Description
Technical Field
The invention relates to the technical field related to core drilling machines, in particular to a high-stability chassis for a core drilling machine.
Background
The core drilling machine is a core drilling device, and is mainly used for general investigation and exploration of metal and nonmetal solid mineral products, and can also be used for engineering geological exploration, hydrogeological investigation, general investigation and exploration of oil and gas fields, well drilling and the like.
With the economic development of industrial society, the demands of various countries on mineral resources are larger and larger, the global mineral exploration market starts to go out of the valley at the end of the last century and goes up year by year, the mineral exploration investment is continuously increased, the demands on drilling equipment are continuously increased, a core drill is a key equipment for geological exploration, and the market demand is also continuously increased along with the mineral exploration investment.
The core drilling machine consists of a rotary mechanism, a feeding mechanism, a lifting mechanism, a transmission mechanism, an operating device, a machine base and other basic parts. Some core drills may also be equipped with control gauges or other accessory devices, due to the different types of drills.
The rotary mechanism of the drilling machine is called a gyrator and is used for driving the drilling tool to rotate so as to realize continuous rock breaking of the drilling bit. The gyrator of the core drilling machine has three types of vertical shaft type, rotary table type and movable type, and the classification of the core drilling machine is that the core drilling machine is sourced.
The lifting mechanism is used to lift a drill, casing or other item. Most drilling rigs are specially equipped with a lifting mechanism, commonly referred to as a "lift", while some drilling rigs are not equipped with a lifting mechanism, such as in a mobile gyratory rig, the function of the lift is achieved by the cooperation of a power head and a feed mechanism.
The feeding mechanism is used for adjusting and maintaining the axial load on the drill bit at the bottom of the hole, feeding the drilling tool according to the drilling speed of the drill bit, and maintaining the drill bit to continuously drill holes.
The transmission mechanism is used for transmitting power from the power machine of the drilling machine to each working mechanism of the drilling machine. The power transmission mode of the drilling machine is three types of organic transmission, semi-hydraulic transmission and full-hydraulic transmission.
The operating device is used for distributing power, adjusting the movement speed of each working mechanism of the drilling machine and changing the movement direction and form of the working mechanism. The operating mechanisms of mechanically driven drills are typically arranged together with the associated components, whereas the operating mechanisms of hydraulically driven drills are often arranged together in separate components, called consoles.
Finally, the revolving mechanism, the feeding mechanism, the lifting mechanism, the transmission mechanism and the operating device are fixedly arranged on the installation chassis through the machine base, and in order to facilitate movement, a trailer frame such as a caterpillar chassis or a wheel chassis is usually arranged under the installation chassis, and the structure is also an integral structure.
At present, the core drilling machine still has a plurality of problems in the use process, the angle deviation frequently occurs during sampling, and for survey drilling with depth deeper than hundred meters, the drilling angle deviation is frequently generated, so that the bending angle of a pore canal is overlarge, the sampling precision is insufficient and cannot meet the sampling standard specified by the country, the repeated sampling precision cannot be ensured, and the main internal factors for generating the problems are as follows: 1. the drilling machine is not in a horizontal position, or the construction site is not leveled or compacted, and irregular sedimentation occurs in the drilling process; 2. the drilling platform base is unstable and is not in a horizontal state, and the drilling machine bracket is unevenly deformed; 3. the drill rod is bent, and the joint loosens, so that the drill bit is too large in shaking amplitude.
The problem of rig horizontal position and construction site can be realized through landing leg regulation, flattening and compaction site, but the vibrations that the rig during operation produced also can make the irregular settlement condition aggravated in stabilizer blade position, the deformation of rig support receives the vibrations factor influence of transport and during operation equally, the vibrations that the rig during the transport produced and the vibrations that the rig during operation influence the stability of chassis, can make the fixed screw of rig of installation produce not hard up, lead to the part joint to connect not hard up, so the rig during operation can lead to the drilling rod crooked, cause the drill bit to rock the too big and drilling deflection of range, be difficult to reach the sampling standard. At present, the damping scheme of the drilling machine is based on damping of drilling bit of the drilling machine, for example, patent CN219299220U discloses a damping device of the drilling machine, and the damping device has a certain effect on the stability of the drilling bit by buffering and damping the vibration of the drilling bit of the drilling machine, but the overall damping effect is poor, and the damping effect on other positions is not good.
