Description

Technical Field

[0001] The present application relates to the field of drilling equipment, and in particular to a rock drilling equipment and a construction process thereof that is easy to construct. Background Art

[0002] Currently, the most common rock drilling equipment is mainly down-the-hole drills and rock drills. Compared with rock drills, down-the-hole drills are more versatile due to their advantages such as deep drilling, large drilling diameter, high drilling efficiency, and wide adaptability. They are currently the most commonly used large-scale rock drilling equipment.

[0003] Most of the existing down-the-hole drills are simple crawler-type structures, which generally include a frame, a drill rig body, a drill frame and drilling tools. The frame is equipped with walking tracks, a hydraulic system, an air supply system, a cylinder power system and a drill arm (hereinafter referred to as the "hydraulic system, air supply system, and cylinder power system"). The drill arm is used to connect the frame and the drill frame. The hydraulic system, air supply system and drill arm cooperate to adjust the front and rear direction of the drill frame. The drill rig body includes a cab and a central integrated control system for down-the-hole drills located in the cab. The drill rig body controls the hydraulic power system to drive the drill rig body and the drill arm to drive the drill frame to rotate horizontally around the frame. The drilling tool is installed on the drill frame. The drilling tool includes a main drill rod, a drill bit and an impactor. The impactor is equipped with an impact hammer. After the drill rig body and the frame are moved to the working position by the walking tracks, the operator positions the drill frame by fixing it to the ground, and then uses the main drill rod to drive the drill bit and the impactor to align with the position to be drilled for impact drilling.

[0004] With regard to the above-mentioned related technologies, in order to maintain the relative stability of components such as the drill bit and the impactor relative to the position to be drilled during the drilling process and to prevent the drill bit and the impactor from shifting significantly during the drilling process, the drill frame and the drill arm of the down-the-hole drill in the related technology are generally connected by a hinge, and the drill frame and the drill arm are fixed with linear drive parts such as hydraulic cylinders / pneumatic cylinders. When the drilling rig moves to the working position and the position of the drilling rig body, frame and walking tracks remains unchanged, the drill arm can mostly only swing back and forth and up and down. Correspondingly, the drill frame can only swing back and forth and up and down relative to the drilling rig body and frame along the back and forth swing of the drill arm; when the operator needs to adjust the drilling position angle of the drill bit and the impactor, the operator needs to control the frame, the drilling rig body and the drill arm to rotate, which is relatively difficult to operate and control, and can easily affect the construction efficiency. Summary of the Invention

[0005] In order to improve the problem in the related art that the drilling position angle of the down-the-hole drill is difficult to adjust and control after the drill rig moves to the working position, the present application provides a rock drilling equipment and a construction process that is easy to construct.

[0006] This application provides a rock drilling device that is easy to construct and adopts the following technical solution:

[0007] The jack-up plate is connected to the support frame by a hydraulic cylinder to move the hydraulic cylinder to move upwards to drive the jack-up plate, and the hydraulic cylinder is connected to the support frame by a hydraulic cylinder to move upwards to drive the jack-up plate to move upwards to drive the jack-up plate to move upwards to drive the jack-up plate to move upwards to drive the jack-up plate to move

[0008] By adopting the above technical solution, the rock drilling equipment in the present application can first be preliminarily moved to a working position adjacent to the drilling hole by means of the walking crawler and the hydraulic power system, so that the distance between the frame and the drill rig body and the position to be drilled is adapted to the actual length and swing range of the drill arm; then the operator can use the down-the-hole drill central integrated control system in the cab of the drill rig body to control the drill arm to swing back and forth, drive the drill frame and the drill tool to move above the position to be drilled, and correspondingly use the rotation locking mechanism to drive the drill frame to rotate relative to the mounting base (i.e., the drill arm) to adjust the angle of the pre-drilling position of the rock drilling equipment. The pre-drilling position is aligned with the position to be drilled, and the operator can more conveniently adjust the position and angle of the drill rig and drilling tools; and the rock drilling equipment in this application has a larger rotation radius than the traditional down-the-hole drill, and the angle adjustment range between the drill rig and the drill arm is also smaller than that of the drill arm, which is more convenient to control; when there are multiple adjacent positions to be drilled, the operator does not need to move the drill rig body and the work station where the frame is located, nor does he need to adjust the rotation range of the swing arm. Multiple holes can be drilled at one work station without moving each hole, thereby effectively reducing the drilling gap, which is conducive to reducing the control difficulty and improving construction efficiency.

[0009] Optionally, the drilling tool includes a main drill rod, a drill bit and an impactor, the main drill rod is parallel to the drill frame and is installed on the upper side of the drill frame, and a universal joint is protruded and fixedly connected in the middle of the lower side of the drill frame; a mounting shaft is integrally protruded in the middle of a side of the mounting seat away from the drill arm, and the rotation locking mechanism includes a meshing active worm gear and a worm and a driving component for driving the worm gear to rotate, the active worm gear is coaxially sleeved and rotatably connected to the mounting shaft in a non-slip manner, the worm gear is rotatably mounted on the fixed seat, and the universal joint is coaxially sleeved and fixedly mounted on the active worm gear.

