Abstract
The utility model discloses an extensible special lifting platform for the corrosion protection reconstruction of a chimney, which is used for the internal corrosion protection reconstruction of the chimney. The platform comprises a hub cylinder, radial spars and inclined stay cables, and adopts a bolt-connection assembly structure. The diameter of the chimney is gradually reduced, and the radial spars are sleeved by adopting square steel pipes of three specifications, so that the diameter of the platform can be changed as per the position variation of the construction procedures; the center of the platform adopts a hub cylinder structure, and the inclined stay cables are used for bearing the construction load of the platform; besides, the platform can be operated at all the positions inside the chimney in virtue of the winding engine adopted as a lifting mechanism by the platform.
Description
Technical field
Expandable type chimney anticorrosion transformation Special-purpose lifting platform is mainly used in the field of the conventional concrete chimney transformation in steam power station at present, also can participate in the field of all kinds of towering structure constructions.
Background technology
The domestic operation platform used in chimney construction generally adopts the operation platform of H formed steel construction at present, the type operation platform is processed according to the diameter of chimney, do not possess flexible condition, and can't reuse, platform structure is from great, security performance is lower, and the embedded part on the suspended structure general using chimney concrete structure of top is installed, the rebuilding construction of the not too suitable conventional concrete chimney of the type platform.The chimney anticorrosion of taking charge of development, invention by me is transformed special-purpose operation platform and just is being based on the problems referred to above and is tackled key problems, and can meet following characteristics:
1, platform diameter can be expanded, and meets the construction of differing heights different-diameter, and the extended mode advantages of simple;
2, the design of this platform should meet the requirement of certain working load, meets the requirement that steel work is installed on this platform;
3, the suspended structure at top is installed simply, and stability meets the demands;
4, the propulsion plants design of this platform is reasonable, practical safety;
5, a transportation cage is set, meets the upper and lower requirement of personnel;
6, overall structure deadweight is lighter, less to the load of the loading of original structure.
Summary of the invention
In order to overcome original chimney construction platform bearer ability, defect that can not free-extension, the utility model provides a kind of expandable type chimney anticorrosion transformation Special-purpose lifting platform, and this platform can not only meet the construction of arbitrary height, arbitrary diameter, has also possessed stronger supporting capacity.
The utility model solves the technical scheme that its technical problem adopts: expandable type chimney anticorrosion transformation Special-purpose lifting platform is comprised of Decorative drum, radiation beam and suspension cable three parts, load platform born by suspension cable is delivered on Decorative drum, greatly improved the supporting capacity of platform, during the operation platform Platform Structure Design, by the working load standard value of GB50113-2005 " sliding shuttering engineering legislation " predetermined operation platform, take, simultaneously the weight of bearing carrier, constructor's weight, many loads such as weight of construction equipment.
In order to reach the construction of arbitrary diameter position in chimney, the radiation beam has adopted the square tube of three kinds of different-diameters to be socketed, and has played the effect of free-extension, and square tube can be to external extension, and it is 50cm that single is regulated length, and square tube is connected with square tube pin formula; Purlin adopts fabricated structure, can be combined according to different length, and suspension cable adopts the pin formula to be connected with square tube, can be installed on each position, and easy accessibility connects reliable.
The top hitch of this platform adopts trussed construction, two secondary main couples and fourth officer jack truss, consists of.Compare deadweight with original hitch and greatly alleviate, supporting capacity but improves greatly.Trussmember is all with bolts, is convenient to transportation and installs.
The beneficial effects of the utility model are, increase the supporting capacity of platform by the application of this platform, improved the safety in utilization of platform, greatly improved the efficiency of construction of work high above the ground, and applied range, by adjusting platform diameter, be applicable to the chimney of various height, size, reusable, economic benefit is preferably arranged.

The specific embodiment
Expandable type chimney anticorrosion transformation Special-purpose lifting platform is comprised of with suspension cable (3) three parts Decorative drum (1), radiation beam (2), and load platform born by suspension cable is delivered on Decorative drum, and bolt for steel structure is formed by connecting.The radiation beam is with 160 * 160 * 5,, 140 * 140 * 5,120 * 120 * 5 three kinds of size square steel pipes are socketed, to reach retractable purpose, each amplitude of adjusting is 50cm, every adjustment once, is fixed square tube with latch, and the radius of variation is 4.5m to 17.5m.Decorative drum is by [20a steel ring (4) three roads, vertical rod L100 * 6 angle steel (5) and brace φ 63*4 pipe form.What the purlin of operation platform (7) adopted is the 10# channel-section steel, adopts combined type, can be adjusted according to spacing.The length of suspension cable can be adjusted by flower basket bolt (8), the every expansion of this platform once, the position of suspension cable also need corresponding to external-adjuster once.Top truss is comprised of main couple (9) and jack truss (10), main couple top-bottom chord (11) is H250 * 250 * 9 * 14, web member (12) is Two bors d's oeuveres L100 * 6 angle steel and Two bors d's oeuveres L75 * 6 angle steel, the jack truss main chord is the I20A i iron, and web member is Two bors d's oeuveres L75 * 6 angle steel and L75 * 6 angle steel.The actuating unit of this platform is comprised of 2 10 tons of hoist engines and 15 tons of twin-roll hoist engine, and platform is moved up and down by wire rope.
When this operation platform is used, top hitch (13) first is installed, operation platform basic structure (14) is promoted to aerial assigned address by steel wire rope of windlass (15) after has assembled on ground.As operation platform size after the chimney change in radius needs to adjust, operation platform is down to the 0m layer and is expanded, rising to the use height.For cooperation, personnel are easy for going up and down, and this platform is the transportation cage of configure dedicated also, and personnel arrive the operation platform position by this cage.
