[0001] The present invention relates to the technical field of coal mine drilling rigs, and particularly to a directional drilling rig for attitude adjustment of coal mine drilling holes. Background Art

[0002] Directional drilling rigs are widely used in coal mines underground, and can achieve flexible drilling, high-speed drilling and precise positioning, making coal mine mining more convenient, efficient and precise.

[0003] Due to the narrow space in coal mine shafts, when the directional drilling rigs in the prior art pass through bends in coal mine shafts, due to the relatively long overall body of the directional drilling rigs, it is difficult for the directional drilling rigs to quickly pass through the corners, and it is necessary for the staff to continuously adjust the attitude of the directional drilling rigs, which is time-consuming and laborious. Since the directional drilling rigs need to frequently move positions, and water and electricity lines need to be laid on the top of the coal mine shafts, when moving the directional drilling rigs, it is necessary to completely reset the directional drilling rigs in order to avoid the directional drilling rigs catching the water and electricity lines and causing damage to the water and electricity lines, resulting in low work efficiency.

[0018] 3. Through the design of the driving component of the present invention, the two wire protection plates can be conveniently combined. Through the design of the movable plate, it can effectively prevent the wire protection plate from hard squeezing the water and electricity lines when the water and electricity lines on the coal mine roof are relatively dense, resulting in damage to the water and electricity lines.

Detailed implementation manners

[0031] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but do not limit the present invention.

[0032] Embodiment 1: A directional drilling rig for attitude adjustment of coal mine drilling holes, as Figures 1-2 shown, which includes a bottom plate 1. A directional drilling rig 100 is installed on the top of the bottom plate 1. Two groups of crawlers 200 are symmetrically arranged on the lower side of the bottom plate 1. It also includes an inclination mechanism. The inclination mechanism includes a first frame 201. A first frame 201 and a second frame 202 which are hinged to each other are arranged on the lower side of the bottom plate 1. The two groups of crawlers 200 are respectively connected to the first frame 201 and the second frame 202. Hydraulic oil pumps 203 are symmetrically hinged on one side of the first frame 201. Telescopic shafts 204 are symmetrically hinged on the side of the second frame 202 close to the first frame 201. The telescopic shafts 204 are coaxially arranged with the corresponding hydraulic oil pumps 203. The telescopic ends of the telescopic shafts 204 slide through the hydraulic oil pumps 203 and are fixedly connected with pistons 2041. The pistons 2041 are slidably connected with the inner walls of the hydraulic oil pumps 203. It also includes a detection mechanism for detecting the height of the coal mine roof. The detection mechanism includes contact rods 205. Contact rods 205 are symmetrically arranged on the upper sides of the first frame 201 and the second frame 202. It also includes a wire protection mechanism for protecting the water and electricity lines on the coal mine roof. The wire protection mechanism includes wire protection plates 206. Wire protection plates 206 are symmetrically arranged on the upper side of the bottom plate 1.

[0033] As Figure 2 shown, the inclination mechanism also includes an oil distribution box 301. An oil distribution box 301 is communicated with the outer wall side of the hydraulic oil pump 203. Sliding seats 302 are slidably connected in both the first frame 201 and the second frame 202. An installation seat 303 is hinged on the sliding seat 302. One end of a universal shaft is hinged on the installation seat 303. The other end of the universal shaft is fixedly connected with a hydraulic rod 304. A pipeline for oil transmission is jointly communicated between the fixed end of the hydraulic rod 304 and the oil distribution box 301. When the piston 2041 slides inside the hydraulic oil pump 203, it can make the hydraulic oil in the hydraulic oil pump 203 enter the hydraulic rod 304 through the oil distribution box 301 and the pipeline for oil transmission. The telescopic end of the hydraulic rod 304 is hinged with an adapter seat 305. The adapter seat 305 is rotatably connected with the bottom of the bottom plate 1.

