[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] like Figure 1 As shown, the integrated anchor drilling rig for anchoring and injection (hereinafter referred to as the anchor drilling rig) of this invention includes a drill frame 10, a drill box base 20, a sliding module 30, a drilling box 40, a pre-tightening drill box 50, a clamping mechanism 60, a sliding seat group 70, and a sliding drive 80.

[0046] The drill frame 10 can be roughly cubic in shape, such as... Figure 1 and Figure 2 As shown, the drill frame 10 can be assembled from plates, rods, etc., and the drill frame 10 generally extends in the vertical direction. The drill box base 20 is fixed to the drill frame 10. For example, the drill box base 20 can be fixed to the bottom of the drill box base 20 and located on the front side of the drill frame 10 by fasteners such as bolts.

[0047] The drill box base 20 may have a slot in the middle, which is generally rectangular and runs vertically through the drill box base 20, with the slot opening facing the front of the drill box base 20. Specifically, the drill box base 20 may be divided into two independent parts, which may be arranged alternately in the left and right directions. The left drill box base 20 may be fixed to the left side of the drill frame 10, and the right drill box base 20 may be fixed to the right side of the drill frame 10. The slot may be formed between the two independent parts of the drill box base 20, thus facilitating the formation of the slot.

[0048] The sliding module 30 fits into the slot and slides along the first direction onto the drill frame 10. For example, as Figure 3 As shown, the sliding module 30 can be a block structure, and can be provided with two guide holes. The drill frame 10 can be provided with two guide posts, both of which extend along a first direction (vertical direction). The two guide posts are slidably assembled into the two guide holes, thereby enabling the sliding module 30 to slide back and forth along the first direction. When the sliding module 30 slides to the bottom of the drill frame 10, it is inserted into the slot of the drill box base 20, so that the sliding module 30 and the drill box base 20 are roughly at the same level, which facilitates the subsequent back and forth switching of the sliding seat assembly 70 on the sliding module 30 and the drill box base 20.

[0049] like Figure 1As shown, the drilling box 40 and the pre-tightening drilling box 50 can be arranged parallel to each other in the left-right direction. The drilling box 40 is fixed with a drill rod 41 for drilling, which extends in the vertical direction. When the drilling box 40 is started, the drill rod 41 can be used to drill into the coal wall. The pre-tightening drilling box 50 can be used to install anchor bolts. When the pre-tightening drilling box 50 is started, the anchor bolts can be sent into the completed borehole. After the anchoring agent in the borehole has cured, the pre-tightening drilling box 50 can also drive the pre-tightening nut, thereby achieving the pre-tightening and fixing of the anchor bolts.

[0050] The anchor bolt has at least two channels for delivering different types of anchoring agent components into the borehole. For example, the anchor bolt may have two channels, both extending along the axial direction of the anchor bolt, with the inlet of each channel located at the bottom of the anchor bolt and the outlet of each channel located at the top of the anchor bolt.

[0051] In use, one channel allows for the introduction of anchoring agent component A, while the other channel allows for the introduction of anchoring agent component B. Components A and B then flow out from their respective channel outlets and can flow in the opposite direction towards the borehole opening, thus filling the gap between the anchor rod and the borehole. It should be noted that components A and B mix and solidify rapidly in the annular space between the anchor rod and the borehole, thereby achieving anchoring of the anchor rod.

[0052] The clamping mechanism 60 is arranged opposite to the sliding module 30 in the first direction, for example, as Figure 1 As shown, the clamping mechanism 60 can be fixed to the top of the drill frame 10. The clamping mechanism 60 can be arranged directly opposite the sliding module 30 in the vertical direction. The clamping mechanism 60 is located on the drill frame 10 and has two clamps. The angle of the two clamps can be opened and closed to make the clamping mechanism 60 have a first form and a second form. In the first form, the clamping mechanism 60 is used to straighten the drill rod 41 or the anchor rod. In the second form, the clamping mechanism 60 allows the drilling box 40 or the pre-tightening drilling box 50 to pass through.

