Abstract

The invention discloses a large-slab girder stacking beam installation device, which solves the technical problem that the existing upper and lower stacking beams are not tightly connected, which easily leads to joint cracking of the upper and lower stacking beams. The upper stacking beam (1) is arranged on the lower stacking beam (2), two left connecting frames are fixedly arranged at the left end of the upper stacking beam (1), and two right connecting frames are fixedly arranged at the right end of the upper stacking beam (1) , the other end of the left front frame beam (5) is hinged with the other end of the right front frame beam (6) through the top connecting pin (9), and the upper end of the front boom (10) is connected to the front end of the top connecting pin (9) , the upper end of the rear boom (17) is connected to the rear end of the top connecting pin (9), and a horizontal support beam (11) is connected between the front boom (10) and the rear boom (17). A jack (18) is arranged on the beam (11), and the upper end of the jack (18) is connected to the lower bottom surface of the lower stacking beam (2). The invention ensures the overall quality of boiler installation.

Description

technical field [0001] The invention relates to an installation device for a boiler bearing beam in a power plant, in particular to an installation device for a boiler bearing stack beam in a power plant. Background technique [0002] With the increase of the unit capacity of the thermal power plant, the overall weight and structural size of the boiler are also increasing. In order to meet the requirements of span and load bearing, the design size and weight of the steel structure large plate beam carrying the boiler are also constantly increasing. to increase. At present, the weight of a single piece of steel structure slab girder has reached more than 150 tons, but limited by the transportation capacity of the transportation equipment, the heavy slab girder is generally designed as a type of upper and lower stacked beams, and the manufacturer divides the large slab girder into The upper and lower floors are manufactured separately and transported to the site separately fo...
