Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to drilling equipment and a control method thereof. Background Art

[0002] In recent years, as the country attaches great importance to transportation construction, the expansion of highways and railways has also increased, and the construction of tunnels has also increased. In the process of tunnel construction, mechanized operations are becoming more and more widespread. In particular, the popularization of rock drilling equipment has greatly improved construction efficiency.

[0003] In some construction environments where the drilling holes are deep, there are manual rod connection or automatic rod connection methods to solve the problem. Especially for holes with a depth of about six meters, the expected hole depth is usually achieved by connecting rods. This process inevitably causes labor consumption and time consumption due to connecting rods.

[0004] The traditional method of using a long drill rod for one-time forming greatly improves the hole-making efficiency compared with the former, but it also faces the problem of serious rod throwing due to the long rod during the rotation of the rock drill, which can easily cause relatively poor hole-making quality. More importantly, rod throwing can easily cause the drill rod to deform and break during the rock drilling process, and the connecting sleeve and the drill tail end are also prone to early wear due to the eccentric staggered stress caused by rod throwing, ultimately increasing the cost of the entire construction process. Summary of the invention

[0005] In view of this, the present invention provides an auxiliary drill supporting device, a drilling device and a control method thereof to solve the problems of poor hole quality, deformation and breakage of the drill rod and large loss caused by the swinging of the rod during the rotation of the rock drill.

[0006] In the first aspect, the present invention provides a drilling device, including a propulsion beam and an auxiliary drill supporting device arranged on the propulsion beam, wherein the auxiliary drill supporting device includes an assembly base, a swing arm assembly and a drill supporting assembly. The assembly base is suitable for being connected to the propulsion beam; the swing arm assembly is rotatably connected to the assembly base; the drill supporting assembly is connected to the swing arm assembly and is suitable for swinging with the swing arm assembly relative to the assembly base, the drill supporting assembly includes a fixed clamp block and a movable clamp block, the fixed clamp block is fixedly connected to the swing arm assembly, the movable clamp block is rotatably connected to the fixed clamp block through a rotating shaft, when the movable clamp block is closed with the fixed clamp block, a supporting channel for supporting the drill rod of the drilling device is formed between the movable clamp block and the fixed clamp block, and the extension direction of the supporting channel is the same as the axial direction of the rotating shaft; the auxiliary drill supporting device has a drill supporting working position and an avoidance working position, in which the fixed clamp block and the movable clamp block are closed, and the swing arm assembly is close to the drill rod; in the avoidance working position, the fixed clamp block and the movable clamp block are opened, and the swing arm assembly is away from the drill rod; the swing arm assembly and the drill supporting assembly are suitable for switching the auxiliary drill supporting device between the drill supporting working position and the avoidance working position.

[0007] Beneficial effects: The drilling equipment provided by the present invention has an auxiliary drill support device on the propulsion beam. When the fixed clamp block and the movable clamp block in the drill support assembly are closed, a support channel is formed between the two. The drill rod passes through the support channel, and a gap is left between the drill rod and the support channel instead of locking the drill rod, allowing the drill rod to rotate in the support channel. At the same time, the fixed clamp block and the movable clamp block in the drill support assembly can stably support the drill rod, so that the drill rod is effectively supported and stabilized during the rotation process, greatly reducing the rod throwing phenomenon caused by the rod length, ensuring the straightness of the drill rod during the drilling process, and thus improving the quality of the hole. In addition, the present invention can prevent it from offsetting or vibrating during the rotation process, effectively reducing the eccentric staggered stress caused by the rod throwing of the connecting sleeve and the drill tail end, avoiding early wear, preventing the drill rod from deforming or breaking, extending the service life of the drill rod and related components, reducing the frequency of replacement due to wear and damage, and reducing material costs.

[0008] In a second aspect, the present invention provides a method for controlling the drilling equipment in the above technical solution, comprising the following steps:

[0009] Step S10, the rock drill device is working, and the propulsion drive device pushes the rock drill device and the drill support device to move forward along the propulsion beam;

[0010] Step S20, the support plate of the drill support device triggers the position sensor, the position sensor sends a signal to the controller, the controller collects and processes the signal, the controller controls the auxiliary drill support device to move, the fixed clamp block and the movable clamp block of the drill support assembly are opened, the swing arm assembly is away from the drill pipe, and the auxiliary drill support device is switched to the avoidance working position;

[0011] Step S30, the drill rod is drilled to complete a drilling;

[0012] Step S40, the drill support device is retracted, and after the support plate of the drill support device triggers the position sensor, the position sensor sends a signal to the controller, and the controller collects and processes the signal. The controller controls the auxiliary drill support device to move, the swing arm assembly approaches the drill pipe, the fixed clamp block and the movable clamp block of the drill support assembly are closed, and the auxiliary drill support device is switched to the drill support working position;

[0013] Steps S10 to S40 are looped until the designed drilling depth is reached and the drilling is completed.

