Description

Technical Field

[0001] This invention belongs to the technical field of high-altitude welding, specifically a high-altitude welding device for steel structure frames. Background Technology

[0002] With the rapid development of prefabricated buildings and steel structure engineering, high-altitude welding operations for steel structure frames of large-span stadiums, super high-rise office buildings, and industrial plants have become a key process in building construction. In high-altitude working environments, welding quality and construction safety are directly related to the load-bearing capacity and service life of the overall structure.

[0003] Currently, high-altitude welding operations generally suffer from the following technical defects in practical applications: Significant wind disturbances in the high-altitude environment easily disperse the welding shielding gas, disrupting the stability of the molten pool and leading to defects such as porosity, slag inclusions, and poor weld formation, severely impacting welding quality and structural safety. Furthermore, the welding process generates a large amount of high-temperature sparks and welding slag, which are prone to splashing and falling in the high-altitude environment, posing a significant safety hazard not only to burn equipment and personnel but also to ignite flammable materials below, potentially causing a fire. Summary of the Invention

[0004] This invention provides a high-altitude welding device for steel structure frames, which can solve the following problems in the prior art: (1) The wind disturbance in the high-altitude environment is obvious, which can easily blow away the welding shielding gas, destroy the stability of the molten pool, and cause defects such as porosity, slag inclusion, and poor forming of the weld, which seriously affect the welding quality and structural safety.

[0005] (2) A large number of high-temperature sparks and welding slag are generated during the welding process. They are prone to splashing and falling everywhere in the high-altitude environment, which can not only burn equipment and personnel, but also pose a major safety hazard of igniting combustibles below and causing a fire.

[0006] A high-altitude welding device for steel frame includes a lift, a fixed base fixedly connected to the top of the lift, support seats fixedly installed at the front and rear of the fixed base, a guide rail fixedly installed at the bottom of the support seat, a slide seat slidably installed on the guide rail, a collection box fixedly installed on the slide seat, and a connecting seat fixedly installed on another slide seat. A protective cover is fixedly connected to the top of the collection box. An adjustment mechanism and a welding machine body are fixedly installed on the top of the fixed base. The welding machine body is located on one side of the adjustment mechanism, and a welding torch is fixedly installed on the adjustment mechanism. The welding end of the welding torch is located directly behind the protective cover, and a guide sleeve is fixedly installed on the outside of the welding torch.

[0007] As a further technical solution of the present invention, the adjustment mechanism includes a transverse rail fixedly installed with a fixed base, a longitudinal rail slidably installed on the top of the transverse rail, and a limiting seat for fixing the welding gun slidably installed on the longitudinal rail, with the welding gun fixed in the limiting seat.

[0008] As a further technical solution of the present invention, two guide rods are slidably installed through the slide block, and the two ends of the guide rods are fixedly connected to the inner walls of both sides of the support base.

[0009] As a further technical solution of the present invention, the protective cover and the connecting seat are respectively fixedly installed at both ends of the longitudinal transfer rail. The protective cover includes a cover body, a collection cover is fixedly installed at the front of the cover body, and a positioning ring is fixedly installed at the front of the collection cover. A number of transverse rolling balls are embedded in the front of the positioning ring. A positioning sleeve that cooperates with the welding gun is fixedly installed at the rear of the cover body, and a limit ring is embedded in the rear wall of the positioning sleeve. A number of guide rolling balls are embedded in the inner wall of the limit ring.

[0010] As a further technical solution of the present invention, the guide sleeve includes an outer sleeve, on which a plurality of arc-shaped grooves are formed, and a sleeve groove is formed inside the outer sleeve.

[0011] As a further technical solution of the present invention, the outer sleeve is sleeved with the welding gun through a sleeve groove, and when the welding gun moves longitudinally, the guide ball rolls in the arc groove.

[0012] As a further technical solution of the present invention, a pull-out drawer is slidably installed inside the collection box, and fixing components for limiting the pull-out drawer are fixedly installed on both sides of the collection box.

[0013] As a further technical solution of the present invention, the rear vertical height of the collection box is lower than the front vertical height, and a handle is fixedly installed in the middle of the front of the pull-out drawer.

[0014] As a further technical solution of the present invention, the fixing component includes a fixing sleeve fixed to the side wall of the collection box, a spring installed inside the fixing sleeve, and a movable rod connected to the spring movably installed inside the fixing sleeve. A plane bearing is fixedly installed at the end of the movable rod away from the spring, a shaft is fixedly connected in the shaft hole of the plane bearing, a stop rod is fixedly connected at the end of the shaft away from the plane bearing, and a pad is fixedly connected on the side of the stop rod facing the drawer.

