Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heating furnace, concretely to a light -duty tubular heating furnace. BACKGROUND

[0002] The tubular heating furnace is a process heating furnace used in the industries of petroleum refining, petrochemical industry, coal chemical industry, tar processing and crude oil transportation. The flowing medium of the heated substance in the pipe is gas or liquid, and all of them are flammable and explosive substances. The operating conditions are harsh, and the heating method is directly affected by fire. The tubular heating furnace is operated continuously for a long period of time.

[0003] Through the patent inspection, a light -duty tubular heating furnace with publication number CN220380252U is found. The heat insulation plate is fixed on the outer side of the stairs. The high temperature is separated from the foot through the heat insulation plate. The outer side of the handrail is provided with a heat insulation strip. The high temperature on the outer side of the handrail is separated from the hand through the heat insulation strip. Thus, the problem that the worker is scalded and cannot work due to the unawareness of the worker during climbing is avoided. However, the surface of the stairs and the handrail and the stairs is quickly aged after a long time of rain and sun exposure, which causes the heat insulation effect to be lost, and the unaware worker may still be scalded during climbing, which causes the worker to be unable to work. Therefore, a light -duty tubular heating furnace is proposed to solve or improve the above problems. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a light -duty tubular heating furnace, which solves the problems mentioned in the background.

[0005] The utility model provides the following technical scheme: including base, the operating platform fixed in the top of base, the heating furnace fixed in the top of base, the fence fixed in the top of heating furnace, the fixed column fixed on the surface of fence, two groups of fixed column are fixed on the surface of fence, the cover plate is slidably installed in the fixed column, the rack is fixed in the bottom of cover plate, the first connecting arm is rotatably installed in the position of the bottom of fixed column near one side through the pivot, the second connecting arm is rotatably installed in the position of the bottom of fixed column near the other side through the pivot, the tooth block is fixed on the surface of first connecting arm, the tooth block is engaged with the rack, the first connecting column is inserted in the first connecting arm, the second connecting column is inserted in the second connecting arm, and the driving assembly is arranged in the base.

[0006] Further, the driving assembly comprises a driving motor fixed in the base, a threaded rod fixed to the top end of the output shaft of the driving motor, a sliding block slidably mounted on the top of the base, two groups of sliding blocks symmetrically slidably mounted on the top of the base, the threaded rod passing through the inside of the sliding block and being threadedly connected with the sliding block, and a limiting column fixed to the inside of the base near the top side.

[0007] Furthermore, a bearing plate is rotatably mounted on the surfaces of the first and second connecting columns via a rotating shaft. The bearing plate is rotatably connected to both the second and first connecting columns. Several sets of bearing plates are equidistantly mounted on the surfaces of the first and second connecting columns.

[0008] Furthermore, two sets of first connecting arms are symmetrically installed at the bottom of the two sets of fixed columns. The number of first connecting columns is the same as the number of first connecting arms, and the bottom of the first connecting columns is mounted on the top of the slider via a rotating shaft.

[0009] Furthermore, two sets of second connecting arms are symmetrically installed at the bottom of the two sets of fixed columns. The number of second connecting columns is the same as the number of second connecting arms, and the bottom of the second connecting columns is mounted on the top of the slider via a rotating shaft.

[0010] Furthermore, two sets of racks are symmetrically fixed at the bottom of the cover plate, and several sets of toothed blocks are circumferentially fixed on the surface of the first connecting arm.

[0011] Compared with the prior art, this utility model has the following advantages: By setting a cover plate, rack, toothed block and drive assembly, the drive assembly can move the support plate when personnel are not climbing, so that several sets of support plates can be moved to the same vertical position. The drive assembly can also move the cover plate through the rack and toothed block, so that the top of several sets of support plates can be shielded by the cover plate, reducing or avoiding direct sunlight and rain on the support plates.

[0017] 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.

[0018] Please see Figures 1-4 The system includes a base 1, an operating platform 2 fixed to the top of the base 1, a heating furnace 3 fixed to the top of the base 1, the heating furnace 3 being located on one side of the operating platform 2, the structure and function of the operating platform 2 and the heating furnace 3 being the same as those in the aforementioned comparative document, a fence 4 fixed to the top of the heating furnace 3, and fixing posts 13 fixed to the surface of the fence 4, with two sets of fixing posts 13 symmetrically fixed to the surface of the fence 4. A cover plate 5 is slidably installed inside the fixing posts 13, and a rack 16 is fixed to the bottom of the cover plate 5, the rack 16 being located inside the fixing posts 13. A first connecting arm 6 is rotatably installed on the base 13 via a rotating shaft. Near one side of the bottom of the fixed column 13, two sets of first connecting arms 6 are symmetrically installed at the bottom of the two sets of fixed columns 13. Two sets of second connecting arms 8 are rotatably installed at the bottom of the fixed column 13 near the other side via a rotating shaft. The positions of the second connecting arms 8 and the first connecting arms 6 are parallel to each other. A toothed block 17 is fixed to the surface of the first connecting arm 6 and meshes with a rack 16. When the first connecting arm 6 moves, it drives the toothed block 17 to rotate, and when the toothed block 17 rotates, it drives the meshing rack 16 to move. When the rack 16 moves, it drives the fixed cover plate 5 to move. Two sets of racks 16 are symmetrically fixed at the bottom of the cover plate 5. Several sets of toothed blocks 17 are arranged circumferentially on the surface of the first connecting arm 6. The first connecting post 7 is inserted inside the first connecting arm 6, and the number of first connecting posts 7 is the same as the number of first connecting arms 6. The first connecting posts 7 can slide inside the first connecting arm 6. When the first connecting arm 6 rotates, it drives the first connecting posts 7 inserted inside to rotate. The second connecting post 9 is inserted inside the second connecting arm 8, and the number of second connecting posts 9 is the same as the number of second connecting arms 8. The number of 8 is the same. The second connecting post 9 can slide inside the second connecting arm 8. When the second connecting arm 8 rotates, it will drive the second connecting post 9 inserted inside to rotate. The surfaces of the first connecting post 7 and the second connecting post 9 are rotatably mounted with a bearing plate 14 through a rotating shaft. The bearing plate 14 is rotatably connected to both the second connecting post 9 and the first connecting post 7. When the second connecting post 9 and the first connecting post 7 move, they will drive the rotatably connected bearing plate 14 to move. Several sets of bearing plates 14 are equidistantly mounted on the surfaces of the first connecting post 7 and the second connecting post 9. The drive assembly is located inside the base 1.

