Description
Technical field
The present invention relates to the suspension rod of module hoisting, more particularly to the suspension rod of cracking oven module lamellar body lifting.
Background technology
The lifting device that trapeze is commonly used as inside plants, its structure type and hanger pattern be all largely by
Factory's autonomous Design.Trapeze can be divided into according to agent structure type：Shaped steel formula, casing beam type, plate spell formula.Hanger on trapeze
It can be divided into：Otic placode type, jack-post type.
1st, shaped steel formula
Feature：Ear is typically welded in lower flange plate surface thereon as trapeze main body using single H profile steel or I-steel
Template suspension centre.
Advantage：Trapeze manufactures that relatively easy, weight is smaller.
Shortcoming：Because H profile steel or I-steel can not bear the larger transverse load perpendicular to web direction, and it is actual
Such horizontal force can be produced, therefore such trapeze is only used for lifting by crane because hanger installation accuracy problem in lifting
Loose mail or small-sized plate etc..
2nd, casing beam type：
Feature：The body structure generally combined by welded H section steel or the welding of hot rolled H-shaped and steel plate is as trapeze
Main body, otic placode type suspension centre is welded in its upper and lower surface, or jack-post type suspension centre is welded in its side.
Advantage：It is high to lift load, flexing resistance is good, and stability is good, and intensity is larger.
Shortcoming：Trapeze welding job amount is larger, and fabrication cycle is longer, and jack-post type suspension centre makes complicated, integral manufacturing cost
It is higher.
3rd, plate spells formula：
Feature：Plate is spelled formula trapeze main body and generally formed by steel plate splicing, and such trapeze section form is various, usually becomes and cuts
Face form.
Advantage：Load is higher, and outward appearance is typically more novel.
Shortcoming：Manufacture difficulty is larger, and welding capacity is big, and fabrication cycle is relatively long.
Chemical project due to the particularity of its modules structure, work progress be for the demand of trapeze it is very big,
It is frequently necessary to carry out lifting work using several trapezes simultaneously, but it is that comparison is answered that the higher trapeze of load, which conventionally makes,
It is miscellaneous, it is necessary to expend more human and material resources, financial resources, when project duration and more nervous fund, this quasi-tradition is hung
Thick stick does not apply to simultaneously.
The content of the invention
The technical problems to be solved by the invention are to overcome top load suspension rod complex manufacturing technology in the prior art, and cost is high
The shortcomings that.
In order to solve the above-mentioned technical problem, the trapeze for being used to crack the lifting of oven module lamellar body of the invention, including suspension rod master
Body, main hanger, secondary hanger, the main hanger are arranged on the upside of suspension rod main body, and the secondary hanger is arranged on the downside of suspension rod main body, institute
It is pipe to state suspension rod main body.Compared with conventional tank beam type trapeze, pipe possesses suitable structural strength, but making is more easy,
Welding job amount is small；Meanwhile add the ability that trapeze bears transverse load.
In above-mentioned technical proposal, the suspension rod main body is provided at both ends with shrouding.Deep bracket as hanger so that hang
Ear can bear horizontal active force；As the shrouding of pipe, prevent foreign matter from entering pipe, prevent pipe internal corrosion, increase simultaneously
The radial strength of pipe.
In above-mentioned technical proposal, the main hanger and secondary hanger form by mainboard, compound plate and bracket, the mainboard welding
On suspension rod main body axial direction, the mainboard is provided with through hole, and the compound plate is arranged on through hole both sides, and the bracket is arranged on mainboard
Both ends, the bracket and mainboard are vertically arranged.More traditional shackle plate adds two pieces of compound plates, respectively positioned at mainboard both sides, increases
Hanger shear resistance is added.
In above-mentioned technical proposal, the bracket is wing structure, and downside and the suspension rod main body section of bracket match, described
Side roof part is provided with recess under bracket.Both sides add bracket, increase the fusion length of hanger and pipe, increase load energy
Power, while add hanger and bear active force perpendicular to page.
In above-mentioned technical proposal, the main hanger is 2, is separately positioned at the length of suspension rod body end 1/5, institute
Secondary hanger is stated as 5, is respectively provided with one in suspension rod body end and centre, remaining two are separately positioned on distance centre 1/5 and grow
At degree.Hanger position calculates by SACS models, is optimal forced position, compared to more traditional trapeze, moves hanger position,
Add the integral hoisting performance of trapeze.
In above-mentioned technical proposal, the mainboard positioned at the secondary hanger of boom end is welded on suspension rod main body and shrouding.
In above-mentioned technical proposal, the shrouding top is semi-circular structure, and bottom is rectangular configuration.As the pedestal of trapeze,
The structure can be easy to trapeze to lie against ground, not topple over, and reduce the damage of paint, be advantageous to the long-term storage of trapeze.
In above-mentioned technical proposal, the suspension rod main body, main hanger, secondary hanger and shrouding use more than Q235B materials.
In above-mentioned technical proposal, the pipe isSpecification.
Due to, as trapeze main body, either directly buying seamless steel pipe, or the plate with respective thickness using pipe
Carry out bent plate and make relatively simple convenience, cost is relatively low；Two end-plates can prevent foreign matter from entering pipe, prevent from becoming rusty in pipe
Erosion, while increase the radial strength of pipe, trapeze can be also easy to lie against ground, do not toppled over, subtracted as the pedestal of trapeze
The damage painted less, be advantageous to the long-term storage of trapeze；Hanger adds the overlapping form of compound plate using mainboard, can significantly increase
The load-carrying ability of hanger, and the requirement for hanger thickness of slab can be effectively reduced, effectively reduce cost of manufacture, such steel
Plate purchase is also more convenient；Hanger and the fusion length of trapeze main body welding can be significantly increased in bracket, increase the load of trapeze
Ability, and the contact area of hanger and pipe can be increased, the surface stress of trapeze cylinder is reduced, further improves trapeze
Safety coefficient.
The more existing trapeze of trapeze of the present invention is compared under the performance of equal load, can greatly reduce cost of manufacture,
Reduce manufacture craft.When being particularly suitable for project duration and more nervous fund, with less cost produce load compared with
High trapeze, and the actual lifting demand of project can be met.
