[0014] Compared with the prior art, the present invention provides a safe and reliable anti-vibration rock drill, which has the following beneficial effects: This safe and reliable anti-vibration rock drilling mechanism, through its lowered center of gravity design, can more effectively resist the instability caused by vibration when subjected to vibration. When this safe and reliable anti-vibration rock drilling mechanism is working, the mechanism itself will generate strong vibrations. Lowering the center of gravity can reduce the interference of vibration on the overall stability of the equipment, keeping the equipment in a relatively fixed position.

[0015] 2. This safe and reliable anti-vibration rock drilling mechanism effectively reduces the vibration amplitude of the device during operation, thereby reducing excessive rock fragmentation caused by severe vibration and controlling the range of fragments flying.

[0016] 3. This safe and reliable anti-vibration rock drilling mechanism can effectively isolate and absorb the impact and vibration generated during the operation of the device, effectively reducing the vibration transmitted to the rectangular hollow shell and T-shaped threaded handle.

[0017] 4. This safe and reliable anti-vibration rock drilling mechanism effectively absorbs and buffers the impact and vibration energy generated during operation through the internal shock-absorbing and fixing device. When the drill rod is subjected to uneven rock forces, it can quickly absorb and buffer the forces that cause radial displacement of the drill rod, keeping the drill rod in a relatively stable position, reducing radial vibrations such as left and right swaying, improving working stability and rock drilling accuracy.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Example 1, please refer to Figures 1-7 This invention provides a technical solution: a safe and reliable anti-vibration rock drill, including a T-shaped threaded grip 1. The T-shaped threaded grip 1 is detachable and, through its ergonomic design, perfectly conforms to the curves of the operator's palm and fingers, reducing gaps and pressure points between the operator's hand and the grip. This makes the operator feel more comfortable and natural, and allows for more natural and relaxed application of force when holding the drill, reducing extra muscle strain and allowing force to be transmitted more smoothly to the rock drill, thereby reducing vibration during long periods of use. To reduce fatigue in the hands, arms, and shoulders caused by intermittent operation, a rotating stop device 2 is fixedly connected to the surface of the T-shaped threaded grip 1. The rotating stop device 2 is used to prevent the T-shaped threaded grip 1 from loosening due to vibration without affecting the disassembly of the T-shaped threaded grip 1. The rotating stop device 2 is located on the surface of the vertical part of the T-shaped threaded grip 1. When the axis of the rotating stop device 2 is perpendicular to the axis of the cylindrical outer shell 301, the T-shaped threaded grip 1 will be blocked by the first limit plate 302 when rotating. An anti-vibration rock drilling mechanism 3 is threadedly connected to the bottom of the surface of the T-shaped threaded grip 1. The anti-vibration rock drilling mechanism 3 includes a cylindrical outer shell 301 with a rectangular groove inside. A first limiting plate 302 and a second limiting plate 303 are fixedly connected to the top of the cylindrical outer shell 301. The second limiting plate 303 is located above the protective center of gravity device 304. The protective center of gravity device 304 effectively improves the stability and operability of the anti-vibration rock drilling mechanism 3 by lowering its center of gravity. When the center of gravity is lowered, the anti-vibration rock drilling mechanism 3 is less likely to tip over or shake during operation, especially in complex terrain or high-intensity operations. This not only reduces operator fatigue but also improves operational accuracy and efficiency. In addition, lowering the center of gravity can reduce equipment vibration, extend service life, and reduce maintenance costs, thus improving the overall performance and reliability of the anti-vibration rock drilling mechanism 3. At the same time, it blocks the gravel and dust generated during the operation of the anti-vibration rock drilling mechanism 3, preventing them from endangering the operator. The system ensures personnel safety and reduces noise from the rock drill rod 307 impacting the rock during operation. A protective center-of-gravity device 304 is fixedly connected to the cylindrical surface of the cylindrical shell 301. Two first damping springs 305 are fixedly connected inside the cylindrical shell 301. A first power device 306 is fixedly connected to the bottom of each first damping spring 305. A rectangular clamping plate is fixedly connected to the surface of the first power device 306. The rectangular clamping plate works in conjunction with the rectangular groove inside the cylindrical shell 301 to restrict the radial freedom of the first power device 306. A rock drill rod 307 is fixedly connected inside the first power device 306. A vibration damping fixing device 308 is fixedly connected inside the first power device 306. The vibration damping fixing device 308 reduces vibration and shortens the exposed length of the rock drill rod 307, reducing the vibration amplitude of the short rock drill rod 307.

