Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to a construction device and method for reducing construction noise. Background Art

[0002] During the construction of a pile pit, a pile pit construction device is required to drive a drill bit to rotate at high speed through a motor to achieve the purpose of pressing down to open a hole. For example, the existing patent with publication number "CN217460589U" discloses "a pile pit construction device, including a bracket device, a construction device provided on one side of the outer surface of the bracket device, the construction device including a device plate, a bottom plate provided on one side of the outer surface of the device plate, a motor provided on the upper side of the outer surface of the device plate, and a motor shaft provided on the lower side of the outer surface of the motor..." It can be seen that the application describes a common pile pit construction device;

[0003] However, when the pile pit construction device in the above patent is actually used, since there is no corresponding sound insulation and noise reduction structure designed at the bottom, the violent noise generated when the drill bit moves down and contacts the ground will be directly emitted outward, causing a large construction noise and affecting the entire construction environment. At the same time, the debris generated during drilling is also easy to splash outward, which has certain disadvantages. For this reason, the present invention proposes a construction device and method for reducing construction noise. Summary of the Invention

The disassembly and assembly mechanism also includes a limit block rotatably arranged on the side of the noise reduction and sound insulation cover, the bottom end of the limit block extends to one side of the annular base and fits with the surface of the T-shaped plug, a circular protrusion is fixed on the surface of the T-shaped plug, and a circular card hole is provided at the bottom end of the limit block, and the circular protrusion is embedded in the circular card hole, a side rod is fixed on the side of the noise reduction and sound insulation cover, and the limit block is rotatably sleeved on the surface of the side rod, an end plate is fixed to one end of the side rod, and a spring is also sleeved between the surface of the side rod relative to the limit block and the end plate.

[0007] Preferably, a guide hole is provided on the surface of the outer ring seat, and a positioning structure is also provided between the guide column and the outer ring seat, and the positioning structure includes a rotating support block rotatably mounted on the surface of the guide column, and a push block notch is provided on the inner wall of the guide hole, and an annular groove is provided on the surface of the guide column, and a T-shaped slider is slidably provided in the annular groove, and one end of the T-shaped slider extends to the surface of the guide column and is fixed to the rotating support block, and the positioning structure also includes a rubber pad, a circular protrusion and a circular groove, and a rubber pad is also fixed to the side of the bottom surface of the outer ring seat relative to the guide hole, and the bottom of the rubber pad is provided with an integrated circular protrusion, and the top surface of the rotating support block is provided with a circular groove, and the circular protrusion is embedded in the circular groove.

[0008] A construction method using the construction noise reduction device comprises the following steps:

[0009] Step 1: Install the noise reduction and sound insulation cover on the top of the bottom ring seat, and connect it stably with the ring base through the disassembly and assembly mechanism;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figures 1 to 4 , which is the first embodiment of the present invention, and this embodiment provides a technical solution: a construction device for reducing construction noise, comprising a bottom ring seat 1 and a top plate assembly 2 movably mounted on the top of the bottom ring seat 1 through two guide columns 8, a motor 3 is mounted on the top of the top plate assembly 2 through bolts, and an output shaft 31 is provided at the bottom end of the motor 3, the bottom end of the output shaft 31 passes through the bottom of the top plate assembly 2, and a drill bit 4 is installed, after the motor 3 is started, the drill bit 4 will rotate at high speed through the output shaft 31 to perform a drilling operation, and the top plate assembly 2 can subsequently move downward and bring the drill bit 4 into contact with the ground for drilling construction, the top plate assembly 2 comprises an outer ring seat 21, an inner tray 22 and a connecting block 23, a plurality of connecting blocks 23 are welded and fixed between the inner tray 22 and the outer ring seat 21, so that the outer ring seat 21 and the inner tray The disks 22 can be fixed together, and the motor 3 is fixed to the top center of the inner tray 22 by bolts. A noise reduction and sound insulation cover 5 is installed on the top surface of the bottom ring seat 1. The noise reduction and sound insulation cover 5 can be made of transparent acrylic material. The drill bit 4 is covered on the inside by the noise reduction and sound insulation cover 5 to wrap, protect and reduce noise. The top of the noise reduction and sound insulation cover 5 passes through the top of the inner tray 22. The surface of the noise reduction and sound insulation cover 5 is provided with a plurality of strip sliding openings 51 corresponding to the connecting block 23, and the connecting block 23 is located in the strip sliding openings 51, so that the noise reduction and sound insulation cover 5 will not affect the normal lifting and lowering of the top plate assembly 2. An annular base 9 is welded and fixed to the top surface of the bottom ring seat 1, and a disassembly and assembly mechanism 7 is provided between the noise reduction and sound insulation cover 5 and the annular base 9 for subsequent disassembly, maintenance and cleaning of the noise reduction and sound insulation cover 5.

