Tower crane lifting device

Abstract

The invention provides a tower crane lifting device, and relates to the technical field of engineering machinery. The tower crane lifting device comprises a base, a sliding limiting mechanism is fixedly connected to the top of the base, a lifting joint is slidably connected to the center of the sliding limiting mechanism, and a lifting jacking mechanism corresponding to the lifting joint is arranged in the center of the base. A plurality of fixed-point locking mechanisms corresponding to the lifting joint are installed on the outer side of the sliding limiting mechanism, and the bottom of one side of the sliding limiting mechanism is fixedly connected with a sliding guide mechanism corresponding to the lifting joint. A mounting groove corresponding to the lifting jacking mechanism is formed in the center of the base. Through the sliding limiting mechanism, the lifting jacking mechanism, the fixed-point locking mechanism and the sliding guide mechanism which are simple in design, a standard knot can be quickly assembled and fixed at the bottom of a tower crane, operation is convenient, meanwhile, no large construction risk exists, and the device is worthy of vigorous popularization.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a tower crane lifting device. Background technique [0002] Tower crane, short for "tower crane", also known as "tower crane"; is a kind of lifting equipment used in building construction. Industry classification and attribution: machinery->construction machinery->hoisting machinery->construction hoisting machinery->tower crane, the tower crane needs a basic part to be installed on the ground; the tower body is the body of the tower body, which is also a raised part; the top The lifting part is to make the tower crane rise; the slewing is to keep the upper body of the tower crane to rotate horizontally; the hoisting mechanism is used to lift the heavy objects; The force-bearing part of the object; the trolley is used to install the pulley block, the steel rope and the hook, and it is also the direct force-bearing part; the top of the tower is of course ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a tower crane lifting device, which solves the problem that the traditional tower crane lifting devices all adopt follow-up structure design, although normal lifting operations can be performed, but for small tower cranes and low-height The tower crane construction adopts the follow-up lifting device, which is not convenient for operation, but also easily causes waste of construction time, and does not take advantage of the problem of reducing the risk of high-altitude construction
