Abstract
Two suo shuan lamellas loading and unloading grab bucket, it articulates a set of swing arm (3) downwards respectively to go up connector (2) symmetrical both sides, go up connector (2) downside mid -mounting top sheaves (7), furthermore, articulate a bucket body (6) respectively at this two groups swing arm (3) lower extreme, the relative edge hinged of these two bucket body (6) together, on this coupling point under the side -mounting connector (5), the upper portion installation lower sheave (9) of connector (5) under, lifting rope (8) are connected in the winding between top sheave (7) and the lower sheave (9). The service life of the grab bucket prevents that lifting rope is in tensile state, extension lifting rope always is prolonged. Flexible movements are accurate, and the controllability is strong, operation easy to assemble, and simple operation safety, easy to maintain, production efficiency is high.
Description
Technical field
This utility model is related to the structure improved technology of crane gear grab mechanisms, especially double rope bivalve handling grab buckets.
Background technology
Grab bucket is the bucket to capture silt and various bulk goods can open and close.Be a kind of mainly by left and right two combination bucket or
The folding crawl of multiple jaws and the suspender drawing off bulk material.The keep left folding of right two combination buckets or multiple jaw of grab bucket is grabbed
Take and draw off the suspender of bulk material, gripper is also in the grab bucket being made up of multiple jaws.
Mechanical type grab bucket is configured without opening-closing structure in itself, is generally driven by rope or connecting rod external force, can by operating feature
It is divided into twin rope grab and single rope grab, be most commonly used that twin rope grab.
Twin rope grab has support rope and opening and closing rope, rotating around on the reel of supporting mechanism and switching mechanism.Twin rope grab
Work process：A is to support that rope and opening and closing rope decline simultaneously, opens quarrel insertion stockpile.B is to tighten up opening and closing rope, and jaw closes
And capture material.C is to support after grab bucket closes that rope and opening and closing rope rise simultaneously.D is to support that rope is motionless, and opening and closing rope declines, quarrel
Open and unload material.Twin rope grab reliable operation, easy and simple to handle, productivity ratio is high, is widely used.Just become using after two groups of duplex types
For four rope grab, work process is identical with twin rope grab.
Current grab bucket all controls opening and closure of bucket body using around the rope being located on assembly pulley, maintains it in and opens
The pulling force of open state can be constantly in tensioning state mainly by horizontal swinging arm and rope, therefore rope, if things go on like this can be right
Rope causes to damage, and shortens the service life of rope.
Single rope grab supports that restricting and be opened and closed rope uses same steel cable.Steel wire rope is made to rise in turn by special locker
To the effect supported and be opened and closed.The winding mechanism of single rope grab is simpler, but productivity ratio is low, seldom adopts during a large amount of handling operation
With.
Grab bucket is divided into according to the bulk density of crawled material that as light-duty in crawl corn, such as to capture gravel medium-sized and such as grab again
Take iron ore heavy type 3 classes；It is divided into double jaw plates grab buckets and orange-peel grab by jaw number, be most commonly used that double jaw plates grab buckets.For
Lump ore, iron filings and steel scrap etc. preferably adopt orange-peel grab, because it has the characteristics that multijaw, otch point it is easy to insertion is expected
Heap, can get preferable crawl effect.Also has a kind of scissors grab of imitative scissor construction principle, its grasp force can be with jaw
Close and be gradually increased, reach maximum when closure ends；The area of the aperture of its quarrel and covering material is also grabbed than typically
Struggle against as big, improve Grasping skill, be conducive to cleaning stock ground and cabin, but for bulk materials because its initial grasp force is little, effect
Really poor.
Utility model content
The purpose of this utility model is to provide double rope bivalve handling grab buckets.
The purpose of this utility model will be realized by following technical measures：The symmetrical both sides of upper connector are respectively articulated with downwards
One group of swing arm, under upper connector, middle side part installs pulley, further, is respectively articulated with a bucket body in this two groups of swing arm lower ends,
The opposite edges of this two bucket bodies are hinged, and connector under installing on the upside of this hinge point, on the top of lower connector
Lower sheave is installed, be intertwined and connected between top sheave and lower sheave rope.
Especially, at upper connector top, motor and hangoff receptacle are installed.
Especially, the adjacent junction edge of two bucket bodies is worked in coordination.
Especially, bucket body downside is arc shovel, upper side and leading flank hollow out.
Especially, top sheave axis, lower sheave axis and two bucket body jointed shafts are parallel to each other, and bucket body axial width is more than two
The hinged shaft length of bucket body.
Advantage of the present utility model and effect：Improve the service life of grab bucket, prevent rope to be constantly in extended state,
Extend the service life of rope.Accurately, controllability is strong for flexible movements, facilitates installation operation, simple operation safety is it is easy to tie up
Shield, production efficiency is high.
Brief description
Fig. 1 is this utility model embodiment 1 structural representation.
Reference includes：
Motor 1, upper connector 2, swing arm 3, hangoff receptacle 4, lower connector 5, bucket body 6, top sheave 7, rope 8, lower sheave
9.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：As shown in figure 1 and 2, the symmetrical both sides of upper connector 2 are respectively articulated with downwards one group of swing arm 3, upper connection

Opposite edges hinged, on the upside of this hinge point install under connector 5, the top of lower connector 5 install glide
Wheel 9, be intertwined and connected between top sheave 7 and lower sheave 9 rope 8.
In aforementioned, at upper connector 2 top, motor 1 and hangoff receptacle 4 are installed.
In aforementioned, the adjacent junction edge of two bucket body 6 is worked in coordination.After guaranteeing that lower connector 5 above carries, two bucket bodies 6 are permissible
Obvolvent completely.
In aforementioned, bucket body 6 downside is arc shovel, upper side and leading flank hollow out.
In aforementioned, top sheave 7 axis, lower sheave 9 axis and two bucket body 6 jointed shaft are parallel to each other, and bucket body 6 axial width is big
