AI Technical Summary

Technical Problem

Existing technologies make it difficult to efficiently and safely remove tight-fitting wedge keys in large sand and gravel crushing equipment, especially short journal structures. Traditional tools are often inaccurate in positioning, may be pulled out at an angle, or may not be able to complete the removal, posing safety hazards.

Method used

The fixed connecting bracket is combined with the movable puller assembly. The positioning component is driven by the pull rod to move in the movable cavity, adjust the remaining space, adapt to different pull strokes, and achieve efficient removal of the wedge key.

Benefits of technology

In situations where structural space is limited, the wedge key can be fully pulled out, improving disassembly efficiency and safety. It is suitable for short journal structures and avoids the difficulties in adapting traditional tools and safety hazards.

Abstract

The application discloses a disassembling device for disassembling a wedge key of a crushing device, which comprises a connecting support fixedly arranged for being connected with the crushing device, and a puller assembly capable of moving relative to the connecting support. The puller assembly comprises a positioning member for holding the wedge key to be disassembled and a pull rod. The connecting support is provided with a movable cavity for accommodating the positioning member. The positioning member is movably arranged in the movable cavity. One end of the pull rod is movably arranged on the connecting support. At least one end of the pull rod extends into the movable cavity and is connected with the positioning member, so as to drive the positioning member to move in the movable cavity, adjust the remaining space in the movable cavity, adapt to different pulling strokes, and disassemble the wedge key.
