Description

Technical Field

[0001] The utility model relates to the field of pipeline engineering, in particular to a pipeline support and a conveying system. Background Art

[0002] In actual use of pipelines, due to temperature changes and other reasons, the pipelines may expand or contract or move. In order to firmly connect the pipelines with other components, pipeline supports are needed to limit the displacement of the pipelines.

[0003] Chinese utility model patent CN203686361U provides a pipe support with a support spring installed below the pipe. When the pipe moves vertically, the spring's expansion and contraction adjust the pipe's vertical height, preventing vertical displacement of the pipe's connection with other components. A polytetrafluoroethylene plate is installed horizontally to reduce horizontal displacement of the pipe. Although this reduction reduces horizontal displacement, the pipe remains horizontally movable. Horizontal displacement of the pipe at the connection with other components can result in an unstable connection, making this solution unsuitable for applications requiring horizontal stress limitation. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem in the prior art that the pipeline support causes the pipeline to be displaced in the horizontal direction, resulting in unstable connection between the pipeline and other components, and is not suitable for situations where horizontal stress needs to be limited.

[0005] In order to achieve the above object, the utility model provides a pipe support, which is arranged between the pipe and the embedded base and includes:

[0006] an inner tube, the top end of the inner tube being connected to the pipeline and extending vertically downward from the pipeline so as to be movable in the vertical direction along with the pipeline;

[0007] The outer tube is vertically arranged on the embedded base, and the upper end of the outer tube is sleeved outside the lower end of the inner tube;

[0008] a telescopic member disposed in a vertical gap between the inner tube and the outer tube and telescopically supported below the inner tube; and

[0009] The sliding support is arranged in the annular gap between the inner tube and the outer tube to define the radial relative positions of the inner tube and the outer tube and allow the inner tube to slide in the vertical direction relative to the outer tube.

[0010] In some embodiments, the telescopic component includes an elastic member and fixing members disposed at both ends of the elastic member and connected to the inner tube and the outer tube respectively.

[0011] In some embodiments, the elastic member is a vertically arranged coil spring, and the fixing member includes an upper pressure plate and a lower pressure plate. The upper pressure plate is arranged at the radial section of the inner tube, and the lower pressure plate is arranged at the radial section of the outer tube. The two ends of the coil spring are respectively abutted against the upper pressure plate and the lower pressure plate.

[0012] In some embodiments, the sliding support includes a rotating member and a supporting member for positioning the rotating member at a predetermined position on the outer tube, and the rotating member abuts against the outer wall surface of the inner tube.

[0013] In some embodiments, the rotating member is a plurality of balls, and the supporting member is an upper baffle and a lower baffle arranged above and below the balls around the inner wall of the outer tube. When the inner tube moves, the balls rotate in the area surrounded by the upper baffle and the lower baffle.

[0014] In some embodiments, two side baffles are vertically provided on the sides of the ball, and when the inner tube moves, the ball rotates in the area surrounded by the upper baffle, the lower baffle and the two side baffles.

[0015] In some embodiments, the rotating member is a plurality of rollers, which are horizontally arranged and can rotate around a horizontal axis. The supporting member is a plurality of rotating shafts and a plurality of support rods, which are arranged at both ends of the rollers and connected to the inner wall of the outer tube. The two ends of the rollers are rotatably connected to the support rods through the rotating shafts.

[0016] In some embodiments, the inner tube is a circular tube or a polygonal tube, and the outer tube is a circular tube or a polygonal tube.

[0017] In some embodiments, the top end of the outer tube has a flange extending radially inward.

[0018] Another aspect of the present invention provides a conveying system, which includes a pipeline supported by the above-mentioned pipeline support.

[0019] Through this technical solution, the inner tube moves synchronously with the pipeline. An outer tube is positioned outside the inner tube to restrict its horizontal movement. A telescopic component is provided to enable the inner tube to move vertically relative to the outer tube and provide support. A sliding support is provided between the outer and inner tubes, ensuring that the inner tube remains immobile horizontally while moving vertically along the outer tube. This allows the pipeline to move vertically but not horizontally. The pipeline does not deviate horizontally, providing a more secure connection to other components. This provides a pipeline support that restricts horizontal displacement while not restricting vertical displacement, increasing the flexibility of adjusting thermal stresses in the pipeline.

