Description

Technical Field

[0001] This invention belongs to the field of coal mine tunnel drilling technology, and relates to directional drilling rigs, specifically to an advanced exploration integrated drilling rig suitable for tunnel excavation faces and its usage method. Background Technology

[0002] In coal mine roadway excavation, drilling exploratory boreholes at the working face is an essential process. These boreholes are used to detect potential geological hazards such as water, gas, and collapse columns ahead of the roadway, providing invaluable information. The borehole layout typically involves symmetrically arranging a certain number of boreholes on both sides of the roadway centerline to explore the geological conditions ahead. To increase the detection range, one or two boreholes at a certain angle to the roadway centerline are often placed near the left and right sidewalls. Figure 1 The "No. 1 Hole" in the project. The drilling depth of advance exploration boreholes is typically in the range of 90-200m, and the drilling rigs used are relatively large in both drilling capacity and size. Because the drilling rig vehicle has a certain width, and the drilling equipment for performing the drilling is usually located on the right side of the vehicle, the construction... Figure 1 When drilling holes like "No. 1 Hole," which have a certain angle and are close to the left side of the tunnel, the existing integrated drilling rigs must maintain a large distance from the borehole opening of the tunneling face. A large distance will cause the drill rod to sag under the action of gravity, making it difficult to open the hole. This undoubtedly increases the difficulty of drilling and the construction assistance time.

[0003] To increase tunneling efficiency, the width of the tunnel boring machine (TBM) and the tunnel is similar, leaving only a narrow passage for pedestrians or small materials. Therefore, the issue of passing between the advance drilling rig and the TBM becomes particularly prominent. Currently, there are roughly two methods. One method involves the TBM retracting to the connecting roadway closest to the working face when advance drilling is required. The advance drilling rig then travels to the working face to drill. After drilling, the advance drilling rig retracts behind the connecting roadway, and the TBM exits from the connecting roadway and proceeds to the working face for tunneling operations. The other method involves constructing a dedicated chamber at regular intervals along the side of the tunnel during tunneling to house the advance drilling rig, thus allowing for passing between the TBM and the advance drilling rig. However, both of these methods can negatively impact the overall efficiency of tunneling to some extent. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an advanced exploration integral drilling rig and its usage method suitable for tunnel excavation faces, and to solve the technical problems in the existing technology that the construction of advanced exploration boreholes in tunneling faces and the passing efficiency between the advanced exploration drilling rig and the tunneling machine need to be further improved.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0006] An advanced exploration integrated drilling rig suitable for tunnel excavation faces includes a vehicle body, which includes a left vehicle body and a right vehicle body. The left vehicle body includes a left vehicle body platform, and the right vehicle body includes a right vehicle body platform.

[0007] The rear end of the right vehicle platform is rotatably equipped with a staggered deployment mechanism, and the other end of the staggered deployment mechanism is fitted onto the left vehicle platform.

[0008] The left vehicle platform, driven by the offset deployment mechanism, can slide longitudinally relative to the right vehicle platform, achieving a sliding longitudinal offset.

[0009] The left vehicle platform can rotate and unfold longitudinally around the rear end of the right vehicle platform under the drive of the staggered unfolding mechanism.

[0010] The present invention also has the following technical features.

[0011] Furthermore, the left vehicle platform includes a left vehicle platform body, and the interior of the left vehicle platform body has a transverse sliding groove that runs horizontally from left to right. The length of the sliding groove is arranged along the longitudinal direction, and the left vehicle platform body below the sliding groove is a slide rail. A cylinder mounting boss is fixedly provided on the front part of the right side wall of the left vehicle platform body. The cylinder mounting boss is located at the longitudinal front end of the sliding groove and protrudes to the right.

[0012] The right vehicle body platform includes a right vehicle body platform body, and a drive motor mounting bracket is fixedly installed on the rear left side of the right vehicle body platform.

[0013] The aforementioned misalignment unfolding mechanism includes a sliding sleeve, and a rotating shaft sleeve is integrally provided at the right position of the longitudinal rear end of the sliding sleeve; one end of a translational hydraulic cylinder is also hinged to the sliding sleeve; the rotating shaft sleeve is driven to rotate by a rotary drive motor.

