Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with specific embodiments.

[0028] Such as figure 1 shown. The invention discloses an anti-seismic support and hanger based on a variable stiffness spring for vibration reduction, which includes a diagonal brace, a vertical brace 12.1, and a horizontal brace 12.2;

[0029] The lower ends of the diagonal struts and vertical struts 12.1 are connected to the left end of the horizontal struts (12.2), wherein the diagonal struts are hinged to the horizontal struts 12.2, and the vertical struts 12.1 are connected to the horizontal struts 12.2 through screws; The upper ends of the diagonal struts and the vertical struts 12.1 are respectively connected with the structural layer 14.1;

[0030] The diagonal struts are inclined 40°-45° relative to the vertical struts 12.1; the vertical struts 12.1 and the horizontal struts 12.2 are perpendicular to each other;

[0031] The diagonal strut is a compos...

Abstract

The invention discloses a shock-resistant supporter and hanger based on variable-stiffness spring vibration reduction. The shock-resistant supporter and hanger comprises an oblique strut, a vertical strut and a horizontal strut; the oblique strut serves as a main shock-resistant assembly and adopts a superimposed spring shock absorber; the superimposed spring shock absorber mainly comprises threesprings in different lengths and two sleeves; and with such structure, a variable-stiffness flexible shock-resistant mechanism is provided and the shock-resistant supporter and hanger has a good vibration reduction ability and shock resistance. The three superimposed springs in different lengths can be subjected to stiffness adjustment passively according to external excitation, and can be appliedto the shock resistance and the vibration reduction of a pipe network supporter and hanger in a bad service environment more. The shock-resistant supporter and hanger has the functions of the shock resistance, the vibration reduction and the reinforcement; the structure is simple, the production is convenient, the mounting is convenient, and the cost is reduced substantially; the adaptability isgood, the stiffness can be adjusted passively according to the external excitation, and the superimposed springs can be applied to the bad service environment; and the shock-resistant supporter and hanger has the good variable-stiffness flexible shock-resistant mechanism, so that the shock resistance and vibration reduction efficiency is improved substantially.

Description

technical field [0001] The invention relates to the field of installation and fixing of pipelines in construction mechanical and electrical engineering, in particular to an anti-seismic support and hanger based on variable stiffness springs for vibration reduction. Background technique [0002] Anti-seismic supports and hangers have been widely used in the installation and fixing fields of construction electromechanical engineering, aiming at reducing the damage caused by earthquakes to electromechanical engineering. At present, rigid support and hangers are commonly used in pipeline projects in water, electricity, and wind plants in my country. In areas with strong vibration, the support and hanger will generate strong vibrations, which will seriously affect the safety of production and transportation. Once the support and hanger fails, the pipeline will collapse. Accidents will cause irreparable losses. "Code for Seismic Design of Building Mechanical and Electrical Enginee...