[0034] As Figures 3-4 shown, it also includes a switching mechanism. The switching mechanism includes an oil distribution plate 401. An oil distribution plate 401 is horizontally slidably connected in the oil distribution box 301. By moving the position of the oil distribution plate 401, the hydraulic oil in the hydraulic oil pump 203 can enter different hydraulic rods 304. A sealing frame 402 is fixedly connected to the top of the oil distribution plate 401. A chute for cooperating with the sealing frame 402 is penetrated and opened at the top of the oil distribution box 301. The sealing frame 402 can prevent the hydraulic oil from overflowing from the chute at the top of the oil distribution box 301. A first limit pin 403 is vertically slidably connected to one side of the sealing frame 402. Limit grooves for cooperating with the first limit pin 403 are symmetrically opened at the top of the oil distribution box 301.

[0035] AsFigures 5-6 As shown, it further includes a clamping mechanism. The clamping mechanism includes a first L-shaped plate 501. The tops of the first frame 201 and the second frame 202 are symmetrically and slidably connected with the first L-shaped plate 501. A first elastic member is provided between the first L-shaped plate 501 and the first frame 201 and the second frame 202 respectively. The first elastic member is a compression spring. On the mutually remote sides of two adjacent first L-shaped plates 501, a latch 502 is fixedly connected. Four uniformly distributed connecting rods 503 are fixedly connected to the bottom of the bottom plate 1. The four connecting rods 503 are arranged in one-to-one correspondence with the four first L-shaped plates 501. A plug hole for cooperating with the latch 502 is penetratingly formed on one side of the connecting rod 503, and the latch 502 is inserted into the plug hole.

[0036] As Figures 5-6 shown, it further includes an elastic slider 601. The first frame 201 and the second frame 202 are both symmetrically and vertically slidably connected with the elastic slider 601. The elastic slider 601 is used in cooperation with the first L-shaped plate 501, and the elastic slider 601 is used to limit the position of the first L-shaped plate 501.

[0037] As Figures 5-6 shown, it further includes an elastic telescopic rod 602. One side of the elastic slider 601 is fixedly connected with the elastic telescopic rod 602. The outer wall of the elastic telescopic rod 602 is respectively penetratingly and vertically slidably connected with the first frame 201 and the second frame 202. The telescopic end of the elastic telescopic rod 602 is fixedly connected with a rectangular plate for cooperating with the connecting rod 503. The outer wall of the telescopic end of the elastic telescopic rod 602 is penetratingly slidably connected with a second limit pin 603. The top of the fixed end of the elastic telescopic rod 602 is fixedly connected with a vertical plate 604 for cooperating with the second limit pin 603. Through the cooperation of the second limit pin 603 and the vertical plate 604, when the rectangular plate of the elastic telescopic rod 602 is squeezed, the elastic slider 601 can be made to no longer limit the first L-shaped plate 501.

[0038] Initially, the first elastic member is in a released state, the four elastic sliders 601 are all in a contracted state, the top surface of the elastic slider 601 contacts the bottom surface of the corresponding first L-shaped plate 501, the second limit pin 603 does not contact the corresponding vertical plate 604, the elastic telescopic rod 602 can telescopically move, the telescopic end of the elastic telescopic rod 602 drives the rectangular plate thereon to contact the bottom of the corresponding connecting rod 503, the latches 502 are respectively inserted into the jacks of the adjacent connecting rods 503, and the four connecting rods 503 are restricted to keep the bottom plate 1 in a horizontal state. When the directional drilling rig 100 needs to move in a straight line or make a small-angle turning movement, the movement of the directional drilling rig 100 can be realized through the two sets of crawlers 200.

