Problems solved by technology

[0002] The tower crane on the construction site is an indispensable tool for vertical transportation, but because the spreader and the hoist are easy to swing, this not only prolongs the unloading work cycle, but even causes accidents due to decoupling in serious cases. Currently, the anti-sway cranes on the market There are still relatively few devices, and the technology is not mature enough. In order to overcome the above problems, the present invention provides an anti-sway control device for construction tower cranes

Abstract

A building tower type crane anti-swing device is an indispensable tool for vertical transportation. Due to the fact that a lifting tool and a lifting load are likely to swing, the unloading work period is prolonged, even unhooking happens and serious accidents are caused. The building tower type crane anti-swing device comprises a main machine, a three-axis accelerometer, a photoelectric encoder I, a photoelectric encoder II, a rotary frequency converter, a trolley frequency converter, a rotary motor, a trolley motor, a rotary mechanism and a wireless communication device. The building tower type crane anti-swing device is characterized in that the main machine is connected with the photoelectric encoder I and the photoelectric encoder II; the photoelectric encoder I is connected with the rotary frequency converter; the photoelectric encoder II is connected with the trolley frequency converter; and the rotary frequency converter is connected with the rotary motor, and the trolley frequency converter is connected with the trolley motor.

Description

technical field [0001] The invention relates to the design field of tower cranes, in particular to an anti-sway device for construction tower cranes. Background technique [0002] The tower crane on the construction site is an indispensable tool for vertical transportation, but because the spreader and the hoist are easy to swing, this not only prolongs the unloading work cycle, but even causes accidents due to decoupling in severe cases. Currently, anti-sway cranes on the market There are still relatively few devices, and the technology is not yet mature. In order to overcome the above problems, the present invention provides an anti-sway control device for a construction tower crane. Contents of the invention [0003] In order to solve the above problems, the present invention designs an anti-sway device for a construction tower crane. [0004] The technical scheme that the present invention solves the problem is: [0005] An anti-sway device for a building tower crane...
