Description

Technical Field

[0001] This utility model relates to the field of rotary drilling rig technology, and in particular to a self-made green noise reduction tool for rotary drilling rigs. Background Technology

[0002] Rotary drilling rigs are construction machines suitable for hole-forming operations in building foundation engineering. They are mainly suitable for construction in soil layers such as sand, cohesive soil, and silty soil, and are widely used in various foundation constructions such as cast-in-place piles, continuous walls, and foundation reinforcement.

[0003] When a rotary drilling rig is excavating soil, soil clods stick to the inside of the drill bit and cannot fall freely. The drill bit needs to be shaken to dislodge the soil. Therefore, the noise during rotary drilling rig construction mainly comes from the impact sound of the drill bit being shaken in both directions when the drill bit is expelling slag. The noise is relatively loud and will affect the construction environment. Therefore, a self-made green noise reduction tool for rotary drilling rigs is proposed to solve the above problems.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin 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; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-5 As shown, this utility model proposes a self-made rotary drilling green noise reduction tool, including a base plate 1, a support cylinder 2 installed on the top of the base plate 1, a vertical rod 3 movably connected inside the support cylinder 2, a guide mechanism 4 provided on the outside of the vertical rod 3, a fixing box 5 installed on the top of the base plate 1, the fixing box 5 being connected to the outside of the support cylinder 2, a cover plate 6 being hinged to the top of the fixing box 5, a fixing mechanism 7 being provided inside the fixing box 5, the fixing mechanism 7 being connected to the vertical rod 3 for fixing the vertical rod 3, a plurality of evenly distributed barbs 8 being installed on the top of the vertical rod 3, and a plurality of support inclined plates 9 being installed on the outside of the support cylinder 2.

[0024] In this invention, multiple support inclined plates 9 can support the support cylinder 2, ensuring the stability of the support cylinder 2 installation. The support cylinder 2, fixing box 5, cover plate 6 and fixing mechanism 7 can install and fix the upright 3. Multiple barbs 8 can push the soil inside the rotary drilling rig bucket, causing the soil inside the rotary drilling rig bucket to fall off. When the rotary drilling rig bucket is discharging slag, the noise reduction tool is placed next to the rotary drilling rig. After the drill bucket drills out the soil, the drill bucket is inserted into the outside of the upright 3 and multiple barbs 8, so that the multiple barbs 8 can push and cut the soil inside the drill bucket, causing the soil inside the drill bucket to fall off. There is no need to shake and rotate the drill bucket, which greatly reduces the noise of the rotary drilling rig when discharging slag.

[0025] The fixing box 5 and the cover plate 6 can shield and protect the fixing mechanism 7, preventing soil from falling and affecting the fixing mechanism 7. The fixing mechanism 7 can quickly install and remove the pole 3 and multiple barbs 8, making it convenient to transport the noise reduction tool separately and improving the portability of the noise reduction tool.

[0026] In Embodiment 1, the fixing mechanism 7 includes a threaded rod 71, a fixing block 72, a fixing groove 73, a threaded hole 74, a limiting component 75, and a driving component 76. The threaded rod 71 is rotatably connected to the right side wall of the inner cavity of the fixing box 5. The fixing block 72 is located inside the fixing box 5 and extends into the interior of the support cylinder 2. The fixing groove 73 is opened on the outside of the upright 3, and the fixing block 72 is slidably connected to the inside of the fixing groove 73. The threaded hole 74 is opened on the right side of the fixing block 72 and extends to its left side. The threaded rod 71 is threadedly connected to the inside of the threaded hole 74. The driving component 76 is disposed inside the fixing box 5 and is connected to the threaded rod 71 to drive the threaded rod 71 to rotate. The limiting component 75 is disposed on the outside of the fixing block 72.

[0027] When disassembling the upright 3 and the multiple barbs 8, the cover plate 6 is opened, and the threaded rod 71 is rotated by the drive component 76. Under the action of the limiting component 75, the fixing block 72 will not rotate. At this time, under the action of the threaded thrust of the threaded hole 74, the threaded rod 71 will drive the fixing block 72 to move to the right. When the fixing block 72 is disengaged from the fixing groove 73, the upright 3 and the multiple barbs 8 can be taken out from the inside of the support cylinder 2, so that the base plate 1 and the upright 3 can be disassembled, which facilitates the transportation of the noise reduction tool and improves the portability of the noise reduction tool.

