Description

TECHNICAL FIELD

[0001] The utility model relates to a heat insulation pipe processing technical field, concretely relates to a kind of auxiliary coating mechanism of heat insulation pipe heat insulation material. BACKGROUND

[0002] Heat insulation pipe is one of important materials for exploitation and transportation of petroleum, geothermal etc., and heat insulation pipe inner tube is made by coating heat insulation material on the outer part of pipe material after pipe material production, so the secondary packaging of heat insulation material on pipe material surface makes heat insulation material reliably coated on the outer wall of pipe material, which plays an important role in the whole production process of heat insulation pipe.In the prior art, the commonly used way for the packaging of heat insulation pipe surface material is to suspend the whole pipe by lifting both ends of the pipe, then drive the pipe to rotate by the lifting device at both ends, and then multiple winding objects move along the axial direction of the pipe to wrap the winding objects on the outer wall of the steel pipe.The existing packaging method has the following defects:

[0003] Because the pipe is long (usually about 10 meters), the middle part of the pipe will bend due to its own weight after being lifted at both ends. Since the heat insulation material is poor in toughness and easy to break, the heat insulation material may loosen and break after the deformation of the pipe is restored when the coating of the heat insulation material is completed. Therefore, it is difficult to control the tightness of the heat insulation material when it is arranged, which makes it difficult for the heat insulation material to adhere to the surface of the pipe and greatly reduces the heat insulation effect. UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide an auxiliary coating mechanism for heat insulation material on the surface of a heat insulation pipe, which changes the traditional pipe coating action and gradually coats the heat insulation material on the surface of the pipe using a folding roller set during the axial movement of the pipe, thereby improving the adhesion of the heat insulation material to the surface of the pipe.

[0005] The utility model solves the technical problem by adopting the following technical scheme: the auxiliary coating mechanism for heat insulation material on the inner tube of a heat insulation pipe comprises a folding roller set, a plurality of guide rollers are arranged in the folding roller set for gradually coating the heat insulation material on the surface of the pipe, the plurality of guide rollers are arranged in sequence on the path of the axial movement of the pipe, the heat insulation material is located between the guide rollers and the pipe, and moves synchronously with the axial movement of the pipe.

[0006] Preferably, the folding roller set comprises a pre-bending roller set and a forming roller set arranged in sequence along the moving direction of the pipe.

[0007] Preferably, the pre-bending roller set comprises a pre-bending side roller and a pre-bending bottom roller arranged in sequence along the moving direction of the pipe, and the forming roller set comprises a forming side roller and a forming bottom roller arranged in sequence along the moving direction of the pipe.

[0008] Preferably, in the gathering roller group, a horizontal supporting roller arranged at the front end of the pre-bending roller group is further included, and the horizontal supporting roller is arranged at a distance from the pipe.

[0009] Preferably, the pre-bending side roller and the forming side roller are arranged at least on one side of the pipe.

[0010] Preferably, the pre-bending bottom roller and the forming bottom roller are horizontally arranged at the lower part of the pipe, and the pre-bending side roller and the forming side roller are symmetrically arranged at the two sides of the pipe.

[0011] Preferably, the pre-bending side roller is arranged at an angle at the side of the pipe.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] By means of the auxiliary coating mechanism for the heat insulation pipe heat insulation material, the action mode of traditional pipe coating is changed, the heat insulation material is gradually coated on the pipe surface in the process of axial movement of the gathering roller group, and the adhesion of the heat insulation material and the pipe surface is improved.

[0014] By means of the auxiliary coating mechanism for the heat insulation pipe heat insulation material, the action mode of the pipe itself is changed when the heat insulation material is arranged on the pipe surface in the prior art, and the heat insulation material is gradually coated on the pipe surface in the process of axial movement of the gathering roller group, so that subsequent bandaging is facilitated.

[0015] Since the pipe does not need to be lifted at both ends and suspended for arranging the heat insulation material, the problems of loosening and breaking of the heat insulation material due to deformation of the pipe itself in the traditional packaging mode are avoided.

[0016] In the auxiliary coating mechanism for the heat insulation pipe heat insulation material, the multiple guide rollers in the gathering roller group gradually coat the heat insulation material on the pipe surface in the process of axial movement of the heat insulation material along with the pipe, and the automation degree is improved.

[0030] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-12 The present invention will be further described below.

[0031] Example 1:

[0032] like Figures 1-2As shown, an auxiliary coating mechanism for thermal insulation material in a heat-insulating pipe includes a gathering roller group. The gathering roller group comprises multiple rollers arranged sequentially along the traveling direction of the pipe 6: a horizontal support roller 5, a pre-bending bottom roller 4, a pre-bending side roller 3, a forming bottom roller 2, and a forming side roller 1. The horizontal support roller 5, pre-bending bottom roller 4, pre-bending side roller 3, forming bottom roller 2, and forming side roller 1 are all vertically arranged via corresponding roller supports 8. The pre-bending bottom roller 4, pre-bending side roller 3, forming bottom roller 2, and forming side roller 1 are all U-shaped support rollers with a "U"-shaped groove in the middle. The horizontal support roller 5 is a cylindrical roller. The axial movement of the pipe 6 can be achieved using a conveying mechanism known in the art, such as the technical solution described in Chinese Utility Model Patent Application No. 202420737813.8, filed on April 10, 2024, entitled "A Welded Pipe Conveying Mechanism," the specific implementation of which will not be repeated here.

