Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and in particular to a multi-functional fully hydraulic drilling rig. Background Technology

[0002] A drilling rig is a mechanical device used in geological exploration to drive a drill bit into the ground to obtain physical geological data. Its main function is to drive the drill bit to break the rock at the bottom of the hole and lower or lower the drill bit into the hole. It can be used to drill for core samples, mineral cores, rock cuttings, gaseous samples, and liquid samples to explore underground geology and mineral resources. Hydraulic multi-functional drilling rigs are driven by hydraulic power, offering multiple uses and rapid switching between various drilling techniques. They feature a wide speed range for the power head, high torque, and the energy-saving and highly reliable hydraulic system. Currently, for example, tracked drilling rigs are moved to the drilling site by a tracked vehicle. Then, hydraulically driven support legs support the rig, leveling it to be perpendicular to the ground. The power head connects to the drill rod, and a hydraulic motor drives the power head to rotate, driving the drill rod into the ground to achieve the purpose of core drilling. The sliding guide rails of common fully hydraulic drilling rigs are generally rectangular and welded to the guide rail beam. During the production process, the guide rails are pre-welded to the guide rail beam with a certain allowance, and then processed together with the guide rail beam to ensure the accuracy of the guide rails and eliminate welding deformation. After the guide rails are welded to the main beam, large equipment is required for processing, which increases the difficulty and cost of processing. At the same time, since the guide rails and guide rail beams are already welded together, they cannot be hardened separately, and the surface hardness is generally not high, resulting in a short lifespan. Once worn, they need to be scrapped along with the guide rail beam, making the use and maintenance costs too high. Summary of the Invention

[0003] The purpose of this invention is to provide a guide rail structure for a hydraulic drilling rig and a multi-functional fully hydraulic drilling rig. The sliding seat and the guide rail are connected by a V-shaped groove and a V-shaped slider to prevent the sliding seat from deviating during movement and to ensure precise linear motion.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a guide rail structure for a hydraulic drilling rig, including a guide rail beam and a guide rail set on the guide rail beam, a sliding seat movably provided on the guide rail, a V-shaped cross-section groove provided on the side of the guide rail, a V-shaped cross-section slider provided on the inner side of the sliding seat, the V-shaped cross-section slider being adapted to the V-shaped cross-section groove so that the sliding seat can slide on the guide rail.

[0005] This invention employs the aforementioned technical solution, featuring a V-shaped cross-section groove on the side of the guide rail and a V-shaped cross-section slider on the inner side of the sliding seat. The V-shaped cross-section slider engages with the V-shaped cross-section groove, with the tip of the slider facing the bottom of the groove. When the sliding seat slides along the guide rail, the inclined surface of the V-shaped cross-section slider abuts against the groove surface, and the tip of the slider abuts against the bottom of the groove. Through the coordinated sliding of the V-shaped cross-section groove and the triangular inclined surface of the V-shaped cross-section slider, the sliding seat moves smoothly on the guide rail. When applied to drilling rigs, a power head is installed on the sliding seat. During the reciprocating motion of the sliding seat on the guide rail, the movement is smooth and reliable, without deviation, and the linear motion is precise.

[0006] The guide rail structure of the aforementioned hydraulic drilling rig features wear-resistant plates between the V-shaped cross-section slider and the V-shaped cross-section groove. These wear-resistant plates reduce wear between the slider and the groove.

[0007] The guide rail structure of the aforementioned hydraulic drilling rig has the guide rails fixed to both sides of the guide rail beam by bolts.

[0008] The present invention also provides another technical solution: a multi-functional fully hydraulic drilling rig, including a machine body, a support cylinder, a tilting table and a guide rail structure as described in any of the above technical solutions, the guide rail beam of the guide rail structure is slidably mounted on the tilting table, the two ends of the support cylinder are supported between the machine body and the tilting table, and a power device for driving drilling is provided on the sliding seat.

[0009] The multi-functional fully hydraulic drilling rig of the present invention has a rotatable connection between the support cylinder and the tilting table and the machine body. When the support cylinder is activated, its piston rod pushes the tilting table to rotate around the base, causing the tilting table to stand upright. The guide rail beam can slide along the tilting table. When the tilting table is upright, the bottom end of the guide rail beam supports the ground, playing a role in assisting the support of the drilling rig and preventing the pressure of the leveling legs on the leveling legs due to the rig's own weight. The leveling legs will not be compressed and lose balance to the machine body. During drilling, the power unit connects to the drill rod and drives the drill rod to drill into the ground. The sliding seat can slide back and forth on the guide rail on the support platform, thereby driving the power unit to continuously press the drill rod into the borehole. The sliding seat and the guide rail are connected by a V-shaped cross-section slider and a V-shaped cross-section groove, which enables the sliding seat to drive the power unit to move smoothly in a linear motion.

