機(jī)架是固定卷揚(yáng)式啟閉機(jī)各部件的墊板，在加工時，各部件加工面之間的的相對高度誤差應(yīng)小于1.0nm。鋼絲繩應(yīng)該與GB/T8918的規(guī)定一樣，并且鋼絲繩在運(yùn)輸、出廠、存放過程中，應(yīng)該卷成盤形，在鋼絲繩表面涂油，兩端扎緊并帶有標(biāo)簽，鋼絲繩禁止接長使用。
The rack is a base plate for fixing various components of the winch hoist. During processing, the relative height error between the processing surfaces of each component should be less than 1.0nm. The steel wire rope should be in accordance with the provisions of GB/T8918, and during transportation, delivery, and storage, the steel wire rope should be rolled into a disc shape, coated with oil on the surface of the steel wire rope, tied tightly at both ends and labeled. The steel wire rope should not be extended for use.
固定卷揚(yáng)式啟閉機(jī)利用滑輪組上的動滑輪上的吊具和閘門相連接，用來啟閉閘門。這種方式的工作原理：電機(jī)驅(qū)動制動減速器和輪聯(lián)軸器使開式齒輪副和卷筒轉(zhuǎn)動，滑輪和平衡滑使輪卷筒上的鋼絲繩進(jìn)行吊具的陽雕刻 手套生產(chǎn)設(shè)備 果樹反光膜 北京純水設(shè)備 保定網(wǎng)站制作 排水槽模提升。一般情況下，絞車提升機(jī)不適合使用單滑輪組。因?yàn)樵谔嵘蚪档烷l門的過程中，單個滑輪組會使閘門水平移動，從而導(dǎo)致閘門晃動。當(dāng)雙滑輪組工作時，不會出現(xiàn)這種現(xiàn)象。此外，滑輪組的倍率應(yīng)均勻，避免了因鋼絲繩的牽引而造成的動滑輪的扭轉(zhuǎn)，平衡滑輪安裝在天車上，可用于操作限載器。
The fixed winch hoist is connected to the gate using a lifting device on the movable pulley of the pulley block to open and close the gate. The working principle of this method: the motor drives the brake reducer and wheel coupling to rotate the open gear pair and the drum, while the pulley and balance slide lift the steel wire rope on the drum for lifting. In general, a winch hoist is not suitable for using a single pulley block. Because during the process of lifting or lowering the gate, a single pulley block will cause the gate to move horizontally, resulting in gate shaking. This phenomenon does not occur when the double pulley block is working. In addition, the magnification of the pulley block should be uniform to avoid twisting of the moving pulley caused by the traction of the steel wire rope. The balance pulley is installed on the crown block and can be used to operate the load limiter.
