Description

Technical Field

[0001] This utility model relates to the field of boring device technology, and in particular to a portable boring device for mining machinery. Background Technology

[0002] In mining, tunnel construction, and other fields, it is often necessary to perform on-site boring in tunnel walls or support structures, for example, to install anchor bolts, equipment bases, or pipeline supports. Currently, on-site boring operations mainly employ the following two methods:

[0003] Method 1: Fixed boring equipment. A large boring machine or specialized boring machine is fixed to a mining flatbed truck or a temporarily constructed base. The drawback of this method is:

[0004] Extremely poor mobility: The equipment is heavy and requires heavy locomotives or winches for traction, making it almost impossible to maneuver flexibly in complex tunnel networks.

[0005] Deployment efficiency is extremely low: each relocation requires re-fixing and leveling, and the whole process takes up to several hours, which seriously affects tunneling efficiency.

[0006] Obstruction of passageways: Large pieces of equipment occupy limited alleyway space for extended periods, creating traffic bottlenecks and affecting the passage of other equipment and personnel.

[0007] Method Two: Handheld Small Tools. Use a low-powered electric drill or hydraulic drill with simple tooling to enlarge the hole. While this method is flexible, it has significant drawbacks:

[0008] Poor machining accuracy: It is impossible to guarantee the dimensional and positional accuracy of the holes, which seriously affects the quality of subsequent installation.

[0009] Limited capabilities: It is completely incapable of boring large-diameter, deep holes.

[0010] High labor intensity: Relies on manual support, poor stability, and low operational safety.

[0011] Therefore, there is an urgent need in this field for a dedicated portable boring device that can meet the accuracy and power requirements of boring in mines, while also possessing high mobility and rapid deployment capabilities. Utility Model Content

[0012] The purpose of this invention is to provide a portable boring device for mining machinery, which solves the problems of low deployment efficiency, poor spatial mobility, and difficulty in balancing portability and processing accuracy of existing boring devices in mine roadways.

[0013] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0014] This utility model discloses a portable boring device for mining machinery, comprising a movable frame, a folding mechanism on the top of the movable frame, a mounting plate on the folding mechanism, a frame on the top surface of the mounting plate, a lifting frame and a lifting drive mechanism for driving the lifting frame to move on the side of the frame, a feed frame and a feed drive mechanism for driving the feed frame to move on the lifting frame, a boring drive component on the feed frame, and a boring cutter at the output end of the boring drive component.

[0015] Furthermore, the movable frame includes a lower support frame, the bottom of which is provided with several casters, a vertical support frame is provided on the upper part of the lower support frame near one side, and the folding mechanism is provided on the top of the vertical support frame.

[0016] Furthermore, the folding mechanism includes a folding support frame, which is rotatably mounted on top of the vertical support frame. A flipping drive is provided between the vertical support frame and the folding support frame, and a positioning component is provided on the outer side of the vertical support frame and the folding support frame.

[0017] Furthermore, the top of the vertical support frame is rotatably connected to a connecting plate via a pivot, and the other end of the connecting plate is fixedly connected to the folding support frame.

[0018] Furthermore, the positioning component includes a positioning plate, one side of which is disposed on the folding support frame, and the other side of which is disposed on the rotating shaft. The bottom of the positioning plate is configured as an arc-shaped positioning part, and the arc-shaped positioning part is provided with a plurality of positioning holes. The vertical support frame is provided with a locking hole. After the folding support frame is folded into place, one of the positioning holes is aligned with the locking hole and locked in place by a locking member.

[0019] Furthermore, the lifting drive mechanism includes a lead screw rotatably mounted on the side of the frame, a lifting drive component for driving the lead screw to rotate is mounted above the frame, a lead screw nut is threaded onto the lead screw, and the lifting frame is connected to the lead screw nut.

[0020] Furthermore, a first slide rail is provided on the side of the frame, and a first slider that matches the first slide rail is provided on the lifting frame.

[0021] Furthermore, a protective cover is provided above the frame, and the lifting drive component is located inside the protective cover.

[0022] Furthermore, the feed drive mechanism includes a feed drive component mounted on the lifting frame, the output end of the feed drive component is provided with a gear, and the side of the feed frame is provided with a rack that meshes with the gear.

[0023] Furthermore, a second slide rail is provided on the outer wall of the feed frame, and a second slider that matches the second slide rail is provided on the lifting frame.

[0024] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0025] This invention achieves true "portability" by incorporating a movable frame that allows the device to be easily pushed within tunnels. A folding mechanism allows it to be folded into a vertical storage position, significantly reducing the overall thickness and footprint of the device during movement, resulting in a compact transport form that allows it to pass smoothly through narrow tunnels and be easily stored in a safe corner, completely solving the problem of large equipment blocking passageways. Furthermore, the use of positioning components and a flipping drive ensures sufficient rigidity and stability to support the boring reaction force in the horizontal working position, fundamentally guaranteeing the dimensional accuracy and surface quality of the boring, with processing capabilities far exceeding those of handheld tools.

[0035] like Figure 1-7 As shown, a portable boring device for mining machinery includes a movable frame. A folding mechanism is installed on the top of the movable frame, and a mounting plate 8 is bolted to the folding mechanism. A frame 9 is connected to the top surface of the mounting plate 8. A lifting frame 13 and a lifting drive mechanism for driving the lifting frame 13 are provided on the side of the frame 9. A feed frame 18 and a feed drive mechanism for driving the feed frame 18 are provided on the lifting frame 13. A boring drive component 22 is provided on the feed frame 18, and a boring cutter 23 is installed at the output end of the boring drive component 22. The boring drive component 22 can be a motor, which can be purchased.

