DETAILED DESCRIPTION

[0020] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings.

[0021] Referring to Figs. 1-2 shown; The embodiment discloses a power combined pipe rack connecting installation structure, which comprises: Pipe rack 10; The pipe rack 10 is spliced by any number of pipe rack modules 1; The pipe rack module 1 is provided with a power pipe through hole 105 in the center, and an inner pipe 106 is plugged and fixed in the power pipe through hole 105 of the pipe rack module 1, and the power pipe is plugged into the inner pipe 106; The adjacent pipe rack modules 1 are spliced into one through a splicing structure, and the adjacent pipe rack modules 1 are fixed through the connecting pieces arranged in the plug-in direction of the pipe rack module 1 after splicing. When the spliced pipe rack 10 has a splicing notch 11, the two adjacent pipe rack modules 1 of different heights are connected through a transition connecting piece 4.

[0022] Specifically, the embodiment discloses a modularized pipe rack structure which can be combined into different forms according to the arrangement requirements of the power pipe through a corresponding number of pipe rack modules 1. Meanwhile, according to the splicing mode and the connecting piece 3 of the adjacent pipe rack modules 1, the stability of the adjacent pipe rack modules 1 and the stability of the whole pipe rack 10 after connection can be ensured.

[0023] Preferably, the pipe rack module 1 of the embodiment comprises a module body, a power pipe through hole 105 is processed in the center of the module body; the outer periphery of the module body is uniformly divided into four module connecting surfaces through circular segment parts, and the adjacent module bodies are spliced into a whole through the splicing structure of the corresponding module connecting surfaces.

[0024] Firstly, the embodiment further limits the structure of the pipe rack module 1, which comprises a module body, the center position of the module body is designed as a power pipe through hole 105, and an inner pipe 106 is fixed in the power pipe through hole 105; preferably, the opening size of the inner pipe 106 and the power pipe through hole 105 of the embodiment is matched, at the same time, in order to better position and improve the connecting structure of the inner pipe 106 and the power pipe through hole 105, a plurality of positioning grooves can be arranged on the inner wall of the power pipe through hole 105 in the circumferential direction, at the same time, a plurality of positioning protrusions are arranged on the outer wall of the inner pipe 106, when installing, the inner pipe 106 can be guided and positioned through the cooperation of the positioning protrusions and the positioning grooves. Finally, the power pipe can be inserted.

[0025] Preferably, the outer periphery of the module body of the embodiment is respectively provided with a first module connecting surface 101, a second module connecting surface 102, a third module connecting surface 103 and a fourth module connecting surface 104 in a clockwise direction; The splicing structure of the embodiment comprises: The insertion groove 107 located at the first module connecting surface 101 and the fourth module connecting surface 104; and The insertion protrusion 108 located at the second module connecting surface 102 and the third module connecting surface 103, the insertion protrusion 108 can be inserted into the insertion groove 107 in the thickness direction of the pipe rack module 1; The connecting piece 3 is fixed on both sides of the thickness direction of the adjacent pipe rack module 1, and the connecting pieces 3 located on both sides of the thickness direction of the pipe rack module 1 are connected through a plurality of bolts.

[0026] Firstly, the connection between the modular pipe rack modules 1 of the embodiment adopts a splicing manner, and the splicing direction is the thickness direction of the module body. Since the power pipe needs to be filled and tamped after being laid, in order to avoid the sliding and separation between the spliced pipe rack modules 1 caused by the vertical stress, the insertion direction of the pipe rack modules 1 of the embodiment is designed as the thickness direction of the module body. After the insertion of the insertion protrusions 108 and the insertion grooves 107 in the thickness direction of the module body, the corresponding module connecting surfaces can be aligned.

[0027] Since the insertion direction of the module body of the embodiment is the thickness direction, the thickness direction of the module body needs to be constrained after splicing to avoid displacement between the module bodies. Specifically, the edge position of the module abutting surface of the module body of the embodiment is the mounting area of the connecting piece 3. The connecting piece 3 is a plate structure of hard material. The mounting area is processed with a light hole for the bolt to pass through, and the inner diameter of the light hole is larger than the maximum outer diameter of the bolt. The bolt passes through the two connecting pieces 3, and the other end of the bolt is fastened by a nut. The two connecting pieces 3 are used to constrain the displacement of the thickness direction of the adjacent pipe rack modules 1.

