The fixed-length mechanism, the pressing and cutting mechanism, and the conveying and coating mechanism are all fixedly connected to the bottom plate. The pressing and cutting mechanism includes four groups of second support legs, and the second support legs are fixedly connected to the bottom plate. The upper ends of the four groups of second support legs are fixedly connected with a top plate. Two groups of third springs are fixedly connected to the lower end of the top plate. A lifting plate is fixedly connected to the lower ends of the two groups of third springs. A cutter is fixedly connected to the lower end of the lifting plate. A limiting chute is fixedly connected to the upper end of the lifting plate. Multiple groups of second springs are fixedly connected to the lower end of the lifting plate. An upper mold is fixedly connected to the lower ends of the multiple groups of second springs. A limiting rod is fixedly connected to the upper end of the upper mold, and the lifting plate is slidably connected to the limiting rod. A lower mold is fixedly connected to the upper end of the bottom plate. An extension plate is fixedly connected to one side of a group of second support legs. A plasma arc welding gun is fixedly connected to one side of the extension plate.

[0005] In a preferred embodiment, the fixed-length mechanism includes a first support leg, and the first support leg is fixedly connected to the bottom plate. A first horizontal rod is fixedly connected to one side of the first support leg, and the first horizontal rod is fixedly connected to the second support leg. Multiple groups of first threaded holes are provided on the first horizontal rod. A first threaded rod is threadedly connected in the first threaded hole. A swing rod is rotatably connected to the first threaded rod. A track groove is provided on the swing rod. A limiting column is fixedly connected to one side of the first support leg. A first spring is sleeved on the limiting column. An L-shaped sliding rod is slidably buckled and connected to the limiting chute. Multiple groups of second threaded holes are provided on the L-shaped sliding rod. A second threaded rod is threadedly connected to a group of second threaded holes, and the second threaded rod slides in the track groove. The second threaded rod and the first threaded rod are in the same vertical plane.

[0006] In a preferred embodiment, the conveying and coating mechanism includes a mounting plate, on which an activity groove is provided. A lifting block is slidably connected in the activity groove. A lead screw is threadedly connected in the lifting block, and the lead screw is rotatably connected to the bottom end of the activity groove. The upper end of the lead screw is fixedly connected with a rotating rod, and one side of the lifting block is rotatably connected with an upper driving roller.

[0007] In a preferred embodiment, a welding oil tank is fixedly connected to one side of the mounting plate. A threaded cover is threadedly connected to the upper end of the welding oil tank. A hollow guiding block is fixedly connected to the side of the mounting plate opposite to the welding oil tank, and the hollow guiding block is communicated with the welding oil tank through a pipeline. A micro pump is arranged in the welding oil tank. Sponge brushes are arranged on the upper and lower sides of the hollow guiding block. Through holes are arranged on the upper and lower sides of the hollow guiding block. A motor is fixedly connected to one side of the mounting plate. One end of the motor extends to be provided with a motor shaft, and a lower driving roller is fixedly connected to one end of the motor shaft.

[0008] In a preferred embodiment, a weight is arranged on the upper end of the top plate. One end of the weight extends to be provided with a telescopic rod, and a hammer is fixedly connected to the lower end of the telescopic rod.

[0009] In a preferred embodiment, an outer armor is arranged between the lower die and the upper die. A steel cable is arranged in the outer armor, and the contact point on the left side of the outer armor and the steel cable is pre-fixed by spot welding.

[0010] The technical effects and advantages of the present invention:

[0011] 1. The weight of the invention can drive the hammer to intermittently impact downward through the telescopic rod. The hammer first impacts the lifting plate, and the lifting plate drives the upper die to descend through the second spring. The upper die and the lower die cooperate to wrap the outer armor onto the steel cable (since the outer armor is plastic, only the outer armor located between the upper die and the lower die and in a small section nearby will be wrapped onto the steel cable), realizing the wrapping of the outer armor.

[0012] 2. When the steel cable wrapped with the outer armor pushes the swing rod, the swing rod will rotate around the first threaded rod. At this time, the L-shaped sliding rod will be driven to move rightward on the limit sliding groove (to Figure 1Taking [a certain point] as the reference, the L-shaped slide bar will move to directly below the impact hammer. At this time, when the impact hammer descends, it will press on the L-shaped slide bar. Since the L-shaped slide bar is pressed and cannot move left or right, and at this time the swing rod is tilted to the right, the vertical descent of the second threaded rod will press the swing rod to rotate. At this time, the swing rod will separate from the steel cable. Since the impact hammer is pressing on the L-shaped slide bar at this time, the lifting plate will descend more, and the cutter will cut the steel cable wrapped with the outer armor, completing the fixed-length cutting of the steel cable. The cut steel cable wrapped with the outer armor will automatically fall because the swing rod and the steel cable have separated at this time, completing the fixed-length cutting of the steel cable and dropping the steel cable.

