Description

Continuous Operation Anchor Bolt and Cable Recovery Device for Fully Mechanized Mining Faces Technical Field

[0001] This utility model belongs to the technical field of coal mine equipment and relates to a device for recovering anchor bolts and cables for continuous operation in fully mechanized mining faces. Background Technology

[0002] In recent years, as the mining of coal resources in my country has extended to deeper areas, geological disasters such as high ground stress have become increasingly apparent. Coal wall spalling and deformation of the surrounding rock surface have made roadway maintenance difficult. Some mines have adopted a combination of high-strength anchor cables, anchor bolts, and metal mesh for support to avoid the impact of dynamic pressure. After support, the amount of roadway deformation has been significantly reduced, and the support effect is obvious. However, anchor bolts and anchor cables can enter the coal flow transportation system during subsequent mining, causing the scraper conveyor to jam, resulting in scraper breakage, chain breakage, and belt surface tearing accidents.

[0003] Patent CN220101304U discloses a coal mine underground anchor puller, a portable anchor bolt remover. It uses a motor-driven transmission disc-rotor-transmission frame-mounting plate reciprocating motion, causing an elastic locking component to bounce and advance on the anchor bolt's transverse rib using an inclined surface, causing the anchor bolt to slide backward. Simultaneously, the anchor bolt end is locked by a fixing locking component in the mounting box to prevent retraction. While this device can pull out the anchor bolt according to its principle, its pull-out force design limit is low for anchor bolts with high anchoring forces, making it difficult to overcome high anchoring force conditions. For high-position anchor bolts, operation requires climbing, increasing the risk of fall. When working near the mining face, dynamic load disturbance of the surrounding rock can easily cause the device to become unstable. Patent CN214091921U discloses another coal mine underground anchor puller, which adopts a mechanical-hydraulic composite structure, specifically composed of a double-stage hinge mechanism, and is integrated and installed on an advanced support hydraulic support. Its working principle is as follows: by driving two hydraulic cylinders to perform alternating telescopic movements, the force acting on the articulated mechanism is transmitted to the anchor bolt cable body in the coal face, realizing the pull-out and recovery of the anchor bolt cable. Although the device can remove the anchor bolt, its stroke is limited by the telescopic rod itself. For long anchor bolts, multiple fixations are required for pull-out. At the same time, due to the large structural size of the device, the overall space occupied is significantly increased. Both of the above technical solutions forcibly apply mechanical force to remove the anchor bolt and anchor cable while the support structure is intact. They still have defects in actual field applications. Therefore, it is urgent to develop a new anchor bolt and anchor cable recovery device for continuous operation in fully mechanized mining faces to prevent the anchor bolt and anchor cable from entering the coal flow transportation system and damaging production equipment, thereby improving production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous operation anchor bolt and cable recovery device for fully mechanized mining faces, which can recover anchor bolts and cables without stopping the machine during the underground mining process, thus preventing the anchor bolts and cables from entering the coal flow transportation system.

[0005] The technical solution adopted in this utility model is a continuous operation anchor bolt and anchor cable recovery device for fully mechanized mining faces, including a motor, a brake installed on one side of the motor, and a drum connected to the other side of the motor. The brake is connected to a first control valve through a pipeline, and the motor is connected to a second control valve through a pipeline. A rope presser is fixed on the drum, and a traction rope is wound on the drum. One end of the traction rope is fixed to the rope presser, and the other end of the traction rope is connected to a horseshoe ring. The horseshoe ring is connected to a free rope, and the free rope is connected to an anchor cable or anchor bolt.

[0006] The features of this utility model's continuous operation anchor bolt and cable recovery device for fully mechanized mining faces also include:

[0007] The drum includes a sleeve, a flange is fixed to the outside of the sleeve, a rope presser is fixed to the side of the flange away from the motor, and a drum shaft is fixed axially inside the sleeve, with a groove on the drum shaft; a motor shaft is provided on the motor, and a locking block is fixed on the motor shaft, the shape and size of the locking block are adapted to the locking groove, and the locking block is fixed in the locking groove.

[0008] The motor and drum are fixed together on the frame, and a protective plate is installed on the top of the frame.

