Abstract
Disclosed is clamping type rigid support structures of an elevating stage. The elevating stage is driven to be elevated by a hoisting mechanism. The support structure comprises four sets which are symmetrically arranged around the stage. Each set comprises a stand column which penetrates through the stage, a hydraulic cylinder and a shifting fork, wherein an outer circle and a shifting ring are sleeved on a position, corresponding to the lower portion of the stage, of the stand column. When the elevating stage reaches a certain needed height through the hoisting mechanism, the tail ends of the shifting forks are pressed downward under synchronous work of the four hydraulic cylinders, the initiating ends of the shifting forks drive the shifting rings to move upward, and three clamping claws clamp the stand columns tightly under the function of a conical surface structure and form rigid support, and therefore the shake and the tilt of the stage surface can be effectively prevented, and using effect and safety of the stage can be improved.
Description
Technical field
The utility model relates to the braced structures that a kind of elevator stage is used.
Background technology
Traditional elevator stage is realized the lifting of stage by hoisting mechanism, when performance, because the elastic deformation of lift rope and pine stagnate and the discontinuity of table top, the problems such as rocking easily appears in table top, inclination affect performing effect, also have potential safety hazard simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiency that existing elevator stage exists, and provides a kind of and can make the firm clamping type rigidity supporting structure of elevator stage.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of clamping type rigidity supporting structure of elevator stage, described elevator stage drives lifting by hoisting mechanism, described supporting mechanism is four groups, be arranged symmetrically in stage around, described supporting mechanism includes column, hydraulic cylinder and the shift fork that runs through stage, and corresponding stage below is arranged with outer ring and ring on the described column; Described shift fork is positioned at the below of elevator stage, and the tail end of shift fork and the piston rod of hydraulic cylinder are hinged, and described hydraulic cylinder is hingedly mounted on the lower surface of elevator stage; The bearing affixed with stage is installed on the stage casing of described shift fork, and the initiating terminal of described shift fork is connected with the embedding of described ring phase; Be provided with jaw between corresponding outer ring and the ring on the described column, the endoporus of described outer ring is the taper seat structure, the outer face of described jaw is the taper seat structure, the internal conical surface coupling of described jaw outer conical surface and described outer ring offsets, described jaw lower end is provided with crotch, the inboard of described ring upper end is provided with the groove that closes with described crotch phase scarf, the side of described jaw is connected with extension spring, the outside of described ring is extended with lug, the other end of described extension spring is connected with described lug, original state, jaw and column are in free movement state; Described outer ring is affixed by erection loop and stage; Described four hydraulic cylinder synchronous motion.
Jaw on the described column is three, is evenly arranged.
The arc surface that jaw on the described column contacts with column has several separate slots.
The beneficial effects of the utility model are: when elevator stage arrives certain height that needs by hoisting mechanism after, synchronous working by four groups of hydraulic cylinders presses down the tail end of shift fork, the initiating terminal of shift fork drives on the ring and moves, three jaws are clamping to column under the cone structure effect, form rigid support, thereby effectively avoided rocking of stage table top, tilted, improved stage result of use and safety.
