Abstract
The utility model discloses a seal oiling device, which comprises a base and an oil storage tank which is screwed on the base, wherein, a seal rubber pad is arranged between the base and the oil storage tank; an oil filling hole communicated with an inner chamber is formed on the base; a ring gasket is arranged in the inner chamber of the base; an oil inlet groove is lengthways formed on the outerwall of the ring gasket; a piston is arranged in the oil storage tank; and a piston push rod is arranged at the lower part of the piston. The seal oiling device is arranged at the lower part of an operating handle of a three-stage linkage isolating switch, and is screwed on the handle of the three-stage linkage isolating switch through a bolt in a bolt fixing hole formed on the base. A rotating shaft and a bearing of the operating handle of the three-stage linkage isolating switch are arranged inside the seal oiling device. The seal oiling device has the advantages of simple structure, good sealing effect, flexile operation and convenient use, and can keep the long-term lubrication state of the operating handle of the three-stage linkage isolating switch.
Description
Technical field
The utility model relates to a kind of electric power maintenance equipment, is specifically related to a kind of sealing oiling device that is used on three utmost points interlock isolating switch.
Background technology
In electric power system, three utmost points interlock isolating switch is to be applied on the high voltage overhead power circuit, can have a power failure, send electric high-voltage switch gear to arbitrary section supply line or equipment.It has the isolated fault section, recovers the effect of normal power supply rapidly, to guarantee the needs of productive life electricity consumption.Convenient simultaneously arbitrary power supply section is safeguarded and managed.But because three utmost points interlock isolating switch generally is installed on the outdoor electric pole, can't carry out regular lubricated, be affected by the external environment, the easy corrosion of three utmost points interlock isolator operation handle, can not draw away and cause to operate a switch, the drawing clamping stagnation problem of closing a floodgate and not closing can not be isolated fault section rapidly, very likely cause major accident, cause the tremendous economic loss.
The utility model content
The purpose of this utility model provides a kind of three utmost points interlock isolator operation that makes and seals oiling device flexibly.
For achieving the above object, the utility model sealing oiling device, comprise pedestal and with the oil storage cylinder of pedestal bolt, between pedestal and the oil storage cylinder sealing rubber pad is set; Have an oil filler point that communicates with inner chamber on the pedestal, the pedestal inner chamber is provided with ring washer, vertically is provided with the oil-feed groove along the ring washer outer wall, and piston is set in the oil storage cylinder, and the piston below is provided with a piston pushing ram.
Described piston is provided with lower plate, and the piston pushing ram is fixed on the lower plate of piston, and with the fixed head bolt of oil storage cylinder.
The utility model sealing oiling device is arranged on three utmost points interlock isolator operation handle below, and this apparatus structure is simple, and good sealing effect can make three utmost points interlock isolator operation handle keep long-term lubricating status, and flexible operation is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model sealing oiling device and three utmost points interlock isolator operation handle;
Fig. 2 and Fig. 3 are respectively the front view and the vertical views of the utility model ring washer.
Embodiment
As shown in Figure 1, the sealing oiling device comprises pedestal 1 and oil storage cylinder 4, sealing rubber pad 2 is set, pedestal and oil storage cylinder bolt between pedestal and the oil storage cylinder.The outer wall of pedestal vertically is provided with at least three bolt holes.Have an oil filler point that communicates with inner chamber 8 on the pedestal, the pedestal inner chamber is provided with a ring washer 3, shown in Fig. 2,3, vertically be provided with a plurality of oil-feed grooves 7 along the ring washer outer wall, piston 5 is set in the oil storage cylinder, piston is provided with lower plate, and set bolt pushing ram 6 on the lower plate 10, pushing ram are provided with bolt plate 9 bolts of screw thread and oil storage cylinder below.
The rotating shaft 12 of the operating grip of three utmost points interlock isolating switch is arranged in the ring washer of oiling device pedestal inner chamber, rotating shaft is provided with bearing 15, and handle 11 bolts by bolt in the bolt hole on the pedestal and three utmost points interlock isolating switch, be provided with rubber sheet gasket 14 between pedestal and the handle, rotating shaft is provided with the rotating spanner 13 of control three utmost points interlock isolating switch closure.
During work, inject antifreezing oil by oil filler point 8 to oil storage cylinder inside, make the oil storage cylinder inner chamber be full of fluid, under the situation that the oil filler point sealing bolt is tightened, the piston propeller is slowly boosted, oil storage cylinder is inner, and its inner space is proportional to be dwindled because the angle of rake propelling of piston makes, while is owing to the space dwindling, make lubricating oil along upwards rising in the gap of the bearing of operating grip and axle sleeve, slowly advance along with piston is angle of rake, the space dwindles, and lubricating oil is finally along the end face of overflow operation mechanism handle bearing between the slit of mechanism's bearing and axle sleeve, and at this moment the piston propeller just rests on this normal pressure position and remains unchanged.Make operating grip bearing and shaft room be full of fluid, because the piston propeller in the rigid body is to rest on the pressure position that this overflows fluid, so the fluid of mechanism's bearing and shaft room can not descend, all the time rest on the position that bearing and shaft room overflow, finally make operating mechanism keep lubricated for a long time.
Claims (2)
