Abstract
Description
Technical Field
[0001] This utility model relates to the field of mine rescue technology, specifically a demolition tool for mine rescue. Background Technology
[0002] Gas explosions, water inrushes, fires, coal dust explosions, and roof collapses are common accidents in coal mining, posing a huge threat to the lives of miners and the safety of the mine. When a safety accident occurs in a mine, in order to minimize casualties, refuge chambers or fixed underground rescue capsules are now often set up in mines to await rescue. During the rescue process, it is necessary to break down the mine, so demolition tools are required.
[0003] The demolition targets in mine rescue are mainly hard materials such as collapsed concrete structures, deformed steel supports, and rock fragments blocking passages. Electric impact drills, through a combined rotation and impact motion mode, can quickly drill, break, or enlarge holes in hard materials, creating conditions for subsequent rescue operations such as support, cutting, and expansion.
[0004] In existing electric impact drills, the drill bit is always exposed, whether in use or not. This exposed drill bit is prone to collisions and scrapes with other tools during transport, leading to chipping, deformation of the drill bit's cutting edge, or bending of the drill rod. Furthermore, dust, moisture, and acidic or alkaline corrosive media in the mining environment can directly adhere to the drill bit, causing rust and corrosion, reducing its hardness and sharpness. To address this problem, we have proposed a demolition tool for mine rescue. Utility Model Content
[0005] The purpose of this utility model is to provide a demolition tool for mine rescue, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a demolition tool for mine rescue, comprising an electric impact drill, wherein the electric impact drill penetrates a cylinder and is fixedly connected to the cylinder, a drill bit is provided on the side of the electric impact drill, and a control component and a driven component are provided on the cylinder, wherein the control component includes: A fixing rod is provided on the outer wall of a cylinder, and the outer wall of the cylinder is provided with a horizontal groove and a slot. The sleeve has a protrusion on its inner wall. When the protrusion is located in the slot, it can restrict the lateral movement of the sleeve, thereby preventing the drill bit from colliding or scraping with other tools during transportation and preventing the sleeve from interfering with the normal operation of the drill bit during the use of the electric impact drill.
[0007] Preferably, the fixing rod is welded to the outer wall of the cylinder, and a transverse groove is provided at the top of the cylinder. When the sleeve moves laterally, the protrusion can move laterally within the transverse groove.
[0008] Preferably, the outer wall of the cylinder is provided with a groove, and the outer wall of the cylinder fits against the inner wall of the sleeve. When the protrusion is located in the groove and no longer in contact with the transverse groove, the lateral movement of the sleeve can be restricted.
[0009] Preferably, the inner wall of the sleeve is welded with a protrusion, the bottom of which is arc-shaped, so that the protrusion can move laterally within the transverse groove when the sleeve moves laterally.
[0010] Preferably, the driven component includes a ring, and a round rod is welded to the side of the ring. The round rod passes through the sleeve and is slidably connected to the sleeve. When the ring is abutted, the round rod can move laterally within the sleeve.
[0011] Preferably, the left side of the ring is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the side of the sleeve. When the ring is no longer subjected to the squeezing force, it can spring up from the side of the sleeve under the action of the spring.
[0012] Preferably, the right side of the ring is rotatably connected to the support block, the support block has a single-sided bevel, and a rotating rod is fixedly installed on the side of the support block. The rotating rod passes through the ring and is rotatably connected to the ring. When the bevel of the support block is abutted, the ring will be simultaneously subjected to a squeezing force and will move laterally.
[0013] Compared with the prior art, this utility model provides a demolition tool for mine rescue, which has the following beneficial effects: 1. This mine rescue demolition tool is equipped with a control component. A rotating sleeve on the outer wall of the cylinder causes a protrusion fixed to the inner wall of the sleeve to move in a circular motion within a groove. When the protrusion rotates to the interface between the transverse groove and the groove, the sleeve moves laterally within the cylinder. The protrusion fixed to the inner wall of the sleeve moves along the transverse groove and in the direction of the drill bit, protecting the drill bit. When the drill bit is needed, simply move the sleeve to move the protrusion into the groove and rotate the sleeve to lock the sleeve, preventing the protrusion from contacting the transverse groove. This prevents the drill bit from colliding or scraping with other tools during transport and avoids the sleeve interfering with the normal operation of the drill bit during the use of an electric impact drill.
[0014] 2. This mine rescue demolition tool is equipped with a driven component. When the sleeve and protrusion rotate inside the cylinder, the fixed rod will abut against the inclined surface of the support block. When the inclined surface of the support block is abutted, the ring can drive the rod to move laterally inside the sleeve. When the sleeve needs to be reversed, the side of the support block will be restricted by the fixed rod, preventing the sleeve from rotating. This achieves the purpose of locking the sleeve a second time, preventing the sleeve from slipping and colliding with the drill bit during drill bit use and causing damage.

