Embodiment 1

[0020] Embodiment 1 Assembly and disassembly of support bearings

[0021] Because the quality of the supporting bearing is relatively heavy, the weight of the balance weight is calculated according to the principle of leverage, and the relational formula of the principle of leverage is: F1L1=F2L2.

[0022] Support bearing weight: 45kg; moment arm on the support bearing side: L1 = 180mm.

[0023] Mass of the balance weight: 16.2kg; moment arm on the side of the balance weight: L2=500mm.

[0024] According to the principle of leverage, the support bearing and the balance weight are kept in balance. During the installation process, the staff gives a forward installation force for installation and adjustment.

Embodiment 2

[0025] Embodiment 2 Assembly and disassembly of the snap ring of the horizontal structure of the new type compressor

[0026] Due to the structural limitation of the space for the installation of the snap ring of the horizontal structure, the special tool of the present invention can be used to reach the position more conveniently and accurately during the installation process. As shown in the attached figure, install the snap ring of the horizontal structure, the suspension ring and the connection plate are in a vertical state in space, and the position of the armrest and the connection plate is the same, and they are installed in a vertical state with the suspension ring.

Embodiment 3

[0027] Embodiment 3 Assembly and disassembly of the fixed ring of the vertical structure of the new type compressor

[0028] Due to the structural limitation of space, the installation of the vertical fixed ring can use the special tool of the present invention to reach the position more conveniently and accurately during the installation process. As shown in the attached figure, install the fixed ring of the vertical structure, the ring and the connecting plate are horizontal in space, the position of the armrest and the connecting plate is vertical, and the connecting rod is rotated 90 degrees to install the ring, which is perpendicular to the ring Install.

Abstract

The invention discloses an assembling and disassembling tool for supporting a bearing or a clamping ring. The assembling and disassembling tool comprises fasteners such as a connecting plate, a supporting rod, a hanging ring, a balance block and a handrail which are connected to one another, and is characterized in that (1) through holes with different diameters are designed in the connecting plate, (2) the supporting rod is designed by adopting a circular steel pipe, (3) the sizes of lifting rings are different, so that the lifting rings with proper strength can be selected when parts with different weights are lifted; (4) a round groove is formed in the upper portion of the balance block and used for moving the balance block and increasing or reducing the distance of a force arm; and (5) a handrail is used for facilitating the installation by a worker, and the worker can accurately arrive at a specified position. Equidistant bolt holes are formed in the approximately middle positions of the supporting rod, and clamping groove structures are formed between the bolt holes of the supporting rod and the handrail, so that the position movement of the balance block is ensured.

Description

technical field [0001] The invention belongs to the technical field of devices for installing and dismounting heavy components and parts, and in particular relates to a tool and method for installing and dismounting support bearings and snap rings. Background technique [0002] When the centrifugal compressor is installed and used, no dismounting tool is required for the installation of the normal horizontal split and vertical split centrifugal compressor support bearings. This tool is used for the assembly and disassembly of the large centrifugal compressor support bearings. [0003] In the prior art, we have not found a dismounting tool used for the installation of heavy parts on the compressor and the new centrifugal compressor with snap ring structure. Through our retrieval to the State Intellectual Property Office website (http: / / www.sipo.gov.cn), also do not see the patent of the assembly and disassembly tool aspect of relevant support bearing or snap ring.
