Abstract
The fixed pulleys of the metallurgical crane comprise two fixed pulleys of the crane, the fixed pulleys of the crane comprise rotating shafts, a plurality of fixed pulleys are fixed on the rotating shafts, the axes of the rotating shafts of the fixed pulleys of the two cranes are coincident, the end part of a top shaft is fixed at the end part of one rotating shaft, and the other end part of the top shaft contacts with the end part of the other rotating shaft. The end of the rotating shaft is welded at the end of the top shaft. Compared with the prior art, the utility model has the technical effects that the top shaft is arranged between the central shafts of the two fixed pulleys, so that the central shafts of the two fixed pulleys are prevented from deviating towards the middle, and the abrasion of the steel wire rope and the fixed pulleys is not increased.
Description
Technical Field
The utility model relates to a fixed pulley combination of a metallurgical crane.
Background
The metallurgical crane is an indispensable equipment of steelworks, has the effect of lifting weight, and is busy in work and severe in environment, and in use, as shown in fig. 1, the central shafts of two fixed pulleys 10 and fixed pulleys thereof deviate towards the middle (see arrow direction in the figure), so that the abrasion of a steel wire rope and the fixed pulleys is increased, and accessories such as bearings, pulleys and the like are required to be replaced frequently, thereby influencing production and reducing production efficiency.
The problems are: how to prevent the central axes of the two crown blocks 10 from deviating towards the middle.
Disclosure of Invention
The utility model aims to solve the technical problems: how to design a fixed pulley combination of a metallurgical crane, and prevent the central axes of two fixed pulleys 10 from deviating towards the middle.
The technical scheme of the utility model is as follows:
the fixed pulleys of the metallurgical crane comprise two fixed pulleys of the crane, the fixed pulleys of the crane comprise rotating shafts, a plurality of fixed pulleys are fixed on the rotating shafts, the axes of the rotating shafts of the fixed pulleys of the two cranes are coincident, the end part of a top shaft is fixed at the end part of one rotating shaft, and the other end part of the top shaft contacts with the end part of the other rotating shaft.
The end of the rotating shaft is welded at the end of the top shaft.
Compared with the prior art, the utility model has the technical effects that the top shaft is arranged between the central shafts of the two fixed pulleys, so that the central shafts of the two fixed pulleys are prevented from deviating towards the middle, and the abrasion of the steel wire rope and the fixed pulleys is not increased.
Drawings
Fig. 1 is a schematic diagram of the prior art.
FIG. 2 is a schematic diagram of the present utility model.
Detailed Description
The utility model will be described in detail below with reference to the drawings and detailed description thereof.
Referring to fig. 2, a metallurgical crane fixed pulley assembly comprises two crane fixed pulleys 10, wherein the crane fixed pulleys 10 comprise rotating shafts 12, a plurality of fixed pulleys 13 are fixed on the rotating shafts 12, the axes of the rotating shafts 12 of the two crane fixed pulleys 10 are coincident, the end part of one rotating shaft 12 is fixed with the end part of a top shaft 11, and the other end part of the top shaft 11 is contacted with the end part of the other rotating shaft 12.
For the sake of firmness, the end of the shaft 12 is welded to the end of the top shaft 11.
The working principle is as follows:
because the top shaft is arranged between the central shafts of the two fixed pulleys, the top shaft can reduce and eliminate the axial force of the fixed pulley block of the crane, reduce the axial force born by the bearing of the fixed pulley block, improve the structural stress and prolong the service life of the bearing.
Meanwhile, the top shaft does not influence the work of the fixed pulley of the crane.
See the prior art for further content.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
