Abstract

The invention discloses an electric lifting platform which comprises an object table, a bottom plate, a transmission assembly and at least one lifting assembly. The object table is arranged on the upper side of the bottom plate. The lifting assemblies are arranged between the object table and the bottom plate. The transmission assembly is arranged at one end of the bottom plate. Each lifting assembly comprises a first supporting arm and a second supporting arm, wherein the first supporting arm and the second supporting arm are hinged to each other in an intersecting mode; the two ends of the first supporting arm are hinged to the object table and the transmission assembly respectively; one end of the second supporting arm is hinged to the bottom plate, and the other end of the second supporting arm is a free end. According to the electric lifting platform, the first supporting arms and the second supporting arms in intersection are pushed by the transmission assembly to rotate at the hinging positions, so that the object table is driven to ascend or descend; a heavy object can be placed on the object table, so that the purpose of lifting or dropping the object is achieved; the electric lifting platform is simple in overall structure, easy to operate, good in load bearing effect, and smooth in transmission.

Description

A kind of electric lifting platform

Technical field

The present invention relates to a kind of jacking system, particularly the electric lifting platform of a kind of stable drive, convenient operation, belongs to load-carrying driving device technical field.

Background technology

Jacking system is application widely in life and commercial production, and the height that people can be transported to some by the larger object of some weight by jacking system is beyond one's reach on position; More existing small-sized jacking systems cannot carry heavier object, and the scope of lifting is less; And some load-carryings are effective, the common assembly of jacking system that range is large is many, and complex structure is not easy to operation.

Summary of the invention

Technical matters for above-mentioned existence, the object of the invention is: the electric lifting platform that has proposed a kind of stable drive, convenient operation.

Technical solution of the present invention is achieved in that a kind of electric lifting platform, comprises objective table, base plate, transmission component and at least one group of lifting assembly; Described objective table is arranged on the upside of base plate; Described lifting assembly is arranged between objective table and base plate; Described transmission component is arranged on one end of base plate; The described lifting assembly of each group all comprises the first hold-down arm and second hold-down arm of two mutual cross-articulation; The two ends of described the first hold-down arm are hinged on respectively on objective table and transmission component; One end of described the second hold-down arm is hinged on base plate, and the other end is free end.

Preferably, described lifting assembly has two groups, and two groups of lifting assemblies are arranged side by side along same line of centers.

Preferably, described transmission component comprises motor and slide plate; On the main shaft of described motor, be provided with coupler, on coupler, be provided with screw mandrel; Described slide plate is slidably disposed on base plate; Described screw mandrel is threaded with slide plate; The two ends of described the first hold-down arm are hinged on respectively on objective table and slide plate.

Preferably, on the free end of described the second hold-down arm and slide plate, be provided with roller.

Preferably, on described base plate, be provided with chute; Roller on described slide plate is arranged in chute.

Preferably, on the lower surface of described objective table, be provided with block.

Preferably, be provided with back-up block on four of described base plate jiaos.

Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:

Electric lifting platform of the present invention, by coordinating of screw mandrel and slide plate, the first hold-down arm and the second hold-down arm that promote two intersections rotate in hinged place, and then drive objective table to rise or decline, and can place weight, thereby reach the object of lifting on objective table; Whole is simple in structure, easy to operate, and load-carrying is effective, and stable drive.

The structural representation that accompanying drawing 1 is a kind of electric lifting platform of the present invention;

The base plate that accompanying drawing 2 is a kind of electric lifting platform of the present invention and the schematic diagram of transmission component;

Wherein: 1, objective table; 2, base plate; 3, the first hold-down arm; 4, the second hold-down arm; 5, motor; 6, slide plate; 7, coupler; 8, screw mandrel; 9, chute; 10, block; 11, back-up block.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is described.

As shown in Figure 1-2, a kind of electric lifting platform of the present invention, comprises objective table 1, base plate 2, transmission component and two groups of lifting assemblies; Described objective table 1 is arranged on the upside of base plate 2; Described lifting assembly is arranged between objective table 1 and base plate 2; Described transmission component is arranged on one end of base plate 2; Two groups of lifting assemblies are arranged side by side along same line of centers, and each group lifting assembly all comprises the first hold-down arm 3 and second hold-down arm 4 of two mutual cross-articulation; Described transmission component comprises motor 5 and slide plate 6; On the main shaft of described motor 5, be provided with coupler 7, on coupler 7, be provided with screw mandrel 8; Described slide plate 6 is slidably disposed on base plate 2; Described screw mandrel 8 is threaded with slide plate 6; The two ends of described the first hold-down arm 3 are hinged on respectively on objective table 1 and slide plate 6; One end of described the second hold-down arm 4 is hinged on base plate 2, and the other end is free end; On the free end of described the second hold-down arm 4 and slide plate 6, be provided with roller; On described base plate 2, be provided with chute 9; Roller on described slide plate 6 is arranged in chute 9; On the lower surface of described objective table 1, near on the free-ended position of the second hold-down arm 4, be provided with block 10; On four jiaos of described base plate 2, be provided with back-up block 11.
