Abstract
A novel hydraulic excavator throttle control system mainly comprises a display screen, a CPU mainboard, a control knob, a potentiometer, a throttle motor and a throttle bracing wire. The novel hydraulic excavator throttle control system is structurally characterized in that the display screen displays the work mode of a hydraulic excavator, the CPU mainboard monitors the rotational speed of an engine in real time, and the potentiometer monitors the rotational angle of the throttle motor in real time and feeds back to the CPU mainboard in real time. When the work mode of the excavator is changed by operating the control knob, the CPU mainboard changes the length of the throttle bracing wire by the aid of the throttle motor, and adjusts the position of a throttle pull rod of the engine to realize real-time and accurate closed-loop control for the rotational speed of the engine. Simultaneously, moisture-proof, salt mist resistant and shock-resistant rubber materials are wrapped outside the throttle motor.
Description
Technical field
The utility model relates to a kind of novel hydraulic excavator throttle control system, belongs to the mechano-electronic field.
Background technology
At present, practical hydraulic crawler excavator throttle control system great majority are to rely on the throttle control system of import to realize Throttle Opening Control to motor on the market, this system is not for realizing the open-loop control system of accurately controlling in real time to throttle, complex structure not only, and maintenance difficult, delivery cycle is longer, and is on the high side, restricted the development of domestic excavator industry; Most throttle control systems of domestic use simultaneously do not have the function of moisture proof, anti-salt fog, antidetonation, and this just causes throttle control system to damage easily, has increased the replacement cost of product parts.
Summary of the invention
In order to overcome the deficiency more than the existing throttle control system, we have invented a kind of novel hydraulic excavator throttle control system, and it mainly is made up of display screen, cpu motherboard, control handle, potentiometer, throttle motor, acceleration cable.Its architectural feature is potentiometer is installed on the closed-loop control that realizes on the throttle motor the real-time monitoring of the throttle motor anglec of rotation.
Its architectural feature of novel hydraulic excavator throttle control system described in the utility model is to be wrapped with at the throttle motor elastomeric material of the effect of playing moisture proof, anti-salt fog, antidetonation.
The utility model is owing to adopted said structure, have rational in infrastructurely, compact, cost is low, Throttle Opening Control precision advantages of higher, well remedied the shortcoming of existing hydraulic crawler excavator throttle control system, improved throttle control system the hydraulic crawler excavator control ability.
Description of drawings
Accompanying drawing is the utility model structure principle chart.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing, in the Throttle Opening Control operating process, send the throttle actuating signal by control handle (3), signal is transferred to cpu motherboard (2) and goes up and show from display screen (1), the instruction that cpu motherboard (2) will move is transferred to throttle motor (5), and throttle motor (5) is realized control engine oil amount by acceleration cable (6); If throttle motor (5) is controlled when not in place, potentiometer (4) can be given cpu motherboard (2) with the feedback information that detects and show on display screen (1), can adjust control handle (3) again and repeat above-mentioned information exchanging process this moment, thereby realize the accurate control to throttle.
Claims (2)
1. novel hydraulic excavator throttle control system, it mainly is made up of display screen, cpu motherboard, control handle, potentiometer, throttle motor, acceleration cable, and its architectural feature is potentiometer is installed on the real-time monitoring that realizes on the throttle motor the throttle motor anglec of rotation.
2. novel hydraulic excavator throttle control system according to claim 1 is characterized in that the throttle motor is wrapped with elastomeric material.