[0025] When the operator needs to use the device, rotate the anti-vibration rock drilling mechanism 3 to align the second limiting plate 303 with the opening of the annular groove 402. Then, rotate the stop bar of the rotating stop bar device 2 to align the axis of the stop bar of the rotating stop bar device 2 with the axis of the cylindrical housing 301. Then, rotate the T-shaped threaded handle 1 to remove the T-shaped threaded handle 1 from the anti-vibration rock drilling mechanism 3. Then, detach the anti-vibration rock drilling mechanism 3 from the moving fixing device 4. Then, rotate the T-shaped threaded handle 1 to install the T-shaped threaded handle 1 on top of the anti-vibration rock drilling mechanism 3. Finally, rotate the stop bar of the rotating stop bar device 2 to align the stop bar of the rotating stop bar device 2 with the opening of the annular groove 402. The rod axis is perpendicular to the axis of the cylindrical shell 301. The operator holds the T-shaped threaded handle 1 to work, and then the first power device 306 drives the rock drill rod 307 to reciprocate to impact the rock. During this process, vibration is generated. When the vibration is transmitted to the first damping spring 305 located between the cylindrical shell 301 and the first power device 306, the first damping spring 305 can convert the vibration energy into its own elastic potential energy, and gradually dissipate this energy through reciprocating motion, thereby effectively isolating the transmission of vibration to the rectangular hollow shell 401 and the T-shaped threaded handle 1.

[0026] The protective center of gravity device 304 includes a first annular pressure block 3041. An annular groove 3042 is formed inside the first annular pressure block 3041. The size of the annular groove 3042 is the same as that of the annular baffle 3043. The annular baffle 3043 is slidably connected inside the annular groove 3042. A rubber plate is fixedly connected inside the first annular pressure block 3041 and the annular baffle 3043. The rubber plate is used to prevent flying rock fragments from the anti-vibration rock drilling mechanism 3 from directly impacting the inner walls of the first annular pressure block 3041 and the annular baffle 3043 during operation, thereby reducing noise pollution. A second annular... The inner ring size of the second annular pressure block 3044 is the same as that of the inner ring size of the annular baffle 3043. The outer ring size of the second annular pressure block 3044 is larger than that of the annular baffle 3043. The outer ring size of the second annular pressure block 3044 is the same as that of the first annular pressure block 3041. An annular rubber buffer block 3045 is fixedly connected to the surface of the second annular pressure block 3044. The annular rubber buffer block 3045 is used to prevent the second annular pressure block 3044 from directly hitting the ground, protect the second annular pressure block 3044, and reduce the noise pollution caused by the impact of the second annular pressure block 3044 on the ground.

[0027] Before vibration occurs, the center of gravity of the anti-vibration rock drilling mechanism 3 is lowered by the protective center of gravity device 304, making it less likely to sway or tilt when subjected to external impact or vibration. When the center of gravity is lower, the inertial torque of the anti-vibration rock drilling mechanism 3 is reduced, and the vibration energy is more evenly distributed throughout the structure, thereby effectively suppressing the transmission and amplification of vibration, thus reducing the vibration generated during the operation of the anti-vibration rock drilling mechanism 3. In this process, the annular baffle 3043 slides down under the action of gravity, causing the annular rubber buffer block 3045 to contact the ground, blocking the flying debris, dust and noise generated when the rock drill rod 307 hits the rock in the enclosed space, avoiding injury to the operator from the flying debris, dust and noise.