[0014] The sliding sleeve is mounted on the slide rail, and the other end of the translation cylinder is hinged to the cylinder mounting boss. The left vehicle platform is driven by the translation cylinder to slide and misalign longitudinally relative to the sliding sleeve.

[0015] The drive motor mounting bracket contains a rotary drive motor. The left vehicle platform is driven by the rotary drive motor to rotate and extend longitudinally relative to the rear end of the right vehicle platform until the longitudinal end of the left vehicle platform is connected to the longitudinal end of the right vehicle platform.

[0016] Furthermore, a first connector is longitudinally arranged on the right side wall of the cylinder mounting boss, a second connector is longitudinally arranged on the right side wall of the sliding sleeve, and a third connector is transversely arranged at the rear end of the left vehicle platform body.

[0017] The right vehicle platform body has a transverse merging connection groove on its left side wall. The length of the transverse merging connection groove is arranged along the longitudinal direction and is longitudinally continuous. When the left vehicle platform and the right vehicle platform are in a transverse merging state, the first connector and the second connector can be embedded in the transverse merging connection groove to realize the transverse merging connection between the left vehicle platform and the right vehicle platform.

[0018] The rear side wall of the right vehicle platform is provided with a longitudinal unfolding connection groove, the length of which is arranged horizontally and runs through the entire length of the groove. When the left and right vehicle platforms are in the longitudinal unfolded state, the third connector can be embedded in the longitudinal unfolding connection groove to realize the longitudinal unfolding connection between the left and right vehicle platforms.

[0019] The present invention also protects a method of using an advanced exploration integral drilling rig applicable to roadway excavation faces as described above, the method of use comprising the following steps.

[0020] Step 1: When drilling the advanced exploration hole on the left front, the left and right car bodies of the advanced exploration integral drilling rig slide down under the drive of the misalignment unfolding mechanism to form a longitudinal misalignment structure.

[0021] Step 2: When the advanced exploration integral drilling rig makes way for the tunneling machine, the left and right car bodies of the advanced exploration integral drilling rig rotate under the drive of the staggered deployment mechanism to form a longitudinally deployed structure.

[0022] Compared with the prior art, the present invention has the following technical effects.

[0023] (I) In this invention, the drilling rig body is set as a left body and a right body. Under normal working conditions, the two bodies are integrated into one unit, and its walking and drilling state is similar to that of a conventional crawler drilling rig. When it is necessary to construct a small-angle advance exploratory hole in front of the left side of the tunneling face, the left body can slide backward a certain distance to highlight the position of the drilling device in the right body. When it is necessary to make way for the tunnel boring machine, the advance drilling rig can move to the right side of the tunnel. After the upper and lower stable columns in the right body are pressed against the top and bottom plates of the tunnel, the left body unfolds longitudinally and moves close to the right side of the tunnel. This reduces the width of the advance drilling rig body, which is conducive to the smooth passage of the tunnel boring machine.

[0024] (II) After the left and right vehicle bodies of the present invention are misaligned and moved, the straight-line walking performance and overall stability of the drilling rig are not affected.

[0025] (III) During and after the longitudinal unfolding of the left side of the vehicle body of the present invention, the drilling rig column is tightly pressed against the roof and floor of the roadway, which provides good stability and safety.

[0026] (IV) During the drilling operation of the present invention, when the tunnel excavation face does not have the conditions to have the upper and lower stable columns to hold the roof plate tightly due to reasons such as roof fall, the left side of the vehicle body can be rotated to the left to form a T-shaped structure, thereby increasing the overall stability of the advanced exploration integral drilling rig.

[0049] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0050] Example 1:

The left vehicle body 1 includes a left vehicle body platform 101, and the right vehicle body 2 includes a right vehicle body platform 201.

[0052] like Figures 4 to 6 As shown, one end of the offset deployment mechanism 3 is rotatably mounted on the rear end of the right vehicle platform 201, and the other end of the offset deployment mechanism 3 is fitted onto the left vehicle platform 101; as Figures 4 to 5 As shown, the left vehicle platform 101, driven by the offset deployment mechanism 3, can slide longitudinally relative to the right vehicle platform 201, achieving a sliding longitudinal offset; as Figure 6 As shown, the left vehicle platform 101 can rotate and longitudinally unfold around the rear end of the right vehicle platform 201 under the drive of the offset unfolding mechanism 3.

