Manual lifting hydraulic well lid
The invention discloses a manual lifting hydraulic well lid. The manual lifting hydraulic well lid comprises a handheld hydraulic rod, a power hydraulic cylinder, an execution cylinder and an execution rod, wherein the manual execution rod is arranged above the power hydraulic cylinder, a first oil passing hose is arranged below the power hydraulic cylinder, the first oil passing hose is connectedto an oil tank, a second oil passing hose is arranged at the rear end of the power hydraulic cylinder, the second oil passing hose is connected with the power hydraulic cylinder, the front end of thepower hydraulic cylinder is provided with a third oil passing hose, the third oil passing hose is connected with a fourth oil passing hose, the fourth oil passing hose is finally connected to an oilreceiving hole in the lower end of the execution cylinder, the execution rod is arranged in the execution cylinder, a movable well lid is arranged on the execution rod, an oil receiving hole in the upper end of the execution cylinder is connected with a fifth oil passing hose, and the fifth oil passing hose is connected to the oil tank. The manual lifting hydraulic well lid is simple in structureand convenient to operate, a well lid can be opened only by pressing down the manual execution rod in the implementation process, and labor is reduced.
本发明公开了一种手动升降液压井盖，包括手持液压杆，动力液压缸，执行缸和执行杆，所述动力液压缸上方设有手动执行杆，动力液压缸下方设有一号通油软管，且所述一号通油软管连接到油箱，所述动力液压缸后端设有二号通油软管，所述二号通油软管连接动力液压缸，所述动力液压缸前端设有三号通油软管，所述三号通油软管与四号通油软管连接，所述四号通油软管最终连接到执行缸下端接油孔，所述执行缸内设有执行杆，所述执行杆上设有活动井盖，所述执行缸上端接油孔连接五号通油软管，最后五号通油软管接到油箱。本发明结构简单，操作方便，在实施时只需要下压手动执行杆就可以打开井盖，减少人工。
