Abstract
The invention relates to a large-span variable-capacity grab bucket which is particularly used for grabbing materials with different specific gravities, belonging to the technical field of crane equipment. The large-span variable-capacity grab bucket mainly comprises a bucket body, a connecting rod, a main rib plate, a lower bearer, an upper bearer, lifting ropes, an upper pulley wheel set, a lower pulley wheel set, a bearing balance beam, support rods and a variable-capacity plate, wherein two ends of the bearing balance beam are connected with the lifting ropes; the middle of the bearing balance beam is connected with the upper bearer in a hinging way; the two sides of the upper bearer are respectively connected with the two support rods in a hinging way; the lower ends of the support rods are articulated with the bucket body; the lower bearer is connected with the bucket body by the connecting rod; the lower bearer is connected with the connecting rod in a hinging way; and the bucket body comprises two left/right symmetrical bucket valves, and the tail end of the bucket body is connected with the variable-capacity plate. The large-span variable-capacity grab bucket is simple, compact and reasonable in structure, can realize the large-span variable capacity of the grab bucket and grabs the materials with great different specific gravities, such as coal and ore, and is high in work efficiency, so that the equipment cost can be reduced.
Description
Technical field
The present invention relates to a kind of large span transfiguration grab bucket, specifically grasp the material of different specific weight, belong to the crane facility technical field.
Background technology
Orange-peel bucket is mainly used in industries such as goods station, port machine factory, power plant, shipbuilding yard, steel mill, is used to grasp the bulk goods of various proportions.
If orange-peel bucket does not have variable bucket capacity structure, when grasping material, can't be implemented in the general of different specific weight storeroom.Such as being used for grabbing the little material of proportion with the grab bucket of grasping the great material of ore geometric ratio, efficient is seriously low; The little grab buckets of proportion such as extracting coal are used for grabbing heavy material, seriously overload.
In prior art, common transfiguration grab bucket structure is to cut off one section at original grab bucket bottom sheet tail end; Increase by one section detouchable plate again; Reach the effect of transfiguration, such transfiguration structural span is very little, can only between the close material of proportion, realize the purpose of transfiguration; The material of coal, ore geometric ratio heavy phase difference great disparity can't be used for grasping simultaneously, otherwise serious overload or inefficiency can be caused.Coal bunker and ore need two kinds of grab buckets to grasp respectively, and cost increases.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of large span transfiguration grab bucket is provided, can realize the extracting of different specific weight material, simple in structure, high efficiency has lowered equipment cost.
According to technical scheme provided by the invention; Large span transfiguration grab bucket mainly comprises bucket body, connecting rod, main gusset, through beam, deck beam, ropes, top sheave group, downslide wheels, load-bearing equalizing bar, strut and transfiguration plate; Said load-bearing equalizing bar two ends connect ropes, and deck beam is articulated and connected in the middle of the load-bearing equalizing bar.Said deck beam both sides two struts that are articulated and connected respectively, the lower end of the strut bucket body that is articulated and connected.Be connected through connecting rod on said through beam and the bucket body, through beam is connected with rod hinge connection.Said main gusset one end and through beam are articulated and connected, and the other end is connected with a plurality of connection pipes that are located at the bucket body side.
Said bucket body comprises two symmetrical bucket lobes, at bucket body end joint connection transfiguration plate.
Sheave is installed in said deck beam upper end, in deck beam, installs assembly pulley, and the downslide wheels are installed on through beam.Said top sheave group and downslide wheels include symmetrical two groups of pulleys, and two groups of pulleys of top sheave group are located on the top sheave axle by two pulley sleeves respectively, and two groups of pulleys of downslide wheels are located on the downslide wheel shaft by two pulley sleeves respectively.Said downslide wheels both sides are provided with cover of wedge.In load-bearing equalizing bar both sides the switching rope is set.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; The material of coal, ore geometric ratio heavy phase difference great disparity is grasped in can realize the grabbing bucket transfiguration of large span; High efficiency has reduced equipment cost.

The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2; The present invention mainly comprises bucket body 1, connecting rod 2, main gusset 3, through beam 5, deck beam 6, ropes 7, top sheave group 9, downslide wheels 10, load-bearing equalizing bar 11, strut 12 and transfiguration plate 18; Said load-bearing equalizing bar 11 two ends connect ropes 7, and deck beam 6 is articulated and connected in the middle of the load-bearing equalizing bar 11.Said deck beam 6 both sides two struts 12 that are articulated and connected respectively, the lower end of strut 12 bucket body 1 that is articulated and connected.Be connected through connecting rod 2 on said through beam 5 and the bucket body 1, through beam 5 is articulated and connected with connecting rod 2.Said main gusset 3 one ends and through beam 5 are articulated and connected, and the other end is connected with a plurality of connection pipes 17 that are located at bucket body 1 side.
Said bucket body 1 comprises two symmetrical bucket lobes 4, at bucket body 1 end joint connection transfiguration plate 18, according to the material of different specific weight, changes the transfiguration plate 18 of differing heights.
Sheave 13 is installed in said deck beam 6 upper ends, in deck beam 6, installs assembly pulley 9, and downslide wheels 10 are installed on through beam 5.Said top sheave group 9 includes symmetrical two groups of pulleys with downslide wheels 10, and two groups of pulleys of top sheave group 9 are located on the top sheave axle 15 by two pulley sleeves respectively, and two groups of pulleys of downslide wheels 10 are located on the downslide wheel shaft 16 by two pulley sleeves respectively.Said downslide wheels 10 both sides are provided with cover of wedge 14.Switching rope 8 is set in load-bearing equalizing bar 11 both sides.
