Description

Technical Field

[0001] The invention belongs to the technical field of gas extraction and prevention equipment, and relates to a high-power automatic directional drilling rig, and in particular to a progressive angle adjustment device with a main shaft inclination locking function and a directional drilling rig. Background Art

[0002] At present, underground tunnel drilling rigs are mainly used for gas pre-extraction and treatment to ensure safe and efficient production of coal mines. Under the same coal seam original pressure, coal seam permeability and the same borehole extraction negative pressure, increasing the borehole diameter and borehole depth can greatly improve the coal seam gas extraction efficiency. Ordinary rotary drilling rigs are only suitable for occasions with shallow borehole depths because the drilling trajectory is uncontrollable. Directional large-diameter long drilling has many advantages such as large aperture, accurate positioning, deep hole, controllable trajectory and high efficiency, and is widely used in high-gas and protruding mines.

[0003] Directional drilling rigs are special equipment for directional large-diameter long-hole construction. Traditional directional drilling rigs mainly rely on manual loading and unloading of drilling tools, which not only increases the labor intensity of on-site workers and reduces the efficiency of drilling rig construction, but also has great safety hazards. With the increase in the specifications of supporting drilling tools, it is difficult for manpower to complete the loading and unloading of drilling tools, and the development of special actions such as mechanized replacement and automated reduction of manpower to strengthen science and technology, the application of high-power automatic directional drilling rigs has become a trend. In order to realize the automatic function, high-power directional drilling rigs need to integrate modules such as rod bins, rod adding manipulators, shackles, controllers, sensors, etc. The integration of these modules will greatly increase the size and weight of high-power drilling rigs, limiting their application in narrow spaces underground in coal mines. In order to reduce the height of high-power automatic directional drilling rigs, the height of the drilling rig angle adjustment device needs to be designed as low as possible, but the weight of the drilling rig host is greatly increased due to the integration of automatic functions. The angle adjustment device that is too low is not enough to generate enough upward force to support the host, and it cannot ensure that the host has a large enough angle adjustment and height adjustment range, which limits the application of drilling rigs.

[0072] As a specific solution of this embodiment, Figure 6 As shown, a crane 10 is installed on the crawler body 5 of the drilling rig.

[0073] As a specific solution of this embodiment, the displacement sensor 11 and the inclination sensor 12 on the feeding device 6. The inclination sensor 12 is used to measure the inclination angle of the main shaft of the drilling rig, including the elevation angle and the depression angle; the displacement sensor 11 is used to detect the displacement of the front end of the feeding device 6 relative to the crawler body 5 of the drilling rig, and then obtain the horizontal opening height of the drilling rig.

[0074] In this embodiment, the relationship between the displacement measured by the displacement sensor 11 and the horizontal hole height of the drilling rig is as follows: "The horizontal hole height of the drilling rig" is "the displacement measured by the displacement sensor 11 + the distance from the installation position of the displacement sensor to the main shaft axis of the drilling rig power head + the distance from the crawler body to the ground", that is, the hole height is "the displacement of the displacement sensor + the fixed value", and the fixed value will not change after the structure is designed. The displacement sensor 11 is installed at the front end of the feed device. When the drilling rig is to be adjusted to the required designed hole height, the displacement of the sensor should be the hole height minus the fixed value. During the angle adjustment process, the displacement of the displacement sensor first reaches the requirement. At this time, the displacement sensor should be in an inclined state and does not meet the hole height requirement. Then the rear end cylinder of the feed device is actuated to adjust the rear end of the feed device to the same height as the front end, that is, the feed device is in a horizontal position. At this time, the displacement sensor is in a vertical state, which can be considered as the horizontal hole height of the drilling rig.

[0075] The working process of the directional drilling rig with the progressive angle adjustment device having the spindle inclination locking function of the present invention is as follows:

[0076] First, horizontal construction (such as Figure 6 shown):

[0077] The feed device 6, the drilling rig power head 7, and the clamp 8 are all in a horizontal position, and the drill rod 14 and the tool string are lowered into the borehole 13 through the drill rod adding device to perform horizontal construction of the directional drilling rig.

