Through integrated design, the equipment realizes the continuous operation of drilling, installing anchor rods or anchor cables, grouting and curing, and improves construction efficiency and project quality.

[0003] Existing drilling, anchoring and injection machines usually use anchor clamps to push anchors during construction. However, there is a certain distance between the anchor clamp and the end of the anchor, usually about 1.2 meters. This distance causes the anchor to deviate due to gravity during the pushing process, which in turn causes the anchor head and the drill hole position to deviate easily. This deviation not only increases the difficulty of construction operations, but also significantly prolongs the construction time. Construction personnel need to frequently swing the anchor head to correct the anchor position, which not only increases the complexity of operation, but may also affect the construction quality. Especially under some complex geological conditions, the deviation problem of anchors is more prominent, resulting in low efficiency of anchor construction, extended construction period and increased costs.

Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Existing drilling, anchoring and injection machines usually use anchor clamps to push anchors during construction. However, there is a certain distance between the anchor clamp and the end of the anchor, usually about 1.2 meters. This distance causes the anchor to deviate due to gravity during the pushing process, which in turn causes the anchor head and the drill hole position to deviate easily. This deviation not only increases the difficulty of construction operations, but also significantly prolongs the construction time. Construction personnel need to frequently swing the anchor head to correct the anchor position, which not only increases the complexity of operation, but may also affect the construction quality. Especially under some complex geological conditions, the deviation problem of anchors is more prominent, resulting in low efficiency of anchor construction, extended construction period and increased costs.

[0033] In order to solve this technical problem, the present invention proposes an anchor head deviation correction device for a tunnel drilling, anchoring and injection molding machine.

[0034] See also Figure 1 and Figure 2 In one embodiment of the present invention, the bolt head correction device for the tunnel drilling, anchoring and grouting machine includes a mounting seat 100, a correction mechanism 200, a locking mechanism 300 and a driving mechanism. The correction component 21 is hinged to the mounting seat 100, and the correction mechanism 200 is formed with a correction space 201 for accommodating the bolt head, and the correction space 201 extends along the axial direction of the bolt head; the locking mechanism 300 is rotatably mounted on the mounting seat 100, and the locking mechanism 300 and the correction mechanism 200 are arranged at intervals; the driving mechanism is mounted on the mounting seat 100, and the output shaft of the driving mechanism is connected to the locking mechanism 300. The driving mechanism is used to drive the locking mechanism 300 to rotate relative to the correction mechanism 200 between the locking position and the release position, so that the locking mechanism 300 is pressed against or away from the correction mechanism 200, so as to limit the bolt head in the correction space 201 or release the bolt head accordingly.

[0035] Specifically, the mounting seat 100 is used as the basic support structure of the entire deviation correction device, and is used to install the deviation correction mechanism 200, the locking mechanism 300 and the driving mechanism, so that the entire device remains stable during operation. The deviation correction mechanism 200 is hinged to the mounting seat 100, and forms a deviation correction space 201 for accommodating the anchor head. The deviation correction space 201 extends along the axial direction of the anchor head, and can effectively guide and position the anchor head. When the deviation between the anchor head and the target hole position is within 5 cm, the deviation correction mechanism 200 contacts the anchor head through the inner wall corresponding to the deviation correction space 201 to guide the anchor head, adjust its position and angle, and accurately align the anchor head with the center position of the drilling hole to ensure the smooth progress of the rod feeding process. The locking mechanism 300 is rotatably mounted on the mounting seat 100 and is spaced apart from the deviation correction mechanism 200. The locking mechanism 300 is connected to the driving mechanism, and rotates between the locking position and the release position relative to the deviation correction mechanism 200 under the action of the driving mechanism. When the locking mechanism 300 is in the locking position, it can press against the deviation correction mechanism 200, so that the anchor head can be slidably clamped and limited in the deviation correction space 201 to prevent it from deflecting during the pushing process; when the locking mechanism 300 is in the release position, the anchor head can be loosened to facilitate subsequent operations. The driving mechanism is installed on the mounting seat 100, and its output shaft is connected to the locking mechanism 300. The driving mechanism realizes the limiting or loosening operation of the anchor head by controlling the rotation of the locking mechanism 300. The driving mechanism can be a motor, a hydraulic cylinder or other suitable driving device in the prior art, and through its precise control, the rapid positioning and deviation correction of the anchor head can be realized. The deviation correction space 201 formed by the deviation correction mechanism 200 can accurately align the anchor head with the center position of the drill hole by adjusting its position and angle when the deviation of the anchor head does not exceed 5 cm, effectively reducing the deviation phenomenon. The cooperation between the locking mechanism 300 and the driving mechanism makes the limiting and loosening operation of the anchor head simpler and faster, reducing the operation steps and time of the construction personnel.

