Description
Technical field
The utility model relates to a kind of hoisting capacity slicer, belongs to crane safety protection field, is specifically related to a kind of pre-deceleration hoisting capacity slicer.
Background technology
Hoisting capacity slicer is hoisting machinery safeguard protection device, it is specifically designed to the electric block list two-beam type lifting machine of various model specification, this device has acoustic alarm, reports to the police immediately, cuts off crane hoisting electric motor loop and the display function such as hoisting heavy weight, can avoid equipment that weight handling equipment causes because of overload overload and fatal accident; When lifting machine lifts by crane the lifting thing of large-scale lifting thing or heavyweight, if lifting thing is lifted to specified location and again lifting motor is carried out power-off operation, it is easy to hoisting drum and lifting motor are caused damage, and moment is out of service, lifting thing will obtain very big inertia, is easy to lifting rope is caused damage, and the number of times used along with lifting machine increases, probably there is the situation of lifting rope fracture, thus cause security incident.
Summary of the invention
The utility model provides a kind of safe and reliable, systematize, intelligentized pre-deceleration hoisting capacity slicer for overcoming the deficiencies in the prior art.
The technical solution of the utility model is: a kind of pre-deceleration hoisting capacity slicer, it comprises crane control panel, PLC and lifting mechanism, being provided with input end station, display terminal and alarm unit on described crane control panel, described PLC is arranged in crane control panel; Described lifting mechanism comprises crampoons, lifting motor and hoisting drum, and described crampoons is provided with rang sensor, and described lifting motor is provided with stopper A, and described hoisting drum is provided with stopper B and hoisting capacity slicer.
Described PLC is connected with input end station, display terminal, alarm unit by signal wire.
Described input end station keypad.
Described PLC is connected with rang sensor and hoisting capacity slicer by signal wire.
Described PLC is connected with stopper A and stopper B by control signal line.
The beneficial effects of the utility model are: the utility model realizes like this, and operator sets the lifting operating parameter of lifting machine by input end station, the upper limit of setting slinging matter weight;The utility model arranges the tolerance range that hoisting capacity slicer effectively improves hoisting capacity of the present utility model restriction at hoisting drum place, effectively prevents the utility model from overweight operation occurring; The carrying out of lifting thing is detected by hoisting capacity slicer of the present utility model in real time, and detected result is fed back in real time PLC, the upper limit of the data of Real-Time Monitoring and setting is vertically contrasted by PLC, if the weight of lifting thing exceedes the upper weight limit of the lifting thing of setting, PLC sends the signal of warning to alarm unit, drive stopper A and stopper B simultaneously, stop the operation of hoisting drum and lifting motor; The rang sensor Real-Time Monitoring suspension hook that this practicality is arranged on crampoons is to the distance on ground, and vertically feed back to PLC by what detect, the safe distance that PLC sets according to operator numerical value, when crampoons moves to the safe distance of setting time, PLC sends the signal of brake deceleration operation to stopper A, controller B and lifting motor, lifting motor and hoisting drum constantly slowly run slowly, until crampoons arrives the lifting height specified, lifting motor and hoisting drum are out of service; The utility model has safe and reliable, systematize, intelligentized advantage.
