Abstract
The utility model relates to a control system for lifting and rotating stages, which belongs to the stage facility. The control system for lifting and revolving stages is composed of a hydraulic control system and a lifting mechanism. The utility model is characterized in that the inner side wall of a hollow piston connecting rod is provided with an anti-rotating shaft; the front end of the hollow piston connecting rod extends into a sliding groove which is arranged on the anti-rotating shaft; the lower end of the anti-rotating shaft is fixedly connected with the bottom of a hydraulic cylinder; a rotating mechanism comprises a variable-frequency speed-regulating motor and a worm gear and worm speed changer; the output end of the rotating mechanism is connected with a bearing seat which is connected with a platen through a belt. The utility model has the advantages of space saving, convenient installation, steady rising and falling rotation, no obvious impact, less oscillation, and reliable motion, and can meet all requirements of shows.
Description
The utility model relates to the control system of a kind of lifting, revolving stage, belongs to stage facility.Being particularly suitable on acrobatics team and central authorities, the local all kinds of stages of performing in a radio or TV programme the Room dress uses.
Increased and people's appreciation level improves constantly along with domestic and international cultural exchanges, the more and more requirement of equipment such as incompatibility modern sound, light, dance ﹠ art and stage property of fixed stage in the employed venue of domestic each performance group, the switching of the linking of each program and stage property, setting in the more incompatible performance.Therefore, domestic in recent years the beginning transformed the part venue, all liftings, revolving stage have occurred, once made positive contribution for adapting to the modernization performance.But, also exist the drawback that can not be ignored respectively.As mechanical elevator stage, huge, heavy because of its structure, transmission stability is poor, and speed adjusting difficulty etc. are all multifactor so be eliminated gradually; Mechanical hydraulic-pressure type and for example because of defective such as have the back flap hinge shelf structure under it or version such as band guide pillar etc. causes complex structure, and difficulty of construction is big.Owing to have exposedly outside below the lifting platen, so must block with weather screen below the stage, again in case influence stage integral body artistic effect than complex mechanical construction.The rotating mechanism of revolving stage in the past is generally the transmission of gear-wheel gear-ring formula simultaneously, the structure more complicated, and processing difficulties, and installation accuracy height are difficult for adjusting.Elevator stage in the past in addition, when climb was big, its swing, rolling momentum were bigger, and this just more can not satisfy the specific (special) requirements of high-leveled and difficult acrobatics action, thereby it is applied be subjected to certain limitation.
The purpose of this utility model is to provide that a kind of structure is light and handy, volume is little, be convenient to install, save space, lifting rotation steadily, do not have and obviously impact, swing little, technological performance, reliable in action can satisfy liftings of all performance requirements, the control system of revolving stage.
The purpose of this utility model realizes by the following technical solutions, form by hydraulic control system and stage lift structure, the madial wall of the hollow piston connecting rod that an end links to each other with piston in its described elevating mechanism is provided with anti-rotating shaft, front end puts in the chute of offering on the anti-rotation mandrel, fixedlys connected with the bottom of hydraulic cylinder in the lower end of anti-rotation mandrel; Described rotating mechanism comprises a frequency-conversion and speed-regulation motor, worm type of reduction gearing, output by belt with link to each other with bearing block that platen fuses.
The upper and lower side of described piston is respectively equipped with buffer plunger, and the upper and lower side inboard of hydraulic cylinder is provided with cushion collar.
The front end of described anti-rotating shaft is provided with bearing.
The utility model compared with prior art, owing to adopted hydraulic cylinder directly to drive stage, anti-rotation, buffer gear, nonstandard piston and a series of technical measures such as fairlead, lifting hydraulic speed regulating device and rotation frequency-conversion and speed-regulation motor with lengthening, and through evidence have simple in structure, volume is little, be convenient to install, save the space, the lifting rotation steadily, do not have and impact obviously that swing is little, the lifting rotation realizes stepless speed regulation, reliable in action, the performing artist is had a sense of security; Can realize simultaneously the single action of stage, two moving, synchronous lifting, rotation, speed governing, holding position etc. are multi-functional, can satisfy all kinds of performance needs.
Fig. 1 is a hydraulic control system schematic diagram of the present utility model.
Fig. 2 is the utility model buffering, anti-rotation part-structure schematic diagram.
Fig. 3 is the utility model lifting, rotating mechanism structural representation.
Fig. 4 is the embodiment that two actives of the utility model elevator stage can drive a passive stage.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, hydraulic control system comprise fuel tank 19, liquid level gauge 18, pressure meter switch 4, three electric-motor pumps 2,1 by pipeline 5 through plug-in mounting overflow valve 6,7,8 set up operating pressures after check valve 9,10 by reversal valve 11,16, unidirectional flow speed control valve 12,17, hydraulic control one-way valve 13 provides working media to hydraulic cylinder 14,3,15 respectively, realizes traffic direction, the speed of hydraulic cylinder 14,3,15 are controlled.Be provided with the piston 22 of nonstandard lengthening in the hydraulic cylinder 14,3 of elevating mechanism, two ends are provided with buffer plunger 23,28 up and down, hollow piston connecting rod 24 lower ends link to each other with piston 22, the upper end links to each other with platen 31 by bearing block 30, fixedly connected with the bottom of hydraulic cylinder 14,3 in the lower end of being located at the anti-rotation mandrel 27 in the hollow piston connecting rod 24, the inwall upper edge of hollow piston connecting rod 24 is axially arranged with several anti-rotating shafts 29, the bearing 26 of its front end puts in the chute of offering on the anti-rotation mandrel 27 25, and the upper and lower side inboard of hydraulic cylinder 14,3 is provided with cushion collar 37; Described rotating mechanism comprises frequency-conversion and speed-regulation motor 34, worm type of reduction gearing 33, and its output links to each other with the bearing block 30 that links to each other with platen 31 by belt 32.Elevator stage of the present utility model both can rotate in every independent lifting rotation, the lifting simultaneously of two portion, can drive synchronously riser platen 36 1 liftings of an a certain specification again with two stages, by the flexible realization of latch cylinder 15 control latches 35 and two stage platen 31 synchronization liftings or disengagement.Not only can be made into square, circle but also can make required shape on demand as for platen 31.
