Description

Technical Field

[0001] The present invention belongs to the field of welding auxiliary facilities, specifically a welding construction device for building roof steel structures. Background Art

[0002] A building roof steel structure refers to a structural form that can bear and transfer loads, which is connected by steel plates and hot-rolled, cold-bent or welded profiles through bolt or welding connection methods. Typical components include main trusses, secondary beams, support systems, purlins, etc. The building roof steel structure system has comprehensive advantages such as light self-weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution, and is reasonably and widely used in the field of construction engineering.

[0003] With the diversification of building roof shapes, the angles between different two components in a building roof steel structure are also different. For example Figure 9 and Figure 10 As shown, a square to-be-welded component one and a square to-be-welded component two are connected together by welding. The to-be-welded surface of the welding component one is square. If the to-be-welded surface of the to-be-welded component one is fixed in a vertical plane, when the side surface of the to-be-welded component two is perpendicular to the to-be-welded surface of the to-be-welded component one, the angle between the side surface of the to-be-welded component two and the horizontal plane is 90° or a situation other than 90°.

[0004] Currently, when welding the to-be-welded component one and the to-be-welded component two in this situation, the operation is as follows: First, fix the to-be-welded component one on a horizontal support platform; then, use a combination of an angle gauge and a wedge-shaped pad for angle measurement and adjustment to make the position of the to-be-welded component two meet the requirements; then, temporarily fix the to-be-welded component two; finally, perform welding and weld seam detection. This operation has the following disadvantages:

[0005] Firstly, after the to-be-welded component one is fixed on the horizontal support platform, its position cannot be adjusted, and the operator needs to adjust the to-be-welded component two according to the welding position. It is not only necessary to adjust the angle of the to-be-welded component two to meet the requirements, but also necessary to adjust the to-be-welded component two to be centered with the to-be-welded component one. The adjustment is cumbersome and the adjustment efficiency is low.

[0006] Secondly, the angle adjustment is realized by padding the to-be-welded component two with a wedge-shaped pad, and the adjustment is inconvenient, resulting in low welding efficiency. Summary of the Invention

Detailed implementation mode

[0038] The present invention will be further described below in conjunction with the drawings and embodiments as follows:

[0039] In the present invention, terms such as "longitudinal", "lateral", "vertical", "upper", "vertical", "horizontal", "top", "bottom", "left" and "right" indicate the orientation or positional relationship based on the Figure 1 orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0040] The steel structure welding construction device for building roofs, as Figures 1 - 8 shown, includes a roller shaft 2, side baffles 1 and a driving device for driving the roller shaft 2 to rotate. Side baffles 1 are respectively arranged at both ends of the roller shaft 2, and a row of the roller shafts 2 arranged side by side are rotatably supported by the side baffles 1 at both ends. This row of roller shafts 2 arranged side by side is used to support the component to be welded, and the side baffles 1 at both ends can play a role in supporting the roller shafts 2 and connecting this row of roller shafts 2 together. The area of the roller shafts 2 between the left and right side baffles 1 is the roller shaft transportation interval. After the first component to be welded is placed on the roller shafts 2, it can be longitudinally transported to the designated position along the roller shaft transportation interval. In this embodiment, the longitudinal direction refers to the direction perpendicular to the vertical direction and the axial direction of the roller shaft. The axial direction of the roller shaft 2 is also the width direction of the roller shaft transportation interval; the longitudinal direction is also the length extension direction of the roller shaft transportation interval.

[0041] An adjusting plate 3 is arranged on the roller shaft 2. The adjusting plate 3 is vertically and movably arranged in the axial direction of the roller shaft 2 within the roller shaft transportation interval. During use, the first component to be welded is located between the adjusting plate 3 and the side baffle 1 on the opposite side of the adjusting plate 3, and a limit driving mechanism for driving the movement of the adjusting plate 3 and locking its position is provided; the adjusting plate 3 and the side baffle 1 on the opposite side cooperate to limit the first component to be welded, preventing the first component to be welded from skewing during the welding process and so on.

[0042] The setting of the adjusting plate 3 can limit the first component to be welded, improving the welding accuracy. Moreover, it can adjust the usable area of the roller shaft transportation interval according to the first component to be welded with different sizes, making the device more flexible during use and greatly increasing the practicality of the device.

