Digital and intelligent lifting control device

Abstract

The invention discloses a digital and intelligent lifting control device, which is characterized by comprising a PLC (Programmable Logic Controller) and a control panel electrically connected with the PLC, wherein the PLC is connected with multiple groups of lifting devices, and each group of lifting devices is provided with a revolution speed transducer connected with the PLC. The digital and intelligent lifting control device has the advantages of whole or partial synchronous rising and descending function to a scaffold, overload protection, emergency stopping and early warning function to failure; and a rising or descending height can be preset, when being wholly lifted to operate to reach the preset height, the scaffold can be automatically in place and meet a horizontal requirement, and thereby ensuring synchronism and safety when the scaffold is wholly lifted to rise and descend, and ensuring the safety of lives and properties of on-site personnel; and heavy leveling operation caused by wholly lifting the scaffold by the conventional lifting equipment is completely removed, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to a digital intelligent lifting control device, which is suitable for overall lifting scaffolding in the construction of high-rise building main bodies and decoration projects, and is also suitable for multi-point synchronous horizontal and stable hoisting and installation of extra-large components and equipment in other projects. Background technique [0002] At present, the lifting devices of scaffolding include: manual hoist, electric hoist, special hoist, core-piercing hydraulic jack, etc. Among them, the electric hoist is used in a large amount. Although the electric hoist can meet the overall safety of the scaffold, most of the previous control methods use high-power contactors to connect all the lifting motors at the same time to achieve the purpose of synchronization, but it is difficult to achieve synchronization in the true sense. And smooth lifting, it has the following problems: because the lifting speed of the liftin...

Problems solved by technology

Among them, the electric hoist is used in a large amount. Although the electric hoist can meet the overall safety of the scaffold, most of the previous control methods use high-power contactors to connect all the lifting motors at the same time to achieve the purpose of synchronization, but it is difficult to achieve synchronization in the true sense. And smooth lifting, it has the following problems: because the lifting speed of the lifting motor is affected by the load of the scaffold, and the scaffold cannot be a uniform load, so such synchronization is actually not true synchronization; although the contactor is connected to the lifting motor at the same time, but The actual response time of the lifting motor is not consistent and other factors will also affect the realization of synchronization
