RU2460839C1 - Device to move scaffolding along mounted span cable-stayed girders - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: device comprises rolling tracks, fixed on the upper plane of span cable-stayed girders and having holes made with an even pitch, a trolley moving along rolling racks, where the scaffolding rests, a bracket fixed on the trolley, a stop fixed with the help of a split joint in openings of rolling tracks, and a hoist, the rope of which is fixed by one end to the bracket, and with the other one - to the stop. The novelty is the fact that it is equipped with an additional similar stop and a hoist, the bracket is arranged as a horizontal beam that rests in a movable manner by means of a roller support against rolling tracks and having horizontal holes arranged along the entire length with the even pitch. Stops have horizontal holes in the upper part, which are coaxial with the holes in the horizontal beam and where a detachable support bolt is installed. Free ends of hoist ropes are combined with each other by means of a coupling resting as capable of sliding against a horizontal beam.

EFFECT: improvement of device.

Description

The invention relates to bridgebuilding and can be used in devices for moving scaffolds along mounted span beams.

A device is known for moving scaffolds along mounted stiffness beams of a span structure, including skating paths fixed on the upper plane of span stiffness beams and having openings made with the same pitch, a cart on which scaffolding rests, an arm fixed to the cart, an emphasis fixed with detachable connections in the holes of the ski paths, and a winch, the cable of which is attached at one end to the bracket and the other to the stop [1].

The disadvantage of this device is the difficulty of reconfiguring it when changing the direction of movement of the scaffolds and insufficient reliability due to the lack of an additional safety winch.

An object of the present invention is to provide an easily reconfigurable device having high reliability.

The problem is solved due to the fact that the device for moving scaffolds along the mounted stiffness beams of the span, including skating paths fixed on the upper plane of the stiffness beams of the span and having holes made with the same pitch, a cart on which the scaffolding rests, an arm fixed to the trolley, an emphasis fixed with a detachable connection in the holes of the skiing paths, and a winch, the cable of which is attached at one end to the bracket and the other to the emphasis, is equipped with similar to a stop and a winch, the bracket is made in the form of a horizontal beam, movably supported by a roller support on the ski path and having horizontal holes made with the same pitch along their entire length, while the stops have horizontal holes coaxial with the holes in the horizontal beam and in which a removable stop bolt is located, and the free ends of the winch cables are interconnected by means of a coupling supported with the possibility of sliding on a horizontal beam.

The invention is illustrated by drawings, where:

- figure 1 shows a device for moving scaffolds along the mounted stiffness beams span, side view;

- figure 2 shows a device for moving scaffolds along the mounted stiffness beams span, view along the axis of the bridge;

- figure 3 shows the mounting of the stop to the ski paths and a horizontal beam, node A in figure 1.

On the upper plane of the mounted stiffness beams 1 of the span along the axis of the bridge, skating paths 2 are mounted, on which scaffolds are supported by means of trolley 3. Trolley 3 is equipped with a bracket made in the form of a horizontal beam 5, movably supported by roller support 6 on skating path 2. B horizontal beam 5 and 8 of the tracks 2 are made with a uniform pitch of the holes 7 and 8. The stops 9 are fixed using detachable joints 10 with their lower ends in the holes 8 of the tracks 2. In the upper part of the stops 9 are made rstia 11, coaxial with the holes 7 of the horizontal beams 5. When combining the holes 7 and 11, a detachable stop bolt 12 is placed in them. The cables of the winches 13 and 14 are attached at one end to the stops 9, and the other free ends are interconnected by couplings 15, which are supported by the ability to slide on horizontal beams 5.

The device operates as follows. If it is necessary to move the scaffolds 4 to the axis of the joint 16, one of the stops 6 is fixed with a removable stop bolt 12 on the horizontal beam 5, and the other stop 6 is fixed using detachable joints 10 in the holes 8 of the driving paths 2. They work with a traction winch 13 and are moved by horizontal beam 5 trolley 3 with scaffolds 4, while the winch 14 is safety. After horizontally moving the beams 5 to the stop, the paths 2 are moved to a new parking lot, and the stops 6 are fixed in the next holes 7 and 8, after which the process of moving the scaffolds 4 is repeated. If necessary, the shifting of the scaffolds 4 to the other side is fixed on the horizontal beam 5 another emphasis 9 with the simultaneous fixation of a similar emphasis 6 on the ski tracks 2. In this case, the traction winch 14 becomes, and the winch 13 becomes a safety winch.
