導軌式升降貨梯是日常高空作業(yè)中經(jīng)常用到的液壓升降平臺設備，應用場所和行業(yè)非常廣泛。導軌式升降機廠家濟南?？谱詣踊O備有限公司為您講解下導軌式升降貨梯的工作原理。

Guide rail cargo elevator is a hydraulic lifting platform equipment often used in daily high-altitude operation, which is widely used in many places and industries. Jinan Ruike automation equipment Co., Ltd., a manufacturer of guide rail elevator, explains the working principle of lower guide rail elevator for goods.

導軌式升降機工作原理是液壓油由葉片泵形成壓力，經(jīng)濾油器、隔爆型電磁換向閥、節(jié)流閥、液控單向閥、平衡閥進入液壓油缸下端，使液壓油缸的活塞向上運動，提升重物，液壓油缸上端回油經(jīng)隔爆型電磁換向閥回到油箱，其額定壓力通過溢流閥進行調(diào)整，通過壓力表觀察壓力表讀數(shù)值。

The working principle of the guide rail elevator is that the hydraulic oil forms pressure by the vane pump and enters the lower end of the hydraulic oil cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve and balance valve to make the piston of the hydraulic oil cylinder move upward and lift the weight. The return oil at the upper end of the hydraulic oil cylinder returns to the oil tank through the flameproof electromagnetic directional valve, and its rated pressure is adjusted through the overflow valve. Observe the reading value of the pressure gauge through the pressure gauge.

導軌式升降貨梯的單根鏈條拉力可達8噸，很難回斷裂，即使斷裂了，也不會像電梯一樣直接下墜，因為導軌式液壓升降貨梯是一種液壓設備，油缸，油管內(nèi)有液壓油，出現(xiàn)故障時回慢慢泄油，不會突然墜落，給工作人員留下足夠的時間解決問題，不會有意外情況發(fā)生。

The tension of a single chain of the guide rail type cargo elevator can reach 8 tons, which is difficult to break back. Even if it breaks, it will not fall directly like the elevator, because the guide rail type hydraulic cargo elevator is a kind of hydraulic equipment. There is hydraulic oil in the oil cylinder and oil pipe. When there is a fault, the oil will drain back slowly and will not fall suddenly, leaving enough time for the staff to solve the problem and there will be no accidents.

在使用導軌式升降貨梯升降平臺的過程中需嚴格遵守以下幾點：升降平臺由專人操作管理，開機前檢查鋼絲繩、地錨、纜風繩良好，空載運行合格方可使用。運料升降平臺嚴禁載人，在各種裝置可靠的情況下，卸料人員才能進入吊籃內(nèi)工作。禁止攀登升降平臺架體和架體下面穿越。

The following points shall be strictly observed in the process of using the lifting platform of the guide rail type goods elevator: the lifting platform shall be operated and managed by a specially assigned person. Before startup, check that the steel wire rope, ground anchor and cable wind rope are in good condition, and can be used only after passing the no-load operation. It is strictly forbidden to carry people on the material lifting platform. Only when various devices are reliable can the unloading personnel enter the basket to work. It is forbidden to climb the lifting platform frame and cross under the frame.
