Description

Technical Field

[0001] The present invention relates to the field of mining exploration equipment, in particular to a crawler-type fully hydraulic directional drilling rig for coal mines. Background Art

[0002] Crawler-type fully hydraulic directional drilling rig is mainly used for directional drilling construction in coal mines, such as long drilling along coal seams, gas extraction holes, grouting and fire prevention, coal seam water injection, water exploration and drainage, coal seam thickness detection, and sudden relief and pressure relief. The crawler-type fully hydraulic directional drilling rig is mainly composed of a power unit and hydraulic system, a crawler walking mechanism, a drill frame and thruster, a drill rod connecting and unloading device, an anchoring device and an operation control system.

[0003] At present, the drill rod loading and unloading device installed on the crawler walking mechanism is mainly used to replace manual loading and unloading of drill rods. The drill rods are arranged in a matrix inside the drill rod rack. The drill rods are taken one by one to the inside of the loading structure through the grabbing structure set on the upper part of the drill rod rack, and then the drill rods are moved to the position of the drill rack through the loading structure, thereby completing the automatic loading of the drill rods.

[0004] However, due to the limited space inside the mine, the grabbing structure installed on the upper part of the drill rod rack increases the overall height of the directional drilling rig, making it impossible for the directional drilling rig to enter a relatively narrow mine to operate, thereby reducing the adaptability of the directional drilling rig. In addition, when the directional drilling rig is operating, the drill rack is usually required to tilt at a certain angle, which causes the loading structure installed on the drill rack to tilt synchronously, making it difficult to ensure that the drill rod is fixed in a fixed position inside the loading structure when the grabbing structure transfers the drill rod to the loading structure, which can easily cause the drill rod to get stuck on the drill rack or thruster when the loading structure transports the drill rod.

DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0033] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5 A crawler-type fully hydraulic directional drilling rig for coal mines includes a crawler vehicle assembly 1, a drilling rig assembly 2 is provided at the front upper part of the crawler vehicle assembly 1, a storage mechanism 3 is provided at the rear upper part of the crawler vehicle assembly 1, and a loading mechanism 4 is provided at the middle upper part of the crawler vehicle assembly 1 for placing the drill rods inside the storage mechanism 3 one by one inside the drilling rig assembly 2.

[0034] When a directional drill is needed to operate inside a mine, the drill assembly 2 is first moved to the designated operating position by the crawler vehicle assembly 1, and then drilling is performed by the drill assembly 2. At the same time, the drill rod in the storage mechanism 3 is automatically added to the interior of the drill assembly 2 by the loading mechanism 4.

[0035] See Figure 1 and Figure 2 The storage mechanism 3 includes a silo 31 fixedly mounted on the upper right rear part of the crawler vehicle assembly 1. A continuously bent serpentine material channel 32 is provided inside the silo 31. The lower end of the serpentine material channel 32 is located at the front lower side of the silo 31 and is connected to the outside. An opening and closing component 33 for controlling the discharge of drill rods one by one is provided on the silo 31.

[0036] See Figure 2 and Figure 4 The opening and closing assembly 33 includes two baffles 331 arranged front and back on the front side of the lower part of the silo 31, which slide up and down. The distance between the two baffles 331 is equal to the outer diameter of the drill pipe, and the rear baffle 331 is located on the upper part of the front baffle 331. An electric push rod 332 is fixedly installed on the right side of the silo 31, and the telescopic section of the electric push rod 332 is fixedly connected to the two baffles 331 at the same time.

[0037] A plurality of drill rods are added to the interior of the silo 31 in advance, so that the drill rods are arranged inside the serpentine channel 32, and the drill rods have a tendency to roll downward along the serpentine channel 32 under the action of gravity, which makes the drill rods arranged closely together one by one inside the serpentine channel 32. In the initial state, the telescopic section of the electric push rod 332 is in a retracted state, so that the electric push rod 332 drives the two baffles 331 to be in the upper position, so that the front baffle 331 blocks the lower end of the serpentine channel 32 to prevent the drill rods from leaking.

