Description
Technical field
The present invention relates to a kind of lowering or hoisting gear, a kind of stable drive, lifting platform convenient to operate, belong to load-carrying transmission art field.
Background technology
Lowering or hoisting gear is widely applied in life and commercial production, and the height that object bigger for some weight is transported to some can be beyond one's reach on position by people by lowering or hoisting gear；More existing small-sized lowering or hoisting gears cannot carry heavy objects, and the scope lifted is less；And some load-carryings are effective, the usual assembly of lowering or hoisting gear that range is big is many, and structure is complicated, is not easy to operation.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of stable drive, lifting platform convenient to operate.
The technical solution of the present invention is achieved in that a kind of lifting platform, comprises carrying board, base plate, transmission component and least one set lifting assembly；Described carrying board is arranged on the upside of base plate；Described lifting assembly is arranged between carrying board and base plate；Each group of lifting assembly all comprises two hinged support arms that intersect；End with two support arms respectively, the two ends of described transmission component is connected;Described lifting assembly has two groups, and two groups of lifting assemblies are arranged side by side along same centrage;Described transmission component comprises motor and two groups of transmissions；It is provided with shaft coupling on the main shaft of described motor, shaft coupling is provided with master bevel gear；Transmission described in each group all comprises a crossbeam and a screw mandrel；Threadeding with crossbeam in one end of described screw mandrel, the other end of screw mandrel is provided with secondary bevel gear；Described secondary bevel gear engages with master bevel gear；Two crossbeams of described two groups of transmissions are positioned in same level, and different from the same lifting assembly respectively support arm of two crossbeams is connected;The upper end of every described support arm is provided with roller, and the lower end of every support arm is all hinged on corresponding crossbeam；The two ends of every described crossbeam are provided with roller;It is provided with slide rail on described carrying board and base plate；Each described roller is arranged in corresponding slide rail.
Preferably, described base plate is provided with limited block；It is provided with block on the corner of described base plate.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The lifting platform of the present invention, by gear and screw rod transmission, makes two support arms intersected rotate in hinged place, and then drives carrying board to rise or fall, carrying board can be placed weight, thus reach the purpose of lifting；Overall simple in construction, easily operates, and load-carrying is effective, and stable drive.