[0078] Second, adjust the opening height and carry out high-position hole construction (such as Figure 7 shown):

[0079] The high-pressure oil is input into the front multi-stage angle adjustment cylinder 205 and the front diagonal support angle adjustment cylinder 402, so that the front end of the feed device 6 rises or falls to the designed height; then the high-pressure oil enters the rear multi-stage angle adjustment cylinder 105 and the rear diagonal support angle adjustment cylinder 302, so that the longitudinal rear part of the feed device 6 rises or falls to the designed height. When the drilling rig reaches the preset hole opening height, the high-pressure oil drives the crossbeam cylinder 10404 to drive the liquid-driven chuck 10405 to clamp the front diagonal support column 202 and the rear diagonal support column 102. After the position of the feed device 6 is adjusted, the drill rod 14 and the tool string are lowered into the borehole 13 through the drill rod adding device to carry out the high-position hole construction of the directional drilling rig.

[0080] Third, adjust the elevation angle to carry out large elevation angle construction (such as Figure 8 shown):

[0081] High-pressure oil is input into the front multi-stage angle adjustment cylinder 205 and the front diagonal support angle adjustment cylinder 402. The front multi-stage angle adjustment cylinder 205 provides sufficient driving force to make the front end of the feed device 6 rise to the preset elevation angle. When the drilling rig is at the initial position and the preset elevation angle is at a larger angle, the front multi-stage angle adjustment cylinder 205 is used to adjust the position of the front end of the feed device 6 until the front multi-stage angle adjustment cylinder 205 stops after reaching the maximum stroke, and then the front diagonal support angle adjustment cylinder 402 performs progressive angle adjustment, driving the front end of the feed device 6 to rise and drive the front crossbeam assembly 204, the front multi-stage angle adjustment cylinder 205, and the front multi-stage angle adjustment cylinder mounting member 203 to move upward along the front diagonal support column 202 until the drilling rig reaches the preset elevation angle. If the drilling rig is not in the initial position, the high-pressure oil enters the front multi-stage angle adjustment cylinder 205 and the front diagonal support assembly 4, driving the front end of the feed device 6 to rise or fall until the drilling rig reaches the preset elevation angle; when the drilling rig reaches the preset elevation angle, the high-pressure oil drives the crossbeam cylinder 10404 to drive the liquid-driven chuck 10405 to clamp the front diagonal support column 202. After the position of the feed device 6 is adjusted, the drill rod 14 and the tool string are lowered into the borehole 13 through the drill rod adding device to perform the directional drilling rig high elevation construction.

[0082] Third, adjust the depression angle and carry out large depression angle construction (such as Fig. 9 shown):

[0083] High-pressure oil is input into the rear multi-stage angle adjustment cylinder 105 and the rear diagonal support angle adjustment cylinder 302, and the rear multi-stage angle adjustment cylinder 105 provides sufficient driving force to drive the rear end of the feed device 6 to rise to the preset depression angle. When the drilling rig is at the initial position and the preset depression angle is at a larger angle, the rear multi-stage angle adjustment cylinder 105 is used to adjust the position of the rear end of the feed device 6 until the rear multi-stage angle adjustment cylinder 105 reaches the maximum stroke and stops, and then the rear diagonal support angle adjustment cylinder 302 performs progressive angle adjustment, drives the rear end of the feed device 6 to rise and drives the rear crossbeam assembly 104, the rear multi-stage angle adjustment cylinder 105, and the rear multi-stage angle adjustment cylinder mounting member 103 to move upward along the rear diagonal support column 102 until the drilling rig reaches the preset depression angle. If the drilling rig is not in the initial position, the high-pressure oil enters the rear multi-stage angle adjustment cylinder 105 and the rear diagonal support angle adjustment cylinder 302, driving the rear end of the feed device 6 to rise or fall until the drilling rig reaches the preset depression angle; when the drilling rig reaches the preset depression angle, the high-pressure oil drives the crossbeam cylinder 10404 to drive the liquid-driven chuck 10405 to clamp the rear diagonal support column 102. After the position of the feed device 6 is adjusted, the drill rod 14 and the tool string are lowered into the borehole 13 through the drill rod adding device to perform the directional drilling rig high depression angle construction.
