Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and in particular to a scheelite slope mining device and method. Background Technology

[0002] 80% of the world's mined scheelite is used to smelt high-quality steel, 15% is used to produce hard steel, and 5% is used for other purposes; tungsten alloys can be used in the manufacture of firearms and cutting metals, and their applications are very wide.

[0003] Scheelite is mainly produced in contact metasomatic deposits and high- to medium-temperature hydrothermal deposits. The mining method for open-pit scheelite is generally deep-hole blasting, which involves drilling holes in the mining area, filling the holes with explosives, and using the impact force generated by the explosion to break the ore. Existing technologies include machines that can be remotely operated by workers to automatically drill holes in the mining area, such as the Epiroc PitViper automatic blasting drill, which slides on vertical rails.

[0004] When the device is drilling on a slope, it rests on the inclined slope. Because the vertically set slide rail is relatively long, when the slide rail is vertical, the overall center of gravity of the device shifts downward. When the slope is steep, the device may tip over when the center of gravity deviates from the device.

[0005] Therefore, we propose a scheelite slope mining device and its forming method. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a scheelite slope mining device and method, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a scheelite slope mining device, comprising...

[0008] A base; a roller is rotatably connected to the bottom of the base, and a drive motor is fixedly connected to the base to drive the roller;

[0009] A sliding rail; the sliding rail is mounted on the base, a mounting seat is slidably fitted on the sliding rail, and a moving motor is fixedly connected to the upper end of the sliding rail; a lead screw that is threadedly fitted to the mounting seat is fixedly connected to the output end of the moving motor; a drilling rig is fixedly connected to the mounting seat; a drill bit is fixedly connected to the output shaft of the drilling rig.

[0010] Remote control device;

[0011] A support mechanism is provided at one end of the base away from the sliding rail, and the support mechanism is able to support the center of gravity of the base to one side when the drilling rig and the drill bit are drilling on the slope.

[0012] Preferably, the support mechanism includes a support hydraulic rod and a support plate; the support plate is connected to the lower end of the base, the support hydraulic rod is rotatably connected to both sides of the base, and the output end of the support push rod is connected to the support plate.

[0013] Preferably, at least three of the support plates are hinged together end to end; the output end of the support hydraulic rod is rotatably connected to the support plate;

[0014] The upper surface of the support plate is provided with a connecting structure; the connecting structure includes a connecting electric push rod, a connecting block and two connecting cylinders; the connecting electric push rod is fixedly connected to one side of the support plate; the connecting block is fixedly connected to the output end of the connecting electric push rod; the two connecting cylinders are respectively fixedly connected to the corresponding support plate and the adjacent support plate; the connecting block can be inserted into the two connecting cylinders.

[0015] By setting a support plate on the side of the base away from the sliding rail installation position, when drilling on the slope, the support hydraulic rod pushes the support plate, causing the support plate to contact the slope, thus offsetting the overall center of gravity shift of the invention on the slope and preventing the invention from tipping over due to the center of gravity shifting away from the base. At the same time, multiple support plates are hinged together. When the base needs to be supported, the multiple support plates are flattened to form a flat plate, which is supported on the ground. This ensures the contact area between the support plate and the ground while minimizing the volume of the support plate on the base, preventing the support plate from affecting the subsequent rotation of the sliding rail and its support on the base.

[0016] Preferably, two adjacent support plates are hinged together by a torsion spring hinge; the torque of the torsion spring hinge causes the support plates to tend to move closer to each other.

[0017] Preferably, a sliding groove is formed on the end face of the base away from the sliding rail; a sliding block is slidably connected in the sliding groove; a sliding motor is fixedly connected in the sliding groove; a sliding rod that is threadedly engaged with the sliding block is fixedly connected to the output shaft of the sliding motor; and the support plate is rotatably connected to the sliding block.

[0018] By setting up a sliding motor and sliding block, the support plate is lifted off the ground after being folded up, maintaining a certain distance from the ground, and then contacts the ground when unfolded. This prevents the support plate from bumping into protruding soil or ore on the ground when the invention is moved, thus preventing damage to the support plate and affecting the movement of the invention.

