The invention relates to a bundling and hoisting method of a loop reactor. In a petrochemical deice, a main lifting lug and a tail sliding lifting lug are respectively arranged at the head and tail ends of equipment to be hoisted at large, and the equipment is easily subjected to great deflection and deformation. The loop reactor is provided with four hoisting points; phi39 steel wire ropes are wound and bundled at the hoisting points of the loop reactor and are wound and bundled for seven rings at each hoisting point; each hoisting point is connected with a main hoisting rope through a 50T rope buckle; each main hoisting rope adopts a phi83mm steel wire rope buckle, and two rope buckles are arranged one each loop; a first phi83mm rope buckle on each loop is connected with two 50T rope buckles; and a 150T single pulley is hung on each rope buckle and is connected through a 150T clamping ring, a second phi83mm rope buckle and a hanger. According to the hoisting method disclosed by the invention, the deflection and deformation caused by self gravity of the equipment are greatly alleviated, and the equipment does not easily deflect, so that the hoisting quality and the hoisting efficiency are ensured.
Description
Technical field
the invention belongs to chemical plant hoisting technology field, be specifically related to a kind of binding hanging method of annular-pipe reactor.
Background technology
In recent years, along with the fast development of petrochemical complex, polypropylene in chemical products, the great attention that polyethylene has also obtained chemical enterprise, and one of nucleus equipment---annular-pipe reactor in its device, although not heavy, its shape is long and thin, rigidity is little, flexible large, equipment distortion how to control hoisting process becomes difficult point and the emphasis in equipment hoisting process.
In petrochemical unit, the general normal initial and end two ends that main hoisting ear, slipping tail hanger are separately positioned on to equipment of equipment hoisting, if cover is used in the lifting of annular-pipe reactor simply in this way, so at the middle part of annular-pipe reactor, can produce larger amount of deflection and distortion because of its deadweight and end suspension centre, totally unfavorable to apparatus body like this, easily cause lifting quality accident.
For better control loop pipe reactor is in the distortion of hoisting process, can adopt main hoisting ear, slipping tail hanger all close to equipment center (center of gravity), can reduce like this amount of deflection, moment of flexure that annular-pipe reactor produces because of deadweight, thereby reduce the distortion of hoisting process; But, if main hoisting ear from center of gravity too close to, in hoisted in position process, the easy deflection of equipment, squareness are bad, are unfavorable for that equipment is in place.Therefore, select main hoisting ear, the rigidity (reducing distortion) not only will ensure equipment hoisting time, also will be conducive to equipment installation in position.
Summary of the invention
The object of this invention is to provide a kind of binding hanging method of avoiding distortion in hoisting process, preventing the annular-pipe reactor of deflection.
The technical solution adopted in the present invention is:
The binding hanging method of annular-pipe reactor, is characterized in that:
Realized by following steps:
Four suspension centres are set on annular-pipe reactor, Ф 39 wirerope-windings are bundled into the suspension centre place of annular-pipe reactor, each suspension centre place is wound around binding 7 circles, and each suspension centre selects 50T snap ring to be connected with main hoisting rope;
Main hoisting rope is selected Ф 83mm wire line hitch, respectively on every endless tube distributes 2, and first wire line hitch of every endless tube is connected with the 50T snap ring at suspension centre place, hangs 1 150T single block on this sling, single block use 150T snap ring, second wire line hitch and suspension hook connection.
Four suspension centres are set on annular-pipe reactor, and first and second suspension centre is symmetricly set on apart from the position of endless tube straight section top 0.1L, and third and fourth suspension centre is symmetricly set on apart from the position of endless tube straight section top 0.29L.
The present invention has the following advantages:
Hanging method of the present invention can greatly reduce the deflection deformation that equipment causes because of deadweight, and equipment is difficult for deflection occurs, and has guaranteed lifting quality and lifting efficiency; By adopt different binding modes to contrast discovery to hoisting point position, hanger is set and can makes lifting measure convenient, safer.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
In figure, 1-coaster is joined snap ring, 2-steel rope, 3-expansion joint, 4-jig, 5-annular-pipe reactor.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
The annular-pipe reactor of polypropylene, polyethylene device, because it is long thin, rigidity is little, flexible large, in the time of lifting, in order to reduce distortion, the one, main hoisting point should arrange many suspension centres, and four suspension centres of operated by rotary motion (hanger) are advisable, and four-point lifting be easy to equipment vertically, be easy in place; The 2nd, on main hoisting point (four hangers), two leading sheaves must be set, make every two hangers because of the transmission of leading sheave stressed evenly.
To the annular-pipe reactor of polypropylene, polyethylene device, length is in 40m, and main hoisting point can arrange apart from the about 5m of head, and slipping tail suspension centre can be arranged on apart from the about 10m of afterbody place; The hanger at main hoisting point place should be set to board-like hanger or tube shaft type lifting lug; Length is in the time that 60m is above, and main hoisting point should arrange many suspension centres, is advisable with four, and first and second main hoisting point is 0.1L apart from straight section head, and third and fourth main hoisting point is 0.29L apart from head, and slipping tail suspension centre is 0.235L apart from afterbody; The hanger at all suspension centres place should be set to board-like hanger, is not preferably tube shaft type lifting lug, prevents in hoisting process that equipment is because rotating the unhook of colliding with.To the main hoisting point of many suspension centres, stressed evenly in order to ensure each suspension centre (hanger), should adopt leading sheave, in hoisting engineering, equipment steadily rotates because of the effect of leading sheave, the stressed equal and opposite in direction that each suspension centre (hanger) is located.
The hanging method of annular-pipe reactor involved in the present invention, realized by following steps:
Four suspension centres are set on annular-pipe reactor, Ф 39 wirerope-windings are bundled into the suspension centre place of annular-pipe reactor, each suspension centre place is wound around binding 7 circles, and each suspension centre selects 50T snap ring to be connected with main hoisting rope;
Main hoisting rope is selected Ф 83mm wire line hitch, on every endless tube each 2, first Ф 83mm sling of every endless tube is connected with 2 50T snap rings at suspension centre place, hangs 1 150T single block on this sling, and 150T snap ring for single block, second Ф 83mm sling and suspension hook connect.
Four suspension centres are set on annular-pipe reactor, and first and second suspension centre is symmetricly set on apart from the position of endless tube straight section top 0.1L, and third and fourth suspension centre is symmetricly set on apart from the position of endless tube straight section top 0.29L.
