Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding auxiliary equipment, in particular to a welding platform frame for welding a penstock. Background Art

[0002] When carrying out the welding operation of multiple layers of welds with long distances for large-diameter pressure pipelines, it is often necessary for workers to drill into the pipeline to assist the welding robot in welding operations. This is because although the existing welding robots can automatically perform welding work, they still require manual cooperation to check their work progress and welding quality. Moreover, the welding robots and their supporting equipment (such as welding power sources, wire feeding devices, distribution boxes, etc.) also need manual assistance for transportation and simple maintenance.

[0003] Currently, in order to facilitate workers to carry out the above work, a welding operation platform that can move inside the pipeline is usually set inside the large-diameter pressure pipeline. Through this platform, when the welding robot is performing pipeline welding work, workers can stand on the platform to check its work progress and welding quality; at the same time, the transportation and simple maintenance of the welding robot and its supporting equipment can also be completed on the platform.

[0004] However, the existing welding operation platforms have simple structures, resulting in the welding robots and their supporting equipment being randomly placed everywhere on the platform, leading to chaotic equipment placement, and frequently causing problems such as being unable to find equipment in time, mutual collision and damage between equipment, and workers being injured by bumping into equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a welding platform frame for welding a penstock. By designing independent equipment placement areas and personnel operation areas, this platform frame avoids the problem of random equipment placement and reduces the mutual interference between equipment and workers.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a welding platform frame for welding a penstock, including an equipment placement rack and a personnel operation platform rack arranged in sequence along the pipeline extension direction. The equipment placement rack is welded and connected to the personnel platform rack, and multiple walking wheels are provided at the bottom of the equipment placement rack, and guide wheels are provided on both sides at the bottom of the personnel operation platform rack.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0022] Example: The specific embodiments of this utility model are as follows: Figure 1 , 2 As shown in Figures 5 and 6, a welding platform frame for welding pressure steel pipes includes an equipment placement frame 1 and a personnel work platform frame 2 arranged sequentially along the pipe extension direction. The equipment placement frame 1 and the personnel work platform frame 2 are connected by welding. Furthermore, the bottom of the equipment placement frame 1 is provided with multiple traveling wheels 14 that roll in contact with the inner wall of the bottom of the pipe, and both sides of the bottom of the personnel work platform frame 2 are provided with guide wheels 213 that roll in contact with the inner wall of the side of the pipe. In this embodiment, both the traveling wheels 14 and the guide wheels 213 are existing casters with braking devices. This caster structure is well-known to those skilled in the art, therefore its structure will not be described in detail.

[0023] When using this platform, workers first place various welding equipment in an orderly manner on the equipment placement frame 1. Then, using a trolley to pull or manually pushing, the platform is moved along the pipeline's extension direction to the welding location. Next, the worker removes the welding robot and performs various pre-welding preparations. Afterward, the worker supervises the welding robot on the personnel work platform 2 to automatically complete the welding work. After welding is completed, the worker puts the welding robot back on the equipment placement frame 1 and repeats the aforementioned work process. During this process, the worker can check the welding robot's progress and welding quality through the personnel work platform 2 and perform simple maintenance on the welding robot and its supporting equipment when necessary.

[0024] Compared to the current rudimentary welding platforms, this platform frame is welded together from an equipment placement frame 1 and a personnel work platform frame 2. This means the platform frame is designed with separate equipment placement and personnel work areas, thus avoiding the problem of haphazardly stacking equipment. This facilitates the retrieval and placement of equipment by workers and reduces the chance of worker and equipment collisions and injuries. Furthermore, the platform frame uses casters 14 to contact the bottom inner wall of the pipe and guide wheels 213 to contact the side inner wall of the pipe, allowing for easy overall movement and stable movement within the pipe. This reduces swaying during movement, thereby lowering the risk of equipment falling and improving safety.

