Background technology
In repair enterprise, surpass 500Kg for weight, external diameter >=700mm, the propeller lock nut of length >=250mm is when mounted, utilize the steel wire rope of various dimensions and length to catch locking nut, carry out the operation of rotating nut after then using hoist crane to sling.In whole installation, in unloading process, except there is larger unsafe factor in the handling process, in assembling process, the locking nut just screwed in is because of the reason of himself weight, when screw thread just screws in several 2 ~ 3 tooth, specific pressure on the screw thread contact-making surface is very large, can reach the degree of conquassation distortion, produce larger frictional force and consequent frictional heat because of weight on contacted screw thread in the process screwed in, even can therefore make the locking nut and the tailing axle threaded metal that are in contact with one another that the fusion phenomenon occurs, form tearing of localized metallic, and then can make screw thread between the nut that screws in and propeller shaft the phenomenon of killing occur, have influence on the assembly quality of part, even may cause part injury, scrap.
The utility model content
The purpose of this utility model is to provide a kind of propeller lock nut attaching/detaching apparatus, this device result is simple, the scope of application is wide, solve the handling unsafe factor existed in the locking nut installation process and prevent thread damage in the nut rotary course, distortion and interlock, and the centering of nut and propeller shaft, adjustment.
In order to realize above purpose, the utility model is achieved through the following technical solutions:
A kind of propeller lock nut attaching/detaching apparatus, for the dismounting locking nut, be characterized in, comprises:
Horizontally disposed cross bar parts;
Be vertically set on flap shutter and the connecting plate at cross bar parts two ends;
The nut lock adjusting rod, the one end is horizontally set on flap shutter, and the other end extends the centre that is arranged on the cross bar parts;
Be positioned at the carrying roller of nut lock adjusting rod below, the one end is horizontally disposed with connecting plate, and its other end extends the centre that is arranged on the cross bar parts;
Described locking nut is movably arranged on carrying roller, and the one side is withstood the nut lock adjusting rod.
Described cross bar parts comprise crossbeam, slide and be nested with the main hoisting ring on crossbeam and adjust suspension ring respectively.
Described carrying roller outer ring is made as sleeve, and described sleeve is provided with parallel slot.
The parallel slot of described sleeve and locking nut internal thread are suitable.
The utility model compared with prior art, has the following advantages:
1, carrying roller adopts bathtub construction, to hold in the palm in locking nut easily, and, by this structure is carried out to force analysis and strength accounting, guarantees rigidity and the stability of this structure.
2, the main hoisting ring adopts the sliding sleeve form to be fixed on crossbeam, is convenient to tentatively adjust the center of gravity of handling process, thereby and with holding screw, actual hoisting point position is fixed the security reliability guaranteed in the handling process.
3, adjust suspension ring and equally also adopt sliding sleeve form and holding screw to be fixed on crossbeam, its effect is finely tuned the horizontal line of whole device, is convenient to the centering of locking nut and tailing axle and screws on the tailing axle screw thread.
4, carrying roller is for holding up locking nut; and the outer ring of carrying roller is the copper sleeve that can be exchanged; be processed into installed nut and there is identical pitch at the outer surface of sleeve; the parallel groove of the triangle of identical screw thread form; the good contact that contributes to carrying roller and big nut, more contribute to protect the screw thread of nut and reduce the distortion on carrying roller surface.The sleeve that only needs a small amount of different pitch of processing is just applicable to the locking nut of multiple different pitch and different-diameter.
5, the nut lock adjusting rod is mainly used in the antiskid effect of coming off in big nut handling process.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of propeller lock nut attaching/detaching apparatus of the utility model;
Fig. 2 is a kind of propeller lock nut attaching/detaching apparatus of the utility model application structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of propeller lock nut attaching/detaching apparatus, for dismounting locking nut 1, comprises: horizontally disposed cross bar parts; Be vertically set on flap shutter 3 and the connecting plate 4 at cross bar parts two ends; Nut lock adjusting rod 5, the one end is horizontally set on flap shutter 3, and the other end extends the centre that is arranged on the cross bar parts; Be positioned at the carrying roller 6 of nut lock adjusting rod 5 belows, the one end is horizontally disposed with connecting plate 4, and its other end extends the centre that is arranged on the cross bar parts; Described locking nut 1 is movably arranged on carrying roller 6, and the one side is withstood nut lock adjusting rod 5(referring to Fig. 2).
Described cross bar parts comprise crossbeam 21, slide and be nested with the main hoisting ring 22 on crossbeam 21 and adjust suspension ring 23 respectively.Described carrying roller 6 outer rings are made as the copper sleeve that can be exchanged, described sleeve is provided with parallel slot, the parallel slot of described sleeve and locking nut 1 internal thread are suitable, be processed into installed locking nut 1 and there is identical pitch at the outer surface of sleeve, the parallel groove of the triangle of identical screw thread form, the sleeve that therefore only needs a small amount of different pitch of processing is just applicable to the locking nut 1 of multiple different pitch and different-diameter.
As shown in Figure 2, in the handling process, steel wire penetrating main hoisting ring 22 and adjustment suspension ring 23, according to installed locking nut 1 size and center of gravity, adjust the position of main hoisting ring 22 and finely tuned with adjusting suspension ring 23, tangle locking nut 1 with carrying roller 6, and with the insurance adjusting rod, locking nut 1 is carried out to the insurance of antiskid.Because between carrying roller 6 and connecting plate 4, adopting rolling bearing, so when rotation lock nut 1, carrying roller 6 just and then rotates together, contribute to reduce the power of rotation lock nut 1, simultaneously owing in installation process, with this device, having held up locking nut 1, reduce locking nut and be pressed in the power on tailing axle external screw thread 7, so nut is in rotary course, the contact of internal and external threads reduces, and has reduced possibility, the frictional force between screw thread and the frictional heat produced therefrom and the probability of metal generation interlock of locking nut distortion.
In sum, a kind of propeller lock nut attaching/detaching apparatus of the utility model, this device result is simple, the scope of application is wide, solve the handling unsafe factor existed in the locking nut installation process and prevent thread damage in the nut rotary course, distortion and interlock, and the centering of nut and propeller shaft, adjustment.
