Utility model content
For the deficiency under prior art, the utility model provides a kind of brake gear of cart for travelling up or down stairs.
To achieve these goals, the utility model solves the technical scheme that its technical matters adopts: a kind of brake gear of cart for travelling up or down stairs, comprise vehicle frame, the both sides, one end of vehicle frame are provided with BOGEY WHEEL, BOGEY WHEEL rotates and is arranged on BOGEY WHEEL erecting frame, one side of BOGEY WHEEL is provided with ring gear, be positioned on BOGEY WHEEL erecting frame that BOGEY WHEEL is provided with ring gear one side and be provided with slide rail, slide rail slidably connects slide bar, slide bar is fixed with the fixture block or bayonet lock that fasten with ring gear, the descending slip locations in bottom of described slide bar at least will exceed the outer rim of BOGEY WHEEL.
Further, described ring gear is ratchet ring gear.
Further, slide rail is parallel to the length direction of vehicle frame, and is slidably socketed the slide bar on slide rail and slides along the length direction of vehicle frame.
Further, the bottom of described slide bar is connected with roller.
The beneficial effects of the utility model: the brake gear of a kind of cart for travelling up or down stairs of the present utility model utilizes diff-H and the terrestrial attraction of step, the unsettled rear downslide of the roller of slide bar bottom is made to make fixture block block ratchet ring gear on BOGEY WHEEL, stop BOGEY WHEEL and retreat the one-level step falling down place, when the roller of slide bar bottom and step surface or earth surface, slide block moving is that fixture block throws off ratchet ring gear, freely rotate before and after BOGEY WHEEL, structure is simple, practical, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
Detailed description of the invention
The brake gear of a kind of cart for travelling up or down stairs as shown in Figure 1, comprise vehicle frame 1, the both sides, one end of vehicle frame 1 are provided with BOGEY WHEEL 2, BOGEY WHEEL 2 rotates and is arranged on BOGEY WHEEL erecting frame 3, one side of BOGEY WHEEL 2 is provided with ring gear 4, be positioned on BOGEY WHEEL erecting frame 3 that BOGEY WHEEL is provided with ring gear 4 one side and be provided with slide rail 5, slide rail 5 slidably connects slide bar 6, slide bar 6 is fixed with the fixture block 7 or bayonet lock that fasten with ring gear 4, the descending slip locations in bottom of described slide bar 6 at least will exceed the outer rim of BOGEY WHEEL 2.
Preferably, described ring gear 4 is ratchet ring gear, and ratchet ring gear is fixed on two BOGEY WHEEL 2 sides in opposite directions by screw or solder joint, and the diameter of ratchet ring gear is 2/3 of BOGEY WHEEL 2 diameter.
Preferably, slide rail 5 is parallel to the length direction of vehicle frame 1, and be slidably socketed the slide bar 6 on slide rail 5 and slide along the length direction of vehicle frame 1, slide rail 5 is fastenedly connected with BOGEY WHEEL erecting frame 3, and (preferably adopt and weld) is integral, and slide bar 6 is slided with slide rail 5 by the chute offered along its length and is connected.
Preferably, the bottom of described slide bar 6 is connected with roller 8, and roller 8 is rotatably connected on the sidewall of slide bar 6 bottom by bearing pin, and the diameter of roller 8 is 1/10 of hook tooth ring diameter.
Control method of the present utility model and braking procedure, when cart for travelling up or down stairs climbing runs, vehicle frame 1 keeps the angle of inclination (angle be generally 40 ° to 45 °) certain with horizontal mask, when cart for travelling up or down stairs drags on level land, roller 8 and earth surface, it is disengaged position that fixture block 7 on slide bar 6 or bayonet lock keep with ratchet ring gear, BOGEY WHEEL 2 twocouese rolls unrestricted, when cart for travelling up or down stairs speeling stairway, vehicle body is raised and is made BOGEY WHEEL 2 going up one level step by climbing mechanism, in the process that vehicle frame rises, slide bar 6 slides to down extreme lower position rear roller 8 gradually and leaves step surface (now fixture block 7 or bayonet lock glide with slide bar 6 and block ratchet ring gear, BOGEY WHEEL can only one direction rolls forward, cannot retreat, when BOGEY WHEEL falls within just soaring step edge, roller 8 is suspended from outside step, fixture block on slide bar 6 or bayonet lock still keep lockup state with hook tooth ring, in climbing process, BOGEY WHEEL 2 is in unidirectional rotation lockup state, when climbing machine climbing is to destination, vehicle frame is pulled forward to make roller 8 and earth surface, BOGEY WHEEL 2 removes unidirectional locking, vehicle frame can push-and-pull freely flexibly as required.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
