The looseness-preventing rope protection device is fast in response, is safe and reliable in using, can effectively prolong the service life of the steel wire rope, and is simple in structure, low in failure rate and long in service life.
Description
Technical field
The present invention relates to crane manufacturing technology field, particularly the anti-rope-loosing protection device of a kind of steel rope for crane.
Background technology
Crane is widely used in the handling of Cargo On Deck.And in the process of unloading, long in order to prevent steel rope from releasing, cause steel wire rope looseness, bend, thus cause steel rope entanglement arrangement when reclaiming, be mutually wound around, even damage, just need to arrange steel rope Anti-loosing device.But in the prior art, steel rope Anti-loosing device mostly is physical construction, traditional mechanical position limitation sensor is adopted to carry out spacing triggering, this device is not only slow in reacting, and reliability of service is low, and complex structure, and use procedure mechanical wear is large, fault rate is high, and result of use is not good.
Summary of the invention
The object of the present invention is to provide the anti-rope-loosing protection device of a kind of steel rope for crane, this device is not only swift in response, safe and reliable, can effective prolonging service life of steel wire, and apparatus structure is simple, failure rate is low, long service life.
The technical solution used in the present invention is: the anti-rope-loosing protection device of a kind of steel rope for crane; comprise adjustable for height tension adjustment seat board; described tension adjustment seat board is connected with stressed axle through link span provided thereon; described stressed axle peripheral part is connected with steel rope guide wheel through bearing; described stressed mandrel interior is provided with the pressure sensor that can sense stressed axle force-bearing situation, and the electrical signal of described pressure sensor is connected with the winch control circuit for controlling winch work.
The invention has the beneficial effects as follows and eliminate traditional mechanical position limitation sensor, and adopt Piezoelectric sensing technique, be swift in response, greatly refer to the safety and reliability of use, effectively extend the service life of steel rope.In addition, this apparatus structure is simple, and manufacture difficulty is low, compared to traditional Anti-loosing device, has use procedure mechanical wear little, failure rate is low, the advantages such as long service life, has wide market application foreground.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the working state schematic representation of the embodiment of the present invention.
Fig. 3 is the control principle drawing of the embodiment of the present invention.
Detailed description of the invention
The present invention is used for the anti-rope-loosing protection device of steel rope of crane, as Fig. 1, shown in 3, comprise adjustable for height tension adjustment seat board 1, described tension adjustment seat board 1 is connected with stressed axle 3 through link span 2 provided thereon, described stressed axle 3 peripheral part is connected with steel rope guide wheel 5 through bearing 4, described steel rope guide wheel 5 is between winch 10 and work guide wheel 11, described stressed axle 3 inside is provided with the pressure sensor 6 that can sense stressed axle force-bearing situation, the electrical signal 7 of described pressure sensor 6 is connected with the winch control circuit worked for controlling winch 10.
In order to calculate the hoisting weight of crane, above-mentioned pressure sensor 6 is piezoelectric type force transducer, with sense the stressed size of stressed axle 3 and be translated into corresponding size electricity electric signal export.
In the present embodiment, above-mentioned stressed axle 3 is stationary spindle, and stressed axle 3 and described link span 2 are for being fixedly connected with.
In order to give stressed axle 3 by the force transmission of steel rope guide wheel 5, above-mentioned bearing 4 is the bearing that can bear diametral load, as deep groove ball bearing, cylindrical roller bearing etc.
In order to realize the adjustable of height, mentioned strain regulates seat board 1 to be connected in crane frame 9 through tension adjustment bolt 8, to be changed the height of tension adjustment seat board 1 by the screw-in depth of tension adjustment bolt 8, thus regulate steel rope to the size of steel rope guide wheel tension force.
As shown in Figure 2, during installation, apparatus of the present invention be installed between winch 10 and work guide wheel 11, the steel rope on winch 10 walks around steel rope guide wheel 5 and the work backward outer extraction of guide wheel 11 connecting shackle, the height of suitable adjustment tension adjustment seat board 1, makes steel rope guide wheel 5 tensioning steel rope.During lifting cargo, steel wire tensioning, tension force effect is produced to steel rope guide wheel 5, application force is passed to stressed axle 3 through bearing 4 by steel rope guide wheel 5, now, pressure sensor 6 senses the stressed size of stressed axle 3, and the electricity electric signal being translated into corresponding size exports to winch control circuit, to calculate hoisting weight.In this course, because goods is to the pulling force effect of steel rope, make steel rope keep tensioning state always.When unloading goods, winch 10 constantly releases steel rope, until goods unloads, now, because goods reduces the pulling force of steel rope, make the stressed also corresponding reduction of stressed axle 3, winch control circuit senses application force by pressure sensor 6 and is less than setting value, namely export a control signal to winch 10, make it quit work, thus reach prevent steel wire rope looseness, winding object.
Be more than preferred embodiment of the present invention, all changes done according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
