Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of drilling mechanisms, and more particularly, to an electric drilling mechanism. Background Art

[0002] In coal mining operations, the construction and maintenance of roadways are crucial. In existing coal mine roadways, the inner walls are uneven. During the operation of anchor rod drilling, it is necessary to use a tightening member to press relevant equipment against the inner wall of the roadway to provide support for the anchor rod drilling. The unevenness of the inner wall of the roadway makes it difficult for the tightening member to exert a stable force, and unstable situations such as shaking and deviation may occur during the process of pressing against the inner wall of the roadway. As a result, the anchor rod cannot maintain a vertical or predetermined drilling direction during drilling, and the phenomenon of drilling crooked occurs. Drilling the anchor rod crooked not only reduces the effectiveness of support and fails to fully exert the reinforcement effect of the anchor rod on the roadway, but also may cause a series of safety hazards. Summary of the Invention

[0003] To overcome the above defects, embodiments of the present disclosure provide an electric drilling mechanism, which solves the technical problem in the prior art that due to the unevenness of the coal mine roadway, the tightening member fails to press against the inner wall of the roadway, resulting in the anchor rod being drilled crooked.

Detailed implementation manners

[0018] The present disclosure will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than limiting the present disclosure.

[0019] To make the drawings concise, only the parts related to the disclosure are schematically shown in each drawing, and they do not represent the actual structure of the product.

[0023] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0024] Such as Figures 1 to 8As shown, it shows an electric drilling mechanism in an embodiment of the present disclosure. The mounting shell 2 is slidably and rotatably arranged on the base frame 1 through a slide rail structure, or a guide rod is designed on the base frame 1, and the mounting shell 2 slides and rotates along the guide rod. Its sliding on the base frame 1 is realized through driving devices such as motors and lead screws to approach or move away from the wall. The grinding knife 3 is slidably arranged on the mounting shell 2 through a guide rail or a chute, and it can be pushed to slide on the mounting shell 2 through a cylinder, an electric push rod, etc., so that it slides into or out of the interior of the mounting shell 2. When the grinding knife 3 slides out of the mounting shell 2, the mounting shell 2 drives its rotation through transmission means such as a motor, so that the grinding knife 3 contacts the wall, and the grinding knife 3 grinds the wall. During the grinding process, the mounting shell 2 continuously approaches the wall. After the grinding is completed, the grinding knife 3 slides into the mounting shell 2 for hiding, and the mounting shell 2 continues to approach the wall, and uses its surface to tightly press against the ground wall. In actual operation, the grinding knife 3 can be adjusted according to different positions and angles of the wall to ensure the accuracy of grinding and drilling work. All actuating mechanisms in the present disclosure are driven by components such as electric cylinders, servo motors, and stepping motors, which can effectively prevent excessive loss during power transmission. The power medium is electricity, which has overload and leakage protection functions, high safety, stable operation, and simple structure, small volume, and is easier to maintain compared to hydraulic and pneumatic systems. The overall structure is light in weight, and each working mechanism is highly centralized, with a small overall size. This structure enables the surface of the wall to be ground before drilling, removing uneven parts on the wall surface, and ensuring the accuracy and stability of subsequent drilling operations. The mounting shell 2 tightly presses against the wall to reduce the shaking during drilling and improve the drilling quality.

[0025] As Figure 2 shown, a plurality of knife-through holes 21 on the mounting shell 2 are arranged at intervals along the circumference and communicate with the interior. The number and size of the knife-through holes 21 are matched with the grinding knife 3. The edge of the mounting plate 4 contacts the inner wall of the mounting shell 2, and the inner wall of the mounting shell 2 provides a sliding track for the mounting plate 4. One end of a plurality of grinding knives 3 is fixedly installed on the mounting plate 4, and by pushing the mounting plate 4 to slide in the mounting shell 2, the grinding knives 3 are driven to slide into or out of the knife-through holes 21. When the grinding knife 3 slides out of the mounting shell 2, the mounting shell 2 drives its rotation through transmission means such as a motor and gear transmission. A driving gear is installed on the output shaft of the motor, and a driven gear is installed on the mounting shell 2. The driving gear meshes with the driven gear. When the motor rotates, the driving gear drives the driven gear to rotate, thereby driving the rotation of the mounting shell 2 and the grinding knife 3.

[0026] During the grinding process, the installation shell 2 continuously approaches the wall. The position of the installation shell 2 can be monitored in real time by a displacement sensor arranged on the base frame 1, and the signal is fed back to the control system. The control system adjusts the rotation speed of the motor and the movement of the lead screw according to the feedback signal to ensure that the installation shell 2 approaches the wall at an appropriate speed and pressure. After the grinding is completed, the grinding tool 3 slides into the installation shell 2 for hiding, and the installation shell 2 continues to approach the wall, and uses its surface to tightly press against the ground wall.

