Description

Technical Field

[0001] This invention belongs to the field of hanger welding technology, specifically a welding device for steel structure hangers. Background Technology

[0002] Steel structure hangers typically consist of a bottom support bracket and two side fixed brackets. To ensure the balance and stability of the support bracket, the included angles between the bottom ends of the two fixed brackets and the support bracket must be equal. Currently, when manufacturing steel structure hangers, companies weld one side first and then the other side when welding the support bracket and the two side fixed brackets. Due to the sequential welding order, and the inability to guarantee that the included angle readings are consistent between the two welding operations, slight differences in the included angle readings can easily occur, causing the hanger to tilt during use. Therefore, improvements and optimizations are needed. Summary of the Invention

[0003] The purpose of this invention is to provide a welding device for steel structure hangers to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a welding device for a steel structure hanger, comprising a base plate, a housing mounted on the top of the base plate, a fixed oil pipe mounted inside the housing, a fixed frame and a fixed block mounted on the top of the housing, a movable plate movably mounted inside the fixed oil pipe, a first vertical rod fixedly mounted on the top of the movable plate, the first vertical rod extending upward through the housing and hinged to a movable frame, a first spring elastically connected to the outer surface of the first vertical rod between the top of the inner cavity of the housing and the movable plate, a first vertical block located inside the housing being fixedly connected to the top of the fixed oil pipe, a horizontal plate movably mounted on the top of the first vertical block, a motor fixedly mounted on the top of the horizontal plate, the output end of the motor extending downward through the horizontal plate and into the interior of the first vertical block and fixedly mounted with a rotating plate, a first cavity being formed inside the first vertical block, a second vertical rod fixedly mounted on the bottom end of the rotating plate, and a first movable plate located inside the first cavity being fixedly mounted on the bottom end of the second vertical rod.

[0005] Preferably, a second groove is provided on the top of the housing, a cleaning block is movably installed on the top of the housing, a second vertical block is installed at the bottom of the cleaning block, the bottom of the second vertical block extends downward into the interior of the housing and a first moving block is fixedly installed thereon, and the first moving block is hinged to the horizontal plate by a connecting rod.

[0006] Preferably, the top of the movable frame is provided with an installation groove, the interior of the movable frame is provided with a second cavity, a second moving block is movably installed inside the second cavity, a moving rod is fixedly installed on the top of the second moving block, the top of the moving rod passes through the movable frame upward and is fixedly installed with a second movable plate, and a second spring located on the top of the second moving block is elastically connected inside the second cavity.

[0007] Preferably, the fixing blocks are located on both sides of the fixing frame, and the fixing blocks are in the shape of bosses, with the bottom diameter of the fixing blocks being larger than the top diameter.

[0008] Preferably, a first vertical plate located on both sides of the first vertical block is fixedly installed at the bottom end of the horizontal plate, and a first groove is provided inside the first vertical block, with a limit block slidably installed inside the first groove.

[0009] Preferably, a second vertical plate is fixedly installed on the top of the housing, and there are two second vertical plates. A welding mechanism is fixedly installed on the front of each of the two second vertical plates.

[0010] Preferably, the bottom of the movable frame is fixedly installed with limiting rods located on the left and right sides of the first vertical rod, and the top of the limiting rods is perpendicular to the bottom of the movable frame.

[0011] Preferably, a clamping plate is movably installed inside the fixing frame, a rotating block is fixedly installed on the side of the clamping plate, and the other end of the rotating block passes through the fixing frame and is fixedly installed with a crossbar.

[0012] Preferably, the fixed oil pipe is U-shaped, and the hydraulic oil levels at both ends inside the fixed oil pipe are equal.

