Description

Technical Field

[0001] The invention belongs to the technical field of steel structure construction, and in particular relates to a steel structure construction welding device for assembled buildings. Background Art

[0002] Prefabricated buildings are buildings that are assembled from prefabricated components in factories, such as wall panels, beams, columns, and floor slabs, which are then transported to the construction site and assembled. They generally use a building skeleton composed of steel columns for support, giving the building advantages of high strength and lightweight. In some construction processes, welding is required between steel structures to ensure joint strength. Compared to ordinary bolt connections, welding can achieve seamless connections between steel structures, thereby preventing rust or corrosion at the joints. Before welding, the angles of the two welded steel structures need to be adjusted according to the process, which is generally pre-positioned by short welds. However, when the position of the steel structure is manually determined and short welds are performed, deviations between the two positions are inevitable, which will lead to a reduction in the stability of the subsequent connection with the prefabricated parts. Once the deviation is too large, it will not be able to pass the house inspection, and a large amount of manpower and financial resources will be required for rescue measures. Therefore, it is necessary to provide a steel structure construction welding device for prefabricated buildings. Summary of the Invention

The two inner walls of the slide are respectively hinged with a guide rod. The top of the guide rod is hinged with a driving disk movably mounted on the side of the gear 2. The side of the driving disk is inclined. The top of the guide rod is elastically connected to the slide through an elastic member 3. The bottom of the guide rod is hinged with a locking plate 3 movably mounted on the slide.

[0005] Preferably, the first gear movably passes through the top of the skateboard, and the second gear movably passes through the end of the extended board.

[0006] Preferably, a circular groove is provided on the side of the driving disk, an arc-shaped protrusion adapted to the groove is provided at the end of the locking plate 2, a notch adapted to the gear 2 is provided at the end of the locking plate 2, and a notch adapted to the gear 1 is provided at the end of the locking plate 3.

[0007] Preferably, the limiting component 1 includes a metal shell, an air storage box is installed on the outside of the metal shell, and a group of bellows connected to the air storage box are installed vertically and equidistantly on the inner wall of the metal shell. The inner wall of the metal shell is connected to the ball shafts of each bellows through a telescopic rod.

[0008] Preferably, the end of the bellows is in close contact with the outside of the first steel structure and is made of a flexible material, and the locking assembly is used to inject air into the air storage box.

[0009] Preferably, each group of the bellows and telescopic rods are arranged at equal angles in the circumferential direction on the inner wall of the metal shell, and a group of gas spring telescopic rods are respectively provided on both sides of each symmetrical group of bellows and telescopic rods. The gas spring telescopic rods are connected to the air storage box and one end of the telescopic part is installed with a steel ball, and the other end of the telescopic part of the gas spring telescopic rod on the same side is movably passed through the air storage box and is jointly connected with a metal plate.

[0010] Preferably, the locking assembly includes a protective box fixed to the side of the air storage box, the interior of the protective box is elastically connected to an adjustment plate through an elastic member 1, two pneumatic telescopic rods connected to the adjustment plate are symmetrically installed inside the protective box, a tooth plate 1 is installed on the outside of the protective box, a locking plate 1 is slidably installed on the outside of the adjustment plate, an elastic member 2 is provided on the adjustment plate to support the side of the locking plate 1, and a tooth plate 2 engaged with the tooth plate 1 is installed on the side of the locking plate 1.

[0011] Preferably, the two pneumatic telescopic rods are connected to the interior of the air storage box.

[0012] Preferably, the second limiting component includes a supporting plate hinged to the telescopic ends of two spring telescopic plates, and the two inner walls of the supporting plate are equidistantly hinged with a number of bogies, each of which is elastically connected to the supporting plate through an elastic member four, and the upper and lower ends of the bogie are respectively mounted with a bearing having a rubber wheel rolled on the side of the second steel structure.