[0028] The front surface and the back surface of the connecting surface of the two adjacent module bodies of the embodiment are the mounting areas of the connecting pieces 3. At the same time, the width of the connecting piece 3 is designed to ensure that it can be connected with the side surfaces of the two module bodies at the same time, and the mounting space of the bolt is reserved. The connection of the bolt adopts the mode of opening a light hole in the module body, which can facilitate the passing and mounting of the bolt. Only the nut on the outside of the connecting piece 3 on the other side is needed to fasten the bolt.

[0029] Preferably, the transition connecting piece 4 of the embodiment is arranged between the two adjacent module bodies with height difference at the splicing gap 11. The transition connecting piece 4 is connected with the fourth module connecting surface 104 of the module body above and the first module connecting surface 101 of the module body below, respectively. The transition connecting piece 4 is connected with the corresponding module connecting surface by the bolt.

[0030] Secondly, the transition connecting piece 4 of the embodiment is an L-shaped structure as a whole. The transition connecting piece 4 comprises: The transition first plate 401 connected with the fourth module connecting surface 104 of the module body above; and The transition second plate 402 connected with the first module connecting surface 101 of the module body below. The first protruding part 403 is protruded from the transition first plate 401 to the insertion slot 107 of the fourth module connecting surface 104, and the number and size of the first protruding part 403 are matched with the insertion slot 107 of the fourth module connecting surface 104. The second protruding part 404 is protruded from the transition second plate 402 to the insertion slot 107 of the first module connecting surface 101, and the number and size of the second protruding part 404 are matched with the insertion slot 107 of the first module connecting surface 101.

[0031] The first module connecting surface 101 and the fourth module connecting surface 104 are designed as the structure with the insertion slot 107, and the second module connecting surface 102 and the third module connecting surface 103 are designed as the structure with the insertion protrusion 108. Therefore, when the power pipe rack is arranged with the gap 11, the transition connecting piece 4 of the embodiment can be directly connected through the first module connecting surface 101 and the fourth module connecting surface 104. Specifically, the transition connecting piece 4 is positioned and located through the first protruding part 403 of the transition first plate 401 and the insertion slot 107 of the first module connecting surface 101, and then is fastened by bolts. Secondly, the transition connecting piece 4 is positioned and located through the second protruding part 404 of the transition second plate 402 and the insertion slot 107 of the fourth module connecting surface 104, and then is fastened by bolts.

[0032] Specifically, when the transition connecting piece 4 of the embodiment is arranged between two adjacent module bodies, the transition connecting piece 4 is connected with the corresponding module body through the bolts passing through the first protruding part 403 and the second protruding part 404.

[0033] When the pipe rack 10 is completed by splicing the pipe rack modules 1, the side surfaces extending in the vertical direction are formed on both sides of the pipe rack 10. Therefore, in order to strengthen the structure of the area, at least two module bodies arranged along the vertical direction of the pipe rack 10 and located at the outermost side of the pipe rack 10 are connected by the side sealing plate 5 in the design of the embodiment.

[0034] Preferably, the side sealing plate 5 of the embodiment comprises: a sealing plate 501 matched with the total length of the module body at the outermost side of the pipe rack 10; and a third protruding part 502 protruded from the sealing plate 501; The side sealing plate 5 is connected to one side of the fourth module connecting surface 104 of the plurality of module bodies, and the third protruding part 502 is embedded in the corresponding insertion slot 107. The side sealing plate 5 is connected with the corresponding module body through the bolts passing through the third protruding part 502.

[0035] Meanwhile, it needs to be explained that in order to adapt to the installation of the side of the row pipe frame 10 with the plug-in protrusion 108, the side sealing plate 5 on this side is designed to have a split structure, which avoids the corresponding plug-in protrusion 108 by being split into multiple sealing plates, and then is fixed by bolt assembly respectively. Similarly, when the gap 11 of the spliced row pipe frame 10 is located on the side of the second module connecting surface 102, the connecting piece 3 at this position can also adopt a split structure.

[0036] In the above technical solution, the power combination row pipe connecting and installing structure provided by the application has the following beneficial effects: The structure of the application designs the row pipe frame as a modular structure, and the row pipe frame modules 1 are connected in a splicing manner to form row pipe frames 10 with different structures, which are suitable for different pipe arrangement requirements. Meanwhile, according to different combination modes, various connecting pieces are designed to adapt to the connection and structure reinforcement between the modules.

[0037] The above only describes some exemplary embodiments of the application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
