升降舞台设计要点分析

升降舞台http://www.sdsjpt.net/由台面、转轴、齿圈、滚柱组件、液压马达、键、底板、底座及均布于底座下方的驱动液压缸组成。四只伸缩式液压缸的活塞同步上升时,推动底座及舞台沿导轨竖直上升。舞台的旋转运动由可独立控制的液压马达驱动齿圈来实现。为有效降低摩擦阻力矩,在底座和台面间布置了滚柱组件,保证液压马达能够比较轻便地驱动舞台回转。
Landing stage by the table, the rotary shaft, the ring gear, the roller assembly, the hydraulic motor, the key, the bottom plate, the bottom of the base and uniformly distributed in the base of the drive hydraulic cylinder components. When four telescopic hydraulic cylinder piston rising, pushing the base and stage along the rail vertical rise. Rotational movement of the stage can be independently controlled by a hydraulic motor driving the ring gear to achieve. To effectively reduce the friction moment between the base and the table roller assembly arranged to ensure that the hydraulic motor can be driven relatively lightweight rotary stage.

升降舞台油泵电机启动后,双联油泵开始工作,但大流量泵和小流量泵均处于卸荷状态。舞台上升时,电磁铁得电,升降回路升压,大流量泵输出的液压油分别通过换向阀再经四个液控单向阀进入四个液压缸无杆腔,产生推力,克服舞台重量和导轨副摩擦推动舞台上升。因液压缸尺寸较大,舞台上升速度较慢,为减少液压元件的数量,保障系统的可靠性,不设置调速元件而采取由油泵和液压缸尺寸予以直接保证的设计方案。当舞台停止上升或到达最大行程时,电磁铁失电,换向阀处于左位,主回路卸压。
After landing stage pump motor starts to work a double-pump, but the pump flow and low flow pumps are in the unloading state. When the stage rises, the solenoid is energized, lifting loop boost, the flow of hydraulic oil pump output were re-enter through the valve through the four pilot-operated check valve four cylinder rod chamber to produce thrust to overcome the weight of the stage friction rail and push the stage rises. Due to the larger size of the hydraulic cylinder, the stage rises slowly, in order to reduce the number of hydraulic components to ensure the reliability of the system, do not set the speed element to be taken by the oil pump and hydraulic cylinder direct guarantee size design. When the stage is stopped up or reaching the maximum stroke solenoid YA6 energized, valve is in the left position, the main circuit relief.

升降舞台由于液控单向阀锁死,升降舞台停止在锁死位置;升降舞台下降时,电磁铁得电,系统控制回路升压,高压油进入液控单向阀的先导控制阀,将液控单向阀打开,同时得电,换向阀接油箱,舞台机械设备依靠自重下降。下降速度可由调速阀调定。同步控制:本系统四条同步支路所选用的元件型号相同、各支路输入流量相同,可以较好的保证四个伸缩式油缸的同步上升、同步下降。
Landing stage due to the check valve lock, landing stage stop in locked position; when the landing stage down solenoid is energized, the system control loop boost, high-pressure oil into the pilot check valve control valve, the liquid check valve is opened, while the electricity, fuel tank valve connection, stage machinery and equipment declined own weight. The rate of decline it is set by the governor valve. Synchronization control: the same branch of the system of choice of four synchronous component model, each branch of the same input flow, can better ensure the synchronization of the rise of the four telescopic cylinders, synchronized decline.

升降舞台http://www.sdsjpt.net/为使四个液压缸产生相同的推力,系统中采用四个单向阀将四条支路隔离开,然后用一个溢流阀进行压力控制,保证各支路设定压力相同。
Landing stage to make four cylinders produce the same thrust, the system uses four-way valve to isolate the four branches, and then use a pressure relief valve control, to ensure that each branch of the same set pressure.