[0014] Beneficial effects: The control method provided by the present invention is simple to control, safe and reliable, and has high construction efficiency. It is sensed by the position sensor and executed by the drive cylinder. It has high sensing sensitivity and rapid response. During operation, the time-consuming steps of adjusting the starting drill rod, the lengthened drill rod and the rock drill tail to be concentric during the automatic and manual rod connection are omitted. It also eliminates the time-consuming steps of replacing the lengthened drill rod and connecting the starting drill rod after the drilling is completed. In addition, during the control process, action sequence integration is adopted, and each action does not need to rely on manual intervention before it can be executed. Therefore, it avoids the manual intervention of traditional single actions and improves the execution efficiency of the actions. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] In the existing tunnel rock drilling, especially the hole with a drilling depth of about six meters, the selection methods include manual connecting rod, automatic connecting rod and single long drill rod 31 and other construction methods.

[0032] Manual joints require human intervention and have disadvantages such as low construction efficiency and increased labor costs.

[0033] Although the automatic rod-jointing solves most of the drawbacks of manual rod-jointing, the cost of the automatic rod-jointing vehicle is significantly higher than that of ordinary rock drills due to the relatively complex technology and technical integration, and the time loss caused by rod-jointing is also inevitable. More importantly, for a rock drilling hole depth of about six meters, if there is no limit on the size of the tunnel space, the rock drill with automatic rod-jointing is really a waste of resources and fails to bring into full play its true performance.

[0034] As for the rock drilling vehicle with a single long drill rod 31, although the cost of the whole vehicle is low, it is difficult to choose due to many disadvantages caused by the long drill rod 31 being thrown during the rapid rotation of the rock drilling machine during construction.

[0035] Therefore, in order to solve the defect of the single long drill rod 31 being thrown off, the present invention adds an automatic auxiliary drill support device 10 on the rock drilling propulsion beam 20, so that the single long drill rod 31 can be "as stable as a mountain" in the stage of easy throwing off. Therefore, compared with the other two, the single long drill rod rock drilling vehicle can reduce the vehicle purchase cost, stabilize the construction, and improve the construction efficiency.

[0036] Combine the following Figures 1 to 12 , describing an embodiment of the present invention.

[0037] According to an embodiment of the present invention, in a first aspect, a drilling device 100 is provided, comprising a propulsion beam 20 and an auxiliary drill supporting device 10 arranged on the propulsion beam 20, wherein the auxiliary drill supporting device 10 comprises an assembly base 11, a swing arm assembly 12 and a drill supporting assembly 13. The assembly base 11 is suitable for being connected to the propulsion beam 20; the swing arm assembly 12 is rotatably connected to the assembly base 11; the drill supporting assembly 13 is connected to the swing arm assembly 12, and is suitable for swinging with the swing arm assembly 12 relative to the assembly base 11, and the drill supporting assembly 13 comprises a fixed clamp block 131 and a movable clamp block 132, wherein the fixed clamp block 131 is fixedly connected to the swing arm assembly 12, and the movable clamp block 132 is rotatably connected to the fixed clamp block 131 via a rotating shaft 133, and when the movable clamp block 132 and the fixed clamp block 131 are closed, a support for the drill supporting device is formed between the movable clamp block 132 and the fixed clamp block 131. The supporting channel 134 of the drill rod 31 of the drilling equipment 100 extends in the same direction as the axial direction of the rotating shaft 133; the auxiliary drill supporting device 10 has a drill supporting working position and an avoidance working position. In the drill supporting working position, the fixed clamp block 131 and the movable clamp block 132 are closed, and the swing arm assembly 12 is close to the drill rod 31; in the avoidance working position, the fixed clamp block 131 and the movable clamp block 132 are opened, and the swing arm assembly 12 is away from the drill rod 31; the swing arm assembly 12 and the drill supporting assembly 13 are suitable for switching the auxiliary drill supporting device between the drill supporting working position and the avoidance working position.

