[0001] This invention relates to the field of integrated mechanized tunneling technology in underground coal mines, and particularly to a drilling and anchoring integrated four-arm bolt transfer unit for use with tunneling machines. Background Technology

[0002] In integrated mechanized tunneling systems, especially in rapid tunneling processes where tunneling machines such as roadheader-anchor-jacking machines are used as the main tunneling equipment at the face, anchor bolt and cable support have become key factors restricting tunneling efficiency and tunnel quality.

[0003] To meet the requirements of timely support for surrounding rock, existing technologies typically employ two solutions: The first is to deploy more drilling rigs in the face area of ​​the tunneling working face, including manually operated handheld drilling rigs and anchor bolt drilling arms integrated into the tunneling and anchoring machine; the second is, under the premise of stable geological conditions and support design, to postpone some anchor bolt and anchor cable support operations, using manual drilling rigs or deploying anchor bolt transfer units for post-installed anchor bolt and anchor cable support.

[0004] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art: On the one hand, due to the limitations of the tunneling machine's own process flow, it is difficult to develop a bolt transfer unit that can work efficiently and independently with the tunneling and bolting machine. On the other hand, most existing bolt transfer units are designed with fixed row spacing, which makes them poorly adaptable to changes in support design parameters (such as the spacing and row spacing of bolt and cable supports).

Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] The following is for reference. Figures 1 to 7 This describes a drilling and anchoring integrated four-arm anchor bolt transfer unit for use with a tunneling machine according to an embodiment of the present invention.

[0029] Combination Figure 1 and Figure 5 As shown, a drilling and anchoring integrated four-arm bolt transfer unit for a tunneling machine according to an embodiment of the present invention includes a frame assembly 14, a left side anchoring mechanism 4, a right side anchoring mechanism 3, and a top anchoring mechanism 6.

[0030] The frame assembly 14 is the basic connecting component for each functional component in the anchor bolt transfer unit.

[0031] The left and right side anchoring mechanisms 4 and 3 are slidably installed on the left and right sides of the frame assembly 14, respectively, and can move in the front-to-back direction to complete the anchoring operation on the roadway side. The front-to-back movement of the left and right side anchoring mechanisms 4 and 3 can be driven by cylinders, hydraulic cylinders, etc. The left and right side anchoring mechanisms 4 and 3 have the same structure. The left and right side anchoring mechanisms 4 and 3 operate independently and can move back and forth as a whole, with a large stroke, which improves the adaptability to the design parameters of the anchor bolts and cables.

[0032] The top anchoring mechanism 6 includes two sets of top drilling rig assemblies 601. The top drilling rig assemblies 601 are mounted on the frame assembly 14, located behind the left side anchoring mechanism 4 and the right side anchoring mechanism 3. Each top drilling rig assembly 601 is equipped with a double-side sliding assembly 604, allowing it to move independently in the left and right directions. The movement trajectory of the top drilling rig assembly 601 traverses the central area of ​​the roadway. The double-side sliding assembly 604 is slidably mounted on the frame assembly 14 to complete the anchoring operation on the roadway roof. The central area of ​​the roadway refers to the center of the roadway roof and the middle of both sides. The left and right movement of the top drilling rig assembly 601 can be driven by cylinders, hydraulic cylinders, etc. The bottom of the double-side sliding assembly 604 is equipped with a mounting base, and the frame assembly 14 is equipped with guide rails arranged in the front-to-back direction. The mounting base is slidably connected to the guide rails and driven by hydraulic cylinders.

[0033] It should be noted that the left side anchoring mechanism 4, the right side anchoring mechanism 3, and the two sets of top drilling rig components 601 are configured to install integrated drilling and anchoring drill rods. Traditional drill rods require six steps to complete, including drilling, unloading the drill rod, installing the anchoring agent, inserting the anchor rod, mixing, and pre-tightening. However, integrated drilling and anchoring drill rods greatly reduce the process.

[0034] According to an embodiment of the present invention, a drilling and anchoring integrated four-arm anchor bolt transfer unit for a tunneling machine is provided. By setting up a left side anchoring mechanism 4, a right side anchoring mechanism 3 and two sets of top drilling rig components 601, a four-arm collaborative operation layout is formed, which can simultaneously complete the anchoring operation of the left side, right side and top of the roadway, significantly improving support efficiency and shortening the cycle operation time.

[0035] In some embodiments, combined with Figures 1 to 3 As shown, the drilling and anchoring integrated four-arm anchor bolt transfer unit also includes a hopper assembly 1, a personnel lifting platform 7, a traveling unit 8, an unloading unit 10, a driver's cab 11, a hydraulic system 12, and an electrical system 13.

