Abstract
The utility model belongs to the technical field of overload control of a speed-adjusting controller and a special frequency converter for a crane, in particular to a speed-adjusting controller with a weight control function for a crane. The speed-adjusting controller is composed of a weight sensor, an input circuit, a data processor, a display, a controller and a power unit, wherein, the data processor is a microprocessor, and the full-range output voltage of the weight sensor is 1V. The the speed-adjusting controller has the following main technical characteristics: a special weight sensor interface is designed in the crane controller, and used for displaying the measured value of the lifting weight in real time; when the lifting weight exceeds 105% of the rated weight of the crane, the crane controller gives an alarm immediately so as to maintain a brake in a braking condition; and when the lifting weight is reduced to below 105% of the load weight of the crane, the crane recovers an operating mode. The crane can monitor the lifting weight in real time so as to ensure safety operation of the crane; and speed adjustment of the crane is realized by changing the output voltage.
Description
Technical field
The utility model belongs to hoisting crane with speed setting controller, lifting special converter overload control technology field, particularly relates to a kind of hoisting crane speed setting controller with hoisting crane weight control.
Background technology
Present existing crane controller does not all have the input interface of weight sensor.In the crane operation process, lifting weight is not monitored in real time.In a single day occur clamping stagnation or other accidents in the lifting process and cause that the moment overload will produce influence greatly to the safe operation of weight-lifting equipment and the life-span of equipment; if there is a kind of control setup to carry out monitoring in real time to the whether overload in the hoisting crane work process, will satisfy greatly " elevator machinery overload protection device technical specification of security " (GB12602-1990) in control requirement of regulation.
Summary of the invention
The purpose of this utility model is to provide a kind of lifting weight that can monitor in real time in the hoisting crane work process, guarantees the hoisting crane speed setting controller with hoisting crane weight control of the safe operation of hoisting crane.
The purpose of this utility model is achieved through the following technical solutions.
Hoisting crane speed setting controller with hoisting crane weight control of the present utility model, it is characterized in that by weight sensor, the input circuit that is connected of weight sensor therewith, the data handler that is connected of input circuit therewith, the telltale, the controller that are connected of data handler therewith respectively, the power cell that is connected of controller is formed therewith.This power cell is the main road device.
Described data handler is a microprocessor.
The full scale output voltage of described weight sensor is 1V.
Major technique of the present utility model is characterized as weight sensor Interface design with special use in crane controller, and lifting weight shown observed reading in real time, when lifting weight surpass the hoisting crane rated weight 105% the time, crane controller is reported to the police immediately, make damper brake be in braking mode, hoisting crane quits work.When weight is reduced to crane rating 105% when following, the hoisting crane state of just can resuming work.
The full scale formula output voltage of weight sensor is 1V.Its output directly is connected with the corresponding interface of the present utility model.Signal is delivered to microprocessor of the present utility model after the input circuit pre-process, data analysis is delivered to the display part after handling.The crane operation personnel can observe liter weight at any time.Realize the hoisting crane speed governing by changing output voltage.
According to " elevator machinery overload protection device technical specification of security " (GB12602-1990) in regulation, when rise liter weight surpass the hoisting crane rated weight 105% the time, system sends the overload signal, and makes the damper brake braking.
The beneficial effects of the utility model are: can monitor the lifting weight in the hoisting crane work process in real time, guarantee the safe operation of hoisting crane.
