Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for gasifier equipment installation, and in particular to a special tool for supporting the transition ring and inner ring of a gasifier. Background Technology

[0002] A gasifier is a device used to convert solid or liquid fuels into syngas (mainly composed of carbon monoxide and hydrogen). It achieves the conversion from fuel to gaseous products through a series of complex chemical reactions under certain temperature, pressure and gasifying agent conditions, causing incomplete combustion or pyrolysis of the fuel.

[0003] The precise installation of the transition ring and inner ring is crucial during the installation and maintenance of a gasifier. Currently, there is a lack of high-precision support tools specifically designed for the transition ring and inner ring of a gasifier. Existing general-purpose support equipment is insufficient to meet the requirements for positioning accuracy and support stability during installation. During installation, improper support often leads to positional deviations between the transition ring and inner ring, affecting key performance aspects such as internal airflow distribution and heat transfer, thereby reducing the overall operating efficiency and service life of the gasifier. Furthermore, general-purpose support tools are cumbersome to operate and inefficient, increasing installation time and labor costs. Therefore, a dedicated support tool for the transition ring and inner ring of a gasifier is proposed to address these issues. Utility Model Content

[0030] 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.

[0031] Reference Figures 1-2 This utility model provides an embodiment of a special tool for supporting the transition ring and inner ring of a gasifier, comprising a circular frame 1. The diameter of the circular frame 1 can be customized according to the inner diameter of the transition ring and inner ring of the gasifier. The circular frame 1 is made of high-strength lightweight alloy material, which reduces the overall weight of the tool while ensuring structural strength, making it easy to handle and install. A bracket 2 is fixedly connected to the top of the circular frame 1, which facilitates the installation of a laser rangefinder and an angle sensor. A positioning pointer 3 is fixedly connected to the top of the circular frame 1, which can be aligned with a preset positioning mark inside the gasifier to ensure accurate initial installation position of the support tool. A support mechanism 4 is provided on the outer wall of the circular frame 1.

[0032] Reference Figures 2-4The support mechanism 4 includes a positioning plate 402. A rotating rod 405 is rotatably connected to the inner wall of the positioning plate 402. The side of the rotating rod 405 away from the positioning plate 402 is a threaded surface, and the side closer to the positioning plate 402 is an arc surface. The rotating rod 405 can rotate within a certain angle range to adapt to different installation spaces and angle requirements. A connecting plate 404 is fixedly connected to the outer wall of the rotating rod 405. The two move along the same trajectory. Fasteners are provided on the threaded surface of the rotating rod 405 to fix the rotating rod 405. A fixing screw 401 is fixedly connected to the side of the connecting plate 404 away from the circular frame 1. The outer wall is threaded with a connecting arm 403. The length between the fixing screw 401 and the connecting arm 403 can be adjusted to adapt to different installation requirements. The inner wall of the connecting arm 403 away from the circular frame 1 is threaded with a threaded rod 408. The side of the threaded rod 408 away from the connecting arm 403 is fixedly connected with a rubber block 407. The threaded rod 408 allows for more precise adjustment, and the rubber block 407 increases the friction with the transition ring or inner ring surface to prevent slippage. The inner wall of the connecting arm 403 is provided with a fixing mechanism 5 to prevent the connecting arm 403 from loosening.

[0033] Reference Figures 2-4 The fasteners include a nut 406, whose inner arc surface is threaded onto the threaded surface of the rotating rod 405. The side of the nut 406 facing the connecting plate 404 contacts the outer wall of the positioning plate 402. The nut 406 is used to fix the rotating rod 405. The outer wall of the positioning plate 402 is fixedly connected to the outer arc surface of the circular frame 1. The two are fixed together to fix the positioning plate 402. The side of the rotating rod 405 near the fixing screw 401 is T-shaped. The T-shape prevents the rotating rod 405 from falling off when it rotates. The threaded rod 408 has a higher precision than the fixing screw 401. The threaded rod 408 is used to achieve precise adjustment.

[0034] Reference Figures 3-4 The fixing mechanism 5 includes an adjusting screw 501, with a movable block 502 rotatably connected to the bottom end of the adjusting screw 501. The rotation of the adjusting screw 501 drives the movable block 502 to move. A rubber pad 503 is fixedly connected to the bottom end of the movable block 502. The two move along the same trajectory. The bottom end of the rubber pad 503 contacts the threaded groove of the fixing screw 401. The contact setting prevents the connecting arm 403 from rotating. The outer wall of the adjusting screw 501 is threadedly connected to the inner wall of the connecting arm 403. The threaded connection achieves a fixing effect. The outer wall of the movable block 502 is slidably connected to the inner wall of the connecting arm 403. A guide groove is provided on the inner wall of the connecting arm 403 to facilitate the vertical movement of the movable block 502.

[0035] Working principle: The special support tool is placed inside the gasifier. The positioning pointer 3, fixedly connected to the top of the circular frame 1, is aligned with the pre-set positioning mark inside the gasifier. This operation accurately determines the initial installation position of the support tool, laying a good foundation for subsequent support work. The rotating rod 405 can rotate flexibly within a certain angle range to adapt to different installation spaces and angle requirements. After the rotating rod 405 is adjusted to the appropriate angle, the inner arc thread of the fastener nut 406 is connected to the threaded surface of the rotating rod 405, ensuring that the side of the nut 406 facing the connecting plate 404 is in close contact with the outer wall of the positioning plate 402, thus firmly fixing the rotating rod 405. Since the connecting plate 404 is fixedly connected to the rotating rod 405, once the position of the rotating rod 405 is determined, the connecting plate 404 is also fixed. The fixing screw 401 and connecting arm 403, which are fixedly connected to the connecting plate 404, are threaded together. By rotating the connecting arm 403, the length between it and the fixing screw 401 can be adjusted to meet different installation requirements and complete the initial position adjustment of the support mechanism 4. After the initial adjustment, if more precise adjustment is required, it can be achieved by rotating the threaded rod 408. Because the precision of the threaded rod 408 is greater than that of the fixing screw 401, the rubber block 407 fixedly connected to one end of it is made of rubber, which can increase the friction with the transition ring or inner ring surface and prevent slippage during the support process. By rotating the threaded rod 408, precise fine-tuning of the support position can be achieved.

[0036] To prevent the connecting arm 403 from loosening during support, the fixing mechanism 5 plays a crucial role. Rotating the adjusting screw 501, whose outer wall is threadedly connected to the inner wall of the connecting arm 403, drives the movable block 502, which is rotatably connected to its bottom end, to move vertically within the guide groove on the inner wall of the connecting arm 403. The rubber pad 503, fixedly connected to the bottom end of the movable block 502, moves along with it. When the bottom end of the rubber pad 503 contacts the threaded groove of the fixing screw 401, it generates significant friction, effectively preventing the connecting arm 403 from rotating relative to the fixing screw 401, thus ensuring the stability and reliability of the support tool during operation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
