[0002] Civil engineering is a broad engineering field that involves the design, construction, maintenance, and management of various infrastructure projects, such as buildings, bridges, roads, tunnels, dams, airports, water supply, and sewage treatment systems. A large number of steel bar structures are used in civil engineering construction. However, the lengths of steel bars used in various engineering equipment are different. In order to be able to use the corresponding length connection device to connect the steel bars according to the length of the steel bars required by the engineering equipment, generally, an electric slag pressure welding device is used to connect the steel bars.

[0046] Embodiment 2:

[0047] Based on Embodiment 1, in this embodiment: The wiring assembly 3 includes a mounting bracket 301. A speed reducer 302 is fixedly connected to the upper part near the center of the rear end face of the mounting bracket 301. A servo motor 303 is fixedly connected to the rear end face of the speed reducer 302. The output end of the servo motor 303 is connected to the input end of the speed reducer 302. The output end of the speed reducer 302 penetrates through the rear end face of the mounting bracket 301 and reaches the inside of the mounting bracket 301, and a multi-stage conductive flower ring 308 is fixedly connected to the end. The fixed end of the multi-stage conductive flower ring 308 is fixedly connected to the mounting bracket 301. The rotating end of the multi-stage conductive flower ring 308 is connected to the output end of the speed reducer 302. The fixed end of the multi-stage conductive flower ring 308 is fixedly connected to a main connection wire 307. The main connection wire 307 penetrates through the front inner wall of the mounting bracket 301 and reaches the front end of the mounting bracket 301, and the end is connected to the programmable control box 4. The rotating end of the multi-stage conductive flower ring 308 is fixedly connected to a first connection branch wire 309, a second connection branch wire 310, a third connection branch wire 311 and a fourth connection branch wire 312. When the servo motor 303 is started, the servo motor 303 drives the speed reducer 302 to start. The speed reducer 302 drives the take-up reel 304 and the rotating end of the multi-stage conductive flower ring 308 to rotate, and winds the bushing 305 around the rotating end of the multi-stage conductive flower ring 308, which is convenient for taking up the wire and prevents the wire from being too long and easily getting entangled.

[0048] A bushing 305 is sleeved outside the first connecting branch wire 309, the second connecting branch wire 310, the third connecting branch wire 311 and the fourth connecting branch wire 312. The bushing 305 is wound around the rotating end of the multi-stage conductive flower ring 308. Winding reels 304 are fixedly connected to the rotating ends of the multi-stage conductive flower ring 308 at both the front and rear ends of the bushing 305. The first connecting branch wire 309 and the second connecting branch wire 310 are respectively connected to two micro servo motors 201. A spring connecting wire 306 is fixedly connected to the end of the fourth connecting branch wire 312. The other end of the spring connecting wire 306 is fixedly connected to a fifth connecting branch wire 313. The second electrode 812 is connected through the third connecting wire 311, and the first electrode 811 is connected through the fifth connecting wire 313, facilitating the energization. The first frame 1 and the second frame 7 are connected through the spring connecting wire 306, facilitating stretching along with the distance between the first frame 1 and the second frame 7, and preventing the spring connecting wire 306 from scattering.

[0049] Working principle: During use, the lower first clamp 810 is sleeved on the lower steel bar. Then, by rotating the lower slide bar 807, the slide bar 807 drives the shaft rod 805 to rotate, and the shaft rod 805 drives the threaded column 804 to rotate, so that the moving sleeve 802 moves along the base 801 to one side, pushing the second clamp 813 towards the first clamp 810 to clamp the lower steel bar. Then, the steel bar to be spliced is placed inside the upper first clamp 810 and butted against the lower steel bar. Rotate the upper slide bar 807, and the upper slide bar 807 drives the upper shaft rod 805 to rotate, thereby driving the upper threaded column 804 to rotate, so that the upper moving sleeve 802 moves along the base 801, pushing the upper second clamp 813 towards the upper first clamp 810 to clamp the spliced steel bar.

[0050] Then, the programmable control box 4 is used to control the energization of the third connecting branch wire 311 and the fourth connecting branch wire 312, so that heat is generated at the contact position of the two steel bars. Then, control the synchronous start of the two micro servo motors 201. The two micro servo motors 201 synchronously drive the two worm gears 206 to rotate. The two worm gears 206 drive the two worm wheels 207 to rotate synchronously. The two worm wheels 207 drive the two rotating rods 208 to rotate, so that the two lead screws 209 are synchronous, and the second frame 7 moves downward. The generated pulling force squeezes the contact position of the two steel bars. Due to the relatively large resistance, the contact position softens, and the two steel bars are closely attached during the process of applying pressure.

[0051] When splicing is required in an inclined position, one of the micro servo motors 201 is controlled to start. One of the micro servo motors 201 drives one of the worm gears 206 to rotate, causing one of the lead screws 209 to rotate. The two first rotating shafts 203 and the two second rotating shafts 204 rotate as the first frame 1 and the second frame 7 rotate. After adjusting to the appropriate position, clamping is performed. After clamping, the two micro servo motors 201 are synchronously controlled to start, so that the first frame 1 and the second frame 7 are displaced relative to each other for extrusion welding.

[0052] During use, the first frame 1 and the second frame 7 are connected by a spring connecting wire 306, which is convenient for stretching as the distance between the first frame 1 and the second frame 7 changes, and the spring connecting wire 306 will not scatter. Then, multiple wire bundling structures 9 are used to limit the first connecting branch wire 309, the second connecting branch wire 310, the third connecting branch wire 311, the fourth connecting branch wire 312, and the fifth connecting branch wire 313. The fifth connecting branch wire 313 and the third connecting branch wire 311 are respectively connected to the first electrode 811 and the second electrode 812, reducing the use of external wires and facilitating operation. After use, the servo motor 303 is controlled to start. The servo motor 303 drives the speed reducer 302 to start, and the speed reducer 302 drives the rotating ends of the take-up reel 304 and the multi-stage conductive flower ring 308 to rotate, winding the bushing 305 around the rotating end of the multi-stage conductive flower ring 308 for convenient wire collection and preventing the wires from being too long and easily getting entangled.

The scope of the present invention is defined by the appended claims and their equivalents.
