Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy equipment manufacturing, specifically to the structure of a longitudinally welded boom machine base. Background Technology
[0002] Currently, welding plays a crucial role in the manufacturing of new energy equipment, especially in the production of large and heavy equipment, such as wind turbine towers. However, existing processing products are often large in size and require effective movement and adjustment on the production line, making traditional fixed welding boom machines inadequate for handling such large workpieces. Fixed welding boom machines not only limit the processing flexibility of the workpieces but may also lead to low welding efficiency and inconsistent quality.
[0003] Especially for longitudinal seam welding, since the weld seam is usually long and requires high precision, the welding arm needs to have the ability to move laterally within a certain range to accommodate workpieces of different sizes and shapes. However, existing welding arm machines often lack this flexibility, forcing operators to frequently adjust the position of the workpiece or the angle of the welding arm when producing large workpieces. This not only increases labor intensity but also affects production efficiency and welding quality.
[0004] To address the aforementioned issues, the industry urgently needs a base for a longitudinal seam welding boom machine that can meet the processing requirements of large workpieces. Summary of the Invention
[0005] Therefore, in response to the above problems, this utility model proposes a base structure for a longitudinal seam welding boom machine, which solves the technical problems of insufficient processing flexibility and inability to adapt to the production of workpieces of different sizes and shapes in existing fixed welding boom machines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a longitudinally welded boom machine base structure, including a base plate fixed to the ground, an annular frame on the base plate, and a traveling track on the upper end of the annular frame. The annular frame is rectangular, and multiple inclined support columns are provided on the outer side of the annular frame in the length direction. One end of each inclined support column is connected to the ground, and the inclined support columns, the annular frame, and the ground form a triangular support structure. A ladder is provided on the side of the annular frame in the width direction. The upper end of the ladder is flush with the upper end of the annular frame. A guardrail is provided between the upper end of the ladder and the annular frame, and a grip handle is provided on the guardrail. A flat platform for personnel to stand on is provided on the upper end of the annular frame near the ladder.
[0007] Furthermore, the angle between the inclined support column and the ring frame is 10 to 30 degrees.
[0008] Furthermore, the upper surface of the flat platform is provided with anti-slip texture, and the lower surface of the flat platform is provided with multiple support ridges.
[0009] Furthermore, limit devices are provided at both ends of the traveling track to prevent the flat platform from derailing during the sliding process.
[0010] Furthermore, the limiting device includes a track baffle located at the upper end of the ring frame and a support rib plate located at the upper end of the ring frame and connected to the track baffle, wherein the support rib plate is perpendicular to the track baffle.
[0011] Furthermore, a shock-absorbing mechanism is provided on the inner side of the track baffle. The shock-absorbing mechanism includes multiple hydraulic cylinders connected to the track baffle, shock-absorbing springs sleeved on the piston rods of the hydraulic cylinders, and shock-absorbing plates connected to the piston rods of each hydraulic cylinder. One end of the shock-absorbing spring is connected to the hydraulic cylinder, and the other end of the shock-absorbing spring is connected to the shock-absorbing plate. The oil inlet and oil outlet of the hydraulic cylinder are connected through a connecting pipe.
[0012] Furthermore, the connecting pipes of each cylinder are interconnected through a main pipe, which is equipped with an expansion chamber and a pressure relief valve.
[0013] Furthermore, the flat platform is equipped with a human infrared sensor to detect whether a person is present.
[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0015] 1. This solution designs a longitudinally welded boom crane base, comprising a base plate, a ring frame, a traveling track, inclined support columns, a ladder, guardrails, and a flat platform, effectively improving the base's stability and load-bearing capacity. The inclined support columns, ring frame, and ground form a triangular support structure, enhancing structural stability. Simultaneously, the ladder, guardrails, and grab handles provide operators with safe access and a standing platform. This improves the stability and safety of the boom crane base, ensuring operator safety and facilitating maintenance and inspection.
[0016] 2. This scheme limits the angle between the inclined support column and the ring frame to between 10 and 30 degrees, which ensures the stability of the structure and avoids unnecessary material waste.
[0017] 3. This design incorporates anti-slip textures on the upper surface of the flat platform, improving the operator's standing stability. Simultaneously, multiple support ridges are installed at the lower end of the flat platform, enhancing its load-bearing capacity.
