Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the prior art, when the decoration platform is installed on the lower side of the TV tower component shield, when the tower crane lifts the middle part of the platform truss close to the tower, the platform truss will be blocked by the tower component barrier. There is a certain distance between the front end of the tower and the part where the tower needs to be installed, so that the platform truss cannot be installed directly, and the platform truss needs to be pulled closer manually with a hand chain hoist, and the installation operator is suspended in the air. link fit and lower

Embodiment 1

[0032] Such as Figures 2 to 4 As shown, the balance beam of the hoisting platform truss in this embodiment is a kind of single-side hoisting equipment, which is made to make the long and thin member of the cantilevered construction platform truss of the TV tower tower, such as the platform scale, and keep the member in a horizontal state during the hoisting process. . The balance beam of the hoisting platform truss includes a main beam 1 , an operating platform 2 and a counterweight frame 3 , and the main beam 1 may be a round tube main beam or a square tube main beam. The operating platform 2 is used as a high-altitude hoisting operator to dismantle the balance beam and the truss binding rope. The operating platform 2 is located above the front of the main beam 1. The operating platform 2 can be a slab platform. A fence 6 is arranged around the operating platform 2 to protect the personal safety of operators. The main beam 1 is provided with hoisting lugs 4 for hoisting, a...

Embodiment 2

[0040] Such as Figures 5 to 7 As shown, the balance beam of the hoisting platform truss in this embodiment includes a main beam 1 , an operating platform 2 and a counterweight frame 3 , and the main beam 1 can be a round tube main beam or a square tube main beam. The operating platform 2 is a slab platform, located above the front of the main beam 1, and fences are arranged around the operating platform 2, so that it can be used as a high-altitude hoisting operator to dismantle the balance beam and the truss binding rope.

[0041] The main girder 1 is provided with hoisting lugs 4, and there are three hoisting lugs 4, which are evenly distributed and welded on the main girder 1 between the operation platform and the counterweight frame. The counterweight weight of the counterweight frame 3 is calculated and configured according to the hoisting eccentric moment of the platform truss 9 and the main beam 1 of the hoisting member, and can be adjusted according to the weight of th...

Abstract

The invention discloses a balance beam for lifting a platform truss and a lifting method thereof. The balance beam comprises a main beam (1), an operation platform (2) and a counterbalanced carriage (3), wherein the operation platform (2) is arranged above the main beam (1); the counterbalanced carriage (3) is hung on the main beam (1); and lifting lug plates (4) are arranged on the main beam. The platform truss can be lifted at one side; and the platform truss is adjusted to a horizontal state by using the main beam and a counterweight, and then is lifted. In the lifting, the platform truss is not blocked by a tower component blocking object, and can be directly mounted at the part, needed to be mounted, of a tower without needing operators to perform suspended operation, so that the safety of working at heights is improved, and the mounting efficiency is enhanced; the lifting method is safe and efficient; meanwhile, for components originally mounted from bottom to top in sequence, upper components can be mounted firstly when a perfecting scheme is not made for lower attachments or measures; and then the lifting of lower blocked components is performed by using the lifting method, so that the construction period is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to a balance beam for building construction, in particular to a balance beam for hoisting platform trusses. Background technique [0002] In the construction of the TV tower, after the tower structure (over 100 meters above the sky) is installed, it is necessary to install a decoration platform on the lower side of the tower component shield, such as figure 1 As shown, the original installation method needs to hang the inverted chain on the lower side of the shelter, or use the hoist to convert the hoisting equipment to the guide pulley for relay hoisting. The tower crane hoisting point is the stress point of the platform truss 9 located on the platform In the middle of 9, when the platform truss 9 is hoisted by the tower crane hook 7 and approaches the tower, the front end of the platform truss 9 is at a certain distance from the position where the tower needs to be installed due to the obstruction of the tower components, so tha...