[0043] Support columns 6 are respectively fixed at the relative positions at the tops of the side baffles 1 on both sides. The second adjusting column 5 is adjustably connected to the support column 6 in parallel with the roller shaft 2, that is, the second adjusting column 5 can be adjusted in position along the transverse direction, which is parallel to the direction of the roller shaft 2. A first connecting member 7 perpendicular to the second adjusting column 5 is connected to the inner end of the second adjusting column 5. Both ends of the first connecting member 7 are provided with second connecting members 8. The second connecting members 8 are perpendicular to the first connecting member 7 and are rotatably connected to the first connecting member 7 along the axial direction of the first connecting member 7; the second connecting members 8 on the two side baffles 1 are arranged oppositely to form a fixture for clamping the second welding component. The second connecting member 8 is located above the roller shaft transportation interval.

[0044] The second connecting member 8 on the left side baffle 1 and the second connecting member 8 on the right side baffle 1 tightly hold the second component to be welded together, realizing the clamping of the second component to be welded. The setting of the first connecting member 7 enables two sets of second connecting members 8 to be distributed on one side of the second connecting member 8 along the longitudinal direction, so as to perform two-location limiting on one side of the second connecting member 8 along the longitudinal direction, which is beneficial to improving the limiting reliability. The second connecting member 8 is perpendicular to the first connecting member 7, thus expanding the contact surface with the second component to be welded in the vertical direction. And the second connecting member 8 can be rotated along the axial direction of the first connecting member 7, so that the angle between the side surface of the second connecting member 8 and the horizontal plane is adjustable. In this way, the second component to be welded can be adjusted by rotating the second connecting member 8, making the second component to be welded perpendicular to the welding surface of the first component to be welded, and the angle between the side surface of the second component to be welded and the horizontal plane is adjustable.

[0045] During specific use, first rotate the second connecting member 8 along the axial direction of the first connecting member 7 until the required angle, and then move the second adjusting column 5 along the axial direction until the second connecting member 8 tightly holds the second component to be welded. Compared with the traditional pad adjustment, the angle adjustment is more convenient and feasible, and the angle adjustment is automatically realized while holding tightly, further saving the working procedures.

[0046] Moreover, the first component to be welded is supported on the driving roller shaft 2, and the first component to be welded can be driven by the driving roller shaft 2 to move longitudinally to adjust the position. And under the limitation of the adjusting plate 3, the position of the first component to be welded in the transverse direction is determined. By moving the second adjusting columns 5 on both the left and right sides transversely, the second component to be welded can be positioned at different positions transversely, that is, the adjustment of the second component to be welded in the transverse direction is realized. With the coordinated adjustment of both the first component to be welded and the second component to be welded, the centering of the welding position can be quickly and effectively realized, which is beneficial to improving the welding efficiency of the components.

[0047] Through holes are provided at the positions corresponding to the roller shafts 2 on the side baffle 1, and both ends of the roller shaft 2 are clamped in the through holes of the corresponding side baffle 1; a fixing seat is provided at the bottom end of the side baffle 1. The fixing seat can be used to be fixed on the ground or the support table, so as to fix the building roof steel structure welding construction device in a suitable position for convenient use.

[0048] The adjusting plate 3 can be suspended and installed above the roller shaft 2, so that there is a small gap between the bottom end of the adjusting plate 3 and the top surface of a row of roller shafts 2. This small gap can meet the rotation requirement of the roller shaft 2 and does not affect the adjusting plate 3 from limiting the first component to be welded. In this embodiment, through holes are provided at the positions corresponding to the roller shafts 2 on the adjusting plate 3, and the roller shaft 2 penetrates through the through holes of the adjusting plate 3. The adjusting plate 3 is sleeved on the roller shaft 2, and the roller shaft 2 can play a role in limiting the movement of the adjusting plate 3, and can avoid problems such as deviation and inclination. As Figure 4 shown, the driving mechanism includes a first adjusting column 4. The first adjusting column 4 passes through the left side baffle 1 and is detachably connected to the adjusting plate 3 inside. An elastic member 11 is sleeved on the first adjusting column 4, and the elastic member 11 is located between the adjusting plate 3 and the left side baffle 1. By pulling the first adjusting column 4 to the left, the adjusting plate 3 can be pulled closer to the left side baffle 1, increasing the distance between the adjusting plate 3 and the right side baffle 1, which is convenient for placing the first component to be welded between the adjusting plate 3 and the right side baffle 1; when the external force acting on the first adjusting column 4 is released, under the action of the elastic member 11, the adjusting plate 3 moves towards the right side baffle 1 until it contacts the first component to be welded. In this embodiment, the elastic member 11 is a spring. The first adjusting column 4 can be an adjusting bolt, and its end is threadedly connected to the adjusting plate 3. A nut can be arranged on the first adjusting column 4, and the nut is located on the left side of the left side baffle 1. The adjusting plate 3 can be prevented from moving to the right by screwing the nut against the left side baffle 1.