[0019] Preferably, a rotating block is rotatably connected to the base; the rotating block is rotatably connected to the sliding rail; a rotating hydraulic rod and a deflecting hydraulic rod are fixedly connected to the base; the output end of the steering hydraulic rod is rotatably connected to the sliding rail; the two deflecting hydraulic rods are located on both sides of the rotating block and their output ends are rotatably connected to the rotating block.

[0020] In this embodiment, in the initial state, the output end of the rotating hydraulic push rod retracts, making the sliding rail horizontal, with the end away from the rotating block supported by the base. When drilling is required, the operator uses a remote control to extend the output end of the rotating hydraulic push rod, pushing the sliding rail upward to make it vertical. The operator can also use the remote control to further extend or shorten the output end of the rotating hydraulic push rod, causing the sliding rail to be tilted laterally. Therefore, when the mounting block, carrying the drilling rig and drill bit, moves downward along the sliding rail, the hole drilled on the slope is an inclined hole, improving the drilling efficiency of this invention. Style range; Compared to vertical holes, inclined holes have an equal blasting resistance line along the entire length of the borehole, resulting in more uniform ore crushing during blasting, less likely to produce large pieces or leave any residue. Furthermore, the inclined hole can maintain the required step slope angle by adjusting the drilling angle, resulting in a smoother slope after blasting. The operator can also control the output ends of the two deflecting hydraulic rods to extend and retract respectively, thereby causing the rotating block to deflect the sliding rail. The sliding rail is inclined in the longitudinal direction, which, in conjunction with the rotating hydraulic push rod causing the sliding rail to be inclined in the transverse direction, allows the drilling rig and drill bit to drill inclined holes at any angle within a certain angle range.

[0021] By rotatably connecting the sliding rail to the rotating block, and then rotatably connecting the rotating block to the base, the invention can control the rotating hydraulic rod or the biasing hydraulic rod to push the sliding rail or the rotating block when it is necessary to drill an inclined hole, or push the sliding rail and the rotating block at the same time, thereby enabling the invention to drill an inclined hole and improving the functionality and scope of application of the invention.

[0022] Preferably, the rotating block is inclined on the side away from the support plate.

[0023] A method for slope mining of scheelite, applicable to the aforementioned scheelite slope mining apparatus, comprises the following steps:

[0024] S1. The staff controls the drive motor to roll the rollers through the remote control device, so that the scheelite slope mining device of the present invention can reach the mining area. Then, the staff controls the sliding rail to be vertical, and the drill and drill bit drill along the sliding rail.

[0025] S2. When the scheelite slope mining equipment is stopped on the slope of the mining area, the workers control the support hydraulic rod to push the support plate to support the end away from the installation position of the sliding rail.

[0026] S2. The staff controls the sliding rail to stand up using a remote control device, and then controls the drilling machine and drill bit to drill holes; when it is necessary to drill an inclined hole, the sliding rail is tilted, or the rotating block is set to tilt the sliding rail, so that the drilling machine and drill bit drill an inclined hole on the slope along the inclined sliding rail.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention provides a support plate on the side of the base away from the sliding rail installation position. When drilling on a slope, the hydraulic rod pushes the support plate, causing it to contact the slope. This counteracts the shift of the overall center of gravity of the invention on the slope, preventing the invention from tipping over due to the center of gravity deviating from the base. Simultaneously, multiple support plates are hinged together. When the base needs support, the multiple support plates are flattened to form a flat plate, which is then supported on the ground. This ensures sufficient contact area between the support plates and the ground while minimizing the volume of the support plates on the base, preventing them from affecting the subsequent rotation of the sliding rail and its support on the base.

[0029] 2. By setting up a sliding motor and a sliding block, the support plate is lifted off the ground after being folded and kept at a certain distance from the ground, and then contacts the ground when unfolded. This prevents the support plate from bumping into protruding soil or ore on the ground when the invention is moved, thus preventing damage to the support plate and affecting the movement of the invention.

