Description

Technical Field

[0001] This utility model relates to the field of petrochemical pipeline technology, specifically to a petrochemical pipeline installation support. Background Technology

[0002] Petrochemical pipeline installation supports are pipe fittings used to support pipelines, limit their displacement, and transfer pipeline loads to building structures or the ground. Their core function is to ensure the stability, safety, and vibration resistance of the pipeline system. The helical springs installed inside the supports are prone to aging over time, leading to reduced vibration damping effects and necessitating periodic replacement. However, existing supports typically require complete removal for replacement, reducing replacement efficiency. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a petrochemical pipeline installation support that solves the problem that the helical springs installed inside the installation support are prone to aging due to long-term operation, resulting in a decrease in shock absorption effect and the need for periodic replacement. However, existing supports usually require complete removal of the support before replacement, which reduces the efficiency of replacement.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a petrochemical pipeline installation support, comprising a shock-absorbing base and a lower support. The shock-absorbing base has a damping rod and a helical spring installed inside, with a connecting rod connected above the damping rod and helical spring. The upper half of the shock-absorbing base has a second damping rod and a second helical spring installed on its inner side, with a sliding rod connected to the top of the second helical spring. A rubber pad is inserted into the top of the shock-absorbing base. The lower support is installed above the connecting rod, and a connecting block is integrally formed at the connection point between the lower support and the connecting rod. A limit baffle is bolted to the connecting block. An upper support is bolted to the top of the lower support. Both the lower and upper supports are filled with an insulation layer, and a thermal insulation pad is bonded to the inner sides of both supports.

[0005] The beneficial effects of this utility model are as follows: the damping rod one and the helical spring one work together to connect the rod to absorb the main vibration, the damping rod two and the helical spring two work together to assist the damping rod one and the helical spring one in damping, and the rubber pad block absorbs the lateral vibration of the device. In this way, the purpose of shock absorption and support is achieved.

[0006] When the shock absorber base needs to be replaced, unscrew the fixing bolts at the bottom of the shock absorber base, unscrew the bolts on the limit baffle, remove the limit baffle, and push the shock absorber base out along the oil pipeline. The shock absorber base can then be repaired or replaced. This method can increase the efficiency of shock absorber base repair and replacement.

[0007] To ensure shock absorption:

[0008] As a further improvement to the above technical solution: the connecting rod and the helical spring are arranged with their axes coincident.

[0009] As a further improvement to the above technical solution: the sliding rod is symmetrically arranged about the center line of the shock-absorbing base.

[0010] The beneficial effects of this improvement are as follows: by aligning the connecting rod with the axis of the first helical spring, the connecting rod can transmit vibration to the first helical spring and the first damping rod. The symmetrically arranged sliding rods ensure the reliability of the auxiliary damping effect of the sliding rods in conjunction with the second damping rod and the second helical spring.

[0011] To facilitate the installation of the connecting rod:

[0012] As a further improvement to the above technical solution: a guide groove is provided on the connecting block near the connecting rod.

[0013] As a further improvement to the above technical solution: the connecting block and the connecting rod form a snap-fit ​​installation structure through a guide groove.

[0014] The beneficial effects of this improvement are: the guide groove can guide and limit the connection between the connecting rod and the connecting block, ensuring the efficiency and position of the disassembly and installation of the connecting rod.

[0015] To increase structural strength:

[0016] As a further improvement to the above technical solution: the lower half of the shock-absorbing base is provided with ribs in the circumferential direction.

[0017] The beneficial effects of this improvement are: the circumferentially arranged ribs can strengthen the damping base and increase its load-bearing capacity.

[0018] To ensure shock absorption:

[0019] As a further improvement to the above technical solution: the second damping rod and the second helical spring are symmetrically arranged about the center line of the sliding rod.

[0020] As a further improvement to the above technical solution: the damping rod two and the helical spring two are arranged with their axes coincident.

