Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a centrifugal compressor partition bundle disassembly and assembly tool. Background Art

[0002] Multi-stage high-pressure vertical split compressors are also called barrel compressors, which are mainly composed of an outer barrel, a partition bundle, a support bearing group, and a thrust bearing group. The partition bundle consists of a rotor and partitions of various levels, which are assembled inside the outer barrel. When the unit is overhauled, the partition bundle must be pulled out of the outer barrel. Because the centrifuge is becoming larger and larger, the partition bundle is very heavy, and special tools must be used to pull it out to a certain suitable lifting position before it can be safely lifted out for the next step.

[0003] At present, the weight of the partition bundle of the unit can reach several tons, and the disassembly and assembly work during maintenance is very difficult. The existing screw-type disassembly and assembly tools have limited torque resistance and laborious operation when in use, which often results in low disassembly and installation efficiency. There is a lack of connection design between the main parts of the existing disassembly and assembly tools, and there is a lack of stability during the operation. In addition, the height adjustment of the existing tool bracket is mainly achieved by increasing or decreasing the thickness of the pad, and the height adjustment is difficult and the adjustment accuracy is not high.

[0004] Therefore, it is necessary to propose a centrifugal compressor partition bundle disassembly and assembly tool to overcome the defects of the prior art. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art and provides a centrifugal compressor partition bundle disassembly and assembly tool.

[0007] The cam is provided with a plurality of through holes at an upper end plate of the plurality of movable brackets, and the movable bracket is provided with a plurality of through holes at an upper end plate of the plurality of movable brackets.

[0008] Furthermore, the upper end plate of the base crossbeam is provided with two rows of positioning holes with equal spacing.

[0009] Furthermore, a slot is provided at the upper end of the base support frame, and a bolt is installed in each of the threaded holes on both sides of the bottom of the base support frame.

[0010] Furthermore, a card slot is provided at the bottom of the movable bracket, a fixing plate connected to the partition bundle is provided at one end of the movable bracket, a square through hole is opened in the fixing plate, an elevator is installed on the fixing plate, the elevator is composed of a height adjustment cover, an elevator height adjustment bolt, and a lifting column, a roller is installed at the bottom of the lifting column, the roller is installed on the bottom of the lifting column through a pin, and the height adjustment cover is connected to the fixing plate through the elevator height adjustment bolt.

[0011] The utility model discloses a centrifugal compressor partition bundle disassembly and assembly tool. By adjusting the adjusting bolts of the base support frame, the base and the compressor unit axis can be kept parallel, and the base height is adjustable. At the same time, the movable bracket and the base support frame are connected together by the card grooves of the movable bracket and the base support frame. The card grooves are rectangular and have a certain width, which ensures the stability of the structure and increases the overall stability of the tool. When in use, the hydraulic feed device can push the partition bundle installed thereon to move, replacing the screw, avoiding the problem that the screw can withstand limited torque and laborious operation.