[0017] like Figures 1-6As shown, this utility model provides a technical solution: a demolition tool for mine rescue, including an electric impact drill 1, which penetrates a cylinder 3 and is fixedly connected to the cylinder 3. A drill bit 2 is provided on the side of the electric impact drill 1. A control component 4 and a driven component 5 are provided on the cylinder 3. The control component 4 includes: a fixed rod 41, a transverse groove 42, a slot 43, a sleeve 44, and a protrusion 45. The fixed rod 41 is located on the outer wall of the cylinder 3. The outer wall of the cylinder 3 is provided with the transverse groove 42 and the slot 43. The inner wall of the sleeve 44 is provided with the protrusion 45. When the protrusion 45 is located within the slot 43, it can restrict the lateral movement of the sleeve 44. When the sleeve 44 rotates on the outer wall of the cylinder 3, the inner wall of the sleeve 44 is fixed... The protrusion 45 rotates in the groove 43. When the protrusion 45 rotates to the interface between the transverse groove 42 and the groove 43, the sleeve 44 moves laterally within the cylinder 3. The protrusion 45 fixed to the inner wall of the sleeve 44 moves along the transverse groove 42 and along the direction of the drill bit 2 to protect the drill bit 2. When the drill bit 2 needs to be used, simply move the sleeve 44 to move the protrusion 45 into the groove 43 and rotate the sleeve 44 so that the protrusion 45 no longer contacts the transverse groove 42 to lock the sleeve 44. This prevents the drill bit 2 from colliding or scraping with other tools during transportation and avoids the sleeve 44 interfering with the normal operation of the drill bit 2 during the use of the electric impact drill 1.
[0018] A fixing rod 41 is welded to the outer wall of the cylinder 3. A transverse groove 42 is provided at the top of the cylinder 3. When the sleeve 44 moves laterally, the protrusion 45 can move laterally within the transverse groove 42. A slot 43 is provided on the outer wall of the cylinder 3. The outer wall of the cylinder 3 fits against the inner wall of the sleeve 44. When the protrusion 45 is located in the slot 43 and is no longer in contact with the transverse groove 42, the lateral movement of the sleeve 44 can be restricted. A protrusion 45 is welded to the inner wall of the sleeve 44. The bottom of the protrusion 45 is arc-shaped. When the sleeve 44 moves laterally, the protrusion 45 can move laterally within the transverse groove 42. The driven component 5 includes a ring 51. A round rod 52 is welded to the side of the ring 51. The round rod 52 passes through the sleeve 44 and is slidably connected to the sleeve 44. When the ring 51 is abutted, the round rod 52 can move laterally within the sleeve 44. The left side of the ring 51 is fixedly connected to one end of the spring 53, and the other end of the spring 53 is fixedly installed on the side of the sleeve 44. When the ring 51 is no longer subjected to compressive force, it can spring up from the side of the sleeve 44 under the action of the spring 53. The right side of the ring 51 is rotatably connected to the support block 54. The support block 54 has a single-sided beveled surface. A rotating rod 55 is fixedly installed on the side of the support block 54. The rotating rod 55 passes through the ring 51 and is rotatably connected to the ring 51. When the beveled surface of the support block 54 is abutted, the ring 51 will be simultaneously subjected to compressive force and move laterally.
[0019] In this invention, when the electric impact drill 1 is needed for mine rescue, the sleeve 44 is pushed at the top of the cylinder 3. The protrusion 45 fixed to the inner wall of the sleeve 44 slides along the transverse groove 42. When the protrusion 45 moves within the transverse groove 42, the sleeve 44 no longer obstructs the drill bit 2. When the protrusion 45 moves to the interface between the transverse groove 42 and the slot 43, the sleeve 44 is rotated clockwise, and the protrusion 45 fixed to the inner wall of the sleeve 44 will slide along the transverse groove 42. The ring 52 slides within the slot 43 and no longer contacts the transverse groove 42. During the rotation of the sleeve 44, the fixing rod 41 will abut against the chamfered surface of the support block 54. When the chamfered surface of the support block 54 is abutted, the ring 51 can drive the round rod 52 to move laterally within the sleeve 44. When the sleeve 44 needs to be reversed, the side of the support block 54 will be restricted by the fixing rod 41, preventing the sleeve 44 from rotating, thereby achieving the purpose of locking the sleeve 44 a second time. To prevent the sleeve 44 from slipping and colliding with the drill bit 2 during use, thus avoiding damage, the drill bit 2 can be used for dismantling. When the drill bit 2 is no longer needed, the rotating rod 55 is turned on the side of the ring 51. The rotating rod 55 drives the support block 54 to rotate. After the support block 54 rotates half a turn, the fixing rod 41 can contact the beveled surface of the support block 54, so it will not affect its normal reversal. Then, the sleeve 44 is rotated on the surface of the cylinder 3. The protrusion 45 fixed on the inner wall of the sleeve 44 slides in the groove 43. When the protrusion 45 moves to the interface between the groove 43 and the transverse groove 42, the sleeve 44 is moved laterally. The protrusion 45 fixed on the inner wall of the sleeve 44 slides along the transverse groove 42 and protects the drill bit 2. This prevents the drill bit 2 from colliding or scratching with other tools during transportation and prevents the sleeve 44 from interfering with the normal operation of the drill bit 2 during the use of the electric impact drill 1.
[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
