Description

Technical Field

[0001] The invention relates to the technical field of curtain wall frame welding, and in particular to a welding device for a steel structure frame of a building decorative curtain wall. Background Art

[0002] The building curtain wall is a building exterior protective structure or decorative structure, usually composed of panels and supporting structures, with multiple functions and characteristics. In actual use, it has the functional characteristics of architectural aesthetics, lighting and ventilation, energy conservation and environmental protection, and safety protection.

[0003] In actual use, the welding of the internal frame is particularly important, which affects the quality and safety of the entire curtain wall. In the conventional welding process, manual hand-held welding is usually used, which requires high skills and experience. In actual use, both the welding rod and the welding equipment need to be hand-held, and in the case of irregular welds, it is more likely to have an adverse effect on the welding quality. For this reason, we propose a welding device for the steel frame of a building decorative curtain wall. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a welding device for a steel frame of a building decorative curtain wall.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A building decorative curtain wall steel frame welding device, comprising: The connection mechanism is provided with two groups, the connection mechanism is provided with a detection component for detecting welding quality, and a track threading component for providing a lockable angle for welding, and the upper and lower parts of the connection mechanism are provided with an upper threaded sleeve and a lower threaded sleeve respectively; There are two sets of clamping mechanisms, which are installed on the upper threaded sleeves and the lower threaded sleeves on the two sets of connecting mechanisms to ensure the stability of the connection between the two sets of steel structures during the actual welding process; The slip ring mechanism is in the shape of a spliced ​​arc and is passed through the track passing component on the connecting mechanism. A welding mechanism is slidably arranged on the inner side of the slip ring mechanism to facilitate adjustment of the welding position during the welding process. A welding rod supply pipe is provided on the welding mechanism to ensure a stable supply of welding rods during the welding process, avoid shaking caused by manual supply of welding rods, and reduce the impact on welding quality.

[0006] As a preferred technical solution of the present application, the connection mechanism includes a fixed seat, and the lower threaded sleeve is rotatably arranged below the fixed seat to be connected to the clamping mechanism below; A spherical hinge is provided at the middle of the top of the fixing seat, a deflection plate is fixedly installed at the top of the spherical hinge, and an upper threaded sleeve is rotatably connected to the top of the deflection plate for connecting with a clamping mechanism located above; Several groups of detection components located on the outside of the spherical hinge are evenly installed on the top of the fixing seat, and the detection components include a supporting short rod. The bottom end of the supporting short rod is provided with a pressure sensor. The height of the supporting short rod is less than the height of the spherical hinge to ensure that when the upper threaded sleeve, the deflection plate and the fixing seat are in the same vertical state, the deflection plate will not press on the supporting short rod. When the welding quality is not strong enough, resulting in a certain degree of tilt of the upper frame, the upper threaded sleeve drives the deflection plate to tilt, squeezes the supporting short rod on the tilted side, and supports the deflection plate and the upper threaded sleeve under the action of the supporting short rod, ensuring the connection state while avoiding the deviation of the frame, and also effectively judges the tilt direction of the upper component with the help of the pressure sensor, and then judges the welding effect, which is convenient for repair welding.

[0007] As a preferred technical solution of the present application, an indicator light is provided on the upper outer side of the fixing seat, which corresponds one-to-one to the pressure sensor under the supporting short rod, thereby more conveniently providing a warning effect and facilitating the welding staff to detect and judge the welding quality.

[0008] As a preferred technical solution of the present application, the track threading assembly includes a connecting gear rotatably arranged on the side of the fixed seat, and the sides of the connecting gears close to each other are connected with a track threading arc plate for threading the slip ring mechanism; The fixing seat is provided with spring rods I on both sides of the connecting gear, and the spring rods I are connected with blocks meshing with the connecting gear, thereby ensuring that when no external force is applied, the angle of the connecting gear and the arc plate of the track connected thereto can be locked through the action of the spring rods I and the blocks, which facilitates the locking of the deflection angle of the slip ring mechanism as a whole and the welding mechanism during actual use, so that the welding mechanism can be stably adjusted according to the weld during the actual welding process, thereby ensuring the stability of the welding process.

