Comb lifting type automobile carrier
Technical field
The utility model relates to a kind of automobile carrier, is specifically a kind ofly applicable to the automobile-used comb lifting type automobile carrier of three-dimensional intelligent machine formula parking equipment access, belongs to parking equipment technical field.
Background technology
In the intelligentized mechanical parking equipment of large warehoused class, need the automobile carrier that equipment runs by programme controlled automatic intelligent, the automobile intelligent carrier comparatively generally adopted at present mainly contains vehicle-containing type, interdigitated electrode structure and embraces clip wheel fetalism.
Interdigitated electrode structure intelligent carrier mainly utilizes the fixed fingers frame on parking space and the upper and lower crisscross motion of lifting comb on carrier, completes the access procedure of vehicle.Due to can direct carrying vehicle, so efficiency high speed is fast, becomes in current multi-storied garage and apply the most general a kind of car carrying mode.
The operating principle of interdigitated electrode structure intelligent carrier is, the comb on car bearing platform, parking space and carrier is worked in coordination, and the comb on the comb of carrier and car bearing platform, parking space is interlaced.Carrier is below car bearing platform at ordinary times, during bicycle parking, automobile parking is on the car bearing platform on doorway, garage, and the wheel of automobile is on the fixed fingers frame of car bearing platform, elevating mechanism on carrier makes crane rise, after lifting comb on crane is held up together with automobile, elevating mechanism stops driving, and walking mechanism starts action, carrier by car carrying to parking space, walking mechanism stops, and elevating mechanism makes crane decline, and after down maneuver completes, carrier exits parking space.When picking up the car, carrier is introduced into parking space, and crane rises again, and after the lifting comb on crane is held up together with automobile, carrier carries automobile and exits parking space, and under crane, general who has surrendered's automobile is placed on the car bearing platform on doorway, garage, and car can drive away by driver.
Visible, no matter be bicycle parking or pick up the car, all need the elevating mechanism action on carrier, crane is made to drive the lifting comb on it to rise or decline, elevating mechanism action relates to lifting jack and guiding device two kinds of critical components, lifting jack generally adopts eccentric wheel or rack-and-pinion drive crane to rise or decline, adopt guide pillar guide pin bushing guiding simultaneously, as State Intellectual Property Office disclosed in 19 days Augusts in 2009 by Zhang Mingqin, the design such as Han Lifang, the patent No. is 200710114715.X, name is called the patent of invention of vehicle carrier of fork comb type multi-storied garage, this carrier adopts eccentric wheel drive crane to rise or decline, " slip pin 18 between crane and underframe, is adopted to connect ".For another example State Intellectual Property Office disclosed in the 19 days November in 2014 by the designs such as lofty, Wu Duojin, application number is 201410363247.X, name is called a kind of class multi-storied garage transfer robot of storing in a warehouse application for a patent for invention, this carrier adopts rack-and-pinion drive crane to rise or decline, adopt guide rod guide bracket guiding simultaneously, " guide rod 11 and be nested with the movable guide bracket 10 on location guide 11; middle part being arranged on supporting trolley underframe 20 that described location guide 11 is fixing, described movable guide bracket 10 is fixedly mounted on lifting frame 23 ".
Because vehicle body and crane are all be welded by section bar usually, on-mechanical processing structure, guide pillar, guide pin bushing adopt welding or bolted method to be individually fixed on the non-machined surface of vehicle body and crane, make said structure there is following common problem:
One is that installation accuracy requires high, installation complexity, debug difficulties, the guide pillar adopted, guide pin bushing logarithm more Installation and Debugging difficulty is larger, as documents 1 have employed 4 pairs of guide pillars, guide pin bushing, if ensure often pair of guide pillar, guide pin bushing all keeps being slidably matched to obtain higher positioning precision, often pair of guide pillar again, guide pin bushing all runs sliding smooth, it is the difficult problem faced by mechanical parking equipment manufacturing, although adopt the method for machine industry pairing processing, often will overlap vehicle body and process guide pillar together with crane pairing, the installing hole of guide pin bushing can solve the problem, but processing cost is high, production efficiency is low, be not suitable for undoubtedly using in mechanical parking equipment manufacturing,
Two is that operational failure rate is high, and maintenance cost is large; After carrier comes into operation, the welding stress of vehicle body and crane can discharge gradually, light then occur guide pillar, guide pin bushing run bite, heavy then cause crane can not realize moving up and down and cannot working, even occur guide pillar, guide pin bushing and vehicle body or crane weld snap, the fault such as connecting bolt fracture.
