Description

Technical Field

[0001] This invention relates to the field of building construction, and more specifically, to a blasting drilling device for blasting operations. Background Technology

[0002] Blasting drilling equipment is a common type of energy-saving mining machinery. As the core pre-operational equipment in mining blasting operations, its core responsibility is to efficiently, accurately, and with low consumption drill blast holes that meet design standards in hard working faces such as rocks and ore bodies before mining blasting operations, providing a basic guarantee for subsequent explosive loading, safe detonation, and rock breaking.

[0003] For example, the Chinese invention patent (application number: CN202211134057.1) discloses a "blasting drilling device for blasting construction". The specification states that when the drill bit is aligned with the blasting surface to be drilled, the rollers at the ends of multiple support rods will first contact the working surface. As the drill bit approaches the working surface, the support rods are squeezed and spread outward, thereby increasing their contact area with the working surface and making the drill bit more stable during the drilling process. The driving component drives the limiting component to rotate between the roller and the plane to be drilled to limit the roller, which can prevent slippage during the drilling stage when the drill bit contacts the working surface.

[0004] However, the aforementioned blasting drilling device for blasting construction has some shortcomings in actual use: In the existing technology, the drill bit anti-slip is achieved by expanding the support rod and limiting the roller. However, in actual use, the support rod and roller can only be used in flat and regular rock layers. For rock masses with complex geological conditions and uneven rock surfaces, the support rod cannot be extended, making it impossible for the device to perform anti-slip work. The device cannot adapt to the mine terrain, resulting in poor applicability.

[0005] Therefore, we have made improvements to this and proposed a blasting drilling device for blasting construction. Summary of the Invention

[0006] The purpose of this invention is to address the problem that existing blasting drilling devices used in blasting operations cannot prevent the drill bit from slipping when drilling into uneven mine rock masses, resulting in low equipment applicability.

[0007] To achieve the above-mentioned objectives, the present invention provides a blasting drilling device for blasting operations to solve the aforementioned problems.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: 1. In order to solve the problem that existing blasting drilling devices used in blasting construction cannot prevent the drill bit from slipping when drilling into uneven mine rock masses, resulting in low equipment applicability, this application improves the applicability of the device by setting a synchronous adjustment mechanism. The synchronous adjustment mechanism drives the wedge part to adaptively fit the working surface, so that the device can perform anti-slip treatment on uneven working surfaces. 2. By setting a synchronous adjustment mechanism, the inclined part is driven to vibrate, and the vibration roughens the working surface, which improves the roughness of the working surface.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] As described in the background section, when drilling into uneven rock masses in mines, the blasting drilling device used in blasting operations cannot prevent the drill bit from slipping, resulting in low applicability of the equipment.

[0022] To solve this technical problem, the present invention provides a blasting drilling device for blasting construction, which is applied to building construction.

[0023] For details, please refer to Figure 1 - Figure 9 As shown, the blasting drilling device for blasting construction specifically includes: a body 1, a drill bit 101 rotatably mounted on the body 1, and a synchronous adjustment mechanism 2 mounted on the body 1; The synchronous adjustment mechanism 2 includes a sliding groove 201 disposed on the body 1, a support block 202 slidably disposed on the sliding groove 201, a drive ring 203 slidably disposed on the sliding groove 201, a spring 204 disposed on the corresponding surfaces of the support block 202 and the drive ring 203, an electric telescopic rod 205 disposed on the body 1, and an inclined portion 206 disposed on the support block 202.

