Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, specifically a support device for sewage pipeline maintenance. Background Technology

[0002] Pipelines are devices made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Sewage pipelines are devices used to transport domestic, municipal, and industrial wastewater and waste. Sewage pipelines are easily damaged and aged, requiring maintenance. When maintaining sewage pipelines, they need to be supported, so support devices are required.

[0003] A search revealed a Chinese patent document disclosing a support device for heating pipe maintenance [Publication No.: CN221160034U]. This support device for heating pipe maintenance includes a telescopic mounting rod 1, an adjusting screw 2, a bottom fixing ring 3, an upper fixing ring 4, a support member 5, and a straightening mechanism 6. The telescopic mounting rod 1 is threadedly connected to the adjusting screw 2 on both the left and right sides. The bottom fixing ring 3 is connected to the top of the adjusting screw 2, and the upper fixing ring 4 is snapped onto the bottom fixing ring 3. The support member 5 is connected to the middle of the telescopic mounting rod 1, and the support member 5 is equipped with a straightening mechanism 6 for straightening the heating pipe during maintenance.

[0004] The support device for repairing heating pipes disclosed in this patent first removes the pipes that need to be repaired for repair. The support device can adjust the angle and direction of the pipes. Since the pipes are rotated by friction, the entire pipe can be rotated and adjusted, allowing workers to repair the pipes. However, due to the weight of the pipes, the rotation of one end of the pipe driven by friction is relatively unstable and is prone to slippage or failure to rotate. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4As shown, a support device for sewage pipeline maintenance includes a support base 1, which supports the device and enables it to operate. A mounting shell 2 is installed above the support base 1. A rotating shell 3 is slidably connected to the inner cavity of the mounting shell 2. A limit assembly 4, consisting of a lead screw and a limit block, is provided on the surface of the rotating shell 3. Under the action of the limit assembly 4, the two ends of the pipeline can be limited within the inner cavity of the rotating shell 3, allowing workers to perform pipeline maintenance. A stepper motor 5 is installed on one side of the mounting shell 2, and the output shaft of the stepper motor 5 is fixedly connected to... A spur gear 6 is connected, which can rotate under the action of a stepper motor 5. A gear ring 7 meshes with the surface of the spur gear 6, and the surface of the gear ring 7 is fixedly connected to the surface of the rotating housing 3. The central axes of the rotating housing 3 and the gear ring 7 are on the same horizontal line. With the cooperation of the stepper motor 5 and the spur gear 6, the gear ring 7 can drive the rotating housing 3 to rotate within the inner cavity of the mounting housing 2. This allows workers to adjust the angle of the pipeline by rotating the housing 3, facilitating maintenance and reducing the workload of workers. A guide block 12 is fixedly connected to the surface of the rotating shell 3. The surface of the guide block 12 is slidably connected to the inner cavity of the mounting shell 2. Under the action of the guide block 12, the positional deviation of the rotating shell 3 during rotation is effectively reduced, increasing the stability of the rotating shell 3 and thus improving the stability of the device. The output shaft of the stepper motor 5 is fixedly connected to a rotating telescopic rod 8. The other end of the rotating telescopic rod 8 is fixedly connected to the surface of another spur gear 6. With the cooperation of the stepper motor 5 and the rotating telescopic rod 8, the spur gears 6 on both sides can rotate simultaneously, so that the gear rings 7 on both sides can drive the pipe to adjust the angle through the rotating shell 3. This increases the stability of the operator in adjusting the angle and direction of the pipe, thereby improving the practicality of the device. A connecting block 9 is fixedly connected to the bottom of the mounting shell 2. An adjustment mechanism 10 is set below the connecting block 9. One end of the rotating telescopic rod 8 passes through to one side of the connecting block 9 and is rotatably connected to it. With the cooperation of the connecting block 9 and the adjustment mechanism 10, the mounting shells 2 on both sides can move in opposite directions simultaneously, allowing the limiting component 4 to limit pipes of different lengths, thereby improving the practicality of the device.

[0022] The adjustment mechanism 10 includes a hand dial 101 disposed on one side of the support base 1. One end of the hand dial 101 is fixedly connected to a bidirectional threaded rod 102, and the other end of the bidirectional threaded rod 102 is rotatably connected to the surface of the support base 1 on the other side. A movable sleeve 103 is threadedly connected to the surface of the bidirectional threaded rod 102, and the top of the movable sleeve 103 is fixedly connected to the bottom of the connecting block 9. The hand dial 101 has a multi-grooved design, and under the action of the hand dial 101, the bidirectional threaded rod 102 can be rotated on one side of the support base 1. The bidirectional threaded rod 102 is rotatably connected to the surface of the support base 1 via the movable sleeve. 103 causes the connecting blocks 9 on both sides to move in opposite directions simultaneously. The connecting blocks 9 move the rotating shell 3 through the mounting shell 2, allowing the limiting component 4 to adjust its position according to the pipe of different lengths, thereby improving the effectiveness of the device. A guide rod 11 is fixedly connected to the surface of the support base 1. The surface of the guide rod 11 is slidably connected to the inner cavity at the bottom of the moving sleeve 103. Under the action of the guide rod 11, the position of the moving sleeve 103 is effectively prevented from shifting during movement, increasing the stability of the adjusting mechanism 10, thereby improving the stability of the device.

[0023] Working principle: First, when the operator needs to adjust the position of the mounting shell 2 according to the length of the sewage pipe, the operator uses the hand dial 101 to rotate the bidirectional threaded rod 102 on one side of the support base 1. The bidirectional threaded rod 102 moves the connecting blocks 9 on both sides in opposite directions simultaneously through the moving sleeve 103. The connecting blocks 9 move the rotating shells 3 on both sides in opposite directions simultaneously through the mounting shell 2. Then, the operator passes the pipe through the inner cavity of the rotating shell 3, and under the action of the limiting component 4, the pipe can be limited within the inner cavity of the rotating shell 3. Then, the operator performs maintenance on the pipe. When the operator needs to maintain another part of the pipe after maintaining one part of the pipe, the operator uses the stepper motor 5 to spur the gears. Wheel 6 drives gear ring 7 to rotate, which in turn drives rotating shell 3 to rotate within the cavity of mounting shell 2. Under the action of guide block 12, the positional deviation of rotating shell 3 during rotation is effectively reduced. Rotating shell 3 rotates the pipeline through limiting component 4, allowing workers to adjust the angle and direction of the pipeline. At the same time, stepper motor 5 rotates spur gear 6 on the other side through rotating telescopic rod 8. Spur gear 6 on the other side rotates rotating shell 3 on the other side within the cavity of mounting shell 2 through gear ring 7, thus allowing both ends of the pipeline to rotate simultaneously. After the workers have finished repairing the pipeline, they release the limiting component 4 and then move the pipeline out of the rotating shell 3.