[0036] More specifically, the main function of the locking mechanism 300 is to ensure that the correction space 201 formed by the correction mechanism 200 remains stable by pressing against the correction mechanism 200 when the anchor head is limited. This pressing action prevents the correction space 201 from being expanded by the anchor head when guiding the anchor head, thereby ensuring that the shape and size of the correction space 201 remain unchanged during the pushing process of the anchor head. The locking mechanism 300 includes one or more adjustable locking components, which can rotate between a locking position and a release position relative to the correction mechanism 200 under the action of a driving mechanism. When the locking component is in the locking position, the locking component forms a stable clamping force by pressing against the correction mechanism 200, limiting the anchor head in the correction space 201; when the locking component is in the release position, the clamping component loosens the correction mechanism 200, facilitating the removal or adjustment of the anchor head.

[0037] In the technical solution provided by the present invention, compared with the prior art, the frequent mechanical adjustment and swinging operation processes are reduced through the cooperation of the correction mechanism 200, the locking mechanism 300 and the driving mechanism, thereby reducing the wear of the equipment, extending the service life of the equipment, and reducing the maintenance cost; during the anchor construction process, the correction mechanism 200 is used to accurately guide and position the construction process of the anchor head, ensuring that the anchor head can accurately enter the target hole position, improving the quality and safety of the anchor construction, and using the locking mechanism 300 and the driving mechanism to simplify the limiting and loosening operation steps of the anchor head, solving the problem of anchor head offset, significantly improving construction efficiency, reducing operation time, reducing the operation difficulty of construction personnel, reducing construction risks caused by complex operations, and significantly improving the construction efficiency of anchor construction.

[0038] As an optional implementation of this embodiment, by adjusting the locking force of the locking mechanism 300, the pressure applied by the locking mechanism 300 to the correcting mechanism 200 can be changed, so that the correcting space 201 formed by the correcting mechanism 200 can be expanded or reduced within a certain range. Specifically, when it is necessary to adapt to an anchor rod with a larger diameter, the locking force can be reduced to appropriately expand the correcting space 201; when it is necessary to adapt to an anchor rod with a smaller diameter, the locking force can be increased to reduce the correcting space 201 to adapt to anchor rods of different diameters, so that the correcting space 201 can be applied to more types of anchor rods, thereby improving the adaptability of the device. In addition, since the correcting space 201 can be adjusted, the need for frequent replacement of equipment due to changes in the diameter of the anchor rod is reduced, thereby reducing operating time and cost.

[0039] As another optional implementation of this embodiment, the deviation correction space 201 is cylindrical and extends along the axial direction of the anchor head. The diameter of the inner part of the cylindrical structure is slightly larger than the diameter of the anchor head to provide sufficient guiding space, and the cylindrical structure is simple in design, easy to manufacture and install, and reduces production and maintenance costs.

[0040] As another optional implementation manner of the present embodiment, the correction space 201 is trumpet-shaped, and the rod entry opening of the correction space 201 is larger than the rod exit opening of the correction space 201. The larger rod entry opening of the trumpet-shaped correction space 201 can more easily accommodate the offset anchor head, so that the anchor head can enter the correction space 201 more smoothly and is less likely to get stuck or deviate when it initially enters the correction space 201. The smaller rod exit opening of the trumpet-shaped correction space 201 helps to gradually guide the anchor head into the correct position. As the anchor head moves forward, it is gradually guided to the center position, thereby achieving precise positioning.

[0041] Please continue reading Figure 1 and Figure 2There are many forms of implementation of the correction mechanism 200. In an embodiment of the present invention, the correction mechanism 200 includes two correction components 21, which are arranged at intervals along the radial direction of the anchor head. The two correction components 21 are hinged to the installation. The two correction components 21 enclose a correction space 201. The two correction components 21 can be close to or away from each other to correspondingly reduce or expand the correction space 201. The correction component 21 can rotate or swing relative to the mounting seat 100, so as to adjust and position the anchor head. The hinge structure between the correction component 21 and the mounting seat 100 allows the correction component 21 to adjust the angle within a certain range, so that the correction component 21 can be adjusted accordingly according to the offset of the anchor head to ensure that the anchor head can be accurately guided to the center of the drill hole, effectively reducing the construction error caused by the offset. The two correction components 21 are matched through their respective shapes and positions to enclose a correction space 201 for accommodating the anchor head. The deviation correction space 201 extends along the axial direction of the anchor head, and can effectively guide and position the anchor head. The two deviation correction components 21 can be moved closer or farther away from each other, thereby correspondingly reducing or expanding the deviation correction space 201 to accommodate anchors of different diameters or different degrees of deviation problems, and increasing the adaptability of the device so that it can be applied to anchors of various specifications.

