Abstract
Description
Technical Field
[0001] The utility model belongs to the field of pipeline installation, in particular to a large-diameter vertical plastic pipe fixing structure outside a container. Background Art
[0002] The inlet riser or outlet riser of corrosion-resistant equipment is generally a large-diameter plastic pipe. When the flow direction or flow rate of the medium in the large-diameter vertical plastic pipe changes, a huge axial thrust or radial thrust will be generated, so the large-diameter vertical plastic pipe needs to be fixed and limited. At present, a pipe support frame is usually used to achieve the limiting effect. The pipe support frame is a frame-shaped bracket welded by channel steel to surround the large-diameter plastic vertical pipe, and the bracket is fixed to the outer wall of the corrosion-resistant container. Before the large-diameter plastic vertical pipe leaves the factory, a support block made of the same material as the large-diameter plastic vertical pipe is pre-installed at the bracket support. The support block is usually directly bonded to the outer wall of the large-diameter plastic vertical pipe. Since the support block is located on the bracket welded by the channel steel, the relative movement of the support block on the bracket plays a role in eliminating the axial or radial thrust. The frame is wrapped with rubber sheets to protect the plastic pipe. However, this type of large-diameter vertical plastic pipe fixing structure has the following disadvantages:
[0003] First, the support block is directly bonded to the plastic pipe, which has a low safety factor and there is a risk of the support block falling;
[0004] Second, the protective material wrapped around the frame is easy to fall off after long-term use, causing the plastic pipe to directly contact the frame, and in serious cases, the plastic pipe will be damaged. Utility Model Content
[0005] The utility model aims to provide a large-caliber vertical plastic pipe fixing structure outside a container to improve safety and reliability.
[0006] The technical scheme adopted by the utility model is: a large-diameter plastic vertical pipe fixing structure outside a container, comprising a frame-shaped bracket which surrounds the outer periphery of the large-diameter plastic vertical pipe and is fixed to the outer wall of the container, and a fixing support arranged on the large-diameter plastic vertical pipe; the fixing support comprises two semicircular arc-shaped arc-shaped guard plates with equal diameters and curvatures, ear plates are respectively fixed to the outer walls of both ends of each arc-shaped guard plate around its circumferential direction, the openings of the two arc-shaped guard plates are opposite to each other, and the ear plates of the two arc-shaped guard plates are connected by bolts to form an annular casing; a plurality of support plates are evenly arranged along the outer wall of the casing, the support plates are horizontally arranged and the inner ends thereof are fixed to the outer wall of the arc-shaped guard plates; the support plates are freely supported on the bracket.
[0007] Furthermore, the casing is divided into an upper section located above the support plate and a lower section located below the support plate along the vertical direction through the support plate, and the lower section is inserted into the frame of the bracket.
[0008] Furthermore, a side support leg is provided between the outer wall of the arc-shaped guard plate and each support plate. The side support leg is located above the support plate, and the inner end thereof is fixed to the outer wall of the arc-shaped guard plate, and the bottom end thereof is fixed to the top surface of the support plate.
[0009] Furthermore, along the radial direction of the casing, the outer end of the support plate extends to the outer end of the side support leg.
[0010] Furthermore, each arc-shaped guard plate has two side supporting legs; and after the two arc-shaped guard plates form a ring, the angle between two adjacent side supporting legs is a right angle.
[0011] Furthermore, a rubber pad is provided between the inner wall of the casing and the outer wall of the large-diameter plastic vertical pipe.
[0012] Furthermore, the top end of the rubber pad vertically exceeds the top end of the casing; the bottom end of the rubber pad vertically exceeds the bottom end of the casing.
[0013] The beneficial effects of the utility model are as follows: the utility model frames the large-diameter plastic vertical pipe through the bracket, and two arc-shaped guard plates form a casing that wraps around the outer periphery of the large-diameter plastic vertical pipe. The curvature of the casing is slightly smaller than the diameter of the large-diameter plastic vertical pipe, ensuring that the casing tightly holds the large-diameter plastic vertical pipe when the connecting bolts are tightened. The support plate fixed on the outer wall is freely supported on the bracket and can slide on the bracket, thereby supporting and limiting the large-diameter plastic vertical pipe, thereby ensuring the safe and stable operation of the large-diameter plastic vertical pipe.
[0014] Compared with the traditional method of bonding support blocks on large-diameter plastic vertical pipes, firstly, two arc-shaped protective plates are directly wrapped around the large-diameter plastic vertical pipes, and the connecting bolts are tightened. There is no need to bond the support blocks to the outer wall of the large-diameter plastic vertical pipes one by one, which is convenient for installation. Secondly, it can be installed on site. The traditional support blocks are bonded to the large-diameter plastic vertical pipes before leaving the factory, and there is a risk of falling during transportation. However, the casing disclosed in the utility model is detachably connected to the large-diameter plastic vertical pipe, and both factory assembly and on-site assembly are possible. Thirdly, several support plates are fixed on the outer wall of the casing to form a whole. The contact area between the casing and the large-diameter plastic vertical pipe is larger, the risk of the fixed support falling is greatly reduced, and the safety and connection stability reliability are higher. Furthermore, even if the casing moves under the action of axial force or radial thrust, it is still covered on the outer wall of the large-diameter plastic vertical pipe. The casing is vertically affected by gravity and the support of the bottom bracket, and it is not easy for the casing to fall off the large-diameter plastic vertical pipe. The large-diameter plastic vertical pipe fixed structure formed by the cooperation of the casing and the large-diameter plastic vertical pipe has higher strength and torque resistance.

