Description
Technical field
The present invention relates to the semi-automatic adjusting microinching system of hydraulic moment changeable fork truck.
Background technology
Fork truck is industrial transportation vehicle, refer to member pallet cargo is loaded and unloaded, stacking and short distance hauling operation
Various wheeled carrying vehicles.It is widely used in harbour, station, airport, goods yard, factory floor, warehouse, Transfer center and dispatching
Heart etc., and handling, the transport operation that pallet cargo is carried out in cabin, compartment and container can be entered, it is palletized transport, container
Essential equipment in transport.
But, hydraulic moment changeable fork truck in the market has following shortcoming：
First, in materials handling process, it is often necessary to which four limbs together operate fork truck, driver is easily tired；
2nd, compared with static pressure transmission car, forklift operator efficiency is relatively low, influences efficiency；
3rd, it is fitted without brake pressure detection means so that fork truck has potential security risk.
Therefore, the present inventor designs a kind of semi-automatic adjusting microinching system of hydraulic moment changeable fork truck, and thus this case produces.
The content of the invention
It is an object of the invention to provide a kind of semi-automatic adjusting microinching system of hydraulic moment changeable fork truck, to improve the comfort level of fork truck
And operating efficiency, that strengthens fork truck uses safety.
In order to reach above-mentioned purpose, solution of the invention is：
The semi-automatic adjusting microinching system of hydraulic moment changeable fork truck, including digital control module, load control module, engine speed are adjusted
Regulating device and brake pressure detection means, load control module are made up of operation handle and electric control multi-way valve, are set in operation handle
There is the potentiometer that mechanical trip is converted to voltage variety, the input of digital control module is connected with the current potential in operation handle
Meter, brake pressure detection means and engine speed detection device, the output end of digital control module be connected with electric control multi-way valve and
Engine speed modulation device；
Be input into voltage variety to digital control module by potentiometer, and digital control module is by the tune to electric control multi-way valve
Section realizes the operation of door frame；Brake pressure detection means monitors the size between brake pressure and engine torque, and its is defeated
Enter to digital control module, digital control module realizes the regulation to engine speed by engine speed modulation device；Hair
Motivation speed detector monitors engine speed, and is converted into data signal and is input into digital control module, numeral control
Molding block realizes the regulation to engine speed by engine speed modulation device.
The electric control multi-way valve is hydraulic control valve.
The brake pressure detection means is brake pressure sensor.
The engine speed modulation device passes through mechanical pull bar and is connected with engine speed modulation bar.
The engine speed detection device is engine speed sensor.
After such scheme, the present invention introduces digital control module on hydraulic moment changeable fork truck, and matches somebody with somebody as core
Other modules and device are closed, not only makes driver in door frame operating process without stepping on accelerator pedal, bring more comfortable behaviour
Experience, raise labour efficiency, and realize automatically controlling for engine speed change, the security performance of fork truck is improve one
Individual class.Meanwhile, the portability of whole system is strong, only need to accordingly adjust and change, and just can apply the vehicle in different moneys
On.
Brief description of the drawings
Fig. 1 is structure principle chart of the invention.
Specific embodiment
As shown in Fig. 1, the semi-automatic adjusting microinching system of hydraulic moment changeable fork truck that the present invention is disclosed, including digital control module, load
Lotus control module, engine speed modulation device and brake pressure detection means, load control module is by operation handle and automatically controlled
Banked direction control valves is constituted, and operation handle is provided with the potentiometer that mechanical trip is converted to voltage variety, this embodiment it is automatically controlled many
