Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline welding equipment, and more specifically relates to a welding equipment revolving door and pipeline welding equipment. Background Art

[0002] Traditional pipe welding equipment does not have a protective gas door, or only has a hinged door. Without a protective gas door, the operator is prone to being burned by surrounding pipes. In addition, without a protective gas door, the weld will not receive effective gas protection, seriously affecting the quality of the welding. If a hinged door is used, a certain amount of operating space is required. Pipe welding equipment is very difficult to operate when the welding space is extremely narrow, and sometimes the welding gun cannot enter the welding area. In addition, in order to ensure the airtightness of the hinged door when closed, a sealing strip or a magnetic strip is installed between the two hinged doors. The structure is relatively complex, and at least two fingers are required to pry it open. Utility Model Content

[0003] In response to the problem that traditional pipeline welding equipment does not have a protective gas protection door or only has a hinged door, the purpose of the utility model is to provide a revolving door for welding equipment, which is movably arranged on the outside of the welding part of the welding equipment and is used to open or close the welding opening of the welding part when the welding equipment is performing welding operations; wherein, the revolving door is an arc-shaped sheet structure.

[0004] Furthermore, the revolving door includes: a door body, which is a tubular structure; a first opening, which is opened along the length direction of the door body; wherein the door body is rotatably covered on the outside of the welding equipment, and the width of the first opening is not less than the width of the welding opening.

[0005] Furthermore, the width of the first opening is smaller than the diameter of the tubular structure.

[0006] Furthermore, the present application provides a pipeline welding device, comprising: a welding part, a clamping part and any one of the rotating doors described above; the welding device comprises two of the clamping parts, the welding part is located between the two clamping parts, and a welding opening is provided; wherein, the rotating door is rotatably arranged between the two clamping parts.

[0007] Furthermore, the pipeline welding equipment also includes: a first rotation positioning portion, which cooperates with the rotating door and is used to prevent the rotating door from moving left and right relative to the welding portion when rotating.

[0008] Furthermore, the outer diameter of the welding portion is smaller than the outer diameter of the clamping portion, thereby forming an arc-shaped groove between the two clamping portions, and the revolving door is rotatably disposed in the arc-shaped groove.

[0009] Furthermore, the first rotation positioning portion is a limiting protrusion arranged on the outside of the two clamping portions.

[0010] Furthermore, the pipeline welding equipment also includes: a base; wherein the clamping part and the welding part are arranged on the base; a bent pipe positioning piece is arranged on the base and is located on the side of the clamping part away from the welding part, for positioning the bent pipe.

[0011] Furthermore, the bend pipe positioning member includes a bend pipe positioning support plate and a support plate locking member; wherein, the position of the bend pipe positioning support plate can be adjusted on the base to accommodate bends of different specifications; the support plate locking member is used to lock the bend pipe positioning support plate and the base after the position of the bend pipe positioning support plate is determined.

[0012] Furthermore, a guide rail is provided on the base, and the bend pipe positioning member also includes a slider, which is fixedly connected to one end of the bend pipe positioning plate away from the clamping portion. The slider can slide along the guide rail to guide the sliding of the bend pipe positioning plate.

[0013] The technical effects and advantages of this utility model are:

[0014] By rotatably positioning a curved, sheet-like revolving door outside the welding section of the welding equipment, the welding opening can be opened and closed with a single finger movement. Compared to traditional hinged doors, revolving doors are more convenient to operate and require less space. This reduces the operational complexity of pipe welding equipment in extremely confined spaces and improves welding efficiency. Furthermore, due to the revolving door's curved, sheet-like structure, shielding gas leaks between the two hinged doors are eliminated, resulting in a more airtight seal and improved welding results for pipe welding equipment using revolving doors.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0027] See also Figure 1 , which is a structural diagram of a revolving door for welding equipment provided by the present invention. Figures 1 to 9 The revolving door of the welding equipment is movably arranged on the outside of the welding part 20 of the welding equipment, and is used to open or close the welding opening of the welding part 20 when the welding equipment performs welding operations; wherein, the revolving door 10 is an arc-shaped sheet structure.

[0028] It can be understood that by rotatably positioning the arcuate sheet-like revolving door 10 outside the welding portion 20 of the welding equipment, the welding opening of the welding portion 20 can be opened and closed by simply rotating the revolving door 10 with a single finger. Compared to traditional hinged doors, the revolving door 10 is more convenient to operate and requires less operating space. This reduces the difficulty of operating pipe welding equipment in extremely narrow spaces and improves welding efficiency. Furthermore, due to the arcuate sheet-like structure of the revolving door 10, shielding gas leakage between the two hinged doors is eliminated. Pipe welding equipment using the revolving door 10 achieves a more airtight seal and better welding results.

[0029] Furthermore, the revolving door 10 includes: a door body 11, which is a tubular structure; a first opening 12, which is opened along the length direction of the door body 11; wherein, the door body 11 is rotatably covered on the outside of the welding equipment, and the width of the first opening 12 is not less than the width of the welding opening.

[0030] As will be appreciated, by configuring the door body 11 as a tubular structure, the door body 11 can be pivotally mounted outside the welding equipment, utilizing its inherent tubular structure. This eliminates the need for a pivoting connection structure, such as a hinge, between the revolving door 10 and the welding equipment. Providing a first opening 12 along the length of the door body 11, with a width no less than the width of the welding opening, ensures that the pipe to be welded can be smoothly loaded into the welding equipment through the welding opening. For example, the width of the first opening 12 can be the same as or greater than the width of the welding opening.