[0039] When the directional drilling rig 100 needs to pass through a bend inside a coal mine and the bend radius is small, it is divided into two cases. In the first case, with the front side of the first frame 201 as the moving direction of the directional drilling rig 100, first, the staff move the two first L-shaped plates 501 inside the second frame 202 closer to each other. The first elastic member is stressed and contracts. The first L-shaped plate 501 drives the pin 502 to disengage from the insertion hole of the adjacent connecting rod 503 and no longer contacts the top of the corresponding elastic slider 601. The elastic slider 601 is released from the restriction and slides upward. After the elastic slider 601 slides, the side wall of the elastic slider 601 contacts the side wall of the corresponding first L-shaped plate 501. The first L-shaped plate 501 is restricted and cannot be reset, and its corresponding first elastic member remains in a contracted state. Moreover, when the elastic slider 601 slides upward, it drives the elastic telescopic rod 602 to lift and slide. The fixed end of the elastic telescopic rod 602 drives the vertical plate 604 to lift upward. Since the elastic force of the elastic slider 601 is greater than the elastic force of the elastic telescopic rod 602 and the rectangular plate cannot move at this time, the telescopic end of the elastic telescopic rod 602 contracts. The elastic slider 601 maintains a stable height and limits the first L-shaped plate 501. Through the above steps, the bottom plate 1 can rotate with the connection between the two connecting rods 503 at the front or rear side and the pin 502 as the center, so as to facilitate the subsequent upward lifting and tilting of the bottom plate 1.

[0040] Initially, the bottom end of the first limit pin 403 is snapped into the limit groove on the right side of the top of the corresponding oil distribution box 301. The oil pipeline between the oil distribution box 301 and the hydraulic rod 304 at the rear side of the second frame 202 is in a disconnected state, and the oil pipeline between the oil distribution box 301 and the hydraulic rod 304 at the front side is in a connected state. When the directional drilling rig 100 needs to turn right, the staff controls the movement of the two groups of crawlers 200 to move the first frame 201 and the second frame 202, and makes the first frame 201 and the second frame 202 rotate relative to each other with the hinge joint between them as the center. A V-shaped angle is formed between the right walls of the first frame 201 and the second frame 202. At this time, the two hydraulic oil pumps 203 and the two telescopic shafts 204 rotate horizontally with the connection points between the first frame 201 and the second frame 202 as the centers respectively. The hydraulic oil pump 203 and the corresponding telescopic shaft 204 always remain in a coaxial state. Under the action of the relative rotation of the first frame 201 and the second frame 202, the distance between the left hydraulic oil pump 203 and the fixed end of the corresponding telescopic shaft 204 increases, and the telescopic end of the left telescopic shaft 204 extends outward as the distance increases. The distance between the right hydraulic oil pump 203 and the fixed end of the corresponding telescopic shaft 204 decreases. It should be noted that at this time, the telescopic end of the right telescopic shaft 204 is in a contracted state. The telescopic end of the right telescopic shaft 204 drives the piston 2041 to slide inside the corresponding hydraulic oil pump 203, so that the hydraulic oil in the right hydraulic oil pump 203 enters the front hydraulic rod 304 through the oil distribution box 301 and the oil pipeline. The telescopic end of the front hydraulic rod 304 extends and presses on the bottom plate 1 through the connection seat 305. The bottom plate 1 rotates upward with the connection points between the two front connecting rods 503 and the two pins 502 as the center. After the bottom plate 1 rotates upward, it drives the directional drilling rig 100 to be in an inclined state. The horizontal length of the bottom plate 1 and the directional drilling rig 100 shortens. While the bottom plate 1 is lifted and tilted upward, it drives the two rear connecting rods 503 to be lifted upward, so that the connecting rods 503 no longer contact the rectangular plates of the corresponding elastic telescopic rods 602. The telescopic ends of the two rear elastic telescopic rods 602 are released and reset. And the bottom plate 1 exerts a pulling force on the rear hydraulic rod 304 through the rear connection seat 305. Due to the characteristics of the hydraulic rod 304, the telescopic end of the rear hydraulic rod 304 cannot extend. The telescopic end of the rear hydraulic rod 304 exerts a pulling force on its fixed end. The fixed end of the rear hydraulic rod 304 exerts a pulling force on the sliding seat 302 through the mounting seat 303. The sliding seat 302 slides along the length direction of the second frame 202 under the force. At this time, the length direction of the bottom plate 1 is the same as the length direction of the first frame 201, and the length direction of the bottom plate 1 is misaligned with the length direction of the second frame 202. Thus, the rear connection seat 305 rotates with the connection point of the bottom plate 1 as the center, and the fixed end of the rear hydraulic rod 304 drives the universal shaft to rotate with the connection point of the mounting seat 303 as the center. It should be noted that the smaller the angle of the V-shaped angle formed by the right walls of the first frame 201 and the second frame 202, the longer the distance that the right hydraulic oil pump 203 and the telescopic shaft 204 move closer to each other.Furthermore, the longer the telescopic end of the front hydraulic rod 304 extends, the larger the upward rotation angle of the bottom plate 1, so that the smaller the turning radius of the directional drilling rig 100 passing through the bend, the larger the upward rotation angle of the bottom plate 1, and the shorter the horizontal length between the bottom plate 1 and the directional drilling rig 100. There is no need for the staff to control the angle of the bottom plate 1, effectively improving the moving efficiency of the directional drilling rig 100. By shortening the horizontal length between the bottom plate 1 and the directional drilling rig 100, it is convenient for the bottom plate 1 and the directional drilling rig 100 to pass through the bend.

