Description

Technical Field

[0001] This invention relates to the field of beam welding technology, and in particular to a prefabricated house frame welding equipment and its usage method. Background Technology

[0002] Prefabricated house frames are a type of building structure that uses steel as the main material and is constructed by assembling multiple steel bars in a grid pattern. They are characterized by high strength, light weight, and high rigidity. Welding equipment is required to connect the nodes between the prefabricated house frames.

[0003] Currently, welding of prefabricated house frames is still mainly done manually. When welding the area beneath the steel, welders must adopt an upward-looking posture with their heads tilted back and bodies leaning backward. In this posture, the human body is in an unstable state of balance, and once the balance is lost, there is a high risk of falling from the scaffolding. At the same time, falling weld slag directly threatens the operator's body, posing a significant safety hazard. In addition, viewing the weld at an angle obstructs the line of sight and results in a very poor viewing angle, seriously affecting the welding accuracy.

[0004] Among existing welding methods for areas out of sight, "mirror welding" is mainly used in completely enclosed spaces such as small-diameter pipes and the inner walls of containers, where observation is achieved by placing a mirror below the workpiece for reflection. However, when used directly for welding roof beams, its applicability is extremely limited because the width of the roof beam steel is much larger than the diameter of the pipe, exposing two major problems: 1) Limited viewing angle: When standing on one side of the roof beam and observing the weld seam on the other side directly below through a single mirror, the line of sight forms a very small grazing angle with the mirror surface, resulting in weak reflected light and a dim or even completely invisible image; 2) Insufficient field of view coverage: Even if a part can be observed, the field of view of a single mirror is extremely limited; to cover the weld seam across the entire width of the roof beam, the mirror and the user's position must be frequently and significantly moved, making the operation cumbersome and preventing continuous welding.

[0005] In summary, the existing manual overhead welding method poses significant safety risks and is difficult to control in terms of quality; while traditional mirror welding technology cannot effectively meet the welding needs of large and wide structures such as roof beams. Therefore, this paper proposes an integrated house frame welding equipment and its usage method to address the above problems. Summary of the Invention

When welding the bottom of the house beam, the observation mechanism allows for clear observation of the weld seam at the bottom of the house beam, eliminating the need for workers to observe the weld seam at an angle. This facilitates workers holding the welding torch for welding. Simultaneously, as the worker moves the welding torch, the observation mechanism can adjust the position of the weld seam observation in real time, ensuring that workers can clearly see the weld seams at different locations on the bottom of the house beam, regardless of the width of the house beam. This ensures that there are no problems with limited viewing angle or insufficient field of vision during welding.

[0036] Example like Figures 1-13As shown, a prefabricated house frame welding device and its usage method include a crossbeam 4 and a guide rail 5. Both ends of the guide rail 5 are fixedly connected to the crossbeam 4. A slider 6 is slidably connected to the outer side of the guide rail 5. There are two guide rails 5, symmetrically distributed inside the slider 6. The two guide rails 5 provide stable guidance and limiting for the movement of the slider 6. One end of the slider 6 is fixedly connected to a support frame 7. A limiting shell 8 is fixedly connected to the inner side of the support frame 7. A rotating ball 9 is rotatably connected to the inner side of the limiting shell 8. A welding gun head 10 is movably disposed inside the rotating ball 9. The rotating ball 9 can rotate omnidirectionally inside the limiting shell 8, while the welding gun head 10 can move flexibly inside the rotating ball 9. With the cooperation of the two, the staff can precisely adjust the welding gun head 10 to the required welding position; one end of the slider 6 is fixedly connected to the observation mechanism 1. During the welding process, when the welding gun head 10 moves along the weld seam, the main reflector 120 inside the observation mechanism 1 moves synchronously through the linkage of the rotating ball 9, the limiting shell 8 and the support frame 7; this structure ensures that when welding at different positions at the bottom of the beam, the operator can always obtain a clear and continuous weld seam view, which is not affected by the width of the beam, and fundamentally solves the problems of limited viewing angle and insufficient field of view coverage; one end of the observation mechanism 1 is equipped with a positioning and cleaning mechanism 2, and one end of one of the crossbeams 4 is fixedly connected to a fixing mechanism 3.

