Description

Device DLI busbar service.

The utility model relates to repair equipment and can be used for repair and maintenance of trunk busbars mounted on brackets welded to sub wound beams of an overhead crane.

A well-known staircase (see USSR SSR N431291, class E 06С7 / 00, 1975) includes a staircase section consisting of racks, crossbars and a platform. From the site of a famous staircase, it is inconvenient and unsafe to carry out repair work on the maintenance of a pipe installed on brackets welded to crane beams of an overhead crane.

The task to which the claimed utility model is directed is to improve safety.

The problem is solved by the fact that in the device for servicing the busbar trunking, including the stair section with the fence and the platform, the platform is made in the form of a balcony equipped with rollers and installed with the possibility of horizontal movement on the rollers along the guides fixed on opposite sides of the fence, the device is equipped with iol, and also a locking device for locking the balcony in extreme positions.

The inventive utility model differs from the prototype in that the platform is made in the form of a balcony equipped with rollers and is installed with the possibility of horizontal movement on the rollers along rails mounted on opposite sides of the fence, the device is equipped with a floor, as well as a fixing

The device for maintenance of the mineral pipeline is installed under the gallery of the bridge crane of the electric crane and consists of a stair section with a fence I, a platform in the form of a retractable balcony 2 and floor 3. The stair section includes racks 4 and crossbeams 5. The fence 1 and the stair section form a square in plan. the opposite sides of the fence. located perpendicular to the stair section, guides are made 6. Balcony 2 is equipped with rollers 7 mounted on beams 8. Balcony 2 is mounted with the possibility of horizontal movement on the rollers along the guides 6. Two spring-loaded clamps 9 are fixed on the guides b, and two holes 10 are made on the beams 8 for the clamps 9 to fix the balcony in the extreme positions. The stair section with the fence I is fixed with its upper part to the bottom of the gallery of the bridge crane with the help of corners 11 and bolted connections 12, For the descent to the device in the gallery of the bridge crane, a hatch with a cover 13 is made.

When servicing the busbar trunking, bolt connections of current-carrying busbars are monitored and tightened. This extends their service life. For work, the worker, through the hatch with a cover 13. descends to the floor via the crossbars 5. 3. By lifting two spring-loaded clips 9, manually opens the balcony 2 on the rollers along the guides R forward to failure to the busbar 14, In this position, the latches 9 fall into the holes 10 of the beams 8, the balcony 2 is locked. The worker from the floor 3 stands on the base of the balcony 2 and does the work on the bus duct 14L1 at the end of the work. The worker releases the latches 9 and.

floor 3, pushes the balcony 2 back to align with the 4phi rack; this means the latches 9 fall into the other openings 10 of the beams 8 and the balcony opens. According to the floorboard 5, the worker rises to the gallery of the bridge crane, closes the cover 13 of the hatch and leaves the VT bridge crane.

The use of a retractable balcony allows you to have the necessary clearance to the standards between the busbar node and the non-moving steel structure of the bridge crane, which increases the safety precautions for the work performed.
