Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude hoisting, in particular to a high-altitude hoisting device for a heat-absorbing tube panel of a heat-absorbing tower. Background Art

[0002] The molten salt tower solar power station uses numerous heliostats to reflect and accumulate solar radiation into the molten heat absorber at the top of the heat absorption tower to heat the molten salt fluid. At the same time, by configuring a heat storage system, the solar thermal power generation unit can maintain a stable power generation load, and the change in light intensity has little effect on it. If there is a sufficiently large capacity heat storage system, the unit can generate electricity continuously at full load for 24 hours. In addition, the molten salt tower solar power station has the characteristics of large scale, small heat loss and high temperature, so it can be built on a large scale.

[0003] The absorber is the core equipment of the heat absorption tower. At present, the absorber is mainly composed of several absorber tube panels. During the construction of the heat absorption tower, a tower crane is required to cooperate with a lifting beam to lift the absorber tube panels to the required height of the tower top and install them one by one. The absorber tube panels currently used are generally more than ten meters long and weigh several tons. After being fixed to the rear supporting steel frame, the weight distribution is not uniform. During the lifting process, the uneven weight distribution may cause the absorber tube panel and the lifting beam to tilt as a whole, which is not convenient for docking with the equipment on the top of the tower. For this reason, we propose a high-altitude lifting device for absorber tube panels of heat absorption towers. Utility Model Content
