The utility model discloses the advantage that has is: the pump motor can be adjusted according to the condition.

Description

Forklift lifting speed regulation device

Technical field

The utility model relates to fork truck accessory technical field, especially relates to a kind of forklift lifting speed regulation device.

Background technology

In forklift lifting process, pump motor is high rotary speed working all the time.When chaufeur carries out fine motion or thin tail sheep operation, pallet fork is easily shaken, and cannot carry out accurate stacking to goods.Meanwhile, because pump motor continues to carry out high rotary speed working, storage battery energy loss must be caused, cause fork truck work-hours short.And because motor continues to carry out high rotary speed working, the idle work that hydraulic efficiency pressure system is done is more, causes hydraulic efficiency pressure system temperature rise fast, easily produce the faults such as leakage of oil.

Summary of the invention

The purpose of this utility model is to provide a kind of forklift lifting speed regulation device, and it has pump motor and can according to circumstances adjust, thus the feature be convenient to chaufeur manipulation, extended fork truck work-hours, not easily produce leakage of oil.

The technical scheme that the utility model adopts is: forklift lifting speed regulation device, comprise lower end and be hinged at the joystick on the vehicle frame of this fork truck and the multiway valve be fixed on this vehicle frame and pump motor, and the lower end of this joystick is hinged with rigid link, the function unit of the lower end hinge multiway valve of rigid link, described vehicle frame is fixed with the speed control switch that hoists, this speed control switch that hoists has the stroke probe that in the vertical direction extends, simultaneously, the avris of rigid link is fixed with the touch panel in level, this touch panel and the trip probe match, and, this speed control switch signal that hoists is connected with controller, this controller signals connects this pump motor.

Described stroke probe is to downward-extension.

The utility model is advantageously: pump motor can according to circumstances adjust, thus is convenient to chaufeur manipulation, extends fork truck work-hours, not easily produces leakage of oil.Forklift lifting speed regulation device of the present utility model in use, stroke probe can detect the distance of rigid link in company with joystick movement at any time, and the speed control switch that hoists by the signal transmission of joystick miles of relative movement that detects to controller, controller is according to the rotating speed of aforementioned signal control pump motor.That is, pump motor is without the need to remaining high rotating speed, eliminates the defect that chaufeur is not easily handled, storage battery energy loss large, hydraulic efficiency pressure system is easy to leakage of oil.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 is the schematic perspective view of embodiment of the present utility model;

Fig. 2 is the A portion enlarged drawing of Fig. 1.

In figure:

10, joystick;

20, multiway valve;

30, rigid link, 31, touch panel;

40, hoist speed control switch, and 41, stroke probe;

100, vehicle frame.

Detailed description of the invention

Embodiment, is shown in shown in Fig. 1 and Fig. 2: forklift lifting speed regulation device, comprising: lower end is hinged at the joystick 10 on the vehicle frame 100 of this fork truck, and the multiway valve 20 be fixed on this vehicle frame 100 and pump motor (not shown on figure).The lower end of this joystick 10 is hinged with rigid link 30, the function unit of the lower end hinge multiway valve 20 of rigid link 30.Preferably mode is: the lower end of joystick 10 is provided with the eave tile of " 7 " font, and rigid link 30 is hinged at the end of eave tile, thus after the upper end of movable joystick 10, this rigid link 30 moves up and down.

Further say, this vehicle frame 100 is fixed with the speed control switch 40 that hoists, this speed control switch 40 that hoists has the stroke probe 41 that in the vertical direction extends.Such as, stroke probe 41 is to downward-extension.Meanwhile, the avris of rigid link 30 is fixed with the touch panel 31 in level, and this touch panel 31 and the trip probe 41 match.That is, touch panel 31 moves up and down in company with rigid link 30, shake-up stroke probe 41 in various degree after touch panel 31 moves up and down, and this speed control switch 40 that hoists learns the signal moving up and down distance of rigid link 30 by the degree of being touched of stroke probe 41.And this speed control switch 40 signal that hoists is connected with controller (not shown on figure), and this controller signals connects this pump motor.That is, the signal transmission moving up and down distance of rigid link 30 that just produces of this speed control switch 40 that hoists is to this controller, and this controller is according to the rotating speed of aforementioned signal control pump motor.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