[0021] The beneficial effects of this improvement are: the damping rod and the helical spring can absorb the vibration transmitted by the sliding rod, ensuring the damping effect formed by the damping rod and the helical spring in conjunction with the sliding rod. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0029] like Figure 1-5As shown, a petrochemical pipeline installation support includes a shock-absorbing base 1 and a lower support 2. The shock-absorbing base 1 has a damping rod 11 and a helical spring 12 installed inside, with a connecting rod 13 connected above the damping rod 11 and helical spring 12. The upper half of the shock-absorbing base 1 has a second damping rod 14 and a second helical spring 15 installed on its inner side, with a sliding rod 16 connected to the top of the second helical spring 15. A rubber pad 17 is inserted into the top of the shock-absorbing base 1. The lower support 2 is installed above the connecting rod 13, and a connecting block 21 is integrally formed at the connection between the lower support 2 and the connecting rod 13. A limit baffle 22 is bolted onto the connecting block 21. An upper support 3 is bolted onto the upper part of the lower support 2. Both the lower support 2 and the upper support 3 are filled with an insulation layer 4, and a heat-insulating pad 41 is bonded to the inner side of the lower support 2 and the upper support 3. The damping rod 11 and the helical spring 12 are connected to a connecting rod 13. The first spring 12, in conjunction with the connecting rod 13, absorbs the main vibration. The second damping rod 14, in conjunction with the second helical spring 15, and the sliding rod 16, assist the first damping rod 11 and the helical spring 12 in damping. The rubber pad 17 absorbs the lateral vibration of the device. This method serves the purpose of shock absorption and support. When it is necessary to replace the shock-absorbing base 1, unscrew the fixing bolts at the bottom of the shock-absorbing base 1, unscrew the bolts on the limiting baffle 22, remove the limiting baffle 22, and push the shock-absorbing base 1 out along the oil pipeline. Then, the shock-absorbing base 1 can be repaired and replaced. This method can increase the efficiency of repairing and replacing the shock-absorbing base 1. The connecting rod 13 and the helical spring 12 are set with their axes coincident. The sliding rod 16 is symmetrically arranged about the center line of the shock-absorbing base 1. By setting the axes of the connecting rod 13 and the helical spring 12 coincidentally, the connecting rod 13 can transmit the vibration to the helical spring 12 and the damping rod 11. The symmetrically arranged sliding rod 16 ensures the reliability of the damping effect of the sliding rod 16 in conjunction with the damping rod 14 and the coil spring 15. The connecting block 21 has a guide groove near the connecting rod 13. The connecting block 21 and the connecting rod 13 form a snap-fit ​​installation structure through the guide groove. The guide groove can guide and limit the connection when the connecting rod 13 is connected to the connecting block 21, ensuring the efficiency and position of the disassembly and installation of the connecting rod 13. The lower half of the shock-absorbing base 1 is provided with circumferential ribs, which can strengthen the shock-absorbing base 1 and increase its load-bearing capacity. The damping rod 14 and the coil spring 15 are symmetrically arranged about the center line of the sliding rod 16. The damping rod 14 and the coil spring 15 are arranged with their axes coincident. The damping rod 14 and the coil spring 15 can absorb the vibration transmitted by the sliding rod 16, ensuring the shock absorption effect formed by the damping rod 14, the coil spring 15 and the sliding rod 16.

[0030] The working principle of this utility model is as follows: When using this device, the shock-absorbing base 1 is installed below the oil pipeline. Then, the lower support 2 is inserted into the upper part of the connecting rod 13. Bolts are used in conjunction with the limiting baffle 22 to connect and fix the connecting rod 13 and the lower support 2. After fixing, bolts are used to install the upper support 3 above the lower support 2. During the operation of the device, the heat insulation layer 4, together with the heat insulation pad layer 41, provides heat insulation for the support. The damping rod 11 and the helical spring 12 work together with the connecting rod 13 to absorb the main vibration. The damping rod 214 and the helical spring 12 work together to absorb the main vibration. Spring 15, in conjunction with sliding rod 16, assists damping rod 11 and helical spring 12 in shock absorption, while rubber pad 17 absorbs lateral vibrations. This method serves as a shock-absorbing support. When the shock-absorbing base 1 needs to be replaced, unscrew the fixing bolts at the bottom of the shock-absorbing base 1, unscrew the bolts on the limiting baffle 22, remove the limiting baffle 22, and push the shock-absorbing base 1 out along the oil pipeline. This method can increase the efficiency of repairing and replacing the shock-absorbing base 1.
