It has an extremely low failure rate, is light in weight and easy to operate. It can achieve high-speed and high-quality drilling work in roadways with various rock hardnesses of f≤10. Using it in roadways with compressed air can save energy and increase efficiency. It is an essential equipment for users in roadways without compressed air pipelines. It can be used in conjunction with a tunnel boring machine in a fully mechanized tunnel.

[0003] In order to realize the independent rotation of the two arms, the existing double-arm hydraulic anchor drilling rig is equipped with an independent hydraulic motor and control system for each drill arm, which can adjust the drilling angle and rotation direction respectively.

The complex structure may lead to an increased failure rate and a prolonged maintenance cycle. The independent hydraulic motor and control system require more components and technical support, which will significantly increase the manufacturing and maintenance costs of the equipment. The initial investment and subsequent maintenance costs of the equipment are high. The design of independent rotation of the two arms increases the size and weight of the drilling rig, and may require more operating space, which limits its use in narrow working environments. In response to the above problems, a crawler-type double-arm hydraulic anchor drilling rig is proposed to solve them. Summary of the Invention

[0018] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] Example 1 Reference Figure 1 - Figure 9As shown, a crawler-type double-arm hydraulic anchor drilling vehicle comprises a mounting shell 1, and a crawler walking part 2 is fixedly mounted on the bottom of the mounting shell 1. The crawler design has a large ground pressure ratio, can stably walk on soft, muddy or rugged roadways or tunnel bottoms, has strong passing performance, is not easy to slip and sink, and is more suitable for moving in harsh underground working environments than wheeled walking devices. The left and right sides of the crawler walking part 2 are fixedly connected to two groups of supporting hydraulic cylinders 4 through cross beams, and the output ends of the four groups of supporting hydraulic cylinders 4 are fixedly connected to support plates 5. After the drilling vehicle reaches the working position, the supporting hydraulic cylinders 4 are started, and their output ends push the support plates 5 down and make close contact with the ground, which can support and fix the drilling vehicle as a whole, effectively increasing the stability of the drilling vehicle during drilling operations, avoiding shaking or displacement of the drilling vehicle due to the reaction force generated by drilling, and ensuring the accuracy and quality of drilling. The front and rear sides of the left end of the mounting shell 1 are rotatably connected to the rotating bottom The seat 7, the upper ends of the two groups of rotating bases 7 are fixedly connected to the rotating table 8 through the top wall of the mounting shell 1, and a drilling assembly 11 is installed above the two rotating tables 8. The upper ends of the two groups of rotating bases 7 are fixedly connected to the rotating table 8 through the top wall of the mounting shell 1, providing a rotation basis for the drilling assembly 11, so that the drilling assembly 11 can rotate in the horizontal direction, so that the drilling angle and position can be flexibly adjusted to meet the needs of different working positions and drilling directions. A first gear disk 9 is fixedly connected to the lower side of the outer surface of the front rotating base 7, and a second gear disk 10 is fixedly connected to the upper side of the outer surface of the rear rotating base 7. A double-station switching assembly 12 is provided on the right side of the rotating base 7 inside the mounting shell 1. The first gear disk 9 and the second gear disk 10 realize independent control and station switching of the front and rear groups of drilling assemblies 11. Through the meshing transmission of the gears, the rotation angle of the rotating base 7 can be accurately controlled, and then the horizontal angle of the drilling assembly 11 can be accurately adjusted.

[0021] Furthermore, a power supply unit 3 for providing hydraulic power is fixedly installed on the right side inside the installation shell 1, and an operating driving unit 6 for operation is fixedly installed on the right side above the installation shell 1. The power supply unit 3 provides stable and sufficient hydraulic power for various hydraulic actuators of the drilling vehicle, ensuring that the drilling vehicle has sufficient power support during operations such as drilling and supporting, thereby improving operational efficiency and reliability. At the same time, it also provides the required electricity for various motors of the drilling vehicle. The operating driving unit 6 facilitates the operator to fully control and operate the drilling vehicle, enabling the operator to clearly observe the surrounding environment of the drilling vehicle and the drilling operation status, and timely adjust parameters such as the movement of the drilling vehicle, drilling angle and depth, thereby improving the safety and accuracy of the operation.

