Abstract
The utility model relates to a grab. More specially, the utility model relates to a bulk grab with a novel structure to essentially solves the technical problem of a high difficulty of grab manufacture and maintenance. The technic proposal of utility model detailed as follows: A bulk grab comprises an upper pulley blocks, a supporting rod, a grab enclosure and a medium horizontal beam, wherein the upper section of the supporting rod is fixed on the upper pulley blocks; the lower section of the supporting rod is fixed on the grab enclosure. The utility model is characterized in that a plurality of connection holes of upper section of two supporting rods respectively at two sides are respectively fixed on two ends of a main shaft of the upper pulley blocks. The supporting rod, fixed at the same side of the end of main shaft of the upper pulley blocks, has a staggered installation with certain spacing. Two groups of two shears plates are respectively fixed at two ends of the upper section at the enclosure side of the grab; a connection hole positioned at the upper section of shear plate is sleeved into a stationery shaft positioned at two ends of the medium horizontal beam which is positioned below the upper pulley blocks and equipped with a lower pulley blocks fixed at the upper surface of the medium horizontal beam. The upper and lower ends of supporting rod all have a bend; the lower end is equipped with a connection hole to have a hinge connection with a support of supporting rod positioned at two sides of the grab enclosure. The utility model is essentially used for loading and unloading the bulk at a port and a yard with a loading and unloading capacity from 10 to 16 tons.
Description
Technical field:
The utility model relates to a kind of grab bucket, particularly a kind of bulk cargo of new construction grab bucket.
Background technology:
The common structure top sheave of grabbing bucket partly adopts a sheave shaft 11, and straight strut 12 adopts homonymy to use the frame mode of a strut anchor shaft 10, three axles are formed mechanism's (see figure 3) in a very little space, in order to guarantee normal use, the mutual alignment tolerance height of three axles, the complex structure volume is big, manufacturing cycle is long, the expense height, and parts are need repair the time, very high to technical requirements, be unfavorable for the maintenance of use department.The processing axis hole directly is connected with center member on the bucket shell, and mutual restriction during maintenance has increased work capacity and maintenance time.
Summary of the invention:
The purpose of this utility model provides a kind of bulk cargo grab bucket of new construction, mainly solves former grab bucket manufacturing and the big technical matters of maintenance difficulty.
Technical solutions of the utility model are: a kind of bulk cargo grab bucket, comprise top sheave group, strut, grab bucket bucket shell, center member, the strut upper end is fixed on the top sheave group, the strut lower end is fixed on the grab bucket bucket shell, it is characterized in that, the upper end connecting bore of each two strut of both sides is separately fixed at the two ends of top sheave group main shaft, is fixed on top sheave group spindle end and is staggered installation at regular intervals with side brace.Be fixed with two groups of each two blocks of scissors plates respectively in grab bucket bucket shell-side both upper ends thereof, scissors plate upper end connecting bore is socketed on the two ends anchor shaft of center member, and center member is positioned at top sheave group below, is fixed with the downslide wheels at the upper surface of center member.All there is bending strut upper end and strut lower end, and the strut lower end has connecting bore hinged with the strut bearing that is fixed on grab bucket bucket shell both sides.
The beneficial effects of the utility model are: the utility model staggers the strut of top sheave group homonymy mutually, and grazing can not take place, and can effectively finish the opening and closing of grab bucket.Grab bucket bucket shell adopts split to be connected with center member, has made things convenient for Maintenance and Repair.Coaxial configuration is adopted in the hole on top sheave and four struts, and parts significantly reduce, and volume can dwindle, and stress point is focused on the axle by three places.The utility model machined piece reduces, compact overall structure, and weight can reduce, and has improved extracting efficient.The maintenance rapid and convenient, making and operating costs are low.At different material, under the prerequisite that does not change manufacture craft, only need to change the relative dimensions of bucket shell and center member, can making place grasp the grab bucket of different material.The utility model is applicable to powdery, the lump material of proportion 0.5～3.5.
Description of drawings:

Fig. 2: the utility model structural representation left view
Among the figure: 1-top sheave group, 2-strut, 3-downslide wheels, 4-center member, 5-grab bucket bucket shell, 6-scissors plate, 7-main shaft, 8-anchor shaft, 9-strut bearing.
Fig. 3: common grab bucket top sheave group structural representation
Among the figure: 10-strut adapter shaft, 11-sheave shaft, the straight strut of 12-.
The specific embodiment:
With reference to accompanying drawing 1,2, bulk cargo is grabbed bucket by top sheave group 1, grab bucket strut 2, and downslide wheels 3, center member 4, grab bucket bucket shell 5, the major part of scissors plate 6 and assembly are formed.All there is bending strut 2 top and bottom, and the upper end connecting bore of each two strut 2 of both sides is separately fixed at the two ends of top sheave group main shaft 7, are fixed on top sheave group main shaft 7 ends and are staggered installation with side brace 2, with being provided with spacer ring between side brace 2 upper end connecting bores.Strut 2 lower end connecting bores are hinged with the strut bearing 9 that is fixed on grab bucket bucket shell both sides.Be welded with two groups of each two blocks of scissors plates 6 respectively in grab bucket bucket shell-side both upper ends thereof, scissors plate 6 upper end connecting bores are socketed on the two ends anchor shaft 8 of center member 4, and center member 4 is positioned at top sheave group 1 below, are fixed with downslide wheels 3 at the upper surface of center member 4.Since adopt strut at homonymy bucket shell in the top sheave group with the outside or with inboard connection mode, can guarantee that connecting bore uses same axis on the strut because all there is bending strut 2 top and bottom, more help finishing the opening and closing of grab bucket.Grab bucket bucket shell does not use integral structure, makes main abrading section independently become parts, can effectively reduce the frequency of maintenance of major part center member and bucket shell, prolongs its service life.Major part uses the 2mm thin plate to make template, makes the parts production standardization, is convenient to fairly large production.The bulk cargo grab bucket of bucket shell width 1.5m is applicable to iron ore, and Iron Ore Powder etc. are greatly than heavy material, and the bulk cargo grab bucket of bucket shell width 1.8m is applicable to the little heavy materials that compare such as coal, stone flour and coke.
It is short to design and produce the bulk cargo fabrication cycle more than the employing, and cost is low, and maintenance is convenient, quick, can be applicable to the bulk cargo loading and unloading in harbour and the stock ground of 10～16T.