[0042] It should be understood that the operation of moving the two deviation-correcting components 21 closer to each other or farther away from each other can be achieved through a manual adjustment mechanism or an automatic adjustment mechanism. The manual adjustment mechanism can be a threaded adjustment mechanism, a lever adjustment mechanism, etc.; the automatic adjustment mechanism can be an electric push rod, a hydraulic cylinder, etc., and the precise adjustment of the deviation-correcting components 21 can be achieved by controlling the motor or the hydraulic system. Obviously, when the two deviation-correcting components 21 are brought closer to each other, it can also be achieved through the locking mechanism 300.

[0043] See also Figure 3Specifically, in an embodiment of the present invention, the deviation correction component 21 includes a connecting rod 210 and a deviation correction structure 220, the connecting rod 210 is hinged to the mounting seat 100, the deviation correction structure 220 is installed at the end of the connecting rod 210, the deviation correction structures 220 of the two deviation correction components 21 are combined to form a deviation correction space 201, the locking mechanism 300 and the connecting rod 210 are arranged at intervals along the radial direction of the anchor head, and the driving mechanism is used to drive the locking mechanism 300 to rotate between the locking position and the release position relative to the connecting rod 210, so that the locking mechanism 300 is pressed against or away from the connecting rod 210, so as to limit the anchor head in the deviation correction space 201 or release the anchor head accordingly. The connecting rod 210 is hinged to the mounting seat 100, and one end thereof is connected to the deviation correction structure 220. The hinged structure allows the connecting rod 210 to rotate or swing within a certain range, so that the deviation correction structure 220 can be adjusted in position according to demand. The length and angle of the connecting rod 210 can be selected according to different sizes and types of anchor rods, and the correction structures 220 of the two correction components 21 together form a correction space 201 for accommodating and guiding the anchor rod head. The shape and size of the correction structure 220 can be selected according to the specifications of the anchor rod head to ensure the best guiding and positioning effect for the anchor rod.

[0044] See also Figure 5 More specifically, in an embodiment of the present invention, the correction structure 220 includes a correction head 221 and a connection seat 222, one end of the connection seat 222 is connected to the correction head 221, and the other end of the connection seat 222 is formed with a socket 202, one end of the connecting rod 210 extends into the socket 202 and is detachably connected to the connection seat 222; the correction heads 221 of the two correction components 21 are enclosed to form a correction space 201. The shape and size of the correction head 221 are designed to be able to cooperate with the anchor head to guide and position the anchor head. The correction head 221 has one or more guide surfaces, which can contact the surface of the anchor head, thereby providing a guiding effect when the anchor head enters the correction space 201, ensuring the stability of the anchor head during the pushing process and reducing the deviation phenomenon. One end of the connection seat 222 is connected to the correction head 221, and the other end is formed with a socket 202. The design of the socket 202 allows one end of the connecting rod 210 to be inserted and detachably connected thereto. This detachable connection method increases the flexibility and maintainability of the device, making it easy to replace or adjust the correcting head 221 and the connecting seat 222 when necessary, making the replacement and adjustment of the correcting head 221 easier and quicker, and reducing the operating steps and time of construction personnel.

[0045] It should be understood that one end of the connecting rod 210 extends into the socket 202 and is detachably connected to the connecting seat 222 so that the correction head 221 can be replaced as needed to adapt to anchor rods of different specifications and types, thereby improving the versatility and adaptability of the device. In addition, the worn correction head 221 can be replaced in time to ensure that the device always maintains a good correction effect during use and improves construction accuracy and quality.

[0046] As an optional implementation of this embodiment, the connecting rod 210 is connected to the connecting seat 222 by threads, the socket 202 of the connecting seat 222 is designed with threads inside, one end of the connecting rod 210 is threadedly matched with the socket 202, and fastening and disassembly are achieved by rotating the connecting rod 210. When the deflection correction head 221 needs to be replaced, it is only necessary to rotate the connecting rod 210, remove it from the socket 202, and replace it with a new deflection correction head 221.

[0047] As another optional implementation of this embodiment, the connecting rod 210 is connected to the connecting seat 222 by a snap-fit ​​connection, and a snap-fit ​​structure is designed inside the socket 202 of the connecting seat 222. One end of the connecting rod 210 is snap-fitted with the socket 202, and quick connection and disassembly are achieved by pressing or pulling the snap-fit ​​device. When the deflection correction head 221 needs to be replaced, it is only necessary to press the snap-fit ​​device to release the connecting rod 210 and replace the new deflection correction head 221.

