Description
Technical field
The utility model relates to grab bucket field, relates in particular to the Simple interchangeable structure of a kind of machinery grab bucket three or four multiplying powers.
Background technology
Grab bucket uses comparatively general a kind of bulk handling device in the carrier such as port and pier, power plant, as everyone knows, grabbing bucket, it is made up of bucket lobe, deck beam and fixed pulley group, cross sill and running block, strut, sheave, equalizer bar, steel rope etc.Due to the difference of grab multiple, in assembly pulley, include the pulley of different number.Steel rope makes bucket lobe close by the drive of pulley and opens.
In prior art, grab bucket is all the grab bucket choosing different multiplying for different material, these are many for crawl material variety, the grab bucket use occasion that often kind of inventory is few, cause grab bucket kind many, often kind of grab bucket degree of utilization is not high, and grab bucket maintenance and management cause difficulty, and manpower and materials all produce meaningless waste.
Utility model content
For the problems referred to above, the utility model provides the Simple interchangeable structure of a kind of machinery grab bucket three or four multiplying powers, to solve the problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
The Simple interchangeable structure of machinery grab bucket three or four multiplying powers, it is characterized in that, deck beam is built with top sheave group, top sheave group is installed on top sheave axle, top sheave group comprises two pieces top sheave in a symmetrical arrangement, deck beam is provided with two groups of corresponding with two pieces top sheave position respectively deck beam covers of wedge and messenger is taken turns;
Through beam is built with downslide wheels, and downslide wheels are installed on downslide wheel shaft, and it is in a symmetrical arrangement that downslide wheels comprise four lower sheaves, and outside through beam, bolster cover of wedge is respectively welded on both sides.
In the utility model, two groups of guide rope devices are installed on the top of deck beam.
Use the steel rope mounting means of three multiplying powers: if capture the material easily captured, in order to the work efficiency improving grab bucket then adopts the steel rope mounting means of three multiplying powers.Opening and closing rope enters a lower sheave in the middle of downslide wheels, then lays out from the other end of lower sheave the top sheave entered top sheave group, then lays out from the other end of top sheave and enter through beam cover of wedge.
Use the steel rope mounting means of four multiplying powers: if capture the material being difficult to capture, in order to the bucket fill degree improving grab bucket then adopts the steel rope mounting means of four multiplying powers.Opening and closing rope enters a lower sheave in the middle of downslide wheels, the top sheave entered top sheave group is laid out again from the other end of lower sheave, the lower sheave entered outside downslide wheels is laid out again from the other end of top sheave, lay out from the other end of lower sheave the messenger wheel entered deck beam again, enter deck beam cover of wedge through messenger wheel.
The utility model can realize the Simple interchangeable of opening and closing steel rope three or four multiplying power, to the demand that the opening and closing moment needed for satisfied crawl different specific weight material is different.
The utility model can adjust the mounting means of steel wire rope of grab bucket according to the demand capturing material, without the need to changing grab bucket, reducing waste and the redundancy of grab bucket, improve grab bucket degree of utilization.
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better embodiment of this case is well understood to.
