Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and specifically to an anchor bolt support system. Background Technology

[0002] In coal mine operations, bolt support is the primary method of roadway support, effectively ensuring production safety. Bolt support typically involves the sequential steps of drilling anchor holes, filling with anchoring agent, and installing anchor bolts.

[0003] In related technologies, during the process of assembling anchor bolts into the storage cylinder, if the rotating frame is not in a stable locked state, workers may accidentally rotate the storage cylinder due to accidental operation (such as accidentally touching the drive button or colliding with the equipment) or other unexpected factors, causing the anchor bolt to fall out of the storage cylinder. This will hinder the smooth implementation of the anchor bolt support construction steps, reduce production efficiency, and may even cause the anchor bolt to get stuck between the storage cylinder and surrounding equipment, damaging the equipment, or cause the anchor bolt to be thrown out and injure people, posing a risk of personal injury. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose an anchor bolt installation system that can lock the bolt storage compartment and has high safety performance.

[0006] An anchor bolt support system according to an embodiment of the present invention includes: a frame; an anchor bolt assembly, the anchor bolt assembly including a gooseneck support and a bolt storage bin, the gooseneck support being disposed on one side of the frame, the bolt storage bin being disposed within the gooseneck support and rotating within the gooseneck support, the bolt storage bin storing anchor bolts; and a rotating frame rotatably connected to the frame, the rotating frame having an anchor hole drilling assembly, an anchoring agent filling assembly, and an anchor bolt installation assembly, the anchor hole drilling assembly, the anchoring agent filling assembly, and the anchor bolt installation assembly being circumferentially spaced around the frame, the rotating frame being rotatable relative to the frame between a first position, a second position, and a third position around the frame's circumference, wherein in the first position, the anchor hole drilling assembly is adapted to be spaced vertically from a preset position. The anchor hole drilling assembly drills a hole at the preset position to form an anchor hole, and the anchor bolt installation assembly cooperates with the anchor bolt assembly to grip the anchor bolt. In the second position, the anchoring agent filling assembly is aligned vertically with the anchor hole to fill the anchoring agent. In the third position, the anchor bolt installation assembly is aligned vertically with the anchor hole to install the anchor bolt. A locking assembly is connected to the anchor bolt assembly and the rotating frame. The locking assembly has an unlocked state and a locked state. When the rotating frame is in either the second or the third position, the locking assembly is in the locked state, and the rod storage compartment is locked. When the rotating frame is in the first position, the locking assembly is in the unlocked state, and the rod storage compartment can rotate within the gooseneck support.

[0007] The anchor bolt support system of this invention includes a locking component. When the rotating frame is in the first or third position, the locking component locks the bolt storage chamber. This effectively avoids the risk of accidental rotation of the bolt storage chamber due to accidental contact by personnel, thus ensuring the safety of the anchor bolt installation process and the reliability of anchor bolt transportation and retrieval, effectively improving the quality of anchor bolt support and the stability of system operation.

[0008] In some embodiments, the anchor support system further includes a first telescopic cylinder and a second telescopic cylinder. The bases of the first telescopic cylinder and the second telescopic cylinder are connected. The piston rod of the first telescopic cylinder is connected to the gooseneck bracket, and the piston rod of the second telescopic cylinder is connected to the rotating frame. In the first position, both the first telescopic cylinder and the second telescopic cylinder are extended. In the second position, the first telescopic cylinder is extended and the second telescopic cylinder is shortened. In the third position, both the first telescopic cylinder and the second telescopic cylinder are shortened.

[0009] In some embodiments, the anchor bolt assembly further includes an oil supply assembly and a swing cylinder. The oil supply assembly supplies oil to the swing cylinder to drive the swing cylinder to rotate. The swing cylinder is connected to the rod storage chamber so that the swing cylinder drives the rod storage chamber to rotate. The locking assembly includes a sequence valve and a hydraulically controlled directional valve. One end of the sequence valve is connected to one of the rodless chambers of the first telescopic cylinder or the second telescopic cylinder. When the rotating frame is in the first position and the oil pressure in one of the rodless chambers of the first telescopic cylinder or the second telescopic cylinder is higher than a preset value, the sequence valve opens. The hydraulic oil in the rodless chamber of the first telescopic cylinder or the rodless chamber of the second telescopic cylinder drives the hydraulically controlled directional valve to switch direction, thereby opening the hydraulically controlled directional valve so that the oil supply assembly and the swing cylinder are connected.