[0010] The aforementioned multi-functional fully hydraulic drilling rig is equipped with a lifting cylinder on its tilting platform. The two ends of this lifting cylinder are connected to the tilting platform and the guide rail beam, respectively, and are used to drive the guide rail beam to slide on the tilting platform. When the tilting platform is erected, the lifting cylinder drives the guide rail beam to slide on the tilting platform and move towards the ground, thereby causing the guide rail beam to stand upright and support the ground, providing auxiliary support and reducing the pressure on the leveling outriggers.

[0011] The aforementioned multi-functional fully hydraulic drilling rig has pads and clamps on both sides of the tilting table. The clamps are fixed to the tilting table with screws, forming a channel between the clamps and the surface of the tilting table. The bottom edge of the guide beam slides within this channel. The clamps and pads are detachably mounted on the tilting table with screws for easy installation and maintenance. The guide beam slides within the channel between the clamps and the surface of the tilting table, which is created by the gap between the pads and the tilting table. A portion of the clamp is confined to the bottom edge of the guide beam, and the bottom edge of the guide beam is confined within the clamps on both sides of the tilting table. The clamps and pads on both sides of the tilting table guide the guide beam, ensuring that its linear lifting movement does not deviate.

[0012] The aforementioned multi-functional fully hydraulic drilling rig includes a power head mounted on a sliding seat and a hydraulic motor connected to the power head. The hydraulic motor drives the power head to rotate and drill, and the power head, connected to the drill rod and mounted on the sliding seat, moves up and down with the sliding seat to perform drilling operations on the ground.

[0013] The aforementioned multi-functional fully hydraulic drilling rig has a drilling cylinder mounted on the guide beam. The cylinder barrel of the drilling cylinder is fixedly connected to the sliding seat, and the piston rod end of the drilling cylinder is connected to the end of the guide beam. The drilling cylinder, located on the guide beam, drives the sliding seat to move on the guide beam, thereby moving the power head along the drilling direction to achieve drilling of the drill rod.

[0014] The aforementioned multi-functional fully hydraulic drilling rig is equipped with tracks at the bottom of its body. The machine moves on the ground via these tracks, allowing it to adapt to terrains of varying complexity.

[0015] The aforementioned multi-functional fully hydraulic drilling rig has a base on its body. One end of the support cylinder is movably connected to the base, and the other end is movably connected to the tilting table. The base is located on the machine body and is used to install and fix the support cylinder, providing a support point for the support cylinder.

[0016] The beneficial effects achieved by this invention are as follows: The V-shaped groove and V-shaped slider between the guide rail and sliding seat driving the drilling motion of the power unit make the linear motion of the power unit driven by the sliding seat more precise, reliable, and stable. During drilling, the auxiliary support of the guide rail beam reduces the pressure of the drilling rig's own weight on the leveling legs, maintaining the stability of the machine body over long-term use and ensuring that the drilled hole meets the predetermined standards. The use of hydraulic cylinder drive offers advantages such as energy saving, high power, compact structure, and reduced overall weight of the drilling rig. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 5 As shown, a guide rail structure for a hydraulic drilling rig includes a guide rail beam 14 and a guide rail 15 mounted on the guide rail beam 14. A sliding seat 16 is movably mounted on the guide rail 15. A V-shaped groove 151 is provided on the side of the guide rail 15. A V-shaped slider 161 is provided on the inner side of the sliding seat 16. The V-shaped slider 161 is adapted to the V-shaped groove 151, allowing the sliding seat 16 to slide on the guide rail 15. A wear-resistant plate 162 is provided between the V-shaped slider 161 and the V-shaped groove 151. The bottom end of the guide rail beam 14 is provided with serrations 141. The guide rail 15 is fixed to both sides of the guide rail beam 14 by bolts.

[0032] Guide rails 15 are located on both sides of guide rail beam 14, and V-section sliders 161 are located on the side of sliding seat 16. The V-section sliders 161 are embedded in and slide within V-section grooves 151. When sliding seat 16 slides on guide rails 15, the interaction of its triangular inclined surfaces ensures more precise and stable linear movement of sliding seat 16, preventing deviation during movement. The power unit of the drilling rig is mounted on sliding seat 16, driving the drilling action of the power unit.

