Abstract
The invention relates to a large tonnage reactor truck loading jacking technique which is characterized by comprising the following steps: (1) confirming the number of hoisting frames according to the weight of a reactor; (2) evenly distributing the hoisting frames under the reactor; (3) fixing jacks inside support seats and then arranging at the two ends of the hoisting frames, and respectively arranging one jack at the two ends of each hoisting frame; (4) when the jacks work, leading the support seats to be lifted at the same height together with the jacks, padding wood beams under the support seats at the time, and then padding the wood beams under pistons after the jack pistons are withdrawn; and (5) when a transport flat truck is driven under the hoisting frames, withdrawing the jacks by utilizing the self lifting function of the flat truck to complete the whole truck loading work. The large tonnage reactor truck loading jacking technique can realize delivery and dispatch of the overweight reactor in the factory, thus reducing the manufacturing cost of the product. At present, the technique can realize jacking and truck loading of the reactor having the weight within 200t in the factory.
Description
Technical field
The invention belongs to a kind of lifting technology.
Background technology
The large-tonnage reactor is owing to be subjected to the restriction of the existing overhead traveling crane load-carrying ability of factory, can not finish whole manufacturing work in factory, reactor transports segmentation to user's erecting stage, and carry out assembly welding, heat treatment, flaw detection, water test, application at the scene, finally pay the user, cause the waste of manpower, goods and materials, fund, increased the manufacturing cost of product.
Summary of the invention
The object of the invention provides a kind of method of large tonnage reactor truck loading jacking, can realize the shipping of delivering goods of overweight reactor in factory, thereby reduce cost of goods manifactured.
The technical scheme that the present invention is adopted for achieving the above object is:
A kind of large tonnage reactor truck loading jacking technique is characterized in that: may further comprise the steps:
(1), determines that lifting lifts the quantity of frame according to the weight of reactor;
(2) lifting is lifted frame and be distributed on the reactor below;
(3) jack is fixed in the bearing, places lifting to lift the frame two ends then, each lifting is lifted the two ends of frame and is respectively placed 1 jack;
(4) in jack when work,, bearing is also together with the jack identical height that rises, flitch on the bearing underlay at this moment, flitch on the piston underlay again after jack piston is regained;
(5) dollie reaches lifting and lifts below the frame, utilizes the elevating function of flat truck self, jack can be spread out, and finishes whole entrucking work.
The jack that all liftings are lifted under the frame is controlled with a Hydraulic Station.；
Described lifting is lifted frame and is provided with two bearings, and the garden arc radius of bearing inboard is identical with the reactor of institute's jacking.
Be provided with branch lotus plate below the described bearing.
The centre, below of described bearing has square hole, jack piston rod down, piston rod can reach the outside of bearing.
Described flitch buttress sign indicating number becomes cribwork.
The invention has the beneficial effects as follows: the method for large tonnage reactor truck loading jacking, can realize the shipping of delivering goods of overweight reactor, thereby reduce cost of goods manifactured in factory.We can realize 2000 tons with the jacking entrucking in factory of interior reactor at present.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the shelf structure scheme drawing is lifted in lifting;
Fig. 3 is a scheme drawing before the jacking;
Fig. 4 is a scheme drawing after the jacking.
Among the figure: 1, divide the lotus plate; 2, reactor; 3, jacking bracket; 4, frame is lifted in lifting;
5, flitch; 6, bearing.
The specific embodiment
Shown in Fig. 1-4, a kind of method of large tonnage reactor truck loading jacking, according to the weight of reactor, determine that lifting lifts the quantity of frame 4, frame 4 is lifted in lifting all be arranged in the reactor below, each lifting is lifted the two ends of frame 4 and is respectively placed 1 jack, divide lotus plate 1 to place following (if the ground loading ability meets the demands, can divide the lotus plate) of jacking bracket 3, jack is fixed in the jacking bracket 3 in advance, control all liftings with a Hydraulic Station and lift jack under the frame, carry out synchronization of jacking up.Every jack is separately fixed at 3 li of jacking brackets, jack piston rod down, during jack work, in the time of each jacking, jacking bracket 3 is also together with the jack identical height that rises, flitch on jacking bracket 3 underlays at this moment, flitch on the piston underlay again after jack piston is regained, repeat above action (the flitch sign indicating number becomes cribwork), arrive till the desired top lifting height.Dollie reaches lifting and lifts below the frame, utilizes the elevating function of flat truck self, jack can be spread out, and finishes whole entrucking work.
When frame 4 is lifted in the design lifting, require lifting to lift the reactor that frame 4 can adapt to different-diameter, consider not waiting of reactor diameter, weight, each lifting is lifted frame by different load capacity designs, and lift in lifting and to design two bearings 6 on the frame 4, the garden arc radius of bearing 6 inboards is identical with the reactor of institute's jacking, as long as change two bearings 6, just can adapt to the jacking operation of different-diameter reactor.In addition, the design of bearing 6 has also improved the stressed distribution that frame is lifted in lifting, has reduced own wt and manufacturing cost that frame is lifted in lifting.
Jacking bracket 3 is to be used for jack is fixed on the inside, during jacking, jack piston rod down, the centre, below of jacking bracket 3 has square hole, piston rod can reach the outside of jacking bracket 3, during the jack jacking, jacking bracket also rises together.