[0033] A heat insulation material support 7 is provided on the side of the gathering roller assembly. Rollers are rotatably mounted on the heat insulation material support 7, and heat insulation material 9 is wound onto the rollers. The heat insulation material 9 is released from the winding rollers and stretched into the gathering roller assembly. It advances with the tube 6 within the gathering roller assembly. As it advances with the tube 6, the heat insulation material 9 gradually adheres to and covers the outside of the tube 6 under the guiding and gathering action of the gathering roller assembly. The heat insulation material 9 completes the covering of the tube 6 before entering the wrapping device.

[0034] A wrapping device is provided at the outlet of the gathering roller assembly. After passing through the wrapping device, the tube 6 is wrapped by the wrapping tape released from the wrapping device, and the heat insulation material 9 is packaged and fixed on the surface of the tube 6 at the same time. The wrapping device can also be implemented using a conveying mechanism known in the art, such as the technical solution described in Chinese Utility Model Patent Application No. 202410719848.3, filed on June 4, 2024, entitled "A Highly Stable Tube Packaging Machine". The specific implementation method will not be described in detail here.

[0035] like Figures 3-7 After being released from the insulation material support 7, the insulation material 9 first extends to the horizontal roller 5, which is located at the bottom of the pipe 6 and spaced apart from it. The horizontal roller 5 adjusts the insulation material 9 to a horizontal state. After passing the horizontal roller 5, the insulation material 9 extends to the pre-bending bottom roller 4, which is also located at the bottom of the pipe 6 and spaced apart from it. The insulation material 9 forms an arc-shaped structure at the bottom under the action of the groove on the surface of the pre-bending bottom roller 4.

[0036] After passing through the pre-bending bottom roller 4, the thermal insulation material 9 extends to the pre-bending side roller 3. There are two pre-bending side rollers 3, which are symmetrically located on both sides of the pipe 6 and are inclined. The thermal insulation material 9 passes through the gap between the pre-bending side roller 3 and the pipe 6, and simultaneously contacts both the pre-bending side roller 3 and the pipe 6. The pre-bending side roller 3 further adheres the thermal insulation material 9 to the pipe 6.

[0037] After passing through the pre-bending side roller 3, the heat insulation material 9 extends to the forming bottom roller 2, which is located at the bottom of the tube 6. The heat insulation material 9 passes through the gap between the forming bottom roller 2 and the tube 6, simultaneously contacting both the forming bottom roller 2 and the tube 6. The two ends of the grooves on the surface of the forming bottom roller 2 extend to the axis of the tube 6. When the heat insulation material 9 passes through the forming bottom roller 2, the lower half of the tube 6 is covered by the heat insulation material 9. After passing through the forming bottom roller 2, the heat insulation material 9 extends to the forming side rollers 1. Two forming side rollers 1 are provided, horizontally symmetrically located on both sides of the tube 6. The heat insulation material 9 passes through the gap between the forming side rollers 1 and the tube 6, simultaneously contacting both the forming side rollers 1 and the tube 6. The grooves on the surfaces of the two forming side rollers 1 are joined together and located on both sides of the tube 6. Under the action of the two forming side rollers 1, the heat insulation material 9 completely covers the outside of the tube 6.

[0038] As the heat insulation material 9 passes sequentially through the horizontal idler roller 5, the pre-bending bottom roller 4, the pre-bending side roller 3, the forming bottom roller 2, and the forming side roller 1, its deformation trend is as follows: Figure 8 As shown. After passing through the forming side roller 1, the heat insulation material 9 enters the wrapping device. Under the action of the wrapping device, the wrapping tape is wrapped around the surface of the pipe 6, and at the same time, the heat insulation material 9 is fixed to the surface of the pipe 6.

[0039] The specific working process and working principle are as follows:

[0040] After the rolled insulation material 9 and the insulation material support 7 are installed, the operator manually stretches the insulation material 9 so that the front end of the insulation material 9 is flush with the end of the pipe 6 near the wrapping device. After passing through the gathering roller group, the insulation material 9 is in contact with at least the forming side roller 1, the forming bottom roller 2, and the pre-bending side roller 3 in the gathering roller group.

[0041] When the pipe 6 moves axially, since the heat insulation material 9 is in contact with at least the forming side roller 1, forming bottom roller 2 and pre-bending side roller 3 in the gathering roller group, the pipe 6 will squeeze the heat insulation material 9 and form a sufficiently large frictional force between the pipe 6 and the heat insulation material 9 and between the heat insulation material 9 and the rollers (forming side roller 1, forming bottom roller 2 and pre-bending side roller 3) in the gathering roller group, so that the pipe 6 drives the heat insulation material 9 to move forward synchronously while moving forward axially.

[0042] As the pipe 6 moves forward, the thermal insulation material 9 gradually covers the surface of the pipe 6 under the action of the rollers in the take-up roller group. Then, the wrapping device set on the output side of the take-up roller group wraps the wrapping tape around the surface of the pipe 6, and at the same time fixes the thermal insulation material 9 to the surface of the pipe 6.

[0043] Example 2:

[0044] The difference between this embodiment and Embodiment 1 lies in the arrangement of the forming side roller 1 and the pre-bending side roller 3 in the gathering roller assembly. For example... Figures 9-11 As shown, in this embodiment, only one forming side roller 1 and one pre-bending side roller 3 are provided. That is, after the heat insulation material 9 passes through the gathering roller group, the gathering roller group only covers one side of the pipe 6 with the heat insulation material 9.

[0045] In the subsequent winding process, the winding method needs to be set: the wrapping tape is wound from the side that is not fully covered to the side that is fully covered. Therefore, during the winding process, the wrapping tape simultaneously covers the side of the insulation material 9 that is not yet covered, and then the entire pipe 6 is wrapped and packaged. Figure 12 As shown.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
