High-safety tower crane for building structure construction

Abstract

The invention discloses a high-safety tower crane for building structure construction and relates to the technical field of tower cranes for construction. The high-safety tower crane for building structure construction comprises a base, a frame body, standard joints, a boom and a balance arm. A sleeve frame platform is fixedly connected with the upper portion of the frame body and located on the outer wall of the corresponding standard joint. The bottom of the balance arm is fixedly connected with a cab. The top of the frame body is fixedly connected with a tower cap. A boom tie rod is fixedlyconnected between the tower cap and the boom. A boom auxiliary tie rod is fixedly connected between the tower cap and the boom and located on the inner side of the boom tie rod. An amplitude changingtrolley is connected with the bottom of the boom in a sliding manner. The high-safety tower crane for building structure construction achieves the purpose that the frame body composed of the standardjoints is more stable, and the standard joints are installed in a penetrated manner and fixed through bolts, so that the stability is guaranteed after the frame body is assembled; and each standard joint and the corresponding lower standard joint are connected through insertion plates and insertion grooves, so that the connected standard joints can bear force in more directions, connection is firmer and tight, and therefore the safety of tower crane operation personnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tower cranes for construction, in particular to a tower crane for building structure construction with high safety performance. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". Raw materials for construction such as steel pipes. The tower crane is an indispensable equipment on the construction site. The tower cranes in the prior art generally rely on the bottom of the tower crane to be fixed to the ground to achieve load bearing, or rely on the building to complete the load bearing, but the standard section is the most numerous part of the tower crane. It needs to bear the working load, as well as the self-load and wind load of the upper part of the tower crane, and also support the normal operation of the components carried on the tower crane. The adjacent parts are only fixed by high-strength bolts. If the construc...