[0009] As a preferred technical solution of the present application, the clamping mechanism includes two groups of semicircular sleeve ring pieces, and connecting ear pieces are provided at the joints of the sleeve ring pieces, and connecting bolts for locking are passed through the connecting ear pieces to ensure the overall stability of the sleeve ring pieces; A plurality of locking screws are threaded in an array on the sleeve ring piece, which are used to screw into the inner curtain wall frame for stable contact, so as to achieve stable connection and contact between the upper and lower frames during welding; The sides of the sleeve ring pieces are connected with L-shaped connecting bent rods. The outer side of the vertical section of the L-shaped connecting bent rod is provided with an external thread for threaded connection with the upper threaded sleeve or the lower threaded sleeve. It is used to adjust the actual size of the overall device, which is convenient for adjustment according to the actual welding situation and ensures stability during welding.

[0010] As a preferred technical solution of the present application, the slip ring mechanism includes a penetrating arc plate, which is in the shape of an arc and has an insertion block at one end, and an insertion groove matched with the insertion block at the other end of the penetrating arc plate, which facilitates stable connection during overall splicing. The penetrating arc plate is penetrated with two sets of interference screws at the insertion groove for locking connection with the insertion block, thereby further improving the overall stability of the slip ring mechanism after being spliced ​​into a ring.

[0011] As a preferred technical solution of the present application, a circular arc track is provided on the inner side of the arc plate, and the welding mechanism is slidably sleeved on the circular arc track. The ring formed by the slip ring mechanism can provide a circular sliding space for the welding mechanism, which is convenient for the actual welding process; The welding mechanism includes a sliding sleeve seat sleeved on the arc track, and a spring rod II is connected to one side of the sliding sleeve seat. Through the setting of the spring rod II, the welding mechanism and the frame are kept at a certain distance under normal conditions during the welding process, thereby reducing the occurrence of the phenomenon of false touch and ensuring the welding quality. The end of the spring rod II is connected to a connecting plate, and a welding head is fixedly connected to one side of the connecting plate to facilitate the stable progress of the welding process; A welding rod supply pipe inclined upward is fixedly installed at the lower part of the connecting plate. The welding rod supply pipe is in the shape of a hollow hole and is used for the insertion of the welding rod. The top outlet of the welding rod supply pipe is flush with the welding head end of the welding head, which is convenient for welding operations on the protruding welding rod. Two sets of elastic resistance rods are passed through the lower surface of the welding rod supply pipe to facilitate stable resistance to the inner welding rod, thereby ensuring the stable supply of welding rods during welding and reducing the occurrence of poor welding quality caused by human factors.

[0012] As a preferred technical solution of the present application, a holding ring is provided on one side of the top of the connecting plate to facilitate stretching of the overall welding mechanism during welding, thereby ensuring stable contact between the welding head and the welding rod inside the welding rod supply tube and the weld.

[0013] The beneficial effects of the present invention are: 1. Through the setting of the rail threading assembly on the slip ring mechanism and the welding mechanism in conjunction with the connection mechanism, the welding mechanism can effectively adapt to the welding requirements of irregular welds during the welding process, and cooperate with the setting of the rail threading assembly to effectively ensure the stability of the welding mechanism during the welding process; 2. By setting the detection components on the connecting mechanism, the welding quality monitoring of the upper welding frame during the welding process is effectively realized, and the deviation of the frame is effectively stopped, thereby improving the welding quality, effectively warning the welding personnel, and ensuring the stable progress of welding.

[0014] In summary, the present application can effectively meet the needs of the weld for adjustment during actual use, and during the welding process, effectively ensure the stability of the welding mechanism, improve the stability of the welding process, monitor the welding quality, and effectively prevent the skeleton displacement after welding. While ensuring safety, it can also warn the staff to facilitate the repair welding and reduce the safety hazards in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 8 , a building decorative curtain wall steel frame welding device, comprising: The connection mechanism 1 is provided with two groups. The connection mechanism 1 is provided with a detection component for detecting welding quality and a track threading component for providing a lockable angle for welding. The upper and lower parts of the connection mechanism 1 are provided with an upper threaded sleeve 13 and a lower threaded sleeve 17 respectively; The clamping mechanism 2 is provided with two groups and is installed on the upper threaded sleeve 13 and the lower threaded sleeve 17 on the two groups of connecting mechanisms 1 to ensure the stability of the connection between the two groups of steel structures during the actual welding process; The slip ring mechanism 3 is in the shape of a spliced ​​arc and is passed through the track passing assembly on the connecting mechanism 1. A welding mechanism 4 is slidably provided on the inner side of the slip ring mechanism 3 to facilitate adjustment of the welding position during the welding process. A welding rod supply pipe 45 is provided on the welding mechanism 4 to ensure a stable supply of welding rods during the welding process, avoid shaking caused by manual supply of welding rods, and reduce the impact on welding quality.

