Plate cabinet mounting lifting frame of urban rail transit power supply system

Abstract

The invention relates to a plate cabinet mounting lifting frame of an urban rail transit power supply system. The plate cabinet mounting lifting frame is wholly of a detachable structure. The plate cabinet mounting lifting frame comprises an I-shaped steel beam and first vertical columns, wherein the first vertical columns are arranged below the I-shaped steel beam, the first stand columns are movably connected with second stand columns, and a plurality of positioning pins used for adjusting the heights are arranged on the second stand columns; a pulley block and an electric hoist are movablyconnected below the I-shaped steel beam, universal wheels are arranged below the second stand columns, base steel channels are arranged between the second stand columns and the universal wheels, inclined supporting steel channels for supporting the second stand columns and the base steel channels are arranged between the second stand columns and the base steel channels; and the universal wheels are provided with brake systems. The plate cabinet mounting lifting frame has the advantages that the electric hoist is directly installed on the movable pulley block on the lifting frame to carrying out hoisting installation on a plate cabinet, so that the damage and pollution to a structural beam or the wall top is reduced; the plate cabinet mounting lifting frame is high in structural strength, and not easy to deform; and the plate cabinet mounting lifting frame greatly improves the installation efficiency of the plate cabinet, saves the labor, and reduces the safety risk of aloft operation.

Description

technical field [0001] The invention relates to a panel-mounted lifting frame, in particular to a panel-mounted lifting frame for an urban rail transit power supply system. Background technique [0002] At present, there are two main ways to install traditional panels in urban rail transit. One is to transport the panels to the foundation channel steel with a manual forklift, use a large rope to stabilize the cabinet, and then use crowbars and round steel bars to assist in placing the panels. On the basic channel steel and slowly move to a suitable installation position, this method is time-consuming and labor-intensive, and the most important thing is to cause local damage to the cabinet body, especially the contact part of the crowbar and the cabinet body is likely to cause paint peeling and deformation; and When the center of gravity of a large cabinet is unstable, it is easy to cause it to fall, endangering the safety of the operator and the cabinet.

[0002] At present, there are two main ways to install traditional panels in urban rail transit. One is to transport the panels to the foundation channel steel with a manual forklift, use a large rope to stabilize the cabinet, and then use crowbars and round steel bars to assist in placing the panels. On the basic channel steel and slowly move to a suitable installation position, this method is time-consuming and labor-intensive, and the most important thing is to cause local damage to the cabinet body, especially the contact part of the crowbar and the cabinet body is likely to cause paint peeling and deformation; and When the center of gravity of a large cabinet is unstable, it is easy to cause it to fall, endangering the safety of the operator and the cabinet

Another common installation method is to install chemical anchors or mechanical anchors on the top of the wall directly above the cabinet to be installed, and then fix the chain hoist to lift the cabinet and place it in the correct position. This installation method is more convenient and simple than the first method, but sometimes when the height of the panel cabinet room is very high, high-altitude scaffolding or other methods are used to install anchor bolts on the top of the wall, which is likely to increase the safety risk of high-altitude operations. After the panel cabinet is installed The anchor bolts and inverted chain hoists have to be removed, which increases the safety risk of secondary high-altitude operations. Moreover, when most panels are installed, the top of the wall has been painted. This installation method is also likely to cause pollution on the top of the wall. The most important thing is, When encountering continuous panels, anchor bolts need to be installed directly above each panel, so this installation method is very cumbersome, and the safety risk of working at heights also increases a lot
