Description

Technical Field

[0001] The invention relates to the field of pipeline engineering, and 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 required to limit the displacement of the pipelines.

[0003] Chinese utility model patent CN203686361U provides a pipe support, in which a support spring is arranged under the pipe. When the pipe is displaced in the vertical direction, the height of the pipe in the vertical direction is adjusted by the expansion and contraction of the spring, so that the connection between the pipe and other components in the vertical direction does not deviate. A polytetrafluoroethylene plate is arranged in the horizontal direction to reduce the horizontal deviation of the pipe. Although the horizontal deviation is reduced, the pipe can still be moved in the horizontal direction. The pipe deviates in the horizontal direction at the connection port with other components, and the connection is unstable. It is not applicable to the situation where horizontal stress needs to be limited. Summary of the invention

[0004] The purpose of the present invention 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 an 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 present invention provides a pipeline support, which is arranged between the pipeline and the embedded base and includes: An inner tube, the top end of which is connected to the pipeline and extends vertically downward from the pipeline so as to be able to move in the vertical direction along with the pipeline; An outer tube, 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; a telescopic member, which is disposed in a vertical gap between the inner tube and the outer tube and is telescopically supported below the inner tube; and: The sliding support is arranged in the annular gap between the inner tube and the outer tube to define the radial relative position of the inner tube and the outer tube and allow the inner tube to slide relative to the outer tube in the vertical direction.

[0006] In some embodiments, the telescopic component includes an elastic member and fixing members disposed at both ends of the elastic member and respectively connected to the inner tube and the outer tube.

[0007] 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. Both ends of the coil spring are respectively abutted against the upper pressure plate and the lower pressure plate.

[0008] 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.

[0009] 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.

[0010] In some embodiments, two side baffles are vertically arranged on the side 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.

[0011] In some embodiments, the rotating member is a plurality of rollers, the rollers are horizontally arranged and can rotate around a horizontal axis, the supporting member is a plurality of rotating shafts and a plurality of supporting rods, the supporting rods are arranged at both ends of the rollers and connected to the inner wall of the outer tube, and the two ends of the rollers are rotatably connected to the supporting rods through the rotating shafts.

[0012] 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.

[0013] In some embodiments, the top end of the outer tube has a flange extending radially inwardly.

[0014] Another aspect of the present invention provides a conveying system, which comprises a pipeline supported by the above-mentioned pipeline support.

[0015] Through the above technical solution, the inner tube moves synchronously with the pipeline, an outer tube is set outside the inner tube to limit the movement of the inner tube in the horizontal direction, a telescopic component is set to make the inner tube movable relative to the outer tube in the vertical direction and provide support, and a sliding support is set between the outer tube and the inner tube so that the inner tube cannot move in the horizontal direction on the basis of moving along the outer tube in the vertical direction, thereby making the pipeline movable in the vertical direction but immovable in the horizontal direction. The pipeline does not deviate in the horizontal direction, and the connection with other components is more stable, providing a pipeline support that does not limit vertical displacement while limiting horizontal displacement, and improving the flexibility of pipeline thermal stress adjustment.

[0018] In the present invention, unless otherwise stated, the directions or positional relationships indicated by the directional words such as "upper", "lower", "left", "right", "inner", "outer", etc. are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0019] 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 pipeline due to thermal expansion and contraction caused by temperature changes and other reasons, but the movement of the pipeline needs to be limited in the horizontal direction, otherwise the connection between the pipeline and other components will be offset and the connection will be unstable. This problem can be solved by setting a pipeline support. In order to solve the problem that the pipeline support in the prior art causes the pipeline to shift in the horizontal direction, resulting in an unstable connection between the pipeline and other components, and is not suitable for situations where horizontal stress needs to be limited, the present invention provides a pipeline support, 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.

