Abstract
The utility model discloses a gooseneck device of a lifting semi-trailer, comprising a gooseneck frame, a traction-pin panel and a hydraulic cylinder; wherein, the upper end of the hydraulic cylinder is vertically fixed on the foreside of the gooseneck frame while the lower end is fixed on the traction-pin panel inside the gooseneck frame; the gooseneck frame is connected with the rear end of the traction-pin panel via the rotating shaft; and a stable block is respectively positioned on two lateral faces of the foreside of the traction-pin panel. The utility model has the advantages of simple structure, low manufacturing cost and capability of adjusting the height of the routine semi-trailer cargo table.
Description
Technical field
The utility model relates to the hydro-mechanical unit of the dull and stereotyped goods platform of adjustable semitrailer level.
Background technology
In the middle of transportation, people use superimposed trailer through regular meeting, and when using superimposed trailer, generally all need to adopt lifting gooseneck device to adjust goods platform level, especially transport overheight cargo.The lifting gooseneck that current people use all with bottom (goods platform front end) after the gooseneck main body as center of turn, adopt after pad compressing cylinder or upper liquid compressing cylinder, realize that by the pushing tow of hydraulic ram gooseneck moves up and down in overall.This type of device has complex structure, and manufacturing cost is high and from defective such as great.
The patent No. 03252092.1 discloses a kind of hydraulic pressure gooseneck device of super deep-loading semitrailer, belongs to a kind of hydraulic machinery, instigates especially to be used on the semi-mounted lorry.Its gooseneck boom is anterior captives joint with the gooseneck boom main part, dynamic device in the gooseneck boom front portion, captive joint single cylinder oil cylinder in the gooseneck boom main part, pole on the oil cylinder is connected with swinging mounting block top, the semi-mounted axletree of swinging mounting block bottom and gooseneck boom main part below is rotationally connected, and the gooseneck boom elevation angle limits support plate and the gooseneck boom main part flexibly connects.This gooseneck and difference of the present utility model are: this gooseneck device hydraulic ram level is installed in the gooseneck front portion, and the axle center is installed in the gooseneck rear lower, and structure is complicated.
Summary of the invention
The utility model provides that a kind of lifting semitrailer is simple in structure, the gooseneck device of low cost of manufacture.
A kind of gooseneck device of lifting semitrailer, comprise gooseneck boom, towing pin panel and hydraulic ram, the hydraulic ram upper end is vertically fixed on the gooseneck boom front portion, the lower end is fixed on the towing pin panel of gooseneck boom inboard, the rear end of towing pin panel is connected with gooseneck boom by rotating shaft, and two sides of towing pin panel front portion respectively are provided with a stable piece.The towing pin panel with gooseneck rear portion top as center of rotation.Hydraulic ram can be one, also can symmetrical two of installing.
When hydraulic ram extended, the towing pin panel moved downward, and gooseneck boom rises thereby drive on the flat truck goods platform plane relatively to rising; Otherwise then descend.The lifting of hydraulic ram can realize with manual hydraulic oil pump or electric hydaulic oil pump.
The utility model is provided with the height adjustment that hydraulic ram is realized conventional superimposed trailer goods platform by the front end at the gooseneck device, and is simple in structure, weight reduction, low cost of manufacture.The utility model operating process is simple, has improved the safety and the work efficiency of driving vehicle widely.

Fig. 5 is a gooseneck boom shown in Figure 4 left TV structure scheme drawing when raising.
The specific embodiment
As Figure 1-3, the utility model is a kind of lifting semitrailer gooseneck device, comprises gooseneck boom 1, the inboard towing pin panel 2 of gooseneck boom and hydraulic ram 3.Hydraulic ram 3 vertical summetry are installed in gooseneck boom 1 front part sides, hydraulic ram 3 lower ends are fixed on the towing pin panel 2, towing pin panel 2 rear ends are connected with gooseneck boom 1 by turning cylinder 4, side, towing pin panel 2 the place ahead respectively is provided with a stable piece 5, has guaranteed the stability of gooseneck in transportation like this.
The utility model is finished the gooseneck lifting process shown in Figure 4 and 5: at first, 3 elongations of hydraulically extensible oil cylinder, with towing pin panel 2 top to gooseneck boom 1 angled position, thereby promote the height of gooseneck boom 1 by the rotation in axle center 4, gooseneck boom 1 rises to drive again on the flat truck goods platform plane and rises, increase the flat truck ground Clearance, improve the crossing ability of vehicle; Otherwise then descend.
