Abstract
Description
Technical Field
[0001] The present application relates to the field of pipelines, and in particular to a PERT insulation pipe support with energy absorption effect. Background Art
[0002] The PERT insulated pipe is connected with a tee at the confluence, and the PERT insulated pipe is inserted into the tee and fixed by heat fusion welding. After the PERT insulated pipe and the tee are heat fusion welded, since the PERT insulated pipe is located inside the tee, when testing the welding effect, it is necessary to cut open the tee and the PERT insulated pipe for destructive testing, so random inspection is usually used to test the welding results.
[0003] When there is a PERT tube that is not welded securely, the medium flowing in the PERT tube will cause the PERT tube to expand and extend, and the PERT tube may expand out of the tee, causing the welding position between the PERT tube and the tee to crack, and the connection between the PERT tube and the tee to be unstable. Utility Model Content
[0004] In order to make the connection between the PERT pipe and the tee pipe more stable, the present application provides a PERT insulation pipe bracket with energy absorption effect.
[0005] This application provides a PERT insulation pipe support with energy absorption effect, which adopts the following technical solutions:
[0006] A PERT insulation pipe support with an energy-absorbing effect is provided at the connection position between the pipe body and the tee pipe, and includes a mounting plate provided below the pipe body, a motor installed on the ground, a lead screw penetrating the mounting plate and threadedly connected to the mounting plate connected to the output shaft of the motor, and a guide rod penetrating the mounting plate and slidably plugged into the mounting plate further connected to the ground;
[0007] A pull ring located above the mounting plate is fixed to both the pipe body and the tee pipe, and a hinged rod is hinged to the pull ring, and the lower ends of the two corresponding hinged rods are hinged to each other, and the hinged rods are hinged to the mounting plate, and the two corresponding hinged rods are gradually inclined away from each other from bottom to top;
[0008] The connection between the pipeline body and the tee pipe is also covered with a protective cover with a door.
[0009] By adopting the above technical solution, when medium flows in the pipeline body, the motor is controlled to work, and the motor drives the lead screw to rotate. At the same time, the guide rod guides the mounting plate, so that the mounting plate drives the lower end of the hinged rod to move downward, and at the same time, the upper end of the hinged rod also moves downward and toward each other. The hinged rod limits the corresponding pull ring, so that the pull ring limits the pipeline body and the tee, reducing the situation where the pipeline body is separated from the tee due to expansion, thereby making the connection between the PERT tube and the tee more stable; when the medium in the pipeline body stops flowing, the motor is controlled to work, so that the lead screw rotates in the opposite direction, and the mounting plate drives the lower end of the hinged rod to move upward. At the same time, the hinged rod rotates and resets, thereby driving the pull ring to reset, and the force applied to the pipeline body and the tee is gradually eliminated.
[0010] Optionally, an arc-shaped supporting plate is provided between the pipe body and the mounting plate, a support rod is connected to the supporting plate, the lower end of the support rod is fixed to the ground, and the pipe body and the tee pipe are overlapped on the supporting plate.
[0011] By adopting the above technical solution, the support plate wraps the pipe body, thereby reducing the deviation of the pipe body during vibration.
[0012] Optionally, both side edges of the support plate are integrally formed with convex plates, and both side edges of the pull ring are also integrally formed with support plates, and the support plates are overlapped on the convex plates.
[0013] By adopting the above technical solution, the convex plate cooperates with the support plate to support the pull ring, thereby reducing the deformation of the pull ring when the hinged rod pulls the pull ring to move.
[0014] Optionally, the hinge rod is detachably connected to the mounting plate.
[0015] By adopting the above technical solution, when the lead screw and the mounting plate need to be replaced, the hinged rod can be separated from the mounting plate, which makes it convenient for the operator to replace the mounting plate and the lead screw.
[0016] Optionally, a plug-in block is connected to the hinge shaft at one end of the two hinged rods hinged to each other, and a plug-in slot adapted to the plug-in block is provided on the mounting plate, and the plug-in block is plugged into the corresponding plug-in slot.
[0017] By adopting the above technical solution, when replacing the lead screw and the mounting plate, the door of the protective cover is opened, the lead screw is cut, and the mounting plate is pulled away from the plug-in block until the plug-in block is disengaged from the plug-in slot. At this time, the operator takes a new lead screw and mounting plate, aligns the plug-in slot with the plug-in block, and then pushes the mounting plate until the plug-in block is inserted into the plug-in slot. Finally, the lead screw is fixed to the output shaft of the motor, thereby completing the replacement of the mounting plate and the lead screw.
[0018] Optionally, the plug-in block and the plug-in slot are interference fit.
[0019] By adopting the above technical solution, the hinged rod can better cooperate with the top plate, reducing the situation where the plug-in block is separated from the plug-in slot, thereby reducing the situation where the hinged rod is separated from the top plate.
[0020] Optionally, a hardened plate is provided on the ground at a position corresponding to the protective cover, and the protective cover and the hardened plate are fixed by bolts.
[0021] By adopting the above technical solution, the occurrence of the protective cover sinking is reduced.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up a motor, a lead screw, a guide rod, a pull ring and a hinged rod, the connection between the PERT tube and the tee pipe is made more stable;
[0024] 2. By providing a supporting plate, a convex plate and a supporting plate, the pull ring can be supported, reducing the possibility of deformation of the pull ring;
[0025] 3. By setting the plug-in block and the plug-in slot, the operator can more conveniently replace the mounting plate and the lead screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The embodiment of the present application discloses a PERT insulation pipe support with energy absorption effect. Figure 1 and Figure 2, arranged on the pipe body 1 and the tee pipe 11, including a protective cover 2 arranged at the connection position of the pipe body 1 and the tee pipe 11, the protective cover 2 has a door, and the soil below the protective cover 2 is hardened to form a hardened plate 21, and the protective cover 2 and the hardened plate 21 are fixed by bolts; the hardened plate 21 reduces the occurrence of the protective cover 2 being embedded in the soil by force.
