Description

Technical Field

[0001] This utility model relates to a mechanical device, and more particularly to a multi-functional integrated mechanical device for tunneling faces. Background Technology

[0002] Currently, in the mining industry, rapid tunneling equipment and construction techniques have greatly improved, and various types of rapid tunneling equipment have emerged in China. Typical rapid tunneling equipment solutions include:

[0003] 1. Tunneling machine onboard temporary support + pneumatic outrigger anchor drilling rig.

[0004] The conclusion is that this method represents a significant improvement over traditional pipe-driven methods, transforming point support into area support. However, the support materials are still manually transported to the tunnel face, and the drilling equipment remains a pneumatic drill, which is noisy, has low power, and low drilling efficiency.

[0005] 2. Tunneling machine + stepping gantry support

[0006] The conclusion is that it has a larger supporting area and greater supporting force than the machine-mounted temporary support, and anchor bolt holes can be drilled at the tail end. However, due to its structural form, the equipment is only suitable for roadways with a small inclination angle. The support materials are transported manually to the tunneling face, and the drilling equipment is still a pneumatic drilling rig.

[0007] 3. Integrated excavation, anchoring, and protection machine

[0008] Currently, the best equipment for rapid tunneling in China is the integrated tunneling, anchoring, and support machine. Using a tunneling machine as a carrier, it is equipped with onboard temporary support and two hydraulic drilling rigs. One machine can perform tunneling, support, and drilling / anchoring, making it the best choice for rapid tunneling. However, it still has the following shortcomings:

[0009] ① Support materials are still manually transported to the tunneling face.

[0010] ② When encountering semi-coal and rock tunneling, excessive vibration may damage the temporary support structure.

[0011] ③ Currently, tunneling machines are widely used in the mining industry. If the tunneling and anchoring functions are to be realized, the existing tunneling machines need to be modified, which will affect production operations.

[0012] In conclusion, there is an urgent need for an integrated excavation, anchoring, and protection machine that can overcome the above shortcomings, thereby reducing the labor intensity of workers and improving operational safety and efficiency. Utility Model Content

[0029] The objectives and functions of this invention, as well as the methods for achieving these objectives and functions, will be clarified by referring to exemplary embodiments. However, this invention is not limited to the exemplary embodiments disclosed below; it can be implemented in various forms. The purpose of this specification is merely to help those skilled in the art to comprehensively understand the specific details of this invention.

[0030] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0031] Figure 1 The illustration shows a multi-functional integrated mechanical device 100 for a tunneling face according to the present invention. The multi-functional integrated mechanical device 100 includes a bottom traveling mechanism 1, a support frame 2 located above the bottom traveling mechanism 1, a telescopic beam 3 fixed to the upper end of the support frame 2 and extending outward, and a liftable temporary support mechanism 4 connected above the outer end of the telescopic beam 3.

[0032] The multi-functional integrated mechanical device 100 also includes a support material conveying mechanism 5 located above the support frame 2 and a support material feeding mechanism 6 located on the receiving end side of the support material conveying mechanism 5 and which can be flipped. The support material passes through the support material feeding mechanism 6 and the support material conveying mechanism 5 in sequence and then smoothly arrives above the temporary support mechanism 4. The support material is mainly steel strip or anchor mesh, which is used to support the roof of the tunnel. It does not require manual transportation and installation and has the characteristics of high efficiency and high safety.

[0033] Preferably, the bottom walking mechanism 1 is a tracked walking mechanism and a cantilevered anchor drilling rig 8 with multiple degrees of freedom and omnidirectional operation is set above its front end for anchoring the support material. Furthermore, a floating coal cleaner 9 is set in front of the bottom walking mechanism 1 to clean up floating coal and avoid obstructing the normal movement of the bottom walking mechanism 1.

[0034] This multi-functional integrated mechanical device 100 is independent of the tunneling machine body and is mainly used to achieve support and anchoring operations while the tunneling machine is tunneling. The tunneling work and support and anchoring operations do not interfere with each other, which is different from the existing tunneling machine on-board support and on-board anchoring operation methods. It has many advantages such as high efficiency, stability and safety, and low system complexity.

[0035] Specifically, the temporary support mechanism 4 includes a scissor lift mechanism 41 and a temporary support platform 42 located above the scissor lift mechanism 41. Compared with existing tunneling machine-mounted four-bar linkage composite mechanisms or onboard cantilever mechanisms, the scissor lift mechanism 41 has advantages such as high vertical lifting efficiency, large load-bearing capacity, and stable center of gravity. In addition, since the temporary support mechanism 4 operates independently of the tunneling machine, the tunneling machine does not need to be stopped during operation (compared to the onboard support method of the tunneling machine), and the two operations do not affect each other, thereby further improving their respective operating efficiency; furthermore, the temporary support mechanism 4 can also move back and forth through the telescopic beam 3, expanding the operating range.

