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 appliance cabinet of the existing rail transit vehicle is provided with equipment such as a storage battery or a super capacitor and the like which needs to be maintained and overhauled frequently. The equipment has heavy weight and large quantity, and is generally block-shaped. The equipment is ensured to be stable in position and firm in wiring during installation so as to prevent dangerous accidents caused by vibration and displacement. Generally, the vibration of the equipment easily causes the phenomena of false wiring but not real wiring, and ignition of the equipment, burning of wires, ignition and the like. As shown in fig. 1, in order to prevent the equipment 6 installed in the electrical cabinet from shaking, the equipment 6 is generally fixed by a pressing plate 7, so as to ensure the safety and reliability of the equipment 6. However, due to the fact that the number of the devices is large, the devices are arranged in a layered mode, the cabinet is deep in depth, and regular maintenance and repair are needed, so that whether the surface of the device bulges or not can be observed only by dragging out the devices, and whether the related electrical parameters meet the operation requirements or not can be measured, and therefore a large amount of manpower and material resources are needed to finish maintenance and repair work of the devices when a large number of pressing plates 7 and cables are disassembled.

And power supply unit still need change after using a certain period, perhaps upgrade transformation to it, and present electrical cabinet structure all is customized according to power supply unit's size, if other not unidimensional power supply unit of later stage change, can lead to whole electrical cabinet to scrap, along with the requirement of capacity improves simultaneously, the weight of equipment increases.

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

And furthermore, a notch is formed in the sliding rail mounting hole of the support through the third reinforcing rib, and the notch can effectively avoid a fastener on the sliding rail mounting support.

Furthermore, the bottom of the equipment box is provided with a plurality of second reinforcing ribs extending in the horizontal direction, and the bottom extending ends of the first reinforcing ribs corresponding to the two ends of the equipment box are connected through the second reinforcing ribs (33) to form an outer framework of the 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, two rows of slide rail mounting holes are formed in the length direction of the side wall surface of the support, and two slide rails are mounted on each support. Adopt two slide rail formula cabinets can better adapt to the heavy load.

The sliding rail cabinet has the following advantages that: 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 the strengthening rib cooperation of concave-convex type between support and the equipment box, not only can effectual improvement bearing and stability, can also prevent to place the equipment vibrations in the equipment box, realize the safety of heavy load assurance equipment simultaneously, greatly promote the reliability of rack.
