Description

Working platform for bridge construction

The present invention is a bridge construction moving work that can perform various operations such as inspection, inspection, maintenance and repair of the lower surface of the bridge, more specifically, a sufficient passage for construction that can easily handle the work of the high part by the operator boarding (B) the bridge's mobile workbench does not require dismantling of the workbench when moving between spans by moving the workbench providing a temporary working floor at regular intervals parallel to the bridge's direction of travel.

Conventional workbench can be divided into fixed and movable installed or suspended under the upper plate of the bridge. In the case of fixed type, temporary members were needed in large quantities because the temporary members were assembled in the form of independent structures. Working on the span spans a lot of time and manpower to dismantle and reassemble the workbench and, in the case of a mobile, separate beams, rails and suspensions above and below the brackets or girders fixed to the outside of the bridge to support the full load of the workbench. There was a disadvantage in that a device or the like must be installed.

An object of the present invention is to span the bridge or girder by rotating at a predetermined interval in parallel to the bridge progress direction while moving the ground work on the bottom surface of the bridge while moving in the grounded state on the bottom of the bridge top plate without a separate temporary member It is to provide a bridge operator mobile workbench that does not require dismantling of the workbench when moving between bridges and spans.

The bridge work device of the present invention, the working platform moving device 10, the rotating pillar 20 installed in the end of the moving device, and consists of a working platform 30 installed on the lower end of the rotating pillar.

The moving device 10 is a steel support 11 installed on the bridge upper plate 300 horizontally, the mobile car 12 is installed on the lower surface of the steel support to move while supporting the vertical load applied to the steel support The counterweight 15 is installed on one side of the steel frame support part 11 to prevent falling, and is composed of a moving wheel 16 supporting the counter weight 15. When moving, it moves forward and backward while being grounded at the bottom of the bridge deck, and when stopped, it can be fixed by installing a separate brake device on the wedge or the moving wheels.

And the support beam 13, the support beam is installed in the longitudinal direction at a certain point on the lower surface of the steel support 11 to disperse the vertical load applied to the mobile car 12 to prevent deformation of the steel support and facilitate the movement Further install the auxiliary wheels 14 connected to the lower surface.

The rotary column 20 is installed at a predetermined distance from the bridge at the opposite end of the counter weight is installed in the steel support 11 of the mobile device. The rotating column is fastened to the upper fixing part 21, the lower fixing part of the upper and the rotating device 22 is provided with a rotating means such as a conventional bearing, the lower rotating part 23 and the lower connecting part connected to the lower part of the rotating device It consists of a workbench support beam 24 fixedly installed in the horizontal direction at the end of the rotating part and a counterweight 25 for balancing one end of the workbench support beam.

The rotary device provides a function to easily rotate the lower rotary unit is installed a work table with a small force built-in bearing. Rotators adopt and use the devices commonly used in machinery.

And as the rotary column 20 is rotated by the rotary device 22, the lower rotary unit 23, the workbench support beam 24, the counter weight 25 and the workbench 30 fixed to the workbench support move together. .

The work bench 30 is provided with a work platform, which is fixed by the work table support 24, and can be formed by interconnecting work benches that can be formed into other forms than trusses using materials such as steel pipes or respective pipes. It can provide sufficient construction aisles or work temporary floors. And a specific point of the counter weight 25 formed on the work table support beam 24 with the steel wires 26 connected to the outside of the upper fixing part 21 of the rotary column and the steel wires 32 connected to the work table, respectively. Connected to each of the steel wire helps to maintain the horizontal balance of the worktable (30). The counterweight 25 may be used by connecting a steel frame member such as H-shaped steel, but may be used by adding a load separately when the eccentricity acts on the work table.

The operation of the present invention bridge working platform will be described.

When the steel wire 31 is connected to the end of the work bench 30 and pulled from the ground, a force that rotates the work bench 30 acts and is installed between the upper fixing part 21 and the lower rotating part 23 of the rotating pillar ( 22) the bearing which becomes the rotating means therein makes sliding contact, and the worktable 30 fixed by the lower end rotating part 23 and the worktable support beam 24 of the rotating column connected to the rotating device 22 rotates, Reposition outside The mobile car on the upper plate of the bridge is operated to move on to the next work, and again, the steel wire 31 of the work bench is pulled in the opposite direction to change the work bench to the lower part of the bridge.

Embodiments of the present invention can be rotated by power by manually rotating the workbench, but by attaching an electric motor to the rotating pillar.

When the scaffold is moved to the next span after one span of work, the work table is rotated at regular intervals in parallel with the bridge heading direction regardless of the change of the head head. The safety of the fall can be prevented by reducing the risk of falling by the tension of the steel wire and the support of the workbench, which provides the point and sufficient working space and maintains the number average form of the workbench.
