Description

Technical Field

[0001] This utility model relates to the field of anchoring operation technology, and in particular to an integrated drilling and pre-tightening anchor support device. Background Technology

[0002] Before coal mining operations, a coal seam roadway needs to be excavated to divide the planned coal mining area. During the excavation of the coal seam roadway, the complex geology of the mine leads to poor stability of the coal seam, making accidents such as roof falls and coal spills prone to occur, endangering the safety of operators. Therefore, anchoring operations are even more crucial than the roadway excavation itself. Currently, coal roadway excavation equipment is equipped not only with a roadway excavation system but also with a roadway support system. During a stage of excavation, the cutting system at the front end of the integrated tunneling and anchoring machine performs excavation work while the support system at the rear end simultaneously performs anchoring operations. For coal roadways where anchoring work has not yet been completed, the geological structure near the working face is relatively unstable, resulting in a lower overall safety factor. Therefore, equipment capable of simultaneous excavation and anchoring is widely used in the field of coal roadway excavation. However, when carrying out anchoring operations, the drilling of anchor bolts, installation of anchoring agents, and pre-tightening vary depending on the coal roadway, and the construction difficulty and working conditions are different. This makes it difficult to maintain a consistent standard of support efficiency in the coal roadway. Therefore, improving the efficiency of coal roadway anchoring operations is the key to coal roadway excavation work.

[0003] Integrated roadheader-anchor (TBA) machines are widely used equipment in coal mine roadway excavation. Modern TBA machines can achieve one-time roadway formation and simultaneous excavation and anchoring, significantly improving roadway excavation efficiency. Existing TBA machines are equipped with anchor bolting machines on both sides of the middle or rear of the machine. These machines typically drill holes in the side walls of the coal seam roadway and insert anchor bolts into the walls, thereby improving the overall stability of the coal roadway. For anchoring operations, taking coal mine roadway support as an example, the anchor bolt support process is as follows: First, holes are drilled in the rock walls on both sides and above the coal roadway using drill rods; second, anchoring agent is manually inserted into the drilled holes, and the anchor bolts are placed in and stirred; finally, after the anchoring agent has cured, the anchor bolts are pre-tightened. However, in the past, due to the differences in coal seam geology, the manual installation of anchoring agent was difficult and time-consuming, resulting in low support efficiency. Furthermore, drilling, installing anchoring agent, and pre-tightening of anchor bolts require different tools, and disassembling and installing tools takes a considerable amount of time to complete the anchoring operation.

[0004] From the perspective of current technology, the anchor bolting machine on the integrated tunneling and anchoring machine has a relatively limited function and lacks the ability to quickly switch between multiple tasks such as drilling, installing anchoring agents, and pre-tightening. This results in reduced anchoring efficiency, increased labor intensity for workers, and difficulty in achieving rapid tunnel excavation. Therefore, for coal roadways with complex geological conditions, existing equipment is currently unable to quickly achieve anchoring work.

[0005] Therefore, it is necessary to provide a new integrated drilling and pre-tightening anchor bolt support device to solve the above-mentioned technical problems. Utility Model Content

[0007] To achieve the above objectives, the present invention proposes an integrated drilling and pre-tightening anchor bolt support device, comprising a base, a drive mechanism, a rotating shaft, a grouting mechanism, and an anchoring mechanism. The drive mechanism is mounted on the base; the rotating shaft is rotatably mounted on the base and connected to the output end of the drive mechanism, and an axially oriented through hole is formed within the rotating shaft; the grouting mechanism is mounted on the base and communicates with a supply device at the first end of the through hole; the anchoring mechanism includes an anchor bolt and a pre-tightening nut, one end of the anchor bolt forming a limiting block; the pre-tightening nut is sleeved on the anchor bolt and threadedly connected to the anchor bolt, and the pre-tightening nut is fixedly mounted at the second end of the through hole.

[0008] Optionally, the grouting mechanism includes a connecting seat and a grouting cylinder, the connecting seat being disposed on the base; the grouting cylinder being disposed on the connecting seat, and the grouting cylinder passing through the connecting seat and communicating with the through hole.

[0009] Optionally, the grouting cylinder includes a grouting sleeve, a grouting component, a guide sleeve, and a hydraulic assembly. The first end of the grouting sleeve is fixedly mounted on the connecting seat, and the second end is sealed by the guide sleeve. A first cavity and a second cavity are formed inside the grouting sleeve. The grouting sleeve has two oil injection ports that communicate with the first cavity and the second cavity, respectively. A piston is provided on the outer periphery of the grouting component. The grouting component slides through the guide sleeve, the grouting sleeve, and the connecting seat, and is slidably mounted in the through hole. The piston is slidably mounted in the second cavity. The hydraulic assembly is connected to the two oil injection ports, respectively.

