Description
Technical field
The utility model relates to a kind of swing type mechanism for tower machine, belongs to tower machine field of engineering technology.
Background technology
The gyroscopic movement of tower machine, substantially be all that employing electrical motor is power, pass through retarder, the gyroscopic movement that engages to realize topside of miniature gears and bull gear, bull gear is fixed on bottom section, and miniature gears is fixed in topside, after the power of electrical motor is delivered on pinion shaft by retarder, miniature gears will move in a circle along bull gear, thereby realizes the gyroscopic movement of topside.In Large Towers machine, this traditional driving system cost is very high, and speed is a definite value.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and the hydraulic-driven swing type mechanism that a kind of cost is low, can realize rotating speed control is provided.
For solving this technical matters, the utility model provides a kind of hydraulic-driven swing type mechanism for tower machine, be arranged between the bottom section and topside of tower machine, comprise three oil cylinders, hinge and upper bearing, described upper bearing is fixed in the topside of tower machine, upper bearing eccentric setting has hinge, one end of described three oil cylinders is hinged on this bias hinge jointly, the other end is hinged on respectively on the bottom section of tower machine, being fixedly hinged of described each oil cylinder is not a little 0 ° or 180 ° with the line of hinge center of gyration, the dead point that is each oil cylinder can not occur simultaneously.
On the bottom section of tower machine, be provided with fixed-hinged support, described oil cylinder is connected with the bottom section of tower machine by fixed-hinged support.
Beneficial effect: the utility model adopts hydraulic ram drive system can carry out capacity adjustment to control thrust and speed, obtaining more easily of mechanical movement change controlled, and can on Large Towers machine, realize rotating speed control and thrust control, stable action, to impact little, speed governing convenient, especially cost is low, has promotional value.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: bearing, 4 fixed-hinged supports on 1 oil cylinder, 2 hinges, 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model is arranged between the bottom section and topside of tower machine, comprises oil cylinder 1, hinge 2 and upper bearing 3.
The utility model arranges three oil cylinders 1 altogether, one end of each oil cylinder 1 is hinged on respectively in the lower mechanisms of tower machine, bottom section is fixed, the other end is hinged on the hinge 2 in bearing 3, described hinge 2 is eccentrically set in bearing 3, and described upper bearing 3 is fixed in the topside of tower machine, belongs to a part for topside, belong to rotatable part, upper bearing 3 can drive revolving upper structure.
On the bottom section of tower machine, be provided with fixed-hinged support 4, described oil cylinder 1 is connected with the bottom section of tower machine by fixed-hinged support 4.
Being fixedly hinged of described each oil cylinder 1 is not a little 0 ° or 180 ° with the line of hinge 2 center of gyrations, and the dead point of each oil cylinder can not occur simultaneously.
Preferably, all center of gyrations only of the line of the fixed-hinged support 4 of any two oil cylinders 1.
The principle of work of this device is to change the flexible straight-line motion of oil cylinder 1 into topside rotatablely move.Because hinge 2 is eccentric settings, therefore thereby the thrust of oil cylinder 1 can produce a moment of torsion promotion hinge 2 to center of gyration hinge 2 to move in a circle, and hinge 2 rigidly connects in upper bearing 3, therefore hinge 2 drives upper bearing 3 and topside to do gyroscopic movement.Hinge 2 and revolving upper structure one week, each oil cylinder 1 can have two dead points, and reversing the arm of force is zero, and at this moment oil cylinder 1 is in high-low limit position.But because the fixed-hinged support 4 of each oil cylinder 1 is not 0 degree or 180 degree with the line of center of gyration hinge 2, the dead point of each oil cylinder 1 can not occur simultaneously.In the time that dead point appears in an oil cylinder 1, two other oil cylinder is not dead point, and driving torque still can be provided, and by three oil cylinders 1 in order flexible push-and-pull campaign continuously, can realize bearing 3 and topside and do continuous gyroscopic movement like this.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection domain of the present utility model.
The utility model adopts hydraulic ram drive system can carry out capacity adjustment to control thrust and speed, obtaining more easily of mechanical movement change controlled, and can on Large Towers machine, realize rotating speed control and thrust control, stable action, to impact little, speed governing convenient, especially cost is low, has promotional value.
