[0010] Technical effects and advantages of the present invention:

[0011] 1. The heavy hammer of the invention can drive the impact hammer to impact downward intermittently through the telescopic rod. The impact hammer first impacts the lifting plate, and the lifting plate drives the upper mold to descend through the second spring. The upper mold cooperates with the lower mold to cover the outer armor to the steel cable (because the outer armor has plasticity, only a small section of the outer armor between the upper mold and the lower mold and nearby will be covered on the steel cable), thereby realizing the covering of the outer armor.

[0012] 2. When the steel cable covered with the outer armor pushes the swing rod, it will cause the swing rod to rotate around the first threaded rod. At this time, the L-shaped slide bar will be driven to move right on the limit slide groove (with Figure 1As a reference), the L-shaped slide bar will move to the bottom of the impact hammer, and the impact hammer will descend and press on the L-shaped slide bar. As the L-shaped slide bar is pressed to the point where it cannot move left or right, and the swing arm is tilted to the right at this time, the vertical descent of the second threaded rod will press the swing arm to rotate, and the swing arm will separate from the steel cable. As the impact hammer presses on the L-shaped slide bar this time, the lifting plate will descend further, and the cutter will cut off the steel cable covered with the outer armor, completing the fixed-length cutting of the steel cable. After the cutting, the steel cable covered with the outer armor will automatically fall down because the swing arm has been separated from the steel cable, completing the fixed-length cutting of the steel cable and lowering the steel cable.

[0013] 3. On the one hand, the hollow guide block can limit the outer armor to prevent the outer armor from rotating, so that the outer armor joint is always facing the plasma arc welding gun. The welding oil in the welding oil tank can be pumped from the pipeline to the hollow guide block by the water pump. The sponge brush on the hollow guide block brushes the welding oil on the outer armor joint to improve the welding effect in the subsequent welding process. BRIEF DESCRIPTION OF THE DRAWINGS

The impact hammer 32 first impacts the lifting plate 14, and the lifting plate 14 drives the upper mold 13 to descend through the second spring 30. The upper mold 13 cooperates with the lower mold 12 to cover the outer armor 19 onto the steel cable 20 (because the outer armor 19 has plasticity, only a small section of the outer armor 19 located between the upper mold 13 and the lower mold 12 and nearby will be covered on the steel cable 20), and the plasma arc welding gun 28 can weld the gap of the outer armor 19 covered on the steel cable 20.

When the steel cable 20 covering the outer armor 19 pushes the swing rod 7, the swing rod 7 will rotate around the first threaded rod 21, and at this time the L-shaped slide bar 9 will be driven to move rightward on the limiting slide groove 43 (with Figure 1 As a reference), the L-shaped slide bar 9 will move to the bottom of the impact hammer 32. At this time, the impact hammer 32 will descend and press on the L-shaped slide bar 9. Since the L-shaped slide bar 9 is pressed to the point where it cannot move left or right, and the swing bar 7 is tilted to the right at this time, the vertical descent of the second threaded rod 23 will press the swing bar 7 to rotate. At this time, the swing bar 7 will be separated from the steel cable 20. Since the impact hammer 32 presses on the L-shaped slide bar 9 this time, the lifting plate 14 will descend further, and the cutter 26 will cut off the steel cable 20 coated with the outer armor 19 to complete the fixed-length cutting of the steel cable 20.

The impact hammer 32 first impacts the lifting plate 14, and the lifting plate 14 drives the upper mold 13 to descend through the second spring 30 (at this time, the L-shaped slide bar 9 will follow the lifting plate 14 to descend, because the second threaded rod 23 can be in the track groove 22 The upper mold 13 cooperates with the lower mold 12 to cover the outer armor 19 onto the steel cable 20 (due to the plasticity of the outer armor 19, only a small section of the outer armor 19 between the upper mold 13 and the lower mold 12 and nearby will cover the steel cable 20), and then reset under the pulling force of the third spring 33, and the plasma arc welding gun 28 starts to weld the gap on the outer armor 19. When the steel cable 20 covering the outer armor 19 pushes the swing rod 7, the swing rod 7 will rotate around the first threaded rod 21. At this time, the L-shaped slide bar 9 will be driven to move right on the limiting slide groove 43 (to Figure 1 When the lifting plate 14 rises, under the elastic force of the first spring 6 and the limiting position of the limiting slide groove 43, the swing rod 7 will resume verticality with the ground, and the L-shaped slide bar 9 will be removed from under the impact hammer 32. The above operation can be repeated to complete the covering, welding and fixed-length cutting of the outer armor 19.