[0015] As a further technical solution of the present invention, one end of the spring is fixedly connected to one end of the interior of the fixed sleeve, and the other end of the spring is fixedly connected to one end of the movable rod.

[0016] The beneficial effects of this invention are as follows: By setting up a protective cover that moves synchronously with the longitudinal rail, this invention can always be precisely aligned with the welding torch, forming a stable protective barrier during the welding process. Combined with the pull-out drawer inside the collection box, it can collect and store the high-temperature sparks and welding slag generated during welding in real time and efficiently. At the same time, the collection cover provides omnidirectional shielding for the working area of ​​the welding torch, effectively isolating the interference of high-altitude winds on the welding process, and significantly improving welding quality and operational stability.

[0017] By setting a guide sleeve and opening an arc-shaped groove on the surface of the outer sleeve, which precisely matches the limiting ring on the positioning sleeve, it can always maintain a tight fit with the movement of the welding torch without affecting the smooth movement of the welding torch. This ensures that the welding torch accurately enters the collection hood, and structurally eliminates the risk of sparks and welding slag leaking from the limiting ring, further improving the reliability of the protection.

[0018] By setting up a fixed component, the pad is tightly fitted to the outside of the pull-out drawer, ensuring that the drawer remains stable during collection and preventing welding slag from spilling due to equipment vibration or movement. At the same time, the pad can be quickly separated from the drawer by rotating the shaft, making it easy to safely and conveniently remove the collected sparks and welding slag after welding, thus improving the ease of operation and maintenance efficiency of the device.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-8 As shown, a high-altitude welding device for a steel structure frame includes a lift 1. A fixed base 2 is fixedly connected to the top of the lift 1. Support seats 3 are fixedly installed at the front and rear of the fixed base 2. A guide rail 4 is fixedly installed at the bottom inner part of the support seat 3. A slide seat 5 is slidably installed on the guide rail 4. A collection box 7 is fixedly installed on the slide seat 5. A connecting seat 6 is fixedly installed on another slide seat 5. A protective cover 8 is fixedly connected to the top of the collection box 7. An adjustment mechanism and a welding machine body 14 are fixedly installed on the top of the fixed base 2. The welding machine body 14 is located on one side of the adjustment mechanism. A welding torch 12 is fixedly installed on the adjustment mechanism. The welding end of the welding torch 12 is located directly behind the protective cover 8. A guide sleeve 13 is fixedly installed on the outside of the welding torch 12.

[0024] The adjustment mechanism includes a transverse rail 9 fixedly installed with the fixed base 2, a longitudinal rail 10 slidably installed on the top of the transverse rail 9, and a limiting seat 11 for fixing the welding torch 12 slidably installed on the longitudinal rail 10, with the welding torch 12 fixed inside the limiting seat 11.

[0025] Specifically, the horizontal rail 9 drives the vertical rail 10 to move laterally, and the vertical rail 10 drives the welding torch 12 to move longitudinally, thereby adjusting the horizontal and forward / backward positions of the welding torch 12. The horizontal rail 9 and the vertical rail 10 are like the X-axis and Y-axis in the existing three-axis drive. The specific driving method is existing technology and will not be described in detail.

[0026] Two guide rods are slidably installed through the slide block 5, and the two ends of the guide rods are fixedly connected to the inner walls of both sides of the support block 3.

[0027] Specifically, by setting a guide rod, the protective cover 8 moves as the longitudinal rail 10 is driven, which in turn drives the slide 5 to move on the guide rail 4. The slide 5 slides on the surface of the guide rod, thus ensuring stability during movement.

[0028] The protective cover 8 and the connecting seat 6 are respectively fixedly installed at both ends of the longitudinal transfer rail 10. When the longitudinal transfer rail 10 moves, it can drive the protective cover 8 and the connecting seat 6 to move synchronously, so that the welding torch 12 can always be aligned with the protective cover 8. When the protective cover 8 and the connecting seat 6 move, the slide 5 can also slide synchronously to ensure the stability of both ends of the longitudinal transfer rail 10. The protective cover 8 includes a cover body 81. A collection cover 83 is fixedly installed at the front of the cover body 81, and a positioning ring 84 is fixedly installed at the front of the collection cover 83. Several transverse ball bearings 85 are embedded at the front of the positioning ring 84. A positioning sleeve 82 that cooperates with the welding torch 12 is fixedly installed at the rear of the cover body 81, and a limit ring 86 is embedded in the rear wall of the positioning sleeve 82. Several guide ball bearings 87 are embedded in the inner wall of the limit ring 86.

[0029] Specifically, after the welding torch 12 moves, it enters the positioning sleeve 82 and then enters the collection cover 83, aligning with the welding position. When the welding torch 12 is welding, the collection cover 83 is used to shield the sparks and slag generated during welding, thereby collecting them into the cover 81 and then dropping them into the drawer 16 inside the collection box 7.

