Dislocation assembly network frame hoisting construction method and its hoisting system

Abstract

The invention discloses a hoisting construction method of assembling a net frame in a dislocation way as well as a hoisting system. The hoisting construction method comprises the following steps: the specification and the quantity of gin poles are chosen, a pole base is positioned on a steel plate, and a displacement traveling device is arranged at the bottoms of the gin poles; a hoisting mechanism is installed; connecting cords are connected among the top parts of the gin poles in a penetrating way, and the connecting cords are connected with an adjusting chain hoist at the bottoms of the gin poles; foot enclosing cords are arranged on the gin poles and connected with a ground anchor through the chain hoist; and hauling cords are arranged at the top parts of the gin poles and are connected with a winch through a ground anchor pulley block. The winch is started up to hoist the net frame to the preset height and to be locked. When the displacement traveling device arranged at the bottoms of the gin poles is started to realize the displacement of bottoms of the gin poles, simultaneously the hauling cords are adjusted to realize the displacement of the top parts of the gin poles and the horizontal movement of the gin poles under the vertical state so as to drive the net frame to move. After the net frame is horizontally moved in place, the net frame falls back onto the supports at the top parts of the gin poles by utilizing the returning of the winch. The invention ensures that the gin poles are horizontally moved under the vertical and balance states to drive the net frame to the preset position, so the excessive stress condition of the gin poles is avoided.

Description

technical field [0001] The invention relates to a hoisting construction method and a hoisting system of a dislocation assembled grid frame. Background technique [0002] It is much more convenient to assemble the grid structure on the ground than at high altitude, and it is more beneficial to ensure the quality of the project. Moreover, for the rectangular grid frame with better rigidity and larger span, when it must be dislocated and assembled due to obstacles, it needs to be hoisted and translated to the predetermined position through the combination of multiple poles. In the prior art, the translation process of the network frame is to complete the aerial displacement of the network frame by tilting the pole until the network frame is aligned with the top of the column. Since the weight of the grid structure is relatively large and the hoisting height is relatively high, the aforementioned method of moving the grid structure by tilting and unbalancing the pole will make ...

Problems solved by technology

Due to the relatively large weight of the grid structure and the relatively high hoisting height, the aforementioned method of moving the grid frame by tilting and unbalanced poles will make the force on the poles worse.