[0028] When installing the upright 3 and multiple barbs 8, the upright 3 is slidably connected to the inside of the support cylinder 2 through the guide mechanism 4. Then, the cover plate 6 is opened, and the threaded rod 71 is rotated in the opposite direction through the drive component 76. At this time, the threaded rod 71 will drive the fixing block 72 to move to the right. When the fixing block 72 is slidably connected to the inside of the fixing groove 73, the upright 3 can be fixed through the fixing groove 73 and the fixing block 72 to ensure the stability of the upright 3 installed inside the support cylinder 2.

[0029] In embodiment 2, the drive assembly 76 includes a fixed plate 761, a rotating shaft 762, a driving bevel gear 763, a driven bevel gear 764, and a handwheel 765. The fixed plate 761 is installed on the right side wall of the inner cavity of the fixed box 5. The rotating shaft 762 is rotatably connected to the top of the fixed plate 761 through a bearing and extends to its bottom. The driving bevel gear 763 is installed at the bottom end of the rotating shaft 762. The driven bevel gear 764 is installed on the outside of the threaded rod 71. The driving bevel gear 763 and the driven bevel gear 764 mesh with each other. The handwheel 765 is installed at the top of the rotating shaft 762 and is located inside the fixed box 5.

[0030] When the handwheel 765 is turned, the handwheel 765 will drive the rotating shaft 762 to rotate, the rotating shaft 762 will drive the driving bevel gear 763 to rotate, the driving bevel gear 763 will drive the driven bevel gear 764 meshing with it to rotate, and the driven bevel gear 764 will drive the threaded rod 71 to rotate. The rotating shaft 762 can be installed and supported by the fixing plate 761 and the bearing to ensure the stability of the rotation of the rotating shaft 762.

[0031] In embodiment 3, the limiting component 75 includes two limiting grooves and two limiting blocks. The two limiting grooves are respectively opened on the front and rear side walls of the inner cavity of the fixed box 5, and the two limiting blocks are respectively installed on the front and back of the fixed block 72. The two limiting blocks are slidably connected to the inside of the two limiting grooves.

[0032] The two limiting grooves and two limiting blocks can limit and guide the fixed block 72, ensuring the stability of the fixed block 72's movement. This allows the fixed block 72 to slide stably inside the fixed groove 73. At the same time, the fixed block 72 can also be limited to prevent it from rotating. Thus, the fixed block 72 can be moved by the threaded rod 71 and the threaded hole 74.

[0033] In embodiment four, the guiding mechanism 4 includes two guide grooves 41 and two guide blocks 42. The two guide grooves 41 are both opened on the inner side of the support cylinder 2 and are symmetrically distributed. The two guide blocks 42 are both installed on the outer side of the upright 3. The top of the two guide grooves 41 are connected to the outside. The two guide blocks 42 are slidably connected to the inside of the two guide grooves 41 respectively.

[0034] The upright 3 can be guided by two guide grooves 41 and two guide blocks 42 to ensure the stability of the upright 3 when it is slidably connected to the inside of the support cylinder 2, so that the fixed block 72 and the fixed groove 73 are aligned.

[0035] In embodiment five, the fixing box 5 and the cover plate 6 can protect the fixing mechanism 7, preventing soil from falling onto the fixing mechanism 7 and affecting it. At the same time, magnetic components are installed on the top front of the fixing box 5 and the bottom front of the cover plate 6. The magnetic components can be magnets, which can be used to connect the fixing box 5 and the cover plate 6.

[0036] Working principle:

[0037] This homemade rotary drilling rig noise reduction tool works by first placing the base plate 1 next to the rotary drilling rig, then sliding the upright 3 to the inside of the support cylinder 2 via the guide mechanism 4. Next, open the cover plate 6 and turn the handwheel 765. This causes the threaded rod 71 to rotate, and under the force of the threaded rod, the threaded rod 71 moves the fixing block 72 to the left. When the fixing block 72 is slidably connected to the fixing groove 73, the upright 3 is fixed by the fixing groove 73 and the fixing block 72. Then, close the cover plate 6. After the drill bit drills out the soil, insert the drill bit into the outside of the upright 3 and multiple barbs 8. The barbs 8 then push and cut the soil inside the drill bit, causing the soil to fall out without needing to shake or rotate the drill bit, thus greatly reducing the noise during the rotary drilling rig's mud discharge process.

[0038] When it is necessary to disassemble the upright 3 and the multiple barbs 8, clean the dirt off the top of the base plate 1, then open the cover plate 6 and turn the handwheel 765 in the opposite direction so that the threaded rod 71 will drive the fixing block 72 to move to the right. When the fixing block 72 is disengaged from the fixing groove 73, the upright 3 can be taken out from the support cylinder 2, thereby separating the base plate 1 from the upright 3, which facilitates the transportation of the noise reduction tool and improves the convenience of the noise reduction tool.

[0039] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
