Abstract

The invention provides an overturning walking device for a hoist oil cylinder and a method. The overturning walking device for the hoist oil cylinder comprises a walking platform, one end of the walking platform is provided with a hinged overturning platform, the overturning platform is provided with a plurality of locking mechanisms, a mounting platform at the end part of the overturning platform is provided with a rotatable fixing seat, the end part of the oil cylinder is axially fixed in the fixing seat, the oil cylinder abuts against the locking mechanisms and is fixed in the radial direction, a fixing mechanism is fixedly arranged on the oil cylinder, two expansion sleeves in the fixing mechanism are fixed to a piston rod and a cylinder body of the oil cylinder respectively, and the two expansion sleeves are fixedly connected through a connecting shaft so that the piston rod of the oil cylinder can be fixedly connected with the cylinder body; and a crane moves the vertical oil cylinder to the overturning platform, the vertical oil cylinder is fixed through the locking mechanisms and the fixing seat, a lifting rope of the crane is released and the walking platform is driven to move, the overturning platform can drive the oil cylinder to rotate until the oil cylinder lies on the walking platform, and on the contrary, the lifting rope of the crane is wound and the walking platform is driven to move, and the oil cylinder lying on the walking platform can be lifted to be in a vertical state.

Description

technical field [0001] The invention relates to the field of oil cylinder overturning, in particular to an overturning traveling device and method for an oil cylinder of a hoist. Background technique [0002] The hydraulic pressure hoist of hydropower station is a new type of hoist machinery integrating machine, electricity, hydraulic and instrument. It is an assembly with hydraulic cylinder as the main body, oil pump, oil tank, oil filter and hydraulic control valve. As the main equipment of the entire hydraulic system, the hydraulic hoist cylinder is controlled by the hydraulic system. The piston body in the hydraulic cylinder reciprocates axially on the inner wall, thereby driving the connecting rod and the gate connected to the piston to move linearly to achieve The purpose of opening and closing the gate. Therefore, as the main executive element, the hydraulic cylinder is extremely important for routine maintenance such as replacing seals and cleaning the inner wall of...