[0038] In the drilling equipment provided by the embodiment of the present invention, an auxiliary drill support device 10 is arranged on the propulsion beam 20. When the fixed clamp block 131 and the movable clamp block 132 in the drill support assembly 13 are closed, a support channel 134 is formed between the two, and the drill rod 31 passes through the support channel 134. A gap is left between the drill rod 31 and the support channel 134 instead of locking the drill rod 31, allowing the drill rod 31 to rotate in the support channel 134. At the same time, the fixed clamp block 131 and the movable clamp block 132 in the drill support assembly 13 can stably support the drill rod 31, so that the drill rod 31 is effectively supported and stabilized during the rotation process, greatly reducing the rod throwing phenomenon caused by the rod length, ensuring the straightness of the drill rod 31 during the drilling process, thereby improving the quality of the hole. In addition, the present invention can prevent it from deflecting or vibrating during the rotation process, effectively reducing the eccentric staggered stress caused by the rod throwing of the connecting sleeve and the drill tail end, avoiding early wear, preventing the drill rod from deforming or breaking, extending the service life of the drill rod 31 and related components, reducing the frequency of replacement due to wear and damage, and reducing material costs.

[0039] Specifically, the auxiliary drill supporting device 10 is fixed on the propulsion beam 20 as a whole through the assembly base 11. The swing arm assembly 12 can drive the drill supporting assembly 13 to swing, so as to approach the drill rod 31 when the drill rod 31 needs to be supported, or to move away from the drill rod 31 when the drill rod 31 needs to be released. The drill supporting assembly 13 is used to support or release the drill rod 31.

[0040] When the rock drill device 30 starts working, the movable jaw 132 rotates away from the fixed jaw 131, and the two are opened to release the drill rod 31. Then, the swing arm assembly 12 drives the drill support assembly 13 to swing, so that the movable jaw 132 and the fixed jaw 131 are away from the drill rod 31, so that the drill rod 31 can be pushed forward. Subsequently, the rock drill device 30 continues to move forward to complete a drilling.

[0041] Before the second drilling, the swing arm assembly 12 drives the drill support assembly 13 to swing, so that the movable clamp block 132 and the fixed clamp block 131 are close to the drill rod 31, and the movable clamp block 132 rotates close to the fixed clamp block 131, and the two are closed to support the drill rod 31, that is, the auxiliary drill support device is reset before the second drilling. This reciprocating process completes the subsequent drilling.

[0042] In some embodiments, the swing arm assembly 12 includes a swing arm 121 and a swing arm driving member. One end of the swing arm 121 is rotatably connected to the assembly base 11, and the other end of the swing arm 121 is connected to the driving end of the swing arm driving member. The swing arm driving member is suitable for driving the swing arm 121 to swing relative to the assembly base 11.

[0043] Specifically, the rotational connection between the swing arm 121 and the assembly base 11 allows the swing arm 121 to swing freely within a certain range, so that the entire device can flexibly adjust the working posture according to actual needs and adapt to different working environments and task requirements. For example, the swing drive drives the swing arm assembly 12 to approach the drill rod 31, so that the drill support assembly 13 supports the drill rod 31, which plays an auxiliary supporting effect. Alternatively, the drill support assembly 13 releases the drill rod 31, at which time, the swing arm drive drives the swing arm 121 away from the drill rod 31, thereby avoiding hindering the advancement or retraction of the drill rod 31.

[0044] In some embodiments, the swing arm driving member includes a swing arm driving cylinder 122, one end of the swing arm driving cylinder 122 is rotatably connected to the assembly base 11, and the other end of the swing arm driving cylinder 122 is rotatably connected to the other end of the swing arm 121; the fixed clamp 131 is fixedly connected to the swing arm 121.

[0045] Since both ends of the swing arm driving cylinder 122 are connected in a rotational manner, the swing arm 121 can swing freely within a larger range, thereby satisfying the swing arm 121 to achieve a large angle of swing.

[0046] As a direct driving component, the swing arm driving cylinder 122 can realize precise control of the angle and position of the swing arm 121, ensuring that each action can achieve the expected effect, so as to improve the high-precision auxiliary effect on the drill rod 31.

[0047] By using the swing arm drive cylinder 122 to replace the traditional gears or other complex transmission mechanisms, not only the number of parts is reduced, the manufacturing cost is reduced, but also maintenance is made easier. At the same time, the swing arm drive cylinder 122 can complete the same function in a smaller space, thereby saving installation space, and is particularly suitable for compact equipment. In addition, the swing arm drive cylinder 122 can quickly respond to control signals and achieve rapid start and stop, which is conducive to improving construction efficiency.

[0048] Specifically, the swing arm driving cylinder 122 can be an oil cylinder, a pneumatic cylinder or an electric cylinder.

[0049] In some embodiments, the swing arm 121 includes a swing arm base 1211 and a swing arm body 1212. The swing arm base 1211 is rotatably connected to the assembly base 11. One end of the swing arm body 1212 is fixedly connected to the swing arm base 1211, and the other end of the swing arm body 1212 is rotatably connected to the other end of the swing arm drive cylinder 122.

