Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, specifically to a correction and guidance type drilling and anchoring integrated trolley and its anchor rod propulsion and correction device. Background Technology

[0002] Anchor bolt trolleys are common construction equipment in tunnel construction. Their function is to reinforce the rock strata and support the tunnel by drilling holes and installing anchor bolts. With the development of intelligent technology, anchor bolt drilling rigs can basically complete a series of actions autonomously, such as drilling, pushing anchor bolts, blowing explosives, grouting, and low-prestress pull-out. However, certain constraints still exist in actual construction. For example, during the process of pushing anchor bolts, the cantilevered part at the front end of the anchor bolt deviates from the axis center due to its own structure and gravity, and naturally droops. This causes deviations in the end travel path, making it impossible to accurately pass through the hole-aligning device. This is especially true for anchor bolts pushed horizontally, often requiring repeated forward and backward movements to push the anchor bolt, and sometimes even manual assistance to help the anchor bolt pass through the hole-aligning device. This results in excessively long anchor bolt construction time, a significant decrease in construction efficiency, increased construction safety risks, and serious impacts on the construction period.

[0003] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0004] The purpose of this invention is to provide a correction-guided drilling and anchoring integrated trolley and its anchor bolt propulsion correction device to solve the problems of anchor bolts deviating from the axis center and the end travel path deviation in existing equipment during the anchor bolt pushing process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anchor rod pushing and correcting device for a drilling and anchoring integrated trolley with a correction and guidance type is provided. The anchor rod pushing and correcting device is set on the pushing path of the anchor rod in the drilling and anchoring integrated trolley and includes two inner cone guide halves and two opening and closing support arms.

[0007] The two inner conical guide halves are symmetrically arranged on the left and right, and are joined together to form a guide tube. A guide hole is provided on the central axis of the guide tube. The inner diameter of the guide hole gradually increases from front to back, and a conical surface is formed on the inner wall of the large circular opening side at the rear end. When the anchor rod is pushed from back to front, it is gradually pushed from the conical surface to the small circular opening side at the front end. When it passes through the guide hole, the pushing direction is corrected.

[0008] The opening and closing support arm is a support component of the inner conical guide half. The top of the opening and closing support arm is fixedly connected to the outer wall of the inner conical guide half, and the two opening and closing support arms are arranged symmetrically from left to right.

[0009] Furthermore, a transverse connecting rod is provided between the lower parts of the two opening and closing support arms, and the two ends of the connecting rod are hinged to the opening and closing support arms by hinge bolts.

[0010] Furthermore, a transverse telescopic cylinder is provided between the bottoms of the two opening and closing support arms. The telescopic cylinder is located below the connecting rod, and both ends of the telescopic cylinder are hinged to the opening and closing support arm through cylinder hinge bolts.

[0011] When the telescopic cylinder extends or retracts laterally, the opening and closing support arm rotates around the hinge bolt, causing the guide tube to open or close.

[0012] Furthermore, the opening and closing support arm is a bent structure, divided into an upper part, a middle part and a lower part. The upper part is located between the inner cone guide half and the hinge bolt, the middle part is located at the hinge bolt, and the lower part is located between the hinge bolt and the hydraulic cylinder hinge bolt.

[0013] Furthermore, the guide hole includes a straight hole section and an enlarged hole section from front to back. The diameter of the straight hole section is the same from front to back, the diameter of the front end of the enlarged hole section is the same as the diameter of the straight hole section, and the diameter of the enlarged hole section gradually increases from front to back.

[0014] On the other hand, a correction and guidance type drilling and anchoring integrated trolley is provided, the drilling and anchoring integrated trolley includes a chassis, an anchor bolt working arm, an anchor bolt machine head and the anchor bolt propulsion and correction device;

[0015] The fixed end of the anchor bolt working arm is located at the top front end of the chassis, the anchor bolt head is located at the working end of the anchor bolt working arm, and the anchor bolt propulsion and correction device is located at the front end of the anchor bolt head.

[0016] Furthermore, the anchor bolt working arm includes a telescopic boom, a propulsion beam, and a propulsion cylinder, with the propulsion cylinder located at the front end of the telescopic boom and the propulsion beam located at the front end of the propulsion cylinder;

[0017] The anchor bolt head is installed on the propulsion beam.

[0018] Furthermore, the anchor bolt advancing and correcting device is fixed to one end of the advancing beam near the working face by hinge bolts.

[0019] Furthermore, the drilling and anchoring trolley also includes an anchor bolt magazine, a front manipulator, and a rear manipulator, all of which are installed on the lateral side of the anchor bolt working arm;

[0020] The front and rear robotic arms are arranged one after the other to synchronously grab anchor bolts stored in the anchor bolt library and transfer them to the anchor bolt machine head.

