Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, and in particular to a gas pipeline cleaning device. Background Technology

[0002] Over long-term use, gas pipelines accumulate various impurities, dirt, and deposits, such as rust, coal tar, and dust. These impurities not only affect the efficiency of gas transmission but can also lead to safety problems such as pipeline blockage and leaks. Currently, gas pipeline cleaning devices are used to clean the pipelines. However, traditional gas pipeline cleaning devices can mostly only clean the inner walls of pipelines of one size, failing to effectively clean the inner walls of pipelines of different sizes. This creates difficulties for personnel cleaning the pipelines.

[0003] Existing technology CN215696505U discloses a fine desulfurization gas pipeline cleaning device, including a frame and an adjustment device disposed away from the side wall of the frame. The adjustment device includes a turntable, a rotating rod, a take-up roller, a pull rope, and a fixing rod. The turntable is located in the middle position away from the side wall of the frame. This utility model utilizes the coordinated use of the turntable, rotating rod, take-up roller, pull rope, compression spring, fixing rod, and cleaning rod. When cleaning a gas pipeline is required, the position of the cleaning rod is first adjusted according to the size of the gas pipeline. By rotating the turntable, the rotating rod rotates, which in turn rotates the take-up roller, causing the pull rope to loosen. Through the setting of the compression spring, the fixing rod moves the cleaning rod outward. At this time, the device can be installed inside the pipeline to clean the inner wall of the pipeline. This makes the device applicable to pipelines of different sizes, improving the applicability of the device and bringing convenience to personnel cleaning pipelines.

[0004] Although the aforementioned desulfurized gas pipeline cleaning device can be applied to pipelines of different sizes, it requires manual operation for adjustment, which is not very convenient. Utility Model Content

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the gas pipeline cleaning device of this utility model. Figure 2 This is a structural schematic diagram of the positioning housing 104 of this utility model. Figure 3 This is a structural schematic diagram of the support frame 113 of this utility model.

[0019] This utility model discloses a gas pipeline cleaning device, comprising a fixed frame 101, a drive shaft 102, a positioning rod body 103, a positioning housing 104, an adjusting screw 105, a first slider 106, a second slider 107, an adjusting motor 108, a first support arm 109, a second support arm 110, a limiting rod 111, a connecting block 112, a support frame 113, and a conductive slip ring 114. It solves the problem that while existing technologies can be applied to pipelines of different sizes, they require manual adjustment, resulting in poor convenience. It is understood that the aforementioned solution can also be used to improve the level of automation.

[0020] In this embodiment, the fixing frame 101, the drive shaft 102, and the positioning rod body 103 are all prior art. The fixing frame 101 is used to fix the device to the gas pipeline, the drive shaft 102 plays a driving role, and the positioning rod body 103 is provided with a cleaning plate for cleaning the inner wall of the gas pipeline. The specific structure of the fixing frame 101, the drive shaft 102, and the positioning rod body 103 refers to the prior art CN215696505U, a fine desulfurization gas pipeline cleaning device. Through the adjustment component, the positioning rod body 103 can be conveniently adjusted, which solves the problem that although the prior art can be applied to pipelines of different sizes, it requires manual operation for adjustment, resulting in poor convenience.

[0021] The positioning housing 104 is fixedly connected to the transmission shaft 102 and located at one end of the transmission shaft 102. The adjusting screw 105 is rotatably connected to the positioning housing 104 and located on the side of the positioning housing 104 away from the transmission shaft 102. The first slider 106 is sleeved on the outside of the adjusting screw 105 and threadedly connected to the adjusting screw 105. The second slider 107 is sleeved on the outside of the adjusting screw 105 and threadedly connected to the adjusting screw 105. The adjusting motor 108 is installed inside the positioning housing 104, and the output shaft of the adjusting motor 108 is connected to... The adjusting screw 105 is fixedly connected. The connecting member connects the positioning rod body 103 to the first slider 106 and the second slider 107. The limiting member limits the first slider 106 and the second slider 107. The positioning housing 104 is a metal housing with an internal cavity. The positioning housing 104 is fixedly connected to the end of the transmission shaft 102 through a flange, so that the positioning housing 104 can rotate with the rotation of the transmission shaft 102. The end of the adjusting screw 105 extends into the positioning housing 104 and is connected to the positioning housing 104 through a bearing. Both the first slider 106 and the second slider 107 have threaded through holes. The adjusting screw 105 is a bidirectional screw with opposite thread directions at both ends. The first slider 106 and the second slider 107 are respectively sleeved on both ends of the adjusting screw 105 through the threaded through holes. The adjusting motor 108 is bolted and installed in the positioning housing 104 to drive the adjusting screw 105 to rotate. There are two positioning rod bodies 103, which are connected to the first slider 106 and the second slider 107 through two sets of connecting components. The limiting component can prevent the first slider from... The first slider 106 and the second slider 107 rotate with the rotation of the adjusting screw 105. The adjusting motor 108 drives the adjusting screw 105 to rotate, causing the first slider 106 and the second slider 107 to move synchronously in opposite directions. Through the transmission of the connecting member, the two positioning rod bodies 103 can synchronously expand or contract to achieve adjustment. This application only needs to control the action of the adjusting motor 108 to achieve adjustment conveniently and quickly, solving the problem that although the prior art can be applied to pipes of different sizes, it requires manual operation for adjustment, which is not very convenient.