[0013] Preferably, the second limiting component further includes two metal bars symmetrically mounted on the supporting plate, and the second steel structure is placed on the two metal bars.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention cooperates with the second steel structure by setting an adjustment component and a second steel structure structure to control the second steel structure to rotate around the first steel structure, the telescopic plate slides on the arc frame, the second steel structure is swung, and the slide plate rotates on the bracket to achieve another angle adjustment, and the two ends of the steel structure are moved up and down. It controls the change of the hinge angle of the extension plate and the slide plate through the second limit component and the spring telescopic plate. The second steel structure is manually pressed against the side of the steel structure, and the second limit component is slid, causing the two spring telescopic plates to be compressed and folded. The fixed end of the spring telescopic plate pushes the second locking plate to be close to the second gear through the guide plate. The extension plate is fixed on the slide plate, and the second locking plate pushes the driving disk to retract, and the top of the guide rod is displaced, and its bottom pushes the third end of the locking plate to be close to the first gear, so that the slide plate can no longer rotate, and the second steel structure is in a stationary state, thereby avoiding shaking of the second steel structure during the welding process.

[0015] The present invention cooperates with a limit component 1 and a steel structure 1, and injects air into the air storage box through the locking component. The air enters the bellows and forces the telescopic rod to extend. The end of the bellows is tightly attached to the side of the steel structure 1. The presence of the telescopic rod prevents the weight of the device from bending the bellows, which makes it impossible to fix. The two metal plates are pressed so that the telescopic end of the gas spring telescopic rod pushes the steel ball to roll on the steel structure 1. At this time, a part of the air inside the air storage box is extracted into the steel ball, and the bellows will no longer fit the outer periphery of the steel structure 1. The limit component 1 can slide on the outer periphery of the steel structure 1, thereby improving the flexibility of the device and improving the adjustability of the device. Since the steel ball and the gas spring telescopic rod are located on both sides of the steel structure 1, excessive displacement will not occur when the limit component 1 moves.

[0016] The present invention cooperates with the locking component and the limit component to push the locking plate to compress the elastic component. The tooth plate no longer contacts the tooth plate, and the adjustment plate is pressed down to allow the air in the pneumatic telescopic rod to enter the air storage box, thereby driving the limit component to enter the working state. Since air is compressible, when the device is subjected to external impact, the air inside the several bellows will flow through the air storage box, thereby reducing the impact force and preventing the outside of the steel structure from being damaged by the device. The device as a whole can also reduce the probability of being damaged by the impact force, further protecting the steel structure, and avoiding unnecessary material loss during the construction process.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 12 As shown, the present invention provides a welding device for steel structure construction for assembled buildings, comprising a steel structure 1 and a steel structure 2, and further comprising; A limiting component 3 provided on the outside of the steel structure 1; A locking component 4 installed outside the limiting component 3; An arc frame 5 welded to the top of the limit assembly 3; Sliding on the top of the arc frame 5 to adjust the component 6; The adjustment assembly 6 includes a telescopic plate 61 movably mounted on the top of the arc frame 5. The telescopic plate 61 has two telescopic ends and a bracket 62 is slidably mounted thereon. A slide plate 64 is rotatably mounted on the top of the bracket 62. A gear 1 63 is mounted on the top of the bracket 62. An extension plate 65 is hingedly connected to each of the two inner walls of the slide plate 64. A gear 2 69 is mounted on the hinged portion of the slide plate 64. A spring telescopic plate 66 is hingedly connected to the end of the extension plate 65. The telescopic ends of the two spring telescopic plates 66 are hinged together with a limiting component 2 7; The fixed end of the spring telescopic plate 66 is hinged to a locking plate 2 68 movably connected to the side of the extension plate 65 through a guide plate 67. The two inner walls of the slide plate 64 are respectively hinged to a guide rod 601. The top of the guide rod 601 is hinged to a driving disk 60 movably mounted on the side of the gear 2 69. The side of the driving disk 60 is inclined. The top of the guide rod 601 is elastically connected to the slide plate 64 through an elastic member 3 602. The bottom of the guide rod 601 is hinged to a locking plate 3 603 movably mounted on the slide plate 64.

[0021] Gear 1 63 moves through the top of the slide plate 64 , and gear 2 69 moves through the end of the extension plate 65 .

