Description

Technical Field

[0001] The utility model relates to the technical field of oil pipeline support and positioning, and particularly to a double pipe clamp with adjustable installation angle for preventing deformation of chemical pipelines. Background Art

[0002] At the oil extraction site, there are various pipelines such as water pipes, mud pipelines, crude oil pipelines, and hydraulic oil pipes. In order to limit the movement of the pipelines, pipe clamps are sometimes used to fix the relevant pipelines. When the pipelines are arranged densely, double pipe clamps are also used to separate two adjacent pipelines to avoid interference between adjacent pipelines.

[0003] For example, Chinese patent document CN209557802U provides a double pipe clamp, which has a first pipe clamp and a second pipe clamp, and the first pipe clamp and the second pipe clamp are rotatably connected, so that the angle between the first pipe clamp and the second pipe clamp can be conveniently adjusted, and thus it can be used in a wider range of scenarios.

[0004] However, in order to better fix the pipeline, ideally, it is hoped that after the pipeline passes through the pipe clamp, the direction of the pipe clamp is relatively fixed to limit the direction of the pipeline. In the above-mentioned double pipe clamp, the first pipe clamp and the second pipe clamp are rotatably connected, and the direction of the pipe clamp will change with the direction of the pipeline, making it difficult to play a role in restricting the direction of the pipeline. Summary of the Utility Model

[0005] The utility model provides a double pipe clamp with adjustable installation angle for preventing deformation of chemical pipelines, aiming to provide a double pipe clamp that can meet various installation angles and has a fixed angle after installation.

[0006] The utility model provides a double pipe clamp with adjustable installation angle for preventing deformation of chemical pipelines, including: a first pipe clamp, which is provided with a connecting sleeve, and the connecting sleeve is provided with a rotation-limiting hole, and the rotation-limiting hole is a regular polygon hole; a second pipe clamp, which is provided with a rotation-limiting column, and the rotation-limiting column is fixedly connected to the second pipe clamp, the connecting shaft can rotate relative to the second pipe clamp, the rotation-limiting column is inserted into the connecting sleeve, and the rotation-limiting column is provided with a limiting protrusion with a regular polygon cross-section, and the limiting protrusion corresponds to the rotation-limiting hole; and an elastic tension member, one end of which is connected to the first pipe clamp and the other end is connected to the second pipe clamp, and the elastic tension member is used to pull the first pipe clamp and the second pipe clamp closer, so that the limiting protrusion is located in the rotation-limiting hole, and when the second pipe clamp is manually pulled away from the first pipe clamp, the limiting protrusion can be disengaged from the rotation-limiting hole.

[0007] In one embodiment, the central axis of the rotation-limiting hole is perpendicular to and intersects the axis of the first pipe clamp, and the central axis of the limiting protrusion is perpendicular to and intersects the axis of the second pipe clamp.

[0008] In one embodiment, the connecting sleeve is further provided with a first mounting hole communicating with the rotation limiting hole. The first mounting hole is located on the side of the rotation limiting hole away from the second pipe clamp, and the diameter of the first mounting hole is smaller than that of the rotation limiting hole. A positioning stepped surface is formed at the connection between the first mounting hole and the rotation limiting hole. When the limiting protrusion abuts against the positioning stepped surface, the elastic tension member is in a stretched state.

[0009] In one embodiment, the elastic tension member is located in the first mounting hole.

[0010] In one embodiment, the rotation limiting post is provided with a through second mounting hole. The second pipe clamp includes a hoop structure and a connecting shaft. The connecting shaft is located in the second mounting hole and is rotatably connected to the hoop structure, and one end of the elastic tension member away from the first pipe clamp is connected to the connecting shaft.

[0011] In one embodiment, the elastic tension member includes a spring body and a hook portion. The spring body is connected to the hook portion. The connecting shaft is provided with a first through hole, and the hook portion passes through the first through hole and is hooked to the connecting shaft.

[0012] In one embodiment, the rotation limiting hole is a regular octagon hole.

[0013] In one embodiment, the first pipe clamp includes a first hoop body and a second hoop body. One end of the first hoop body is connected to the second hoop body, and the other end of the first hoop body and the second hoop body enclose a notch. The first pipe clamp further includes a locking assembly disposed at the notch. The locking assembly is used to lock or unlock the first hoop body and the second hoop body at the notch.

[0014] In one embodiment, the locking member assembly includes a locking nut and a locking screw. The locking nut is fixed to the first hoop body, and the locking screw passes through the second hoop body and is threadedly connected to the locking nut.