[0037] As a further improvement to the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the observation mechanism 1 includes a first support rod 101 and a second support rod 102. The first support rod 101 is fixedly connected to the crossbeam 4, and the second support rod 102 is fixedly connected to the slider 6. One end of the second support rod 102 is rotatably connected to the positioning and cleaning mechanism 2 via a rotating shaft. A main reflector 120 is fixedly connected to the inner side of the positioning and cleaning mechanism 2. A second relay reflector 122 and a first relay reflector 121 are rotatably connected to the upper and lower sides of one end of the first support rod 101 via rotating shafts, respectively. An adjusting plate 125 is slidably connected to one end of the fixing mechanism 3. A support frame 124 is fixedly connected to the top of the adjusting plate 125. The inner side of the support frame 124 is connected to the slider 6 via a rotating shaft. The observation mirror 123 is rotatably connected. The horizontal position of the observation mirror 123 can be adjusted by moving the adjustment plate 125, so that the staff can place it at the most suitable observation angle. The main reflector 120 is deployed directly below the weld of the roof beam. The weld image reflected by it is transmitted in sequence through the first relay reflector 121 and the second relay reflector 122, and finally clearly presented in the observation mirror 123. Based on this optical transmission path, when the staff is standing on the scaffolding, they do not need to look up and look at the weld. They can simply observe the weld status in real time through the observation mirror 123, and at the same time reach their hands under the roof beam to hold the welding gun head 10 to complete the welding operation, realizing the coordinated adaptation of observation and welding actions.

[0038] The positioning and cleaning mechanism 2, the first relay reflector 121, and the second relay reflector 122 are all equipped with synchronous adjustment components at one end. The support frame 124, the first support rod 101, and the second support rod 102 are all threaded with locking screws 126 at one end, and the locking screws 126 are all abutted against the rotating shaft. When the main reflector 120, the first relay reflector 121, the second relay reflector 122, and the observation mirror 123 are adjusted to a suitable operating angle, the locking screws 126 abut against the corresponding rotating shafts. Through the friction between the locking screws 126 and the rotating shafts, the main reflector 120, the first relay reflector 121, the second relay reflector 122, and the observation mirror 123 are limited and fixed, ensuring the stability of the main reflector 120, the first relay reflector 121, the second relay reflector 122, and the observation mirror 123 during operation.

