Description

Technical Field

[0002] On ships, double-walled pipes are usually used to transport liquids or gases and to perform heat exchange processes. Double-walled pipes are usually composed of two pipes, the inner pipe is used to transport fluids, and the outer pipe is used to maintain the temperature of the fluid or prevent fluid leakage. When installing double-walled pipes, it is necessary to ensure that their installation position is accurate and the support is stable to ensure their normal operation and safety and reliability in use.

The support block is installed on a panel, and the brackets are arranged on both sides of the bottom of the panel; the cover plate is removably installed on the upper end of the support block. The cover plate is a semicircular plate, and a semicircular groove is arranged on the upper end of the support block. The thickness of the two side walls of the semicircular groove is greater than the thickness of the bottom of the semicircular groove.

[0050] See also Figure 1 As shown, the double-walled pipe fixing device according to the embodiment of the utility model includes a first support base 100 , a second support base 200 and a vibration reduction mechanism 300 .

[0051] The first support seat 100 is used to fix the double-walled pipe 10. The second support seat 200 is used to be fixed on the installation base, and the second support seat 200 is arranged opposite to the first support seat 100. The vibration reduction mechanism 300 is arranged between the first support seat 100 and the second support seat 200, and the vibration reduction mechanism 300 includes a damper 310 and an elastic buffer part 320, and the two ends of the damper 310 are respectively connected to the first support seat 100 and the second support seat 200, and the elastic buffer part 320 is fixedly installed between the first support seat 100 and the second support seat 200 and elastically supports the first support seat 100.

[0052] It should be noted that in the present application, the installation base surface may refer to the surface of the hull structure or the equipment surface where the double-walled pipe 10 is installed on the ship. The double-walled pipe fixing device of the present application is used to be fixedly installed on the installation base surface to fix the double-walled pipe at the required installation position on the ship.

[0053] The double-walled pipe fixing device of the embodiment of the present application includes a first support seat 100, a second support seat 200, and a vibration reduction mechanism 300 disposed between the first support seat 100 and the second support seat 200. Through the coordinated arrangement of the first support seat 100, the second support seat 200 and the vibration reduction mechanism 300, a vibration reduction and buffering function is provided between the first support seat 100 and the second support seat 200, which effectively reduces the influence of external vibration and vibration on the double-walled pipe 10, and is conducive to maintaining the stability of the pipeline system. Thereby, the service life of the pipeline can be effectively extended, the maintenance cost of the pipeline system can be reduced, and the safety and reliability of the system can be improved.

[0054] The vibration reduction mechanism 300 includes a damper 310 and an elastic buffer 320. The damper 310 can buffer and reduce the relative movement caused by external shock and vibration between the first support seat 100 and the second support seat 200. The elastic buffer 320 enables the second support seat 200 to elastically support the first support seat 100, further eliminating the influence of external vibration on the double-walled pipe 10.

[0055] like Figure 1 As shown, in the implementation of the present application, the double-walled pipe fixing device further includes a base 600, and the base 600 is used to support and set the first support base 100, the second support base 200 and the vibration reduction mechanism 300. The base 600 may have a rectangular shape.

[0056] Specifically, the base 600 is used for fixed installation with the installation base surface. Optionally, the base 600 can be detachably fixedly installed with the installation base surface by means of a screw structure.

[0057] The second support base 200 is supported and arranged on the base 600. The second support base 200 is fixed on the installation base surface through the base 600. The second support base 200 may have a rectangular shape.

[0058] See also Figure 1 In one embodiment, the double-walled pipe fixing device further includes an adjustment mechanism 500 , which is disposed between the second support seat 200 and the installation base surface. Specifically, the adjustment mechanism 500 is disposed between the second support seat 200 and the base 600 .

[0059] In this embodiment, the adjustment mechanism 500 is mainly used to adjust the height of the second support seat 200 relative to the installation base. Since the height of the second support seat 200 relative to the installation base is adjustable, the height position of the first support seat 100 relative to the installation base can also be adjusted as needed, so that the first support seat 100 can fix the double-walled pipe 10 at different heights. In this embodiment, by setting the adjustment mechanism 500, the double-walled pipe fixing device can be adjusted to a suitable height according to the laying position of the double-walled pipe 10, which effectively improves the practicality of the device.

[0060] See also Figure 1 In one embodiment, the adjustment mechanism 500 includes an adjustment rod 510, one end of which is used to be fixed on the mounting base, and the other end of the adjustment rod 510 is connected to the second support base 200. The length of the adjustment rod 510 is adjustable, so that the height position of the second support base 200 relative to the mounting base can be adjusted.

