Description

Technical Field

[0001] The utility model relates to the technical field of universal joint coupling installation, in particular to a tool for conveniently installing a universal joint coupling of a rolling mill. Background Art

[0002] The rough and medium rolling area of ​​the high-speed wire production line is composed of 14 horizontal and vertical alternating two-roller short stress rolling mills. After rough and medium rolling, the billet passes through the vertical looper for transition, and is then guided by the guide device into the cantilever rolling mill to continue the subsequent rolling.

[0003] The rolling mill train is mainly composed of motors, reducers, two-roll short stress rolling mills, universal joint couplings and other equipment. The universal joint coupling is located between the reducer and the two-roll short stress rolling mill. The main function of the universal joint coupling is to connect the reducer and the two-roll short stress rolling mill. When working, the output power of the reducer drives the two-roll short stress rolling mill to rotate through the universal joint coupling, thereby completing the wire rolling. The universal joint coupling is mainly composed of external gear flat sleeves, spherical external gear sleeves, internal spline sleeves, spline shafts and other components. The external gear flat sleeve is connected to the rolls of the two-roll short stress rolling mill. One end of the internal spline sleeve is fixedly connected to the output shaft of the reducer by bolts, and the other end is connected to the spline shaft through a spherical external gear sleeve, thereby completing the force transmission.

[0004] At present, during the use of the rolling mill, the universal coupling needs to be replaced regularly or after a fault occurs. When the inner spline sleeve of the universal joint coupling is replaced online, it is mainly connected to the output shaft of the reducer by manual lifting, and then the fixing bolts are tightened to complete the installation. However, due to the limitation of on-site space, only 2-3 people can be accommodated on-site to carry out the operation when replacing the inner spline sleeve. Because the inner spline sleeve weighs about 120kg, the endurance of the operator is tested at all times when lifting the inner spline sleeve to connect with the output shaft, and there is a risk of bumping and being hit, which increases the labor intensity and reduces the work efficiency.

[0005] So we propose a tool for facilitating the installation of a universal joint coupling of a rolling mill in order to solve the above-mentioned problems. Utility Model Content
