[0001] This invention relates to the field of anchor dismantling technology, and more specifically to an anchor unloading device and equipment. Background Technology

[0002] In mineral extraction, especially in coal mine tunneling, anchors are widely used as a fixing and support structure to reinforce roadway walls and working faces. However, as mining operations continue, existing anchors need to be removed or replaced. Since anchors are usually tightly fixed to the roadway walls or working faces, dismantling tools cannot fully access them, resulting in partial severing rather than complete removal. This not only increases the difficulty of dismantling but may also leave anchor residue on the roadway walls or working faces, creating safety hazards. Summary of the Invention

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 4 As shown, this embodiment of the invention provides an anchor removal device 100, which includes a base frame 10, an anchor seat 20, a cutter 30, and a power assembly 40. The anchor seat 20 and the cutter 30 are disposed opposite to each other on the base frame 10, and the cutter 30 is movable relative to the anchor seat 20. The anchor seat 20 is used to position the anchor. The power assembly 40 includes a push cylinder 41 and a transmission rod 42. The push cylinder 41 is disposed on the base frame 10, and the transmission rod 42 is rotatably disposed on the base frame 10. One end of the transmission rod 42 abuts against the cutter 30, and the other end of the transmission rod 42 abuts against the push cylinder 41. An elastic element 43 is provided between the cutter 30 and the base frame 10. The cutter 30 and the anchor seat 20 are both located above the hydraulic cylinder, thereby allowing the anchor to be cut against the roadway wall or the working face, avoiding disassembly difficulties due to limited operating space, and helping to improve the speed and accuracy of disassembly operations.

[0028] In this embodiment, the base frame 10 serves as the supporting structure for the entire device, bearing other components and ensuring the stability and reliability of the entire anchor removal operation. The anchor seat 20 is used to precisely position the anchor to be cut, ensuring that the cutter 30 can accurately act on the target position of the anchor. The power assembly 40 is the component that drives the movement of the cutter 30. The push cylinder 41 is mounted on the base frame 10 and provides the necessary force. The transmission rod 42 is rotatably mounted on the base frame 10, amplifying the force applied by the push cylinder 41, allowing the force of the push cylinder 41 to be transmitted to the cutter 30 more efficiently, driving it to perform the anchor cutting operation. Furthermore, both the cutter 30 and the anchor seat 20 are located above the push cylinder 41 and at the top of the base frame 10, thus maintaining contact with the working surface even in situations where space is limited, such as on the tunnel wall or excavation face. This effectively reduces disassembly difficulties caused by limited operating space, further improving the speed and accuracy of the disassembly operation.

[0029] Furthermore, as the cutter 30 moves toward the anchor 20, it gradually applies force to the elastic element 43, causing the elastic element 43 to deform. After the anchor is cut, the deformation-restoring force of the elastic element 43 automatically pushes the cutter 30 back to its initial position. In the initial position, the cutter 30 is separated from the anchor 20, and the anchor to be cut can be accommodated between the cutter 30 and the anchor 20. The cutter 30 also has a cutting position, where it engages with the anchor 20.

[0030] In summary, the anchor removal device 100 provided in this embodiment of the invention not only solves the problem of difficult operation in a narrow space and reduces the difficulty of operation and safety risks by setting the cutter 30 and the anchor seat 20 above the base frame 10, and amplifying the force of the push cylinder 41 through the transmission rod 42 and applying it to the cutter 30, but also improves work efficiency.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the transmission rod 42 has a rotating portion 421 and a first abutting section 422 and a second abutting section 423 located opposite each other on both sides of the rotating portion 421. The first abutting section 422 abuts against the cutter 30, and the second abutting section 423 abuts against the output end 411 of the push cylinder 41. Both the first abutting section 422 and the second abutting section 423 are provided with arc-shaped abutting surfaces 424. That is, both the first abutting section 422 and the second abutting section 423 can abut against the cutter 30 and the output end 411 of the push cylinder 41 respectively through the arc-shaped abutting surfaces 424. Compared with a fixed connection, this provides greater freedom and makes the power transmission smoother and more efficient in transmitting force.

[0032] Specifically, the first contact section 422 adopts an arc-shaped contact surface 424, which ensures that the tool 30 can stably receive the pushing force from the transmission rod 42. This not only increases the contact area with the tool 30 and improves the stability of the connection, but more importantly, the smooth arc transition effectively disperses the impact force during power transmission, allowing the tool 30 to start and run more smoothly when receiving the pushing force. The second contact section 423, also adopting an arc-shaped contact surface 424, allows it to connect more tightly and stably with the output end 411 of the push cylinder 41. Furthermore, the arc-shaped structure effectively absorbs the thrust from the push cylinder 41 and converts it into the rotational power of the transmission rod 42. In this process, the arc-shaped contact surface 424 not only improves the smoothness of power transmission but also effectively reduces vibration and noise caused by direct impact, further extending the service life of the transmission rod 42.