[0024] The blasting drilling device for blasting construction provided by this invention addresses the problem that existing blasting drilling devices for blasting construction cannot prevent the drill bit 101 from slipping when drilling into uneven mine rock masses, resulting in low equipment applicability. This application improves the applicability of the device by setting a synchronous adjustment mechanism 2, which drives the wedge-shaped part to adaptively fit the working surface, thereby preventing slippage on uneven working surfaces. The synchronous adjustment mechanism 2 drives the inclined part 206 to vibrate, and the vibration roughens the working surface, improving the roughness of the working surface. This allows the inclined part 206 to automatically fill the gaps in the working surface, improving the stability of the equipment and solving the problem of the drill bit 101 shifting due to the slippage of the support component in the prior art. By using the synchronous adjustment mechanism 2, dust and impurities on the outside of the borehole are cleaned, reducing the amount of dust and impurities entering the borehole, reducing drilling resistance, and improving drilling efficiency. This solves the problem in the prior art where external dust and impurities easily enter the borehole, leading to reduced drilling efficiency. By using the synchronous adjustment mechanism 2, the airflow rate inside the cavity 210 is accelerated, allowing the heat inside the body 1 to be expelled. This method dissipates heat from the body 1, improving the service life of the device and solving the problem of reduced service life caused by high heat in the body 1 in the prior art.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a blasting drilling device for blasting construction is provided with multiple sliding grooves 201 and support blocks 202. The multiple sliding grooves 201 and support blocks 202 are distributed in a circumferential array on the body 1, and the drive ring 203 is provided at the output end of the electric telescopic rod 205. In use, the machine body 1 and drill bit 101 are positioned perpendicular to the working surface to be drilled, where the working surface is an uneven rock surface. The inclined portion 206 of the support block 202 preferentially contacts the working surface. The worker vertically drives the machine body 1, drill bit 101, and support block 202 downwards. At this time, the uneven working surface presses against the support block 202. Figure 1 As shown, multiple support blocks 202 are provided. When the support blocks 202 are pressed and slide along the sliding groove 201, the spring 204 is compressed, which drives the drill bit 101 to rotate through the machine body 1. The drill bit 101 performs drilling operations, as shown. Figure 2 As shown, the inclined part 206 is inclined and presents a discontinuous annular shape, so that the end of the inclined part 206 preferentially contacts the gap of the working surface. The discontinuous annular shape prevents the drill bit 101 from slipping in different directions during drilling operations. Depending on the smoothness of the working surface, when the smoothness of the working surface is low, the electric telescopic rod 205 is activated. The electric telescopic rod 205 drives the drive ring 203 to slide along the sliding groove 201, so that the spring 204 is compressed and stores force. When the operator drives the inclined part 206 to contact the working surface, the pressure of the inclined part 206 on the working surface is greater, which improves the anti-slip effect. In this way, the pressure of the inclined part 206 and the working surface can be adjusted according to the smoothness of the working surface, which improves the practicality of the equipment. The adaptive adjustment of the support block 202 and the inclined part 206 by the spring 204 enables the equipment to perform anti-slip treatment on uneven working surfaces, which improves the applicability of the equipment. Furthermore, a drive gear 207 is provided on the drill bit 101, a synchronous shaft 208 is rotatably provided on the machine body 1, a transmission gear 209 is provided on the synchronous shaft 208, a cavity 210 is provided inside the machine body 1, a synchronous gear 211 is provided on the synchronous shaft 208, a gear ring 212 is rotatably provided inside the cavity 210, a rotating ring 213 is provided on the gear ring 212, a fixed shaft 214 is provided on the rotating ring 213, a top plate 215 is rotatably provided on the fixed shaft 214, the fixed shaft 214 and the top plate 215 are connected by a torsion spring, an L-shaped tube 1 216 is slidably provided on the machine body 1, an L-shaped tube 217 is slidably provided on the support block 202, and hollow telescopic rods 218 are provided on the corresponding surfaces of the L-shaped tube 1 216 and the L-shaped tube 217. When drill bit 101 rotates, it drives drive gear 207 to rotate synchronously. Drive gear 207 drives transmission gear 209 to rotate synchronously. Transmission gear 209 drives synchronous shaft 208 and synchronous gear 211 to rotate synchronously. Synchronous gear 211 drives gear ring 212 to rotate synchronously. Gear ring 212 drives rotating ring 213 and top plate 215 to rotate synchronously. Figure 8 As shown, the top plate 215 rotates and impacts the L-shaped tube 216. The elasticity of the torsion spring causes the top plate 215 to rotate adaptively. The impact of the top plate 215 on the L-shaped tube 216 causes vibration in the L-shaped tube 216, hollow telescopic rod 218, L-shaped tube 217, support block 202, and inclined part 206. When the device is drilling, the inclined part 206 contacts the working surface, and the vibration roughens the working surface, thereby improving the roughness of the working surface. The elasticity of the spring 204 drives the inclined part 206 to automatically fill the gaps in the working surface, improving the anti-slip effect and the stability of the equipment. Furthermore, the drive gear 207 and the transmission gear 209 are adapted to each other, the synchronous gear 211 is rotatably mounted on the cavity 210, the synchronous gear 211 and the gear ring 212 are adapted to each other, and the L-shaped tube 216 and the cavity 210 are interconnected. Furthermore, a wedge block 219 is provided on the L-shaped tube 217, and the wedge block 219 and the actuating plate 215 are adapted to each other. The actuating plate 215 is made of rubber. The L-shaped tube 216 vibrates by rotating the top plate 215 and impacting the wedge block 219. The top plate 215 is made of rubber, which makes the impact a flexible impact, thus improving the service life of the equipment. Furthermore, an adjustment ring 220 is slidably provided on the outer side of the body 1, and an arc groove 221 is provided on the adjustment ring 220. The hollow telescopic rod 218 is adapted to the arc groove 221. When the inclined section 206 vibrates and the roughening of the working surface is finished, the adjusting ring 220 is rotated. The adjusting ring 220 drives the Huaxia groove to rotate synchronously. The arc groove 221 rotates and squeezes the hollow telescopic rod 218. The hollow telescopic rod 218 slides along the arc groove 221. The hollow telescopic rod 218 drives the L-shaped tube 1 216, L-shaped tube 217 and wedge block 219 to slide towards the outside of the machine body 1. At this time, the wedge block 219 disengages from the mating with the top plate 215. At this time, the top plate 215 rotates but cannot hit the wedge block 219, so that the equipment stops vibrating and prevents continuous vibration from affecting the drilling accuracy of the drill bit 101. The synchronous adjustment mechanism 2 drives the wedge-shaped part to adaptively fit the working surface, which prevents the device from slipping on uneven working surfaces and improves the applicability of the device. The synchronous adjustment mechanism 2 drives the inclined part 206 to vibrate, which roughens the working surface and improves the roughness of the working surface. The inclined part 206 automatically fills the gaps in the working surface and improves the stability of the device.