[0030] 3. By rotatably connecting the sliding rail to the rotating block, and then rotatably connecting the rotating block to the base, the present invention can control the rotating hydraulic rod or the biasing hydraulic rod to push the sliding rail or the rotating block when it is necessary to drill an inclined hole, or push the sliding rail and the rotating block at the same time, so that the present invention can drill an inclined hole, thereby improving the function and scope of application of the present invention.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Refer to the instruction manual appendix Figure 1 A scheelite slope mining apparatus, comprising

[0042] Base 1; a roller 2 is rotatably connected to the bottom of base 1, and a drive motor is fixedly connected to base 1 to drive the roller 2.

[0043] Sliding rail 3; Sliding rail 3 is mounted on base 1, mounting seat 31 is slidably fitted on sliding rail 3, and moving motor 32 is fixedly connected to the upper end of sliding rail 3; a lead screw 33 that is threadedly fitted to mounting seat 31 is fixedly connected to the output end of moving motor 32; a drilling machine 34 is fixedly connected to mounting seat 31; a drill bit 35 is fixedly connected to the output shaft of drilling machine 34.

[0044] Remote control device;

[0045] Support mechanism 4; Support mechanism 4 is located at the end of the base 1 away from the sliding rail 3. Support mechanism 4 can support the center of gravity of the base 1 to one side when the drilling machine 34 and the drill bit 35 are drilling on the slope.

[0046] Refer to the instruction manual appendix Figure 1In this embodiment, the support mechanism 4 includes a support hydraulic rod 41 and a support plate 42; the support plate 42 is connected to the lower end of the base 1, the support hydraulic rod 41 is rotatably connected to both sides of the base 1, and the output end of the support push rod is connected to the support plate 42.

[0047] Refer to the instruction manual appendix Figure 2 In this embodiment, at least three support plates 42 are hinged together end to end; the output end of the support hydraulic rod 41 is rotatably connected to the support plate 42.

[0048] The support plate 42 has a connecting structure 43 on its upper surface after unfolding. The connecting structure 43 includes a connecting electric push rod 44, a connecting block 45, and two connecting cylinders 46. The connecting electric push rod 44 is fixedly connected to one side of the support plate 42. The connecting block 45 is fixedly connected to the output end of the connecting electric push rod 44. The two connecting cylinders 46 are respectively fixedly connected to the corresponding support plate 42 and the adjacent support plate 42. The connecting block 45 can be inserted into the two connecting cylinders 46.

[0049] In this embodiment, the invention is remotely controlled by staff. The staff controls the controller through a remote control device, and the controller then controls the various electrical components in the invention. In this embodiment, the base 1 is equipped with components such as a hydraulic oil pump and a hydraulic cylinder to provide power to the hydraulic rod in the invention.

[0050] The operator remotely controls the controller via a remote control device, which in turn controls the drive motor to rotate the roller 2, thus moving the invention. When the invention moves to a slope in the mining area and drilling is required, the operator remotely controls the drive motor to stop moving and extends the output end of the support hydraulic rod 41, causing the support hydraulic rod 41 to push the support plate 42, causing the support plate 42 to deflect downwards until it contacts and adheres to the slope. At this point, the operator remotely controls the moving motor 32 via the remote control device to rotate the lead screw 33, thereby causing the lead screw 33 to rotate through the contact with the slope. The threaded engagement between the mounting bases 31 allows the mounting bases 31 to move downwards along the sliding rail 3 with the drilling rig 34 and the drill bit 35. At the same time, the operator controls the drilling rig 34 to rotate with the drill bit 35 via a remote control device, thereby drilling holes on the slope for placing explosives. When the sliding rail 3 is erected, the support plate 42 is supported by the support hydraulic rod 41. The supporting force of the ground on the support plate 42 is transmitted to the side of the base 1 away from the sliding rail 3 through the support hydraulic rod 41, which counteracts the shift of the overall center of gravity of the invention on the slope and prevents the overall center of gravity of the invention from shifting away from the base 1 and causing it to tip over.

