Below, highlighting the front end support device of the embodiment of the invention.
As shown in Figure 3 and Figure 4, have one section linear portion zone to be the zone of action 31 in the swing arm lower end, the spacing of the zone of action 31 of two swing arms of same swing arm set is slightly less than the width of superimposed trailer front end.Guide portion 311 is an inclined-plane on above the zone of action 31, and its effect is the guiding of superimposed trailer when front loaded.Following guide portion 312 below the zone of action 31 also is an inclined-plane, and its effect also is a guiding, the guiding when the superimposed trailer front end is drawn off.Swing arm can be rotated along bearing pin 30, because the scope of rotating is need be restricted, thus in the front end support device of first embodiment of the invention, locating dowel pin 341 and position-limited trough 342 are set, to reach spacing effect.In normal off working state, the upper inner of swing arm is to be in plumbness along 36 substantially, for realizing this state, on U type groove, extension spring seat 331 is set, extension spring 33 is set on it, changes in the U type notch (U type notch 142 external positions of U type device 14 before promptly being in) over to and stop the smooth importing of superimposed trailer front end along 36 to prevent the swing arm upper inner, preferred, the swing arm upper inner is along 36 being to be in plumbness when the off working state, and is more attractive in appearance like this.
Do the time spent when the zone of action 31 of swing arm is subjected to enough external force F, as shown in Figure 4, swing arm will overcome the effect of extension spring 33 and rotate, its result, and bearing surface 32 will be forwarded to the horizontal surface position by original inclined-plane.The inclined-plane adjacent with bearing surface 32 is support guide face 321, and its effect is when supported object falls to bearing surface 32, if when skew taking place and falling support guide face 321, will allow it slide on the bearing surface 32.
The front end support device of first embodiment of the invention realizes that process such as Fig. 5 that the container semi-trailer front end is supported are extremely shown in Figure 10.
As shown in Figure 5, top link group 18 and following swing arm set 19, before the front end of superimposed trailer is not also packed into, all in a state of nature, the top that is swing arm is not in U type notch 142, preferably, each swing arm upper inner all is in plumbness along 36, at this moment helps very much the importing of bottom superimposed trailer front end 241.
When bottom superimposed trailer front end 241 imports downwards, at first be the last guide portion 311 of running into top link group 18, and the lower end of oppressing swing arm set 18 laterally rotate, the upper end then turns to the inside.When further moving down, just enter into the zone of action 31 of top link group 18, the state that swing arm at this moment will be kept rotation is constant, as shown in Figure 6.
When bottom superimposed trailer front end 241 further imports downwards, at first leave top link group 18, at this moment top link group 18 returns to previous status under the effect of extension spring 33.Bottom superimposed trailer front end 241 is to run into down the last guide portion 311 of swing arm set 19 then, and the lower end of oppressing swing arm set 19 laterally rotates, and the upper end then turns to the inside.When further moving down, just enter into down the zone of action 31 of swing arm set 19, at this moment it is constant to descend swing arm set 19 will keep the state of rotation, because the power of replacing of bottom superimposed trailer front end 241 is greater than the pulling force of extension spring 33, the bearing surface 32 of its upper end inwardly stretches out, and in running order, the front end of bottom superimposed trailer just directly drops on the end back-up block 119, as shown in Figure 7.
After the bottom superimposed trailer put in place, 242 beginnings of interlayer superimposed trailer front end imported downwards, as shown in Figure 8.
When interlayer superimposed trailer front end 242 is further packed into downwards, at first be the last guide portion 31 of running into top link group 18, and the compressing swing arm set 18 the lower end laterally rotate, the upper end then turns to the inside.When further moving down, just enter into the zone of action 31 of top link group 18, the state that swing arm at this moment will be kept rotation is constant.When further importing downwards then, the interlayer superimposed trailer will be fallen down on the upper support face 32 of swing arm set 19, as shown in Figure 9.Simultaneously, because middle level superimposed trailer front end 242 is replaced the zone of action 31 of top link group 18, the bearing surface 32 of top link group 18 upper ends stretches out and is in the mode of operation that can support upper strata superimposed trailer front end 243.
At last, upper strata superimposed trailer front end 243 directly is put on the upper support face 32 of top link group 18, as shown in figure 10, thereby finishes support and location three superimposed trailer front end.
In like manner, utilize the following guide portion 312 of each swing arm set, realize the derivation to three superimposed trailer front end, order is just in time opposite.
Core content of the present invention is a principle of utilizing swing arm, instantly after the superimposed trailer of one deck puts in place, swing arm upper end is just stretched the bearing surface of last layer, and in the first embodiment of the present invention, the scope of rotation is that the cooperation by a locating dowel pin 341 and position-limited trough 342 limits.
In order to reach same effect, in the front end support device of second embodiment of the invention, spacing form such as Figure 11 and shown in Figure 12, on U type groove 141, bearing pin 30 respectively establish a limiting stopper, i.e. upper limit position block 351 and lower position block 352 up and down.When off working state, under the effect of extension spring 33, the swing arm upper end is pulled to upper limit position block 24, and be close to, as shown in figure 11.Do the time spent when the swing arm zone of action 31 is subjected to enough big external force F, swing arm will rotate, till the outside, swing arm lower end is close to lower position block 352, as shown in figure 12.
In order to reach same effect, in the front end support device of third embodiment of the invention, spacing form such as Figure 13 and shown in Figure 14, at the lateral surface of swing arm the one side of U type groove 141 (promptly back to), a grooved locating part 38 is established in the top of bearing pin 30, its bathtub construction both ends are fixed on the U type groove 141, and play the position-limiting action of two limit that swing arm is rotated.The interior space of bathtub construction holds swing arm top and rotates therein.When off working state, under the effect of stage clip 37, the limit is inwardly pressed and turned in the swing arm lower end, as shown in figure 13.Do the time spent when the swing arm zone of action 31 is subjected to enough big external force F, swing arm rotates compression press spring 37, outwards rotates up to the swing arm lower end and till the end position, as shown in figure 14, the press spring base 371 of stage clip 37 is arranged on the U type groove 141.
