Embodiment Construction

[0024] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0025] like Figures 1 to 3 As shown, in a preferred engine gear control system of the present invention, the output shaft of the engine is directly connected with the hydraulic pump, and the hydraulic pump provides hydraulic oil power to the hydraulic system of the rotary drilling rig.

[0026] like figure 1 As shown, the engine gear control system includes a display and a controller, the throttle motor adjusts the throttle opening of the engine, and the throttle knob, operating handle, engine speed sensor, key switch, and other signal input devices are connected to the input end of the controller. There are at least two engine gears on the throttle knob. Each ...

Abstract

The invention discloses an engine gear control system comprising a controller, a throttle knob, and an operating handle. The throttle knob is provided with at least two engine gears which correspond to different engine speeds and power outputs. The operating handle is provided with a full-power output button used for controlling full-power output of an engine. When the full-power output button is pressed, the controller makes the engine perform output at full power, or the engine performs output at a corresponding engine speed according to the engine gear of the throttle knob. The invention further provides a rotary drilling rig. The engine gear control system can quickly adapt to sudden load increase of the rotary drilling rig in a short time and other bad working conditions, the service life of engines is prolonged, and the efficiency of construction is improved. An engine starting protection module can effectively prevent a machinist from starting an engine improperly. A calibration module achieves a one-button calibration function, makes calibration operation simple, and is convenient for machinist to operate.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an engine gear control system and a rotary drilling rig. Background technique [0002] Rotary drilling rig is a kind of construction machine suitable for hole forming in construction foundation engineering. With different drilling tools, it is suitable for hole forming operation of short screw, rotary bucket and rock formation. For dry and hard clay, the dry rotary excavation method without stabilizing liquid retaining wall can be used. The general covering layer adopts the wet rotary excavation method of static mud retaining wall. It is widely used in railways, highways, bridges, municipal construction, high-rise buildings and other places. Pile works. [0003] The power system of the rotary drilling rig is directly connected by the engine and the hydraulic pump, which is a unity of the engine and the hydraulic transmission. Due to the harsh working environment of the rot...
