Abstract
The utility model relates to a guide rail mechanism, which comprises a rack, a gear and a rack, wherein the rack is positioned above a pair of rollers. The guide rail mechanism also comprises a guide rail which is arranged in parallel with the rack. A guide wheel matched with the guide rail is arranged on the guide rail, and is coaxial with the gear. The guide rail is separated from the rack, and is parallel to the rack, and the guide wheel coaxial with the gear runs along the guide rail, so that the phenomena of offset and derailment in the prior art are avoided, and the gear can be meshed with the rack more accurately; and a groove matched with the guide rail is formed on the outer peripheral surface of the guide wheel, and an angle of the guide wheel can be changed when running along the guide rail, so that the motion stability of a power-assisted lift is improved, and the safety of passengers is ensured.
Description
Technical field
The utility model relates to the conveying track field, especially a kind of guide rail mechanism.
Background technology
At present, power-assisted ladder commonly used can adopt multiple type of drive that it is moved along guide rail, and the effect of guide rail is that various chair lifts can be moved along guide rail back and forth.The operation form of guide rail generally adopts rack and pinion drive mechanism, and tooth bar is welded on the top of guide rail, and the rotation through gear realizes that tooth bar moves around, and moves back and forth along guide rail thereby drive power-assisted ladder chair lift.Because guide rail generally extends along the stair abutment wall, acclivitous angle and angle of turn is arranged, in operational process; Especially in angled place, the engaged transmission between the wheel and rack is prone to produce skew, the phenomenon of derailing; Also can there be deviation in its angle, has brought potential safety hazard then for the power-assisted ladder.
The utility model content
The applicant can produce the shortcoming of shift phenomenon to the guide rail in the above-mentioned existing production, guide rail mechanism a kind of rational in infrastructure, easy to operate is provided, thereby improves mechanism stability, and guide rail moves freely, can not produce the out-of-position phenomenon, and cost is low.
The technical scheme that the utility model adopted is following:
A kind of guide rail mechanism comprises frame, gear and tooth bar, and said tooth bar is positioned at the top of a pair roller; Also comprise the guide rail that laterally arranges with tooth bar, guide wheel with matching is installed on the said guide rail, said guide wheel is coaxial with gear.
It is further characterized in that:
The outer circumference surface of said guide wheel is provided with the groove that matches with guide rail.
The beneficial effect of the utility model is following:
The utility model separates guide rail with tooth bar, make guide rail be parallel to tooth bar, through moving along guide rail with the coaxial guide wheel of gear; Avoided to produce in the prior art phenomenon of skew, derailing; Make wheel and rack engagement more accurate,, make it can the conversion of translation-angle simultaneously when guide rail moves because the guide wheel outer circumference surface is provided with the groove that matches with guide rail; Improve the robust motion of power-assisted ladder, guaranteed passenger's safety.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model pinion and rack and guide rail.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
The described guide rail mechanism of the utility model comprises frame 4, gear 1 and tooth bar 2, and tooth bar 2 is positioned at the top of a pair roller 3; Also comprise the guide rail 5 that laterally arranges with tooth bar 2, guide wheel 6 with matching is installed on the guide rail 5, guide wheel 6 is coaxial with gear 1, and the outer circumference surface of guide wheel 6 is provided with the groove 7 that matches with guide rail 5.
In the actual use, actuating device driven wheel 1 rotates, and rotates with gear 1 coaxial guide wheel 6 simultaneously; Thereby produce gear 1 and tooth bar 2 engaged transmission simultaneously, guide wheel 6 moves on guide rail 5, when running to bend; Guide wheel 6 can be followed gear 1 translation-angle simultaneously through the radian of guide rail 5; Its engaged transmission is more accurate, has improved transmission stability, and cost is low.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
