Description

Technical Field

[0001] The utility model relates to the technical field of pipeline support, in particular to a pipeline support device for water conservancy project construction. Background Art

[0002] During the construction of water conservancy projects, pipes are often used for water delivery and drainage. When installing pipes, pipe supports are usually used to support them.

[0003] The existing pipe support generally includes a fixed support and an upper clamp and a lower clamp installed thereon, the lower clamp is fixedly connected to the fixed support, and the pipe is installed on the support bracket through the upper clamp and the lower clamp. However, when the upper clamp and the lower clamp are used to fix the pipe, they can only tighten the pipe whose radius is greater than or equal to the radius of the pipe, and cannot tighten the pipe whose radius is less than the clamp radius but whose height is higher than the clamp radius. The lower surface of the upper clamp cannot be in close contact with the outer surface of the pipe, causing the pipe to loosen; and the existing pipe cannot adjust its height through the pipe support, and can only adjust its height by placing a pad under the pipe support. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a pipeline supporting device for water conservancy project construction.

[0005] The technical solution of this utility model is as follows:

[0006] A pipe support device for water conservancy project construction comprises a support seat, an arc-shaped support bracket is arranged on the support seat, the arc-shaped support bracket is detachably connected to the support seat through a vertically arranged connecting piece, and the vertical height of the arc-shaped support bracket is adjustable;

[0007] An inverted V-shaped fixing piece is provided on the arc-shaped support bracket, and the lower surface of the V-shaped fixing piece and the upper surface of the arc-shaped support bracket form a clamping surface capable of clamping the pipe. The two ends of the V-shaped fixing piece are detachably connected to the two ends of the arc-shaped support bracket, and the vertical spacing between the V-shaped fixing piece and the arc-shaped support bracket is adjustable.

[0008] The lower outer surface of the pipeline is supported by an arc-shaped support bracket, and the upper part of the pipeline is pressed down and fixed by a V-shaped fixing piece. The two ends of the V-shaped fixing piece are connected to the corresponding two ends of the arc-shaped support bracket by bolts and other connecting parts, so that the V-shaped fixing piece can move up and down on the arc-shaped support bracket, thereby realizing the fixation of pipelines of different diameters. The highest point of the clamping position formed by the combination of the V-shaped fixing piece and the arc-shaped support bracket is lower than the highest point of the clamping position formed by two identical arc-shaped support brackets, and can clamp pipelines with a radius smaller than the radius of the arc-shaped support bracket but a height higher than the radius of the clamp, thereby reducing the phenomenon that the pipeline cannot be fixed due to the mismatch between the arc-shaped support bracket and the pipeline.

[0009] Regarding the specific structure of the V-shaped fixing, the V-shaped fixing includes two pressure plates which are symmetrically arranged and connected at the ends, and the angle between the two pressure plates is between 90° and 150 degrees. If the angle between the two pressure plates is less than 90°, it is not convenient to fix the pipe whose radius is smaller than the radius of the clamp and whose height is lower than the radius of the clamp.

[0010] When the angle between the two pressure plates is within the range of values, in order to facilitate the connection between the two ends of the V-shaped fixing member and the corresponding two ends of the arc-shaped support bracket, the ratio of the vertical height of the V-shaped fixing member to the radius of the arc-shaped support bracket is set to 1: (1-3).

[0011] In order to facilitate the lower surfaces of the two pressing plates to press down the outer surface of the pipeline at symmetrical positions, the vertical plane where the intersection of the two pressing plates is located coincides with the vertical plane where the center of the arc-shaped support bracket is located.

[0012] In order to improve the pressing and tightening effect on the pipeline, a tightening piece is provided at the intersection of the two pressing plates. The tightening piece is vertically arranged, and its lower end can pass through the pressing plate and abut against the outer surface of the pipeline.

[0013] Regarding the specific structure of the pressing member, the pressing member includes a fastening rod threadedly connected to the pressing plate, and the lower end of the fastening rod is rotatably connected to the arc-shaped lower pressing plate.

[0014] The structure of the arc-shaped lower pressing plate is that if the curvature of the arc-shaped lower pressing plate is too large, it is easy to touch the lower surfaces of the pressing plates on both sides. Therefore, the curvature of the arc-shaped lower pressing plate is set to be less than π / 6.

[0015] The beneficial effect of the utility model is that the arc-shaped support bracket is used to support the lower outer surface of the pipeline and play a supporting role. The V-shaped fixing piece is buckled on the outer surface of the upper part of the pipeline to fix the pipeline on the arc-shaped support bracket. When the V-shaped fixing piece is arranged above the pipeline and the two ends of the V-shaped fixing piece are aligned and connected with the two ends of the arc-shaped support bracket, compared with symmetrically arranging another arc-shaped support bracket above the arc-shaped support bracket, the lower surface of the V-shaped fixing piece in contact with the pipeline can be lower than the lower surface of the other arc-shaped support bracket in contact with the pipeline, so as to realize the pipeline whose radius is smaller than the radius of the arc-shaped support bracket but whose height is higher than the radius of the clamp, that is, the pipeline whose radius is slightly smaller than the arc-shaped support bracket can be pressed down and fixed;

[0016] The connecting piece is threadedly connected to the support seat, and the upper end of the connecting piece is fixedly connected to the middle position of the lower end of the arc-shaped support bracket. The connecting piece is a threaded rod, and a nut is provided on the threaded rod. By adjusting the nut, the height position of the threaded rod on the support seat can be adjusted, thereby realizing the arc-shaped support bracket driving the pipeline to move up and down and fine-tune the pipeline height.