[0027] In this utility model, unless otherwise indicated, directional terms such as "upper," "lower," "left," "right," "inner," and "outer" are used to indicate directions or positional relationships for the sole purpose of facilitating the description of this utility model and simplifying the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0028] In the actual application of pipeline engineering, it is often encountered that the pipeline needs to have vertical displacement while limiting horizontal displacement. For example, an L-shaped pipe needs to be movable in the vertical direction to compensate for the height change of the pipe due to temperature changes and other reasons, but the movement of the pipe needs to be limited in the horizontal direction, otherwise the connection between the pipe and other components will be offset and the connection will be unstable. This problem can be solved by setting a pipe bracket. In order to solve the problem that the pipe bracket in the prior art causes the pipe to be displaced in the horizontal direction, resulting in an unstable connection between the pipe and other components, the utility model provides a pipe bracket, such as Figure 1 and Figure 2As shown, the pipe support is arranged between the pipe 1 and the embedded base 2, and includes: an inner pipe 3, the top end of the inner pipe 3 is connected to the pipe 1, and extends vertically downward from the pipe 1 so as to be able to move in the vertical direction with the pipe 1; an outer pipe 4, the outer pipe 4 is vertically arranged on the embedded base 2, and the upper end of the outer pipe 4 is sleeved outside the lower end of the inner pipe 3; a telescopic component 5, the telescopic component 5 is arranged in the vertical gap between the inner pipe 3 and the outer pipe 4, and is telescopically supported below the inner pipe 3; and: a sliding support 6, the sliding support 6 is arranged in the annular gap between the inner pipe 3 and the outer pipe 4 to limit the radial relative position of the inner pipe 3 and the outer pipe 4 and allow the inner pipe 3 to slide in the vertical direction relative to the outer pipe 4.

[0029] like Figure 1 and Figure 2 As shown, the top end of the inner tube 3 is connected to the pipeline 1. The top end of the inner tube 3 can be connected to the bottom of the pipeline 1 by welding or other means, and the inner tube 3 moves synchronously with the pipeline 1. The upper end of the outer tube 4 is sleeved outside the lower end of the inner tube 3. The horizontal movement of the inner tube 3 is blocked by the outer tube 4, limiting the horizontal movement of the inner tube 3. A telescopic component 5 is provided in the vertical gap between the inner tube 3 and the outer tube 4 to provide support for the inner tube 3 during vertical movement. A sliding support 6 is provided in the annular gap between the inner tube 3 and the outer tube 4 to allow the inner tube 3 to slide vertically relative to the outer tube 4 via the sliding support 6. Through the above technical solution, inner tube 3 moves synchronously with pipeline 1. Outer tube 4 is provided outside inner tube 3 to limit its horizontal movement. Telescopic component 5 is provided to enable inner tube 3 to move vertically relative to outer tube 4 and provide support for its movement. Sliding support 6 is provided between outer tube 4 and inner tube 3, so that inner tube 3 cannot move horizontally while moving vertically along outer tube 4. This makes pipeline 1 movable vertically but immobile horizontally. Pipe 1 does not deviate horizontally, and its connection with other components is more stable. This provides a pipeline support that limits horizontal displacement while not restricting vertical displacement, thereby improving the flexibility of pipeline thermal stress adjustment.

