The looseness-proof rope protection device is characterized by comprising a tension adjustment base plate with adjustable height, wherein the tension adjustment base plate is connected with a stressed core shaft through a connecting frame on the tension adjustment base plate; the periphery of the stressed core shaft is connected with a steel wire rope guide wheel through bearings; a pressure sensor which can sense the stress conditions of the stressed core shaft is arranged inside the stressed core shaft; and the electric signal output end of the pressure sensor is connected with a hoist control circuit which is used for controlling a hoist to work. The looseness-proof protection device quickly responses, can be safely and reliably used, can effectively prolong the service life of the steel wire rope and has the advantages of simple structure, low failure rate and long service life.
Description
Technical field
The utility model relates to crane manufacturing technology field, particularly a kind of anti-slack rope fender guard of steel rope that is used for crane.
Background technology
Crane is widely used in the loading and unloading of Cargo On Deck.And in the process of unloading, emit longly in order to prevent steel rope, and cause steel rope lax, crooked, thereby cause steel rope entanglement when reclaiming to be arranged, twine each other, even damage, the locking rope device of steel rope just need be set.But in the prior art, mostly the locking rope device of steel rope is physical construction, adopts traditional mechanical position limitation sensor to carry out spacing triggering; This device is not only slow in reacting, and reliability of service is low, and complex structure; And use mechanical wear is big, and fault rate is high, and result of use is not good.
Summary of the invention
The purpose of the utility model is to provide a kind of anti-slack rope fender guard of steel rope that is used for crane, and this device not only is swift in response, and is safe and reliable, can effectively prolong steel rope service life, and apparatus structure is simple, and fault rate is low, long service life.
The technical scheme that the utility model adopts is: a kind of anti-slack rope fender guard of steel rope that is used for crane; Comprise adjustable for height tension adjustment seat board; Said tension adjustment seat board is connected with stressed axle through link span provided thereon; Said stressed axle peripheral part is connected with the steel rope guide wheel through bearing; But said stressed axle inside is provided with the pressure sensor of the stressed axle force-bearing situation of sensing, and the electrical signal of said pressure sensor is connected with the winch control circuit that is used to control winch work.
The beneficial effect of the utility model is to have cancelled traditional mechanical position limitation sensor, and adopts Piezoelectric sensing technique, is swift in response, and has mentioned the safety and the reliability that use greatly, has effectively prolonged the service life of steel rope.In addition, this apparatus structure is simple, and manufacture difficulty is low, and compared to traditional locking rope device, it is little to have use mechanical wear, and fault rate is low, and advantages such as long service life have wide market application prospect.
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the working state schematic representation of the utility model embodiment.
Fig. 3 is the control principle figure of the utility model embodiment.
The specific embodiment
The utility model is used for the anti-slack rope fender guard of steel rope of crane; Like Fig. 1, shown in 3; Comprise adjustable for height tension adjustment seat board 1; Said tension adjustment seat board 1 is connected with stressed axle 3 through link span provided thereon 2, and said stressed axle 3 peripheral parts are connected with steel rope guide wheel 5 through bearing 4, and said steel rope guide wheel 5 is between winch 10 and work guide wheel 11; But said stressed axle 3 inside are provided with the pressure sensor 6 of the stressed axle force-bearing situation of sensing, and the electrical signal 7 of said pressure sensor 6 is connected with the winch control circuit that is used to control winch 10 work.
In order to calculate the hoisting weight of crane, above-mentioned pressure sensor 6 is the piezoelectric type force transducer, with the stressed size of the stressed axle of sensing 3 and be translated into the electric weight electric signal output of corresponding size.
In the present embodiment, above-mentioned stressed axle 3 is a stationary spindle, and stressed axle 3 and said link span 2 are for captiveing joint.
In order to give stressed axle 3 with the force transmission of steel rope guide wheel 5, but above-mentioned bearing 4 is the bearing of bearing radial force, like deep groove ball bearing, cylindrical roller bearing etc.
In order to realize the adjustable of height; Mentioned strain is regulated seat board 1 and is connected on the crane frame 9 through tension adjustment bolt 8; Change the height of tension adjustment seat board 1 with the screw-in depth of passing through tension adjustment bolt 8, thereby regulate the size of steel rope steel rope guide wheel tension force.
As shown in Figure 2; During installation; The utility model device is installed between winch 10 and the work guide wheel 11; Steel rope on the winch 10 is outwards drawn and connecting shackle after walking around steel rope guide wheel 5 and work guide wheel 11, suitably adjusts the height of tension adjustment seat board 1, makes steel rope guide wheel 5 tensioning steel ropes.During lifting cargo; The steel rope tensioning produces the tension force effect to steel rope guide wheel 5, and steel rope guide wheel 5 passes to stressed axle 3 with application force through bearing 4; At this moment; The size that the stressed axle of pressure sensor 6 sensings 3 is stressed, and the electric weight electric signal that is translated into corresponding size exports to the winch control circuit, to calculate hoisting weight.In this course, because goods to the pull of steel wire effect, makes steel rope keep tensioning state always.When unloading goods, winch 10 is constantly emitted steel rope, unloads until goods; At this moment, because goods reduces pull of steel wire, make the stressed also corresponding of stressed axle 3 reduce; The winch control circuit senses application force less than setting value through pressure sensor 6; Promptly export a control signal and give winch 10, it is quit work, thus reach prevent that steel rope is lax, twine purpose.
More than be the preferred embodiment of the utility model, all changes of being done according to the utility model technical scheme when the function that is produced does not exceed the scope of the utility model technical scheme, all belong to the protection domain of the utility model.