[0010] By adopting the above technical solution, the drill rig and the drill tool are fixed to the active worm gear through a universal joint, and are rotatably mounted on the mounting shaft of the mounting seat at the end of the drill arm through the active worm gear in a non-slip manner; the driving component is used to drive the worm to rotate, which can drive the active worm gear to stably transmit around the mounting shaft, thereby driving the drill rig and the drill tool to rotate relative to the drill arm, and the angle adjustment of the drill rig and the drill tool on the drill arm can be achieved more smoothly and conveniently; and because the worm gear transmission has a self-locking property and the axial force of the worm is also large, when the drill rig and the drill tool rotate to the point where the pre-drilling position coincides with the position to be drilled, the worm gear stops rotating, the active worm gear stops rotating, and the drill rig and the drill tool also stop rotating accordingly, which is conducive to the stable drilling of the drill rig and the drill tool, reduces the deviation between the actual drilling position of the drill rig and the drill tool and the position to be drilled during the drilling process, and provides effective safety protection during the drilling operation.

[0011] Optionally, a driven worm gear is coaxially slidably connected to the inner side of the driving worm gear, and a linear drive member is fixedly mounted on the mounting seat for driving the driven worm gear to slide back and forth on the driving worm gear in a direction parallel to its axis, and the driven worm gear is movably engaged with the worm.

[0012] By adopting the above technical solution, the active worm gear and the worm play a major driving role in controlling the rotation of the drill rig on the drill arm; when the operator uses the worm and the active worm gear to drive the drill rig to rotate on the drill arm, the linear drive member is used to drive the driven worm gear to linearly approach the worm and mesh the driven worm gear with the worm, so that the driven worm gear can cooperate with the active worm gear to achieve a double multi-tooth meshing transmission with the worm, making the transmission between the worm and the worm gear smoother and effectively enhancing the carrying capacity of the active worm gear, thereby enhancing the stability between the drill rig when it rotates on the drill arm and when the drill rig is locked relative to the drill arm, thereby achieving stability of the drill rig on the drill arm, convenient angle adjustment and stable drilling.

[0013] Optionally, the driving worm gear and the driven worm gear both include a ring body and a plurality of cylinders arranged around one side of the ring body along the circumferential direction of the ring body, the angles formed by two adjacent cylinders on the driving worm gear and the driven worm gear and the axes of the driving worm gear and the driven worm gear are consistent, and the cylinders are movably inserted and engaged with the thread groove of the worm.

[0014] By adopting the above technical solution, the driving worm gear between the multiple columns and the ring body is a special-shaped worm gear that is different from the traditional worm gear. The operator can customize the driving worm gear according to the minimum spacing between two adjacent holes in actual construction specifications / construction experience, so that the angle formed by the two adjacent columns on the driving worm gear / driven worm gear and the axis of the driving worm gear / driven worm gear can more accurately and effectively adapt to the minimum spacing between two adjacent holes when the worm rotates a certain number of turns or a certain angle. This makes it easier for the operator to control the rotation of the drill rack by controlling the number of turns / rotation angle of the worm, so that the pre-drilled hole position of the drill tool can be more accurately and conveniently coincided with the actual hole position to be drilled.

[0015] Optionally, a rotating ring is coaxially connected to the inner side of the driven worm gear in a non-slip manner, and both ends of the linear drive member are respectively perpendicularly and fixedly connected to the mounting seat and the rotating ring, and the rotating ring is axially slidably connected to the mounting shaft along the mounting shaft.

[0016] By adopting the above technical solution, the existence of the rotating ring enables the driven worm gear to always rotate circumferentially around the axis of the mounting shaft. By using the linear drive member to pull the rotating ring toward the mounting seat, the driven worm gear can be pulled close to the worm and meshed with the worm more conveniently and stably, thereby facilitating the realization and control of the double multi-tooth meshing transmission process of the driven worm gear and the driving worm gear to the worm.

[0017] Optionally, a plurality of groups of bolts are evenly provided on a side of the universal joint close to the drill frame, and the universal joint is fixedly mounted on the driving worm gear by the plurality of groups of bolts.

[0018] By adopting the above technical solution, the operator can achieve detachable fixation of the universal joint and the active worm gear by screwing and removing multiple sets of bolts, thereby realizing detachable replacement of the drill rig and drill tools on the drill arm, which is convenient for the operator to quickly replace the drill rig and drill tools on the rock drilling equipment according to the actual size of the hole to be drilled, thereby improving the utilization efficiency of the rock drilling equipment and ensuring the connection stability of the drill rig and drill arm.

[0019] Optionally, there are two groups of worms and driving components, which are respectively located on both sides of the installation shaft, and the two groups of worms are perpendicular to each other, the distances between the two groups of worms and the installation shaft are consistent, and the two groups of worms rotate in opposite directions.