[0041] When the directional drilling rig 100 needs to turn left, repeat the above steps to form a V-shaped angle between the left wall of the first frame 201 and the second frame 202, and make the hydraulic oil in the left hydraulic oil pump 203 enter the inside of the front hydraulic rod 304 through the oil distribution box 301 and the oil pipeline, then the same effect as the above steps can be achieved.

[0042] The second case is that the directional drilling rig 100 moves in the direction of the rear side of the second frame 202. First, the staff moves the two first L-shaped plates 501 in the first frame 201 closer to each other, so that the elastic slider 601 is released from the restriction and slides upward, and limits the adjacent first L-shaped plate 501. When the directional drilling rig 100 needs to turn right, first adjust the position of one of the oil distribution plates 401. First, the staff lifts the first limit pin 403 upward, so that the first limit pin 403 disengages from the limit groove on the right side of the top of the oil distribution box 301. The release of the first limit pin 403 enables the seal frame 402 to move. Then push the seal frame 402 to the left. The seal frame 402 drives the oil distribution plate 401 to slide to the left. Subsequently, the first limit pin 403 aligns with the limit groove on the left side of the top of the oil distribution box 301, and the first limit pin 403 is inserted into the limit groove on the left side of the top of the oil distribution box 301. At this time, the oil pipeline between the oil distribution box 301 and the front hydraulic rod 304 is disconnected, and the oil pipeline between the oil distribution box 301 and the rear hydraulic rod 304 is connected. Then the staff controls the movement of the two groups of crawlers 200 to move the first frame 201 and the second frame 202, and makes the first frame 201 and the second frame 202 rotate around their hinge point. A V-shaped angle is formed between the right walls of the first frame 201 and the second frame 202. Furthermore, the hydraulic oil in the right hydraulic oil pump 203 enters the inside of the front hydraulic rod 304 through the oil distribution box 301 and the oil pipeline, and then repeating the above steps can achieve the same effect.