[0039] As a further improvement to the present invention, such as Figure 3 , Figure 9 and Figure 10 As shown, the synchronous adjustment assembly includes a positioning and cleaning mechanism 2, a first relay reflector 121, and a second relay reflector 122, both fixedly connected to a first gear 103 via a rotating shaft. A rack 104 meshes with the bottom end of the first gear 103, and a base plate 105 is slidably connected to the bottom end of the rack 104. A limit frame 106 is fixedly connected to the top end of the base plate 105, and the limit frame 106 is slidably connected to the rack 104. The limit frame 106 and the base plate 105 guide and limit the rack 104, ensuring that the rack 104 can rotate normally with the first gear 103. One end of a first support rod 101 is fixedly connected to... A side plate 118 is attached, with a first screw 119 rotatably connected to one end of the side plate 118. A push rod 127 is threaded onto the outer side of the first screw 119. The push rod 127 is fixedly connected to two racks 104 arranged vertically. An angle scale (accuracy 1°) can be set on the side of the first support rod 101, marked with an adjustment range of "0°-90°", so that the operator can intuitively confirm whether the current angle of the main reflector 120, the first relay reflector 121, and the second relay reflector 122 meets the 45° (error ≤ 1°) coordination requirement. A transition component is provided between the two horizontally arranged racks 104. When adjusting the operating angles of the main reflector 120, the first relay reflector 121, and the second relay reflector 122, firstly, separate the locking screw 126 from the rotating shaft connecting the positioning and cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122, allowing the rotating shaft to rotate freely. Then, the operator rotates the first screw 119, causing it to spiral inside the push rod 127. This causes the push rod 127 to slide along the limiting frame 106 and the base plate 105, carrying the corresponding rack 104. Simultaneously, the rack 104 at the bottom will move along with another rack 104 via the transition component, causing the three racks 104 in different positions to rotate synchronously. Then, the different... The rack 104 at the position will synchronously rotate the corresponding first gear 103. Then, the first gear 103 will synchronously rotate the positioning and cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122, thereby achieving synchronous adjustment of the tilt angle of the main reflector 120, the first relay reflector 121, and the second relay reflector 122, so that the angle between the main reflector 120, the first relay reflector 121, and the second relay reflector 122 and the horizontal direction is 45° (error ≤ 1°). The traditional method requires adjusting the angle of each mirror separately, which is time-consuming and prone to errors; while the synchronous adjustment component can complete the optical path calibration with only one operation, shortening the adjustment time and improving the operation efficiency. Furthermore, the synchronized adjustment mechanism ensures that the angles of the main reflector 120, the first relay reflector 121, and the second relay reflector 122 remain coordinated. Even if the equipment is subjected to welding vibration or external interference, the optical path will not deviate, thus solving the problem of dim or distorted vision caused by angle deviation. Meanwhile, when the height, width, or welding position of the beam changes, the optical path can be quickly adjusted through the synchronous adjustment component, without the need to recalculate the angle of each mirror, greatly improving the scene adaptability of the equipment.

[0040] As a further improvement to the present invention, such as Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the transition component includes two horizontally arranged racks 104 with their adjacent ends fixedly connected by connecting seats 107. One end of one connecting seat 107 is rotatably connected to a connecting frame 109, and one end of the other connecting seat 107 is rotatably connected to a connecting rod 108. The other end of the connecting rod 108 is fixedly connected to a connecting shaft 117, and the connecting rod 108 is rotatably connected to the connecting frame 109 through the connecting shaft 117. The connecting frame 109 adopts a "U"-shaped structure design. When the connecting frame 109 and the connecting rod 108 rotate relatively close to each other, the connecting rod 108 can be embedded in the gap inside the connecting frame 109, thereby reducing the spatial interference between the two and significantly expanding the movement range of the main reflector 120 and the welding gun head 10, so as to meet the welding requirements of different positions of the beam weld. Meanwhile, the connecting seat 107, the connecting frame 109, and the connecting shaft 117 constitute a force transmission assembly: the rack 104 located at the bottom and installed on the side of the first support rod 101 can transmit its power through the connecting seat 107, the connecting frame 109, and the connecting shaft 117 in sequence, thereby driving the rack 104 on the side of the second support rod 102 to rotate synchronously, ensuring the consistency of transmission.