[0033] In addition, the first contact section 422 and the second contact section 423 adopt the design of arc-shaped contact surface 424, which provides greater freedom for the transmission rod 42. This not only allows the transmission rod 42 to better adapt to various complex working conditions and changes during power transmission, but also improves the flexibility and reliability of the entire transmission process.

[0034] Furthermore, the first abutment section 422, the rotating part 421, and the second abutment section 423 are connected in a U-shape, which can change the direction of the pushing force of the push cylinder 41, making the overall structure more compact and facilitating the placement of the push cylinder 41 below the base frame 10. This avoids the push cylinder 41 being too close to the roadway wall or the working face, which could affect the cutting and disassembly of the anchor. Specifically, in related designs, the push cylinder 41 is often placed directly above or to the side of the cutter 30, which not only occupies a large amount of space but may also affect the cutting efficiency due to limited operating space. However, by adopting the U-shaped transmission rod 42, the push cylinder 41 can be cleverly placed below the base frame 10, and the thrust can be transmitted to the cutter 30 through the U-shaped path of the transmission rod 42. This design not only saves space but also avoids the push cylinder 41 being directly close to the roadway wall or the working face, thereby reducing the operational difficulties and safety risks caused by limited space.

[0035] like Figure 1 , Figure 2 , Figure 4 As shown, in some embodiments, the base frame 10 includes a first slide rail 111 and a second slide rail 112 arranged opposite to each other. Both the first slide rail 111 and the second slide rail 112 are provided with a slide groove 113. The cutter 30 has a slider 31 that cooperates with the slide groove 113, and the elastic element 43 is provided in the slide groove 113.

[0036] Specifically, the first slide rail 111 and the second slide rail 112 are disposed opposite to each other on both sides of the cutter 30. The cutter 30 is T-shaped, and the slider 31 on the cutter 30 is correspondingly slidably disposed within the first slide rail 111 and the second slide rail 112, which can limit the movement direction of the cutter 30. Two elastic elements 43 can be provided, correspondingly disposed within the first slide rail 111 and the second slide rail 112. One end of the elastic element 43 is connected to the inner wall of the slide groove 113, and the other end of the elastic element 43 is connected to the slider 31, with the elastic element 43 located between the slider 31 and the anchor 20. In this embodiment, the elastic element 43 is a spring.

[0037] Furthermore, the base frame 10 includes two U-shaped frames 12 arranged side by side. Each U-shaped frame 12 has a first mounting post 121, a second mounting post 122, and a third mounting post 123. The first mounting post 121 and the third mounting post 123 are arranged opposite to each other, and the second mounting post 122 is located between the first mounting post 121 and the third mounting post 123. A first slide rail 111 and a second slide rail 112 are correspondingly arranged with the two U-shaped frames 12. The two ends of the first slide rail 111 are correspondingly connected to the first mounting post 121 and the second mounting post 122 of one of the two U-shaped frames 12, and the two ends of the second slide rail 112 are correspondingly connected to the first mounting post 121 and the second mounting post 122 of the other of the two U-shaped frames 12.

[0038] Furthermore, the base frame 10 also includes a rotating shaft 124, the U-shaped frame 12 is provided with a first hole 125, the rotating part 421 is provided with a second hole 425, and the rotating shaft 124 passes through the first hole 125 and the second hole 425, thereby enabling the rotation of the transmission rod 42.

[0039] like Figure 2 As shown, in some embodiments, the tool 30 has a cutting head 32 with a cutting angle of 30° to 60°, which not only ensures cutting efficiency but also guarantees the service life of the tool 30. In this embodiment, the cutting angle of the cutting head 32 is set to 45°, and the cutting head 32 is pointed. In this embodiment, the tool 30 also includes a tool shank 33, with the cutting head 32 located at one end of the tool shank 33 and the slider 31 located at the other end of the tool shank 33.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the base frame 10 further includes a fixed seat 13 and a fixed ring 14. The push cylinder 41 is mounted on the fixed seat 13, and the fixed ring 14 is connected to the fixed seat 13. The fixed ring 14 is sleeved on the outside of the push cylinder 41, thereby achieving a stable fixation of the push cylinder 41.

[0041] Specifically, the cylinder body of the push cylinder 41 can be fixed to the fixed seat 13 by a threaded structure, and the fixing ring 14 can be sleeved on the cylinder body of the push cylinder 41, thereby realizing the fixation of the push cylinder 41. As shown in the figure, the cylinder body of the push cylinder 41 can be divided into a left side and a right side. The fixed seat 13 is fixed to the right side of the cylinder body, and the fixing ring 14 is sleeved on the left side of the cylinder body.

