Abstract
The utility model discloses a noise-reduction and dust-prevention movable operating room which is in a box body structure with walls on four side and caster wheels at the bottom and comprises a bottom frame and noise absorbing baffles. The walls are formed by splicing the noise absorbing baffles; the lower ends of the noise absorbing baffles are fixed on the bottom frame; and the noise absorbing baffles are noise absorbing honeycomb baffles. The utility model adopts the noise absorbing honeycomb baffles to replace the original noise absorbing baffles and can ensure that noises generated by an air pick for filed operation have the medium-high frequency spectrum characteristic; in addition, the noise absorbing honeycomb baffles are reduced by 35 percent in overall weight and are more attractive in appearance on the basis of meeting requirements of noise insulation and absorption and compression strength of original absorbing baffles; especially, with the random shaping characteristic of the noise absorbing honeycomb baffles, the utility model no longer adopts upright posts and the top frame structure, thereby the modular combination function is fulfilled, and the utility model is used in the operating occasions of a small pickaxe machine.
Description
Technical field
The utility model relates to a kind of construction noise reduction facility, is specifically related to a kind of closure construction scene that is used for, and reaches the mobile operating room of noise-reducing and dustproof effect.
Background technology
Along with the raising of the rapid development of national economy and the people's material and cultural life level, environmental protection problem is more and more important.Large-scale city infrastructure and pipe engineering are had higher requirement to construction noise.The anti-therapy of People's Republic of China's pollution from environmental noise with construction noise as one of four big noise problems, clear and definite requirement has been proposed, wherein-90 pairs of construction noises of standard GB 12523-90 and GB12524 have been made concrete regulation again, and restriction strong noise equipment uses and is defined in must not construct night.And the construction of pipe engineerings such as electric power often needs operation around the clock, and noise and dust that construction site and construction equipment produce can bring pollution to surrounding environment.
Another piece of the applicant application number is 200720072892.1 patent application, a kind of noise-reducing and dustproof mobile operating room is disclosed, its main framework is a frame construction, the not only making of framework, transportation are installed inconvenient, and be not easy to the modularization of product, it is limited to adapt to the construction occasion, and the sound absorption accommodation of the acoustical board of original structure is limited in addition.
The utility model content
The technical problems to be solved in the utility model provides a kind of product modular, wide accommodation, noise-reducing and dustproof mobile operating room that acoustically effective is good be convenient to, to overcome the above-mentioned defective that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
A kind of noise-reducing and dustproof mobile operating room, it is the body structure that has the four sides wall, the bottom is provided with castor, it is characterized in that, comprise under(-)chassis and acoustical board, described four sides wall is spliced to form mutually by acoustical board, and the lower end of described acoustical board is fixed on the under(-)chassis; Described acoustical board is a sound-absorbing honeycomb plate.
By above disclosed technical scheme as can be known, the utility model is by substituting original abatvoix to sound-absorbing honeycomb plate, the scope of its frequency spectrum that absorbs sound substantially is: six frequencies such as 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz, the noise that pneumatic pick produces that can satisfy field operation is the spectral characteristic based on medium-high frequency.Sound-absorbing honeycomb plate in addition, on the basis of satisfying original acoustical board sound insulation, sound-absorbing effect and compressive resistance etc. substantially, overall weight alleviates 35%, and profile is more attractive in appearance; The random molding characteristics that particularly cooperate this plate to have can be saved column and top mount structure, thereby have realized the modular combination function of work-room, and can be used for the operation occasion of small-sized pick machine in good time.The utility model work-room only needs the base channel steel frame can build the entire job chamber, has saved the making and the transportation of top frame and has installed.
Description of drawings
Fig. 1 is the structural representation of the utility model mobile operating room.
Fig. 2 is the horizontal end face structure schematic diagram figure of acoustical board.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model noise-reducing and dustproof mobile operating room, it is the body structure that has the four sides wall, comprise under(-)chassis 2 and acoustical board 2, described four sides wall is spliced to form mutually by acoustical board 2, described under(-)chassis is a chan frame, and the bottom of under(-)chassis is provided with Moving caster, and the lower end of described acoustical board 2 is inserted in the notch of channel-section steel and is fixed on the under(-)chassis 2; Described acoustical board 2 be sound-absorbing honeycomb plate its be layer structure, its structure ecto-entad is followed successively by: coloured coating aluminium sheet 21, honeycomb plate 22, perforation aluminum soleplate 23, sound absorption mineral wool 24, glass fiber portion 25, perforation color steel 26.The perforated percentage of described perforation color steel 26 is greater than 23%, and piercing aperture is more than or equal to 3mm.
The corner that connects at adjacent acoustical board 2 interconnects by corner acoustical board 3.
Consider the ventilated of the interior construction environment of work-room, acoustical board is adopted in the part, top, makes the top hollow out (after testing, even the top also reaches the noise reduction requirement without acoustical board) of casing, plays top sound insulation, sound absorption.The upper end of every sidewalls acoustical board 2 of work-room all increases the inclination acoustical board (5) of 45 degree that inwardly are inclined upwardly, be interconnected to form up-small and down-big upside down funnel shape between the inclination acoustical board (5), vertical or noise section that oblique line makes progress are absorbed and reflex in the work-room, increased top sound insulation area.Giving up of top frame structure makes work-room top Teng go out bigger space, thereby can allow work-room be applied to more construction occasions; When needed, also can carry additionally the top acoustical board, reduce the influence of noise to a greater degree environment
The utility model is owing to saved column, therefore work-room can not be restricted in the framework, the accessory of having realized a unit process chamber can be formed 21 kinds of various combinations, and (wherein some seems measure-alike, as: 2500*3000 and 3000*2500, but the position of door is different), wherein 10 kinds is common combinations, and cost performance of product has significant improvement.In addition, if the work-room of 2 (or more than) unit is arranged, can the work-room of several unit be spliced into one by increasing some annexes and accessory, king-size work-room can be applicable to long needs apart from engineerings such as ground level road excavations.
Following table is an acoustical behavior examining report of the present utility model:
