Description

Technical Field

[0001] The utility model relates to the field of drilling, in particular to a gripper fixing seat for a kilometer directional drilling rig and an integrated on - ground and underground kilometer directional drilling rig. Background Art

[0002] Drilling is a general term for technical activities such as geological exploration, resource development, mine underground engineering, engineering geological investigation, building foundation reinforcement, and geological disaster control using drilling rigs, drill tools, and a complete set of technological measures. With the continuous expansion of the construction field and the increasing construction requirements, drilling technology has developed from conventional drilling technology to directional drilling technology. By means of artificial deviation, the drill hole is extended along a predetermined trajectory to reach the predetermined target. Drilling methods are divided into surface drilling technology and underground drilling technology according to the construction space. Surface drilling technology is not restricted by space and can use large vehicle - mounted drilling rigs or derricks as the hoisting system to lift and lower drill tools, lower casing, and control the bit pressure and feed rate, etc. Additionally, a mud circulation system is equipped to wash and discharge cuttings. Due to space limitations, underground drilling technology mostly uses split - type small drilling rigs, that is, separating the pump station, the main machine, and the operation console to facilitate relocation and transportation in narrow roadways. With the modernization of roadway excavation, large - section roadways can accommodate the transportation of integral crawler drilling rigs.

[0003] With the progress of technology, both mine underground drilling rigs and surface engineering drilling rigs have made great progress and formed a series of mature equipment respectively. However, with the continuous subdivision of the construction field, drilling rigs are developing towards diversification, specialization, and refinement, but inevitably resulting in the problem of poor applicability of drilling rigs. How to coordinate the contradiction among the professionalism, refinement, and adaptability of drilling rigs is one of the difficult problems in the current design of drilling rigs. For example, since coal mine underground drilling rigs and surface engineering drilling rigs belong to different categories, there are differences in design parameters, structures, and construction environments. Through market research, it is found that basically all coal mine underground drilling rigs are difficult to be applied to surface drilling construction (the power head cannot open the hole mouth, and the body inclination angle cannot be adjusted negatively at a large angle). Among common surface drilling rigs, water well drilling rigs cover a large area, the control mechanism is complex, it is difficult to miniaturize, and basically it is difficult to apply through - cable drill pipes, and directional construction is restricted; vehicle - mounted drilling rigs are equipped with top drives and have large power, but they are costly and the drill tools are heavy; oil drilling rigs are relatively large in volume, and the deepest vertical drilling can reach more than 5000m, but the horizontal drilling length is short. In the prior art, the opening angle of kilometer directional drilling rigs is - 10° to + 20°, the negative angle adjustable range of the body is small, and large - angle negative construction mainly relies on artificial deviation. Although it is widely used in coal mine underground, it cannot achieve vertical drilling and has great inadaptability in surface construction.

[0004] In order to realize an integrated on - ground and underground drilling rig, how to design a detachable component connecting piece suitable for two working conditions is an urgent problem to be solved. Summary of the Utility Model

[0005] In view of this, the present utility model proposes a gripper fixing seat for a kilometer directional drilling rig and an above-ground and underground integrated kilometer directional drilling rig using the gripper fixing seat, aiming to solve the problems existing in the prior art.

[0018] A chassis assembly is provided below the mast;

[0019] The gripper fixing seat for a kilometer directional drilling rig for mounting an above-ground angle adjusting oil cylinder or a downhole angle adjusting oil cylinder is provided on the mast.

[0020] On the basis of the above solution, an articulated position for fixing the ground guiding mechanism during ground operation is provided at the end of the chassis assembly far from the connection end with the mast;

[0021] The other end of the ground guiding mechanism is articulated with the upper section of the mast for ground operation;

[0022] The upper section of the mast is arranged at the upper end of the mast.

[0023] On the basis of the above solution, it further includes: a front slewing center provided on the chassis assembly and serving as the rotation center of the mast during ground operation.

[0024] On the basis of the above solution, the ground guiding mechanism and the front slewing center cooperate with each other to control the lifting height of the mast.

