Description

Device for dismounting thrust collar

Technical Field

The utility model relates to a device, especially a tear device of pulling out distance head open belongs to mechanical equipment and makes technical field.

Background

The thrust bearing of the suspension type hydraulic generator is positioned on the upper frame and above the rotor. The thrust head is used for suspending the weight of the whole rotating part of the unit, and simultaneously, the axial water thrust of the water machine is borne. When the rotor or the rotating wheel needs to be lifted out during maintenance of the unit, the thrust collar needs to be pulled out firstly. The pulling method of the thrust collar is multiple, and the final purpose is to separate the large shaft from the thrust collar. The pulling difficulty depends on the tightness degree of the fit between the thrust collar and the large shaft, and when the thrust collar and the large shaft are in interference fit, the thrust collar is usually heated first to release the interference magnitude and then pulled.

At present, a jack is used more, but the jack has a dead stroke, synchronization is difficult to master, the problem that disassembly is difficult and the like due to too tight thrust heads is often caused, and inconvenience is caused for overhauling of a generator set.

SUMMERY OF THE UTILITY MODEL

For solving hydroelectric set and examining and repairing the in-process, cause work efficiency low, delay time limit for a project scheduling problem because of the distance head is difficult to tear open, the utility model provides a pull out device of generator distance head.

The technical scheme of the utility model is specifically as follows:

the utility model provides a tear device that pulls out thrusting head, includes the round backing plate, and the round backing plate is equipped with first round through-hole, and first round through-hole is equipped with second circle through-hole outward, and first round through-hole and big axle top bolt hole cooperation, second circle through-hole and thrusting head top bolt hole correspond.

Further, the round base plate is connected with the large shaft through a bolt.

Further, the round cushion plate is connected with the thrust head through a long screw.

Further, the device also comprises a jack, wherein the jack is arranged at the top of the thrust head, and when the device is used, the backing plate is symmetrically and uniformly jacked up, so that the clamping ring can be disassembled.

Further, the bolts or the long screws are symmetrically and synchronously disassembled, the nuts of the long screws are symmetrically screwed on the backing plate one by one, and the thrust heads are slowly pulled up to realize the disassembly.

Further, the thrust head is a suspension type hydraulic generator thrust head.

Compared with the prior art, the utility model has the advantages of it is following and effect:

the utility model has the advantages of being simple in structure and high in reliability, convenient operation compares and pulls out the power less with jack-up, but factor of safety is higher, has better solved because of the thrust collar tension brings dismantlement difficulty scheduling problem, provides convenience for generating set maintenance.

Detailed Description

The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive work based on the embodiments belong to the protection scope of the present invention.

Unless otherwise defined, technical or scientific terms used in the embodiments of the present application should have the ordinary meaning as understood by those having ordinary skill in the art. The use of "first," "second," and similar terms in the present embodiments does not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. "mounted," "connected," and "coupled" are to be construed broadly and may, for example, be fixedly coupled, detachably coupled, or integrally coupled; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. "Upper," "lower," "left," "right," "lateral," "vertical," and the like are used solely in relation to the orientation of the components in the figures, and these directional terms are relative terms that are used for descriptive and clarity purposes and that can vary accordingly depending on the orientation in which the components in the figures are placed.

As shown in fig. 1, the device for detaching and pulling the thrust collar of the suspension type hydraulic generator of the embodiment comprises a circular base plate 1, wherein the circular base plate 1 is provided with a first circle of through holes 2, the first circle of through holes 2 are externally provided with a second circle of through holes 3, the first circle of through holes 2 are matched with the bolt holes at the top of the large shaft, and the second circle of through holes 3 correspond to the bolt holes at the top of the thrust collar.

The round base plate 1 is connected with the large shaft 5 through bolts. The round cushion plate 1 is connected with a thrust collar 6 through a long screw rod 4. The device also comprises a jack which is arranged at the top of the thrust block, and when the device is used, the backing plate is symmetrically and uniformly jacked up, so that the clamping ring can be disassembled.

In this embodiment, the backing plate is a metal circular backing plate, and further comprises connecting pieces such as an attached stud bolt. A plurality of through holes are respectively processed on the inner ring and the outer ring of the backing plate, wherein the inner holes are matched with bolt holes at the top of the large shaft, and the backing plate can be connected with the large shaft through bolts. The outer hole corresponds to the bolt hole at the top of the thrust block, and the base plate can be connected with the thrust block through a long screw.

During the use, be connected backing plate and macroaxis top through the inner circle screw with the bolt, arrange the jack at the distance head top, the even jack-up circle backing plate 1 of symmetry to the snap ring can be dismantled down.

After the snap ring is disassembled and the thrust collar is heated, the base plate and the thrust collar are connected through the outer ring hole by the screw rod, the screw caps are screwed on the base plate, the screw caps are screwed up synchronously and symmetrically one by one, and the thrust collar is slowly pulled up through the jackscrews.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