[0020] By adopting the above technical solution, two sets of worms and driving components are used to simultaneously engage and drive the active worm gear. The structure of the two sets of worms is more compact. Compared with the transmission of a single set of worms, the two sets of worms can obtain a better engagement effect than a single set of worms. The load-bearing capacity between the active worm gear and the worm is also higher. The angle adjustment of the drill frame on the drill arm and the drilling of the drill tool on the drill frame are correspondingly more stable.

[0021] Optionally, a positioning light emitting linear light toward one side is fixedly installed on the drill rig, the light emission direction of the positioning light is parallel to the main drill rod, and the light emitting end of the positioning light faces downward, and the opening and closing of the positioning light is controlled by the down-the-hole drill central integrated control system in the drilling rig body.

[0022] By adopting the above technical solution, when the drill rig and the drilling rig body move to the work station and no longer move, the operator can use the down-the-hole drill central integrated control system in the cab to turn on the positioning light, and use the positioning light to emit straight light to form an image on the ground and preliminarily locate the pre-drilling position of the drill tool, thereby improving the accuracy of the overlap between the pre-drilling position and the position to be drilled, and effectively improving the positioning efficiency of the pre-drilling position of the drill tool.

[0023] Optionally, a fixing component for connecting the drill rack to the ground is fixedly installed at the lower end of the drill rack.

[0024] By adopting the above technical solution, after the operator moves the drill rig and drilling tools to the predetermined working position, the operator can use the fixing assembly to plug and fix the drill rig to the ground, so that the drill rig and even the rock drilling equipment as a whole are more stable on the ground during the drilling process, thereby ensuring the drilling quality of the rock drilling equipment.

[0025] The present application also provides a rock drilling construction process, comprising the following steps:

[0026] S1: Using the crawler tracks to initially move the rock drilling equipment to the working position;

[0027] S2: The central integrated control system of the down-the-hole drill drives the hydraulic power system to drive the cab and the drill boom to rotate horizontally, so that the position to be drilled is within the forward and backward swing range of the drill boom to the left / right 0.2-0.5m. The drill boom is then swung forward and backward to its working position and the drill boom is kept stationary relative to the frame, so that the projection of the drill frame and drilling tools on the ground covers the position to be drilled;

[0028] S3: Use the positioning light to locate the pre-drilling position of the drill bit and the hammer. When the pre-drilling position coincides with the position to be drilled, use the fixing assembly to fix the drill frame and the ground, and control the main drill rod to drive the drill bit and the hammer to drill. When there is an offset between the pre-drilling position and the drilling position, use the driving component to drive the drill frame and the main drill rod to rotate relative to the drill arm, fine-tune the position of the main drill rod, so that the pre-drilling position coincides with the position to be drilled, and control the main drill rod to drive the drill bit and the hammer to drill.

[0029] S4: After the drilling is completed, the drill frame is unlocked from the ground, the drill arm is retracted, and the rock drilling equipment is initially moved to the next working position using the walking crawler, and the above steps are repeated.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By utilizing a worm gear structure to rotatably mount the drill rig on the drill boom, and using a rotation locking mechanism to drive and control the rotation of the drill rig on the drill boom, the position and angle of the drill rig and drilling tool can be easily adjusted after the rock drilling equipment is moved to the working position. This allows the pre-drilled hole position to be easily aligned with the hole to be drilled. Multiple holes can be drilled at one workstation without having to move the machine one hole at a time. This effectively reduces drilling clearances, reduces control difficulty, and effectively improves construction efficiency.

[0032] 2. By utilizing the driven worm gear and the active worm gear in conjunction, the transmission between the worm and the worm gear becomes smoother, and the load-bearing capacity of the active worm gear is effectively enhanced, thereby enhancing the stability between the drill rig when rotating on the drill boom and when the drill rig is locked relative to the drill boom, achieving stable positioning of the drill rig on the drill boom, convenient angle adjustment, and stable drilling.

[0033] 3. By using multiple sets of bolts to detachably fix the universal joint to the driving worm gear and allowing the driving worm gear to rotate on the fixed shaft without slipping, the drill rig and drilling tools can be easily disassembled, assembled, and replaced, while ensuring the connection stability between the drill rig and the drill boom, thereby improving the adaptability of the rock drilling equipment to the required hole diameters for drilling in different geological conditions.

[0040] The following is combined with Figure 1-5 This application is described in further detail.

[0041] The embodiment of the present application discloses a rock drilling device that is easy to construct.

[0042] Reference Figure 1 A rock drilling equipment convenient for construction includes a frame 1, a drilling rig body 2, a drill frame 3 and a drilling tool 4. A walking crawler 11 for moving the rock drilling equipment on the ground is installed under the frame 1, and a base 12 for installing the drilling rig body 2 is installed horizontally and rotatably above the frame 1. A hydraulic power system (including but not limited to a hydraulic system, an air supply system, a cylinder power system, etc.) and a drill arm 13 for providing power for the operation of the equipment are also installed on the frame 1; the drilling rig body 2 includes a cab and a down-the-hole drill central integrated control system provided in the cab. The drilling rig body 2 controls the hydraulic power system to drive the drilling rig body 2 and the drill arm 13 to drive the drill frame 3 to rotate horizontally around the frame 1; the drilling tool 4 is installed on the drill frame 3, and the drill arm 13 is used to connect the frame 1 and the drill frame 3.

