Abstract

The invention discloses a mounting device for laminated beams of a main girder, and solves the technical problem of clearance leakage in connection of upper and lower laminated beams, which possibly causes joint gaping on the upper and the lower laminated beams. The mounting device comprises an upper laminated beam (1) arranged on a lower laminated beam (2), two left connecting frames are fixedly arranged at the left end of the upper laminated beam (1), two right connecting frames are fixedly arranged at the right end of the upper laminated beam (1), the other end of a left front frame girder (5) and the other end of a right front frame girder (6) are hinged together through a top connecting pin (9), the upper end of a front suspender (10) is connected to the front end of the top connecting pin (9), the upper end of a rear suspender (17) is connected to the rear end of the top connecting pin (9), a horizontal supporting beam (11) is connected between the front suspender (10) and the rear suspender (17), a jack (18) is arranged on the horizontal supporting beam (11), and the upper end of the jack (18) is connected to the lower bottom surface of the lower laminated beam (2) in a propping manner. The mounting device provided by the invention ensures entire 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...
