Description

Technical Field

[0001] The invention relates to the field of special hoisting tools, in particular to a bar vertical rolling shaft hoisting tool, which is mainly used in the TGZ type telescopic drum gear coupling of the bar production line in the metallurgical production industry. Background Art

[0002] In the metallurgical production industry, TGZ telescopic drum gear couplings (commonly known as rolling mill couplings, telescopic shafts, etc.) are widely used. They are mainly used to connect the reducer and the rollers. They can transmit the motor torque to the rollers, thereby completing the extrusion of the rolled material. The advantages of this coupling are smooth transmission, low noise, ability to transmit large torque, large angular displacement compensation, long service life, and can be extended to a certain range (the height of the plant is limited). At present, 15 rolling mills in our factory's bar production line use this coupling (a total of 18). The rolling mill layout of our factory's bar production line adopts the alternating form of horizontal and vertical rolling mills, of which all 9 vertical rolling mills use TGZ telescopic drum gear couplings. Therefore, a hoisting tool suitable for hoisting the TGZ telescopic drum gear coupling is urgently needed. Summary of the invention

[0006] Furthermore, the upper end and the lower end of the auxiliary support are both welded and fixed.

[0007] Furthermore, the lower end of the counterweight is welded and fixed on the fixed base.

[0008] Furthermore, the lower end of the connecting shaft is welded or threadedly fixed to the fixed base.

[0009] Furthermore, the upper end of the connecting shaft serves as a movable hinge shaft of the movable clamp.

[0010] Furthermore, the handle end of the movable clamp is provided with three groups of wire rope grooves along its length direction.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] This tool improves replacement efficiency and avoids waste of spare parts caused by excessive maintenance.

[0013] Indirect economic benefits: It plays a positive role in improving employee work efficiency, optimizing personnel, and ensuring safe production. BRIEF DESCRIPTION OF THE DRAWINGS