[0053] As one specific solution in this embodiment, such as Figure 7 and Figure 8 As shown, the left vehicle platform 101 includes a left vehicle platform body 10101. The left vehicle platform body 10101 has a horizontally through-groove 10102 inside. The length of the groove 10102 is arranged along the longitudinal direction.

[0056] like Figure 8 As shown, the sliding sleeve 301 is mounted on the slide rail 10103, and the other end of the translation cylinder 303 is hinged to the cylinder mounting boss 10104. The left vehicle platform 101 is driven by the translation cylinder 303 to slide and misalign longitudinally relative to the sliding sleeve 301.

[0057] like Figure 9As shown, a rotary drive motor 304 is installed inside the drive motor mounting sleeve 20102. The left vehicle platform 101 is driven by the rotary drive motor 304 to rotate and longitudinally unfold relative to the rear end of the right vehicle platform 201 until the longitudinal end of the left vehicle platform 101 is connected to the longitudinal end of the right vehicle platform 201.

[0058] As a further solution in this embodiment, such as Figure 8 As shown, a first connector 10105 is arranged longitudinally on the right side wall of the cylinder mounting boss 10104, a second connector 10106 is arranged longitudinally on the right side wall of the sliding sleeve 301, and a third connector 10107 is arranged laterally at the rear end of the left vehicle platform body 10101.

[0059] like Figure 9 As shown, a transverse merging connection groove 20103 is provided on the left side wall of the right vehicle body platform 20101. The transverse merging connection groove 20103 is arranged longitudinally and runs through the longitudinal direction. When the left vehicle body platform 101 and the right vehicle body platform 201 are in a transversely merged state, the first connector 10105 and the second connector 10106 can be embedded in the transverse merging connection groove 20103 to realize the transverse merging connection between the left vehicle body platform 101 and the right vehicle body platform 201.

[0060] like Figure 9 As shown, a longitudinal unfolding connection groove 20104 is provided on the rear side wall of the right vehicle platform body 20101. The longitudinal unfolding connection groove 20104 is arranged in the transverse direction and runs through the entire length of the groove. When the left vehicle platform 101 and the right vehicle platform 201 are in the longitudinal unfolded state, the third connector 10107 can be embedded in the longitudinal unfolding connection groove 20104 to realize the longitudinal unfolding connection between the left vehicle platform 101 and the right vehicle platform 201.

[0061] As a further solution in this embodiment, such as Figure 8 As shown, the first connector 10105 has a vertically penetrating first pin hole 10108; the second connector 10106 has a vertically penetrating third pin hole 10109; and the third connector 10107 has a vertically penetrating third pin hole 10110.

[0062] like Figure 9 As shown, a fourth pin hole 20105 corresponding to the first pin hole 10108 is provided on the transverse merging connecting groove 20103, a fifth pin hole 20106 corresponding to the second pin hole 10109 is provided on the transverse merging connecting groove 20103, and a sixth pin hole 20107 corresponding to the third pin hole 10110 is provided on the longitudinal unfolding connecting groove 20104.

[0063] like Figure 9 As shown, the first pin hole 10108 and the fourth pin hole 20105 are connected by the first pin 10, and the second pin hole 10109 and the fifth pin hole 20106 are connected by the second pin 11. The first pin 10 and the second pin 11 are used to achieve lateral merging and locking; the third pin hole 10110 and the sixth pin hole 20107 are connected by the third pin 12. The third pin 12 is used to achieve longitudinal unfolding and locking.

[0064] As a further solution in this embodiment, such as Figure 10 As shown, the sliding sleeve 301 includes a sliding sleeve body 30101, which is a hollow structure that runs longitudinally through the body. An opening 30102 is provided at the bottom of the sliding sleeve body 30101, and bottom limiting plates 30103 are located on both sides of the opening 30102. The lateral width of the opening 30102 is smaller than the lateral width of the sliding sleeve 301, and the lateral width of the opening 30102 is larger than the total lateral width of the left upright plate 103 and the left track 104 in the left vehicle body 1, so that the left upright plate 103 and the left track 104 in the left vehicle body 1 do not interfere with the bottom limiting plates 30103 when passing through the opening 30102. The sliding sleeve body 30101 is fitted onto the slide rail 10103, and the bottom limiting plates 30103 are located at the bottom of the slide rail 10103 for vertical limiting.