[0043] Specifically, the drill arm 13 in the present application is a three-section swing arm, which includes three interconnected swing arms. The three swing arms are connected in pairs, and the two connected swing arms are hinged at their connection points. The hinge axes of any two swing arms are parallel to each other and perpendicular to the swing arms. The operator can use the hydraulic power system to drive the adjacent swing arms at both ends to rotate relative to each other, thereby driving the drill arm 13 to swing back and forth relative to the drilling rig body 2; the hydraulic power system can be a down-the-hole drill hydraulic power system or an excavator platform hydraulic power system.

[0044] In order to improve the problem in the related art that the drilling position angle of the down-the-hole drill is difficult to adjust and control after the drill rig moves to the working position, the lower end of the drill arm 13 is hinged to the base 12, and the upper end is hinged to a mounting seat 14 for mounting the drill rig 3 and the drilling tool 4. The drill rig 3 is rotatably connected to the side of the mounting seat 14 away from the drill arm 13, and a rotation locking mechanism 5 is provided between the mounting seat 14 and the drill rig 3 for driving the drill rig 3 to rotate relative to the mounting seat 14 and locking the rotation of the drill rig 3.

[0045] Specifically, refer to Figure 1 and Figure 2 The hinge axes at the upper and lower ends of the drill arm 13 and the hinge axes between the swing arms in the drill arm 13 are parallel to each other, and the above-mentioned hinge axes are perpendicular to the drill arm 13. The operator can use the down-the-hole drill central integrated control system in the cab to control the hydraulic power system to drive the drill arm 13 relative to the base 12 and the mounting base 14 relative to the drill arm 13 to rotate around the corresponding hinge axis.

[0046] The mounting base 14 includes a disc body 141 and a connecting arm 142 that are integrally connected. The disc body 141 is disc-shaped. The connecting arm 142 is located in the middle of one side of the disc body 141, and the end of the connecting arm 142 is perpendicular to and connected to the disc body 141. The end of the connecting arm 142 away from the disc body 141 is hinged to the upper end of the drill arm 13, and the connecting arm 142 is powered by a hydraulic power system and is suitable for stably rotating around the hinge axis between the connecting arm 142 and the drill arm 13 under the control of the down-the-hole drill central integrated control system.

[0047] Reference Figure 2 and Figure 3 The drill frame 3 is rotatably mounted on the side of the disk body 141 away from the connecting arm 142, and the rotation axis of the drill frame 3 on the disk body 141 is coaxial with the disk body 141. The drilling tool 4 includes a main drill rod 41, a drill bit and a hammer. The main drill rod 41 is parallel to the drill frame 3 and is mounted on the upper side of the drill frame 3. The middle part of the lower side of the drill frame 3 is protruding and fixedly connected with a universal joint 31 that is adapted to the disk body 141 in the mounting seat 14; the universal joint 31 is also disc-shaped, and the diameter of the universal joint 31 is consistent with that of the disk body 141. The universal joint 31 is suitable for docking with the disk body 141, and a circular opening is opened on the side close to the universal joint 31 and the disk body 141. When the universal joint 31 and the disk body 141 are in contact with each other, the empty grooves between the universal joint 31 and the disk body 141 are connected and together constitute a receiving groove 143 for installing the rotation locking mechanism 5.

[0048] Specifically, the mounting seat 14 is provided with a mounting shaft 15 protruding from the middle of the side away from the drill arm 13. The mounting shaft 15 is located in the empty groove of the disc body 141 and the side of the mounting shaft 15 away from the disc body 141 protrudes to the outside of the disc body 141; Figure 2 、 Figure 3and Figure 4 The rotation locking mechanism 5 includes a meshing driving worm wheel 51 and a worm 52 and a driving component 53 for driving the worm 52 to rotate.

[0049] An inwardly recessed, annular anti-slip groove 151 is coaxially provided on the outer peripheral wall of the mounting shaft 15 on the side away from the disc body 141. An annular portion that is compatible with the anti-slip groove 151 is integrally protruded on the inner side of the driving worm gear 51, and the driving worm gear 51 is coaxially sleeved and rotatably connected to the mounting shaft 15 through the anti-slip groove 151 and the annular portion; the worm 52 is rotatably mounted on the universal joint 31, and the universal joint 31 is coaxially sleeved and fixedly mounted on the driving worm gear 51.

