Description
Technical Field
The utility model relates to a semitrailer technical field specifically indicates a connecting piece is used on low flatbed semitrailer of liftable formula.
Background
The low flatbed semi-trailer is generally used for transporting heavy-duty automobiles, rail vehicles, mining machinery, forestry machinery, engineering machinery and other heavy-duty goods, the lower the gravity center is, the better the stability and safety are, the stronger the capacity of transporting super-high goods and passing overhead obstacles is, but in the transportation operation, due to different road conditions, the whole height is easy to be lower or higher and can not pass through the road surface with obstacles, so the liftable low flatbed semi-trailer is provided, which is composed of a front gooseneck, a bearing frame and a rear gooseneck, one end of the bearing frame is connected with the front gooseneck through a lifting device, the other end of the bearing frame is hinged with the rear gooseneck, the height of the bearing frame is adjusted through the lifting device at one end, in order to keep the level of the bearing frame, an object block is clamped right above the hinged part of the bearing frame and the front gooseneck to compensate the level difference at the two ends of, the bearing frame is close to the hinged shaft end of the bearing frame, and the bearing frame is easy to crack and even break due to large stress, so that the safety performance is greatly reduced, the maintenance is inconvenient, and the transportation cost is increased, and therefore, the improvement is needed.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a stable firm, difficult cracked liftable formula low flat-bed semitrailer and use connecting piece on.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a liftable use connecting piece on formula low flatbed semi-trailer, includes first articulated slab and second articulated slab, first articulated slab is articulated with the second articulated slab, the one end welding of keeping away from its articulated shaft on the first articulated slab bears the frame of low flatbed semi-trailer, the one end welding of keeping away from its articulated shaft on the second articulated slab is on the back gooseneck of low flatbed semi-trailer, first articulated slab comprises first connecting plate and second connecting plate, the one end welding of first connecting plate bears the frame, and its other end has seted up a plurality of spread groove, the one end and the articulated slab of second connecting plate are articulated, and correspond position department integrated into one piece with the spread groove on its other end and have a plurality of connecting block, the connecting block welding is in the spread groove.
The groove depth of the connecting groove is equal to two thirds of the length of the first connecting plate.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model provides a liftable low flatbed with connecting piece on semi-trailer of formula has included first articulated slab, the second articulated slab, bear the frame, the back gooseneck, first connecting plate, the second connecting plate, the spread groove, connecting block etc. first connecting plate is welded respectively in a plurality of spread grooves through a plurality of connecting blocks with the second connecting plate and is formed first connecting plate, can effectively improve the supporting capability of first connecting plate to bearing the frame, greatly reduce first connecting plate and appear the cracked problem even, reduce the cost of transportation, improve transportation safety factor.

As shown in the figure: 1. first articulated slab, 2, second articulated slab, 3, bear frame, 4, back gooseneck, 5, first connecting plate, 6, second connecting plate, 7, connecting groove, 8, connecting block.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-2:
a connecting piece for a liftable low flat-bed semi-trailer is arranged at the rear end of the liftable low flat-bed semi-trailer and comprises a front gooseneck, a bearing frame 3 and a rear gooseneck 4, a lifting device is arranged at the joint of the bearing frame 3 and the front gooseneck, the bearing frame 3 is hinged with the rear gooseneck 4, the connecting piece for the liftable low flat-bed semi-trailer comprises a first hinged plate 1 and a second hinged plate 2, the first hinged plate 1 and the lifting device connected with the bearing frame 3 are respectively positioned at two ends of the bearing frame 3 and play a role of supporting the bearing frame 3, the first hinged plate 1 is hinged with the second hinged plate 2, one end, far away from a hinged shaft, of the first hinged plate 1 is welded on the bearing frame 3 of the low flat-bed semi-trailer, one end, far away from the hinged shaft, of the second hinged plate 2 is welded on the rear gooseneck 4 of the low flat-bed semi-trailer, the first hinged plate 1 comprises, the one end welding of first connecting plate 5 is on bearing frame 3, and its other end has seted up a plurality of spread groove 7, the one end and the second articulated slab 2 of second connecting plate 6 are articulated, and have a plurality of connecting block 8 with spread groove 7 corresponding position department integrated into one piece on its other end, connecting block 8 welds in spread groove 7, and the laminating of connecting block 8 is in spread groove 7, and first connecting plate 5 is at the first articulated slab 1 of constitution with 6 parallel and level of second connecting plate after the welding, and the welding of a plurality of connecting block 8 one by one is in a plurality of spread grooves 7, and this kind of structure can strengthen first articulated slab 1 greatly to the support ability who bears frame 3, greatly reduces the cracked problem of appearing on the first articulated slab 1 even, and is preferred, the groove depth of spread groove 7 equals two-thirds of 5 length of first connecting plate, guarantees the support ability of first articulated slab 1.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
