如何有效地防止手電兩用啟閉機引起的事故是許多使用者都必須面對的問題。目前，家用手電兩用啟閉機結構簡單，安裝方便，價格低廉，在引水樞紐中得到了廣泛的應用。但是，當前使用的一些手電兩用啟閉機沒有有效的保護措施來防止啟閉機的事故。即使限位開關安裝在手電兩用啟閉機上，也只能起到限制作用。在起重作業(yè)過程中，會略有粗心地發(fā)生彎曲螺釘，頂部折斷的起重端蓋，頂部折斷的起重梁會引起鋼筋混凝土梁上緣的開裂和破壞，并會發(fā)生嚴重的起重。關閉平臺（梁）的移位，旋轉和翻倒甚至可能造成人員傷亡。手電兩用啟閉機還可能導致電動機過載并燒毀電動機，從而嚴重影響項目的安全運行，并威脅到操作人員的人身安全。在使用手電兩用啟閉機的過程中，一些小型和中型的儲罐已經連續(xù)翻轉了高架制動器，這表明手電兩用啟閉機易于造成高架事故。為了解決這一突出問題，應采取措施防止水閘事故的發(fā)生。
How to effectively prevent accidents caused by the dual use hoist is a problem that many users must face. At present, the household flashlight dual purpose hoist has a simple structure, convenient installation, and low price, and has been widely used in water diversion hubs. However, some currently used hand and electric dual purpose hoists do not have effective protective measures to prevent accidents with hoists. Even if the limit switch is installed on a manual and electric dual purpose hoist, it can only play a limiting role. During the lifting operation, there may be slight carelessness in bending screws, broken lifting end caps at the top, and broken lifting beams at the top, which can cause cracking and damage to the upper edge of the reinforced concrete beam and lead to serious lifting. The displacement, rotation, and overturning of the closed platform (beam) may even cause casualties. The manual and electric dual purpose hoist may also cause motor overload and burn out, seriously affecting the safe operation of the project and threatening the personal safety of operators. During the use of a dual purpose hoist, some small and medium-sized storage tanks have continuously overturned the overhead brakes, indicating that the dual purpose hoist is prone to causing elevated accidents. To address this prominent issue, measures should be taken to prevent the occurrence of water gate accidents.
檢修是檢測和修理的簡稱。通過檢測發(fā)現設備的故障、隱患和存在的問題，為修理提供依據。通過修理，解決存在問題，使其恢復原有的性能。
Maintenance is the abbreviation for inspection and repair. By detecting equipment faults, hidden dangers, and existing problems, a basis is provided for repair. By repairing, solve existing problems and restore its original performance.

Detection includes inspection, measurement, and fault analysis. The so-called inspection is generally carried out through intuitive methods such as looking, touching, listening, and smelling, that is, "looking at its surface, feeling its temperature, listening to its sound, and asking its taste", to check the condition of the equipment
