The cotter pin is arranged on the pin shaft, is arranged outside the lower anti-falling piece and is used for axially positioning the pin shaft, and is made of high-quality steel with good elasticity.
Wherein the interval distance between the lower retaining member 41 and the upper retaining member 42 is smaller than the minimum distance by which the contact 31 is disengaged from the accommodation groove 20 in the moving direction of the lower vehicle body 1. When the lower vehicle body 1 starts to start or brake along the track, the matched lower anti-drop piece 41 and the matched upper anti-drop piece 42 generate adaptive displacement along the pin shaft under the action of impact force, the displacement is smaller than or equal to the interval distance between the matched lower anti-drop piece 41 and the matched upper anti-drop piece 42, and the cotter pin generates certain elastic deformation along with the displacement. The impact caused by the rail start or brake of the lower car body 1 is largely counteracted by the combined cushioning effect of the cooperating lower and upper drop-out preventing members 41, 42 and cotter pins and the cooperating contact 31 and receiving groove 20.
Wherein the contact 31 extends in the extending direction of the lower retaining member 41, and the length of the kidney-shaped hole is smaller than the depth of the contact 31 extending into the accommodating groove 20. Under the impact generated when the grab bucket 203 starts to grab and drop the weight or when the motor 2011 is started and braked, the upper car body 2 can jump relative to the lower car body 1, and the pin shaft can move along the length direction of the kidney-shaped hole. The cooperation of the pin with the kidney-shaped hole largely counteracts the impact caused by the runout of the upper body 2.