[0043] When the directional drilling rig 100 exits the bend, first, the staff determines whether the directional drilling rig 100 requires consecutive bends. When the directional drilling rig 100 needs to pass through consecutive bends, no adjustment is required, and it can continue to move. During the process of the directional drilling rig 100 exiting the bend, the length directions of the first frame 201 and the second frame 202 gradually align. During this process, the distance between the left or right hydraulic oil pump 203 and the fixed end of the corresponding telescopic shaft 204 increases or decreases accordingly until it is reset. Taking the front hydraulic rod 304 and the right hydraulic oil pump 203 as an example, during the process of exiting the bend, the distance between the right hydraulic oil pump 203 and the corresponding telescopic shaft 204 increases, and the thrust of the telescopic end of the telescopic shaft 204 on the hydraulic oil inside the hydraulic oil pump 203 decreases. The hydraulic oil reduces the thrust on the telescopic end of the front hydraulic rod 304. The telescopic end of the front hydraulic rod 304 is squeezed by the weight of the bottom plate 1 and the directional drilling rig 100, causing the telescopic end of the front hydraulic rod 304 to contract and reset. The bottom plate 1 rotates and resets with the connection point of the two front connecting rods 503 and the two pins 502 as the center. The two rear connecting rods 503 descend and reset. At this time, the two rear connecting rods 503 contact and squeeze the rectangular plate on the corresponding elastic telescopic rod 602. The rectangular plate is stressed and drives the telescopic end of the elastic telescopic rod 602 to contract and slide. The telescopic end of the elastic telescopic rod 602 contracts. Since the elastic force of the elastic telescopic rod 602 is less than the elastic force of the elastic slider 601, the elastic slider 601 remains stable at this time and keeps limiting the adjacent first L-shaped plate 501. When passing through subsequent bends, the same effect can be achieved by repeating the above steps.

[0044] When the directional drilling rig 100 no longer continuously passes through the bend after coming out of the bend, taking the two elastic telescopic rods 602 on the front side as an example, after the two connecting rods 503 on the front side no longer contact the rectangular plates of the two elastic telescopic rods 602, the staff lift the telescopic ends of the elastic telescopic rods 602 upward, so that the telescopic ends of the elastic telescopic rods 602 extend upward. The telescopic ends of the elastic telescopic rods 602 drive the corresponding second limit pins 603 to lift upward until the bottom surface of the second limit pin 603 crosses the top surface of the corresponding vertical plate 604. Then, the staff push the second limit pin 603 backward so that the bottom surface of the second limit pin 603 contacts the top surface of the corresponding vertical plate 604. Then, repeat the above steps to make the two connecting rods 503 on the front side land and reset. The connecting rod 503 contacts and presses the rectangular plate on the corresponding elastic telescopic rod 602. The rectangular plate is stressed and drives the telescopic end of the elastic telescopic rod 602 to land. The telescopic end of the elastic telescopic rod 602 presses the vertical plate 604 through the second limit pin 603. The vertical plate 604 is stressed and drives the fixed end of the elastic telescopic rod 602 to land. The fixed end of the elastic telescopic rod 602 drives the corresponding elastic slider 601 to contract and slide. Subsequently, the side wall of the elastic slider 601 no longer contacts the side wall of the corresponding first L-shaped plate 501. The first elastic member is released to drive the first L-shaped plate 501 to slide and reset. The first L-shaped plate 501 drives the plug pin 502 to insert into the jack of the corresponding connecting rod 503, thereby completing the reset of the first L-shaped plate 501. At this time, the two connecting rods 503 on the front side and the two connecting rods 503 on the rear side are matched with the corresponding movable plug pins 502, so that the bottom plate 1 and the directional drilling rig 100 are kept in a horizontal state, and the first frame 201 and the second frame 202 are in the same vertical plane, preventing the first frame 201 and the second frame 202 from rotating during movement, resulting in the upward lift of the bottom plate 1 and the directional drilling rig 100.