[0010] Optionally, the connecting seat includes a mounting part and a sealing part connected to each other. The mounting part is disposed on the base and has a clearance groove, which is correspondingly disposed to the rotating shaft. The sealing part has a through hole communicating with the clearance groove. The through hole is slidably engaged with the grouting component. The sealing part is fixedly disposed inside the first end of the grouting sleeve. The grouting cylinder also includes a sealing element. The sealing element is disposed between the grouting component and the through hole, and the sealing element is also disposed between the sealing part and the inner wall of the grouting sleeve.

[0011] Optionally, the grouting component is provided with one or more grouting channels arranged axially, and the two ends of the grouting channels are respectively connected to the through hole and the supply device.

[0012] Optionally, the grouting mechanism further includes a liquid dispensing component, which is detachably connected to the end of the grouting component away from the through hole; the liquid dispensing component is provided with a liquid dispensing chamber corresponding to the grouting channel, and each liquid dispensing chamber is provided with a grouting port for communicating with the corresponding supply equipment.

[0013] Optionally, the drill-injection pre-tightening integrated anchor bolt support device further includes a rod body adapter, which is detachably connected to the rotating shaft. The rod body adapter is provided with an adapter hole that matches the shape of the pre-tightening nut, and the pre-tightening nut is fixedly installed in the adapter hole.

[0014] Optionally, the driving mechanism includes a driving member, a driving wheel, and a driven wheel. The driving member is disposed on the base; the driving wheel is connected to the output shaft of the driving member; the driven wheel is fixedly sleeved on the outer circumference of the rotating shaft, and the driven wheel meshes with the driving wheel.

[0015] Optionally, the base includes a base plate, a mounting plate, a reinforcing plate, and a cover plate. The base plate is perpendicular to the mounting plate, and the reinforcing plate is connected between the base plate and the mounting plate. The cover plate is detachably disposed on the side of the mounting plate away from the reinforcing plate, and a mounting cavity is formed between the cover plate and the mounting plate. The driving wheel and the driven wheel are both disposed in the mounting cavity. The rotating shaft passes perpendicularly through the reinforcing plate and the mounting plate, and is rotatably connected to the reinforcing plate and the mounting plate respectively through bearings.

[0016] In this utility model's technical solution, during anchoring operations, the anchoring mechanism is installed within the through hole of the rotating shaft, and the pre-tightening nut is fixedly engaged with the rotating shaft. The anchor rod is pressed against the rock wall surface. During drilling operations, the drive mechanism drives the pre-tightening nut to rotate through the rotating shaft until it abuts against the limiting block at the end of the anchor rod. The pre-tightening nut and the anchor rod are locked together as a whole, thereby driving the anchor rod to rotate to achieve drilling operations on the rock wall. Simultaneously, the grouting mechanism delivers water supplied by the supply equipment through the through hole to the gap between the anchor rod and the rock wall to clean the coal slag generated during drilling. After drilling is completed, the drive mechanism is turned off, and the grouting mechanism delivers anchoring agent supplied by the supply equipment to the gap between the anchor rod and the rock wall to stabilize the anchor rod. After the anchoring agent has solidified, the drive mechanism is started to rotate in the opposite direction to drive the pre-tightening nut to move along the anchor rod towards the rock wall until the pre-tightening nut is pressed against the rock wall surface, completing the pre-tightening operation. This invention integrates the three essential actions required for anchoring operations—anchor drilling, anchor installation, and anchor pre-tightening—to enable efficient completion of these processes, thereby improving the efficiency of coal roadway support operations. This ensures the anchoring operation of the roadway, guarantees the overall stability of the coal roadway, and reduces safety hazards during tunneling. Attached Figure Description

[0030] This utility model proposes an integrated drilling and pre-tightening anchor bolt support device, which aims to solve the problem of low operating efficiency of existing integrated drilling and pre-tightening anchor bolt support devices.

