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 is through the up-down of hoisting mechanism realization stage, when performance; Because the elastic deformation of lift rope stagnates with pine and the discontinuity of table top; Problems such as rocking appears in table top easily, inclination influence 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 firm clamping type rigidity supporting structure of elevator stage.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of clamping type rigidity supporting structure of elevator stage; Said elevator stage drives through hoisting mechanism; Said supporting mechanism is four groups; Be arranged symmetrically in stage around, said supporting mechanism includes column, hydraulic cylinder and the shift fork that runs through stage, corresponding stage below is arranged with outer ring and ring on the said column; Said 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 said hydraulic cylinder is hingedly mounted on the lower surface of elevator stage; The bearing affixed with stage is installed, the initiating terminal of said shift fork and the embedding connection mutually of said ring on the stage casing of said shift fork; Be provided with jaw between corresponding outer ring and the ring on the said column, the endoporus of said outer ring is the taper seat structure, and the outer face of said jaw is the taper seat structure; The internal conical surface coupling of said jaw outer conical surface and said outer ring offsets; Said jaw lower end is provided with crotch, and the inboard of said ring upper end is provided with and the said crotch groove that closes of scarf mutually, and the side of said jaw is connected with extension spring; The outside of said ring is extended with lug; The other end of said extension spring is connected with said lug, original state, and jaw and column are in free movement state; Said outer ring is affixed through erection loop and stage; Said four hydraulic cylinder synchronous motion.
Jaw on the said column is three, evenly arranges.
The arc surface that jaw on the said column contacts with column has several separate slots.
Beneficial effect of the present invention is: after elevator stage arrives certain height that needs through hoisting mechanism; Synchronous working through four groups of hydraulic cylinders presses down the tail end of shift fork, and the initiating terminal of shift fork drives on the ring and moves, three jaws under the cone structure effect to the column clamping; Form rigid support; Thereby effectively avoided rocking of stage table top, tilted, improved stage result of use and safety.