[0029] Example 2 further optimizes the blasting drilling device for blasting operations provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, L-shaped tube 1 216, L-shaped tube 2 217 and hollow telescopic rod 218 are all interconnected. A discharge hole 222 is provided in the support block 202, and the discharge hole 222 and L-shaped tube 2 217 are interconnected. Furthermore, the body 1 is provided with a heat dissipation groove 223, which is connected to the cavity 210. A one-way valve 224 is provided in the heat dissipation groove 223, which is used to allow outside air to enter the heat dissipation hole for one-way flow. When the actuating plate 215 rotates, it accelerates the airflow within the cavity 210, causing the air to be discharged into the L-shaped tube 216. Guided by the hollow telescopic rod 218 and the L-shaped tube 217, the air is discharged from the L-shaped tube 217 into the discharge hole 222, where it cleans away dust and impurities from the outside of the borehole. Figure 8 As shown, there are two sets of discharge holes 222. The two sets of discharge holes 222 are distributed on the support block 202 in opposite directions. When the air discharged from the discharge holes 222 cleans the dust and impurities outside the drill hole, the air discharged from the discharge holes 222 is distributed in a single direction. This method prevents the secondary backflow of dust or impurities, reduces the amount of dust and impurities entering the drill hole, reduces drilling resistance, and improves drilling efficiency. The heat generated by the machine body 1 during operation is distributed in the cavity 210 and the heat dissipation holes. By accelerating the air flow rate in the cavity 210, the heat inside the machine body 1 is discharged. This method dissipates heat from the machine body 1 and improves the service life of the equipment. The synchronous adjustment mechanism 2 cleans the dust and impurities on the outside of the borehole, reducing the amount of dust and impurities entering the borehole, reducing drilling resistance, and improving drilling efficiency. The synchronous adjustment mechanism 2 also accelerates the airflow rate inside the cavity 210, allowing the heat inside the machine body 1 to be discharged. This method dissipates heat from the machine body 1 and extends the service life of the equipment.

