[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0027] like Figure 1-Figure 7 As shown, a guardrail butt welding device includes: a cabinet body 1, a groove a11 is opened on the front side of the cabinet body 1, a movable guide rail 12 is fixedly connected to the top of the cabinet body 1, a welding robot 13 is provided on the movable guide rail 12, a support platform 14 is provided inside the groove a11, and a plurality of support blocks 15 are provided on the support platform 14; an adjusting component is provided inside the support platform 14, and is used to adjust the distance between the plurality of support blocks 15, a lifting component is provided inside the cabinet body 1, and docking components are respectively provided on the top of the cabinet body 1.

[0028] When in use, the vertical bars of the guardrail are placed on several support blocks 15 respectively. The distance between the several support blocks 15 can be adjusted through the adjustment component, so that different guardrail spacing requirements can be met. The cross bars of the guardrail are installed on the docking component respectively, and the two cross bars are aligned with the middle vertical bar through the docking component. After alignment, the joints are welded by the welding robot 13. The movable guide rail 12 can increase the range of movement of the welding robot 13. The placement height of the vertical bar can be adjusted through the lifting component to adapt to different guardrail docking requirements. Example 2

[0029] On the basis of Example 1, the adjustment component includes: a cross shear 2, a moving block 21, a moving groove 22, a driving motor a23, a bidirectional threaded screw 24 and a threaded block 25. A plurality of cross shears 2 are arranged inside the support platform 14. The opposite ends of the plurality of cross shears 2 are rotatably connected to each other. The tops of the plurality of cross shears 2 are rotatably connected to the moving blocks 21 near the center positions. A moving groove 22 is provided on the top of the support platform 14. The plurality of moving blocks 21 are respectively located inside the moving groove 22. A driving motor a23 is fixedly installed on one side of the support platform 14. One end of the driving shaft of the driving motor a23 is fixed. A bidirectional threaded screw 24 is fixedly connected, and the two external sections of the bidirectional threaded screw 24 are respectively threadedly connected to threaded blocks 25. The tops of the two threaded blocks 25 are connected to the bottoms of both ends of one of the cross shears 2. Through holes 26 are respectively provided on several moving blocks 21, and guide rods 27 are provided between several through holes 26. The opposite ends of the guide rods 27 are respectively connected to the opposite end of the inner wall of the moving groove 22. The bottoms of several support blocks 15 are respectively connected to the tops of several moving blocks 21. Grooves b28 are provided on the tops of several support blocks 15, and the bottoms of the grooves b28 are arranged in a triangular structure.

[0030] During processing, the vertical rods of the guardrail are placed on the grooves b28 respectively. The triangular structure of the bottom allows vertical rods of different diameters to be placed inside the grooves b28. The vertical rods are supported by the support blocks 15 for easy docking. When the distance between the vertical rods needs to be adjusted, the driving motor a23 is started to drive the bidirectional threaded screw 24 to rotate. When the bidirectional threaded screw 24 rotates, it is screwed with the two threaded blocks 25, thereby driving the two threaded blocks 25 to move in relative or opposite directions. When the threaded block 25 moves, it drives the connected cross shears 2 to cut or cut apart. When one of the cross shears 2 is cut together or cut apart, it drives The other cross shears 2 move together, and when the cross shears 2 move, the moving block 21 will be driven to move. Several moving blocks 21 move at the same time, and slide along the outside of the guide rod 27 to restrict the moving block 21, so as to prevent the moving block 21 from falling off from the inside of the moving groove 22. At the same time, the moving groove 22 also plays a role in restricting the moving block 21, so that the moving block 21 can only be translated along the horizontal direction of the moving groove 22. The driving motor a23 can rotate forward and reverse, and the function of adjusting the distance between the vertical rods can be realized by controlling the forward and reverse rotation of the driving motor a23, so as to adjust the distance between the vertical rods as required. Example 3

[0031] On the basis of Example 1, the lifting assembly includes: an installation cavity 3, a drive motor b31, a threaded rod 32, a support frame 33 and a base plate 34. Installation cavities 3 are respectively opened on the opposite sides of the groove a11. The drive motors b31 are respectively fixedly installed on the bottom of the two installation cavities 3. The tops of the two drive motors b31 are respectively driven and connected to the threaded rods 32. Support frames 33 are respectively provided inside the two installation cavities 3. The two support frames 33 are respectively threadedly connected to the outside of the two threaded rods 32. The tops of the two support frames 33 are respectively fixedly connected to the base plates 34. Through grooves 35 are respectively opened on the opposite sides of the two installation cavities 3. The two support frames 33 respectively penetrate the through grooves 35 and extend to the outside. The tops of the two base plates 34 are respectively connected to the bottom of the support platform 14.

[0032] When processing guardrails of different specifications, it is necessary to adjust the height of the support platform 14 first to ensure that the relative ends of the vertical rod can be accurately aligned with the center line position of the horizontal rod. At this time, the two drive motors b31 are started. After the two drive motors b31 are started, they rotate at the same time and in the same direction. The two drive motors b31 drive the two threaded rods 32 to screw with the two support frames 33. The two support frames 33 can only move in the vertical direction under the restrictions of the installation cavity 3 and the through groove 35. The two support frames 33 drive the base plate 34 to move, and the base plate 34 drives the support platform 14 to move. The two drive motors b31 are both forward and reverse motors that can rotate forward and reverse. The function of controlling the support platform 14 to rise or fall is achieved by controlling the rotation direction of the two drive motors b31. Example 4

[0033] On the basis of Example 1, the docking assembly includes: a pneumatic cylinder a4, a frame 41, a splint 42 and a pneumatic cylinder b43. Two symmetrically arranged pneumatic cylinders a4 are fixedly installed on the top of the cabinet 1. The two pneumatic cylinders a4 are fixedly connected to the frames 41 at opposite ends. The two frames 41 are respectively provided with splints 42. The two frames 41 are respectively provided with pneumatic cylinders b43 on the top. Rubber plates 44 are respectively provided at the bottom of the frame 41 and the bottom of the splint 42. Two guide grooves 45 are opened on the top of the cabinet 1. Limit blocks 46 are respectively provided inside the two guide grooves 45. The two limit blocks 46 are respectively connected to the bottoms of the two frames 41.

[0034] When docking the vertical bar with the horizontal bar, place the horizontal bar between the bottom of the frame 41 and the bottom of the clamping plate 42 respectively, and then start the pneumatic cylinder b43. After the pneumatic cylinder b43 is started, it pushes out and pushes the clamping plate 42 to clamp and fix the horizontal bar. The two rubber plates 44 can start the buffering function to avoid wear when the horizontal bar is clamped. Then start the two pneumatic cylinders a4. After the two pneumatic cylinders a4 are started, they push out and push the frame 41 to move relative to each other, so that the horizontal bar and the vertical bar can be docked.
