Description

Technical Field

[0001] This utility model relates to the technical field of pipeline insulation material manufacturing equipment, and proposes an electromagnetic weight reduction device for continuous line spraying and winding insulation pipes. Background Technology

[0002] Currently, in the production of continuous spray-coated and wound insulation pipes, the coating material has not fully cured after passing through the spraying station. Any hard mechanical contact with the pipe (such as rollers or brackets) can easily cause coating scratches, indentations, or uneven compaction of the insulation layer at the contact point, resulting in quality defects. Moreover, there is sliding or rolling friction between the pipe and the supporting rollers during continuous movement. This friction not only generates resistance and increases energy consumption, but also causes slight speed fluctuations or axial movement of the pipe. Correspondingly, instability in the spraying process directly leads to uneven coating thickness and inconsistent winding tightness, seriously damaging the uniformity of product performance. Utility Model Content

[0003] This utility model proposes an electromagnetic weight reduction device for continuous spraying and winding insulation pipes, which solves the technical problems in related technologies, such as high conveying resistance and unstable operation of insulation pipes on continuous spraying and winding production lines due to their own weight, and the large friction of traditional mechanical supports that easily damages the pipe surface and is difficult to quickly adapt to different pipe diameters.

[0004] The technical solution adopted by this utility model is:

[0005] An electromagnetic weight reduction device for continuous line spraying and winding insulation pipes, comprising:

[0006] A support frame having a conveying space in the middle for passing through an insulated pipe;

[0007] A magnetic suction component is movably mounted on the bracket. There is a magnetic suction space between the magnetic suction component and the insulation pipe. The magnetic suction space is located within the conveying space. The magnetic suction space can increase or decrease as the magnetic suction component moves.

[0008] The magnetic suction component is movably mounted on the bracket via a lifting component.

[0009] As a further technical solution, the magnetic attraction component includes:

[0010] An electromagnetic plate is mounted on the lifting assembly;

[0011] Several electromagnetic coils are arranged circumferentially on the electromagnetic plate.

[0012] As a further technical solution, the enhancement component includes:

[0013] A plurality of sliders are provided, and the sliders are slidably disposed on the bracket;

[0014] There are several connecting rods, each of which is hinged at one end to the slider and at the other end to the electromagnetic plate. When the slider slides, the electromagnetic plate is raised or lowered by the connecting rods.

[0015] As a further technical solution, the lifting component also includes:

[0016] The driving component is a plurality of such components, each having one end disposed on the bracket and the other end disposed on the slider.

[0017] As a further technical solution, the bracket is provided with a number of guide grooves, and the number of sliders are slidably disposed in the corresponding guide grooves.

[0018] As a further technical solution, it also includes:

[0019] A plurality of positioning guide rods are provided. Each positioning guide rod has an installation end and a moving end. One end of the installation end is disposed on the bracket, and the moving end is disposed on the electromagnetic plate. The moving direction of the electromagnetic plate is limited by the positioning guide rod.

[0020] As a further technical solution, it also includes:

[0021] A plurality of elastic members are provided, one end of which is disposed on the bracket and the other end of which is disposed on the electromagnetic plate. The elastic members are used to provide a force to move the electromagnetic plate away from the insulation pipe.

[0022] As a further technical solution, it also includes:

[0023] A sensor is mounted on the bracket and is used to detect the speed at which the insulation pipe passes through the conveying space.

[0024] The beneficial effects of adopting the above technical solution are as follows:

[0025] In this invention, existing technologies for thermal insulation pipes on continuous spraying and winding production lines suffer from high conveying resistance and unstable operation due to their own weight. Furthermore, traditional mechanical supports exhibit significant friction, easily damaging the pipe surface and making it difficult to quickly adapt to different pipe diameters. This solution addresses this by installing a bracket above the conveying device, with a conveying space in the middle for the thermal insulation pipe to pass through. A lifting assembly is mounted vertically on the bracket to drive the magnetic suction assembly up and down. The magnetic suction assembly generates an upward magnetic force on the thermal insulation pipe, thus offsetting some of its weight, reducing frictional resistance between the pipe and the conveying mechanism, minimizing physical damage to the surface coating and uncured insulation layer, and improving product yield.

Detailed Implementation

[0031] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. The utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0032] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Reference Figures 1-4 As an embodiment of this utility model, an electromagnetic weight reduction device for continuous line spraying and winding insulation pipe is proposed, which includes:

[0034] Support 1, wherein the support 1 has a conveying space 2 in the middle, the conveying space 2 being used for passing through the heat-insulating pipe;

[0035] The magnetic suction component 4 is movably mounted on the bracket 1. There is a magnetic suction space 5 between the magnetic suction component 4 and the heat preservation pipe. The magnetic suction space 5 is located in the conveying space 2. The magnetic suction space 5 can become larger or smaller as the magnetic suction component 4 moves.

