Description

Technical Field

[0001] The utility model relates to a composite winding pipe with a strengthening function, in particular to a composite winding pipe with a strengthening function, belonging to the technical field of composite winding pipes. Background Technique

[0002] Winding pipes, large-diameter winding pipes, double-wall winding pipes, and hollow winding pipes are a kind of pipe made of high-density polyethylene (HDPE) and formed by winding and welding. Due to their unique forming process, pipes with a diameter of up to 3 meters can be produced, which is difficult to achieve by other production processes.

[0003] The existing composite winding pipes have the following disadvantages: 1. The compressive capacity of the composite winding pipes is slightly weak, and they are prone to deformation and damage under external pressure; 2. The structure of the composite winding pipes is single, and the heat insulation capacity is weak. When the external temperature is relatively high, it is easy to affect the internal liquid transmission. Therefore, improvements are made to the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a composite winding pipe with a strengthening function to solve the above problems. The filling rubber and the inner components of the strengthening frame cooperate to achieve a better impact and compression resistance effect; the heat insulation pads a and b cooperate to achieve a better heat insulation effect.

[0005] The utility model realizes the above purpose through the following technical solutions. A composite winding pipe with a strengthening function includes a pipe body. The pipe body includes an outer layer, a heat insulation pad a, a heat insulation pad b, filling rubber, a strengthening frame, and a winding pipe. The heat insulation pad a is located between the outer layer and the heat insulation pad b. The heat insulation pad b is located outside the strengthening frame. The filling rubber is adhesively bonded to the outside of the strengthening frame. An airbag is arranged inside the strengthening frame. An elastic frame is fixedly connected inside the strengthening frame. The elastic frame is located outside the impact-resistant rod. The strengthening frame is adhesively bonded to the outside of the winding pipe.

[0006] Preferably, the outer layer is located outside the heat insulation pad a, and the heat insulation pad a is adhesively bonded to the heat insulation pad b.

[0007] Preferably, the material of the heat insulation pad a is cross-linked polyethylene foaming material, and the material of the heat insulation pad b is aluminum silicate fiber.

[0008] Preferably, the filling rubber is located between the heat insulation pad b and the strengthening frame, and the material of the filling rubber is polyurethane.

[0009] Preferably, a connecting frame b is fixedly connected to the left side of the strengthening frame, and a connecting frame a is fixedly connected to the right side of the strengthening frame.

[0010] Preferably, the connecting frame a is snap-connected to the connecting frame b, and the airbag is located between the strengthening frame and the elastic frame.

[0011] Preferably, the impact-resistant rod is located between the elastic frame and the strengthening frame, and the material of the impact-resistant rod is high-impact polystyrene.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The filled rubber and the components inside the strengthening frame cooperate to achieve a good impact and compression resistance effect; the pipe body is composed of an outer layer, a thermal insulation pad a, a thermal insulation pad b, filled rubber, a strengthening frame and a winding pipe. The material of the thermal insulation pad a is cross-linked polyethylene foam material, which has high tensile strength, good elasticity and good impact resistance. The strengthening frame is adhesively bonded to the outside of the winding pipe, and filled rubber made of polyurethane is filled between adjacent strengthening frames. The filled rubber has good elasticity and toughness, can absorb the external impact force and achieve a good buffering effect. An airbag is provided between the inside of the strengthening frame and above the strengthening frame and the elastic frame, and the airbag is filled with air to support the strengthening frame. The external pressure can cause the airbag to be squeezed and deformed, and the airbag can play a certain buffering effect. An impact-resistant rod is installed between the elastic frame and the strengthening frame, and the material of the impact-resistant rod is high-impact polystyrene. It adds micron-sized rubber particles and connects the polystyrene and the rubber particles by grafting. When impacted, the stress at the tip of the crack propagation will be released by the relatively soft rubber particles. Therefore, the crack propagation is hindered, and the impact resistance is improved, and it can achieve a good impact resistance effect. Continuous extrusion can cause the impact-resistant rod to be slightly deformed and then the elastic frame to deform. The bottom end of the elastic frame is in contact with the inner wall of the strengthening frame, which can achieve a good supporting effect and prevent it from deforming. The filled rubber, the strengthening frame, the airbag and the impact-resistant rod cooperate to achieve a good compression and anti-deformation effect.

[0014] The thermal insulation pad a and the thermal insulation pad b cooperate to achieve a good heat insulation effect; the thermal insulation pad a made of cross-linked polyethylene foam material is adhesively bonded to the inside of the outer layer, which has a low thermal conductivity and a good heat insulation and heat preservation effect. The material of the thermal insulation pad b adhesively bonded to the thermal insulation pad a is aluminum silicate fiber, which has a low thermal conductivity, a small heat capacity and excellent heat insulation characteristics, and a good heat insulation and heat preservation effect. A large amount of air is filled in the airbag provided inside the strengthening frame, which can play a certain heat insulation effect, and a good heat insulation effect can be achieved through the cooperation of the thermal insulation pad a and the thermal insulation pad b.
