Abstract

The utility model relates to a three-axle flat-bed semi-trailer. The semi-trailer comprises a gooseneck high board, a platform low board and a tail board, wherein the gooseneck high board is connected with the platform low board connected with the tail board, a traction pin is arranged between the gooseneck high board and the platform low board, axles are arranged at the lower end of the tail board and fixed on a connecting shaft through a frame rail, and a guide bridge is arranged and fixed at the tail of the tail board through a spindle. The three-axle flat-bed semi-trailer is simple in structure, reasonable in design, convenient to use, high in safety factor, high in stability, and capable of effectively keeping the gravity center in a relatively appropriate position and running on uneven road surfaces.

Description

A kind of three axle flat platform semitraileies

Technical field

The utility model relates to the superimposed trailer that a kind of over-the-road transportation is used, and relates in particular to a kind of three axle flat platform semitraileies.

Background technology

As everyone knows, low flat bed semi trailer is commonly used to transport heavy motor vehicle (as tractor truck, motorcoach, special-use vehicle etc.), guideway vehicle, mine equipment, forestry machinery, construction machinery and equipment (as excavating machine, bulldozer, loader, paver, hoisting crane etc.) and other heavily loaded goods, its center of gravity is lower, stability and safety are better, transportation overheight cargo and just stronger by the ability of crown obstacle.Low flat bed semi trailer adopts tenon riveting (or well type) vehicle frame conventionally, both front section of vehicle frame was that (towing pin of gooseneck leading portion is connected with the traction saddle on tractor truck gooseneck, gooseneck rear end is connected with semi-trailing car frame), stage casing is goods platform (vehicle frame lowermost portion), rear end is wheel carrier (containing wheel).

When loading machine equipment on low flat bed semi trailer, normally from semitrailer rear end loading machine equipment, the mode that adopts above rear wheel frame mechanically moving equipment or wheel is removed, and then mechanical equipment is fixed on superimposed trailer.

Existing low flat bed semi trailer, in the process of travelling, because center of gravity is too low, when travelling the rugged road in some road surfaces, is difficult for travelling, and easily causes the accident, and safety factor reduces.

Utility model content

The purpose of this utility model is: for defect and the deficiency of prior art, provide a kind of simple in structure, a kind of three axle flat platform semitraileies reasonable in design, easy to use, not only can keep center of gravity in a relatively suitable position by actv., and can travel on the road surface of road injustice, its safety factor is high, and stability is strong.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of three axle flat platform semitraileies described in the utility model, comprise the high plate of gooseneck, the low plate of goods platform and tailgate, the high plate of gooseneck is connected with the low plate of goods platform, the low plate of goods platform is connected with tailgate, wherein, between the high plate of gooseneck and the low plate of goods platform, is provided with towing pin, the lower end of tailgate is provided with axletree, axletree is fixed on adapter shaft by chassis side rail, and the afterbody of tailgate is provided with access bridge, and access bridge is fixed on the afterbody of tailgate by rotating shaft.

In the utility model: be also provided with reduction pull bar on described tailgate, one end of reduction pull bar is fixed on tailgate, and the other end is connected with access bridge.

In the utility model: the number of described axletree is 3 pairs, and wherein axletree and adapter shaft support the use.

Adopt after said structure, the utility model beneficial effect is: the utility model is simple in structure, reasonable in design, easy to use, not only can keep center of gravity in a relatively suitable position by actv., and can travel on the road surface of road injustice, its safety factor is high, and stability is strong.