[0015] In one embodiment, a bushing is provided on the inner side of the first pipe clamp and / or the second pipe clamp.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: The first pipe clamp can be first connected to the first pipeline. When it is inconvenient for the second pipeline to pass through in the direction of the second pipe clamp, the second pipe clamp can be pulled away from the first pipe clamp, so that the rotation limiting protrusion of the rotation limiting post in the second pipe clamp moves out of the rotation limiting hole of the first pipe clamp, and the included angle between the second pipe clamp and the first pipe clamp can be conveniently adjusted to allow the second pipeline to pass through the second pipe clamp, which has a wider range of use compared with a double pipe clamp with a single included angle. Then, the second pipe clamp can be released, and under the elastic force of the elastic tension member, the second pipe clamp approaches the first pipe clamp, and the limiting protrusion is inserted into the rotation limiting hole. The cooperation between the limiting protrusion and the rotation limiting hole prevents the second pipe clamp from rotating relative to the first pipe clamp, thereby avoiding changing the included angle between the pipe clamps due to the shaking of the pipeline.

[0026] The present utility model will be further described below with reference to the accompanying drawings.

[0027] As Figures 1 to 3 shown, a double pipe clamp with adjustable installation angle for preventing deformation of chemical pipelines provided by the present application includes a first pipe clamp 1, a second pipe clamp 2, and an elastic tension member 3. Among them, the first pipe clamp 1 has a connecting sleeve 11, and the connecting sleeve 11 is provided with a regular polygon rotation limiting hole 111. The second pipe clamp 2 is provided with a rotation limiting column 21 having a limiting protrusion 211, and the second pipe clamp 2 is further provided with a connecting shaft 22.

[0028] One end of the elastic tension member 3 is connected to the first pipe clamp 1, and the other end of the elastic tension member 3 is connected to the second pipe clamp 2. The elastic tension member 3 is used to pull the first pipe clamp 1 and the second pipe clamp 2 closer, so that the limiting protrusion 211 is located in the rotation limiting hole 111. And when the second pipe clamp 2 is manually pulled away from the first pipe clamp 1, the limiting protrusion 211 can be disengaged from the limiting hole.

[0029] Since the rotation-limiting hole 111 is a regular polygon hole, and the rotation-limiting protrusion 211 has a regular polygon cross-section and corresponds to the rotation-limiting hole 111, when the rotation-limiting protrusion 211 is inserted into the rotation-limiting hole 111, the outer contour of the rotation-limiting protrusion 211 cooperates with the inner contour of the rotation-limiting hole 111, preventing the rotation-limiting protrusion 211 from rotating relative to the rotation-limiting hole 111. At the same time, since the rotation-limiting hole 111 is in the shape of a regular polygon rather than an irregular figure, when the rotation-limiting protrusion 211 is rotated by a specific angle relative to the axis of the rotation-limiting hole 111 (for example, for a regular n-sided polygon, rotate by X * a°, where a = 360 / n, and both X and n are positive integers), the rotation-limiting protrusion 211 can be inserted into the rotation-limiting hole 111. That is, the double pipe clamp provided in this application can provide fixation at multiple angles.

[0030] In addition, in this application, the first pipe clamp 1 and the second pipe clamp 2 are connected by an elastic tension member 3. In general scenarios, the elastic force of the elastic tension member 3 can keep the rotation-limiting post 211 of the second pipe clamp 2 in the connection sleeve 11 of the first pipe clamp 1. When the included angle needs to be adjusted, the second pipe clamp 2 can be pulled away from the first pipe clamp 1, so that the rotation-limiting protrusion 211 disengages from the rotation-limiting hole 111, which is very convenient for adjustment.

[0031] As Figure 1 shown, the central axis of the rotation-limiting hole 111 is perpendicular to and intersects with the axis of the first pipe clamp 1, and the central axis of the rotation-limiting protrusion is perpendicular to and intersects with the axis of the second pipe clamp 2. When the second pipe clamp 2 is rotated around the central axis of the rotation-limiting protrusion 211, the axis of the second pipe clamp 2 will deflect, resulting in a deflection angle relative to the axis of the first pipe clamp 1, achieving the angular deflection of the two pipe clamps.

[0032] In some implementation manners, the connection sleeve 11 is further provided with a first installation hole 112 communicating with the rotation-limiting hole 111. The first installation hole 112 is located on the side of the rotation-limiting hole 111 away from the second pipe clamp 2. The diameter of the first installation hole 112 is smaller than that of the rotation-limiting hole 111. A positioning step surface 113 is formed at the connection between the first installation hole 112 and the rotation-limiting hole 111. When the rotation-limiting protrusion 211 abuts against the positioning step surface 113, the elastic tension member 3 is in a stretched state. That is to say, the axial position of the rotation-limiting protrusion 211 is restricted by the positioning step surface 113, so that the rotation-limiting protrusion 211 is kept in the limiting hole and does not fall into the first installation hole 112. When the rotation-limiting protrusion 211 abuts against the positioning step surface 113, the distance between the first pipe clamp 1 and the second pipe clamp 2 is the smallest, that is, the elastic tension member 3 is already in the shortest state. At this time, the elastic tension member 3 is still in a stretched state, still having a tendency to contract, and still providing a tension force to keep the rotation-limiting protrusion 211 on the positioning step surface 113.

