The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
As described in Figure 1, a kind of fork truck weighting apparatus comprises 4 LOAD CELLS 3 that link to each other with control display unit 6 with lead.LOAD CELLS 3 is located at respectively on 2 standard fork plates 1, and each fork plate 1 is provided with 2.Respectively be provided with cover plate 2 on 2 fork plates 1, cover plate 2 is respectively fixed to the position that sensor is weighed.Vertical component at each fork plate 1 afterbody is provided with a pair of crotch 5, and this can be buckled in respectively on the upper and lower transverse slat 8,9 of fork truck bont, and can dismantle easily, as shown in Figure 3 upper and lower transverse slat 8,9 correspondences of crotch 5 and fork truck bont.
Also be provided with L/C sensitivity adjustment potential device between each LOAD CELLS 3 and the control display unit.This L/C sensitivity adjustment potential device is located at the connection box 7 that is arranged in fork plate 1 afterbody vertical component, and seals with protective cover 4.This be weighting apparatus before dispatching from the factory in order to adjusting four jiaos of balances of weighing, adjust before assembly dispatches from the factory finish after, needn't carry out the adjustment of four jiaos of weighting errors again when the user uses.Control display unit of the present utility model also is provided with the software that can revise four jiaos of balances of weighing automatically, owing to not at the claim protection domain, do not elaborate at this.
As shown in Figure 3, described control display unit 6 comprises amplifying circuit, filter circuit, analog-to-digital conversion circuit, central process unit, power supply circuit, button and read-out; L/C sensitivity adjustment potential device connects the input end of amplifying circuit, and its mouth connects central process unit by analog-to-digital conversion circuit; Button links to each other with central process unit with read-out; Power supply circuit connects power supply.The utility model also is provided with the bluetooth communication interface circuit, and this circuit is connected with central process unit by lead; In addition, the utility model also is provided with printing device, and the input end of this equipment is connected with central process unit.Power supply of the present utility model is a recharge-able battery, and 12V/1.2Ah includes charger, but battery continuous working 30 hours, and low electric weight indication is arranged.
