Description

Technical Field

[0001] The utility model relates to the technical field of pipeline supports, in particular to a pipeline positioning variable diameter support structure. Background Art

[0002] The pipe support structure is an important component of the pipeline system. In addition to supporting the weight of the pipeline, the specially made pipe support can balance the force of the pipeline system, limit the displacement of the pipeline and absorb vibration. In the pipeline system, the use of appropriate and reasonable pipe supports can improve the stress distribution of the pipeline and the force on the pipe support, ensure the safe operation of the pipeline system, and extend its service life.

[0003] Currently in power plants, replacing the piping system often means that all pipe supports need to be removed and reinstalled, which requires a lot of manpower and financial resources. And in the special industry of power plants, ordinary pipe supports cannot withstand long-term high temperatures (200℃-500℃), which accelerates the damage of the entire equipment. In addition, variable diameter pipes are often used in power plants (that is, the two ends of the pipe are of different thicknesses; or the cross-section of the pipe, the lower and upper diameters are different, and the cross-section is not circular). This requires the use of pipe supports of different specifications, which is not convenient for centralized procurement. Therefore, the present application provides a power plant pipe support to solve the problems raised in the above background technology. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0025] See also Figure 1-Figure 3 .

[0026] The utility model discloses a pipeline positioning variable diameter support structure, comprising at least one pipeline support 01, the pipeline support 01 comprises an upper support seat 1, and a lower support seat 2 correspondingly connected and matched with the upper support seat 1, the upper support seat 1 and the lower support seat 2 are both provided with a semi-arc notch on one side of the opposite side, the semi-arc notches on the upper support seat 1 and the lower support seat 2 can be combined to form a through hole 3 for the pipeline to pass through, and the size of the through hole 3 is larger than the corresponding pipeline, so that the pipeline located in the through hole 3 and the through hole 3 have an air space between them, which is used for heat dissipation of the pipeline and reducing the temperature transmitted from the pipeline to the upper support seat 1 and the lower support seat 2;

[0027] A group of reducing blocks are arranged in the perforation 3, and the reducing blocks include at least two blocks 4. A first screw 41 is arranged at one end of each block 4 away from the pipe. Each block 4 is threadedly connected with the corresponding upper support seat 1 and lower support seat 2 through the first screw 41. Rotating the first screw 41 can adjust the corresponding block 4 to move closer to or away from the center direction of the perforation 3; one end of the block 4 corresponding to the pipe is arc-shaped, which is used to contact the pipe wall of the pipe and form a clamping support for the pipe.

[0028] In the specific implementation, first according to the corresponding pipe diameter, shape, and then rotate the first screw 41 to adjust the position of each block 4 in the through hole 3; after the adjustment, fix the lower support seat 2 (the lower support seat 2 is provided with a fixing hole for fixing) on ​​the wall / support to be installed (the pipe can be arranged horizontally above the room, or it can be arranged vertically along the wall), and then place the pipe in the semi-arc notch on the lower support seat 2, and then install the upper support seat 1, and fix the upper support seat 1 and the lower support seat 2 together, so that the relative position of the upper support seat 1 and the lower support seat 2 remains unchanged. Change; at this time, the semi-arc notches on the upper support seat 1 and the lower support seat 2 are combined to form a through hole 3 for the pipeline to pass through. The reducing block located in the through hole 3 clamps the pipeline so that the pipeline is located at the center of the through hole 3. While supporting the pipeline, an air space is maintained between the pipeline and the through hole 3, thereby reducing the temperature transmitted from the pipeline to the pipeline support 01 and extending the service life of the pipeline support 01; at the same time, the first screw 41 is threadedly connected to the corresponding support seat, so that the position of each block 4 in the through hole 3 can be adjusted independently, and can be used in different reducing pipelines.

[0029] The setting of the variable diameter block in the present application is, on the one hand, to meet the clamping support requirements for different pipes and improve the adaptability of the equipment, but more importantly, to maintain the existence of an air space between the pipe and the perforation 3 to avoid direct contact between the pipe and the pipe support 01, but to indirectly contact through the block 4; in the present application, the block 4 can be made of thermal insulation material, or a thermal insulation coating can be coated on the side of the block 4 in contact with the pipe. Since the thermal insulation material and the thermal insulation coating are both very mature in the prior art and can be purchased on the market, they will not be described in detail here.

[0030] In one embodiment, one end of the block 4 corresponding to the pipeline is provided with a flexible heat-insulating cushion layer 42. The flexible heat-insulating cushion layer 42 can be heat-insulating cotton.

