Slippage crawling device overturn-preventing system and construction method thereof

Abstract

The invention discloses a slippage crawling device overturn-preventing system and a construction method thereof. The overturn-preventing system comprises skid shoes connected to column feet of arch structures, rails connected to the lower portions of the skid shoes, hydraulic crawling devices, connection rods and overturn-preventing devices. Each hydraulic crawling device is connected between theside face of the corresponding skid shoe and the corresponding rail. Each connection rod is connected between stand columns of the two corresponding adjacent arch structures on the same side. Each overturn-preventing device is connected between the corresponding connection rod and the corresponding hydraulic crawling device. Each overturn-preventing device comprises a movable rail connected to thecorresponding connection rod, an overturn-preventing mechanism connected to the movable rail and a chain block connected to the overturn-preventing mechanism. According to the slippage crawling device overturn-preventing system and the construction method, by arranging the overturn-preventing devices, overturn-preventing protection can be easily conducted on the hydraulic crawling devices in theslippage process; by means of targeted design of the bottoms of the skid shoes and the rails inclining inwards, smooth propulsion of the skid shoes in the slippage process of the arch structures is facilitated; and by arranging the connection rods, integrity of the arch structures is ensured, and stable construction of the whole arch structures is facilitated.

Description

Technical field [0001] The invention belongs to the sliding construction field of arched structures, and particularly relates to an anti-overturning system for a sliding crawler and a construction method thereof. Background technique [0002] During the construction of the arch structure, due to the large size of the truss, it occupies a lot of construction sites. When the construction space is small and the crane is inconvenient for lifting, slipping construction is often used. During the sliding process of the arched structure, in order to avoid excessive lateral displacement of the sliding shoes under the steel arched structure and deviating from the center, the sliding track will be installed inclined to the inside, which will cause the sliding crawler to work There is the possibility of overturning, even pulling up the track, destroying the track, which is not conducive to construction safety. In addition, in the usual sliding construction, the connection between the crawle...
