Device for conveying concrete pipe in sleeve

The utility model provides a device for conveying a concrete pipe in a casing pipe, which is characterized in that two steel rails are arranged in the casing pipe and are vertical to the wall of the concrete pipe because the space in the casing pipe is narrow, and the included angle between the two steel rails is 60 degrees. Wherein the steel rail is welded on a steel plate belt which is 20cm wideand 2cm thick and is installed on the wall of the sleeve in advance, and the steel plate is connected with the wall of the sleeve through an expansion bolt. Two-point hoisting is adopted for the pipeline, before hoisting, a special pipe conveying trolley is placed on a rail in advance, and the trolley is formed by simply machining a steel plate and wheels. Transportation of the concrete pipe in the sleeve can be achieved through a chain block or a winch. A steel plate base plate is placed at the pipeline mounting position in advance to serve as a support for adjusting a pipeline mounting jack. 本实用新型提供一种套管中运送混凝土管装置，包括
