Abstract
The utility model discloses a circuit control system for a construction hoist, which comprises a lifting electric motor, an electromagnetic brake, a weight limiting sensor, a control button and a PLC (Programmable Logic Controller). The control button is connected with the input end of the PLC; the output end of the PLC is respectively connected with the electromagnetic brake, the lifting electric motor and the weight limiting sensor; the impact vibration, shake and noise of the hoist are reduced; and the construction hoist operates stably and comfortably.
Description
Technical field
The utility model relates to the building hoist technical field, relates in particular to a kind of building hoist circuit control system.
Background technology
Building hoist is that a kind of traditional dual-purpose vertical lifting equipment of people, goods is widely used.The building hoist of prior art exists the some shortcomings part; As: when upwards promoting,, cause driver train and cage by gravity to produce the moment downslide because electrical motor and electromagnetic braking are moved simultaneously; Cause building hoist to vibrate, impact, and starting current is big; Rise when stopping, not impacting, produce vibration, noise because the inertia that driver element cage and carrier produce when rising disappears; When the bigger decline of load stopped, the inertia that driver element and cage produce when descending caused gliding bigger.More than three kinds of operating modes are technical barriers that traditional building hoist production firm and professional and complete producer are difficult to capture for many years; Many experts of the same trade for many years, technical personnel were also done many trials and checking in this respect, but finally obtained satisfactory effect.
Summary of the invention
The purpose of the utility model is exactly to start in order to solve traditional building hoist that prior art exists that to stop operating mode transient vibration, impact, noise big, the operate steadily problem of traveling comfort difference of complete machine; A kind of building hoist circuit control system is provided; The impact shock that has reduced elevator with rock, noise, make building hoist operate steadily, comfortable.
To achieve these goals, the utility model adopts following technical scheme:
The building hoist circuit control system comprises the electrical motor that hoists, magnet stopper, weight limits sensor; Control button, PLC (programmable controller), control button is connected with the input end of PLC; The mouth of PLC respectively with magnet stopper, the electrical motor that hoists, the weight limits sensor connects.
The principle of work of the utility model: the utility model comprises PLC, the electrical motor that hoists, magnet stopper; The weight limits sensor, control button, control button is connected with the input end of PLC; The mouth of PLC respectively with magnet stopper; The electrical motor that hoists, the weight limits sensor connects, and the weight limits sensor is installed in driver element and cage junction.When upwards promoting, through the control of delaying time of programmable controller PLC system, the electrical motor that hoists starts earlier, and magnet stopper is opened again, reached starting steadily, has overcome mechanism, cage and has carried weight deadweight effect and produce the problem that moment glides down.Rise when stopping operating mode, the control of programmable controller PLC system delay, the electrical motor that hoists at first cuts off the power supply; Magnet stopper action then, braking again after the inertia that produces when the cage carrier rises disappears has slowed down this operating mode greatly and has impacted and generation of noise; From another perspective; The reducing of impulsive force improved the stressed working condition of reductor, tooth bar, guide rail bracket greatly, can effectively carry the service life that prolongs mechanism's parts, the fatigue of slowing down steel construction piece.When the bigger decline of load stops, analyzing the weight limits sensor signal automatically through programmable controller PLC system, the control of delaying time; Cutting off the magnet stopper power supply earlier realizes slowing down; The electrical motor that hoists subsequently outage realizes stopping action, can effectively reduce downslide amount, reduces impact shock.
The beneficial effect of the utility model: the programmable control system that uses the utility model to building hoist rise start, rising stops, descending stops to control; Make building hoist operate steadily, comfortable, the impact shock that has reduced elevator with rock, noise.
Description of drawings
Fig. 1 is the electrical block diagram of the utility model;
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
