Abstract
Assembly fixture is lifted by crane in major diameter tube bank and application method relate to heat exchanger tube assembly field, and it is inconvenient to have overcome the prior art operation, hoists the difficulty that has a big risk. Its structure has: subassembly 3 is drawn in tube bank hanger plate subassembly 1, fixed pulley group spare 2, tube bank, tube bank hanger plate subassembly 1 comprises arc board 4 and lug 5, fixed pulley group spare 2 fix on the basic platform. During the use: drawn subassembly 3 to install the intermediate position at the tube bank front end tube bank, wire rope walks around fixed pulley group spare 2, and the tube bank is passed to its one end, is drawn subassembly 3 to link to each other with the tube bank, and the wire rope other end is connected with another crane, wire rope passes through fixed pulley group spare 2, and pulling tube bank horizontal direction at the uniform velocity gets into the casing. The major diameter tube bank is when equipment hoist and mount business turn over casing, and speed is evenly controllable, and operational risk is little, the commonality is strong, and applicable tube bank in various different diameters is assembled, improve the tube bank packaging efficiency by a wide margin, reduced tube bank assembly costs.
Description
Technical field
Apparatus of the present invention relate to heat exchanger tube lifting and assembling field.
Background technology
Heat exchanger is to apply one of unit the most widely in the industries such as chemical industry, oil, pharmacy and the energy.China's dynamics of investment in the construction of the projects such as large-scale oil refining, large-scale Coal Chemical Industry, big ethylene strengthens in recent years, and scale is the most increasing.Adapting with the complexes maximized, heat exchanger is also keeping the large-scale development, and manufacture and the installation of this heat exchanger are had higher requirement.Large heat exchanger tube bank assemble in owing to device diameters is excessive, tube bank quality is overweight, there is the problems such as operating difficulties, danger are bigger.At present when assembling tube bank, generally needing to install tube bank slideway in heat exchanger shell, this certainly will add equipment investment cost.When assembling tube bank, relying on manpower to draw by jack, installation difficulty is big, restrain that hauling speed is uneven is easily caused tube bundle deformation；Installation effectiveness is low, is unsuitable for producing in enormous quantities.
Summary of the invention
We problem to be solved are: overcome large diameter pipe in prior art to do up and hang and operation inconvenience in assembling process, the difficulty that lifting risk is bigger.
The invention provides large diameter pipe to do up and hang assembly tooling, its structure has: tube bank boatswain chair assembly 1, fixed block assembly 2, tube bank tension assembly 3；Wherein said tube bank boatswain chair assembly 1 is made up of two symmetrical hangers 5 at arc plate 4 and arc plate two ends；Described fixed block assembly 2 is made up of the fixed pulley being fixed on basic platform；Described tube bank tension assembly 3 is made up of the steel pipe that intensity is good, can be with tube bank transverse plane laminating.
Large diameter pipe does up and hangs the using method of assembly tooling and be:
1. put and restrain on the arc plate 4 of tube bank boatswain chair assembly 1, crane is sling tube bank to certain altitude position by the steel wire rope that is fixed on tube bank boatswain chair assembly 1 symmetrical hanger 5 above, move in parallel again and tube bank about 1/3 length is sent in housing, make tube bank slideway implement on housing；
2. Fixed Tube-sheet Reboiler, changes the lifting position of tube bank boatswain chair assembly 1, and in advance gasket seal assembling is put in place；
3. tube bank tension assembly 3 is arranged on the centre position of tube bank front end；Fixed block assembly 2 walked around by steel wire rope, and its one end, through tube bank, is connected with tube bank tension assembly 3, and the steel wire rope other end is connected with another crane；
4. another crane the most at the uniform velocity tense wire rope, fixed block 2 tension tube bank tension assembly 3 walked around by steel wire rope；Vertical direction crane interoperation simultaneously, makes tube bank keep certain height by tube bank boatswain chair assembly 1；Tube bank at the uniform velocity enters housing by the tension level direction of steel wire rope, carries out tube bank and assembles.
The invention has the beneficial effects as follows: major diameter tube bank is when assembling lifting turnover housing, and speed uniform, controllable, operational risk is little；Highly versatile, the tube bank being applicable to various different-diameter assembles；Tube bank packaging efficiency is greatly improved, reduces tube bank assembly cost；Easy and simple to handle, safe and reliable, reduce the operation level requirement that tube bank is assembled workmen.Solve the difficult point during large heat exchanger tube bank lifting and assembling.

Detailed description of the invention
As it can be seen, present configuration includes restraining boatswain chair assembly 1, fixed block assembly 2, tube bank tension assembly 3；Wherein said tube bank boatswain chair assembly 1 is made up of two symmetrical hangers 5 at arc plate 4 and arc plate two ends；Described fixed block assembly 2 is made up of the fixed pulley being fixed on basic platform；Described tube bank tension assembly 3 is made up of the steel pipe that intensity is good, can be with tube bank transverse plane laminating.
Using method:
The arc plate 4 restraining boatswain chair assembly 1 during lifting pads below tube bank, and the gravity of tube bank is evenly distributed on arc plate 4, can be to having restrained cushioning and protection, it is ensured that tube bank lifting steadily, can prevent tube bundle deformation；
Crane is sling tube bank to certain altitude position by the steel wire rope that is fixed on tube bank boatswain chair assembly 1 symmetrical hanger 5 above, then moves in parallel tube bank about 1/3 length is sent in housing, makes tube bank slideway implement and plays a supporting role on housing；
Then Fixed Tube-sheet Reboiler, changes the lifting position of tube bank boatswain chair assembly 1, and in advance gasket seal assembling is put in place；
Tube bank tension assembly 3 is arranged on the centre position of tube bank front end；Fixed block assembly 2 walked around by steel wire rope, and its one end, through tube bank, is connected with tube bank tension assembly 3, and pulling force acts on the two ends of tension assembly 3 steel pipe, it is ensured that tube bank is by uniform horizontal direction pulling force；The steel wire rope other end is connected with another crane, and steel wire rope is converted into the pulling force of horizontal direction by the pulling force of 2 vertical direction of fixed block；
Vertical direction crane interoperation simultaneously during operation, makes tube bank keep certain height by tube bank boatswain chair assembly 1；The tension level direction that tube bank in housing utilizes slideway to pass through another crane rope at the uniform velocity enters housing；Carry out tube bank to assemble.
Note preventing steel wire rope from directly contacting with tube bank, rub, scratch is restrained.
It is steady that the present invention ensures that housing is drawn in tube bank, and speed is controlled.
