Detailed description of the invention

The preferred implementation provided this utility model with reference to the accompanying drawings illustrates.

Fig. 1 to Fig. 3, for the preferred implementation of a kind of reversible self-discharging semitrailer that this utility model provides.Such as Fig. 1 extremely Shown in Fig. 3, this semitrailer includes that bicycle beam 10, compartment 20 and four support meanss 30, four support meanss 30 are divided into two rows parallel Be arranged in bicycle beam 10, two support meanss 30 of bicycle beam 10 side can support compartment 20 to opposite side tilt, bicycle beam 10 another Two support meanss 30 of side can support compartment 20 to lopsidedness, such compartment 20 can inclined in two-way, easy to use.

As in figure 2 it is shown, bicycle beam 10 includes two the first bicycle beam 11 and second bicycle beam 12, the second bicycle beam 12 connects two First bicycle beam 11, the height of the second bicycle beam 12 is less than the height of the first bicycle beam 11, and such second bicycle beam 12 is relative to two first Bicycle beam 11 concave downward, whole bicycle beam 10 makes the decentralization of whole semitrailer.Corresponding, compartment 20 includes two the first compartments 21 and second compartment 22, the second compartment 22 connects two the first compartments 21, and two the first compartments 21 are respectively placed at two In first bicycle beam 11, the second compartment 22 is placed in the second bicycle beam 12, and corresponding second bicycle beam 12 in such second compartment 22 is to recessed Falling into, the volume in whole compartment 20 increases, and can load more goods.

As it is shown in figure 1, each first bicycle beam 11 is provided with two support meanss 30, two in same first bicycle beam 11 Spacing between support arrangement 30 is more than the width in the first compartment 21, and two support meanss 30 in same first bicycle beam 11 are in this The both sides in the first compartment 21 in the first bicycle beam 11.In two the first bicycle beam 11, the support means 30 of the same side is in same straight line On, in two the first bicycle beam 11, the support means 30 of the same side supports compartment 20 to opposite side inclination.

As in figure 2 it is shown, each support means 30 includes base 31, support bar 32 and urceolus 33, base 31 is fixed on first In bicycle beam 11, support bar 32 is hydraulic pressure support bar, and the one end of support bar 32 is connected with base 31, the other end of support bar 32 Being socketed in urceolus 33, urceolus 33 is positioned at the side in the first compartment 21.Base 31 is provided with two supports 311 and a bearing pin 312, the bottom of support bar 32 is provided with a through hole 321, and bearing pin 312 is placed in two supports 311 through through hole 321, supports Bar 32 can rotate around bearing pin, so tilt compartment 20 time, the support bar 32 of side, compartment 20 around bearing pin 311 according to compartment 20 rotation directions rotate and support bar 32 gradually stretches out from urceolus 33, and the support bar 32 of compartment 20 opposite side is contracted in urceolus 33 In and rotate around bearing pin 312 according to compartment 20 rotation direction.

Two side bottoms in each first compartment 21 are respectively equipped with first rotary shaft 211.Corresponding, each first bicycle beam 11 are provided with two the first rotation slots 111, the spacing between two the first rotary shafts 211 on the first compartment 21 and the first bicycle beam The spacing between two the first rotation slots 111 on 11 is consistent, and two first rotary shafts 211 in each first compartment 21 are pacified respectively It is placed in two the first rotation slots 111 in corresponding first bicycle beam 11.

It should be noted that the first rotation slot 111 cross section is for semicircle, the internal diameter of the first rotation slot 111 and first turn The diameter of moving axis 211 is identical, the most both can guarantee that the first rotary shaft 211 of side, compartment 20 rotates in the first rotation slot 111, The first rotary shaft 211 simultaneously the most not affecting compartment 20 opposite side departs from the first rotation slot 111 of opposite side.

As it is shown on figure 3, the tilting procedure of this reversible self-discharging semitrailer is: two support bars 32 of the same side, compartment 20 by Gradually extend, the support bar 32 of side, compartment 20 around bearing pin 311 according to compartment 20 rotation direction rotate and support bar 32 gradually Stretching out from urceolus 33, the first rotary shaft 211 of side, compartment 20 progressively disengages the first rotation slot 111, compartment 20 opposite side respectively The first rotary shaft 211 be in the first rotation slot 111 in rotate, in the support bar 32 of compartment 20 opposite side is contracted in urceolus 33 and Rotate around bearing pin 312 according to compartment 20 rotation direction.

In sum, the technical solution of the utility model sufficiently effective can realize above-mentioned utility model purpose, and this Structure and the principle of work and power of utility model are the most sufficiently verified, can reach intended effect and mesh , on the premise of without departing substantially from principle of the present utility model and essence, the embodiment of utility model can be made numerous variations Or amendment.Therefore, this utility model include all be previously mentioned in patent claim in the range of all replacement contents, any The equivalence change made in this utility model claim, within all belonging to the scope of the claims of this case application.
