Description
Technical field
The utility model belongs to vehicle safety equipment, is especially a kind of semitrailer packaged type rear.
Background technology
Rear belongs to semitrailer car out protecting device, and main function is to stop car rear-end semitrailer with laggard one
Step pierces the rear portion of semitrailer.Rear can absorb local collision energy, and protection flight deck crew safety, mitigates vehicle
Damage, therefore national Specification semitrailer must install rear.
The rear used on the semitrailer travelled on Current Highway substantially uses stationary structure, itself and vehicle frame
Rigid connection, maximum terrain clearance are determined by national standard.Since actual road conditions are complicated, when Uneven road or descending, keeps this most
Big terrain clearance may cause rear to be collided with ground, influence semitrailer safety.For some Special use operating modes, such as
Carry on the back unlucky defeated, semitrailer needs to reach railway and carries back of the body flat car for transportation on the back, and the rear of semitrailer can be carried on the back unlucky defeated flat with railway
Car interferes, and is unfavorable for the utilization that railway carries back of the body flat car for transportation space on the back, need to adjust rear protecting height.
Utility model content
It is difficult to meet full working scope demand, and the prior art to solve existing semitrailer rear maximum terrain clearance

Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples, those skilled in the art should know
Road, following embodiments are not the unique restriction made to technical solutions of the utility model, every in technical solutions of the utility model
Any equivalents done under Spirit Essence or change, are regarded as belonging to the scope of protection of the utility model.
Referring to Fig. 1, a kind of semitrailer packaged type rear, including lower protective fence 1, rotating bar 2, rotational positioning dress
Put 4, fixed plate 5, axis pin 6, supporting rod 7 and clip 8.
Rotating bar 2 has two, and symmetry is arranged on the both sides of semi-trailer frame 3, and two rotating bars 2 are arranged in parallel, one end
Respectively it is flexibly connected with a rotary positioning apparatus being fixed on vehicle frame 34, the other end is fixedly connected with lower protective fence 1 jointly, is made
Lower protective fence 1 remains horizontal position.Fixed plate 5 is fixed on vehicle frame 3, and 7 one end of supporting rod is connected by axis pin 6 and fixed plate 5
Connect, the other end is connected by the clip 8 on supporting rod with rotating bar 2.
Rotating bar 2 is installed on can be rotated on rotary positioning apparatus 4, so as depicted in figs. 1 and 2, rotating bar 2 can be with
Lift or put down；And since in rotary course, the restriction effect of supporting rod 7 and clip 8, rotating bar 2 rotates against positioning
Device 4 can be to slip at headstock or the tailstock.
Spacing, the rotation position of limitation rotating bar 2 is set in rear.It is possible to further be set on vehicle frame 3
It is spacing, the limited post (9) of plug such as can be shifted, limit the highest order and lowest order of rotating bar 2, rotating bar 2 rotates to a positioning
Put and just stop, horizontal level as shown in Figure 2, rotating bar 2 is maintained at the position and no longer moves, spacing while sustainable firmly rotation
Bar keeps ground clearance.
Preferably, limit rotating bar 2 it is rotating it is spacing may also be arranged on rotary positioning apparatus 4, rotary positioning apparatus 4
As shown in Figure 3, Figure 4, whole rotary positioning apparatus is by spacing collar 41, rotation axis 42, limit button 43, elastic spacing piece for structure
44 are formed.Card slot 411 is provided with 41 side wall of spacing collar, the insertion for elastic spacing piece 44；One of spacing collar 41
End face is welded on vehicle frame, and the other end is open, can load rotation axis 42 in cylinder.
Rotation axis 42 is hollow, and inside sets elastic spacing piece 44, is stretched as shown in figure 5, being carried on elastic spacing piece 44
The long wing 441, the elongation wing are pierced by rotation axis 42, are inserted into card slot 411 or pull out；It is possible to further extend
Tip extension thickeies or increase limited block 442, easy to be stuck in card slot 411.
Limit button 43 penetrates outside rotation axis 42, is arranged on the top of elastic spacing piece 44, and 42 madial wall of rotation axis has
Vertical slots, limit button 43 are slidably installed in vertical slots, itself can free vertical and straight movement, and rotation axis can be driven in circumferential direction
42 rotate together.
The wing 441 is extended when spacing, when spacing to be stuck in card slot 411, when firmly pressing limit button 43 downwards, is pushed
44 center of elastic spacing piece, moves down elastic spacing piece 44 while micro-deformation occurs, and the elongation wing 441 is retracted into sleeve；Pine
After opening limit button 43, elastic spacing piece 44 is upspring, and the elongation wing 441 flexes outward upwards, and snaps into card slot 411.Rotating bar 2
It is threaded through on limit button 43, when rotary positioning apparatus 4 is not in spacing, rotary motion bar 2 can drive rotation axis 42 to rotate.
Further, spring can be set in 44 bottom of elastic spacing piece, aids in it to upspring.
Further, rotary positioning apparatus 4 can be set multiple spacing as desired, card slot 410 and elongation 441 quantity of the wing
Corresponding with distribution angle, the quantity of setting is unrestricted, spacing accurate if what is set is some more.
Further, square steel or round steel can be selected in above-mentioned rotating bar 2 and lower 1 material of protective fence, and clip 8 is square or circle
Shape.
On the other hand, rotating bar 2 is sleeved on clip 8, is connected with supporting rod 7, is manually operable clip and is loosened or tighten.
As shown in Figure 1, under inactive state (normal road surface), rotary positioning apparatus 4 is in spacing state, and rotating bar 2 is locked
Fixed, supporting rod 7 is horizontal, and slightly diagonally downward, clip 8 applies a pulling force to rotating bar 2 to rotating bar 2, prevent its from
Rotate counterclockwise, it is impossible to moved to headstock, the height of rear meets national standard requirement for height.
As shown in Fig. 2, under use state (roughness pavement), releasing rotary positioning apparatus 4 is spacing, unclamps clip 8, rotates
Bar 2 is rotatable, and rotating bar 2 stops when lifting to certain altitude (reaching horizontal) position, and rotating bar 2 is promoted to headstock direction, is reached
To extreme position, relock；Also reach spacing between supporting rod 7 and axis pin 6 at this time, give rotating bar 2 one support forces, rear protecting
Device is static, semitrailer can Uneven road or descending state downward driving or participate in carrying on the back it is unlucky defeated, reach railway carry on the back it is unlucky defeated flat
Car.
The utility model has the advantage of：Structure is novel, easy to use, avoids semitrailer in Uneven road or descending
Rear and collision on the ground, and carry on the back it is unlucky it is defeated during semitrailer reach railway carry back of the body flat car for transportation on the back and the structure that occurs
Interference, ensure that semitrailer driving safety, be conducive to semitrailer participate in carry on the back it is unlucky defeated.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.
