DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

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

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] For example, see Figure 1-Figure 7 The present invention provides a technical solution: a safe and reliable anti-shake rock drill, comprising a T-shaped threaded handle 1. The T-shaped threaded handle 1 is detachable and has an ergonomic design on its surface, so that the handle can perfectly fit the curve of the operator's palm and fingers, reduce the gap and pressure point between the operator's hand and the handle, make the operator feel more comfortable and natural, and enable the operator to apply force in a more natural and relaxed way when holding, reduce the extra burden on the muscles, and allow the force to be more smoothly transmitted to the rock drill, thereby reducing the long-term The T-thread grip 1 is fixedly connected with a rotating stopper 2 on its surface to prevent the T-thread grip 1 from loosening due to vibration without affecting the disassembly of the T-thread grip 1. The rotating stopper 2 is located on the surface of the vertical part of the T-thread grip 1. When the axis of the stopper of the rotating stopper 2 is perpendicular to the axis of the cylindrical housing 301, the T-thread grip 1 will be blocked by the first limit plate 302 when rotating. The bottom of the surface of the T-thread grip 1 is threadedly connected with an anti-shake rock drilling mechanism 3. The anti-shake rock drilling mechanism 3 includes a cylindrical shell 301, a rectangular slide groove is opened inside the cylindrical shell 301, a first limit plate 302 is fixedly connected to the top of the cylindrical shell 301, and a second limit plate 303 is fixedly connected to the top of the cylindrical shell 301. The second limit plate 303 is located above the protective center of gravity device 304. The protective center of gravity device 304 is used to effectively improve the stability and controllability of the anti-shake rock drilling mechanism 3 by lowering the center of gravity of the anti-shake rock drilling mechanism 3. When the center of gravity is lowered, the anti-shake 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 the fatigue of the operator, but also improves the operation accuracy and efficiency. In addition, lowering the center of gravity can also reduce equipment vibration, extend service life, and reduce maintenance costs. The performance and reliability of the anti-shake rock drilling mechanism 3 are improved as a whole. At the same time, the gravel and dust generated during the operation of the anti-shake rock drilling mechanism 3 are blocked to prevent the gravel and dust from endangering the operation The body safety of personnel and the noise of the rock drilling rod 307 hitting the rock during the operation of the anti-shake rock drilling mechanism 3 are weakened to a certain extent. The cylindrical surface of the cylindrical shell 301 is fixedly connected with a protective center of gravity device 304, and the cylindrical shell 301 is fixedly connected with a first shock-absorbing spring 305. The number of the first shock-absorbing springs 305 is two, and the bottom of the first shock-absorbing spring 305 is fixedly connected with a first power device 306. The surface of the first power device 306 is fixedly connected with a rectangular card plate. The surface of the first power device 306 is fixedly connected with a rectangular card plate. The rectangular card plate is used to cooperate with the rectangular slide groove opened in the cylindrical shell 301 to limit the radial freedom of the first power device 306. The first power device 306 is fixedly connected with a rock drilling rod 307. The first power device 306 is fixedly connected with a shock-absorbing fixture 308. The shock-absorbing fixture 308 is used to reduce vibration, shorten the exposed length of the rock drilling rod 307, and reduce the vibration amplitude of the short rock drilling rod 307.

[0025] When the operator needs to use the device, the anti-shake rock drilling mechanism 3 is rotated to align the second limit plate 303 with the opening of the annular groove 402, and then the stop rod of the rotating stop rod device 2 is rotated to make the stop rod axis of the rotating stop rod device 2 parallel to the axis of the cylindrical shell 301, and then the T-shaped threaded handle 1 is rotated to remove the T-shaped threaded handle 1 from the anti-shake rock drilling mechanism 3, and then the anti-shake rock drilling mechanism 3 is separated from the mobile fixing device 4, and then the T-shaped threaded handle 1 is rotated to install the T-shaped threaded handle 1 on the top of the anti-shake rock drilling mechanism 3, and then the stop rod of the rotating stop rod device 2 is rotated to make the stop rod of the rotating stop rod device 2 parallel to the axis of the cylindrical shell 301. 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 drives the rock drill rod 307 to reciprocate and hit the rock through the first power device 306. Vibration is generated in this process. When the vibration is transmitted to the first shock-absorbing spring 305 located between the cylindrical shell 301 and the first power device 306, the first shock-absorbing spring 305 can convert the vibration energy into its own elastic potential energy, and gradually dissipate the 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 center of gravity protection device 304 includes a first annular pressure block 3041, an annular slide groove 3042 is provided inside the first annular pressure block 3041, the size of the annular slide groove 3042 is consistent with the annular baffle 3043, the annular slide groove 3042 is slidably connected to the annular baffle 3043, the first annular pressure block 3041 and the annular baffle 3043 are fixedly connected with a rubber plate, the rubber plate is used to prevent the splashing gravel during the operation of the anti-shake rock drilling mechanism 3 from directly hitting the inner wall of the first annular pressure block 3041 and the annular baffle 3043, so as to reduce the generation of noise pollution, and the bottom of the annular baffle 3043 is fixedly connected with a second annular The pressure block 3044 has an inner ring size that is consistent with the inner ring size of the circular baffle 3043, an outer ring size of the second circular pressure block 3044 is larger than the outer ring size of the circular baffle 3043, and an outer ring size of the second circular pressure block 3044 is consistent with the outer ring size of the first circular pressure block 3041. A circular rubber buffer block 3045 is fixedly connected to the surface of the second circular pressure block 3044. The circular rubber buffer block 3045 is used to prevent the second circular pressure block 3044 from directly hitting the ground, protect the second circular pressure block 3044, and reduce the noise pollution caused by the second circular pressure block 3044 hitting the ground.

