Abstract
The invention relates to a stroke detection device for a crane steel rope. The stroke detection device comprises a pulley block composed of at least three pulleys, wherein a displacement sensor is arranged on one pulley. Compared with the prior art, the stroke detection device has the advantages as follows: as one pulley block is used, the close fit of the steel rope and the pulleys can be ensured, and the stroke of the hoisting steel rope can be precisely detected, the stroke detection device can carry out overwinding and overunwinding limiting of a crane and can accurately control the position of a grab hook. The invention further relates to a limiting and controlling method for a crane hoisting mechanism using the detection device.
Description
Technical field
The present invention relates to a kind of detecting device, particularly a kind of crane rope device for detecting distance of travel.
Background technology
At hoisting crane when using steel rope hoisting heavy, in order to ensure the use safety of hoisting crane, need to put spacing control to steel rope implementation pulleying is spacing with crossing.Wherein, hoisting crane pulleying is spacing mainly prevent from lifting hook from hoisting putting in place after, also continuing hoists causes machine to destroy and accidents caused; Hoisting crane cross put spacing mainly ensure steel rope be at least not less than on reel three circles be wound around, to ensure that steel rope is fixed on reel.
Spacing for hoisting crane pulleying, prior art is generally undertaken spacing by the weight switch being enclosed within hoist rope.And general pulleying inhibiting device is at the other weight of hanging of fixed pulley, on a steel cord, the rope hanging weight hauls a switch to cover, when lifting hook reaches maximum height of lift, jack-up weight, weight Cable forces loses, drag-line the switch that comes provide signal, now impose restrictions on the action that hoists.But, also need away line mechanism to carry out transmission of signal for telescopic jib class hoisting crane, use and adjust and comparatively bother.
Be directed to hoisting crane to cross and put spacing, prior art generally rotates the number of winning the confidence to determine that last three circle positions ensure by reel, because steel rope has different winding level on reel, therefore determines that last three circle precision are inadequate by reel position of rotation.
Summary of the invention
The invention reside in the shortcoming and deficiency that overcome prior art, a kind of device for detecting distance of travel of crane rope is provided, present invention also offers the spacing and control method of the crane rope by the trip detecting device.
The present invention is realized by following technical scheme: a kind of device for detecting distance of travel of crane rope, comprise the assembly pulley be made up of three pulleys, and wherein intermediate pulley is provided with displacement pickup.
Compared to prior art, the stroke detection that the present invention carries out steel rope by use one assembly pulley and sensor reaches pulleying and excessively puts spacing.When carrying out pulleying and being spacing, accurately can be recorded in the displacement stroke in the process of lifting by the displacement pickup on pulley, thus play and accurately control maximum height of lift.And when carrying out putting spacing, owing to needing last three circles being accurate to reel position of rotation, and by assembly pulley, can ensure steel rope with the fitting tightly of pulley, thus accurately can control the descending stroke of suspension hook.
Compared to prior art, the present invention reaches lifting altitude by the stroke detection that use one assembly pulley and sensor carry out steel rope and accurately controls.
Improve as another kind of the present invention, described assembly pulley comprises 3 pulleys, and what be wherein positioned at intermediate pulley is head pulley, and the pulley being positioned at head pulley two ends is auxiliary pulley; Described crane rope is hung on the bottom of this head pulley, and the two ends of this steel rope pass along the top of auxiliary pulley.
Further, described head pulley is provided with a force transducer.
Further, also comprise a controller, described controller is electrically connected with institute displacement sensors, in order to received bit displacement sensor signal and control the work of hoisting crane.
In hoisting operation process, can be detected single rope tension of hoist rope by force transducer, because lifting hook quality is fixed during empty hook, controller can calculate the multiplying power of hoist rope; Then carry a Time Controller and accurately can control lifting altitude hanging, can quantitatively hoist after data-oriented or decline.
Accompanying drawing explanation
Fig. 1 is the structural representation of crane rope inhibiting device of the present invention.
Detailed description of the invention
Refer to Fig. 1, it is the structural representation of crane rope device for detecting distance of travel of the present invention.Comprise the assembly pulley 1 be made up of side by side three pulleys, and wherein intermediate pulley is provided with displacement pickup.Concrete, in the present embodiment,
In order to understand better and implement, describe the present invention in detail below in conjunction with accompanying drawing.Described assembly pulley comprises 3 pulleys, and what be wherein positioned at intermediate pulley is head pulley 11, and the pulley being positioned at head pulley two ends is auxiliary pulley 12.Described crane rope 2 is hung on the top of this head pulley 11, and the two ends of this steel rope pass along the bottom of auxiliary pulley 12.
In the course of the work, the up-and-down movement realizing crane hook is rotated by reel.When carrying out pulleying and being spacing, accurately can be recorded in the displacement stroke in the process of lifting by the displacement pickup on pulley, thus play the stroke accurately controlling lifting.When this suspension hook runs to the position of setting, displacement pickup then now on pulley accurately can record the stroke of this lifting, and namely this lifting stroke reaches setting value, and this displacement pickup sends a signal to controller, control reel by this controller to quit work, realize pulleying spacing.
And when carrying out putting spacing, owing to needing last three circles being accurate to reel position of rotation, and by assembly pulley, can ensure steel rope with the fitting tightly of pulley, thus accurately can control the descending stroke of suspension hook.In like manner, when this suspension hook runs to the position of setting, then the displacement pickup now on pulley accurately can record the stroke of this lifting, and namely this lifting stroke reaches setting value, and this displacement pickup sends signal and directly controls reel and quit work; Also can send a signal to controller, control reel by this controller and quit work, realized putting spacing.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
