Description
Technical field
The present invention relates to ship building, particularly relate to a kind of lifting device of being used for mounting shipping rudder system in the ship building and based on the hanging method of this lifting device.
Background technology
At present the hanging method of shipping rudder system lining is that to fasten rudder with rope be lining, and it is freezing to put into liquid nitrogen then, is that lining is packed in rudder hole and the rudder pintle hole by manpower with the rudder after freezing subsequently.Adopt this hanging method, though can be packing into of lining safety with rudder finally, level of mechanization be too low, can't guarantee fully in the hoisting process, and rudder is the landing of lining and collides other objects to cause rudder be scratch of lining etc.
In above-mentioned hanging method, rudder is that the lifting of lining is to use manual manipulation by the workman, and the rudder behind the liquid nitrogen frozen is a lining has very big threat to workman's personal safety, and danger coefficient is very high.Because adopting rope binding rudder is the method for lining, when rudder is that lining lifts place, rudder hole, also need remove rope, not only increased work capacity, and in narrow space, operate, rudder is that the integraty of lining and workman's personal safety all can not get strong assurance.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, provide a kind of lifting device that is used for mounting shipping rudder system and based on the hanging method of this lifting device.Tool and method of the present invention reduces working strength of workers in order to improve the safety that rudder is the lining lifting, and the whole rudder of powerful guarantee is the quality of lining lifting again simultaneously, and then shortens cycle of operations, and this instrument also will have commonality in addition.
In order to reach the foregoing invention purpose, the invention provides following technical scheme:
Rudder is the lifting device of lining on a kind of boats and ships, it is characterized in that, this lifting device includes body frame, three corner steady, expansion plate and suspension ring, two long bolts that described body frame includes mobile jib and is fixed in these mobile jib two ends, described tripod fixed mount comprises the sleeve pipe that is positioned at the middle part, evenly be fixed on three heart grooves on the sleeve pipe, the expansion link that described expansion plate comprises one section arc and is fixed in the arc middle part, described expansion link stretches into heart groove telescopically and fixes; One three corner steady and three expansion plates are combined as clamp structure, two clamp structures are fixed in the two ends up and down of body frame by long bolt and nut, the clamp structure pad that is positioned at the lower end is a sleeve in rudder, it is the lining top that clamp structure on being positioned at places rudder, is screwed with suspension ring on the long bolt on described body frame top.
In the present invention, be to be provided with cushion block between the lining at described clamp structure and rudder, above-mentioned cushion block generally is welded on the expansion plate in the clamp structure.
A kind of to utilize above-mentioned lifting device be the method for lining lifting to rudder on the boats and ships, it is characterized in that this method comprises the steps:
1. preliminary combined hanging instrument, measuring rudder to be lifted is the lining external diameter, is that the lining specification is combined into two clamp structures with two three corner steady and six expansion plates according to rudder;
2. welding a cushion block respectively at the expansion plate two ends, is the external diameter of lining again according to rudder, adjusts the length of expansion plate, and making cushion block can be attached to rudder is on the lining, will extend into expansion link in the heart groove with bolt of rear end plate and tighten with fixing expansion plate;
3. the long bolt that is positioned at the mobile jib lower end on the body frame being screwed into place in the sleeve pipe of bottom clamp structure, is the height that the height of lining is tentatively adjusted body frame according to rudder, is that lining is placed on six cushion blocks on the clamp structure of bottom with rudder;
4. the top clamp structure being put into rudder is on the lining, and the long bolt that is positioned at mobile jib upper end passes the sleeve pipe of top clamp structure and by using nut screwing clamping, six cushion blocks on the clamp structure of top are affixed on the upper limb that rudder is a lining;
5. described suspension ring are screwed into place on the long bolt of mobile jib upper end, hang with crane that to draw lifting device and the rudder combined be lining;
6. utilizing crane and lifting device earlier is that lining hangs in the liquid nitrogen with above-mentioned rudder, place a period of time after, it is to fix among being placed directly into the rudder hole of boats and ships behind the lining that crane hangs out rudder in the liquid nitrogen;
7. treat that above-mentioned rudder ties up to after the rudder hole internal fixation of boats and ships, pulls down above-mentioned lifting device.
Based on technique scheme, lifting device of the present invention and hanging method have following technological merit with respect to prior art:
1. it is the characteristics of lining and designing that lifting device of the present invention is directed to rudder, this later-model frock part is to be that bush inside is fixed from rudder, convenient directly hanging in the rudder hole, replace the secondary adjustment of tradition lifting, also just avoided the deficiency of secondary adjustment because of the space, the potential safety hazard and the rudder that bring to the workman are the let-in difficulty of lining.But also improved rudder greatly is the safe reliability of lining lifting, this frock part can level and vertical direction completely fixedly rudder be lining, prevent that rudder from being the slippage of lining, and the direction of crane can be handling, controlling rudder fully is the whole hoisting process of lining, improves safety factor.Instrument of the present invention can be the external diameter of lining and highly come real-time regulated, be lining thereby intactly fix described rudder according to rudder.And method of the present invention is to guarantee at the hoisting process centered rudder to be that lining can not be moved in level and vertical direction, can guarantee that like this rudder is that lining is guaranteed setting accuracy in freezing and installation process.
2. it is that lining absorbs heat in atmosphere that lifting device of the present invention can also reduce rudder, and the possibility of premature expansion prevents that rudder from being that lining because of unbalance stress deformation takes place.In addition, adopt method of the present invention and lifting device to carry out the lifting of shipping rudder system lining, it is lining that the workman only needs this frock part is fixed rudder.With crane replace manpower to steer being lining put into liquid nitrogen and freezing after lifting.Not only guaranteed the lifting quality, and improved workman's working environment, avoided the workman, alleviated working strength of workers greatly by the possibility of liquid nitrogen frostbite, as safe as a house reliable.
