Description

[0002] The mine horizontal dewatering hole is drilled into the horizontal or nearly horizontal hole on the open pit slope, and its principle is to reduce the underground water in the rock fissure of the slope to reduce the water pressure, prevent the slope instability caused by the infiltration of underground water, and further improve the stability of the open pit slope.
[0003] In the related art, a drilling machine is generally used to drill the horizontal dewatering hole on the open pit slope, and then a drainage device (such as a drainage pipe or a water pump) is installed in the horizontal dewatering hole to drain the underground water.

Once the deviation angle of the drill bit is too large, the dewatering range of the horizontal dewatering hole will be reduced, so that the underground water in the target area cannot be effectively drained.

DETAILED DESCRIPTION
[0032] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will combine the utility model specific embodiment and corresponding drawings to make the utility model technical scheme clear, complete description. Obviously, the described embodiment is only a part of the utility model embodiment, rather than all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the scope of the utility model protection.
[0033] As Figures 1-5 The device for mine horizontal dewatering hole construction of the utility model includes vehicle body 100, lifting mechanism, guide assembly, drilling mechanism, two support bases 700 and support bridge 800, wherein the vehicle body 100 is the bearing structure of the drilling construction device, the bottom of the vehicle body 100 is symmetrically provided with two groups of mine car wheels 110 for walking in the mine, and the drilling construction device can be moved to the construction position of the horizontal dewatering hole by relying on the mine car wheels 110.
[0034] The lifting mechanism is composed of vertical hydraulic cylinder 210, stand 200 and longitudinal connecting plate 300, wherein the vertical hydraulic cylinder 210 is fixedly arranged in the inner cavity of the vehicle body 100, and the piston rod of the vertical hydraulic cylinder 210 penetrates the top surface of the vehicle body 100. When the piston rod moves downward to the lowest position, the top surface of the piston rod is flush with the top surface of the vehicle body 100. Therefore, the piston rod can move in the area above the top surface of the vehicle body 100, and the moving path is perpendicular to the top surface of the vehicle body 100.
[0035] As Figures 1-3As shown, the column 200 is a circular steel tube structure rigidly connected to the top surface of the vehicle body 100. Its main function is to support and transfer loads, thus providing sufficient stability and load-bearing capacity for the structure. The column 200 is fixedly connected to the piston rod of the vertical hydraulic cylinder 210; specifically, the two can be connected by an interference fit. The longitudinal connecting plate 300 is a steel plate structure of a certain thickness. The longitudinal connecting plate 300 is welded and fixed to the column 200 by a circumferential weld, and the vertical centerline of the working surface of the longitudinal connecting plate 300 coincides with the axis of the column 200. Therefore, the column 200 and the longitudinal connecting plate 300 can move under the action of the vertical hydraulic cylinder 210.
[0036] The guide assembly includes two guide rods 400, the ends of which are horizontally mounted on the working surface of the longitudinal connecting plate 300. With the vertical centerline of the working surface of the longitudinal connecting plate 300 as the axis of symmetry, the two guide rods 400 are symmetrically arranged on the working surface of the longitudinal connecting plate 300.
[0037] The drilling mechanism consists of a transverse hydraulic cylinder 510, a drive frame 500, and a drill bit 600. The cylinder body of the transverse hydraulic cylinder 510 is rigidly connected to the working surface of the longitudinal connecting plate 300, and the transverse hydraulic cylinder 510 is located above the guide rods 400. The piston rod of the transverse hydraulic cylinder 510 is fixedly connected to the drive frame 500. A sleeve is provided at the bottom of the drive frame 500, through which the drive frame 500 is slidably fitted onto the outside of the two guide rods 400. The drive frame 500 is driven to rotate by a reduction mechanism 610. Therefore, the transverse hydraulic cylinder 510 can control the drive frame 500 to move along the axis of the guide rods 400, thereby realizing the horizontal feed function of the drill bit 600.
[0038] like Figures 1-3 As shown, two support bases 700 are symmetrically arranged on the top surface of the vehicle body 100 about the center line of the guide rod 400 axis. Each support base 700 also has two vertical guide posts 710 vertically connected to it at its top. Each vertical guide post 710 has a through locking hole 711 in the horizontal direction. Preferably, the vertical guide rod 400 has several locking holes 711 along its axial direction, and these locking holes 711 are evenly distributed on the vertical guide rod 400.
