Furthermore, the supporting device is composed of two supporting rods, the left ends of the outer side faces of the two supporting rods are welded together through steel plates, the distance between the two supporting rods is larger than the width of the hydraulic oil cylinder, and after the supporting device is lifted, the hydraulic oil cylinder can be hidden between the two supporting rods, so that space is saved, and the hydraulic oil cylinder can be protected.
Furthermore, the right end of the outer side surface of the supporting device is provided with a bearing wheel.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the semitrailer frame traction gooseneck supporting device is simple in design and structure, achieves lifting by means of a hydraulic device, and can automatically adjust the semitrailer to pull the gooseneck to lift so that the gooseneck is separated from a traction headstock; the working process is convenient and reliable, time and labor are saved, external force assistance is not needed in single-person operation, and the traction vehicle head and the semi-trailer can be quickly mounted or separated;
2. the supporting device can be opened with higher speed by controlling the extension of the hinged seat of the hydraulic oil cylinder, the semi-trailer can be supported by the supporting device to pull the gooseneck, the L-shaped protection plate can play a good protection role on the hydraulic oil cylinder control device, and the bearing wheels are arranged to facilitate the jacking of the trailer for pulling the gooseneck.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a front view of the present invention;
fig. 3 is a top view of the present invention.
In the figure: the device comprises a supporting device 1, a supporting seat 2, a hydraulic oil cylinder hinged seat 3, a hydraulic oil cylinder 4, a hydraulic oil cylinder control device 5, a semitrailer traction gooseneck 6, a traction pin 7, an 8L-shaped protection plate and a bearing wheel 9.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