[0031] In one embodiment, a plurality of pipe supports 01 are arranged side by side, and connection holes 5 are provided at corresponding heights on the sides of the upper support seat 1 and the lower support seat 2, and the connection holes 5 on two adjacent pipe supports 01 are coaxially aligned; a second screw rod 6 is provided between two adjacent pipe supports 01, and both ends of the second screw rod 6 are respectively screwed to the connection holes 5 on the pipe supports 01 on both sides.

[0032] In specific implementation, when multiple pipes are distributed side by side, the provision of the second screw rod 6 can, on the one hand, improve the overall stability and reliability between the pipe supports 01; on the other hand, the provision of the second screw rod 6 changes the installation order of the pipe supports 01, specifically: the first pipe support 01 can be fixed on the wall / support first, and then the second pipe support 01 can be fixed by the second screw rod 6 based on the first pipe support 01, and the second screw rod 6 can be rotated at the same time to change the position of the second pipe support 01 (it also ensures that the final multiple pipe supports 01 are aligned), and after the position of the second pipe support 01 is confirmed (the actual installation and docking process of the pipe is often accompanied by position adjustment and change, so that the final installation position has a slight deviation from the preset position on the drawing), the second pipe support 01 is fixed to the wall / support in turn.

[0033] In one embodiment, the threads at both ends of the second screw rod 6 have opposite rotation directions and are respectively screwed to the connecting holes 5 on the two adjacent pipe supports 01. Rotating the second screw rod 6 can control the two adjacent pipe supports 01 to move closer or farther away from each other. A rotating block 61 is provided in the middle of the second screw rod 6, and the second screw rod 6 is driven to rotate by the rotating block 61.

[0034] During the specific implementation, the worker rotates the rotating block 61 by hand or with a tool, thereby driving the second screw 6 to rotate; since the rotation directions of the two ends of the second screw 6 are opposite, the adjustment speed of the distance between the two adjacent pipe supports 01 can be accelerated. At the same time, after the two adjacent pipe supports 01 are fixed, a pulling force or a thrust can be applied to one side of the pipe support 01 by rotating the second screw 6, which can be used to balance the impact force at the corner of the pipe (when the liquid in the pipe is flowing, during the opening and closing process, under the water hammer effect, the pipe will vibrate, especially at the corner of the pipe, which is prone to a large impact force in a specific direction).

[0035] In one embodiment, the upper support seat 1 and the lower support seat 2 both include a seat plate 7 and a fixing plate 8 fixedly connected together, the semi-arc notch is provided on the fixing plate 8, and when the upper support seat 1 and the lower support seat 2 are put together, the fixing plates 8 are respectively located at two diagonally opposite positions of the pipe support 01, and are centrally symmetrical with the central axis of the through hole 3 as the axis; one end of the fixing plate 8 extends to the seat plate 7 opposite thereto, and the seat plate 7 and the end of the fixing plate 8 extending to the seat plate 7 are respectively provided with screw holes 9, and the upper support seat 1 and the lower support seat 2 are connected together by passing bolts through the screw holes 9;

[0036] The second screw rod 6 is connected to the fixing plates 8 on the upper support seat 1 and the lower support seat 2 of two adjacent pipe supports 01 respectively.

[0037] In a specific implementation, the connection method of the second screw rod 6 can not only connect the upper support seat 1 and the lower support seat 2, but also enhance the connection strength between the upper support seat 1 and the lower support seat 2, thereby improving the overall stability and reliability between the pipe supports 01; and the two diagonally arranged fixing plates 8 are precisely designed to cooperate with the second screw rod 6 to achieve this effect.

[0038] It should be pointed out that a spring pad or a flexible pad can be provided between the upper support seat 1 and the lower support seat 2 to provide a certain preload force between the upper support seat 1 and the lower support seat 2. At the same time, a certain displacement can be provided when the pipeline vibrates to avoid rigid contact with the pipeline and damage to the pipeline.

[0039] In one embodiment, the connection hole 5 passes through the side surfaces of the upper support seat 1 and the lower support seat 2 and is connected to the through hole 3. The first screw rod 41 and the second screw rod 6 have the same thread type and can be screwed into the connection hole 5. With this design, not all pipes need to be connected together using the second screw rod 6; for parts where pipe vibration is small (such as the middle part of the pipe and the large-diameter pipe at the diameter change), the second screw rod 6 on the pipe support 01 can also be omitted. At this time, if the pipe is arranged horizontally against the wall, the first screw rod 41 can be screwed into the connection hole 5 to achieve the upper and lower clamping of the pipe, better support the pipe, and further improve the applicability of the equipment.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
