Description
Technical Field
The invention relates to an intelligent control system with a main oil way pressure regulating and temperature controlling function for a rotary drilling rig, and belongs to the field of piling machinery.
Background
The rotary drilling rig is a hydraulic driving device, soil is cut into a drilling bucket by controlling rotation and pressurization of a power head to drive rotation and pressurization of a drill rod drilling bucket, then the drilling bucket is taken out of a hole by lifting of a main hoisting steel wire rope, the drilling bucket is taken to a position deviated from the hole by rotary action of the rotary drilling rig, and soil is discharged out of the hole by opening a drilling bucket door through a soil throwing disc of the power head.
The temperature of hydraulic oil of the rotary drilling rig is between 30 ℃ and 80 ℃ under the normal condition, if the temperature of the hydraulic oil is too low, the viscosity of the hydraulic oil is high, the fluidity is poor, the resistance is high, the working efficiency is low, and if the temperature of the hydraulic oil is lower than 20 ℃, a hydraulic motor, a valve, a pipeline and the like are easily damaged by sharp turning. If the oil temperature of a hydraulic system is too high, the viscosity of hydraulic oil is reduced, leakage is easily caused, the efficiency is reduced, the strength of a smooth oil film is reduced, the abrasion of machinery is accelerated, carbide and silt are generated, the oil is oxidized to accelerate the oil quality deterioration, and an oil seal, a high-pressure rubber pipe are too early. The main reasons causing the too high oil temperature of the hydraulic oil of the rotary drilling rig are that the heat generation is too fast and the heat dissipation is too slow, the temperature rise is directly caused by the energy loss of throttling and overflowing of a hydraulic system, and meanwhile, the oil inlet pipeline and the hydraulic oil tank of the hydraulic pump are not tightly sealed, an oil inlet filter element is blocked, the pipeline of the hydraulic system is not smooth, and the internal leakage of the hydraulic pump can enable the hydraulic oil to generate a large amount of heat, so that the temperature of the hydraulic oil is rapidly.
In cold winter, when the oil temperature is too low, warm-up operation is carried out, an engine is started, after the engine rotates for 10-20min (or longer) in an idle-load mode, the hydraulic rotary drilling rig increases the rotating speed of the engine through a medium-speed accelerator, a handle is operated to enable any one of working devices to move to the maximum, and the temperature of hydraulic oil is kept for 5-10min (or longer) to be increased through overflow.
Some rotary drilling rigs in the market at present are all provided with oil temperature cooling devices for reducing the oil temperature of a hydraulic system, and the working principle of the devices is that after the rotary drilling rigs are started, cooling fans run at full speed. However, this has three disadvantages: 1. in cold winter, the system temperature and the environment temperature are very low when the construction is started, and the full-speed operation of a cooling fan is not needed for cooling at all; 2. during normal construction, the cooling fan is not required to run at full speed in many times, and the operation not only increases the energy loss of construction equipment, but also is not the optimal temperature (about 60 ℃) of a hydraulic system; 3. the fan blades which run at full speed for a long time are easy to fatigue, and the service life of the oil temperature cooling device is shortened.
In the actual construction process, the geological conditions are different due to different hole depths. Meanwhile, different apertures require different torques, pressures, lifting forces and pulling forces on the drill rod of the power head. Particularly, when the construction is carried out under geological conditions such as rock strata, frozen soil layers, clay layers and the like, instantaneous high pressure is easily generated by a hydraulic system during the construction, and the instantaneous high pressure causes fatal damage to the overall performance of equipment, particularly components and parts of the hydraulic system.
