Description
Technical field
The present invention relates to have the trailer of springboard, especially relevant with a kind of trailer segment type springboard.
Background technology
The segment type springboard of existing trailer comprises the two springboard bodies that are divided into about the trailer afterbody, as Fig. 1, Fig. 2 and shown in Figure 3, each springboard body comprises the first segment body 10 and the second abridged edition body 20, first segment body 10 is articulated in the springboard permanent seat 11 of trailer afterbody 4 by first articulated section 12, and the first segment body adopts hydraulic actuator 5 to drive its liftings; The second abridged edition body 20 is articulated in first segment body 10 by second articulated section 15, adopts to move manually to make its expansion; After big machinery is climbed up, operating hydraulically operated power element 6 drives first segment body 10 and rises, the second abridged edition body 20 is along with rise, but at this moment because just simply hinged between the first segment body 10 and the second abridged edition body 20, in the process of the second abridged edition body, 20 closures, first segment body 10 is formed a kind of collision easily, can cause certain damage, obviously first segment body 10, this operating mode was both time-consuming, and labour intensity is big again.For the labor content that reduces the personnel to operate, raise the efficiency, need that design is a kind of to make that the second abridged edition body 20 can launch automatically with 10 liftings of first segment body, the mechanism of closure.
As shown in Figure 3, in the process that first segment body 10 descends, must be that technician's M/C second abridged edition body 20 is arranged, make its angle that descends by first segment body 10, and the angle between the two joint springboards is progressively increased, after the angle between the two joint springboards is greater than 90 degree, the second joint springboard is under the situation that first segment body springboard promotes, make 20 one-tenth 180 degree of the first segment body 10 and second abridged edition body angle, obviously, operation is relatively wasted time and energy like this.
Summary of the invention
At problems of the prior art, the objective of the invention is to reduce the labor content of operating personal, raise the efficiency, provide a kind of make the second abridged edition body can with the first segment body rise and fall and automatically launch, slow closed mechanism, thereby the second abridged edition body is to the impact of first segment body when avoiding closure.Another object of the present invention is to provide a kind of trailer with this segment type springboard, the slow closure that realizes the automatic expansion of trailer springboard and prevent to collide.
For achieving the above object, as follows in technical scheme of the present invention, a kind of trailer segment type springboard, comprise the two springboard bodies that are divided into about the trailer afterbody, each springboard body comprise the first segment body that is articulated in described trailer afterbody, with the first segment body pivotally attached second abridged edition body, and drive the power element that the first segment body rises and falls, described springboard body side is provided with the automatic developing machine structure, comprising:
Push rod, an end is articulated in the trailer afterbody;
The holder part, its recess is the supporting part, and described holder part is by described push rod push-and-pull, and described holder part central part is articulated in the described push rod other end, and the other end is articulated in first segment body front end side; When described power element drove described first segment body and rises and falls, described holder part can rotate around the jointed shaft on the first segment body;
By supporting parts, be fixedly arranged on the end side surface of the described second abridged edition body near the first segment body, thereby can be promoted to make the second abridged edition body rotary expansion by the supporting part of described holder part during rise, thereby can be made the second abridged edition body slowly closed by the supporting part support of described holder part when falling.
A kind of trailer comprises vehicle frame, and described vehicle frame afterbody is provided with springboard, and described springboard is a trailer segment type springboard of the present invention.
Trailer of the present invention, wherein, described trailer afterbody is provided with the accessory plate that described trailer tail down is widened, and described accessory plate rear is provided with the reinforced plate of reinforcing described accessory plate.
Trailer of the present invention, wherein, described automatic developing machine structure is arranged at the relative inner of the described first springboard body and the second springboard body.
Beneficial effect of the present invention is: trailer of the present invention and trailer segment type springboard, operate easier, safer, time saving and energy saving; The automatic expansion that has realized springboard is saved manpower with closed.By segment type springboard of the present invention, make of the decline of the second abridged edition body along with first segment body springboard,, and realize the automatic stretching, extension of trailer springboard saving springboards in line to by the guiding of supporting parts and support effect by the holder part up to two; Otherwise when first segment body springboard rises, the second joint springboard is under the effect of trailer segment type springboard, slowly with first segment body springboard closure, and can not form impact, reduce simultaneously because the noise of bump and the generation of jointed shaft twirl to first segment body springboard.Improve mechanical loading efficient, improved economic benefit.