[0030] The guide sleeve 13 includes an outer sleeve 131, which has several arc-shaped grooves 133 and a connecting groove 132 inside. The outer sleeve 131 is connected to the welding torch 12 through the connecting groove 132. When the welding torch 12 moves longitudinally, the guide ball 87 rolls in the arc-shaped groove 133.

[0031] Specifically, when the welding torch 12 moves, the guide balls 87 roll in the arc groove 133, and the rest of the outer sleeve 131 fills the gap between the guide balls 87 in the limiting ring 86, thereby ensuring the sealing of the contact area between the welding torch 12 and the limiting ring 86.

[0032] A pull-out drawer 16 is slidably installed inside the collection box 7, and fixing components 15 for limiting the pull-out drawer 16 are fixedly installed on both sides of the collection box 7. The vertical height of the rear of the collection box 7 is lower than that of the front, and a handle is fixedly installed in the middle of the front of the pull-out drawer 16.

[0033] Specifically, the rear of the collection box 7 is lower than the front to avoid contact with the surface of the fixed base 2 and cause wear.

[0034] The fixing assembly 15 includes a fixing sleeve 151 fixed to the side wall of the collection box 7. A spring 152 is installed inside the fixing sleeve 151, and a movable rod 153 connected to the spring 152 is also movably installed inside the fixing sleeve 151. A plane bearing 154 is fixedly installed at the end of the movable rod 153 away from the spring 152. A shaft 155 is fixedly connected in the shaft hole of the plane bearing 154. A stop rod 156 is fixedly connected at the end of the shaft 155 away from the plane bearing 154, and a pad 157 is fixedly connected on the side of the stop rod 156 facing the drawer 16. One end of the spring 152 is fixedly connected to one end inside the fixing sleeve 151, and the other end of the spring 152 is fixedly connected to one end of the movable rod 153.

[0035] Specifically, the stop lever 156 can be pulled to extend the spring 152, causing the pad 157 to detach from the surface of the drawer 16. The stop lever 156 can be rotated via the shaft 155 to avoid obstructing the surface of the drawer 16, thus facilitating the removal of the drawer 16. During collection, the limiting function of the spring 152 ensures that the pad 157 adheres to the surface of the drawer 16, effectively fixing the position of the drawer 16 and preventing it from becoming loose.

[0036] The present invention discloses a high-altitude welding device for steel structure frames. In use, the lifting platform 1 is used to raise and lower the device, and the height of the fixed base 2 is adjusted to change the operating height of the welding torch 12, so that the welding torch 12 can perform welding operations on steel structure frames of different heights.

[0037] The horizontal rail 9 drives the vertical rail 10 to move laterally, and the vertical rail 10 drives the welding torch 12 to move longitudinally, thereby adjusting the horizontal and front-back positions of the welding torch 12. The welding torch 12 is used in conjunction with the welding machine body 14 to weld the connection points of the steel structure frame.

[0038] During welding, the longitudinal guide rail 10 drives the welding torch 12 to move toward the protective cover 8. First, the welding torch 12 enters the limiting ring 86 on the positioning sleeve 82, and the guide sleeve 13 on the surface of the welding torch 12 enters the positioning sleeve 82. Then, the guide ball 87 rolls in the arc groove 133, the outer sleeve 131 enters the cover 81, and then enters the collection cover 83. The collection cover 83 is moved by the elevator 1 to pre-align and fit with the welding area.

[0039] After the longitudinal transfer rail 10 is aligned with the welding area, the welding operation is carried out under the drive of the welding machine body 14. The sparks and welding slag generated during the welding process are guided to the inside of the cover 81 through the collection cover 83, and then enter the inside of the collection box 7, and are finally collected by the pull-out drawer 16.

[0040] The pull-out drawer 16 is fixed by the fixing component 15. The stop bar 156 can be rotated through the shaft 155 to not obstruct the surface of the pull-out drawer 16, thus making it easy to take out the pull-out drawer 16. During collection, the limit of the spring 152 makes the pad 157 fit against the surface of the pull-out drawer 16 to prevent it from becoming loose.

[0041] As the longitudinal rail 10 is adjusted horizontally via the transverse rail 9, the protective cover 8 moves along with the longitudinal rail 10, ensuring that the protective cover 8 is always positioned directly in front of the welding torch 12. When the protective cover 8 moves, the transverse ball 85 on the positioning ring 84 rolls, facilitating its movement and making it easier for the welding torch 12 to change positions for welding operations.

[0042] In addition, patent number CN210915140U discloses "a pneumatic lift", which has already disclosed the specific lifting method. The lift 1 in this application belongs to the prior art and will not be described in detail here.

[0043] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
