With the combination of the narrow tread and the wide tread, the narrow tread is used for guaranteeing a small power supply system, a limit system and the like are not affected by the change of the gauge of the trolley, and the wide tread can effectively eliminate the changes of the rail gauge and the wheel gauge, so that the trolley does not bite the rails; and the wheel gauge adjusting device can effectively adjust the wheel gauge of the trolley to keep the wheel gauge and the rail gauge same so as to prevent biting rail.
Description
Technical field
The utility model relates to the carriage walking field of mechanisms, in particular, relates to a kind of preventing gnawing rail carriage walking mechanism.
Background technology
The rail of gnawing of gauntry crane carriage walking mechanism almost is the chronic disease that all gauntrys crane all have, and gnaws rail and causes wearing and tearing for track, wheel, has a strong impact on its service life.Because the trolley track of gauntry crane is arranged on the girder, can produce distortion under the effect that girder carries outside, thereby cause the variation of track gauge.Here mainly contained in outer year: wind load, inertia loading, temperature difference expansion at sunshine load etc.; Simultaneously the gauntry crane dolly self can deform hanging the effect of carrying, thereby causes the variation of wheel gauge.The variation of track gauge and wheel gauge has fundamentally caused the rail of gnawing of dolly.Cause the reason of gnawing rail numerous, overcome a difficulty, mostly can't fundamentally solve, can only take the measure that delays,, but, certain potential safety hazard is arranged owing to put the oil and to influence its wind resistance such as coating lubricating oil in orbit.
According to above requirement, mechanism overcomes the existing in prior technology problem with regard to a kind of later-model preventing gnawing rail carriage walking of needs.
Summary of the invention
The utility model aims to provide a kind of preventing gnawing rail carriage walking mechanism.
According to an embodiment of the present utility model, a kind of preventing gnawing rail carriage walking mechanism is proposed, comprising:
Narrow tread wheel, the wheel of carriage walking mechanism first side are narrow tread wheel, and the width of narrow tread wheel is the 115%-125% of track width; Wide tread wheel, the wheel of carriage walking mechanism second side is wide tread wheel, the width of wide tread wheel is greater than the width of narrow tread wheel.
In one embodiment, preventing gnawing rail carriage walking mechanism comprises wheel gauge control apparatus, is connected to narrow tread wheel and wide tread wheel, regulates the spacing between narrow tread wheel and the wide tread wheel.
The electric power system of the dolly of preventing gnawing rail carriage walking mechanism is installed in narrow tread wheel one side in one embodiment.
In one embodiment, the caging system of preventing gnawing rail carriage walking mechanism dolly is installed in narrow tread wheel one side.
In one embodiment, the width of wide tread wheel is to obtain according to wind load, inertia loading, temperature difference expansion at sunshine LOAD FOR.Such as, the width of wide tread wheel is the 180%-200% of track width.
In one embodiment, the width of narrow tread wheel is 120% of a track width; The width of wide tread wheel is 190% of a track width.
Preventing gnawing rail carriage walking of the present utility model mechanism has following advantage:
1) mode that combines of narrow tread and wide tread, narrow tread is used to guarantee little electric power system, and because the variation of trolley span is affected, wide tread can not eliminated the variation of track, wheel gauge to caging systems etc. effectively, and that realizes dolly does not gnaw rail.
2) adopt convenient and reliable trolley span control apparatus; Can wheel gauge and track gauge be consistent by adjusting dolly wheel gauge, avoid gnawing rail.
Description of drawings
The above and other features of the present invention, character and advantage will become more obvious by the description below in conjunction with drawings and Examples, in the accompanying drawings, identical Reference numeral is represented identical feature all the time, wherein:
Fig. 1 a and Fig. 1 b have disclosed the constructional drawing according to the preventing gnawing rail carriage walking mechanism of one embodiment of the invention.
The specific embodiment
With reference to figure 1a and Fig. 1 b, the utility model proposes a kind of preventing gnawing rail carriage walking mechanism and solve problems of the prior art.Shown in Fig. 1 a and Fig. 1 b, this preventing gnawing rail carriage walking mechanism 100 comprises narrow tread wheel 102, wide tread wheel 104 and wheel gauge control apparatus 106.
The wheel of carriage walking mechanism 100 first sides is narrow tread wheel 102, and the width of narrow tread wheel 102 is the 115%-125% of track width.In one embodiment, the width of narrow tread wheel 102 is 120% of a track width.The span of the width of narrow tread wheel 102 rule of thumb is worth and obtains.
The wheel of carriage walking mechanism 100 second sides is wide tread wheel 104, and the width of wide tread wheel 104 is greater than the width of narrow tread wheel 102.The width of wide tread wheel 104 is to obtain according to wind load, inertia loading, temperature difference expansion at sunshine LOAD FOR.Such as, the width of wide tread wheel is the 180%-200% of track width.In one embodiment, the width of wide tread wheel 104 is 190% of a track width.The span of the width of wide tread wheel 104 be not rule of thumb value obtain, but one by amount that various load determined, according to the result of a measurement of wind load, inertia loading, temperature difference expansion at sunshine load, can calculate the width data of wide tread wheel 104.
Wheel gauge control apparatus 106 is connected to narrow tread wheel 102 and wide tread wheel 104, is used to regulate the spacing between narrow tread wheel 102 and the wide tread wheel 104.In long-term use, be that girder or dolly all can produce expendable plastic deformation, this distortion must be eliminated by other modes, wheel gauge control apparatus 106 also is provided for this reason in one embodiment, adjust dolly wheel gauge by wheel gauge control apparatus 106, wheel gauge and track gauge are consistent, avoid gnawing rail.
In one embodiment, the electric power system of dolly is installed in a side of narrow tread wheel 102, and the caging system of dolly also is installed in narrow tread wheel 102 1 sides.Narrow tread wheel 102 can guarantee little electric power system, and caging system is not because the variation of trolley span is affected.
Preventing gnawing rail carriage walking mechanism's assurance wheel gauge of the present utility model and track gauge are complementary, when distortion of dolly stand under load or the variation of main beam deformation generation gauge, narrow tread wheel and track sideshake are limited, guarantee that dolly electric power system, caging system etc. are not affected because gauge changes.Wide tread wheel and the enough sideshakes of interorbital, this gap can the compensation trolley gauges and the difference of track gauge, do not gnaw rail when guaranteeing carriage walking.
Preventing gnawing rail carriage walking of the present utility model mechanism possesses following advantage:
1) mode that combines of narrow tread and wide tread, narrow tread is used to guarantee little electric power system, and because the variation of trolley span is affected, wide tread can not eliminated the variation of track, wheel gauge to caging systems etc. effectively, and that realizes dolly does not gnaw rail.
2) adopt convenient and reliable trolley span control apparatus; Can wheel gauge and track gauge be consistent by adjusting dolly wheel gauge, avoid gnawing rail.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present invention; those skilled in the art can be under the situation that does not break away from invention thought of the present invention; the foregoing description is made various modifications or variation; thereby protection scope of the present invention do not limit by the foregoing description, and should be the maximum range that meets the inventive features that claims mention.