[0025] On the basis of the above solution, it further includes: a rear slewing center provided on the chassis assembly and serving as the rotation center of the mast during underground operation.

[0026] On the basis of the above solution, it further includes: an underground guiding mechanism provided on the chassis assembly and cooperating with the rear slewing center and the angle adjustment cylinder for underground use to adjust the elevation angle of the mast.

[0027] The holder fixing seat for the kilometer directional drill of the present utility model can be simultaneously connected to the fuselage angle adjustment oil cylinder to increase the angle adjustment range, which are the downhole positive angle adjustment oil cylinder of 0-20° for downhole use and the ground negative angle adjustment oil cylinder of 0--90° for ground use; the holder fixing seat can be installed with a drill pipe clamping structure, suitable for different working conditions, a hydraulic chuck is installed during downhole directional drilling, and a hydraulic wooden horse holder is installed during ground drilling.

The side shift of the power head is controlled by a hydraulic oil cylinder to let the opening, and the feed oil cylinder is redesigned. On the basis of basically ensuring the original propulsion force, the pulling force is increased to 620 kN, greatly improving the drilling efficiency. The switching between the two working states of directional drilling and core exploration can be completed by replacing individual parts of the power head. The rig is applicable to a variety of working conditions and can be used for engineering construction such as directional drilling, core exploration, rescue holes, and life-saving holes.

[0054] As a specific embodiment, the drill pipe clamping structure includes:

[0056] The ground drilling connecting plate 6-3 is provided with a first fixing hole 6-31 for connecting the free end of the ground angle adjusting oil cylinder 9-1.

[0057] The downhole drilling connecting plate 6-4 is provided with a second fixing hole 6-41 for connecting the downhole angle adjusting oil cylinder 9-2 during underground operation.

[0058] During ground operation, the second fixing hole 6-41 is not connected to other structures.

[0059] The clamp holder fixed seat 6 can be connected to two fuselage angle adjusting oil cylinders to increase the angle adjustment range, namely, the downhole positive angle downhole angle adjusting oil cylinder 9-2 with an angle range of 0 to 20° (the connection position is shown in Figure 8 as shown) or the ground negative angle ground angle adjusting oil cylinder 9-1 with an angle range of 0 to -90° (the connection position is shown in Figure 7 as shown); the clamp holder fixed seat 6 can be installed with a drill pipe clamping structure (wooden horse clamp 10-1 or chuck 10-2) to suit different working conditions. The hydraulic chuck 10-2 is installed during downhole directional drilling, and the hydraulic wooden horse clamp 10-1 is installed during ground drilling.

[0060] Wherein, an upper section 1-2 of the mast and a forehead 1-1 are arranged at the upper end of the mast 1, and the upper section 1-2 of the mast is detachable.

[0061] As Figure 1 shown, as a specific embodiment of the power head assembly 5, the power head assembly 5 includes a feeding mechanism 5-1 arranged inside the mast 1, a power head support seat 5-2 arranged on the cylinder barrel of the feeding mechanism 5-1, and a power head 5-3 arranged on the power head support seat 5-2. As Figure 8As shown in the figure, the feeding mechanism 5-1 includes a feeding oil cylinder and a feeding mechanism connecting seat 5-1-1. When the feeding mechanism 5-1 works, the cylinder barrel of the feeding oil cylinder expands and contracts, driving the power head support seat 5-2 and the power head 5-3 thereon to move synchronously. The detachable mast 1 is connected to the feeding mechanism 5-1. In the ground drilling working state, the mast is installed to improve the working efficiency of lifting and lowering drill pipes, and multiple drill pipes can be lifted at one time; in the downhole drilling working state, due to the limitation of downhole space, the mast 1 can be disassembled from the drill rig.

[0062] Specifically, as a specific implementation manner of the feeding mechanism 5-1, a single-rod double-acting cylinder is selected.

[0063] In the prior art, for a 2*125 cylinder diameter double-rod double-acting cylinder, the propelling force: F = 2PA = 2×32π / 4(125² - 90²)

[0064] = 370kN, where P is the pressure and A is the area;

[0065] As a specific implementation manner of the single-rod double-acting cylinder, for a 150 cylinder diameter single-rod double-acting cylinder, the propelling force: F = PA = 35×π / 4(150² - 100²) = 350kN, where P is the pressure and A is the area.