[0027] When encountering unevenness, protrusions, depressions, etc. on the wall surface, the grinding tool 3 grinds the wall surface flat. The function that the grinding tool 3 slides into the installation shell 2 for hiding can protect the grinding tool 3 when not in use, extend its service life, and at the same time avoid accidental injuries to the operator caused by the grinding tool 3. The function of the installation shell 2 pressing tightly against the wall can effectively reduce the shaking during drilling, improve the quality of drilling, make the drilled holes more vertical, and meet the construction requirements. The tool insertion hole 21 provides a sliding path for the grinding tool 3 to ensure that the grinding tool 3 can slide into and out of the installation shell 2. The mounting plate 4 enables multiple grinding tools 3 to move synchronously.

[0028] Multiple grinding tools 3 are arranged at circumferential intervals on the installation shell 2. When the mounting plate 4 drives the grinding tools 3 to slide out of the tool insertion holes 21, the multiple grinding tools 3 can simultaneously grind the wall surface. Compared with a single grinding tool 3, the grinding coverage area is greatly increased, thereby improving the grinding efficiency.

[0029] Since the grinding tools 3 are evenly distributed along the circumference, during the grinding process, the wall surface can be ground more evenly, avoiding the situation of excessive or insufficient local grinding, and improving the grinding quality.

[0030] One end of the grinding tool 3 is installed on the mounting plate 4 by welding or integrally formed, and the other end slides in the tool insertion hole 21. This installation method ensures the stability of the grinding tool 3 during the working process.

[0031] As Figure 3 shown, several first clamping protrusions 41 on the mounting plate 4 are arranged at intervals along the sliding direction of the grinding tool 3. The runner 5 is rotatably arranged in the installation shell 2 through a bearing. The clamping grooves 51 on the runner 5 are arranged at circumferential intervals. When the runner 5 rotates, the first clamping protrusions 41 are clamped into the clamping grooves 51. As the runner 5 continues to rotate, it drives the mounting plate 4 to slide in the installation shell 2, thereby realizing the sliding in and out of the grinding tool 3.

[0032] Through the cooperation of the first clamping protrusions 41 and the clamping grooves 51, the rotational movement of the runner 5 is converted into the linear sliding movement of the mounting plate 4. This transmission method has a simple structure and is easy to maintain, and can also control the sliding distance and position of the grinding tool 3.

[0033] Through the cooperation of the rotating wheel 5 with the first engaging protrusion 41 and the second engaging protrusion 61, the reverse sliding of the grinding tool 3 and the supporting top piece 6 is realized. During the grinding process, the grinding tool 3 can grind the wall, while the supporting top piece 6 can be retracted. After grinding, the supporting top piece 6 slides out of the sliding hole 22 and can penetrate into the wall for further support, enhancing the fixing effect on the wall and providing a more stable foundation for subsequent drilling operations. The cooperation of the second engaging protrusion 61 with the engaging groove 51 and the cooperation of the first engaging protrusion 41 with the engaging groove 51 together constitute a transmission structure. This structure can convert the rotation of the rotating wheel 5 into the linear sliding of the grinding tool 3 and the supporting top piece 6, and during the movement, the connection between each component is tight, reducing the risk of failure caused by loosening or misalignment. The second engaging protrusions 61 are arranged at equal intervals along the sliding direction of the supporting top piece 6 and cooperate with the engaging grooves 51 on the rotating wheel 5, enabling the sliding distance and position of the supporting top piece 6 to be controlled. Similarly, the first engaging protrusion 41 can also control the movement of the grinding tool 3. This ensures that the grinding tool 3 and the supporting top piece 6 can reach the predetermined positions at different working stages.

[0034] The supporting top piece 6 cannot completely slide out of the sliding hole 22. One end of the supporting tip located inside the mounting shell 2 has an engaging boss, and the engaging protrusion can be stuck around the sliding hole 22 to prevent the supporting top piece 6 from completely detaching from the mounting shell 2. As Figure 4 shown, the sliding hole 22 on the mounting shell 2 provides a sliding channel for the supporting top piece 6. A number of second engaging protrusions 61 on the supporting top piece 6 are arranged at intervals along its sliding direction, and the first engaging protrusion 41 and the second engaging protrusions 61 are respectively located on both sides of the rotating wheel 5. When the rotating wheel 5 rotates, the engaging groove 51 cooperates with the first engaging protrusion 41 and the second engaging protrusions 61, making the sliding directions of the supporting top piece 6 and the grinding tool 3 opposite. During the grinding process, the grinding tool 3 slides out of the mounting shell 2 for grinding, and the supporting top piece 6 slides into the sliding hole 22 for retraction. After grinding, the grinding tool 3 slides into the mounting shell 2 for retraction, and the end face of the mounting shell 2 is in direct contact with the ground wall, increasing the supporting area and making the support more stable. The supporting top piece 6 penetrates into the wall to enhance the supporting strength.