[0032] A motor 3 is fixedly connected to the inner bottom wall of the protective cover 2, with the output shaft of the motor 3 facing upward, and a coaxial lead screw 31 is fixedly connected to the top of the output shaft of the motor 3. A guide rod 32 is provided on one side of the motor 3 and is vertically fixedly connected to the inner bottom wall of the protective cover 2; a mounting plate 33 corresponding to the pipe body 1 is threadedly connected to the lead screw 31, and the mounting plate 33 is located directly below the pipe body 1 and the tee pipe 11, and the guide rod 32 passes through the mounting plate 33 and is slidably plugged into the mounting plate 33.
[0033] An arc-shaped support plate 4 is provided above the mounting plate 33. The middle part of the support plate 4 is bent downward, and the support plate 4 is coaxial with the corresponding pipe body 1. The support plate 4 is located directly below the pipe body 1 and the tee pipe 11; the lower surface of the support plate 4 is also fixedly connected to a support rod 41, and the mounting plate 33 is located on one side of the support rod 41. The lower end of the support rod 41 is fixed to the inner bottom wall of the protective cover 2, and the support rod 41 supports the support plate 4.
[0034] The pipe body 1 and the tee pipe 11 are fixedly connected at one end close to each other with an arc-shaped pull ring 5, the pull ring 5 is coaxial with the pipe body 1, and the pull ring 5 is located above the support plate 4; the tops of both sides of the support plate 4 are integrally formed with convex plates 42, and the length direction of the convex plates 42 is set along the length direction of the pipe body 1, and the bottoms of both sides of the pull ring 5 are also integrally formed with support plates 51, the support plates 51 are located above the convex plates 42, and the convex plates 42 support the support plates 51, thereby reducing the occurrence of deformation of the pull ring 5 under force.
[0035] Reference Figure 2 and Figure 3 A hinged rod 6 is hinged on the convex plate 42. The lower ends of the two hinged rods 6 located on the same side of the pipe body 1 are hinged to each other. A plug-in block 7 is fixedly connected to the hinge axis of the two hinged rods 6. A plug-in groove 331 adapted to the plug-in block 7 is opened on the side wall corresponding to the mounting plate 33 and the plug-in block 7. The plug-in block 7 is plugged into the corresponding plug-in groove 331, and the plug-in block 7 is interference fit with the plug-in groove 331; the plug-in block 7 cooperates with the plug-in groove 331 to make the hinged rod 6 detachable and connected to the top plate.
[0036] When the medium in the pipe body 1 flows, the control motor 3 works to rotate the lead screw 31, and at the same time the guide rod 32 guides the mounting plate 33, so that the mounting plate 33 drives the plug-in block 7 and the corresponding end of the hinged rod 6 to move downward, thereby rotating the hinged rod 6, and the upper ends of the corresponding two hinged rods 6 move toward each other, and at the same time the hinged rod 6 drives the corresponding pull ring 5 and the pipe body 1 to move; since the pull ring 5 is not sufficient to pull the pipe body 1 to move, the pull ring 5 only provides force for the two pipe bodies 1, which reduces the situation where the pipe body 1 is separated from the tee pipe 11 due to expansion, and makes the connection between the PERT tube and the tee pipe 11 more stable.
[0037] When the medium in the pipe body 1 stops flowing, the motor 3 is controlled to work, so that the screw 31 rotates in the opposite direction, and the mounting plate 33 drives the plug-in block 7 and the lower end of the hinged rod 6 to move upward and reset, thereby rotating and resetting the hinged rod 6. At the same time, the hinged rod 6 drives the pull ring 5 to reset, so that the force applied to the pipe body 1 is gradually eliminated; when the screw 31 and the mounting plate 33 need to be replaced, the operator opens the door on the protective cover 2, cuts the screw 31, and then pulls the screw 31 and the mounting plate 33 to disengage the plug-in block 7 from the plug-in slot 331, and then takes a new screw 31 and the mounting plate 33, and aligns the plug-in slot 331 with the plug-in block 7, and then moves the mounting plate 33 to insert the plug-in block 7 into the plug-in slot 331, and finally fixes the screw 31 on the output shaft of the motor 3, which is convenient for the operator to replace the screw 31 and the mounting plate 33.
[0038] The implementation principle of a PERT insulated pipe bracket with energy absorption effect in an embodiment of the present application is: when the medium in the pipe body 1 flows, the motor 3 is started to move the mounting plate 33 downward, and the mounting plate 33 drives the pull ring 5 to move through the hinged rod 6, applying force to the connection position between the pipe body 1 and the tee pipe 11; when the medium in the pipe body 1 stops flowing, the motor 3 is controlled to work to move the mounting plate 33 upward, and the mounting plate 33 drives the pull ring 5 to reset through the hinged rod 6, and at the same time, the force applied to the pipe body 1 is eliminated.
[0039] When the screw 31 and the mounting plate 33 need to be replaced, open the door of the protective cover 2, cut the screw 31, and pull the mounting plate 33 to separate the plug-in block 7 from the top plate; take a new screw 31 and mounting plate 33, insert the plug-in block 7 into the plug-in slot 331, and finally fix the screw 31 to the output shaft of the motor 3.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
