Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation pipe technology, and more specifically, it relates to a polyurethane thermal insulation pipe with a pipe support. Background Technology

[0002] Polyurethane insulated pipe is a high-efficiency and energy-saving prefabricated insulated pipe that is widely used in centralized heating, cooling, petrochemical, municipal engineering and other fields. Polyurethane insulated pipe with pipe support has a pipe support structure installed on the outside of the polyurethane insulated pipe to effectively support and fix the pipe, ensuring the stability and safety of the polyurethane insulated pipe during operation.

[0003] According to application number CN201920146892.4, a polyurethane insulated pipe is disclosed, relating to the field of petroleum equipment. This polyurethane insulated pipe comprises, from the inside out, a working pipe, an aluminum silicate layer, a drag-reducing layer, a microporous calcium silicate layer, a heat insulation layer, an aluminum foil reflective layer, a polyurethane insulation layer, an outer casing, and an outer anti-corrosion layer. During connection, the working pipe of adjacent insulated pipes can be inserted into the outer casing, and then the two fitted outer casings are sealed together by welding. Because several fastening bands are provided between the working pipe and the outer casing, the polyurethane insulated pipe has a stable structure and is not easily deformed or leaked during use.

[0004] Based on the above, when existing polyurethane insulated pipes with pipe supports are used and the pipe support is installed in the wrong position and needs to be moved, it is usually necessary to disassemble the pipe support, move it to the appropriate position, and then reinstall it. This operation is cumbersome and affects work efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a polyurethane insulation pipe with a pipe support. This solves the problem that when the pipe support is installed incorrectly and needs to be moved, it is usually necessary to disassemble the pipe support, move it to the correct position, and then reinstall it. This process is cumbersome and affects work efficiency.

[0006] The purpose and function of this utility model of a polyurethane insulation pipe with a pipe support are achieved by the following specific technical means:

[0007] A polyurethane insulated pipe with a pipe support includes a base, a fixed upright plate, a sliding upright plate, a fixed pipe support, a hinged pipe support, an insulation sleeve, an insulation inner pipe, an adjustment mechanism, and a fastening mechanism. Two fixed upright plates are provided, each fixedly connected to the upper surface of the base.

The fixed pipe support is fixedly connected to the upper end of the two sliding upright plates. The hinged pipe support is hinged to the upper end of the fixed pipe support. The insulation sleeve is disposed on the upper end of the fixed pipe support. The insulation inner pipe is fixedly connected to the inner side of the insulation sleeve. The adjustment mechanism is disposed on the inner side of the base. The fastening mechanism is disposed on the upper end of the fixed pipe support.

[0008] Furthermore, the adjustment mechanism includes: a connecting bevel gear, a driving bevel gear, and a connecting operating rod; the connecting bevel gear is rotatably connected to the inner side of the base; the driving bevel gear is rotatably connected to the inner side of the base, and the driving bevel gear meshes with the connecting bevel gear; the connecting operating rod is fixedly connected to the outer side of the driving bevel gear, and the connecting operating rod is rotatably connected to the inner side of the base.

[0009] Furthermore, the adjustment mechanism also includes: a fixed threaded rod and a connecting threaded sleeve; the fixed threaded rod is fixedly connected to the lower end face of the fixed tube support; the connecting threaded sleeve is fixedly connected to the upper end face of the connecting bevel gear, the connecting threaded sleeve is rotatably connected to the inner side of the upper end of the base, and the connecting threaded sleeve is threadedly connected to the fixed threaded rod.

[0010] Furthermore, the fastening mechanism includes: fixed washers and connecting balls; there are two fixed washers, which are respectively fixedly connected to the inner sides of the fixed tube support and the hinged tube support; there are two sets of connecting balls, which are respectively rotatably connected to the inner sides of the two fixed washers.

[0011] Furthermore, the fastening mechanism also includes: a fixed bracket, a connecting groove, a hinge rod, and fasteners; two fixed brackets are provided, both of which are fixedly connected to the outside of the fixed pipe support; two connecting grooves are provided, both of which are opened on the outside of the hinge pipe support; two hinge rods are provided, each of which is hinged to the inside of the two fixed brackets; and two fasteners are provided, each of which is threadedly connected to the outside of the two hinge rods.

[0012] Furthermore, the fastening mechanism also includes: a threaded fixing sleeve, a fastening threaded component, and a fastening block; the threaded fixing sleeve is fixedly connected to the upper end face of the hinge tube support; the fastening threaded component is threadedly connected to the inner side of the threaded fixing sleeve; the fastening block is slidably connected to the inner side of the upper fixing washer ring, and the fastening block is threadedly connected to the fastening threaded component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves height adjustment of the insulation pipe through an adjustment mechanism. When the operator rotates the connecting operating rod, the rod drives the drive bevel gear to rotate synchronously. Since the drive bevel gear meshes with the connecting bevel gear, this rotational motion is transmitted to the connecting threaded sleeve, causing it to rotate. During rotation, the connecting threaded sleeve, through its threaded engagement with the fixed threaded rod, can drive the fixed pipe support to move vertically. This linkage mechanism allows the installation height of the insulation sleeve and the inner insulation pipe to be adjusted according to actual working conditions, enhancing the environmental adaptability of the entire pipeline system. The fastening mechanism enables the installation and adjustment of the fixed pipe support and the hinged pipe support. During installation, the inner insulation pipe with the insulation sleeve already fitted is first placed inside the fixed pipe support, and then the fastening mechanism is closed. The pipe support is hinged, and the hinge rod is accurately inserted into the connecting groove. By tightening the fastener, the pipe support and the hinged pipe support can be locked together. The operator then rotates the fastening threaded part, which drives the fastening block downward under the cooperation of the threaded fixing sleeve. At this time, the fastening block will be inserted into the heat insulation pipe sleeve, effectively preventing pipe displacement. When it is necessary to adjust the position of the pipe support, simply rotate the fastening threaded part in the opposite direction to remove the fastening block, and the position adjustment can be easily completed. This simplifies the operation process and greatly improves work efficiency while ensuring installation accuracy. Through the above mechanism, not only is the installation height of the heat insulation pipe infinitely adjustable to meet the needs of different working conditions, but the installation and adjustment process of the pipe support is also optimized. This innovative design not only improves the adaptability and reliability of the pipeline system, but also effectively reduces the labor intensity of construction personnel.
