Alloy steel resonance girder

Abstract

The invention provides an alloy steel resonance girder, and relates to the technical field of pavement maintenance machinery, the alloy steel resonance girder comprises a vehicle body, and a resonance girder main body is arranged below the left side of the vehicle body; a hammer head is arranged at the front end of the bottom of the resonant beam main body; a fixing base is arranged at the front end of the top of the resonant beam body. The connecting structure of the resonance beam body and the hammer head is simple, and due to the fact that a large number of bolts do not need to be unscrewed and taken down through tools, the assembling and disassembling efficiency of the hammer head is improved; the adjusting lead screw drives the positioning frame to slide up and down along the connecting check block, the height of the resonant beam body can be adjusted, so that the vibration amplitude of the hammer head meets the requirement for crushing different concrete pavements, and the problem that the hammer head and the resonant beam need to be fixed through a large number of bolts during connection is solved; in addition, in the hammering process, resonance is generated between the resonant beam and the vehicle body, and large noise is generated. And the alloy steel resonant beam main body excites the vibrating hammerheads to press the cement board so as to force the cement board to resonate.

Description

technical field [0001] The invention relates to the technical field of road maintenance machinery, in particular to an alloy steel resonance girder. Background technique [0002] In recent years, the traffic load on cement concrete pavements has become increasingly heavy, and various natural factors have been combined for a long time, and many cement concrete pavements have reached the design life, resulting in poor road conditions and cracks and other diseases. This affects the safety and comfort of driving. [0003] However, as far as the current traditional alloy steel resonance beam is concerned, the connection between the hammer head and the resonance beam requires a large number of bolts to fix, the assembly efficiency is low, and the bolts are prone to loosening when hammered for a long time, and it is not easy to be used according to the crushing of different concrete roads. The height of the resonance beam is adjusted, and during the hammering process, the resonanc...

[0003] However, as far as the current traditional alloy steel resonant girder is concerned, the connection between the hammer head and the resonant beam requires a large number of bolts to fix, the assembly efficiency is low, and the bolts are prone to loosening after long-term hammering, and it is not easy to use according to the crushing of different concrete pavements. Adjust the height of the resonant beam, and during the hammering process, the resonant beam and the car body resonate, resulting in greater noise
