Description
Technical field
A kind of method that the present invention relates to marine main engine lifting, particularly a kind of marine main engine cylinder block and air cooler integral hoisting bracket and method, belong to ship building technical field.
Background technology
The main frame of boats and ships will be lifted on building berth and install completing after manufacture, and for the heavy main frame of large ship, its lifting and transport are exactly a difficult job.Because the air cooler of main frame and auxiliary blower assembly are positioned at the below of cylinder band, and they do not have the unified plane of landing, and existing transportation means cannot meet the needs of both integral transportation thus.Existing way can only disassemble independent transport by air cooler from main frame at heavy-duty machine assembly shop, is assembled after having arrived general assembly scene by general assembly department again.While assembling due to both, taking the height time of hanging grows (at least 2 hours), and field operation workman is more, has increased personal safety hidden danger; In addition, air cooler is dismantled with dress and resumed a session and affect the leak tightness of contact surface between the two, cause scavenging to leak, also can cause rubbish to enter the hidden danger of air cooler inside simultaneously.
Summary of the invention
The object of the invention is to overcome the deficiency that above-mentioned prior art exists, a kind of marine main engine cylinder block and air cooler integral hoisting bracket and method are provided, the integral hoisting transport to realize main frame air cooler and auxiliary blower assembly and cylinder block not to dismantle, thus improve handling appliance service efficiency, ensure main frame assembly quality, reduce labor strength and reduce the potential safety hazard of field operation.
The present invention solves its technical matters by the following technical programs:
A kind of marine main engine cylinder block and air cooler integral hoisting bracket, be connected in the bottom surface of described cylinder block, it comprises base plate, both sides panel, some pipe links, some gussets, two top panels and two hangers, described both sides panel relatively stands on base plate and with it and fixes, described some pipe links are laterally fixedly connected between the panel of both sides, described some gussets stand on the outside of both sides panel symmetrically, and be fixedly connected with both sides panel with base plate, described two top panels respectively on even keel are arranged at the upper end of both sides panel, and be fixedly connected with both sides panel with gusset respectively, described two hangers are fixedly connected on the top of the gusset of both sides symmetrically.
Described bracket all adopts steel to be welded.
Another technical scheme of the present invention is:
Marine main engine cylinder block and the air cooler integral hoisting method realized by described bracket, it comprises the steps:
1. when main frame disintegrates, cylinder block and air cooler fabricate block are placed on described bracket;
2. main frame cylinder block lower plane is made to oil sealing and also wait ready for delivery;
3. by main frame cylinder block and air cooler fabricate block together with bracket Integral lifting to flat truck;
4. after being transported to building berth, on flat truck, main frame cylinder block lower plane being deoiled and seals and clean;
5. cylinder block and air cooler fabricate block being winched to the luggage of going forward side by side on main frame joins.
Advantage of the present invention and useful technique effect are as follows:
1, will air cooler when main frame disintegrates in internal field under cylinder block disintegrates, ensured the sealing requirements between scavenging box and air cooler, also avoided the possibility that in disintegration process, rubbish enters air cooler inside simultaneously; In addition, reduced making oil sealing and deoiling envelope clean work capacity in the future of main frame cylinder block and air cooler contact surface.
2, adopt after bracket, main frame cylinder block and air cooler can overall shippings, reduced transportation one time.
3, main frame cylinder block lower plane deoils and seals and clean and can directly on flat truck, carry out, and meanwhile, plays heavy industry lifting appliance for hoisting can be installed, thereby greatly shorten the lifting time.
4, save main frame cylinder block and the assembling process of air cooler before upper hull in the past, greatly improved high service efficiency of hanging the labour intensity that has reduced workman.
