Damping device of impact type machine foundation

Abstract

The invention discloses a damping device of an impact type machine foundation. A spherical rubber block and a damper are adopted for combined damping. The spherical rubber block is formed by means ofthe method that a plurality of layers of spherical rubber plates and spherical steel plates are embedded, stuck and vulcanized, and the vertical rigidity of the spherical rubber block can ensure bearing force on an impact type machine. Meanwhile, the inherent frequency of the impact type machine foundation can be adjusted to get away from the impact load frequency, and the inlaid spherical steel plates of the spherical rubber block can effectively restrain lateral expansion of rubber and provide radial restraining counterforce to limit horizontal displacement of the impact type machine so as to ensure the operation stability of the impact type machine. Through the layout scheme of the damper, the spatial size and mechanical performance of the damping device can be optimized, and the impactenergy of the impact type machine is rapidly consumed to enable the impact type machine to rapidly recover to a balancing position. Therefore, the damping device can provide effective frequency shiftand energy consumption effects, so that the damping function of the impact type machine is achieved, the operation stability of the impact type machine is ensured, and the vibration influence of operation of the impact type machine on surroundings can also be reduced.

Description

technical field [0001] The invention belongs to the technical field of vibration control, in particular to a vibration damping device for an impact machine foundation. Background technique [0002] With the development of industrial modernization, the degree of mechanization of various production activities is becoming more and more extensive. A large number of power machines are put into processing and production, which makes the production efficiency higher and higher. However, the normal operation stage of power machines will cause obvious damage to the ground or objects in the factory building.

[0002] With the development of industrial modernization, the degree of mechanization of various production activities is becoming more and more extensive. A large number of power machines are put into processing and production, which makes the production efficiency higher and higher. However, the normal operation stage of power machines will cause obvious damage to the ground or objects in the factory building. The shaking affects the working environment of the staff and the normal use of precision instruments and equipment, and also affects the surrounding buildings

In particular, some large-scale impact machines have caused serious environmental vibration problems during normal operation. With the development of social economy and the improvement of people's quality of life, the impact of vibration on the environment must be controlled, but there are existing vibration reduction devices. Due to the complex structure, high cost, and limited implementation conditions, it is urgent to propose a practical and effective vibration reduction measure to reduce the environmental vibration caused by the operation of impact machines.
