Wind power generation climbing hoisting crane

Abstract

The invention relates to a wind power generation climbing hoisting crane, which belongs to hoisting machinery and consists of a machine stem, an upper holding clamp, a lower holding clamp, a hydraulic boom and a pulley hook connected with a hinging rope, wherein the upper end and the lower end in a cavity of the machine stem are provided with chain wheels which are in meshed connection by using a ring chain. The clamp body of the lower holding clamp is fixed at the lower end of the machine stem, and the clamp body of the upper holding clamp is sleeved on the outer wall of the machine stem through movable fit and an inner seat of the clamp body is provided with a ratchet to mesh the chain; and the upper holding clamp is provided with a jaw driven by a hydraulic tank, and the lower holding clamp is provided with a jaw driven by the hydraulic tank. The wind power generation climbing hoisting crane can be widely applied to large-sized wind generating sets such as the hoisting of the parts of a tower tube, an engine room, a wind wheel hub and the like, is applicable to hoisting operations of high altitude and superaltitude heavy equipment, is not limited by the maximum lifting height and fields, can perform hoisting operations on flat grounds, hillsides and sea surface, is electromechanically integrated with high automation degree, can be controlled on the ground, has light weight, is convenient for assembly and disassembly, transition and transportation, and has high operational efficiency.

Description

technical field [0001] The invention relates to a heavy-duty hoisting machine, in particular to a climbing hoisting crane for wind power generation. Background technique [0002] Natural resources such as wind energy, solar energy, and tidal energy are renewable energy sources in nature, which are inexhaustible and inexhaustible. With the depletion of fossil fuels such as coal, oil, and natural gas, the development and utilization of renewable and environmentally friendly energy has become the only way recognized by the world. However, due to the high cost of wind power generation equipment, high construction and installation costs, and large one-time investment, the resulting cost and electricity price is higher than that of conventional thermal power and hydropower. For example, the existing hoisting process is more complicated and needs to be completed by using multiple heavy lifting facilities and supporting equipment. Take the installation of a 1500KW wind turbine as a...
