Abstract

The utility model relates to a ropeway clamp ring clamping type loading pressure cable pulley especially suitable for the passenger aerial ropeway. The main technology characteristic thereof is to change the inclined plane contact end of the internal and the external side plates and the clamp ring in the prior technology to a part composed of the inclined plane of the contactless segment and the 90 DEG wrap angle arc surface of the contact segment, the improvement changes the contacts of the clamp ring and the internal and the external side plates from line contacts to surface contacts, and the constraint wrap angle is changed from 225 DEG to 270 DEG, so as to completely eliminate the clamp ring falling and the wheel liner slip phenomenon, and guarantee the safe operation of the ropeway.

Description

The clamped supporting and pressing cable pulley of cableway collar

1, technical field

The utility model relates to the improvement of the clamped supporting and pressing cable pulley of a kind of cableway collar, is specially adapted to the supporting and pressing cable pulley of passenger aerial ropeway.

2, background technology

The clamped supporting and pressing cable pulley side plate of traditional cableway collar is generally 45 ° of inclined-planes with the end face that contacts of collar, and for line contacts, practice shows that this way of contact exists collar and falls circle and wheel lining sliding phenomenon between side plate and the collar.Though its occurrence frequency is little, it is very harmful.

3, summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of clamped supporting and pressing cable pulley side plate of cableway collar that can eliminate above-mentioned hidden danger.Its basic ideas are, existing chamfered portion is modified into one section is the unitized construction of another section of inclined-plane for the cambered surface consistent with the collar cross sectional shape, inside and outside lateral plate structure like this is after wheel lining compression assembling, collar is contacted by line with the side plate contact position and becomes the face contact, the stressed constraint cornerite in back increases because inclined-plane and cambered surface intersect or tangent line of position raises simultaneously, further lock collar, thereby prevent from because of the bigger blockade collar of unconfinement cornerite interface distance broad the accident potential that collar falls to enclose may take place because of not enough accident and the collar that produces slippage of the lining clamping magnitude of interference appears taking turns in side plate line contact premature wear easily.Concrete technical scheme of the present utility model is:

The clamped supporting and pressing cable pulley side plate of a kind of cableway collar, relate to wheel body, inside and outside collar, interior outer panel, the wheel lining in being sandwiched between the outer panel, wherein the place of keeping to the side, both sides, the wheel body outside has all drawn annular groove, the bottom of inside and outside collar all places annular groove, the contacting on the end face of outer panel and collar in top is stuck in is characterized in that: interior outer panel is non-contacting inclined-plane with one section of the end face that contacts of separately collar, and another section (contact segment) is the arcwall face consistent with the collar cross sectional shape.

Further scheme is, when the collar cross sectional shape was circle, described contact segment cambered surface was and the consistent arc surface of circular collar arc shape.

Scheme is preferably, and the noncontact bevel phase of described outer panel is 20 ° of inclined-planes.

Better scheme is that the noncontact bevel phase of described interior plate is 45 ° of inclined-planes.

5, embodiment

Below in conjunction with accompanying drawing the utility model is done detailed description.

As Fig. 1, the wheel body 1 outer interior outer panel 3 of the existing clamped supporting and pressing cable pulley of collar is 45 ° of inclined-planes with 4 with the end face that contacts of corresponding collar 2, the assembling back serves as a contrast under the effect of 5 elastic reactances at rubber wheel, collar 2 is toroids with the contact position on corresponding side plate 3 or 4 inclined-planes, and the stressed back of the collar maximum cornerite of constrained force is 225 °.

As Fig. 2, the contact end face of the outer panel 3 of the clamped supporting and pressing cable pulley of collar described in the utility model and corresponding outer collar 2 constitutes by 20 ° of bevel phase of one section the same with the collar radius 90 ° of cornerite arc surface and raised position are crossing; Interior plate 4 with corresponding in the contact end face of collar 2 intersect by 45 ° of inclined-planes of the arc surface the same of one section 90 ° of cornerite and raised position and constitute with interior collar 2 radiuses.This shows that improving stressed place, back is the face contact, its constraint cornerite is 270 °.This side plate 3 and 4, except that serve as a contrast at the assembling rubber wheel to note in 5 o'clock dress outer panel 3 earlier on one side collar 2, refill wheel lining 5 and interior plate 4 and in outside the collar 2, all the other programs are the same with the assembling process of prior art.

As Fig. 3 and Fig. 4, as seen from the figure, the outer panel 3 after the improvement is that one section 20 ° of inclined-plane and one section 90 ° of cornerite arc surface constitute with the end face that contacts of collar.

As Fig. 5 and Fig. 6, as seen from the figure, the interior plate 4 after the improvement is that one section 45 ° of inclined-plane and one section 90 ° of cornerite arc surface constitute with the end face that contacts of collar 2.

With cableway circle nominal diameter Φ 400mm cable pulley is example, its collar diameter is Φ 5mm, collar is contacted by line with side plate and becomes the face contact after improving, simultaneously rise to 90 ° of direction places with the inclined-plane intersection, its stressed constraint cornerite rises to 270 ° by 225 °, and the stressed cornerite of unconfinement is reduced to 90 ° by 135 °.Learnt that by calculating collar is reduced to 3.536mm in constraint cornerite interface point place chord length by 4.620mm, promptly the opening direction drop lock increases to 5-3.536=1.464mm by 5-4.620=0.38mm, has obviously increased the locking action to collar.
