Abstract
The utility model relates to the technical field of machinery, and relates to a lifting stage, in particular to a lifting device for the lifting stage. The lifting device comprises a fixed plate arranged on the horizontal plane, a lifting plane is arranged on the fixed plate, the lifting plane is connected with the fixed plate through two supporting rods which are adjustable in height, the two supporting rods are hinged together and are hinged to the same side of the lifting plane and the fixed plate, the other sides of the two supporting rods are connected with the lifting plane and the fixed plate respectively through rolling wheels in a rolling mode, and one end of each supporting rod is connected with an output shaft of a motor through a gear. The lifting device for the lifting stage has the advantages that through balance weights, pressure borne by the motor in the lifting process can be reduced, the service life of the motor can be prolonged, and the supporting rods which are connected in a staggered mode can enable the whole structure to be evenly stressed and to be compact.
Description
Technical field
The utility model relates to field of mechanical technique, about a kind of elevating stage, especially about a kind of jacking equipment for elevator stage.
Background technology
Stage is the space providing for actor performance in theater, and it can make spectators' the performance of concentrating on performer and obtain desirable appreciation effect.The type of stage has picture-frame stage, extended position stage, circular ring type stage and rotary-type stage.Stage consists of one or more platforms conventionally, and wherein a suitable stage can be realized the functions such as lifting, and it is also many to realize the mode of lifting.Such as, by oil pressure, realizing lifting is the mode of comparatively commonly using, and in addition, also has some lifting ropes, the modes such as interlock track.No matter be which kind of up-down mode principal security 2 points, one wants to realize the lifting of stage, and two will guarantee the performance safety of elevator stage.Obviously current elevator stage all can reach above-mentioned requirement, day by day maturation along with scientific and technological development and market, only reach that above-mentioned requirements seems and perfect not, more or less exist comparatively speaking some and do not live part, such as hydraulic drive seemed slow sometimes, efficiency is not very high, and the noise of interlock track in lifting process is larger, structure cannot realize compactness, easily the phenomenon such as loosening.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, compact conformation, and efficiency is high, the jacking equipment of the elevator stage that safety factor is high.
For achieving the above object, the utility model has adopted following technical proposal: a kind of jacking equipment for elevator stage, comprise the fixed head being arranged on horizontal plane, this fixed head is provided with lifting plane, it is characterized in that, between described lifting plane and fixed head, by realizing two support bars of height change, connect, two described support bars are hinged, and be hinged on respectively the same side of lifting plane and fixed head, the opposite side of two support bars is rolled and is connected with fixed head with lifting plane respectively by roller, one end of described support bar is connected with the output shaft of motor by gear one.
At above-mentioned a kind of jacking equipment for elevator stage, described motor is arranged in support, and this support is provided with gear two, between described gear two and output shaft, is provided with chain, and described chain is connected with lifting plane.
At above-mentioned a kind of jacking equipment for elevator stage, described support upper end is also provided with gear three and gear four, on described gear three and gear four, is overlapped with chain, and this chain one end is connected with lifting plane, and the other end is connected with counterweight.
A kind of jacking equipment for elevator stage above-mentioned, is also provided with rubber wheel on described support.
A kind of jacking equipment for elevator stage above-mentioned, is provided with guide rail between described roller and lifting plane; Between described roller and fixed head, be provided with guide rail.
At above-mentioned a kind of jacking equipment for elevator stage, described two support bars hinged being " X " type.
Compared with prior art, the utility model has the advantage of: the technical program can alleviate by counterweight the pressure that in lifting process, motor bears, can extend the service time of motor, by support bar, be cross-linked in addition that can to realize overall structure stressed evenly, compactness.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of jacking equipment for elevator stage, comprise the fixed head 1 being arranged on horizontal plane, this fixed head is provided with lifting plane 2, between lifting plane and fixed head, by realizing two support bars 3 of height change, connect, two described support bars are hinged, and be hinged on respectively the same side of lifting plane and fixed head, described two support bars hinged being " X " type, the opposite side of two support bars is rolled and is connected with fixed head with lifting plane respectively by roller 4, one end of described support bar is connected with the output shaft 6 of motor by gear 1.Between described roller and lifting plane, be provided with guide rail 7; Between described roller and fixed head, be provided with guide rail.By the rotation of output shaft, just can realize support bar and rotate a certain angle, two support bars that are at this moment " X " type just can be realized the movement in vertical direction, thereby drive the liter of lifting plane or fall.
Motor is arranged in support 8, and this support is provided with gear 29, between described gear two and output shaft, is provided with chain 10, and described chain is connected with lifting plane.The rotation of chain can drive moving up and down of lifting plane, plays the gravity of lifting plane and the effect of insurance of sharing.Described support upper end is also provided with gear 3 11 and gear 4 12, on described gear three and gear four, be overlapped with chain, this chain one end is connected with lifting plane, the other end is connected with counterweight 13, this counterweight can play the effect of stable elevation plane in the process of lifting, in addition, easy of rise plane is up drawn.On described support, be also provided with rubber wheel 14, by rubber wheel, can play tension, avoid chain absent-mindedness.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
