Description

A kind of stereo parking garage lifting device flat bed mechanism

Technical field

The utility model relates to elevator technology field, is a kind of for promoting the flat bed mechanism of the elevator of automobile specifically, makes that four jiaos of vehicle-containings are synchronous and flat bed is more precise and stable.

Background technology

Due to the restriction of urban space, parking lot adopts three-dimensional parking garage to improve the utilization ratio in space, and this multi-storied garage consists of or floor-type garage parking steel framework support body conventionally.

Known, the hoisting mechanism that is used for the multi-storied garage of this number of plies more (more than 3 layers) adopts traction-type hoisting mechanism conventionally, mainly comprise vehicle-containing (being car), wire rope or steel band, balance weight mechanism etc., by traction machine, drive lifting (elevating mechanism that reel drives does not have balance weight mechanism etc., and rope capacity is limited, is only applicable to the number of plies 3 layers of following multi-storied garage seldom).The feature of this hoisting mechanism is that car Aspect Ratio is large, promotes thing (automobile) quality large.For example the patent documentation of publication number CN203112286U discloses a kind of side machine room traction-type car elevator, its technical scheme comprises traction machine, car, counterweight, wire rope, directive wheel etc., car adopts 4 ﹕ 1 to hang ratios, and the defect of this hoisting mechanism is when cabin uneven loading, and the guidance system power that irreducible water square makes progress is completely poor, thereby car can not maintenance level while causing moving or after stopping, and four jiaos of synchronisms are bad; Secondly, after Elevator landing, its stopping device (normally friction-type normally closed brake) is to act in traction machine rotating shaft, by the indirect stop cab of wire rope, in vehicles while passing car process, because load-carrying changes, the wire rope physics causing stretches or traction sheave slippage causes the flat bed discrepancy in elevation further to strengthen, so not only affect vehicles while passing, and cause potential safety hazard.The patent documentation of publication number CN103225433A discloses a kind of parking systems rack-and-pinion lift-type lift platform, its technical scheme is at garage column stationary rack, car installing wheel and rack coordinates, then in cab bottom, arrange San Tao turbine and worm mechanism, reducing gear, motor direct-drive quadruplet pinion and rack for bevel gear etc., this prior art has solved the problem of car synchronous operation, Dan Qi mechanism is too complicated, and directly at car bottom electricity consumption machine, drive drive link along gear rack elevating, this type of drive is not established counterweight, the carrying means such as wire rope are only applicable to three layers of following multi-storied garage, not high with respect to its safety of multi-storied garage that the number of plies is more, generally can not adopt, the 3rd, after flat bed, during vehicles while passing, cab load changes, and cab still exists the slippage of above-below direction, causes flat bed difference in height, has potential safety hazard.

So those skilled in the art are necessary to improve the design of this elevating mechanism, eliminate safe hidden trouble.

Summary of the invention

For the defect of above-mentioned prior art and the technical problem of existence, the technical problem that the utility model solves is to provide a kind of simple in structure, when after the good and flat bed of cab synchronism, cab load changes, can there is not the flat bed mechanism for stereo parking garage lifting device of the slippage of above-below direction in cab.

The technical scheme of the utility model technical solution problem is: a kind of flat bed mechanism for stereo parking garage lifting device, comprises frame body; Vehicle-containing, traction machine, counterweight is by hoist ropes, and guiding mechanism is connected into one; It is characterized in that aforementioned vehicle-containing two bottom sides limit is symmetrically fixed with longitudinal drive link, its end is fixed with spur gear and meshes with the tooth bar being fixed on aforesaid frame body column; Between described longitudinal drive link, be also furnished with horizontal drive link, its end and described longitudinal drive link link into an integrated entity by the bevel gear of two pairs of engagements; Described horizontal drive link is fixed with a band-type brake dish, and it coordinates with contracting brake for locking the rotation of horizontal drive link.

Technique effect of the present utility model is: first the technical program adopts rack and pinion mechanism, has solved four jiaos of nonsynchronous technical problems of cab, the prior art of comparing, and its mechanism is more simple and practical, has saved cost; Secondly, this mechanism sets up brake sticking brake mechanism, when elevating mechanism flat bed, contracting brake locking band-type brake dish, each drive link can not be rotated, gear rests on tooth bar, be equivalent to vehicle-containing and frame body is rigidly connected, like this, when vehicles while passing cab, even if wire rope has necessarily flexible or traction sheave to have certain slippage, cab is not slippage up and down also, and it still can keep the accuracy of flat bed, there will not be cab load variations and the flat bed difference in height that produces, the potential safety hazard that exists of having eliminated prior art, has outstanding technological progress.

Preferred technical scheme: aforementioned longitudinal drive link is along the longitudinal side of described vehicle-containing by bearing, and bearing support is fixed.

Preferred technical scheme: aforementioned contracting brake is connected with lifting gear main controller signal.

Preferred technical scheme: aforementioned band-type brake dish is arranged in described horizontal drive link centre position.

Preferred technical scheme: aforesaid frame body can replace to hoistway, and aforementioned tooth bar can be fixed on four jiaos of hoistway.

Further technique effect: this is another kind of preferred embodiment of the present utility model, and it is changed a little and can use at wall tunnel type car elevator, and can not be confined to type solid frame parking lot.

Preferred technical scheme: aforesaid gears, tooth bar can be used sprocket wheel and chain to replace.

Further technique effect: this is another kind of preferred embodiment of the present utility model.