[0021] Furthermore, the anchor bolt head is mounted on the head support plate on the propulsion beam.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides a guide-type drilling and anchoring integrated trolley and its anchor rod advancing and correcting device. The anchor rod advancing and correcting device has a guide hole with a diameter that decreases from large to small. The large circular opening side of the guide hole has a conical surface. During the anchor rod advancing process, when its position and direction deviate due to gravity, the anchor rod can slowly slide from the conical surface on the large circular opening side of the guide hole of the anchor rod advancing and correcting device towards the center to achieve centering. This allows the anchor rod to pass through the guide hole until it reaches the anchor rod hole on the working face, quickly completing the alignment of the anchor rod and the anchor rod hole. This ensures the stability and accuracy of the anchor rod advancing process, significantly improves the construction speed and quality, avoids manual intervention, and ensures construction safety.

[0037] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0038] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] In a specific implementation, Figure 5 The direction from left to right is defined as the vertical, and the direction perpendicular to it is defined as the horizontal. Figure 5 The left side of the text is defined as the front end. Figure 5 The right side of the diagram defines the backend, and other attached diagrams are consistent with this.

[0041] Currently, the drilling and anchoring rigs commonly used in tunnel construction are multifunctional and easy to operate. They can basically complete a series of actions autonomously, such as drilling, pushing anchor bolts, blowing explosives, grouting, and low-prestress pull-out. Figure 1 Generally, it includes a mobile chassis 1, on which a cab 2 is mounted, and multiple working arms carrying different functional construction components on the front top of the chassis 1. For example... Figure 2 In this embodiment, the working platform 3 is mounted on the right front side of the chassis 1 via the platform working arm 5, and the rock drilling mechanism and the anchor bolt head 6 are mounted on the left front side via the anchor bolt working arm 4. Additionally, it may also be equipped with an anchoring agent blowing device, a grouting cartridge blowing device, a grouting head, etc.

[0042] Based on the existing equipment structure, this invention integrates an anchor bolt propulsion and correction device 10 into the drilling and anchoring trolley, designing a correction-guided drilling and anchoring trolley to overcome the problem that existing equipment cannot correct anchor bolts with deviations in their travel path. It should be noted that this invention does not modify other components such as the chassis or working arm; these components can all adopt existing structural forms.

[0043] like Figures 3-6 The anchor bolt pushing and correction device 10 is installed on the pushing path of the anchor bolt 13 in the drilling and anchoring integrated trolley, and includes two inner conical guide halves 1009 and two opening and closing support arms 1001. The two inner conical guide halves 1009 are symmetrically arranged on both sides and can be joined together to form a guide tube 1005. A guide hole 1008 is provided on the central axis of the guide tube 1005. The inner diameter of the guide hole 1008 gradually increases from front to back, forming a smooth conical surface on the inner wall of the large circular opening side at the rear end. Specifically, the guide hole 1008 includes a straight hole section and an enlarged hole section from front to back. The diameter of the straight hole section is the same from front to back, and the diameter of the front end of the enlarged hole section is the same as the diameter of the straight hole section, while the diameter of the enlarged hole section gradually increases from front to back.

[0044] like Figure 5 and Figure 6 When the anchor rod 13 is pushed from back to front, the guide hole 1008 is directly facing the anchor rod hole 12 on the working face 11. The anchor rod 13 is first pushed forward from the conical surface, and then guided into the straight hole section in the hole expansion section. When it reaches the small round opening side at the front end, the anchor rod 13 passes through the guide hole 1008, and the pushing direction is corrected so that it can be directly inserted into the anchor rod hole 12.

[0045] The opening and closing support arm 1001 serves as a support for the inner conical guide half 1009. The top of the opening and closing support arm 1001 is fixedly connected to the outer wall of the inner conical guide half 1009, and can be a single integrated structure. The two opening and closing support arms 1001 are arranged symmetrically from left to right, with their bottoms angled outwards. A transverse connecting rod 1002 is provided between the lower parts of the two opening and closing support arms 1001, and both ends of the connecting rod 1002 are hinged to the opening and closing support arm 1001 via hinge bolts 1006. A transverse telescopic cylinder 1003 is also provided between the bottoms of the two opening and closing support arms 1001. The telescopic cylinder 1003 is located below the connecting rod 1002, and both ends of the telescopic cylinder 1003 are hinged to the opening and closing support arm 1001 via cylinder hinge bolts 1004. Specifically, the opening and closing support arm 1001 is a bent structure, divided into an upper part, a middle part and a lower part. The upper part is located between the inner cone guide half 1009 and the hinge bolt 1006, the middle part is located at the hinge bolt 1006, and the lower part is located between the hinge bolt 1006 and the hydraulic cylinder hinge bolt 1004.

[0046] When the telescopic cylinder 1003 extends or retracts laterally, the opening / closing support arm 1001 rotates around the hinge bolt 1006, causing the guide tube 1005 to open or close. Specifically, as shown... Figure 4 When the telescopic cylinder 1003 shortens, the distance between the two hinge bolts 1006 remains unchanged, and the opening and closing support arm 1001 rotates around the hinge bolt 1006. The left opening and closing support arm 1001 rotates counterclockwise and its top moves to the left, while the right opening and closing support arm 1001 rotates clockwise and its top moves to the right. At this time, the guide tube 1005 opens. Conversely, when the telescopic cylinder 1003 extends, the action is reversed. The left opening and closing support arm 1001 rotates clockwise and its top moves to the right, while the right opening and closing support arm 1001 rotates counterclockwise and its top moves to the left, and the guide tube 1005 closes.

