Description

Technical Field

[0001] This utility model relates to the field of rotary drilling rig technology, specifically an auxiliary device for reducing the noise of rotary drilling. Background Technology

[0002] Noise pollution, as a form of pollution and hazard, is explicitly stated in Article 42 of the Environmental Protection Law. The harm of noise pollution to human health and the environment is receiving increasing attention. Rotary drilling rigs generate continuous noise during operation, which not only affects the physical and mental health of workers but also impacts the lives of nearby residents. The disturbance caused by construction noise limits the drilling rig's operating time, preventing 24-hour continuous operation and severely hindering construction progress.

[0003] Rotary drilling rig construction noise is a point source noise, primarily originating from: the rotation and friction between gears in the power head, the high-speed rotation of the hydraulic motor, the operation of the reducer, and the friction and collision between the drill rod and the power unit; the engine noise of the drilling rig; and the soil being dumped by the drill rod through inertia during the frequent forward and reverse rotation of the drill bit. Currently, there are no comprehensive methods on the market to address these noise issues, resulting in construction noise failing to meet urban construction management requirements.

[0004] Therefore, this utility model provides an auxiliary device for reducing the noise of rotary drilling to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an auxiliary device for reducing the noise of rotary drilling, thus solving the above-mentioned problems.

[0012] Furthermore, the power head arm of an auxiliary device for reducing rotary drilling noise is made of 3mm-4mm thick steel plate.

[0013] Furthermore, the base of the soil-pouring cone of an auxiliary device for reducing rotary drilling noise is a circular steel plate with a diameter of 1200mm and a thickness of 50mm.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Reference Figures 1 to 5 This application provides an auxiliary device for reducing noise in rotary drilling rigs, including a power head body 1, a rig body 2, a soil-insulating cone 3, and an air soundproof wall 4. It also includes a sound insulation device that cooperates with the power head body 1 and the rig body 2. The outermost part of the sound insulation device is a sound insulation board 6. Sound insulation cotton 7 is fixedly connected to the inner side of the sound insulation board 6, and the sound insulation cotton 7 is double-layered. A sound-permeable mesh 8 is fixedly connected to the inner side of the sound insulation cotton 7. A power head arm guard 9 and the rig body 2 are fixedly connected to one end of the inner side of the sound insulation board 6. A soil-insulating cone 3 is provided within the rotation radius of the rotary drilling rig drill bit 5. An air soundproof wall 4 is provided around the working area. The sound insulation board 6 is horseshoe-shaped and made of 1.5mm-2.5mm steel plate. The soundboard 6 has an opening 6 on one side that matches the power head body 1 and an "L"-shaped power head turntable opening; the sound insulation board 6 is equipped with multiple fixing bolts 12; the single layer thickness of the sound insulation cotton 7 is 20mm-24mm; the sound-permeable mesh 8 is made of stainless steel with a round hole diameter of 2.5mm-3.5mm; the power head guard arm 9 is made of 3mm-4mm steel plate; the base of the soil-falling cone 3 is a circular steel plate 15 with a diameter of 1200mm and a thickness of 50mm, and above the circular steel plate 15 is a vertically installed H-shaped steel 14 with a length of 1100mm and a height of 250mm; the cone 13 is a solid steel column with a height of 1500mm and a diameter of 100mm; the air sound insulation wall 4 is a cubic inflatable balloon with a thickness of 400mm and a height of 6000mm.

[0034] The height of the sound insulation device extends 15cm above and below the power head body 1 and the rotary drilling rig body 2; the power head arm guard 9 is matched with the drill rod.

[0035] The sound insulation panel 6 is horseshoe-shaped and made of steel plate. When noise passes through the sound insulation cotton 7, the sound insulation panel 6 will also play a role in sound insulation, effectively preventing noise leakage. Moreover, the outer surface of the steel structure better protects the power head body and the noise reduction device on the rotary drilling rig body, making it more durable. The opening 10 of the power head turntable facilitates the rotation of the power head turntable, and the rectangular hydraulic oil pipe channel 11 facilitates the smooth passage of hydraulic oil pipes on the power head. The fixing bolts 12 make it easy to fix the sound insulation panel to the power head body 1 and the rotary drilling rig body 2.