[0024] Among them, the disassembly and assembly mechanism 7 includes an annular slot 71, a T-shaped plug block 72 and a limit socket 73. The top surface of the annular base 9 is provided with an annular slot 71 corresponding to the noise reduction and sound insulation cover 5. The bottom end of the noise reduction and sound insulation cover 5 is inserted into the annular slot 71. The bottom end surface of the noise reduction and sound insulation cover 5 is provided with a limit socket 73 corresponding to the T-shaped plug block 72. The T-shaped plug block 72 is installed on one side surface of the annular base 9, and one end of the T-shaped plug block 72 passes through the limit socket 73 to achieve the reduction. The stable limit of the noise reduction sound insulation cover 5 ensures the convenience of disassembly and assembly of the noise reduction sound insulation cover 5. Subsequently, it is only necessary to remove the top plate assembly 2 from the top of the bottom ring seat 1, and then pull out the T-shaped plug 72, and the noise reduction sound insulation cover 5 can be directly moved up and removed. The disassembly and assembly mechanism 7 also includes a limit block 74 rotatably arranged on the side of the noise reduction sound insulation cover 5. The bottom end of the limit block 74 extends to one side of the annular base 9 and fits with the surface of the T-shaped plug 72, which can provide a stable barrier to the T-shaped plug 72 in daily use. The stopper 74 has a circular block 75 welded on the surface of the T-shaped plug 72, and a circular card hole 76 corresponding to the circular block 75 is provided at the bottom end of the stopper 74. The circular block 75 is embedded in the circular card hole 76 to ensure that the stopper 74 will not move away from the end of the T-shaped plug 72 by itself during daily use, thereby ensuring the limiting stability of the T-shaped plug 72. The side of the noise reduction and sound insulation cover 5 is fixed with a side rod 77, and the stopper 74 is provided with a circular card hole 76 corresponding to the circular block 75.

An end plate 78 is welded and fixed to one end of the side rod 77. A spring 79 is sleeved between the surface of the side rod 77 relative to the limit stopper 74 and the end plate 78. Subsequently, the limit stopper 74 only needs to be moved sideways to move the circular protrusion 75 out of the circular locking hole 76. The bottom end of the limit stopper 74 can be rotated away from the end of the T-shaped plug-in block 72, and the T-shaped plug-in block 72 can be inserted and removed. The surface of the outer ring seat 21 is provided with a guide hole 211 corresponding to the guide column 8.

[0025] A construction method using a construction device for reducing construction noise comprises the following steps:

[0026] Step 1: First, install the noise reduction and sound insulation cover 5 on the top of the bottom ring seat 1, and stably connect it to the annular base 9 through the disassembly and assembly mechanism 7;

[0027] Step 2: Then install the top plate assembly 2 on the top of the bottom ring seat 1, so that the top end of the guide column 8 can pass through the top of the top plate assembly 2, and the drill bit 4 is located inside the noise reduction and sound insulation cover 5;

[0028] Step 3: Move the bottom ring seat 1 to a suitable construction area and adjust its orientation to ensure that the subsequent drilling positions are correct;

[0029] Step 4: Release the support limit of the positioning structure 6 on the top plate assembly 2, then start the motor 3 to make the drill bit 4 rotate at high speed. At this time, slowly move the top plate assembly 2 downward so that the bottom end of the drill bit 4 contacts the ground and the drilling operation is carried out;

[0030] Step 5. Due to the wrapping enclosure of the noise-reducing and sound-isolating cylinder cover 5, the drill bit 4 and the drill hole are both on the inner side of the noise-reducing and sound-isolating cylinder cover 5, which can greatly reduce the noise generated during drilling and the construction noise of the device. At the same time, it can prevent debris from splashing during drilling and improve construction safety.

[0031] Example 2

[0032] See also Figures 1 to 5 , which is the second embodiment of the present invention, is based on the previous embodiment, but differs in that the positioning structure 6 can be provided to effectively support the top plate assembly 2 before drilling, thereby bringing convenience to the operator's construction operation.

[0033] Specifically, a positioning structure 6 is also provided between the guide column 8 and the outer ring seat 21. The positioning structure 6 includes a rotating support block 61 rotatably mounted on the surface of the guide column 8. The rotating support block 61 can provide a stable support and lifting effect on the outer ring seat 21. When drilling is required, the rotating support block 61 only needs to be rotated to align with the push block notch 62 to perform the lifting operation of the top plate assembly 2. The inner wall of the guide hole 211 is provided with a push block notch 62 corresponding to the guide hole 211. The surface of the guide column 8 is provided with an annular groove 64, and a T-shaped slider 63 is slidingly provided in the annular groove 64. One end of the T-shaped slider 63 extends to the surface of the guide column 8 and is fixed to the rotating support block 61, so that the rotating support block 61 can rotate smoothly on the surface of the guide column 8. The positioning structure 6 also includes a rubber pad 6 5. Circular protrusion 66 and circular groove 67. A rubber pad 65 is glued and fixed to one side of the bottom surface of the outer ring seat 21 relative to the guide hole 211. The bottom of the rubber pad 65 is provided with an integrated circular protrusion 66. The circular protrusion 66 is also made of rubber material and can undergo elastic deformation. A circular groove 67 corresponding to the circular protrusion 66 is provided on the top surface of the rotating bracket 61. The circular protrusion 66 is embedded in the circular groove 67, which can play an auxiliary limiting role for the rotating bracket 61 and prevent the rotating bracket 61 from rotating by itself. Subsequently, you only need to push the rotating bracket 61 with force to cause the circular protrusion 66 to be squeezed out of the circular groove 67, and then the rotating bracket 61 can be rotated to align with the push block notch 62, thereby performing the lifting operation of the top plate assembly 2.