[0038] See Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The feeding mechanism 4 includes a lifting assembly 41 arranged in the middle of the upper side of the crawler vehicle assembly 1, and the lifting assembly 41 is connected to a material rack 43 through a flip assembly 42. The part of the material rack 43 away from the flip assembly 42 is a C-shaped structure. The middle part of the C-shaped structure of the material rack 43 is provided with three roller racks 40 that slide radially along the C-shaped structure of the material rack 43 at equal intervals along its circumference. The roller rack 40 is rotatably provided with a supporting roller 44 on one side of the roller rack 40 close to the axis of the C-shaped structure of the material rack 43. A receiving plate 431 for receiving the rolling of the drill rod is fixedly installed on the C-shaped structure of the material rack 43.

[0039] like Figure 3 As shown, in the initial state, the opening of the C-shaped structure of the material picking rack 43 is located at the lower part of the silo 31, and the opening of the C-shaped structure of the material picking rack 43 is in a vertically upward state, so that the material picking rack 43 drives the receiving plate 431 thereon to be at the lower front side of the lower end of the serpentine material channel 32.

[0040] When a drill rod needs to be added to the drilling rig assembly 2, the telescopic section of the electric push rod 332 is extended to drive the two baffles 331 to move downward at the same time, so that the rear baffle 331 blocks the second drill rod from the bottom to the top. When the front baffle 331 is completely moved to the lower part of the first drill rod from the bottom to the top, the first drill rod from the bottom to the top rolls forward from the outside of the discharge bin 31 to the receiving plate 431 under the action of gravity, and then the drill rod rolls along the receiving plate 431 to the inside of the C-shaped structure of the material rack 43.

[0041] It should be noted that the hopper 31 is located directly behind the material rack 43, so that when the drill rod inside the hopper 31 rolls to the inside of the material rack 43, it can ensure that the drill rod is roughly located in the middle position of the material rack 43, thereby preventing the drill rod from sliding along its axial direction to the outside of the material rack 43.

[0042] Then, the telescopic section of the electric push rod 332 is retracted to drive the two baffles 331 to move to the initial position, so that the drill rods inside the silo 31 move downward along the serpentine channel 32 by a distance of the drill rod diameter under the action of gravity, thereby facilitating the discharge of the drill rods one by one.

[0043] See Figure 5 、 Figure 6 and Figure 7 , a weighing scale 46 is fixedly installed on the inner wall of the C-shaped structure of the material reclaimer 43 and on the left and right sides of its opening position. A moving component 45 for moving the drill rod by abutting the roller 44 is provided on the material reclaimer 43. The moving component 45 includes an arc-shaped plate 455 that is slidably arranged on the outside of the C-shaped structure of the material reclaimer 43. A follower column 454 is fixedly installed on the side of the roller frame 40 away from the axis of the C-shaped structure of the material reclaimer 43. A driving plate 456 corresponding to the roller frame 40 is fixedly installed on the right side of the arc-shaped plate 455. A sliding groove is provided on the driving plate 456 to cooperate with the corresponding notch of the follower column 454.

[0044] See Figure 6 and Figure 7 The sliding groove of the driving plate 456 gradually tilts from left to right toward the direction close to the C-shaped structural axis of the material picking rack 43. A second hydraulic rod 457 is arranged between the arc plate 455 and the material picking rack 43. A driving motor 458 is fixedly installed on one of the roller frames 40 to drive the corresponding abutting roller 44 to rotate.

[0045] When the drill rod is located inside the C-shaped structure of the material rack, the telescopic section of the No. 2 hydraulic rod 457 is extended to drive the arc plate 455 to move to the left. The arc plate 455 pushes the three roller frames 40 to move simultaneously toward the direction close to the axis of the C-shaped structure of the material rack through the driving plate 456, so that the roller frames 40 drive the abutting roller 44 to abut against the cylindrical surface of the drill rod. At this time, the drill rod is supported by the abutting roller 44 located at the opening of the C-shaped structure corresponding to the material rack, so that the parts of the drill rod located on the left and right sides of the abutting roller 44 are pressed on the two corresponding weighing scales 46 under the action of gravity.