[0049] Preferably, the driving device includes a motor 9 and a transmission belt 10; a rotating shaft is fixed to the end of the roller shaft 2 protruding from the right side baffle 1, the transmission belt 10 is sleeved on the rotating shafts of a row of roller shafts 2 protruding from the right side baffle 1, and the motor 9 is connected to one of the rotating shafts through a speed reducer. The rotation of the motor 9 drives the roller shaft 2 and the transmission belt 10 connected thereto to rotate, and the transmission belt 10 drives the other roller shafts 2 to rotate. The motor 9 can be fixed to the right side baffle 1 by an extension block provided at the bottom.

[0050] The first connecting member 7 includes a first limiting rod 701 and a fixing block 702, the fixing block 702 is connected to the inner end of the second adjusting column 5, and the first limiting rod 701 is fixed to the fixing block 702;

[0051] A uniform distribution of strip teeth 704 is provided at both ends of the first limiting rod 701 along its axial direction; the second connecting member 8 includes a second limiting rod 801, and a tooth hole is provided in the middle of the second limiting rod 801; the tooth hole of the second limiting rod 801 is adapted to the strip teeth 704 of the first limiting rod 701; the strip teeth 704 of the first limiting rod 701 are detachably inserted into the tooth hole of the second limiting rod 801; and the second limiting rod 801 is limited by a plug block 705 detachably connected to the end of the first limiting rod 701.

[0052] During use, the second limiting rod 801 can be rotated around the first limiting rod 701 as needed. After the second limiting rod 801 is rotated to a required angle with respect to the vertical plane where the first limiting rod 701 is located, the second limiting rod 801 is sleeved on the strip teeth 704 of the first limiting rod 701, and the strip teeth 704 are engaged with the tooth hole for limiting. Then, the plug block 705 is installed to prevent the second limiting rod 801 from slipping off the first limiting rod 701. Then, the second adjusting column 5 is axially moved along the second adjusting column 5 to drive the second limiting rod 801 to contact the second steel structure member to be welded, so as to clamp the second steel structure member to be welded.

[0053] If the angle adjustment is carried out before the second limiting rod 801 is installed on the first limiting rod 701, the adjustment is inconvenient. In this embodiment, as Figure 6 and Figure 7As shown, the first limiting rod 701 is a round shaft, which includes a shaft body section in the middle and shaft head sections at both ends along its axial direction. There is a shaft shoulder between the shaft head section and the shaft body section; the strip teeth 704 are arranged on the side of the shaft head section away from the shaft shoulder, and an adjustment section 703 is formed axially between the strip teeth 704 and the shaft shoulder; a spring 803 is arranged at the inner end of the tooth hole of the second limiting rod 801, and the spring 803 is connected to the inner side surface of the second limiting rod 801; axially, the tooth hole of the second limiting rod 801 is movably matched with the strip teeth 704 of the first limiting rod 701; the spring 803 is tensioned between the shaft shoulder of the first limiting rod 701 and the second limiting rod 801; when the spring 803 is in the first compression state, the tooth hole of the second limiting rod 801 is centered with the adjustment section 703; when the spring 803 is in the second compression state, the tooth hole of the second limiting rod 801 meshes with the strip teeth 704.

[0054] Among them, the length of the spring 803 in the second compression state is longer than that in the first compression state. In the second compression state, it still exerts a thrust on the second limiting rod 801 to prevent the second limiting rod 801 from axially disengaging from the strip teeth 704.

[0055] During use, first, push the second limiting rod 801 along the axial direction of the first limiting rod 701 to the adjustment section 703; then, rotate the second limiting rod 801 around the axial direction of the first limiting rod 701 until the required angle; finally, release the second limiting rod 801, and under the action of the spring 803, the second limiting rod 801 moves to the strip teeth 704, and the tooth hole meshes with the strip teeth 704, thereby adjusting the included angle between the second limiting rod 801 and the vertical plane where the first limiting rod 701 is located.

