Description

Technical Field

[0001] The utility model belongs to the technical field of coupling unloading, in particular to a coupling unloading device. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. The two shafts rotate together during the transmission of motion and power and do not disengage under normal circumstances. It is sometimes used as a safety device to prevent the connected parts from being subjected to excessive loads and plays an overload protection role. In the steel industry, due to the large variety of large equipment and large transmission loads, the couplings are large in size. During inspection and maintenance operations, special equipment is required to disassemble the couplings.

[0003] A Chinese patent with the publication number CN218905220U discloses a coupling removal device, including a baffle, a pull rod, a jack, and a fixed seat; the jack is fixed on the fixed seat, the output end of the jack is connected to a shaft body, a coupling is arranged on the shaft body, a baffle is connected to the side of the coupling away from the jack, and the baffle is nested on the shaft body; the baffle and the fixed seat are connected by a pull rod, both left and right ends of the pull rod are provided with external threaded columns, the fixed seat and the baffle are provided with mounting holes, and locking nuts are threadedly installed on the external threaded columns. When the coupling needs to be removed, the baffle is first put on the shaft body and fits it tightly with the coupling, and then the two ends of the pull rod are respectively connected to the baffle and the fixed seat, and then the jack is aligned with the end of the shaft body, and then the jack is pressurized so that it can apply reverse pulling force to the coupling under the joint action of the fixed seat, the pull rod and the baffle, so as to achieve the purpose of pulling out the coupling.

[0004] The above-mentioned coupling extraction device still has some problems in use. The baffle of the device is U-shaped and fixed in size, and cannot be adjusted according to shafts of different diameters, which has great limitations. At the same time, the baffle of the U-shaped structure applies uneven force to the coupling when the coupling is pulled and disassembled, which may cause damage to the shaft and the coupling during the disassembly process. At the same time, the angle of the device cannot be adjusted according to the angle between the shaft and the coupling, and the scope of application is small. The above-mentioned coupling extraction device does not effectively solve these problems; therefore, a coupling extraction device is proposed to address the above problems. Utility Model Content