[0053] Specifically, such as Figure 5 As shown, the clamping mechanism 60 may include a base 61 and a clamping assembly 62. The clamping assembly 62 has a first form and a second form and includes a first clamp 621 and a second clamp 622 that can be opened and closed. One end of the first clamp 621 and the second clamp 622 are rotatably connected to the base 61. The other end of the first clamp 621 is provided with a first groove 6211, and the other end of the second clamp 622 is provided with a second groove 6221.

[0054] For example, such as Figures 5 to 7As shown, both the first clamp 621 and the second clamp 622 can be cast parts. Both clamps 621 and 622 can be arranged generally along the front-to-back direction, and can be arranged opposite each other in the left-to-right direction, with the first clamp 621 located to the left of the second clamp 622. The rear ends of both clamps 621 and 622 can be pivotally mounted to the base 61, allowing them to swing relative to each other in the left-to-right direction, thus satisfying the need to adjust the opening angle of the clamps 621 and 622.

[0055] The front end of the first clamp 621 is provided with a first groove 6211, which can be located on the right side of the first clamp 621. The front end of the second clamp 622 is provided with a second groove 6221, which can be located on the left side of the second clamp 622. Both the first groove 6211 and the second groove 6221 can be semi-circular grooves.

[0056] Since the first clamp 621 and the second clamp 622 can swing relative to each other and adjust their opening and closing angles, during the swing adjustment process, the clamp assembly 62 has a first shape, specifically as follows: Figure 5 As shown, at this time, the opening angle of the first clamp 621 and the second clamp 622 can be minimized, and the openings of the first groove 6211 and the second groove 6221 can be aligned and joined together to form a through hole, which is a circular hole. Therefore, the anchor rod and the drill rod 41 can fit into the through hole formed by the joining of the first groove 6211 and the second groove 6221. The hole wall of the through hole can act as a limit, thereby correcting and assisting in the straightening of the anchor rod and the drill rod 41.

[0057] When the opening angle of the first clamp 621 and the second clamp 622 increases, the clamp assembly 62 can switch to the second mode. At this time, as... Figure 6 and Figure 7 As shown, the opening angle formed by the first clamp 621 and the second clamp 622 can be maximized, thereby allowing the size of the space between the first clamp 621 and the second clamp 622 to be larger, which meets the usage requirements for the drilling box 40 and the pre-tightening drilling box 50 to pass through. In addition, it also meets the usage requirements for the passage of large-sized components such as the tray on the anchor rod.

[0058] like Figure 4 As shown, the sliding seat assembly 70 has a first position and a second position and includes a first sliding seat 71 and a second sliding seat 72. Both the first sliding seat 71 and the second sliding seat 72 can be generally square plate structures. The first sliding seat 71 and the second sliding seat 72 are slidably assembled on the drill box base 20 along a second direction (left-right direction) orthogonal to the first direction. A sliding drive 80 is provided on the drill box base 20. The sliding drive 80 can be a telescopic hydraulic cylinder, specifically a single-rod hydraulic cylinder.

[0059] In use, the sliding drive 80 can be connected to the first sliding seat 71 and the second sliding seat 72. Then, by extending and retracting the sliding drive 80, the first sliding seat 71 and the second sliding seat 72 can be synchronously switched between the first position and the second position. Figure 4 The first sliding seat 71 and the second sliding seat 72 are in the first position.

[0060] like Figure 2 As shown, the drilling box 40 is mounted on the first sliding seat 71, and the pre-tightening drilling box 50 is mounted on the second sliding seat 72, as... Figure 2 As shown, at this time, the sliding seat assembly 70 is in the first position. In the first position, the drilling box 40 is located beside the sliding module 30 (which can be on the right side) and is idle. The pre-tightening drilling box 50 is engaged with the sliding module 30 and can slide synchronously with the sliding module 30 in the first direction. When the sliding seat assembly 70 is in the second position, the pre-tightening drilling box 50 is located beside the sliding module 30 (which can be on the left side) and is idle. The drilling box 40 is engaged with the sliding module 30 and can slide synchronously with the sliding module 30 in the first direction.