[0041] As a further improvement to the present invention, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a fixed cylinder 110 is fixedly connected to one end of the connecting frame 109, a guide plate 111 is fixedly connected to the inner side of the fixed cylinder 110, a chuck 113 is fixedly connected to one end of the connecting shaft 117, a slot 114 is provided around the chuck 113, a guide rod 115 is slidably connected to the inner side of the guide plate 111, a clamp head 112 is fixedly connected to one end of the guide rod 115, and the clamp head 112 engages with the chuck 113 through the slot 114, a spring 116 is provided on the outer side of the guide rod 115, and the two ends of the spring 116 are fixedly connected to the guide plate 111 and the clamp head 112 respectively. When it is necessary to adjust the tilt angle of the positioning cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122, firstly, separate the locking screw 126 from the rotating shaft connected to the positioning cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122, so that the rotating shaft can rotate freely; at the same time, the spring 116 limits and fixes the chuck 113 through the chuck head 112. Under the action of the chuck head 112, the chuck 113, the guide rod 115, the guide plate 111, the connecting shaft 117, and the fixing cylinder 110, the connecting frame 109 and the connecting rod 108 form a whole. When the rotating shaft connected to the positioning cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122 can rotate freely, the adjacent racks 104 at the bottom can transmit power through the connecting seat 107, the connecting frame 109, and the connecting shaft 117. After the tilt angles of the positioning cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122 are adjusted to appropriate positions, the locking screw 126 abuts against the rotating shaft, preventing the shaft from rotating arbitrarily. This also prevents relative movement between the rack 104 and the first gear 103, thus achieving the limiting and fixing of the positioning cleaning mechanism 2, the main reflector 120, the first relay reflector 121, and the second relay reflector 122. When the worker needs to move the welding position while welding the weld seam using the welding torch head 10, the worker moves the welding torch head 10 through the rotating ball 9, the limiting shell 8, the support frame 7, the slider 6, the second support rod 102, and the positioning cleaning machine. The mechanism 2 moves synchronously with the main reflector 120. At the same time, the slider 6 also applies a thrust to the connecting frame 109 through the second support rod 102, the corresponding first gear 103, and the rack 104 via the connecting seat 107. This causes the connecting frame 109 to overcome the resistance between the chuck 112 and the slot 114 through the fixed cylinder 110, guide plate 111, and guide rod 115, causing the chuck 112 to rotate along the chuck 113. This results in relative rotation between the connecting frame 109 and the connecting rod 108, while also ensuring that the operator can smoothly move the welding torch head 10 synchronously with the main reflector 120 through the rotating ball 9, the limiting shell 8, the support frame 7, the slider 6, the second support rod 102, and the positioning and cleaning mechanism 2.

