Abstract

The invention provides a shock excitation beam protection device and a resonance crusher, and relates to the field of cement pavement crushing equipment, the shock excitation beam protection device comprises a position sensor arranged on a lifting hydraulic cylinder, and the position sensor is used for detecting the extension length of the lifting hydraulic cylinder; the device also includes a pressure sensor that is arranged at the hinged position of the balance weight beam and the lifting hydraulic cylinder or at one of the hinged positions of the balance weight rod and the balance weight beam as well as the exciting beam and is used for detecting whether the exciting beam is in a suspended state or not. The stroke position of the lifting hydraulic cylinder is detected and the pressure sensor is arranged in a matched mode to guarantee that a hammer head of the shock excitation beam makes reliable contact with the ground, and damage caused by empty vibration of the shock excitation beam is avoided.

Description

technical field

[0001] The invention relates to the field of cement pavement crushing equipment, in particular to an excitation beam protection device and a resonance crusher. Background technique

[0002] Cement pavement crushing construction is to crush the existing cement pavement into particles with large particle size at the bottom and small particle size at the top. After rolling and paving asphalt concrete, it has better average bearing capacity and more uniform deformation, thus extending A construction method for the service life of the pavement. Resonance refers to the phenomenon that the amplitude of the system increases significantly when the excitation frequency of the system is close to a certain natural frequency of the system. The principle of the resonance crushing vehicle is used to break the road surface. The vibration of the resonance crushing vehicle drives the eccentric block to rotate, generating a certain eccentric force, which makes the excitation b...
