Abstract
The utility model relates to vehicle equipment, in particular to a flat-bed trailer with a foldable gooseneck. The flat-bed trailer comprises a main vehicle frame, wherein the main vehicle frame is connected with a traction frame through a connecting rod mechanism, and a hydraulic oil cylinder is connected between the connecting rod mechanism and the main vehicle frame. The main vehicle frame and the traction frame are in separated structures, the main vehicle frame is hinged with the traction frame through the connecting rod mechanism, at the same time, the hydraulic oil cylinder is added between the connecting rod mechanism and the main vehicle frame, and the traction frame is stretched and folded to move in a gooseneck mode through lifting and contraction of the hydraulic oil cylinder. Therefore, the bearing height of the traction frame is changed to be matched with different main machines. Adaptability of the vehicle equipment is improved, transportation is convenient, and use cost is saved.
Description
Technical field
The utility model relates to vehicle arrangement, particularly the folding open trailer of a kind of gooseneck.
Background technology
At present, most construction machinery and equipment and equipment transport by flat truck, because the tractor truck saddle bearing height that each main engine plants of China produce is disunity all, cause between trailer and the different main frame and can not mutually mate, in order to transport certain construction machinery and equipment and equipment, just need to again buy tractor truck and trailer, service efficiency is low to have caused great waste, has also caused huge economic loss to the user.
The utility model content
The purpose of this utility model is to provide good, the easy to use gooseneck of a kind of commonality folding open trailer.
The technical scheme that its technical matters that solves the utility model adopts is:
The folding open trailer of a kind of gooseneck comprises main car frame, and described main car frame is connected with drawbar frame by connecting rod mechanism, is connected with hydraulic ram between connecting rod mechanism and the main car frame.
Described connecting rod mechanism one end and drawbar frame are hinged, and the other end and main car frame are hinged.
Described hydraulic ram one end and connecting rod mechanism are hinged, and the other end and main car frame are hinged.
Main car frame of the present utility model and drawbar frame are split-type structural, hinged by connecting rod mechanism between main car frame and the drawbar frame, between connecting rod mechanism and main car frame, add hydraulic ram simultaneously, by lifting and the contraction of hydraulic ram, reach the stretching, extension of drawbar frame and fold the motion of shape such as gooseneck.Thereby change the height that holds of drawbar frame, can from different host matchings.Improve the comformability of vehicle arrangement, not only made things convenient for transportation, also saved use cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is working state figure of the present utility model;
Fig. 3 is A-A cutaway view among Fig. 1.
Among the figure: 1, drawbar frame, 2, connecting rod mechanism, 3, hydraulic ram, 4, main car frame.
The specific embodiment
The folding open trailer of a kind of gooseneck comprises main car frame 4 as shown in the figure, and described main car frame 4 is connected with drawbar frame 1 by connecting rod mechanism 2, is connected with hydraulic ram 3 between connecting rod mechanism 2 and the main car frame 4.Described connecting rod mechanism 2 one ends and drawbar frame 1 are hinged, and the other end and main car frame 4 are hinged.Described hydraulic ram 3 one ends and connecting rod mechanism 2 are hinged, and the other end and main car frame 4 are hinged.
During use, hydraulic ram 3 liftings or contraction, control drawbar frame 1 fold or stretches, thus the change drawbar frame hold height, can from different host matchings.
