Across-river lower-hanging bridge crossing device in canal channel

Abstract

The invention discloses an across-river lower-hanging bridge crossing device in a canal channel. The device is characterized in that double lines (two ferry devices with the same structure) are arranged in parallel, and the double lines are connected by a transfer platform at both ends to realize the circular transport of a ferry in two ship routes; each bridge crossing device comprises a ship lift, wherein a crane is arranged at the top of each ship lift; a ship lifting pallet placed between the side walls of the ship lifts and used for supporting the ferry and a ship reception chamber is driven to lift by the crane; the two ends of a longitudinal girder horizontally spanning above the river are connected with the ship lifts to form an integral structure; a rail is arranged on the longitudinal girder; a moving trolley is slidably arranged on the rail; a joint is arranged at the lower end of the moving trolley; and a rigid rack connected with the joint is arranged on the top of the ship reception chamber. The across-river lower-hanging bridge crossing device disclosed by the invention is ingenious in structure and easy to implement. The ferry devices can directly lift vessels and transport the vessels to the other side of the river, and is least affected by the scouring and silting changes of the Yellow River channel; and double-line arrangement is adopted to conveniently realize the circular transfer of a fleet.

Description

technical field [0001] The invention relates to a water transportation infrastructure construction project, in particular to an underhanging bridge crossing device for crossing a river in a canal waterway. Background technique [0002] The Beijing-Hangzhou Grand Canal is the ancient canal with the longest mileage and the largest project in the world, and also one of the oldest canals. Together with the Great Wall and Karez, it is called the three great projects of ancient China. It is a great project created by the working people in ancient China . The Grand Canal starts from Yuhang (now Hangzhou) in the south, ends in Zhuojun (now Beijing) in the north, passes through the four provinces of Zhejiang, Jiangsu, Shandong, and Hebei, and the two cities of Tianjin and Beijing, and runs through the five major water systems of the Haihe River, the Yellow River, the Huaihe River, the Yangtze River, and the Qiantang River. , with a total length of about 1797 kilometers. The use of ...

Problems solved by technology

The upper-span plan of the aqueduct is technically feasible and has similar experience. However, because there is water along the entire line of the aqueduct, the high-level waterway of the Grand Canal and the large tonnage of ships will lead to an overly large aqueduct structure and high cost