[0019] In the figure, there are a large-diameter plastic vertical pipe 1, a container 2, a bracket 3, an arc-shaped guard plate 4, an ear plate 5, a connecting bolt 6, a support plate 7, a side leg 8, a rubber pad 9, a casing 10, an upper segment 10A, and a lower segment 10B. DETAILED DESCRIPTION
[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments:
[0021] In the present invention, the terms "lateral", "vertical", "longitudinal", "above", "below", "top", "top", "bottom", "bottom", "inner end" and "outer end" indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0022] Large diameter plastic vertical pipe fixing structure outside the container, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a frame-shaped bracket 3 that surrounds the outer periphery of the large-diameter plastic vertical pipe 1 and is fixed to the outer wall of the container 2, and a fixed support arranged on the large-diameter plastic vertical pipe 1; the fixed support includes two semicircular arc-shaped arc-shaped guard plates 4 with equal diameter and curvature, and ear plates 5 are respectively fixed to the outer walls of the two ends of each arc-shaped guard plate 4 around its circumferential direction, and the openings of the two arc-shaped guard plates 4 are opposite to each other and the ear plates 5 of the two arc-shaped guard plates 4 are connected together by connecting bolts 6 to form a ring-shaped casing 10; on the outer wall of the casing 10, several support plates 7 are evenly arranged along its outer wall, and the support plates 7 are arranged horizontally and their inner ends are fixed to the outer wall of the arc-shaped guard plate 4. The support plates 7 are freely supported on the bracket 3, that is, the support plates 7 and the bracket 3 are not connected, so as to ensure that the entire structure is less affected by axial or radial thrust.
[0023] The utility model frames a large-diameter plastic vertical pipe 1 through a bracket 3, and two arc-shaped guard plates 4 form a casing 10 that wraps around the outer periphery of the large-diameter plastic vertical pipe 1. The curvature of the casing 10 is slightly smaller than the diameter of the large-diameter plastic vertical pipe 1, ensuring that the casing 10 holds the large-diameter plastic vertical pipe 1 tightly when the connecting bolts 6 are tightened. The support plate 7 fixed on the outer wall is freely supported on the bracket 3 and can slide on the bracket 3, playing a supporting and limiting role for the large-diameter plastic vertical pipe 1, reducing the huge axial or radial thrust generated by changes in the flow direction or flow rate of the medium in the large-diameter vertical plastic pipeline, and ensuring the support strength and high torque resistance.
[0024] Compared with the traditional method of bonding support blocks on the large-diameter plastic vertical pipe 1, firstly, it is easy to install: just wrap the large-diameter plastic vertical pipe 1 with two arc-shaped protective plates 4 and tighten the connecting bolts 6, without bonding the support blocks to the outer wall of the large-diameter plastic vertical pipe 1 piece by piece. Secondly, it can be installed on site. Traditional support blocks are bonded to the large-diameter plastic vertical pipe 1 before leaving the factory, and there is a risk of falling during transportation. However, the casing 10 disclosed in the utility model is detachably connected to the large-diameter plastic vertical pipe 1, and both factory assembly and on-site assembly are possible. Thirdly, several support plates 7 are fixed to the outer wall of the casing 10 to form a whole. The contact area between the casing 10 and the large-diameter plastic vertical pipe 1 is larger, the risk of the fixed support falling is greatly reduced, and the safety and connection stability reliability are higher. Furthermore, even if the casing 10 moves under the action of axial force or radial thrust, it still covers the outer wall of the large-diameter plastic vertical pipe 1 and is not easy to separate from the large-diameter plastic vertical pipe 1 due to the vertical action of gravity and the support of the bottom bracket 3.
[0025] The bottom surface of the support plate 7 can be flush with the bottom surface of the casing 10. Preferably, the casing 10 is vertically divided into an upper segment 10A located above the support plate 7 and a lower segment 10B located below the support plate 7 through the support plate 7, and the lower segment 10B is inserted into the frame of the bracket 3. The lower segment 10B is inserted into the frame of the bracket 3, and when the large-diameter plastic vertical pipe 1 oscillates and moves, contact occurs between the lower segment 10B of the casing 10 and the bracket 3, avoiding the bracket 3 from directly contacting the large-diameter plastic vertical pipe 1, thereby protecting the large-diameter plastic vertical pipe 1.
[0026] In order to strengthen the support plate 7, preferably, a side leg 8 is provided between the outer wall of the arc-shaped guard plate 4 and each support plate 7, the side leg 8 is located above the support plate 7, and the inner end thereof is fixed to the outer wall of the arc-shaped guard plate 4, and the bottom end is fixed to the top surface of the support plate 7. The side leg 8 is in the shape of a right-angled trapezoid.
[0027] Preferably, along the radial direction of the casing 10, the outer end of the support plate 7 extends to the outer end of the side leg 8. The length of the support plate 7 is slightly longer than the bottom of the side leg 8, ensuring a larger contact area between the support plate 7 and the bracket 3, and reducing concentrated stress.
[0028] There are two side legs 8 on each arc-shaped guard plate 4; and after the two arc-shaped guard plates 4 are formed into a ring, the angle between two adjacent side legs 8 is a right angle.
[0029] Preferably, a rubber pad 9 is provided between the inner wall of the casing 10 and the outer wall of the large-diameter plastic vertical pipe 1 .
[0030] The rubber pad 9 plays a protective role between the casing 10 and the large-diameter plastic vertical pipe 1, and increases the friction between the casing 10 and the large-diameter plastic vertical pipe 1. The design thickness of the rubber pad needs to meet the requirements, and the rubber pad 9 is required to be made of a material with good elasticity and wear resistance.
[0031] In order to further protect the large-diameter vertical plastic pipe 1 , the top end of the rubber pad 9 vertically extends beyond the top end of the casing 10 ; the bottom end of the rubber pad 9 vertically extends beyond the bottom end of the casing 10 .
