It consists of cleaning and screening vehicles, tamping vehicles, power stabilization vehicles, etc
Large-scale road maintenance machinery and equipment
Composed of the "Mecha Corps"
Successively opened the Tangbao and Baolan railways
Replace long rails in sections and mechanically replace sleepers
and the bottom breaking and screening construction is in full swing

The annual overhaul construction officially kicked off
Tangbao Railway and Baolan Railway are important transportation arteries for passenger and freight transportation in the autonomous region, which play an important role in serving the economic and social development of the autonomous region by carrying out a series of overhaul constructions to eliminate hidden dangers in a timely manner, comprehensively improve the quality of line equipment, ensure the safety and smoothness of the railway, and the safety and stability of passenger and freight transportation.
In the early morning, on the railway line between Gongjiban and Chasuqi on the Tangbao Line, the lights were bright and the sound of bagpipes sounded, and more than 400 operators drove more than 40 mechanical vehicles to carry out mechanical cleaning and screening construction in an intense and orderly manner.
Everyone cheered up, paid attention to safety, and worked in strict accordance with the standards to ensure construction safety.
The mechanical car arrives at the operation site, accompanied by a long sound of bagpipes, the preparation work such as the alignment of the mouth and the chain connection is over, the cleaning and screening car increases the engine speed, the excavation chain rotates rapidly, the stone ballast under the sleeper is dug up together with cinder, crushed ballast and spoil, and is sent into the vibrating screen through the rising guide groove for screening, and the clean stone ballast after screening falls into the track bed through the backfill device, and the spoil enters the material car in front along the guide groove.
After the operation of the cleaning and screening truck, the following ballast truck opens its "arms" to deploy and shape the stone ballast scattered on the line. Subsequently, the tamping vehicle waved the "iron claw" and inserted it vertically into the stone ballast to vibrate and compact the ballast. Immediately afterwards, the stabilizing vehicle drove over to stabilize the track bed and improve the stability of the line.
The same busy scene was also staged successively at the construction site of replacing long rails in sections between Sandaoying and Fushengzhuang, Basumu and Hulu, and the mechanical sleeper replacement construction site between Bayangole and Linhe on the Baolan Line.
In the face of the actual situation of many types of construction, long fronts, heavy tasks, large temperature difference between day and night, and low temperature in local areas, the construction personnel uniformly deployed machinery and equipment, road materials and materials, etc., to realize the "one game of chess" linkage of regional operations and ensure the safe and orderly progress of various operations.
The operator arrives at the designated construction location to loosen the nut and remove the fastener. The north wind was howling at the site, bringing a chill, but the construction team was in full swing. At the same time, the operator inserted the crowbar and the rail turner, and the two "decommissioned" old rails lay on the shoulders of the road, slowly dialing in the new rails.
All-round and whole-process card control of on-site security risks, give full play to the operational advantages of large-scale "mecha corps", maximize the use of large machinery and equipment, and achieve both construction progress and efficiency.
During the construction, the pillow hook machine stretched the "long arm", flexibly rotated the body, excavated the mouth, clamped and pulled out the old pillow, moved out of the line, and after two 90-degree rotation of the whole body, the new pillow was smoothly penetrated and accurately aligned, and then the ground cooperated with the personnel to quickly install the fastener and backfill the ramming bed...... The whole sleeper replacement process is smooth and smooth, and the sleepers are threaded under the track one by one.
Implement the "wall chart operation", formulate targeted control measures for mechanical failures and bad weather, improve the emergency response plan, strictly implement the operation standards, check the quality of the operation, open the release train gate, and ensure that the quality of the line meets the standards.
The "Mecha Corps" is a railway
Perform a thorough "rehabilitation surgery"
Guarding the railway transport channel "strong muscles and strong bones"
Let passengers sit in a safe and comfortable car