[0013] This device is small in size and portable. Its application is for steel structure hangers for door and window frames. During the welding of three steel structures, the principle of communicating vessels is used to ensure that two sections are at the same height. Compared to synchronous motors, this device, using the principle of communicating vessels in its modification, allows the motor to drive a rotating plate to rotate during the resetting of the cleaning block. This rotating plate then drives the first movable plate upwards, drawing oil from the fixed oil pipe into the first cavity. Simultaneously, the height of both ends of the fixed oil pipe moves downwards, causing the first vertical rod to descend along with the oil level, thus lowering the movable frame and saving storage space. Furthermore, by controlling the oil level inside the fixed oil pipe and utilizing the low compressibility of hydraulic oil, the installation height of the movable frame can be adjusted to accommodate different angle welding methods. However, two synchronous motors are more expensive, and the electrical maintenance costs are not low, and their stability is not as good as that of hydraulic oil itself.

[0014] Because the movable frame and the first vertical rod are connected by a hinge, as the first vertical rod moves up and down, the movable frame can be rotated to a suitable angle, allowing the hanger on the movable frame to be welded to the crane placed on the fixed frame at different angles. This is suitable for most hanger welding situations on the market.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention, by setting up a motor, a rotating plate, a second vertical rod, and a movable frame, uses the motor to drive the rotating plate downwards via the second vertical rod to move the first movable plate. By squeezing the hydraulic oil inside the fixed oil pipe, the first vertical rods on both sides move upwards synchronously. Compared with traditional devices, this device utilizes the principle of communicating vessels. After pressurizing the hydraulic oil inside the fixed oil pipe, both ends of the fixed oil pipe are subjected to the same pressure, thereby causing the two first vertical rods to move upwards synchronously. This, in turn, enables the two movable frames to rotate at the same angle, thus achieving synchronous welding at both ends and avoiding welding angle deviations.

[0017] 2. This invention, by setting up a motor, a horizontal plate, and cleaning blocks, uses the operation of the motor to cause the rotating plate to rotate in the opposite direction, thereby driving the first movable plate and the horizontal plate to move upward. Through the transmission action of the connecting rod, the two cleaning blocks are pushed to move in opposite directions. Compared with the traditional device, this device uses the reverse rotation of the rotating plate to reset the horizontal plate upward, thereby driving the cleaning blocks to perform cleaning operations, so that the movable frame returns to its original state. At the same time, the cleaning blocks clean the welding slag, preventing the accumulation of welding slag and affecting subsequent welding operations.

[0018] 3. By setting a second movable plate and a second spring, compared with the traditional device, the second movable plate applies a certain downward compressive force to the steel structure through the elastic force of the second spring, making the connection between the steel structures more tightly connected. This avoids unstable welding points or misalignment of contact points due to loose contact, thereby improving welding stability and efficiency. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] like Figures 1 to 8As shown, this embodiment of the invention provides a welding device for a steel structure hanger, including a base plate 1, a housing 2 mounted on the top of the base plate 1, a fixed oil pipe 3 installed inside the housing 2, a fixed frame 4 and a fixed block 5 mounted on the top of the housing 2, a movable plate 6 movably mounted inside the fixed oil pipe 3, a first vertical rod 7 fixedly mounted on the top of the movable plate 6, the first vertical rod 7 extending upward through the housing 2 and hinged to a movable frame 9, and a first spring 8 elastically connected to the outer surface of the first vertical rod 7, located between the top of the inner cavity of the housing 2 and the movable plate 6, for fixing... The top of the oil pipe 3 is fixedly connected to a first vertical block 10 located inside the housing 2. A horizontal plate 17 is movably installed on the top of the first vertical block 10. A motor 11 is fixedly installed on the top of the horizontal plate 17. The output end of the motor 11 passes through the horizontal plate 17 downward and extends into the interior of the first vertical block 10, where a rotating plate 13 is fixedly installed. A first cavity 14 is opened inside the first vertical block 10. A second vertical rod 15 is fixedly installed at the bottom of the rotating plate 13. A first movable plate 16 located inside the first cavity 14 is fixedly installed at the bottom of the second vertical rod 15.