[0010] In some embodiments, the anchor bolt assembly further includes an oil supply pipe and an oil outlet pipe. The oil supply assembly supplies oil to the swing cylinder through the oil supply pipe to drive the swing cylinder to rotate. The swing cylinder is connected to the oil supply assembly through the oil outlet pipe so that the hydraulic oil in the swing cylinder flows back to the oil supply assembly through the oil outlet pipe. The sequence valve includes a first sequence valve and a second sequence valve. The hydraulically controlled directional valve includes a first hydraulically controlled directional valve and a second hydraulically controlled directional valve. One end of the first sequence valve is connected to the rodless chamber of the first telescopic cylinder. The first hydraulically controlled directional valve is connected to the oil supply assembly and the swing cylinder through the oil supply pipe. The first sequence valve cooperates with the first hydraulically controlled directional valve so that when the rotating frame is in the first position and the oil pressure in the rodless chamber of the first telescopic cylinder is higher than a preset value, the first sequence valve opens. The hydraulic oil in the first telescopic cylinder drives the first hydraulic directional valve to switch direction through the first sequence valve, thereby opening the first hydraulic directional valve. This allows the oil supply assembly to communicate with the swing cylinder through the first hydraulic directional valve. One end of the second sequence valve is connected to the rodless chamber of the second telescopic cylinder. The second hydraulic directional valve is connected to the oil supply assembly and the swing cylinder through the oil outlet pipe. The second sequence valve cooperates with the second hydraulic directional valve so that when the rotating frame is in the first position and the oil pressure in the rodless chamber of the second telescopic cylinder is higher than a preset value, the second sequence valve opens. This allows the hydraulic oil in the second telescopic cylinder to drive the second hydraulic directional valve to switch direction through the second sequence valve, thereby opening the second hydraulic directional valve. This allows the oil supply assembly to communicate with the swing cylinder through the second hydraulic directional valve.

[0011] In some embodiments, the anchor bolt support system further includes a first check valve and a second check valve. The two ends of the first check valve are respectively connected to the rodless chamber of the first telescopic cylinder and the first hydraulic directional valve, so that when the first hydraulic directional valve switches, the hydraulic oil in the first hydraulic directional valve flows unidirectionally into the rodless chamber of the first telescopic cylinder. The two ends of the second check valve are respectively connected to the rodless chamber of the second telescopic cylinder and the second hydraulic directional valve, so that when the second hydraulic directional valve switches, the hydraulic oil in the second hydraulic directional valve flows unidirectionally into the rodless chamber of the second telescopic cylinder.

[0012] In some embodiments, the anchor support system further includes a first pressure sensor and a second pressure sensor. The first pressure sensor is disposed between the first sequence valve and the first hydraulic directional valve so that the first pressure sensor detects the pressure between the first sequence valve and the first hydraulic directional valve. The second pressure sensor is disposed between the second sequence valve and the second hydraulic directional valve so that the second pressure sensor detects the pressure between the second sequence valve and the second hydraulic directional valve.

Detailed Implementation

[0022] 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.

[0023] An anchor bolt support system 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0024] like Figures 1-8 As shown, the anchor bolt support system 100 according to an embodiment of the present invention includes a frame 1, an anchor bolt assembly 3, a rotating frame 4, and a locking assembly 2.

[0025] The anchor bolt assembly 3 includes a gooseneck support 31 and a bolt storage bin 32. The gooseneck support 31 is located on one side of the frame 1, and the bolt storage bin 32 is located inside the gooseneck support 31 and rotates within the gooseneck support 31. The bolt storage bin 32 stores anchor bolts 431. Specifically, as... Figures 1-6 As shown, the frame 1 serves as the supporting frame and basic positioning structure for the entire equipment. The gooseneck support 31 is connected to the frame 1. The gooseneck support 31 is wrapped in a ring around the outside of the rod storage bin 32. The rod storage bin 32 is located inside the gooseneck support 31 and can rotate within the gooseneck support 31. The rod storage bin 32 stores multiple anchor rods 431.

[0026] The rotating frame 4 is rotatably connected to the frame 1. The rotating frame 4 is equipped with an anchor hole drilling assembly 41, an anchoring agent filling assembly 42, and an anchor bolt installation assembly 43. The anchor hole drilling assembly 41, the anchoring agent filling assembly 42, and the anchor bolt installation assembly 43 are arranged circumferentially around the frame 1. The rotating frame 4 is rotatable relative to the frame 1 between a first position, a second position, and a third position. In the first position, the anchor hole drilling assembly 41 is adapted to be arranged vertically and vertically relative to a preset position so that the anchor hole drilling assembly 41 drills a hole at the preset position to form an anchor hole, and the anchor bolt installation assembly 43 cooperates with the anchor bolt assembly 3 to grasp the anchor bolt 431. In the second position, the anchoring agent filling assembly is vertically opposite to the anchor hole to fill the anchoring agent. In the third position, the anchor bolt installation assembly 43 is vertically opposite to the anchor hole to install the anchor bolt 431.