[0027] Before vibration occurs, the center of gravity of the anti-shake rock drilling mechanism 3 is lowered by the center of gravity protection device 304, so that the anti-shake rock drilling mechanism 3 is not easy to shake or tilt when subjected to external impact or vibration, and when the center of gravity is low, the inertia moment of the anti-shake rock drilling mechanism 3 is reduced, and the vibration energy is more evenly distributed in the entire structure, thereby effectively suppressing the transmission and amplification of vibration, thereby reducing the vibration generated during the operation of the anti-shake rock drilling mechanism 3, and in this process, the annular baffle 3043 slides downward under the action of gravity, so that the annular rubber buffer block 3045 contacts the ground to block the splashing gravel, dust and noise generated when the rock drilling rod 307 hits the rock in a closed space, thereby preventing the splashing gravel, dust and noise from causing harm to the operator.

[0028] The shock absorbing fixing device 308 includes an inverted T-shaped fixing rod 3081, the base diameter of the inverted T-shaped fixing rod 3081 is consistent with the top cover diameter of the T-shaped sliding rod 3083, the inverted T-shaped fixing rod 3081 is fixedly connected with a first slide groove 3082, the diameter of the first slide groove 3082 is consistent with the vertical portion diameter of the T-shaped sliding rod 3083, the first slide groove 3082 is fixedly connected with the T-shaped sliding rod 3083, the top cover bottom of the T-shaped sliding rod 3083 is fixedly connected with a second compression spring 3084, the other end of the second compression spring 3084 is fixedly connected with the inverted T-shaped fixing rod 3081, and the second compression spring 3084 is fixedly connected with the inverted T-shaped fixing rod 3081. The base of the rod 3081 is fixedly connected, the maximum outer diameter of the second compression spring 3084 is smaller than the base diameter of the inverted T-shaped fixing rod 3081, the minimum inner diameter of the second compression spring 3084 is larger than the vertical part diameter of the inverted T-shaped fixing rod 3081, the anti-shake rock drilling mechanism 3 is clamped with a movable fixing device 4 on the cylindrical surface, the number of shock-absorbing fixing devices 308 is three, and they 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 with a 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 shock-absorbing fixing device 308, the vibration energy is converted into its own elastic potential energy through the second compression spring 3084, and the energy is gradually dissipated through reciprocating motion. Then, the reciprocating rock drilling rod 307 is stabilized by the inverted T-shaped fixing rod 3081 and the T-shaped sliding rod 3083, thereby reducing the radial jitter of the rock drilling rod 307 during the movement.

[0030] Example 2, based on Example 1, please refer to Figure 8The present invention provides a technical solution: the mobile fixing device 4 includes a rectangular hollow shell 401, and the rectangular hollow shell 401 is used to fix the anti-shake rock drilling mechanism 3. At the same time, without affecting the support and fixing effects, the hollow design is used to reduce its mass, thereby reducing the production cost. An annular groove 402 is opened on the top of the rectangular hollow shell 401, and the second limit plate 303 is used to limit the axial freedom of the anti-shake rock drilling mechanism 3. The second limit plate 303 is located inside the annular groove 402. A rectangular pressing block 403 is fixedly connected to the bottom of the rectangular hollow shell 401. The rectangular pressing block 403 is used to lower the center of gravity of the device to improve its stability, and replace the pressure applied by the operator to the anti-shake rock drilling mechanism 3 during operation. There are two rectangular pressing blocks 403, and The cylindrical shell 301 is symmetrical with each other along the axis, and the rectangular pressure blocks 403 are respectively located on two parallel sides of the rectangular hollow shell 401. There are two support blocks 404, which are symmetrical with each other along the axis of the cylindrical shell 301. The support blocks 404 are respectively located on two parallel sides of the rectangular hollow shell 401. The rectangular pressure blocks 403 and the side lines of the support blocks 404 are perpendicular to each other. The bottom of the rectangular hollow shell 401 is fixedly connected to the support block 404, and the bottom of the support block 404 is rotatably connected to a 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, thereby improving the stability of the device during operation.

[0031] When the operator is not required to use the device, the second limit plate 303 is aligned with the opening of the annular groove 402 and then the anti-shake rock drilling mechanism 3 is rotated to fix the second limit plate 303 inside the annular groove 402, and the anti-shake rock drilling mechanism 3 is fixed on the movable fixing device 4. Then the baffle rod of the rotating baffle rod device 2 is rotated to make the baffle rod axis of the rotating baffle rod device 2 perpendicular to the axis of the cylindrical shell 301. Then the T-shaped threaded handle 1 is rotated and installed on the top of the anti-shake rock drilling mechanism 3. Then the anti-shake rock drilling mechanism 3 is driven to move by the crawler moving device 405. Then, pressure is applied to the anti-shake rock drilling mechanism 3 by the rectangular pressure block 403 to replace the fixing role played by the operator during the operation of the anti-shake rock drilling mechanism 3. Then, the above operation is repeated mechanically instead of manually.
