Detailed Implementation

[0023] 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.

[0024] The following describes a single-cycle anchor bolt support device for mining according to an embodiment of the present invention.

[0025] See Figures 1-6 The single-cycle anchor bolt support device for mining according to this embodiment of the invention includes a frame 1, a drill box assembly 2, a bolt chamber assembly 4, and a loading and unloading assembly 5.

[0026] The drill box assembly 2 is mounted on the frame 1 and is movable relative to the frame 1 along a first direction. The drill box assembly 2 can move along the first direction to achieve automatic feeding. After the drill rod 61 is connected to the drill box assembly 2, the drill box assembly 2 can drive the drill rod 61 to rotate and move along the first direction, thereby enabling drilling operations on the rock wall.

[0027] In this embodiment, the first direction is the generally up-down direction shown in the figure, the second direction is the generally left-right direction shown in the figure, and the third direction is the generally front-back direction shown in the figure.

[0028] The rod storage assembly 4 is mounted on the frame 1. The rod storage assembly 4 has multiple rod position chambers 45 arranged side-by-side. These multiple rod position chambers 45 are movable relative to the frame 1, allowing any one of them to be positioned opposite the drill box assembly 2 in a second direction. The rod position chambers 45 can hold rods, such as drill rods 61, anchor rods 63, and dosing rods. In this embodiment, by arranging multiple rod position chambers 45, one type of rod can be placed in each chamber, thus satisfying all the rods needed for a single cycle. When operation begins, the corresponding rods can be transported to the drill box assembly 2 using the loading / unloading assembly 5 and docked with the assembly. Subsequently, the drill box assembly 2 can drive the drill rod 61 for drilling, or drive the dosing rod to dock with the borehole, then push the dosing cartridge 626 into the borehole, or push the anchor rod 63 into the borehole and further push the dosing cartridge 626 to the bottom of the borehole.

[0029] The loading / unloading assembly 5 is located on the frame 1. The loading / unloading assembly 5 is used to grab rods from the rod position bin 45 or the drill box assembly 2 and move them along the second direction to transport the rods from the rod position bin 45 to the drill box assembly 2, and to transport rods from the drill box assembly 2 to the rod position bin 45. The loading / unloading assembly 5 can be opposite to the drill box assembly 2 in the second direction. Thus, when one of the rod position bins 45 moves to a position opposite to the drill box assembly 2 in the second direction, the loading / unloading assembly 5 can first grab the drill rod 61, anchor rod 63, or dosing rod in the rod position bin 45, and then transport it to the drill box assembly 2, so that the axis of the corresponding rod coincides with the axis of the drill box assembly 2. At this time, the drill box assembly 2 contacts the corresponding rod by moving in the vertical direction. As the drill box assembly 2 rotates, the rod and the drill box assembly 2 can be docked.

[0030] Understandably, the lower part of each rod is equipped with a connecting section, such as a threaded section. When the rod and the drill box assembly 2 align in the first direction, the drive end of the drill box assembly 2 can be provided with a threaded hole. By rotating the drill box assembly 2, the connecting section of the rod can be connected into the threaded hole of the drill box assembly 2 to achieve docking. After docking, the loading / unloading assembly 5 releases the rod and automatically resets to allow for the next loading or unloading action. The connecting section can also be a polygonal structure, with the drill box assembly 2 and the rod fixed by clamping.

[0031] The single-cycle anchor bolt support device for mining in this embodiment of the invention places drill rods 61, anchor bolts 63, and explosive cartridges 626 in multiple bolt position chambers 45 respectively. Subsequently, it can realize automatic loading and unloading, automatic drilling, automatic explosive injection, and automatic anchoring. The processes can be automatically switched. One device can realize continuous automated operation, which is highly practical. It can realize single-cycle fully automatic operation of anchor bolt 63 support in coal mines, reduce labor intensity, and improve the automation level of anchor bolt 63 support operation.

[0032] See Figure 1 In some embodiments, the frame 1 includes a first frame 11 and a second frame 12. The first frame 11 can serve as the base support for the drill box assembly 2. The first frame 11 and the drill box assembly 2 are constructed as a lightweight drilling rig. The second frame 12 can serve as the base support for the rod storage assembly 4 and the loading / unloading assembly 5. The second frame 12, the rod storage assembly 4, and the loading / unloading assembly 5 are constructed as an integrated storage device. The first frame 11 and the second frame 12 can be directly connected to each other, or they can be opposite each other and respectively connected to a base. Specifically, the first frame 11 and the second frame 12 are arranged opposite each other in a second direction. The drill box assembly 2 is connected to the first frame 11 and is located on the side of the first frame 11 adjacent to the second frame 12. The rod storage assembly 4 and the loading / unloading assembly 5 are connected to the second frame 12, and the rod storage assembly 4 is located on the side of the second frame 12 adjacent to the first frame 11.