[0030] In this process, the workers place the steel structure to be welded on the fixed frame 4 and the movable frame 9. The bottom end of the steel structure on the movable frame 9 contacts the two ends of the steel structure on the fixed frame 4. At this time, the movable frame 9 is in an inclined state. When the angle of the movable frame 9 needs to be adjusted, the motor 11 is started. Due to the operation of the motor 11, the vertical shaft 12 and the rotating plate 13 will rotate. Due to the threaded fit between the outer surface of the rotating plate 13 and the inner surface of the first vertical block 10, the rotating plate 13 drives the first movable plate 16 to move downward through the second vertical rod 15. The first movable plate 16 squeezes the hydraulic oil inside the fixed oil pipe 3, thereby pushing the movable plate 6 upward through the hydraulic oil. At this time, the first vertical rod 7 moves upward, and the first spring 8 is in a state of elastic compression. Due to the upward push of the first vertical rod 7, the movable frame 9 rotates and slides relative to the steel structure placed on the surface of the movable frame 9.

[0031] The operation of motor 11 causes rotating plate 13 to push the first movable plate 16 downward via second vertical rod 15. By squeezing the hydraulic oil inside fixed oil pipe 3, the first vertical rods 7 on both sides move upward synchronously. Compared with traditional devices, this device utilizes the principle of communicating vessels. After pressurizing the hydraulic oil inside fixed oil pipe 3, both ends of fixed oil pipe 3 are subjected to the same pressure, thereby causing the two first vertical rods 7 to move upward synchronously. This results in the two movable frames 9 rotating at the same angle, thus achieving synchronous welding at both ends and avoiding welding angle deviation.

[0032] like Figure 1 , Figure 2 and Figure 8As shown, a second groove 21 is provided on the top of the housing 2, a cleaning block 22 is movably installed on the top of the housing 2, a second vertical block 23 is installed at the bottom of the cleaning block 22, the bottom of the second vertical block 23 extends downward into the interior of the housing 2 and a first moving block 24 is fixedly installed thereon, and the first moving block 24 is hinged to the horizontal plate 17 through a connecting rod 25.

[0033] After welding, the motor 11 is restarted, which drives the rotating plate 13 to rotate in the opposite direction. The rotating plate 13 and the inner surface of the first vertical block 10 are threaded together, causing the rotating plate 13, the second vertical rod 15 and the first movable plate 16 to move upward. At this time, the vertical shaft 12 drives the horizontal plate 17 to move upward, the connecting rod 25 drives the first moving block 24 to move to both sides, and the second vertical block 23 drives the cleaning block 22 to move on the top of the shell 2. The cleaning block 22 cleans the welding slag on the top of the shell 2 below the two steel structure welding points.

[0034] The operation of motor 11 causes rotating plate 13 to rotate in the opposite direction, which in turn drives first movable plate 16 and horizontal plate 17 to move upward. Through the transmission action of connecting rod 25, two cleaning blocks 22 are pushed to move in opposite directions. Compared with traditional devices, this device uses the reverse rotation of rotating plate 13 to reset horizontal plate 17 upward, thereby driving cleaning blocks 22 to perform cleaning operations, so that movable frame 9 returns to its original state. At the same time, cleaning blocks 22 clean welding slag, preventing welding slag accumulation and affecting subsequent welding operations.

[0035] like Figure 4 and Figure 7 As shown, the top of the movable frame 9 is provided with an installation groove 26, the inside of the movable frame 9 is provided with a second cavity 27, the second moving block 28 is movably installed inside the second cavity 27, the top of the second moving block 28 is fixedly installed with a moving rod 29, the top of the moving rod 29 passes through the movable frame 9 upward and is fixedly installed with a second movable plate 30, and the inside of the second cavity 27 is elastically connected with a second spring 31 located at the top of the second moving block 28;

[0036] Specifically, pulling the second movable plate 30 causes the second movable plate 30 to drive the moving rod 29 and the second moving block 28 to move upward inside the movable frame 9. At this time, the second spring 31 is under pressure and is in a state of elastic compression. After the steel structure is placed inside the mounting groove 26, the second movable plate 30 is released. Due to the elastic recovery effect of the second spring 31, the second moving block 28 is pushed, causing the second moving block 28 to move downward. Through the contact between the second movable plate 30 and the steel structure, the bottom end of the steel structure inside the movable frame 9 is in close contact with the two ends of the steel structure inside the fixed frame 4.