[0031] like Figure 1As shown, the drill-injection pre-tightening integrated anchor bolt support device includes a base 1, a drive mechanism 2, a rotating shaft 3, a grouting mechanism 4, and an anchoring mechanism. The drive mechanism 2 is mounted on the base 1. The rotating shaft 3 is rotatably mounted on the base 1 and connected to the output end of the drive mechanism 2, and an axially oriented through hole 3.1 is formed inside the rotating shaft 3. The grouting mechanism 4 is mounted on the base 1 and is connected to the first end of the through hole 3.1 and connected to the supply equipment. The anchoring mechanism includes an anchor bolt and a pre-tightening nut. One end of the anchor bolt forms a limiting block. The pre-tightening nut is sleeved on the anchor bolt and threadedly connected to the anchor bolt, and the pre-tightening nut is fixedly mounted at the second end of the through hole 3.1. During anchoring operations, the anchoring mechanism is installed in the through hole 3.1 of the rotating shaft 3, and the pre-tightening nut is fixedly engaged with the rotating shaft 3. The anchor rod is pressed against the rock wall surface. During drilling operations, the drive mechanism 2 drives the pre-tightening nut to rotate through the rotating shaft 3 until it abuts against the limiting block at the end of the anchor rod. The pre-tightening nut and the anchor rod are locked together as a whole, thereby driving the anchor rod to rotate to realize the drilling operation on the rock wall. At the same time, the grouting mechanism 4 delivers water supplied by the supply equipment through the through hole 3.1 to the gap between the anchor rod and the rock wall to clean the coal slag generated during drilling. After drilling is completed, the drive mechanism 2 is turned off, and the grouting mechanism 4 delivers the anchoring agent supplied by the supply equipment to the gap between the anchor rod and the rock wall to stabilize the anchor rod. After the anchoring agent has solidified, the drive mechanism 2 is started to rotate in the opposite direction to drive the pre-tightening nut to move along the anchor rod towards the rock wall until the pre-tightening nut is pressed against the rock wall surface, completing the pre-tightening operation. This embodiment integrates the three essential actions required for anchoring operations—anchor drilling, anchor installation, and anchor pre-tightening—to enable efficient completion of these processes, thereby improving the efficiency of coal roadway support operations. This ensures the anchoring operation of the roadway, guarantees the overall stability of the coal roadway, and reduces safety hazards during tunneling.

[0032] See also Figure 2 The grouting mechanism 4 includes a connecting seat 4.1 and a grouting cylinder 4.2. The connecting seat 4.1 is mounted on the base 1; the grouting cylinder 4.2 is mounted on the connecting seat 4.1 and passes through the connecting seat 4.1 to communicate with the through hole 3.1. The grouting cylinder 4.2 is mounted on the base 1 via the connecting seat 4.1 and communicates with the through hole 3.1, so as to deliver water into the through hole 3.1 to clean coal slag during drilling, realizing simultaneous drilling and coal slag cleaning; or after drilling is completed, anchoring agent is introduced through the through hole 3.1 to facilitate anchoring operations.

[0033] Specifically, the grouting cylinder 4.2 includes a grouting sleeve 4.2.1, a grouting component 4.2.2, a guide sleeve 4.2.3, and a hydraulic assembly. The first end of the grouting sleeve 4.2.1 is fixedly mounted on the connecting seat 4.1, and the second end is sealed by the guide sleeve 4.2.3. A first cavity C1 and a second cavity C2 are formed inside the grouting sleeve 4.2.1. Two oil injection ports C3 are provided on the grouting sleeve 4.2.1, which are respectively connected to the first cavity C1 and the second cavity C2. A piston D1 is provided on the outer periphery of the grouting component 4.2.2. The grouting component 4.2.2 slides through the guide sleeve 4.2.3, the grouting sleeve 4.2.1, and the connecting seat 4.1, and is slidably mounted in the through hole 3.1. The piston D1 is slidably mounted in the second cavity C2. The hydraulic assembly is respectively connected to the two oil injection ports C3. Two oil injection ports C3 are connected to the hydraulic assembly, allowing the hydraulic assembly to adjust the oil in the first cavity C1 and the second cavity C2 to drive the piston D1 and move the grouting component 4.2.2. The guide sleeve 4.2.3 can both seal and guide the grouting component 4.2.2. After the anchoring agent is mixed and cured, the hydraulic assembly drives the grouting component to retract along its length, providing working space for the pre-tightening of the anchor rod, and then completing the pre-tightening of the anchor rod. The anchoring agent is directly delivered to the rock wall borehole by the grouting component 4.2.2, reducing the construction difficulty caused by the relatively broken rock wall of the coal roadway or the unevenness of the borehole wall, and improving production efficiency.

[0034] Furthermore, the connecting seat 4.1 includes a mounting part 4.1.1 and a sealing part 4.1.2 connected to each other. The mounting part 4.1.1 is disposed on the base 1 and has a relief groove A1, which is correspondingly disposed with the rotating shaft 3. The sealing part 4.1.2 has a through hole B1 communicating with the relief groove A1. The through hole B1 is slidably engaged with the grouting component 4.2.2. The sealing part 4.1.2 is fixedly disposed in the first end of the grouting sleeve 4.2.1. The grouting cylinder 4.2 also includes a sealing component 4.2.4. A sealing component 4.2.4 is disposed between the grouting component 4.2.2 and the through hole B1, and a sealing component 4.2.4 is also disposed between the sealing part 4.1.2 and the inner wall of the grouting sleeve 4.2.1. The connecting seat 4.1 not only allows for clearance of the rotating shaft 3 but also facilitates the installation of the grouting sleeve 4.2.1. Furthermore, the sealing element 4.2.4 ensures the sealing between the first cavity C1 and the clearance groove A1, as well as the overall sealing of the grouting sleeve 4.2.1. A shaft end baffle 7 for limiting the rotating shaft 3 is also provided between the mounting part 4.1.1 and the base 1. In this embodiment, the sealing element 4.2.4 can be an O-ring, a rod sealing ring E3, or a dustproof ring E2. An O-ring is used to seal between the sealing part 4.1.2 and the inner wall of the grouting sleeve 4.2.1. A dustproof ring E2, an O-ring, and a rod sealing ring E3 are sequentially arranged in a direction away from the rotating shaft 3 between the through hole B1 and the grouting element 4.2.2, further enhancing the sealing performance.

