[0029] Example 1

[0030] Reference Figure 1-Figure 5 The present embodiment provides a wire pulling guide device, including a winding mechanism 100 and a guide mechanism 200. The winding mechanism 100 is used to wind the pipeline 500. The guide mechanism 200 includes a guide frame 210. The guide frame 210 is used for the pipeline 500 to pass through. The side of the guide frame 210 close to the winding mechanism 100 is the wire inlet side, and the side of the guide frame 210 away from the winding mechanism 100 is the wire outlet side. At least two horizontal rollers 220 are arranged in an upper and lower staggered manner on the guide frame 210. At least one horizontal roller 220 is arranged on the wire inlet side and close to the inner top of the guide frame 210, and at least one horizontal roller 220 is arranged on the wire outlet side and close to the inner bottom of the guide frame 210.

[0031] In this embodiment, when the pipeline 500 on the winding mechanism 100 is retracted and passed through the guide frame 210, since the two horizontal rollers 220 can form a structural form of staggered arrangement up and down, when the pipeline 500 passes between the two horizontal rollers 220, the bottom protruding surface of the horizontal roller 220 near the top of the guide frame 210 first contacts the upper surface of the pipeline 500, and at the same time, the top protruding surface of the horizontal roller 220 near the bottom of the guide frame 210 contacts the lower surface of the pipeline 500, so that the pipeline 500 is always in contact with the horizontal roller 220, thereby effectively reducing the risk of scratching and wearing the edge of the guide frame 210 when the pipeline 500 is drooping and retracted, thereby increasing the service life of the pipeline 500. In addition, the horizontal roller 220 located near the top of the guide frame 210 can press the pipeline 500 more tightly when winding the line to prevent the pipeline 500 from loosening.

[0032] It should be noted that here, two upper and lower horizontal rollers 220 are provided to meet the use requirements. In some special use scenarios, more than two can be provided. For example, three horizontal rollers 220 are arranged in a stepped manner in the vertical direction. Two adjacent horizontal rollers 220 can form a guide opening, thereby forming two guide openings of different heights. Therefore, the guide opening of the corresponding height can be flexibly selected according to the required outlet height, which is more flexible to use.

[0033] As an optional embodiment, the guide mechanism 200 also includes at least one vertical roller 240, which is arranged in the guide frame 210 and close to the inner wall of the guide frame 210. The structure of the vertical roller 240 is the same as that of the horizontal roller 220, and the vertical roller 240 is located between two adjacent horizontal rollers 220 in the upper and lower directions.

[0034] In this embodiment, due to the different directions of the pipeline 500 being retracted and released, the pipeline 500 may contact the inner wall of the guide frame 210. Therefore, vertical rollers 240 can be set on both sides of the guide frame 210, so that they can contact the pipeline 500 for low-wear guiding, so that they can fully adapt to the retraction and release of the pipeline 500 in different directions, with good applicability, and further improving the service life of the pipeline 500. Here, the vertical roller 240 is located between the two adjacent horizontal rollers 220, that is, the axis lines of the vertical roller 240 and the horizontal roller 220 are not in the same vertical plane, and have a certain angle, which is conducive to full contact with the pipeline 500, and is convenient for disassembly, replacement and assembly, with reasonable space layout and compact structure.

[0035] As an optional embodiment, the horizontal roller 220 includes a mounting shaft 221, a guide sleeve 222, a limit piece 223 and a limit ring 224. The mounting shaft 221 is movably connected to the two side walls of the guide frame 210, the guide sleeve 222 is movably mounted on the mounting shaft 221, the limit piece 223 is radially and detachably connected to one end of the mounting shaft 221 extending out of the guide frame 210, the limit ring 224 is connected to the other end of the mounting shaft 221 extending out of the guide frame 210, and the diameter of the limit ring 224 is larger than the diameter of the mounting shaft 221.

[0036] In this embodiment, when the pipeline 500 is being wound or released, the guide sleeve 222 can be driven to rotate accordingly, thereby playing a low-wear guiding role. The limiting rings 224 and the limiting members 223 on both sides of the mounting shaft 221 play a limiting and anti-slipping role. When disassembly is required, the limiting member 223 can be removed, and the mounting shaft 221 can be pulled out in the direction of the limiting ring 224. At the same time, the guide sleeve 222 is also pulled out from the mounting shaft 221, so as to facilitate the replacement of guide sleeves 222 of different diameters or replacement of damaged parts, thereby improving versatility and having a wide range of applications. The horizontal roller 220 here has a quick disassembly and assembly function to meet more usage requirements.