[0022] Example 2 Specifically, the drilling assembly 11 includes a fixed base 1101, which is fixedly connected to the top of the rotating table 8. A rotating arm 1102 is rotatably connected to the top of the fixed base 1101 through a rotating shaft. A rotating arm 1104 is rotatably connected to the top of the rotating arm 1102 through a rotating shaft. An adjustment plate 1106 is fixedly connected to the upper side of the rotating arm 1104.

[0023] Preferably, a first rotating hydraulic rod 1103 is rotatably installed on both sides of the front and rear of the rotating arm 1102 above the fixed base 1101, and the output end of the first rotating hydraulic rod 1103 is rotatably connected to the middle part of the rotating arm 1102 through a connecting piece, and a second rotating hydraulic rod 1105 is rotatably installed in the middle part above the rotating arm 1102, and the output end of the second rotating hydraulic rod 1105 is rotatably connected to the upper end of the rotating arm 1104 through a connecting piece. Through the extension and retraction of the first rotating hydraulic rod 1103, the rotating arm 1102 can be pushed to rotate around the rotating axis of the fixed base 1101, thereby adjusting the pitch angle of the rotating arm 1102, so that the drill rod 1113 can perform drilling operations at different heights and angles, and the extension and retraction of the second rotating hydraulic rod 1105 can push the rotating arm 1104 to rotate around the rotating axis at the top of the rotating arm 1102, further fine-tuning the angle of the rotating arm 1104, so that the drill rod 1113 can be more accurately aligned with the target drilling position, thereby improving the accuracy and flexibility of drilling.

[0024] Specifically, a fixed frame 1107 is fixedly connected above the adjustment plate 1106, and two groups of movable guide rails 1108 are fixedly connected above the fixed frame 1107. A sliding plate 1109 is slidably connected above the two groups of movable guide rails 1108 through sliding blocks. Two groups of connecting bars 1110 are fixedly connected to the front and rear sides of the sliding plate 1109. The four groups of connecting bars 1110 are rotatably connected to the side away from the sliding plate 1109. The four groups of rotating wheels 1111 are all in contact with the upper edge of the fixed frame 1107. This structure enables the sliding plate 1109 to move horizontally steadily and smoothly on the movable guide rail 1108, and the rotating wheel 1111 rolls along the edge of the fixed frame 1107 to assist in sliding, effectively reducing friction during sliding and reducing energy loss. At the same time, it also improves the accuracy and stability of the movement of the sliding plate 1109, providing reliable guarantee for the feeding action of the drill rod 1113.

[0025] Specifically, the fixed frame 1107 is internally connected to two rotating rods 1114, and the middle of the outer surface of the two rotating rods 1114 is fixedly connected to a driving sprocket 1115. A transmission chain 1116 is connected between the two sets of driving sprockets 1115. The upper chain of the transmission chain 1116 is fixedly connected to the bottom surface of the sliding plate 1109 through a connecting piece. A feed motor 1117 for driving the rotating rod 1114 to rotate is fixedly installed on the side above the fixed frame 1107. The main The output end of the spindle motor 1112 is fixedly connected to the drill rod 1113 through a coupling, and the feed motor 1117 drives the rotating rod 1114 to rotate, driving the drive sprocket 1115 and the transmission chain 1116 to operate. The transmission chain 1116 pulls the sliding plate 1109 through the connecting piece to move horizontally along the movable guide rail 1108, thereby realizing the automatic feeding action of the drill rod 1113. This transmission method has a simple and reliable structure, can provide a large feed force, and can meet the needs of drilling operations under different geological conditions.

[0026] Example 3 It is worth noting that the double-station switching assembly 12 includes a support plate 1201, the upper end of the support plate 1201 is fixedly connected to the internal top wall of the mounting shell 1, and two first guide rods 1202 are fixedly connected to the left bottom surface of the support plate 1201. A lifting threaded rod 1203 is rotatably connected to the left bottom surface of the support plate 1201 between the two first guide rods 1202. Two sliding members 1207 are fixedly connected to the outer surfaces of the two first guide rods 1202. A movable plate 1208 is fixedly connected to the left side of the four sliding members 1207. The middle right side of the movable plate 1208 is threadedly connected to the lifting threaded rod 1203 through a threaded seat. This structure enables the movable plate 1208 to be driven by the rotation of the lifting threaded rod 1203 and to be lifted and lowered smoothly and accurately along the lifting threaded rod 1203 under the guidance of the first guide rod 1202 and the sliding member 1207, thereby providing accurate position adjustment for subsequent station switching.