[0030] In some embodiments, as Figure 1 and Figure 2 As shown, the telescopic component 5 may include an elastic member and fixing members provided at both ends of the elastic member and respectively connected to the inner tube 3 and the outer tube 4. The fixing members connect the two ends of the elastic member to the inner tube 3 and the outer tube 4. When the inner tube 3 and the outer tube 4 undergo relative displacement in the vertical direction, the elastic member is stretched or compressed along with the inner tube 3 and plays a supporting role. Alternatively, the fixing members may not be provided, and the elastic member may be directly provided in a shape with wide ends and a narrow middle, and the two ends of the elastic member may be directly fixed to the inner tube 3 and the outer tube 4, such as by directly welding or screwing the top and bottom coils of the coil spring to the inner tube 3 and the outer tube 4, or by fixing the upper end of the elastic member to the pipe opening at the lower end of the inner tube 3 or the lower end of the pipeline 1, and fixing the lower end of the elastic member to the embedded base 2.

[0031] In some embodiments, as Figure 1 and Figure 2 As shown, the elastic member is a vertically mounted coil spring 53, and the fixed member includes an upper pressing plate 51 and a lower pressing plate 52. The upper pressing plate 51 is welded to the radial cross-section of the inner tube 3, while the lower pressing plate 52 is welded to the radial cross-section of the outer tube 4. The ends of the coil spring 53 abut the upper pressing plate 51 and the lower pressing plate 52, respectively. The upper pressing plate 51 and the lower pressing plate 52 can also be mounted at the radial cross-sections of the inner tube 3 and the outer tube 4 using other connection methods, such as riveting. The upper pressing plate 51 moves vertically with the inner tube 3, stretching or compressing the coil spring 53. The lower pressing plate 52 provides stable support for the deformation of the coil spring 53, thereby providing flexible support for the inner tube 3 in the vertical direction. The elastic member can also be a disc spring, with its ends connected to the upper pressing plate 51 and the lower pressing plate 52, respectively. Alternatively, multiple coil springs 53 can be provided, each connected to the upper pressing plate 51 and the lower pressing plate 52, respectively. In addition to the spring, the elastic member can also be an elastic block made of elastic material such as rubber, which fills the entire lower end of the inner tube 3 and extends downward to the lower pressing plate 52, or directly extends to the embedded base 2 without the lower pressing plate 52. The shape of the upper pressing plate 51 and the lower pressing plate 52 is not limited to a flat plate. The contact surfaces of the upper pressing plate 51 and the lower pressing plate 52 with the coil spring 53 can be provided with protrusions, and the uppermost and lowermost coils of the coil spring 53 are respectively mounted on the protrusions to fix the coil spring 53.

[0032] In some embodiments, as Figure 1 and Figure 2 As shown, the sliding support 6 includes a rotating member and a support member that positions the rotating member at a predetermined position on the outer tube 4. The rotating member abuts the outer wall surface of the inner tube 3. When the inner tube 3 moves in the vertical direction, the rotating member rotates and is slidably connected to the outer wall surface of the inner tube 3. Of course, the sliding support 6 can also be set on the inner tube 3, and the support member positions the rotating member at a predetermined position on the inner tube 3. The rotating member abuts the inner wall surface of the outer tube 4. When the inner tube 3 moves in the vertical direction, the rotating member rotates and is slidably connected to the inner wall surface of the outer tube 4.

[0033] In some embodiments, as Figure 3 and Figure 4 As shown, the rotating members are multiple balls 601, and the supporting members are upper and lower baffles 602 and 603, which are arranged above and below the balls 601 and surround the inner wall of the outer tube 4. When the inner tube 3 moves, the balls 601 rotate within the area enclosed by the upper and lower baffles 602 and 603. The side of the balls 601 closest to the inner tube 3 protrudes outside the upper and lower baffles 602 and 603, and is slidably connected to the outer wall of the inner tube 3. Figure 4The middle balls 601 are closely arranged in the area enclosed by the upper baffle 602 and the lower baffle 603 , which can also reduce the number of balls 601 , and the multiple balls 601 are loosely arranged. Figure 4 The inner tube 3 and outer tube 4 are both circular tubes. Alternatively, the inner tube 3 can be a polygonal tube and the outer tube 4 a circular tube; alternatively, the outer tube 4 can be a polygonal tube and the inner tube 3 a circular tube; alternatively, both the inner tube 3 and the outer tube 4 can be polygonal tubes, with the balls 601 tangential to the inner tube 3 and the outer tube 4, respectively, within the annular gap between the inner tube 3 and the outer tube 4. To stably guide the vertical movement of the inner tube 3 relative to the outer tube 4 and restrict their horizontal relative movement, in a preferred embodiment of the pipe support, multiple layers of balls 601, upper baffles 602, and lower baffles 603 can be provided at different heights or at different axial locations on the outer tube 4.