[0050] The driving component 53 is used to drive the worm 52 to rotate, which can drive the active worm gear 51 to stably transmit the power around the mounting shaft 15, thereby driving the drill rig 3 and the drill tool 4 to rotate relative to the drill arm 13. When the working positions of the frame 1 and the drilling rig body 2 remain unchanged, the angles of the drill rig 3 and the drill tool 4 on the drill arm 13 are adjusted so that the pre-drilling position of the drill rig 3 and the drill tool 4 coincide with the position to be drilled. At the same time, when the operator uses the worm 52 to drive the active worm gear 51 to rotate 360° around the mounting shaft 15, the active worm gear 51 can correspondingly drive the drill rig 3 and the drill tool 4 to rotate 360° around the drill arm 13 in the vertical plane. Moreover, since the worm gear 52 has a self-locking transmission and the axial force of the worm 52 is also relatively large, when the drill rig 3 and the drill tool 4 rotate to the point where the pre-drilling position coincides with the position to be drilled, the worm 52 stops rotating, the active worm gear 51 stops rotating, and the drill rig 3 and the drill tool 4 also stop rotating accordingly.

[0051] In order to facilitate the stable rotation of the universal joint 31 on the disk 141 and effectively reduce the operator's control over the number of rotations and the rotation angle of the worm 52, in the embodiment of the present application, the driving component 53 is a hydraulic motor, which is part of the hydraulic power system and is controlled by the down-the-hole drill central integrated control system in the cab.

[0052] The hydraulic motor has a stronger driving force than the drive motor, and its application environment is relatively more resilient. It can better adapt to the dusty and watery environment during the construction of water conservancy projects. Its start and stop control is also faster, and it can conveniently and automatically control overload accidents, making it easy to control; the end of the worm 52 is coaxially fixedly connected to the output shaft of the hydraulic motor, controlling the start and stop of the hydraulic motor and controlling the operation of the hydraulic motor. It can drive the worm 52 to drive the active worm gear 51 to start, stop or operate more conveniently, stably, powerfully and quickly, thereby realizing convenient control of the angle adjustment between the drill rig 3 and the drill arm 13.

[0053] In addition, refer to Figure 1 and Figure 2In the embodiment of the present application, the driving and operation of the drilling tool 4 is mainly achieved by installing an external air compressor on the drill rig 3 and relying on the hydraulic power system of the excavator platform. The drill arm 13 is externally connected to a hydraulic pipe 131 and an air duct 132. The hydraulic pipe 131 and the air duct 132 are both hoses. The inlet end of the hydraulic pipe 131 and the air inlet of the air duct 132 are both connected to the drilling rig body 2, and the hydraulic channel of the hydraulic motor is threadedly assembled to the hydraulic pipe 131 through a detachable pipe joint. The air inlet end of the external air compressor is connected to the air outlet of the air duct 132; wherein, the forward propulsion of the main drill rod 41 is powered by the hydraulic power system and the hydraulic pipe 131, and the drill bit and the hammer perform rock drilling and crushing at the front end of the main drill rod 41. The external air compressor takes in air through the air duct 132 and discharges air at its outlet to blow away the drilled residue during the rock drilling and crushing process of the drill bit and the hammer.

[0054] Furthermore, in order to enhance the strength and stability of the support and bearing of the rotation locking structure 5 between the drill arm 13 and the drill frame 3, refer to Figure 4 and Figure 5 The driving worm gear 51 is also coaxially slidably connected to the inner side of the driven worm gear 54. In the embodiment of the present application, the driving worm gear 51 and the driven worm gear 54 both include a ring body 511 and a plurality of columns 512 arranged around one side of the ring body 511 along the circumferential direction of the ring body 511. The main body is cylindrical. The angles formed by the two adjacent columns 512 on the driving worm gear 51 and the driven worm gear 54 and the axes of the driving worm gear 51 and the driven worm gear 54 are consistent, and the columns 512 of the driving worm gear 51 and the driven worm gear 54 are movably plugged into and engaged with the thread groove of the worm 52.

[0055] At the same time, the inner side of the driving worm gear 51 is arranged in a stepped shape, and the driven worm gear 54 is located on the side of the driving worm gear 51 close to the mounting seat 14, and a plurality of limiting grooves 513 for sliding connection of the driven worm gear 54 are evenly provided on the inner side wall of the driving worm gear 51 along its axial direction, and a plurality of limiting protrusions 541 that are slidably adapted to the limiting grooves 513 are protruded on the outer peripheral wall of the driven worm gear 54 in a one-to-one correspondence; a linear driving member 144 is also fixedly installed on the mounting seat 14 for driving the driven worm gear 54 to slide back and forth on the driving worm gear 51 in a direction parallel to its axis, and the driven worm gear 54 is movably engaged with the worm 52. The driven worm gear 54 is used to cooperate with the driving worm gear 51 to enhance the load-bearing capacity of the rotation locking structure 5 between the drill arm 13 and the drill frame 3 and the relative stability during the load-bearing process.

[0056] In order to realize the coordinated transmission of the driving worm gear 51 and the driven worm gear 54 and the worm 52, refer to Figure 4 and Figure 5 , and combined with Figure 3The driven worm gear 54 is coaxially connected to the inner side of the driven worm gear 54 in a non-slip manner. The linear drive member 144 is a drive cylinder, which can be any one of an air cylinder, a hydraulic cylinder or an oil cylinder. The rotating ring 55 is connected to the mounting shaft 15 along the axial sliding direction of the mounting shaft 15.