[0046] The gravity acting on the parts of the drill rod located on the left and right sides of the abutment roller 44 is detected by two weighing meters 46. When the part of the drill rod located on the right side of the abutment roller 44 is larger, the value detected by the weighing meter 46 on the right side increases. Then the drive motor 458 is started to drive the abutment roller 44 corresponding to the opening of the C-shaped structure of the material rack 43 to rotate, so that the abutment roller 44 drives the drill rod to move to the left until the gravity values detected by the two weighing meters 46 are consistent, indicating that the drill rod is now located in the center position of the C-shaped structure of the material rack 43, and vice versa.

[0047] It should be noted that, since the three roller frames 40 are evenly distributed in the middle of the C-shaped structure of the material reclaiming frame 43, and the remaining two roller frames 40 are symmetrically distributed relative to the roller frame 40 facing the opening of the C-shaped structure of the material reclaiming frame 43, and the weighing scale 46 is located on the left and right sides of the roller frame 40 facing the opening of the C-shaped structure of the material reclaiming frame 43, the extrusion force generated by the abutting rollers 44 on the remaining two roller frames 40 on the drill rod will not act on the weighing scale 46. To take a step back, even if the extrusion force generated by the two abutting rollers 44 on the drill rod acts on the weighing scale 46, since the two abutting rollers 44 are symmetrically distributed, the extrusion force generated is also symmetrical, and will not affect the difference in gravity values detected by the left and right weighing scales 46, and thus will not affect the judgment of whether the drill rod is centered.

[0048] See Figure 5 、 Figure 8 and Figure 9 , arc frames 47 are fixedly installed on the left and right sides of the material picking rack 43C-shaped structure, and a synchronization component 48 is provided on the arc frame 47. The synchronization component 48 includes three sliding members 481 that are arranged at equal intervals along the circumference of the arc frame 47 and slide radially along the arc frame 47. The sliding member 481 is rotatably connected to the side away from the material picking rack 43C-shaped structure with a rolling wheel 49.

[0049] See Figure 8 and Figure 9 Two connecting plates 482 are provided on the outer side of the arc frame 47 for radial sliding. The two connecting plates 482 are symmetrically arranged relative to the opening position of the C-shaped structure of the material reclaiming rack. The connecting plates 482 are slidably connected to the sliding members 481 at the corresponding positions on both sides of the connecting plates 482. A mounting plate 483 is commonly installed on the two sliding members 481 corresponding to the opening positions of the C-shaped structure of the material reclaiming rack. A No. 3 hydraulic rod 485 is provided between the mounting plate 483 and the C-shaped structure of the material reclaiming rack.

[0050] When the drill rod is located in the center position of the material rack 43C-shaped structure, the extended section of the No. 3 hydraulic rod 485 is retracted, so that the No. 3 hydraulic rod 485 drives the mounting plate 483 to move toward the direction close to the material rack 43C-shaped structure, and the mounting plate 483 drives the two sliding members 481 connected to it to move toward the direction close to the axis of the material rack 43C-shaped structure. At the same time, the two sliding members 481 connected to the mounting plate 483 drive the remaining sliding members 481 to move synchronously through the connecting plate 482 at the corresponding position, thereby causing all the sliding members 481 to move synchronously toward the direction close to the axis of the material rack 43C-shaped structure.

[0051] The sliding member 481 drives the rolling wheel 49 to synchronously press against the outer surface of the drill rod, so that the rolling wheel 49 pushes the drill rod to be centered, and the left and right positions of the drill rod are limited by clamping the rolling wheels 49 on both sides, and then the telescopic section of the No. 2 hydraulic rod 457 is extended to drive the abutment roller 44 to move to the initial position to prevent the abutment roller 44 from obstructing the rotation of the drill rod.

[0052] Continue reading Figure 8 and Figure 9 The mounting plate 483 is fixedly installed with a dual-axis motor 484 that drives two left and right opposite rolling wheels 49. The side of the sliding member 481 away from the material rack 43C-shaped structure is fixedly installed with a spring telescopic rod 486 through an extension plate. The side of the spring telescopic rod 486 close to the axis of the material rack 43C-shaped structure is fixedly installed with a scraping block 487 that rests on the cylindrical surface of the corresponding rolling wheel 49.