[0027] Specifically, such as Figures 1-6 As shown, the frame 1 includes a positioning shaft, a first telescopic rod, and a positioning tip, all coaxially arranged. The positioning shaft and the positioning tip are located at opposite ends of the first telescopic rod, forming a stable axial positioning system. The first telescopic rod is length-adjustable, allowing for flexible adjustment of the distance between the positioning shaft and the positioning tip based on the plane height of the area to be anchored. The first telescopic rod extends vertically along the frame. Since the distance between the top of the rotating frame and the positioning tip is relatively small, adjusting the distance between the positioning shaft and the positioning tip via the first telescopic rod correspondingly adjusts the distance from the top of the rotating frame to the positioning tip, preventing the positioning tip from failing to reach the area to be anchored due to excessively small distances, thus adapting to different working conditions.

[0028] The second telescopic rod can drive the rotating frame and its onboard anchor hole drilling assembly, anchor filling assembly, and anchor bolt installation assembly to move along the axial direction of the positioning axis. This allows each component on the rotating frame to adjust its distance from the working surface according to operational needs, thus better adapting to drilling and anchoring operations at different depths and positions. The rotating frame 4 has the ability to rotate around the axial direction of the frame 1. The anchor hole drilling assembly 41, anchor filling assembly 42, and anchor bolt installation assembly 43 are evenly arranged on the rotating frame 4 at certain intervals along its circumference. During operation, the rotating frame 4 can drive the above three components to move sequentially to preset positions (such as the anchoring points in the area to be anchored), thereby enabling the rotating frame 4 to quickly switch between the first, second, and third positions, improving the equipment's operational efficiency and flexibility.

[0029] When anchor hole drilling is carried out, the rotating frame 4 is in the first position, at which point the anchor hole drilling assembly 41 is accurately positioned to complete the drilling operation. Simultaneously, the anchor bolt installation assembly 43 works in conjunction with the anchor bolt assembly 3, gripping the anchor bolt 431 to prepare for the subsequent anchor bolt 431 installation. After drilling is completed, the rotating frame 4 is switched to the second position, where the anchoring agent filling assembly 42 performs the anchoring agent filling operation. Finally, the rotating frame 4 is switched to the third working position, positioning the anchor bolt installation assembly 43 in the appropriate working position to complete the anchor bolt 431 installation. The entire operation process is smooth, efficient, and orderly, eliminating the need for frequent manual movement of equipment or adjustment of component positions, effectively saving operation time and reducing labor costs.

[0030] Locking component 2 is connected to anchor bolt assembly 3 and rotating frame 4. Locking component 2 has an unlocked state and a locked state. In the locked state, rotating frame 4 is in either a second or third position, and the rod storage compartment 32 is locked. In the unlocked state, rotating frame 4 is in a first position, and rod storage compartment 32 can rotate within gooseneck support 31. Specifically, as... Figure 7 and Figure 8 As shown, the locking component 2 cooperates with the anchor bolt assembly 3 and the rotating frame 4 and has unlocked and locked states. When the rotating frame 4 is in the second or third position, the locking component 2 enters the locked state. In this state, the rotation function of the rod storage chamber 32 is restricted and its position is locked. Even if the operator drives the rod storage chamber 32 to rotate, the rod storage chamber 32 will remain stationary and will not rotate, avoiding any impact on operational accuracy and safety due to accidental rotation of the rod storage chamber 32.

[0031] When the rotating frame 4 rotates to the first position, the locking component 2 switches to the unlocked state. At this time, the operator gains driving authority over the rod storage compartment 32 and can flexibly drive the rod storage compartment 32 to rotate according to actual operational needs, so that the anchor bolt installation component 43 can grab the anchor bolt 431.

[0032] The anchor bolt support system 100 of this embodiment of the invention is equipped with a locking component 2. When the rotating frame 4 is in the second or third position, the locking component 2 locks the bolt storage chamber 32. In this state, the bolt storage chamber 32 is locked, which effectively avoids the risk of accidental rotation of the bolt storage chamber 32 due to accidental contact by personnel, thereby preventing personnel injury accidents caused during the installation of anchor bolts 431. When the rotating frame 4 switches to the first position, the locking component 2 releases the locking constraint on the bolt storage chamber 32, and the personnel can drive the bolt storage chamber 32 to rotate. At this time, the anchor bolt installation component 43 can grab the anchor bolts 431 in the bolt storage chamber 32. Thus, through the locking-unlocking linkage mechanism of the locking component 2, the safety of the anchor bolt 431 installation process is ensured, as well as the reliability of the anchor bolt 431 transfer and grabbing, effectively improving the quality of anchor bolt 431 support and the stability of system operation.