[0035] Furthermore, the grouting component 4.2.2 is provided with one or more axially arranged grouting channels D2, with both ends of the grouting channel D2 connected to the through hole 3.1 and the supply equipment, respectively. Each grouting channel D2 works independently to meet the water supply and different anchoring agent delivery requirements during anchoring operations. Separate delivery of different anchoring agents avoids premature solidification of the anchoring agents and blockage of the grouting channel D2.

[0036] See also Figure 3 The grouting mechanism 4 also includes a liquid dispensing component 4.3, which is detachably connected to the end of the grouting component 4.2.2 away from the through hole 3.1. The liquid dispensing component 4.3 has a liquid dispensing chamber 4.3.1 corresponding to the grouting channel D2, and each liquid dispensing chamber 4.3.1 has a grouting port 4.3.2 for communicating with the corresponding supply equipment. The liquid dispensing component 4.3 is designed to facilitate the simultaneous supply of water and anchoring agent, further improving operational efficiency.

[0037] In addition, the drilled and pre-tightened integrated anchor bolt support device also includes a rod body adapter 5, which is detachably connected to the rotating shaft 3. The rod body adapter 5 has an adapter hole that matches the shape of the pre-tightening nut, and the pre-tightening nut is fixedly installed in the adapter hole. The rod body adapter 5 facilitates the connection between the anchor bolt mechanism and the rotating shaft 3, and the corresponding rod body adapter 5 can be replaced according to the type of anchor bolt used, thus improving the applicability of the device.

[0038] In this embodiment, the drive mechanism 2 includes a drive component 2.1, a driving wheel 2.2, and a driven wheel 2.3. The drive component 2.1 is mounted on the base 1; the driving wheel 2.2 is connected to the output shaft of the drive component; the driven wheel 2.3 is fixedly sleeved on the outer circumference of the rotating shaft 3, and meshes with the driving wheel 2.2. In this embodiment, the drive component 2.1 is a hydraulic motor, which can rotate forward and reverse, and drives the rotating shaft 3 to rotate in both directions via the driving wheel 2.2 and the driven gear, facilitating drilling and pre-tightening operations.

[0039] See also Figure 4The base 1 includes a base plate 1.1, a mounting plate 1.2, a reinforcing plate 1.3, and a cover plate 1.4. The base plate 1.1 is perpendicular to the mounting plate 1.2, and the reinforcing plate 1.3 connects the base plate 1.1 and the mounting plate 1.2. The cover plate 1.4 is detachably mounted on the side of the mounting plate 1.2 away from the reinforcing plate 1.3, and a mounting cavity 1.5 is formed between the cover plate 1.4 and the mounting plate 1.2. The driving wheel 2.2 and the driven wheel 2.3 are both located in the mounting cavity 1.5. The rotating shaft 3 passes perpendicularly through the reinforcing plate 1.3 and the mounting plate 1.2, and is rotatably connected to the reinforcing plate 1.3 and the mounting plate 1.2 respectively via bearings 6. The combination of the base plate 1.1, the mounting plate 1.2, and the reinforcing plate 1.3 ensures the structural strength of the base 1, and the cover plate 1.4 protects the driving wheel 2.2, the driven wheel 2.3, and the rotating shaft 3.

[0040] When the equipment needs to perform anchoring operations, the anchor rod is pre-fixed on the rod body adapter 5. The drive mechanism 2 drives the rotating shaft 3 to rotate forward to perform the anchor rod drilling work. At the same time, the grouting cylinder 4.2 moves the injection component horizontally in the direction of anchor rod drilling, and delivers water through the grouting channel D2 to the gap between the anchor rod and the rock wall. After drilling is completed, the drive mechanism 2 is paused, and the anchoring agent is delivered through the grouting channel D2 into the hole drilled by the anchor rod to complete the installation of the anchoring agent. After the anchoring agent has cured, the injection component moves horizontally away from the drilling hole through the grouting cylinder 4.2 to reserve working space for anchor rod pre-tightening. When the injection component reaches the predetermined position, the drive mechanism 2 is restarted to drive the rotating shaft 3 to rotate in reverse, tighten the nut on the anchor rod, and complete the anchor rod pre-tightening work.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