[0050] The swing arm 121 is divided into a swing arm base 1211 and a swing arm body 1212, and a reasonable connection method is used to achieve higher flexibility and stronger adaptability, and facilitate production and maintenance. The swing arm body 1212 is directly driven by the swing arm drive cylinder 122, which reduces the intermediate transmission links, thereby improving the response speed and dynamic performance of the system.

[0051] In addition, the swing arm drive cylinder 122 directly acts on the end of the swing arm body 1212, which optimizes the force transmission path, reduces energy loss, and improves work efficiency.

[0052] In some embodiments, the drill support assembly 13 further includes a drill support driving cylinder 135 , one end of which is rotatably connected to the swing arm assembly 12 , and the other end of which is rotatably connected to the movable clamp 132 .

[0053] The rotational connection between the drill support drive cylinder 135 and the swing arm assembly 12 and the movable jaw block 132 provides an additional degree of freedom for the drill support assembly 13, so that it can more flexibly adapt to different working postures and position requirements. The drill support drive cylinder 135 can drive the movable jaw block 132 to rotate about the rotating shaft 133, so as to drive the movable jaw block 132 to approach the fixed jaw block 131, until the movable jaw block 132 and the fixed jaw block 131 are clamped and closed to form a supporting channel 134, so as to effectively support the drill rod 31; or drive the movable jaw block 132 away from the fixed jaw block 131, so as to open the movable jaw block 132 and the fixed jaw block 131, so as to release the drill rod 31.

[0054] By applying force to the movable clamp block 132 through the drill support driving cylinder 135, accurate control of the drill support action can be achieved, ensuring that each operation can achieve the expected effect, which is conducive to high-precision positioning to smoothly support the drill rod 31.

[0055] Compared with other complex transmission mechanisms, the use of the support rod drive cylinder 135 simplifies the mechanical structure, reduces the manufacturing cost, and is also convenient for later maintenance. At the same time, the support rod drive cylinder 135 can directly respond to the control signal, start and stop quickly, improve the response speed and dynamic performance of the system, and thus improve the overall construction efficiency.

[0056] In some embodiments, two swing arms 121 are arranged in parallel, two movable clamps 132 and two fixed clamps 131 are arranged, and the two movable clamps 132 are arranged between the two swing arms 121. The supporting surface of the movable clamp 132 and the supporting surface of the fixed clamp 131 do not overlap along the length extension direction of the supporting channel 134.

[0057] By arranging two swing arms 121, two movable clamps 132 and two fixed clamps 131 in parallel, the supporting surface of the movable clamp 132 and the supporting surface of the fixed clamp 131 do not overlap along the length direction of the supporting channel 134, so that the contact area with the drill rod 31 can be increased in the length direction of the drill rod 31 to ensure that the drill rod 31 is stably supported.

[0058] In addition, placing the clamp block assembly between the two swing arms 121 fully utilizes the limited space and makes the entire device structure more compact.

[0059] In some embodiments, the fixed clamp block 131 and the swing arm body 1212 are an integrally formed structure.

[0060] By integrally forming the fixed clamp block 131 and the swing arm body 1212, the connection point between the two is eliminated, thereby significantly enhancing the rigidity and strength of the overall structure, thereby improving the supporting effect on the drill rod 31 and effectively avoiding many adverse effects caused by the rod being thrown during the rock drilling process of a single long drill rod 31.

[0061] Compared with the traditional split design, one-piece molding can reduce the number of parts and assembly processes, reduce manufacturing complexity and cost, and also help improve production efficiency.

[0062] With no additional connecting parts, the one-piece design reduces potential points of failure, lowering the need and cost of routine maintenance.

[0063] In some embodiments, at least one shock absorber 14 is further included, and the shock absorber 14 is connected to the swing arm assembly 12 .

[0064] By setting the shock absorber 14, the vibration caused by the impact or movement generated during the drilling process of the drill rod 31 can be effectively absorbed and attenuated, preventing these vibrations from being transmitted to the swing arm assembly 12 and other connected components, thereby improving the stability and reliability of the entire system, improving the auxiliary drilling effect of the drill rod 31, and avoiding rod throwing.

[0065] At the same time, by providing the shock absorber 14, the impact force borne by the swing arm drive cylinder 122, the support drill drive cylinder 135 and other key components can also be reduced, thereby extending their service life and reducing the failure rate.

[0066] In addition, the provision of the shock absorber 14 can also reduce the noise caused by vibration and reduce the construction noise of the drilling equipment 100 when it is working.