[0035] The design of reverse sliding enables the supporting top piece 6 to slide in when the grinding tool 3 slides out for grinding operations, playing a role in assisting the fixation of the mounting shell 2; after grinding, the grinding tool 3 slides in and the supporting top piece 6 slides out, enabling further fixation or drilling operations on the wall.

[0036] After the spacer block 7 slides out of the tool insertion hole 21, it promptly slides into the space between the mounting plate 4 and the inner wall of the mounting shell 2 to form a block, preventing the grinding tool 3 from accidentally sliding back into the tool insertion hole 21 due to the reaction force of the wall. This ensures that the grinding tool 3 always remains in the working position during the grinding process, avoiding uneven grinding or grinding interruption caused by the position change of the grinding tool 3, thereby improving the grinding quality. The one-way swing design of the first clamping protrusion 41 and the second clamping protrusion 61 enables the first clamping protrusion 41 and the second clamping protrusion 61 to be reset through a torsion spring. When not under force, a structure similar to a rack is formed by the cooperation between several first clamping protrusions 41. The principle of several second clamping protrusions 61 is the same, which allows the runner 5 to continue rotating without interference with the first clamping protrusion 41 and the second clamping protrusion 61 during the sliding-out process of the grinding tool 3, and the first clamping protrusion 41 and the second clamping protrusion 61 can also be reset. When the first clamping protrusion 41 and the second clamping protrusion 61 encounter a large resistance, the runner 5 idles by swinging, avoiding excessive wear of the clamping protrusions, the clamping groove 51, and the runner 5 itself caused by forced transmission. The sliding of the spacer block 7 is automatically triggered by the sliding-out action of the grinding tool 3 without manual intervention, realizing the automation of equipment operation.

[0037] As Figure 4 , Figure 6 and Figure 7 shown, the first clamping protrusion 41 and the second clamping protrusion 61 are respectively arranged with one-way swing on the mounting plate 4 and the supporting top piece 6, and the swing structure is realized through a spring and a rotating shaft. The first clamping protrusion 41 and the second clamping protrusion 61 can maintain a stable position during normal operation. At the same time, when the grinding tool 3 slides out of the tool insertion hole 21 and is in the grinding state, it prevents the runner 5 from interfering with the first clamping protrusion 41 and the second clamping protrusion 61, and the first clamping protrusion 41 and the second clamping protrusion 61 can swing when affected by the runner 5. Since there is no supporting structure to support the grinding tool 3 after the first clamping protrusion 41 and the second clamping protrusion 61 swing, the grinding tool 3 slides backward after being subjected to the reaction force of the wall during the grinding process. The present disclosure designs the spacer block 7, and the spacer block 7 is slidably arranged in the mounting shell 2 through a guide rail or a chute. After the grinding tool 3 slides out of the tool insertion hole 21, the first clamping protrusion 41 and the second clamping protrusion 61 swing under the action of the runner 5. At this time, the runner 5 idles, preventing interference between the runner 5 and the first clamping protrusion 41 and the second clamping protrusion 61. To prevent the grinding tool 3 from sliding backward into the mounting shell 2 during grinding and affecting the grinding effect, at this time, the spacer block 7 slides into the space between the mounting plate 4 and the inner wall of the mounting shell 2 under the action of a driving device such as a cylinder or an electric push rod, preventing the grinding tool 3 from sliding into the tool insertion hole 21.

[0038] The spacer block 7 ensures the stability of the grinding tool 3 during the grinding process. Through the swinging of the first clamping protrusion 41 and the second clamping protrusion 61 and the cooperation of the spacer block 7, it can prevent the grinding tool 3 from accidentally sliding into the tool passing hole 21, ensuring the continuous and stable progress of the grinding work. This not only improves the quality and efficiency of grinding, but also reduces equipment failures and safety hazards caused by abnormal sliding of the grinding tool 3. The first clamping protrusion 41 and the second clamping protrusion 61 are respectively arranged on the mounting plate 4 and the supporting top member 6 to swing unidirectionally, and the swinging structure can be realized by springs, rotating shafts, etc.

