Description
Technical field
The present invention relates to engineering machinery field, more specifically, the present invention relates to a kind of control setup and method of operation thereof that is used for construction machinery and equipment.The invention still further relates to a kind of construction machinery and equipment that comprises this control setup.
Background technology
Be used for the control setup of the change speed gear box of engineering machinery vehicle such as loader, All-terrain Forklift, tipping bucket dumping car etc. at representative type, realize advance and retreat control and variable speed control via advance and retreat control stalk and variable speed control bar respectively usually construction machinery and equipment.Specifically, when needs advanced or retreat, chaufeur can be handled the advance and retreat control stalk by the operation advance and retreat control rod, to realize the advance and retreat control to construction machinery and equipment; And when needs changed the high low speed of construction machinery and equipment, chaufeur can be handled the variable speed control bar by the operation gear-change hand lever, to realize the variable speed control to construction machinery and equipment.
In addition, also proposed to handle simultaneously the solution of advance and retreat control stalk and variable speed control bar in the prior art by single joystick.
Yet, in the prior art, all be the diverse location place that advance and retreat control stalk and variable speed control bar with change speed gear box are separately positioned on operator's compartment.This set all can take more cab space usually.
It is big that above-mentioned dual mode takies cab space, chaufeur work traveling comfort and poor stability, inconvenient operation, inefficiency.
Though the construction machinery and equipment that has existed the automatically controlled single pole of employing system to control, it comprises automatically controlled single pole, electronic controller and electro-hydraulic reversing valve system, this electronic system architecture complexity, and cost is high, and applicability is limited.
Therefore, this area needs a kind of variable speed control bar and advance and retreat control stalk can being integrated so that save limited cab space, cost is low and can alleviates the control setup that is used for construction machinery and equipment of driver's fatigue especially.
Summary of the invention
At the above-mentioned defective that exists in the prior art, main purpose of the present invention is to provide a kind of control setup, it can integrate the variable speed control bar and the advance and retreat control stalk of the change speed gear box of construction machinery and equipment, and has the structure of single actuating lever, keeps simple in structure simultaneously, cost is lower.
According to an aspect of the present invention, provide a kind of control setup that is used for construction machinery and equipment, comprising: joystick; First control stalk with described joystick flexible connection; Can be around second control stalk of the rotational of described first control stalk, it pivots with described joystick by a pivot and is connected, described joystick drives the described first control stalk axial motion around the rotation of described pivot, and described joystick drives the rotational of described second control stalk around described first control stalk around the rotational of described first control stalk.
According to a further aspect in the invention, provide a kind of construction machinery and equipment, comprise above-mentioned control setup.
According to another aspect of the invention, provide a kind of method of operation of operating above-mentioned control setup, wherein: activate joystick, make the rotational of joystick, drive the rotational of second control stalk around described first control stalk around described first control stalk; Perhaps activate joystick, it is moving that joystick is pivoted around pivot, drives and the movable bonded assembly first control stalk axial motion of joystick.
Control setup of the present invention is compared with traditional mechanical double bar controlling, occupies less cab space, makes chaufeur more comfortable and safe, and more convenient operation, has improved work efficiency; Compare with the electronic type control stalk, significantly cost-cutting.
This control system is simple to operate, and cost is low, and can alleviate driver's fatigue.For example, in the loader that adopts this one-lever control system, chaufeur is when operation, only need the left-handed operation deflector, before and after the right-hand operated single lever control handle or move up and down, needn't consider that needing which root bar the right hand is placed on controls, the shovel dress of can concentrating one's energy.
Concrete feature and advantage of the present invention will be described in detail in the explanation of following illustrative embodiments of the present invention.
