Problems solved by technology

General operators often increase the engine speed to the maximum when operating the rotary drilling rig, but the actual power of the engine is limited, and a lot of power is wasted
[0003] At present, the number of foundation constructions using rotary drilling rigs in China is extremely large, and the unscientific methods of use account for the majority, resulting in serious energy waste. Diesel is a non-renewable energy source. It is necessary to use new technologies to reduce energy consumption.

Abstract

The invention discloses an engine rotating speed control device of a rotary drilling rig. The engine rotating speed control device is provided with an automatic / manual button and a parking button and is connected with an A / D (analog / digital) converter and a servo system, the A / D converter is connected with a plurality of sensors, a speed sensor is fixedly mounted on a diesel engine, and an accelerator position sensor and the speed sensor are connected with the A / D converter. A working unit of the engine rotating speed control device is capable of controlling the rotating speed of the diesel engine by means of controlling an accelerator motor via a program.

Description

technical field [0001] The invention belongs to an engine speed control device, in particular to a rotary drilling rig engine speed control device. Background technique [0002] Rotary drilling rigs are widely used in various constructions such as high-rise buildings, highways, bridges, railways, ports, tunnels, and subways. become related. For example, the working states include driving, luffing, rotary excavation, soil throwing, slewing, main and auxiliary winch lifting, oil cylinder pressurization, etc. The power required for each working state is different. General operators often increase the engine speed to the maximum when operating the rotary drilling rig, but the actual power of the engine is limited, and a lot of power is wasted. [0003] At present, the number of foundation constructions using rotary drilling rigs in China is extremely large, and most of them are used unscientifically, resulting in serious energy waste. Diesel is a non-renewable energy source, s...