[0036] like Figure 2 As shown, the support frame 2 is a gantry frame type, including columns 21, longitudinal beams 22 and crossbeams 23 located at the upper ends of the columns 21. A transmission mechanism 52 is also provided on the outer side of the crossbeams 23. The transmission mechanism 52 includes a drive mechanism 52a, a drive shaft 52b, and a transmission chain 52c connecting the drive mechanism 52a and the drive shaft 52b. Preferably, this transmission mechanism 52 is located between the support material conveying mechanism 5 and the support material feeding mechanism 6, and can simultaneously and synchronously drive both the support material conveying mechanism 5 and the support material feeding mechanism 6, thereby reducing system complexity and possessing advantages such as simple and compact structure, high efficiency, and energy saving.

[0037] like Figure 3As shown, the support material conveying mechanism 5 includes multiple parallel first longitudinal pipes 51 fixed to the top of the crossbeam 23, and a first chain 53 passing through the first longitudinal pipes 51 and driven by a drive shaft 52b. Preferably, a drive sprocket and a driven sprocket for driving the first chain 53 are respectively provided on both ends of the first longitudinal pipes 51, wherein the drive sprocket is mounted on the drive shaft 52b and is powered by the transmission mechanism 52.

[0038] The support material feeding mechanism 6 includes multiple parallel-arranged second longitudinal tubes 61, one end of which is movably connected to the drive shaft 52b and the other end of which can rotate up and down around the drive shaft 52b; and a second chain 63 passing through the second longitudinal tubes 61 and driven by the drive shaft 52b. Further, the second longitudinal tubes 61 are rotated up and down by a hydraulic push rod 62, one end of which is movably connected to the crossbeam 23 and the other end of which is movably connected to the second longitudinal tubes 61. The drive shaft 52b is movably connected to the second longitudinal tubes 61 via bearings. Preferably, each end of the second longitudinal tube 61 is also provided with a driving sprocket and a driven sprocket for driving the second chain 63, wherein the driving sprocket is mounted on the drive shaft 52b and is powered by the transmission mechanism 52.

[0039] Preferably, multiple roller assemblies 7 are also provided at equal intervals on the outer ring of the first chain 53 and the second chain 63. Furthermore, the roller assembly 7 also includes a roller seat and a nylon roller, thereby reducing the friction between the support material and the support material conveying mechanism 5 and the support material feeding mechanism 6, and realizing the smooth transportation and transition of the support material.

[0040] like Figure 4 As shown, this utility model also describes a construction method utilizing the above-mentioned integrated mechanical device, which mainly includes the following steps:

[0041] (A) The support material feeding mechanism 6 is in an inclined state, and the support material is laid on the support material feeding mechanism 6;

[0042] (B) The tunneling machine starts working, and the support material feeding mechanism 6 flips upward to a horizontal state and conveys the laid support material to the support material conveying mechanism 5.

[0043] (C) After the tunneling machine moves forward a certain distance, the multi-functional integrated mechanical device moves forward as well. The support material conveying mechanism 5 conveys the support material to the temporary support mechanism 4. At the same time, the support material feeding mechanism 6 flips down to an inclined state and lays the support material again.

[0044] (D) The temporary support mechanism 4 supports the support material to the top plate of the tunneling face, and at the same time flips the support material feeding mechanism to a horizontal state, and transfers the laid support material to the support material conveying mechanism 5.

[0045] (E) The cantilevered anchor drilling rig 8 performs anchoring operations on the support material. After the anchoring is completed, the temporary support mechanism 4 is lowered to the same plane as the support material conveying mechanism 5, and then the cycle operation of step (C) is resumed.

[0046] The above devices enable the continuous and stable transportation of support materials (anchor mesh or steel strip, etc.) to the temporary support mechanism 4, which is then vertically lifted to the top plate by the support mechanism 4. At the same time, the cantilevered anchor drilling rig 8 performs anchoring operations on the support materials, which greatly reduces the labor intensity of workers and improves the safety of workers.

[0047] In summary, this utility model presents a multi-functional integrated mechanical device for tunneling faces, creatively employing independent design and automated support and anchoring operations. This device is multi-functional, featuring an independent power system and self-propelled capability. With the tracked walking section as its anchor point, its structure is a gantry frame, with the power system and hydraulic anchor drilling rig arranged on both side columns. It also has a support material (steel strip or anchor mesh) conveying mechanism, enabling secondary transport of support materials (steel strip or anchor mesh) to the face support device, thus achieving continuous network connection and rapid tunneling. It can be widely applied in mining, coal mining, and tunneling scenarios without requiring modification of existing tunneling machines. It boasts numerous advantages, including safety, high efficiency, stability, reliability, high integration, simple operation, ease of use, and wide applicability.
