Description

Technical Field

[0001] The utility model belongs to the technical field of coupling disassembly and assembly, and particularly relates to a large-thrust hydraulic coupling disassembly and assembly device. Background Art

[0002] At present, three-jaw pullers are often used in coupling mechanical maintenance to remove damaged bearings or equipment bearings along the axial direction. They can also be used as internal or external pullers. However, the commonly used three-jaw pullers are expensive, and the puller claws cannot withstand excessive push and pull forces and are easily damaged. They are unable to handle couplings or bearings that are too tight or have interference fits. If necessary, they need to be roasted with fire, which takes too long and increases the maintenance time.

[0003] For this reason, we propose a large-thrust hydraulic coupling disassembler to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a large-thrust hydraulic coupling disassembler, which uses a hydraulic jack to process a coupling with an interference fit, can give a large push-pull force, and can utilize its principle to pull the coupling off the bearing, thereby reducing the disassembly time, thereby disassembling the coupling and the bearing more quickly, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A large-thrust hydraulic coupling disassembler comprises a fixed seat, a disassembly mechanism located on the fixed seat, two protruding platforms are integrally welded on one side of the top wall of the fixed seat, the disassembly mechanism comprises an iron side plate abutting against the two protruding platforms, a hydraulic jack matched with the iron side plate, and a plate located on the other side of the top wall of the fixed seat, a through opening is formed at the center of the bottom wall of the iron side plate toward the inside thereof, a coupling to be disassembled is installed in the through opening, one end of the hydraulic jack is inserted into the center of the coupling and matched with the coupling;

[0007] Sleeves are fixedly welded on both sides of the plate, and threads are tapped in the two sleeves. Slide rods are threadedly installed in the two sleeves respectively. Two movable grooves are also formed on the iron side plate. The two slide rods pass through the two movable grooves respectively and are connected with positioning blocks. One side of the two slide rods can be limited to the plate through the two positioning blocks. Ear plates are welded on the opposite sides of the plate, and lead screws are threadedly installed on the two ear plates respectively. A mounting plate is rotatably connected to the bottom ends of the two lead screws, and the two mounting plates are welded to the other side of the top wall of the fixed seat.

[0008] As a preferred embodiment, the two movable grooves are symmetrical on both sides of the through-port, and the coupling is installed in the through-port; so that the coupling can be temporarily confined in the through-port, which facilitates the subsequent installation of a hydraulic jack in the center of the coupling for disassembly and separation of the coupling and the bearing.

[0009] As a preferred implementation scheme, positioning nuts are threadedly installed on the two sliding rods on the side of the plate facing away from the iron side plate, and the two positioning nuts are respectively abutted against the two sleeves; by screwing the two positioning nuts into the specified positions on the sliding rod, the sliding rod can be fixed to the plate, and the outer wall of the sliding rod is provided with an external thread.

[0010] As a preferred embodiment, two parallel connecting strips are provided between the two mounting plates, and two sides of the connecting strips are respectively welded to the two mounting plates; thus, the two mounting plates and the attached plates thereon and other structures are more stable.

[0011] As a preferred embodiment, a through hole is further provided on the top wall of the fixing seat below the iron side plate; wherein the through hole is used for the pipeline on the hydraulic jack to pass through.

[0012] In summary, the technical effects and advantages of the utility model are as follows:

[0013] The large-thrust hydraulic coupling disassembler and assembler fixes the coupling and the bearing thereon at the through-port, inserts one side of the hydraulic jack into the coupling, and abuts the other side against the plate to make the hydraulic jack work. When processing the coupling with interference fit, a large push-pull force can be applied, and the coupling can be pulled off the bearing by utilizing its principle, thereby reducing the disassembly time and thus disassembling the coupling and the bearing more quickly.