[0036] like Figure 3 As shown, the movable frame includes a lower support frame 1, four casters 2 with brake devices are installed at the bottom of the lower support frame 1, a vertical support frame 3 is vertically connected to the upper part of the lower support frame 1 near the left side, and the folding mechanism is installed at the top of the vertical support frame 3.

[0037] The folding mechanism includes a folding support frame 4. The top of the vertical support frame 3 is rotatably connected to a connecting plate 25 via a pivot. The other end of the connecting plate 25 is fixedly connected to the folding support frame 4 via bolts, so that the folding support frame 4 can rotate relative to the vertical support frame 3. Two flipping drive components 5 are installed between the vertical support frame 3 and the folding support frame 4. The flipping drive components 5 can be existing components such as hydraulic cylinders or electric push rods. Positioning components are installed on both the front and rear sides of the vertical support frame 3 and the folding support frame 4.

[0038] The positioning assembly includes a positioning plate 6. One side of the positioning plate 6 is bolted to the folding support frame 4, and the other side of the positioning plate 6 is mounted on the rotating shaft. The bottom of the positioning plate 6 is configured as an arc-shaped positioning part, on which three positioning holes 601 are formed. The vertical support frame 3 has a locking hole. After the folding support frame 4 is folded into place, one of the positioning holes 601 aligns with the locking hole and is locked in place by a locking member 7. The locking member 7 can be a bolt, which passes through the positioning hole 601 and is threaded into the locking hole. Specifically, as shown... Figure 1-2 As shown, when the folding support frame 4 is in a horizontal position, the leftmost positioning hole 601 and the locking hole are connected by the locking element 7; when the folding support frame 4 is in a vertical position, the rightmost positioning hole 601 and the locking hole are connected by the locking element 7.

[0039] like Figure 5 As shown, the lifting drive mechanism includes a lead screw 11 rotatably mounted on the side of the frame 9 via bearings. A lifting drive component 10 for driving the lead screw 11 to rotate is mounted above the frame 9. A lead screw nut 12 is threaded onto the lead screw 11, and the lifting frame 13 is connected to the lead screw nut 12. A first slide rail 15 is provided on the side of the frame 9, and a first slider 14 matching the first slide rail 15 is provided on the lifting frame 13. One end of the first slider 14 is triangular, and the corresponding cross-section of the first slide rail 15 also has a triangular groove. By improving the shape of the first slide rail 15 and the first slider 14, the first slide rail 15 and the first slider 14 have both guiding functions and prevent the lead screw nut 12 and the lifting frame 13 from rotating with the lead screw 11. The triangular structure also prevents the lifting frame 13 from moving to the right, ensuring that the lifting frame 13 always moves vertically without deviation. The lifting drive component 10 can be a motor with a speed reducer, and this lifting drive component 10 can be purchased.

[0040] When in operation, the lifting drive unit 10 is activated, which drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the lead screw nut 12 to rise or fall vertically, thereby driving the lifting frame 13 to rise or fall vertically to adjust the height.

[0041] In addition, a protective cover 24 is installed above the frame 9, and the lifting drive component 10 is disposed inside the protective cover 24; the protective cover 24 protects the lifting drive component 10 from impacts.

[0042] like Figure 6-7As shown, the feed drive mechanism includes a feed drive component 16 mounted on the lifting frame 13. A gear 17 is mounted on the output shaft of the feed drive component 16, and a rack 19 meshing with the gear 17 is mounted on the side of the feed frame 18. The feed frame 18 passes through a channel in the center of the lifting frame 13, and a groove is provided in the channel for the rack 19 to pass through. A protective shell is also installed on the outside of the lifting frame 13 to protect the gear 17. The feed drive component 16 can be a motor with a speed reducer, and this feed drive component 16 can be purchased.

[0043] The feed frame 18 is equipped with a second slide rail 21 at each of its four edges. The second slide rail 21 is V-shaped. The lifting frame 13 is equipped with a second slider 20 at each of its four corners that matches the second slide rail 21. The cross-section of the second slider 20 matches the V-shaped structure. The second slider 20 moves along the second slide rail 21 to ensure stable feeding of the feed frame 18. The V-shaped structure can effectively decompose the force and improve the stability of the movement.

[0044] During operation, the feed drive 16 is activated, which drives the gear 17 to rotate. The rotation of the gear 17 drives the rack 19 to move in the front-back direction, thereby driving the feed frame 18 to move in the front-back direction.

[0045] The working process of this utility model is as follows:

[0046] First, push the movable frame to the working position and lock its position using the brake device on the caster wheel 2. Then, start the lifting drive 10, which drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the lead screw nut 12 to rise or fall vertically, thereby driving the lifting frame 13 to rise or fall vertically to adjust the height of the boring tool 23. Finally, the boring drive 22 drives the boring tool 23 to rotate for boring operations. At the same time, start the feed drive 16, which drives the gear 17 to rotate. The rotation of the gear 17 drives the rack 19 to move forward, thereby driving the feed frame 18 to move forward.

[0047] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