[0019] The drive assembly includes a drive motor 10 fixed inside the base 1, a threaded rod 11 fixed to the top of the output shaft of the drive motor 10, and a slider 12 slidably mounted on the top of the base 1. Two sets of sliders 12 are symmetrically mounted on the top of the base 1. The bottom of the first connecting post 7 is mounted to the top of the slider 12 via a pivot. When the slider 12 moves, it drives the first connecting post 7 to move, thereby causing the first connecting post 7 to rotate. The bottom of the second connecting post 9 is also mounted to the top of the slider 12 via a pivot. When the slider 12 moves, it drives the first connecting arm 6 to rotate. The movement of the second connecting post 9 causes the second connecting post 9 to drive the second connecting arm 8 to rotate. When the first connecting post 7 and the second connecting post 9 move, they will drive the bearing plate 14, which is rotatably connected to the surface, to move. The threaded rod 11 passes through the interior of a set of sliders 12 and is threadedly connected to the set of sliders 12. When the threaded rod 11 rotates, it will drive the threadedly connected set of sliders 12 to move. The limiting post 15, which is fixed inside the base 1 near the top, passes through the interior of another set of sliders 12 and is slidably connected to it. The limiting post 15 can restrict the position of the sliders 12, reduce or avoid the other set of sliders 12 from tilting and shaking when moving, and improve its stability when moving.

[0020] Working principle: When personnel need to climb to the top of the heating furnace 3 for inspection and maintenance, the drive motor 10 drives the threaded rod 11 to rotate, causing the threaded rod 11 to move a set of sliders 12. The movement of the sliders 12 causes the first connecting column 7 and the second connecting column 9, which are rotatably connected at the top, to move. The movement of the first connecting column 7 and the second connecting column 9 causes the several sets of bearing plates 14, which are rotatably connected to the surface, to move. Because the bearing plates 14 are at different heights between the second connecting column 9 and the first connecting column 7, their movement distances are also different, thus allowing the second connecting column 9 to move. When column 9 and the first connecting column 7 move, they cause several sets of bearing plates 14 to move, forming a staircase. Simultaneously, when the first connecting column 7 moves, it causes the first connecting arm 6 to rotate. The rotation of the first connecting arm 6 causes the fixed toothed block 17 to rotate. The rotation of the toothed block 17 causes the meshing rack 16 to move. The movement of the rack 16 causes the cover plate 5 to move, thus moving the cover plate 5 in the opposite direction to the bearing plate 14. This prevents the cover plate 5 from obstructing the top of the bearing plate 14, hindering people from stepping on it. At the same time, the cover plate 5 itself can also serve as a step for people to climb to the heating area. The furnace 3 is inspected and maintained inside the top enclosure 4. When the maintenance is completed and the support plate 14 is no longer needed, the drive motor 10 reverses and drives the threaded rod 11 to rotate, causing the slider 12 to move in the opposite direction. At this time, the slider 12 will drive the first connecting column 7 and the second connecting column 9 to move in opposite directions, thereby causing the first connecting column 7 and the second connecting column 9 to move the support plate 14. When the first connecting column 7 and the second connecting column 9 move to a position perpendicular to the top of the base 1, several sets of support plates 14 will move to the same vertical position. At the same time, the movement of the first connecting column 7 will drive the second connecting arm 8 to move. When the connecting arm 8 moves, it drives the toothed block 17 to rotate. When the toothed block 17 rotates, it drives the rack 16 to move, which in turn drives the cover plate 5 to move. This causes the cover plate 5 to move to the top side of the support plate 14, thereby shielding the top of several sets of support plates 14. This reduces or prevents the support plates 14 from being directly exposed to sunlight and rain. This avoids the problem that the partitions and heat insulation strips on the surface of the support plates 14 and the second connecting arm 8 will age rapidly after prolonged exposure to rain and sun, causing them to lose their heat insulation effect. This would prevent unsuspecting workers from being burned when climbing on them and being unable to work. The method is relatively convenient to use.

[0021] 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.