[0061] The anchor bolt drilling rig of the present invention may include the following steps when in use:

[0062] S1: The sliding seat group 70 can be driven to the second position by the sliding drive 80. At this time, the drilling box 40 slides onto the sliding module 30 through the first sliding seat 71, and the pre-tightening drilling box 50 slides to the side of the sliding module 30 through the second sliding seat 72.

[0063] S2: Switch the clamping mechanism 60 to the first state and clamp the drill rod 41 between the two clamps. The clamping mechanism 60 can play a role in straightening. Then, the drilling box 40 can be started and the sliding module 30 can be driven to move upward, thereby realizing the drilling operation.

[0064] S3: When the drilling box 40 is near the clamping mechanism 60, the clamping mechanism 60 can be switched to the second state, so that the drilling box 40 can pass through the clamping mechanism 60.

[0065] S4: After the drilling is completed, the sliding module 30 can be reset, and then the sliding base can be switched to the first position using the sliding drive 80. At this time, the pre-tightening drill box 50 slides onto the sliding module 30 through the second sliding seat 72, and the drilling drill box 40 slides to the other side of the sliding module 30 through the first sliding seat 71.

[0066] S5: Then the sliding module 30 can be driven to move upward again and the clamping mechanism 60 can be switched to the first state again, so that the anchor rod can be inserted into the borehole. When the tray on the anchor rod and the pre-tightening drill box 50 pass through the clamping mechanism 60, the clamping mechanism 60 can be switched to the second state to improve the passability.

[0067] S6: Then, different anchoring agent components can be pumped into the channel of the anchor bolt via a pumping device.

[0068] S7: After the different anchoring agent components are mixed and cured, the pre-tightening nut can be fixed using the pre-tightening drill box 50, thereby enabling the construction of the anchor rod, and then the pre-tightening drill box 50 can be reset.

[0069] The integrated anchoring and injection drilling rig of this invention simplifies the anchoring process, improves the automation of anchoring, thereby increasing work efficiency and reducing the labor intensity of workers.

[0070] In some embodiments, as shown in 3, the anchor bolt drilling rig includes a limit drive 90, which is disposed in the sliding module 30. For example, the limit drive 90 can be a limit cylinder. The limit drive 90 can be fixed in the sliding module 30, and the driving end of the limit drive 90 can move in the front-back direction.

[0071] Both the first sliding seat 71 and the second sliding seat 72 are provided with limiting holes 73. In the first position, the limiting drive 90 engages with the limiting hole 73 on the second sliding seat 72, thereby connecting and fixing the second sliding seat 72 and the sliding module 30, facilitating the up-and-down movement of the second sliding seat 72 driven by the sliding module 30. When switched to the second position, the limiting drive 90 engages with the limiting hole 73 on the first sliding seat 71, thereby also connecting and fixing the first sliding seat 71 and the sliding module 30, facilitating the up-and-down movement of the first sliding seat 71 driven by the sliding module 30.

[0072] In some embodiments, the sliding drive 80 is located below the sliding base. The sliding drive 80 is provided with a plurality of pins 81. The first sliding base 71 and the second sliding base 72 are detachably connected to the sliding drive 80 through corresponding pins 81, and each pin 81 extends along a first direction.

[0073] For example, such as Figure 4As shown, the sliding drive 80 may be provided with two pins 81, both of which can be cylindrical, and the two pins 81 are spaced apart in the second direction, and both pins 81 extend along the vertical direction. The first sliding seat 71 may be integrally formed with a first plug block, and the first plug block may be provided with a first plug hole. The second sliding seat 72 may be integrally formed with a second plug block, and the second plug block may be provided with a second plug hole. The two pins 81 on the sliding drive 80 can be inserted into the first plug hole and the second plug hole respectively.

[0074] When the sliding seat assembly 70 needs to switch between the first and second positions, the two pins 81 are respectively inserted into the corresponding sockets, thereby driving the first sliding seat 71 and the second sliding seat 72 to slide synchronously. Secondly, when the sliding module 30 moves upward or downward, the pins 81 that are inserted into the first or second socket can automatically disengage or automatically complete the insertion and assembly, thus facilitating the driving connection and automatic separation of the first and second sliding seats 71 and the sliding drive 80, making it convenient to use.

