Description

TECHNICAL FIELD

[0001] The utility model belongs to mine drilling equipment technical field, more particularly to a device suitable for horizontal seepage hole construction of mine tailing pond. BACKGROUND

[0002] The mine tailing pond refers to the place formed by the dam interception valley or the surrounding land to store the tailings or other industrial waste slag discharged after ore dressing. The horizontal seepage hole is mainly used for draining the seepage water of the tailing dam body, which is connected with the water collecting pipe by arranging the seepage pipe in the dam foundation range or the sedimentation beach at different elevations, so as to guide the seepage water outside the dam.

[0003] In the related art, the staff usually uses the horizontal directional drilling machine to drill at the specified position of the mine tailing pond. The horizontal directional drilling machine is mainly composed of a hydraulic system, a power system, a drill stand, a drill bit and a chassis, the chassis is used for carrying the above structural parts, the hydraulic system is used for providing power for the horizontal movement of the drill stand, and the power system is installed on the drill stand and drives the drill bit to rotate, so as to realize the drilling operation.

[0004] However, in the actual drilling process, the geological conditions of the mine tailing pond, such as the uneven hardness of the stratum, will cause the drill bit to deviate due to uneven stress during drilling. The conventional guide mechanism cannot effectively suppress the radial jumping of the drill rod, so that the straightness deviation of the hole exceeds the engineering allowable deviation range, and further affects the seepage engineering. UTILITY MODEL CONTENTS

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] like Figs. 1-2 As shown, the device for constructing horizontal drainage holes in mine tailings dams provided by this utility model includes a vehicle body 100, a dual-cylinder synchronous lifting mechanism, a load-bearing column 300, a support column 500, a propulsion mechanism 600, a drill rod 800, and a dynamic locking anti-deviation mechanism. The vehicle body 100 consists of a frame and a carriage. The frame is the main part supporting the entire drilling device and is typically made of rigid metal material, possessing sufficient strength and rigidity to withstand various loads on related components. The carriage is mounted on the frame and mainly carries the corresponding drive components. Two sets of four mine car wheels 110 are symmetrically arranged at the bottom of the vehicle body 100. The vehicle body 100 can move within the mine tailings dam via these mine car wheels 110, thereby moving the drilling device to the designated position.

[0030] The dual-cylinder synchronous lifting mechanism includes two vertical hydraulic cylinders 200 symmetrically arranged within the vehicle body 100. Specifically, with the centerline along the length of the vehicle body 100 as the axis of symmetry, the two vertical hydraulic cylinders 200 are symmetrically arranged inside the vehicle body 100. The piston rod of each vertical hydraulic cylinder 200 vertically penetrates the top plate of the vehicle body 100 and extends to the top of the vehicle body 100, thus enabling the lifting operation by moving the piston rod up and down in the upper region of the vehicle body 100. Furthermore, the two symmetrically arranged vertical hydraulic cylinders 200 are synchronously controlled through a flow divider / combiner valve.

[0031] A flow divider / combiner valve is a general term for flow dividers, combiners, one-way flow dividers, one-way combiners, and proportional flow dividers in hydraulic valves. It is mainly used in hydraulic systems with dual-cylinder and multi-cylinder synchronous control. Through internal pressure and flow-sensitive components, it automatically adjusts to ensure synchronized movement of the cylinders. Preferably, each vertical hydraulic cylinder 200 is also equipped with a pressure sensor electrically connected to its bottom to provide real-time feedback of the load pressure, thereby reducing errors in the synchronous movement of the cylinders. The above structure is well-known to those skilled in the art, and will not be described in detail here.

[0032] In this embodiment, the piston rods of each vertical hydraulic cylinder 200 are coaxially fixed with a load-bearing column 300 and a support column 500. The bottom of the load-bearing column 300 is fixedly connected to the end of the piston rod of one of the vertical hydraulic cylinders 200. The load-bearing column 300 is also welded with a load-bearing plate 310 via a circumferential weld, and the center line of the load-bearing plate 310 in the vertical direction coincides with the axis of the load-bearing column 300. Furthermore, two parallel guide columns 400 are vertically fixed to the working surface of the load-bearing plate 310, both extending horizontally and parallel to the top plate of the vehicle body 100.

[0033] like Fig. 1 and Fig. 2 As shown, the bottom of the support column 500 is fixedly connected to the piston rod end of another vertical hydraulic cylinder 200. Similarly, a support plate 510 is welded to the support column 500 via a circumferential weld, the vertical centerline of which coincides with the axis of the support column 500. Two parallel guide columns 400, fixedly installed on the working surface of the load-bearing plate 310, extend towards the support plate 510 and vertically penetrate it to its side area. In other words, the support column 500 and the support plate 510 provide lateral support to the other end of the guide columns 400.

[0034] The propulsion mechanism 600 is a frame structure that drives the drill rod 800 to move horizontally. Its main function is to support and propel the drill rod 800 for drilling operations. Two sets of four sliding sleeves 610 are symmetrically arranged at the bottom of the propulsion mechanism 600. The axes of two sliding sleeves 610 on the same side coincide, allowing the propulsion mechanism 600 to be fitted onto the guide rod via the sliding sleeves 610 at its bottom, achieving a slidable assembly with the guide rod. A transmission rod 700 is rotatably mounted in the middle of the propulsion mechanism 600 via a slewing bearing 970. The end of the transmission rod 700 is coaxially fixed to the piston rod of the transverse hydraulic cylinder 710. The transverse hydraulic cylinder 710 is vertically fixed to the working surface of the support plate 510 via a cylinder base, thereby controlling the horizontal movement of the propulsion mechanism 600 along the guide rod.