[0066] As Figure 3 shown in the figure, as a specific implementation manner of the power head 5-3, the power head 5-3 includes:

[0067] A motor 5-3-1 for providing power;

[0068] A planetary gear train provided on the power head housing 5-3-10 for performing the first-stage deceleration on the power output by the motor 5-3-1;

[0069] A double gear 5-3-6 provided on the planetary gear train for performing the second-stage deceleration on the power output by the motor 5-3-1;

[0070] A large gear 5-3-7 provided on the double gear 5-3-6 and meshing with the double gear 5-3-6 for performing the third-stage deceleration on the power output by the motor 5-3-1;

[0071] And an output shaft 5-3-8 provided on the power head housing 5-3-10 for meshing with the large gear 5-3-7 to perform power output. Wherein, the planetary gear train includes an internal gear ring 5-3-4, a planetary gear 5-3-9, a sun gear 5-3-3 and a planetary gear carrier 5-3-5. The internal gear ring 5-3-4 is fixed on the power head housing 5-3-10, and a small gear is provided on the planetary gear carrier 5-3-5, and the small gear meshes with the double gear 5-3-6 for performing the second-stage deceleration.

[0072] As Figure 4 shown, as a specific embodiment of the power head 5-3, it further includes: a power head housing 5-3-10, an output shaft 5-3-8 provided on the power head housing 5-3-10, and a large gear 5-3-7 provided on the output shaft 5-3-8 and meshing with a double gear 5-3-6 for third-stage deceleration.

[0073] To facilitate the installation of the motor 5-3-1, it further includes: a motor support 5-3-2 provided on the internal gear ring 5-3-4 for installing the motor 5-3-1.

[0074] As Figure 4 shown, to enable the power head 5-3 to move laterally to clear the opening (the opening is the opening of the drilling hole in the drilling construction), and to facilitate the extraction of the core barrel in working conditions such as wireline coring, it further includes: a lateral movement oil cylinder 5-3-11 provided below the power head housing 5-3-10.

[0075] During installation, the motor 5-3-1 is bolted to the motor support 5-3-2, the motor support 5-3-2 is bolted to the internal gear ring 5-3-4, the internal gear ring 5-3-4, the planet gears 5-3-9, the sun gear 5-3-3, and the planet gear carrier 5-3-5 together form a planetary gear train. The motor output shaft 5-3-8 meshes with the sun gear 5-3-3. The power output by the motor 5-3-1 is decelerated by the first stage through the planetary gear train. The internal gear ring 5-3-4 is fixed on the power head housing 5-3-10. A small gear is provided on the planet gear carrier 5-3-5, and the small gear meshes with the double gear 5-3-6 for second-stage deceleration. The double gear 5-3-6 meshes with the large gear 5-3-7 for third-stage deceleration. An external spline is provided on the output shaft 5-3-8 and meshes with the internal spline of the large gear 5-3-7 to output power.

[0076] In summary, through the above transmission route, three-stage deceleration is formed, and two motors in the original design scheme can be optimized into one motor, and the maximum output torque of 25000 N·m remains unchanged.

[0077] Embodiment 2

[0078] Based on the device in Embodiment 1, the present application provides a specific embodiment of a kilometer directional drill for surface drilling.

[0079] As Figure 1 shown, as a specific embodiment of the surface drilling of the drill, when the drill is drilling on the ground, an anchoring oil cylinder 8 for providing power to the drill pipe is provided below the wooden horse gripper 10-1.

