Abstract

The invention provides a preparation method of a vibration exciting beam of a pavement crushing vehicle. The preparation method comprises the steps of 1, casting and molding a beam body in a mold cavity; 2, hot forging the beam body; 3, tempering the beam body; 4, finishing the beam body to a preset size, and rounding all broken line positions; and 5, lapping the surface of the beam body to ensurethat the surface roughness is lower than Ra1.6 [mu]m, thereby obtaining the vibration exciting beam of the pavement crushing vehicle through the steps. By adopting the scheme, the service life of thevibration exciting beam under the vibration working condition can be greatly prolonged. The broken line positions of the beam body are all of rounded structures, and micro cracks can be prevented from being generated as fracture source regions. The vibration exciting beam has low surface roughness by adopting a surface lapping process, and the micro cracks under the vibration working condition can be avoided.

Description

technical field

[0001] The invention relates to the field of cement pavement crushing construction equipment, in particular to a method for preparing an excitation beam of a pavement crushing vehicle. Background technique

[0002] At present, the equipment used for crushing cement pavement includes single-hammer type, door-knife type and multi-hammer type equipment for crushing. When crushing, it will exert a strong impact on the ground, make noise, and it is difficult to meet the requirements of crushing depth and crushing quality. High energy consumption and low efficiency.

[0003] Chinese patent document CN206052519U describes a cement concrete pavement resonance crusher, which crushes the pavement by adopting a resonance mode, with low noise and high efficiency. The cement concrete pavement is crushed by using this vibration excitation method, and the part transmitting the excitation vibration is an excitation beam, and the excitation beam is easy to break under the wo...