[0013] 3. On the one hand, the hollow guide block can limit the position of the outer armor to prevent the outer armor from rotating, so that the joint of the outer armor always faces the plasma arc welding gun. The welding oil in the welding tank can be pumped from the pipeline by the water pump to the hollow guide block, and the sponge brush on the hollow guide block brushes the welding oil on the joint of the outer armor, improving the welding effect in the subsequent welding process.

[0024] From Figure 1-8, the present invention provides a semi-automatic plasma arc welding machine for steel cable armor, which includes a bottom plate 1, a fixed-length mechanism 2, a pressing and cutting mechanism 3, and a conveying and coating mechanism 4. The fixed-length mechanism 2, the pressing and cutting mechanism 3, and the conveying and coating mechanism 4 are all fixedly connected to the bottom plate 1. The pressing and cutting mechanism 3 includes four groups of second support legs 11, and the second support legs 11 are fixedly connected to the bottom plate 1. The upper ends of the four groups of second support legs 11 are fixedly connected with a top plate 15. The lower end of the top plate 15 is fixedly connected with two groups of third springs 33. The lower ends of the two groups of third springs 33 are fixedly connected with a lifting plate 14. The lifting plate 14 is made of alloy steel. The lower end of the lifting plate 14 is fixedly connected with a cutter 26. The upper end of the lifting plate 14 is fixedly connected with a limit chute 43. The lower end of the lifting plate 14 is fixedly connected with multiple groups of second springs 30. The lower ends of the multiple groups of second springs 30 are fixedly connected with an upper die 13. The upper end of the upper die 13 is fixedly connected with a limit rod 29, and the lifting plate 14 is slidably connected with the limit rod 29. The upper end of the bottom plate 1 is fixedly connected with a lower die 12. One side of a group of second support legs 11 is fixedly connected with an extension plate 27. One side of the extension plate 27 is fixedly connected with a plasma arc welding gun 28; a weight 10 is arranged at the upper end of the top plate 15. The lower end of the weight 10 extends and is provided with a telescopic rod 31. The lower end of the telescopic rod 31 is fixedly connected with an impact hammer 32; an outer armor 19 is arranged between the lower die 12 and the upper die 13. A steel cable 20 is arranged inside the outer armor 19. The left contact point between the outer armor 19 and the steel cable 20 is pre-fixed by spot welding (used to drive the steel cable 20 to move together when the outer armor 19 is not pressed at the initial stage); the weight 10 can drive the impact hammer 32 to intermittently impact downward through the telescopic rod 31. The impact hammer 32 first impacts the lifting plate 14. The lifting plate 14 drives the upper die 13 to descend through the second springs 30. The upper die 13 and the lower die 12 cooperate to wrap the outer armor 19 around the steel cable 20 (since the outer armor 19 is plastic, only the outer armor 19 between the upper die 13 and the lower die 12 and in a small section nearby will be wrapped around the steel cable 20). The plasma arc welding gun 28 can weld the gap of the outer armor 19 wrapped around the steel cable 20.

[0025] The fixed-length mechanism 2 includes a first support leg 5, and the first support leg 5 is fixedly connected to the bottom plate 1. A first cross bar 8 is fixedly connected to one side of the first support leg 5, and the first cross bar 8 is fixedly connected to the second support leg 11. A plurality of first threaded holes 24 are provided on the first cross bar 8, and a first threaded rod 21 is threadedly connected to the first threaded holes 24. A swing rod 7 is rotatably connected to the first threaded rod 21. A track groove 22 is provided on the swing rod 7. A limit post 42 is fixedly connected to one side of the first support leg 5. A first spring 6 is sleeved on the limit post 42. An L-shaped slide bar 9 is slidably buckled on the limit chute 43. A plurality of second threaded holes 25 are provided on the L-shaped slide bar 9. A second threaded rod 23 is threadedly connected to a set of second threaded holes 25, and the second threaded rod 23 slides in the track groove 22. The second threaded rod 23 and the first threaded rod 21 are in the same vertical plane; when the swing rod 7 is not pushed, and the L-shaped slide bar 9 is driven to descend by the lifting plate 14, the second threaded rod 23 vertically descends in the track groove 22 and will not drive the swing rod 7 to rotate. 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 rightward on the limit chute 43 (taking Figure 1 as a reference). The L-shaped slide bar 9 will move to directly below the impact hammer 32. At this time, when the impact hammer 32 descends, it will press on the L-shaped slide bar 9. Since the L-shaped slide bar 9 is pressed and cannot move left and right, and at this time the swing rod 7 is inclined to the right, the vertical descent of the second threaded rod 23 will press and drive the swing rod 7 to rotate. At this time, the swing rod 7 will separate 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 more. The cutter 26 cuts off the steel cable 20 covering the outer armor 19, completing the fixed-length cutting of the steel cable 20. The steel cable 20 covered with the outer armor 19 after cutting will automatically fall because the swing rod 7 and the steel cable 20 have already separated at this time.

