Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is further described:

[0012] As shown in the accompanying drawings, a suspension and damping structure of a fan for a rail vehicle includes a fan support frame 1 and a shock absorber 2, and is characterized in that a mounting beam 3 and a suspension beam 4 are provided, and the upper end of the mounting beam 3 The center is vertically fixedly connected with the fan support frame 1, and the two sides of the upper end of the fan support frame 1 are vertically fixedly connected with the suspension beam 4 respectively, and the suspension beam 4 is provided with a shock absorber 2 so that the shock absorber 2 On both sides of the fan support frame 1 and the installation beam 3, the vibration isolation of the fan transmitted through the fan support frame 1 is weakened, so that the vibration of the installation beam 3 and its external mechanisms are not or rarely affected by the fan.

Abstract

The invention relates to the technical field of fans, in particular to a damping structure for ventilator hanging for a rail locomotive. The damping structure comprises a ventilator supporting frame and dampers. The damping structure is characterized by being provided with a mounting beam and a hanging beam; the center of the upper end of the mounting beam is vertically and fixedly connected with the ventilator supporting frame; and the two sides of the upper end of the ventilator supporting frame are vertically and fixedly connected with the hanging beam, the dampers are arranged on the hanging beam, and the dampers are arranged on the two sides of the ventilator supporting frame and the mounting beam and used for isolating and weakening vibration, transmitted by the ventilator supporting frame, of the ventilator, and the mounting beam and external mechanisms of the mounting beam are not affected or rarely affected by the ventilator in vibration. By the adoption of the structure, the damping structure has the beneficial effects of being simple, convenient to manufacture, high in damping performance, low in weight, high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a suspension and damping structure for a fan used in rail vehicles. Background technique [0002] In the existing hanging fan installation, the installation structure is usually direct hoisting, or a more complicated shock absorbing structure is used, which mainly includes fan support frame, shock absorber and hanging bracket, and the hanging bracket structure is complicated. , The structural strength requirements are extremely strict. In the design, materials with high strength and large thickness are selected, and the welding methods are complicated in the process. The welding quality requirements are strict, resulting in unreasonable structures, complicated manufacturing processes, and high manufacturing costs. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a suspension and damping structure ...