[0033] like Figures 6-12 As shown, the present invention also discloses a multi-functional fully hydraulic drilling rig, including a body 1 and leveling legs 10 mounted on the body 1. The body 1 is provided with a base 11, a detachably mounted support cylinder 12, and a tilting table 13. One end of the support cylinder 12 is movably connected to the base 11, and the other end is movably connected to the tilting table 13. The tilting table 13 is rotatably mounted on the base 11. A guide beam 14 is slidably mounted on the tilting table 13, and a power device 3 for driving the drill rod to drill holes is slidably mounted on the guide beam 14.

[0034] The machine body 1 moves on the ground via the track 25. When drilling begins, the support cylinder 12 drives the tilting platform 13 to rise. One end of the tilting platform 13 rotates onto the base 11, and the tilting platform 13 drives the guide beam 14 to rise. Once the guide beam 14 is upright on the ground, a lifting cylinder 17 is installed on the tilting platform 13. The piston rod of the lifting cylinder 17 is connected to the guide beam 14, driving the guide beam 14 to slide on the tilting platform 13. The bottom of the guide beam 14 is supported on the ground, thus supporting the machine body 1. The power unit 3 drives the drill rod to drill a hole in the ground. The power unit 3 can slide on the guide beam 14.

[0035] In this embodiment, a guide rail 15 is provided on the guide beam 14, and a sliding seat 16 is slidably mounted on the guide rail 15. The power unit 3 is mounted on the sliding seat 16. The sliding seat 16 can be driven to slide on the guide rail 15 by means of an electric cylinder, a lead screw and nut pair, or hydraulic drive, with hydraulic drive being preferred.

[0036] The tilting table 13 has a pad 18 and a clamping plate 19 on both sides. The clamping plate 19 is fixed to the tilting table 13 by screws. The clamping plate 19 and the surface of the tilting table 13 form a channel. The bottom edge of the guide rail beam 14 is slidably disposed in the channel formed by the clamping plate 19 and the surface of the tilting table 13.

[0037] The power unit 3 includes a power head 31 mounted on a sliding seat 16 and a hydraulic motor 32 connected to the power head 31. The power head 31, mounted on the sliding seat 16, moves linearly along with the sliding seat 16, controlling the drilling of the drill rod. The hydraulic motor 32 drives the power head 31 to rotate via hydraulic pressure, and the rotation of the power head 31 causes the drill rod to rotate and drill a hole.

[0038] A drilling cylinder 20 is mounted on the guide beam 14. The cylinder barrel of the drilling cylinder is fixedly connected to the sliding seat 16, and the piston rod end of the drilling cylinder 20 is connected to the end of the guide beam. When the drilling cylinder 20 extends, it drives the sliding seat 16 to slide on the guide rail 15 of the guide beam 14.

[0039] A clamp 21 is provided at the bottom end of the guide beam 14. A straightener 22 coaxial with the clamp 21 is provided on the clamp 21.

[0040] In this embodiment, a mast 23 and a winch 24 are provided on the top of the guide beam 14. The mast 23 can be folded onto the guide beam 14. The mast 23 can be rotated and folded along the guide beam 14 by means of a pin hinge, making the structure more compact when the guide beam 14 is retracted and moved. The bottom of the machine body 1 is provided with a track 25.

[0041] In a specific implementation of this invention, the equipment is started, and the crawler track 25 moves the drilling rig to the drilling location. The support cylinder 12 actuates, extending its piston rod to lift the tilting platform 13 upwards. Since one end of the tilting platform 13 is movably connected to the base 11, the base 11 tilts upwards, causing the tilting platform 13 and the guide rail beam 14 mounted on it to stand upright. Once the guide rail beam 14 and the power unit 3 mounted on it are vertically perpendicular to the ground, the lifting cylinder 17 actuates, driving the guide rail beam 14 to slide downwards on the tilting platform 13 until its bottom end is supported on the ground. During drilling, the drilling cylinder 20 drives the sliding seat 16 to reciprocate along the guide rail 15 on the guide rail beam 14. Through the cooperation between the guide rail 15 and the slider, the sliding seat 16 moves smoothly along the guide rail 15. The power head 31 is connected to the drill rod, which passes through the clamp 21 and the stabilizer 22. The hydraulic motor 32 drives the power head 31 to rotate, causing the drill rod to drill a hole in the ground. During the drilling process, the drilling cylinder 20 drives the sliding seat 16 to slide on the guide beam 14, thereby increasing the drilling depth.

[0042] In summary, as described in the specification and figures, the present invention has been manufactured into actual samples and subjected to multiple usage tests. The results of these tests demonstrate that the present invention achieves its intended purpose, and its practical value is undeniable. The embodiments described above are merely illustrative examples and are not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention, without departing from the scope of the technical features of the present invention, shall still fall within the scope of the technical features of the present invention.