[0028] The shock-absorbing fixing device 308 includes an inverted T-shaped fixing rod 3081. The diameter of the base of the inverted T-shaped fixing rod 3081 is the same as the diameter of the top cover of the T-shaped slide rod 3083. A first sliding groove 3082 is fixedly connected inside the inverted T-shaped fixing rod 3081. The diameter of the first sliding groove 3082 is the same as the diameter of the vertical part of the T-shaped slide rod 3083. The T-shaped slide rod 3083 is fixedly connected inside the first sliding groove 3082. A second compression spring 3084 is fixedly connected to the bottom of the top cover of the T-shaped slide rod 3083. The other end of the second compression spring 3084 is connected to the inverted T-shaped fixing rod 3083. The base of rod 3081 is fixedly connected. The maximum outer diameter of the second compression spring 3084 is smaller than the diameter of the base of the inverted T-shaped fixed rod 3081, and the minimum inner diameter of the second compression spring 3084 is larger than the diameter of the vertical part of the inverted T-shaped fixed rod 3081. The cylindrical surface of the anti-vibration rock drilling mechanism 3 is clamped with a movable fixing device 4. There are three shock-absorbing fixing devices 308, which are evenly distributed on the top of the fixing plate 309 along the axis of the rock drilling rod 307. The bottom of the shock-absorbing fixing device 308 is fixedly connected to the fixing plate 309, and the fixing plate 309 is fixedly connected to the surface of the rock drilling rod 307.

[0029] When the vibration is transmitted to the damping and fixing device 308, the vibration energy is converted into its own elastic potential energy by the second compression spring 3084, and this energy is gradually dissipated through reciprocating motion. Then, the rock drill rod 307 that is reciprocating motion is stabilized by the inverted T-shaped fixing rod 3081 and the T-shaped sliding rod 3083, reducing the radial vibration of the rock drill rod 307 during the movement.

[0030] Example 2, based on Example 1, please refer to... Figure 8This invention provides a technical solution: the mobile fixing device 4 includes a rectangular hollow shell 401, which is used to fix the anti-vibration rock drilling mechanism 3. Simultaneously, without affecting the support and fixing effect, the hollow design reduces its weight, thereby reducing production costs. An annular groove 402 is provided at the top of the rectangular hollow shell 401, and a second limiting plate 303 is used to restrict the axial freedom of the anti-vibration rock drilling mechanism 3. The second limiting plate 303 is located inside the annular groove 402. A rectangular pressure block 403 is fixedly connected to the bottom of the rectangular hollow shell 401. The rectangular pressure block 403 is used to lower the center of gravity of the device, improve its stability, and replace the pressure applied by the operator to the anti-vibration rock drilling mechanism 3 during operation. Two rectangular pressure blocks 403 are used. The rectangular pressure blocks 403 are symmetrically arranged along the axis of the cylindrical outer shell 301, and are located on two parallel sides of the rectangular hollow outer shell 401. There are two support blocks 404, which are also symmetrically arranged along the axis of the cylindrical outer shell 301. The support blocks 404 are located on two parallel sides of the rectangular hollow outer shell 401, and the sides of the rectangular pressure blocks 403 and support blocks 404 are perpendicular to each other. The bottom of the rectangular hollow outer shell 401 is fixedly connected to the support blocks 404, and the bottom of the support blocks 404 is rotatably connected to the track moving device 405. The track moving device 405 is used to drive the device to move, and the anti-slip texture on the outer surface of the track enhances the grip of the track, effectively preventing the track from slipping on wet or soft ground, and improving the stability of the device during operation.

[0031] When the device is not required to be used by an operator, the second limiting plate 303 is aligned with the opening of the annular groove 402, and the anti-vibration rock drilling mechanism 3 is rotated to fix the second limiting plate 303 inside the annular groove 402. The anti-vibration rock drilling mechanism 3 is then fixed on the moving fixing device 4. The stop bar of the rotating stop bar device 2 is then rotated to make the axis of the stop bar of the rotating stop bar device 2 perpendicular to the axis of the cylindrical housing 301. The T-shaped threaded handle 1 is then rotated to install the T-shaped threaded handle 1 on the top of the anti-vibration rock drilling mechanism 3. The anti-vibration rock drilling mechanism 3 is then moved by the track moving device 405. The rectangular pressure block 403 applies pressure to the anti-vibration rock drilling mechanism 3 to replace the fixing role played by the operator during the operation of the anti-vibration rock drilling mechanism 3. The machine then replaces the manual operation to repeat the above operation.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
