Abstract
The invention discloses an intelligent scaffold anti-falling electric wave interference preventing method. An intelligent scaffold control system is used for controlling ascending and descending of a scaffold. Gear mechanisms are driven to rotate through lifting motors, rotating speed sensors send out rotating speed pulses, collecting counters collect pulse signals, count the pulse signals and send the pulse signals to a PLC, the PLC converts the pulse number into ascending and descending heights according to set coefficients after receiving the pulse number, compares the ascending and descending heights with the set heights, and automatically controls the lifting motors at corresponding positions to stop after the set heights are reached. In the ascending and descending process, the PLC compares the heights of all positions, calculates the ascending and descending height differences among the positions and controls the operation state of the lifting motor at the position with the largest difference when the maximum difference exceeds the allowable value to achieve the synchronous ascending and descending at all the positions. The PLC controls an anti-falling device to act. According to the intelligent scaffold anti-falling electric wave interference preventing method, operation is convenient, work is safe, and controllability is good.
Description
Technical field
The present invention relates to a kind of anti-fall anti-wave interference method of scaffold.
Background technology
The elevating control of scaffold is the problem that this area needs to solve always, exists for a long time and controls easily to occur the problems such as adjustable height difference between instability, each seat in the plane.
Summary of the invention
The anti-fall anti-wave interference method of the Intelligent foot hand cradle that the object of the present invention is to provide a kind of control performance good.
Technical solution of the present invention is:
A kind of anti-fall anti-wave interference method of Intelligent foot hand cradle, is characterized in that: the lifting adopting scaffold intelligent control system control pin hand cradle; Described scaffold intelligent control system comprises the lifting motor of each seat in the plane, lifting motor is connected with drive circuit by thermal relay, contactor, drive circuit is connected with PLC, PLC is connected with speed probe, and speed probe is the sensor measuring the travelling gear rotating speed that lifting motor drives; PLC is connected with control panel; Lifting motor driven gear mechanism rotates, speed probe sends tacho-pulse, acquisition counter device collects this pulse signal, count and send PLC to, after PLC receives umber of pulse, according to the coefficient of setting, convert umber of pulse to adjustable height, and compare with setting height, after reaching setting height, automatically control this seat in the plane lifting motor stop; In lifting process, the height of PLC to each seat in the plane compares, and calculates the adjustable height difference between each seat in the plane, when maximum difference exceeds permissible value, PLC controls the seat in the plane lifting motor running status of maximum difference, realizes synchronization lifting between each seat in the plane; PLC controls the action of falling proof device.
The present invention is easy to operate, and work safety, control performance are good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the Control system architecture schematic diagram of one embodiment of the invention.
Detailed description of the invention
A kind of Intelligent foot hand cradle anti-fall (simultaneously can comprise anti-wave interference) method, adopts the lifting of scaffold intelligent control system control pin hand cradle; Described scaffold intelligent control system comprises the lifting motor 1 of each seat in the plane, lifting motor is connected with drive circuit 4 by thermal relay 2, contactor 3, drive circuit is connected with PLC 5, PLC is connected with speed probe 6, and speed probe is the sensor measuring the travelling gear rotating speed that lifting motor drives; PLC is connected with control panel 7; Lifting motor driven gear mechanism 8 rotates, speed probe sends tacho-pulse, acquisition counter device collects this pulse signal, count and send PLC to, after PLC receives umber of pulse, according to the coefficient of setting, convert umber of pulse to adjustable height, and compare with setting height, after reaching setting height, automatically control this seat in the plane lifting motor stop; In lifting process, the height of PLC to each seat in the plane compares, and calculates the adjustable height difference between each seat in the plane, when maximum difference exceeds permissible value, PLC controls the seat in the plane lifting motor running status of maximum difference, realizes synchronization lifting between each seat in the plane; PLC controls the action of falling proof device.