[0022] Adopting the above solution: preferentially controlling the limit component 1-3 to be fastened to the appropriate position on the steel structure 1 through the locking component 4; When the staff controls the steel structure 2 to rotate around the steel structure 1, the staff controls the telescopic plate 61 to slide on the arc frame 5 through the limit assembly 2 7, the spring telescopic plate 66, the extension plate 65, the slide plate 64 and the bracket 62; When the steel structure 2 is rotated to the appropriate position, the telescopic plate 61 can be manually pressed so that it can no longer slide on the arc frame 5. The steel structure 2 is swung, and the slide plate 64 can also be rotated on the bracket 62 to achieve another angle adjustment. By moving one end of the steel structure 2 up and down, the hinge angle of the extension plate 65 and the slide plate 64 is controlled by the limit assembly 2 7 and the spring expansion plate 66 to change, so that the angle between the steel structure 2 2 and the steel structure 1 1 can be further adjusted, thereby achieving the angle adjustment of the steel structure 2 2 in multiple directions, greatly improving the accuracy of the welding angle adjustment, and reducing the problem of subsequent steel structure 1 and steel structure 2 2 not being able to be well connected with the prefabricated components; When the angle adjustment between steel structure 1 and steel structure 2 is completed, manually press steel structure 2 against the side of steel structure 1 and slide limit assembly 2 7, causing the two spring expansion plates 66 to be compressed and folded. The fixed end of the spring expansion plate 66 pushes the locking plate 2 68 against the gear 2 69 through the guide plate 67. At this time, the extension plate 65 is fixed to the slide plate 64, and the angle of steel structure 2 can no longer be adjusted. The second locking plate 68 also pushes the driving plate 60 to retract into the second gear 69 through the inclined surface of the driving plate 60. The top of the guide rod 60 is displaced by the driving plate 60, and its bottom pushes the end of the third locking plate 603 to close to the first gear 63, so that the slide plate 64 can no longer rotate on the bracket 62, and the second steel structure 2 will also be in a static state, avoiding the shaking of the second steel structure 2 during the welding process, which may cause problems with the welding angle. At this time, the position of the steel structure 2 2 can only be rotated around the steel structure 1 1 by the arc frame 5. The worker needs to press one end of the steel structure 2 2 so that the other end is close to the outside of the steel structure 1 1. This will reduce the shaking of the steel structure 2 2 when it is welded, which will cause the problem of deviation in the welding angle. Furthermore, it also reduces the physical strength consumed by the worker to fix the steel structure 2 2. It should be noted that the telescopic plate 61 has two telescopic parts, which are located on both sides of the steel structure 2. When the structures on the bracket 62 are locked, that is, the steel structure 2 cannot be adjusted at an angle, this means that the welding work can begin. At this time, the sliding plate 64 is moved, which can simultaneously drive the bracket 62 to slide and the two telescopic ends on the telescopic plate 61. The telescopic plate 61 extends, which can make the structure on the bracket 62 away from the weld position of the steel structure 1 and the steel structure 2, thereby reserving sufficient working space.

[0023] like Figure 1-Figure 5 As shown, a circular groove is provided on the side of the driving disk 60, an arc-shaped protrusion adapted to the groove is provided at the end of the locking plate 2 68, a notch adapted to the gear 2 69 is provided at the end of the locking plate 2 68, and a notch adapted to the gear 1 63 is provided at the end of the locking plate 3 603.

[0024] The above solution is adopted: when the locking plate 2 68 pushes the driving disc 60 to retract into the gear 2 69 through the inclined surface of the driving disc 60, the arc-shaped protrusion on the side of the locking plate 2 68 will also be located in the circular notch. At this time, the elastic member 3 602 pushes the end of the guide rod 601 and forces the driving disc 60 to be close to the locking plate 2 68. If the guide rod 601 needs to return to its original position, the locking plate 2 68 needs to be separated from the driving disc 60. However, at this time, the driving disc 60 is stuck on the driving disc 60 and cannot be pushed and guided by the elastic force of the elastic member 3 602. The rod 601 and the driving disk 60 return to their original positions. Once the device locks the structure in the adjustment component 6, so that the steel structure 2 cannot be adjusted in angle, it is necessary to manually press the driving disk 60 so that it does not fit with the locking plate 2 68, and control the limit component 2 7 to return to its original position. The locking plate 2 68 will naturally separate from the driving disk 60. At this time, releasing the driving disk 60 can return the device to its original position, avoiding accidental touch during operation, which causes the welding angle to change and thus improves the stability of the device.