[0036] The hopper assembly 1 is located in front of the frame assembly 14. Its main function is to receive materials transported by the face-heading tunneling equipment and to serve as a storage point for subsequent transport. The hopper assembly 1 has a hopper swing cylinder, which enables the hopper assembly 1 to swing up and down. The hopper assembly 1 is relatively long in the front-to-back direction, accounting for one-quarter to one-third of the length of the entire anchor bolt transfer unit, which can improve the current situation of frequent machine relocation in the integrated mechanized tunneling system with tunneling machines as the face-heading equipment. The personnel lifting platform 7 is located behind the top anchoring mechanism 6 and is designed to meet the support operation requirements of anchor bolts and anchor cables at different heights of the roof. The traveling unit 8 can be in the form of tracks, which provides support for the whole machine and drives the whole machine to move forward, backward, and turn. The unloading unit 10 is located behind the frame assembly 14. Its function is to transfer the materials transferred by the anchor bolt transfer unit to the belt transfer conveyor. At the same time, in order to improve the overall mobility of the machine, the unloading unit 10 can pitch up and down relative to the frame assembly 14. The function of the operator's cab 11 is to acquire overall machine information and operate all machine components except for anchor bolt support. The function of the hydraulic system 12 is to pump hydraulic oil to each actuator and drive the actuator to move. The function of the electrical system 13 is to provide power and control to the hydraulic system 12 and various electrical components.

[0037] In addition, the integrated drill-anchor four-arm bolt transfer unit for the tunneling machine also includes an anchoring agent tank 2 and a grouting pump 5. The anchoring agent tank 2 and grouting pump 5 are mounted on the frame assembly 14. The anchoring agent tank 2 stores two types of anchoring agents separately. The grouting pump 5 injects the two anchoring agents into the end of the drill rod that has been drilled, causing the anchoring agent to overflow to the borehole end. It is understood that the two anchoring agents, when mixed, can form a high-strength solidified body, achieving reliable anchoring between the drill rod and the borehole wall.

[0038] In some embodiments, combined with Figure 3 and Figure 4 As shown, the drilling and anchoring integrated four-arm bolt transfer unit for the matching tunneling machine also includes front and rear sliding cylinders. One end of the front and rear sliding cylinders is connected to the left side anchoring mechanism 4, and the other end is connected to the side of the frame assembly 14. Through the front and rear sliding cylinders, the left side anchoring mechanism 4 can slide relative to the frame assembly 14 along the front and rear direction of the roadway.

[0039] Specifically, the left-side anchoring mechanism 4 includes a side-side lifting mechanism 401, a side-side drilling rig swing cylinder 402, a side-side sliding seat 403, a side-side drilling rig support seat 404, a side-side drilling rig assembly 405, a valve box 406, and a side-side operating platform 407. One end of the forward and backward pushing cylinder is connected to the inside of the side-side sliding seat 403. The side-side lifting mechanism 401 and the valve box 406 are respectively connected to the front and rear ends of the side-side sliding seat 403. The side-side operating platform 407 is suspended below the outer side of the valve box 406. The side-side lifting mechanism 401 is slidably connected to the side-side drilling rig swing cylinder 402, and is used to drive the side-side drilling rig swing cylinder 402 to move up and down. The side-side drilling rig swing cylinder 402 is connected to the side-side drilling rig assembly 405, and is used to drive the side-side drilling rig assembly 405 to swing left and right. The side-side lifting mechanism 401, the side-side sliding seat 403, the side-side drilling rig assembly 405, the valve box 406, and the side-side operating platform 407 move forward and backward synchronously. The valve box 406 and the auxiliary control platform 407 slide back and forth as a whole, so the distance between the operator's position and the auxiliary drilling rig assembly 405 remains unchanged, which improves operational convenience. In one example, the auxiliary control platform 407 is hinged to the valve box 406, allowing it to be laid flat or folded upwards when not in operation, saving space.

[0040] Combination Figure 5 and Figure 6 As shown, in some embodiments, the top anchoring mechanism 6 further includes a top lifting mechanism 602, a front-to-back swing cylinder 603, and a double-side sliding assembly 604. The double-side sliding assembly 604 is located in front of the top drilling rig assembly 601 and includes two top sliding seats 6045 that can slide independently in the left-right direction, used to move the top drilling rig assembly 601 in the left-right direction with its movement trajectory passing through the middle area of ​​the roadway. The top lifting mechanism 602 is located on the top sliding seats 6045 and includes a drilling rig support seat 6026 that can move in the up-down direction. The top drilling rig assembly 601 is located on the drilling rig support seat 6026. One end of the front-to-back swing cylinder 603 is connected to the top drilling rig assembly 601, and the other end is connected to the top lifting mechanism 602, used to swing the top drilling rig assembly 601 back and forth.

