Technical Field
[0001] The utility model relates to the technical field of bearing equipment, in particular to a lifting device for a bearing box. Background Art
[0002] As the scale of the new energy vehicle industry continues to expand, new energy involves reducing the self-weight and increasing the endurance. The low density of aluminum alloy plates has a huge impact on the self-weight of the car. The aluminum alloy plates used in new energy vehicles are usually produced by hot rolling equipment. The assembly of the finishing work roll is an indispensable part of hot rolling production. Usually the finishing work roll is assembled on the bearing box. The bearing box, also known as the winch box, is a box part that supports and lubricates the bearing. At the same time, it bears the axial and radial forces generated by the equipment during operation.
[0003] When the finishing working rolls are being overhauled, the bearing box must be removed from the finishing working rolls and hoisted. The existing bearing box is hoisted by a lifting ring, and the lifting of the bearing box is achieved by matching the external thread of the lifting ring with the thread hole provided on the bearing box. However, after long-term use, the external thread of the lifting ring and the thread hole on the bearing box are prone to wear, which causes the lifting ring to fall off during the lifting of the bearing box, causing the bearing box to fall, which is very unsafe and affects the safety of personnel and the production process. In addition, it is time-consuming to install the lifting ring on the bearing box. Therefore, there is an urgent need for a lifting device for the bearing box to solve the above problems.
