Abstract

The invention provides a device and method for automatically controlling excitation frequency of a concrete pavement resonance crushing vehicle, wherein one end of an excitation beam mounting frame ishinged on a crushing engineering vehicle body through a pin shaft, an excitation beam is mounted at the bottom of the excitation beam mounting frame through a first hinge seat, an excitation hammer is arranged at one end of the head part of the excitation beam, an excitation motor is arranged at the other end of the head part of the excitation beam, the excitation motor is connected with an excitation hydraulic pump, an acceleration sensor used for detecting the natural frequency of the road surface is arranged at head end of the excitation beam mounting frame, and the acceleration sensor isconnected with a signal acquisition and analysis module through a first signal line. The natural frequency information of the road surface is acquired through acquisition and analysis, the natural frequency information of the road surface is transmitted to a control system, the output pressure of the excitation hydraulic pump and the flow of the excitation hydraulic pump are adjusted through the control system to change the rotating speed of the excitation motor, the excitation frequency of the resonance crushing vehicle is controlled, so that the excitation frequency of the resonant crushingvehicle is consistent with the natural frequency of the road surface.

Description

technical field [0001] The invention belongs to the field of crushing equipment for concrete pavement, and in particular relates to an automatic control device and method for excitation frequency of a concrete pavement resonance crushing vehicle. Background technique [0002] At present, the vibration of the road resonance crushing vehicle is driven by the excitation motor to rotate the eccentric block on the excitation beam to generate a certain eccentric force, which makes the excitation beam deform periodically and drives the hammer head to vibrate up and down. Therefore, adjust the vibration of the resonance crushing vehicle. The vibration frequency is actually to adjust the speed of the vibration motor. The vibration frequency adjustment of the road surface resonance crushing vehicle is mainly carried out by skilled workers, that is, one person drives the resonance crushing vehicle, and the other observes the road surface crushing near the hammer head, and the observer ...