[0067] In some embodiments, two components connected by a rotating shaft are provided with a spacer 15 on the rotating shaft to limit the rotating components.

[0068] In some embodiments, the drilling equipment 100 further includes a rock drill device 30, a drill support 40, a propulsion drive device 50 and a top frame device 60 arranged on the propulsion beam 20. The rock drill device 30 includes a drill rod 31; the propulsion drive device 50 is suitable for pushing the rock drill device 30 and the drill support 40 to perform reciprocating linear motion along the propulsion beam 20; the drill rod 31 passes through the drill support hole of the drill support 40 and the center hole of the top frame device 60 in sequence, and the auxiliary drill support device 10 is connected to the propulsion beam 20 and is located between the rock drill device 30 and the top frame device 60.

[0069] Specifically, the propulsion beam 20 serves as a supporting structure of the entire device and is used to install and fix other components.

[0070] The rock drill device 30 includes a drill rod 31 and is responsible for the actual drilling operation. The rock drill device 30 is mounted on the propulsion beam 20 and is driven by the propulsion drive device 50 to perform reciprocating linear motion along the propulsion beam 20 .

[0071] The drill support device 40 is provided with a drill support hole, and the drill rod 31 passes through the drill support hole, so as to reduce the rod throwing situation of the drill rod 31 during the construction process.

[0072] The propulsion drive device 50 can push the rock drill device 30, the cable drum device 80, and the drill support device 40 to perform reciprocating linear motion along the propulsion beam 20, thereby providing the thrust and pull required for drilling.

[0073] A center hole is provided at the center of the top frame device 60, and the drill rod 31 also passes through the hole to play a supporting and guiding role, thereby ensuring the stability of the drill rod 31 during the drilling process. When the auxiliary drill supporting device 10 supports the drill rod 31, the drill rod 31 also passes through the supporting channel 134. The auxiliary drill supporting device 10 can not only play an effective drill supporting effect, but also guide the drill rod 31 through the supporting channel 134.

[0074] During the initial drilling process of a single long drill rod 31, although a drill support 40 is arranged in the middle of the propulsion beam 20, the drill rod 31 is too long and in the initial stage of drilling, the drill support 40 is far away from the top frame device 60. The drill rod 31 is deformed and bent by the thrust of the rock drilling propulsion drive device 50. Under the high-speed rotation of the rock drill, due to the eccentricity caused by the deformation and bending, the drill rod 31 between the drill support 40 and the top frame device 60 is thrown off under high-speed rotation, which can easily cause premature damage to various components during the rock drilling process.

[0075] The drilling equipment 100 provided in this embodiment has an auxiliary drill support device 10 disposed on the propulsion beam 20 and located between the rock drill device 30 and the top frame device 60. The auxiliary drill support device 10 is provided so that the drill rod 31 is effectively supported and stabilized during the rotation process, which greatly reduces the rod swinging phenomenon caused by the rod length, ensures the straightness of the drill rod 31 during the drilling process, and thus improves the quality of the hole. In addition, the support channel 134 formed by the fixed clamp block 131 and the movable clamp block 132 in the drill support assembly 13 can stably support the drill rod 31 to prevent it from deflecting or vibrating during the rotation process, effectively reduces the eccentric staggered stress caused by the rod swinging on the connecting sleeve and the drill tail end, avoids early wear, prevents the drill rod from being deformed or broken, prolongs the service life of the drill rod 31 and related components, reduces the frequency of replacement due to wear and damage, and reduces material costs.

[0076] In some embodiments, a position sensor 70 and a controller are also included. The position sensor 70 is arranged on the assembly base 11 or the propulsion beam 20 of the auxiliary drill supporting device 10. The position sensor 70 is communicatively connected with the controller. The position sensor 70 is used to send a position signal to the controller after being triggered. The controller is suitable for controlling the auxiliary drill supporting device 10 to switch between the drill supporting working position and the avoidance working position according to the position signal.

[0077] Through the coordinated work of the position sensor 70 and the controller, the system can realize automated operation, reduce manual intervention, improve work efficiency, and reduce operational difficulty.

[0078] In some embodiments, the swing arm drive cylinder 122 is connected to a first valve block pressure sensor, the support drill drive cylinder 135 is connected to a second valve block pressure sensor, and the first valve block pressure sensor and the second valve block pressure sensor are respectively connected to the controller for communication.

[0079] With this arrangement, the controller combines the signal acquisition and feedback of the position sensor, the first valve block pressure sensor and the second valve block pressure sensor to realize automatic control of the auxiliary drill supporting device 10 and realize rapid switching of the auxiliary drill supporting device 10 between the drill supporting working position and the avoidance working position.