[0033] In this embodiment, the frames 1 are relatively independent of each other, which reduces interference between them during operation and allows for reasonable planning of the spacing between them, facilitating the arrangement of the bar bin assembly 4, loading and unloading assembly 5, drilling box assembly 2, etc., resulting in better practicality.

[0034] In some embodiments, the mining single-cycle anchor bolt support device further includes a slide assembly 3, which is mounted on the frame 1 and has a mounting portion. The drill box assembly 2 is connected to the mounting portion of the slide assembly 3, and the slide assembly 3 is used to drive the drill box assembly 2 to reciprocate along a first direction. The slide assembly 3 includes at least two guide rods extending in the vertical direction and a sliding seat slidably mounted on the guide rods. The sliding seat has a mounting portion, and the drill box assembly 2 can be fixed on the mounting portion of the sliding seat. A driving component such as a hydraulic cylinder or a lead screw mechanism can be provided between the sliding seat and the frame 1, thereby driving the sliding seat to reciprocate along the guide rods in the vertical direction and stably controlling the feed rate of the drill box assembly 2.

[0035] In some embodiments, the mining single-cycle anchor bolt support device further includes a roof plate assembly 7, which is mounted on the frame 1. The roof plate assembly 7 and the drill box assembly 2 are arranged opposite to each other in a first direction. The roof plate assembly 7 includes a roof plate and a first actuator. The roof plate is located at the upper end of the frame 1, and the first actuator is used to drive the roof plate to reciprocate in the first direction. The first actuator can be a hydraulic cylinder, which can drive the roof plate to move in the vertical direction. Thus, when construction work is carried out, the roof plate can be made to abut against the wall of the roadway, ensuring the overall stability.

[0036] Furthermore, clearance grooves can be provided on the top plate to avoid interference between the top plate and the corresponding anchor bolts 63, drill rods 61, or dosing rods.

[0037] See Figure 3 and Figure 5 In some embodiments, the rod storage assembly 4 includes a rod storage frame 41 and a first drive component. The rod storage frame 41 is connected to the frame 1, and rod storage compartments 45 are disposed on the rod storage frame 41. The rod storage frame 41 is movable relative to the frame 1 in a third direction. The first drive component is connected to the rod storage frame 41 to drive the rod storage frame 41 to move. It is understood that the rod storage frame 41, driven by the first drive component, can move in a third direction to adjust the rod storage compartments 45. For example, when three rod storage compartments 45 are arranged on the rod storage frame 41, drill rods 61, anchor rods 63, and chemical dosing rods are respectively arranged in the three rod storage compartments 45. When drilling is required, the first drive component drives the rod storage frame 41 to move, so that the rod storage compartment 45 with drill rods 61 corresponds to the drill box assembly 2 in the left-right direction for easy material loading. When chemical dosing is required, the first drive component drives the rod storage frame 41 to move, so that the rod storage compartment 45 with chemical dosing rods corresponds to the drill box assembly 2 in the left-right direction for easy material loading. When it is necessary to place the anchor bolt 63, the first driving component drives the rod storage frame 41 to move, so that the rod storage compartment 45 where the anchor bolt 63 is arranged corresponds to the drill box assembly 2 in the left and right directions to facilitate material loading.

[0038] This embodiment allows for flexible adjustment of the type of poles arranged within the pole position chamber 45 according to actual application conditions, resulting in greater flexibility.

[0039] Furthermore, the first driving component includes a third frame 42, a second driver 43 mounted on the third frame 42, and a transmission screw 44. The second driver 43 can be a servo motor. In this embodiment, the first driving component is a relatively independent component, which can ensure the structural stability of the first driving component, facilitate separate procurement and installation, and has good practicality and is easy to maintain. The third frame 42 is connected to the frame 1 and serves as the basic support for the second driver 43, the transmission screw 44, and the rod holder frame 41. The rod holder frame 41 is mounted on the third frame 42. A sliding slot or guide rod can be provided on the third frame 42. The rod holder frame 41 is mounted on the sliding slot or guide rod and can reciprocate relative to the third frame 42 along a third direction. Multiple rod holders 45 are arranged side by side along a third direction. When the rod holder frame 41 moves, the positions of the multiple rod holders 45 can be adjusted to facilitate loading and unloading operations. The lever holder 41 is equipped with a lead screw nut, which is connected to the lead screw 44. The second driver 43 drives the lead screw 44 to rotate so as to move the lever holder 41.