[0034] In some embodiments, as Figure 5 As shown, two side baffles 604 are vertically provided on the side of the ball 601, and the side of the ball 601 close to the inner tube 3 also protrudes from the side baffle 604. When the inner tube 3 moves, the ball 601 rotates in the area surrounded by the upper baffle 602, the lower baffle 603 and the two side baffles 604. Figure 5 The balls 601 are separated by side baffles 604 and do not contact each other. Therefore, upper and lower baffles 602 and 603 can be spaced apart along the inner wall of the outer tube 4, above and below each ball 601, respectively. Alternatively, the inner tube 3 can be configured as a polygonal prism and the outer tube 4 as a circular tube; or the outer tube 4 can be configured as a polygonal prism and the inner tube 3 as a circular tube; or both the inner tube 3 and the outer tube 4 can be polygonal prisms, with the balls 601 being tangential to the inner tube 3 and the outer tube 4, respectively, within the annular gap between them. To stably guide the vertical movement of the inner tube 3 relative to the outer tube 4 and restrict their horizontal relative motion, a preferred embodiment of the pipe support can include multiple layers of balls 601, upper baffles 602, lower baffles 603, and side baffles 604 at different heights or at different axial locations on the outer tube 4.

[0035] In some embodiments, the rotating member is a plurality of rollers, which are arranged horizontally and can rotate around a horizontal axis. The supporting member is a plurality of rotating shafts and a plurality of support rods, which are arranged at both ends of the rollers and connected to the inner wall of the outer tube 4. The two ends of the rollers are rotatably connected to the support rods via the rotating shafts. The side of the roller close to the inner tube 3 protrudes outside the support rod and is slidably connected to the inner tube 3. When the inner tube 3 moves in the vertical direction, the roller is rotatably connected to the support rod. The outer tube 4 is a polygonal tube, and each roller is correspondingly arranged on each side of the outer tube 4. The outer tube 4 can also be set as a circular tube, and multiple rollers are arranged around the inner wall of the outer tube 4, and fixed to the inner wall of the outer tube 4 via the rotating shafts and support rods. Similarly, the inner tube 3 can also be a polygonal tube, with the edges of the polygonal tube in point contact with the rollers and the sides of the polygonal tube in surface contact with the rollers. In order to stably guide the inner tube 3 to move relative to the outer tube 4 in the vertical direction and limit its relative movement in the horizontal direction, in a preferred embodiment of the pipe support, multiple layers of rollers, rotating shafts and support rods can be set at different height positions or different axial settings of the outer tube 4.

[0036] In some embodiments, the inner tube 3 is a circular tube or a polygonal tube, the outer tube 4 is a circular tube or a polygonal tube, or the inner tube 3 and the outer tube 4 are any combination of circular tubes or polygonal tubes.

[0037] In some embodiments, as Figure 1 and Figure 2 As shown, the top end of the outer tube 4 has a radially inwardly extending flange. This flange defines the direction of movement of the inner tube 3 during vertical movement, allowing the inner tube 3 to move up and down within the area enclosed by the flange. The flange defines the direction of movement of the inner tube 3, allowing the sliding support 6, which only needs one layer in the gap between the inner tube 3 and the outer tube 4, to ensure stable vertical movement of the inner tube 3, reducing production costs. Furthermore, when the sliding support 6 is positioned on the inner tube 3, the flange prevents the inner tube 3 from sliding out of the outer tube 4 during upward movement.

[0038] In some embodiments, the present invention further provides a conveying system, which comprises a pipeline 1 supported by the above-mentioned pipeline support.

[0039] While the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple variations and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.
