Description
Technical field
The utility model relates to the checking maintenance instrument of petrochemical unit, the lifting special tool that uses when being a kind of the maintenance.
Background technology
In some oil refinery factories, because factors such as general layouts, framed structure setting, technological process trend, cause the other crane of some heat exchanger can't erect-position; No suspension centre above raising the nose above water to breathe; Or the reasons such as technology, instrument pipeline of gathering below the suspension centre cause heat exchanger floating head dismounting difficulty, and then influence heat exchanger and take out a series of activities such as cored, tube bank, housing cleaning.Below be to be that example is enumerated in the refining and petrochemical processing units ubiquitous problem in the heat exchanger floating head disassembly process with 1,800,000 tons of/year ARGG devices:
1, the basic framework of 24 cat head oil gas-hot water heat exchangers of four layers of platform place of perforated plat column northeast side item (E10201/1-24) is not provided with hanging beam, simultaneously since the heat exchanger floating head side with install between the internal channel between across pump house, crane can't erect-position, raises the nose above water to breathe the lifting difficulty and cause.The maintenance of this heat exchanger is to adopt interim hanging beam is installed on the basis of former framework, owing to need get angry, take and tear scaffold open, utilize means materials etc. to increase the extensive work amount.
2, the three layers of deck roof oil gas in fractionation Tata southern side aftercooler, item E10204/1-8, owing to raise the nose above water to breathe the no suspension centre in top, crane reason such as can't enter the fire passage in and cause that to raise the nose above water to breathe lifting difficult, and maintenance in the past is to utilize oil-gas pipeline above the heat exchanger as suspension centre.The method damages pipeline, and use at present has been under an embargo.
3, four heat exchangers of E10204/9-11, because no hanging beam, the crane eave tile can't enter in the framework, causes the lifting difficulty, what maintenance was adopted is the hole for hoist that the grid of upper platform directly over the heat exchanger floating head is cut out a 100*100, and the pipeline that sets up a DN150 lifts as the lifting beam.But the method exists two defectives (1) to get angry, if heat exchanger valve is not tight or interior media can't be swept only, then can not adopt the method; (2) suspension centre and grid intensity are without check, and only lifting by rule of thumb causes the accident easily.
4, four heat exchanger tops of E10212/A-D are Gulf spray naphtha jar and five process pipeline, and the crane eave tile can't reach the lifting position.Maintenance is a method of adopt making door type mast-up, though also finished operation, gallows frame exist welding capacity big, need to cooperate with crane make, preserve, transportation inconvenience, commonality is poor, cost is too high shortcoming, be unfavorable for the device handling labor.
The utility model content
The purpose of this utility model is: a kind of switching heat-exchanger floating head simple and easy hoisting facility are provided, finish the heat exchanger component lifting, and require heat exchanger floating head simple and easy hoisting facility can dismantle, assemble, each parts all can be carried with manpower.
The technical solution adopted in the utility model is: heat exchanger floating head simple and easy hoisting facility, mainly by adapter plate, following locking cap, column, pallet, sleeve, last locking cap, fixing ear, digonal link, tie bolt and crossbeam are formed, column is a steel cylindrical tube. it is characterized in that: in the lower end of column is inserted in following locking cap, following locking cap is a steel pipe, end at steel pipe is welded with the end. and the bottom at following locking cap is welded with the vertical fixing plate, straight two holes of lacking are arranged on the adapter plate. the flange of adapter plate and equipment is close together, can be fixed together with the flange of screw adapter plate and equipment. be welded with an annular pallet on the column. on column, be with a sleeve, sleeve can rotate. the end welding of sleeve and crossbeam. and what crossbeam adopted is I-beam section. erecting equipment, as jack, hoist ceiling crane and pulley etc. can be suspended on the I-beam section, and to slide mobile along I-beam section. the top at the other end of crossbeam is welded with fixedly ear, fixedly the structure of ear is porose on the steel plate. be with locking cap at the top of column, be welded with fixedly ear on the outer wall of last locking cap. last locking cap fixedly the bolted connection that fixedly adopts between the ear of ear and crossbeam digonal link is arranged. will descend locking cap to be fixed on the flange of equipment, in locking cap under the column insertion, sleeve is inserted in from the column top, locking cap on the band of column top. digonal link is fixed between two hangers with bolt, finished the assembling of heat exchanger floating head simple and easy hoisting facility. at last hoist ceiling crane is suspended on the crossbeam, just can begins to lift docking facility.
When slinging weight in order to make, the column stress balance is welded with the balance hook on last locking cap.Utilize fixedly suspension cable of balance hook.
For hoist ceiling crane is walked on crossbeam, can not walk out crossbeam, on the top of crossbeam upright opening is arranged, in upright opening, be inserted with backing pin.Backing pin adopts cylindrical reinforcing bar to curve square.
The beneficial effects of the utility model: the utility model heat exchanger floating head simple and easy hoisting facility, can finish heat exchanger component lifting, and require the heat exchanger floating head simple and easy hoisting facility can dismounting, but each parts with all lifts to move of manpower, simple structure, cheap.In certain covering device maintenance process, use, solved the difficult problem that multiple different model heat exchanger size such as E10201, E10204/9-11, E10212/A-D is raised the nose above water to breathe dismounting, save about 20,000 yuan of the expense of making interim suspension bracket, saved about 70,000 yuan of crane One-Shift Costs.Use this hoisting machine tool and not only can solve the part heat exchanger and do not have suspension centre or the unknown of suspension centre intensity, also can save the crane One-Shift Costs in a large number, especially be fit to the heat exchanger checking maintenance operation of refining and petrochemical processing units.