[0075] In some embodiments, the drill rod 41 is provided with a liquid passage hole, which extends axially along the drill rod 41 and is used to supply liquid to the drill bit of the drill rod 41. The inlet of the liquid passage hole can be located at the bottom end of the drill rod 41, and the outlet of the liquid passage hole can be located at the top end of the drill rod 41. When the drill rod 41 is drilling, liquids such as water can be introduced into the liquid passage hole, thereby cooling the drill bit of the drill rod 41.

[0076] In some embodiments, the anchor bolt drilling rig includes a module drive, which is mounted on the drill frame 10 and connected to the sliding module 30 to drive the sliding module 30 to slide along a first direction. Specifically, the module drive can be a chain drive, a hydraulic cylinder drive, etc. This facilitates the adjustment of the vertical position of the sliding module 30.

[0077] In some embodiments, such as Figure 3 As shown, the limiting hole 73 is an elongated hole that extends along the first direction, and the two opposite holes of the limiting hole 73 in the first direction are both arc surfaces. The driving end of the limiting drive 90 can be cylindrical. Thus, the length of the limiting hole 73 can play a certain role in compensating for assembly errors and ensuring the stability of the insertion assembly of the limiting drive 90 and the limiting hole 73.

[0078] On the other hand, the arc surface design can increase the contact area between the limit drive 90 and the hole wall of the limit hole 73, thereby improving the stability of the first sliding seat 71 and the second sliding seat 72 in cooperation with the limit drive 90. It also helps to reduce the pressure effect and avoid the reaction force generated during the drilling process being applied to the limit drive 90, which could easily cause damage to the limit drive 90.

[0079] In some embodiments, the output speed of the drilling rig 40 is greater than the output speed of the pre-tensioning drilling rig 50, and the output torque of the drilling rig 40 is less than the output torque of the pre-tensioning drilling rig 50. Compared with the requirements of existing Chinese anchor bolt operations for high rotational speed and high torque of the drilling rig, the present invention achieves the separation of the construction process by setting two drilling rigs, so that high rotational speed and high torque can be applied to different drilling rigs respectively, which helps to reduce the manufacturing cost and difficulty of the drilling rig.

[0080] In some embodiments, such as Figure 4 As shown, both the sliding module 30 and the drill box base 20 are provided with guide grooves 24, which extend along the second direction and can have a circular cross-section. When the sliding module 30 is located within the slot, the guide grooves 24 on the sliding module 30 and the drill box base 20 are connected in the second direction, that is, the guide grooves 24 on the sliding module 30 and the drill box base 20 can be connected into a single through slot, thereby facilitating the switching of the first sliding seat 71 and the second sliding seat 72 on the sliding module 30 and the drill box base 20.

[0081] like Figure 3 As shown, both the first sliding seat 71 and the second sliding seat 72 are provided with guide portions 74. The guide portions 74 can be cylindrical. The guide portions 74 are slidably assembled in the guide groove 24 and are engaged and limited by the guide groove 24. That is, the width dimension of the groove opening of the guide groove 24 is smaller than the radial dimension of the guide portion 74, thereby preventing the guide portion 74 from coming out of the groove opening of the guide groove 24 and improving the structural stability of the assembly.

[0082] In some embodiments, such as Figure 4 As shown, the drill box base 20 includes a first plate 21, two second plates 22 and multiple inclined plates 23. The guide groove 24 of the drill box base 20 is provided on one side of the first plate 21 (which can be the front side). The two second plates 22 are fixed to the other side of the first plate 21 (which can be the rear side), and the two second plates 22 are arranged at intervals in the second direction. The drill frame 10 is fitted between the two second plates 22. The interval between the two second plates 22 can form the above-mentioned slot. At this time, the first plate 21 is also considered to include two independent plate parts. The two independent plate parts are respectively connected to the two second plates 22 one by one, and the slot is also located between the two independent plate parts.

[0083] An inclined plate 23 is located outside the two second plates 22 and fixed at the angle formed by the first plate 21 and the second plate 22, and the inclined plate 23 is arranged perpendicular to both the first plate 21 and the second plate 22. The inclined plate 23 can enhance the structural strength, thereby fully meeting the technological requirements of downhole construction.