[0009] The motor has a motor return port, a motor forward rotation inlet port, and a motor reverse rotation inlet port. The motor return port, the motor forward rotation inlet port, and the motor reverse rotation inlet port are each connected to a second control valve through pipelines. The brake has a brake inlet port, which is connected to a first control valve through pipelines.

[0010] One end of the traction rope is folded back and fixed with a buckle to form a first pear-shaped loop, which is connected to a horseshoe loop. The two ends of the free rope are folded back and fixed with a buckle to form a second and a third pear-shaped loop, respectively. The second pear-shaped loop is connected to the horseshoe loop, and the third pear-shaped loop is connected to the anchor cable or anchor rod.

[0011] The third pear-shaped ring is connected to a lifting eye nut, which is connected to the anchor rod. The fastening nut is tightened onto the exposed end of the anchor rod, and a tray is fitted onto the anchor rod.

[0012] The third pear-shaped ring is connected to a chain link, which is sleeved on the anchor cable. An anchor cable lock is fixed to the end of the anchor cable, and a tray is sleeved on the anchor cable.

[0013] The first control valve is a two-position three-way hydraulic manual directional valve, and the second control valve is a three-position three-way hydraulic manual directional valve.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes mechanized operation, eliminating the need for heavy manual anchor picking work, reducing labor intensity and helping to protect the health of operators. When the coal mining machine reaches the tail section, the large amount of coal dust and low visibility generated during tail cutting can be addressed by remote operation via control valves, thereby improving the operator's visibility and significantly reducing the need for personnel to enter dangerous areas, thus greatly reducing the risk of safety accidents. It can effectively pull out anchor cables and anchor bolts, allowing the trays and anchor cable locks to be recycled and reused, improving resource utilization. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] The continuous operation anchor bolt and cable recovery device for fully mechanized mining faces, as shown in Figure 1, includes a motor 1. A brake 2 is installed on one side of the motor 1, and a drum 3 is connected to the other side of the motor 1. The brake 2 is connected to a first control valve 19 through a pipeline, and the motor 1 is connected to a second control valve 20 through a pipeline. A rope presser 7 is fixed on the drum 3, and a traction rope 4 is wound on the drum 3. One end of the traction rope 4 is fixed to the rope presser 7, and the other end of the traction rope 4 is connected to a horseshoe ring 11. The horseshoe ring 11 is connected to a free rope 5, and the free rope 5 is connected to an anchor cable 14 or an anchor bolt 13.

[0030] Referring to Figure 2, the drum 3 includes a sleeve 30, a flange is fixed to the outside of the sleeve 30, and a rope presser 7 is fixed to the side of the flange away from the motor 1. A drum shaft 33 is fixed axially inside the sleeve 30, and a slot 31 is provided on the drum shaft 33. Referring to Figure 3, a motor shaft 35 is provided on the motor 1, and a locking block 34 is fixed on the motor shaft 35. The shape and size of the locking block 34 are adapted to the slot 31, and the locking block 34 is fixed in the slot 31.

[0031] Referring to Figure 1, the motor 1 and the drum 3 are fixed together on the frame 6. A protective plate 8 is installed on the top of the frame 6. The motor 1 has a motor return port 22, a motor forward rotation inlet port 23, and a motor reverse rotation inlet port 24. The motor return port 22, the motor forward rotation inlet port 23, and the motor reverse rotation inlet port 24 are respectively connected to a second control valve 20 through pipelines. The brake 2 has a brake inlet port 21, and the brake inlet port 21 is connected to a first control valve 19 through a pipeline.

[0032] Referring to Figure 4, one end of the traction rope 4 is folded back and fixed by a buckle 10 to form a first pear-shaped ring 9, which is connected to a horseshoe ring 11; both ends of the free rope 5 are folded back and fixed by a buckle 10 to form a second pear-shaped ring 25 and a third pear-shaped ring 26, which are connected to the horseshoe ring 11 and the third pear-shaped ring 26 are connected to the anchor cable 14 or the anchor rod 13.

[0033] The third pear-shaped ring 26 is connected to a lifting eye nut 12, which is connected to the anchor rod 13. The fastening nut 15 is tightened onto the exposed end of the anchor rod 13, and a tray 17 is fitted onto the anchor rod 13.

