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 by the row's of hanging main structure, pulley system, additional strengthening and connecting bridge are formed, the row's of hanging main structure is by web, end plate, top board, base plate, sister block hanger in the sister block axle is welded, two blocks of webs are positioned at the row of hanging two sides, top board is installed in the web inboard, be positioned at and hang row of horizontal line of centers top, under the suspension hook, base plate is installed in the web inboard, be positioned at and hang row of horizontal line of centers below, 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 both sides under the base plate in the sister block axle, with the row's of hanging sister block axis hole concentric; Described pulley system comprises sister block system and single pulley system.
Two pulleys of the sister block system in the pulley system are installed in sister block hanger place, the central shaft hole of pulley and hanger axis hole concentric, and pulley and sister block hanger are linked and packed by sheave shaft, copper sheathing, small semicircle cover, roundlet cover, screw, lubricating cup; The pulley of the single pulley system in the described row's of hanging the pulley system is installed in the row of hanging single-sheaved block hanger place, pulley axis hole and single-sheaved block hanger axis hole concentric, pulley and single-sheaved block hanger are linked and packed by sheave shaft, copper sheathing, steel bushing, small semicircle cover, roundlet cover, screw, lubricating cup.
The row's of hanging additional strengthening is made up of big gusset, upper ear plate liner, big gusset, middle gusset, small gusset, little liner plate, big liner plate, weld pad, hanger liner plate, and described big gusset fits in two web outside tops; The upper ear plate liner connects upper ear plate liner axis hole and shackle shaft axis hole concentric with the suspension hook hanger outside; Big gusset is installed on the web inboard, is positioned at sister block hanger root; Middle gusset is installed on the base plate inboard, is arranged in sister block axle sister block hanger top; Small gusset is installed on the web inboard, is positioned at single-sheaved block hanger root; Little liner plate is installed on sister block hanger inboard, near the hanger root; Big liner plate is positioned at suspension hook hanger inboard, near suspension hook hanger root; Pad installation is in web outside, with pulley hanger axis hole concentric; The hanger liner plate is installed on single-sheaved block hanger inboard.
The row of hanging is made up of shackle shaft, spacing pad, stop washer, roundlet nut with the connecting bridge of suspension hook, described shackle shaft is connected with the suspension hook hanger by stop washer, little circular nut, with the axis hole concentric, spacing pad is installed on suspension hook hanger inboard, with suspension hook axis hole concentric.
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.