[0048] As another optional implementation of this embodiment, the connecting rod 210 is connected to the connecting seat 222 by a pin, the socket 202 of the connecting seat 222 is designed with a pin hole, and one end of the connecting rod 210 is provided with a corresponding pin hole, and the connection and disassembly are achieved by inserting the pin. When the deflection correction head 221 needs to be replaced, it is only necessary to pull out the pin, separate the connecting rod 210 and the connecting seat 222, and replace the new deflection correction head 221.

[0049] See also Figure 4 In an embodiment of the present invention, the connecting rod 210 includes an arc segment 211, a transition segment 212 and a connecting segment 213. The arc segment 211 arches along the radial direction of the anchor head in a direction away from the locking mechanism 300. The connecting segment 213 extends into the socket 202 and is connected to the connecting seat 222. The arc segment 211 and the connecting segment 213 are connected through the transition segment 212.

[0050] Specifically, the transition section 212 is hinged to the mounting seat 100, and the arc section 211 is used to receive the clamping force of the locking mechanism 300, that is, the driving mechanism is used to drive the locking mechanism 300 to rotate relative to the arc section 211 between the locking position and the release position, so that the locking mechanism 300 is pressed against or away from the arc section 211, so that the connecting section 213 can correspondingly drive the connecting seat 222 and the correction head 221 to approach or move away from the anchor head, so as to correspondingly limit the anchor head in the correction space 201 or release the anchor head.

[0051] More specifically, the arc segment 211 is used to receive the clamping force of the locking mechanism 300 and transmit the force to the connecting segment 213. The arc design of the arc segment 211 can absorb and disperse the locking force, so that the connecting segment 213 connected thereto can achieve a better locking effect and a larger displacement range, thereby expanding the clamping effect. The transition segment 212 connects the arc segment 211 and the connecting segment 213, and is a relatively short straight segment or arc segment, which is used to smoothly transition between two segments of different shapes and functions. The transition segment 212 is hinged to the mounting seat 100, so that the connecting rod 210 can rotate or swing relative to the mounting seat 100, thereby realizing flexible adjustment of the connecting rod 210 so that the angle can be adjusted according to the force applied by the locking mechanism 300.

[0052] Please continue reading Figure 4 There are many forms of implementing the locking mechanism 300. In an embodiment of the present invention, the locking mechanism 300 includes a rotating shaft 310 and a cam 320. The rotating shaft 310 extends along the axial direction of the anchor head. The rotating shaft 310 is rotatably mounted on the mounting seat 100. The cam 320 is sleeved on the rotating shaft 310. The cam 320 and the correcting mechanism 200 are arranged at intervals along the radial direction of the anchor head. The output shaft of the driving mechanism is connected to the rotating shaft 310. The driving mechanism is used to drive the rotating shaft 310 to drive the cam 320 to rotate relative to the correcting mechanism 200 between the locking position and the releasing position, so that the cam 320 is pressed against or away from the correcting mechanism 200, so as to limit the anchor head in the correcting space 201 or release the anchor head accordingly.

[0053] Specifically, when the driving mechanism starts and drives the rotating shaft 310 to rotate, the rotating shaft 310 drives the cam 320 to rotate to a locking position relative to the correcting mechanism 200. In the locking position, the outer surface of the cam 320 is in close contact with the correcting mechanism 200, exerting a certain pressure to limit the anchor head in the correcting space 201. At this time, the correcting mechanism 200 and the cam 320 work together to ensure that the anchor head will not deviate during the pushing process. When the anchor head needs to be loosened, the driving mechanism drives the rotating shaft 310 to rotate in the reverse direction, so that the cam 320 rotates to a release position relative to the correcting mechanism 200. In the release position, the outer surface of the cam 320 is out of contact with the correcting mechanism 200, releasing the limiting operation on the anchor head, thereby facilitating the removal or adjustment of the anchor head.

[0054] It should be noted that the cam 320 has a thickness along the extension direction of the anchor bolt head that is compatible with the deviation correction mechanism 200. The cam 320 may be an eccentric linear roller follower disc cam 320 mechanism in the prior art.

