Abstract
The utility model provides a ring beam that is used for cable wire hydraulic lifting chimney steel inner tube promotes roof beam connect first and last by four to constitute one and steel inner tube outer wall matched with circular ring shaped structure, promote the roof beam and be by inner circle web, outer lane web, go up the pterygoid lamina and down the cross -section formed of pterygoid lamina be box structure, lie in and offer the line hole that is used for wearing to establish steel strand wires on the last pterygoid lamina, time pterygoid lamina of intermediate position. So the utility model discloses a power from the transmission of steel inner tube to the cable wire has been solved to the ring beam, makes force -bearing point clear and definite, and it is clear to pass the power route to respectively promoting equipment or dismantlement convenience between the roof beam in the ring beam, can having enough to meet the need the use many times, it is good to synthesize economic benefits.
Description
Technical field
The utility model relates to chimney technical field, is specifically related to a kind of ring beam for cable wire hydraulic pressure lift inner steel cylinder of chimney.
Background technology
Industrial chimney mostly is up-thin-low-thick cylinder, is generally used in the large factory building of industry, as cauldron, smeltery, power plant etc.The construction of its chimney directly affects civil engineering total lever factor and the key factor such as safety, quality of its industry.Early stage industrial chimney mainly adopts steel concrete stack shell, brick liner is main design, but from permanence operation, finds the problems such as ubiquity stack shell distress in concrete and inside lining building quality is bad, has influence on the application life of chimney.Industrial chimney design and construction afterwards begin one's study apply with steel concrete urceolus wind resistance antidetonation, inner core for steel cylinder carry out discharging fume, corrosion resistant sleeve-type chimney.The corrosion protection design of current large-size thermal power plant inner steel cylinder of chimney trends towards adopting titanium steel composite board, and titanium steel composite board is expensive, is reduce construction costs, the form of structure of steel inner cylinder from isometrical, self-supporting to reducing, hang future development.The method of cable wire hydraulic lifting installation inner steel cylinder of chimney compares the method for pneumatic jack or hydraulic lifting, and adapt to the steel inner cylinder of form of ownership, therefore the method for cable wire hydraulic lifting installation inner steel cylinder of chimney is more and more applied.
Cable hydraulic lifting device take hydraulic oil as power, promotion hydraulic cylinder piston moves back and forth, make to carry out load conversion between the upper clamping body that connects with piston upper end and the lower clamping body be connected with inferior part of the cylinder block, and utilize flexible cable (steel strand) to draw load-bearing, thus realize the lifting appliance promoting (or decline) weight.Because steel inner cylinder is reducing, it is improper that steel strand Hoisting Position is selected, then easily shake and bring potential safety hazard.
utility model content:
The purpose of this utility model is just to provide a kind of ring beam for cable wire hydraulic pressure lift inner steel cylinder of chimney, solves power from steel inner cylinder to the transmission of cable wire.
The utility model technical problem is solved by following technical proposal:
For a ring beam for cable wire hydraulic pressure lift inner steel cylinder of chimney, being joined end to end to connect by four lifting beams forms a circular ring matched with steel inner cylinder outer wall; The cross section that described lifting beam is made up of inner ring web, outer ring web, upper flange and lower wing plate is box structure, is positioned at the string holes upper flange in centre position, lower wing plate offered for wearing steel strand.
Further, be bolted between described lifting beam.
Further, the both sides being positioned at string holes are equipped with the radial support plate connecting inner ring web and outer ring web, are connected between two radial support plates by cross binding plate.
Joined end to end by four lifting beams and connect makeup ring beam casing on inner steel cylinder of chimney outer wall, steel inner cylinder outer wall is first welded with a ring channel-section steel, the upper surface of ring beam contacts with the soffit of annular groove steel, holds by ring beam the transmission that channel-section steel circle carrys out realizable force.Then by steel strand through the string holes on ring beam, and steel strand are fixed in lifting beam by lower anchor head, promote finally by hydraulic cylinder or the ring beam that declines to realize lifting or the decline of steel inner cylinder.
According to Finite element analysis results, in steel inner cylinder lifting process, the lifting beam stress near string holes place is large, and the lifting beam stress away from string holes place is little.So the cross section of lifting beam is gradual change shape box structure, the sectional area namely near string holes place is comparatively large, and increases cross binding plate and radial support plate at string holes place, to improve the strength and stiffness of local pressure point.
So ring beam of the present utility model solves power from steel inner cylinder to the transmission of cable wire, make force part clear and definite, Path of Force Transfer is clear, and assembles or convenient disassembly between each lifting beam in ring beam, and repeatedly can have enough to meet the need use, overall economic efficiency is good.

Detailed description of the invention
As Figure 1-3, a kind of ring beam 2 for cable wire hydraulic pressure lift inner steel cylinder of chimney, is joined end to end by four lifting beams 1 and connects and be fixed connection by bolt and form a circular ring matched with steel inner cylinder outer wall; The cross section that described lifting beam 1 is made up of inner ring web 11, outer ring web 12, upper flange 16 and lower wing plate 17 is box structure (as shown in Figure 2), is positioned at the string holes 15 upper flange 16 in centre position, lower wing plate 17 offered for wearing steel strand.
Further, the both sides being positioned at string holes 15 are equipped with to connect between inner ring web 11 and radial support plate 13, the two radial support plate 13 of outer ring web 12 and connect 14 by cross binding plate.
During use, as shown in Figure 4, four lifting beams 1 are connected into ring beam 2 by bolt head and the tail and is socketed on steel inner cylinder 4 outer wall, upper surface contacts with annular groove steel 3 soffit be welded on steel inner cylinder outer wall.Four bundle steel strand 5 of four hydraulic jack to be each passed through on ring beam the string holes 15 in corresponding lifting beam, and the soffit that the bottom of steel strand 5 is anchored at ring beam 2 by lower anchor head 7, the steel strand 5 being positioned at steel inner cylinder 4 upper port are connected to steel inner cylinder 4 upper port by only shaking device 6.Hydraulic jack realizes lifting or the decline of steel inner cylinder 4 by traction steel strand 5, the device 7 that only shakes prevents higher than can effectively play during ring beam the only rolling effect that a trim by stem is oblique or swing in steel inner cylinder center of gravity.
Above embodiment is not limited only to protection domain of the present utility model, all modify based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
