Description

Technical Field

[0001] The utility model relates to the technical field of electric shaft pulling, in particular to an adjustable electric shaft pulling mechanism. Background Art

[0002] The electric pneumatic puller is a disassembly tool for pneumatic components. It is powered by electricity to perform the extraction operation, which can effectively reduce the labor intensity of the staff, effectively avoid damage when pulling out the pneumatic components, and improve efficiency and safety. The electric pneumatic puller has the advantages of strong durability and easy maintenance. It can adapt to high-intensity use and provides support for the disassembly, assembly and maintenance of pneumatic components in fields such as industrial manufacturing and maintenance.

[0003] For example, the patent document with the announcement number CN218874348U records an automatic shaft puller for the pneumatic shaft of a rotary screen dryer. The entire shaft puller is supported by a base, the universal wheel improves the flexibility of the shaft puller, and the armrest can be used to conveniently push the shaft puller to move. The height of the first clamping plate and the second clamping plate can be adjusted according to the use requirements by rotating the threaded column. The second electric cylinder controls the first clamping plate and the second clamping plate to move closer or farther away from each other, and can clamp the pneumatic shaft. The clamp can prevent the first clamping plate and the second clamping plate from direct contact with the pneumatic shaft to avoid wear of the pneumatic shaft. When this automatic shaft puller for the pneumatic shaft of a rotary screen dryer pulls a smaller pneumatic shaft, it will cause the rod to fall off, slip, etc. due to the small clamping area, and its applicability is limited.

[0004] Based on this, an adjustable electric shaft pulling mechanism is now provided to eliminate the disadvantages of the existing device. Utility Model Content