[0025] like Figure 1 、 Figure 6-Figure 8 As shown, the limit assembly 3 includes a metal shell 31, an air storage box 32 is installed on the outside of the metal shell 31, and a group of bellows 33 connected to the air storage box 32 are installed vertically and equidistantly on the inner wall of the metal shell 31. The inner wall of the metal shell 31 is connected to the ball shaft of each bellows 33 through a telescopic rod 34.

[0026] The end of the bellows 33 is in close contact with the exterior of the steel structure 1 and is made of a flexible material. The locking assembly 4 is used to inject air into the air storage box 32 .

[0027] The above solution is adopted: the position of the limit assembly 3 on the steel structure 1 is determined first, and air is injected into the air storage box 32 through the locking assembly 4. The air enters the bellows 33 and forces the telescopic rod 34 to extend. The end of the bellows 33 is closely attached to the side of the steel structure 1, and the metal shell 31 and all the structures thereon are fixed to the steel structure 1. The presence of the telescopic rod 34 prevents the weight of the device from compressing the bellows 33 and bending it, which would make it impossible to fix it. It should be noted that the flexible material of the side of the bellows 33 is not limited to a certain type, and the material needs to be used according to the actual situation. The flexible material will ensure that when the limiting component 13 is fixed on the steel structure 1, the surface of the steel structure 1 will not be scratched.

[0028] like Figure 1 、 Figure 6-Figure 8 As shown, each set of bellows 33 and telescopic rods 34 are arranged at equal angles in the annular direction on the inner wall of the metal shell 31. A set of gas spring telescopic rods 35 are respectively provided on both sides of each symmetrical set of bellows 33 and telescopic rods 34. The gas spring telescopic rods 35 are connected to the air storage box 32 and a steel ball 36 is installed at one end of the telescopic part. The other end of the telescopic part of the gas spring telescopic rod 35 on the same side movably penetrates the air storage box 32 and is commonly connected to a metal plate 37.

[0029] The above solution is adopted: when the bellows 33 and the telescopic rod 34 are matched and fixed on the steel structure 1, but the height still needs to be adjusted, the two metal plates 37 are pressed to move the telescopic end of the gas spring telescopic rod 35, and the steel balls 36 are rolled on the outside of the steel structure 1. At this time, part of the air inside the air storage box 32 is extracted into the steel balls 36, and the bellows 33 will no longer fit the outer periphery of the steel structure 1, so that the limit component 3 can slide on the outer periphery of the steel structure 1, thereby improving the flexibility of the device and improving the maneuverability of the device. Since the steel balls 36 and the gas spring telescopic rod 35 are located on both sides of the steel structure 1, when the limit component 3 as a whole moves by relying on several steel balls 36, no excessive deviation will occur, thereby causing the subsequent deviation of the inclination angle of the steel structure 2.

[0030] like Figures 1-11As shown, the locking assembly 4 includes a protective box 41 fixed to the side of the air storage box 32, the interior of the protective box 41 is elastically connected to the adjustment plate 43 through an elastic member 44, and two pneumatic telescopic rods 45 connected to the adjustment plate 43 are symmetrically installed inside the protective box 41, a tooth plate 42 is installed on the outside of the protective box 41, and a locking plate 46 is slidably installed on the outside of the adjustment plate 43, and an elastic member 47 is provided on the adjusting plate 43 to support the side of the locking plate 46, and a tooth plate 48 meshing with the tooth plate 42 is installed on the side of the locking plate 46.

[0031] The two pneumatic telescopic rods 45 are communicated with the interior of the air storage box 32 .

[0032] With the above solution, when the device is in a stationary state, the second elastic member 47 always supports the first locking plate 46, thereby causing the second tooth plate 48 to engage with the first tooth plate 42. At this time, the first locking plate 46 and the adjustment plate 43 are both in a stationary state, and the air inside the pneumatic telescopic rod 45 cannot flow into the interior of the air storage box 32. The limiting assembly 3 is in a fixed state, thereby improving the stability of the limiting assembly 3. Push the locking plate 1 46 to compress the elastic member 2 47 , so that the tooth plate 2 48 no longer contacts the tooth plate 1 42 . Then, the adjusting plate 43 can be pressed down, so that the air in the pneumatic telescopic rod 45 can enter the air storage box 32 , thereby driving the limit assembly 1 3 into the working state. When the weight of the steel structure 2 2 is too heavy, the adjusting plate 43 can be further lowered, so that the air inside the pneumatic telescopic rod 45 can continue to enter the air storage box 32 , further increasing the internal air pressure, making the fixed state of the limit assembly 1 3 more stable. Since air is compressible, when the device is subjected to external impact, the air inside the several bellows 33 will flow through the air storage box 32, thereby reducing the impact force and preventing the exterior of the steel structure 1 from being damaged by the device. The device as a whole can also reduce the probability of being damaged by the impact force, further protecting the steel structure 1 and avoiding unnecessary material loss during the construction process.

