Embodiment Construction

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

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

[0026] Such as 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. The throttle knob, operating handle, engine speed sensor, key switch, and other signal input devices are connected to the input terminal of the controller. There are at least two engine gears on the throttle knob, and each engine gear correspond...

Abstract

The invention discloses an engine gear position control system, comprising a controller, an accelerator knob, and an operating handle. The accelerator knob is provided with at least two engine gear positions, and each engine gear position corresponds to a different engine speed and power output. There is a full power output button for controlling the full power output of the engine; when the full power output button is pressed, the controller controls the full power output of the engine, otherwise, the corresponding engine speed output of the engine is controlled according to the engine gear of the throttle knob. The invention also provides a rotary drilling machine. The invention can quickly apply to harsh working conditions such as sudden increase in the load of the rotary drilling rig in a short time, prolongs the service life of the engine, and improves the construction efficiency; the engine start protection module can effectively prevent the machine operator from starting the engine in an irregular manner; the calibration module realizes one key The calibration function makes the calibration operation simple and convenient for the machine operator.

Description

technical field [0001] The invention relates to the field of engineering 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 building foundation engineering. With different drilling tools, it is suitable for hole forming operations of short screw, rotary bucket and rock formation. For dry and hard clay, the dry rotary excavation method of stabilizing liquid retaining wall is not required. The general covering layer adopts the wet rotary excavating method of static mud retaining wall. It is widely used in foundation drilling and pouring of railways, highway bridges, municipal construction, high-rise buildings, etc. 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 combining the engine and the hydraulic transmission. Due to the harsh working...