[0084] In some embodiments, the clamping mechanism 60 further includes a base 61, a driver 63, and a transmission component 64. The base 61 includes a mounting plate 613, a first guard plate 611, and a second guard plate 612. The mounting plate 613 can be generally flat. During assembly, the mounting plate 613 can be arranged horizontally and fixed to the top of the anchor drilling rig. The fixing method can be bolts, snap-fit, etc.

[0085] The first protective plate 611 and the second protective plate 612 are both fixed to the top side of the mounting plate 613, and the first protective plate 611, the second protective plate 612, and the mounting plate 613 form an assembly cavity 614. For example, as Figure 5 and Figure 6 As shown, both the first protective plate 611 and the second protective plate 612 can be fixed to the top side of the mounting plate 613 by bolts. The first protective plate 611 can be located on the left side of the mounting plate 613, and the second protective plate 612 can be located on the right side of the mounting plate 613. The first protective plate 611 and the second protective plate 612 can be arranged at intervals in the left-right direction. The space between the first protective plate 611 and the second protective plate 612 can form the assembly cavity 614. In some other embodiments, the mounting plate 613, the first protective plate 611, and the second protective plate 612 can also be integrally formed.

[0086] The driver 63 is assembled in the assembly cavity 614, the transmission component 64 is connected to the driver 63, and the first clamp 621 and the second clamp 622 are both slidably assembled with the transmission component 64 so as to switch to the first mode or the second mode through the sliding assembly when the driver 63 drives the transmission component 64 to move.

[0087] For example, the actuator 63 can be linearly driven, meaning it can extend and retract along the front-to-back direction. The actuator 63 can be fixed within the assembly cavity 614 and can be mounted and fixed to the mounting plate 613 using bolts or other fasteners. The transmission component 64 can be fixed to the drive end of the actuator 63, and both the first clamp 621 and the second clamp 622 can be slidably assembled with the transmission component 64. In use, the actuator 63 can drive the transmission component 64 to move back and forth. For example, when the transmission component 64 moves forward, both the first clamp 621 and the second clamp 622 will swing inward, thereby reducing the opening angle of the first clamp 621 and the second clamp 622, allowing the clamp assembly 62 to be adjusted to a first configuration. When the transmission component 64 moves backward, both the first clamp 621 and the second clamp 622 will swing outward, thereby increasing the opening angle of the first clamp 621 and the second clamp 622, allowing the clamp assembly 62 to be adjusted to a second configuration.

[0088] The clamping mechanism 60 of this invention not only assists in straightening the anchor bolt and drill rod 41, but also allows the drill box to pass through, making switching operations convenient and improving the automation of anchor bolt support construction. Secondly, since the driver 63 is installed inside the assembly cavity 614, the mounting plate 613, the first protective plate 611, and the second protective plate 612 can shield and conceal the driver 63, thereby protecting it and preventing it from being easily damaged by falling coal gangue, thus improving its stability during use.

[0089] In some embodiments, the transmission member 64 is provided with a sliding groove, the extension direction of which is orthogonal to the direction in which the driver 63 drives the transmission member 64 to move. For example, the driver 63 can drive the transmission member 64 to reciprocate in the front-back direction, and the sliding groove can extend in the left-right direction. The first clamp 621 is provided with a first sliding pin 6213, which can be integrally formed on the first clamp 621. The second clamp 622 is provided with a second sliding pin 6223, which can be integrally formed on the second clamp 622. Both the first sliding pin 6213 and the second sliding pin 6223 are slidably assembled in the sliding groove. This simplifies the sliding assembly form of the first clamp 621, the second clamp 622 and the transmission member 64, and also ensures the structural stability and reliability of the sliding assembly.

[0090] In some embodiments, such as Figure 8 As shown, the actuator 63 is a hydraulic cylinder and includes a drive rod 631. The transmission member 64 is connected to the front end of the drive rod 631 and is arranged orthogonally to the drive rod 631. For example, the transmission member 64 can be a long plate and extend in the left-right direction, and the drive rod 631 can be a round rod and extend in the front-back direction.