[0037] It should be noted that the limiting member 223 here can be a screw threadedly connected to the installation shaft 221, or a pin assembled with the installation shaft 221, so as to achieve the detachable and limiting functions, and a structure that can be disassembled in other directions can also be adopted.

[0038] As an optional implementation, the horizontal roller 220 and the vertical roller 240 are both made of steel with a smooth surface and are wear-resistant, which can further reduce the wear on the pipeline 500.

[0039] As an optional embodiment, two connecting ear plates 230 for movably connecting the corresponding horizontal rollers 220 are provided on the inlet side and the outlet side, so that the horizontal rollers 220 can be located outside the guide frame 210, further avoiding contact between the pipeline 500 and the edge of the guide frame 210, thereby reducing the risk of scratching and wear of the pipeline 500.

[0040] As an optional implementation, a first support column 250 is connected to the bottom of the guide frame 210 so that the guide frame 210 has a certain height. The first support column 250 can be a hollow tube to save materials.

[0041] It should be noted that the guide frame 210 can be detachably connected to the first support 250 by bolts, so as to facilitate replacement of guide frames 210 of different specifications to meet different requirements for retracting and releasing the wires.

[0042] As an optional implementation, both outer side walls of the guide frame 210 are provided with reinforcing ribs 400, which improve the strength of the guide frame 210 and make the structure more reliable and stable.

[0043] As an optional embodiment, the winding mechanism 100 includes a second pillar 110, a connecting frame 120 and a winding drum 130, the connecting frame 120 is arranged on the top of the second pillar 110, the winding drum 130 is connected to one side of the connecting frame 120, and the winding drum 130 is used to wind the pipeline 500.

[0044] In this embodiment, when the pipeline 500 is retracted or released, the movable cylinder 132 can rotate accordingly. When retracting the line, the movable cylinder 132 can be rotated in the opposite direction to recover the pipeline 500. The retaining ring 133 can prevent the pipeline 500 from escaping, so that it is stored in the storage space surrounded by the retaining ring 133 and the movable cylinder 132.

[0045] It should be noted that the connecting frame 120 can be detachably connected to the second support 110 and the winding drum 130 by bolts, so that the winding drum 130 of different specifications or the connecting frame 120 of different heights can be replaced to meet different winding requirements.

[0046] As an optional embodiment, the winding reel 130 includes a connecting cylinder 131, a movable cylinder 132 and at least two retaining rings 133, the connecting cylinder 131 is connected to one side of the connecting frame 120, the movable cylinder 132 is movably sleeved on the connecting cylinder 131, the pipeline 500 is wound on the movable cylinder 132, the retaining ring 133 is connected to the connecting cylinder 131, the movable cylinder 132 is located between two adjacent retaining rings 133, and the diameter of the retaining ring 133 is larger than the diameter of the movable cylinder 132.

[0047] In this embodiment, when the pipeline 500 is released, the movable cylinder 172 can rotate accordingly. When the pipeline 500 is recovered, the movable cylinder 172 can be rotated in the opposite direction to recover the pipeline 500. The retaining ring 173 can prevent the pipeline 500 from escaping and store it in the storage space surrounded by the retaining ring 173 and the movable cylinder 172.

[0048] It should be noted that, generally, two retaining rings 133 are provided here. In some special structures, more than two retaining rings 133 may be provided, for example, three. In this case, movable cylinders 132 may be respectively provided between adjacent retaining rings 133, and a total of two movable cylinders 132 are provided, thus forming two storage spaces for accommodating the pipeline 500, so that two bundles of pipelines 500 can be wound at the same time, and the sizes of the two bundles of pipelines 500 may be the same or different, so that the pipelines can be released and reeled in at the same time, meeting more usage requirements and having strong flexibility.

[0049] As an optional embodiment, it also includes a base 300, and the first pillar 250 and the second pillar 110 are both arranged on the base 300. The base 300 can limit the relative position of the winding mechanism 100 and the guide mechanism 200 to prevent relative movement. Here, the first pillar 250 and the second pillar 110 can be detachably connected to the base 300 by bolts, which is convenient for adjusting the relative position of the two and flexible to use.
