Technical Field
[0001] This invention relates to the field of telescopic basket locking technology, specifically an integrated anchor bolt basket locking robotic arm for underground mining. Background Technology
[0002] In the prior art, Chinese Patent No. CN209308719U discloses a tool for removing anchor bolt locking devices. It mainly includes symmetrically arranged removal plates, a hammer, and a connecting structure, designed to solve the problem of difficulty in removing anchor bolt spherical pads and trays due to deformation caused by high pressure from the roadway roof. This tool uses an arc-shaped plate to hold the spherical pad and utilizes the hammer to achieve rapid removal, featuring simple operation and high efficiency. However, this removal tool still relies on manual operation and striking, which presents problems in complex mining environments such as limited operating space, uneven force control, and safety dependence on personnel experience. Its applicability is particularly limited in high-position, multi-angle anchor bolt locking operations.
[0003] Furthermore, in mine support operations, the locking of anchor bolts typically relies on manual labor or simple mechanical tools, resulting in low efficiency, uneven locking force, high labor intensity, and numerous safety hazards. Especially in the confined, dusty, humid, and explosive environments underground, the use of electric or hydraulically driven equipment is limited, while traditional pneumatic tools often lack sufficient buffering and precise control mechanisms, leading to vibrations, misalignment, or incomplete locking during the locking process, affecting both support effectiveness and operational safety.
[0004] Therefore, there is an urgent need for an integrated device that can adapt to the complex environment of mines and achieve efficient, stable, and multi-angle locking of anchor bolts and baskets, in order to solve the problems of low locking efficiency, poor operational safety, and insufficient equipment adaptability in existing technologies.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This application causes the piston cylinder to push the support spring and the first guide block forward, compressing the support spring and thus buffering and supporting the piston cylinder, improving the stability of the piston cylinder during movement. By setting a piston plate inside the piston cylinder and opening multiple through holes therein, and simultaneously injecting buffer solution into the piston cylinder, the buffer solution flows through the through holes and generates a damping effect when the piston plate moves inside the piston cylinder. This, together with the support spring, buffers and stabilizes the forward movement of the piston cylinder, effectively improving the smoothness of the equipment during the pushing process, preventing the equipment from shaking or deviating due to impact, thereby ensuring the accuracy of the basket locking operation.
[0017] 2. This application causes the first guide block to drive the limit block and the second guide block to rotate, thereby causing the second guide block to drive the universal joint and the connecting shaft to rotate. When the connecting shaft rotates, it drives the first bevel gear to rotate. When the first bevel gear rotates, it drives the second bevel gear to rotate, causing the second bevel gear to drive the vertical shaft and the first gear to rotate. The first gear drives the second and third gears on both sides to rotate. The rotation of the second and third gears drives the fourth and fifth gears to rotate, and at the same time drives the gear ring to rotate. The gear ring drives the turning ring to rotate. When the turning ring rotates, it pushes the flower basket to rotate through the slot, causing the bolts inside the flower basket to rotate relative to each other when the flower basket rotates, thereby locking the flower basket and pulling the steel cable for adjustment.
[0018] 3. This application utilizes the airflow from the ventilation duct to rotate the blades inside the blower, which in turn drives the output shaft to rotate, using wind power as the power source. By employing a blower as the power source, the wind-driven rotating cylinder is connected to the mine ventilation duct, which in turn drives the threaded rod to rotate and move horizontally within the threaded ring, pushing the piston cylinder forward. This achieves a purely pneumatic drive method that eliminates the need for electricity or hydraulic systems, thus meeting the safety requirements of the flammable and explosive environment in mines while reducing equipment energy consumption and maintenance costs.
[0019] 4. The second guide block and the connecting shaft are connected by a universal joint, which allows the bottom shell to be flexibly adjusted according to the position of the basket. It engages with the basket through the groove inside the turning ring, and the rotational power is transmitted to the turning ring through the gear transmission assembly, realizing the basket tightening operation at multiple angles and positions, which improves the applicability and ease of operation of the equipment.

Finally, it drives the fourth gear 22 and the fifth gear 23 to rotate.
[0025] The locking assembly includes a rotating ring 25 and a gear ring 26. An annular groove 24 is provided inside the bottom shell 2.

A positioning plate 38 is fixedly connected to the top of the top cover 29. Positioning holes 39 are opened at both ends of the positioning plate 38. The positioning pin 34 is adapted to the two positioning holes 39 respectively. The sliding sleeve 33 is positioned by inserting the positioning pin 34 into the positioning hole 39.
