Abstract

The utility model relates to a grab bucket stabilizer for a crane. The grab bucket stabilizer for the crane comprises a crane jib, a movable slider is mounted on a track which is welded to the bottom of the crane jib, a movable pulley is arranged at one end of the movable slider, and a third fixed pulley is fixed onto the crane jib at the other end of the movable slider. A first fixed pulley is fixed to the bottom of the crane jib through angle steel, a second fixed pulley is fixed to the end of the crane jib, and a steel wire rope sequentially bypasses the third fixed pulley, the movable pulley, the second fixed pulley and the first fixed pulley to be connected with a grab bucket. The grab bucket stabilizer for the crane is compact and reasonable in structure and convenient in installation, and the movable slider of a certain weight is designed on the crane jib and connected onto the grab bucket through the steel wire rope by the aid of a pulley block, so that the grab bucket in movement is always under the gravity action, grab bucket stabilization is realized, operation is simple and convenient for operators, operation efficiency is improved, and safety factor is increased.

Description

Grab bucket stabiliser for hoisting crane
Technical field
The utility model relates to weight-lifting equipment technical field, grab bucket stabiliser for especially a kind of hoisting crane.
Background technology
Grab bucket at harbour, shipping work uses extensively; grab bucket in use; due to and steel rope between belong to and flexibly connect; when hoisting crane moves; itself has inertia grab bucket, usually there will be grab bucket amplitude of fluctuation too large, makes operating personal not control grab bucket by actv.; reduce greatly the operating efficiency of hoisting crane, and have potential safety hazard.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, and grab bucket stabiliser for a kind of hoisting crane rational in infrastructure is provided, thereby according to the principle of weight stability maintenance, control grab bucket that can be stable, is used reliable and securely, and work efficiency is high.
The technical scheme that the utility model adopts is as follows:
A grab bucket stabiliser for hoisting crane, comprises arm, and the bottom welding of described arm has track, on described track, movable slider is installed, and the one end that is positioned at movable slider is provided with movable pulley, is fixed with the 3rd fixed pulley on the arm for the movable slider other end; The bottom of described arm is fixed with the first fixed pulley by angle steel, and the end that is positioned at arm is fixed with the second fixed pulley, and steel rope is walked around successively the 3rd fixed pulley, movable pulley the second fixed pulley, the first fixed pulley and grab bucket and is connected.
Further improvement as technique scheme:
The one end that is positioned at track is provided with shock absorber.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy for installation, by design the movable slider of constant weight on arm, by assembly pulley, with steel rope, be connected to grab bucket upper, grab bucket, in action, will have individual Action of Gravity Field in grab bucket always, thereby play the effect of stable grab bucket, operating personal is easy and simple to handle, has improved operating efficiency, has increased safety factor.
Accompanying drawing explanation
Fig. 1 is this practical structural representation.
Fig. 2 is the structural representation of the utility model movable slider.
Wherein: 1, shock absorber; 2, track; 3, arm; 4, movable slider; 5, movable pulley; 6, the first fixed pulley; 7, steel rope; 8, the second fixed pulley; 9, the 3rd fixed pulley.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, grab bucket stabiliser for the hoisting crane of the present embodiment, comprises arm 3, the bottom welding of arm 3 has track 2, movable slider 4 is installed on track 2, and the one end that is positioned at movable slider 4 is provided with movable pulley 5, is fixed with the 3rd fixed pulley 9 on the arm 3 for movable slider 4 other ends; The bottom of arm 3 is fixed with the first fixed pulley 6 by angle steel, and the end that is positioned at arm 3 is fixed with the second fixed pulley 8, and steel rope 7 is walked around successively the 3rd fixed pulley 9, movable pulley 5 second fixed pulleys 8, the first fixed pulley 6 and grab bucket and is connected.
The one end that is positioned at track 2 is provided with shock absorber 1.
In actual use procedure, grab bucket, when work, can reach stable grab bucket with movable slider 4 along with track 2 slides, and reduces the effect of inertia.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