[0080] The drilling equipment 100 provided in this embodiment adds an auxiliary drill support device 10 to the drill rod 31 during the construction stage when the rod is thrown out most seriously, and automatically controls the opening and closing of the drill support assembly 13 and the reciprocating return function of the swing arm assembly 12 in the auxiliary drill support device 10 through the position sensor 70 and the controller, thereby providing reliable protection for the construction of the long drill rod 31. The drilling equipment 100 provided in this embodiment not only reduces the consumption of vulnerable parts caused by the rod throwing out, but also does not affect the original construction scene. For actual construction, it not only saves costs but also improves construction efficiency compared with rock drilling by connecting rods.

[0081] Specifically, in this embodiment, the position sensor 70 is a proximity switch. It is mounted on the propulsion beam 20 through a mounting frame. The support plate of the drill support device 40 is driven by the propulsion drive device 50 and the drill rod 31 to propel along the propulsion beam 20. During this process, the support plate of the drill support device 40 touches the proximity switch, thereby triggering the proximity switch sensor, which sends a signal to the controller, which receives and processes the signal, thereby controlling the action of the auxiliary drill support device 10.

[0082] In some embodiments, the extension and retraction of the swing arm drive cylinder 122 and the drill supporting drive cylinder 135 of the auxiliary drill supporting device 10 are controlled by utilizing the signal transmission and program logic between the controller, the hydraulic valve block pressure signal and the proximity switch, so as to realize the back and forth swinging of the auxiliary drill supporting device 10 and the closing and loosening of the drill supporting assembly 13.

[0083] The system defines the position where the swing arm assembly 12 of the auxiliary drill support device 10 is swung close to the drill rod 31 and the drill support assembly 13 is closed to support the drill rod 31 as the initial point of the program setting. When the rock drill device 30 starts working, the support plate of the drill support device 40 touches the proximity switch, and the proximity switch detects the signal and transmits the signal to the controller. After processing by the controller, an instruction is given to act on the drill support drive cylinder 135. The drill support drive cylinder 135 pushes the movable clamp block 132 to rotate around the rotating shaft 133, and the movable clamp block 132 moves away from the fixed clamp block 131 to release the drill rod 31. Subsequently, the controller receives the hydraulic valve block pressure signal of the drill support drive cylinder 135, and after processing by the controller, an instruction is given to act on the swing arm drive cylinder 122. The swing arm drive cylinder 122 contracts to make the swing arm body 1212 and the swing arm base 1211 swing away from the drill rod 31 around the hinge point. Subsequently, the rock drill device 30, the cable drum device 80, and the drill support device 40 continue to move forward under the action of the propulsion drive device 50 to complete the drilling until the rock drill device 30, the cable drum device 80, the drill support device 40, and the propulsion drive device 50 retreat and return to the starting position, thus completing a drilling cycle.

[0084] During the second drilling, the auxiliary drill support device 10 is controlled to reset, so that the auxiliary drill support device 10 is swung to a position close to the drill rod 31 and the drill support assembly 13 is closed. The controller executes according to the prescribed procedure. First, the swing arm body 1212 and the swing arm base 1211 swing back to a position close to the drill rod 31 under the thrust of the swing arm drive cylinder 122. Then, the controller receives the hydraulic valve block pressure signal of the swing arm drive cylinder 122, and after processing by the controller, it gives an instruction to act on the drill support drive cylinder 135. The drill support drive cylinder 135 pulls the movable clamp block 132 to rotate around the rotating shaft 133 and closes close to the fixed clamp block 131, that is, the reset of the auxiliary drill support device 10 before the second drilling is completed. Subsequently, under the action of the auxiliary drill support device 10, the second drilling cycle is completed, and so on, the subsequent drilling cycles are completed.

[0085] In addition, when encountering construction problems, the auxiliary drill supporting device 10 can also be controlled to evade, that is, the drill supporting assembly 13 is loosened and swung to a position away from the drill rod 31.

[0086] In some embodiments, a reset button is further included, which is communicatively connected to the controller. After being triggered, the reset button is used to send a reset signal to the controller. The controller is suitable for controlling the auxiliary drill supporting device 10 to switch to the drill supporting working position according to the reset signal.

[0087] In this embodiment, by setting a reset button, the auxiliary drill supporting device 10 can be reset by one key through manual operation, that is, the auxiliary drill supporting device 10 is quickly reset to the drill supporting working position. Preferably, in order to avoid manual misoperation of resetting, when the drill supporting device 40 is retracted, the support plate of the drill supporting device 40 triggers the position sensor 70, and the position sensor 70 sends a signal to the controller, and the controller collects and processes the signal. At this time, manual touching of the reset button is effective, and then the controller controls the auxiliary drill supporting device 10 to move, the fixed clamp block 131 and the movable clamp block 132 of the drill supporting assembly 13 are opened, the swing arm assembly 12 is away from the drill rod 31, and the auxiliary drill supporting device 10 is switched to the avoidance working position.

