Description

APPARATUS FOR INSERTING

The present invention relates to a pulling device, for example, which allows a breaker to be quickly and safely pulled into the cradle after periodically checking or repairing the high voltage breaker.

Generally, a high-voltage circuit breaker is a kind of circuit breaker that cuts off the current when an accident such as a load, a short-circuit or the like is opened or closed in transmission, substation or electric circuit.

The high-voltage circuit breaker is connected to the cradle from several to dozens in single layer or multi-layer. In order to carry out the inspection of the mechanical part of such a high-voltage circuit breaker, the high-voltage circuit breaker must be drawn out from the cradle, usually by means of a wheel provided at the lower part of the circuit breaker, along the rail of the cradle or housing.

After the inspection or repair of the high voltage circuit breaker is completed, the circuit breaker must be drawn into the cradle, which is accomplished by the operator directly pulling the circuit breaker toward the cradle.

However, when the breaker is inserted, the terminal of the breaker is inserted into the connection part of the cradle, and there is a high possibility that the electric arc is generated. Particularly, since an operator must directly approach the circuit breaker and draw an electric arc, there is a problem that safety accidents and disasters such as burns are caused by the operator.

The main object of the present invention is to provide a drawing device capable of quickly and safely drawing a breaker to a cradle after periodically checking or repairing a high-voltage breaker, for example.

The drawing device according to an embodiment of the present invention includes: a movable movable carriage; A guide rail standing upright on the moving truck; A platform installed movably along the guide rail; A pushing means mounted on the platform; And a fixing table installed on the platform to provide a supporting force to a housing into which the object is introduced when the pushing means applies a force, the fixing table being fixed to the platform, ; A support member having a bar member inserted into the connection pipe and a pipe member connected at right angles to the longitudinal direction of the bar member; A fixed bar inserted into the pipe member and extending from at least one side so as to be able to extend and retract; And a fixing member for fixing the fixing bar to a desired position in the pipe member.

As described above, according to the present invention, for example, the high-voltage circuit breaker can be quickly and safely drawn into the cradle, so that safety accidents and disasters such as burning of the operator can be prevented, and the facility can be protected .

[ For example, when the pushing means 40 is a fluid pressure cylinder or a hydraulic jack, a pump 43 for applying hydraulic pressure to the operating body may be connected. In the case of an electric solenoid, a power supply unit (not shown) for applying power to the operation body may be connected.

The operation rod 42 is configured such that the extension length thereof can be adjusted, for example, a rod body 421 extending from the operation body 41 in a stretchable manner; A tubular member 422 extending from one end of the rod body; And a push bar 423 extending from the pipe member in a stretchable manner.

The tubular member 422 may also include a fastening member 425 that allows the push bar to be secured in a desired position within the tubular member after it has been stretched. This fixing member can be constructed in the same manner as the fixing member 35 described above.

The push bar 423 includes, at one side thereof, an insertion bar 431 inserted into the tubular member 422; And at least one contact bar 432 connected to the insertion bar on the other side and exerting a force in direct contact with the object 1 to be drawn. The contact bar may be arranged at a uniform interval while being provided in a plurality of such as a three-pointed shape so that the contact bar can stably contact and pressurize the object 1 by dispersing the force.

Each contact bar 432 is also configured such that its extension length can be adjusted, for example, a bar body 436 extending from the insertion bar 431 in a stretchable manner; A ring member 437 mounted on one end of the bar body; And a contact portion 438 extending through the ring member.

The ring member 437 may also include a fastening member 435 that causes the contact portion 438 to extend and be secured to a desired length relative to the post-piercing ring member. This fixing member can be configured similar to the fixing member 35 described above.

An insulating member 439 made of a material such as rubber or plastic may be provided at one end of the contact portion 438 which is in direct contact with the object 1.

Therefore, since the pulling device of the present invention can easily adjust the lengths of the push bar 423 and the contact bar 432 of the pushing means 40, the pushing distance can be adjusted quickly according to the work environment, Shaped contact bar 423 can stably maintain the push.

The platform 30 may further be provided with a fixing table 60 for providing a supporting force to the housing 2 in which the object 1 is drawn in order to support the reaction force when the pushing means 40 applies a force .

The fixing table (60) is fixed to the platform (30) and has a connecting pipe (61) extending parallel to the pushing means (40); (62) having a bar member (621) inserted into the connection pipe at one side and a pipe member (622) connected at a right angle to the longitudinal direction of the bar member at the other side; And a fixing bar 63 inserted into the pipe member 622 of the support portion 62 and extending from at least one side thereof in a stretchable manner.

In addition, the pipe member 622 may include a fixing member 625 that allows the fixing bar 63 to be fixed in a desired position in the pipe member after being stretched. Similarly, the connection tube 61 may include a fixing member 615 that allows the bar member 621 to be secured in a desired position within the connector after it has been stretched. These fixing members may be configured in the same manner as the fixing member 35 described above.

The operation of drawing the circuit breaker to the cradle using the drawing apparatus according to the first embodiment of the present invention constructed as described above will now be described.

In order to draw the breaker, which is the object 1 to be drawn in the upper layer of the housing 2, toward the cradle, the moving carriage 10 is first brought into close contact with the lower portion of the housing.

The lifting means 50 raises the platform 30 on which the push means 40 is mounted to an appropriate height along the guide rails 20 and fixes the elevation position of the platform with the fixing member 35. [

The supporting member 62 or the bar member 621 is extended from the connecting pipe 61 of the fixing table 60 and the extension length thereof is fixed by the fixing member 615. Then, The fixing bar is tightly fixed to the wall surface of the housing 1 while the fixing bar 63 is extended and the length thereof is adjusted, and then the fixing bar 625 fixes the guide rail 20 so that the guide rail 20 does not move.

The pushing bar 423 of the operating rod 42 is extended from the pushing member 40 mounted on the platform 30 and the ring member 437 of the contact bar 432 The length of the contact portion 438 extending from the contact portion 438 is adjusted so that the contact portion is brought into close contact with the surface of the object 1 and then fixed by the respective fixing members 425 and 435 so that the extension length of the operation rod .

Next, by allowing the operator to operate the pump 43 or the power supply device at a safe distance from the breaker, which is the object 1 to be brought in, to drive the pushing means 40, the object can be moved to a desired distance .

When the breaker, which is the object 1 to be drawn, is drawn into the cradle from the lower layer of the housing 2, the height of the platform 30 aligned with the upper layer may be adjusted. In other words, the fixing member 35 of the platform is released and the platform is lowered to a proper height along the guide rail 20 by the elevating means 50, and the lowering position of the platform is fixed by the fixing member.

Thereafter, the breaker can be pulled in the same order as the above-described operation method.
