Description
One, technical field
The utility model relates to a kind of transportation means, particularly relates to a kind of intensity height, durable, lightweight grooved longeron superimposed trailer.
Two, background technology
Along with the swift and violent development of China's economy, the adjustment of national automobile industry and steel industry policy, China's special vehicle industry is in industrial upgrading, products perfection stage.At present, the self-discharging semitrailer that China produces adopts general steel plate and common welding i-shape steel beam more, this special-use vehicle structure, exist shortcomings such as curb mass is overweight, load carrying ability is low, energy consumption is big, and vehicle exposes for a long time, automobile-used boxboard and skeleton corrosion stability are low, cause in a large number corrosion just now, and the vehicle operation life-span is also very short.
Particularly longeron is as the main load bearing component and the structure member of vehicle frame, in the travelling of automobile, bear bigger flexure stress, but the tradition welding i shaped steels that adopt more, the welding i shaped steel, it exists, and how stressed irregular, the unrelieved stress of soldered is big, cutting and welding process complexity, the very big shortcoming of conducting oneself with dignity.
Three, utility model content
The purpose of this utility model provide a kind of simple in structure, be convenient to process, durable, from the grooved longeron superimposed trailer of heavy and light.
The technical solution of the utility model is: a kind of grooved longeron superimposed trailer, contain car body, vehicle frame is installed below the car body, vehicle frame contains longeron, and at least two row's wheels are installed below vehicle frame is latter half of, supporting leg, towing pin is installed below the vehicle frame forebody, described compartment comprises column and boxboard, the longeron of described vehicle frame is the trough girder of steel plate bending and forming, and this trough girder contains upper flange, web and lower wing plate, and its upper and lower wing plate vertically is connected with web.
The web width of the forebody of described longeron is less than the rear portion web width.
The upper flange width of described longeron is less than lower wing plate.
Described vehicle frame both sides are equipped with the side protective frame between supporting leg and wheel, described vehicle frame both sides are equipped with side lamp.
Described longeron is the grooved crossbeam that the bending of high-strength and high-weather-resistance steel plate forms.This high weather resistance steel plate trade mark is Q700NQ, and by Baosteel production, its yield strength has reached more than 700 MPas, and atmosphere corrosion resistant performance height, can expose use.
The beneficial effects of the utility model
1, simple in structure, be convenient to processing, process velocity is fast
The longeron of the grooved longeron superimposed trailer in this utility model adopts hot-rolled high-strength weather-resistant steel plate bending and molding, its upper flange, lower wing plate and web are directly for being connected naturally, need not weld, its structure is compared with original I-shape welding longeron, simply many, reduced the processing technology of welding, and process velocity is fast, and can expose and use or the simplification application, reduce coating process.
2, durable
Because the yield strength of the hot-rolled high-strength weather-resistant steel plate of the employing of this grooved longeron reaches more than 700 MPas, the increase of the conventional armor plate strength that intensity ratio is original more than the twice, and this steel grade is antirust, thereby the bulk strength and the service life of this grooved longeron superimposed trailer have been improved, owing to do not have welding process in its processing technology, so just there be not weld seam and the welding stress that forms in the welding, this respect is also having certain effect aspect the whole seed production ability that improves this superimposed trailer.
3, from heavy and light
Because the longeron of the grooved longeron superimposed trailer of this utility model has adopted the hot-rolled high-strength weather-resistant steel plate, its intensity increases, so the vehicle of equal specification is compared it with the superimposed trailer that adopts conventional steel plate to make longeron, the thickness of member is can attenuate many, thus the deadweight that has alleviated this superimposed trailer.
