Description
Technical Field
The invention belongs to the field of engineering machinery, and particularly relates to a protection method device and system for rapid movement of a working arm of a drilling trolley.
Background
The power sources of engineering machinery (hereinafter referred to as a vehicle) such as a drilling jumbo are from an engine and a high-voltage motor, and when the vehicle is under different working conditions and an operator needs to move the position of a working arm, the vehicle is driven by different power sources. With different power sources, the operator needs to adjust the speed of the moving working arm.
When the vehicle works, the engine is required to be started to drive the vehicle to the working surface, and in the driving process, the position of the working arm is required to be moved according to road conditions, and the power source of the working arm is from the engine. After the vehicle reaches the working face, an operator connects a high-voltage cable of the vehicle body to a power distribution cabinet of the working site, and then adjusts the position of a working arm according to the working requirement of the working face, and the power source of the working arm is from a high-voltage motor.
When an operator works through the high-voltage motor, the high-voltage motor is constant in rotating speed and always in a high-rotating-speed running stage of the motor, the flow provided by the hydraulic system for the working arm can meet the requirement of quick movement, and the operator can move the position of the working arm only through the working arm operating rod. However, when the operator moves the working arm through the engine, the engine can be started and then run in a lower rotating speed range, the hydraulic system cannot provide enough flow, the working arm moves slowly, and at the moment, the operator is required to lift the engine rotating speed through the accelerator pedal in the driving area. The operator driving area and the area for adjusting the large arm are positioned in the ceiling, and the schematic diagram of the interior of the ceiling is shown in fig. 1.
When an operator stands in front of the working arm operating rod, the moving position of the working arm is observed and adjusted in real time, and the engine accelerator pedal is arranged on the right side of the driving seat, so that the sideways operation at the moment is very inconvenient for a single operator. The existing solution is to install a hand throttle knob on the right side of the operating lever of the working arm to raise the engine speed. The solutions adopted by the above technologies cannot automatically detect the position of the person, the running state of the vehicle, the on state of the high-voltage power supply and the like. When an operator sits on the seat and runs the vehicle, if the working arm is required to move quickly, the rotation speed of the engine is required to be increased at the moment, the manual accelerator knob is difficult to control the flow of hydraulic oil, and if the operator operates the accelerator knob at the moment, the working arm collision in the running process of the vehicle, which is caused by too high rotation speed increase, is easy to occur. And the hand throttle does not have an automatic reset function and needs to be manually closed, once an operator restarts the engine or drives the vehicle in an unrereset state, dangerous accidents can occur to the vehicle due to the fact that the rotating speed of the engine is too high. Meanwhile, the engine speed is increased to be automatically disabled after the high-voltage power is connected to the vehicle, but the technical scheme cannot be realized.