[0061] Specifically, one end of the adjusting rod 510 away from the second supporting seat 200 is fixedly connected to the base 600. Since the length of the adjusting rod 510 is adjustable, the second supporting seat 200 can be lifted and lowered relative to the base 600 when the length of the adjusting rod 510 changes. Thus, the height of the second supporting seat 200 relative to the installation base can be adjusted by changing the length of the adjusting rod 510.

[0062] For example, one end of the adjustment rod 510 may be connected to the middle of the base 600. The other end of the adjustment rod 510 may be connected to the middle of the second support seat 200. That is, the adjustment rod 510 is disposed at the center of the base 600.

[0063] like Figure 1 As shown, in one embodiment, the specific manner in which the length of the adjusting rod 510 can be adjusted can be: the adjusting rod 510 includes a screw portion 511 and a sleeve portion 512, one end of the screw portion 511 is fixedly connected to the base 600, the other end of the screw portion 511 is threadedly connected to one end of the sleeve portion 512, and the other end of the sleeve portion 512 is rotatably connected to the second support seat 200. Since the screw portion 511 and the sleeve portion 512 are threadedly connected. When the sleeve portion 512 is rotated, the thread matching depth of the screw portion 511 and the sleeve portion 512 can be changed, so that the length of the adjusting rod 510 changes, and then the height position of the second support seat 200 can be adjusted as needed.

[0064] In other embodiments, the length of the adjusting rod 510 can be adjusted in a specific manner as follows: the adjusting rod 510 may include a first rod body and a second rod body connected to each other. The first rod body is provided with a plurality of connecting holes along the axial direction. The second rod body is provided with a connecting through hole. Fasteners such as screws are inserted into the connecting through holes and fastened to any of the connecting holes, so that the length of the adjusting rod 510 can be adjusted as needed.

[0065] like Figure 1 As shown, for example, the adjustment rod 510 further includes an adjustment handle 513. The adjustment handle 513 can be fixedly arranged on the outer peripheral wall of the sleeve portion 512. By providing the adjustment handle 513, it is convenient to rotate the sleeve portion 512, thereby facilitating the adjustment operation of the length of the adjustment rod 510.

[0066] In other embodiments, the adjusting rod 510 may also be replaced by a telescopic cylinder or an electric telescopic rod, etc., as long as the height position of the second supporting base 200 relative to the installation base surface is adjustable.

[0067] See also Figure 1 In one embodiment, the adjustment mechanism 500 further includes a guide rod 520, the two ends of which are respectively connected to the first support seat 100 and the base 600, and the guide rod 520 is used to guide the lifting movement of the second support seat 200 relative to the base 600. For example, the guide rod 520 may include a rod body 521 and a guide sleeve 522, and the rod body 521 and the guide sleeve 522 are slidably connected.

[0068] In this embodiment, the guide rod 520 is provided to provide guidance and limitation for the lifting and lowering process of the second support base 200 , thereby ensuring the stability of the height position adjustment of the second support base 200 .

[0069] There may be two guide rods 520. The two guide rods 520 may be respectively disposed on both sides of the adjustment rod 510. For example, the two guide rods 520 may be symmetrically distributed about the central axis of the adjustment rod 510. Such a configuration may help improve the stability of the lifting movement of the second support seat 200 relative to the base 600.

[0070] In the embodiment of the present application, the first support base 100 is supported by the vibration reduction mechanism 300 and is disposed above the second support base 200. The first support base 100 may have a rectangular shape.

[0071] The first support base 100 is used to fix the double-walled pipe 10. Figure 1 As shown, in one embodiment, the double-walled pipe fixing device further includes a limiting mechanism 400 disposed on the first support seat 100 , and the limiting mechanism 400 is used to limit and fix the double-walled pipe 10 .

[0072] The limiting mechanism 400 includes a first limiting seat 410 and a second limiting seat 420 which are connected relative to each other, and the first limiting seat 410 is fixedly mounted on the first supporting seat 100. Specifically, the first limiting seat 410 and the second limiting seat 420 are connected relative to each other to form an annular structure for embracing the outer periphery of the double-walled tube 10. The first limiting seat 410 is fixedly mounted on the first supporting seat 100, so that the double-walled tube 10 can be fixed to the first supporting seat 100.

