Description

Technical Field

[0001] This utility model relates to the field of chimney installation technology, and in particular to a detachable on-site assembly and welding fixture for chimney bodies. Background Technology

[0002] The chimney body refers to the main vertical part of the chimney, which is the tall, upright tubular structure we usually see. It is the core part of the chimney, and its main function is to generate draft and discharge flue gas into the air high enough for atmospheric diffusion and dilution, thereby reducing the impact on the ground environment and people.

[0003] To accommodate factors such as modularity, connection, hoisting, on-site operation, and quality control, existing chimney structures are designed as detachable, on-site assembly structures. Because the chimney structure is designed in sections, its quality is not as good as that of a one-piece chimney structure, and the chimney structure may be damaged or deformed during assembly and use.

[0027] In one embodiment, such as Figures 1-11 As shown,

[0028] A detachable on-site assembly and welding fixture for chimney bodies includes two chimneys 1, which are symmetrically arranged front and rear. Each chimney 1 has an inner cavity with a heat insulation layer composed of several fixing frames 5. Connecting columns 9 are fixedly connected to the front of the front chimney 1 near its four corners, and fixing blocks 10 are fixedly connected to the front of each connecting column 9. Concave plates 14 are fixedly connected to the rear of the rear chimney 1 near its four corners, and two hinge blocks 13 are fixedly connected to the rear of each concave plate 14. The two hinge blocks 13 are positioned on the left and right sides respectively. The two hinge blocks 13 are symmetrically arranged on the right. Each of the two hinge blocks 13 is hinged to a clamping block 11. The corresponding side of each clamping block 11 is in contact with the outside of the fixing block 10. The corresponding side of each clamping block 11 is provided with a semi-circular groove. The two semi-circular grooves are in contact with a meshing block 17. The inner cavity of the meshing block 17 is provided with a threaded groove. The upper and lower sides of the meshing block 17 are fixedly connected to a circular plate 12. The threaded groove meshes with a lead screw 16. The front end of the lead screw 16 is fixedly connected to a central shaft 15. The front end of the central shaft 15 passes through the inner cavity of the concave plate 14.

[0029] The chimney 1 has a circular box 4 inside its cavity, and a cross wheel 18 inside the circular box 4. Several circular holes are opened on the outside of the chimney 1, arranged in a cross shape. A transmission rod 19 passes through the center of the cross wheel 18, and both ends of the transmission rod 19 pass through the inner cavity of the circular box 4. Movable rods 7 are fitted into the circular holes. Support plates 6 are fixedly connected to opposite ends of the movable rods 7, arranged in a cross shape. Connecting blocks 8 are fixedly connected to corresponding sides of the support plates 6. Each side is fixedly connected to a baffle 2. A limit rod is provided on the surface of the round box 4. A rotating plate 20 is sleeved on the outside of the transmission rod 19. A groove is provided on the outside of the rotating plate 20. Two slots are provided on the inner side wall of the groove. The two slots are arranged symmetrically at the top and bottom. A locking block 21 is attached to the slot. A moving rod is fixedly connected to the opposite side of the two locking blocks 21. The opposite ends of the two moving rods pass through the inner cavity of the slot. A spring 3 is sleeved on the outside of the moving rod. A push block 22 is fixedly connected to the surface of the two locking blocks 21.

[0030] Working principle: When the chimney 1 located at the front moves, it can drive several fixed blocks 10 and connecting columns 9 to move forward. When the connecting column 9 is in contact with the two clamping blocks 11, it can drive the lead screw 16 to rotate through the central shaft 15. When the lead screw 16 rotates, it can drive the meshing block 17 to move. When the meshing block 17 moves, it can press the two clamping blocks 11 to move forward. When the two clamping blocks 11 are subjected to external force, they can swing in opposite directions, so that the two clamping blocks 11 fix the fixed block 10. When the operator passes through... The rotating plate 20 can drive the transmission rod 19 to rotate. When the transmission rod 19 rotates, the cross wheel 18 rotates, thereby driving several movable rods 7 to move in opposite directions, thereby driving the support plate 6, connecting block 8 and baffle 2 to move. When the support plate 6 moves, it can support the inner wall of the chimney 1. When the baffle 2 moves, it can be merged. When the rotating plate 20 rotates, the operator can drive two locking blocks 21 to move through two push blocks 22, so that the rotating rod enters the inner cavity of the groove and completes the fixation of the position of the cross wheel 18.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
