Description
BACKGROUND OF THE
Generally, electric power of about 20,000V from the power plant is boosted to ultra high voltage to be transmitted to the first substation to be suitable for transmission. Then, electricity transmitted to the first substation is stepped down to about 22.9kV and supplied to the second substation or each customer. The electricity supplied from the secondary substation is supplied to the receiving facilities of each customer through the distribution system consisting of the imaginary distribution line and the underground distribution line, and electricity is supplied through the special high pressure customer, the high pressure customer, and various outdoor installation transformers. It is supplied to the supplied low-pressure consumer.
Especially, due to the increase in population and buildings, urban distribution lines are becoming more and more underground. As the number of electricity users increases and the usage of electricity becomes more complicated, special high voltage cable connection boxes for underground wiring lines are installed at individual places .
In such a high-voltage cable connection box for the underground wiring line, it was required to insert or connect the elbow connection member in a live state to the connection portion.
Conventionally, an operator fixes an elbow joint at the end of an insulation stick and inserts or separates the elbow joint into a connection portion of a cable connection box. However, not only is it not possible to ensure safety in a live wire state, It is not possible to surely perform the inputting or separating operation, so that the working efficiency and the operation reliability are poor.
Of course, the 'Elbow connection active wire opening / closing device' used when replacing the transformer is disclosed in the patent registration Nos. 10-824584 and 10-842321, and the elbow connection material can be turned on or off by a remote control However, this is a large and complicated mechanical device, which is not a simple device for the worker to work on, and it is not only expensive, but also can not be used for replacing elbow joints of cable connection boxes installed on the ground there was.
SUMMARY OF THE INVENTION The present invention has been made in order to solve all of the problems of the prior art described above, and it is an object of the present invention to provide a hand- And it can be reliably inserted into or disconnected from the connection portion of the cable connection box, thereby providing excellent work safety and operational reliability.
An object of the present invention is to provide an excellent workability because the operation and insertion and disconnection of the elbow joint by shrinkage and expansion of the impact spring are performed automatically or semiautomatically.
The present invention is characterized in that the insulation guider is insulated and supported by a cable connection box and an insulation guider, and the insulation guider is fastened to the cable connection box by hooks so that the worker does not directly receive the impact even when the elbow connection member is inserted and separated, The purpose is to provide.
The present invention relates to a pawl type body, power means provided at the rear of the body, forward / backward movement operation means installed inside the body and operated by power means, A holder means for engaging or disengaging the elbow connection member to or from the connecting portion of the cable connection case and holding or releasing the elbow connection member; and an insulating guider connected to the front of the body and connected and supported in an insulated state to the cable connection case, Feature.
According to the present invention, the power means is constituted by a motor.
The back and forth moving operation means includes a rotating screw that is rotated forward and backward by a power means, a forward and backward operation nut that is spirally coupled to the forward and backward positions of the rotating screw and moves back and forth by forward and backward rotation of the rotating screw A front and rear latch piston inserted into the front and rear interlocking nuts so as to be opposed to each other and moving forward and rearward and having an inclined portion on the front side facing each other and a stepped groove portion on the rear side on the outer side; A latch slide pipe inserted into the outer side of the impact spring to move back and forth and form a groove in the longitudinal direction of the inner side and a longitudinal hole formed in the body at the inner side of the slide pipe to lock or unlock the front and rear latch pistons, A front and rear support balls connected to the holder means and a front and rear lug piston The guider of the front latch piston is engaged with the guide groove at the time of insertion and the guider of the rear latch piston is engaged with the guide groove at the time of detachment to move the holder means back and forth. .
The front and rear interlocking nuts move back and forth within a range in which the guide protrusions are guided by the first and second elongated holes formed in the longitudinal direction of the body. When the elbow joint is inserted and separated, the guide protrusion pushes the latch slide pipe, And the piston is operated to release the lock.
The back and forth moving operation means includes a rotating screw that is rotated forward and backward by a power means, a forward and backward operation nut that is spirally coupled to the forward and backward positions of the rotating screw and moves back and forth by forward and backward rotation of the rotating screw An impact spring inserted between the front and rear latch pistons, an impact spring disposed on an upper portion of the body, and an impact spring inserted between the front and rear latch pistons, The front and rear latch cushions for locking and unlocking the front and rear latch pistons are provided on both sides of the spring, and a shaft pin connected to the body and the latch spring is provided on the upper and lower long holes to rotate the upper and lower latches. The guider of the front and rear latch pistons is inserted and guided in the guide groove of the rear side, and when the guider is inserted, the guider of the front latch piston is guided in the guide groove And the guiding groove of the rear latch piston is engaged with the guide groove to move the holder means back and forth when the rim is operated and separated.
The holder means includes a frame fixed to the front and rear working rod ends, left and right holders provided on the left and right front sides of the frame for pivotally holding or gripping the elbow connecting member, And the operation pin is constituted by an operation pin which presses the rear portion of the left and right holders while rotating back and forth by the drive portion that transmits the rotational force of the drive motor and rotates left and right.
A holding plate is provided at the rear of the holder means, and a moving shaft having a magnet which is brought into contact with the holding plate by magnetic force at the front side and a stopper at the rear side is inserted into a guide hole of a connecting bracket connected to the rear of the insulating guider, It is characterized in that the holder is prevented from being jammed together with the forward movement of the holder means at a predetermined interval at the initial stage of the insertion of the connection member.
According to the present invention, the insulation guider has a feature that a hook that can be fixed to a cable connection box is coupled to a front side of the insulation guider, and the hook is screwed to the front of the insulation guider to adjust the position of the hook to move back and forth .
The insulating guider of the present invention is characterized in that a long hole is formed in the front and rear longitudinal direction so that the guide protrusion of the holder means is guided to move back and forth.
The present invention is a pole type so that it is easy to carry the operator and the holder means for holding the elbow joint is reliably inserted into or separated from the connecting portion of the cable connection case by the contraction and expansion of the impact spring of the back and forth moving means, And work reliability.
In addition, since the impact spring inflates and deflates, the elbow joint member is inserted and separated automatically or semiautomatically, resulting in an excellent workability.
Further, since the insulating guider is fixed to the cable connection box by the hooks, the worker is not directly influenced by the impact of the input and separation process of the elbow connection material, Effect.