[0030] The process of using the blasting drilling device for blasting operations provided by this invention is as follows: In use, the machine body 1 and drill bit 101 are positioned perpendicular to the working surface to be drilled. The inclined portion 206 of the support block 202 preferentially contacts the working surface. The operator drives the machine body 1, drill bit 101, and support block 202 downwards. At this time, the uneven working surface presses against the support block 202, causing it to slide along the sliding groove 201. Simultaneously, the spring 204 is compressed, driving the drill bit 101 to rotate via the machine body 1. The drill bit 101 then performs drilling operations. The inclined portion 206 is inclined and forms a discontinuous annular shape, ensuring that the end of the inclined portion 206 preferentially contacts the gap in the working surface. The discontinuous annular shape prevents the drill bit 101 from slipping in different directions during drilling operations. The drill bit 101 rotates and drives... The drive gear 207 rotates synchronously, driving the transmission gear 209 to rotate. The transmission gear 209 drives the synchronous shaft 208 and the synchronous gear 211 to rotate synchronously. The synchronous gear 211 drives the gear ring 212 to rotate, which in turn drives the rotating ring 213 and the jacking plate 215 to rotate synchronously. The jacking plate 215 rotates and impacts the wedge block 219, causing the L-shaped tube 216 to vibrate. The elasticity of the torsion spring causes the jacking plate 215 to rotate adaptively, resulting in vibrations in the L-shaped tube 216, the hollow telescopic rod 218, the L-shaped tube 217, the support block 202, and the inclined section 206. When the device is drilling, the inclined section 206 contacts the working surface, and the vibration roughens the working surface. To improve the roughness of the working surface, the spring 204-1 drives the inclined part 206 to automatically fill the gaps in the working surface. When the inclined part 206 vibrates and finishes roughening the working surface, the adjusting ring 220 is rotated. The adjusting ring 220 drives the Huaxia groove to rotate synchronously. The arc groove 221 rotates and squeezes the hollow telescopic rod 218. The hollow telescopic rod 218 slides along the arc groove 221. The hollow telescopic rod 218 drives the L-shaped tube 216, L-shaped tube 217 and wedge block 219 to slide towards the outside of the machine body 1. At this time, the wedge block 219 disengages from the mating with the top plate 215. The top plate 215 rotates but cannot hit the wedge block 219, causing the equipment to stop vibrating. At this time, the top plate 215 rotates to accelerate the air flow rate in the cavity 210, making... Air from cavity 210 is discharged into L-shaped tube 216. Guided by hollow telescopic rod 218 and L-shaped tube 217, the air flows from L-shaped tube 217 into discharge hole 222. The discharge hole 222 cleans dust and impurities from the outside of the borehole. Two sets of discharge holes 222 are provided, distributed in opposite directions on the support block 202. This ensures that when air is discharged from the discharge holes 222 to clean dust and impurities from the outside of the borehole, the airflow is distributed in a single direction, preventing secondary backflow of dust or impurities. The heat generated by the machine body 1 during operation is distributed within cavity 210 and the heat dissipation holes. By accelerating the airflow within cavity 210, the heat inside the machine body 1 is dissipated.This method is used to dissipate heat from the machine body 1.
