Abstract
The utility model provides a comprehensive safety protection device of hoisting equipment, which belongs to the technical field of the designing and manufacturing of the safety protection device of hoisting machinery. A display controller is connected on an electrical control cabinet, a wire distributing box is connected at the output end of the display controller, a weighing sensor is arranged at one end of each wire distributing box, and a height compensator is arranged at the other end of each weighing sensor; the two weighing sensors are arranged below a drum roller moving shaft of the hoisting equipment, and the two height compensators are respectively arranged on a main drum shaft. The two weighing sensors detect the load of the crane, and convert a weight signal into a voltage signal proportional to the weight. Meanwhile, the two height compensators convert the weight signal of a steel wire rope for releasing length into the voltage signal proportional to the weight. The two paths of signals are sent to the display controller after being gathered by the wire distributing box. A circuit in the display controller carries out data collecting, measuring, amplifying, filtering and A/D converting; and then a CPU carries out data processing, displaying and judging. With simple structure and reasonable design, the ideal safety protection device of the hoisting equipment can control the acousto-optic alarm and an ascending control loop of the hoisting equipment according to the weight signal.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of elevator machinery safety guard.
Background technology
The work of elevator machinery is exactly the article that the handling volume is big, weight is big, often occurs the overload phenomenon in the operation.The overload operation of elevator machinery can cause mechanical girder bending-down bending, and badly damaged parts make machinery shortening in service life.Cause personal injury and substantial equipment safety misadventure when serious.Cause heavy losses to enterprise.And in hoisting operation, can only judge whether to exceed the elevator machinery load at present according to judged its weight by the volume of handling article, material.So often make a fault and lead to safety misadventure.
Summary of the invention
At existing situation, the purpose of this utility model provides a kind of safety guard of weight-lifting equipment, with the safe operation of preventive device, avoids the generation of all kinds of accidents.
Structure of the present utility model is as shown in drawings: connect a display control switch on electrical control cubicles.The mouth of display control switch connects a distribution box without protectors.One end of distribution box without protectors connects an A LOAD CELLS and B LOAD CELLS respectively.Connect an A altimetric compensation device and B altimetric compensation device on the other end of distribution box without protectors respectively.Display control switch connects a large screen display by data line.Electrical control cubicles of the present utility model and display control switch are arranged in the operator's compartment of elevator machinery.Two LOAD CELLS are placed in the below of the platen roller moving axis of weight-lifting equipment, and the platen roller moving axis has been held up, and the base of LOAD CELLS is fixed on the crossbeam of hoisting crane.Two altimetric compensation devices are contained on the spool spindle respectively.Large screen display is arranged in the operation department.Principle of work of the present utility model is: the load of hoisting crane is detected by two LOAD CELLS, and weight signal is converted to and the proportional voltage signal of weight.Two altimetric compensation devices convert the weight signal that steel rope discharges length and the proportional voltage signal of weight to simultaneously.Two paths of signals is given display control switch after gathering by distribution box without protectors.Carry out data acquisition, measurement amplification, filtering, A/D conversion by circuit in the display control switch, carry out data handing by CPU then, data display, judgement.The control loop that hoists according to weight signal control sound and light alarm and control weight-lifting equipment.When hoisting weight reach rated value 90 percent the time, display control switch generation early warning signal, yellow indicator lamp is bright, buzzer phone sends pulsed sound, reminds operating personal to note.When the hoisting weight overrate, red indicating light is bright, the continuous sounding of buzzer phone.And cut-out hoisting circuit power supply.Machinery stops handling weight to be lifted reduces to below the rated value, and relay just can be extensive wilful.The utility model is simple in structure, and is reasonable in design, the degree of automation height, and showing by experiment to provide the most accurate weighing and the most perfect safety guard-safeguard.It is a kind of desirable weight-lifting equipment safety guard.
