Embodiment Construction
[0051] The present invention will be more clearly and completely described below by way of a preferred embodiment with reference to the accompanying drawings, but the present invention is not limited to the scope of the described embodiment.
[0052] Such as Figure 1-5 As shown, this embodiment provides a noise reduction device for a concrete pump truck 1, which includes a housing mechanism 2, the housing mechanism 2 includes a plurality of housing divisions, and the housing divisions are detachable connected, and a plurality of shell subsections can be spliced together and jointly enclosed to form a sound-proof cavity, which is used to accommodate the body part of the concrete pump truck 1 . The noise reduction device realizes the sound insulation of the entire concrete pump truck 1 by covering it outside the car body part of the concrete pump truck 1, so that it does not perform targeted noise reduction on every noise-generating part of the pump truck. The operation and ...

The invention discloses a noise reduction device for a concrete pump truck. The noise reduction device comprises a shell mechanism. The shell mechanism comprises a plurality of shell parts which are detachably connected, wherein the plurality of shell parts can be spliced and jointly form a sound insulation cavity in a surrounding and covering manner; and the sound insulation cavity is used for containing a truck body part of the concrete pump truck. According to the noise reduction device for the concrete pump truck, the shell mechanism is arranged and covers the outer portion of the truck body part of the concrete pump truck to achieve sound insulation of the whole concrete pump truck, and therefore targeted noise reduction does not need to be conducted on each part, generating noise, ofthe pump truck, the structure and operation are simple, and time and cost are saved; the shell mechanism is formed by splicing the multiple shell parts, rapid forming of the sound insulation cavity is facilitated, dismounting and mounting are convenient, and the noise reduction device is not limited by the arrangement position; and in addition, the shell mechanism is formed by splicing the plurality of shell parts, adaptive adjustment can be conducted according to the sizes of different pump trucks, and good economical efficiency and use convenience are achieved.
Description
technical field [0001] The invention relates to a noise reduction device for a concrete pump truck. Background technique [0002] With the continuous development of construction technology, concrete pump trucks are widely used in the construction industry. With the acceleration of urban renewal and transformation, concrete pump trucks will also produce high-decibel and continuous noise while improving operating efficiency, which will affect the normal work and life of residents around the construction site. According to the analysis of the working principle of the concrete pump truck, the sound source of the noise is mainly in the following parts: (1) The hydraulic pump system (core part), due to component deformation, air mixing into the pipeline, pipeline blockage, valve vibration, etc. (2) The delivery pump pipe (connecting part), air mixed into the delivery pipe, pipe wall friction impact, connection port vibration and other reasons generate noise; (3) Engine (power par...