[0065] In this embodiment, a sliding sleeve mounting port can be provided on the slide rail 10103 as needed, so that the sliding sleeve 301 can be fitted onto the slide rail 10103. A detachable slide rail is installed on the sliding sleeve mounting port, and the detachable slide rail can complete the sliding sleeve mounting port, so that the slide rail 10103 is a complete slide rail.

[0066] As one specific solution in this embodiment, such as Figure 9 As shown, a drilling device 4 is installed on the right vehicle body platform 201, such as... Figure 8 As shown, the left vehicle platform 101 is equipped with a motor pump unit 5, an electrical cabinet 6, an oil tank 7, and a control panel 8.

[0067] In this embodiment, the drilling device 4 adopts a commonly known drilling device 4 in the art, mainly including a main platform, slewing bearing, machine body, power head, and clamping device. The function of the drilling device 4 is to drive the drill rod, drill bit, and other drilling tools to perform rotation, feeding, and other actions to complete the drilling construction. All components and equipment in the drilling device 4 adopt commonly known components and equipment in the art, and the specific connection and installation methods of each component adopt commonly known connection and installation methods in the art. The drilling device 4 is also equipped with an angle adjustment mechanism as needed, and the angle adjustment mechanism can be any angle adjustment mechanism known in the art.

[0068] In this embodiment, the motor pump unit 5, electrical cabinet 6, oil tank 7 and control panel 8 are all commonly used motor pump units 5, electrical cabinet 6, oil tank 7 and control panel 8 known in the art.

[0069] As one specific solution in this embodiment, such as Figure 8 As shown, a lower stabilizing component 102 is installed at the longitudinal front bottom of the left vehicle platform 101, a left vertical plate 103 is installed at the lower part of the left vehicle platform 101, and a left track 104 is installed on the left side of the left vertical plate 103.

[0070] As one specific solution in this embodiment, such as Figure 9 As shown, two stabilizing column mounting ports 20108 are vertically opened at the front and rear longitudinal positions of the right vehicle body platform 201. A vertical stabilizing column 202 is installed through each of the four stabilizing column mounting ports 20108. A right vertical plate 203 is installed at the lower part of the right vehicle body platform 201, and a right track 204 is installed on the right side of the right vertical plate 203.

[0071] In this embodiment, as Figure 6 As shown, the lower stabilizing component 102 adopts a commonly used lower stabilizing component known in the art. The lower stabilizing component 102 consists of a hydraulic cylinder and a universal wheel. The hydraulic cylinder can extend downwards, and the universal wheel is installed at the end of the hydraulic cylinder. When the whole machine is stable, the two sides of the vehicle body slide and misalign or extend longitudinally, the lower stabilizing component 102 can extend to the ground to play an auxiliary support role, so as to avoid the jamming phenomenon at the pivot point due to the unbalanced force when the left side of the vehicle body rotates.

[0072] In this embodiment, as Figure 9 As shown, the four sturdy column mounting ports 20108 can prevent the upper and lower sturdy columns 202 from being directly installed on the side wall of the vehicle platform, thus avoiding an increase in the width of the right side of the vehicle body 2.

[0073] In this embodiment, as Figure 9 As shown, the upper and lower stabilizing columns 202 consist of two hydraulic cylinders. The lower cylinder is used to tighten the tunnel floor and lift the tracks off the ground, while the upper cylinder is used to tighten the tunnel roof. Normally, the tracks do not contact the ground during drilling, reducing damage to the tracks from the alternating forces generated during drilling. The upper cylinder extends to tighten the tunnel roof, stabilizing the drilling rig between the tunnel floor and roof. Both the upper and lower cylinders have top-receiving plates at their ends to increase the contact area with the tunnel roof.

[0074] In this embodiment, as Figure 8As shown, two mounting plates with bolt holes are provided on the same side of the left track 104, which are connected to the left upright plate 103 by bolts; a boss is provided at the lower end of the left upright plate 103. When connected to the left track 104, the boss is inserted between the two mounting plates of the left track 103, which reduces the stress on the cross section of the bolt and makes the connection more stable and reliable.

