Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to a high-strength thermal insulation pipe reinforcement device. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used for thermal insulation of pipelines in petroleum, chemical industry, aerospace, hot spring, military, central heating, central air conditioning, municipal and other fields. The insulated pipe has a polyurethane rigid foam insulation layer tightly bonded to the outer skin of the steel pipe, which isolates the infiltration of air and water and can play a good anti-corrosion role.

[0003] As we all know, the insulation pipe consists of an inner pipe, an outer pipe and an insulation layer, wherein the insulation layer is composed of aluminum silicate, a drag reduction layer, microporous calcium silicate, a heat insulation layer, a stainless steel fastening steel belt, an aluminum foil reflective layer, a polyurethane insulation layer, an outer jacket steel pipe, and an outer anti-corrosion layer. Some gases or liquids are transported through the inner pipe, and then the gas or liquid inside the inner pipe is insulated by the insulation layer to prevent heat dissipation. However, the outer pipe is used to protect the insulation layer. When transporting the insulation pipe, it is necessary to use cranes, forklifts and other transport tools for transport. During the transportation process, since the insulation pipe is round, it is easy to cause the insulation pipe to separate from the transport device, which will cause An accident may cause the insulation pipe to collide with external force, which may easily cause external objects to impact the outer pipe. Since the insulation layer is mostly a soft structure, it is difficult to form a supporting effect on the outer pipe. When the outer pipe is impacted from the outside, the inside cannot support the outer pipe, which may easily cause the outer pipe to deform under the action of the impact force, causing the outer pipe to dent or collapse. When the outer pipe is dented, the outer pipe squeezes the internal space, thereby reducing the distance between the inner and outer pipes, causing the internal insulation layer to be squeezed, causing the insulation layer to be ruptured or deformed, thereby causing damage to the insulation pipe.

[0004] In view of the above problems, a high-strength thermal insulation pipe reinforcement device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] See also Figure 1-5 The utility model provides a technical solution: a high-strength thermal insulation pipe reinforcement device, including an inner tube 2, an insulation layer 3 is arranged on the outside of the inner tube 2, an outer tube 1 is slidably sleeved on the surface of the insulation layer 3, a fixing ring 9 is fixedly sleeved on one end of the inner tube 2, an insertion rod 10 is fixedly installed on the side of the fixing ring 9 close to the outer tube 1, and a socket matching the insertion rod 10 is opened on the side of the outer tube 1 close to the fixing ring 9.

[0026] The outer tube 1 is pushed to move on the surface of the insulation layer 3, and when the outer tube 1 contacts the fixing ring 9, the insertion rod 10 is inserted into the insertion hole on the outer tube 1, thereby pre-fixing the outer tube 1, facilitating the later installation of the outer tube 1 and improving the convenience of device installation.

[0027] Two fixing blocks 11 are fixedly installed on the surface of the inner tube 2 , and the insides of the two fixing blocks 11 are rotatably connected with a threaded rod 4 , and one end of the threaded rod 4 rotates through the insulation layer 3 and extends to the outside of the insulation layer 3 .

[0028] The setting of the fixing block 11 facilitates the fixing block 11 to support the threaded rod 4 , which is convenient for later installation and fixing.

[0029] The threads on the surface of the threaded rod 4 are arranged in opposite directions.

[0030] Two threaded sleeves 12 are threadedly connected on the surface of the threaded rod 4, and the two threaded sleeves 12 are respectively located at the opposite threads on the surface of the threaded rod 4. A connecting seat 13 is fixedly installed on the surface of the two threaded sleeves 12. The insides of the two connecting seats 13 are rotatably connected with support shafts 15, and the two support shafts 15 are rotatably connected with connecting rods 8. The two connecting rods 8 are rotatably connected inside the two connecting seats 13 respectively, and a second connecting seat 7 is rotatably connected on the opposite ends of the two connecting rods 8. A support plate 6 is fixedly installed on the end of the second connecting seat 7 away from the connecting rod 8. A groove 5 is opened on the inner wall of the outer tube 1, and the support plate 6 is slidably connected inside the groove 5. A limiting guide rod 16 is fixedly installed between the two fixed blocks 11, and the surfaces of the two limiting guide rods 16 are respectively slidably connected to the insides of the two threaded sleeves 12.

[0031] When the threaded rod 4 is rotated, the two threaded sleeves 12 are restricted by the limiting guide rod 16 and cannot rotate, so that the two threaded sleeves 12 move relatively on the surface of the limiting guide rod 16 and the surface of the threaded rod 4, so that the two threaded sleeves 12 drive the two connecting seats 13 to move, so that the two connecting seats 13 squeeze the opposite ends of the two connecting rods 8, so that the angles of the two connecting rods 8 change, so that the two connecting rods 8 drive the two supporting shafts 15 to rotate respectively inside the two connecting seats 13, so that the second connecting seat 7 moves, and then pushes the support plate 6 to move, so that the support plate 6 enters the inside of the groove 5, so as to facilitate the support of the outer tube 1, prevent the outer tube 1 from being sunken when it is squeezed from the outside, improve the strength of the insulation pipe, prevent damage, and maximize the bearing capacity of the insulation pipe. At the same time, it is convenient to fix the outer tube 1 to prevent the outer tube 1 from sliding, so as to ensure the convenience of installation of the insulation pipe.

[0032] A fixing protrusion 14 is fixedly installed on one side of the support plate 6 close to the groove 5. A fixing groove 17 is opened inside the groove 5. The fixing protrusion 14 is slidably connected inside the fixing groove 17. The fixing protrusion 14 and the fixing groove 17 are both triangular in shape.

[0033] When the support plate 6 slides toward the inside of the groove 5, the fixing protrusion 14 will enter the inside of the fixing groove 17, thereby increasing the friction between the support plate 6 and the groove 5, improving the fixing effect of the support plate 6 on the outer tube 1, preventing shaking, and ensuring the stability of the device.

[0034] Working principle:

[0035] When the threaded rod 4 is rotated, the two threaded sleeves 12 are restricted by the limiting guide rod 16 and cannot rotate, so that the two threaded sleeves 12 move relatively on the surface of the limiting guide rod 16 and the surface of the threaded rod 4, and then the two threaded sleeves 12 drive the two connecting seats 13 to move, and then the two connecting seats 13 squeeze the opposite ends of the two connecting rods 8, so that the angles of the two connecting rods 8 change, and then the two connecting rods 8 drive the two support shafts 15 to rotate respectively inside the two connecting seats 13, so that the second connecting seat 7 moves, and then pushes the support plate 6 to move, so that the support plate 6 enters the inside of the groove 5, so as to facilitate the support of the outer tube 1.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
