Abstract

A material stacking-reclaiming machine with bucket wheel and front arm pulled at more points is composed of front arm, hanger, vertical pillar, fixed pulley, steel cable, and counter weight. The one end of steel cable is linked to hanger and its another end is acted by counterweight, so the middle of from arm is pulled upward. As a result, the cross-section of front arm may be smaller.

Description

Front arm frame multi point tensional bucket wheel loader

The present invention relates to harbour, harbour, steel mill and be used to load and unload the bucket-wheel stacker reclaimer of material.

Existing bucket-wheel stacker reclaimer, far away from the bucket-wheel stacker reclaimer track because of the material of being got by heap, preceding jib is done longlyer, and in order to reach the performance requriements of each side, each size correspondence of preceding jib transversal surface is also done more greatly.Therefore, preceding jib is just heavier, and the rear portion counterweight on the equalizing bar is also heavy, and each supporting of bottom and each part size of crawler body and the intensity of being born are bigger, and its weight also is increased, so the machine gross weight is bigger.

Purpose of the present invention just provides a kind of front arm frame multi point tensional bucket wheel loader, makes it each size of transversal surface by preceding jib Multiple Wounds and reduces, and reduces exchange weight, the purpose of cost-cutting thereby reach.

In order to reach above purpose, principle of the present invention is: in preceding jib, except an existing stay cord, at stay cord and the preceding jib place of linking to changeing between the mandrel, there are many places to be held, after steel cable is walked around the fixed pulley that is positioned on the column, are subjected to counterweight and give its pulling force by steel cable.According to above principle, its technical scheme is: be equipped with suspension member on preceding jib, fixed pulley is arranged on column, steel cable one end is positioned on the suspension member, and the other end is equipped with counterweight, passes through fixed pulley in the middle of the steel cable; In addition, longer because of preceding jib, after column rotated, its front steel cable was flexible longer, its counterweight might be collided with other following parts, therefore, adopts steel cable one end to be positioned on the suspension member, the other end is positioned on the column, and the fixed pulley that is positioned on column is walked around in the centre, also walks around movable pulley; Be equipped with hook on the movable pulley, counterweight is housed on the hook.

After adopting this structure, many places, preceding jib middle part are stressed, each size decreases of its transversal surface, and exchange weight saving, cost reduces.

The invention will be further described below by drawings and Examples.

Accompanying drawing 1 is first embodiment accompanying drawing of bucket-wheel stacker reclaimer of jib before the multiple spot tension of the present invention.

As shown in Figure 1, be equipped with suspension member 2 on preceding jib 1, fixed pulley 4 is arranged on column 3, steel cable 5 one ends are positioned on the suspension member 2, and the other end is equipped with counterweight 6, and steel cable 5 centre portions are by fixed pulley 4; Another steel cable 5 one ends are positioned on the suspension member 2, and the other end is positioned on the column 3, and are middle by being positioned on the fixed pulley 4 on the column 3, also by movable pulley 7, hook 8 are housed on the movable pulley 7, are equipped with counterweight 6 on the hook 8.Before stay cord 9 draws during jib 1, preceding jib 1 mandrel 10 that rotates rotates, and counterweight 6 moves downward; When stay cord 9 loosens, preceding jib 1 is downwards the time, and preceding jib 1 mandrel 10 that rotates rotates counterweight 6 upward movements.

The present invention is divided by outside the last scheme, also can adopt all counterweights 6 all directly and steel cable 5 form that directly links; Also can adopt all counterweights 6 to be positioned on the hook 8, hook 8 forms that are contained on the movable pulley 7; Suspension member 2 also can be integrated with column 3; Above scheme all is a content of the present invention.

Claims (1)

1. a front arm frame multi point tensional bucket wheel loader is by preceding jib, changeing mandrel, stay cord, column and equalizing bar forms, it is characterized in that: on preceding jib 1, be equipped with suspension member 2, fixed pulley 4 is arranged on column 3, steel cable 5 one ends are positioned on the suspension member 2, the other end is equipped with counterweight 6, passes through fixed pulley 4 in the middle of the steel cable 5; Another part steel cable 5, one ends are positioned on the suspension member 2, and the other end is positioned on the column 3, and are middle by fixed pulley 4, also by movable pulley 7, hook 8 are housed on the movable pulley 7, are equipped with counterweight 6 on the hook 8.
