Abstract
A lorry-mounted crane final position self-lying hook belongs to a hook of an engineering mechanism. The two sides of an arm head protrusion sliding track of the self-lying hook are connected with an arm head left pulley and an arm head right pulley respectively; a hook assembly is connected at the lower end of a roller component; a hook left pulley and a hook right pulley are connected in the hook assembly; wire ropes are connected between the arm head left and right pulleys and the hook left and right pulleys; the arm head left pulley and the hook left pulley are arranged at an angle of 90 DEG, and the arm head right pulley and the hook right pulley are arranged at an angle of 90 DEG. The invention has the advantages that the hook assembly is driven to overturn automatically through wire rope hoist lift force; the hook is tightened horizontally on the lower plane of a suspension arm; the sight of a drive is not obstructed by the hook and cables, so as to improve running safety, prevent poor effect of a carriage deformation caused by fixing the wire rope too tight, can guarantee certain cargo height, maximize the cargo space and have no need for manual intervention during whole hook tightening and loosening processes.
Description
Technical field
The present invention relates to a kind of suspension hook of engineering mechanism, particularly a kind of end location self-lying lift hook of lorry-mounted crane.
Background technology
At present, general lorry-mounted crane, suspension hook must be fixed with steel rope or with sleeper in the process of moving.Therefore the operator is when lorry-mounted crane begins or finishes operation, and cargo platform goes to become flexible or fixing suspension hook about all wanting, and this has not only strengthened working strength, inconvenient operation, has also increased the operation safety hazard; Simultaneously,, limited cargo height, be unfavorable for lade because suspension hook will take certain loading height space; When crane arm is fixed on the operator's compartment top, in driving process, disturb pilot's line of vision to bring hidden danger to traffic safety.
Summary of the invention
The objective of the invention is to provide a kind of: be convenient to operation, help lade, do not disturb the end location self-lying lift hook of lorry-mounted crane of pilot's line of vision.
The object of the present invention is achieved like this: this self-lying lift hook includes arm head left side pulley (3), arm head right side pulley (4), arm head projection slide rail (5), steel rope (6), roll wheel assembly (7), suspension hook assembly (8), suspension hook left side pulley (10), suspension hook right side pulley (14), be connected with arm head left side pulley (3) and arm head right side pulley (10) respectively in the both sides of arm head projection slide rail (5), be connected with suspension hook assembly (8) in roll wheel assembly (7) lower end, in the suspension hook assembly, be connected with suspension hook left side pulley (10) and suspension hook right side pulley (14), be connected with steel rope (6) between arm head left side pulley (3) and arm head right side pulley (4) and suspension hook left side pulley (10) and suspension hook right side pulley (14), arm head left side pulley (3) and arm head right side pulley (4) are 90 degree with suspension hook left side pulley (10) and suspension hook right side pulley (14) and arrange.
Beneficial effect: owing to adopted such scheme, two pulleys of arm head and two pulleys of suspension hook are mutually 90 degree states.After hoist rope is walked around from arm arm head left side pulley 3, from roll wheel assembly 7 left side processes, walk around behind the suspension hook right side pulley 14 through arm head right side pulley 4, the process once more from roll wheel assembly 7 right sides is walked around suspension hook left side pulley 10 and is fixed on arm head assembly 2 one sides; Owing to adopted two rollers, and the winding form of steel rope, guaranteed the stabilized conditions of (embedding) when suspension hook roll wheel assembly 7 contacts with the protruding slide rail 5 of arm head; Be convenient to operation, help lade, do not disturb pilot's line of vision, reached purpose of the present invention.
Advantage: play lift drive suspension hook assembly by steel rope and overturn automatically, the suspension hook level is tightened up on the lower plane of arm, when crane arm turns to the operator's compartment upper fixed to exercise, suspension hook and rope can not hinder driver vision, the profit that can also reduce steel rope when exercising in the rainy day is splashed to the on glass of operator's compartment front, has improved the safety of travelling; Also can prevent in the past fixedly tension of steel rope, cause the harmful effect of vehicle frame distortion; When if crane arm turns to the container upper fixed to exercise, can guarantee certain loading height, increase cargo space to the full extent, and whole suspension hook tightens up the process of loosening and does not need manual intervention.

The specific embodiment
Embodiment 1: embodiment 1: this self-lying lift hook includes arm head left side pulley 3, arm head right side pulley 4, arm head projection slide rail 5, steel rope 6, roll wheel assembly 7, suspension hook assembly 8, suspension hook left side pulley 10, suspension hook right side pulley 14, both sides at arm head projection slide rail 5 are connected with arm head left side pulley 3 and arm head right side pulley 10 respectively, be connected with suspension hook assembly 8 in roll wheel assembly 7 lower ends, in the suspension hook assembly, be connected with suspension hook left side pulley 10 and suspension hook right side pulley 14, be connected with steel rope 6 between arm head left side pulley 3 and arm head right side pulley 4 and suspension hook left side pulley 10 and suspension hook right side pulley 14, arm head left side pulley 3 and arm head right side pulley 4 are 90 degree with suspension hook left side pulley 10 and suspension hook right side pulley 14 and arrange.
In Fig. 2, principle of work: under the prerequisite that does not influence the force analysis result,, simplify 7, two rollers of roll wheel assembly and be reduced to a roller for ease of carrying out force analysis.Obtain by force analysis, hoist rope promotes suspension hook, when the roller of suspension hook contacts with the arm head projection slide rail 5 of arm head (contact wire is A), because of left side steel rope pair roller shows the F that exerts oneself at first, it is the effect that roller is subjected to left side power F, because the arm of force is S1, so steel rope pair roller center, left side produces moment M1=F * S1, cause roller to be subjected to arm head projection slide rail 5 pair rollers friction force f to the right at contact wire A, because the friction force f pair roller center arm of force is S2, produce moment M2=f * S2 simultaneously, cause roller to roll, clockwise rotate along arm head projection slide rail 5 so drive whole suspension hook.