[0040] In this embodiment, there are multiple lever-cell assemblies 4, which are arranged at intervals from each other along the first direction.

[0041] For example, there are two pole storage assemblies 4. The first pole storage assembly 4 is located at the upper end of the second frame 12, and the second pole storage assembly 4 is located at the lower end of the second frame 12. This allows both ends of the pole to be arranged in the pole storage 45, thereby improving stability.

[0042] Of course, the number of pole cell components 4 can also be three or four, which facilitates the optimization of the distance between two adjacent pole cell components 4, improves the matching degree with the length of the pole, and ensures that a pole is arranged in at least two pole cell 45.

[0043] The single-cycle anchor bolt support device for mining in this embodiment also includes a support plate 48, which is connected to the frame 1 and is located on one side of the bolt storage assembly 4 in the first direction. The support plate 48 can support one end of the bolt. The support plate 48 is located at the lower part of the second frame 12. When the bolt is placed in the bolt storage chamber 45, the bolt can be supported by the support plate 48 under its own weight. This allows the bolt storage chamber 45 to only limit and straighten the bolt without providing a large clamping force, reducing the structural complexity of the bolt storage chamber 45 and facilitating the arrangement of the bolt.

[0044] The single-cycle anchor bolt support device for mining in this embodiment also includes a detection component 49, which is used to detect the movement position of multiple bolt holders 45. The detection component 49 can be a displacement sensor, used to detect the movement distance of the bolt holder frame 41, thereby achieving precise positioning of the bolt holders 45, ensuring that the loading and unloading assembly 5 can accurately grab the bolts, and improving practicality.

[0045] In some embodiments, the rod position chamber 45 includes at least a first chamber, a second chamber, and a third chamber. The first chamber contains a rod assembly 62, which includes a rod body 621 and a third actuator 622. The inner cavity of the rod body 621 forms a drug chamber for placing a drug roll 626, and the third actuator 622 is used to push the drug roll 626. The second chamber is used to place drill rods 61, and the third chamber is used to place anchor rods 63. The rod assembly 62 in this embodiment is the drug delivery rod in the above embodiments. In application, the drug roll 626 can be manually placed into the drug chamber, and then the rod assembly 62 is placed in the first chamber. After the rod body 621 is connected to the drill box assembly 2, and the inner cavity of the rod body 621 is connected to the inner cavity of the borehole, the third actuator 622 can be used to push the drug roll 626 into the borehole to achieve automatic drug delivery.

[0046] See Figure 1 , Figure 3 and Figure 4 Furthermore, the rod assembly 62 includes a center seat 623 and a connector 624. The center seat 623 is located at the first end of the rod and can at least partially penetrate into the borehole for positioning, preventing lateral deviation between the inner cavity of the rod body 621 and the borehole during the dosing process, which would prevent the cartridge 626 from being pushed into the borehole. The center seat 623 and the rod body 621 can be connected by a flange, which can also abut against the top wall of the tunnel for positioning and support. The end of the center seat 623 is tapered to facilitate entry into the borehole. The connector 624 is located at the second end of the rod and can have a threaded section on its outer wall for easy connection with the drill box assembly 2. The rod body 621, center seat 623, and connector 624 are coaxially arranged and their inner cavities are interconnected. The connector 624 is used to connect with the drill box assembly 2. The third actuator 622 is a piston located in the inner cavity of the rod body 621, with the dosing chamber located on the side of the piston adjacent to the center seat 623. The cartridge 626 can be fed into the inner cavity of the rod body 621 through the end of the rod body 621 near the tip seat 623. When it is necessary to push the cartridge 626 into the inner cavity of the rod body 621, high-pressure water can be injected into the inner cavity of the rod body 621 by the drill box assembly 2. The high-pressure water can push the piston to move, and then the piston pushes the cartridge 626 to move until the cartridge 626 is pushed out of the rod body 621 and into the borehole.

[0047] The dextrose assembly 62 also includes a fall arrestor 625, which is sleeved on the outside of the dextrose roll 626 inserted into the dextrose cavity. The fall arrestor 625 can be a sleeve with a certain degree of elasticity. Sleeveted on the outside of the dextrose roll 626, the fall arrestor 625 can be pushed into the borehole along with the dextrose roll 626. The fall arrestor 625 can prevent the dextrose roll 626 from sliding in the borehole, and plays a role in temporarily fixing and supporting the dextrose roll 626. Especially for boreholes with downward opening, it can ensure that the dextrose roll 626 is stable in the borehole, which facilitates subsequent processes.