[0033] As Figure 3 and Figure 4As shown, the elastic tension member 3 is located in the first mounting hole 112. Compared with setting the elastic tension member 3 outside the connecting sleeve 11, the friction between the elastic tension member 3 and the external sand and gravel is reduced, and damage is avoided, which can better protect the elastic tension member 3. It can be understood that in other implementation manners, the elastic tension member 3 can also be set outside the connecting sleeve 11 and arranged side by side with the connecting sleeve 11. This allows for the installation of a larger-sized elastic tension member 3 and enables more convenient replacement.

[0034] As Figure 3 and Figure 4 shown, in some implementation manners, the rotation-limiting column 21 is provided with a through second mounting hole 212. The second pipe clamp 2 includes a hoop structure 23 and a connecting shaft 22. The connecting shaft 22 is located in the second mounting hole 212 and is rotatably connected to the hoop structure 23, and one end of the elastic tension member 3 far from the first pipe clamp 1 is connected to the connecting shaft 22. Among them, the hoop structure 23 is used to hoop outside the pipeline to fix the pipeline. When the second pipe clamp 2 rotates relative to the first pipe clamp 1, the positional angular relationship between the connecting shaft 22 and the first pipe clamp 1 does not change, and only the rotation occurs between the hoop structure 23 and the connecting shaft 22, avoiding the twisting of the elastic tension member 3 due to angle adjustment. This can better protect the elastic tension member 3.

[0035] In some implementation manners, the elastic tension member 3 includes a spring body 31 and a hook portion 32. The spring body 31 is connected to the hook portion 32. The connecting shaft 22 is provided with a first through hole 221, and the hook portion 32 passes through the first through hole 221 and is hooked to the connecting shaft 22. That is to say, the elastic tension member 3 is hooked and connected to the connecting shaft 22, avoiding the detachment of the elastic connecting member from the connecting shaft 22.

[0036] Among them, the elastic tension member 3 can adopt a spring, can also adopt an elastic rubber band, or other structures that can be elastically tensioned.

[0037] As Figure 4 shown, in some implementation manners, the rotation-limiting hole 111 is a regular octagon hole, and the included angle between the two pipe clamps can be adjusted to (0°, 45°, 90°, 135°, 180°, 225°, 270°). That is, there are seven included angle states, which can meet most angle requirements. Of course, the corresponding limit protrusion 211 needs to be set as a matching regular octagon. It can be understood that the shape of the rotation-limiting hole 111 is not limited to a regular octagon hole, and can also adopt regular polygon holes such as an equilateral triangle hole, a square hole, a regular pentagon hole, etc.

[0038] As Figure 1 and Figure 2As shown, the first pipe clamp 1 includes a first hoop body 12 and a second hoop body 13. One end of the first hoop body 12 is connected to the second hoop body 13, and the other end of the first hoop body 12 and the second hoop body 13 enclose a notch. The first pipe clamp 1 further includes a locking assembly 14 disposed at the notch. The locking assembly 14 is used to lock or unlock the first hoop body 12 and the second hoop body 13 at the notch. By locking the first hoop body 12 and the second hoop body 13 with the locking assembly 14, the pipe extending between the first hoop body 12 and the second hoop body 13 can be tightly held. By unlocking the first hoop body 12 and the second hoop body 13 with the locking assembly 14, the first hoop body 12 and the second hoop body 13 can be opened at the notch, facilitating the pipe to enter or exit the clamping space enclosed by the first hoop body 12 and the second hoop body 13.

[0039] In some implementation manners, the locking assembly 14 includes a locking nut 141 and a locking screw 142. The locking nut 141 is fixed to the first hoop body 12, and the locking screw 142 passes through the second hoop body 13 and is threadedly connected to the locking nut 141. It realizes the locking of the first hoop body 12 and the second hoop body 13 through threaded connection, and its locking effect is higher than that of the plug-in structure, and the pipe body can be firmly fixed in the first pipe clamp 1.

[0040] Preferably, in some implementation manners, a bushing 15 is provided on the inner side of the first pipe clamp 1 and / or the second pipe clamp 2. That is to say, the bushing 15 can be provided on the inner side of either the first pipe clamp 1 or the second pipe clamp 2, or the bushing 15 can be provided on the inner sides of both the first pipe clamp 1 and the second pipe clamp 2. By providing the bushing 15, the outer wall of the pipe can be better protected.

[0041] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and the components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
