Description
Technical field
The present invention relates to a kind of electric product hanging method and device, refer in particular to a kind of hoisting method and device of box type transformer, be mainly used in lifting by crane transformer in the transportation handling process of box type transformer.
Background technology
box type transformer (claiming again box-type substation) is a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment, indoor by certain connection plan row all-in-one-piece prefabrication, outdoor close-coupled controller switching equipment, be about to high powered, transformer pressure-reducing, the functions such as low-voltage distribution are organically combined, be arranged on a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in the steel construction casing, electromechanical integration, the power transmission and transforming equipment of totally-enclosed operation, this power transmission and transforming equipment concentrates design in box-type shell traditional transformer, has volume little, lightweight, low noise, low-loss, high reliability, be widely used in residential quarters, commercial center, light station, the airport, factories and miness, enterprise, hospital, the places such as school.Box type transformer is since coming out, and the modularization degree is high, batch production is prefabricated owing to having, easy for installation, handsome in appearance, and degradation advantage under holistic cost so development is very rapid, has accounted for 70% of distribution transformer at countries in Europe, and the U.S. has accounted for 90%.The develop rapidly that China builds along with urban modernization, the continuous renewal transformation of urban power distribution network is also to be widely used.
But because box type transformer is that all power transmission and transforming equipments have been concentrated in a casing, though the more original whole system of volume is much smaller, but numerous device combinations has been arranged after all together, therefore complete equipment still seems very heavy, generally all need to carry and install by lifting, especially very careful in hoisting process, otherwise be easy to because the Heave Here is bad, or the steel wire rope installation is bad, is easy to cause the damage of casing; The lifting of present box type transformer is all generally to be provided with 4 for the suspension hook of lifting on the framework of bottom half, when the hanging box type transformer, steel wire rope directly is enclosed within fixedly on suspension hook, lift by crane, this hoisting method, though simple and convenient, find that in actual applications this fixing suspension hook is easy to because the friction of steel wire rope on the fixing sharp-pointed arm of angle of suspension hook causes the steel wire rope damage; General suspension hook is with the thick steel plate of 20mm, becomes blank with " copying cutting machine " blanking, then economy-combat grinding and polishing Seterolithography; Be welded at last assigned address.There are following some shortcomings in the suspension hook of existing box type transformer:
1, due to these fixedly suspension hook all directly cut out by steel plate, with through polishing, but when lifting still can have the more sharp-pointed arm of angle because the angle of part is little, when steel wire rope rubs, easily occur disconnected strand in the above.
2, existing suspension hook is stretching out outside casing of fixing, and easily trips when operation maintenance, damages.
3, fixedly suspension hook extends, and takies volume, makes troubles to transportation.
4, each suspension hook needs staff to control steel cable and is unlikely to skid off suspension hook when being affiliated to steel wire rope.
5, in order to reduce the fixedly shared volume of suspension hook, fixedly suspension hook is generally all done to such an extent that can not be very long, but so again can be larger because of the casing of box type transformer, and on the casing eaves limit of wire line shoe at the top of casing can appear in when lifting, damage the eaves limits;
Find a relevant patent at home in the Searches of Patent Literature, number of patent application is CN201210024948.1, denomination of invention is " box type transformer dish and its lifting method for carrying ", this patent discloses and a kind ofly the lifting accessory has not been set at dish on framework, and directly hangs over according to working the steel wire rope of reusing box type transformer dish and its lifting method for carrying that the mode that just can carry out the lifting carrying on the lifting accessory that is installed on the transformer in dish has realized that structure is simplified.In box type transformer dish in transformer being accommodated in dish, transformer (2) is fixedly installed on the bottom of dish framework (1), the top board (Pan Ding) of dish (1a) one is divided into three along the left and right, arrange in the central will rise from the outside in the steel wire rope Disk of reusing and can pull down cut apart top board (1b).And, when this transformer is carried in lifting under assembled state, take off the described top board of cutting apart, then will insert from the top steel wire rope (6) in the dish directly hangs on the lifting accessory (2a) at the top that is arranged at transformer, by the operation of crane, can not apply the load-carrying of transformer and lift by crane carrying on the dish framework.But this patent does not relate to how to solve the problem that the friction of steel wire rope on the fixing sharp-pointed arm of angle of suspension hook causes steel wire rope to damage, and does not relate to yet and how to avoid steel wire rope to the damage of casing eaves.
Therefore, so there are many deficiencies in the boom hoisting of existing box type transformer.In order to prevent the damage of steel wire rope and casing eaves, necessary this is improved.
Summary of the invention
The object of the invention is to, for the deficiency of the existing anti-boom hoisting of box type transformer, proposes a kind ofly can prevent effectively that the friction of steel wire rope on the fixing sharp-pointed arm of angle of suspension hook from causing the box type transformer of steel wire rope damage to lift by crane less important work device and hoisting method thereof.
For realizing purpose of the present invention, the implementer's case that proposes is: a kind of box type transformer lifting less important work device, comprise box type transformer casing and box type transformer base, and the box type transformer casing is arranged on box type transformer base; Described box type transformer base is formed according to frame structure welding by channel-section steel, it is characterized in that, has the hanger erection hole at the major trough steel of box type transformer base, in the hanger erection hole, the scalable suspension hook of elasticity is installed.