[0020] 1. Support seat; 11. Horizontal plate; 2. Arc-shaped support bracket; 3. Connector; 4. Pressure plate; 5. Fastening rod; 6. Lower pressure plate; 7. Nut; 8. Bolt; 9. Pipeline. DETAILED DESCRIPTION

[0021] See also Figure 1 A pipeline support device for water conservancy project construction shown in the figure includes a support seat 1, on which an arc-shaped support bracket 2 is provided, and the arc-shaped support bracket 2 is detachably connected to the support seat 1 through a vertically arranged connecting piece 3, and the vertical height of the arc-shaped support bracket 2 is adjustable. The connecting piece 3 is threadedly connected to the support seat 1, and the upper end of the connecting piece 3 is fixedly connected to the middle position of the lower end of the arc-shaped support bracket 2. The connecting piece 3 is a threaded rod, and at least one transverse plate 11 is provided on the support seat 1. The threaded rod is threadedly connected to the transverse plate 11 respectively, and at least one nut 7 is provided on the threaded rod. Each transverse plate 11 is correspondingly provided with a nut 7. By adjusting the nut 7, the height position of the threaded rod on the support seat 1 can be adjusted, thereby realizing that the arc-shaped support bracket 2 drives the pipeline 9 to move up and down, and realizing fine-tuning of the height of the pipeline 9.

[0022] An inverted V-shaped fixing piece is provided on the arc-shaped support bracket 2, and the lower surface of the V-shaped fixing piece and the upper surface of the arc-shaped support bracket 2 form a clamping surface capable of clamping the pipe 9, the two ends of the V-shaped fixing piece are detachably connected to the two ends of the arc-shaped support bracket 2, and the vertical spacing between the V-shaped fixing piece and the arc-shaped support bracket 2 is adjustable.

[0023] The lower outer surface of the above-mentioned pipe 9 is supported by the arc-shaped support bracket 2, and the upper part of the pipe 9 is pressed down and fixed by a V-shaped fixing piece. The two ends of the V-shaped fixing piece are connected to the corresponding two ends of the arc-shaped support bracket 2 by bolts 8, so that the V-shaped fixing piece can move up and down on the arc-shaped support bracket 2, thereby realizing the fixation of pipes 9 of different diameters, and the height of the clamping surface formed by the combination of the V-shaped fixing piece and the arc-shaped support bracket 2 is lower than the height of the clamping surface formed by the buckling of two identical arc-shaped support brackets 2, and the arc-shaped support bracket 2 below is fixed unchanged. Therefore, the V-shaped fixing piece above the pipe 9 can clamp the pipe 9 with a radius smaller than the radius of the arc-shaped support bracket 2, thereby reducing the phenomenon that the pipe 9 cannot be fixed due to the mismatch between the arc-shaped support bracket 2 and the pipe 9.

[0024] Regarding the specific structure of the V-shaped fixing, the V-shaped fixing includes two pressure plates 4 that are symmetrically arranged and connected at the ends, and the angle between the two pressure plates 4 is between 90° and 150 degrees. When the angle between the two pressure plates 4 is within the value range, in order to facilitate the connection between the two ends of the V-shaped fixing and the corresponding two ends of the arc-shaped support bracket 2, the ratio of the vertical height of the V-shaped fixing and the radius of the arc-shaped support bracket 2 is set to 1: (1-3). In order to facilitate the lower surfaces of the two pressure plates 4 to press down on the outer surface of the pipeline at a symmetrical position, the vertical plane where the intersection of the two pressure plates 4 is located coincides with the vertical plane where the center of the arc-shaped support bracket 2 is located.

[0025] In the above, the upper surface of the pipe 9 is pressed down by contact only through two pressing plates 4. In order to improve the pressing and tightening effect of the entire pipe 9 and increase the pressing and fixing position of the pipe 9, a tightening member is provided at the intersection of the two pressing plates 4. The tightening member is vertically arranged, and its lower end can pass through the pressing plate 4 and abut against the outer surface of the pipe 9.

[0026] Regarding the specific structure of the top tightening member, the top tightening member includes a fastening rod 5 threadedly connected to the pressure plate 4, and the lower end of the fastening rod 5 is rotatably connected to an arc-shaped lower pressure plate 6. The rotational connection method between the fastening rod 5 and the arc-shaped lower pressure plate 6 is the existing technology and will not be repeated here. When the fastening rod 5 is rotated, the arc-shaped lower pressure plate 6 can be tightly attached to the surface of the pipeline without rotating. The structure of the above-mentioned arc-shaped lower pressure plate 6 is that the curvature of the arc-shaped lower pressure plate 6 is too large and it is easy to touch the lower surfaces of the pressure plates 4 on both sides. For this reason, the curvature of the arc-shaped lower pressure plate 6 is set to be less than π / 6.
