Technical Field
[0001] This utility model relates to the field of drilling mechanism technology, specifically a drilling mechanism for a tunneling and anchoring machine. Background Technology
[0002] The drilling rig of a roadheader is a core component of roadheader operations. It is primarily used in mining and tunnel construction to drill holes in rock masses, laying the foundation for subsequent anchoring and support processes. It plays a crucial role in improving construction efficiency and ensuring project safety. Firstly, in mining, precise and efficient drilling is a prerequisite for ore extraction and tunnel excavation, providing strong support for large-scale, mechanized mining. Secondly, in tunnel construction, the performance of the drilling rig directly affects the progress and quality of tunnel construction; reliable drilling ensures the stability of tunnel support structures and reduces construction risks. Furthermore, in geological exploration, the drilling rig can be used to obtain underground rock samples, providing fundamental data for geological analysis and engineering design. In summary, the roadheader... Drilling rigs are indispensable key equipment in underground engineering construction. Their performance directly affects the safety, efficiency, and overall cost control of the construction. However, traditional tunneling and anchoring machine drilling rigs have several drawbacks. First, they are difficult to accurately adapt to drilling requirements at different heights, leading to unstable drilling quality and limiting the scope of construction. Second, rock debris generated during drilling, if not collected in a timely manner, not only affects the cleanliness of the working environment but may also interfere with equipment operation due to debris accumulation, increasing equipment maintenance costs. In addition, the connection methods of some components are not reasonable enough, making the disassembly, maintenance, and replacement of components such as the collection structure cumbersome and reducing the efficiency of equipment operation and maintenance. Therefore, those skilled in the art provide a drilling rig mechanism for tunneling and anchoring machines to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this utility model is to provide a drilling mechanism for a tunneling and anchoring machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A drilling mechanism for a tunneling and anchoring machine includes a base plate, a height adjustment structure, a rotating structure, and a collecting structure. The height adjustment structure is fixedly connected to one side of the top of the base plate, the collecting structure is detachably connected to the height adjustment structure, and the rotating structure is fixedly connected to the top of the height adjustment structure.
[0006] As a further embodiment of this utility model: the height adjustment structure includes a first motor, a lead screw, a fixed frame, a fixed plate, a slide groove, an adjustment frame, a top plate, and a slide. The fixed plate is fixedly connected to the lower part of the fixed frame, and the first motor is fixedly connected to the bottom wall of the fixed frame. The power output shaft of the first motor is fixedly connected to the lead screw. The side of the lead screw away from the first motor passes through one side of the fixed plate and extends into the interior of the fixed frame. The lead screw is rotatably connected to the fixed plate.
[0007] As a further embodiment of this utility model: two sliding grooves are provided on the inner wall of the fixed frame, an adjusting frame is threadedly connected to the lead screw, and sliding brackets corresponding to the sliding grooves are fixedly connected to both sides of the adjusting frame. The sliding brackets are slidably connected to the sliding grooves, and a top plate is fixedly connected to the top of the adjusting frame.
[0008] As a further embodiment of this utility model: the rotating structure includes a fixed shaft, a rotating shaft, and a second motor. The second motor is fixedly connected to the bottom wall of the fixed shaft, and a round shaft is fixedly connected to the power output shaft of the second motor. The round shaft passes through the top of the fixed shaft on the side away from the second motor and is fixedly connected to the rotating shaft. The round shaft is rotatably connected to the fixed shaft.
[0009] As a further embodiment of this utility model: the collecting structure includes a first collecting frame, a card block, a raised button, a connecting groove, a card holder, a baffle, a second collecting frame and a rotating shaft. The rotating shaft is fixedly connected to a groove on one side of the second collecting frame, and the first collecting frame is rotatably connected to the rotating shaft. The baffle is hinged to the side of the second collecting frame away from the first collecting frame.
[0010] As a further embodiment of this utility model: a card holder is fixedly connected to the edge of the second collection frame away from the rotating shaft, and a connecting groove is provided on both sides of the card holder. A card block is fixedly connected to one edge of the first collection frame, and a raised button corresponding to the connecting groove is movably connected to both sides of the card block by a spring, and the raised button is snapped into the connecting groove.
[0011] As a further embodiment of this utility model: the top of the rotating shaft on the rotating structure is embedded with a mounting shaft, and four mounting blocks are fixedly connected at equal intervals on the mounting shaft. Each mounting block is threadedly connected to the rotating shaft by two first screws. Moving wheels are fixedly connected at the four corners of the bottom of the base plate, and the moving wheels are locking wheels. Two push-pull rods are fixedly connected on the top of the base plate away from the height adjustment structure.