[0073] The surface of the first stopper 410 and the second stopper 420 facing each other is a curved surface that matches the outer circumference of the double-walled tube 10. The surface of the second stopper 420 and the first stopper 410 facing each other is a curved surface that matches the outer circumference of the double-walled tube 10. By designing the surfaces of the first stopper 410 and the second stopper 420 that match the outer circumference of the double-walled tube 10 as matching curved surfaces, the double-walled tube 10 can be effectively limited and fixed.

[0074] In the present application, the surface of the first stopper 410 and the second stopper 420 opposite to each other is a curved surface matching the outer circumference of the double-walled tube 10. The surface of the second stopper 420 and the first stopper 410 opposite to each other is a curved surface matching the outer circumference of the double-walled tube 10. The overall appearance of the first stopper 410 and the second stopper 420 is not specifically limited.

[0075] See also Figure 2 As shown, in one embodiment, a first buffer pad 411 is provided on the surface opposite to the first limit seat 410 and the second limit seat 420. The first buffer pad 411 can be made of rubber. By providing the first buffer pad 411 on the surface where the first limit seat 410 contacts the outer circumference of the double-walled tube 10, the first limit seat 410 and the double-walled tube 10 are in elastic extrusion contact, thereby playing a role of buffering and vibration reduction, and effectively protecting the double-walled tube 10.

[0076] A second buffer pad 421 is provided on the surface of the second limit seat 420 opposite to the first limit seat 410. The second buffer pad 421 can be made of rubber. By providing the second buffer pad 421 on the surface of the second limit seat 420 in contact with the outer peripheral surface of the double-walled tube 10, the second limit seat 420 and the double-walled tube 10 are in elastic extrusion contact, thereby playing a role of buffering and vibration reduction, and effectively protecting the double-walled tube 10.

[0077] In the embodiment of the present application, the first buffer pad 411 and the second buffer pad 421 may be made of rubber material, but the present application is not limited thereto, and in other embodiments, the first buffer pad 411 and the second buffer pad 421 may also be made of elastic materials such as silicone, foam, etc., depending on the specific situation.

[0078] See also Figure 2In one embodiment, the relative connection mode of the first limit seat 410 and the second limit seat 420 can be: first protrusions 412 are respectively protruded on both sides of the first limit seat 410, and second protrusions 422 are respectively protruded on both sides of the second limit seat 420, and the two first protrusions 412 correspond to the two second protrusions 422 one by one.

[0079] Combination Figure 3 As shown, one of the first protrusions 412 is hingedly connected to the corresponding second protrusion 422. Specifically, a hinge seat 413 is provided on the first protrusion 412, and a hinge hole is provided on the hinge seat 413. A through hole is provided on the second protrusion 422 corresponding to the first protrusion 412, and a shaft member such as a pin is inserted into the hinge hole and the through hole to realize the hinged connection between the first protrusion 412 and the corresponding second protrusion 422.

[0080] like Figure 2 As shown, another first protrusion 412 is detachably connected to the corresponding second protrusion 422. Specifically, threaded holes may be provided on the first protrusion 412 and the corresponding second protrusion 422. By using fasteners such as bolts 430 to penetrate the threaded holes on the first protrusion 412 and the corresponding second protrusion 422, the detachable fixed connection between the first protrusion 412 and the corresponding second protrusion 422 can be achieved.

[0081] In this embodiment, when the limiting mechanism 400 is connected to the double-walled tube 10, the bolt 430 is first unscrewed so that the first limiting seat 410 and the second limiting seat 420 can be flipped open, and then the double-walled tube 10 is clamped in the inner arc surface of the first limiting seat 410, and then the second limiting seat 420 is flipped and reset. The first limiting seat 410 and the second limiting seat 420 are then locked by the bolt 430, so that the double-walled tube 10 is fixedly limited between the first limiting seat 410 and the second limiting seat 420. By setting the relative connection mode of the first limiting seat 410 and the second limiting seat 420 to be detachable on one side and hingedly connected on the other side, the fixing operation of the limiting mechanism 400 on the double-walled tube 10 can be more convenient, which is conducive to improving the convenience of use of the device.

[0082] In other embodiments, the two first protrusions 412 on both sides of the first limit seat 410 and the two second protrusions 422 on both sides of the second limit seat can be detachably fixedly connected. For example, the two first protrusions 412 and the corresponding second protrusions 422 can be detachably fixedly connected by screw structures. It can be understood that the screw structure can also be replaced by other detachable connection structures, such as a snap-on structure or a magnetic structure.