[0039] As Figure 5 shown, one end of the connecting rod 8 is hinged to the mounting plate 4 through a hinge shaft, and the other end is slidably arranged on the spacer block 7 through a slider, and the slider can slide on the guide rail of the spacer block 7 along the sliding direction of the grinding tool 3. The first elastic member 9 is usually a spring, one end of which is fixed on the inner wall of the mounting shell 2, and the other end is fixed on the spacer block 7. When the grinding tool 3 slides into the tool passing hole 21, the elastic force provided by the first elastic member 9 causes the spacer block 7 to slide out between the mounting plate 4 and the inner wall of the mounting shell 2. When the runner 5 rotates and the grinding tool 3 slides out of the tool passing hole 21, the mounting plate 4 causes the first elastic member 9 to elongate through the action of the connecting rod 8, and further causes the spacer block 7 to be clamped between the inner wall of the mounting shell 2 and the grinding tool 3.

[0040] The cooperation of the connecting rod 8 and the first elastic member 9 enables the spacer block 7 to automatically adjust its position according to the sliding state of the grinding tool 3, realizing the automatic operation of the mechanism, reducing manual intervention, and improving work efficiency.

[0041] The setting of the connecting rod 8 and the first elastic member 9 further improves the automatic operation mechanism of the equipment. The sliding out and retracting actions of the grinding tool 3 can automatically trigger the corresponding movement of the spacer block 7 through the connecting rod 8, without additional manual operation, improving work efficiency. The first elastic member 9 can automatically adjust the position of the spacer block 7 according to the working state of the grinding tool 3. When the grinding tool 3 slides out, it allows the spacer block 7 to move to a specified position against the elastic force; when the grinding tool 3 retracts, it can make the spacer block 7 automatically reset. The hinged and sliding connection methods of the connecting rod 8 provide transmission between the mounting plate 4 and the spacer block 7. The first elastic member 9, as the reset device of the spacer block 7, its elastic performance ensures that it can accurately reset the spacer block 7 to the initial position after multiple uses, ensuring that each time the grinding tool 3 slides out, the spacer block 7 can reach the position in time to block, avoiding the problem of the grinding tool 3 sliding back caused by inaccurate position of the spacer block 7, and improving the stability and reliability of equipment operation.

[0042] Since the connecting rod 8 and the first elastic member 9 achieve the automatic control of the movement of the cushion block 7, the operator does not need to manually adjust the position of the cushion block 7, which simplifies the operation process. The operator only needs to control the main driving components such as the runner 5 to complete the extension, grinding, retraction of the grinding tool 3 and the corresponding actions of the cushion block 7, reducing the operation difficulty and the errors caused by improper manual operation.

[0043] The structures of the connecting rod 8 and the first elastic member 9 are relatively simple and are easy to disassemble and replace. During the equipment maintenance process, if the connecting rod 8 or the elastic member is damaged, the maintenance personnel can conveniently remove it from the equipment for replacement, reducing the maintenance cost and maintenance time.

[0044] As Figure 1 shown, the sliding frame 10 is slidably arranged on the base frame 1 through a slide rail or a slider, and its sliding on the base frame 1 can be realized by a driving device such as a motor and a lead screw. The mounting shell 2 is rotatably arranged on the sliding frame 10 through a bearing, and a rotation driving member 11 (such as a motor) is mounted on the sliding frame 10 and drives the mounting shell 2 to rotate through a belt drive, a gear drive or the like. One end of the rotating rod 12 is rotatably arranged on the sliding frame 10 through a bearing, and the rotation driving member 11 drives the rotating rod 12 to rotate synchronously with the mounting shell 2. A gear is designed on the rotating shaft of the rotation driving member 11, and a gear is also designed on the rotating rod 12. The two gears are meshed, so that the rotation driving member 11 can drive the rotating rod 12 to rotate. The other end of the rotating rod 12 extends into the mounting shell 2 and drives the runner 5 to rotate through a transmission mechanism such as a gear drive and a chain drive.

[0045] This structural design enables the sliding and rotation of the mounting shell 2 and the rotation of the runner 5 to work together, realizing the multi-action linkage of the mechanism, improving the work efficiency and reducing the cost of the driving member. The slidable design of the sliding frame 10 on the base frame 1 enables the mounting shell 2 and the entire grinding and drilling mechanism to adjust the position within a larger range. The construction personnel can control the position of the sliding frame 10 according to the different positions and shapes of the wall, so that the grinding tool 3 and the subsequent drilling operation can act on the target position. The mounting shell 2 is rotatably arranged on the sliding frame 10 and, in cooperation with the rotation driving member 11, can achieve a ° rotation. This enables the grinding tool 3 to operate from different angles when grinding the wall. During drilling, the drilling angle can also be adjusted according to actual needs to meet diverse construction requirements.