[0020] like Figure 1 and Figure 2 As shown, the top end of the inner tube 3 is connected to the pipeline 1, and the top end of the inner tube 3 can be connected to the bottom of the pipeline 1 by welding or the like, 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, and the movement of the inner tube 3 in the horizontal direction is blocked by the outer tube 4, which limits the movement of the inner tube 3 in the horizontal direction. 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 when it moves in the vertical direction. 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 in the vertical direction relative to the outer tube 4 through the sliding support 6. Through the above technical solution, the inner tube 3 moves synchronously with the pipeline 1, the outer tube 4 is arranged outside the inner tube 3 to limit the movement of the inner tube 3 in the horizontal direction, the telescopic component 5 is arranged to make the inner tube 3 movable relative to the outer tube 4 in the vertical direction and provide support for the movement of the inner tube 3, and the sliding support 6 is arranged between the outer tube 4 and the inner tube 3, so that the inner tube 3 cannot move in the horizontal direction on the basis of moving along the outer tube 4 in the vertical direction, so that the pipeline 1 can move in the vertical direction but cannot move in the horizontal direction. The pipeline 1 does not deviate in the horizontal direction, and the connection with other components is more stable, providing a pipeline support that does not limit the vertical displacement while limiting the horizontal displacement, and improving the flexibility of the pipeline thermal stress adjustment.

[0021] In some embodiments, Figure 1 and Figure 2 As shown, the telescopic component 5 may include an elastic member and fixing members disposed at both ends of the elastic member and connected to the inner tube 3 and the outer tube 4, respectively. 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 are relatively displaced in the vertical direction, the elastic member is stretched or compressed along with the inner tube 3 and plays a supporting role. It is also possible not to set a fixing member, and directly set the elastic member to a shape with wide ends and thin middle, and directly fix the two ends of the elastic member to the inner tube 3 and the outer tube 4, such as directly welding the top and bottom circles of the coil spring to the inner tube 3 and the outer tube 4 with screws, or fixing the upper end of the elastic member to the pipe mouth 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.

[0022] In some embodiments, Figure 1 and Figure 2 As shown, the elastic member is a vertically arranged coil spring 53, and the fixing member includes an upper pressing plate 51 and a lower pressing plate 52. The upper pressing plate 51 is arranged at the radial section of the inner tube 3 by welding, and the lower pressing plate 52 is arranged at the radial section of the outer tube 4 by welding. The two ends of the coil spring 53 are respectively abutted against the upper pressing plate 51 and the lower pressing plate 52. The upper pressing plate 51 and the lower pressing plate 52 can also be arranged at the radial sections of the inner tube 3 and the outer tube 4 by other connection methods such as riveting. The upper pressing plate 51 moves in the vertical direction with the inner tube 3, stretching or compressing the coil spring 53, and the lower pressing plate 52 provides a stable support for the deformation of the coil spring 53, thereby providing a retractable support force for the inner tube 3 in the vertical direction. The elastic member can also be a disc spring, and the two ends of the disc spring are respectively connected to the upper pressing plate 51 and the lower pressing plate 52. The coil spring 53 can also be set to multiple, and the two ends are respectively connected to the upper pressing plate 51 and the lower pressing plate 52. In addition to the spring, the elastic member can also be an elastic block with 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. A protrusion can be set on the contact surface of the upper pressing plate 51 and the lower pressing plate 52 with the coil spring 53, and the uppermost and lowermost coils of the coil spring 53 are respectively sleeved on the protrusions to fix the coil spring 53.

[0023] In some embodiments, 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 against the outer wall surface of the inner tube 3, and when the inner tube 3 moves in the vertical direction, the rotating member rotates and is slidably connected with the outer wall surface of the inner tube 3. Of course, the sliding support 6 can also be set on the inner tube 3, the support member positions the rotating member at a predetermined position on the inner tube 3, the rotating member abuts against the inner wall surface of the outer tube 4, and when the inner tube 3 moves in the vertical direction, the rotating member rotates and is slidably connected with the inner wall surface of the outer tube 4.

