High-speed rail large box girder internal formwork cleaning device

Abstract

The invention discloses a high-speed rail large box girder internal formwork cleaning device. The cleaning device comprises rolling brushes used for cleaning the surface of an internal formwork and further comprises a frame body capable of moving along a rail, wherein a top cleaning device capable of moving transversely is arranged on the upper side of the frame body, side cleaning devices capable of moving longitudinally are arranged on the two sides of the frame body, a spraying device is arranged on one side of the frame body, the frame body comprises stand columns vertically arranged on the two sides and a truss arranged at the tops of the two stand columns, inverted-splayed track frames matched with the side wall of the internal formwork in shape are arranged on the inner sides of the two stand columns, the top cleaning device is arranged on the truss, and the side cleaning devices are arranged on the track frames on the two sides. The cleaning device has the advantages that due to the arrangement of splicing joints, the length of the truss can be changed, high-speed rail large box girder internal formworks of different specifications can be cleaned, the one-to-many cleaning function requirement can be met, and due to the arrangement of adjustable brush arms, the cleaning device can adapt to the size change or angle change of the girder shape.

Description

technical field [0001] The invention relates to the field of formwork cleaning equipment, in particular to a formwork cleaning device for the inner formwork of a large box girder of a high-speed railway. Background technique [0002] With the rapid development of China's high-speed rail, it is gradually leading the world. The high-speed rail large box girder has become an indispensable basic project. Because of its standardization, prefabrication, and adaptability, it can not only greatly reduce the construction period, but also effectively improve the performance of the high-speed rail bridge. Provide strong support for smooth and safe operation. [0003] Due to the characteristics of the beam itself in the high-speed railway large box girder pre-casting: after pouring, it must go through the process of demoulding, maintenance, beam lifting, beam storage, transportation, erection, etc. In the process of demoulding, maintenance, and beam lifting, it is extremely easy to get...

AI Technical Summary

Problems solved by technology

[0004] So far, the templates of most bridges have been manually cleaned, because of their relatively large height, width and span, and irregular shapes, which have caused great difficulties in the cleaning work

The cleaning work has the disadvantages of high labor intensity, low safety, and long construction time. At the same time, it may cause damage to the formwork and even cause secondary pollution

After cleaning, the job of re-spraying the release agent on the surface of the formwork also has the same difficulty