[0056] Both ends of the second limiting rod 801 are fixedly connected with round rods 804, and a rotating shaft 802 is rotatably sleeved on the round rods 804. The rotating shaft 802 is rotatably sleeved on the round rods 804 and is in direct contact with the second component to be welded. When clamping the second component to be welded and moving the second component to be welded longitudinally, it can avoid scratching the surface of the second component to be welded.

[0057] This application is applicable to the welding between a square welding component one and a square component two to be welded, and the welding surface of the welding component one to be welded is square. When the welding surface of the welding component one to be welded is parallel to the vertical plane where the axis of the roller shaft 2 is located, there are the following three situations between the welding component one and the component two to be welded:

[0058] First, as Figure 9 shown, the side surface of the component two to be welded is perpendicular to the welding surface of the welding component one to be welded, and the included angle between the side surface of the component two to be welded and the horizontal plane is equal to 90°. In this case, adjusting the second limiting rod 801 to the vertical position can achieve the clamping and angle requirements of the component two to be welded.

[0059] Second, asFigure 10 As shown, the side surface of the second component to be welded is perpendicular to the surface to be welded of the first component to be welded, and the angle between the side surface of the second component to be welded and the horizontal plane is less than 90°. In this case, rotating the second limiting rod 801 to a required angle with the vertical direction can also achieve the clamping of the second component to be welded.

[0060] Thirdly, as Figure 11 As shown, the side surface of the second component to be welded is perpendicular to the horizontal plane and perpendicular to the surface to be welded of the first component to be welded, and the angle between the bottom surface of the second component to be welded and the horizontal plane is greater than 0°.

[0061] In order to be able to adjust the angle between the second welding component and the horizontal plane to adapt to the above-mentioned third case and improve the adaptability, as Figure 8 As shown, the second adjusting column 5 includes an inner adjusting column 501 and an outer adjusting column 502. The outer adjusting column 502 is in a cylindrical shape. The inner adjusting column 501 is inserted into the outer adjusting column 502. Its inner end is connected to the fixed block 702, and its outer end extends out of the outer adjusting column 502. The inner adjusting column 501 is movably matched with the outer adjusting column 502 around the axis, and a locking member 503 for locking the inner adjusting column 501 and the outer adjusting column 502 is provided.

[0062] During use, after driving the second limiting rod 801 to move along its axis by the outer adjusting column 502 until the second component to be welded is clamped, by synchronously rotating the inner adjusting columns 501 on both sides around the axis, the second component to be welded can be driven to flip around the axis of the inner adjusting column 501, so as to achieve the purpose of adjusting the angle between the second component to be welded and the horizontal plane. After adjusting to the required angle, the position between the inner adjusting column 501 and the outer adjusting column 502 is locked by the locking member 503 before welding operations can be carried out. A motor can be connected to the outer end of the inner adjusting column 501 to drive the inner adjusting column 501 to rotate.

[0063] The outer adjusting column 502 and the support column 6 can be slidably matched, and the distance between them is locked by a locking screw. In this embodiment, the outer adjusting column 502 is a threaded column with an external thread and a smooth hole in the inner cavity. The outer adjusting column 502 is threadedly connected to the support column 6; the locking member 503 is a tight-top screw. A threaded hole is provided on the side wall of the outer adjusting column 502 that penetrates radially to its inner cavity, and the tight-top screw is threadedly connected to the threaded hole and presses against the inner adjusting column 501.

[0064] The threaded connection between the outer adjusting column 502 and the support column 6 is convenient and reliable, and it is convenient to adjust the movement of the second limiting rod 801 through the outer adjusting column 502. It should be noted that during the process of rotating the outer adjusting column 502, the locking member 503 can be released, and the fixed block 702 can be temporarily locked by hand-held operations or the like to prevent the fixed block 702 from rotating with the outer adjusting column 502. After the outer adjusting column 502 rotates in place, the locking member 503 is tightened again.

[0065] The fixed block 702 and the inner adjusting column 501 can be an integral part. A shoulder is formed between the fixed block 702 and the inner adjusting column 501. The shoulder and the inner end face of the outer adjusting column 502 constitute a limit to prevent the fixed block 702 from axially moving along the outer adjusting column 502 into the cavity of the outer adjusting column 502. A bearing can be arranged between the inner adjusting column 501 and the outer adjusting column 502.

[0066] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