[0042] As a further improvement to the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 11 , Figure 12 and Figure 13As shown, the positioning and cleaning mechanism 2 includes an outer ring 201 rotatably connected to the second support rod 102 via a rotating shaft. The outer ring 201 is fixedly connected to the main reflector 120 and also fixedly connected to the corresponding first gear 103 via a rotating shaft. The outer ring 201 is also rotatably connected to the second support rod 102 via a rotating shaft. A gear ring 202 is rotatably connected between the outer ring 201 and the main reflector 120. A fixing plate 209 is fixedly connected to one end of the gear ring 202, and a positioning rod 210 is rotatably connected to one end of the fixing plate 209. A cleaning pad 211 is fixedly connected to one end of the positioning rod 210. The gear ring 202 can carry the positioning rod 210 and the cleaning pad 211 through the fixing plate 209. The cleaning pad 211 rotates; the cleaning pad 211 is made of rubber. Through the cooperation of the positioning rod 210 and the cleaning pad 211, the welding slag attached to the surface of the main reflector 120 can be cleaned to prevent the welding slag from affecting the normal operation of the main reflector 120. A torsion spring 212 is provided between the positioning rod 210 and the fixing plate 209. Under the torsion of the torsion spring 212, when not in use, the positioning rod 210 and the cleaning pad 211 are in a vertical state relative to the outer ring 201 and rotate to the side of the outer ring 201 to ensure that the positioning rod 210 and the cleaning pad 211 do not block the main reflector 120, thereby ensuring that the operator's field of vision is not affected by other parts. As a further improvement to the present invention, such as Figure 11 , Figure 12 and Figure 13 As shown, a connecting shell 206 is fixedly connected to one end of the outer ring 201, and a motor 207 is fixedly connected to the inner side of the connecting shell 206. A battery box for storing batteries can be installed at the bottom of the slider 6 to provide power to the motor 207. A controller for controlling the start and stop of the motor 207 can also be installed on the side of the second support rod 102 or other components, allowing workers to operate the controller with their other hand during welding. A second gear 208 is fixedly connected to the end of the main shaft of the motor 207. 8 meshes with the toothed ring 202. The outer ring 201 is fixedly connected to a fixing block 203. One end of the fixing block 203 is fixedly connected to a limiting ring 204. One end of the limiting ring 204 is fixedly connected to a guide block 205. The guide block 205 is set at an angle upward and has a curved surface that guides the positioning rod 210. At the same time, the ends of the guide block 205 and the limiting ring 204 have cavities to accommodate the positioning rod 210 and the cleaning pad 211, so that the positioning rod 210 and the cleaning pad 211 can rotate into this cavity when not in use. Before welding, if the weld seam under the beam needs to be in the center of the main reflector 120, the positioning rod 210 needs to be in a state parallel to the main reflector 120. At the same time, a conspicuous mark can be set on the surface of the outer ring 201 in a direction parallel to the weld seam. When the positioning rod 210 is aligned with the mark, the position pointed to by the positioning rod 210 is the center of the main reflector 120. When the weld seam is aligned with the positioning rod 210, it can also be ensured that the weld seam is in the center of the main reflector 120. When the positioning rod 210 needs to rotate to the marked position, the motor 207 drives the gear ring 202 to rotate counterclockwise via the second gear 208 (viewed from top to bottom). Then, the gear ring 202 drives the positioning rod 210 and the cleaning pad 211 to rotate counterclockwise synchronously via the fixing plate 209. When the positioning rod 210 contacts the guide block 205, under the guidance and limitation of the guide block 205, the positioning rod 210 overcomes the torque of the torsion spring 212 and gradually moves the cleaning pad 211 towards the main reflector 120. When the positioning rod 210 and the cleaning pad 211 rotate to the lower part of the limiting ring 204, the positioning rod 210, along with the cleaning pad 211, is parallel to the main reflector 120 under the limiting action of the limiting ring 204, and the cleaning pad 211 also contacts the surface of the main reflector 120. When the positioning rod 210 rotates to the marked position, the motor 207 stops working. At this time, the position of the main reflector 120 can be adjusted so that the weld seam is aligned with the positioning rod 210. When it is necessary to clean the welding slag adhering to the surface of the main reflector 120 by cleaning the cleaning pad 211, the motor 207 can be made to rotate continuously with the positioning rod 210 and the cleaning pad 211 through the second gear 208, the gear ring 202, the fixing plate 209.

[0043] As a further improvement to the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the fixing mechanism 3 includes a vertical plate 301 fixedly connected to one of the crossbeams 4. A clamping plate 302 is fixedly connected to the top of the vertical plate 301, and the clamping plate 302 is slidably connected to the adjusting plate 125. A top plate 303 is fixedly connected to one end of the clamping plate 302. A second screw 304 is threadedly connected to the inner side of one end of the top plate 303. A clamping disc 305 is fixedly connected to one end of the second screw 304. When it is necessary to fix the device to the roof beam, the top plate 303 is first placed on the roof beam. When the weld is adjusted to be in the center position of the main reflector 120, the clamping disc 305, along with the second screw 304, rotates spirally inside the top plate 303. The device is clamped and fixed to the roof beam through the mutual cooperation of the clamping disc 305 and the clamping plate 302.

[0044] As a further improvement to the present invention, such as Figure 4As shown, the bottom of the clamping plate 302 is provided with a placement groove 306; the placement groove 306 is U-shaped. When welding the weld seam on the upper part of the beam, the placement groove 306 can accommodate the weld seam, ensuring that the protruding part of the weld seam will not affect the clamping plate 302 being placed horizontally on the top surface of the beam.

[0045] As a further improvement to the present invention, such as Figures 1-13 As shown, the usage method is as follows: S1: The device is clamped and fixed to the roof beam by the fixing mechanism 3; S2: The location of the weld between adjacent beams is observed through the observation mechanism 1, and the position of the weld is made to be in the center of the main reflector 120 through the positioning and cleaning mechanism 2. S3: Pass the welding torch head 10 through the rotating ball 9, and then weld the weld between adjacent beams through the welding torch head 10.