[0042] Furthermore, the fixing base 13 includes a fixing plate 131 and two extending claws 132, which extend from the fixing plate 131 in the same direction. The two extending claws 132 are respectively connected to the third mounting posts 123 of the two U-shaped frames 12, and the fixing ring 14 is connected to the U-shaped frame 12, thereby fixing the cylinder body of the pushing cylinder 41 to the anchor seat 20. In this embodiment, the fixing ring 14 is located between the second mounting post 122 and the third mounting post 123 of the U-shaped frame 12.

[0043] In this embodiment, the push cylinder 41 is configured as a hydraulic cylinder, and the hydraulic medium of the hydraulic cylinder is configured as an emulsion. The emulsion has good lubricity, cooling, and rust prevention properties, which can effectively reduce the frictional resistance of the hydraulic cylinder during operation, improve transmission efficiency, and reduce wear and corrosion of the hydraulic cylinder and hydraulic system. Furthermore, the emulsion also has good stability, maintaining its performance stability over a relatively long period, thereby ensuring the continuous and reliable operation of the hydraulic cylinder. Of course, in some embodiments, the push cylinder 41 may also be configured as a pneumatic cylinder.

[0044] like Figure 4 As shown, in some embodiments, the base frame 10 further includes a mounting base 15. One of the mounting base 15 and the anchor seat 20 is provided with a mounting groove 151, and the other of the mounting base 15 and the anchor seat 20 is provided with a locking post 21. The locking post 21 is detachably installed into the mounting groove 151, thereby enabling quick replacement of the anchor seat 20. The anchor seat 20 can be replaced according to the type of anchor, thus expanding the applicability of the anchor removal device 100. The mounting groove 151 is provided on the mounting base 15, and the locking post 21 is correspondingly provided on the anchor seat 20. Both ends of the mounting base 15 are fixed to the third mounting posts 123 of the two U-shaped frames 12, thereby fixing the mounting base 15.

[0045] Furthermore, the mounting base 15 also includes a receiving cavity 152 for accommodating the anchor seat 20, and the external dimensions of the anchor seat 20 are adapted to the receiving cavity 152. A mounting groove 151 is provided on the bottom wall of the receiving cavity 152, thereby allowing the anchor seat 20 to be accommodated within the mounting base 15, improving the connection strength between the anchor seat 20 and the mounting base 15, preventing displacement of the anchor seat 20 due to anchor stress, and thus improving the overall structural strength.

[0046] Optionally, the locking post 21 is T-shaped, and the mounting groove 151 is adapted to the shape of the locking post 21, which not only enhances the connection strength between the anchor 20 and the base frame 10, but also reduces the risk of loosening due to vibration or external impact. Of course, in some embodiments, the locking post 21 can also be set to other shapes, such as an inverted V-shape.

[0047] like Figure 4 As shown, in this embodiment, the anchor seat 20 is provided with an arc-shaped groove 22, which can be used to position the anchor. The mounting base 15 has two inclined surfaces 153, which are correspondingly located on both sides of the mounting groove 151. This facilitates the guidance of the anchor into the arc-shaped groove 22 within the anchor seat 20, simplifying the installation process, reducing operational difficulty, and ensuring that the anchor can smoothly and steadily enter the arc-shaped groove 22 during installation, avoiding damage caused by forceful installation or improper operation. Furthermore, the presence of the inclined surfaces 153 increases the tolerance during installation; even with slight operational deviations, the anchor can be smoothly returned to its position under the guidance of the inclined surfaces 153.

[0048] Furthermore, both the first slide rail 111 and the second slide rail 112 are provided with guide surfaces 114, which are inclined and correspond one-to-one with the inclined surfaces 153. That is to say, the guide surfaces 114 and the inclined surfaces 153 can form a V-shaped guide structure to accurately guide the anchor into the arc-shaped groove 22.

[0049] Furthermore, the inclination angles of the inclined surface 153 and the guide surface 114 can be set to 45° to 60°. This not only provides sufficient guiding force to ensure that the anchor or other related components can move smoothly and accurately along the predetermined path, but also avoids structural instability or operational difficulties caused by excessive inclination angles. In this embodiment, the inclination angles of both the inclined surface 153 and the guide surface 114 are set to 60°.

[0050] In addition, embodiments of the present invention also provide an anchor removal device, which includes a robotic arm and the aforementioned anchor removal device 100, the anchor removal device 100 being mounted on the robotic arm. The robotic arm typically consists of multiple joints, such as rotary joints and translational joints, and can drive the anchor removal device 100 to move flexibly in three-dimensional space. The arc-shaped groove 22 is aligned with the anchor, thereby achieving anchor removal.