[0057] In a feasible embodiment of the present application, the rotating ring 55 can be a metal ring with stronger magnetism than the driving worm gear 51 and the driven worm gear 54. One end of the linear driving member 144 is vertically and fixedly connected to the bottom wall of the disk body 141 of the mounting seat 14, and the other end is fixedly installed with an electromagnetic member. The operator can adjust the distance between the rotating ring 55 and the bottom wall of the disk body 141 of the mounting seat 14 accordingly by controlling the magnetic force of the electromagnetic member on the rotating ring 55, thereby realizing the movable engagement between the driven worm gear 54 and the worm 52; and in this feasible embodiment, when the operator uses the worm 52 and the driving worm gear 51 to drive the drill rig 3 to rotate on the drill arm 13, the driving worm gear 51 and the worm 52 play a major driving role in controlling the rotation of the drill rig 3 on the drill arm 13.

[0058] The electromagnetic element at the end of the linear drive member 144 magnetically attracts the rotating ring 55, which then drives the driven worm gear 54 linearly toward the worm 52, meshing the driven worm gear 54 with the worm 52. The electromagnetic element's current is intermittently controlled during the rotation of the driving worm gear 51, enabling the driven worm gear 54 to cooperate with the driving worm gear 51, achieving a dual multi-tooth meshing transmission with the worm 52. This ensures smoother transmission between the worm 52 and the worm wheel, effectively enhancing the load-bearing capacity of the driving worm gear 51 and the stability of the drill rig 3 when rotating on the drill boom 13 and when locked relative to the drill boom 13, thereby achieving stable and convenient angle adjustment of the drill rig 3 on the drill boom 13 and stable drilling. Furthermore, in this feasible embodiment, the magnetic attraction of the electromagnetic element is sufficiently strong to apply a certain magnetic attraction force to the driving worm gear 51 and the driven worm gear 54, further braking the driving worm gear 51 and the driven worm gear 54 when the worm 52 stops rotating.

[0059] In another feasible embodiment of the present application, the two ends of the linear drive member 144 are respectively perpendicularly and fixedly connected to the mounting seat 14 and the rotating ring 55; and in this feasible embodiment, the driving worm gear 51 and the worm 52 still play the main driving role in controlling the rotation of the drill frame 3 on the drill arm 13, and the driven worm gear 54 can also cooperate with the driving worm gear 51 to brake and lock the worm 52. This feasible embodiment is more economical and practical than the above-mentioned electromagnetic component.

[0060] And in the above feasible embodiments, refer to Figure 3 、 Figure 4 and Figure 5, a plurality of guide grooves 152 are evenly arranged on the outer peripheral wall of the mounting shaft 15 along its axial direction for cooperating with the linear drive member 144 to limit and guide the sliding of the rotating ring 55, and a plurality of guide protrusions 551 that are slidably adapted to the guide grooves 152 are protruded on the inner side of the rotating ring 55 in a one-to-one correspondence; at the same time, when the linear drive member 144 and the rotating ring 55 are stationary relative to the mounting shaft 15, as the driving worm gear 51 and the driven worm gear 54 rotate relative to the mounting shaft 15, the guide protrusions 551 and the guide grooves 152 can also share the friction force in the circumferential direction of the driven worm gear 54 on the rotating ring 55, thereby reducing the torque force on the linear drive member 144 and ensuring the normal operation of the linear drive member 144.

[0061] At the same time, the plurality of columns 512 and the ring body 511 make the driving worm gear 51 and the driven worm gear 54 actually special-shaped worm gears different from traditional toothed worm gears.

[0062] On the one hand, the operator can customize the driving worm gear 51 according to the minimum spacing between two adjacent holes in actual construction specifications / construction experience, so that the angle formed by the two adjacent columns 512 on the driving worm gear 51 / driven worm gear 54 and the axis of the driving worm gear 51 / driven worm gear 54 can more accurately and effectively adapt to the minimum spacing between two adjacent holes when the worm 52 rotates a certain number of circles or a certain angle; the operator can more conveniently control the rotation of the drill rig 3 by controlling the number of rotation circles / rotation angle of the worm 52, so that the pre-drilling position of the drilling tool 4 can more accurately and conveniently coincide with the actual position of the hole to be drilled.

[0063] On the other hand, the column 512 is arranged in the axial direction of the ring body 511 rather than the circumferential direction. The position layout of the column 512 and the ring body 511 is conducive to the more convenient installation of the driven worm gear 54 to the inner side of the driving worm gear 51, and ensures the sliding of the driven worm gear 54 on the driving worm gear 51 and the active engagement of the driven worm gear 54 with the worm 52, which is conducive to realizing and controlling the double multi-tooth engagement transmission process of the driven worm gear 54 and the driving worm gear 51 to the worm 52.

