Abstract
The invention discloses a clamping and fixing type rigid support structure for a liftstage. The liftstage is driven by a hoisting mechanism to lift; four groups of support mechanisms are symmetrically arranged around the liftstage; and each support mechanism comprises an upright post, a hydraulic cylinder and a shifting fork, wherein the upright post passes through the stage; and an outer ring and a toggle ring are sleeved on the upright post corresponding to the lower side of the stage. By the clamping and fixing type rigid support structure, when the liftstage is lifted to the required height by the hoisting mechanism, the tail end of the shifting fork is pressed downward by synchronous operation of the four group of hydraulic cylinders; the starting end of the shifting fork drives the toggle ring to move upwards; the upright post is clamped and fixed by three clamping jaws under an action of a conical surface structure to form rigid support, so that the shaking and the inclication of the liftstage surface can be effectively avoided, and the use effect and the safety of the liftstage are improved.
Description
Technical field
The present invention relates to the braced structures that a kind of elevator stage is used.
Background technology
Traditional elevator stage, realizes the lifting of stage by hoisting mechanism, in the time of performance, due to the elastic deformation of lift rope with pine is stagnant 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 present invention solves the deficiency that existing elevator stage exists, and provides a kind of and can make the clamping type rigidity supporting structure that elevator stage is firm.
The present invention solves the problems of the technologies described above adopted technical scheme:
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 the surrounding of stage, described supporting mechanism includes the column, hydraulic cylinder and the shift fork that run through stage, and on described column, corresponding stage below is arranged with outer ring and ring; 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; On described column, between corresponding outer ring and ring, be provided with jaw, the endoporus of described outer ring is taper seat structure, the outer face of described jaw is taper seat structure, described jaw outer conical surface is mated and is offseted with the internal conical surface of described outer ring, described jaw lower end is provided with crotch, the inner side of described ring upper end is provided with the groove closing 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 described column is three, is evenly arranged.
The arc surface that jaw on described column contacts with column has several separate slots.
Beneficial effect of the present invention is: when elevator stage arrives by hoisting mechanism after certain height needing, by the synchronous working of four groups of hydraulic cylinders, the tail end of shift fork is pressed down, the initiating terminal of shift fork drives on ring and moves, three jaws are clamping to column under cone structure effect, form rigid support, thereby effectively avoid rocking of stage table top, tilted, improved stage result of use and safety.
