Abstract
The utility model relates to an end self-lying lift hook, which is used on the hoisting machinery for the automobile. The end self-lying lift hook comprises a fixed pulley block, a movable pulley block, a steel rope and a lift hook. The fixed pulley block is connected with a boom; the movable pulley block is connected with the fixed pulley block through the steel rope (3); the lower end of the movable pulley block is connected with the lift hook (9); and the fixed pulley block and the movable pulley block are arranged to form a 90-degree angle. The steel rope is lifted from the head of the boom, passes around the left pulley, by the left side of the roller component, around the right pulley of the lift hook, by the right pulley of the head of the boom, by the right side of the roller component again, and around the left pulley of the lift hook, and is then fixed at one side of the head of the beam. Because of the two rollers and the winding way of the steel rope, the end self-lying lift hook ensures the stable contact between the roller component of the lift hook and the convex slide rail at the head of the beam. The utility model has the following advantages: the operation is convenient; the labor intensity is greatly reduced; the loading space in the height direction can not be occupied after the lift hook is collected, so the loading; and the sight of the driver can not be interfered during the driving process, thereby greatly improving the driving safety.
Description
Technical field
The utility model relates to the suspension hook that uses on a kind of car hosit tool, particularly a kind of final position self-lying lift hook.
Background technology
General car hosit or lorry-mounted crane all use suspension hook, and this car hosit tool suspension hook in the process of moving must be fixed with steel rope or with sleeper.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.
The utility model content
The purpose of this utility model is to provide a kind of: convenient working, help lade, do not disturb the final position self-lying lift hook of pilot's line of vision.
The purpose of this utility model is achieved in that this self-lying lift hook includes fixed pulley group, running block, steel rope and suspension hook, the fixed pulley group is connected with arm, running block leads to steel rope (3) and is connected with the fixed pulley group, be connected with suspension hook (9) in the running block lower end, fixed pulley group and running block are 90 degree and arrange.
Described fixed pulley group includes arm head right side pulley (1), arm head projection slide rail (2) and arm head left side pulley (8), pulley (8) and arm head right side pulley (1) on the left of two sides of arm head projection slide rail (2) are connected with arm head respectively.
Described running block includes roller assembly (4), suspension hook frame (5), suspension hook right side pulley (6), suspension hook left side pulley (7), be connected with suspension hook frame (5) in roller assembly (4) lower end, in the suspension hook frame, be connected with suspension hook right side pulley and suspension hook left side pulley (7), be connected with suspension hook in the bottom of suspension hook frame.
Beneficial effect: owing to adopted such scheme, 2 pulleys of arm head and 2 pulleys of suspension hook are mutually 90 degree states.After hoist rope is walked around from arm arm head left side pulley, from roller assembly left side process, walk around behind the pulley of suspension hook right side through arm head right side pulley, the process once more from the roller assembly right side is walked around suspension hook left side pulley and is fixed on arm head one side; Because adopted two roller bearings, and the winding form of steel rope, the stabilized conditions when the suspension hook roller assembly contacts with arm head projection slide rail guaranteed; Be convenient to operation, help lade, do not disturb pilot's line of vision, reached the purpose of this utility model.Advantage: when hoisting crane begins or finish operation, up and down cargo platform does not go loosening or fixing suspension hook, operation is convenient, greatly reduce working strength, suspension hook does not take the loading height space after drawing in, help lade, in driving process, do not disturb pilot's line of vision, improved traffic safety greatly.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is stressed principle analysis figure of the present utility model.
The specific embodiment
Embodiment 1: this self-lying lift hook includes fixed pulley group, running block, steel rope and suspension hook, the fixed pulley group is connected with arm, the logical steel rope 3 of running block is connected with the fixed pulley group, is connected with suspension hook 9 in the running block lower end, and fixed pulley group and running block are 90 degree and arrange.
Described fixed pulley group includes arm head right side pulley 1, arm head projection slide rail 2 and arm head left side pulley 8, is connected with arm head left side pulley 8 and arm head right side pulley 1 respectively in two sides of arm head projection slide rail 2.
Described running block includes roller assembly 4, suspension hook frame 5, suspension hook right side pulley 6, suspension hook left side pulley 7, be connected with suspension hook frame 5 in roller assembly 4 lower ends, in the suspension hook frame, be connected with suspension hook right side pulley and suspension hook left side pulley 7, be connected with suspension hook in the bottom of suspension hook frame.
In Fig. 2, principle of work: under the prerequisite that does not influence the force analysis result, for ease of carrying out force analysis, we simplify roller assembly No. 4, and two roller bearings are reduced to a roller bearing.Obtain by force analysis, hoist rope promotes suspension hook, when suspension hook 4 roller assemblies contact with arm head 2 arm heads projection slide rail (contact wire is A), because of the left side steel rope shows the F that exerts oneself at first to roller bearing, it is the effect that roller bearing is subjected to left side power F, because the arm of force is S1, so the left side steel rope produces moment M1=F * S1 to the roller bearing center, cause roller bearing to be subjected to 2 arm heads projection slide rail to roller bearing 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 bearing to roll, clockwise rotate along 2 arm heads projection slide rail so drive whole suspension hook.
