Description

Dig soon and bore sound insulation device for construction

Technical Field

The utility model relates to the technical field of rotary drilling rigs, in particular to a sound insulation device for rotary drilling rig construction.

Background

The rapid development of urban rail transit brings convenience to the life of people. In the process of construction of urban rail transit, vibration and noise problems caused by the urban rail transit cause close attention of people, and particularly, when the urban rail transit is constructed in environment-sensitive areas such as businesses, houses, offices, hotels and hospitals, the urban rail transit not only causes great vibration and noise pollution problems to the surrounding environment, but also affects physical and psychological health of constructors. Therefore, the problem of controlling vibration noise pollution in the construction process becomes an important problem to be solved urgently in the field of environmental protection. The rotary drilling rig is mechanical equipment widely used for foundation construction engineering of municipal construction, highway bridges, high-rise buildings and the like, and a large amount of noise is generated due to friction between a drill bit and soil rocks during construction, so that great influence is generated on the surrounding environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a sound insulation device for rotary drilling construction, which aims to solve the problems in the background technology.

To achieve the above object, the present invention provides the following solutions: comprises a bottom frame, trundles, a sound-proof cover, a connecting plate, fastening bolts, sound-absorbing cotton, a clapboard, a damping spring and porous cotton; the caster wheels are arranged on the lower side surface of the underframe; the sound-proof cover is welded on the bottom frame; the connecting plate is welded on the side surface of the sound-proof shield; the fastening bolt is arranged on the connecting plate; the sound absorption cotton is fixed on the upper surface of the sound insulation cover through screws; the baffle plate is arranged on the inner side surface of the sound-proof cover; the damping spring is arranged between the partition plates; the porous cotton is arranged on the inner side surface of the sound-proof shield and positioned between the partition boards.

As a preferable technical scheme of the utility model, the underframe, the sound-proof cover, the sound-absorbing cotton, the partition board and the porous cotton can be divided into two semicircular parts from the middle, and the two connecting plates are fixed by fastening bolts when being combined. Because the drilling part at the tail end of the rotary drilling rig is larger, the bottom caster is convenient to move in a construction environment and is separated into two parts, the rotary drilling rig motor part and the drill bit part can be wrapped more conveniently, and noise is prevented from being directly arranged in the surrounding environment

As a preferred technical scheme of the utility model, the sound-absorbing cotton is made of polyester fiber, and a layer of sealing ring is additionally arranged during installation. The drill rod part is laminated with the cotton internal diameter of inhaling the sound mutually, inhales and installs the sealing washer additional between sound cotton and the sound-proof housing, promotes to increase and seals the effect, improves and inhales the cotton sound absorption efficiency of inhaling the sound.

As a preferred technical scheme of the utility model, the partition plate is made of rubber and has five layers, and ten damping springs are uniformly distributed on the circumference between every two layers of partition plates. The motor rotates the noise that produces and the noise that the drill bit and earth friction produced, increases the reflection number of times through the baffle, adds and establishes damping spring, reduces the vibrations of inside baffle, reduces inside air flow rate.

As a preferred technical scheme of the utility model, the porous cotton is made of terylene hollow fibers, four pieces of the porous cotton are arranged between every two layers of partition boards, and the thickness of the porous cotton is one third of the thickness of the partition boards. The multiple reflected sounds pass through the porous wool, absorbing part of the noise, and reducing the noise that can pass through the sound enclosure.

Compared with the prior art, the utility model has the beneficial effects that: the rotary drilling rig can reduce noise generated by friction between the drill bit and soil during the working process of the rotary drilling rig, and avoids the noise from directly polluting the surrounding environment by reducing the internal air flow rate, absorbing the noise and the like. Meanwhile, the movable type concrete wall is convenient to move on a construction site, is convenient to mount and dismount, and is suitable for various construction occasions.

Detailed Description

Example 1

As shown in fig. 1 to 3, before the construction, take off fastening bolt 5, wrap up two parts respectively on the drill bit of digging the brill soon from both sides, its drill bit part is located sound-proof housing 3, the drill bit produces a large amount of noises with the friction of earth rock, arouse air vibrations, it flows to drive the air, most noise is multiple reflection in sound-proof housing 3, absorb by porous cotton 9, the part is upwards transmitted through multiple reflection, it absorbs to inhale cotton 6 of sound, reduce the noise that directly transmits in the environment around.

As a preferred technical scheme of the utility model, the partition plate 7 can be selected to be a circle or a regular polygon with the inner diameter according to the appearance of the drill bit, is attached to the drill bit as much as possible, covers the sound source of the drill bit, absorbs noise through multi-section reflection, and reduces the pollution of the noise to the surrounding environment.

As a preferred technical scheme of the utility model, according to the power of the rotary drilling bit, damping springs 8 with different rigidity can be selected, and the damping springs are arranged on the partition plate 7 and are close to the inner ring of the partition plate 7. The impact force part that the during operation vibrations of digging soon and bore turns into damping spring 8's elasticity, and damping spring 8 shrink drives baffle 7 and removes, reduces the whole range of vibrations of noise insulation, avoids the connecting piece to lead to becoming flexible or droing because of vibrations, increases life.

As a preferred technical scheme of the utility model, if the ground of the construction site is flat, the caster can be detached, the sealing performance of the sound-proof cover 3 is improved, and the pollution of noise to the surrounding environment is further reduced.
