Double-layer parking platform
The present invention relates to a kind of vehicle parking device, relate in particular to a kind of double-layer parking platform.
Existing garage parking, generally all parking side by side, take up space, if vertical pile needs to build corresponding floor in addition so and realizes that cost is higher, for this reason, disclose a kind of parking platform in the prior art, seen that the patent No. is Chinese invention patent " move rotate lifting no dodge type the upper-layer parking platform " (notice of authorization number: CN1284915C) disclose a kind of mobile rotation lifting no dodge type upper-layer parking platform, it is characterized in that of ZL200410026901.4; The moving guide rail of described mobile rotation lifting no dodge type upper-layer parking platform is fixed on the basis; Movable base connects with moving guide rail by shifting roller; Mobile motor is fixed on the movable base, connects with shifting roller by mobile tumbler; Rotary electric machine is fixed on the movable base, connects with column by rotation transmission device; Column connects with movable base by rolling bearing; Lifting motor is fixed on the column, connects with the lifting sprocket wheel by lifting actuator; Elevating chain is walked around the lifting sprocket wheel and is fixed on the lifting support; Lifting support connects with column by the lifting roller; The upper-layer parking platform biasing is fixed on the lifting support; Mobile motor drives movable base and moves along moving guide rail by mobile gear and shifting roller; Rotary electric machine drives column by rotation transmission device and rotates; Lifting motor drives the lifting sprocket rotation by lifting actuator, makes the upper-layer parking platform lifting by elevating chain and lifting support; Upper-layer parking platform by move, the aggregate motion of rotation and lifting, that realizes upper-layer parking platform puts down and packs up operation.When though this patent can realize upper-layer parking, the effect that lower floor's vehicle need not to dodge, the structure more complicated, cost is higher, also has many shortcomings: as adopting shifting roller and moving guide rail, slide easily, be not easy the location, influence is used; Adopt elevating chain, noise is big, and the lifting transmission is not steady; These all are unfavorable for promoting the use of, and need improve.
Summary of the invention
Technical problem to be solved by this invention be provide at the above-mentioned state of the art a kind of simple in structure, be easy to realize locate, the convenient double-layer parking platform that uses.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of double-layer parking platform, it comprises
The bottom parking platform;

Column is located on the aforesaid movable platform and relative movable platform can be rotated; And
Upper-layer parking platform can be arranged on the aforesaid column up and down,
It is characterized in that:
Movable platform and the mobile of bottom parking platform are set to:
Described movable platform is provided with mobile motor, mobile reducer and carrier wheel, and the power intake of aforementioned mobile reducer is connected with the clutch end of mobile motor, then is provided with aforesaid carrier wheel on the clutch end of mobile reducer;
Described bottom parking platform is provided with light rail, cooperate with pulley below the movable platform, and this light rail has the tooth bar with aforementioned carrier wheel engagement.Realize that with rack-and-pinion moving of ride can not produce rolling and skid, can guarantee that the operation of ride is smooth and easy.
The rotary setting of described column and movable platform is:
Described movable platform is provided with electric rotating machine, rotation reducer and swing pinion, and the power intake of aforementioned rotation reducer is connected with the clutch end of electric rotating machine, then is provided with aforesaid swing pinion on the clutch end of rotation reducer;
Described column bottom is provided with the internal gear with aforementioned swing pinion engagement.
The clutch end that described rotation reducer is an electric rotating machine connects an end of power transmission shaft by a universal joint, the other end of power transmission shaft connects an end of worm shaft again by another universal joint, worm shaft and worm gear engagement, be coaxially connected with swing pinion on the worm gear, worm shaft and worm gear are arranged on the movable platform by the bearing separately on the mount pad.
Be provided with rotary locking mechanism between the main shaft on described column bottom and the movable platform, rotary locking mechanism comprises the electromagnet that is fixed on the main shaft bottom, and pin is pegged graft with the equally distributed locating hole of column bottom circumference and cooperated on the electromagnet.
The lifting of described upper-layer parking platform and column is set to:
Described column is provided with lifting motor, train of reduction gears, screw rod and screw gear, the power intake of aforesaid train of reduction gears is connected with the clutch end of lifting motor, aforesaid screw gear be located on the screw rod and with the clutch end engagement of aforementioned train of reduction gears;
One cooperates nut and described upper-layer parking platform to realize lifting to fixedly install with aforementioned screw rod.
The shortcoming that bolt and nut promotes is that efficient is not high, and its advantage is: 1. utilize screw driven self-locking characteristics to brake; 2. safe and reliable, can not take place to weigh down situation soon, even screw rod fracture, in the middle of ride also can only be stuck in, perhaps nut lost efficacy, ride also can only slowly intermittently descend, or is parked in bottom and can not promotes.
A described upper-layer parking platform and a ride support connection of parallel column substantially, described nut then is located on this ride support.
Described screw rod upper end is fixed in the holder of column top by bearing, and gravity sensor is arranged between bearing and the holder.Gravity sensor guarantees that upper-layer parking platform can not promote under overweight situation, the sender of reporting to the police when overload is guaranteed safety.
At last, described screw rod is set in the fixed cover, and described nut is the spherical floating nut, and lining spherical floating pad is supported with disk spring between this spherical floating pad and the aforesaid fixed cover top on this spherical floating nut.
The purpose that the nut force side is designed to sphere and spherical pad is: the ride support is subjected to bias force and can guarantees that not therefore and influenced nut center of effort, guarantees that nut runs well with the stressed coaxial of screw rod when micro-corner is arranged.The purpose that butterfly spring is set on the spherical floating pad is to promote, and allows screw rod progressively load during beginning and protects motor and each member not to be subjected to big impact force.
Compared with prior art, the invention has the advantages that: overall structure is more reasonable, is easy to realize the location, in the time of reaching upper-layer parking simultaneously, and the effect that lower floor's vehicle need not to dodge, noise is few.
