Description
Technical field
The utility model is related to a kind of groined types to combine pallet inset type vehicle frame.
Background technology
Currently, the variation of conveying semi-trailer in the market with the main management philosophy of transport service, vehicle needs light weight, bending resistance,
Bearing capacity is strong, structure is beautiful easy-maintaining, but because of technical-constructive design difference, the vehicle of conventional structure design steel transportation,
Column position occur collapsing waist phenomenon, the tail portion tower buttocks of standing between third breast board of preceding second of vehicle frame is existing when the substances such as marble, roll paper
As, it is wavy after vehicle loading obviously to influence aesthetics, because the waist that collapses, buttocks problem of collapsing cause vehicle in the reality of equally loading rear vehicle
Difference occurs for border centroid position and vehicle axle load, or even grinds tire in causing vehicle to run, gnaws the generation of tire phenomenon, or even goes out current situation
Portion's structural member cracking phenomena and so that bearing capacity is had a greatly reduced quality, give vehicle safety, service life period and operation cost
Cause different degrees of puzzlement.And safety that these are advocated with society, saving, durable, handy, matched vehicle demand are managed
Thought is disagreed.
Utility model content
The purpose of this utility model is to overcome the above deficiencies, develop a kind of groined type combination pallet of the utility model
Inset type vehicle frame, technical problems to be solved are：Built-in groined type soldering pallet is set by vehicle frame gooseneck variable cross-section section to increase
Its strong bending resistance and bearing capacity, solve the problems, such as neck, tail position because of the waist that occurs collapsing after device substance, collapse buttocks, while by big
Anti-crawl agentdefiection problem is carried in the middle part of the reversible deformation compensation vehicle of beam, has good straightness or camber after so that vehicle frame is loaded cargo,
To achieve the goals above, the technical solution of the utility model is：
A kind of groined type combination pallet inset type vehicle frame, including crossbeam, it is characterized in that：Middle cross beam is provided between crossbeam,
It is additionally provided with side bar on the outside of crossbeam, side crossbeam is provided between crossbeam and side bar, the front and back side of crossbeam is provided with front beam with after
End carriage, two crossbeam necks insides are provided with well shape pallet, and well shape pallet includes that flute profile longeron and middle cross beam are composed, flute profile
Longeron is provided with perforation, and middle cross beam is connect by perforating with flute profile longeron.
The groove-shaped longitudinal beam top surface of the well shape pallet and big top surface of the beam are in the same plane.
Several flange circular holes are provided in the middle part of the crossbeam, tail portion is arc-shaped to upwarp structure, and crossbeam includes web, thereon
Side is upper flange, and downside is lower wing plate, and reinforcement batter post is additionally provided between crossbeam and side crossbeam.
The middle cross beam and side crossbeam is breakaway-element structure, and side crossbeam and middle cross beam are equipped with lightening hole.
The groove-shaped longitudinal beam rear end lower connects diagonal brace with reinforcement is provided with, and the notch of groove-shaped longitudinal beam is in opposite directions and between reservation
Away from.
Multigroup conjunction groined type tray frame is connected in by the whole crossbeam of two whole longerons of clod wash groove profile and five or so are pre-splicing
Assembly is for use, by several punching crossbeams and piercing and flanging crossbeam, side bar and aforementioned groined type tray frame assembly by tooling
It is vehicle frame that mould, which splices soldering, two longeron rear lower of pallet be arranged reinforce connection diagonal brace so as to will in pallet and clod wash thereafter it is horizontal
Beam soldering is integrated, and two groove-shaped longitudinal beam top surface of pallet in the same plane, then on the vehicle frame is welded with longitudinal beam top surface
The attachmentes such as draft gear and draft hitch constitute the frame assembly of semitrailer.The utility model has the beneficial effects that passing through vehicle frame
The built-in groined type bending resistance of neck setting, antitorque pallet make the neck weak link intensity of vehicle frame and bending flexibility greatly increase, and carry
High resistance to deformation characteristic of the vehicle frame when loading special cargo, makes each axle load be distributed in scope of design, enhances vehicle and fill
Aesthetics after loading object extends the service life period of vehicle, reduces the maintenance operation cost of user, passes through crossbeam tail
Structure design is received in portion makes tail portion stress decompose oblique Forward and reduce the buttocks problem of collapsing that big beam rear part bending generates, and makes vehicle
It is more preferable to use.The structure design is ensureing front rigidity and transverse property, can effectively reduce crossbeam neck profile height,
The loading end height of vehicle is set to accomplish traveling that is minimum, and enhancing vehicle the case where faying face height is installed in traction of the same race
Stability and safety.Its structure adds breakaway-element beam structure to make with respect to neck using side plate reinforcement and three I-shaped longerons
Technique is simpler, it is less to be more easy to streamlined operation, production efficiency higher, crossbeam specification, cost is lower, conducts oneself with dignity lighter, intensity more
It is high.
