Description

Technical Field

[0001] This utility model relates to the field of steel cable anchorage removal technology, specifically to an inclined anchor shearing device and equipment. Background Technology

[0002] During coal mining, anchor cables are the main components of coal mine roadway support. Anchor cables are usually fixed in the surrounding rock of the roadway by special locking devices. Their function is to tightly connect the surrounding rock of the roadway with the support structure through prestressing tension, thereby enhancing the overall load-bearing capacity and stability of the roadway.

[0003] However, in practical applications, after the anchor cable is connected by the locking device, its end often appears in a messy state. Especially when it is necessary to replace or adjust the anchor cable, conventional anchor removal tools often have difficulty effectively approaching the locking device position, which not only prolongs the operation time and increases the labor intensity, but may also cause unnecessary damage to the roadway support structure, thereby affecting the overall safety of the mine. Utility Model Content

[0004] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0005] During the installation of anchor cables, a certain amount of prestress is usually applied to ensure a tight bond between the anchor cable and the surrounding rock of the roadway. However, after installation, as the internal stress of the anchor cable is gradually released, its ends may become disordered due to the loss of their original tension constraint. Furthermore, during installation and use, the anchor cable may undergo elastic deformation due to external forces. This deformation may also lead to changes in the overall length of the anchor cable, causing its ends to bend, twist, or exhibit other complex shapes, resulting in a chaotic appearance.

[0006] When it's necessary to adjust anchor cable tension based on roadway deformation or mining plans, or even replace the entire anchor cable system, the chaotic state of the end cables becomes a thorny problem. Traditional anchor removal tools, such as manual or pneumatic anchor removers, often struggle to effectively approach the locking device when the anchor cable ends are messy. They may be unable to operate due to space constraints or misalignment with the locking device caused by the cable ends, resulting in low anchor removal efficiency and significantly extended operation time.

[0007] Therefore, embodiments of this utility model provide an inclined anchor shearing device, which includes a shearing frame and a shearing assembly. The shearing frame includes a fitting part, a misalignment part, and a shearing cavity. The fitting part is used to fit the mounting surface of the anchor. The fitting part and the misalignment part are connected. The straight line of the extension direction of the fitting part intersects the straight line of the extension direction of the misalignment part. The shearing cavity extends through the fitting part and the misalignment part in a direction perpendicular to the mounting surface. An opening and a guide groove are provided on the side of the shearing cavity. The opening is used for the anchor to enter and exit the shearing cavity. The shearing assembly includes a cutter and a driver. The driver is disposed on the misalignment part. The cutter is drivenly connected to the driver. The cutter is slidably disposed in the guide groove so that the cutter shears the anchor in the shearing cavity.

[0008] In summary, the inclined anchor shearing device provided by this utility model embodiment can solve the problem of end anchor cable interference encountered during anchor removal, and improve the convenience and safety of operation.

[0009] In addition, this utility model embodiment also provides an inclined anchor shearing device.

[0010] In some embodiments, the shearing assembly further includes a transmission rod rotatably connected to the shearing frame, with a cutter and a driver connected to each end of the transmission rod.

[0011] In some embodiments, there are two cutters and two transmission rods. The two cutters are respectively located on both sides of the shearing chamber, and the transmission rods are arranged in a one-to-one correspondence with the cutters. The two transmission rods are correspondingly connected to the two ends of the driver.

[0012] In some embodiments, the shearing assembly further includes an elastic element, the two ends of which are respectively connected to the shearing frame and the transmission rod.

[0013] In some embodiments, the cutting tool has a tool shank, which includes a first section and a second section connected to each other. The first section is movably disposed within the guide groove and has a sliding hole therein. One end of the second section is slidably disposed within the sliding hole, and the other end of the second section is connected to the transmission rod.

[0014] In some embodiments, the transmission rod is provided with a slide groove, and the second section of the cutter is disposed in the slide groove. During the rotation of the transmission rod, the second section can move within the slide groove.

[0015] In some embodiments, the transmission rod has an active arm and a driven arm, the length of the active arm being greater than the length of the driven arm, the active arm being connected to the output end of the driver, and the driven arm being connected to the second section of the cutter.

[0016] In some embodiments, the tool includes a shearing head connected to the tool holder, the shearing head having a cutting angle of 30° to 60°.

