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
The present invention relates to a kind of digital intelligent and promote control device, the integral hoisting scaffold that it is applicable in highrise building main body and the decorative engineering construction operation also is suitable for the steadily lifting installation in place of especially big member in other engineering, equipment multiple spot level of synchronization.
Background technology
The lifting gear of scaffold has at present: bottle gouard moved by hands, electric block, special-purpose hoist engine, punching hydraulic jack etc.Wherein large usage quantity is electric block; Though electric block can satisfy the Degree of Safety of scaffold; The high-power contactor of the most employing of control method is in the past connected whole lifting motors simultaneously and is reached synchronous purpose, but is difficult to reach synchronous and steady up-down truly, and there is following problem in it: because the hoisting velocity of lifting motor receives the scaffold effects of load; And scaffold can not be uniform load, therefore so synchronous reality be not real synchronously; Though contactor is connected lifting motor simultaneously, the actual response time of lifting motor and factor such as inconsistent also can influence synchronous realization.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide a kind of digital intelligent and promote control device; This device can be realized detecting automatically to the instantaneous up-down situation of each machine of many suspension centres, the automatic digital intelligent control of feeding back, handling automatically; Guarantee the synchronization lifting that multimachine is real; Thoroughly get rid of the asynchronous heavy leveling operation of bringing for integral hoisting scaffold of lifting means in the past, realize need not any leveling, the intelligent synchronization control of real meaning.
The technical scheme that the present invention adopts is:
A kind of digital intelligent promotes control device; Comprise PLC controller and the control panel that is electrically connected with the PLC controller; Be connected with many group lifting gears on the said PLC controller, be provided with the speed probe that is connected with the PLC controller on said every group of lifting gear; Said lifting gear comprises lifting motor, the thermal relay that links to each other with lifting motor successively, contactor and drive circuit, and said drive circuit is electrically connected with the PLC controller; Said speed probe is used to receive the actuating signal of the measure speed gears in the lifting motor.
The present invention utilizes speed probe to receive the measure speed gears transmission number of teeth signal of lifting motor; And with number of teeth signal feedback to the PLC controller; The PLC controller carries out computing, dynamic real-time monitor to number of teeth signal, in lifting process, each seat in the plane is realized control automatically and is detected automatically, carries out the dynamic real-time adjustment; Guarantee that the difference in height of going up and down in each seat in the plane is controlled in safe, the controlled scope, reaches the purpose of synchronization lifting.
The present invention has scaffold synchronization lifting function in whole or in part; Overload protection, stop in emergency, the fault pre-alarming function; And rising or falling head can be set in advance, and when the integral hoisting scaffold operation reaches the height that is provided with in advance, the autofitting and the requirement that is up to the standard; Guarantee synchronism and safety that integral hoisting scaffold is gone up and down, guaranteed the safety of Field Force life, property; Thoroughly get rid of the heavy leveling operation that lifting means in the past brings for integral hoisting scaffold, enhance productivity.

The specific embodiment
As shown in Figure 1; A kind of digital intelligent promotes control device; Comprise PLC controller 1 and the control panel 2 that is electrically connected with PLC controller 1; On PLC controller 1, be connected with many group lifting gears 3, every group of lifting gear 3 includes lifting motor 4, the thermal relay 5 that links to each other with lifting motor 4 successively, contactor 6 and drive circuit 7, and drive circuit 7 is connected with PLC controller 1; On every lifting motor 4, be provided with the speed probe 9 that is connected with PLC controller 1, speed probe 9 is used to receive the actuating signal of the measure speed gears 8 in the lifting motor 4.
The present invention is running like this: through control panel 2 setting values, control panel 2 sends instruction and gives PLC controller 1, through control drive circuit 7 after 1 computing of PLC controller, drives lifting motor 4 work through contactor 6, thermal relay 5.During lifting motor 4 work; Must drive measure speed gears 8 rotates; Speed probe 9 feeds back to PLC controller 1 with the RST of measure speed gears 8, and the sensor signal of 1 pair of input of PLC controller is carried out computing, dynamic real-time monitor, in lifting process, each seat in the plane is realized detecting automatically and control automatically; Carry out the dynamic real-time adjustment; Guarantee that the difference in height gone up and down in each seat in the plane is controlled in safety, the controlled scope, behind the adjustable height that arrives control panel 2 instructions, adjustment is in place automatically for PLC controller 1 control drive circuit 7 instruction lifting motors 4; This device is desirable integral-scaffold synchronization lifting control device.