[0039] In contrast, the bottom of the support bridge 800 is sleeved outside the vertical guide column 710 and can slide in the vertical direction relative to the support base 700. Wherein, when the locking rod 900 is inserted into the locking hole 711, the top of the support bridge 800 is rigidly constrained to the guide rod 400 under the support of the locking rod 900, so that the feed axis of the drill bit 600 is parallel to the horizontal plane. Specifically, the included angle between the feed axis and the horizontal plane is less than or equal to 0.05°. Preferably, the end of the locking rod 900 is provided with a limiting portion 910.
[0040] In the device suitable for horizontal dry hole construction in mines, the support base 700 is arranged below the guide rod 400 for guiding the drilling mechanism, and the support bridge 800 arranged at the top of the support base 700 is rigidly constrained to the guide rod 400 through the locking rod 900. When the drill bit 600 of the drilling mechanism is driven to move along the guide rod 400 by the driving frame 500, the support base 700, the support bridge 800 and the guide rod 400 can constrain the horizontal movement of the drill bit 600 and the driving frame 500, thereby effectively inhibiting the vibration deviation of the drill bit 600 during feeding, and greatly reducing the trajectory deviation angle of the horizontal dry hole, so as to ensure that the dry hole has a normal dry range.
[0041] In some embodiments, each support base 700 is detachably mounted on the top surface of the vehicle body 100, for example, in a bolted manner. Preferably, the top surface of the vehicle body 100 is provided with a waist hole 120 of a certain length, which extends along the length direction of the top surface of the vehicle body 100. The mounting position of each support base 700 can be adjusted along the length direction of the waist hole 120 by bolts, and the adjustment stroke of the support base 700 covers the full length of the waist hole 120. By adjusting the position of the support base 700 on the waist hole 120, the drilling depth requirement can be matched according to different geological conditions. Moreover, the bolted detachable connection can facilitate timely replacement and maintenance of the support base 700, thereby reducing the downtime of the equipment.
[0042] In some embodiments, the top of the support bridge 800 is provided with a semicircular groove 810, the curvature of the semicircular groove 810 matches the bottom of the guide rod 400, and the support bridge 800 is in contact with the bottom of the guide rod 400 through the semicircular groove 810. Preferably, the surface of the semicircular groove 810 can also be provided with a wear-resistant layer of polyester amine material. The use of the semicircular groove 810 can improve the adaptability of the support bridge 800 and the guide rod 400, the wear-resistant layer can reduce the wear degree of the component contact and absorb the energy when the drill bit 600 vibrates, thereby inhibiting resonance and further improving the drilling accuracy of the drill bit 600.
[0043] In some embodiments, the width of the support bridge 800 is greater than the distance between the centers of the two guide rods 400, and a limiting boss is arranged on both sides of the support bridge 800. The limiting boss corresponds to the sliding path of the driving frame 500, and the limiting boss is used to block the driving frame 500 to play a limiting role, so that the support bridge 800 can be prevented from accidentally sliding off the guide rod 400.
[0044] In some embodiments, the guide rod 400 is fixedly connected to the working surface of the longitudinal connecting plate 300 through the flange plate 420, and a triangular reinforcing rib 410 is arranged at the connection between the guide rod 400 and the flange plate 420, and the triangular reinforcing rib 410 extends along the axis direction of the guide rod 400. By adopting the above structure design, the stress distribution of the guide rod 400 can be optimized through the triangular reinforcing rib 410, so that the problem of fracture due to fatigue of the guide rod 400 can be avoided.
[0045] In some embodiments, the axis of the vertical guide column 710 and the axis of the guide rod 400 are perpendicular to each other, and the intersection between the two is located on the feed route of the drill bit 600, so as to ensure that the feed torque of the drill bit 600 is symmetrically distributed, thereby inhibiting the negative influence of the deflection torque.
[0046] It should be noted that, in this document, unless otherwise explicitly specified and limited, the term "connection" or its synonyms should be understood in a broad sense, for example, "connection" can be fixed connection, can also be detachable connection; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, and those skilled in the art can understand the specific meaning of the above-mentioned terms in the utility model according to the specific circumstances. Moreover, expressions such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