[0033] In some embodiments, the anchor bolt support system 100 further includes a first telescopic cylinder 5 and a second telescopic cylinder 6. The base of the first telescopic cylinder 5 and the base of the second telescopic cylinder 6 are connected. The piston rod of the first telescopic cylinder 5 is connected to the gooseneck bracket 31, and the piston rod of the second telescopic cylinder 6 is connected to the rotating frame 4. In a first position, both the first telescopic cylinder 5 and the second telescopic cylinder 6 are extended. In a second position, both the first telescopic cylinder 5 and the second telescopic cylinder 6 are extended. In a third position, both the first telescopic cylinder 5 and the second telescopic cylinder 6 are shortened. Specifically, as shown... Figure 3 As shown, both the first telescopic cylinder 5 and the second telescopic cylinder 6 can extend horizontally. The bases of the first telescopic cylinder 5 and the second telescopic cylinder 6 are connected. The piston rod of the first telescopic cylinder 5 is hinged to the rotating frame 4, and the piston rod of the second telescopic cylinder 6 is hinged to the gooseneck bracket 31. Thus, the telescopic movement of the first telescopic cylinder 5 and the second telescopic cylinder 6 drives the rotating frame 4 to rotate between the first position, the second position, and the third position. When the rotating frame 4 is in the first position, both the first telescopic cylinder 5 and the second telescopic cylinder 6 are in the extended state. At this time, the piston rods of the first telescopic cylinder 5 and the second telescopic cylinder 6 extend, causing the anchor hole drilling assembly 41 to be appropriately positioned vertically at a predetermined location, preparing for subsequent anchor hole drilling operations. At the same time, the anchor bolt installation assembly 43 can also effectively cooperate with the anchor bolt assembly 3 to grip the anchor bolt 431.

[0034] When the rotating frame 4 needs to be rotated to the second position, the first telescopic cylinder 5 extends and the piston rod of the first telescopic cylinder 5 extends outward. At the same time, the second telescopic cylinder 6 remains in the shortened state, so that the rotating frame 4 rotates to the second position. In this position, the anchor hole drilling assembly 41 is accurately aligned with the anchor hole in the vertical direction, which facilitates the filling operation of the anchoring agent.

[0035] When the rotating frame 4 rotates to the third position, both the first telescopic cylinder 5 and the second telescopic cylinder 6 shorten. The piston rods of both cylinders retract inward simultaneously, providing sufficient power to the rotating frame 4 so that it can smoothly rotate to the third position. In the third position, the anchor bolt mounting assembly 43 is precisely aligned with the anchor hole in the vertical direction, thereby achieving accurate installation of the anchor bolt 431.

[0036] In some embodiments, the anchor bolt assembly 3 further includes an oil supply assembly 21 and a swing cylinder 22. The oil supply assembly 21 supplies oil to the swing cylinder 22 to drive the swing cylinder 22 to rotate. The swing cylinder 22 is connected to the rod storage chamber 32 so that the swing cylinder 22 drives the rod storage chamber 32 to rotate. Specifically, as Figure 7 and Figure 8 As shown, the oil supply component 21 can be installed on the frame 1 and connected to the swing cylinder 22, so that the oil supply component 21 supplies oil to the swing cylinder 22. The output shaft of the swing cylinder 22 is connected to the rod storage chamber 32. When the swing cylinder 22 rotates under the drive of hydraulic oil, its output shaft drives the rod storage chamber 32 to rotate synchronously, so that the rod storage chamber 32 can adjust the removal position of the anchor bolt 431 according to the actual operation requirements, which provides convenience for the anchor bolt installation component 43 to grab the anchor bolt 431, thereby improving the working efficiency and operational flexibility of the entire anchor bolt support system 100.

[0037] In some embodiments, the locking assembly 2 includes a sequence valve 23 and a hydraulically controlled directional valve 24. One end of the sequence valve 23 is connected to either the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6. When the rotating frame 4 is in a first position and the oil pressure in either the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6 is higher than a preset value, the sequence valve 23 opens, and the hydraulic oil in the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6 drives the hydraulically controlled directional valve 24 to switch, thereby opening the hydraulically controlled directional valve 24 to connect the oil supply assembly 21 and the swing cylinder 22. Specifically, as shown... Figure 7 and Figure 8As shown, the inlet of the sequence valve 23 is connected to either the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6. The sequence valve 23 is connected to the hydraulic directional valve 24, which moves horizontally between the disconnected and connected positions. The inlet of the hydraulic directional valve 24 is connected to the oil supply assembly 21, and the outlet of the hydraulic directional valve 24 is connected to the swing cylinder 22. When the oil pressure in the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6 is lower than a preset value, the sequence valve 23 closes, and the hydraulic directional valve 24 is in the disconnected position under the elastic force of its own spring. This disconnects the oil supply assembly 21 from the swing cylinder 22 through the hydraulic directional valve 24. When the oil pressure in the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6 is higher than a preset value (i.e., when both the first telescopic cylinder 5 and the second telescopic cylinder 6 are fully extended to place the rotating frame 4 in the first position), the sequence valve 23 closes, and the hydraulic directional valve 24 is in the disconnected position under the elastic force of its own spring. (When the oil pressure in the rodless chamber of the first telescopic cylinder 5 and the oil pressure in the rodless chamber of the second telescopic cylinder 6 are both greater than the preset value), the sequence valve 23 is opened, and the hydraulic oil in the rodless chamber of the first telescopic cylinder 5 or the rodless chamber of the second telescopic cylinder 6 flows into the hydraulic control directional valve 24 through the sequence valve 23, so that the valve core of the hydraulic control directional valve 24 overcomes the restoring force of its own spring and moves in the horizontal direction, switching from the disconnected position to the connected position, thereby enabling the oil supply component 21 to supply oil to the hydraulic swing cylinder 22 through the hydraulic control directional valve 24.

