Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment preparation, and specifically relates to an air duct welding tool. Background Art

[0002] In the prior art, when making an air duct, the air duct to be welded is first placed on a welding table, and then a worker holds a welding tool and welds along the connection between the flange and the air duct. Since the working surface of a traditional welding table is fixed, the worker needs to walk around the welding table to weld all the gaps that need to be welded. Especially when the workload is large, this walking and welding working method will not only increase the physical burden of the workers, but also reduce work efficiency and affect economic benefits. Utility Model Content

[0003] In view of the problems raised by the background technology, the utility model designs a duct welding tool, the purpose of which is to provide a duct welding tool that saves time and labor and improves the welding efficiency of workers.

[0004] The technical solution of this utility model:

[0005] A duct welding tool comprises a base, a shaft and a platform. The upper end of the shaft is connected to the platform, and the shaft body is perpendicular to the bottom surface of the base and is connected to the base through a rotating device.

[0006] Preferably, the rotating device is a combination of a support bearing seat and a thrust bearing seat.

[0007] Preferably, the platform is detachably sleeved on the upper end of the shaft.

[0008] Preferably, a cylindrical sleeve is fixed to the middle bottom of the platform.

[0009] Preferably, the platform is a cross.

[0010] Preferably, the base comprises a base component 1 and a base component 2, the base component 2 is clamped inside the base component 1, and the side of the base component 2 away from the axis and close to the base component 1 is hinged to the middle part of the base component 1 through a hinge device.

[0011] Preferably, the length of the base component one is not less than half of the circumference of a side surface of the base component two, and the side surface is parallel to the long side of the base component one and perpendicular to the bottom surface.

[0012] Preferably, the base component 1 is rectangular, and the base component 2 is a cube.

[0013] Preferably, the hinge device connecting the base component 1 and the base component 2 is a rotating shaft.

[0014] The beneficial effects of the utility model are as follows: the utility model has a reasonable structure and a novel design. The middle bottom of the working platform is sleeved on the upper end of the shaft through a cylindrical sleeve, and the shaft and the base are connected through a rotating device, so that a rotational freedom of the platform is retained, so that when welding welding parts such as air ducts (equal diameter, variable diameter) on the platform, the worker stands in place and gently moves the platform with his hand, pushes the platform to the left or right, and the platform can rotate. The rotation of the platform drives the rotation of welding parts such as air ducts (equal diameter, variable diameter) on the platform, so as to realize the welding of welding parts, creatively eliminating the general process that workers need to weld while walking, reducing the physical burden of workers, and improving work efficiency and economic benefits; since the platform is detachably sleeved on the upper end of the shaft, the corresponding platform can be replaced according to different welding requirements (the diameters of the cylindrical sleeves fixedly connected to the bottom of different platforms are different), which greatly expands the scope of application of the present invention; by connecting the hinge device of the base assembly 2 and the base assembly 1, the position state of the workbench can be changed from horizontal to vertical, and the position state of the shaft can be changed from vertical to horizontal, which improves the ability of the utility model to cope with different work tasks.

[0020] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation method, structure, characteristics and effects of the utility model are described in detail as follows in conjunction with the accompanying drawings and preferred embodiments:

[0021] like Figure 1~2 As shown, a duct welding tool includes a base 1, a shaft 2, and a platform 3. The upper end of the shaft 2 is connected to the platform 3. The shaft body 2 is perpendicular to the bottom surface of the base 1 and is fixedly connected to the middle position of the side of the base 1 through a rotating device.

[0022] Preferably, the rotating device is a supporting bearing seat 22 and a thrust bearing seat 23 , and after the shaft 2 passes through the supporting bearing seat 22 and the thrust bearing seat 23 in sequence, the bottom of the shaft 2 is arranged in the thrust bearing seat 23 .

[0023] Preferably, the side surface of the base 1 is the right rear side surface.

[0024] Preferably, the platform 3 is a cross, and a cylindrical sleeve 4 is fixed to the middle bottom of the platform 3 . The cylindrical sleeve 4 is sleeved on the upper end of the shaft 2 , and the cylindrical sleeve 4 is limited by a limiting ring 5 on the outer side of the shaft 2 .

[0025] like Figure 4 As shown, the base 1 includes a base component 11 and a base component 12. The base component 12 is clamped inside the base component 11. The opposite side of the base component 12 away from the axis 2 and in contact with the base component 11 is hinged to the middle part of the base component 11 through a hinge device.

[0026] Preferably, the base component 1 11 is rectangular, and the base component 2 12 is a cube.

[0027] Preferably, the hinge device is a rotating shaft 13.

[0028] Preferably, the length of the base component 11 is not less than half of the circumference of a side surface of the base component 2 12 , and the side surface is parallel to the long side of the base component 11 and perpendicular to the bottom surface.

[0029] Specific use process:

[0030] 1. If Figure 3 As shown, firstly, a duct welding tool of the utility model is placed flat on the workplace, the platform 3 is sleeved on the upper end of the shaft 2 through the cylindrical sleeve 4 and is parallel to the bottom surface, and then the flange 6 and the duct end 7 that have been preliminarily spot-welded are placed on the platform 3, and then the welding tool (gas shielded welding or hand-held welding) is started to start the welding work of the duct to be welded (connecting seam, welding seam). At this time, the worker stands in place and gently moves the platform to the left or right with his hand, and the platform can rotate. The rotation of the platform drives the rotation of the welded parts such as the duct (equal diameter, variable diameter) on the platform to realize the welding of the welded parts. Therefore, the staff does not need to walk around the connecting seam (welding seam) of the flange 6 and the duct end 7, and only needs to stand in place to weld the entire connecting seam (welding seam).

[0031] 2. According to production needs, the utility model of a duct welding tool can be placed flat on the work site, and then the base assembly 11 is turned around the rotating shaft 13, and the shaft 2 is parallel to the bottom surface. Figure 4As shown, the mounting frame 6 and the detection inclined rod 9 are then installed in the middle position of the horizontal upper rod of the base assembly 2 12, and used as a circular thin plate roundness detection device for a fan impeller disk in patent number CN219284192U.

[0032] 3. The utility model retains a rotational freedom of the platform by sleeve-connecting the middle bottom of the working platform 3 to the upper end of the shaft 2 through a cylindrical sleeve 4, and connecting the shaft 2 and the base through a rotating device, so that when welding welding parts such as air ducts (variable diameter or constant diameter) on the platform 3, the worker stands in place and gently moves the platform with his hand, pushes the platform to the left or right, and the platform can rotate. The rotation of the platform drives the rotation of welding parts such as air ducts (equal diameter, variable diameter) on the platform, so as to realize the welding of welding parts, creatively eliminating the general process that workers need to weld while walking, reducing the physical burden of workers, and improving Work efficiency and economic benefits; since the platform 3 is detachably mounted on the upper end of the shaft 2, and the cylindrical sleeve 4 is limited by the limiting ring 5 on the outer side of the shaft 2, the corresponding platform 3 can be replaced according to different welding requirements (the diameters of the cylindrical sleeves 4 fixedly connected to the bottom of different platforms are different), which greatly expands the application scope of the utility model; by connecting the hinge device of the base component 2 12 and the base component 1 11, the position state of the workbench can be changed from horizontal to vertical, and the position state of the shaft 2 is changed from vertical to horizontal, which improves the ability of the utility model to cope with different work tasks and has a wide range of applications.