[0048] Furthermore, the rod holder 45 in this embodiment includes a placement groove 46 and a stop 47. A stop 47 is provided on each side of the opening of the placement groove 46, and the distance between two stops 47 is less than the outer diameter of the rod placed in the rod holder 45. The placement groove 46 can be generally U-shaped, and the stop 47 is located at the opening to prevent the rod from falling out of the placement groove 46. The stop 47 can have a certain degree of elasticity. When a rod is placed in, a certain amount of pushing force is applied to the rod, causing the stop 47 to elastically deform and the rod to be placed into the placement groove 46. When the stop 47 returns to its original position, it prevents the rod from falling out of the placement groove 46. Alternatively, the stop 47 can be rotatably connected to the rod holder frame 41, and the stop 47 can be connected to the rod holder frame 41 via a spring or other reset component. When the stop 47 is in its reset state, it can prevent the rod from falling out of the placement groove 46.

[0049] After the loading and unloading assembly 5 grabs the rod, by applying a pushing force to the rod, the rod can be deformed by squeezing the stop part 47 and taken out from the placement groove 46.

[0050] The stop part 47 can be a stop roller, and two stop rollers are respectively provided on both sides of the groove opening of the placement groove 46. The stop rollers can be rubber rollers.

[0051] See Figure 1 , Figure 3 and Figure 6 In some embodiments, the loading and unloading assembly 5 includes a second driving component 51 and a clamping component 52. The second driving component 51 is connected to the frame 1, and the clamping component 52 is connected to the driving end of the second driving component 51. The clamping component 52 is opposite to the drill box assembly 2 in a second direction. The clamping component 52 is used to clamp the rod in the rod position compartment 45, and the second driving component 51 is used to drive the clamping component 52 and the rod to move along the second direction.

[0052] Furthermore, the second driving component 51 includes a fourth driver 511 and a linkage mechanism 512. The linkage mechanism 512 is disposed between the clamping component 52 and the frame 1. The fourth driver 511 is used to drive the linkage mechanism 512 to move the clamping component 52 in the second direction. The fourth driver 511 can be a hydraulic cylinder. The clamping component 52 includes a fourth frame 521, a first gripper 522, a second gripper 523, and a fifth driver 524. The fourth frame 521 is connected to the driving end of the second driving component 51. The first gripper 522 and the second gripper 523 are pivotally connected to the fourth frame 521. The fifth driver 524 is connected to the first gripper 522 and the second gripper 523 to drive the opening and closing of the first gripper 522 and the second gripper 523. The first gripper 522 and the second gripper 523 are configured to form a gripping area. When the first gripper 522 and the second gripper 523 are close to each other, the rod can be gripped. When the first gripper 522 and the second gripper 523 are far apart from each other, the rod can be released.

[0053] The loading and unloading assembly 5 also includes a support frame 513, which can be a vertical beam extending in the vertical direction. A linkage mechanism 512 is located between the support frame 513 and the frame 1. Multiple clamping components 52 are connected to the support frame 513, and the multiple clamping components 52 are arranged at intervals from each other in the first direction. This ensures that the multiple clamping components 52 move synchronously in the second direction. The synchronous action of the multiple clamping components 52 can realize the synchronous clamping or loosening of the rod.

[0054] Mining single-circulation anchor bolt support device, such as Figure 1 As shown, the system mainly includes a drilling rig and an integrated storage unit. The drilling rig includes a first frame 11, a slide assembly, and a drill box assembly. The integrated storage unit includes a second frame 12, a loading and unloading assembly, and a rod storage assembly. The drilling rig and the integrated storage unit are roughly aligned left and right. The integrated storage unit contains a drill rod, a dosing rod loaded with an appropriate amount of explosive cartridges, and an anchor bolt. During anchor bolt support operations, the drill rod, dosing rod, and anchor bolt move automatically to the drilling rig in sequence. The drilling rig then sequentially drives the drill rod, dosing rod, and anchor bolt to complete the drilling, explosive injection, and anchoring operations. After the operation is completed, manual assistance is used to load the explosive cartridges and anchor bolts, allowing for the next anchor bolt support operation. The specific workflow of the single-cycle anchor bolt drilling rig for coal mines is as follows: (1) Preparation: Install anti-fall components on the explosive cartridge and insert it into the explosive rod; then manually assist in placing the drill rod, explosive rod, and anchor rod into the rod position compartment of the upper rod compartment assembly and the lower rod compartment assembly of the integrated storage device in sequence.