[0019] Reference Figure 2-Figure 3 The connection mechanism 1 includes a fixing seat 11, and a lower threaded sleeve 17 is rotatably disposed below the fixing seat 11 and is used to connect with the clamping mechanism 2 below; A spherical hinge 111 is provided at the middle of the top of the fixing seat 11, a deflection plate 12 is fixedly installed at the top of the spherical hinge 111, and an upper threaded sleeve 13 is rotatably connected to the top of the deflection plate 12 for connecting with the clamping mechanism 2 located above; Several groups of detection components located outside the spherical hinge 111 are evenly installed on the top of the fixing seat 11, and the detection components include a supporting short rod 15. The bottom end of the supporting short rod 15 is provided with a pressure sensor. The height of the supporting short rod 15 is less than the height of the spherical hinge 111, ensuring that when the upper threaded sleeve 13, the deflection plate 12 and the fixing seat 11 are in the same vertical state, the deflection plate 12 will not press on the supporting short rod 15. When the welding quality is not strong enough, resulting in a certain degree of tilting of the upper frame, the upper threaded sleeve 13 drives the deflection plate 12 to tilt, squeezing the supporting short rod 15 on the tilted side, and under the action of the supporting short rod 15, the deflection plate 12 and the upper threaded sleeve 13 are supported, ensuring the connection state while avoiding the deviation of the frame, and also effectively judging the tilt direction of the upper component with the help of the pressure sensor, and then judging the welding effect, which is convenient for repair welding.

[0020] An indicator light 14 corresponding to the pressure sensor below the supporting short rod 15 is provided on the upper outer side of the fixing seat 11, thereby providing a more convenient warning effect and facilitating the welding staff to detect and judge the welding quality.

[0021] Reference Figure 4-Figure 5 The track threading assembly includes a connecting gear 18 rotatably arranged on the side of the fixed seat 11, and the sides of the connecting gears 18 close to each other are connected with a track threading arc plate 16 for threading the slip ring mechanism 3; The fixing seat 11 is provided with spring rods Ⅰ19 on both sides of the connecting gear 18, and the spring rods Ⅰ19 are connected with blocks 110 meshing with the connecting gear 18, thereby ensuring that when no external force is applied, the angle of the connecting gear 18 and the track penetrating arc plate 16 connected thereto can be locked by the action of the spring rods Ⅰ19 and the blocks 110, which facilitates the locking of the deflection angle of the slip ring mechanism 3 as a whole and the welding mechanism 4 during actual use, so that the welding mechanism 4 can be stably adjusted according to the weld during the actual welding process, thereby ensuring the stability of the welding process.

[0022] Reference Figure 6 The clamping mechanism 2 includes two sets of semicircular sleeve ring pieces 21, and connecting ears are provided at the joints of the sleeve ring pieces 21, and connecting bolts 24 for locking are passed through the connecting ears to ensure the stability of the whole composed of the sleeve ring pieces 21; A plurality of locking screws 22 are threadedly arranged in an array on the sleeve ring 21, and are used to be screwed into the inner curtain wall frame for stable contact, so as to achieve stable connection and contact between the upper and lower frames during welding; The sides of the sleeve ring piece 21 are connected with L-shaped connecting bent rods 23. The outer side of the vertical section of the L-shaped connecting bent rod 23 is provided with external threads for threaded connection with the upper threaded sleeve 13 or the lower threaded sleeve 17, so as to adjust the actual size of the overall device, facilitate adjustment according to the actual welding situation, and ensure stability during welding.

