Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of gas extraction and prevention equipment, and relates to a high-power automatic directional drilling machine, in particular to a progressive angle adjusting device with main shaft inclination angle locking function and a directional drilling machine. BACKGROUND

[0002] At present, the coal mine underground tunnel drilling machine is mainly used for gas pre-extraction and treatment to ensure the safe and efficient production of coal mines. Under the same coal seam original pressure, coal seam permeability and the same drilling extraction negative pressure, increasing the drilling diameter and drilling depth can greatly improve the coal seam gas extraction efficiency. The ordinary rotary drilling machine is only suitable for drilling design with shallow depth because the drilling trajectory is uncontrollable. The directional large-diameter long drilling has the advantages of large aperture, accurate positioning, deep hole, controllable trajectory and high efficiency, and is widely used in high-gas and outburst mines.

[0003] The directional drilling machine is a special equipment for directional large-diameter long drilling construction. The traditional directional drilling machine mainly relies on manual installation and removal of drilling tools, which not only increases the labor intensity of the on-site workers and reduces the drilling construction efficiency, but also has great safety hazards. With the increase of the specifications of the matched drilling tools, it is difficult for manpower to complete the installation and removal of the drilling tools, and the mechanized replacement of manpower and the automation of labor reduction technology are carried out. The application of high-power automatic directional drilling machine has become a trend. In order to realize the automatic function, the high-power directional drilling machine needs to integrate modules such as rod bin, rod adding manipulator, buckle remover, controller and sensor. The integration of these modules will greatly increase the size and weight of the high-power drilling machine, limiting its application in the narrow space of the coal mine underground. In order to reduce the height size of the high-power automatic directional drilling machine, the height of the drilling angle adjusting device needs to be designed as low as possible. However, due to the integration of the automatic function, the weight of the drilling machine host is greatly increased. The too low angle adjusting device is not enough to generate enough upward component force to support the host, and it cannot ensure that the host has a large enough angle and height adjusting range, which limits the application of the drilling machine.

[0073] As a specific scheme of this embodiment, displacement sensors 11 and inclination sensors 12 are arranged on the feeding device 6.

[0074] In this embodiment, the relationship between the displacement measured by the displacement sensor 11 and the drilling rig horizontal opening height is as follows: "drilling rig horizontal opening height" is "displacement measured by the displacement sensor 11 + distance from the displacement sensor installation position to the drilling rig power head main shaft axis + distance from the tracked vehicle body to the ground", that is, the opening height is "displacement of the displacement sensor + fixed value", which does not change after the structure is designed.

When the drilling rig needs to be adjusted to the required design opening height, the displacement of the sensor should be the opening height minus the fixed value. During the angle adjustment process, the displacement sensor displacement first reaches the requirement, at which time the displacement sensor is in a tilted state and does not meet the opening height requirement. Subsequently, the rear end cylinder of the feeding device is actuated to adjust the rear end of the feeding device to the same height as the front end, that is, the feeding device is in a horizontal position, at which time the displacement sensor is in a vertical state, that is, the horizontal opening height of the drilling rig can be considered to be reached.

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

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

[0077] The feeding device 6, the drilling rig power head 7 and the gripper 8 are all in a horizontal position. The drill pipe 14 and the tool string are lowered into the drill hole 13 through the drill pipe adding device to perform directional drilling rig horizontal construction.

[0078] Second, adjust the opening height and perform high-hole construction (as shown in Figure 7 ):

[0079] High-pressure oil is input into the front multi-stage angle adjustment cylinder 205 and the front inclined strut angle adjustment cylinder 402 to make the front end of the feeding device 6 rise or fall to the design height. Subsequently, high-pressure oil is input into the rear multi-stage angle adjustment cylinder 105 and the rear inclined strut angle adjustment cylinder 302 to make the longitudinal rear part of the feeding device 6 rise or fall to the design height. When the drilling rig reaches the preset opening height, high-pressure oil drives the cross beam cylinder 10404 to drive the liquid-driven chuck 10405 to clamp the front inclined strut column 202 and the rear inclined strut column 102. After the position of the feeding device 6 is adjusted, the drill pipe 14 and the tool string are lowered into the drill hole 13 through the drill pipe adding device to perform directional drilling rig high-hole construction.

[0080] Third, adjust the elevation angle and perform large-elevation-angle construction (as shown in Figure 8 ):

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

[0082] Thirdly, the depression angle is adjusted to perform large-depression-angle construction (as shown in the figure): Figure 9

[0083] The high pressure oil is input into the rear multi-stage angle adjusting oil cylinder 105 and the rear diagonal brace angle adjusting oil cylinder 302, and the rear multi-stage angle adjusting oil cylinder 105 provides sufficient driving force to drive the rear end of the feeding device 6 to rise to a preset depression angle. When the rig is in the initial position and the preset depression angle is at a large angle, the position of the rear end of the feeding device 6 is first adjusted by the rear multi-stage angle adjusting oil cylinder 105 until the rear multi-stage angle adjusting oil cylinder 105 stops after reaching the maximum stroke, and then the rear diagonal brace angle adjusting oil cylinder 302 performs progressive angle adjustment to drive the rear end of the feeding device 6 to rise and drive the rear beam assembly 104, the rear multi-stage angle adjusting oil cylinder 105, and the rear multi-stage angle adjusting oil cylinder mounting 103 to move upward along the rear diagonal brace upright column 102 until the rig reaches the preset depression angle. If the rig is not in the initial position, the high pressure oil is input into the rear multi-stage angle adjusting oil cylinder 105 and the rear diagonal brace angle adjusting oil cylinder 302 to drive the rear end of the feeding device 6 to rise or fall until the rig reaches the preset depression angle; when the rig reaches the preset depression angle, the high pressure oil drives the beam oil cylinder 10404 to drive the hydraulic drive chuck 10405 to clamp the rear diagonal brace upright column 102. After the position of the feeding device 6 is adjusted, the drill pipe 14 and the tool string are lowered into the borehole 13 through the drill pipe adding device to perform the large-depression-angle construction of the directional drilling rig.​