[0080] When performing vertical drilling, the gripper not only has to bear the gravity of the entire drill string but also needs to provide sufficient make-up and break-out torque. The grippers in the prior art do not provide clamping force during negative large inclination angle and vertical hole drilling. Therefore, it is necessary to re-select the gripper. The original gripper is selected for horizontal hole or upward hole drilling, and the hydraulic wooden horse gripper 10-1 is selected for negative angle drilling. The wooden horse gripper 10-1 has the functions of self-locking clamping and automatic compensation. The anchoring cylinder 8 extends to push the slip to clamp the drill pipe, generating frictional force. Under the action of the self-weight of the drill pipe, it will further force the slip to move downward, and the clamping link will generate a greater extrusion force on the slip. Its clamping force increases with the increase of the drill pipe gravity, having the characteristics of self-adaptation and generating a self-locking effect, which is beneficial to protecting the drill pipe.

[0081] On the basis of the above solution, it further includes: a front slewing center 12 provided on the chassis assembly 7 through an ear seat for enabling the mast 1 to rotate around it. The front slewing center 12 enables the entire mast 1 and the parts on the mast 1 to rotate around it, and jointly acts with the ground guiding mechanism 11-1 to control the rising height of the mast 1.

[0082] On the basis of the above solution, it further includes: a ground guiding mechanism 11-1 provided between the mast 1 and the winch 4 and cooperating with the front slewing center 12 for controlling the rising height of the mast 1. The ground guiding mechanism 11-1 is pin-connected to the chassis assembly 7.

[0083] The working principle of the rig for ground drilling is as follows:

[0084] Select the front slewing center 12, the ground angle adjustment cylinder 9-1, the hydraulic wooden horse gripper 10-1, and the ground guiding mechanism 11-1. The mast 1 is hinged and disconnected from the rear slewing center 13. Install the upper section of the mast 1-2 and the forehead 1-1 (the two are always bolted and disassembled synchronously), and install the winch 4. The ground angle adjustment cylinder 9-1 is connected to the pin hole at the upper end of the gripper fixing seat 6. The ground angle adjustment cylinder 9-1 works to control the rising height of the mast 1; when adding drill pipes during drilling, the hydraulic wooden horse gripper 10-1 clamps the first drill pipe, the power head 5-3 releases the first drill pipe and retracts. After the drill pipe to be added is tightened with the first drill pipe in the hole, the power head 5-3 advances to clamp the drill pipe to be added.

[0085] As Figure 7 shown, as a specific implementation manner of the gripper fixing seat 6 in the ground working condition, the hydraulic wooden horse gripper 10-1 is bolted to the gripper mounting plate 6-1, and the two ground angle adjustment cylinders 9-1 are respectively connected to the left and right ground drilling connecting plates 6-3.

[0086] Other structures in this embodiment directly use the corresponding structures in Embodiment 1 and will not be elaborated here.

[0087] Embodiment 3

[0088] Based on the device in Embodiment 2, the present application provides a specific implementation manner of a ground drilling method.

[0089] Step 1: Borehole design;

[0090] Step 2: Implement three connections and one leveling (i.e., power connection, water connection, gas connection, and ground hardening and leveling) at the drill yard, determine the required site size for the drill rig, and provide conditions and space for the kilometer directional drill rig for ground drilling to penetrate.

[0091] Step 3: Adjust the angle between the drill rig and the ground during construction. Use the above-ground angle adjustment cylinder 9-1, hydraulic wooden horse gripper 10-1, and ground guiding mechanism 11-1. Hinge the mast 1 to the rear slewing center 13, install the upper section of the mast 1-2 and the forehead 1-1, and install the winch 4.

[0092] Step 4: Drilling. When adding drill pipes, the hydraulic wooden horse gripper 10-1 clamps the first drill pipe, the power head 5-3 releases the first drill pipe and retreats. After the drill pipe to be added is tightened with the first drill pipe in the borehole, the power head 5-3 advances to clamp the drill pipe to be added.

[0093] Step 5: After the borehole is completed, remove the drill pipe and the drill bit and seal the borehole.

[0094] Embodiment 4

[0095] Based on the device in Embodiment 1, the present application provides a specific implementation manner of a kilometer directional drill rig for downhole drilling.

[0096] As Figure 2 shown, specifically, during downhole drilling, select the downhole angle adjustment cylinder 9-2 provided on the gripper fixed seat 6 and the chuck 10-2 provided at the top of the gripper fixed seat 6 for gripping the drill string during downhole drilling.

