Abstract
The utility model discloses a reclaimer power cable fairlead, guide roll including locating the casing top is right, and the guide roll of locating the casing middle part is right, the casing lower part articulates there is the digging arm, the digging arm lower extreme is fixed at swing fender wheel epaxially, this swing keeps off the epaxial return spring that is equipped with of wheel, the digging arm upper end is equipped with inductive switch, buting iron on this inductive switch and the casing outer wall matches and connects, the reclaimer power cable run through in the casing, so that power cable is when together removing the in -process by the take -up along with the reclaimer, it keeps off the wheel swing to drive the swing, make inductive switch touch the buting iron thereupon the wobbling in -process and send the taut signal of cable at the removable wall. The utility model discloses can increase and lead the cable tension and walk to go and stop chain protect function, prevent that the cable atress from tightly breaking the cable, prevent cable distortion, extension cable life, it stops to walk the line to be that equipment is chain through the detection, prevents effectively that the cable is because of the excessive damage of atress.
Description
Technical field
The utility model relates to a kind of power cable leadfair, and particularly a kind of reclaimer power cable leadfair, belongs to mechanical equipment technical field.
Background technology
Because cable is when bucket-wheel stacker reclaimer is walked, be in mobile curling and tension state always, and working environment is in outdoor again, the therefore direct impact of climate and stockyard dust, requires that power cable must have higher mechanical strength, soft crimpability and climate adaptability.In order to ensure that cable drum normally works, uniformity is required to the profile physical dimension of cable.Former leadfair is then easily out of shape after using a period of time, and displacement track adjusting wheel wheel face cannot keep the level and smooth flexible of cable for a long time.Therefore, be necessary to be improved prior art.
Summary of the invention
For the service life, the maintenance cable that extend cable smoothly stretch, the utility model provides a kind of reclaimer power cable leadfair, and cable pressure is alleviated, and service life is extended.
The utility model is realized by following technical proposal: a kind of reclaimer power cable leadfair, comprise housing, be located at the guiding roller pair above housing, be located at the guiding roller pair of housing central section, it is characterized in that: lower housing portion is hinged with movable arm, described movable arm lower end is fixed on and swings on gear wheel wheel shaft, this swing gear wheel wheel shaft is provided with pull back spring, movable arm upper end is provided with inductive switch, buting iron on this inductive switch and housing exterior walls is matched, reclaimer power cable is through in housing, so that when power cable is tightened up in reclaimer together moving process, drive while swinging gear wheel swing, make inductive switch touch buting iron in removable wall is thereupon the process swung and send cable tension signal, thus remind operator, after ring off signal, swing gear wheel return under pull back spring effect.
Guiding roller above described housing is right to being set to two, longitudinally place for a pair, another to horizontal placement, cable is imported housing from four direction.
Described housing by forward and backward plate and the guiding roller be located in the middle part of forward and backward plate to forming.
Described swing gear wheel is set to two, is placed between forward and backward plate bottom respectively by wheel shaft, and great wheel arbor is connected with corresponding movable arm respectively, is provided with same spring simultaneously, or is connected with respective spring respectively between great wheel arbor.
Be hinged on case front plate by hinge in the middle part of described movable arm.
Described inductive switch, induction buting iron are arranged on case front plate, and are connected with the alarming device of operation room or breaker device.
Be connected to cable on reclaimer power plant through reel from upper guiding roller between penetrate, again through in guiding roller subtend downward-extension until cable box, when cable to move with reclaimer left or right and reach capacity position time, cable is tightened compressing swing gear wheel and is outwards swung, and drive movable arm to rotate around hinge, the inductive switch on movable arm is made to touch buting iron, namely the alarming device between making operation or breaker device, remind operating personal or directly make reclaimer stop movement or reversing sense to move, when after releasing cable limiting situation, swing gear wheel return is made under pull back spring effect, movable arm wraparound, inductive switch and buting iron are thrown off.
The advantage that the utility model possesses and effect: the device that the utility model provides can increase leads cable tension traveling stopping interlock protection function, prevent that cable is stressed strains at power-off cable, cable guiding dead angle is reduced in upper and lower cable rolling process, cable pressure alleviates, prevent distortion of the cable, extend cable service life; By detect be equipment interlocking stop traveling, effectively prevent cable from damaging because of overstress.The utility model structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is right TV structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
As Fig. 1 and 2, reclaimer power cable leadfair comprises housing 3, be located at guiding roller above housing 3 to 1, 2, be located at the guiding roller of housing central section to 4, wherein, housing 3 lower hinge has movable arm 6, described movable arm 6 lower end is fixed on and swings on gear wheel 8 wheel shaft, this swing gear wheel 8 wheel shaft is provided with pull back spring 7, movable arm 6 upper end is provided with inductive switch 9, this inductive switch 9 is matched with the buting iron 10 on housing 3 outer wall, reclaimer power cable 11 is through in housing 3, so that when power cable 11 is tightened up in reclaimer together moving process, drive while swinging gear wheel 8 swing, make inductive switch 9 touch buting iron 10 in removable wall 6 is thereupon the process swung and send power cable 11 to strain signal, thus remind operator, after ring off signal, swing gear wheel 8 return under pull back spring 7 acts on.
It is two right that guiding roller above described housing 3 is set to 1,2, longitudinally place for a pair, another to horizontal placement, power cable 11 is imported housing 3 from four direction; Housing 3 is made up of 4 forward and backward plate and the guiding roller be located in the middle part of forward and backward plate; Swing gear wheel 8 and be set to two, be placed between forward and backward plate bottom respectively by wheel shaft, great wheel arbor is connected with corresponding movable arm 6 respectively, is provided with same spring 7 simultaneously, or is connected with respective spring respectively between great wheel arbor; Be hinged on case front plate by hinge 5 in the middle part of movable arm 6; Described inductive switch 9, induction buting iron 10 are arranged on case front plate, and are connected with the alarming device of operation room or breaker device.
Be connected to power cable 11 on reclaimer power plant through reel self-steering roller to 1, penetrate between 2, again through guiding roller to 4 to downward-extension until cable box, when power cable 11 to move with reclaimer left or right and reach capacity position time, power cable 11 is tightened compressing swing gear wheel 8 and is outwards swung, and drive movable arm 6 to rotate around hinge 5, the inductive switch 9 on movable arm 6 is made to touch buting iron 10, namely the alarming device between making operation or breaker device, remind operating personal or directly make reclaimer stop movement or reversing sense to move, when after releasing power cable 11 extreme condition, swing gear wheel 8 return is made under pull back spring 7 acts on, movable arm 6 wraparound, inductive switch 9 and buting iron 10 are thrown off.
