Hammering noise reduction device for municipal road construction

Abstract

The invention discloses a hammering noise reduction device for municipal road construction, and relates to the technical field of hammering noise reduction. The hammering noise reduction device comprises an impact body and a support, the impact body is movably placed in the support and comprises a shell, a buffer hole is formed in the upper surface of the shell, a plurality of hydraulic cylinders are fixed to the side, close to the buffer hole, of the shell, a connecting plate is fixed to output shafts of the hydraulic cylinders, an impact rod is fixed to one side of the connecting plate, and a mounting groove is formed in the buffer hole; a mounting shell is movably connected into the mounting groove, a sealing strip is fixed to the outer ring of the mounting shell, a buffer is fixed to the inner ring of the mounting shell, and first threaded holes are formed in the surfaces of the mounting shell and the shell. According to the hammering noise reduction device, through the action of the buffer, the friction force between the impact rod and the mounting shell is greatly reduced, the noise generated during friction can be reduced, and compared with a traditional impact hammer, the work volume of the impact hammer can be reduced while the work of the impact rod is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of hammering noise reduction, in particular to a hammering noise reduction device for municipal road construction. Background technique [0002] Hammer pile is one of the commonly used pile types in pile foundation construction of high-rise buildings. The early hammering piles used reinforced concrete prefabricated solid piles, which squeezed the soil a lot, caused the soil to bulge, and had a great impact on the surrounding environment, so they are only suitable for construction in open spaces in the suburbs. In recent years, in order to reduce the damage caused by soil compaction to the surrounding environment, prestressed reinforced concrete pipe piles, steel pipe piles, and H-shaped steel piles have emerged as the times require. The comprehensive technology of detection and protection measures has been greatly developed, which effectively reduces the adverse impact of hammering piles on the surrounding ...

Problems solved by technology

[0003]Although the current technology has solved most of the problems such as soil compaction, the noise problem still exists

"A hammer noise reduction device for municipal road construction" with the application number "CN201922373823.X" discloses a percussion hammer with noise reduction effect. This percussion hammer only adds a layer of sound insulation layer to the hammer pile. The sound insulation layer is fixed in the hammer pile, not only the effect will be greatly reduced after long-term use, but also does not solve the problem that the hammer body may collide with the hammer pile during work
