Abstract
A deviation detecting device for crane sling relates to the hoisting machinery. The utility model solves the technical problem that the current detecting device is bad in reliability and high in manufacturing cost. The utility model comprises a crane double drum, a pulley shaft, a balance pulley, a steel wire rope and a sling. The steel wire rope is twined via the sling and balance pulley and two ends thereof are fixed on the double drum. The balance pulley can be rotated to the pulley shaft. The utility model is characterized in that an angle sensor is installed at the side of the balance pulley. The utility model is suitable for detecting the sling of the crane. The utility model has the advantages of being low in manufacturing cost and high in detecting reliability.
Description
Technical field
The utility model relates to elevator machinery, particularly a kind of suspender detecting device of hoisting crane.
Background technology
In the process of crane loading weight, often because the center of gravity of weight is not former thereby cause suspender to produce deflection at the lifting center etc.When deflection is excessive, can bring extra increment load to hoisting crane, influence the normal operation of hoisting crane, can cause the hoisting crane damage when serious or weight is dropped.Therefore, the plumbness of crane hanger is detected, prevent that the suspender deflection is very important.At present; Detect the technical scheme of crane hanger deflection; Be on hoisting crane equalizer pulley axle, high-precision encoder to be installed; Read the number of turns (pulse count) that sheave shaft turns over, by crane control system pulse count is converted into angle through calculating again, thereby detect the state of crane hanger deflection.The detecting device of prior art, not only poor reliability, and requirement is carried out particular design and processing to the equalizer pulley axle, has increased the manufacturing cost of hoisting crane.
Summary of the invention
The purpose of the utility model is intended to overcome the shortcoming of prior art, and a kind of crane hanger deflection detecting device is provided, and solves existing detecting device poor reliability, the technical matters that manufacturing cost is high.
The utility model is to realize through following technical scheme:
A kind of crane hanger deflection detecting device; Comprise: hoisting crane double crosslinking drum, sheave shaft, equalizer pulley, steel rope, suspender; Said steel rope is fixed on the double crosslinking drum through suspender, equalizer pulley winding and two ends, and equalizer pulley can rotate with respect to sheave shaft; It is characterized in that: setting angle sensor on the side of said equalizer pulley.
The utility model compared with prior art; Because direct mount angular transducer on equalizer pulley can directly be measured the angle excursion of suspender and feed back to crane control system, therefore; The utility model has reduced the manufacturing cost of hoisting crane, has improved the reliability that deflection detects.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is a kind of steel rope winding figure of the utility model.
The utility model is further described through embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 1, shown in 2; A kind of crane hanger deflection detecting device; Comprise: hoisting crane double crosslinking drum 3, sheave shaft 2, equalizer pulley 4, steel rope 5, suspender 6; Said steel rope 5 is fixed on the double crosslinking drum 3 through suspender 6, equalizer pulley 4 windings and two ends, and equalizer pulley 4 can rotate with respect to sheave shaft 2; Setting angle sensor 1 on the side of said equalizer pulley 4.
The utility model working process:
In the hoisting heavy process; During suspender 6 deflections, drive equalizer pulley 4 through steel rope 5 and rotate, at this moment with respect to sheave shaft 2; Angular transducer 1 detects the angle that equalizer pulley 4 relative vertical positions turn over; And give crane control system with this data transfer, just know the suspender deflected condition of this moment, so that take safe precaution measure.
