Description
Technical field:
The present invention relates in general to mechanical field, more specifically, relates to a kind of anti-skidding rope sheave of traction, lifter.
Background technology:
In the application of a lot of descending lifelines and towing machine; conventionally there will be because cornerite between rope and rope sheave is too small, the acceleration/accel of traction system starting and braking is excessive, work rope is lubricated or lubricating method not at that time; all may cause rope and take turns relative skidding between grooving; thereby have a strong impact on use; even the safety of equipment is brought to hidden danger; especially the rope slipping of fall-slowing device for rescuing from high building, directly injures survivor's life security.Therefore skid relative with grooving on rope sheave edge of rope becomes a problem that must solve.
For example, in the slow escaping descent control device falling by deadweight, the rope sheave of governor is very important parts.Existing a kind of technology is that race adopts common " V " type groove, is provided with outstanding rib and prevents from skidding on the two side of race.Separately having a kind of technology is belt pulley with microwave shape cross-section, be exactly pulley groove two sides be not plane but the very little curved surface of wave amplitude.Adopt above technical scheme, although there is certain anti-skidding effect, but the area of contact of rope and race reduces, after tested, when rope is lubricated, overload or while playing the abnormal factorses such as the excessive Huo Yasheng of braking acceleration mechanism is malfunctioning, just easily produces and skid, rope slightly skids, because inertia will be out of control, just there is acceleration/accel moment, can not receive for one.Occurring this situation, is extremely dangerous to user, even can fall to death.
Summary of the invention:
For solving the problems of the technologies described above, the object of this invention is to provide a kind of relative defect of skidding between race and work rope that can overcome in prior art on rope sheave edge.
The invention provides a kind of anti-skidding rope sheave, wherein, on described rope sheave, be provided with axial waveform helical wheel groove.
According to an embodiment of the invention, wherein, described axial waveform helical wheel groove is comprised of groove, wheel cell wall and anti-slip sucking disc.
According to an embodiment of the invention, wherein, described groove comprises a kind of groove of making axial waveform spiral along wheel rim.
According to an embodiment of the invention, wherein, described groove, its grooved comprises V-type and U-shaped, its width of rebate mates with the external diameter of rope.
According to an embodiment of the invention, wherein, described wheel cell wall comprises from the waveform groove mouth of groove and is transitioned into the domatic of the straight rim in both sides.
According to an embodiment of the invention, wherein, two side slopes of described wheel cell wall are evenly provided with anti-slip sucking disc.
According to an embodiment of the invention, wherein, described anti-slip sucking disc comprises a kind of rounded, umbilicate plate-like.
According to another aspect of the invention, provide a kind of side for the anti-skidding rope sheave of race, belt pulley, traction sheave, holder rope sheave
Utilize technical scheme provided by the invention, can effectively solve on rope sheave edge relative skidding between race and rope, guaranteed the result of use of rope and rope sheave, thereby made its operational process more safe and reliable.
Accompanying drawing explanation:
Describe in conjunction with the drawings embodiments of the present invention, make those skilled in the art have more clear and thorough understanding to the present invention.Wherein:
Fig. 1 shows according to the block diagram of the anti-skidding rope sheave of one embodiment of the present invention;
Fig. 2 shows the contact form schematic diagram according to the rope described in one embodiment of the present invention and race;
Fig. 3 shows according to the groove mouth expansion drawing described in one embodiment of the present invention.
Label declaration: 1 anti-skidding rope sheave is overall, 2 ropes, 10 axial waveform helical wheel grooves, 11 grooves, 12 take turns cell wall, 13 anti-slip sucking discs.
The specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.It will be appreciated that, accompanying drawing and following description are only examples, and it can not limit the scope of the invention.
Fig. 1 shows according to the block diagram of the anti-skidding rope sheave of one embodiment of the present invention.
As shown in Figure 1, according to a kind of anti-skidding rope sheave of an embodiment of the invention, be totally expressed as 1.On anti-skidding rope sheave 1, be provided with axial waveform helical wheel groove 10.Axially waveform helical wheel groove 10 consists of groove 11, wheel cell wall 12, anti-slip sucking disc 13.Groove 11 is made axial waveform spiral along wheel rim, and wheel cell wall 12 comprises that waveform groove mouth is transitioned into the domatic of the straight rim in both sides, and anti-slip sucking disc 13 is distributed near two side slopes groove mouth.
It will be appreciated that, be one although Fig. 1 illustrates the quantity of race 10, and the present invention is not limited to any specific quantity, and those skilled in the art can select the quantity of actual needs as required.
Fig. 2 illustrates rope 2 and the situation that waveform spiral race 10 contacts, and makes those skilled in the art have more clear and thorough understanding to the present invention.
As shown in Figure 2, width of rebate mates with the diameter of rope 2.Rope 2 is wrapped in 10 li of waveform spiral races, compared with prior art, has greatly increased the area of contact of wheel cell wall 12 with rope 2.When rope 2 one end are subject to radial pull F, rope 2 will enter 11 li of grooves by down, rope 2 is by domatic the clamping of waveform on wheel cell wall 12 simultaneously, degree of tightness and tensile force f between rope 2 and wheel cell wall 12 are proportional, tensile force f is larger, rope 2 is just held tighter 10 li of races, cause and be not easy to skid.
As Fig. 1, Fig. 2 is shown on race wall 12 both sides domatic and is provided with uniform anti-slip sucking disc 13, rounded according to an embodiment of the invention anti-slip sucking disc 13, umbilicate plate-like, mainly be distributed near two side slopes of groove 11 notches, strengthen the adhesive ability of 12 pairs of ropes of wheel cell wall, especially when the lubricated liquid of rope is stained with, when through wheel-through groove 10, anti-slip sucking disc 13 is by oppressing in opposite directions rope 2, lubricating fluid is just extruded, with forming vacuum in hour indicator chamber, by degree of vacuum, maintain and adhere to not separated with rope 2, thereby while making the lubricated or faulty lubrication of rope 2, can not skid with grooving 10 easily yet.
Fig. 3 shows the notch axial section expansion drawing of groove 11, according to an embodiment of the invention, further illustrates the version of groove 11.It will be appreciated that, the wave amplitude of groove shown in figure 11 and the shape of wave band, be a legend of an embodiment of the invention, and the present invention is not limited to this, those skilled in the art can, with reference to legend, carry out groove 11, cell wall 12 and the anti-slip sucking disc 13 of Optimum Matching according to the thickness of rope.
Also it will be appreciated that, although the axial waveform helical wheel groove 10 in diagram is to take the center of circle to carry out the circular rope sheave of spiral as axle, but technical scheme of the present invention can be applicable to the wheel of other shapes too, swivel of eccentric wheel and any other shape etc. for example.
According to another aspect of the invention, also provide a kind of method for the anti-skidding rope sheave of race, belt pulley, holder rope sheave, comprising: the axial waveform helical wheel groove and the anti-slip sucking disc that on described wheel body edge, arrange.
It will be appreciated that, above description of the invention is only example, and those skilled in the art can make various interpolations, delete, revises or combination and do not depart from the scheme that the present invention protects.
