Description

Technical Field

[0001] This utility model relates to a coal mine drilling equipment, specifically an intelligent anti-outburst and anti-impact drilling rig, belonging to the technical field of coal mine drilling equipment. Background Technology

[0002] Intelligent anti-outburst and anti-impact drilling rigs for coal mines are mechanical equipment used for drilling operations during coal mining. They play an important role in coal mine exploration, ventilation, gas drainage, water injection, and other operations, and are one of the important pieces of equipment for safe production in coal mines. Based on their directional function configuration, coal mine drilling rigs can be divided into two main categories: ordinary drilling rigs and directional drilling rigs.

[0003] However, most existing coal mine drilling rigs have various problems. For example, in the anti-impact pneumatic anchor drilling rig disclosed in announcement number CN222141165U, although the second and first support rods provide support for the pneumatic anchor drilling rig body, making it more stable during use and facilitating control of the drilling depth, ensuring the accuracy of the drilling depth, this technical solution and most current coal mine drilling rigs require anchoring components to fix the machine body in the mine during the initial stage of operation. Current drilling rigs generally use hydraulically driven telescopic rod anchoring components, which use hydraulic cylinders to push the telescopic rod to rigidly abut against the side wall of the mine roadway to fix the machine body. This technology relies on continuous hydraulic pressure to maintain the anchoring force. However, due to the complex working conditions underground (vibration, temperature fluctuations, hydraulic oil contamination), it is easy to cause seal failure and pipeline leakage. Moreover, the axial impact load generated during drilling will aggravate the pressure fluctuation of the hydraulic system, causing intermittent loosening of the anchoring contact surface, which poses certain safety hazards. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing an intelligent anti-outburst and anti-impact drilling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An intelligent anti-outburst and anti-impact drilling rig includes a drilling rig body, support rods and an anchoring mechanism. The support rods are fixed on the drilling rig body and multiple support rods are provided. The anchoring mechanism is fixed on the end of the support rod away from the drilling rig body.

[0007] The anchoring mechanism includes a fixed cylinder, a telescopic cylinder, an anchoring cylinder, a first linkage rod, a second linkage rod, and a drive unit. The fixed cylinder is coaxially fixed to the end of the support rod away from the drilling rig body. The telescopic cylinder is coaxially slidably connected inside the fixed cylinder. The anchoring cylinder is coaxially slidably connected inside the telescopic cylinder. One end of the first linkage rod and the second linkage rod are rotatably connected to each other, and multiple sets are arranged to rotatably connect to each other vertically, forming a scissor-type structure. The bottom of the scissor-type structure is rotatably connected to the fixed cylinder, and the top is rotatably connected to the anchoring cylinder. The drive unit is connected inside the fixed cylinder.

[0008] As a further improvement of this utility model: the scissor-type structure formed by the combination of the first linkage rod and the second linkage rod is arranged in two sets in a symmetrical manner.

[0009] As a further embodiment of this utility model: the drive unit includes a support rod, a linkage block and a lead screw. The support rod is connected between two adjacent sets of scissor-type structures and is located at the intersection of the first linkage rod and the second linkage rod. The linkage block is fixed at the center of the support rod and has a threaded hole through it. The lead screw is rotatably connected to the axis of the fixed cylinder and is threadedly engaged with the threaded hole.

[0010] As a further embodiment of this utility model: the drive unit further includes a worm gear, a servo motor and a worm, the worm gear is coaxially fixed with the lead screw and located at the bottom of the fixed cylinder, the servo motor is fixed at the bottom of the fixed cylinder, the worm is coaxially fixed with the output shaft of the servo motor and the worm meshes with the worm gear.

[0011] As a further improvement of this utility model: the side walls of the telescopic cylinder and the anchoring cylinder are both provided with limiting grooves, and the intersection of the first linkage rod and the second linkage rod is provided with a limiting rod, which is slidably engaged in the limiting groove.

[0012] As a further improvement of this utility model: at least two telescopic cylinders are provided, and multiple shock-absorbing rods are provided on the end of the anchoring cylinder that abuts against the mine shaft.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes an anchoring mechanism, and through a scissor-type linkage structure composed of a first and second linkage rod, and a double self-locking design composed of a screw, worm gear, and worm, completely eliminates the risk of hydraulic system pressure leakage, effectively improving anchoring stability. Furthermore, this structure maintains a locked state even under zero pressure. Simultaneously, the scissor-type structure absorbs axial impact loads through multi-node force dispersion, whereas hydraulic anchors may experience a certain range of displacement and loosening under the same working conditions. Additionally, the screw-driven linkage block uses threaded linkage, which in turn drives the first and second linkage rods to quickly cross-link, enabling rapid adjustment of the anchoring cylinder's position. This design is simple, efficient, and practical. Attached Figure Description

[0021] 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.