[0041] It should be noted that the range of motion of the top sliding seat 6045 should be such that the top drilling rig assembly 601 can meet the needs of both the sidewall operation and the top operation, especially the middle area.

[0042] In this embodiment of the invention, the top drilling rig 601 in the bolt transfer unit is equipped with a double-side sliding assembly 604. The double-side sliding assembly 604 can drive two sets of top drilling rig 601 to move in the left and right directions, and its movement trajectory runs through the middle area of ​​the roadway. Combined with the top lifting mechanism 602 and the front and rear swing cylinder 603, the top drilling rig 601 can perform bolt and cable support operations on the middle area of ​​the roadway top, eliminating blind spots in the support operation.

[0043] Combination Figure 5and Figure 6 As shown, in some embodiments, the top lifting mechanism 602 further includes a slide rail base 6021, a lifting cylinder 6022, a rotary support 6023, a rotary support 6024, a left-right swing cylinder 6025, and a sliding base 6027. The front side of the slide rail base 6021 is connected to the top sliding seat 6045, and the rear side of the slide rail base 6021 has a vertically arranged slide rail. The sliding base 6027 slides with the slide rail. The cylinder end of the lifting cylinder 6022 is connected to the slide rail base 6021, and the piston rod end of the lifting cylinder 6022 is connected to the sliding base 6027. The rotary support 6023 is disposed on the sliding base 6027, the rotary support 6024 is disposed on the rotary support 6023, and the drilling rig support 6026 is disposed on the rotary support 6024. One end of the left-right swing cylinder 6025 is connected to the slewing support 6023, and the other end is connected to the drilling rig support 6026, used to drive the top drilling rig assembly 601 to swing left and right. In other words, driven by the left-right swing cylinder 6025, the drilling rig support 6026 connected to the top drilling rig assembly 601 can swing left and right relative to the top lifting mechanism 602, further expanding the working range of the top drilling rig assembly 601.

[0044] like Figure 7 As shown, the dual-side sliding assembly 604 also includes a support base 6041, a first telescopic unit, and a second telescopic unit. The first and second telescopic units are mounted on the support base 6041 and are respectively connected to two sets of top drilling rig assemblies 601. The first and second telescopic units have identical structures and can drive the left and right side top sliding seats 6045 to slide independently in the left-right direction. The installation method of the second telescopic unit is 180 degrees symmetrical to the first telescopic unit, with the center of symmetry located on the transverse center line. Additionally, multiple reinforcing ribs can be designed on the support base 6041 to improve structural strength.

[0045] The first telescopic unit includes an inner pushing cylinder 6042, an outer pushing cylinder 6043, and an inner sleeve 6044. The inner sleeve 6044 is slidably engaged with the upper half of the support base 6041. The cylinder end of the inner pushing cylinder 6042 is installed inside the inner sleeve 6044, and the piston rod end of the inner pushing cylinder 6042 is installed on one side of the support base 6041. The top sliding seat 6045 is slidably engaged with the inner sleeve 6044. The cylinder end of the outer pushing cylinder 6043 is installed on the inner sleeve 6044, and the piston rod end of the outer pushing cylinder 6043 is connected to the top sliding seat 6045.

[0046] from Figure 3As can be seen, the piston rods of the inner push cylinder 6042 and the outer push cylinder 6043 point to the two ends of the support base 6041, respectively. During the extension of the piston rod of the inner push cylinder 6042, it can push the inner sleeve 6044 to slide to the right. During the extension of the piston rod of the outer push cylinder 6043, it can push the top sliding seat 6045 to slide to the right. The oil passage blocks of the external hoses of the inner push cylinder 6042 and the outer push cylinder 6043 are arranged on the cylinder barrels of these two cylinders. In the double-sided sliding assembly 604, the inner push cylinder 6042 and the outer push cylinder 6043 are connected in parallel, pushing the inner sleeve 6044 and the top sliding seat 6045 to slide to the right, respectively. The cylinder barrels of the inner push cylinder 6042 and the outer push cylinder 6043 are fixed relative to the inner sleeve 6044. Both sets of top drilling rig assemblies 601 can slide in two stages from the center of the machine to both sides, which greatly adapts to the spacing design of the roof anchor bolts and cables. At the same time, the large displacement sliding combination of the two sets of top drilling rig assemblies 601 with the left side anchoring mechanism 4 and the right side anchoring mechanism 3 can achieve a wider range of top and side drilling rig spacing, which is very friendly to the design of the anchor bolt and cable support spacing in the roadway.

[0047] In addition, the cylinder ends and piston rod ends of the inner thrust cylinder 6042 and the outer thrust cylinder 6043 are connected to their respective positions via pin lugs. The working principle of the second telescopic unit is the same as that of the first telescopic unit, and will not be described again here.
