Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments.
Referring to fig. 1-4, the utility model provides a low noise hydraulic hammer protective housing, this protective housing has two parallel mainboards 1, and the bottom welding of two mainboards 1 has bottom plate 4, and the top welding has flange 5, flange 5 fixedly connected with connector 6. And a front coaming 2 and a rear coaming 3 which are opposite are fixedly arranged between the inner surfaces of the front side and the rear side of the two main boards 1. The connector 6 is provided with two parallel side plates, a support plate 12 is welded between the two parallel side plates, a groove is formed in the bottom of the support plate 12, and a ridge-shaped pressing plate 11 which is raised in the middle and extends from two sides is arranged in the groove. A closed shell is formed between the two main boards, the front and rear enclosing plates, the pressing plate and the bottom plate, so that the low-noise hydraulic hammer protective shell has the relative condition isolated from the outside, the noise is reduced from the transmission path, and the effects of sound insulation and noise reduction are achieved. The upper surface of the bottom plate 4 is fixedly provided with a first damping block 7, the lower surface of the pressing plate 11 is fixedly provided with a second damping block 8, and the inner wall of the shell above the first damping block 7 is fixedly provided with a wear-resistant block 9. The first damping block 7 is in close contact with the inner wall of the shell, and circular through holes are formed in the centers of the first damping block and the shell; the second damping block 8 is cross-shaped, and a circular through hole is formed in the center; the wear-resisting piece 9 has set up the three-layer along the vertical direction of casing, at a certain distance of interval, and four respectively have been arranged on every layer, respectively fixed mounting on four surfaces of shells inner wall. The wear-resistant block 9, the first damping block 7 and the second damping block 8 are all made of polyurethane. Because polyurethane has excellent shock attenuation, shock-absorbing capacity, good compressive load resistance ability and deformation resilience performance, so the snubber block one and snubber block two can absorb the vibration that the hydraulic hammer during operation produced, have reduced the noise from the source. In addition, in order to reduce the weight of the shell, lightening holes 10 are formed in the two main plates.
