Detailed description of the invention
As shown in Figure 1, a kind of Double Tops pin suspender for preventing flat rack container from falling case accident, comprises tapered end, is arranged on twist lock 1 on casing 12 and lifting pin mechanism.Twist lock 1 arranges two lifting pin mechanism being positioned in tapered end line of centers symmetric position, forms the structural shape of Double Tops pin; Lifting pin mechanism side installation and measuring inhibiting device, and be in series with ejector pin is spacing, realize chain control.
Every corresponding a set of ejector pin device of tapered end.Install ejector pin B3 at former ejector pin A2 additional about the position of tapered end line of centers symmetry, form the structural shape of Double Tops pin at each twist lock place, its positional structure as shown in Figure 2.By spacing in upper box 12 installation and measuring, and be in series with former ejector pin is spacing, realize chain control.A suspender has four twist locks 1, need install the ejector pin device of four these structural shapes of cover and spacing additional.
Adopt the structure design of Double Tops pins, when occur tapered end lockhole outer case time, no matter which kind of incorrect position relationship ejector pin is in corner post contact surface, effectively can stop the generation of lockhole locking outward.
As shown in Figure 2, lifting pin mechanism comprises ejector pin B3, limit induction block 6, guide fixed block 5, spring 4, described ejector pin B3 top is through upper box 12, bottom to penetrate at the bottom of case 13, guide fixed block 5 and limit induction block 6 are equipped with in its upper end, top, the Step Shaft of ejector pin B3 bottom is equipped with spring 4, and is locked with nut 7, spring 4 one end contacts with upper box 12 and connects, and the other end contacts with the boss of the Step Shaft of ejector pin B3 and connects.