[0012] As a further embodiment of this utility model: a connecting shaft is fixedly connected to the top of the embedded shaft, and a mounting plate is fixedly connected to the side of the connecting shaft away from the embedded shaft. A drill bit is threadedly connected to the top of the mounting plate, and a circular plate is fixedly connected to the drill bit. The circular plate is threadedly connected to the mounting plate by six second screws.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In use, firstly, the device is smoothly moved to the target working position by using the cooperation of the moving wheels and push-pull rods. The moving wheels are equipped with a locking function. When the equipment reaches the designated position, the moving wheels are locked to ensure that the entire drilling mechanism will not be displaced during operation, providing a stable foundation for subsequent precise drilling operations. After entering the working stage, the first motor is started, and its power output shaft drives the lead screw to rotate together. Because the adjusting frame is threadedly connected to the lead screw, and the slide is slidably connected to the slide groove, the slide groove guides and constrains the slide, so that the rotational movement of the lead screw can only be converted into the vertical linear movement of the adjusting frame along the slide groove. As the adjusting frame moves up and down, the top plate fixedly connected to it also moves synchronously, thereby driving the rotating structure installed above the top plate and the entire drilling operation components to adjust the height to meet the drilling tasks with different height requirements.
[0015] 2. Start the second motor, and its power output shaft drives the connected circular shaft to rotate. The rotational motion of the circular shaft is transmitted to the rotating shaft, causing the rotating shaft to rotate in a circle around the fixed shaft. The top of the rotating shaft is embedded with a shaft insert, and the shaft insert is firmly connected to the rotating shaft using the first screw on the mounting block. In this way, when the rotating shaft rotates, the shaft insert and the subsequent components connected to it, including the connecting shaft, mounting plate and drill bit, will rotate together with the rotating shaft in the horizontal direction.
[0016] 3. The drill bit is machined with a circular plate with six threaded holes evenly distributed on it. The drill bit is tightly fixed to the top of the mounting plate by the six corresponding second screws. The mounting plate is fixedly connected to one end of the connecting shaft, and the other end of the connecting shaft is fixed to the embedded shaft. When the height adjustment structure and the rotation structure work together to adjust the drill bit to the appropriate height, the second motor is started. The drill bit will then use its high-strength cutting edge to powerfully cut the target rock mass and begin drilling. During the drilling process, as the drill bit continues to drill, the rock mass will be broken into fragments.
[0017] 4. During drilling operations, the generated debris falls into the first and second collection frames below under the influence of gravity. When it is necessary to clean the debris from the collection frames, the operator manually presses the protruding buttons on both sides of the locking block, which are connected by springs. Under pressure, the protruding buttons retract into the locking block against the spring force, causing them to disengage from the connecting slots on both sides of the locking frame. At this time, the latching connection between the first and second collection frames is released, and the operator can easily rotate the first collection frame around the pivot to open it and pour out the debris. In addition, the second collection frame is connected to a baffle on the side away from the first collection frame by a hinge. The operator can also open the baffle to pour out the debris from the second collection frame. If the collection structure malfunctions and requires maintenance, or if different specifications of the collection structure need to be replaced in different operating scenarios, the collection structure can be directly removed from the top plate, making the operation convenient and efficient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This embodiment provides a drilling mechanism for a tunneling and anchoring machine, including a base plate 1, a height adjustment structure 4, a rotating structure 5, and a collecting structure 6. The height adjustment structure 4 is fixedly connected to one side of the top of the base plate 1, and the collecting structure 6 is detachably connected to the height adjustment structure 4. The rotating structure 5 is fixedly connected to the top of the height adjustment structure 4. A pivot 10 is embedded in the top of the rotating shaft 52 on the rotating structure 5. Four mounting blocks 11 are fixedly connected at equal intervals on the pivot 10, and each mounting block 11 is threadedly connected to the rotating shaft 52 by two first screws. Moving wheels 2 are fixedly connected to the four corners of the bottom of the base plate 1, and these moving wheels 2 are locking wheels. Two push-pull rods 3 are fixedly connected to the top of the base plate 1 away from the height adjustment structure 4. Using the cooperation of the moving wheels 2 and the push-pull rods 3, the device is smoothly moved to the target working position. The moving wheels 2 are equipped with a locking function; when the device reaches the designated position, the moving wheels 2 are locked, thereby ensuring the entire drilling mechanism operates smoothly. During the drilling process, no displacement occurs, providing a stable foundation for subsequent precise drilling operations. A connecting shaft 7 is fixedly connected to the top of the embedded shaft 10. A mounting plate 9 is fixedly connected to the side of the connecting shaft 7 away from the embedded shaft 10. A drill bit 8 is threadedly connected to the top of the mounting plate 9. A circular plate is fixedly connected to the drill bit 8, and the circular plate is threadedly connected to the mounting plate 9 by six second screws. The drill bit 8 has a circular plate with six threaded holes evenly distributed on it. The drill bit 8 is tightly fixed to the top of the mounting plate 9 by the six corresponding second screws. The mounting plate 9 is fixedly connected to one end of the connecting shaft 7, and the other end of the connecting shaft 7 is fixed to the embedded shaft 10. When the height adjustment structure 4 and the rotation structure 5 work together to adjust the drill bit 8 to a suitable height, the second motor 53 is started. The drill bit 8 will then use its high-strength cutting edge to powerfully cut the target rock mass and begin drilling operations. During the drilling process, as the drill bit 8 continues to drill, the rock mass will be broken into fragments.