[0034] Referring to Figure 5, the third pear-shaped ring 26 is connected to a chain link 18, which is sleeved on the anchor cable 14. An anchor cable lock is fixed at the end of the anchor cable 14, and a tray 17 is sleeved on the anchor cable 14.

[0035] Referring to Figures 6 and 7, the first control valve 19 is a two-position three-way hydraulic manual directional valve; referring to Figures 8, 9, and 10, the second control valve 20 is a three-position three-way hydraulic manual directional valve.

[0036] During operation, a hydraulic system is installed on the advance support in the underground roadway. The first control valve 19 and the second control valve 20 are connected to the hydraulic system through pipelines. The motor 1 is selected as the transmission device according to the hydraulic torque and speed requirements. High-pressure emulsion is input through the second control valve 20, driving the internal hydraulic components to move and thus output torque. The hydraulic motor can convert hydraulic energy into mechanical energy to drive the drum 3 to rotate. The brake 2 is a normally closed hydraulic multi-disc brake, which automatically locks the motor shaft 35 when there is no emulsion input. When emulsion is injected, the brake is released, and the motor shaft 35 and the drum 3 can rotate freely. The motor shaft 35, connected to the drum shaft 33, reduces energy loss. The drum shaft 33 receives the driving torque. The drum 3, as the directional storage mechanism for the traction rope 4, winds and releases the traction rope 4. Axial rotation enables the winding and release of the traction rope 4, and its structure ensures stable rope tension and prevents tangling. Both the traction rope 4 and the free rope 5 are made of Φ10mm galvanized anti-corrosion steel wire rope. The frame 6 is easy to install on the advance support in the underground roadway. The rope presser 7 restrains the displacement of the end of the traction rope 4, preventing the rope from coming off during operation. The protective plate 8, made of steel plate, shields against external impact loads. The load protects the motor 1, brake 2, and drum 3 from mechanical damage; the pear-shaped ring serves as a connection point for connection and traction; the buckle 10 secures the free end of the folded-back rope, forming a rope ring structure to ensure the reliability of the rope ring's force; the horseshoe ring 11 is used for rope coupling; the eye nut 12 integrates the functions of a nut and an eye, with the nut thread matching the exposed thread of the anchor rod 13, providing a reliable and easy-to-connect force point; the anchor rod 13 is a steel reinforcement component, anchored inside the coal face, providing support stability through axial anchoring force and suppressing coal deformation; the anchor cable 14 is a steel strand component, deeply anchored inside the coal face. The anchor bolt 13 is tensioned to enhance the stability of the surrounding rock and control deformation displacement. The fastening nut 15 is tightened to the exposed end of the anchor bolt 13 to apply and maintain the preset prestress. The anchor cable lock is a detachable anchor cable lock, consisting of an outer lock anchor ring, an inner lock anchor ring, and a lock clamp, which is locked to the end of the anchor cable 14 to achieve the application and maintenance of the designed tension force. The tray 17 is a perforated circular pressure-bearing steel plate that closely distributes the anchor point pressure against the coal wall to avoid stress concentration. The chain link 18 is equipped with a chain connector adapted to the diameter of the anchor cable 14. After being fitted to the exposed end of the anchor cable 14, it is limited by the anchor cable lock to achieve the connection with the free rope 5.

[0037] The working principle of this utility model:

[0038] A hydraulic system is installed on the advance support in the underground roadway. The first control valve 19 and the second control valve 20 are connected to the hydraulic system through pipelines. When the anchor bolt 13 is retrieved, the third pear-shaped ring 26 is connected to the lifting eye nut 12. The lifting eye nut 12 is screwed into the exposed end of the anchor bolt 13 in the front row of the working face coal wall, thus connecting the third pear-shaped ring 26 to the anchor bolt 13. When the anchor cable 14 is retrieved, the third pear-shaped ring 26 is connected to the chain link 18. The chain link 18 is fitted into the exposed part of the anchor cable 14 in the front row of the working face coal wall. Finally, the chain link 18 is restricted to the exposed part of the anchor cable 14 with the anchor cable lock, thus connecting the third pear-shaped ring 26 to the anchor cable 14.

