[0002] Subway reducers usually refer to pipe connection components used in subway tunnels or ventilation systems. The main function of reducers is to connect pipes of different diameters so that the pipeline system can transition smoothly and avoid turbulence or pressure loss when the fluid flows through the pipeline. When processing reducers, positioning and marking of reducers is a key step in pipeline construction, which aims to ensure that the reducers are accurately installed in the specified position, ensuring the smooth connection of the pipeline system and the quality of the overall project.

[0003] When marking subway reducers, existing marking devices often do not clean the surface of the reducers. During the transportation of the reducers, dust and other stains may adhere to the surface due to subway construction, which may cause unclear marking and affect the marking effect.

[0016] The present invention provides a subway reducer positioning and marking device, which has the following beneficial effects: when in use, the surface of the reducer can be completely cleaned to avoid unclear marking due to dirt adhering to the surface of the reducer during marking, and the device can be adjusted as needed to change the marking point and ensure clear marking.

[0017] 1. When the present invention is in use, the reducer is pushed between the cleaning plates, and the reducer can apply pressure to the slide bar through the cleaning plates, pressing the slide bar to slide in the sleeve and compressing the buffer spring. At the same time, the cleaning plate can rotate on the slide bar, so that the cleaning plate can always fit the surface of the reducer. The motor is started, and the motor can drive the driving wheel to rotate, thereby driving the rotating drum to rotate through the tooth groove, so that the rotating drum drives the cleaning plate to move around the reducer through the sleeve and the slide bar, and then the cleaning plate cleans the residual stains on the surface of the reducer to make its surface smooth. The partition frame can limit the rotating drum through the embedded groove, so To maintain the stability of the rotating drum during rotation, after the reducer leaves the inner side of the rotating drum, the slide bar can rebound under the action of the buffer spring, which is convenient for processing the next reducer, and the limit plate can limit the slide bar to prevent the slide bar from rebounding too much and escaping from the sleeve, and in the process of pushing the reducer, the buffer spring can apply force to the reducer evenly through the slide bar, so that the central axis of the reducer always coincides with the central axis of the rotating drum, avoiding the deflection of the reducer and causing skewed marking. In summary, when in use, the surface of the reducer can be thoroughly cleaned to make its surface smooth and dirt-free, thereby ensuring the marking quality.

[0018] 2. Before use, the present invention can adjust the position of the pressure sensor according to the marking position on the reducer. During adjustment, the gear ring is rotated in the rotating groove to drive the transmission wheel to rotate in the transmission groove, thereby driving the adjusting rod to slide in the adjusting groove to adjust the position of the pressure sensor in the sleeve. The reducer is pressed by the cleaning plate to drive the sliding rod to slide on the sleeve. When the limit plate contacts the pressure sensor, it indicates that the marking position has been reached. The marker can be controlled to mark the reducer, and the adjusting spring can ensure that the sliding rod can continue to slide on the sleeve after the limit plate contacts the pressure sensor, so that the sliding rod will not hinder the movement of the reducer. In summary, the device can be adjusted according to the marking position before marking, so as to locate the marking position.

[0019] 3. When processing the reducer, the present invention first sends the end with a smaller diameter through the partition into between the cleaning plates. When pushing the reducer, the pad can provide support for the reducer. At the same time, the water pump can draw water in the water tank into the water passage cavity through the water inlet pipe, and spray it onto the reducer from the nozzle to rinse the reducer and preliminarily clean the dirt adhered to the reducer. The water flow carrying the dirt slides down the pad along the groove and enters the water tank from the water inlet. The filter frame can filter the water flow, thereby intercepting the dirt in the water flow to prevent the dirt from mixing into the circulating water in the water tank and causing the water inlet pipe to be blocked. After the reducer passes through the rotating drum, the vacuum pump can draw the air on the water surface of the partition on one side of the water tank from the vacuum pipe into the ring pipe, and spray it onto the reducer through the air outlet to remove the water droplets remaining on the reducer to prevent the water droplets from affecting the marking. When the air on one side of the partition is reduced, the outside air can enter the water tank from the dust hood through the pipeline to filter the air on one side of the partition. In addition, the smoke generated during laser marking can be removed to prevent the smoke from spreading and affecting the marking, and to prevent the smoke from causing harm to the operator. The smoke can be dissolved in the circulating water after entering the water tank with the air to prevent the smoke from being sprayed out again through the ring pipe, and the filter can prevent the smoke from entering the circulating water between the partitions, causing it to be pumped into the water passage cavity along with the circulating water by the water pump. When the water level in the water tank is too high, the circulating water can overflow from the overflow port to prevent the circulating water from overflowing the suction pipe and being pumped into the suction machine, causing damage to the suction machine. When adjusting the pressure sensor, the threaded rod can be rotated on the partition frame to adjust the height of the bottom plate, so that the distance between the marker and the marking position of the reducer is maintained at an appropriate distance, thereby ensuring the marking quality. The limit rod can limit the bottom plate to prevent the bottom plate from tilting when moving. In summary, the reducer can be rinsed and residual water droplets can be removed during use to avoid affecting the marking effect, and the smoke generated by marking can be extracted.