[0028] Example 2
[0029] Reference Figure 1-6This embodiment is based on the previous embodiment, but differs in that the height adjustment structure 4 includes a first motor 41, a lead screw 42, a fixed frame 43, a fixed plate 44, a slide 45, an adjustment frame 46, a top plate 47, and a slide 48. The fixed plate 44 is fixedly connected to the lower part of the fixed frame 43, and the first motor 41 is fixedly connected to the bottom wall of the fixed frame 43. The power output shaft of the first motor 41 is fixedly connected to the lead screw 42. The side of the lead screw 42 away from the first motor 41 passes through one side of the fixed plate 44 and extends into the interior of the fixed frame 43. The lead screw 42 rotates with the fixed plate 44. The inner wall of the fixed frame 43 has two sliding grooves 45. An adjusting frame 46 is threaded onto the lead screw 42. Sliders 48, corresponding to the sliding grooves 45, are fixedly connected to both sides of the adjusting frame 46. The sliders 48 are slidably connected to the sliding grooves 45. A top plate 47 is fixedly connected to the top of the adjusting frame 46. When the first motor 41 is started, its power output shaft drives the lead screw 42 to rotate. Because the adjusting frame 46 is threaded onto the lead screw 42, and the sliders 48 are slidably connected to the sliding grooves 45, the sliding grooves 45 guide and constrain the sliders 48, so that the rotational motion of the lead screw 42 can only be converted into the adjustment frame 46 moving along the sliding grooves. The vertical linear movement in the 45-degree direction causes the top plate 47, which is fixedly connected to it, to move synchronously with the adjustment frame 46. This, in turn, drives the rotating structure 5 installed above the top plate 47 and the entire drilling operation components to adjust their height to meet drilling tasks with different height requirements. The rotating structure 5 includes a fixed shaft 51, a rotating shaft 52, and a second motor 53. The bottom wall of the fixed shaft 51 is fixedly connected to the second motor 53, and the power output shaft of the second motor 53 is fixedly connected to a round shaft. The side of the round shaft away from the second motor 53 passes through the top of the fixed shaft 51 and is fixedly connected to the rotating shaft 52. The round shaft is rotatably connected to the fixed shaft 51. The second motor 53 is started, and its power output shaft drives the round shaft connected to it to rotate. The rotational motion of the round shaft is transmitted to the rotating shaft 52, so that the rotating shaft 52 rotates in a circle around the fixed shaft 51. The top of the rotating shaft 52 is embedded with the insert shaft 10, and the insert shaft 10 is firmly connected to the rotating shaft 52 by the first screw on the mounting block 11. In this way, when the rotating shaft 52 rotates, the insert shaft 10 and the subsequent components connected to it, including the connecting shaft 7, the mounting plate 9 and the drill bit 8, will rotate together with the rotating shaft 52 in the horizontal direction.The collecting structure 6 includes a first collecting frame 61, a locking block 62, a raised button 63, a connecting groove 64, a locking bracket 65, a baffle 66, a second collecting frame 67, and a rotating shaft 68. The rotating shaft 68 is fixedly connected to a groove on one side of the second collecting frame 67, and the first collecting frame 61 is rotatably connected to the rotating shaft 68. A baffle 66 is hinged to the side of the second collecting frame 67 away from the first collecting frame 61. A locking bracket 65 is fixedly connected to the edge of the second collecting frame 67 away from the rotating shaft 68. Connecting grooves 64 are provided on both sides of the locking bracket 65. A locking block 62 is fixedly connected to the edge of one side of the first collecting frame 61. Raised buttons 63, corresponding to the connecting grooves 64, are movably connected to both sides of the locking block 62 via springs, and the raised buttons 63 are snapped into the connecting grooves 64. During drilling operations, the generated debris falls into the first collecting frame 61 and the second collecting frame 67 below under gravity. When cleaning is required... When collecting debris from the collection box, the operator manually presses the raised buttons 63 on both sides of the locking block 62, which are connected by springs. Under pressure, the raised buttons 63 retract into the locking block 62, overcoming the spring force, causing them to disengage from the connecting slots 64 on both sides of the bracket 65. At this time, the snap-fit connection between the first collection box 61 and the second collection box 67 is released, and the operator can easily rotate the first collection box 61 around the pivot 68 to open it and pour out the debris. In addition, the side of the second collection box 67 away from the first collection box 61 is connected to a baffle 66 by a hinge. The operator can also open the baffle 66 to pour out the debris from the second collection box 67. If the collection structure 6 malfunctions and needs maintenance, or if different specifications of the collection structure 6 need to be replaced in different operating scenarios, the collection structure 6 can be directly removed from the top plate 47, making the operation convenient and efficient.
