[0022] In the description of the utility model, it needs to be explained that, unless there is explicit provision and limitation, if the terms "arrange", "install", "connect" and "connect" appear, they should be understood broadly, for example, it can be fixed connection, it can also be detachable connection, or integral connection, it can be mechanical connection, it can also be electrical connection, it can be direct connection, it can also be indirect connection through intermediate medium, it can be the communication inside two elements, for ordinary skilled in the art, the above-mentioned terms can be understood in the specific meaning in the utility model according to specific circumstances.

[0023] The utility model will be described in detail below. Figures 1 to 3 The utility model will be described in detail below.

[0024] A kind of construction ground welding fume's recovery device, including body 1, the side of body 1 is connected with welding torch 101, body 1 side is provided with negative pressure device 2, the top of negative pressure device 2 is provided with connecting pipe 201, one end of connecting pipe 201 is provided with smoke pipe 202, the bottom of smoke pipe 202 is provided with ring around connecting block 2023, the side wall of welding torch 101 is provided with displacement ring groove 1011, smoke pipe 202 is connected with displacement ring groove 1011 by bottom ring around connecting block 2023 cooperation, the inside of smoke pipe 202 is provided with extension assembly, extension assembly is displaced along smoke pipe 202 inner wall.

[0025] Firstly, welding torch 101 connected to the side of body 1 is aligned to the area needing construction, then welding operation is carried out, while negative pressure device 2 is arranged on the top of body 1, smoke pipe 202 connected by connecting pipe 201 on the side of negative pressure device 2 is arranged on welding torch 101, so that suction force can be generated by smoke pipe 202 to absorb the smoke generated during welding when welding by welding torch 101, avoid too much smoke during welding, affect air quality, while avoid too much smoke being inhaled by construction personnel.

[0026] Further, displacement ring groove 1011 is the ring groove with the cross section of "T" shape, ring around connecting block 2023 also includes limiting block 2024, limiting block 2024 is trapezoidal block connected in the recess on the top of both sides of ring around connecting block 2023 by spring, the inner wall of displacement ring groove 1011 is provided with a plurality of recesses matched with limiting block 2024.

[0027] At the same time, the smoking pipe 202 can be moved to various positions of the side wall of the welding gun 101 by applying force to the entire smoking pipe 202, so that the smoking pipe 202 can be moved to various positions of the side wall of the welding gun 101, so as to cooperate with the welding gun 101 to extend into different narrow spaces. When the surrounding connecting block 2023 moves along the displacement ring groove 1011, the limiting blocks 2024 on the top of the two sides will be shrunk against the groove of the displacement ring groove 1011 due to the trapezoidal arrangement, until the smoking pipe 202 moves to the appropriate position, the limiting blocks 2024 will be popped out due to the spring, and then embedded into the groove in the inner wall of the displacement ring groove 1011, so as to limit the position of the smoking pipe 202 from moving by itself.

[0028] Further, the extension assembly comprises a strip-shaped opening 2021, a plug 2022, an extension pipe 203, a control rod 2031 and a limiting hole 2032. The strip-shaped opening 2021 is arranged on the top of the smoking pipe 202, the plug 2022 is connected to the top of the smoking pipe 202, the extension pipe 203 is connected to the inside of the smoking pipe 202, the control rod 2031 is arranged on the top of the extension pipe 203, and the limiting hole 2032 is arranged on the top of the extension pipe 203. The control rod 2031 is a rod body protruding from the top of the extension pipe 203 and penetrating through the strip-shaped opening 2021. The extension pipe 203 is a cylinder with an outer diameter matched with the inner diameter of the smoking pipe 202, and is made of a high-temperature resistant material. The limiting hole 2032 is a plurality of holes on the top of the extension pipe 203 matched with the plug 2022.

[0029] Finally, when the smoke is absorbed through the smoking pipe 202, the control rod 2031 protruding from the strip-shaped opening 2021 can be pushed by applying force to it, so that the extension pipe 203 connected to the inside of the smoking pipe 202 can be extended out to approach the welding position. Since the extension pipe 203 is made of a high-temperature resistant material, it will not be damaged by high temperature even when it approaches the welding position in time. When the extension pipe 203 is displaced, the plug 2022 is first removed, and then, after being moved to the appropriate position, it is penetrated through the smoking pipe 202 and matched with the corresponding limiting hole 2032 to limit the displacement distance of the extension pipe 203, so that it will not be moved during smoking.

[0030] The following is the embodiment of the utility model concrete process, first through the control body 1 one side connected welding torch 101 is aligned to the area that needs to be constructed, then welding operation is carried out to it, simultaneously, the negative pressure device 2 is arranged on the top of the body 1, the suction pipe 202 connected by the negative pressure device 2 one side connecting pipe 201 is arranged on the welding torch 101, so that when welding by welding torch 101, suction pipe 202 can produce suction to absorb the smoke generated during welding, avoid too much smoke during welding, affect the quality of air, at the same time, avoid being inhaled too much by the construction personnel, at the same time, the suction pipe 202 can be moved to each position of the side wall of welding torch 101 by applying force to the whole suction pipe 202, so as to cooperate with welding torch 101 to extend into different narrow spaces, and when the surrounding connecting block 2023 moves along the displacement ring groove 1011, the limiting block 2024 on both sides of the top will be shrunk because of the trapezoidal arrangement, until the suction pipe 202 moves to the appropriate position, the limiting block 2024 will be popped out because of the spring, and then embedded in the groove on the inner wall of the displacement ring groove 1011, so as to limit the position of the suction pipe 202, so that it will not displace itself, finally, when the smoke is absorbed by the suction pipe 202, the extension pipe 203 connected inside the suction pipe 202 can be extended out by controlling the control rod 2031 protruding from the bar-shaped opening 2021 to apply force to push it, so that it can be close to the welding position, and because the extension pipe 203 is made of high-temperature resistant material, it will not be damaged by high temperature when it is close to the welding position in time, and when the extension pipe 203 extends and displaces, the bolt 2022 will be removed first, and then after moving to the appropriate position, it is penetrated through the suction pipe 202 and matched with the corresponding limiting hole 2032 to limit the displacement distance of the extension pipe 203, so that it will not be driven when suction.