[0045] Embodiment 2: As Figures 7-8 With Figure 10As shown, the detection mechanism further includes a support frame 701. Support frames 701 are symmetrically connected to both sides of the directional drill 100. The support frame 701 is connected to the hydraulic system of the directional drill 100 (the hydraulic system is a prior art and is not shown in the figure and will not be elaborated here). When the hydraulic system of the directional drill 100 adjusts the angle of the directional drill 100, the support frame 701 moves synchronously. The tops of the two support frames 701 on the same side are hinged to the corresponding wire protection plate 206. A vertical rod 702 is fixedly connected to the middle of the support frame 701. An irregular-shaped groove is formed through the top of the vertical rod 702. A detection rod 703 is slidably connected in the irregular-shaped groove. A second elastic member is provided between the detection rod 703 and the irregular-shaped groove. The second elastic member is a return spring. A vertical groove is formed at the top of the detection rod 703. The bottom end of the contact rod 205 is clamped into the vertical groove and slides therein. A third elastic member is provided between the contact rod 205 and the vertical groove. The third elastic member is a compression spring. A pressure sensor 704 that cooperates with the contact rod 205 is fixedly connected in the vertical groove of the detection rod 703.

[0046] As Figures 7-9 shown, the wire protection mechanism further includes a second L-shaped plate 801. Second L-shaped plates 801 are fixedly connected to both sides of the bottom plate 1. A driving assembly 802 is connected to the second L-shaped plate 801, and a guide shaft is fixedly connected. The driving assembly 802 is composed of a lead screw and a handwheel. The bottom end of the lead screw penetrates and is rotatably connected to the second L-shaped plate 801, and the handwheel is fixedly connected to the bottom end of the lead screw. A long rod 803 is sleeved on the guide shaft. The two ends of the long rod 803 are respectively slidably sleeved on the outer walls of the adjacent vertical rods 702. The long rod 803 is threadedly connected to the lead screw in the driving assembly 802. T-shaped rods 804 are symmetrically fixedly connected to the top of the long rod 803. One end of a T-shaped rod 804 is rotatably connected to a first connecting rod 805, and the first connecting rod 805 is hinged to the wire protection plate 206.

[0047] As Figure 8 and Figure 9 shown, the wire protection mechanism further includes a second connecting rod 901. Second connecting rods 901 are symmetrically rotatably connected to the T-shaped rods 804. One end of a protruding shaft is fixedly connected to one side of the second connecting rod 901. One end of the protruding shaft is fixedly connected to the detection rod 703. The protruding shaft is clamped into the irregular-shaped groove of the vertical rod 702 and slides therein. When the long rod 803 descends and slides, the second connecting rod 901 can drive the detection rod 703 to descend through the protruding shaft.

[0048] As Figure 8 With Figure 11 shown, the wire protection mechanism further includes a movable plate 1001. Movable plates 1001 are symmetrically hinged to the wire protection plates 206. A ball is rotatably connected to the top end of the contact rod 205. The movable plate 1001 cooperates with the ball at the top end of the contact rod 205. The movable plate 1001 is used to contact the hydroelectric lines on the coal mine roof.

[0049] When the directional drilling rig 100 is working, it is usually necessary to adjust the angle of the drill pipe of the directional drilling rig 100 to make the drill pipe tilt upward or downward, so as to facilitate the directional drilling rig 100 to drill holes. After the directional drilling rig 100 completes a drilling operation, it needs to move to the next location for drilling. At this time, there is no need to reset the directional drilling rig 100, and the staff judges the on-site environment, which is divided into two situations. The first situation is that there are no water and electricity lines laid on the coal mine roof. At this time, directly control the two groups of crawlers 200 to drive the bottom plate 1 and the directional drilling rig 100 to move. When the height of the coal mine roof drops to the contact rod 205, the ball at the top of the contact rod 205 contacts the coal mine roof and rolls under the action of friction. Since the coal mine roof is uneven, the ball drives the contact rod 205 to slide up and down in the vertical groove of the detection rod 703 with the undulation of the unevenness. The third elastic member continuously contracts and releases. Since the elastic force of the second elastic member is greater than the elastic force of the third elastic member, the second elastic member can drive the detection rod 703 to remain stable during the contraction of the third elastic member. When the bottom end of the contact rod 205 contacts and presses the pressure sensor 704, it means that the directional drilling rig 100 is extremely likely to collide with the coal mine roof at this time. At this time, the pressure sensor 704 controls the hydraulic system of the directional drilling rig 100 to adjust, so that the hydraulic system drives the directional drilling rig 100 to reduce the tilt angle, thereby effectively preventing the directional drilling rig 100 from colliding with the coal mine roof and causing damage to the directional drilling rig 100. When the contact rod 205 no longer contacts the pressure sensor 704, the hydraulic system of the directional drilling rig 100 is adjusted to restore the tilt angle of the directional drilling rig 100. This can save a lot of time and improve work efficiency.