[0064] Furthermore, in order to facilitate the operator to detachably replace the drill frame 3 and the drilling tool 4 on the drill arm 13 according to the different diameters of the holes to be drilled, Figure 2 and Figure 3 The universal joint 31 is detachably fixedly mounted on the rotating arm. A plurality of sets of bolts 32 are evenly arranged on one side of the universal joint 31 close to the drill frame 3 . The universal joint 31 is fixedly mounted on the driving worm gear 51 through the plurality of sets of bolts 32 .

[0065] The operator can achieve detachable fixation of the universal joint 31 and the driving worm gear 51 by screwing and removing multiple groups of bolts 32, thereby achieving detachable replacement of the drill rig 3 and the drill tool 4 on the drill arm 13, which is convenient for the operator to quickly replace the drill rig 3 and the drill tool 4 on the rock drilling equipment according to the actual size of the hole to be drilled, thereby improving the adaptability of the rock drilling equipment to the hole diameter required for drilling holes under different geological conditions and effectively ensuring the connection stability of the drill rig 3 and the drill arm 13.

[0066] Combine Figure 4 , the worm 52 and the driving component 53 are also provided with two groups accordingly, and the two groups of worm 52 and the driving component 53 are respectively located on the upper and lower sides of the installation shaft 15, and the two groups of worm 52 are parallel to each other, and the distance between the two groups of worm 52 and the installation shaft 15 is consistent, and the two groups of worm 52 rotate in opposite directions; the two groups of worm 52 and the driving component 53 are used to simultaneously engage and transmit the active worm wheel 51, and the two groups of worm 52 have a more compact structure. Compared with the transmission of a single group of worm 52, the two groups of worm 52 can obtain a better meshing effect than a single group of worm 52, and the load capacity between the active worm wheel 51 and the worm 52 is also higher. The angle adjustment of the drill frame 3 on the drill arm 13 and the drilling of the drill tool 4 on the drill frame 3 are correspondingly more stable.

[0067] Replay Figure 1 The drill frame 3 is a straight, long strip frame, the upper side and the lower side of the drill frame 3 are both planes, and the upper side plane of the drill frame 3 is parallel to the lower side plane.

[0068] The lower plane of the drill rig 3 is connected to the universal joint 31, and the upper top of the drill rig 3 is equipped with a power component for driving the main drill rod 41 in the drilling tool 4 to drive the drill bit and the hammer to impact the ground, rock surface or other surface to be drilled and perform drilling; the power component can be part of the hydraulic power system, or it can be detachably assembled to the hydraulic power system on the side of the frame 1 and the drilling rig body 2 through a pipe joint or an electric plug / socket, thereby cooperating with the universal joint 31 and the driving worm gear 51 to realize the detachable assembly of the drill rig 3 of the rock pile drilling equipment and the stable operation of the hydraulic power system.

[0069] A positioning light 33 emitting linear light toward one side is also fixedly installed at the lower end of the upper side of the drill frame 3. The positioning light 33 is arranged adjacent to the main drill rod 41. The light emission direction of the positioning light 33 is parallel to the main drill rod 41, and the distance between the positioning light 33 and the main drill rod 41 is preferably between 5-10 cm; the light emitting end of the positioning light 33 faces downward, and the light emitted by the positioning light 33 diffuses outward relative to the position of the positioning light 33, and the light emitted by the positioning light 33 can form a circular light spot with a radius of at least 3 cm on the ground. The opening and closing of the positioning light 33 is controlled by the down-the-hole drill central integrated control system in the drilling rig body 2; the operator can observe the circular light spot of the positioning light 33 on the ground, rock surface or other surface to be drilled in the cab, and predict and locate the pre-drilling position corresponding to the drill bit and the impactor through the circular light spot.

[0070] A fixing assembly 34 for connecting the drill rig 3 to the ground is also fixedly installed at the lower end of the drill rig 3. After the operator moves the drill rig 3 and the drilling tool 4 to the predetermined working position, the operator can use the fixing assembly 34 to connect and fix the drill rig 3 to the ground, thereby making the drill rig 3 and even the rock drilling equipment as a whole more stable on the ground during the drilling process.

[0071] Reference Figure 1 The fixing assembly 34 specifically includes a fixing plate 341 protruding and vertically fixed to the lower side of the drill frame 3, a fixed blade 3 integrally connected to the lower side of the fixing plate 341, and a fixing nail 343 movably provided on the fixing plate 341; the fixed blade 3 has a certain thickness and length, and the side of the fixed blade 3 close to the fixing plate 341 is its upper side, the cross-sectional area of ​​the fixed blade 3 gradually decreases from its upper end to its lower end, and the fixed blade 3 is thick in the middle and thin on both sides, and the lower end of the fixed blade 3 protrudes outside the lower end of the drill frame 3 to increase the pressure between it and the ground, rock surface or other surface to be drilled, so that the fixed blade 3 is more convenient to insert into the ground The fixing nail 343 can be a pile body with a thick top and a narrow bottom, such as a steel pile / a wooden pile / a bamboo pile. There are multiple fixing nails 343, and the multiple fixing nails 343 are evenly surrounded by the side of the fixed blade 3, and the fixing nails 343 vertically penetrate the fixing plate 341 from top to bottom. The lower end of the fixing nail 343 is suitable for nailing into the ground, rock surface or other surfaces to be drilled, so as to achieve relative fixation of the drill frame 3 and the ground, rock surface or other surfaces to be drilled, so that after the operator uses the drill arm 13 and the rotation locking mechanism 5 to move the drill frame 3 and the drill tool 4 to the specified position, the drilling stability of the rock drilling equipment at the established work station is further guaranteed.

