Description

Fluid coupling removal tool

technical field

The utility model relates to the field of hydraulic couplers, in particular to a dismantling tool for a hydraulic coupler. the

Background technique

The torque-limiting hydraulic coupling is commonly used in the transmission device of coal mine underground transportation equipment. The coupling sleeve is supported on the reducer shaft, and the torque is transmitted through the flat key or spline. Because the coupling housing is made of cast aluminum, it cannot withstand strong prying or impact. When damage occurs and a new coupler needs to be replaced, due to the harsh underground environment of the coal mine, the reducer shaft and the coupler sleeve will be corroded or frictionally sintered after long-term use. Usually, the old coupler cannot be removed by using the disassembly screw. Damaged and disassembled, unable to repair and repair, not only causes certain economic losses, but more seriously delays normal production. the

Contents of the invention

In order to effectively solve the problem that the hydraulic coupling is difficult to disassemble, reduce the labor intensity in the disassembly process of the coupling, and improve the disassembly efficiency, the utility model provides a hydraulic coupling disassembly tool. the

The technical solution adopted by the utility model to solve the technical problem is: a hydraulic coupling disassembly tool, which is characterized in that it includes a manual pump 1, a hydraulic cylinder 2, and a high-pressure rubber hose and joint for connection. The hydraulic cylinder 2 is processed with The external thread is mated with the internal thread on the output shaft sleeve of the fluid coupling. The hydraulic cylinder 2 includes a cylinder bottom 6, a cylinder body 7, a piston rod 8, a connecting sleeve 9, a handle 5 is welded on the cylinder body 7, and one end of the cylinder body 7 is processed into four evenly distributed card slots e, and the other end is used with the connecting sleeve 9 Bolt connection, cylinder block 7 and cylinder bottom 6 threaded connections. The center of one end of the cylinder bottom 6 is processed with a threaded hole d, and the other end is processed with a groove b, and the groove b communicates with the threaded hole d with a light hole c. The connecting sleeve 9 is processed with external thread, which is connected with the internal thread on the output shaft sleeve of the hydraulic coupling. When disassembling the hydraulic coupling, insert the lever into the two symmetrical slots to screw the hydraulic cylinder into the output shaft sleeve of the hydraulic coupling. Operate the manual pump 1 to supply liquid, push the piston rod 8 of the hydraulic cylinder to withstand the reducer shaft 4, and continue to supply liquid until all the hydraulic couplings are withdrawn. the

The beneficial effects of the utility model are: the utility model solves the problem that the hydraulic coupler is difficult to disassemble using the traditional disassembly screw, makes up for the deficiency of the existing coupler disassembly tool, has a reasonable structure, is easy to operate, and can quickly and safely disassemble the coupler Down. the
