Abstract

The utility model discloses a door frame for the placement and transportation of ship subsections, including two parallelly standing support columns, a crossbeam is erected between the upper ends of the two support columns, inclined sand sliding boards are respectively arranged at the lower side of the crossbeam and the two sides of the support columns. The door frame provided creates a proper platform for the placement and transportation of the ship subsections, having the characteristics of occupying no ground space during the placement and being safe and reliable during the transportation.

Description

The door frame that boat segmental uses when shelving and transport
Technical field
The utility model relates to a kind of boat segmental after construction finishes, the door frame that boat segmental uses when shelving and transport.
Background technology
Shipbuilding now is to large scale development, the division of segmentation with compared in the past more huge.
Large-scale segmented vessel directly is held on ground usually before waiting for weld-on installation, then be put on the flat truck during transportation and move.
Though this method is simple and easy, there are a lot of weak points::
1. the large ship segmentation is held on the ground, hinders this regional pedestrian, vehicle pass-through.
2. the large ship segmentation is increasing, directly is positioned on the flat truck, can't guarantee the safety of segmentation in transportation.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that above-mentioned prior art exists; The door frame that provides a kind of boat segmental when shelving and transport, to use; Shelve, transport for boat segmental and create a comparatively suitable platform, make not take ground space when shelving, safe and reliable characteristics during transportation.
The technical solution of the utility model is following:
The door frame that a kind of boat segmental uses when shelving and transport, characteristics are that its formation is the pillar stiffener upper end of a beam erection two parallel settings, is equipped with sliding sand plate in the down either side of described crossbeam and the both sides of pillar stiffener.
A plurality of positions at said crossbeam are provided with Loading Mark, are convenient to discern the different load carrying abilities of door frame diverse location.
The bottom of said pillar stiffener is provided with trapezoidal suspension column, and ground-surface bearing surface is increased.
The height of described pillar stiffener is convenient to the pedestrian and under door frame, is walked greater than 1.8 meters.
The width of the width of described crossbeam and the flat truck of use is suitable.
The use of the utility model is the particular case according to segmented vessel; Adopt the parallel ground that is placed on of a plurality of door frames; On a plurality of door frames, lay the dull and stereotyped platform that constitutes, again in the construction of the enterprising oceangoing ship segmentation of navigating of this platform with shelve, after the segmented vessel construction finishes; When moving this segmented vessel, utilize flat truck to lift described segmented vessel is transported to the destination together with a plurality of door frames.
Compared with prior art the technological merit of the utility model is following:
(1) shelves in the process in segmentation, fill and part utilized the space, make can be under the door frame safe walking of pedestrian.
(2) because the utility model has adopted the gate-type structure, make segmentation that stability relatively preferably arranged in transportation.
(3) owing to below crossbeam, be provided with sliding sand plate, steel ball can be made things convenient for arbitrarily be scattered, avoided the accumulation of steel ball on door frame.

Among the figure: 1-crossbeam, 2-pillar stiffener 3-cunning sand plate 4-Loading Mark 5-suspension column.
The specific embodiment
Please consult Fig. 1 earlier, Fig. 1 is the structural representation of the door frame that when shelving and transport, uses of the utility model boat segmental.Door frame as shown in the figure, that a kind of boat segmental uses when shelving and transport, characteristics are pillar stiffener 2 upper ends that crossbeam 1 is erected at two parallel settings, are equipped with sliding sand plate 3 in described crossbeam 1 down either side and pillar stiffener 2 both sides.A plurality of positions of said crossbeam 1 are provided with Loading Mark 4.
Fig. 2 is the pillar stiffener scheme drawing in the door frame that when shelving and transport, uses of the utility model boat segmental, and as shown in the figure, the bottom of said pillar stiffener 2 is provided with trapezoidal suspension column 5.
Single door frame beam design calculation
1. receive concentrated force P in the girder span
Elastic modulus E=21.4 t/mm 2
Crossbeam moment of inertia I=(300*500 3-280*444 3)/12=1082671040mm 4
Crossbeam calculated length L=6582mm
The beam maximum defluxion promptly calculates concentrated force P allowable down less than the 7mm state less than 1/1000
The beam maximum defluxion occurs in the L/2 place, maximum defluxion V MaxFor:
Figure DEST_PATH_IMAGE001
∴ concentrated force allowable
Figure DEST_PATH_IMAGE002
2. situation when the wide zone of B, beam middle part receives well-distributed pressure Q
The beam two ends support that freely zone line receives well-distributed pressure to see Fig. 3
Elastic modulus E=21.4 t/mm 2
Crossbeam moment of inertia I=(300*500 3-280*444 3)/12=1082671040mm 4
Crossbeam calculated length L=6582mm
The beam maximum defluxion promptly calculates uniform load Q allowable down less than the 7mm state less than 1/1000
The beam maximum defluxion occurs in the L/2 place, maximum defluxion V MaxFor:
Figure 529568DEST_PATH_IMAGE003
Find the solution uniform load Q allowable according to formula (1).Can get following result by formula (1):
Figure DEST_PATH_IMAGE004
3., the whole span of beam (comprises that the weight width surpasses the beam calculated length) when receiving uniform load
The beam maximum defluxion promptly calculates uniform load Q allowable down less than the 7mm state less than 1/1000
The beam maximum defluxion occurs in the L/2 place, maximum defluxion V MaxFor:
Figure DEST_PATH_IMAGE005
Find the solution distributed load Q allowable by formula (2):
Q=43.681t
When the weight width surpasses the beam calculated length:
Q=(43.681/6582)*7100=47.12t
Q rounds and is 50t
Single door frame beam strength is checked and is calculated
Elastic modulus E=21.4 t/mm 2
Crossbeam moment of inertia I=(300*500 3-280*444 3)/12=1082671040mm 4

satisfies requirement of strength.
The door frame pillar stiffener is checked and is calculated
1. stability is checked
When door frame bore uniform load, the pillar stiffener upper and lower side had bracket to strengthen, so the termination does not only have deflection but also do not have corner, can think that pillar stiffener is an end freely-supported, and the other end is a fixed sturcture, and figure B is seen in stable school
