Description

Technical Field

[0001] The present application relates to the technical field of terminal plates, and in particular to an anti-deformation terminal plate structure. Background Art

[0002] In pipeline engineering, flanges are mainly used for connecting pipelines. Pipe pile end plates are divided into two types: flange plates and flange discs, which are used to install and fix pipe fittings. During installation and use, existing end plates often deform due to insufficient strength.

[0003] In this regard, China's patent application number CN202120085519.X discloses an anti-deformation end plate. This solution mainly saves materials by setting a hollow groove and two reinforcing rods. On the other hand, the tripod composed of two reinforcing rods can increase the stability of the end base plate and avoid deformation due to excessive pressure.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] The above solution mainly enhances the strength of the end plate itself, but in actual application, the connection between the pipeline and the end plate is more prone to deformation due to stress concentration, and the above solution does not make any improvement on this. Utility Model Content

[0006] In order to make up for the above deficiencies, the present application provides an anti-deformation end plate structure, aiming to improve the problems mentioned in the above background technology.

[0007] An embodiment of the present application provides an anti-deformation end plate structure, including a disk body, a sleeve vertically fixedly connected to the disk body, sliding pads distributed in an array on the inner wall of the sleeve, the sliding pads being slidably connected to the inclined surface of the inner wall of the sleeve, all of the sliding pads moving beyond the end face of the disk body, and all of the sliding pads clamping pipe fittings.

[0008] In a specific embodiment, reinforcing ribs are provided between the disc body and the sleeve.

[0009] In a specific embodiment, the connection between the reinforcing rib, the disc body and the sleeve is in an arc transition.

[0010] In the above implementation process, the reinforcing ribs are used to ensure a good connection between the disc body and the sleeve, improve the overall structural strength of the end plate, reduce its own deformation, and the arc transition is conducive to stress dispersion to avoid cracking at the connection.

[0011] In a specific embodiment, the cross-section of the reinforcing rib is triangular.

[0012] In the above implementation process, the triangular cross-section provides better stability, reduces the deformation of the end plate itself, and is also beneficial to reducing the weight of the structure. In this embodiment, the disc body, sleeve and reinforcement ribs are formed as one piece, which is beneficial to reducing costs and improving structural strength.

[0013] In a specific embodiment, a mounting hole is provided on the disc body.

[0014] In a specific embodiment, the location of the mounting hole is thickened.

[0015] In the above implementation process, the disk body itself is relatively thin. When fasteners such as bolts are used for installation, the stress will be concentrated near the fasteners. In order to improve the connection strength, the triangular area where the mounting hole is located is thickened, and a chamfer is added between the reinforcement ribs so as to evenly disperse and transfer the installation stress to the reinforcement ribs, which is beneficial to improve the overall strength.

[0016] In a specific embodiment, the inner wall of the sleeve is provided with a sliding groove adapted to each of the sliding pads, and the inner walls of all the sliding pads are tightened with elastic rings.

[0017] In the above implementation process, before the end plate is installed, it is necessary to keep all the sliding pads in their respective sliding grooves. In order to prevent the sliding pads from falling off during installation, elastic rings are used to tighten all the sliding pads from the inside to the outside. Grooves are provided on the sliding pads to form an annular groove to accommodate the elastic rings. In the present embodiment, two elastic rings are provided, respectively at the head and tail of the sliding pad. It should be noted that the sliding pad itself has a certain elasticity so that it can better fit the outer circle of the pipe fitting and increase the contact area.

[0018] In a specific embodiment, a gasket is movably fitted to the end surface of the disk.

[0019] In the above implementation process, after the end plate is installed and fixed to other planes, the end faces of all sliding pads are flush with the end faces of the disk body. At this time, the inner diameter surrounded by all sliding pads is fixed. In order to adapt to the diameter of the actual clamped pipe, an appropriate number of gaskets need to be set to adjust the axial position of all sliding pads on the sleeve, so as to adjust the inner diameter of the clamp.

[0020] Compared with the prior art, the beneficial effects of the present application are: the circular array on the inner wall of the sleeve is connected to the inclined surface of the inner wall of the sleeve through a sliding pad, and when the end plate is installed and used, the inner diameter of the sliding pad of the circular array is automatically reduced to wrap and fix the pipe fitting, thereby increasing the contact area with the disk body and the pipe fitting, improving the connection strength and reducing the deformation of the connection.

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1 The present application provides an anti-deformation end plate structure, including a disk body 1, a sleeve 2 is vertically fixedly connected to the disk body 1, and sliding pads 3 are distributed in an array on the inner wall of the sleeve 2. The sliding pads 3 are slidingly connected to the inclined surface of the inner wall of the sleeve 2, all the sliding pads 3 move beyond the end surface of the disk body 1, and all the sliding pads 3 are clamped with pipe fittings 4.