[0088] According to an embodiment of the present invention, in a second aspect, a control method for the above-mentioned drilling equipment is also provided, comprising the following steps:

[0089] Step S10, the rock drill device 30 is working, and the propulsion drive device 50 pushes the rock drill device 30 and the drill support 40 to move forward along the propulsion beam 20;

[0090] Step S20, the support plate of the drill supporting device 40 triggers the position sensor 70, the position sensor 70 sends a signal to the controller, the controller collects and processes the signal, the controller controls the auxiliary drill supporting device 10 to move, the fixed clamp block 131 and the movable clamp block 132 of the drill supporting assembly 13 are opened, the swing arm assembly 12 is away from the drill rod 31, and the auxiliary drill supporting device 10 is switched to the avoidance working position;

[0091] Step S30, the drill rod 31 drills in and completes a drilling operation;

[0092] Step S40, the drill supporting device 40 is retracted, and after the support plate of the drill supporting device 40 triggers the position sensor 70, the position sensor 70 sends a signal to the controller, and the controller collects and processes the signal, and the controller controls the auxiliary drill supporting device 10 to move, the swing arm assembly 12 approaches the drill rod 31, the fixed clamp block 131 and the movable clamp block 132 of the drill supporting assembly 13 are closed, and the auxiliary drill supporting device 10 is switched to the drill supporting working position;

[0093] Steps S10 to S40 are looped until the designed drilling depth is reached and the drilling is completed.

[0094] In some embodiments, the swing arm drive cylinder 122 is connected to a first valve block pressure sensor, the support drill drive cylinder 135 is connected to a second valve block pressure sensor, and the first valve block pressure sensor and the second valve block pressure sensor are respectively connected to the controller for communication;

[0095] Step S20 includes:

[0096] In step S21, the controller sends a control instruction to the drill supporting drive cylinder 135 to control the action of the drill supporting drive cylinder 135, driving the movable clamp block 132 away from the fixed clamp block 131 until the drill supporting drive cylinder 135 is in place, the first valve block pressure sensor sends a first pressure signal to the controller, the controller receives and processes the first pressure signal, sends a control instruction to the swing arm drive cylinder 122 to control the action of the swing arm drive cylinder 122, driving the swing arm 121 and the drill supporting assembly 13 to swing away from the drill pipe 31, until the swing arm drive cylinder 122 is in place, the second valve block pressure sensor sends a second pressure signal to the controller, the controller receives and processes the second pressure signal, and the auxiliary drill supporting device 10 completes switching to the avoidance working position.

[0097] In some embodiments, the drilling device further comprises a reset button, the reset button being communicatively connected to the controller;

[0098] Step S40 includes:

[0099] In step S41, the drill supporting device 40 retracts and triggers the position sensor 70. The position sensor 70 sends a signal to the controller, and the controller collects and processes the signal. The reset button is manually triggered, and the controller receives the position signal and the reset signal, and sends a control instruction to the swing arm drive cylinder 122 to control the swing arm drive cylinder 122 to drive the swing arm 121 and the drill supporting assembly 13 to swing close to the drill rod 31 until the swing arm drive cylinder 122 moves into place. The second valve block pressure sensor sends a second pressure signal to the controller, and the controller receives and processes the second pressure signal. The controller sends a control instruction to the drill supporting drive cylinder 135, and the drill supporting drive cylinder 135 moves to drive the movable clamp block 132 close to the fixed clamp block 131 until the drill supporting drive cylinder 135 moves into place. The first valve block pressure sensor sends a first pressure signal to the controller, and the controller receives and processes the first pressure signal, and the auxiliary drill supporting device 10 completes switching to the drill supporting working position.