[0039] The first control valve 19 is configured to control the flow path of the emulsion supplied to the brake 2. The three first oil ports 27 on the first valve body 29 form a hydraulic flow channel. The outer cylindrical surface of the first valve core 28 is precisely fitted with the inner hole of the first valve body 29. The flow channel is sealed or opened by axial relative displacement. The first valve core 28 has two switchable working positions, right and left, which are switched by a handle. When the first valve core 28 is in the right position, as shown in Figure 7, port D and port F are connected. Port D is connected to the brake inlet port 21, and port F is connected to the motor return port 22. Thus, the emulsion inlet passage to the brake 2 is blocked, and the emulsion in the brake 2 can flow back through port F, so that the brake 2 is in the braking state. As shown in Figure 6, when the first valve core 28 is in the left position, port D and port E are connected. Port D is connected to the inlet port of brake 2, and port E is connected to the hydraulic system. Thus, emulsion from the hydraulic system is input to brake 2 via ports E and D, causing brake 2 to be in a released state, allowing motor 1 and its driven drum 3 to rotate. The second control valve 20 is configured to control the emulsion flow path supplied to motor 1 to drive motor 1 to rotate. The three second oil ports 32 on the second valve body 16 form a hydraulic flow channel. The outer cylindrical surface of the second valve core 36 precisely fits the inner hole of the second valve body 16, achieving sealing or opening of the flow channel through axial relative displacement. The second valve core 36 has three switchable working positions: left, middle, and right. The position is switched via a handle. Referring to Figure 9, when the second valve core 36 is in the middle position, port A is blocked. The port is connected to the hydraulic system, thus preventing the emulsion from entering the motor 1, keeping the motor 1 stationary. Referring to Figure 8, when the second valve core 36 is in the left position, port B is blocked, and ports A and C are connected. Port A is connected to the hydraulic system, and port C is connected to the motor forward inlet port 23. Thus, the emulsion from the control system can be supplied to the motor forward inlet port 23 via ports A and C, causing the motor 1 to rotate in the forward direction. Referring to Figure 10, when the second valve core 36 is in the right position, port C is blocked, and ports A and B are connected. Port A is fluidly connected to the hydraulic system, and port B is connected to the motor reverse inlet port 24. Thus, the emulsion from the hydraulic system can be supplied to the motor reverse inlet port 24 via ports A and B, causing the motor 1 to rotate in the reverse direction.

[0040] When the emulsion is input, brake 2 switches to the release state; when the emulsion flows back, brake 2 switches to the braking state. When the motor forward inlet port 23 is connected to the hydraulic system, it supplies emulsion to motor 1 to drive motor shaft 35 to rotate in the forward direction. When the motor reverse inlet port 24 is connected to the hydraulic system, it supplies emulsion to motor 1 to drive motor shaft 35 to rotate in the reverse direction. Motor return port 22 is an integrated return channel. Regardless of whether motor 1 is rotating in the forward or reverse direction, the discharged emulsion flows back to the hydraulic system through this port. When the first control valve 19 switches to the right position, the emulsion of brake 2 flows into motor return port 22 simultaneously.

[0041] By using motor 1 to drive traction rope 4 to generate tension, and operating the first control valve 19 and the second control valve 20, after starting motor 1 to tension traction rope 4, as the coal mining machine advances and causes the coal wall to break and fall, the anchor bolts 13 and anchor cables 14, which should have fallen with the coal flow, are dragged to the side of the roadway under the tension of traction rope 4. This effectively prevents the anchor bolts 13 and anchor cables 14 from entering the coal flow system, thereby avoiding equipment accidents such as scraper breakage, chain breakage, and belt tearing. Compared with the existing technology that requires the application of mechanical force to remove the anchor bolts 13 and anchor cables 14 when the support structure is intact, this device only implements traction and recovery after the coal mining machine advances and causes the coal wall to break and collapse, and the support function of anchor bolts 13 and anchor cables 14 naturally fails. In this process, only the traction function is played, which is not only simple to operate and highly efficient, but also avoids the risks brought about by forced removal.
