Description
Technical field
The utility model relates to tower crane.
Background technology
Tower crane is called for short the tower machine, also claims tower crane.At present, the tower machine is divided into turret machine and capstan head machine two big classes next time.What we were seen in many camp sites is exactly top slewing tower machine.The technology relevant with the application is top slewing tower machine.
Existing swinging tower machine mainly is made up of parts such as crane arm, body of the tower, rotary table, pinnacle of a pagoda (tower cap), luffing mechanism, lifting mechanism, swing type mechanism, counterbalanceds weight.Supernumerary segment connects height during for the ease of installation, and major part also all is provided with hydraulic lifting mechanism, is called top slewing jacking supernumerary segment and connects high tower machine.Wherein, the crane arm structural style is the carriage amplitude varying horizontal arm support, and the carriage amplitude varying jib mostly adopts the cross section truss of equilateral triangle; Body of the tower is the main body of tower machine structure, all adopts the truss standard knot connecting mode of square cross-section; The function of pinnacle of a pagoda is to bear the upper load that jib stay cord and equilibrium arm stay cord transmit, and passes to the body of the tower structure by structure members such as rotary tables; Counterbalanced weight is in order to constituting the balancing torque opposite with the hoisting moment direction, counterbalanced weight can be cylinder iron or ferro-concrete make.
The rotary table of swinging tower machine is to be made of last turntable, revolution support and following turntable; Swing type mechanism is made up of double-speed motor, hydraulic coupler, magnet stopper, reductor, miniature gears and bearing; Last turntable top is connected with the pinnacle of a pagoda, the inner ring that the bottom is supported with high strength bolt and revolution is fastening, the place ahead is connected with the crane arm root with bearing pin, the rear is connected with the equilibrium arm root with bearing pin, swing type mechanism is equipped with on the right side, the swing type mechanism miniature gears meshes with the big gear wheel that revolution is supported, and revolution is supported and fixed on the undersetting; Can make on the tower machine turntable drive crane arm when swing type mechanism moves turns round along the body of the tower axle center; The bottom that revolution is supported is turntable down, and the external toothing that revolution is supported is connected with high strength bolt with play turntable, and tower machine top load is passed to down turntable by turning round support, and the following and body of the tower standard knot of following turntable is connected; The swing type mechanism miniature gears is dragged by double-speed motor.
Because the said structure of rotary table, the deficiency of the existing swinging tower machine that brings is, 1, the big gear wheel that supports owing to revolution is fixed on the undersetting, when swing type mechanism moves, motor promptly turns round along the body of the tower axle center, only operate along direction when crane operator and to rotate and when not turning round the corresponding number of turns, the cable twisted shape that just congeals into causes cable bad early or causes electrical hazard; 2, because the structure of rotary table is limit, can not bear very big moment of flexure, so crane arm can not promote excessive load, in case mechanical accident takes place the overweight unstable phenomenon that causes easily.
Summary of the invention
The purpose of this utility model is to overcome existing unsafe technological deficiency, designs a kind of center shaft revolution diagonal-bracing type tower machine.
For reaching the above-mentioned purpose that has, the technical scheme that the utility model is taked is:
A kind of center shaft revolution diagonal-bracing type tower machine, it comprises tower seat, body of the tower, rotary table, pinnacle of a pagoda, crane arm, counterbalanced weight, luffing mechanism, lifting mechanism and swing type mechanism, it is characterized in that rotary table is made up of last turntable, center shaft, bracing frame and revolution big gear wheel; Bracing frame is to be formed by connecting by four corner posts and upper and lower stay bearing plate, upper and lower thrust baring is installed respectively on the upper and lower stay bearing plate, center shaft is installed on the bracing frame by upper and lower thrust baring, upper backup pad is fixed on the end face of center shaft, the pinnacle of a pagoda of tower machine is fixed on the turntable, and the revolution big gear wheel is fixed on the center shaft; Described swing type mechanism is fixed on bracing frame one side, and the miniature gears of swing type mechanism and revolution big gear wheel engagement drive center shaft and rotate, thereby realize the revolution of pinnacle of a pagoda when the electric motor starting of swing type mechanism;
In order to improve the load of tower machine, the utility model also comprises diagonal brace mechanism; Diagonal brace mechanism establishes a circle guide groove on a certain plane on body of the tower top, the revolution steel ring is installed in the guide groove, and the revolution steel ring is provided with diagonal brace, and the top of diagonal brace is connected on the crane arm; Rotate flexibly in order to turn round steel ring, be equipped with transfer roller on three faces that the revolution steel ring contacts with guide groove.
Good effect of the present utility model is: 1, because swing type mechanism is to be fixed on the rotary table bracing frame, motor is no longer along body of the tower axle center revolution, and no matter how the turning motor cable still maintains the original state in the pinnacle of a pagoda, can not cause cable bad or cause electrical hazard; 2, owing to increased diagonal brace mechanism, can bear very big moment of flexure,, be not easy to cause unstable phenomenon, avoid taking place mechanical accident so crane arm can promote excessive load.
