Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline technology, and in particular to a fire smoke exhaust pipeline. Background Technology

[0002] The installation of fire exhaust ducts is a crucial part of building construction. Exhaust pipes are typically hoisted from the roof or other locations to guide smoke extraction. During the installation of two exhaust pipes, workers must lift the pipe to be installed by shoulder or lifting it, aligning it with the already installed pipe. Then, bolts and other connectors are used to secure the flanges of the two pipes together. This installation process is time-consuming and labor-intensive, requiring manual control to maintain the two flanges aligned correctly for bolt connection. If there is any shaking during lifting, the through holes in the flanges may become misaligned, preventing the bolts from passing through or causing them to become clamped and unable to be tightened properly.

[0003] The existing technology has problems that require solving, such as the difficulty in raising the exhaust pipe and the inconvenience of proper connection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fire smoke exhaust pipe that addresses the above-mentioned technical deficiencies. This solves the problems of existing technology, such as the difficulty in raising the smoke exhaust pipe and the inconvenience in aligning and connecting it.

[0005] The technical solution adopted by this utility model is: to provide a fire-fighting smoke exhaust duct, including a main body of the duct, the main body of the duct having vertical sidewalls, and further including:

[0006] A positioning shaft is provided on one side of one of the vertical sidewalls of the flue body;

[0007] The mounting bracket is disposed on the other side of one of the vertical sidewalls of the flue body, and the mounting bracket and the positioning shaft are located on the same vertical sidewall;

[0008] A threaded tube is rotatably mounted on the mounting bracket;

[0009] A hook having a hook portion and a threaded portion, the threaded portion being threadedly connected to the threaded pipe;

[0010] When the two flue bodies are installed together, the hook on one flue body is rotatably sleeved on the positioning shaft on the other flue body.

[0011] To further optimize this technical solution, the hook portion is either semi-circular or circular.

[0012] To further optimize this technical solution, the hook is semi-circular, and the positioning shaft and the mounting bracket are provided on both vertical sidewalls of the flue body.

[0013] To further optimize this technical solution, the mounting bracket has a protective rod, and the end of the protective rod has a positioning ring. One end of the threaded tube is rotatably sleeved in the positioning ring. When the threaded part passes through the threaded tube, the protective rod is located next to the threaded part.

[0014] To further optimize this technical solution, the end of the flue body has a flange, and the lower end of the flange near the positioning shaft has an outwardly protruding support edge, which is used to support the flange of another flue body.

[0015] To further optimize this technical solution, the mounting bracket is either welded to the flue body or detachably mounted on the flue body.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The hook is installed on the threaded pipe, that is, on one side of the flue body. The other side of the flue body is equipped with a positioning shaft. When the two flue bodies are installed together, the hook is hooked on the positioning shaft, which is the rotation axis. That is, the flue body to be installed is hung at an angle or vertically below the flue body that has been fixedly installed above. Then, by supporting one end of the flue body, it is rotated and raised. Through the hanging structure, the lifting force can be reduced, and the rising process is more stable, reducing the control force and saving more effort.

[0018] 2. After the two flue bodies are facing each other, the two flanges abut and align. Then, rotate the threaded pipe and hook to pull the two flue bodies together for initial fixation. Maintain the flanges facing each other to reduce errors and minimize manual force control. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between 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.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figure 1-7As shown, a fire-fighting smoke exhaust duct includes a flue body 1, which has a vertical sidewall 101, and further includes: a positioning shaft 2, disposed on one side of one vertical sidewall 101 of the flue body 1; a mounting bracket 3, disposed on the other side of one vertical sidewall 101 of the flue body 1, with the mounting bracket 3 and the positioning shaft 2 located on the same vertical sidewall 101; a threaded pipe 4, rotatably mounted on the mounting bracket 3; and a hook 5, which has a hook portion 501 and a threaded portion 502, the threaded portion 502 being threadedly connected to the threaded pipe 4. When two flue bodies 1 are installed together, the hook portion 501 on one flue body 1 is rotatably fitted onto the positioning shaft 2 on the other flue body 1. The hook portion 501 is semi-annular or circular.