[0035] Preferably, each guide post 400 has a hard chrome plating on its surface, and a limiting boss is provided at the end of the guide post 400 near the support. Conversely, the inner wall of the sliding sleeve 610 is inlaid with a graphite self-lubricating bushing. This structure greatly reduces the sliding resistance of the propulsion mechanism 600, thereby ensuring smooth operation of the propulsion mechanism 600.

[0036] The dynamic locking anti-deviation mechanism includes symmetrically arranged stabilizing plates 900. Each stabilizing plate 900 has a semi-circular groove 910 on its surface near the drill rod 800. The two semi-circular grooves 910 are fixedly connected to the outer ring of the bearing 970 using epoxy resin adhesive. Connecting rods 920 are hinged to the middle of both sides of each stabilizing plate 900. The other end of each connecting rod 920 is rotatably connected to a pin hinge 980, which is fixed symmetrically at the upper and lower positions on the working surface of the support plate 510. Furthermore, each stabilizing plate 900 has a positioning through hole 930 along its thickness in the apex region.

[0037] Specifically, the end of the drill rod 800 is coaxially connected to the output shaft of the reducer 810 via a flange. The reducer 810 is also directly connected to the servo drive motor 820, which provides rotational power to the reducer 810 and the drill rod 800. Simultaneously, the drill rod 800 vertically penetrates the support plate 510 and extends to its side area. The drill rod 800 is connected to the inner ring of the bearing 970 via an interference fit. The drill rod 800 and the support plate 510 have a clearance fit. By activating the servo drive motor 820 and the reducer 810, the drill rod 800 can be controlled to perform drilling operations at designated locations.

[0038] In this embodiment, a locking rod 940 is inserted into the positioning through hole 930 of the symmetrically arranged stabilizing clamps 900. The locking rod 940 passes through the stabilizing clamps 900 and extends below them. A transverse through hole 950 is provided on the portion of the locking rod 940 below the stabilizing clamps 900, and an insert plate 960 is provided within this transverse through hole 950. When the insert plate 960 is inserted into the transverse through hole 950 of the locking rod 940, the locking rod 940 can form a constraint mechanism between the two symmetrically arranged stabilizing clamps 900 and dynamically maintain the drill rod 800 in a horizontal state through the semi-circular groove 910.

[0039] During actual drilling operations, the dual-cylinder synchronous lifting mechanism first controls the two vertical hydraulic cylinders 200 to lift synchronously via a flow divider / combiner valve, so that both the load-bearing plate 310 and the support part reach the designated height. The operator can precisely adjust the initial position of the propulsion mechanism 600 through the scale markings on the through guide column 400.

[0040] When the servo motor drives the drill rod 800 to rotate at a specific speed via the reducer 810, the transverse hydraulic cylinder 710 can automatically adjust the pushing pressure based on the pushing resistance value fed back by the pressure sensor, causing the pushing mechanism 600 to move horizontally along the guide rod. When encountering hard interlayers, the stabilizing clamp 900 of the dynamic locking anti-deviation mechanism will maintain rolling contact with the drill rod 800 through the bearing 970, thereby preventing excessive radial movement of the drill rod 800.

[0041] In the device for constructing horizontal drainage holes in mine tailings dams provided by this utility model, a dynamic locking anti-deviation mechanism is provided on the side of the drill rod 800. This mechanism achieves horizontal dynamic constraint through four connecting rods 920 and two symmetrically positioned stabilizing plates 900. When the drill rod 800 deviates radially, the deviation force causes the stabilizing plates 900 to rotate slightly relative to the hinge 980. At this time, the constraint mechanism formed by the four connecting rods generates a reverse constraint force to ensure that the drill rod 800 is dynamically maintained in a horizontal state. This structural design greatly avoids deviations in the drill rod 800 during horizontal drilling operations and ensures that the radial deviation of the drill rod 800 is within a reasonable range.

[0042] In some embodiments, the top of the locking rod 940 is provided with a limiting cap 990 that is larger than the outer diameter of the positioning through hole 930. The locking rod 940 abuts against the surface of the stabilizing clamp 900 through the limiting cap 990. This can effectively prevent the locking rod 940 from disengaging under vibration conditions, so as to ensure that the dynamic constraint anti-deviation mechanism can always be in working condition.

[0043] In some embodiments, both ends of the connecting rod 920 in the axial direction are provided with reinforcing ribs 921 extending along its axial direction, and the cross-section of the reinforcing ribs 921 is triangular. By providing multiple reinforcing ribs 921, the bending strength of the connecting rod 920 can be improved, thereby effectively preventing deformation at the hinge of the connecting rod 920.

[0044] It should be noted that, unless otherwise expressly specified and limited, the term "connection" or its synonyms should be interpreted broadly in this document. For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.

Furthermore, expressions such as "first" and "second" are merely used to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
