Specific embodiments

[0019] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0020] As Figures 1-4 shown, the present utility model provides a technical solution: a steel welding device with a protective function for construction engineering, including a workbench 1. Support rods 2 are arranged at the bottom of the workbench 1, and the support rods 2 are fixedly connected to the four corners of the bottom of the workbench 1. The protective plate 3 is inserted into the workbench 1, and the protective plate 3 is in a U - shape. The anti - detachment block 5, reinforcing rib 4, transparent window 9 and handrail 10 are all fixedly connected to the protective plate 3. The clamping device 11 and the transmission device 13 are both installed on the top of the workbench 1; the anti - detachment block 5 is used to limit the lifting distance of the protective plate 3, thereby preventing the protective plate 3 from being detached from the insertion with the workbench 1.

[0021] A limiting device 6 is arranged on the workbench 1. A cleaning brush plate 7, a clamping device 11 and a transmission device 13 are arranged on the top of the workbench 1. A protective plate 3 is arranged on the workbench 1, and reinforcing ribs 4, anti - detachment blocks 5 and handrails 10 are arranged on both sides of the protective plate 3. A transparent window 9 is arranged on the protective plate 3. A welding machine 12 is arranged on the transmission device 13, and the welding machine 12 is installed on the transmission device 13. The cleaning brush plate 7 is inserted into the workbench 1, and the cleaning brush plate 7 overlaps on both sides of the transparent window 9. A pull rod 8 is fixedly connected to the top of the cleaning brush plate 7; the protective plate 3 moves up and down, so that the cleaning brush plate 7 cleans the transparent window 9, facilitating the staff to better observe the welding situation of the workpiece.

[0022] Both ends of the cleaning brush plate 7 are provided with a pull rod 8 and a push rod 14. The push rod 14 is slidably connected in the workbench 1, and one end of the push rod 14 penetrates through the workbench 1 and is inserted into both ends of the cleaning brush plate 7. The connecting spring 15 is installed in the workbench 1, and one end of the connecting spring 15 is fixedly connected to the other end of the push rod 14. The elastic force of the connecting spring 15 is used to insert the push rod 14 into the cleaning brush plate 7, thereby assisting in fixing the cleaning brush plate 7 and greatly improving the stability of the cleaning brush plate 7.

[0023] A connecting spring 15 is arranged on the push rod 14. The limiting device 6 includes a handle 601. The handle 601 is fixedly connected to the cross bar 602. The connecting rods 603 are fixedly connected to both ends of the cross bar 602. The cross bar 602 and the connecting rods 603 are both inserted into the workbench 1. When the protection plate 3 rises, the arc surface of the clamping block 605 is squeezed, so that it shrinks into the workbench 1. Then when the protection plate 3 moves to the designated position, due to the elastic force of the limiting spring 604, the clamping block 605 is inserted into the protection plate 3 to facilitate fixing the height of the protection plate 3.

[0024] The handle 601 is provided with a cross bar 602, and both ends of the cross bar 602 are provided with connecting rods 603. One end of the connecting rod 603 penetrates through the limiting spring 604 and is fixedly connected to the clamping block 605.

The clamping block 605 is slidably connected in the workbench 1, and one end of the clamping block 605 penetrates through the workbench 1 and is inserted into the protection plate 3. The connecting rod 603 is provided with a limiting spring 604 and a clamping block 605. By pulling the handle 601 with the assistance of the cross bar 602 and the connecting rods 603, the clamping block 605 is shrunk into the workbench 1, so as to facilitate the subsequent removal of the welded workpiece.

[0025] The working principle of the present utility model is as follows: After the clamping device 11 clamps the workpiece, push the armrest 10 to make the protection plate 3 rise. When the protection plate 3 moves to the designated position, due to the elastic force of the limiting spring 604, the clamping block 605 is inserted into the protection plate 3 to prevent the sparks from splashing everywhere when the welding torch 12 welds the workpiece. Subsequently, pull the handle 601 with the cooperation of the cross bar 602 and the connecting rods 603 to make the clamping block 605 shrink into the workbench 1 to facilitate the subsequent reset of the protection plate 3. When the protection plate 3 resets, through the cooperation of the cleaning brush plate 7, the transparent window 9 is automatically cleaned. And through the cooperation of the push rod 14 and the connecting spring 15, the cleaning brush plate 7 is fixed, and the cleaning brush plate 7 is replaced by pulling the pull rod 8.
