Description

Technical Field

[0001] This utility model relates to the field of steel frame platform technology, specifically a water-cooled wall welded steel frame platform. Background Technology

[0002] The water-cooled wall is the main heat-receiving part of the boiler. It consists of several rows of steel pipes distributed around the boiler furnace. The welding and assembly of the steel pipes of the water-cooled wall is usually carried out on a steel frame platform.

[0003] During the welding of water-cooled walls, multiple steel pipes need to be welded. However, during the welding of the steel pipes in the water-cooled walls, the ends of the steel pipes are easily not neat enough. This results in uneven ends of the welded water-cooled wall steel pipe array, which affects the subsequent assembly of the water-cooled walls and makes it difficult to align the assembled water-cooled walls. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 A steel frame platform for water-cooled wall welding includes a workbench 1. A first slide groove 2 is provided on the workbench 1. A slider 3 is slidably arranged on the first slide groove 2, and there are at least two sliders 3. The sliders 3 are concave. The concave shape of the sliders 3 makes the sliding of the sliders 3 on the first slide groove 2 more stable. The top two ends of the sliders 3 are provided with opposing limiting mechanisms 4. Connecting blocks 6 are fixedly connected to both sides of the sliders 3. The end of the connecting block 6 away from the slider 3 is fixedly connected with a locking mechanism 5. Several locking holes 101 are provided on both sides of the top of the workbench 1. The locking mechanism 5 and the locking holes 101 are engaged to fix the position of the sliders 3.

[0026] The limiting mechanism 4 includes a threaded shaft 401 that passes through the end of the slider 3 and is threadedly assembled with the slider 3. The opposite ends of the two threaded shafts 401 on the slider 3 are rotatably mounted with limiting plates 402, which are used to fix the ends of the steel pipes and facilitate the alignment adjustment of the ends of the two steel pipes.

[0027] The locking mechanism 5 includes a mounting platform 501, the bottom of which contacts the top of the worktable 1. The bottom of the mounting platform 501 is provided with a smooth stainless steel layer. A circular groove 502 is provided inside the mounting platform 501. A sliding shaft 503 is vertically slidably mounted on the mounting platform 501, and the bottom end of the sliding shaft 503 is located inside the circular groove 502. A locking block 504 is fixedly mounted on the bottom end of the sliding shaft 503, and the locking block 504 is slidably connected to the circular groove 502. The locking block 504 is inserted into a locking hole 101. A spring 505 is provided inside the circular groove 502, and the two ends of the spring 505 are fixedly connected to the top of the locking block 504 and the top of the circular groove 502, respectively. The spring 505 pushes the locking block 504 into the locking hole 101, ensuring the locking strength of the locking mechanism 5 and ensuring the firmness of the slider 3 during use.

[0028] The mounting platform 501 is equipped with a locking mechanism 7 at its top. The locking mechanism 7 is used to lock and fix the position of the sliding shaft 503 when it is pulled up. The locking mechanism 7 includes a locking block 701. The top of the mounting platform 501 is provided with a second sliding groove 703. A sliding block 704 slides in the second sliding groove 703. The sliding block 704 is fixedly set at the bottom of the locking block 701. There are two second sliding grooves 703 and two sliding blocks 704. Both the second sliding groove 703 and the sliding block 704 are convex. A fixing plate 702 is fixedly fitted on the sliding shaft 503. The fixing plate 702 is located above the mounting platform 501. The convex design of the second sliding groove 703 and the sliding block 704 prevents the locking block 701 from separating from the mounting platform 501, making the sliding of the locking block 701 more stable.

[0029] Working principle: When using this steel frame platform to weld steel pipes for water-cooled walls, first place the two steel pipes to be welded between the two pairs of limiting mechanisms 4 on the two sliders 3. Then, rotate the threaded shaft 401 to drive the limiting plate 402 to limit and align the ends of the steel pipes. Pull the sliding shaft 503 to drive the locking block 504 to disengage from the locking hole 101. Then slide the locking block 701 so that the locking block 701 is positioned between the fixing plate 702 and the mounting platform 501. Slide the two sliders 3 to make the welding joints of the two steel pipes contact. Then slide the locking block 701 to reset. The spring 505 pushes the locking block 504 to re-engage into the locking hole 101, thereby fixing the sliders 3. Then, the welding operation is carried out on the two steel pipes.

[0030] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