[0083] In the embodiment of the present application, the limiting mechanism 400 includes a first limiting seat 410 and a second limiting seat 420 connected relatively to each other. However, the present application is not limited thereto. In other embodiments, the structural form of the limiting mechanism 400 may be determined according to specific circumstances. For example, the limiting mechanism 400 may include three arc-shaped plates connected end to end in sequence, and the three arc-shaped plates may form an annular structure arranged around the outer periphery of the double-walled tube 10.

[0084] In the embodiment of the present application, the vibration reduction mechanism 300 is disposed between the first support base 100 and the second support base 200. The vibration reduction mechanism 300 includes a damper 310. For example, the number of the dampers 310 may be four. The four dampers 310 may be disposed at the four corners of the second support base 200, respectively.

[0085] See also Figure 4 In one embodiment, a mounting hole 230 for fixing and mounting one end of the damper 310 is provided on the surface of the second support base 200 opposite to the first support base 100. For example, the number of the mounting holes 230 may be four. The four mounting holes 230 may be respectively disposed at the four corners of the second support base 200 to mount the four dampers 310 in a one-to-one correspondence.

[0086] like Figure 5 As shown, the other end of the damper 310 protrudes out of the mounting hole 230 toward one side of the first support base 100 and is connected to the first support base 100. When the double-walled tube 10 is affected by external factors and vibrates, the vibration will be transmitted to the damper 310 between the second support base 200 and the first support base 100, and the purpose of buffering and vibration reduction can be achieved through the damper 310.

[0087] In the embodiment of the present application, the vibration reduction mechanism 300 further includes an elastic buffer portion 320. Figure 1 and Figure 6 As shown, in one embodiment, the elastic buffer portion 320 includes a plurality of first buffer columns 321 , and the plurality of first buffer columns 321 are installed in parallel and spaced apart between the first support seat 100 and the second support seat 200 .

[0088] The first buffer column 321 may be made of rubber material. The first buffer column 321 may be a cylindrical structure.

[0089] The outer circumferential surface of each first buffer column 321 is respectively against the first support seat 100 and the second support seat 200, so that the first support seat 100 and the second support seat 200 are arranged at a distance. By providing a plurality of first buffer columns 321, the second support seat 200 can play the role of elastic support for the first support seat 100, so that the second support seat 200 and the first support seat 100 are always kept at a distance. Therefore, when the double-walled pipe 10 is affected by external factors and vibrates, the first buffer column 321 between the second support seat 200 and the first support seat 100 can effectively absorb the impact of the vibration, thereby achieving the purpose of buffering and vibration reduction.

[0090] For example, a plurality of first buffer columns 321 may be evenly spaced between the first support seat 100 and the second support seat 200 , so that the elastic support effect of the second support seat 200 on the second support seat 200 is evenly distributed, thereby ensuring the buffering and shock absorbing effect.

[0091] like Figure 4 and Figure 6 As shown, in one embodiment, a plurality of first mounting grooves 210 for mounting the first buffer column 321 are provided on the surface of the second support seat 200 opposite to the first support seat 100. The groove surface of the first mounting groove 210 is designed as an arc surface matching the outer circumferential surface of the first buffer column 321. By fixing the plurality of first buffer columns 321 in the plurality of first mounting grooves 210, the reliable installation of each first buffer column 321 is ensured.

[0092] like Figure 6 As shown, a plurality of first grooves 110 for contacting with the outer circumference of the first buffer column 321 are provided on the surfaces opposite to the first support seat 100 and the second support seat 200, and each first mounting groove 210 is opposite to each first groove 110. The groove surface of the first groove 110 is designed as an arc surface matching the outer circumference of the first buffer column 321. By providing the first groove 110, when the first buffer column 321 is fixedly installed in the first mounting groove 210, the outer circumference of the first buffer column 321 away from the first mounting groove 210 can contact the first groove 110, thereby ensuring reliable support of the first buffer column 321 to the first support seat 100.

[0093] For example, each first buffer column 321 may be fixedly connected to the corresponding first groove 110. When the first buffer column 321 is fixedly installed in the first mounting groove 210, the outer peripheral surface of the first buffer column 321 away from the first mounting groove 210 contacts and is fixedly connected to the first groove 110, which can ensure that the first buffer column 321 reliably supports the first support seat 100.

[0094] In other embodiments, each first buffer column 321 and the corresponding first groove 110 may only be in a relationship of being able to abut against each other.