[0036] In this embodiment, for the process of continuously conveying the insulation pipe after spraying but before the foam insulation layer has fully cured to complete the polyethylene outer protective layer winding and subsequent cooling, this solution provides a matching electromagnetic weight reduction device. This device is installed on the corresponding transmission mechanism and includes a support 1, a lifting component 3, and a magnetic suction component 4.

[0037] The support frame 1 has a conveying space 2 in the middle for the insulation pipe to pass through. The lifting component 3 is mounted on the support frame 1 in a lifting manner and is used to drive the magnetic suction component 4 to move up and down. The magnetic suction component 4 can generate an upward magnetic force to act on the insulation pipe, thereby offsetting part of its gravity, reducing the frictional resistance between the insulation pipe and the conveying mechanism, reducing physical damage to the surface coating and uncured insulation layer of the insulation pipe, and improving the product yield.

[0038] Specifically, this solution can change the height of the magnetic suction component 4 by adjusting the lifting component 3, so that the device can be adapted to insulation pipes of different diameters. The size of the magnetic suction space 5, i.e. the distance between the magnetic suction component 4 and the insulation pipe, can be adjusted according to the traveling speed and pipe diameter of the insulation pipe. This allows the magnetic force of the magnetic suction component 4 on the insulation pipe to be adjustable, thereby reducing the friction between the insulation pipe and the conveying device and achieving dynamic weight reduction. This makes the solution highly practical.

[0039] Meanwhile, to further achieve rapid and flexible adjustment of the magnetic attraction force, this design includes several independent electromagnetic coils 7 arranged circumferentially on the electromagnetic plate 6. By adjusting the current flowing through each electromagnetic coil 7 individually or as a whole, its circuit connection can be directly arranged along the support (not shown in the figure), allowing for convenient and precise control of the generated total magnetic attraction force. This enables the device to more accurately adapt to the working conditions of different pipe diameters, materials, or conveying speeds, significantly improving the device's practicality and adaptability.

[0040] Furthermore, in this embodiment, the lifting component 3, through the hinged linkage mechanism formed by the slider 8 and the connecting rod 9, effectively solves the problem of maintaining a stable horizontal posture and achieving reliable transmission during the lifting process of the electromagnetic plate 6. Specifically, the synchronous sliding of the slider 8 on the bracket 1 is converted into the vertical lifting motion of the electromagnetic plate 6 through the corresponding hinged connecting rod 9. Through this multi-point, multi-link transmission method, the load is effectively distributed, avoiding jamming or skew that may occur with single-point drive, ensuring that the electromagnetic plate 6 remains horizontal throughout the lifting process, thereby making the magnetic force act uniformly and vertically on the insulation pipe, further improving the overall practicality.

[0041] To precisely control the final height of the electromagnetic plate 6 and enable it to quickly adapt to the optimal magnetic attraction distance required by insulation pipes of different diameters and speeds, the slider 8 in this solution can be driven by a drive component 10, such as a cylinder. This method further improves the overall efficiency of the solution and has high practical value.

[0042] To ensure that the direction of the magnetic force remains vertical and stable, this solution includes a positioning guide rod 12 on the bracket 1. The positioning guide rod 12, through its rigid guiding function, can effectively resist external interference during daily operation, thereby ensuring the alignment accuracy between the electromagnetic plate 6 and the insulation pipe over a long period of time.

[0043] Meanwhile, to ensure that the electromagnetic plate 6 can automatically and safely reset in the event of power failure or drive failure, and to prevent accidental pressure that could damage the insulation pipe, a tensioning elastic element 15 is provided between the bracket 1 and the electromagnetic plate 6 as an auxiliary mechanism. The tensioning elastic element 15 provides the electromagnetic plate 6 with a force that moves it away from the insulation pipe. In this way, the overall safety and practicality of the solution are further improved.

[0044] To further improve monitoring accuracy and sensitivity, such as Figure 1 As shown, sensor 16 can be installed on the bracket. Sensor 16 is preferably a laser rangefinder and velocimeter, positioned at the end where the insulated pipe enters the conveying space 2. Its circuitry is laid along the bracket (not shown in the figure). When the insulated pipe enters the conveying space 2, sensor 16 detects the pipe diameter and conveying speed in real time and transmits the measurement results to a computer via wired or wireless means. Based on the measurement data, the computer sends control signals to the drive unit 10 to dynamically adjust the distance between the electromagnetic plate 6 and the insulated pipe, thereby keeping the magnetic attraction force within the optimal range. This adjustment helps reduce friction between the insulated pipe and the conveying mechanism, thereby improving the product yield.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
