Abstract

The invention discloses a tower crane experiment platform which comprises a tower arm, a tower body, a hoisting structure and a driving mechanism, the tower arm and the tower body form a T-shaped tower crane main body structure, the hoisting structure is arranged at the front end of the tower arm, a light hanging rod is arranged below the hoisting structure, and the hoisting structure can rotate the light hanging rod to swing in two directions; the light suspender penetrates through the hoisting structure and can ascend and descend along the hoisting structure; a lifting object is arranged at the bottom of the light lifting rod; a balancing weight is arranged at the tail part of the tower arm so as to ensure the balance of the tower arm; the driving mechanism comprises main driving equipment arranged on the tower arm, and the main driving equipment drives the hoisting mechanism to move along the tower arm and drives the tower arm and the balancing weight and the hoisting structure on the tower arm to rotate relative to the tower body. Experiment cost can be reduced, certain dangerousness is reduced, manpower is saved, climbing of the tower crane back and forth is reduced, and safety and convenience are achieved.

Description

technical field [0001] The invention belongs to the technical field of tower cranes, and in particular relates to a tower crane experiment platform. Background technique [0002] With the advancement of technology, the luffing mechanism, luffing trolley, and automatic magnification device of the horizontal arm tower crane are continuously optimized to improve performance and efficiency. For the luffing mechanism, luffing trolley, and crane of the tower crane Hook group performance, service life and other parameters were basically tested on the whole machine in the past, and the time and effect could not be guaranteed. Therefore, it is necessary to develop a reliable and specialized test and detection device, which is very important for the design verification of new components. Because the experiment of outdoor tower crane is both dangerous and costly, an experimental platform that can reproduce the functions of tower crane lifting, luffing and slewing is needed.
