Multifunctional adjustable puller

Abstract

The invention discloses a multifunctional adjustable puller which comprises a drawing die beam, a drawing die bolt and a drawing die connecting piece, wherein a threaded hole matched with the drawing die bolt vertically penetrates through the middle part of the drawing die beam; the drawing die bolt penetrates through in the threaded hole; the two ends of the threaded hole penetrate through a mounting hole vertically respectively; in the length range of the mounting hole on the drawing die beam, multiple first positioning holes penetrate horizontally and are sequentially arranged at intervals; and the drawing die connecting piece is a drawing die hook or drawing die long screw. The multifunctional adjustable puller provided by the invention has a simple structure, is safe and convenient to assemble and use, is suitable for dismantling various parts of different specifications or parts of different devices, has high pulling efficiency and long service life and has small possibility of unhooking.

Description

technical field [0001] The invention relates to a puller, in particular to a multifunctional adjustable puller. Background technique [0002] Modern petrochemical enterprises, large electric power enterprises, super large coal mining enterprises, etc., cannot do without the couplings connecting the original motors and equipment for the moving equipment. When encountering regular maintenance of equipment, repairing faults, dismantling machinery and equipment, etc., first remove the half coupling on the equipment shaft, or the half coupling on the motor, some are called counter wheels, and some are called back wheels. According to the process and regulations of the maintenance operation of the moving equipment, the operator needs to be equipped with a puller to remove the half coupling from the original motor or other moving equipment. [0003] In the process of using the commonly used puller, once the puller hook hooks the half coupling to be removed and is stressed, the pul...

AI Technical Summary

Problems solved by technology

[0003] In the process of using the commonly used puller, once the puller hook hooks the half coupling to be removed and is stressed, the puller's puller is easily displaced laterally and slides out, making the disassembly of the half coupling The work of the device cannot continue

Therefore, in the prior art, it is necessary to use iron wires to bind the drag hook and the half-coupling, or to fix the drag hook and the half-coupling by heating and welding auxiliary measures, but the effect is not ideal

[0004] Secondly, the pullers used in the prior art do not have flexible adjustment functions, and cannot be applied to the disassembly work of various specifications or different equipment. As a result, it is necessary to equip different specifications of equipment with different specifications of pullers when working on site. Pulling out the tool leads to complicated operations and troublesome tool management

[0005] Finally, the puller in the prior art has a complex structure and many parts, which is not easy to carry and repair and maintain
