Description

[Technical field]

[0001] The utility model belongs to the technical field of pipeline installation, and in particular relates to a pipeline support damping and vibration reduction bracket with adjustable height. [Background technology]

[0002] As an important support for erecting various types of pipelines, pipe supports are widely used in many fields such as metallurgy, chemical industry, and municipal administration. When installing pipelines and supports, the supports are generally selected or designed based on the pipelines. However, after errors occur due to installation or foundation reasons, since the supports are selected or designed in advance, they cannot be temporarily adjusted, resulting in the support being unable to stably support the pipelines, which seriously affects the installation quality of the pipelines. In the later use, there will also be insufficient support or uneven force on the pipelines, which may affect or damage the pipelines. At the same time, due to the reciprocating motion of the airflow, there is also a risk of vibration in the compressor pipeline. [Contents of the utility model]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a height-adjustable pipeline support damping and vibration reduction bracket to avoid the impact or damage to the pipeline caused by insufficient pipeline support or uneven force due to the inability to adjust the pipeline height.

[0005] Preferably, the first height adjustment slot and the second height adjustment slot extend obliquely; and / or the locking member is a pull rod bolt.

[0006] Preferably, the first height adjustment slot and the second height adjustment slot have opposite inclination directions and complementary angles.

[0009] Preferably, the clamp bracket includes two angle steels welded side by side to the bottom of the clamp bracket, and the second height adjustment groove is arranged on the side wall of the angle steel.

[0010] Preferably, a through hole is provided on the bottom wall of the angle steel, and a jacking bolt and a locking nut are connected to the through hole.

[0011] Preferably, the pipeline support damping and vibration reduction bracket is provided with two clamps spaced apart along the axial direction of the pipeline; and / or the damping and shock absorbing component is a metal rubber pad.

[0012] Preferably, the metal rubber pad is woven from metal rubber wires.

[0013] Preferably, the metal rubber pad is a half-structure and is respectively placed on the inner sides of the two clamps.

[0014] The utility model adopts the above technical solution and has the following beneficial effects:

[0027] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] Reference Figures 1 to 3As shown, this embodiment provides a height-adjustable pipeline support damping and vibration-isolating bracket, including a clamp 4 for clamping the pipeline, a damping and shock-absorbing member arranged between the clamp and the pipeline, a clamp bracket connected to the bottom of the clamp, a base 1 arranged under the clamp, and a height adjustment structure arranged between the base 1 and the clamp bracket.

[0029] Among them, the height adjustment structure includes a first height adjustment groove 13 arranged on the base, a second height adjustment groove 14 arranged on the clamp bracket, and a locking member connecting the first height adjustment groove 13 and the second height adjustment groove 14. The locking member locks the first height adjustment groove 13 and the second height adjustment groove 14 after the clamp bracket adjusts the height.

[0030] Referring to the clamp structure in the prior art, the clamp 4 is a split-half structure consisting of two semicircular parts, which are fixed as a whole by the clamp bolts 5 and simultaneously hold the pipe tightly.

[0031] Due to the height adjustment structure between the base and the clamp bracket, when the locking piece is loosened, the first height adjustment slot and the second height adjustment slot can be relatively adjusted up and down. After being adjusted in place, the locking piece is locked again to fix the relative position between the first height adjustment slot and the second height adjustment slot. Therefore, the pipe bracket provided by the utility model can achieve height adjustment, so that the pipe bracket can adapt to various installation conditions, improve the supporting performance of the pipe, and avoid the influence or damage to the pipe caused by insufficient pipe support or uneven force due to the inability to adjust the pipe height.

[0032] In addition, due to the damping and shock absorbing member between the clamp and the pipeline, the pipeline support provided by the utility model has a certain damping and vibration reduction function, which can reduce the vibration level of the pipeline.

[0033] As an implementation mode, the first height adjustment slot 13 and the second height adjustment slot 14 extend obliquely. The widths of the first height adjustment slot and the second height adjustment slot are equal, and the locking member passes through the first height adjustment slot and the second height adjustment slot. When the first height adjustment slot and the second height adjustment slot are adjusted up and down relative to each other, the axial position also changes relatively, so that the axial position can be adjusted while the height is adjusted. Since the height and axial position can be adjusted at the same time, the pipe support can adapt to various installation conditions and improve the supporting performance of the pipe.

[0034] In order to facilitate height adjustment, the locking member is a tie rod bolt 7, which passes through the first height adjustment slot 13 and the second height adjustment slot 14. Therefore, the diameter of the tie rod bolt is smaller than the width of the first height adjustment slot and the second height adjustment slot. The height can be adjusted by loosening the tie rod bolt, and it is locked and fixed after the adjustment is completed.

