camera 7 and wireless launcher 9, and generally within continuous firing 10-12 hour, can be advisable for them, such as output voltage specification is 12V capacity is 240Ah.Rechargeable battery is provided with charging plug 3, when electricity deficiency, can when fork truck vehicle body power supply 1 charge, and rechargeable battery is connected to mains supply by charging plug 3, charges.Rechargeable battery, when its input end is by charging current, has protective circuit to ensure to stop exporting.
As shown in Figure 3, system power supply 6 is rechargeable battery, and rechargeable battery can store a small amount of electricity, and rechargeable battery mouth can at outgoing current under certain voltage, and mouth is connected by cable with wireless launcher 9 respectively at camera 7.Rechargeable battery can be powered to camera 7 and wireless launcher 9, and generally can be advisable for their work dozens of minutes, such as output voltage specification is 12V capacity is 24Ah.Rechargeable battery has input end, for charging.
For convenience of charging, forklift frame is provided with the power supply contact connector 11 connecting vehicle body power supply 1, and pallet fork unit 13 is provided with the power taking contact connector 12 matched with power supply contact connector 11, and power taking contact connector 12 connects rechargeable battery.Time the position of power taking contact connector 12 can allow each pallet fork drop to extreme lower position, power supply contact connector 11 can contact with each other respectively with two contacts of power taking contact connector 12, forms path.
Preferred version, can arrange shock absorber, prevent contact from damaging because of shock between power supply contact connector 11 and power taking contact connector 12.
Preferred version, the cover plate blocked can be arranged in power supply contact connector 11 upper end, this cover plate can prevent general dust dirt from dropping on contact, cause bad contact, premature breakdown, this cover plate can be opened by power taking contact connector 12 when pallet fork falls extreme lower position, can not affect power taking contact connector 12 and form path with power supply contact connector 11, and cover plate can realize upset and return by the torsion spring on fixed rotating shaft.
Preferred version, can on the cable of power supply contact connector 11 and vehicle body power supply 1 charge switch, be placed in the position be convenient to chaufeur and be convenient to handle, can be controlled by chaufeur, when work is not in a hurry, pallet fork is dropped to minimum, control vehicle body power supply 1 by this charge switch and charge to rechargeable battery.
As shown in Figure 4, system power supply 6 is super capacitor, ultracapacitor (supercapacitor, ultracapacitor), be again double layer capacitor (ElectricalDoule-LayerCapacitor), gold electric capacity, farad capacitor, carry out energy storage by polarized electrolytic matter.It is a kind of electrochemical element, but chemical reaction does not occur in the process of its energy storage, and this thermal energy storage process is reversible, also just because of this ultracapacitor can repeated charge hundreds thousand of time.Power density is high, can reach 300W/KG ~ 5000W/KG, is equivalent to 5 ~ 10 times of battery.Usually the capacitance of farad level can be reached under very little volume.Along with the exploitation of super capacitor technology, cost reduces gradually, is used widely in every field at present.Ultracapacitor can store electricity generally within 5-10 minute, can be advisable for their work, and such as super capacitor 14 specification is 12V100F (can be in series by the small-sized super capacitor of 4 3V100F).
For convenience of charging, forklift frame is provided with the power supply contact connector 11 connecting vehicle body power supply 1, and pallet fork unit 13 is provided with the power taking contact connector 12 matched with power supply contact connector 11, and power taking contact connector 12 connects super capacitor.Time the position of power taking contact connector 12 can allow each pallet fork drop to extreme lower position, power supply contact connector 11 can contact with each other respectively with two contacts of power taking contact connector 12, forms path.When each pallet fork drops to minimum, this path of vehicle body power supply 1 charges to super capacitor, and this super capacitor capacity is less, as long as the charging several seconds just can be full of.At least pallet fork will inevitably be dropped to once minimum in the operation of normal carrying stacking in 5 minutes, so can ensure there is electricity inside super capacitor always, camera 7 and wireless launcher 9 work uninterruptedly.
Preferred version, can arrange shock absorber, prevent contact from damaging because of shock between power supply contact connector 11 and power taking contact connector 12.
Preferred version, the cover plate blocked can be arranged in power supply contact connector 11 upper end, this cover plate can prevent general dust dirt from dropping on contact, cause bad contact, premature breakdown, this cover plate can be opened by power taking contact connector 12 when pallet fork falls extreme lower position, can not affect power taking contact connector 12 and form path with power supply contact connector 11, and cover plate can realize upset and return by the torsion spring on fixed rotating shaft.