[0027] It is worth noting that the left side of the movable plate 1208 is fixedly connected to a support frame 1209, and the left side of the support frame 1209 is rotatably connected to a rotating shaft 1210 through a bearing. The lower end of the outer surface of the rotating shaft 1210 is fixedly connected to a first gear 1211, and the upper end of the outer surface of the rotating shaft 1210 is fixedly connected to a second gear 1212. The upper half of the first gear 1211 is engaged with the first toothed disc 9, and the lower half of the second gear 1212 is engaged with the second toothed disc 10. The top of the rotating shaft 1210 passes through the top wall of the mounting shell 1 and is fixedly connected to a transmission gear 1213. Regarding the problem of meshing of the first gear 1211 and the first toothed disc 9, and meshing and colliding of the second gear 1212 and the second toothed disc 10, in the prior art, there are corresponding solutions when the automobile engine is ignited, so no excessive elaboration is made in this embodiment. Figure 2The state shown therein is that when the two groups of drilling assemblies 11 work synchronously, the first gear 1211 is engaged with the first toothed disc 9, and the second gear 1212 is engaged with the second toothed disc 10. This connection method can realize the synchronous opposite movement of the two groups of drilling assemblies 11. By raising and lowering the movable plate 1208, the first gear 1211 and the second gear 1212 can be engaged or disengaged with the first toothed disc 9 or the second toothed disc 10 respectively, thereby realizing the station switching of the front and rear groups of drilling assemblies 11. This design cleverly utilizes the meshing transmission of the gears, has a compact structure, reliable transmission, and can accurately control the rotation angle of the drilling assembly 11.

[0028] It is worth noting that the top of the lifting threaded rod 1203 passes through the top wall of the mounting shell 1 and is fixedly connected to the first bevel gear 1204, and the work station switching motor 1205 is fixedly connected to the middle position of the top of the mounting shell 1, and the output end of the work station switching motor 1205 is fixedly connected to the second bevel gear 1206, and the second bevel gear 1206 is meshed with the first bevel gear 1204. The top wall of the mounting shell 1 is fixedly connected to the drive motor 1214 on the left side of the rotating shaft 1210, and the output end of the drive motor 1214 passes through the top wall of the mounting shell 1 and is fixedly connected to the rotating gear disk 1215, and the rotating gear disk 1215 is meshed with the transmission gear 1213. The length of the transmission gear 1213 is set to meet the requirement that the rotating gear disk 1215 will not disengage from the transmission gear 1213 when the movable plate 1208 moves. The workstation switching motor 1205 drives the lifting threaded rod 1203 to rotate through the meshing transmission of the second bevel gear 1206 and the first bevel gear 1204, thereby realizing the lifting and lowering of the movable plate 1208. This transmission method can realize the conversion of the rotational motion of the motor to the linear motion of the threaded rod. It has a simple structure, high transmission efficiency, and is easy to realize automatic control. The driving motor 1214 drives the rotating shaft 1210 to rotate through the meshing transmission of the rotating gear plate 1215 and the transmission gear 1213, thereby driving the rotating base 7 and the rotating table 8 meshed therewith to rotate, thereby realizing the adjustment of the horizontal angle of the drilling assembly 11. This design ensures that during the workstation switching process, the driving motor 1214 can continuously provide power to the rotating shaft 1210, thereby improving the reliability and stability of the system.