[0033] like Figure 1 and Figure 12 As shown, the limiting assembly 2 7 includes a supporting plate 71 which is hinged to the telescopic ends of the two spring telescopic plates 66. A number of bogies 73 are hinged to the two inner walls of the supporting plate 71 at equal distances. Each bogie 73 is elastically connected to the supporting plate 71 through an elastic member 4 75. The upper and lower ends of the bogie 73 are respectively mounted with a rubber wheel 74 rolled on the side of the steel structure 2.

[0034] The second limiting component 7 further includes two metal bars 72 symmetrically mounted on the supporting plate 71 , and the second steel structure 2 is placed on the two metal bars 72 .

[0035] The above solution is adopted: when the steel structure 2 is placed on the load-bearing plate 71, the rubber wheels 74 roll on both sides of the steel structure 2, and the two metal strips 72 are tightly attached to the bottom of the steel structure 2. At this time, the contact area between the steel structure 2 and the external structure is reduced, so that the steel structure 2 can slide more smoothly, and because the bogie 73 is hinged on the load-bearing plate 71, the elastic member 4 75 is also used to elastically connect with the load-bearing plate 71, which enables the rubber wheel 74 to always roll on the outer periphery of the steel structure 2, thereby adapting to steel structures 2 of different sizes.

[0036] The working principle and use process of the present invention: First, push the locking plate 1 46 to compress the elastic member 2 47, so that the tooth plate 2 48 no longer contacts the tooth plate 1 42. Then, press the adjustment plate 43 downward, so that the air of the pneumatic telescopic rod 45 enters the bellows 33 through the air storage box 32 and forces the telescopic rod 34 to extend. The end of the bellows 33 is tightly attached to the side of the steel structure 1, and the metal shell 31 and all the structures thereon are fixed to the steel structure 1. The presence of the telescopic rod 34 prevents the weight of the device from compressing the bellows 33 to bend. When the staff controls the steel structure 2 to rotate around the steel structure 1, the staff controls the telescopic plate 61 to slide on the arc frame 5 through the limit assembly 2 7, the spring telescopic plate 66, the extension plate 65, the slide plate 64 and the bracket 62; When the steel structure 2 is rotated to the appropriate position, the telescopic plate 61 can be manually pressed so that it can no longer slide on the arc frame 5. The steel structure 2 is swung, and the slide plate 64 can also be rotated on the bracket 62 to achieve another angle adjustment. By moving one end of the steel structure 2 up and down, the hinge angle between the extension plate 65 and the slide plate 64 is controlled by the limit assembly 2 7 and the spring expansion plate 66 to change, so that the angle between the steel structure 2 and the steel structure 1 can be further adjusted. When the angle adjustment between steel structure 1 and steel structure 2 is completed, manually press steel structure 2 against the side of steel structure 1 and slide limit assembly 2 7, causing the two spring expansion plates 66 to be compressed and folded. The fixed end of the spring expansion plate 66 pushes the locking plate 2 68 against the gear 2 69 through the guide plate 67. At this time, the extension plate 65 is fixed to the slide plate 64, and the angle of steel structure 2 can no longer be adjusted. The second locking plate 68 also pushes the driving plate 60 to retract into the second gear 69 via the inclined surface of the driving plate 60. The top of the guide rod 60 is displaced by the driving plate 60, and its bottom pushes the end of the third locking plate 603 to close to the first gear 63, so that the slide plate 64 can no longer rotate on the bracket 62, and the second steel structure 2 will also be in a stationary state. At this time, the position of the steel structure 2 can only be rotated around the steel structure 1 by the arc frame 5. The worker needs to press one end of the steel structure 2 to make the other end close to the outside of the steel structure 1.
