Abstract

Disclosed is a hanging row which comprises a plurality of crown blocks symmetrically arranged on two side faces of a girder, rotating shafts of the plurality of crown blocks of each side face are positioned on the same horizontal plane, and the plurality of crown blocks are positioned in the same vertical plane; jacking blocks fixedly connected with side faces thereof are disposed between the two crown blocks and the outer sides of the crown blocks at both ends respectively, and a pulley is disposed below each jacking block; the crown blocks and the traveling blocks are connected with one another in a bypassing way sequentially and continuously from one end through a main rig, and both ends of the main rig are fixedly connected with the girder; the pulleys are connected with shackles by ropes; and two-lug plates fixedly connected at both ends of the girder are fixedly connected with a lifting hook of a traveling crane by main pin shafts. The hanging row adopts a single rope at both sides of the girder to connect the plurality of crown blocks and the pulleys into one body, each pulley has the equal stress when lifting an object, so the object will not incline easily when being lifted, and the operation is safe and reliable. The plurality of pulleys can be selected at will, and the selection range of space between lifting points is rather large, so as to adapt to the lifting of objects with different sizes and shapes.

Description

The row of hanging

Technical field

The utility model relates to a kind of row of hanging, and belongs to load and hangs hoisting device, is specially adapted to large-scale hull segmental hoisting and starts shipment.

Background technology

The row of hanging of body section lifting usefulness installs several coasters respectively in the both sides of girder in the large ship manufacturing at present, and the quantity of coaster is limited, thereby but the lifting point spacing of suspension hook is fixed, select the position and the quantity of lifting point all to be restricted, but the size and the shape of suspended object are ever-changing, so very inconvenient during lifting job, efficient is low.Captive joint with girder by rigging respectively because of each coaster again, thus each Heave Here discontinuity, make phenomenons such as suspended object run-off the straight easily, cause safety misadventure.

The utility model content

The technical problems to be solved in the utility model provides a kind of simple in structure, adopts single main rope tool, makes that a plurality of suspension hook coasters are stressed to be equated, suspended object is difficult for run-off the straight, the safe and reliable row of hanging.

The utility model hangs row, comprises girder, and several fixed pulleys wherein are housed on the two sides of girder symmetrically, and the rotating shaft of several fixed pulleys of each side is positioned on the same horizontal surface, and several fixed pulleys are positioned at same perpendicular; On each side, between two fixed pulleys, be respectively equipped with the jacking block of captiveing joint with its side with the fixed pulley outside at two ends, below each jacking block, be provided with coaster; Coaster comprises movable pulley, and movable pulley is by the top of upper pin rotational fixation between two parallel splints, and two clamping plate upper end strides across the movable pulley captive joint and be integral, and two clamping plate bottoms are by the lower bearing pin captive joint; From the end flexible connection of detouring continuously successively, captive joint with girder by pullover in the two ends of main rope tool by the main rope tool for fixed pulley and movable pulley; Lower bearing pin is connected with shackle by rope; The two ends of girder are provided with the ears plate that perpendicular crosswise fixed connects and is parallel to each other, and the ears plate is captiveed joint with the suspension hook of driving by the stub axle.

The utility model hangs row, and the clamping plate bottom of mutual cooresponding two coaster inboards connects by spending blue screw rod secured in parallel on the two sides of its middle girder.

The utility model hangs row, and wherein the lower surface of several jacking blocks on each side at grade.

The utility model hangs row, wherein on girder, be provided with captive joint with it hang horse for a short time.

The utility model hangs row, wherein is provided with the reinforcement gusset on the otic placode of the outside of ears plate, is provided with carriage on the inboard otic placode of ears plate.

The utility model hangs row, wherein is provided with to protect on the girder two ends and blocks.

The utility model hangs row and has following advantage: 1, adopt single rigging by several fixed pulleys several coasters of bottom to be fused on the both sides of girder, the stressed of each coaster equates when the lifting suspended object.2, several coasters can be chosen arbitrarily, promptly lifting during suspended object the lifting point spacing to choose scope bigger, adapt to the lifting of different sizes, difform suspended object.3, each lifting point is stressed equates, thereby during the lifting suspended object, is difficult for run-off the straight, and the handling safety of operation is reliable.

The specific embodiment

By Fig. 1, Fig. 2 as seen, the utility model hangs package and draws together girder 1, several fixed pulleys 2 wherein are housed on the two sides of girder 1 symmetrically, and the rotating shaft of several fixed pulleys 2 of each side is positioned on the same horizontal surface, and several fixed pulleys 2 are positioned at same perpendicular; On each side, between two fixed pulleys 2, be respectively equipped with the jacking block 3 of the captiveing joint (hollow square that is welded into by multi-sheets with its side with fixed pulley 2 outsides at two ends, as shown in Figure 3, Figure 4), and the lower surface of several jacking blocks 3 on each side at grade.Below each jacking block 3, be provided with coaster, this coaster comprises movable pulley 4, movable pulley 4 is by the top of upper pin 5 rotational fixation between two parallel splints 6, and two clamping plate, 6 upper ends stride across movable pulley 4 captive joints and be integral, and two clamping plate, 6 bottoms are by lower bearing pin 7 captive joints; From the end flexible connection of detouring continuously successively, captive joint with girder 1 by pullover in the two ends of main rope tool 8 by main rope tool 8 for fixed pulley 2 and movable pulley 4; Lower bearing pin 7 is connected with shackle 10 by rope 9; The two ends of girder 1 are provided with the ears plate 11 that perpendicular crosswise fixed connects and is parallel to each other, and ears plate 11 is captiveed joint with the suspension hook 13 of driving by stub axle 12.

Clamping plate 6 bottoms of cooresponding two coaster inboards are by spending blue screw rod 14 captive joints mutually on the two sides of its middle girder 1, and as shown in Figure 4, this spends blue screw rod 14 two ends all can regulate, and makes the free state of the coaster keeping parallelism on the two sides.On the otic placode of the outside of ears plate 11, also be provided with and strengthen gusset 16, on the inboard otic placode of ears plate 11, be provided with carriage 17, put stub axle 12 when being convenient to, because this stub axle 12 is not only thick but also heavy with travelling crane hook 13 installing/dismountings.

Be provided with to protect on the two ends of girder 1 and block 18, weigh because girder 1 is big, the installing/dismounting personnel need aloft work on beam, protects to block 18 and have the safety precaution effect.On girder 1, be provided with captive joint with it hang horse 15 for a short time, be used for being connected with other lifting appliances, finish installation exercise.

The utility model hangs when coming lifting operation, elder generation is according to the situation of suspended object, select cooresponding many to coaster, infratrochlear shackle 10 is connected securely with suspended object, start driving, at this moment upwards do not contact motionless with cooresponding jacking block 3 with suspended object bonded assembly coaster, do not load under these coasters and do not stress, lifting operation is finished, again by the operation of driving completion bit shifting movement in the position of all the other coaster automatic compensations and relative fixed pulley.