[0053] When the rolling wheel 49 rests against the outer surface of the drill rod, the dual-axis motor 484 is started to drive the two rolling wheels 49 in the corresponding positions to rotate, so that the rolling wheel 49 drives the drill rod to rotate, and at the same time the drill rod drives the remaining rolling wheels 49 to rotate synchronously, so that the rolling wheel 49 corrects its position by rotating the drill rod, so that the drill rod is located at the coaxial position of the material rack 43C-shaped structure. While the rolling wheel 49 rotates, the spring telescopic rod 486 drives the scraper block 487 to rest against the cylindrical surface of the rolling wheel 49 through its own elastic force, so that the scraper block 487 scrapes off the debris on the cylindrical surface of the rolling wheel 49, so that the position where the rolling wheel 49 pushes the drill rod to move is more accurate.

[0054] See Figure 1 、 Figure 3 and Figure 5 The lifting assembly 41 includes two fixed support plates 411 fixedly installed in the middle of the crawler vehicle assembly 1 and arranged symmetrically on the left and right. A sliding plate 412 is provided on the fixed support plate 411 for sliding in the vertical direction. A gear rack driven slide rail unit 413 is provided on the right side of the sliding plate 412 and the fixed support plate 411 on the right.

[0055] Continue reading Figure 1 、 Figure 3 and Figure 5 The flipping assembly 42 includes a flipping frame 421 that is rotated together and arranged between the two sliding plates 412. The upper part of the flipping frame 421 is hinged with an inclination plate 422, and the inclination plate 422 is fixedly connected to the material picking frame 43. A hydraulic rod 423 is hinged between the inclination plate 422 and the flipping frame 421. A reduction motor 424 that drives the flipping frame 421 to rotate is fixedly installed on the left side of the left sliding plate 412.

[0056] When the rolling wheel 49 pushes the drill rod to the coaxial position of the C-shaped structure of the material picking rack 43, the right sliding plate 412 is driven upward by the slide rail unit 413, and the right sliding plate 412 drives the material picking rack 43 to move upward to the position corresponding to the drilling rig assembly 2 through the flipping frame 421 and the tilting plate 422, and then the reduction motor 424 drives the flipping frame 421 to flip forward ninety degrees, and the flipping frame 421 drives the material picking rack 43 forward through the tilting plate 422, which makes the C-shaped structure opening of the material picking rack 43 face forward, and then the tilting plate 422 is lifted by extending the telescopic section of the No. 1 hydraulic rod 423, so that the angle of the material picking rack 43 is adjusted through the tilting plate 422, so that the material picking rack 43 drives the drill rod to move to the specified position inside the drilling rig assembly 2. At this time, the C-shaped structure opening of the material picking rack 43 faces straight ahead, and the axial direction of the C-shaped structure of the material picking rack 43 is parallel to the axial direction of the drilling rig assembly 2.

[0057] It should be noted that, since the elevation angle of the drilling rig assembly 2 remains fixed when drilling through the drill rod, it is only necessary to set the positions of the flip frame 421 and the tilt plate 422 in advance, and then the positions of the flip frame 421 and the tilt plate 422 remain unchanged, so there is no need to adjust the positions of the flip frame 421 and the tilt plate 422 in real time.

[0058] See Figure 1 、 Figure 3 and Figure 4 A feeding assembly 34 is provided on the left rear part of the upper side of the crawler vehicle assembly 1. The feeding assembly 34 includes through holes 341 arranged at equal intervals on the left side of the silo 31 along the trajectory of the serpentine material channel 32. A support plate 342 is provided on the left rear part of the upper side of the crawler vehicle assembly 1 for sliding left and right. Step holes 343 corresponding to the through holes 341 are provided on the support plate 342. The inner diameter of the left part of the stepped hole 343 is smaller than that of the right part. A push plate 345 is provided on the left rear part of the upper side of the crawler vehicle assembly 1 for sliding left and right. A push column 346 is fixedly installed on the right side of the push plate 345 and is slidably connected to the inside of the stepped hole 343 at the corresponding position.

