Description
Technical field
The present invention relates to a kind of weight-lifting equipment, relate in particular to the special-purpose lifting equipment of gauntry crane in a kind of shipbuilding industry.
Background technology
Lifting equipment has been the specialized equipment of reusing gantry driving, plays the increase suspension centre, optimizes the effect of flexible steel wire stressing conditions.
Ship-related products need to carry out segmentation in manufacture process divides, and carries out general assembly then.Need to be shifted and to stand up in the manufacture process of segmentation, this type of need of work relies on hoisting crane to finish.For the handling that makes segmentation and stand up safe and reliablely, some suspension centres need be set rationally.For guaranteeing that flexible steel wire correctly connects suspension centre and weight-lifting equipment, need to install lifting equipment.
Publish by National Defense Industry Press, " the hull workshop manual " the 896th page of " " hull workshop manual " writes group " establishment, 3.11.6 saves the row of hanging that discloses a kind of medium texture type in " draw-beam (hanging beam) ".Its structure is: " being the equal strength i-shaped beams of variable section, and having bracket and level to prevent turning round plate, is a kind of typical structure of draw-beam.It is reliable convenient, rational in infrastructure to use, but makes trouble." its purposes is: " and handling parts, panel and light-duty flat section, applied widely.Usually hoisting capacity all can be used at the various segmentations below 30 tons, panel.”
Publish by National Defense Industry Press, " the hull workshop manual " the 897th page of " " hull workshop manual " writes group " establishment, 3.11.6 saves the row of hanging that discloses a kind of heavy type structure type in " draw-beam (hanging beam) ".A kind of row of hanging of heavy type structure type, its structure is: " a kind of box type construction commonly used cooperates double hook to use.The following hook that has is only established two, and is removable.Complex structure." its purposes is: " be used for heavy segmentation or large-scale panel.Use occasion is few.”
The row of hanging of this type of structure type can not satisfy the big segmentation production demand of shipbuilding, and its shortcoming is: it is too small to play heavy lift, and it is bigger to conduct oneself with dignity, and uses inconvenience, bigger to the wearing and tearing of flexible steel wire, causes the flexible steel wire consumption bigger, has potential safety hazard.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, it is big to propose a kind of load-carrying ability, has pulley gear to improve the lifting equipment of steel wire stressing conditions.Serial problems such as row's deadweight, raising load-carrying ability, the loss of minimizing steel wire are hung in solution.
In order to achieve the above object, the following technical scheme of employing of the present invention:
Device of the present invention is made up of the row's of hanging main structure, pulley system, additional strengthening and connecting bridge, and major part comprises: hanger, small gusset, packing ring, big liner plate, weld pad, steel bushing, hanger liner plate, stop washer, little circular nut, screw, lubricating cup in web, end plate, big gusset, upper ear plate liner, hanging axis, top board, big gusset, middle gusset, base plate, little liner plate, pulley, copper sheathing, spacing pad, small semicircle cover, roundlet cover, sheave shaft, the sister block.
The described row of hanging main structure is welded by hanger in web, end plate, top board, base plate, the sister block axle, two blocks of webs are positioned at the row of hanging two sides, and top board is installed in the web inboard, are positioned to hang row of horizontal line of centers top, near the suspension hook hanger, base plate is installed in the web inboard, is positioned to hang row of horizontal line of centers below, near the sheave shaft hanger, two end plates is installed in the web inboard, be positioned at the row's of hanging both ends of the surface, hanger is installed in plate outer side in the sister block axle, with the row's of hanging sister block hanger axis hole concentric; Described pulley system comprises sister block system and single pulley system.
The invention has the beneficial effects as follows: designed the satisfied 300 tons of drivings of heavy lift and hung row's demand; Weight reduction improves the actual load-carrying ability of driving; The design of pulley system makes the wearing and tearing of steel rope effectively slow down; During handling, steel rope is stressed to be optimized.
The use of the row of hanging can reduce the subtended angle of steel wire, makes steel wire stressed evenly, thereby reduces subsection deformation, has guaranteed the quality of segmentation.Reasonably suspension centre setting makes whole handling work safety, reliable, guarantees segmentation quality and safe lifting.
The row of hanging can make shackle, wire gauge reduce after using, and reduces steel wire loss and segmentation and strengthens, and prolongs the steel wire life-span, accelerates the shipbuilding progress.In addition, reinforcement material is saved in the reinforcement of segmentation in the time of can also reducing handling and mounting or dismounting are artificial, reduces labor strength, enhances productivity, and shortens shipbuilding period, and this techno-economic effect is long-term benefiting.