[0055] (2) Drilling action: The rod position chambers of the upper rod chamber assembly and the lower rod chamber assembly in the integrated bin device move synchronously, driving the drill rod to the clamping part of the loading and unloading assembly, which is the initial position of the entire working process. The top plate assembly in the drilling machine extends to complete the top contact action. The fifth drive (cylinder) in the clamping part of the loading and unloading assembly retracts, driving the first and second jaws to grip the drill rod; then the fourth drive (cylinder) pushes the linkage mechanism to move, and then the clamping part of the loading and unloading assembly drives the drill rod to move. When the fourth drive extends to the limit, the drill rod in the clamping part moves to the designated position of the drill box assembly in the drilling machine, that is, directly above the drill box assembly; then the drill box assembly starts to rotate and feeds along the slide assembly until it contacts the drill rod, and through the rotation of the drill box assembly, the drill box assembly docks with the drill rod; then the fifth drive in the clamping part of the loading and unloading assembly extends, the first The jaws and second jaws release the drill rod, while the fourth actuator retracts, driving the clamping component back to its initial position. The drill box assembly then continues feeding the drill rod until drilling is complete. After drilling, the drill box assembly retracts along the slide assembly. When it reaches the docking position, the fourth actuator extends to push out the clamping component, and the fifth actuator retracts to grip the drill rod. The drill box assembly then continues to rotate and disassemble the drill rod. Next, the drill box assembly retracts to its initial position, while the fourth actuator retracts, and the clamping component moves the drill rod to the initial position of the integrated storage unit. Finally, the fifth actuator extends from the clamping component to release the drill rod.

[0056] (3) Injection action: The rod position chambers of the upper rod chamber assembly and the lower rod chamber assembly in the integrated bin device move synchronously, causing the dosing rod to be positioned at the clamping component of the loading and unloading assembly. The fifth drive in the clamping component retracts, causing the first and second grippers to grip the dosing rod; then the fourth drive pushes the linkage mechanism to move, which in turn causes the clamping component to move the dosing rod. When the fourth drive extends to its limit, the clamping component grabs the dosing rod to the designated position of the drill, that is, directly above the drill box assembly; then the drill box assembly starts to rotate and feeds along the slide assembly until it contacts the dosing rod, and through the rotation of the drill box assembly, the drill box assembly docks with the tail of the dosing rod; then the fifth drive in the clamping component of the loading and unloading assembly extends, the first and second grippers release the dosing rod, and at the same time the fourth drive retracts, causing the clamping component to return. The drill box assembly moves to the initial position; then, the drill box assembly drives the dosing rod to continue feeding until the tip of the dosing rod extends into the borehole; next, the drill box assembly uses water pressure to push the piston in the dosing rod, which in turn pushes the dosing cartridge into the borehole; then, the drill box assembly retracts along the slide assembly, and when it retracts to the docking position, the fourth actuator extends to push out the clamping component, and the fifth actuator retracts to grip the dosing rod; then, the drill box assembly continues to rotate to disassemble the dosing rod; then, the drill box assembly continues to retract to the initial position, while the fourth actuator retracts, and the clamping component moves the dosing rod to the initial position of the integrated chamber device; finally, the fifth actuator in the clamping component extends to release the dosing rod.

[0057] (4) Anchoring action: The rod position mechanism of the upper rod position assembly and the rod position mechanism of the lower rod position assembly in the integrated rod position assembly move synchronously, driving the anchor rod to be located at the clamping component. The fifth actuator in the clamping component retracts, causing the first and second jaws to grip the anchor rod. Then, the fourth actuator pushes the linkage mechanism, which in turn moves the anchor rod. When the fourth actuator extends to its limit, the clamping component picks up the anchor rod and positions it at the designated location on the drilling rig, directly above the drill box assembly. The drill box assembly then rotates and feeds along the slide assembly until it contacts the anchor rod. Through rotation, the drill box assembly aligns with the tail of the anchor rod. The fifth actuator in the clamping component then extends, releasing the anchor rod from the first and second jaws. Simultaneously, the fourth actuator retracts, returning the clamping component to its initial position. The drill box assembly then continues feeding the anchor rod, while the anchor rod carries the explosive cartridge into the bottom of the borehole. The drill box assembly continues to rotate, stirring the explosive cartridge before securing it. The drill box assembly then retracts along the slide assembly until it reaches its lowest point. Finally, the top plate assembly retracts to its original position, completing the operation.
