This structural design makes things convenient for extension spring pulling L type movable rod to reset, and the convenience is changed it when extension spring damages simultaneously, the convenience when having increased the maintenance.
One ends of the two extension springs, which are far away from the L-shaped movable rod, are respectively sleeved outside the two bolts.
The horizontal sections of the two L-shaped movable rods are respectively arranged below the two steel rail heads at intervals.
The structural design can reduce the friction resistance between the ladder car and the steel rail when the ladder car is pushed, effectively improves the pushing speed, and reduces the labor intensity of operating personnel when the ladder car is pushed.
The transverse supporting rods are arranged in the middle of the two longitudinal beams in the direction perpendicular to the longitudinal beams.
The transverse supporting rod is formed by welding a section of angle steel and two sections of square steel end to end.
This structural design has reduced this device of preventing turning on one's side's manufacturing cost on the basis of guaranteeing this device of preventing turning on one's side structural firmness.
The utility model has the advantages of reasonable design reliably, the purpose that prevents the ladder car and turn on one's side when having realized the implementation, and can carry out smoothly through rail joint department, the security when effectively having improved implementation efficiency and implementation has reduced intensity of labour when the operation personnel carry out the ladder car, convenient equipment simultaneously, convenient dismantlement, convenience when effectively having improved installation and maintenance, it is further, applicable in the operation scene of ladder car longeron and rail interval difference, the suitability further promotes, the structure is simple and easy, low in manufacturing cost's advantage.
