Abstract
The utility model discloses a height positioning device of a forklift, which comprises a gantry mounting and a control circuit, wherein the gantry mounting comprises an internal gantry mounting and an external gantry mounting, an inductive switch fixed plate is arranged on the external gantry mounting, and is provided with a plurality of inductive switches which can move up and down, and induction blocks which correspond to the inductive switches are arranged on the internal gantry mounting. The utility model greatly reduces work intensity of operators, and has simple operation and convenient use, greatly improves efficiency of the forklift and prevents collide accidents of a fork and a shelf from happening.
Description
Technical field:
The utility model belongs to material conveying device, specifically is the height registration device that a kind of fork truck jack up unit is used.
Background technology:
Fork truck is the visual plant that large cargo loading and unloading such as freight container traffic industry, warehousing industry are used.Fork truck when work, work being raised to a certain certain height and carrying out operation often.When the door frame lifting altitude is higher, only rely on the eyesight of operating personal to carry out the location of pallet fork, not only efficient is low, and accuracy of positioning is relatively poor, the accident that pallet fork and shelf are collided takes place easily, bring a lot of inconvenience for the use of fork truck, so realize that the highly automated positioning function of fork truck is very necessary.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of accurate positioning, simple in structure, height registration device that degree of automation is high are provided.
The utility model is achieved through the following technical solutions:
A kind of fork truck height registration device, include door frame and control circuit, described door frame comprises inner upright mounting and outer mast, it is characterized in that: the inductive switch adapter plate is installed on the described outer mast, the inductive switch adapter plate is provided with a plurality of inductive switches, and the sensor block that cooperates with inductive switch is installed on the described inner upright mounting; The access Electronic Control Assembly is closed mutually through the interlocking button respectively in described each inductive switch end of incoming cables, and the leading-out terminal of each inductive switch directly inserts Electronic Control Assembly; The control end of described each inductive switch is connected in series the coil that is connected in series first relay behind the diode more respectively, again with each inductive switch leading-out terminal and receive Electronic Control Assembly; Be provided with two parallel branches between the leading-out terminal of described interlocking press-button switch and each inductive switch, be serially connected with one group of contact of the coil and first relay of slug relay in one of them parallel branch; Be serially connected with the coil of the switch that hoists, contactless switch, other another group contact of first relay in another parallel branch, another of first relay organized on contact and is connected to one group of contact of slug relay; Also include lifting motor, insert Electronic Control Assembly behind one group of contact of described lifting motor serial connection contactless switch.
Described a kind of fork truck height registration device, it is characterized in that: the inductive switch position can be adjusted on the described inductive switch adapter plate.
Start the switch that hoists, fork truck begins the operation that hoists.Operating personal is pressed the button with the cooresponding interlock switch of desired location according to the position that the inner upright mounting needs stop.
When the sensor block that is installed in the inner upright mounting bottom moves to the residing position of inductive switch cooresponding with it, inductive switch closure, relay coil energising beginning action.At this moment, the normally closed port of relay disconnects, contactless switch dead electricity, and then lifting motor outage, and inner upright mounting stops to rise; Simultaneously, the normal ported closure of relay, slug relay's coil electricity.After waiting to arrive the delay time that slug relay sets, the normal ported closure of slug relay, this moment, contactless switch got electricly, and lifting motor must be established beginning work by cable, and inner upright mounting continues vertical motion.
After sensor block passed through by the residing position of inductive switch cooresponding with it, inductive switch disconnected, and then the relay coil outage, at this moment, the normal ported off-state that reverts to of relay, slug relay's outage, the normal ported off-state that reverts to of slug relay; And the normally closed port of relay recovers closure state at this moment, the contactless switch normal power-up, and the lifting motor normal power-up, and then inner upright mounting continues vertical motion.
The utility model has the advantages that:
The utility model has not only alleviated the working strength of operating personal greatly, and simple to operate, easy to use, has improved the efficient of fork truck greatly, has avoided the collide generation of accident of pallet fork and shelf.
Description of drawings:
Fig. 1 is the schematic circuit diagram of a kind of height registration device of the utility model.
Fig. 2 is the left view at outer mast place.
Fig. 3 is the front view at outer mast place.
The specific embodiment:
A kind of fork truck height registration device, include door frame and control circuit, described door frame comprises inner upright mounting and outer mast, inductive switch adapter plate 15,16,17 is installed on the described outer mast, inductive switch 7,8,9 is set respectively on the inductive switch adapter plate 15,16,17, the sensor block 14 that cooperates with inductive switch 7,8,9 is installed on the described inner upright mounting; Electronic Control Assembly is inserted through interlocking press-button switch 6 respectively in described each inductive switch 7,8,9 end of incoming cables, and the leading-out terminal of each inductive switch 7,8,9 directly inserts Electronic Control Assembly; The control end of described each inductive switch 7,8,9 is connected in series the coil 13 that is connected in series first relay J 1 behind the diode 10,11,12 more respectively, again with each inductive switch 7,8,9 leading-out terminal and receive Electronic Control Assembly; Be provided with two parallel branches between the leading-out terminal of described interlocking press-button switch 6 and each inductive switch 7,8,9, be serially connected with the coil 5 of the J2 of slug relay and one group of contact 17 of first relay J 1 in one of them parallel branch; Be serially connected with on another group contact 19 of other another group contact 19, the first relay J 1 of coil 4, first relay J 1 of the switch 3 that hoists, contactless switch K1 in another parallel branch and be connected to one group of contact 16 of the J2 of slug relay; Also include lifting motor 2, Electronic Control Assembly is inserted in 18 backs, one group of contact of described lifting motor 2 serial connection contactless switch K1.
