"Re-testing the installation height of the dowty retarder is 56 mm, which is in compliance with the regulations." At 13:00 on December 23, at the hump dowty retarder area of the marshalling yard of Shushupu station, Wang Lin, the assistant engineer of the station, was lying in the center of the shaft with his face almost close to the surface of the rail. Use a height ruler to carefully measure the height of the newly replaced dowty retarder, and ensure that the distance between the top of the "mushroom head" and the rail surface is between 55 and 58 mm.
On the first road, the college students of the new approach will quickly check the prepared new dowty retarder, accessories, and tools in advance and stack them according to the order of replacement and by model. The employee Zhai Yingcong and the workers kept using a torque wrench to loosen the stud bolts, disassemble the old dowty retarder, install the new roof, adjust the installation height, re-inspect, and tighten the new dowty retarder. The dowty retarder replacement process was done in one go. On that day, the replacement and testing of 88 retarders were successfully completed safely and successfully within the 105-minute sunroof period.
The dowty retarder is a common shunting equipment placed in the hump marshalling area of the marshalling yard. It uses hydraulic principles to adjust the rolling speed of the vehicle through the rolling of the vehicle wheels. The speed of the vehicle released from the hump passes through the dowty retarder, and the speed will be reduced. Slowly reduce it. With the use of the hump, the efficiency of shunting and marshalling operations can be greatly improved after the dowty retarder is decelerated, and trucks traveling from north to south can reach their destinations faster.
These "iron mushrooms" that grow in the stock road have been working on the hump of the reading shop for 6 years. The surface of the vehicles that have been used for slipping has been severely worn out, and the performance indicators of internal parts have declined severely, which poses a certain degree of safety hazards. In order to ensure the safety of the shunting, from December 16 to 28, the reading shop station carried out a centralized replacement of 1,098 controllable dowty retarder from 1 to 8 in the marshalling yard.
In order to ensure the smooth progress of the overhaul of the dowty retarder replacement, the station organized in advance the 8 retarder employees involved in the replacement operation and 7 new college students who assisted in the operation to conduct labor safety and business skills training. The station assistant engineer Wang Lin strengthened the security card control of the maintenance skylights, and strictly implemented the operation standards for plan submission and approval, registration, and confirmation procedures for opening conditions.
