Description

Sliding rail cabinet

Technical Field

The invention belongs to the technical field of rail transit vehicles, and particularly relates to a sliding rail cabinet.

Background

The electric cabinet of the existing rail transit vehicle is internally provided with equipment such as a storage battery or a super capacitor which needs to be frequently maintained and overhauled. The equipment has large weight and large quantity and is generally in a block shape. The equipment is ensured to be stable in position and firm in wiring during installation, so that dangerous accidents caused by vibration and displacement can be prevented. In general, the vibration of the equipment easily causes the phenomenon of weak and unreasonable wiring, and the phenomena of equipment ignition, wire burning, fire and the like are extremely easy to cause. As shown in fig. 1 of the specification, in order to prevent vibration of the equipment 6 installed in the electrical cabinet, the equipment 6 is generally fixed by using a pressing plate 7, so as to ensure safety and reliability of the equipment 6. However, the number of the devices is large, the devices are distributed in layers, the depth of the cabinet is very deep, and regular maintenance and overhaul are needed, so that the devices are required to be dragged out to observe whether the appearance of the devices bulges or not and whether the related electrical parameters of the devices meet the operation requirements or not, and a large amount of manpower and material resources are required to be spent for disassembling a large number of pressing plates 7 and cables to finish the maintenance and overhaul work of the devices.

And, power supply unit still need change after using certain time, perhaps upgrade it and reform transform, and present electrical apparatus cabinet structure is according to power supply unit volume customization, if change other not unidimensional power supply unit in later stage, can lead to whole electrical apparatus cabinet to scrap, simultaneously along with the requirement of capacity improves, the weight increase of equipment.

Further, the first reinforcing ribs, the second reinforcing ribs and the third reinforcing ribs are arranged at equal intervals.

Further, the front end of support is equipped with the limiting plate, the rack body includes many stands, be equipped with on the stand that is located rack body front end with limiting plate complex mounting, the limiting plate passes through the fastener with the mounting and is connected, and the restriction the slide rail stretches out, through setting up limiting plate and mounting, can prevent effectively that the equipment box stretches out under vibrations, causes the accident.

Still further, be equipped with the slide rail mounting panel between the stand at both ends about the rack body, the stiff end of slide rail is installed on the slide rail mounting panel.

Still further, the third strengthening rib is in slide rail mounting hole department of support has seted up the breach, the fastener on the slide rail mounting support can effectively be avoided to the breach.

Still further, equipment box bottom is equipped with the second strengthening rib that many horizontal directions extended, the bottom extension end of the corresponding first strengthening rib in equipment box both ends passes through second strengthening rib (33) is connected to constitute the exoskeleton of equipment box. According to the invention, the first reinforcing rib and the second reinforcing rib are matched to form the outer framework of the equipment box, so that the bearing performance of the equipment box is greatly improved.

In addition, the length direction of support lateral wall face is equipped with two rows of slide rail mounting holes, every support is last to be installed two the slide rail. The double-slide rail type cabinet can be better suitable for heavy load.

The sliding rail cabinet has the following advantages: the invention adopts a modularized cabinet structure, is easy to install, maintain and repair and is easy to upgrade and reform. Adopt double-deck slide rail, adopt unsmooth type strengthening rib cooperation between support and the equipment box, not only can effectually improve bearing and stability, can also prevent to place the equipment vibrations in the equipment box, realize the heavy load and guarantee the safety of equipment simultaneously, greatly promote the reliability of rack.