[0023] Reference Figure 7 The slip ring mechanism 3 includes a penetrating arc plate 31, which is in an arc shape and has an insertion block 34 at one end. The other end of the penetrating arc plate 31 is provided with an insertion groove adapted to the insertion block 34, which is convenient for stable connection during overall splicing. The penetrating arc plate 31 is penetrated with two sets of abutment screws 33 at the insertion groove for locking connection with the insertion block 34, further improving the overall stability of the slip ring mechanism 3 after being spliced ​​into a ring.

[0024] Reference Figure 7-Figure 8 A circular arc track 32 is provided on the inner side of the arc plate 31, and the welding mechanism 4 is slidably sleeved on the circular arc track 32. The ring formed by the slip ring mechanism 3 can provide a circular sliding space for the welding mechanism 4, which is convenient for the actual welding process; The welding mechanism 4 includes a sliding sleeve 41 sleeved on the arc track 32, and a spring rod II 42 is connected to one side of the sliding sleeve 41. Through the setting of the spring rod II 42, the welding mechanism 4 and the frame are kept at a certain distance under normal conditions during the welding process, thereby reducing the occurrence of the phenomenon of false touch and ensuring the welding quality. The end of the spring rod II 42 is connected to a connecting plate 43, and a welding head 44 is fixedly connected to one side of the connecting plate 43 to facilitate the stable progress of the welding process; A welding rod supply pipe 45 is fixedly installed at the lower part of the connecting plate 43, which is inclined upward. The welding rod supply pipe 45 is in the shape of a hollow hole and is used for the insertion of the welding rod. The top outlet of the welding rod supply pipe 45 is flush with the welding head end of the welding head 44, which is convenient for welding operations on the protruding welding rod. Two groups of elastic resistance rods 46 are passed through the lower surface of the welding rod supply pipe 45 to facilitate stable resistance to the inner welding rod, thereby ensuring the stable supply of welding rods during welding and reducing the occurrence of poor welding quality due to human factors.

[0025] A holding ring 47 is provided on one side of the top of the connecting plate 43 to facilitate stretching of the overall welding mechanism 4 during welding, thereby ensuring that the welding head 44 and the welding rod inside the welding rod supply tube 45 are in stable contact with the weld.

[0026] Workflow: During the welding process, firstly, one set of clamping mechanisms 2 is clamped on the outside of the stable welding frame, and is clamped stably by the locking screw 22, and then the lower threaded sleeves 17 on the two sets of connecting mechanisms 1 are threadedly connected with the external threads of the vertical ends of the L-shaped connecting bent rods 23 on the clamping mechanisms 2 to ensure the stability of the foundation of the overall welding process; Then, another set of clamping mechanisms 2 is clamped on the outside of the frame to be welded, and is locked as described above, and then the L-shaped connecting bent rod 23 on the clamping mechanism 2 is threadedly connected to the upper threaded sleeve 13; Then, the welding head 44 can be moved to the weld seam through the sliding welding mechanism 4, and the welding rod supply pipe 45 and the elastic contact rod 46 are used to stably supply the welding rod to ensure the stability of the welding process. In this process, the slip ring mechanism 3 cooperates with the setting of the track threading assembly on the connecting mechanism 1 as a whole, so that the welding mechanism 4 can be carried out according to the needs during the welding process. The overall slip ring mechanism 3 is deflected with the two sets of connecting gears 18 as the axis line, thereby meeting the needs of irregular weld welding, and in this process, the self-locking function of the track threading assembly is used to effectively ensure the stability of the welding process; After welding is completed, the slip ring mechanism 3 and the welding mechanism 4 can be removed from the connecting mechanism 1 by using the abutment screws 33 on the slip ring mechanism 3; During the welding process, the welding quality is effectively detected through the detection component at the top of the connecting mechanism 1, as follows: when the welding quality is poor and the upper frame is offset, the upper frame is offset in the offset direction, and drives the upper threaded sleeve 13 and the deflection plate 12 to deflect, thereby compressing the supporting short rod 15 in the offset direction, and under the action of the supporting short rod 15, the continuation of the offset state is effectively stopped. In this process, since the supporting short rod 15 is compressed, the pressure sensor below it receives instructions, so that the indicator light 14 on the corresponding side gives a warning, thereby facilitating the welding personnel to make effective judgments, thereby facilitating the repair welding operation, ensuring the welding quality while stopping the offset during the frame welding process.
