All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] As Figure 1-10 shown, a ship exhaust pipe installation device provided in this embodiment of the present invention includes several sets of installation mechanisms;

[0029] The installation mechanism includes a lower movable support frame 4, an adjusting plate 5, and an upper movable support frame 6; the upper movable support frame 6 includes a first angle steel 601 and a second angle steel 602, one end of the first angle steel is fixedly connected to one end of the second angle steel, so that the upper movable support frame forms an inverted L-shaped structure; the lower movable support frame 4 includes a third angle steel 401 and a fourth angle steel 402, one end of the third angle steel is fixedly connected to one end of the fourth angle steel, so that the lower movable support frame forms an L-shaped structure; one end of the adjusting plate is fixedly connected to one end of the lower movable support frame 4, and the other end of the lower movable support frame 4 is connected to the expansion joint flange 7;

[0030] A first adjustment long hole 8 and a second adjustment long hole 9 are respectively provided on the second angle steel and the adjusting plate, and the second angle steel and the adjusting plate are connected through the first adjustment long hole and the second adjustment long hole, so that the distance between the lower movable support frame 4 and the upper movable support frame 6 is adjustable;

[0031] During specific installation, taking the above-mentioned movable support frame 6 as an example, as Figure 3 shown, the left side of the first angle steel 601 is connected to the top of the second angle steel 602 by welding. Before welding, it can be considered to cut off the panel of the butt joint part between the top end of the second angle steel 602 and the first angle steel, leaving only the web, and butt-welding it with the first angle steel to form an integral body; and, in order to reduce the weight, it can be considered to perform chamfering treatment on the first angle steel 601 and the second angle steel 602; and, the adjusting plate 5 also uses angle steel and covers the outer surfaces of the second angle steel and the fourth angle steel.

[0032] When installing the ship's exhaust pipe, an expansion joint is installed between adjacent exhaust pipes, and the expansion joint is fixedly connected to the exhaust pipe flange A through the expansion joint flange. A number of sets of the installation mechanism are arranged along the circumferential direction of the expansion joint flange.

[0033] Specifically, as Figure 1 、 4 、7 shown, the first angle steel is provided with a first mounting hole 10, the third angle steel is provided with a third mounting hole 11, the upper movable support frame is connected to one side of the expansion joint flange through the first mounting hole, and the lower movable support frame is connected to the other side of the expansion joint flange through the third mounting hole; as Figure 6 、 9 shown, the fourth angle steel and the adjusting plate are respectively provided with a first fixing hole 12 and a second fixing hole 13, and the fourth angle steel and the adjusting plate are connected through the first fixing hole and the second fixing hole.

[0034] As Figures 1 to 10As shown in the figure, the installation mechanism in this embodiment is composed of upper and lower movable support frames and an adjustment plate. The design principle is as follows: The upper and lower movable support frames are connected to the adjustment plate. The adjustment bolt 2 passes through the first adjustment long hole 8 of the upper movable support and the second adjustment long hole 9 of the adjustment plate, and the fixing bolt 1 passes through the fourth angle steel and the first fixing hole 12 and the second fixing hole 13 on the adjustment plate to connect the fourth angle steel and the adjustment plate. After the installation mechanism is pre-adjusted to the inner spacing of the expansion joint flange, it is connected to the flanges on both sides of the expansion joint in sequence. Then, the distances at the four points of the upper, lower, left, and right of the expansion joint are measured. If the original values set by the manufacturer cannot be achieved, the upper, lower, left, and right distances of the expansion joint are adjusted along the center direction of the waste gas pipe by using the long holes of the adjustment plate and the upper movable support frame until the requirements are met. Then, the adjustment and fixing bolts 2 are tightened, and the adjustment plate and the upper and lower movable support frames form a whole. Each expansion joint is first connected to an adjacent waste gas pipe, and then 3 to 4 installation mechanisms are evenly arranged along the circumference of the expansion joint flange. The movable support frame is fixed by using the expansion joint connection bolt 3. After adjusting the expansion joint spacing according to the manufacturer's requirements, the adjustment and fixing connection bolts 3 are tightened. Then, another adjacent waste gas pipe is connected, and the movable support frame is fixed by using the expansion joint connection bolt. The waste gas pipeline supports the expansion joint installation device in this way in sequence to ensure that the center of the waste gas pipeline does not deform and plays a role in fixed support. The installation procedure during construction is: waste gas pipe → expansion joint → expansion joint installation device → waste gas pipe. After the installation device is constructed, it is transported to the general assembly together with the segments. After the general assembly is closed, the installation device is removed. When removing, first remove the adjustment bolt and the fixing bolt, take off the adjustment plate, then loosen the expansion joint connection bolt for fixing the installation device, and take off the upper and lower movable support frames, and then tighten the connection bolts between the waste gas pipe and the expansion joint again.

[0035] In summary, the installation device for the ship's waste gas pipe of the present application is simple, small, easy to manufacture, low in cost, easy to install, and can be popularized to other ship projects. In the present application, the lower movable support frame 4 and the upper movable support frame 6 are arranged inside the expansion joint, and the combination plays a role in fixed support. After the adjustment plate 5 and the upper and lower movable support frames are adjusted in place, they are fixed, connecting the adjustment plate and the upper and lower movable support frames into a whole, playing a role in supporting the expansion joint and preventing deformation. By using the adjustment bolt and the fixing bolt, the upper and lower movable support frames are adjusted during the positioning process of the expansion joint to ensure the correct positioning of the expansion joint and the unchanged center of the exhaust gas pipeline.

[0036] Finally, it should be pointed out that: The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
