Description
Technical field
The utility model relates to a kind of single (two) girder steel driving hoisting capacity overload protection device, belongs to elevator machinery security protection technology field.
Background technology
Single (two) girder steel driving weight-lifting equipment is generally arranged in plant building; often have behaviour people workman in work below driving weight-lifting equipment, the overload protection of girder steel driving hoisting capacity is most important for the safety of workers ensured under service life of equipment and support equipment.The consequence of overload also can cause the tragedy of car crash.In order to ensure the safety of elevator machinery, country has promulgated " GB6067-85 safety rules for lifting appliances " and " GB/T3811-2008 elevator machinery design regulation ".
Summary of the invention
A kind of girder steel driving of the utility model hoisting capacity overload protection device object is; lifting scope is allowed in order to avoid girder steel driving operation exceeds it; allow driving can safety, run and ensure property life security efficiently, the utility model proposes a kind of girder steel and to drive a vehicle hoisting capacity overload protection device.
The technical solution of the utility model is, a kind of girder steel driving of the utility model hoisting capacity overload protection device is made up of main frame instrument box, sensor and transfer box; Sensor is arranged between bearing seat and base, and sensor connects transfer box by signal wire (SW); Transfer box connects the circuit module of main frame instrument box by shielded cable; Main frame instrument box is installed on inside driver driving room, and keep instrument to install robust, driver can clear visual instrument display panel.
Main frame instrument is made up of signal acquisition module, signal processing module, display unit, memory storage and control output module.The mechanical quantity received is transformed into electric signal and delivers to signal acquisition module by weight sensor; Signal acquisition module converts analog quantity to digital quantity and send signal processing module, by CPU process; Result send display unit show and send control output module by signal processing module respectively, is undertaken controlling whether to cut off circuit, carry out overload protection and send overload alerting signal by control output module.
The utility model girder steel driving hoisting capacity overload protection device has maximum 4 road acquisition of signals, and 8 controlling points, tunnel export.
The utility model list (two) girder steel driving hoisting capacity overload protection Real-time Collection driving weight signal, when weight reaches driving rated load weight 90%, sends interrupted acousto-optic chimes of doom, reminds driver to take care.When weight reaches driving rated load weight 105%, send continuous sound and light alarm sound, and provide rising ct-off signal.Now driving only supports decline operation, does not support rising operation.Now gauge internal black box module record overload operation.Thus ensure the safe operation of driving.
The beneficial effects of the utility model are, the utility model, by gathering driving weight signal, when weight exceedes certain limit, sends alerting signal and ct-off signal, ensure that the safe operation of driving.The utility model possesses the functions such as numerical monitor hoisting capacity, overload early warning, overload control, is widely used in the weight-lifting equipments such as various tower crane, bridge crane, gauntry crane, transfer crane.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram;
In figure, 1 is main frame instrument box; 2 is sensors; 3 is transfer boxes; 4 is bearing seats; 5 is bases.