[0032] In use, when positioning shafts 2 and mounting brackets 3 are respectively installed at both ends of a vertical sidewall 101 of the flue body 1, the hook 501 of the hook 5 can be annular. The flue body 1 to be installed is placed vertically, facing upwards towards the positioning shaft 2 of the upper flue body 1. The hook 5 is inserted from the side of the upper positioning shaft 2 to complete the hanging. Then, the lower end of the flue body 1 is lifted from below, causing the flue body 1 to be installed to rotate upwards, with the two flue bodies 1 facing each other. After rotating upwards, if there is a gap between the flange 102 of the flue body 1 to be installed and the flange 102 of the upper fixed flue body 1, the two flue bodies 1 can be brought closer together to abut. While adjusting to keep the two flanges 102 facing each other, screw the threaded part 502 of the pilot rail of the threaded pipe 4 into place, tighten the hook 5, and finally tighten and fix the two flue bodies 1, which plays a preliminary fixing role. At this time, the flanges 102 of the two flue bodies 1 can be kept facing each other or can be kept facing each other by the intervention of the worker with a small amount of force, so that the bolts can be inserted into the flanges 102 more smoothly to achieve the connection. After the bolts are connected, the hook 5 can still be kept in the tightened connection state, making the connection more stable.

[0033] The threaded tube 4 is rotatably mounted on the mounting bracket 3, maintaining their axial relative fixation so that the hook 5 can be tightened. The threaded tube 4 can be pentagonal in shape or have a rotating handle, etc., to facilitate quick and powerful rotation of the threaded tube 4.

[0034] The positioning shaft 2 and the mounting bracket 3 are located at the upper and lower parts of the vertical side wall 101, which makes it easy to hang the flue body 1 to be installed and rotate it upwards.

[0035] Furthermore, the hook 501 is semi-circular, and positioning shafts 2 and mounting brackets 3 are provided on both vertical sidewalls 101 of the flue body 1.

[0036] In use, positioning shafts 2 and mounting brackets 3 are respectively set on both sides of a vertical sidewall 101 (i.e., both sides in the direction of communication of the flue body 1). The flue body 1 can be hung and installed, and initially positioned, by means of hooks 5. The same setup is made on two vertical sidewalls 101. Each vertical sidewall 101 is equipped with a positioning shaft 2 and a mounting bracket 3, and the mounting brackets are connected to hooks 5 through threaded pipes 4. At this time, the hook part 501 of the hook 5 can be a semi-circular or "C" shaped semi-encircling structure to achieve hanging. The hooks 5 on both sides are hung on the positioning shafts 2 on both sides respectively. The hanging is more stable. Finally, when the hooks 5 are tightened, the force on both sides is more balanced and the connection is more stable.

[0037] Furthermore, the mounting bracket 3 has a protective rod 301, and the end of the protective rod 301 has a positioning ring 302. One end of the threaded tube 4 is rotatably sleeved in the positioning ring 302. When the threaded part 502 passes through the threaded tube 4, the protective rod 301 is located beside the threaded part 502. The mounting bracket 3 is welded to the flue body 1 or detachably mounted on the flue body 1.

[0038] In use, the mounting bracket 3 is fixed to the flue body 1. When the threaded tube 4 is screwed into the threaded part 502, the portion of the threaded part 502 protruding from the threaded tube 4 is shielded by the protective rod 301, which protects the threaded part 502 and reduces stress displacement or damage. Multiple protective rods 301 can be arranged in a ring around the threaded part 502, or the protective rod 301 can be a sleeve structure, gapped around the outside of the threaded part 502. The positioning ring 302 has an annular groove inside, and the end of the threaded tube 4 is rotated and fitted into the groove to achieve axial relative fixation.

[0039] Furthermore, the end of the flue body 1 has a flange 102, and the lower end of the flange 102 near the positioning shaft 2 has a protruding support edge 103, which is used to support the flange 102 of another flue body 1.

[0040] When in use, the support edge 103 protruding from the lower end of the flange 102 near the positioning shaft 2 can support the flange 102 of another flue body 1 from below. When the two flue bodies 1 are connected, the support edge 103 bears part of the weight of the flue body 1 to be installed and forms a limit below. During the tightening of the hook 5, the flue body 1 is more stable and it is easier to connect and install.