[0035] Among them, the inclination directions of the first height adjustment slot 13 and the second height adjustment slot 14 are opposite and the angles are complementary. Specifically, the angles of the first height adjustment slot and the second height adjustment slot to the ground are 180-θ and θ respectively, where 0≤θ≤45°. In this way, the effect of preventing loosening and dislocation is achieved. Of course, the first height adjustment slot 13 and the second height adjustment slot 14 can also be arranged vertically, and positioning slots are distributed along the vertical direction for cooperation with locking members, such as bolts. After the first height adjustment slot and the second height adjustment slot are adjusted up and down relative to each other and positioned in the positioning slots, the bolts pass through the positioning slots for locking and fixing.

[0036] In this embodiment, the pipeline support damping and vibration reduction bracket is provided with two clamps 4 at intervals along the axial direction of the pipeline. In addition, since the two clamps are welded to the clamp bracket as one, the fixation is reliable and the supporting effect is better.

[0037] Specifically, the base 1 is provided with a rectangular groove, and the first height adjustment groove 13 is provided on the two length side walls of the rectangular groove. The base 1 is provided with a bottom plate, which is a rectangular steel plate and has a size larger than the rectangular groove. Four baffles are welded on the bottom plate and enclosed to form a rectangular groove, including a first short vertical plate 9 and a second short vertical plate 10 located on both sides of the length and a first long vertical plate 11 and a second long vertical plate 12 located on both sides of the width. Among them, two through-type first height adjustment grooves 13 are opened on both sides of the middle and upper length of the first long vertical plate 11 and the second long vertical plate 12. The angles of the two first height adjustment grooves 13 on each long vertical plate with the ground are θ and 180-θ, respectively, where 0≤θ≤45°. The two first height adjustment grooves 13 at the corresponding length positions of the first long vertical plate 11 and the second long vertical plate 12 are consistent with the ground angle.

[0038] Specifically, the clamp bracket includes two angle steels 6 welded side by side at the bottom of the clamp bracket, and the second height adjustment slots 14 are provided on the side walls of the angle steels. Two second height adjustment slots 14 are provided along the length direction of each angle steel, and the angles with the ground are θ and 180-θ respectively, where 0≤θ≤45°. Thus, the number of the second adjustment slots 14 on the two angle steels corresponds to the number of the first height adjustment slots 13 on the two long vertical plates.

[0039] like Figure 3 As shown, the distance d1 between the two angle steels 6 is ≥ the distance d2 between the two long vertical plates, and the length L of the tie bolt is greater than 1.2*d1 to ensure that the two long vertical plates are located within the distance between the two angle steels, and the angle steels and the long vertical plates are locked and fixed by the tie bolts.

[0040] Furthermore, a through hole is provided on the bottom wall of the angle steel 6, and the through hole is connected with a jacking bolt 2 and a locking nut 3. After the jacking bolt 2 is rotated to a suitable height, the jacking bolt is supported against the bottom plate, and then the nut is locked 3, thereby maintaining the relative height of the clamp bracket, and cooperating with the locking piece to ensure that the height can be maintained after the height adjustment is completed.

[0041] It can be understood that the minimum distance between the first height adjustment slot 13 and the through hole on each long vertical plate is ≥ the outer diameter of the tie rod bolt nut to avoid interference.

[0042] The damping shock absorbing member is a metal rubber pad 8. The metal rubber pad 8 is woven from metal rubber wire. It has both the inherent properties of the selected metal and the elasticity like rubber. The load and deformation relationship is nonlinear, that is, the stiffness gradually softens, which will reduce the "natural frequency" in the spatial direction of the system. As the magnitude of the external excitation increases, the "natural frequency" decreases, so it has a good vibration isolation effect; the damping increases significantly in the resonance area, which can effectively suppress the resonance peak, and the damping decreases rapidly in the vibration isolation area, so it has excellent damping and vibration reduction characteristics.

[0043] In addition, the metal rubber pad is a half-structure and is respectively placed on the inner sides of the two clamps.

[0044] For the above-mentioned height-adjustable pipeline support damping vibration reduction bracket, the installation and adjustment steps are as follows:

[0045] S1: a metal rubber pad 8 is arranged inside the clamp 4;

[0046] S2: The pipe is fixed with a clamp 4;

[0047] S3: Place the clamp 4 and the angle steel 6 on both sides of the long vertical plate of the base 1;

[0048] S4: Set a locking nut 3 and a jacking bolt 2 on the bottom wall through hole of the angle steel 6; rotate the jacking bolt 2 to a suitable height, and lock the nut 3;

[0049] S5: Pass the two tie rod bolts 7 through the corresponding first height adjustment slot and the second height adjustment slot respectively; adjust the position of the tie rod bolts until the clamp is in a suitable position.

[0050] The height-adjustable damping vibration reduction bracket of the utility model has a simple structure and is easy to construct, which can speed up the progress of on-site construction and meet the demand for achieving adjustable pipeline installation elevation.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