[0017] In some embodiments, the actuator is configured as a booster cylinder, and the hydraulic medium of the booster cylinder is configured as an emulsion.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown 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 4As shown, this utility model embodiment provides an inclined anchor shearing device, which includes a shearing frame 10 and a shearing assembly 20. The shearing frame 10 includes a fitting part 11 and a misalignment part 12. The fitting part 11 is used to fit the mounting surface of the anchor. The fitting part 11 and the misalignment part 12 are connected. The straight line of the extension direction of the fitting part 11 intersects the straight line of the extension direction of the misalignment part 12. A shearing cavity 13 is provided through the fitting part 11. The shearing cavity 13 extends in a direction perpendicular to the mounting surface. An opening 131 and a guide groove 14 are provided on the side of the shearing cavity 13. The opening 131 is used for the anchor to enter and exit the shearing cavity 13. The shearing assembly 20 includes a cutter 21 and a driver 22. The cutter 21 is connected to the driver 22. The cutter 21 is slidably disposed in the guide groove 14 so that the cutter 21 cuts the anchor in the shearing cavity 13.

[0028] Specifically, the fitting part 11 can be firmly attached to the mounting surface of the anchor, providing a solid foundation for subsequent shearing operations. The extension direction of the misaligned part 12 is not consistent with that of the fitting part 11, but rather presents an interlaced state. This allows the misaligned part 12 to effectively avoid potentially messy anchor cables at the end of the anchor during shearing, thus preventing these anchor cables from interfering with the normal removal process of the anchor. Furthermore, the shearing cavity 13 extends perpendicular to the mounting surface, ensuring that the cutter 21 can proceed along the most direct and effective path during shearing. Simultaneously, the opening 131 on the side of the shearing cavity 13 allows the anchor to be easily fed into or out of the shearing cavity 13, while the guide groove 14 ensures that the cutter 21 maintains the correct orientation during sliding, thereby achieving precise and efficient shearing.

[0029] In summary, the inclined anchor shearing device provided by this utility model embodiment can solve the problem of end anchor cable interference encountered during anchor removal, and improve the convenience and safety of operation.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the shearing assembly 20 further includes a transmission rod 23, which is rotatably connected to the shearing frame 10. The two ends of the transmission rod 23 are respectively connected to the cutter 21 and the driver 22. During its rotation relative to the shearing frame 10, the transmission rod 23 cleverly amplifies the force applied by the driver 22 using its lever principle. This not only allows the cutter 21 to obtain greater shearing force when shearing the anchor, but also significantly improves shearing efficiency and shortens operation time.

[0031] like Figure 4As shown, in some embodiments, two cutters 21 and two transmission rods 23 are provided. The two cutters 21 are respectively located on both sides of the shearing chamber 13, and the transmission rods 23 are arranged in a one-to-one correspondence with the cutters 21. The two transmission rods 23 are connected to the two ends of the driver 22, so that the cutter 21 can be subjected to more balanced force when shearing the anchor, avoiding the risk of operational instability or damage caused by unilateral force, and improving the accuracy and reliability of the shearing process. At the same time, the cooperative work of the two cutters 21 also significantly shortens the shearing time and improves work efficiency.

[0032] Specifically, the driver 22 has a fixed end 221 and an output end 222. One of the two transmission rods 23 is connected to the fixed end 221 of the driver 22, and the other of the two transmission rods 23 is connected to the output end 222 of the driver 22. When the driver 22 starts working, its output end 222 gradually extends. During this process, the two transmission rods 23 rotate relative to the shearing frame 10, thereby driving the two cutters 21 to move towards each other within the shearing chamber 13. This not only ensures that the cutters 21 can accurately act on the anchor, but also greatly improves the accuracy and reliability of the shearing process. At the same time, due to the coordinated work of the two cutters 21, the shearing time is significantly shortened, and the working efficiency is thus greatly improved.

[0033] Once the anchor shearing is complete, the output end 222 of the driver 22 will retract until it returns to the position of the fixed end 221. During this process, the two transmission rods 23 will rotate in opposite directions relative to the shearing frame 10, thereby driving the two cutters 21 to move in opposite directions. This not only facilitates the removal of the anchor from the shearing chamber 13, but also makes full preparation for the next shearing operation.

[0034] Furthermore, the shearing assembly 20 also includes an elastic element 24, with both ends of the elastic element 24 connected to the shearing frame 10 and the transmission rod 23 respectively. This not only ensures that the transmission rod 23 can rotate more flexibly when subjected to force, but also effectively absorbs the impact and vibration generated during the shearing process through the elastic deformation characteristics of the elastic element 24.