[0031] Furthermore, the width of the first opening 12 is smaller than the diameter of the tubular structure.

[0032] It can be understood that by setting the width of the first opening 12 to be smaller than the diameter of the tubular structure, it can be ensured that the cross-section of the revolving door 10 is an arc larger than half a circle. This can ensure that the revolving door 10 can rely on its own arc structure to be set on the outside of the welding equipment and will not fall off from the outside of the welding equipment.

[0033] Furthermore, the present application provides a pipeline welding device, comprising: a welding part 20, a clamping part 30 and any one of the revolving doors 10 described above; the welding device includes two of the clamping parts 30, the welding part 20 is located between the two clamping parts 30, and is provided with a welding opening; wherein, the revolving door 10 is rotatably arranged between the two clamping parts 30.

[0034] In one embodiment, two clamping portions 30 are used to clamp two sections of pipe to be welded. A welding portion 20, located between the two clamping portions 30, is equipped with a welding pin that can rotate around the joint of the pipes to be welded. The pipes to be welded are inserted into the welding portion 20 through a welding opening. Furthermore, the welding portion 20 is provided with a shielding gas outlet opening through which shielding gas can be discharged to enhance the welding effect. When the pipes to be welded are inserted into the welding portion 20 through the welding opening, the revolving door 10 is in the open position, and the welding opening is open. During welding, the operator can use a finger to rotate the revolving door 10, which closes the welding opening to prevent shielding gas from escaping from the welding opening during welding and affecting the welding effect.

[0035] Furthermore, the pipeline welding equipment further includes: a first rotation positioning portion, which cooperates with the revolving door 10 and is used to prevent the revolving door 10 from moving left and right relative to the welding portion 20 when rotating.

[0036] Furthermore, the outer diameter of the welding portion 20 is smaller than the outer diameter of the clamping portion 30 , thereby forming an arc-shaped groove between the two clamping portions 30 , and the revolving door 10 is rotatably disposed in the arc-shaped groove.

[0037] Furthermore, the first rotation positioning portion is a limiting protrusion provided on the outside of the two clamping portions 30 .

[0038] Furthermore, the pipe welding equipment also includes: a base 40; wherein the clamping part 30 and the welding part 20 are arranged on the base 40; a bent pipe positioning member 50, which is arranged on the base 40 and is located on the side of the clamping part 30 away from the welding part 20, for positioning the bent pipe.

[0039] It can be understood that by providing a bend positioning piece 50 for positioning the bend on one side of the clamping portion 30, when welding bends of the same specification, the operator only needs to align the welding needle with the weld during the first welding, and then adjust the bend positioning piece 50 to a position leaning against the bend. Then, subsequent bends of the same specification can be positioned according to the bend positioning piece 50, and the operator does not need to repeat the weld operation, thereby reducing the difficulty of operation for the operator and improving production efficiency.

[0040] For example, the pipes to be welded include pipe 1 and pipe 2, where pipe 1 is a bent pipe. After the weld seam and the tungsten needle are aligned, the clamping portion 30 clamps and secures pipe 1 and pipe 2. The elbow locator 50 is then adjusted to a position that abuts the elbow and supports it. Subsequent elbows of the same specification can use the elbow locator 50 to determine the alignment of the tungsten needle and the weld seam, eliminating the need to repeat the weld seam alignment process.

[0041] Furthermore, the elbow positioning member 50 includes an elbow positioning support plate 51 and a support plate locking member 52. The elbow positioning support plate 51 is adjustably mounted on the base 40 to accommodate elbows of varying sizes. The support plate locking member 52 is used to lock the elbow positioning support plate 51 to the base 40 after the position of the elbow positioning support plate 51 is determined. This prevents relative movement between the elbow positioning support plate 51 and the base 40, ensuring alignment of the weld seams of subsequent welded pipes. This prevents movement of the elbow positioning support plate 51, which could cause the weld seam to shift and affect welding quality.

[0042] For example, the base 40 is provided with multiple mounting positions for the elbow positioning plate 51, each corresponding to a different specification of the elbow to be welded. When the specification of the elbow to be welded changes, the plate locking member 52 is loosened to release the locking member 52 between the elbow positioning plate 51 and the base 40, and the position of the elbow positioning plate 51 is readjusted. After the position of the elbow positioning plate 51 is re-determined, the plate locking member 52 is tightened again to re-lock the elbow positioning plate 51 with the base 40.

[0043] Furthermore, a guide rail 61 is provided on the base 40, and the bend pipe positioning member 50 also includes a slider 62, which is fixedly connected to the end of the bend pipe positioning plate 51 away from the clamping portion 30. The slider 62 can slide along the guide rail 61 to guide the sliding of the bend pipe positioning plate 51.

[0044] It can be understood that compared with setting multiple mounting holes on the base 40, slidably setting the elbow positioning member 50 on the base 40 can improve the applicability of the welding equipment and meet different specifications rather than only meeting a few specific specifications of the pipes to be welded.

[0045] Furthermore, there are two guide rails 61, which are arranged in parallel on the base 40. Compared with only one guide rail 61, the provision of two parallel guide rails 61 can make the sliding of the slider 62 more stable.

[0046] In the description of the present invention, it should be understood that the indicated orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0047] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