[0026] The conveying and coating mechanism 4 includes a mounting plate 16. An activity groove 36 is provided on the mounting plate 16. A lifting block 37 is slidably connected in the activity groove 36. A lead screw 35 is threadedly connected in the lifting block 37, and the lead screw 35 is rotatably connected to the bottom end of the activity groove 36. The upper end of the lead screw 35 is fixedly connected with a rotating rod 34. A driving roller 40 is rotatably connected to one side of the lifting block 37. A welding oil tank 18 is fixedly connected to one side of the mounting plate 16. A threaded cover 38 is threadedly connected to the upper end of the welding oil tank 18. A hollow guiding block 39 is fixedly connected to the side of the mounting plate 16 opposite to the welding oil tank 18, and the hollow guiding block 39 communicates with the welding oil tank 18 through a pipeline. A micro pump is arranged in the welding oil tank 18. Sponge brushes 44 are arranged on the upper and lower sides of the hollow guiding block 39. Through holes are arranged on the upper and lower sides of the hollow guiding block 39. A motor 17 is fixedly connected to one side of the mounting plate 16. One end of the motor 17 extends to be provided with a motor shaft, and one end of the motor shaft is fixedly connected with a driving roller 41. Rotating the rotating rod 34 can drive the lifting block 37 to descend through the lead screw 35, so that the driving roller 40 and the driving roller 41 cooperate to clamp the outer armor 19 to prevent the outer armor 19 from rotating. Starting the motor 17, the motor 17 drives the driving roller 41 to rotate counterclockwise through the motor shaft (taking Figure 1 as a reference), thereby driving the outer armor 19 to move towards the lower die 12. The welding oil in the welding oil tank 18 can be pumped from the pipeline by the water pump to the hollow guiding block 39. The sponge brush 44 on the hollow guiding block 39 brushes welding oil on the joint of the outer armor 19, improving the welding effect in the subsequent welding process.

[0027] This device is used for welding steel cable armor, and this device is located on the fixing frame ( Figure 8 ).

[0028] During specific work, when this device is used, first, according to the length of the steel cable armor to be cut, adjust the positions of the second threaded rod 23 and the first threaded rod 21 inserted into the second threaded hole 25 and the first threaded hole 24, and replace the first spring 6 with different lengths. Send the outer armor 19 and the steel cable 20 between the driving roller 40 and the driving roller 41, and ensure that the hollow guiding block 39 passes through the outer armor 19. Rotate the rotating rod 34, and the rotating rod 34 drives the lifting block 37 to descend through the lead screw 35, so that the driving roller 40 and the driving roller 41 cooperate to clamp the outer armor 19 to prevent the outer armor 19 from rotating. Starting the motor 17, the motor 17 drives the driving roller 41 to rotate counterclockwise through the motor shaft (taking Figure 1(taking [a certain state] as a reference), thereby driving the outer armor 19 to move downward towards the lower mold 12. The welding oil in the welding oil tank 18 can flow through the pipeline to the hollow guide block 39, and the sponge brush 44 on the hollow guide block 39 brushes the welding oil on the joint of the outer armor 19, improving the welding effect during the subsequent welding process. Start the heavy hammer 10. The heavy hammer 10 drives the impact hammer 32 to intermittently strike downward through the telescopic rod 31. The impact hammer 32 first strikes 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 sliding rod 9 will follow the lifting plate 14 to descend. Since the second threaded rod 23 can descend in the track groove 22, the swing rod 7 will not rotate). The upper mold 13 and the lower mold 12 cooperate to wrap the outer armor 19 around the steel cable 20 (due to the plasticity of the outer armor 19, only the outer armor 19 located between the upper mold 13 and the lower mold 12 and a small section nearby will be wrapped around the steel cable 20). Subsequently, it resets under the pulling force of the third spring 33. The plasma welding torch 28 is started to weld the gap on the outer armor 19. When the steel cable 20 wrapped with the outer armor 19 pushes the swing rod 7, it will cause the swing rod 7 to rotate around the first threaded rod 21. At this time, the L-shaped sliding rod 9 will be driven to move rightward on the limit sliding groove 43 (taking [a certain state] as a reference). Figure 1 (taking [a certain state] as a reference), the L-shaped sliding rod 9 will move to directly below the impact hammer 32. At this time, when the impact hammer 32 descends, it will press on the L-shaped sliding rod 9. Since the L-shaped sliding rod 9 is pressed and cannot move left and right, and at this time the swing rod 7 is tilted to the right, the vertical descent of the second threaded rod 23 will press and drive the swing rod 7 to rotate. At this time, the swing rod 7 will separate from the steel cable 20. Because the impact hammer 32 is pressing on the L-shaped sliding rod 9 this time, the lifting plate 14 will descend more. The cutter 26 cuts the steel cable 20 wrapped with the outer armor 19, completing the fixed-length cutting of the steel cable 20. After the steel cable 20 wrapped with the outer armor 19 is cut, it will automatically fall because the swing rod 7 and the steel cable 20 have already separated at this time. When the lifting plate 14 rises, under the elastic force of the first spring 6 and the limitation of the limit sliding groove 43, the swing rod 7 will return to be perpendicular to the ground again, and the L-shaped sliding rod 9 moves away from below the impact hammer 32. Repeating the above operations can complete the wrapping, welding, and fixed-length cutting of the outer armor 19.

[0029] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