[0038] In some embodiments, the anchor bolt assembly 3 further includes an oil supply pipe 25 and an oil outlet pipe 26. The oil supply assembly 21 supplies oil to the swing cylinder 22 through the oil supply pipe 25 to drive the swing cylinder 22 to rotate. The swing cylinder 22 is connected to the oil supply assembly 21 through the oil outlet pipe 26 so that the hydraulic oil in the swing cylinder 22 flows back to the oil supply assembly 21 through the oil outlet pipe 26. Specifically, as shown... Figure 7 and Figure 8 As shown, the inlet of the oil supply pipe 25 is connected to the outlet of the oil supply assembly 21, and the outlet of the oil supply pipe 25 is connected to the inlet of the swing cylinder 22, allowing the oil supply assembly 21 to supply oil to the swing cylinder 22 through the oil supply pipe 25. The inlet of the oil outlet pipe 26 is connected to the outlet of the swing cylinder 22, and the inlet of the oil outlet pipe 26 is connected to the inlet of the oil supply assembly 21. The hydraulic oil in the swing cylinder 22 flows back to the oil supply assembly 21 through the oil outlet pipe 26. When the position of the rod storage chamber 32 needs to be adjusted, the oil supply assembly 21 starts working, supplying high-pressure hydraulic oil to the swing cylinder 22 through the oil supply pipe 25. The swing cylinder 22 rotates under the action of the hydraulic oil, causing the rod storage chamber 32 to rotate accordingly. When the rod storage chamber 32 reaches the designated position, the oil supply assembly 21 stops supplying oil, and the hydraulic oil in the swing cylinder 22 slowly flows back to the oil supply assembly 21 through the oil outlet pipe 26, completing one complete hydraulic drive and cycle process.

[0039] In some embodiments, the sequence valve 23 includes a first sequence valve 231 and a second sequence valve 232, and the hydraulic directional valve 24 includes a first hydraulic directional valve 241 and a second hydraulic directional valve 242. One end of the first sequence valve 231 is connected to the rodless chamber of the first telescopic cylinder 5. The first hydraulic directional valve 241 is connected to the oil supply assembly 21 and the swing cylinder 22 through the oil supply pipe 25. The first sequence valve 231 cooperates with the first hydraulic directional valve 241 so that when the rotating frame 4 is in the first position and the oil pressure in the rodless chamber of the first telescopic cylinder 5 is higher than a preset value, the first sequence valve 231 opens, so that the hydraulic oil in the first telescopic cylinder 5 drives the first hydraulic directional valve 241 to switch direction through the first sequence valve 231, so that the first hydraulic directional valve 241 opens, so that the oil supply assembly 21 is connected to the swing cylinder 22 through the first hydraulic directional valve 241. Specifically, as shown in the figure... Figure 7 and Figure 8 As shown, the inlet of the first sequence valve 231 is connected to the rodless chamber of the first telescopic cylinder 5, and the outlet of the first sequence valve 231 is connected to the first hydraulic directional valve 241. The first hydraulic directional valve 241 is connected to the oil supply assembly 21 and the swing cylinder 22 through the oil supply pipe 25. When the oil pressure in the rodless chamber of the first telescopic cylinder 5 is lower than a preset value, the first sequence valve 231 closes and the first hydraulic directional valve 241 is in the open position under the elastic force of its own spring, thereby allowing the oil supply assembly 21 to communicate with the first hydraulic directional valve 241. When the swing cylinder 22 is disconnected, and the rotating frame 4 is in the first position and the oil pressure in the rodless chamber of the first telescopic cylinder 5 is higher than the preset value, the first sequence valve 231 is opened. The hydraulic oil in the rodless chamber of the first telescopic cylinder 5 flows into the first hydraulic control directional valve 241 through the first sequence valve 231, so that the valve core of the first hydraulic control directional valve 241 overcomes the restoring force of its own spring and moves in the horizontal direction, switching from the disconnected position to the connected position, thereby enabling the oil supply component 21 to supply oil to the swing cylinder 22 through the driving hydraulic system of the first hydraulic control directional valve 241.

