Description

Technical Field

[0001] The utility model relates to the technical field of mine electric wheel seat bearings, and particularly relates to a seat bearing pulling device. Background Technique

[0002] Mine electric wheels are widely used in mine dump trucks. Mine dump trucks belong to off-road dump trucks and are used to transport coal mines and sand and gravel in off-road wild production areas, such as large open-pit mines and water conservancy projects. Due to advantages such as good mobility, fast turnover speed, and large load capacity, off-road mine dump trucks have become the main transportation tools for open-pit mine development and production.

[0003] In the related technology, after long-term use of mine electric wheels, the bearings on the seat will be worn, affecting work efficiency. To maintain or replace the bearings, the bearings need to be pulled out from the seat. Currently, slings or bearing pullers are usually used to pull out the bearings on the seat. However, when using a sling for pulling, the bearing will shake and collide with the seat, causing wear. And the bearing puller generally has a complex structure and requires manual assistance, resulting in a large labor intensity and low pulling efficiency. Therefore, there is an urgent need for a new seat bearing pulling device to meet the disassembly of the electric wheel seat bearings. Content of the Utility Model
