Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the present embodiment comprises bearing coder 1 and the approach switch 2 that is installed on the goods shelf, and an irony that is installed on the pallet fork detects piece 6, its centre bearer coder 1 adopts the bearing incremental encoder, when pallet fork generation lifting, can rotate around self axis, thereby produce the orthogonal increment impulse singla; Approach switch 2 adopts magnetic approach switch, and it is installed on the goods shelf bottom, and after pallet fork dropped to the end, this detected piece 6 and triggers approach switch 2; Described bearing coder 1 is connected with approach switch respectively and is connected the SICOS display control switch that height display control switch 3(adopts ZAPI by signal wire (SW), have highly demonstration, the input of 1-10 numerical key, given layer instruction key # input and arbitrary height key O input function), this height display control switch connects Oil pump electrical machinery controller (adopting the three-phase AC power controller AC1 of ZAPI) by multiple twin CAN bus, this Oil pump electrical machinery controller connects Oil pump electrical machinery 5(and adopts ac three-phase asynchronous motor), be used for the work of control oil pump motor 5.Described bearing coder 1 and approach switch 2 consist of height impulse singla generation system; Height display control switch 3 is that signal is processed and display system, is used for receiving the signal that bearing coder 1 and approach switch 2 produce, and calculate, highly demonstration, and to the control of Oil pump electrical machinery controller 4; Oil pump electrical machinery controller 4 and Oil pump electrical machinery 5 consist of actuating system, to realize the elevating control of pallet fork.
The height Presentation Function of the present embodiment is as follows: during the car key switch opens, whether height display control switch 3 at first detects approach switch 2 and is triggered, if approach switch 2 is not triggered, then height display control switch 3 does not allow pallet fork to hoist, only allow to carry out pallet fork decline order, until pallet fork drops to the end.After pallet fork dropped to the end, the detection piece 6 that assembles on the pallet fork was triggered approach switch 2, and height display control switch 3 energizing signal according to the approach switch 2 that receives carry out zero setting to its shown pallet fork height value; This moment, the demonstration height value of height display control switch 3 was 0 meter, and system is in normal readiness for action, can allow to carry out normal pallet fork landing operation.When pallet fork carries out the landing operation, 1 rotation of band dynamic bearing coder, bearing coder 1 output orthogonal delta pulse signal, this signal sends to height display control switch 3 by signal wire (SW), the positive negative pulse stuffing number that height display control switch 3 bases receive accurately calculates the residing height of pallet fork, and by screen display out.
The lifting altitude automatic control function is as follows: the arbitrary height key O that presses height display control switch 3, then input desired lifting altitude by ten key to height display control switch 3, when hoisting by height display control switch 3 to Oil pump electrical machinery controller 4 transmitted signals, 5 work of control oil pump motor realize that pallet fork hoists, simultaneous altitude display control switch 3 calculates the real-time height at pallet fork place by the pulse that reception bearing coder 1 sends, when arriving the height of setting, height display control switch 3 sends danger signal fuel feed pump electric machine controller 4, Oil pump electrical machinery controller 4 control oil pump motors 5 quit work, thereby realize the automatic control function of pallet fork lifting altitude.
Lifting altitude given layer control function is as follows: when pallet fork rise be raised to ground floor shelf height after, stop to hoist, press the given layer instruction key # of height display control switch 3, height display control switch 3 reads the pallet fork height value of this moment, and this height value is decided to be the standard increment floor height of shelf.Needed to be raised to which layer, only used by ten key the multiple of standard increment floor height is inputted height display control switch 3, height display control switch 3 can calculate the required height that hoists of pallet fork.When pallet fork hoists, height display control switch 3 calculates the real-time height at pallet fork place by the pulse that reception bearing coder 1 sends, when arriving the height of setting, height display control switch 3 sends danger signal fuel feed pump electric machine controller 4, Oil pump electrical machinery controller 4 control oil pump motors 5 quit work, thereby realize the given layer control function of pallet fork lifting altitude, and this function is only suitable in each high identical shelf layer by layer.
