Description

The automatic weighing crane equipment
Technical field: the present invention relates to crane, hoisting crane, be specially a kind of automatic weighing crane equipment.
Background technology: at present, normally used weight-lifting equipment mainly is by the weight (as automobile) of self or fixed weight (as tower crane) guarantee the to sling object of constant weight, even if mobile counterweight is also arranged, the designed concept of adjusting travel, but mobile counterweight also wants outer power to realize.Annual throughout the country, every day is dead because tower crane collapses and people that injure is too many, with regard to Harbin City the first half of this year, two tower cranes collapse injures and deaths, death incident has just taken place.
Summary of the invention: the object of the present invention is to provide a kind of simple in structure, with low cost, safe and reliable, easy to use, mechanics principle of using lever, by the gravitation of the earth to object, realize the self-equalizing between hanging object and this machine counterweight, the automatic weighing crane equipment that uses other's strength to boost yourself.The object of the present invention is achieved like this: it comprises support (1), fuselage (2), arm (3) and weight vehicle four parts.Cylindrical bearing (5) top is connected with fuselage (2), the bottom is connected with support (1), the weight box (11) that has arm axle sleeve (17) to be connected on the weight box track (7) between fuselage (2) and the arm (3) is connected with steel rope (9), and the other end of steel rope (9) is connected and fixed through the bull wheel of diameter-changing wheel (10); One end of steel rope (9) is connected with the steamboat of diameter-changing wheel (10), and the other end is connected with wire line thimble (18); One end of steel rope (9) is connected with winch, two fixed pulleys (16) of the other end on arm (3) are connected with suspension hook (4); Weight box track (7) is 15 ° with horizontal angle α---20 °.Support (1) is to constitute rectangular base by I-beam section (22), I-beam section (22) diagonal line constitutes four equilateral triangles, I-beam section (22) connects and composes right-angled triangle with support central siphon (21), and support column (13) one ends are connected with support central siphon (21), the other end is connected with garden taper roller bearing (15).Arm (3) is formed several right-angled triangles by angle steel (23) and steel pipe (24), garden steel (25), is connected with a fixed pulley (16) between two angle steel (23).The bottom of weight box (11) has four road wheels (6) to be connected with weight box track (7) running-fit, and two weight box track (7) one ends are captiveed joint with fuselage (2), the other end connects and composes triangle through counter-balanced carriage support arm (14) and fuselage (2).The utility model has the advantages that: simple in structure, with low cost, safe and reliable, flexible operation, easy to use, use other's strength to boost yourself that art is good for strength.Set-up time is short, in light weight.Reduced dead, casualty rate, until to not having.
Description of drawings: Fig. 1 is a structural principle scheme drawing of the present invention; Fig. 2 looks scheme drawing for stand structure principle master of the present invention; Fig. 3 is a stand structure principle B-B cross-sectional schematic of the present invention; Fig. 4 looks scheme drawing for airframe structure principle master of the present invention; Fig. 5 is an airframe structure principle A-A cross-sectional schematic of the present invention; Fig. 6 is a boom structure principle schematic top plan view of the present invention; Fig. 7 looks scheme drawing for boom structure principle master of the present invention; Fig. 8 is a weight vehicle structural principle schematic top plan view of the present invention; Fig. 9 hangs the thing scheme drawing for structural principle high building of the present invention; Figure 10 is a structural principle of the present invention level land handling goods scheme drawing.19-cardan wheel, 12-travel switch, 20-lifting pawl, 26-object.
The specific embodiment: cylindrical bearing (5) top is connected with fuselage (2), the bottom is connected with support (1), there is arm axle sleeve (17) to be connected between fuselage (2) and the arm (3), weight box (11) on the counter-balanced carriage (7) is connected with steel rope (9), and the other end of steel rope (9) is connected and fixed through the bull wheel of diameter-changing wheel (10); One end of steel rope (9) is connected with the steamboat of diameter-changing wheel (10), and the other end is connected with wire line thimble (18); One end of steel rope (9) is connected with winch, two fixed pulleys (16) of the other end on arm (3) are connected with suspension hook (4); Weight box track (7) is 15 ° with horizontal angle α---20 °.Support (1) is to constitute rectangular base by I-beam section (22), I-beam section (22) diagonal line constitutes four equilateral triangles, I-beam section (22) connects and composes right-angled triangle with support central siphon (21), and support column (13) one ends are connected with support central siphon (21), the other end is connected with garden taper roller bearing (15).Arm (3) is formed several right-angled triangles by angle steel (23) and steel pipe (24), garden steel (25), is connected with a fixed pulley (16) between two angle steel (23).The bottom of weight box (11) has four road wheels (6) to be connected with weight box track (7) running-fit, and two weight box track (7) one ends are captiveed joint with fuselage (2), the other end connects and composes triangle through counter-balanced carriage support arm (14) and fuselage (2).Working process of the present invention:, spur steel rope, lift by crane object by fixed pulley when winch clockwise rotates.Because the hanging object own wt move downwards on the front end of arm, and lifts upward the rear end of arm, the pulling steel rope moves right along the weight box track by diameter-changing wheel pulling weight box.When hanging object weight in specialized range, weight box walk keep balance with suspended object certain a bit stop, suspended object is mentioned by winch.Rotate fuselage with hand, can 360 ° of rotations, the counter-rotation winch, object is put down, and under the effect on gravity slope, weight box returns to original position.When suspended object weight during greater than rated weight, weight box is walked to the travel switch place, promotes travel switch, the winch outage.Take down the part suspended object, when making the object total weight be equal to or less than rated weight, travel switch is connected, and winch restores electricity, normal operation.The utility model is that the weight and the object of object moves the required resistance that overcomes at natural downslide on the inclined-plane and object on the inclined-plane.The present invention and traditional hoisting crane comparison have improved work efficiency.With 0.5 ton hoisting crane is example, in the automobile handling goods, can save 10 labour powers, can save 20-50 labour power in the building ground.Safe and reliable.By this machine counterweight, winch the bottom of complete machine, the stability and the safety that have improved equipment greatly all have been designed into.