[0024] In some embodiments, Figure 3 and Figure 4 As shown, the rotating member is a plurality of balls 601, and the supporting member is an upper baffle 602 and a lower baffle 603 arranged above and below the balls 601 and around the inner wall of the outer tube 4. When the inner tube 3 moves, the balls 601 rotate in the area surrounded by the upper baffle 602 and the lower baffle 603. The side of the balls 601 close to the inner tube 3 protrudes outside the upper baffle 602 and the lower baffle 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 plate 602 and the lower baffle plate 603 , and the number of the balls 601 can also be reduced, and the multiple balls 601 are loosely arranged. Figure 4 The inner tube 3 and the outer tube 4 are both circular tubes, and the inner tube 3 can also be set as a polygonal tube and the outer tube 4 can be set as a circular tube; or the outer tube 4 can be set as a polygonal tube and the inner tube 3 can be set as a circular tube; or the inner tube 3 and the outer tube 4 can both be polygonal tubes, and the ball 601 is tangent to the inner tube 3 and the outer tube 4 in the annular gap between the inner tube 3 and the outer tube 4. 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 pipeline support, multiple layers of ball 601, upper baffle 602 and lower baffle 603 can also be set at different height positions or different axial positions of the outer tube 4.

[0025] In some embodiments, Figure 5 As shown, two side baffles 604 are vertically arranged 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, the upper baffles 602 and the lower baffles 603 can be arranged along the inner wall of the outer tube 4, respectively above and below each ball 601. The inner tube 3 can also be set as a polygonal tube and the outer tube 4 can be set as a circular tube; or the outer tube 4 can be set as a polygonal tube and the inner tube 3 can be set as a circular tube; or the inner tube 3 and the outer tube 4 can be both polygonal tubes, and the balls 601 are tangent to the inner tube 3 and the outer tube 4 in the annular gap between the inner tube 3 and the outer tube 4. 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 pipeline support, multiple layers of balls 601, upper baffles 602, lower baffles 603 and side baffles 604 can also be arranged at different height positions or at different axial positions of the outer tube 4.

[0026] In some embodiments, Figure 6 As shown, the rotating member is a plurality of rollers 611, which are arranged horizontally and can rotate around a horizontal axis, and the supporting member is a plurality of rotating shafts 612 and a plurality of supporting rods 613, which are arranged at both ends of the rollers 611 and connected to the inner wall of the outer tube 4, and the two ends of the rollers 611 are rotatably connected to the supporting rods 613 through the rotating shafts 612. The side of the rollers 611 close to the inner tube 3 protrudes outside the supporting rods 613 and is slidably connected to the inner tube 3, and when the inner tube 3 moves in the vertical direction, the rollers 611 are rotatably connected to the supporting rods 613. Figure 6The outer tube 4 is a polygonal tube, and each roller 611 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 611 are arranged around the inner wall of the outer tube 4, and fixed to the inner wall of the outer tube 4 through the rotating shaft 612 and the support rod 613. Similarly, the inner tube 3 can also be a polygonal tube, and the edges of the polygonal tube are in point contact with the roller 611, and the sides of the polygonal tube are in surface contact with the roller 611. 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 pipeline support, multiple layers of rollers 611, rotating shafts 612 and support rods 613 can also be arranged at different height positions or at different axial positions of the outer tube 4.

[0027] 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, and the inner tube 3 and the outer tube 4 are any combination of circular tubes or polygonal tubes.

[0028] In some embodiments, Figure 1 and Figure 2 As shown, the top end of the outer tube 4 has a flange that protrudes radially inward to limit the moving direction of the inner tube 3 when the inner tube 3 moves in the vertical direction, so that the inner tube 3 moves up and down in the area surrounded by the flange. The arrangement of the flange limits the moving direction of the inner tube 3, so that the inner tube 3 can move up and down stably by only setting one layer of the sliding support 6 in the gap between the inner tube 3 and the outer tube 4, thereby reducing the production cost. In addition, when the sliding support 6 is arranged on the inner tube 3, when the inner tube 3 moves upward, the flange plays a role in preventing the inner tube 3 from sliding out of the outer tube 4.

[0029] In some embodiments, the present invention further provides a conveying system, which comprises a pipeline 1 supported by the above-mentioned pipeline support.

[0030] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
