Screen cabinet bottom frame

Abstract

The invention discloses a screen cabinet bottom frame. The screen cabinet bottom frame comprises a screen cabinet supporting frame, a combined type mounting base arranged at the bottom of the screen cabinet supporting frame, and a combined type fixed bracket fixed on the screen cabinet supporting frame, wherein the combined type mounting base comprises a plurality of base mounting blocks; the combined type fixed bracket comprises a plurality of fixed mounting blocks; and the screen cabinet bottom frame also comprises fasteners connected with the base mounting blocks and the fixed mounting blocks. By applying the screen cabinet bottom frame disclosed in the invention, the mounting modes of the combined type mounting base and the combined type fixed bracket are diversified, so that obstaclesof welding joints and the like can be avoided to a certain degree, thereby enlarging the mounting spaces of the screen cabinet and realizing diversified mounting spaces; and therefore, the types anddimensions of screen cabinets which can be mounted are increased, and naturally, universality of the screen cabinet bottom frame is improved.

Description

technical field [0001] The invention relates to the field of auxiliary support equipment, in particular to a screen cabinet bottom frame. Background technique [0002] Screen cabinets generally include power supply cabinets, power distribution cabinets, signal cabinets, etc., and are often used on electric locomotives. The screen cabinet usually consists of two parts: the skeleton and the electrical equipment. The electrical equipment mainly refers to most of the low-voltage electrical equipment and control equipment. Therefore, the screen cabinet is an important part of the electric locomotive. [0003] When in the electric locomotive, the screen cabinet is usually fixed on the screen cabinet bottom frame, and the screen cabinet bottom frame is fixed on the bottom frame of the electric locomotive, so that the screen cabinet is fixed on the electric locomotive. Existing screen cabinets often rely on fasteners such as bolts and nuts to pass through the waist-shaped mounting ...

AI Technical Summary

Problems solved by technology

Existing screen cabinets often rely on fasteners such as bolts and nuts to pass through the waist-shaped mounting holes on the bottom frame of the screen cabinet to achieve fixation. However, the waist-shaped mounting holes on the bottom frame of the screen cabinet are usually fixed before installing the screen cabinet. The processing is completed, so when the screen cabinet is installed, the position of the waist-shaped mounting hole on the bottom frame of the screen cabinet is fixed. Naturally, the types and sizes of the screen cabinets that can be installed on the bottom frame of the screen cabinet are relatively limited, and the versatility is poor.

[0004] In addition, considering that the screen cabinet needs to have good anti-vibration performance, it is necessary to avoid welding seams and threading holes on the bottom frame of the electric locomotive as far as possible when installing the bottom frame of the screen cabinet to avoid interference. Naturally, the bottom frame of the screen cabinet The installation position is limited, resulting in limited installation space for screen cabinets, so the types and sizes of screen cabinets that can be installed are limited, and the versatility is poor