[0022] Example 1, as Figures 1 to 5 As shown, an intelligent anti-outburst and anti-impact drilling rig includes a drilling rig body 1, a support rod 2 and an anchoring mechanism 3. The support rod 2 is fixed on the drilling rig body 1 and multiple such rods are provided. The anchoring mechanism 3 is fixed on the support rod 2 at the end away from the drilling rig body 1.

[0023] The anchoring mechanism 3 includes a fixed cylinder 31, a telescopic cylinder 32, an anchoring cylinder 33, a first linkage rod 34, a second linkage rod 35, and a drive unit. The fixed cylinder 31 is coaxially fixed to the support rod 2 at one end away from the drilling rig body 1. The telescopic cylinder 32 is coaxially slidably connected inside the fixed cylinder 31. The anchoring cylinder 33 is coaxially slidably connected inside the telescopic cylinder 32. One end of the first linkage rod 34 and the second linkage rod 35 are rotatably connected to each other, and multiple sets are arranged to rotate and connect to each other vertically, forming a scissor structure. The bottom of the scissor structure is rotatably connected to the fixed cylinder 31, and the top is rotatably connected to the anchoring cylinder 33. The drive unit is connected inside the fixed cylinder 31. The scissor structure formed by the combination of the first linkage rod 34 and the second linkage rod 35 is arranged symmetrically in two sets.

[0024] The drive unit includes a support rod 36, a linkage block 37, and a lead screw 38. The support rod 36 is connected between two adjacent sets of scissor-type structures and is located at the intersection of the first linkage rod 34 and the second linkage rod 35. The linkage block 37 is fixed at the center of the support rod 36 and has a threaded hole through it. The lead screw 38 is rotatably connected to the axis of the fixed cylinder 31 and is threadedly engaged with the threaded hole.

[0025] The drive unit also includes a worm gear 39, a servo motor 310, and a worm 311. The worm gear 39 is coaxially fixed with the lead screw 38 and is located at the bottom of the fixed cylinder 31. The servo motor 310 is fixed at the bottom of the fixed cylinder 31. The worm 311 is coaxially fixed with the output shaft of the servo motor 310 and meshes with the worm gear 39.

[0026] In this utility model, by setting up an anchoring mechanism 3, and then through a scissor-type linkage structure composed of a first linkage rod 34 and a second linkage rod 35, and a double self-locking design composed of a lead screw 38, a worm gear 39 and a worm 311, the risk of hydraulic system pressure leakage is completely eliminated, effectively improving the anchoring stability. Moreover, this structure can still maintain a locked state under zero pressure. At the same time, the scissor-type structure can absorb axial impact loads through multi-node force dispersion, while hydraulic anchors will experience a certain range of displacement and loosening under the same working conditions. In addition, the lead screw 38 drives the linkage block 37 for threaded linkage, thereby driving the first linkage rod 34 and the second linkage rod 35 to quickly cross-link, so that the position of the anchoring cylinder 33 can be quickly adjusted, which is simple, efficient and practical.

[0027] Example 2, as Figures 1 to 5 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0028] Limiting grooves 5 are provided through the side walls of both the telescopic cylinder 32 and the anchoring cylinder 33. A limiting rod 4 is provided at the intersection of the first linkage rod 34 and the second linkage rod 35. The limiting rod 4 is slidably engaged in the limiting groove 5. The limiting rod 4 limits the telescopic cylinder 32 and the anchoring cylinder 33 to prevent them from twisting.

[0029] At least two telescopic cylinders 32 are provided, and multiple shock-absorbing rods are provided on the end of the anchor cylinder 33 that abuts against the mine shaft. By setting the shock-absorbing rods, the anchor cylinder 33 can obtain a certain shock-absorbing and buffering effect when it abuts against the inner wall of the mine shaft, so as to prevent the support rod 2 and the anchoring mechanism 3 from being bent due to excessive force.

[0030] When using this coal mine drilling equipment, first move the drilling rig body 1 to a suitable position, then start the servo motor 310 to drive the worm gear 311 to rotate. At this time, the worm wheel 39 engages and drives the lead screw 38 to rotate. The linkage block 37 is threaded on the lead screw 38, and through the support rod 36, it drives the first linkage rod 34 and the second linkage rod 35 to cross and link with each other, thereby causing the telescopic cylinder 32 and the anchoring cylinder 33 to slide respectively until one end of the anchoring cylinder 33 abuts against the inner wall of the mine, and the drilling rig body 1 is anchored and locked.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
