"Sprinkler trucks" on the railway
Have you seen it?
Recently, in China Railway Lanzhou Bureau Group Co., Ltd
The first phase of the Longhai Railway was repaired on site
A train of rail grinding cars
Sparks flew all the way, and "the clouds drove the fog".
It's eye-catching
01
Uncover the mystery of the "sprinkler truck".
The "sprinkler truck" in the picture
The scientific name is GMC-96x rail grinding car
It belongs to Lanzhou Bureau Group Company
Comprehensive maintenance workshop of Lanzhou Public Works Machinery Section
Rail grinding car
It generally consists of 5 vehicles
Among them, No. 1, 2, 4 and 5 are operation vehicles
The No. 3 car in the middle is a power car
One side of each work truck
There are 3 grinding areas
Grinding the rails
It can improve the wheel-rail contact relationship
Extend the service life and maintenance cycle of railway equipment
Make the train running through the line run more smoothly
So why is it called a "sprinkler truck"?
Let's move on
02
The big role of the "sprinkler truck".
During rail grinding operations
The grinding stone that rotates at high speed rubs against the rail
会产生大量火花和高温飞溅物
Sections along the railway
It is overgrown with shrubs and lush grasses
Especially in winter and spring, the climate is dry
If it is not handled properly, it is easy to cause fire
!
The evolutionary path of the "sprinkler truck".
In order to eliminate the fire hazards brought about by the construction, Lanzhou Public Works Machinery Depot actively transforms the fire protection hardware facilities of large-scale road maintenance machinery, and the technical personnel through on-site actual research, on the basis of the original water spray system of the rail grinding car, the use of the 3000 liters of fire water tank brought by the original car of No. 1 and No. 5 cars, the installation of electronic adjustable frequency conversion pumps, control valves, fan-shaped sprinklers, design and improve the connection pipeline, spray angle, to achieve full coverage of spraying within 4 meters on both sides of the grinding car.
When working in key fire prevention areas
Fire water mist sprayed by rail grinding trucks
It can effectively suppress grinding dust
It can also extinguish the sparks that spill out during the grinding process
03
Hydrate and continue to "fight"
Machinery and equipment can also be "thirsty"
Rail grinding cars with a water consumption of up to 6,000 litres per day
How do I hydrate?
This question is given to its "water partner" - the water tanker
At the rear of the camping vehicle for workers in the Lanzhou Public Works Machinery Section
Hanging a flatbed tanker
There are 4 water tanks with a capacity of 5000 liters on board
Stop at the station closest to the operation section
Reserve water for rail grinding cars
In order to implement fire safety control measures for spring construction
Before the construction of the "skylight" work point
Personnel from relevant units will investigate in advance
Tree cover in the sanding section
Check the location of flammable materials
Do a good job of fire spraying during grinding
04
Intensive cultivation is in full swing
With the continuous growth of rail passenger and freight traffic
Train density has increased further
In order to ensure that the line facilities and equipment are in good condition
Lanzhou Bureau Group Company is advancing in an orderly manner
The first phase of the Longhai Railway in the tube is intensively repaired
Relevant units "fought fiercely" day and night
Let the Spring Festival travel period run at high load
The line facilities and equipment have been repaired and restored in a timely manner
The scene was full of sparks and heat
Track change, screening, tamping, grinding, etc
Different types of construction equipment take turns
Relax muscles and bones, and have a comprehensive physical examination
After undergoing intensive revision
The line will be in better condition
Carrying the steel dragon galloping forward
