Description
Technical field
The invention belongs to machinery field, construction site, be specifically related to a kind of construction site small-scale terrestrial hanging device
And method of work.
Background technology
Architectural Equipment is a kind of critically important machinery that in construction, each engineering project can use, and mostly builds
The equipment of building has the advantages that monomer weight is relatively big, device structure is more complicated.It is wide that construction site relates to safety factors aspect, so,
How to carry out the hoisting and hanging design of Architectural Equipment, it is ensured that construction safety, is a very important job.Then, to lifting
The requirement of method is further strict, concrete hanging method require to have following some:
Guaranteeing technical feasibility: because job site scene is chaotic, personnel are more, construction trade categories diversity is big, prefabrication quantity,
Quality, length are not of uniform size, therefore when structure hoisting construction is carried out, therefore, to assure that technical feasibility.And lift each time
Environment is different from, and the natural conditions such as wind and rain thunder and lightning and sun degree of shining have a strong impact on lifting work and carry out.Therefore for each
Plant prefabrication and be required for timely match technology means, it is to avoid technical limitation, it is ensured that technical feasibility wins, promote structure hoisting work
Make the safest carrying out.
Add strong security: engineering safety is the problem must paid attention in construction, because the personal safety of workmen is remote
More important than the economic benefit that construction brings.So structure hoisting construction must strengthen security knowledge, prevent unexpected injury
Occur.Select practicable techniques to carry out safety analysis for job site concrete condition, find out unsafe factor, professional people in time
Member should carry out emphatically job site commander, gives enough technological guidances, pinpoints the problems in time and solve a problem promptly, in a word, really
Protect lifting construction site safety orderly.
Duration progress analysis: duration progress analysis to be paid attention in structure hoisting construction, does not occur in order to degree of leading up forward is overworked
Phase and cause lifting error or the phenomenon of Hoisting Security accident.Detail design personnel should set duration progress in advance, carries out and hangs
Dress duration progress analysis work, explicitly pointing out the different duration should use different hoisting technology, uses different hanging method to execute
Work, makes a concrete analysis of in conjunction with concrete actual clear condition, it is ensured that lifting construction reasonable benefit/risk operation, meets relevant building requirements, from
And do not affect whole building engineering construction progress.
Existing lifting common method has following several:
Mechanization hanging method: machinery when using the lifting equipment liftings such as crawler crane, autocrane, derrick crane
Automaticity is high, it can vertical lift, move horizontally.The work arbitrarily moved at space requirement is all the strength by machinery
Completing, the most least a portion of work operates the most by hand as extension unloads the operations such as rope.Some hoisting machineries such as autocrane
The movement of itself is also that the machinery by its own is carried out, it is not necessary to this hanging method hand-manipulated i.e. mechanization hanging method.
This method is easy to operate, speed fast, high safety, can alleviate the labor intensity of operating personnel.But its range is sometimes
It is subject to certain restrictions, as the highest to the requirement of road in Mobile hoisting machinery.
Semimechanized hanging method: using tackle pulley, hoist engine, gin pole to lift, its mechanization degree is just
Greatly lower, and any mobile of three directions can not be completed simultaneously in space, typically can accomplish arbitrarily to move in a vertical
The dynamic vertical that maybe can only do moves this hanging method and needs to consume more labour in the preparation, transport installation and removal of instrument.
Mechanization and semi-mechanization lifting force method are used in combination: under general occasion, the elevating capacity due to lifting machine is inadequate,
Utilize some semimechanized lifting work to help machinery to complete to lift work.
Under prior art conditions, the increase of construction site hanging device construction cost and operating cost will become inevitable,
The shortcomings such as existing traditional handicraft, that processing method has technological process is long, controls complexity, lifts inefficiency, and processing cost is high.