[0035] In this embodiment, the elastic element 24 can be configured as a spring, which is sleeved on the cutter 21, with its two ends corresponding to the shearing frame 10 and the transmission rod 23. When faced with anchors of different sizes, shapes, and materials, the spring can automatically adjust the relative position between the transmission rod 23 and the cutter 21 through its elastic deformation, thereby ensuring that the cutter 21 can always fit tightly and accurately against the anchor, achieving efficient and precise shearing. This adaptive capability greatly improves the versatility and practicality of the shearing assembly 20.

[0036] Furthermore, during the shearing process, the spring can absorb some of the impact force, reducing the burden on the operator's hands and making the operation easier and more comfortable. At the same time, after the anchor shearing is completed, the elastic restoring force of the spring can also help the transmission rod 23 and the cutter 21 quickly return to their initial positions, preparing for the next shearing, thereby improving work efficiency.

[0037] like Figure 4 As shown, in some embodiments, the cutter 21 has a cutter shank 211, which includes a first segment 2111 and a second segment 2112 connected together. The first segment 2111 is movably inserted into the guide groove 14 and has a sliding hole 2113. One end of the second segment 2112 is slidably disposed in the sliding hole 2113, and the other end of the second segment 2112 is connected to the transmission rod 23. That is, during the rotation of the transmission rod 23, because the connection between the second segment 2112 and the transmission rod 23 is flexible, the cutter 21 can always receive the force applied by the transmission rod 23 and reciprocate along the guide groove 14, which not only ensures the continuity and stability of the shearing operation but also significantly improves the shearing efficiency.

[0038] Furthermore, the transmission rod 23 is provided with a groove, and the second section 2112 of the cutter 21 is located within the groove. During the rotation of the transmission rod 23, the second section 2112 can move within the groove. As the distance between the transmission rod 23 and the shearing frame 10 changes during the rotation of the transmission rod 23, the second section 2112 of the cutter 21 can move accordingly within the groove, thereby ensuring a continuous connection between the cutter 21 and the transmission rod 23. This design not only improves the motion accuracy and stability of the cutter 21, but also allows the cutter 21 to better adapt to various forces and motion changes generated during the rotation of the transmission rod 23, ensuring stable power transmission and smooth shearing operations.

[0039] In some embodiments, the transmission rod 23 has an active arm 231 and a driven arm 232. The length of the active arm 231 is greater than the length of the driven arm 232. The active arm 231 is connected to the output end 222 of the driver 22, and the driven arm 232 is connected to the second section 2112 of the cutter 21. This allows the transmission rod 23 to generate a larger torque under the drive of the output end 222 of the driver 22, providing sufficient power support for the shearing operation.

[0040] Furthermore, the length difference between the driving arm 231 and the driven arm 232 can reduce the vibration and noise of the transmission rod 23 during rotation. Because the driving arm 231 is longer, it can absorb and release more impact energy, thereby reducing the vibration of the transmission rod 23 during rotation. The shorter driven arm 232 further reduces the noise generated by the cutter 21 during shearing.

[0041] In some embodiments, the cutting tool 21 includes a shearing head 212 connected to the cutting shank 211. The cutting angle of the shearing head 212 is set to 30° to 60°, which ensures that the cutting tool 21 has sufficient shearing force during the shearing process, while also reducing friction and resistance and improving shearing efficiency. In this embodiment, the cutting angle of the shearing head 212 is set to 30°.

[0042] In some embodiments, the actuator 22 is configured as a booster cylinder, and the hydraulic medium of the booster cylinder is configured as an emulsion. The emulsion is a mixture of water and an emulsifier, possessing good lubricity, cooling properties, and corrosion resistance, effectively reducing environmental pollution while ensuring stable operation of the hydraulic system. Furthermore, the emulsion offers advantages such as low cost, easy availability, and recyclability, further enhancing the environmental and energy-saving performance of this embodiment.

[0043] In addition, one embodiment of this utility model provides an inclined anchor shearing device, which includes a robotic arm and the anchor dismantling device provided in the above embodiment, with the anchor dismantling device located at the end of the robotic arm. Specifically, the robotic arm in this inclined anchor shearing device can flexibly adjust the position and posture of its end according to a preset program or operator's instructions, thereby ensuring that the inclined anchor shearing device can accurately reach the position of the anchor to be dismantled.

[0044] The inclined anchor shearing device provided in the above embodiments is cleverly mounted on the end of a robotic arm, allowing it to move with the robotic arm without manual handling or position adjustment, greatly improving the efficiency of the dismantling operation. At the same time, the high efficiency and reliability of the inclined anchor shearing device itself are fully utilized, enabling rapid and accurate completion of anchor dismantling tasks.