[0051] In this embodiment, multiple support plates 42 are hinged together. In the initial state, the support plates 42 are folded. When the support hydraulic rod 41 pushes the support plate 42 that is furthest away, the furthest support plate 42 pulls the adjacent support plate 42, causing all the support plates 42 to be pulled and unfolded. Under the pull of the support hydraulic rod 41 with the furthest support plate 42, the folded support plate 42 is flattened. Then, the operator controls the output end of all the connecting electric push rods 44 to extend through the remote control device, pushing the corresponding connecting block 45, so that the connecting block 45 is inserted into the corresponding connecting cylinder 46 on the support plate 42 and the connecting cylinder 46 on the adjacent support plate 42. Thus, the connecting block 45 fixes the two support plates 42 relative to each other. At this time, all the support plates 42 are equivalent to a flat plate, supported on the slope.

[0052] This invention provides a support plate 42 on the side of the base 1 away from the installation position of the sliding rail 3. When drilling on a slope, the hydraulic rod 41 pushes the support plate 42, causing it to contact the slope. This counteracts the shift of the overall center of gravity of the invention on the slope, preventing the invention from tipping over due to the center of gravity deviating from the base 1. Simultaneously, multiple support plates 42 are hinged together. When the base 1 needs support, the multiple support plates 42 are flattened to form a flat plate, which is then supported on the ground. This ensures the contact area between the support plate 42 and the ground while minimizing the volume of the support plate 42 on the base 1, preventing the support plate 42 from affecting the subsequent rotation of the sliding rail 3 and its support on the base 1.

[0053] Refer to the instruction manual appendix Figure 4 In this embodiment, two adjacent support plates 42 are hinged together by a torsion spring hinge 47; the torsion of the torsion spring hinge 47 causes the support plates 42 to tend to move closer to each other.

[0054] When it is necessary to retract the support plate 42, the operator controls the output ends of all the connecting electric push rods 44 to retract via a remote control device, thereby pulling the connecting block 45 out of the two connecting cylinders 46 and releasing the fixation between the two adjacent support plates 42. Then, the operator controls the output ends of the support hydraulic rods 41 to retract via a remote control device, thereby pulling the farthest support plate 42. Under the action of the torsion spring hinge 47, the two adjacent support plates 42 tend to move closer to each other and fold together. As the output ends of the support hydraulic rods 41 gradually retract, the support plates 42 rotate relative to each other and fold together, thereby completing the folding of the support plate 42.

[0055] Refer to the instruction manual appendix Figure 4In this embodiment, a sliding groove 5 is provided on the end face of the base 1 away from the sliding rail 3; a sliding block 51 is slidably connected in the sliding groove 5; a sliding motor 52 is fixedly connected in the sliding groove 5; a sliding rod 53 that is threadedly engaged with the sliding block 51 is fixedly connected to the output shaft of the sliding motor 52; and a support plate 42 is rotatably connected to the sliding block 51.

[0056] In this embodiment, the support plate 42 is rotatably connected to the sliding block 51. In the initial state, the bottom of the folded support plate 42 is a certain distance from the ground. Before the support plate 42 needs to be unfolded, the operator controls the sliding motor 52 to rotate the sliding rod 53 through a remote control device. Through the threaded engagement between the sliding rod 53 and the sliding block 51, the sliding rod 53 causes the sliding block 51 to move downward when it rotates, thereby causing the sliding block 51 to move the support plate 42 downward. At this time, the lower end of the support plate 42 contacts the ground, and the sliding motor 52 stops rotating. When folding the support plate 42, the operator controls the sliding motor 52 to rotate in the opposite direction through a remote control device, causing the sliding block 51 to move the support plate 42 upward, thereby creating a certain distance between the support plate 42 and the ground.

[0057] The present invention uses a sliding motor 52 and a sliding block 51 to make the support plate 42 detach from the ground after being folded up, maintain a certain distance from the ground, and then contact the ground when unfolded. This prevents the support plate 42 from bumping into protruding soil or ore on the ground when the invention is moved, thus preventing damage to the support plate 42 and affecting the movement of the invention.

[0058] Example 2:

[0059] Refer to the instruction manual appendix Figure 1 and 6 Based on Embodiment 1, in this embodiment, a rotating block 6 is rotatably connected to the base 1; the rotating block 6 is rotatably connected to the sliding rail 3; a rotating hydraulic rod 61 and a deflecting hydraulic rod 62 are fixedly connected to the base 1; the output end of the steering hydraulic rod is rotatably connected to the sliding rail 3; the two deflecting hydraulic rods 62 are located on both sides of the rotating block 6 and their output ends are rotatably connected to the rotating block 6.