[0072] The implementation principle of a rock drilling device that is convenient for construction in the embodiment of the present application is as follows: when drilling is required at a certain place on the ground, rock surface or other surface to be drilled, the operator can first use the walking crawler 11 and the hydraulic power system to preliminarily move the device to a working position (i.e., a working station) adjacent to the drilling hole, and make the walking crawler 11, the frame 1 and the drilling rig body 2 no longer move; then, the operator can horizontally rotate the drilling rig body 2 and the drill arm 13 in the cab, turn on the rear light, and swing the drill arm 13 back and forth, so that the drill frame 3 drives the drill tool 4 to move above the position to be drilled, thereby achieving preliminary positioning of the pre-drilling position and the position to be drilled; then, the operator can control the drive motor and the linear drive member 144, and drive the drill frame 3 relative to the mounting seat 14 (i.e., The drill arm 13) is rotated to adjust the angle of the pre-drilling position of the rock drilling equipment so that the pre-drilling position is aligned with the position to be drilled, and the fixing component 34 is used to fix the drill frame 3 and the surface to be drilled to perform stable drilling; when there are multiple adjacent positions to be drilled, after the drilling is completed, the operator does not need to move the drill body 2 and the work station where the frame 1 is located, nor does he need to adjust the rotation amplitude of the swing arm. He only needs to control the drive motor and the linear drive member 144, and then drive the drill frame 3 to rotate relative to the mounting seat 14 (i.e., the drill arm 13). By repeating the above positioning action, multiple holes can be drilled at one work station without moving the frame 1 and the drill body 2 or the swing arm for each hole, thereby effectively reducing the drilling gap. The above operation is relatively simple, and it is convenient for the operator to adjust the position and angle of the drill rig 3 and the drill tool 4; and the rock drilling equipment in this application has a larger rotation radius than the traditional down-the-hole drill, and the angle adjustment range between the drill rig 3 and the drill arm 13 is also smaller than the drill arm 13, which is more convenient to control, and effectively reduces the difficulty of the operator to fine-tune the drill tool 4, thereby effectively improving the construction efficiency.

[0073] The present application also discloses a rock drilling construction process, based on the above-mentioned rock drilling equipment that is easy to construct, including the following steps:

[0074] S1: Using the walking crawler 11 to initially move the rock drilling equipment to the working position;

[0075] S2: The central integrated control system of the down-the-hole drill drives the hydraulic power system to drive the cab and the drill arm 13 to rotate horizontally, so that the position to be drilled is within the forward and backward swing range of the drill arm 13 to the left / right 0.2-0.5m. The drill arm 13 is then swung forward and backward to its working position and the drill arm 13 is stationary relative to the frame 1, so that the projection of the drill frame 3 and the drilling tool 4 on the ground covers the position to be drilled;

[0076] S3: Use the positioning light 33 to locate the pre-drilling position of the drill bit and the hammer. When the pre-drilling position coincides with the position to be drilled, use the fixing assembly 34 to fix the drill gantry 3 and the ground, and control the main drill rod 41 to drive the drill bit and the hammer to drill. When there is an offset between the pre-drilling position and the drilling position, use the driving component 53 to drive the drill gantry 3 and the main drill rod 41 to rotate relative to the drill arm 13, and fine-tune the position of the main drill rod 41 so that the pre-drilling position coincides with the position to be drilled. Then control the main drill rod 41 to drive the drill bit and the hammer to drill.

[0077] S4: After the drilling is completed, the drill frame 3 is unlocked from the ground, the drill arm 13 is retracted, and the rock drilling equipment is preliminarily moved to the next working position using the walking crawler 11, and the above steps are repeated.

[0078] The implementation principle of a rock drilling construction process in an embodiment of the present application is as follows: by utilizing the worm gear 52 structure to rotate the drill rig 3 and install it on the drill arm 13, and utilizing the rotation locking mechanism 5 to drive and control the rotation of the drill rig 3 on the drill arm 13, the rock drilling equipment can more conveniently realize the position and angle adjustment of the drill rig 3 and the drill tool 4 after moving to the working position, so that the pre-drilling position can be more conveniently aligned with the position to be drilled, and multiple holes can be drilled at one work station without moving one hole at a time, which effectively reduces the drilling gap, reduces the control difficulty and effectively improves the construction efficiency.

[0079] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