[0029] It is worth noting that the double-station switching assembly 12 also includes two fixed plates 1216, which are fixedly connected to the front and rear sides of the upper surface of the mounting shell 1 and correspond to the two sets of rotating bases 7. The middle of the right side of the two fixed plates 1216 is fixedly connected to a pushing hydraulic cylinder 1217. The output ends of the two sets of pushing hydraulic cylinders 1217 are fixedly connected to an annular friction pad 1219. The height of the annular friction pad 1219 corresponds to the height of the rotating table 8. The two fixed plates 1216 are slidably connected to the second guide rod 121 on both sides of the pushing hydraulic cylinder 1217. 8. The left end of the second guide rod 1218 is fixedly connected to the right side of the annular friction pad 1219. When it is necessary to independently control the operation of another drilling assembly 11, the annular friction pad 1219 is first pushed to contact the currently working turntable 8 by pushing the hydraulic cylinder 1217, and the friction force is used to lock the drill arm to avoid the drill arm from rotating during the workstation switching process, thereby ensuring the accuracy and safety of the workstation switching. The second guide rod 1218 provides a guiding effect for the movement of the annular friction pad 1219, so that the annular friction pad 1219 can smoothly and accurately contact and separate from the turntable 8.

[0030] Working principle: The crawler walking part 2 is controlled by operating the driving part 6 to move the drilling vehicle as a whole to the working position of the laneway or tunnel. After reaching the position, the supporting hydraulic cylinders 4 on both sides of the crawler walking part 2 are started, and the output end thereof pushes the supporting plate 5 to descend and make close contact with the ground, thereby supporting and fixing the drilling vehicle as a whole to avoid shaking or displacement during drilling. The first rotating hydraulic rod 1103 on the fixed base 1101 is extended and retracted, pushing the rotating arm 1102 to rotate around the rotating axis of the fixed base 1101, adjusting the pitch angle of the rotating arm 1102, and the second rotating hydraulic rod 1105 on the rotating arm 1102 is extended and retracted, pushing the rotating small arm 1104 to rotate around the rotating axis at the top of the rotating large arm 1102, further adjusting the angle of the rotating small arm 1104, so that the drill rod 1113 is aligned with the target drilling position, and the spindle motor 1112 is started, driving the drill rod 1113 to rotate at high speed through the coupling, preparing for drilling, and the feed motor 1117 drives the rotary The movable rod 1114 rotates, driving the driving sprocket 1115 and the transmission chain 1116 to operate. The transmission chain 1116 pulls the sliding plate 1109 to move horizontally along the movable guide rail 1108 through the connecting piece, and the rotating wheel 1111 rolls along the edge of the fixed frame 1107 to assist in sliding, reducing friction, and realizing the feeding action of the drill rod 1113. If it is necessary to independently control the operation of another drilling assembly 11, first push the hydraulic cylinder 1217 to push the annular friction pad 1219 to contact the currently working rotary table 8, and use the friction force to lock the drill arm to prevent rotation during switching. Start the work station switching motor 1205, and its output end drives the second bevel gear 1206 to rotate, and drives the lifting threaded rod 1203 to rotate by meshing with the first bevel gear 1204. The movable plate 1208 is lifted and lowered along the lifting threaded rod 1203 under the guidance of the first guide rod 1202 and the sliding member 1207, driving the support frame 1209 and the rotating shaft 1210 to lift and lower synchronously. Figure 2 For example, if it is necessary to switch to the rear drilling assembly 11, the movable plate 1208 is lowered, so that the first gear 1211 at the lower end of the rotating shaft 1210 is completely disengaged from the first gear plate 9 of the front rotating base 7, and the upper half of the second gear 1212 is engaged with the second gear plate 10 at the rear side. Figure 2For example, if it is necessary to switch to the front drilling assembly 11, the movable plate 1208 rises, so that the second gear 1212 at the upper end of the rotating shaft 1210 is completely disengaged from the second gear disc 10 of the rear rotating base 7. At this time, the lower half of the first gear 1211 is engaged with the front first gear disc 9, and the drive motor 1214 is started. Its output end drives the rotating gear disc 1215 to rotate, and drives the rotating shaft 1210 to rotate by engaging with the transmission gear 1213. The rotating shaft 1210 drives the corresponding rotating base 7 and the rotating table 8 to rotate through the engaged gears (the first gear 1211 or the second gear 1212), so as to realize the angle adjustment of the drilling assembly 11, such as horizontal rotation to align with the new drilling position. After completing the drill arm angle and position adjustment, the spindle motor 1112 and the feed motor 1117 of the drilling assembly 11 are started, and the drill rod 1113 rotates and feeds to complete the drilling operation.
