The specific embodiment
Below in conjunction with drawings and Examples the utility model specific embodiment is described:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, it shows an embodiment of the present utility model, the utility model forklift and control method thereof, described forklift comprises car body 1, fork pin 2, promote door frame 3, be installed on the storage battery in the car body 1, the electrical motor that driving car body 1 travels and the change speed gear box that changes the electric motor drive ratio; Described lifting door frame 3 is arranged at car body 1 front side, promotes door frame 3 and is made up of inner frame and hard-wired lateral frame that can lifting, pitch pin 2 be installed on can the inner frame of lifting on; The bottom of described car body 1 is equipped with and drives the drive wheel 101 that car body travels and turns to; Above-mentioned forklift parts disclose in the prior art, certainly, also comprise the fork castor of installing on the fork pin 2 as shown in Figure 1 201 that plays support and auxiliary rolling action in the prior art, the below of described car body 1 also can be provided for playing the balance wheel (not shown) of auxiliary rolling and balance car body in drive wheel 101 both sides.
Above-mentioned drive wheel 101 comprises adjusts the axle drive shaft that turning cylinder 103 that wheel turns to and wheels are travelled;
Above-mentioned forklift also comprises by left-right rotation controls that above-mentioned drive wheel 101 turns to and by swinging up and down the joystick 5 of control drive wheel 101 moving velocitys; Joystick 5 bottoms are installed on the above-mentioned turning cylinder 103, and joystick 5 connects change speed gear box, and the input shaft of change speed gear box connects the output shaft of electrical motor; The output shaft of change speed gear box finally drives drive wheel 101 and rolls.
Above-mentioned joystick 5 comprises the braking distance that travels stroke and drive wheel 101 is braked of control change speed gear box increasing motor transmitting ratio at least.So, this forklift can be controlled the driving process of forklift by swing and the rotation of joystick 5; Because this maneuverability pattern is similar to the manipulation process of running car, compares the process of all being operated by button, and is convenient, also match operation person's use habit more; The same result of use that in vehicular drive, draws for a long time for people, to the manual control of driving process, more direct, along with the growth of operating time, can further increase operator's use proficiency, further improve the efficient of this forklift when goods is piled up.
In order to increase the efficient of operator when braking, be connected with the pull back spring 102 that joystick 5 is returned to braking distance by the stroke that travels between above-mentioned joystick 5 and the turning cylinder 103; Increased pull back spring and also had a benefit to be exactly, in case occur the operator lost joystick or no one when handling whole locomotive body be in braking procedure, avoided unexpected generation.
In order further the parts of the operating process of forklift to be concentrated on the joystick, above-mentioned joystick 5 is provided with fork pin rising button 501 and the fork underfooting of rising and descending for control fork pin 2 and falls button 504; Also be provided with the travel direction switching push button 502 that control drive wheel 101 advances or retreats on the described joystick 5.So, the top of control lever is very convenient and integrated clearly nearly all control member for the operator provides convenience, finally can improve the work efficiency of operator and whole forklift certainly.In order to increase the usage space of button on the control lever, some and the button of controlling procedure relation not quite or often do not use can be integrated on the car body 1: plug the switch lock 104 of key and prevent unexpected emergency stop switch 105 such as shown in Figure 3 being used for.
For the 6 couples of operators of goods that prevent from pitching on the pin 2 cause accidental damage, the rear of above-mentioned lifting door frame 3 is equipped with fender 301, and the material of fender 301 is transparent case hardened glass or transparent resin.
Consider the stability of forklift to the importance of the efficient of whole forklift, above-mentioned stating promotes the equalizing gear 4 that is equipped with on the door frame 3 for both sides, balanced hoisting door frame 3 front and back weight; So, the stressed meeting in lifting door frame both sides of forklift is more even, is not easy to cause whole vehicle to topple over, and has simultaneously also protected lifting door frame 3 stability of structure, is unlikely to be subjected to too much one-sided moment of flexure and causes distortion.The principle of work of whole equalizing gear 4 mainly is that to promote door frame 3 be benchmark as shown in Figure 2, calculates the gravity numerical value that promotes the door frame both sides by the gravity equation, and gravity is carried out balance.
A kind of structure of above-mentioned equalizing gear 4 is provided in the present embodiment, and wherein, equalizing gear 4 comprises clump weight 401, and drives the driver train that clump weight 401 moves forward and backward; This driver train comprises that symmetry is installed on the housing 406 that promotes door frame 3 left and right sides, and buckle 403 is installed on the housing 406; The inside of housing 406 is equipped with screw mandrel 407, and screw mandrel 407 two ends are rotatably installed in the bearing seat 405, and screw mandrel 407 1 ends pass bearing 405 and in the end motor 404 are installed, and motor 404 and bearing seat 405 all are fixedly mounted in the housing 406;
Install on the above-mentioned screw mandrel 407 by being threadably engaged in travelling nut piece 402 mobile on the screw mandrel 407, travelling nut piece 402 passes above-mentioned buckle 403, and two ends, above-mentioned clump weight 401 left and right sides are installed in travelling nut piece 402 tops.
The type of drive of above-mentioned feed screw nut has guaranteed stationarity and the particularity that whole clump weight moves.
For the ease of the operation of whole equalizing gear, the weight sensor 202 that calculates lade gravity on the fork pin 2 is installed on the above-mentioned fork pin 2; Joystick 5 is provided with the equalizing gear control button 503 that the weight data that calculates according to weight sensor 202 comes the clump weight 1 in the driven equilibrium mechanism 4 to move.Thus, on joystick, can realize the automatic operation of equalizing gear 4 equally; Certainly the equalizing gear control button 503 of this moment is opened back adjustment automatically, after closing, carries out locking position.
The utility model also provides the control method of above-mentioned forklift, and this control method comprises:
Drive the step that car body travels to lower swing joystick to the stroke that travels;
Rotate joystick and adjust the step of car body drive wheel travel direction;
Continuation increases the step of car body moving velocity to the lower swing joystick;
Upwards swinging joystick to braking distance slows down car body until the step that stops.
This method of operation has changed traditional operating mode, and its advantage is consistent with the advantage of this forklift, has namely increased the convenience of operator to the forklift operation, has improved the efficient of operation forklift.
In the above-mentioned control method, after loosening joystick, joystick is rocked to braking distance automatically car body is slowed down until stopping.
By reference to the accompanying drawings the utility model preferred implementation has been done detailed description above, but the utility model is not limited to above-mentioned embodiment, all are that the improvement in the ken that those of ordinary skills were possessed that carry out on the basis all drops in the protection domain of the present utility model with thought of the present utility model, modal variation has: in Fig. 1, the stroke that travels of joystick is subdivided into braking distance B, low speed stroke S, high speed stroke K and following braking distance B are so that the stroke that travels has different speed intervals; Or the position of equalizing gear moved, perhaps clump weight is arranged at below of equalizing gear etc.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
