In recent years, there is document to disclose some and utilizes the lever mechanics principle, will lift by crane the weight transmitting of thing self by certain mechanism and give mass, change the counterweight distance of mass, thereby realize the device of counterweight self-equalizing lifting cargo.
As Chinese patent application number: 200410043985.2, applicant: Wan Weirou, open day: on March 30th, 2005, publication number: CN1600669A, a kind of automatic weighing crane equipment is disclosed, its cardinal principle is to utilize the lever mechanics principle, the central part kinematic support that makes horizontal arm is on the hoisting crane column, arm lift heavy end sinks when lifting, the arm other end rises, draw high the mass that is positioned at the arm opposite side by steel rope along certain angle, play weight and mass lever balance, thereby realize lifting.
China Patent No.: ZL200510010544.7 and for example, patentee: Wan Weirou, Granted publication day: on July 9th, 2008, Granted publication number: CN100400409C, a kind of hydraulic automatic balanced crane installment is disclosed, its cardinal principle is also to be to utilize the lever mechanics principle, when the arm lifting, arm one end moves down, the pressure that arm is pressed down by the hydraulic gear that is installed on the hoisting crane column conducts to the mass that is positioned at the arm opposite side, mass is raised along certain angle, plays weight and mass lever balance, thereby realize lifting.
The disclosed two kinds of hoisting device of above-mentioned document have well been realized the counterweight self-equalizing, but have also been had certain deficiency, as complex structure, and the matching requirements height, the cost cost is more high.
The utility model content
The utility model is at the deficiencies in the prior art, purpose be to provide a kind of simple in structure, with low cost, operation is simple and easy, fuselage is light, can arbitrarily move place adaptable counterweight self-equalizing suspension transferring machine.
The utility model is achieved in that
A kind of counterweight self-equalizing suspension transferring machine is made up of base, column, arm and weight vehicle and equalizer bar, it is characterized in that horizontal mesh structure that base is welded into by steel and vertically triangular structure form, the below of base is provided with several cardan wheels; Column is vertically fixed on the suspension transferring machine base, and column and base junction can rotate freely by the flange that is provided with antifriction-bearing box, and a side roof part of column is equipped with the triangle arm, and the opposite side of column is provided with equalizer bar by the bottom; Equalizer bar is and is horizontally disposed with, and is made up of two parallel guide rail and a guide pipe, and equalizer bar one end is captiveed joint with the flange of base junction with column; Weight vehicle is made up of weight box and headstock, be placed on the equalizer bar guide rail, headstock is mounted with electrical motor, reductor, winch, and the wheel connecting shaft of weight vehicle is realized spacing the connection by the ring set of vertical links and connecting rod lower end with guide pipe, prevents that weight vehicle from wandering off on guide rail; Weight vehicle links to each other by some groups of tension springs with the end that equalizer bar is fixed in column by the wheel connecting shaft of headstock side-lower; Equalizer bar is provided with fixed pulley away from an end and the arm both upper ends thereof of column; Suspension hook is suspended under the arm by linking to each other with steel rope, and links to each other with the winch rope roll by above-mentioned fixed pulley.
The part that the utility model do not illustrate in detail all can adopt existing routine techniques to realize.
The utility model has the advantages that:
The utility model has utilized the stressed stretching and the automatically reset characteristic of tension spring cleverly, the deadweight that makes full use of engine installation simultaneously realizes less counterweight, realize counterweight balance preferably, saved the material that the overhead hoist base is used for counterweight, make the base miniaturization, the lighter province of suspension transferring machine material, simple in structure, the manufacturing cost of installation is low, and is easy and simple to handle.The cardan wheel of base makes suspension transferring machine to move easily simultaneously, and the place comformability strengthens greatly.In addition, utilize existing Electromechanical Control technology, can match safety controls such as limitation travel switch is installed, can well realize safe and reliable handling.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
With reference to accompanying drawing, the utility model is made up of base 1, column 2, arm 3, equalizer bar 4 and weight vehicle 5.Base 1 bottom is equipped with 4 cardan wheels 11.Column 2 and base 1 junction are provided with the flange 12 of built-in antifriction-bearing box, and 4 two guide rails 41 of equalizer bar and a guide pipe 42 are formed; Weight vehicle 5 is made up of weight box 51 and headstock 52, and headstock 52 is mounted with electrical motor, reductor, winch, and wheel 53 connecting shafts 54 of weight vehicle 5 are realized spacing the connection by the ring set 56 of vertical links 55 and connecting rod 55 lower ends with guide pipe 42; Weight vehicle 5 links to each other by 3 groups of tension springs 6 with the end that equalizer bar 4 is fixed in column by the wheel connecting shaft of headstock 52 side-lowers; Equalizer bar is provided with fixed pulley 7 away from an end and the arm both upper ends thereof of column; Suspension hook 9 is suspended from arm 3 times by linking to each other with steel rope 8, and links to each other with the winch rope roll by above-mentioned fixed pulley 7.
Working process of the present utility model is as follows:
When the suspension transferring machine lifting cargo, the gravity of goods 10 impels weight vehicle 5 to move toward column 2 far-ends on the guide rail 41 of equalizer bar 4 by the draw of steel rope 8, and passes through the position-limiting action of guide pipe 42, make weight vehicle 5 can not wander off on guide rail 41, tension spring 6 is stretched.According to the weight size of goods 10, can in weight box 51, suitably place the counterweight material.The power that is subjected to when spring 6 reaches balance when equating with the gravity of goods 10, and weight vehicle 5 stops to move, and the winch rope roll rotates, by steel rope 8, pulley 7, suspension hook 9 effect lifting cargos 10.Because the flange 12 between base 1 and the column 2 flexibly connects, and tries hard to recommend outside under the moving situation, arm 3 can freely rotate, and can easily the destination be arrived in lifting cargo 10 handlings.Under the effect of reductor, goods 10 can drop to the destination gently, and the spring 6 that does not hang thing 10 actions of gravity restores to the original state automatically, and weight vehicle 5 is return thereupon.Along with the increase of lifting cargo 10 weight, the pulling force that spring 6 is subjected to is big more, and weight vehicle 5 shifts out far away more, remains the balance of gravity and spring 6 pulling force, and suspension transferring machine is realized the balance trouble free service.