[0047] This utility model also provides a guide-type drilling and anchoring integrated trolley, which includes a chassis 1 that can travel and carry a cab 2, an anchor bolt working arm 4, an anchor bolt head 6, and the aforementioned anchor bolt propulsion and correction device 10. The fixed end of the anchor bolt working arm 4 is located at the top front end of the chassis 1. The anchor bolt head 6 is an existing device and is located at the working end of the anchor bolt working arm 4. The anchor bolt propulsion and correction device 10 is located at the front end of the anchor bolt head 6. In addition, the anchor bolt working arm 4 is also equipped with rock drilling components, etc., all of which adopt existing structures and are arranged horizontally side by side with the anchor bolt head 6, allowing for switchable operation.

[0048] like Figure 1The anchor bolt working arm 4 includes a telescopic boom 401, a propulsion beam 402, and a propulsion cylinder 403. The propulsion cylinder 403 is located at the front end of the telescopic boom 401, and the propulsion beam 402 is located at the front end of the propulsion cylinder 403. The anchor bolt head 6 is mounted on the propulsion beam 402. The propulsion cylinder 403 uses existing equipment, and its main operation is to push the anchor bolt head 6 to push the anchor bolt 13 into the anchor bolt hole 12. Additionally, the anchor bolt head 6 can drive the anchor bolt 13 to rotate, stirring the anchoring agent or grout cartridge previously fed into the anchor bolt hole 12. After the grout cartridge solidifies, prestressed pulling can be achieved, locking the anchor bolt nut. The grouting head on the anchor bolt head 6 can be flipped down to the grouting position and connected to the tail of the anchor bolt 13. Then, the prepared grout enters from inside the anchor bolt 13, passes through the grouting port, and fills the gap between the hole wall and the anchor bolt 13.

[0049] Anchor bolt pushing and correction device 10 is installed on the pushing beam 402. The anchor bolt pushing and correction device 10 is fixed to the end of the pushing beam 402 near the working face with hinge bolts, that is, on the pushing guide beam 1007 at the front end of the pushing beam 402. The anchor bolt machine head 6 is installed on the machine head support plate on the pushing beam 402. When the anchor bolt machine head 6 moves forward along the pushing beam 402 under the push of the pushing cylinder 403, it can push the anchor bolt 13 into the anchor bolt pushing and correction device 10. After correction, the anchor bolt 13 is accurately pushed into the drilled anchor bolt hole 12.

[0050] In addition, the drilling and anchoring trolley also includes an anchor bolt magazine 9, a front robotic arm 7, and a rear robotic arm 8, all installed on one side of the anchor bolt working arm 4. The front robotic arm 7 and the rear robotic arm 8 are arranged one behind the other, synchronously grabbing the anchor bolts 13 stored in the anchor bolt magazine 9, flipping them, and transferring them to the anchor bolt machine head 6 for subsequent pushing. In addition to grabbing and pushing the anchor bolts 13 together with the front robotic arm 7, the rear robotic arm 8 can also play a stabilizing and guiding role for the anchor bolts 13 during the pushing process.

[0051] Anchor bolt magazine 9 is used to store anchor bolts 13 and can rotate automatically. Specifically, anchor bolt magazine 9 includes a bracket 901, a main shaft 902, a bolt storage tray 903, a spring clip 904, and a drive device 905. One end of the main shaft 902 is connected to the drive device 905, which is equipped with a hydraulic motor. The hydraulic motor rotates according to a programmed deflection angle, driving the main shaft 902 to rotate and grasp the anchor bolts 13 step by step. The bracket 901 supports the shaft of the main shaft 902, which is inserted into the center of the bolt storage tray 903, with the anchor bolts 13 inserted through the edge of the tray 903. The spring clip 904 is installed on the bolt storage tray 903 to fix the anchor bolts 13. The bolt storage tray 903 can be installed to store anchor bolts of different lengths according to construction requirements.

[0052] The anchor bolt pushing and correction device 10 of this utility model can quickly correct and stably push the anchor bolt 13. Its guide hole 1008 has a smooth conical surface, and the arc curve is smooth and without jamming. It can not only avoid the positional deviation of the anchor bolt 13 affected by its own weight, but also eliminate the deviation caused by the manufacturing of the anchor bolt trolley itself, increase the allowable error range of the anchor bolt 132 entering the hole, ensure the hit rate of pushing the anchor bolt 13 into the hole, and achieve 360-degree all-round correction guidance. When the position and direction of the anchor bolt 13 deviate during the pushing process, the conical surface on the large circular opening side of the anchor bolt pushing and correction device 10 slowly slides towards the center as it is pushed, so that the anchor bolt 13 passes through the anchor bolt pushing and correction device 10, and quickly completes the axial alignment of the anchor bolt 13 and the anchor bolt hole 12. The construction efficiency and construction accuracy are significantly improved.

[0053] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
