The invention provides a kind of wire rope locking device, wire rope locking device is a kind of topology example of the present invention as shown in Figure 1, comprises base 1, supports roll body 2, hold-down roller 3, spring 4 and electromagnetic draw bar 5.
Described base 1 structure as shown in Figure 2, fix respectively by base gusset 12, as the optional mode of one, also can be fixed by gusset in the bottom of two side arms 11 by two sides of two low wide and up narrow side arms 11, or by its integrated molding.Base fixed orifice 17 is had, for fixing wire rope locking device described in the present embodiment in electric capstan steel rope outlet front end in the bottom of base.On two side arms 11, correspondence position has four holes, be positioned at the electromagnetic draw bar mounting hole 13 of upside for Motionless electromagnetic pull bar 5, be positioned at the hold-down roller mounting hole 14 of rear end, downside for the roller 3 that is fixed and clamped, be positioned at the middle support roll body mounting hole 15 in downside for fixed pedestal roll body 2, be positioned at the spring hanging hole 16 of lower lateral front for fixing spring 4.
Described support roll body 2 structure as shown in Figure 3, be made up of support body and two backing rolls 22, support body respectively has a up-narrow and down-wide connecting panel 21 to be fixed by two pieces of gussets 23 by two ends, as the optional mode of one, and also can by leg-of-mutton for this kind framed structure integrated molding.On two connecting panels 21, correspondence position has three holes, and two the backing roll mounting holes 24 being positioned at upside, for fixed pedestal roller 22, are positioned at a backing roll fixed orifice 25 of downside for support roll body 2 is fixed on base 1.
Described hold-down roller 3 structure as shown in Figure 4, be made up of support body and a pressure roller 35, fixed by one piece of hold-down roller gusset 36 by two pieces of strip connecting plates 31 by support body, as the optional mode of one, and also can by this kind double-tee framed structure integrated molding.On two pieces of connecting panels 11, correspondence position has three holes, be positioned at the pressure roller fixed orifice 34 of upside for fixing pressure roller 35, the base connecting bore 32 being positioned at downside, for hold-down roller 3 is fixed on base 1, is positioned at middle electromagnetic draw bar fixed orifice 33 for Motionless electromagnetic pull bar 5.
As shown in Figure 5, respectively there is a hook at the two ends of its elastomeric element to described spring 4 structure, are respectively used to be fixed in base 1 and hold-down roller 3.The effect of spring 4 makes hold-down roller 3 press to all the time to support roll body 2.
Described electromagnetic draw bar 5 structure as shown in Figure 6, is made up of electromagnetism part 1 (51), electromagnetism part 2 (52) and pull bar 53.Electromagnetism part 1 (51) is connected by pull bar 53 with electromagnetism part 2 (52), electromagnetism part 2 (52) can slide up and down along pull bar 53, electromagnetism part 1 (51) is fixed on base 1, and electromagnetism part 2 (52) is fixed on hold-down roller 3.
Described pressure roller 35 is axially parallel with two backing rolls 22.
Preferably, described connecting panel 21 is heart-shaped, is convenient to pressure roller 35 and presses backing roll 22.
Connection mode:
Two backing rolls 22 supporting roll body 2 are connected with support body through the backing roll mounting hole 24 on two pieces of connecting panels 21 by mandrel, and there has been the jump ring of barrier effect at mandrel two ends, are conducive to the bearings of rolling between backing roll 22 and mandrel.
Supporting roll body 2 utilizes the backing roll fixed orifice 25 on its support body to be connected with base 1 by bearing pin free to rotate with the support roll body mounting hole 15 on base 1.
A pressure roller 35 of hold-down roller 3 is connected with support body through the pressure roller fixed orifice 34 on two pieces of strip connecting plates 31 by mandrel, and there has been the jump ring of barrier effect at mandrel two ends, are conducive to the bearings of rolling between pressure roller 35 and mandrel.
Hold-down roller 3 utilizes the base connecting bore 32 on its support body to be connected with base 1 by bearing pin free to rotate with the hold-down roller mounting hole 14 on base 1.Two springs 4 hang over respectively by one end in the spring hanging hole 16 of base 1 front end, and the mandrel two ends that the other end hangs over hold-down roller 3 are connected with base 1 and hold-down roller 3.On the electromagnetic draw bar mounting hole 13 that the electromagnetism part 1 (51) of two electromagnetic draw bars 5 utilizes rotatable bearing pin to be arranged on the upside of base 1, electromagnetism part 2 (52) utilizes rotatable bearing pin to be arranged on the electromagnetic draw bar fixed orifice 33 of hold-down roller 3.
As shown in Figure 7, during electric capstan work, the present embodiment wire rope locking device is installed on electric capstan steel rope outlet front end, and steel rope passes between two backing rolls 22 and a pressure roller 35.
Working process
When electric capstan forward or reverse starts, the electromagnet portion of electromagnetic draw bar 5 also switches on power, and electromagnetic draw bar 5 overcomes spring 4 elastic force pull-up hold-down roller 3 under the effect of electromagnetic force makes electric capstan steel rope pass through smoothly between support roll body 2 and three round rollers of hold-down roller 3; When electric capstan quits work power-off, electromagnetic draw bar 5 is without magnetic force, hold-down roller 3 is no longer acted on, hold-down roller 3 presses to and supports roll body 2 by hold-down roller 3 under the effect of spring 4 pulling force, three round rollers that electric capstan steel rope is subject to supporting roll body 2 and hold-down roller 3 mutually extrude and cannot move forward and backward, and the steel rope now on electric capstan cylinder can not relax, can not expand.
Principle of work
When electric capstan works, under the effect of load, steel rope is straightened, now, because electromagnetic draw bar 5 overcomes spring 4 pulling force under electromagnetic force, hold-down roller 3 is mentioned, make can through the steel rope supported roll body 2 and three round rollers of hold-down roller 3 resistantly not pass through smoothly, electric capstan can not because of the existence of wire rope locking device extra work; When electric capstan quits work, owing to there is no load, steel rope is the fluffy spreading of meeting under rigidity effect within it, now, no longer have an effect to hold-down roller 3 because electromagnetic draw bar 5 loses electromagnetic force, the pressure roller 35 of hold-down roller 3 only inwardly presses two backing rolls 22 supporting roll body 2 under the pulling force effect of spring 4, and then press the steel rope passed in the middle of it, make the stressed rigidity application force overcoming its inherence of steel rope, no longer bounce back expansion, and then keep it to be tightly wound around electric capstan state.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any people being familiar with this technology is in the technical scope disclosed by the present invention; the conversion and replacement expected can be understood; all should be encompassed in and of the present inventionly comprise within scope, therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