[0036] The sound insulation cotton 7 is made of glass fiber material and is a double-layered sound insulation cotton 7. The double-layered sound insulation cotton 7 has a 70% higher sound absorption rate than the single-layered sound insulation cotton 7, and the single layer thickness is 20mm-24mm, which can more effectively absorb noise and reduce construction noise to less than 55 decibels, meeting the nighttime construction noise emission standards.

[0037] The sound-permeable mesh 8 is made of stainless steel with round holes of 2.5mm-3.5mm in diameter. Its purpose is twofold: first, to prevent foreign objects from entering the sound insulation cotton 7; and second, to allow construction noise to enter the sound insulation cotton 7 through the sound-permeable mesh 8, so that the sound insulation cotton 7 can absorb it and ensure the sound insulation effect.

[0038] The power head guard arm 9 is made of 3mm-4mm steel plate, and its function is to prevent drill rod mud from splashing onto the sound insulation device and affecting the noise reduction effect;

[0039] The base of the soil-pouring cone 3 is a circular steel plate 15 with a diameter of 1200mm and a thickness of 50mm. Above the circular steel plate 15 is a vertically installed H-beam 14 with a length of 1100mm and a height of 250mm. The steel cone 13 is a solid steel column with a height of 1500mm and a diameter of 100mm. The application of this device eliminates the traditional method of frequently reversing the drill rod to dump mud, effectively reducing the noise generation in this process.

[0040] Air sound barrier 4 is a cubic inflatable balloon with a thickness of 400mm and a height of 6000mm, which further hinders the propagation of generated noise in the air.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] Working principle:

[0043] Overall structure and fit of the sound insulation device:

[0044] The sound insulation device in this complete method comprises, from the outside in, components such as sound insulation panels, sound insulation cotton, and sound-permeable mesh. The outermost layer of the sound insulation panel is made of 1.5mm-2.5mm thick steel plate and is horseshoe-shaped. Double layers of sound insulation cotton (each layer 20mm-24mm thick) are fixedly connected to the inner side. A stainless steel sound-permeable mesh with 2.5mm-3.5mm diameter holes is fixedly connected to the inner side of the sound insulation cotton. One side of the sound insulation panel has an "L"-shaped opening for the power head turntable, which mates with the power head body to facilitate turntable rotation. A rectangular hydraulic oil pipe channel facilitates the passage of hydraulic oil pipes. The sound insulation panel is fixed to the power head body and the rotary drilling rig frame using fixing bolts.

[0045] The power head arm is matched with the drill pipe and is made of 3mm-4mm steel plate, which serves to prevent drill pipe mud from splashing onto the sound insulation device.

[0046] Sound insulation principles of each component:

[0047] Sound insulation panel 6: After noise passes through the sound insulation cotton 7, the sound insulation panel 6 uses its own steel plate material characteristics to play a sound insulation role, effectively preventing noise leakage. At the same time, its steel structure outer surface protects the internal noise reduction components.

[0048] Sound insulation cotton 7: Double-layered sound insulation cotton 7 made of fiberglass material, with a sound absorption rate 70% higher than that of single-layered sound insulation cotton 7, can absorb noise more effectively. Construction noise first enters the sound insulation cotton 7 through the sound-permeable mesh 8 and is absorbed by it to reduce noise transmission.

[0049] Sound-permeable mesh 8: Made of stainless steel with a specific diameter of round holes, the sound-permeable mesh 8 allows construction noise to pass through the sound insulation cotton 7 and be absorbed, while preventing foreign objects from entering the sound insulation cotton 7 and ensuring the normal sound absorption function of the sound insulation cotton 7.

[0050] The noise reduction principle of the soil-pouring cone 3: The base of the soil-pouring cone 3 is a circular steel plate with a diameter of 1200mm and a thickness of 50mm. Above it is a vertically installed H-shaped steel with a length of 1100mm and a height of 250mm. The steel cone 13 is a solid steel column with a height of 1500mm and a diameter of 100mm. Through this specially structured soil-pouring cone 3 device, the traditional method of frequently reversing the drill rod to pour mud is eliminated, thereby effectively reducing the noise generated in the mud-pouring process.

[0051] Air Sound Barrier 4 Noise Reduction Principle: Air Sound Barrier 4 is a cubic inflatable balloon with a thickness of 400mm and a height of 6000mm. By setting it around the work area, it further hinders the transmission of generated noise in the air and reduces the diffusion of noise to the surrounding environment.