[0040] One end of the second sequence valve 232 is connected to the rodless chamber of the second telescopic cylinder 6. The second hydraulically controlled directional valve 242 is connected to the oil supply assembly 21 and the swing cylinder 22 through the oil outlet pipe 26. The second sequence valve 232 cooperates with the second hydraulically controlled directional valve 242 so that when the rotating frame 4 is in the first position and the oil pressure in the rodless chamber of the second telescopic cylinder 6 is higher than a preset value, the second sequence valve 232 opens, so that the hydraulic oil in the second telescopic cylinder 6 drives the second hydraulically controlled directional valve 242 to switch direction, so that the second hydraulically controlled directional valve 242 opens, so that the oil supply assembly 21 is connected to the swing cylinder 22 through the second hydraulically controlled directional valve 242. Specifically, as shown in the figure... Figure 7 and Figure 8As shown, the inlet of the second sequence valve 232 is connected to the rodless chamber of the second telescopic cylinder 6, and the outlet of the second sequence valve 232 is connected to the second hydraulic directional valve 242. The second hydraulic directional valve 242 is connected to the oil supply assembly 21 and the swing cylinder 22 through the oil outlet pipe 26. When the oil pressure in the rodless chamber of the second telescopic cylinder 6 is lower than the preset value, the second sequence valve 232 closes and the second hydraulic directional valve 242 is in the open position under the elastic force of its own spring, thereby allowing the oil supply assembly 21 to connect with the swing cylinder 22 through the second hydraulic directional valve 242. When the rotating frame 4 is in the first position and the oil pressure in the rodless chamber of the second telescopic cylinder 6 is higher than the preset value, the second sequence valve 232 opens. The hydraulic oil in the rodless chamber of the second telescopic cylinder 6 flows into the first hydraulic control directional valve 241 through the second sequence valve 232, causing the valve core of the second hydraulic control directional valve 242 to overcome the restoring force of its own spring and move in the horizontal direction, switching from the disconnected position to the connected position, thereby allowing the hydraulic oil in the swing cylinder 22 to flow back to the oil supply assembly 21 through the second hydraulic control directional valve 242.

[0041] It is worth noting that the drill frame is a fully automatic drill frame, and every action it performs is instructed by the controller. Whether the execution is completed requires sensor measurement, and the measured value is transmitted to the controller for judgment. After the first telescopic cylinder 5 and the second telescopic cylinder 6 are fully extended (physical action), the oil supply system pressure will increase (in order to prevent the system pressure from rising indefinitely, it will be limited to a relatively high pressure, such as 12 MPa, which is greater than the set opening pressure of the locking component sequence valve of 10 MPa). After the system pressure reaches the controller's judgment value, the controller determines that the first telescopic cylinder 5 and the second telescopic cylinder 6 are indeed fully extended (as defined by the controller).

[0042] In other words, there is a time difference between the full extension of the first telescopic cylinder 5 and the second telescopic cylinder 6 as defined by the controller, which will inevitably increase the pressure of the oil supply system. By manually setting the judgment value and the pressure difference of the sequence valve opening, the locking component can be reliably operated in the locked and unlocked positions.

[0043] In some embodiments, the anchor bolt assembly 3 further includes a first check valve 27 and a second check valve 28. The two ends of the first check valve 27 are respectively connected to the rodless chamber of the first telescopic cylinder 5 and the first hydraulically controlled directional valve 241, so that when the first hydraulically controlled directional valve 241 is switched, the hydraulic oil in the first hydraulically controlled directional valve 241 flows unidirectionally into the rodless chamber of the first telescopic cylinder 5. Specifically, as... Figure 7 and Figure 8As shown, the inlet of the first check valve 27 is connected to the first hydraulic directional valve 241, and the outlet of the first check valve 27 is connected to the rodless chamber of the first telescopic cylinder 5. Thus, when the first hydraulic directional valve 241 switches from the connected position to the disconnected position, the hydraulic oil of the first hydraulic directional valve 241 flows back to the first telescopic cylinder 5 through the first check valve 27. The first check valve 27 prevents the hydraulic oil in the rodless chamber of the first telescopic cylinder 5 from flowing to the first hydraulic directional valve 241, thereby ensuring the reliable switching of the first hydraulic check valve 241.

[0044] The two ends of the second one-way valve 28 are respectively connected to the rodless chamber of the second telescopic cylinder 6 and the second hydraulically controlled directional valve 242, so that when the second hydraulically controlled directional valve 242 switches, the hydraulic oil in the second hydraulically controlled directional valve 242 flows unidirectionally into the rodless chamber of the second telescopic cylinder 6. Specifically, as shown... Figure 7 and Figure 8 As shown, the inlet of the second check valve 28 is connected to the second hydraulically controlled directional valve 242, and the outlet of the second check valve 28 is connected to the rodless chamber of the second telescopic cylinder 6. Therefore, when the second hydraulically controlled directional valve 242 switches from the connected position to the disconnected position, the hydraulic oil in the second hydraulically controlled directional valve 242 flows back into the second telescopic cylinder 6 through the second check valve 28. The first check valve 27 prevents the hydraulic oil in the rodless chamber of the second telescopic cylinder 6 from flowing into the second hydraulically controlled directional valve 242, thus ensuring the efficiency of the switching of the second hydraulically controlled directional valve 242. This ensures the reliable switching of the second hydraulically controlled directional valve 242.

