Portable movable construction platform device capable of crossing obstacles for bridge outer side breast boards

Abstract

The invention relates to a portable movable construction platform device capable of crossing obstacles for bridge outer side breast boards, which is formed by combining a support and a hanging basket, three rollers are arranged below the support and make contact with a breast board to bear a vertical force, three vertical rods capable of being drawn up and down are arranged on the rear portion of the support, lateral rollers are arranged on the inner sides of the lower ends of the vertical rods, a horizontal force is provided by contacting with the side surface of the breast board; the upper portion of the hanging basket is connected with the support through four hooks. When the device in use, a bracket is firstly placed, and then the hanging basket is hung on the bracket and is fixedly connected with the bracket through pins; vertical rods are sequentially lifted to pass through when the device transversely moves to the stand column, the bracket is kept in a horizontal force bearing state all the time, and the three vertical rods bear horizontal force after smoothly passing through the stand column. The device is suitable for treating concrete diseases of the breast board on the outer side of the viaduct, and is particularly suitable for construction on the outer side of the rail transit viaduct with the breast board provided with the cable support stand column.

Description

technical field [0001] The invention relates to a mobile construction platform device, in particular to a mobile construction platform device suitable for construction on the outside of rail transit elevated bridges with cable support columns on the railing. Background technique [0002] With the development of the city, problems such as bulging and falling of the concrete structure of the outer railing of the rail transit viaduct appear, and tend to be serious, and the demand for renovation construction will gradually increase. [0003] Restricted by construction conditions, the current commonly used construction methods are to use climbing vehicles and scaffolding. However, many bridges are located directly below rivers and major traffic intersections, etc., and conventional platforms cannot be erected, and transportation within the subway section is inconvenient. Standing on the railing The safety risk of heavy objects is high, and a portable and efficient platform device...

[0003] Restricted by construction conditions, the current commonly used construction methods are to use climbing vehicles and scaffolding. However, many bridges are located directly below rivers and major traffic intersections, etc., and conventional platforms cannot be erected, and transportation within the subway section is inconvenient. Standing on the railing The safety risk of heavy objects is high, and a portable and efficient platform device for treating diseases of bridge outer railings is needed