[0037] Compared with traditional devices, this device uses the elastic force of the second spring 31 to apply a certain downward compressive force to the steel structure by the second movable plate 30, which makes the connection between the steel structures more tightly connected, avoids unstable welding points or misalignment of contact points due to loose contact, improves the stability of welding, and improves welding efficiency.

[0038] like Figure 1 As shown, the fixing block 5 is located on both sides of the fixing frame 4. The fixing block 5 is in the shape of a boss, and the bottom diameter of the fixing block 5 is larger than the top diameter.

[0039] Due to the design of the fixing block 5, the fixing block 5 can play a good limiting role for the first vertical rod 7, making the lifting and lowering movement of the first vertical rod 7 more stable and facilitating the adjustment of the welding and installation angle of the steel structure.

[0040] like Figure 6 As shown, the bottom end of the horizontal plate 17 is fixedly installed with the first vertical plate 18 located on both sides of the first vertical block 10. The first vertical block 10 has a first groove 19 inside, and the limit block 20 is slidably installed inside the first groove 19.

[0041] The design of the first groove 19 can effectively limit the movement of the first vertical plate 18, making the vertical plate 18 and the horizontal plate 17 more stable during lifting and lowering, preventing rotation under the action of the motor 11, and thus facilitating the adjustment of the angle of the movable frame 9.

[0042] like Figure 1 As shown, a second vertical plate 36 is fixedly installed on the top of the housing 2. There are two second vertical plates 36, and welding mechanisms 37 are fixedly installed on the front of both second vertical plates 36.

[0043] Among them, due to the design of the two welding mechanisms 37, two welding points can be welded simultaneously, which improves welding efficiency.

[0044] like Figure 1 and 2 As shown, the bottom of the movable frame 9 is fixedly installed with limiting rods 32 located on the left and right sides of the first vertical rod 7, and the top of the limiting rods 32 is perpendicular to the bottom of the movable frame 9.

[0045] The design of the limiting rod 32 can limit the rotation angle of the movable frame 9. When the movable frame 9 rotates in the opposite direction, the limiting rod 32 will contact the first vertical rod 7, which will make the movable frame 9 horizontal, preventing the movable frame 9 from rotating in the opposite direction and facilitating the welding of the steel structure.

[0046] like Figure 5As shown, a clamping plate 33 is movably installed inside the fixing frame 4, and a rotating block 34 is fixedly installed on the side of the clamping plate 33. The other end of the rotating block 34 passes through the fixing frame 4 and is fixedly installed with a crossbar 35.

[0047] Among them, the rotating crossbar 35, because the outer surface of the rotating block 34 has a threaded groove, the rotation of the rotating block 34 drives the clamping plate 33 to move, and the steel structure is fixed by the opposite movement between the two clamping plates 33.

[0048] like Figure 2 and 6 As shown, the fixed oil pipe 3 has a U-shaped shape, and the hydraulic oil levels at both ends of the fixed oil pipe 3 are equal.

[0049] Among them, due to the design of the fixed oil pipe 3, the principle of communicating vessels is utilized, and through the transmission effect of hydraulic oil, the two ends of the fixed oil pipe 3 are subjected to the same force, thereby achieving synchronous adjustment.

[0050] Working principle and usage process:

[0051] The elastic force of the second spring 31 causes the second movable plate 30 to apply a certain downward compressive force to the steel structure, making the connection between the steel structures more tightly connected.

[0052] The operation of motor 11 causes the rotating plate 13 to push the first movable plate 16 downward through the second vertical rod 15. By squeezing the hydraulic oil inside the fixed oil pipe 3, the first vertical rods 7 on both sides move upward synchronously.

[0053] The operation of motor 11 causes rotating plate 13 to rotate in the opposite direction, which in turn drives first movable plate 16 and horizontal plate 17 to move upward. Through the transmission action of connecting rod 25, the two cleaning blocks 22 are pushed to move in opposite directions.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