[0059] The spare drill rod is placed in advance between the through hole 341 and the stepped hole 343 at the corresponding position. When all the drill rods inside the silo 31 are discharged, the operator manually pushes the support plate 342 to the right, so that the support plate 342 pushes the spare drill rod through the through hole 341 through the stepped hole 343 to the inside of the silo 31. When the support plate 342 is against the left side of the silo 31, the operator manually pushes the push plate 345 to the right, and the push plate 345 drives the push column 346 to pass through the through hole 341 and insert into the interior of the silo 31, so that the push column 346 pushes the spare drill rod completely to the inside of the silo 31.

[0060] Continue reading Figure 3 and Figure 4 Several groups of raised columns 344 corresponding to the through holes 341 are provided on the left side of the silo 31. Each group consists of two raised columns 344 fixedly installed on the left side of the silo 31 and arranged symmetrically in front and back. The raised columns 344 are located at the lower part of the corresponding through holes 341.

[0061] The operator manually moves the push plate 345 and the support plate 342 to the initial position, and then the operator manually inserts the drill rod into the stepped hole 343, so that the end of the drill rod close to the silo 31 is located at the upper part of each group of raised columns 344, and then moves the support plate 342 to the right to push the drill rod into the through hole 341, but does not allow the drill rod to extend into the silo 31, thereby completing the filling of the spare drill rod.

[0062] Continue reading Figure 3 and Figure 4 The upper part of the silo 31 is in a slope structure that gradually tilts downward from the front to the back, and the rear side of the upper part of the silo 31 is connected inside and outside.

[0063] After drilling is completed, the drill rod is loaded and unloaded, and the drill rod on the drilling rig assembly 2 is clamped and fixed by the rolling wheel 49. Then the flipping frame 421 drives the material picking frame 43 to flip 180 degrees, so that the C-shaped structure opening of the material picking frame 43 faces the rear, so that the material picking frame 43 moves the removed drill rod to the upper part of the silo 31, and then places the drill rod on the upper part of the silo 31, so that the drill rod automatically rolls along the inclined structure on the upper part of the silo 31 to the inside of the silo 31.

[0064] See Figures 1-9 When drilling a mine, the present invention also includes the following steps: First, the drilling rig assembly 2 is moved to the designated working position by the crawler vehicle assembly 1, and then drilling is performed by the drilling rig assembly 2. Then, the telescopic section of the electric push rod 332 is extended to drive the two baffles 331 to move downward at the same time, so that the drill rod rolls along the receiving plate 431 to the inside of the C-shaped structure of the material rack 43.

[0065] In the second step, the telescopic section of the No. 2 hydraulic rod 457 is extended to drive the abutment roller 44 to abut against the cylindrical surface of the drill rod, and the gravity of the parts of the drill rod located on the left and right sides of the abutment roller 44 is detected by two weighing meters 46, and the drill rod is driven by the driving motor 458 to move to the center position of the C-shaped structure of the material rack 43.

[0066] The third step is to retract the extended section of the No. 3 hydraulic rod 485 so that the rolling wheel 49 is synchronously pressed against the outer surface of the drill rod, and the drill rod is pushed to be centered by the rolling wheel 49, and the telescopic section of the No. 2 hydraulic rod 457 is retracted, and the dual-axis motor 484 is started to drive the drill rod to rotate, so that the rolling wheel 49 corrects its position by rotating the drill rod.

[0067] In the fourth step, the slide rail unit 413 and the reduction motor 424 drive the drill rod to move to a designated position inside the drilling rig assembly 2 , thereby placing the drill rod inside the drilling rig assembly 2 .

[0068] In the fifth step, the operator manually pushes the support plate 342 to the right to move the spare drill rod to the inside of the silo 31. When the support plate 342 rests against the left side of the silo 31, the operator manually pushes the push plate 345 to the right to push the spare drill rod completely to the inside of the silo 31 through the push column 346.

[0069] In the sixth step, after drilling is completed, the drill rod on the drilling rig assembly 2 is clamped and fixed by the rolling wheel 49, and then the flipping frame 421 drives the material picking frame 43 to flip 180 degrees, so that the material picking frame 43 places the removed drill rod on the upper part of the silo 31, so that the drill rod automatically rolls along the inclined structure on the upper part of the silo 31 to the inside of the silo 31.

[0070] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