[0046] The rotation driving member 11 drives the mounting shell 2 and the rotating rod 12 to rotate together through gear transmission. At the same time, the rotating rod 12 and the chain transmission mechanism drive the runner 5 to rotate. Since the rotation axes between the rotating rod 12 and the runner 5 are different, the rotating rod 12 can drive the runner 5 to rotate through bevel gears. This transmission method has a compact structure and high transmission efficiency. Both gear transmission and chain transmission have high transmission accuracy, which can ensure the synchronous rotation between components and reduce transmission errors. The coordinated rotation of the mounting shell 2, the rotating rod 12 and the runner 5 enables the grinding tool 3 to work without additional drive.

[0047] As Figure 1 shown, the mounting frame 13 is fixedly arranged on the sliding frame 10. There is a sliding channel for the baffle 14 on the mounting frame 13. The sliding channel can provide guidance for the sliding of the baffle 14. The adjacent baffles 14 are connected by a structure of protrusions and grooves, which not only does not affect the sliding of each baffle 14, but also prevents the dust and soil ground off from flying out of the soil collection space 141. One end of several baffles 14 is slidably arranged on the mounting frame 13 along the sliding direction of the grinding tool 3 through a guide rail or a chute, and the other end is used to abut against the wall. One end of the second elastic member 15 (such as a spring) is fixed on the mounting frame 13, and the other end is fixed on the other end of the baffle 14, providing an outward elastic pushing force for the baffle 14 to make the baffle 14 closely abut against the wall. Several baffles 14 together enclose the soil collection space 141, and the mounting shell 2 is located in this space. The design of the baffle 14 can adapt to the uneven wall surface.

[0048] The setting of the soil collection space 141 can collect the dust and soil generated during the grinding process and reduce the pollution of the working environment. The close abutment of the baffle 14 against the wall can further fix the mechanism and improve the stability of grinding and drilling.

[0049] As Figure 1As shown in the figure, the gripper 16 is installed on the base frame 1, and the drill pipe is clamped by mechanical jaws, hydraulic chucks or other means. The drilling rig 17 is slidably arranged on the base frame 1 through a slide rail. Its rotating part (such as a screw driven by a motor) has a threaded hole, and the threaded section of the drill pipe is threadedly engaged with the threaded hole. When the rotating part rotates, it drives the drill pipe to slide and rotate on the base frame 1, so that the drill pipe is driven into the wall. The drilling rig 17 is composed of a propulsion mechanism and a rotation mechanism. The propulsion mechanism drives the drill pipe to slide, so that the drill pipe approaches the wall or is driven into the wall. The rotation mechanism drives the drill pipe to rotate. The rotation mechanism and the gripper 16 cooperate to realize the connection of multiple drill pipes. The rotation mechanism 172 and the propulsion mechanism 171 cooperate to enable the drill pipe to drill holes in the wall better. The gripper 16 is composed of a front gripper and a rear gripper. The front gripper and the rear gripper cooperate to realize the loading and unloading of the drill pipe. The gripper 16 and the drilling rig 17 cooperate with each other to realize the drilling function, which is highly integrated and can realize one-key automatic drilling. The base frame 1 also has a second tightening member. The second tightening member and the sliding frame slide in the opposite direction. One presses forward against the inner wall of the roadway, and the other can press backward against the inner wall of the roadway to enhance the stability of drilling.

[0050] This transmission method of threaded engagement can control the driving depth and speed of the drill pipe, and can also realize the lengthening connection of multiple drill pipes. The drill pipe library 18 is rotatably arranged on the base frame 1 through bearings and can be driven to rotate by a motor, which is convenient for the manipulator 19 to grab drill pipes at different positions. The installation part of the manipulator 19 is fixed on the base frame 1, and the grabbing part adopts structures such as mechanical jaws. Through driving devices such as motors and cylinders, it realizes the grabbing and moving of the drill pipe, and moves the drill pipe from the drill pipe library 18 to between the drilling rig 17 and the gripper 16.

[0051] The setting of the drill pipe library 18 and the manipulator 19 realizes the automatic replacement of the drill pipe, reduces manual operation, improves work efficiency, and enables the electric drilling mechanism to continuously and efficiently carry out drilling operations.