[0022] Secondly, the two ends of the first support arm 109 are rotatably connected to the first slider 106 and the positioning rod body 103, respectively; the two ends of the second support arm 110 are rotatably connected to the second slider 107 and the positioning rod body 103, respectively. The two ends of the first support arm 109 are connected to the first slider 106 and the positioning rod body 103 through hinges, and the two ends of the second support arm 110 are connected to the second slider 107 and the positioning rod body 103 through hinges. The first support arm 109 and the second support arm 110 are arranged in a V-shape. By moving the first support arm 109 and the second support arm 110 with the movement of the first slider 106 and the second slider 107, the positioning rod body 103 can be adjusted.

[0023] Meanwhile, the limiting rod 111 is fixedly connected to the positioning housing 104 and slidably connected to the first slider 106 and the second slider 107 respectively; the connecting block 112 is rotatably connected to the adjusting screw 105 and fixedly connected to the limiting rod 111. The limiting rod 111 is a smooth cylinder, parallel to the adjusting screw 105. The first slider 106 and the second slider 107 are each provided with a through hole matching the diameter of the limiting rod 111. The limiting rod 111 passes through the through hole and is slidably connected to the first slider 106 and the second slider 107. The connecting block 112 is disposed at the end of the limiting rod 111. The adjusting screw 105 is connected to the connecting block 112 through a bearing. The connecting block 112 can connect the ends of the adjusting screw 105 and the limiting rod 111 together, thereby improving stability. The limiting rod 111 can prevent the first slider 106 and the second slider 107 from rotating, thereby achieving limiting.

[0024] In addition, the support frame 113 is fixedly connected to the positioning housing 104 and the connecting block 112. The support frame 113 is U-shaped and connects the connecting block 112 to the positioning housing 104. Through the support frame 113, the suspended end of the adjusting screw 105 and the limiting rod 111 is stably supported, thereby improving the overall stability of the device.

[0025] Finally, the conductive slip ring 114 is sleeved on the outside of the transmission shaft 102. The regulating motor 108 is electrically connected to the conductive slip ring 114. The external power line passes through the fixing frame 101 and is connected to the terminal block of the stator part of the conductive slip ring 114. The regulating motor 108 is connected to the terminal block of the rotor part of the conductive slip ring 114 through a wire. Through the conductive slip ring 114, cable tangling can be avoided, and power transmission during continuous rotation can be realized.

[0026] In this embodiment, a driving device is provided on the fixing frame 101, which can drive the transmission shaft 102 to rotate. In use, the two positioning rod bodies 103 are adjusted to appropriate positions according to the inner diameter of the gas pipeline, ensuring that the cleaning plate on the positioning rod body 103 is in contact with the inner wall of the gas pipeline. During adjustment, the rotation of the adjusting motor 108 is controlled, and the adjusting motor 108 drives the adjusting screw 105 to rotate. Simultaneously, the rotation of the adjusting screw 105 causes the first slider 106 and the second slider 107 to move towards or away synchronously. When the first slider 106 and the second slider 107 move towards each other synchronously, the two positioning rod bodies 103 move synchronously... The inward contraction allows for cleaning of smaller diameter pipes. When the first slider 106 and the second slider 107 move away synchronously, the two positioning rod bodies 103 expand outwards synchronously, allowing for cleaning of larger diameter pipes. After adjusting the position of the positioning rod body 103, it is inserted into the gas pipe and fixed to the gas pipe by the fixing frame 101. Activating the drive device on the fixing frame 101 drives the positioning rod body 103 to rotate, cleaning the inside of the gas pipe. This application allows for convenient and quick adjustment of the positioning rod body 103 by controlling the action of the adjusting motor 108, solving the problem that while existing technologies can be applied to pipes of different sizes, they require manual adjustment, resulting in poor convenience.
