 Brief talk about the ground rail installation of 600-ton gantry crane —— steel backing plate

Introduction of steel backing plate:

steel soleplates

steel soleplates

We also call it steel soleplate. It is an important component of the track structure. The under-rail pad between the rail and the sleeper plays an important role in bearing and vibration reduction in the wheel-rail power system. With the development of heavy-duty high-speed railway transportation, the axle load is increasing day by day. While the rail is heavy, higher requirements are placed on the vibration damping performance, impact resistance, and service life of the backing plate.

1. Track parameters:

Rail model: QU120
Track top width: 120
Track height: 170
Rail width: 170
1.1 Fixing scheme of rails:
Using the continuous rail fixing method purchased by Glory Rail

2. Pre-embedded bolts and steel base plate

2.1 Embedded bolt specifications and anti-rust treatment
Specifications: M24 with hook type embedded bolt
Material: Q235

2.2 Anti-rust treatment
Q235 Steel plate: PL25x360x3000
The flatness requirement of the steel base plate is:
<1mm/1000mm. The steel backing plate needs to be drilled, and the adjustment bolt holes on the steel backing plate are matched with the adjustment bolts M20x105 (GB5786).

2.3 Anti-rust treatment of steel backing plate:
After the pressure plate base is welded to the steel backing plate, remove the rust stains on the steel backing plate and apply a layer of primer (including the base). The top surface of the pressure plate base and the bottom of the steel backing plate does not need to be painted. After the primer is dry, fix the steel backing plate to the embedded bolts. Apply another coat of intermediate coat (including the base). After the middle coat is dry, apply the second top coat (including the base).

3. Installation order:

·Installation of steel base plate
·Measure and adjust the elevation of the steel backing plate
· Welding pressure plate base pouring glue
·Laying rubber pads ·Install the rails according to the technical requirements
· Rail interface welding
·Tighten the plate clamp according to the specified torque

3.1 Installation of steel backing plate

– Before installing the steel backing plate, the loose concrete and laitance on the surface of the foundation concrete should be chiseled, and the floating ash and water should be removed.
– Install the steel backing plate in accordance with the drawings. If rust is found on the bottom of the steel base plate, it should be removed first. Pay attention not to use acetylene flame to enlarge the embedded bolt holes.
– Use adjustment bolts to accurately control the level of the steel backing plate. Each adjustment bolt can be greased to prevent mortar penetration.
– Weld the base of the pressure plate on the steel backing plate according to the requirements of the installation instructions of the pressure plate. For the spacing of the pressure plate, please refer to the requirements of the construction drawings.
-Weld two 180x50x20 connecting steel plates at the connection of each steel backing plate.
– Adjust the level of the steel base plate and pre-tighten the nut.

What are railway rail fasteners?

What are railway rail fasteners? Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...