[0050] The second case is that there are water and electricity lines laid on the roof of the coal mine. Due to the unevenness of the roof of the coal mine, the laid water and electricity lines will sag. Before the directional drilling rig 100 moves, the staff first drives the handwheel of the driving assembly 802. The handwheel drives the lead screw to rotate. The lead screw drives two adjacent T-shaped rods 804 to descend through the long rod 803. The T-shaped rod 804 exerts a pulling force on the adjacent wire protection plate 206 through the first connecting rod 805. The wire protection plate 206 rotates upward around the connection point of the support frame 701 under the force to be parallel to the bottom plate 1. The two adjacent movable plates 1001 rotate synchronously with the corresponding wire protection plates 206. At the same time, the T-shaped rod 804 exerts a pulling force on the detection rod 703 through the second connecting rod 901 and the protruding shaft. The detection rod 703 and the protruding shaft slide vertically downward along the special-shaped groove under the force, and the second elastic member is compressed. The detection rod 703 drives the contact rod 205 to descend vertically through the third elastic member, so that the detection rod 703 and the contact rod 205 avoid the rotation trajectory of the movable plate 1001, thereby preventing the movable plate 1001 from colliding with the detection rod 703 when it rotates. It should be noted that when the movable plate 1001 rotates to be about to be parallel to the bottom plate 1, the ball at the top of the contact rod 205 is higher than the bottom surface of the adjacent movable plate 1001. The movable plate 1001 contacts the ball at the top of the adjacent contact rod 205, and the ball squeezes the movable plate 1001, so that the movable plate 1001 rotates around the connection point of the wire protection plate 206, making one end of the movable plate 1001 higher than the top surface of the wire protection plate 206. At this time, the two wire protection plates 206 are combined into a flat surface. During the movement of the directional drilling rig 100, the two wire protection plates 206 can lift the water and electricity lines, thus effectively preventing the detection rod 703 from hanging up the water and electricity lines. When the water and electricity lines are relatively dense, the hard extrusion of the two wire protection plates 206 on the water and electricity lines will cause damage to the water and electricity lines. At this time, the two movable plates 1001 on the wire protection plate 206 contact the water and electricity lines, and the water and electricity lines squeeze the movable plates 1001, so that the movable plates 1001 squeeze the balls on the contact rod 205. The balls drive the contact rod 205 to slide downward, so that the contact rod 205 descends. The third elastic member is compressed. Subsequently, the bottom end of the contact rod 205 contacts and squeezes the pressure sensor 704, and then the hydraulic system of the directional drilling rig 100 adjusts the inclination angle of the directional drilling rig 100. When the two movable plates 1001 no longer contact the water and electricity lines, the third elastic member releases and drives the contact rod 205 to slide back to its original position, and the hydraulic system of the directional drilling rig 100 makes adjustments to restore the inclination angle of the directional drilling rig 100.

[0051] After the directional drilling rig 100 moves to a suitable position, the operator rotates the handwheel in the driving assembly 802, so that the long rod 803 is lifted upward to slide and reset. The long rod 803 drives the two T-shaped rods 804 thereon to be lifted upward to slide and reset, so that the contact rod 205 is lifted upward to reset. The second elastic member is released, and the wire protection plate 206 drives the two movable plates 1001 thereon to rotate and reset. Then, the directional drilling rig 100 can be started for drilling work.