[0055] In an embodiment of the present invention, the correction mechanism 200 is connected to the wear-resistant component 400, and the wear-resistant component 400 is sleeved in the correction space 201. Specifically, the correction mechanism 200 and the wear-resistant component 400 are connected together by an appropriate connection method (such as bolt connection, welding or other suitable fixing methods). This connection method ensures that the wear-resistant component 400 can be firmly fixed on the correction mechanism 200, thereby forming a wear-resistant protective layer in the correction space 201. The wear-resistant component 400 is usually made of wear-resistant materials, such as high-hardness alloys or other materials with good wear resistance. The wear-resistant component 400 is sleeved in the correction space 201, and its shape and size match the correction space 201 to ensure that the wear-resistant component 400 can effectively protect the correction mechanism 200 from wear during the pushing process of the anchor head. The main function of the wear-resistant component 400 is to reduce the friction and wear between the correction mechanism 200 and the anchor head through its wear-resistant material characteristics during the pushing process of the anchor head. This protective effect prolongs the service life of the correction mechanism 200 and reduces the frequency of equipment maintenance and replacement due to wear.

[0056] Please continue reading Figure 3 More specifically, in an embodiment of the present invention, the wear-resistant assembly 400 includes an ear plate 410 and a wear-resistant plate 420. The ear plate 410 extends radially of the anchor head, and the wear-resistant plate 420 extends axially of the anchor head. The ear plate 410 is connected to one end of the wear-resistant plate 420. The ear plate 410 is detachably connected to the deviation correction mechanism 200, and the wear-resistant plate 420 is sleeved in the deviation correction space 201. The ear plate 410 extends radially of the anchor head, that is, the ear plate 410 extends radially outward from the inner wall of the deviation correction mechanism 200 to form a support structure for fixing the wear-resistant plate 420. The ear plate 410 is usually made of high-strength, corrosion-resistant materials, such as alloy steel, stainless steel, etc., to ensure sufficient strength and durability during use. The shape of the ear plate 410 can be designed according to the specific structure of the deviation correction mechanism 200 to ensure a stable connection. The wear-resistant plate 420 extends along the axial direction of the anchor head, that is, the wear-resistant plate 420 extends from the position of the ear plate 410 to the axial direction of the anchor head, forming a wear-resistant layer covering the inner surface of the correction space 201. The wear-resistant plate 420 is usually made of a high-hardness, wear-resistant material, such as cemented carbide, etc., to ensure that friction and wear are effectively reduced during the pushing process of the anchor head. The shape and size of the wear-resistant plate 420 match the correction space 201 to ensure that it is tightly mounted in the correction space 201. The ear plate 410 is detachably connected to the correction mechanism 200 by bolts, snaps or other suitable connection methods. This design allows the wear-resistant component 400 to be easily disassembled and replaced, which is convenient for maintenance and repair. The ear plate 410 is usually connected to the edge or inner wall of the correction mechanism 200 to ensure that the wear-resistant plate 420 can be firmly mounted in the correction space 201.

[0057] In the embodiment of the present invention, the inner diameter of the deviation correction space 201 is gradually reduced from the mounting seat 100 toward a direction away from the mounting seat 100 along the axial direction of the anchor head.

[0058] Specifically, the correction space 201 is formed by the correction mechanism 200, and the inner diameter of the correction space 201 starts from the mounting seat 100 and gradually decreases along the axial direction of the anchor head in the direction away from the mounting seat 100. This means that during the pushing process of the anchor head, the anchor head will be gradually guided and restricted by the inner wall of the correction space 201, so as to gradually correct its deviation. The inner wall of the correction mechanism 200 is in a tapered shape, and this tapered design can be a single taper or a combination of multiple sections with different tapers. The inner wall surface of the correction mechanism 200 can be smoothed to reduce the friction resistance during the pushing process of the anchor head and further improve the pushing efficiency. The tapered correction space 201 design allows the anchor head to be gradually guided and restricted by the inner wall during the pushing process, thereby effectively correcting the deviation of the anchor head. Compared with directly using a correction space 201 of fixed size, the tapered design can correct the deviation of the anchor head more smoothly and reduce impact and wear. The tapered design enables the anchor head to gradually approach and eventually reach the ideal center position during the gradual deviation correction process, thereby improving the positioning accuracy of the anchor head.

[0059] In the embodiment of the present invention, the mounting seat 100 is connected to the end of the advancing beam 500, and the advancing beam 500 extends along the axial direction of the bolt head.

[0060] It should be noted that the propulsion beam is a prior art.

[0061] As an optional implementation of this embodiment, the mounting seat 100 is the end of the propulsion beam 500, so as not to change the overall structure and operation method of the anchoring and injection equipment in the prior art. Through the anchor head correction device, the success rate and efficiency of the rod delivery are improved, the anchor construction efficiency is improved, and the tunnel construction time is shortened, the construction progress is accelerated, and the overall construction efficiency is improved.

[0062] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
