Subway top suspension device

Abstract

The invention discloses a subway top suspension device, which comprises a mounting seat, wherein a suspension framework is welded at the bottom of the mounting seat, a connecting seat is welded at a left side of the bottom of the suspension framework, a jack is formed in the connecting seat, a lamp holder is welded at the left side of a cross rod, a lamp body is arranged at the left side of the lamp holder, a lamp body fixing device is welded at the bottom of the left side of the suspension framework, a hook mechanism is welded at a right side of the bottom of the suspension framework, and a fixing mechanism is welded at the bottom of the right side of the suspension framework. By the adoption of the subway top suspension device, the lamp body can be fixed and maintained by maintenance personnel when the lamp body is maintained through the lamp body fixing device, the lamp body does not need to be held by hands for maintenance, the maintenance is easy, the maintenance efficiency is improved, the lamp body can be fixed when illuminating by the hook mechanism, the phenomenon that the lamp body is shaken and damaged in a running process of the subway is avoided, and the service life of the lamp body is prolonged.

Description

technical field [0001] The invention relates to the technical field of subway vehicles, in particular to a subway top suspension device. Background technique [0002] Subway is a rapid and large-capacity urban rail transit mode that is gradually developed along the surface railway system. Its lines are usually laid in underground tunnels, and some are outside the city center, from underground to ground or The way of laying on the viaduct, but the existing subway top suspension device still has the following problems, 1. When the maintenance personnel repair the lamp body, they cannot fix the lamp body for maintenance, and need to hold the lamp body for maintenance, which is more troublesome , which reduces the efficiency of maintenance. 2. When the lamp body is illuminated, it cannot be fixed. The lamp body is prone to shaking and damage during the subway running, which reduces the service life of the lamp body. 3. When other parts need to be connected with the suspension I...

[0002] Subway is a rapid and large-capacity urban rail transit mode that is gradually developed along the surface railway system. Its lines are usually laid in underground tunnels, and some are outside the city center, from underground to ground or The way of laying on the viaduct, but the existing subway top suspension device still has the following problems, 1. When the maintenance personnel repair the lamp body, they cannot fix the lamp body for maintenance, and need to hold the lamp body for maintenance, which is troublesome , which reduces the efficiency of maintenance. 2. When the lamp body is illuminated, it cannot be fixed. The lamp body is prone to shaking and damage during the subway driving, which reduces the service life of the lamp body. 3. When other parts need to be connected with the suspension It is more troublesome to connect the skeleton, which increases the labor load of the installers and reduces the efficiency of the installation