[0100] In some embodiments, the specific control logic is as follows:

[0101] At the beginning of rock drilling, the rock drill device 30, the cable drum device 80, and the drill support 40 are all returned to the starting position by default. When the rock drill is started, when the support plate of the drill support 40 touches the position sensor 70, the position sensor 70 detects a signal and transmits it to the controller, which processes the signal and sends a command to the drill support drive cylinder 135. The rodless cavity of the drill support drive cylinder 135 is filled with oil, and the movable clamp block 132 is away from the fixed clamp block 131, and the drill rod 31 is released. When the first valve block pressure sensor connected to the drill driving cylinder 135 obtains the first pressure signal of the pressure change of the rodless chamber of the drill driving cylinder 135, the first pressure signal is transmitted to the controller, the controller processes the first pressure signal and sends a control command to the swing arm driving cylinder 122, the rod chamber of the swing arm driving cylinder 122 is filled with oil, driving the swing arm 121 and the drill supporting assembly 13 to swing away from the drill rod 31, when the second valve block pressure sensor connected to the swing arm driving cylinder 122 feeds back the second pressure signal to the controller, the controller gives a command to stop the rod chamber of the swing arm driving cylinder 122 from filling with oil. Until the rock drill completes drilling and returns to the starting position of the rock drill.

[0102] Before the second drilling, the auxiliary drill supporting device 10 is automatically reset by manually touching the reset button, so that the auxiliary drill supporting device 10 is quickly switched to the drill supporting working position. When the rock drill is started again, the auxiliary drill supporting device 10 continues to complete the above logic and actions to complete the second drilling and subsequent continuous drilling.

[0103] In some embodiments, in order to avoid misoperation of the auxiliary drill support device 10 during resetting, a reset button can only be manually touched after the position sensor 70 is triggered when the drill support device 40 retracts in the program control logic, otherwise the action cannot be performed.

[0104] Specifically, when the support plate of the drill support device 40 is retracted and touches the proximity switch, the proximity switch will send a signal to the controller again. Only when the signal exists and is processed by the controller, manually touching the reset button is effective, otherwise it is invalid.

[0105] As an alternative, in some other embodiments, the drilling device further includes an unlocking key and a reset key, and both the unlocking key and the reset key are communicatively connected to the controller; step S40 includes:

[0106] Step S42, manually triggering the unlocking key, the controller receives the unlocking signal, the controller sends a control instruction to the drill supporting drive cylinder 135, the drill supporting drive cylinder 135 moves, drives the movable clamp block 132 away from the fixed clamp block 131, until the drill supporting drive cylinder 135 moves into place, the first valve block pressure sensor sends a first pressure signal to the controller, the controller receives and processes the first pressure signal, the controller sends a control instruction to the swing arm drive cylinder 122, controls the swing arm drive cylinder 122 to move, drives the swing arm 121 and the drill supporting assembly 13 to swing away from the drill pipe 31, until the swing arm drive cylinder 122 is controlled to move into place, the second valve block pressure sensor sends a second pressure signal to the controller, the controller receives and processes the second pressure signal, and the auxiliary drill supporting device 10 switches to the avoidance working position;

[0107] After manual confirmation, the reset button is manually triggered, and the controller receives the reset signal. The controller sends a control instruction to the swing arm drive cylinder 122 to control the swing arm drive cylinder 122 to move, drive the swing arm 121 and the drill supporting assembly 13 to swing close to the drill pipe 31, and the second valve block pressure sensor sends a second pressure signal to the controller. The controller receives and processes the second pressure signal and controls the swing arm drive cylinder 122 until the action is in place. The controller sends a control instruction to the drill supporting drive cylinder 135, and the drill supporting drive cylinder 135 moves, driving the movable clamp block 132 close to the fixed clamp block 131. The first valve block pressure sensor sends a first pressure signal to the controller. The controller receives and processes the first pressure signal and controls the drill supporting drive cylinder 135 until the action is in place. The movable clamp block 132 and the fixed clamp block 131 are closed, and the auxiliary drill supporting device 10 switches to the drill supporting working position.

[0108] The auxiliary drill supporting device 10 is reset by double buttons, that is, an unlocking button and a reset button are set. The unlocking button must be touched manually to release the auxiliary drill supporting device 10 with one button, so that the auxiliary drill supporting device 10 is located in the avoidance working position. After manual confirmation that the auxiliary drill supporting device 10 is within the safe construction range, the reset button can be touched manually again to place the auxiliary drill supporting device 10 in the drill supporting working position.

[0109] The unlocking button can be used to deal with emergencies and dangerous situations that may occur during the rock drilling process. It is necessary to quickly loosen and swing the drill support assembly to a position away from the drill pipe, thereby improving the safety of the drilling equipment and its ability to respond to emergencies.

[0110] The double-button reset can make the auxiliary drill supporting device 10 be located in the avoidance working position by pressing the unlock button first, and then press the reset button to make the auxiliary drill supporting device 10 be located in the drill supporting working position after a long period of downtime, thereby avoiding the auxiliary drill supporting device 10 not being located in a safe construction state after the last construction, ensuring that the auxiliary drill supporting device 10 will not affect the construction or collide with other components during the current construction, thereby ensuring the safety of the construction.