[0075] Example 2: This embodiment provides a method for using the advanced exploration integral drilling rig for roadway excavation working faces as described in Embodiment 1. The method includes the following steps.

[0076] Step 1: When drilling the advance exploration borehole 18 on the left front, the method of using the advance exploration integral drilling rig 9 is as follows.

[0077] Step 101: The advanced exploration integral drilling rig 9 travels to the position where the left sidewall 15 and the tunneling face 14 are at an angle. The drilling azimuth angle of the drilling device 4 is made the same as the design drilling azimuth angle by adjusting the left track 104 and the right track 204.

[0078] Step 102: Control the lower stabilizer in the upper and lower stabilizing columns 202 to extend, and the hydraulic cylinder in the lower stabilizing component 102 to extend, pushing the left track 104 and right track 204 away from the roadway floor. Control the upper stabilizer in the upper and lower stabilizing columns 202 to extend and press against the roadway roof.

[0079] Step 103: Pull out the first pin 10 and control the cylinder rod of the translation cylinder 303 to retract. At this time, the left vehicle platform 101 and its connecting parts slide backward along the limited direction inside the sliding sleeve 301, and the left vehicle body 1 and the right vehicle body 2 form a longitudinally misaligned structure.

[0080] Step 104: First, retract the upper stabilizer in the upper and lower stabilizing columns 202, then retract the lower stabilizer in the upper and lower stabilizing columns 202 and the hydraulic cylinder in the lower stabilizing assembly 102 at the same time, so that the left track 104 and the right track 204 come into contact with the tunnel floor.

[0081] Step 105: Control the left track 104 and right track 204 to move forward to the side of the tunnel and begin drilling.

[0082] Step 2, when the advanced exploration integrated drilling rig 9 makes way for the tunneling machine 13, the operation method of the advanced exploration integrated drilling rig 9 is as follows.

[0083] Step 201: The advanced exploration integral drilling rig 9 travels to the position of the right sidewall 16, while keeping the right side of the vehicle body 2 as close as possible to the right sidewall 16, and keeping the left track 104 and right track 204 traveling in the same direction as the extension direction of the tunnel.

[0084] Step 202: Control the lower stabilizer in the upper and lower stabilizing columns 202 to extend, and the hydraulic cylinder in the lower stabilizing component 102 to extend, pushing the left track 104 and right track 204 away from the roadway floor. Control the upper stabilizer in the upper and lower stabilizing columns 202 to extend and press against the roadway roof.

[0085] Step 203: Pull out the first pin 10 and the second pin 11, control the rotary drive motor 304 in the right vehicle body 2 to drive the left vehicle body 1 to rotate, the left vehicle body platform 101 and the right vehicle body platform 201 form a longitudinal unfolding structure until the third connector 10107 of the left vehicle body platform 101 is embedded in the longitudinal unfolding connecting groove 20104 of the right vehicle body platform 201, and then insert the third pin 12 into the third pin hole 10110 and the corresponding sixth pin hole 20107; the width of the advanced exploration integral drilling rig 9 in the longitudinal unfolding state is 1 / 2 of the width in the initial transverse merging state, achieving the avoidance effect.

[0086] In this embodiment, as Figure 11 As shown, when the roadway does not meet the conditions for tightening the roof during drilling due to reasons such as roof collapse, the left side of the vehicle body 1 can also be rotated to the position shown. Figure 11 The location shown increases the contact area with the tunnel floor, enhancing the overall stability of the machine during drilling.

[0087] In this embodiment, as Figure 12 As shown, when conventional advanced exploration integral drilling rigs are used for large-angle drilling near the left side of the tunnel, due to the rig's width, a significant distance must be maintained between the rig and the working face to ensure proper drilling according to the design. This large distance can easily lead to a series of problems, such as difficulty in drilling, excessive ineffective drilling, and exposed moving parts causing safety hazards. For example... Figure 13 As shown, the advanced exploration integral drilling rig of the present invention has a sliding function of the left side of the vehicle body. After the vehicle body slides, the right side of the vehicle body protrudes, making it easier to get close to the tunneling face to construct large-angle boreholes near the left side of the tunnel.