[0091] like Figure 8 As shown, the slide includes a first slide 641 and a second slide 642. Both the first slide 641 and the second slide 642 can be waist-shaped. The first slide 641 and the second slide 642 are arranged at intervals in the left and right direction and both extend along the extension direction (left and right direction) of the transmission member 64. The first sliding pin 6213 is slidably assembled in the first slide 641 and can rotate relative to it in the first slide 641. The second sliding pin 6223 is slidably assembled in the second slide 642 and can rotate relative to it in the second slide 642.

[0092] Specifically, both the first sliding pin 6213 and the second sliding pin 6223 can be cylindrical, which can reduce the contact area with the slide groove and ensure smooth sliding. On the other hand, the swinging of the first clamp 621 and the second clamp 622 will cause the first sliding pin 6213 and the second sliding pin 6223 to rotate in the corresponding slide groove, thereby avoiding interference from the rotation of the sliding pin in the corresponding slide groove.

[0093] In some embodiments, the first clamp 621 is provided with a first slot 6212, the second clamp 622 is provided with a second slot 6222, the first clamp 621 is engaged in the second slot 6222, and the drive rod 631 and the drive member are engaged in the first slot 6212.

[0094] For example, such as Figure 7 As shown, the first slot 6212 can be provided in the rear half of the first clamp 621, and the first slot 6212 can penetrate the first clamp 621 in the left-right direction, with the slot opening facing rearward. Similarly, the second slot 6222 can be provided in the rear half of the second clamp 622, and the second slot 6222 can penetrate the second clamp 622 in the left-right direction, with the slot opening facing rearward.

[0095] The rear end of the first clamp 621 can be rotatably fitted into the second slot 6222, while the drive rod 631 and the drive component are both located within the first slot 6212 and the second slot 6222. This design serves two purposes: firstly, it conceals and hides the drive rod 631 and the drive component, thus providing protection; secondly, it allows the drive rod 631 and the drive component to utilize the space within the first clamp 621 and the second clamp 622, improving the compactness of the structural assembly and ensuring structural strength.

[0096] In some embodiments, the clamping mechanism 60 includes a first pin 65 and a second pin 66, which are coaxially arranged. The first clamp 621 and the second clamp 622 on one side of the first slot 6212 are rotatably connected to one of the first guard plate 611 and the second guard plate 612 via the first pin 65. The first clamp 621 and the second clamp 622 on the other side of the first slot 6212 are rotatably connected to the mounting plate 613 via the second pin 66.

[0097] For example, such as Figure 8 As shown, in the vertical direction, the portions of the first clamps 621 on both the upper and lower sides of the first slot 6212 can form first arms, and the first slot 6212 is formed between the two first arms. Similarly, the portions of the second clamps 622 on both the upper and lower sides of the second slot 6222 can form second arms, and the second slot 6222 is formed between the two second arms.

[0098] The first pin 65 can pass through the first guard plate 611, the first arm on the upper side of the first clamp 621, and the second arm on the upper side of the second clamp 622, enabling pivotal assembly of the three. The second pin 66 can pass through the mounting plate 613, the first arm on the lower side of the first clamp 621, and the second arm on the lower side of the second clamp 622, also enabling pivotal assembly of the three. This avoids interference between the pins and the driving components and driving rod 631, improving assembly convenience.

[0099] In some embodiments, such as Figure 5 As shown, the first guard plate 611 can be integrally formed with an extension 6111, which extends toward the second guard plate 612. For example, the extension 6111 can generally extend in a left-right direction and can be positioned horizontally at the top opening of the mounting cavity 614. The first pin 65 passes through the upper first arm of the first clamp 621 and the upper second arm of the second clamp 622 and is pivotally connected to the extension 6111. The extension 6111 improves the ease of installation.

[0100] In some embodiments, the included angle formed by the first clamp 621 and the second clamp 622 in the second configuration is greater than the opening angle of the first clamp 621 and the second clamp 622 in the first configuration, and in the second configuration, the transmission member 64 abuts against at least one of the bottom of the first slot 6212 and the bottom of the second slot 6222 to limit the upper limit of the opening angle of the first clamp 621 and the second clamp 622 in the second configuration.

