Abstract

The invention discloses an embedded bolt type foundation section of a tower crane. The embedded bolt type foundation section comprises two bases, a connecting mechanism and a protection mechanism. Ribplates are arranged at the top ends of the two bases, main chord members are installed on the inner walls of the rib plates, web members are fixedly connected to one side of one main chord member andone side of the other main chord member, and a step is mounted on one side of one main chord member. By arranging the connecting mechanism, when the tower crane structure is connected, standard joints are moved to a proper position through the crane, connecting rods are inserted into grooves matched with second connecting pieces, convex blocks are extruded under the action of abutting plates, andsprings are compressed under the action of stress; and when the standard joints are adjusted to the proper position, the convex blocks are clamped into grooves matched with one sides of spring grooves so as to limit and fix the grooves, meanwhile, fixed rods are inserted into limiting openings so as to assist in positioning, and rapid butt joint is facilitated.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to a pre-embedded bolt-type foundation section of a tower crane. Background technique [0002] Tower crane, also known as "tower crane", is a kind of heavy lifting equipment used for construction. The tower crane is assembled from multiple structures. The firmness and stability of the tower crane connection structure have become an important performance index of the tower crane. Existing tower cranes generally use a fixed-leg foundation or a well-shaped underframe foundation. The fixed-leg foundation pre-buries the fixed legs into the reinforced concrete foundation and is directly connected to the tower body of the tower crane. Use, the cost is higher. In order to solve this problem, patent CN205772960U discloses a tower crane pre-embedded bolt type foundation section, which directly connects the tower crane foundation section with the pre-embedded anchor bolts in the concrete foundatio...