[0026] The drive assembly includes a rotating cylinder 41 and a threaded rod 42. The rotating cylinder 41 is rotatably connected to the inside of a fixed cylinder 40. The threaded rod 42 is disposed inside the rotating cylinder 41. Limiting strips 43 are fixedly connected to both sides of the inside of the fixed cylinder 40. A threaded ring 50 is fixedly connected to the front end of the inside of the fixed cylinder 40. The threaded rod 42 passes through the threaded ring 50 and is threadedly connected to the threaded ring 50. Guide grooves 44 are provided on both sides of the threaded rod 42. The two limiting strips 43 are slidably connected to the two guide grooves 44 and are adapted to the two guide grooves 44. A connecting plate 49 is fixedly connected to the front end of the threaded rod 42. The connecting plate 49 is fixedly connected to the rear end of the piston cylinder 3. The movement of the threaded rod 42 drives the connecting plate 49 to move. The piston cylinder 3 is moved by the movement of the piston cylinder 40. A guide sleeve 51 is fixedly connected to the bottom of the fixed cylinder 40. A moving block 45 is slidably connected inside the guide sleeve 51. A crossbar 46 is fixedly connected to the front end of the moving block 45. The crossbar 46 passes through the front wall of the guide groove 44 and is slidably connected to the guide sleeve 51. A connecting block 47 is fixedly connected to the rear end of the bottom of the piston cylinder 3. The front end of the crossbar 46 is fixedly connected to the connecting block 47. A blower 48 is fixedly connected to the rear end of the fixed cylinder 40. The output end of the blower 48 passes through the fixed cylinder 40 and is rotatably connected to the fixed cylinder 40. The output shaft of the blower 48 is fixedly connected to the rear end of the rotating cylinder 41. The input end of the blower 48 is connected to the mine ventilation duct to limit the movement of the piston cylinder 3.
[0027] In this design, the fixed cylinder 40 is installed near the flower basket, and the blower 48 is connected to the mine ventilation duct. The wind from the duct blows the blades inside the blower 48 to rotate, which in turn drives the output shaft to rotate, using wind power as the power source. By using the blower 48 as the power source, the wind power driven by the mine ventilation duct drives the rotating cylinder 41 to rotate, which in turn drives the threaded rod 42 to rotate and move horizontally within the threaded ring 50, pushing the piston cylinder 3 forward. This achieves a pure pneumatic drive method that does not require electricity or hydraulic systems, which not only meets the safety requirements of the flammable and explosive environment in mines, but also reduces equipment energy consumption and maintenance costs.
[0028] When the flower basket needs to be adjusted, place the bottom shell 2 and the top cover 29 next to the flower basket, aligning the opening of the bottom shell 2 with the flower basket. Place the flower basket inside the bottom shell 2 and inside the turning ring 25, engaging it with the flower basket through the slot 27. Then, the operator manually pushes the blocking ring 31 to rotate. As the blocking ring 31 rotates, it moves the support plate 32 and the sliding sleeve 33, causing the support plate 32 and the sliding sleeve 33 to move the positioning pin 34. This causes the positioning pin 34 to align with the positioning hole 39 at one end of the positioning plate 38. The limit spring 37 pops out, pushing the positioning pin 34 down, allowing the positioning pin 34 to insert into the positioning hole 39 to position the blocking ring 31, locking the flower basket inside the bottom shell 2 to prevent it from detaching. The sliding barrier ring 31 and its matching positioning mechanism, by pushing the barrier ring 31, allow the positioning pin 34 to be inserted into the positioning hole 39, quickly locking the basket inside the bottom shell 2 and preventing it from coming out during tightening. This not only enhances operational safety but also improves work efficiency.
[0029] Turn on the wind turbine 48, causing the wind to drive the output shaft of the wind turbine 48 to rotate, which in turn drives the rotating cylinder 41 to rotate. When the rotating cylinder 41 rotates, the limiting strips 43 on both sides inside limit the guide groove 44, causing the rotating cylinder 41 to drive the threaded rod 42 to rotate synchronously. When the threaded rod 42 rotates, it drives the connecting plate 49 to rotate. At the same time, the threaded ring 50 limits the threaded rod 42, causing the threaded rod 42 to move horizontally during rotation. When the threaded rod 42 rotates and moves, it drives the connecting plate 49 to move, causing the connecting plate 49 to drive the piston cylinder 3 to move. When the piston cylinder 3 moves forward, it moves forward inside the support cylinder 1, causing the piston cylinder 3 and the limiting plate 5 to move relative to each other, thus slowing down the movement of the piston cylinder 3. Fluid flows through multiple through holes, creating a damping effect. This causes the piston cylinder 3 to push the support spring 9 and the first guide block 8 forward, compressing the support spring 9 and thus buffering and supporting the piston cylinder 3. This improves the stability of the piston cylinder 3 during movement. By setting a piston plate 4 inside the piston cylinder 3 and opening multiple through holes therein, and simultaneously filling the piston cylinder 3 with buffer solution, the buffer solution flows through the through holes and generates a damping effect when the piston plate 4 moves inside the piston cylinder 3. This, together with the support spring 9, buffers and stabilizes the forward movement of the piston cylinder 3, effectively improving the smoothness of the equipment during the pushing process and preventing the equipment from shaking or shifting due to impact, thereby ensuring the accuracy of the basket locking operation.