[0097] On the basis of the above solution, it further includes: a rear slewing center 13 provided on the chassis assembly 7 for enabling the mast 1 to rotate around it. Specifically, the rear slewing center 13 can be hinged to the top of the mast 1 to enable the mast 1 to rotate around it.

[0098] On the basis of the above solution, it further includes: a downhole guiding mechanism 11-2 provided on the chassis assembly 7 and cooperating with the rear slewing center 13 and the downhole angle adjustment cylinder 9-2 for adjusting the elevation angle of the mast 1. The downhole guiding mechanism 11-2 is pin-connected to the chassis assembly 7.

[0099] The rear slewing center 13 can be hinged to the top of the mast 1 to enable the mast 1 to rotate around it. Together with the combined action of the downhole guiding mechanism 11-2 and the downhole angle adjustment cylinder 9-2, the elevation angle of the mast 1 can be adjusted.

[0100] As a specific embodiment, it further includes a guide wheel 16, an operating platform 17, a power system 14, and a winch 4 provided on the chassis assembly 7.

[0101] The downhole drilling scheme of the drill rig is as follows:

[0102] Select the rear swing center 13, the downhole angle adjustment cylinder 9-2, the hydraulic chuck 10-2, and the downhole guiding mechanism 11-2. Remove the upper section of the mast 1-2, the forehead 1-1, the traveling block 3, the ground guiding mechanism 11-1, and the winch 4. Disconnect the front swing center 12 from the mast 1 by hinge, and install the downhole guiding mechanism 11-2 between the two. The downhole angle adjustment cylinder 9-2 works to control the mast 1 to rotate around the rear swing center 13 and the front end tilts up. When adding drill pipes, the hydraulic chuck 10-2 clamps the drill pipe in the hole of the first drill pipe, the power head 5-3 loosens the first drill pipe and retreats, the power head 5-3 clamps the drill pipe to be added, aligns the thread of the drill pipe to be added with the thread of the first drill pipe in the hole, and the power head 5-3 rotates forward to tighten the drill pipe to be added with the first drill pipe; when it is necessary to disassemble the drill pipe, the power head 5-3 retreats, the hydraulic chuck 10-2 clamps the second drill pipe, the power head 5-3 rotates in reverse to disassemble the thread of the first drill pipe and the second drill pipe, the power head 5-3 loosens the first drill pipe, the first drill pipe is removed, the power head 5-3 advances, clamps the second drill pipe, and the hydraulic chuck 10-2 loosens.

[0103] As Figure 8 As shown, as a specific embodiment of the gripper fixing seat 6 in the downhole working condition, through holes are provided on all four sides of the gripper mounting plate 6-1, the chuck 10-2 is bolted to the gripper mounting plate 6-1, and the downhole angle adjustment cylinder 9-2 is pin-connected to the downhole drilling connecting plate 6-4.

[0104] Other structures in this embodiment directly use the corresponding structures in Embodiment 1 and will not be elaborated here.

[0105] In summary, the integrated underground and above-ground drill rig of the present invention sets two working schemes. By replacing individual detachable parts, the drill rig can achieve multi-angle hole opening (-90° to +20°) underground and above ground. The downhole drilling swing center is placed in the front, and a universal gripper mounting seat for underground and above ground is designed. Connect the downhole drilling lifting cylinder and the gripper, and adopt the original drilling scheme to realize downhole drilling; the ground drilling swing center is placed in the rear, connect the ground lifting cylinder and the wooden horse gripper through the underground and above-ground dual-purpose gripper mounting seat, and be equipped with a detachable mast, a hoisting winch, a core-taking winch, etc. Redesign the transmission route of the power head, optimize the original two motors into one motor, control the side shift of the power head to make the hole opening by a hydraulic cylinder, redesign the feed cylinder, and increase the pulling force to 620 kN on the basis of basically ensuring the original propulsion force, greatly improving the drilling efficiency. In addition, the switching between the two working states of directional drilling and core exploration can be completed by replacing individual parts of the power head.
