Problems solved by technology

At present, the mobile lifting equipment used on land is difficult to meet the requirements of special working conditions such as easy subsidence of the intertidal beach and ebb and flow due to its heavy weight and shallow wading
However, conventional crane ships are not allowed to set foot in the intertidal zone because of their deep water draft.

Abstract

The invention discloses a swing arm type crane barge for mounting wind power equipment, which is characterized by comprising a barge body, wherein the center of the barge body is provided with a portal arm support; the portal arm support is composed of a left and a right truss upright posts, a truss cross beam and a pulley cross beam; the lower ends of the left and the right truss upright posts are hinged with a hinged support on the barge body; the upper parts of the left and the right truss upright posts are respectively connected with a front and a back decks of the barge body through a front and a back radius-changing mechanisms; the lower parts of the left and the right truss upright posts are provided with two sets of hoisting mechanisms, including winding machines; the hoisting mechanisms are provided with wire ropes; the wire ropes bypass two sets of fixed pulley blocks in the pulley cross beam to drive two sets of hook pulley blocks to vertically move; and both sides of the barge body are respectively provided with an impeller-type thruster and a skid mounted thruster. The invention has the characteristics of light weight and light draught, can be aground, and is suitablefor operation and construction in intertidal zones.

Description

technical field [0001] The invention relates to a lifting barge for installing equipment in a shallow water area, and is especially suitable for a lifting barge for installing wind power equipment in an intertidal zone. Background technique [0002] When installing wind power equipment in the intertidal zone, it is necessary to transport the components of the wind turbine to the base of the wind turbine in the intertidal zone, and then carry out the installation work. At present, the mobile lifting equipment used on land is difficult to meet the requirements of special working conditions such as the easy subsidence of the intertidal beach and the ebb and flow of tides due to its heavy weight and shallow wading. Conventional crane ships are naturally unable to set foot in the intertidal zone because of their deep draft and the intertidal zone is a no-go area. Therefore, it is one of the difficult problems to be urgently needed to develop a swing-arm type lifting barge for th...
