The main beams are regularly triangular space truss beams and the two main beams are horizontally arranged in parallel from front to back in a spaced manner; each main beam is fixedly provided with a low bearing beam at one side facing towards the other main beam; the low car is mounted on the two low bearing beams through rollers at the bottom; and the high car is mounted on upper chord rods of the two main beams through rollers at the bottom. The crane, provided by the invention, is suitable for ship manufacturing operations.
Description
Technical field
The present invention relates to mechanical equipment technology, particularly relate to a kind of technology making gantry crane on board.
Background technology
Body section aloft can have been spun 180 degree and stood up duty requirements by one of function making gantry crane on board exactly.This is that high dolly by being arranged in girder top and the low dolly being arranged in girder bottom hang and carry a body section and carry out non-interfering carriage walking and run.As shown in Figure 5, the girder 202 making gantry crane on board now with this function all adopts board-like box-structure, the bottom of two girders 202 has the outstanding girder protrusion 205 of subtend, high dolly 203 is arranged on the top of two box type girders 202, and low dolly 204 is arranged on girder protrusion 205.This existing defect making gantry crane on board is: box type girder from great, material cost is high, and this too increases the load requirement to supported on both sides leg simultaneously, causes the material cost of supported on both sides leg also to rise thereupon.
Summary of the invention
For the defect existed in above-mentioned prior art, technical matters to be solved by this invention is to provide a kind of lightweight, and what cost was low makes gantry crane on board.
In order to solve the problems of the technologies described above, one provided by the present invention makes gantry crane on board, comprises door type frame, high dolly, low dolly; Described door type frame comprises two supporting legs landed, and is fixed on two girders on two supporting leg tops; Described high dolly, low dolly are respectively equipped with suspender, and roller is all equipped with in the bottom of high dolly and low dolly;
It is characterized in that: described girder is the equilateral triangle space truss beam that top boom and lower boom are parallel to each other, two girder horizontally parallel interval layings from front to back;
Every root girder is all being fixed with a low level support rail beam towards the side of another girder, described low level support rail beam is the straight beam being parallel to girder top boom, described low dolly is arranged on two low level support rail beams by the roller of bottom, and the top of low dolly is lower than the top boom of girder, suspender on low dolly passes between two low level support rail beams, and extends to below girder;
Described high dolly is arranged on by the roller of bottom on the top boom of two girders, and the suspender on high dolly has two covers, and a set of suspender is wherein positioned at the front side of two girders, and another set of suspender is positioned at the rear side of two girders.
Further, if the span of girder is S, main depth of beam is h, and the width of girder is b, then the value of h is
the value of b is greater than
Provided by the inventionly make gantry crane on board, adopt equilateral triangle space truss beam as girder, under identical load requirement, its weight far below the existing transfer crane adopting box type girder structure, will have lightweight and that cost is low feature.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and embodiments of the invention are described in further detail; but the present embodiment is not limited to the present invention; every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in, the pause mark in the present invention all represent and relation.
As Figure 1-3, the one that the embodiment of the present invention provides makes gantry crane on board, comprises door type frame, high dolly 3, low dolly 4; Described door type frame comprises two supporting legs landed 1, and is fixed on two girders 2 on two supporting leg 1 tops; Described high dolly 3, low dolly 4 are respectively equipped with suspender, and roller is all equipped with in the bottom of high dolly 3 and low dolly 4;
It is characterized in that: described girder 2 is equilateral triangle space truss beams that top boom and lower boom are parallel to each other, two girder 2 horizontally parallel interval layings from front to back;
Every root girder 2 is all being fixed with a low level support rail beam 23 towards the side of another girder, described low level support rail beam 34 is the straight beams being parallel to girder top boom 21, described low dolly 4 is arranged on two low level support rail beams 23 by the roller of bottom, and the top of low dolly 4 is lower than the top boom 21 of girder, suspender 41 on low dolly 4 passes between two low level support rail beams 23, and extends to below girder;
Described high dolly 3 is arranged on the top boom 21 of two girders by the roller of bottom, and the suspender 31 on high dolly 3 has two covers, and a set of suspender 31 is wherein positioned at the front side of two girders, and another set of suspender 31 is positioned at the rear side of two girders.
When the embodiment of the present invention uses, utilize the suspender suspended body section on high dolly and low dolly, high dolly is two cantilever single supported beam systems, two cover suspenders on high dolly are placed in two cantilever end, the function run that hoists up and down is realized by the outside of two girder, suspender on low dolly is realized the function hoisted up and down by two girder inner space, the vertex of low dolly is lower than the top boom of girder, can ensure that high dolly and low dolly do not interfere with each other in operation, low dolly can be passed from the below of high dolly, thus the body section of hanging can be stood up 180 degree aloft, so that construction.
As shown in Figure 4, in the embodiment of the present invention, if the span of girder is S, main depth of beam is h, and the width of girder is b, then the value of h is
the value of b is greater than
The value of h exists
time, can ensure that the vertical shake frequency of main beam structure meets the comfort requirement of human body, the value of b is greater than
then can ensure that the horizontal vibration frequency of main beam structure meets the comfort requirement of human body;
Such as:
During S=70000mm,
Get h=4900mm, then have
Get b=2000mm;
If: Q1 is high dolly lift heavy, and q1 is the deadweight of high dolly, and P1 is high dolly mid-span deflection (lifting operating mode), and Q2 is low dolly lift heavy, and q2 is the deadweight of low dolly, and P2 is low dolly mid-span deflection;
When Q1=100 × 10
4n, q1=32 × 10
4n, Q2=50 × 10
4n, q2=16 × 10
4n, then:
P2＝Q2+q2＝6.6×10
5N
When design load is identical, the girder of the embodiment of the present invention from the important box type girder being far lighter than traditional transfer crane, and because the girder of the embodiment of the present invention is made up of many rod members, manufacturing process is relatively simple, and there is less windage usefulness, be particularly suitable for using in the large-scale navigating equipment factory of coastal manufacture.