[0018] 4. This design incorporates limiting devices at both ends of the traveling track, including track baffles and supporting ribs, forming a strong support that effectively prevents the flat platform from derailing during sliding. A shock-absorbing mechanism, including hydraulic cylinders, damping springs, and damping plates, is installed inside the track baffles to effectively absorb impact energy and protect the limiting devices from damage. This improves the impact resistance of the limiting devices and extends their service life. Connecting pipes link the hydraulic cylinders together, and an expansion chamber and pressure relief valve are installed on the main pipeline to effectively stabilize the hydraulic pressure and improve the shock absorption effect.
[0019] 5. A human infrared sensor is installed on the flat platform to detect the presence of personnel. When a person stands on the platform, the sensor will send a signal to monitor and detect abnormal situations in a timely manner. Attached Figure Description

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0029] refer to Figures 1 to 6This embodiment provides a base structure for a longitudinal seam welding boom machine, including a base plate 1 fixed to the ground, an annular frame 2 mounted on the base plate 1, and a traveling track 3 mounted on the upper end of the annular frame 2. The annular frame 2 is rectangular, and multiple inclined support columns 4 are provided on the outer side of the annular frame 2 in the length direction. One end of each inclined support column 4 is connected to the ground, and the inclined support column 4, the annular frame 2, and the ground form a triangular support structure. A ladder 5 is provided on the side of the annular frame 2 in the width direction. The upper end of the ladder 5 is flush with the upper end of the annular frame 2. A guardrail 51 is provided between the upper end of the ladder 5 and the annular frame 2. A grip handle 52 is provided on the guardrail 51. A flat platform 6 for personnel to stand on is provided on the upper end of the annular frame 2 near the ladder 5.
[0030] The ring frame 2 is a rectangle formed by connecting multiple channel steels as columns and multiple square steels or channel steels as crossbars.
[0031] The included angle α between the inclined support column 4 and the ring frame 2 is 10 degrees to 30 degrees, preferably 15 degrees.
[0032] A flat platform 6 is installed at the upper end of the ring frame 2 near the ladder 5, serving as a standing area for the operator. There are two platforms 6 when there are two ladders 5. To improve standing stability, anti-slip textures are provided on the upper surface of the platform 6. Simultaneously, multiple support ridges are provided at the lower end of the platform 6 to enhance its load-bearing capacity and reduce deformation.
[0033] Limiting devices are installed at both ends of the traveling track 3 to prevent the flat platform from derailing during sliding. The limiting devices include a track baffle 71 located at the upper end of the ring frame 2 and a supporting rib 72 located at the upper end of the ring frame 2 and connected to the track baffle 71. The supporting rib 72 is perpendicular to the track baffle 71. A shock-absorbing mechanism 8 is installed on the inner side of the track baffle 71. The shock-absorbing mechanism 8 includes multiple hydraulic cylinders 81 connected to the track baffle 71, shock-absorbing springs 82 sleeved around the piston rods of the hydraulic cylinders 81, and shock-absorbing plates 83 connected to the piston rods of each hydraulic cylinder 81. One end of the shock-absorbing spring 82 is connected to the hydraulic cylinder 81, and the other end is connected to the shock-absorbing plate 83. The oil inlet and outlet of the hydraulic cylinder 81 are connected by a connecting pipe 84. When the welding boom moves on the traveling track 3 and approaches the track baffle 71, it will first touch the shock-absorbing mechanism 8, thereby reducing the impact and damage to the base structure. Meanwhile, to optimize the shock absorption effect, the connecting pipes 84 of each hydraulic cylinder 81 are interconnected through a main pipe 85, and an expansion chamber 86 is installed on the main pipe 85, with a pressure relief valve 87 connected to the expansion chamber 86. This design guides the pressure to the expansion chamber 86, ensuring the stability and reliability of the shock absorption mechanism 8 during long-term use.
[0034] The flat platform 6 is equipped with a human infrared sensor 9 to detect the presence of personnel. When a person stands on the flat platform 6, the sensor will emit a signal to promptly monitor and detect abnormal situations. This design ensures that rapid response measures can be taken in emergency situations, protecting the safety of operators.