[0101] For example, such as Figure 7 As shown, in the second configuration, the outer edge of the bottom of the second slot 6222 can abut against the front surface of the transmission component 64, thereby preventing the second clamp 622 from continuing to swing to the right, and thus limiting the effect of the first clamp 621 swinging to the left. This avoids the situation where the opening and closing angle of the first clamp 621 and the second clamp 622 is too large and it is easy to generate a dead point, thus ensuring the stability of use.

[0102] In some other embodiments, in the second configuration, the transmission member 64 can simultaneously engage with the first clamp 621 and the second clamp 622.

[0103] In some embodiments, the projection of the first clamp 621 onto the mounting plate 613 and the projection of the second clamp 622 onto the mounting plate 613 are both V-shaped, and the bends of the first clamp 621 and the second clamp 622 are arranged opposite to each other.

[0104] For example, such as Figure 5 and Figure 6 As shown, the rear half of the first clamp 621 can extend in the front-rear direction, and the front half of the first clamp 621 can generally extend in the direction from left front to right rear. The rear half of the second clamp 622 can extend in the front-rear direction, and the front half of the second clamp 622 can generally extend in the direction from right front to left rear. The assembly cavity 614 can be formed between the rear half of the first clamp 621 and the rear half of the second clamp 622. The front and rear ends of the first clamp 621 and the second clamp 622 can be fixed by bolts.

[0105] This design allows for a wide and relatively balanced distribution of fastening forces, thereby improving the overall structural stability.

[0106] In some embodiments, in a first configuration, the end face of the slot opening of the first slot 6211 and the end face of the slot opening of the second slot 6221 are attached together to form an interface 623, and the interface 623 is not perpendicular to the sliding direction of the sliding assembly and the driving direction of the driver 63.

[0107] Specifically, such as Figure 5 As shown, the interface 623 of the first clamp 621 and the second clamp 622 in the first configuration can be shown as a dashed line. The interface 623 can be arranged at an angle from right front to left rear. As a result, the direction of the force at the interface 623 and the direction of the force applied by the driver 63 to the transmission member 64 are at an angle, realizing the cross arrangement of different forces, which is conducive to interlocking and enhancing the clamping effect on the anchor rod and drill rod.

[0108] The integrated anchor-grouting automated drilling rig of this invention has the following advantages:

[0109] (1) The device of this invention is used in conjunction with a hollow anchor injection integrated anchor rod, which reduces the traditional anchor rod operation process of 6 steps (drilling - unloading the drill rod - installing the anchoring agent - installing the anchor rod and tray - mixing the anchoring agent and pre-tightening) to 4 steps (drilling - installing the anchor rod and tray - pumping the anchoring agent - pre-tightening), which simplifies the process of removing the drill rod and applying the anchoring agent, and improves the automation level and operation efficiency of the anchor rod operation;

[0110] (2) The drill rod is always fixedly connected to the drilling box, avoiding processes such as putting on and taking off the drill rod, and realizing the automation of the drilling process;

[0111] (3) The process of pump injection of anchoring agent avoids the problem of manual application of the agent roll, and improves the automation level and efficiency of anchor bolt operation.

[0112] (4) Traditional anchor bolting processes require high rotation speed and high torque from the drill box. In this invention, the construction process is split into two drill boxes. One drill box achieves high rotation speed, and the other drill box achieves high torque, which reduces the manufacturing cost and difficulty of the drill box.

[0113] (5) The design scheme of two drilling boxes, one drilling box is responsible for drilling and the other drilling box is responsible for grouting and pre-tightening, which avoids the problems of complex structure and low reliability of the integrated anchoring and grouting drilling box. The two drilling box schemes reduce the structural complexity of the drilling box and improve the reliability of the equipment by process separation.

[0114] (6) The clamping mechanism adopts a direct-push sliding mechanism (which can be regarded as the assembly of the driver 63 and the transmission component 64). It can achieve the control of the large-angle opening and closing of the left and right clamps through the small displacement sliding in the groove of the special-shaped oil cylinder, so as to meet the direct passage of the large tray and the drill box, and also play the role of straightening the drill rod in the early stage of drilling.