[0045] In some embodiments, the anchor bolt support system 100 further includes a first pressure sensor 29 and a second pressure sensor 201. The first pressure sensor 29 is disposed between a first sequence valve 231 and a first hydraulic directional valve 241 to detect the pressure between the first sequence valve 231 and the first hydraulic directional valve 241. The second pressure sensor 201 is disposed between a second sequence valve 232 and a second hydraulic directional valve 242 to detect the pressure between the second sequence valve 232 and the second hydraulic directional valve 242. Specifically, as shown... Figure 7 and Figure 8 As shown, the first pressure sensor 29 is used to detect the pressure between the first sequence valve 231 and the first hydraulic directional valve 241. When the first pressure sensor 29 detects an abnormal increase in pressure, the valve core of the first hydraulic directional valve 241 may become stuck. When the first pressure sensor 29 detects an abnormal decrease in pressure, the first sequence valve 231 may not be properly sealed or there may be damage to the pipeline. This allows maintenance personnel to make corresponding adjustments and troubleshooting based on the first pressure sensor 29, thereby ensuring that the first sequence valve 231 and the first hydraulic directional valve 241 can work normally and stably, and ensuring the accurate execution of actions related to the first telescopic cylinder 5 in the anchor bolt support system 100.

[0046] The second pressure sensor 201 is used to detect the pressure between the second sequence valve 232 and the second hydraulic directional valve 242. When the second pressure sensor 201 detects an abnormal increase in pressure, the valve core of the second hydraulic directional valve 242 may become stuck. When the second pressure sensor 201 detects an abnormal decrease in pressure, the second sequence valve 232 may not be properly sealed or there may be damage to the pipeline. This allows maintenance personnel to make corresponding adjustments and troubleshooting based on the second pressure sensor 201, thereby ensuring that the second sequence valve 232 and the second hydraulic directional valve 242 can work normally and stably, and ensuring the accurate execution of actions related to the second telescopic cylinder 6 in the anchor bolt support system 100.

[0047] In some embodiments, the rod storage compartment 32 includes a rotating shaft 321, a base 322, and a rod storage disk 323. The rotating shaft 321 is rotatably connected to the gooseneck support 31. The base 322 and the rod storage disk 323 are sleeved on the rotating shaft 321. The base 322 is used to support the anchor rod 431. The rod storage disk 323 is provided with a plurality of grooves 324 spaced apart for accommodating the anchor rod 431. Specifically, as shown... Figures 1-6 As shown, the gooseneck support 31 is connected to the frame 1, and the gooseneck support 31 is wrapped in a ring around the outside of the rod storage chamber 32. The rotating shaft 321 is rotatably connected to the gooseneck support 31 and is also connected to the swing cylinder 22, so that the swing cylinder 22 drives the base 322, the rod storage plate 323, and the placed anchor rods 431 to rotate through the rotating shaft 321. The base 322 is located at the bottom of the rod storage chamber 32 to support the anchor rods 431, and the base 322 has an opening. The outer circumferential surface of the rod storage plate 323 has a plurality of grooves 324 spaced along its circumference. The shape and size of these grooves 324 are matched with the outer dimensions of the anchor rods 431. The grooves 324 can accommodate the anchor rods 431 and prevent the anchor rods 431 from shaking or colliding during rotation.

[0048] Optionally, multiple rod storage disks 323 are provided, and the multiple rod storage disks 323 are spaced apart along the axial direction of the rotation shaft 321 to securely position the anchor rod 431.

[0049] In some embodiments, the anchor bolt installation assembly 43 includes an anchor bolt drill box 432 and an anchor bolt clamp 433. The anchor bolt drill box 432 is movable vertically relative to the rotating frame 4. The anchor bolt clamp 433 includes a base 4331, a jaw 4332, and an elastic element 4333. The base 4331 is disposed on the rotating frame 4, and the jaw 4332 is rotatable relative to the base 4331. The two ends of the elastic element 4333 are correspondingly connected to the base 4331 and the jaw 4332. The jaw 4332 is used to clamp the anchor bolt 431 on the anchor bolt drill box 432. Specifically, as shown... Figure 4As shown, the anchor bolt drill box 432 and the anchor bolt clamp 433 are both mounted on the rotating frame 4. The anchor bolt drill box 432 can be used to install the anchor bolt 431 and can move up and down on the rotating frame 4 to drive the anchor bolt 431 into the preset position to complete the anchoring operation.