[0025] In this embodiment, the specific structure of the equipment placement rack 1 is as follows: Figure 3As shown in the figure: The equipment placement rack 1 is in a "convex" shape, and the overall equipment placement rack 1 is of a frame structure. Among them, a bottom plate 11, an intermediate plate 12, and a top plate 13 for placing various welding equipment are horizontally arranged in sequence from bottom to top inside the frame-structured equipment placement rack 1. Specifically: Both sides of the bottom plate 11 are set as placement areas a for placing the wire feeding device 5, and the side of the placement area a away from the personnel operation platform rack 2 is set as a placement area b for placing the shielding gas cylinder 7. Both sides of the intermediate plate 12 are set as placement areas c for placing the automatic welding robot 3, and a relief notch for avoiding the shielding gas cylinder 7 is provided on the side of the placement area c away from the personnel operation platform rack 2; the middle part of the intermediate plate 12 is set as a placement area d for placing the welding power source 4. The top plate 13 is set as a placement area e for placing the distribution box 6.

[0026] Through the settings of each placement area, the automatic welding robot 3, the welding power source 4, the wire feeding device 5, the distribution box 6, and the shielding gas cylinder 7 can be neatly and orderly placed on the equipment placement rack 1. Thus, the staff can very conveniently find each welding equipment, and at the same time, it also reduces the probability of mutual collision and damage between the equipment and the probability of workers bumping into the equipment and getting injured. In this embodiment, the automatic welding robot 3 uses the A-390 type trackless intelligent welding robot of our company; the welding power source 4 uses the DPS-500Max type fully digital multi-functional welding machine of our company; the wire feeding device 5 uses the XG-96A type wire feeding device of our company; the rest of the equipment is publicly known products, so no further detailed introduction will be made.

[0027] Regarding the specific structure of the personnel operation platform rack 2, as Figure 4 shown: The personnel operation platform rack 2 includes two circular arch frames 21 arranged vertically in sequence along the pipeline extension direction. Oblique support rods 211 inclined towards the middle are provided on both sides of the inner circle of the circular arch frame 21. The upper ends of the oblique support rods 211 are connected to a horizontal support rod 212, and both ends of the horizontal support rod 212 are respectively connected to both sides of the circular arch frame 21. Thus, the oblique support rods 211 can be combined with the horizontal support rod 212 to form a triangular support structure, making a single circular arch frame 21 have good support. At the same time, two detachable connecting rods 23 and one fixed connecting rod 22 arranged horizontally from top to bottom are fixedly connected between the two oblique support rods 211 on the same side. This connects the two circular arch frames 21 into one body, further improving the firmness of the entire personnel operation platform rack 2.

[0028] Meanwhile, to provide a working platform, a main platform plate 24 is horizontally positioned between the two arched frames 21, with both ends of the main platform plate 24 mounted on two detachable connecting rods 23 at the same horizontal height. There are several ways to connect the main platform plate 24 to the detachable connecting rods 23, such as: the main platform plate 24 can have a groove cut into its lower surface and then overlap the detachable connecting rod 23; or the main platform plate 24 can have a through hole for the detachable connecting rod 23 to pass through. Additionally, auxiliary platform plates 25 are provided on both sides above the main platform plate 24, and the edges of the auxiliary platform plates 25 are welded to the horizontal support rods 212 on the two arched frames 21. Workers can easily access the main platform plate 24 via the detachable connecting rods 23 and the fixed connecting rods 22. Furthermore, the arched frames 21 on both sides also prevent workers from falling off the platform.

[0029] In this embodiment, both ends of the detachable connecting rod 23 are connected through the diagonal support rod 211 and are locked onto the diagonal support rod 211 with nuts. This design facilitates the removal of the main platform plate 24 from one height of the detachable connecting rod 23 and its transfer to another horizontal height of the detachable connecting rod 23, thereby meeting the different height requirements of the workers for the main platform plate 24.

[0030] In addition, regarding the specific installation position of the guide wheel 213, in this embodiment, the guide wheel 213 is installed on the lower end of the inclined support rod 211.

[0031] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
