Abstract
The utility model discloses a kind of double ring type rotating hoisting rings, including collar (1), stop washer (2), screw (3), lid (4), graphite self-lubricating axle sleeve (5), axle bed (6), the locking cushion block of eight prisms (7), split pin (8) and ring body (9).Double ring type rotating hoisting ring both ends are hanging ring, small in size, light-weight, it is easily installed connection, is able to bear compared with big load, the rotation of freedom and flexibility is capable of, eight prismatics are used inside hanging ring loosens cushion block, can bear larger to be torsion force, safety, high reliablity.
Description
Technical field
The utility model belongs to Lift-on/Lift-off System field, and the outer hangar system of specifically a kind of helicopter and Large-scale Hoisting system are used
Rotating hoisting ring.
Background technique
Country's rotating hoisting ring is used for angled special lifting occasion at present, and generally rotating hoisting ring screw, one end are ring,
One end is bolt.Traditional rotating hoisting ring load is smaller, and installs connection request height, and after long-time service, lifting bolt can be gradually
It loosens, it is necessary to re-define torque and tighten again, safety, reliability are lower.
Summary of the invention
The purpose of this utility model is to provide a kind of double ring type rotating hoisting rings.
Realize the utility model aim technical solution are as follows: a kind of double ring type rotating hoisting ring, including collar, screw,
Lid, graphite self-lubricating axle sleeve, axle bed, the locking cushion block of eight prisms, split pin and ring body；
The shaft end head of collar is equipped with screw thread, and collar passes through lid, graphite self-lubricating axle sleeve is threadedly coupled with axle bed, axis
The axis of ring is equipped with step and is limited；There are two symmetrical planes for the shaft end head of collar, have a through-hole perpendicular to two planes
And the axis is passed through, the geomery of the locking cushion block interstitial hole of eight prisms is consistent with the geomery in shaft end head section of collar, axis
Seat one end is eight prism type holes, and geomery is consistent with the locking cushion block contour dimension of eight prisms；Collar connect and limits with axle bed
Afterwards, the locking cushion block of eight prisms is passed through into collar end and be embedded in eight prism holes of axle bed, then pass through collar end with split pin
Hole, realize the locking anticreep that is threadedly coupled with axle bed of collar；Lid and ring body are attached by screw.
Compared with prior art, remarkable advantage: (1) the utility model double ring type rotating hoisting ring is meeting the utility model
The weight and volume of itself is reduced while compared with big load.(2) double ring type rotating hoisting ring both ends are hanging ring, simplify installation
Connection type improves safety and reliability.
Detailed description of the invention
Fig. 1 be according to the utility model proposes double ring type rotating hoisting ring exploded view.
Fig. 2 be according to the utility model proposes double ring type rotating hoisting ring installation diagram.
Specific embodiment
The utility model double ring type rotating hoisting ring both ends are hanging ring, and material uses high-intensitive 0Cr17Ni4Cu4Nb,
It is able to bear compared with big load；Inside be equipped with graphite self-lubricating axle sleeve, hanging ring in the axial direction under tension when, still can from
By flexibly rotating；Using being threadedly coupled inside hanging ring, to prevent thread looseness, putting for eight prismatics is used in threaded end
Loose cushion block can bear larger to be torsion force, improve the safety and reliability of hanging ring.
The utility model is described in further detail with reference to the accompanying drawings of the specification.
The rotating hoisting ring mainly include collar 1, stop washer 2, screw 3, lid 4, graphite self-lubricating axle sleeve 5, axle bed 6,
The locking cushion block 7 of eight prisms, split pin 8 and ring body 9.
As shown in Figure 1, the shaft end head of collar 1 has screw thread, collar 1 passes through lid 4, graphite self-lubricating axle sleeve 5 and axle bed 6
It is threadedly coupled, there is step to be limited on the axis of collar 1；There are two symmetrical planes for the shaft end head of collar 1, have one to lead to
Hole is perpendicular to two planes and passes through axis, the shape in the shaft end head section of the geomery and collar 1 of locking 7 interstitial hole of cushion block of eight prisms
Shape size is consistent, and 6 one end of axle bed is eight prism type holes, and geomery is consistent with locking 7 contour dimension of cushion block of eight prisms, in collar
After 1 connect and limits with axle bed 6, the locking cushion block 7 of eight prisms is passed through into 1 end of collar and is embedded in eight prism holes of axle bed 6, then
The hole that 1 end of collar is passed through with split pin 8, has been achieved collar 1 with axle bed 6 and has been threadedly coupled locking, anticreep；Finally with 6
Lid 4 and ring body 9 are attached by a screw 3, and stop washer 2 is housed on each screw 3, prevent screw loosening.
For the rotating hoisting ring in addition to stop washer 2, graphite self-lubricating axle sleeve 5 and split pin 8, other is main stress zero
Part, material are all made of high-intensitive 0Cr17Ni4Cu4Nb, and by theoretical calculation, double ring type rotating hoisting ring maximum is able to bear
The load of 180kN.
In use process, the annular section of the collar 1 of rotating hoisting ring and ring body 9 by rope respectively with lifting appliance and by
Hoisting object is into connection, and when lifting appliance slings cargo, rope can generate torsion, and double ring type rotating hoisting ring can discharge lifting process
The torsion of middle generation does not allow the power of torsion to act on lifting appliance, lifting appliance is prevented to be damaged, and rotating hoisting ring was lifting by crane
In journey when stress, collar 1 is rotated relative to ring body 9, lid 4, and the power of collar 1 is acted on completely on lid 4, in collar 1 and lid
Between graphite self-lubricating axle sleeve 5 play the role of lubrication and abrasionproof.