[0095] See also Figure 1 and Figure 6 As shown, in one embodiment, the elastic buffer portion 320 further includes a plurality of second buffer columns 322, which are installed in parallel and spaced apart between the first support seat 100 and the second support seat 200. The plurality of second buffer columns 322 are arranged alternately with the plurality of first buffer columns 321. The radial dimension of each second buffer column 322 is smaller than the radial dimension of each first buffer column 321.

[0096] The second buffer column 322 may be made of rubber material and may be a cylindrical structure.

[0097] For example, a plurality of second buffer columns 322 may be evenly spaced between the first support seat 100 and the second support seat 200 , so that the elastic support effect of the second support seat 200 on the second support seat 200 is evenly distributed, thereby ensuring the buffering and shock absorbing effect.

[0098] In this embodiment, when the double-walled tube 10 is affected by external factors and vibrates violently, if the first buffer column 321 is greatly deformed due to the vibration and is insufficient to support the first support seat 100, the second buffer column 322 can assume the role of elastically supporting the first support seat 100. Therefore, by providing the second buffer column 322, the elastic buffer part 320 can have a double buffering effect, so as to more effectively absorb and reduce the transmission of external forces such as vibration and impact, and improve the anti-seismic performance of the entire mechanism.

[0099] like Figure 6 As shown, in one embodiment, a plurality of second mounting grooves 220 for mounting the second buffer column 322 are provided on the surface of the second support seat 200 opposite to the first support seat 100. The groove surface of the second mounting groove 220 is designed as an arc surface matching the outer peripheral surface of the second buffer column 322. By fixing the plurality of second buffer columns 322 in the plurality of second mounting grooves 220, the reliable mounting of each second buffer column 322 is ensured.

[0100] Furthermore, a plurality of second grooves 120 for abutting against the outer circumference of the second buffer column 322 are formed on the surfaces opposite to the first support seat 100 and the second support seat 200, and each second mounting groove 220 is opposite to each second groove 120. The groove surface of the second groove 120 is designed as an arc surface matching the outer circumference of the second buffer column 322.

[0101] By providing the second groove 120 , when the second buffer column 322 is fixedly installed in the second installation groove 220 , the outer peripheral surface of the second buffer column 322 away from the second installation groove 220 can contact the second groove 120 , ensuring reliable support of the second buffer column 322 to the first support seat 100 .

[0102] In the embodiment of the present application, the first buffer column 321 and the second buffer column 322 may be made of rubber material, but the present application is not limited thereto. In other embodiments, the first buffer column 321 and the second buffer column 322 may also be made of silicone, elastomeric plastic, etc., depending on the specific situation.

[0103] In the embodiment of the present application, the first buffer column 321 and the second buffer column 322 may be cylindrical structures, but the present application is not limited thereto. In other embodiments, the first buffer column 321 and the second buffer column 322 may also be cylindrical structures with rectangular, elliptical, polygonal, etc. cross-sections, depending on the specific situation.

[0104] When the double-walled pipe fixing device of the embodiment of the present application is used:

[0105] The base 600 can be fixedly installed at a preset position by fixing bolts, and then the height of the upper limit mechanism 400 on the first support seat 100 is adjusted to a suitable position by the adjusting mechanism 500. Then, the double-walled pipe 10 is limited and fixed by the limiting mechanism 400, thereby completing the positioning and installation of the double-walled pipe 10.

[0106] The double-walled pipe fixing device of the embodiment of the present application, through the coordinated arrangement of the first support seat 100, the second support seat 200 and the vibration reduction mechanism 300, enables the first support seat 100 and the second support seat 200 to have a vibration reduction and buffering function, effectively reducing the impact of external shock and vibration on the double-walled pipe 10, which is conducive to maintaining the stability of the pipeline system. Thereby, the service life of the pipeline can be effectively extended, the maintenance cost of the pipeline system can be reduced, and the safety and reliability of the system can be improved.

[0107] Specifically, when the double-walled tube 10 is affected by external factors and vibrates, the vibration will be transmitted to the vibration reduction mechanism 300 between the first support seat 100 and the second support seat 200. The multiple first buffer columns 321 in the vibration reduction mechanism 300 enable the second support seat 200 to elastically support the first support seat 100, and then cooperate with the dampers 310 at the four corners of the second support seat 200 to achieve the effect of buffering and vibration reduction. In addition, the second buffer column 322 is provided to make the elastic buffer part 320 have a double buffering effect, so that the vibration reduction mechanism 300 can more effectively absorb and reduce the transmission of external forces such as vibration and impact, thereby improving the seismic performance of the entire mechanism.