[0060] In this embodiment, in the initial state, the output end of the rotating hydraulic push rod retracts, making the sliding rail 3 horizontal, with the end away from the rotating block 6 supported by the base 1. When drilling is required, the operator controls the output end of the rotating hydraulic push rod to extend via a remote control, pushing the sliding rail 3 upward to make it vertical. The operator can also control the output end of the rotating hydraulic push rod to extend or shorten further via the remote control, thereby tilting the sliding rail 3 laterally. This ensures that when the mounting block, carrying the drilling rig 34 and drill bit 35, moves downward along the sliding rail 3, the hole drilled on the slope is an inclined hole, improving the drilling efficiency of this invention. Style range; Compared to vertical holes, inclined holes have an equal blasting resistance line along the entire length of the blast hole, resulting in more uniform crushing of the ore during blasting, making it less likely to produce large pieces or leave any residue. Furthermore, the inclined hole can maintain the required step slope angle by adjusting the drilling angle, resulting in a relatively flat slope after blasting. The operator can also control the output ends of the two deflecting hydraulic rods 62 to extend and retract respectively, thereby causing the rotating block 6 to deflect the sliding rail 3. The sliding rail 3 is inclined in the longitudinal direction, which cooperates with the rotating hydraulic push rod to make the sliding rail 3 inclined in the transverse direction, thus enabling the drilling rig 34 and the drill bit 35 to drill inclined holes at any angle within a certain angle range.

[0061] This invention rotatably connects the sliding rail 3 to the rotating block 6, and then rotatably connects the rotating block 6 to the base 1. This allows the invention to control the rotating hydraulic rod 61 or the biasing hydraulic rod 62 to push the sliding rail 3 or the rotating block 6 when it is necessary to drill an inclined hole. Alternatively, it can push the rotating block 6 while pushing the sliding rail 3, thereby enabling the invention to drill an inclined hole and improving the functionality and scope of application of the invention.

[0062] Refer to the instruction manual appendix Figure 3 In this embodiment, the rotating block 6 is tilted on the side away from the support plate 42.

[0063] Refer to the instruction manual appendix Figure 7 In this embodiment, the side of the rotating block 6 away from the support plate 42 is tilted so that when the sliding rail 3 tilts the drill 34 and the drill bit 35, the tilted side of the rotating block 6 can avoid the drill bit 35, so that the drill bit 35 will not touch the rotating block 6 when it tilts within a certain range, thus preventing the rotating block 6 from affecting the tilt range of the drill bit 35.

[0064] Example 3:

[0065] Refer to the instruction manual appendix Figure 7Based on Embodiment 1 and Embodiment 2, in this embodiment, two first electric push rods 7 can be spherically hinged on both sides of the sliding rail 3. Rollers 2 are rotatably connected to the output end of the first electric push rod 7. Then, second electric push rods 71 ​​are spherically hinged on both sides of the sliding rail 3. The second electric push rod 71 is inclined and its output end is spherically hinged to the corresponding first electric push rod 7. When the output end of the second electric push rod 71 extends, it pushes the first electric push rod 7 to deflect obliquely outward.

[0066] When the sliding rail 3 is tilted laterally away from the support plate 42, the operator controls the output end of the second electric push rod 71 to extend, pushing the first electric push rod 7 to rotate away from the support plate 42. Then, the output end of the first electric push rod 7 is extended, so that the roller 2 on the first electric push rod 7 contacts the slope and is supported on the slope. At this time, the sliding rail 3 and the first electric push rod 7 are in a triangular rotation state in the lateral direction. The first electric push rod 7 supports the sliding rail 3 and prevents the sliding rail 3 from tilting too much in the direction away from the support plate 42 and tipping over laterally. Similarly, when the sliding rail 3 is tilted in the longitudinal direction, the output end of the second electric push rod 71 pushes the two first electric push rods 7 to rotate in a direction away from each other. Then, the output ends of the first electric push rods 7 are extended by different lengths, so that the roller 2 contacts the slope and is supported on the slope, preventing the invention from tipping over in the longitudinal direction.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
