Abstract
The utility model provides a traveling mechanism of a stacker reclaimer of a round stock yard, which comprises a traveling trolley and a round rail. Both a wheel tread surface of the traveling trolley and a rail surface contacting with the wheel tread surface are arranged obliquely, and an inner contact point of the wheel tread surface contacting with the rail surface is higher than an outer contact point of the wheel tread surface contacting with the rail surface. Since the wheel tread surface of the traveling trolley and the rail surface contacting with the wheel tread surface are arranged obliquely, the problem of sliding caused by the fact that the inner side and the outer side of the wheel tread surface are different in traveling distance and identical in rotation speed when the traveling trolley travels along the round rail is solved, sliding abrasion of the wheel tread surface and the rail surface is eliminated, and power consumption for traveling driving is reduced.

The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Fig. 5 is the sectional structure scheme drawing of the running mechanism (running mechanism in the utility model also can be referred to as traveling gear) of the utility model first embodiment, and Fig. 6 is the local A enlarged diagram of the running truck of running mechanism shown in Figure 5.Like Fig. 5 and shown in Figure 6; Circular stockyard stacker-reclaimer running mechanism comprises running truck 20 and circuit orbit 30; Wherein, The wheel tread 20a of running truck 20 and with the equal tilted configuration of orbital plane of the contacted circuit orbit 30 of this wheel tread 20a, form the conical surface respectively, and by the inboard contact point B of said wheel tread 20a and orbital plane 30a laterally contact point A tilt.
Below in conjunction with Fig. 5 and Fig. 6 the principle of work of the running mechanism of the utility model is described.
In the utility model, the wheel tread 20a of running truck 20 is a conical suface, and the outside diameter of wheel tread is greater than the inside diameter of wheel tread.Fig. 5 and shown in Figure 6 for another example, R is the distance of orbit centre line-spacing center of gyration; D is a running truck wheel tread centerline diameter; D1 is the diameter of running truck wheel tread and orbital plane outside contact point; D2 is the diameter of running truck wheel tread and the inboard contact point of orbital plane; B is the horizontal projection width of wheel tread and the inside and outside contact surface of orbital plane; A point and B point are respectively the outside and inboard contact point of wheel tread and orbital plane.
When running truck around center of gyration traveling one during week, at A point place, wheel distance travelled is that the theoretical revolution of 2 π (R+b/2), wheel is (2R+b)/D1; At B point place, wheel distance travelled is that the theoretical revolution of 2 π (R-b/2), wheel is (2R-b)/D2.For the theoretical revolution that makes A, 2 of B locate wheel equates that then needing wheel tread is taper, is D/2R through calculating tapering, i.e. the ratio of wheel center linear diameter and circuit orbit centerline diameter.
Suitable with wheel tread, the plane on the track also is taper, and tapering and wheel tread tapering are complementary.The running truck of this version is in the process of center of gyration operation; Wheel tread is identical with the theoretical revolution of the wheel at orbital plane inboard and outside contact point place; Make the whole tread of wheel can both be on orbital plane pure rolling; Thereby eliminated the slippage wearing and tearing of orbital plane and wheel tread, reduced the watt loss that traveling drives.
Preferably, the tapering of wheel tread 20a is D/2R.Certainly, because the diameter of circuit orbit is bigger, generally more than 5 meters; Little to the taper value influence, therefore the rough diameter of circuit orbit capable of using comes taper value, in addition; The vary in diameter amplitude of circuit orbit is little; For example, can adopt the wheel tread and the orbital plane of same taper value, on engineering, use with convenient less than 20% o'clock.
In addition, the diameter of wheel is relevant with taper value, after the taper value of the orbital plane of circuit orbit is selected, can select the wheels of different sizes, so that the tapering of the tapering of wheel tread and orbital plane is complementary, this is very significant on engineering.
Fig. 7 is the sectional structure chart of the running mechanism of the utility model second embodiment.As shown in Figure 7, the present embodiment and the first embodiment difference are that the outer ledge of wheel tread 20a is provided with wheel rim 20b.Inside edge at wheel tread does not have wheel rim, so makes things convenient for the machinework of wheel.
Fig. 8 is the sectional structure chart of the running mechanism of the utility model the 3rd embodiment.As shown in Figure 8, the present embodiment and the first embodiment difference are that the inside edge of wheel tread 20a is provided with wheel rim 20c.Outer ledge at wheel tread does not have wheel rim, so makes things convenient for the machinework of wheel.
Fig. 9 is the sectional structure chart of the running mechanism of the utility model the 4th embodiment.As shown in Figure 9, the present embodiment and the first embodiment difference are that the inside edge of wheel tread 20a and inside edge all are not provided with wheel rim, to make things convenient for the processing of wheel face.
The whole wheel tread of the running truck of the running mechanism of the utility model can be on orbital plane pure rolling, thereby eliminated the skimming wear of orbital plane and wheel tread, reduced the watt loss that traveling drives.Need to prove that the running mechanism of the utility model can be used for gantry type circular stockyard stacker-reclaimer, also can be used on the bridge circular stockyard stacker-reclaimer.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
