Abstract
The invention relates to a crane grab bucket stabilizer. The stabilizer comprises a lifting arm, a track is welded on the bottom of the lifting arm, a moving slide block is arranged on the track, a moving pulley is arranged on one end of the moving slide block, a third fixed pulley is fixed on a lifting arm which is arranged on the other end of the moving slide block; a first fixed pulley is fixed on the bottom of the lifting arm through an angle iron, a second fixed pulley is fixed on the end part of the lifting arm, a steel wire rope orderly go through the third fixed pulley, the moving pulley, the second fixed pulley, and the first fixed pulley and finally is connected to the grab bucket. The crane grab bucket stabilizer has the advantages of compact and reasonable structure and convenient assembly. A moving slide block with a certain weight is arranged on the lifting arm, then the moving slide block is connected to the grab bucket by a pulley assemble through a steel wire rope; when the grab bucket moves, a gravity will be always applied on the grab bucket so as to have a stabilizing effect; an operator is convenient to operate the stabilizer, so that the operation efficiency is improved and the safety coefficient is increased.
Description
Technical field
The present invention 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.
Summary of the invention
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 solution adopted in the present invention 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.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, 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 movable slider of the present invention.
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 invention 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 explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