[0029] Among them, the circular array on the inner wall of the sleeve 2 is connected to the inclined surface of the inner wall of the sleeve 2 through a sliding pad 3 that is slidably connected. When the end plate is installed and used, the sliding pad 3 of the circular array automatically reduces the inner diameter to wrap and fix the pipe 4, thereby increasing the contact area with the disc body 1 and the pipe 4, improving the connection strength and reducing the deformation of the connection.

[0030] See also Figure 1 to Figure 2 A reinforcing rib 5 is provided between the disc body 1 and the sleeve 2. The connection between the reinforcing rib 5 and the disc body 1 and the sleeve 2 is in an arc transition. The reinforcing rib 5 is used for a good connection between the disc body 1 and the sleeve 2, improving the overall structural strength of the end plate and reducing its own deformation. The arc transition is conducive to the dispersion of stress and avoids cracking at the connection.

[0031] See also Figure 1 to Figure 2The cross section of the reinforcing rib 5 is triangular. The triangular cross section provides better stability, reduces the deformation of the end plate itself, and is also conducive to reducing the weight of the structure. In this embodiment, the disc body 1, the sleeve 2 and the reinforcing rib 5 are integrally formed, which is conducive to reducing costs and improving structural strength.

[0032] See also Figure 1 to Figure 2 , a mounting hole is provided on the disk body 1. The location of the mounting hole is thickened. The disk body 1 itself is relatively thin. When fasteners such as bolts are used for installation, stress will be concentrated near the fasteners. In order to improve the connection strength, the triangular area where the mounting hole is located is thickened, and a chamfer is added between the rib 5 so as to evenly disperse and transfer the installation stress to the rib 5, which is beneficial to improve the overall strength.

[0033] See also Figures 1 to 4 The inner wall of the sleeve 2 is provided with a slide groove adapted to each slide pad 3, and the inner walls of all slide pads 3 are tightened with an elastic ring 6. Before the end plate is installed, it is necessary to keep all the slide pads 3 in their respective slide grooves. In order to prevent the slide pads 3 from falling off during installation, the elastic ring 6 is tightened from the inside to the outside on all the slide pads 3. The slide pads 3 are provided with grooves to form an annular groove to accommodate the elastic ring 6. In this embodiment, two elastic rings 6 are provided, which are respectively arranged at the head and tail of the slide pad 3. It should be noted that the slide pad 3 itself has a certain elasticity so that it can better fit the outer circle of the pipe fitting 4 and increase the contact area.

[0034] See also Figures 1 to 4 , the end surface of the disc body 1 is movably fitted with a gasket 7. After the end plate is fixed to other planes, the end surfaces of all the sliding pads 3 are flush with the end surface of the disc body 1. At this time, the inner diameter surrounded by all the sliding pads 3 is fixed. In order to adapt to the diameter of the actual clamped pipe 4, an appropriate number of gaskets 7 need to be set to adjust the axial position of all the sliding pads 3 on the sleeve 2, so as to adjust the inner diameter of the clamp.

[0035] The working principle of the anti-deformation end plate structure is: put the sleeve 2 on the pipe fitting 4. If the pipe fitting 4 has its own lip or flange, all the sliding pads 3 are pressed against the lip of the pipe fitting 4. When connected with another flange structure, the lip of the pipe fitting 4 or all the sliding pads 3 are pressed against the end face of the other flange structure, and then the plate body 1 is locked with the other flange structure by fasteners such as bolts. In the process of the sleeve 2 gradually fitting with the end face of the other flange structure, all the sliding pads 3 will move axially. Since the sliding pads 3 slide on the inclined surface of the inner wall of the sleeve 2, the sliding pads 3 will also move radially, and all the sliding pads 3 will shrink inward to clamp the pipe fitting. 4. When the disc body 1 is completely fitted with the end face of another flange structure, the sliding pad 3 locks the pipe fitting 4 to achieve the effect of connecting and fixing the end plate and the pipe fitting 4. If necessary, the sleeve 2 and the pipe fitting 4 can be further fixed, such as by welding for a week, to achieve the effect of axial fixing. In summary, the sliding pad 3 of the circular array on the inner wall of the sleeve 2 is connected to the inclined surface of the inner wall of the sleeve 2 through the sliding pad 3. When the end plate is installed and used, the sliding pad 3 of the circular array automatically reduces the inner diameter to wrap and fix the pipe fitting 4, thereby increasing the contact area with the disc body 1 and the pipe fitting 4, improving the connection strength and reducing the deformation of the connection.
