18706752192 supplies sea cucumber S & mdash; Composition of type 1 aluminum alloy two-way rerailer: each set includes left and right rerailers (one tread iron, two-way guide edge and rerailer body), one tool box, two backing plates, one wrench, 6 hook lock bolts, 6 nuts and 5 gaskets
Structural features ① this type of rerailer is made of aluminum alloy, with the advantages of light weight and good strength
The rerailer adopts arched arc hollow vertical plate structure, which is equipped with two-way guide edge, tread iron and rerailer backing iron, Reasonable structure and good bearing capacity
Main technical parameters: overall dimension: 900 mm & times; 310 mm× 290 mm, weight: 45
5 kg / piece;, Tensile strength: 350 & mdash& mdash; 380 MPa, elongation: 5
5% ~ 7
5%, surface hardness: hbs97-112
Usage: this type of rerailer is composed of two identical main bodies, which must be used at the same time during lifting operation
The rerailer shall be placed at the same position inside and outside the front rail in the pulling direction, and the ballast shall be properly removed to make it close to the rail
After the rerailer is placed stably, thread the three hook bolts from the bottom of the rail into the mounting hole of the main body of the rerailer and tighten them
③ The track from derailed wheel to rerailer shall be padded with ballast or iron backing plate to reduce the pulling resistance and prevent the sleeper from being damaged
④ When used on heavy rails of 60 kg / M and above, special aluminum backing plates shall be placed on the rail seat and under the small end of the rerailer to avoid damage to the main body of the rerailer
⑤ Before lifting, apply lubricating oil on the guide edge and the top of the main body of the rerailer to facilitate rerailing and reduce the wear of the guide edge
⑥ When the track width of the derailed vehicle exceeds 240 mm of the base rail, the & ldquo; Elevation approximation & rdquo; The derailed wheel is pulled back after it is close to the base rail
In front of the derailed locomotive and one end of the track laying locomotive in the re track direction, select two sleepers according to the distance between the wheel track and the steel rail, place the re track on the outside of the steel rail with large reinforcement, and press the left & ldquo; People & rdquo; Right & ldquo; Enter & rdquo; The structural herringbone rerailer is mainly composed of large reinforcement, small reinforcement, correction reinforcement, rail bolt, rail groove, spike, bolt, fastening bolt, etc
The rear end shall be placed on the sleeper, and then the contact between the head and the rail top shall be padded with anti-skid wood chips or dry cotton wires, rags, etc
, and then the two corners of the rail shall be padded with anti slide nails, and the two sides under the waist shall be filled with stone slag or wood blocks to prevent overturning
The herringbone rerailer shall be installed symmetrically to the left and right, and shall not be placed at the rail joint, so as not to be easy to be leveled due to the influence of fishplate
Do not place on rotten sleepers to avoid unstable nailing
If it is a concrete sleeper, it shall be placed between two sleepers, penetrated into sleepers or short sleeper wood, tamped, placed on the newly penetrated sleepers, adjusted the movement direction of the wheel by using the guide wheel edge and the slope surface to make the wheel rotate from the ground to the top of the rail
Herringbone rerailing uses safety operation regulations 1
Herringbone rerailing or the principle of utility elevation approximation to rerailing the wheel
When lifting, it relies on its two large ribs to force the rim to rise along the surface slope of the rerailing device close to the base rail, and use the correction ribs to adjust the wheel direction to achieve off-line wheel set rerailing When in use, select appropriate sleepers in front of the derailed locomotive and vehicle rerailing direction according to the derailed wheel, the derailment distance of the steel rail and the wheel inclination direction
When the herringbone rerailing device is used, be sure to pay attention to the right entry of left people and do not swing backwards; After the pendulum is reversed, it is a derailer
The effective re track distance of herringbone re track device is 240mm
If it exceeds this range, it is necessary to add a track forcing device
The correct ballast removal method is to remove the ballast on both sides of the rail
The ballast at the tail of the rerailer close to the sleeper also needs to be removed
More ballast shall be removed from the outside of the rail to facilitate the threading of the rerailer
In this way, the rerailer can be placed on the rail smoothly
Precautions: 1
During lifting, rescuers should stay away from the area around the rerailer to prevent the wheel from slipping and crushing the stone slag to hurt people
2
The lower part of the rerailer on the side where the lifting wheel passes shall be filled with crushed stones to prevent the rerailer from overturning and tilting and make the wheel over the guide edge
3
When the wheel is about to reach the top of the rerailer, the speed shall be reduced as much as possible, and the correction rib shall be used to force the wheel to turn, so as to prevent the wheel from crossing the rail and falling off on the other side due to too fast speed
4
The installation of the rerailer shall avoid the influence of the rail joint (there is a fishplate at the rail joint), rail brace and gauge rod on the placement of the rerailer