[0050] The anchor bolt clamp 433 is used to remove the anchor bolt 431 from the bolt storage chamber 32 and install it onto the output end of the anchor bolt drill box 432. The anchor bolt clamp 433 is located in the forward direction of the anchor bolt drill box 432. As the anchor bolt drill box 432 moves vertically on the rotating frame 4, it pushes against the gripper 4332, allowing the gripper 4332 to rotate relative to the base 4331 and causing the elastic element 4333 to undergo elastic deformation. At this time, the anchor bolt clamp 433 disengages from the anchor bolt 431, facilitating the movement of the anchor bolt drill box 432 and the installation of the anchor bolt 431. When the anchor bolt drill box 432 retracts past the position of the anchor bolt clamp 433, the gripper 4332 can return to its initial position under the deformation of the elastic element 4333 or external force, facilitating the installation of the anchor bolt 431 in the next process.

[0051] During operation, when the rotating frame 4 is in the second or third position, both the first hydraulic directional valve 241 and the second hydraulic directional valve 242 are in the off state. At this time, the oil supply assembly 31 cannot supply oil to the swing cylinder 22 through the oil supply pipe 25. In this way, even if the operator accidentally activates the oil supply assembly 31, the swing cylinder 22 will remain stationary, preventing the rod storage chamber 32 from rotating unexpectedly.

[0052] When the rotating frame 4 is in the first position, both the first hydraulic control directional valve 241 and the second hydraulic control directional valve 242 are switched to the connected state. At this time, the anchor bolt drill box 432 and the anchor bolt clamp 433 will rotate together with the rotating frame 4 to one side of the anchor bolt assembly 3, with the anchor bolt clamp 433 located above the opening of the chassis 322 and the anchor bolt drill box 432 located below the opening of the chassis 322. Subsequently, the oil supply assembly 31 begins to supply oil to the swing cylinder 22, driving the rod storage plate 323 on the rod storage chamber 32, the chassis 322, and the anchor bolts 431 on it to rotate. As the rod storage chamber 32 rotates, the anchor bolts 431 in the rod storage chamber 32 will move sequentially into the clamp 4332 and be clamped and fixed by the clamp 4332.

[0053] When the anchor bolt installation assembly 43 needs to work, the first telescopic cylinder 5 and the second telescopic cylinder 6 will drive the anchor bolt installation assembly 43 to rotate through the rotating frame 4. At this time, the anchor bolt 431 will move out of the storage chamber 32 and fall into the output end of the anchor bolt drill box 432 under the action of gravity, thus realizing the installation of the anchor bolt 431 and the anchor bolt drill box 432.

[0054] It is worth noting that the present invention does not restrict the vertical movement of the anchor bolt drill box 432. For example, a linear slide rail is set on the rotating frame 4, and the anchor bolt drill box 432 moves vertically on the linear slide rail. In addition, the anchor bolt clamp 433 can also be an electric anchor bolt clamp 433, which is driven by a motor to open or close the jaws 4332 to clamp the anchor bolt 431, thereby improving the clamping stability of the anchor bolt clamp 433.

[0055] In some embodiments, multiple anchor bolt clamps 433 are provided, and the multiple anchor bolt clamps 433 are arranged vertically at intervals on the rotating frame 4. Specifically, as shown in the figure Figure 4 As shown, multiple anchor bolt clamps 433 can be set, and the multiple anchor bolt clamps 433 are spaced apart in the vertical direction, thereby improving the clamping stability of the anchor bolt clamps 433.

[0056] In some embodiments, the anchor clamp 433 located on the side of the rotating frame 4 near the anchor drill box 432 is a first clamp 433a, and the anchor clamp 433 located on the side of the rotating frame 4 near the top of the rotating frame 4 is a second clamp 433b. The rotation angle of the jaws 4332 in the first clamp 433a in the front-back direction is set to 0° to 110°, and the rotation angle of the jaws 4332 in the second clamp 433b in the front-back direction is set to 0° to 60°. Specifically, as shown... Figure 4 As shown, in the vertical direction of the rotating frame 4, the second clamp 433b is located above the first clamp 433a. When the rotating frame 4 drives the anchor bolt drill box 432 to the third position, the anchor bolt drill box 432 drives the anchor bolt 431 to rotate, and the anchor bolt 431 moves vertically relative to the rotating frame 4, so that the anchor bolt 431 is driven into the preset position. During the vertical movement of the anchor bolt drill box 432, the anchor bolt drill box 432 will first push against the jaw 4332 in the first clamp 433a to rotate until the anchor bolt drill box 432 passes through the area where the first clamp 433a is located. At this time, the rotation angle of the jaw 4332 in the first clamp 433a is greater than or equal to 90°, which facilitates the return of the anchor bolt drill box 432. If the anchor bolt drill box 432 does not completely pass through the area where the second clamp 433b is located, the jaw 4332 in the second clamp 433b will return to its original position under the action of the elastic element 4333 after the anchor bolt drill box 432 returns, preparing for the next installation of the anchor bolt 431, thus making the anchor bolt installation assembly 43 more reasonably set.