[0030] The first guide block 8 moves the limiting block 10 towards the second guide block 11, causing the limiting block 10 to engage with the second guide block 11, thus connecting the first guide block 8 and the second guide block 11. When the piston cylinder 3 rotates, the piston cylinder 3 drives the limiting plate 5 to rotate, limiting the transmission groove 6, thereby driving the piston plate 4 to rotate. When the piston plate 4 rotates, it drives the slide rod 7 and the first guide block 8 to rotate, causing the first guide block 8 to drive the limiting block 10 and the second guide block 11 to rotate, thus causing the second guide block 11 to drive the universal joint 13 and the connecting shaft 14 to rotate. When the connecting shaft 14 rotates, it drives the first guide block 7 to rotate. When the first bevel gear 16 rotates, it drives the second bevel gear 18 to rotate, which in turn drives the vertical shaft 17 and the first gear 19 to rotate. The first gear 19 then drives the second gear 20 and the third gear 21 on both sides to rotate. The rotation of the second gear 20 and the third gear 21 drives the fourth gear 22 and the fifth gear 23 to rotate, which in turn drives the gear ring 26 to rotate. The gear ring 26 then drives the turning ring 25 to rotate. When the turning ring 25 rotates, it pushes the flower basket to rotate through the slot 27, causing the bolts inside the flower basket to rotate relative to each other, thereby locking the flower basket and pulling the steel cable for adjustment.
[0031] When the base shell 2 moves and aligns with the flower basket, the universal joint 13 rotates to change direction, allowing the base shell 2 to be freely adjusted to fit the positions of multiple nearby flower baskets. This facilitates adjustment. When tightening the flower basket, the user holds the handle 28 to keep the base shell 2 stable. The universal joint 13 connects the second guide block 11 to the connecting shaft 14, allowing the base shell 2 to flexibly adjust its direction according to the flower basket's position. It engages with the flower basket through the slot 27 inside the tightening ring 25, and the rotational power is transmitted to the tightening ring 25 via a gear transmission assembly, enabling multi-angle and multi-position tightening operations for the flower basket, improving the equipment's applicability and ease of operation.
[0032] Example 2: Underground mine protection typically involves laying protective mesh on the top and sides of the tunnel. Multiple steel sheet mats are then used to press the mesh down. Anchor bolts and pallets are installed by drilling holes in the steel sheet mats and then pressed down. Tightening nuts are threaded onto the outside of the anchor bolts and then pressed onto the pallets to secure the mesh. The anchor bolts at the top are generally not cut off. (See attached image.) Figure 18 As shown, this application can tighten the anchor bolts by adding hexagonal threaded sleeves 52. When tightening the clamping nuts installed on the anchor bolts on the isolation net, as shown in the attached diagram... Figure 19 and Figure 20 As shown, the hexagonal threaded sleeve 52 is placed above the tightening ring 25 and fixed in place with bolts. The hexagonal threaded sleeve 52 passes through the anchor rod and is fitted onto the outside of the clamping nut. When the tightening ring 25 rotates, it drives the hexagonal threaded sleeve 52 to rotate. In use, the hexagonal threaded sleeve 52 is fitted onto the end of the anchor rod so that the inner side of the hexagonal threaded sleeve 52 fits onto the clamping nut. When the hexagonal threaded sleeve 52 rotates, it drives the clamping nut to tighten, thus clamping the tray and fixing the isolation net (this description is based on existing technology, and its structure is familiar to mine workers). The driving of the clamping nut demonstrates the multi-functionality of this device.
[0033] Other application scenarios, such as Figure 21 In the tunnel shown, the current method of train operation involves multiple suspension chains connecting the train to a single rail, which then travels along the rail. Lacking rigid support, this can be addressed by utilizing exposed anchor bolts at the top. Several steel rings (the exact number depending on the rail length) can be welded to the lowest point of the anchor bolts and onto the train rail. Figure 2The basket structure shown connects two steel rings. The length and type of the basket are selected based on the distance between the rail and the top of the tunnel. The principle is to make the basket, after connecting the anchor rod and the rail, form a triangular structure with the vertical suspension chain. This can greatly improve the safety of the train and avoid large swaying caused by tunnel wind and mechanical vibration. This device can greatly improve the safety of train operation. In this application scenario, this device can be used for multiple purposes. In narrow tunnel spaces and hot environments, it can greatly improve the operating efficiency of personnel and reduce the need to carry multiple pieces of equipment.
