Description
Technical Field
The invention belongs to the field of a lifting device of a cable well cover for a pumped storage power station.
Background
The cable well lid of using in the pumped storage power station is circular, and the material is cast iron or reinforced concrete for the guard action of cable well avoids the pedestrian to drop into the cable well, and the middle part of cable well lid has the circular shape through-hole, is used for assisting opening of cable well lid, and the below of through-hole is equipped with the pocket of bowl form, and the pocket links to each other with the bottom surface of cable well lid, is used for accepting the debris that drop from the through-hole.
The cable well lid relies on the drag hook of J shape to mention, and the workman catches on the cable well lid with the drag hook during stretching into the through-hole, then mentions the cable well lid, and the cable well way can be opened. Because the cable well lid is mentioned to the drag hook, be the point contact between drag hook and the cable well lid, the easy slope of cable well lid, when the slope of cable well lid was lifted, the focus of cable well lid changed, and the drag hook easily produces on the cable well lid and slides, leads to the drag hook to deviate from the through-hole, and the cable well lid drops, probably pounces workman's foot, and danger is great.
Because a large number of high-voltage cables and a plurality of detection components with high precision are arranged in a cable well of a pumped storage power station, the cable well cover is required to be lifted completely firstly and separated from a cable well port, and then the cable well cover is prevented from being damaged, but the cable well cover cannot be lifted partially and then transversely dragged to be away from the cable well port, so that the situation that sundries fall into the cable well to cause circuit damage and short circuit or damage of the precise components is avoided, but the existing drag hook cannot ensure that the contact point with the cable well cover is located on the gravity center point of the cable well cover, the cable well cover can only be lifted obliquely, the inclination angle sometimes can reach 60 degrees, and workers need to lift the cable well cover to be lifted to a large height to be separated from the cable well port completely, but the cable well cover is heavy, and the labor intensity of the workers is high.
In addition, because the cable well lid drops at the lifting in-process easily, can bring debris such as ground dust or stone into the cable well when dropping, lead to the damaged short circuit of circuit or accurate components and parts in the cable well easily impaired.
Therefore, the existing draw hook used for lifting the cable well lid has the defects of high danger, high labor intensity of workers, broken short circuit of a line and easy damage of components.
Disclosure of Invention

In the cable well cover lifting device, the guide part is of a hollow structure, an upward guide rod is arranged in the guide part, and a guide hole into which the guide rod is inserted is formed in the bottom surface of the switching column.
In the cable well cover lifting device, the switching column is of a hollow structure, and a plurality of inner slotted holes corresponding to the outer slotted holes are formed in the side wall of the switching column.
In the cable well cover lifting device, the handle is linear, and the middle part of the handle is fixed with the connecting rod; the upper end of the shell is provided with an upward-bulging sheet plate, the section of the sheet plate is C-shaped, and the handle is arranged between the sheet plate and the shell; both ends of the plate are provided with downward hanging rings which are C-shaped, both ends of the hanging rings are rotatably connected with the plate through rotating shafts, and the hanging rings are penetrated through handles.
Compared with the prior art, the cable well cover is driven to move upwards by the plurality of support sheets, and the plurality of support sheets form a plane, so that the cable well cover is not easy to incline, the feet of workers cannot be hit due to the inclination of the cable well cover, and the safety is good. And when the support sheets extend out of the shell simultaneously, the support surfaces formed by the support sheets are larger than the through holes of the cable well cover, so that the cable well cover cannot be separated from the cable well cover in the lifting process, and the cable well cover cannot fall off, thereby further ensuring the safety of workers. The cable well cover can be horizontally lifted, so that the cable well cover can be transversely moved and placed on the ground at one side of the cable well opening only by lifting a small height, and the labor intensity of workers is reduced. In addition, because the cable well lid is difficult to drop in the lifting process, sundries such as ground dust or stones are difficult to bring into the cable well, the circuit in the cable well is difficult to damage and short circuit, and precise components and parts are difficult to damage.
Therefore, the cable well cover lifting device has the advantages of small danger, low labor intensity of workers, and difficulty in damaging the circuit and short-circuit components.
