Description
Technical field
This utility model relates to frame for movement technical field, especially relates to a kind of triangle tube structure containment type node list
Main beam structure.
Background technology
Container Transport originates from Britain in 19 beginnings of the century, formal extensively uses from early in the twentieth century starting to obtain.Nearly ten
In the past few years along with World Economics total amount increase, international trade develop rapidly, world's cargoes imported and exported with annual 70% speed
Increasing, world commerce great development promotes the fast development of Container Transport industry.Along with the development of Container Transport industry, how to seek
The approach expanding its handling capacity is asked to be worth us to go to consider.To this end, in addition to the maximization of container ship, also an urgent demand
The maximization of container crane and high efficiency.But they have to reduce again the wheel load acting on track, therefore container
Crane is necessary for wanting lightweight.
Container crane realizes the light-weighted main beam structure lightweight that it is critical only that crane.Existing great majority rise
The main beam structure of heavy-duty machine is more complicated, discontinuity, is particularly affected bigger by wind load, uses in strong wind atmosphere
Being greatly affected, existing girder construction connects insecure, is susceptible to fracture.
Summary of the invention
The purpose of this utility model be contemplated to solve the problems referred to above and a kind of simple in construction is provided, lightweight, stress is equal
The triangle tube structure containment type node list main beam structure that even, reliability is high.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of triangle tube structure containment type node list main beam structure, including three main chord tubes, some web members and containment type
Node, described main chord tube and web member are consolidated by described containment type node, form the truss structure of spatial triangle section.
Three main chord tubes form equilateral triangle structure by the connection of web member, and described web member consists of containment type node
Triangular section structure.
On two main chord tubes equipped with dolly slide track, the 3rd main chord tube is welded with container crane before and after
The joint that pull bar and mast connect.
Described containment type node is fixed by welding on described main chord tube.
Described containment type node is provided with web member hole, and the web member hole of containment type node is inserted at the two ends of described web member, logical
Cross scrap (bridge) circumference soldering to consolidate with containment type node.
Angle between adjacent web members is 46-55 °.
Described containment type node is prepared by 8000 tons of friction presses and containment type node mould forging forming.
Compared with prior art, this utility model has the advantage that
1, three main chord tubes and web member are got up by containment type node consolidation, form the truss knot of spatial triangle section
Structure, truss itself is lighter 25-30% than box, it is ensured that the stable and lightweight of structure；
2, containment type node passes through 8000 tons of friction presses and containment type node mould forging forming, makes fatigue stress drop
Low 3 times, it is greatly prolonged the life-span of truss, fundamentally solves node and be difficult to make, anti-fatigue ability is poor, easy to crack etc. asks
Topic, uses firmly, does not ftractures；
3, containment type node realizes being reliably connected with main chord tube and web member by welding, direct relative to main chord tube and web member
Connecting, be greatly improved the reliability and stability of junction, the stress raisers the most significantly reducing junction are existing
As；
4, the horizontal wind area of this list girder space truss type structure reduces about 20% than box-structure, corresponding wind load
Lotus is substantially reduced.
This utility model uses this kind of single girder space truss type structure to replace traditional box beam supporting construction, makes lifting
Machine quality is greatly reduced so that crane support support reaction alleviates, reduce drive motor power, saves energy, especially
Being to act on while the wheel pressure on the basis of harbour bank is greatly reduced, the wind load being subject on overhanging beam also subtracts
Little.This utility model has simple in construction, lightweight, uniform force, high reliability, is suitable as harbour container
The overhanging crossbeam of crane, could be used that in strong wind atmosphere.
Accompanying drawing explanation
Fig. 1 is assembling structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model containment type node；
Fig. 3 is the installation diagram structural representation of this utility model containment type node；
In figure: 1-main chord tube, 2-web member, 3-containment type node.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1
A kind of triangle tube structure containment type node list main beam structure, Fig. 1 is assembling structural representation, including three main strings
Pipe 1, some web members 2 and some containment type nodes 3, main chord tube 1 and web member 2 are consolidated by containment type node 3, form space triangular
The truss structure of shape section, three main chord tubes 1 form triangular structure by the connection of web member 2, and web member 2 is by containment type node
3 composition triangular section structures.During use, two main chord tubes below are also equipped with the track that dolly slides, above
The joint being connected with pull bar before and after container crane and mast it is welded with on main chord tube.
Owing to triangle has good stability, therefore this utility model takes triangular section structure whole to ensure
The stability of girder.The diameter of three main chord tubes 1 is 402mm, and wall thickness is 12mm, the material selection good welding performance of main chord tube
Hi-Stren steel, in space become equilateral triangle arrange, on three strings pipe every 3300mm be welded with for combine bag
Appearance formula node 3；Web member 2 forms triangular section structure by containment type node 3, and a diameter of 159mm selected by web member, and wall thickness is
The Hi-Stren steel of 10mm, two is welded on containment type node at the circular hole cut out.
Fig. 2 is the structural representation of containment type node, a length of 900mm of containment type node 3, and wall thickness is 14mm, uses
8000 tons of friction presses and corresponding containment type node mould forging forming, elect Q345 structural section as, and containment type node 3 is through forging
After causing semi-finished product, then it is processed, opens 4 web member holes after sand washing, and be welded on truss structure main chord tube 1.Due to forging
The defect such as loose that can eliminate that metal produces in smelting process, optimizes heterogeneous microstructure, simultaneously because save complete
Metal streamline, the mechanical performance of forging generally to be preferred over the foundry goods of same material, forging forming, and cost is relatively low, power levelling at node
With, fatigue stress concentration factor is little, and the weld seam that containment type node 3 is on main chord 1 is long, and bonding strength is good.
Fig. 3 is the installation diagram structural representation of containment type node, and web member 2 and main chord tube 1 are connected by containment type node 3,
Web member 1 is fixedly arranged at containment type node 3 upper abdomen rod aperture by scrap (bridge) circumference soldering, becomes 46 ° or 54.7 ° between adjacent web member
Angle, the inclusion cavity of containment type node is up to 900mm, improves the rigidity of whole truss, and web member inserts and contains in node
Portion, it is to avoid conventional node is only welded in the Z-direction stress that main chord surface produces.
This beam has simple in construction, lightweight, uniform force, high reliability, is suitable as harbour container and rises
The overhanging crossbeam of heavy-duty machine, could be used that in strong wind atmosphere.
