In the prior art, application No.: 201922093979.2, discloses an auxiliary tool for replacing porcelain cross arm, which comprises a fastener, a bracket, a top plate and a jack; wherein, need pass through the staple bolt with the support and connect on the shaft tower when using, the jack is installed on the roof and is used for supporting the wire for the problem of porcelain cross arm change has been solved.

The technical problems that arise from this are: (1) when the jack supports the cable, the cable needs to be placed in a wire slot on a jack supporting block, the cable is arranged in the wire slot in a penetrating manner, and locking bolts are arranged on two opposite sides of the supporting block above the cable; the supporting block and the wire groove are arranged, so that the cable is fixed on the jack; because the high-voltage line is heavy, the operation is difficult in the process of taking out the cable from the supporting block, and a lot of operation risks are brought to the work of erecting the high-altitude cable. (2) When the jack is required to support the cable, the jack needs to be fixed on the tower through the bracket and the hoop, and the hoop type fixing operation method needs to surround the tower and then lock and fix the tower; in the high-altitude operation, the mode is relatively troublesome and labor-consuming, and further increases the operation risk.

How to reduce the operation risk of erecting the cable in the process of erecting the cable at high altitude is a problem to be solved urgently by the personnel in the field.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an erect supplementary transition device of high-voltage line for solve the problem of mentioning among the above-mentioned background art.

The technical method comprises the following steps: the tower is provided with a cross arm, the cross arm is provided with an insulating bottle and a skyward slide, and the skyward slide is provided with a lock catch connected with a hinge; the method specifically comprises the following steps: a lifting device is further arranged on a cross arm between the upward sliding part and the insulating bottle, and the lifting device has the functions of supporting cables and adjusting the height up and down;

wherein, lifting device is equipped with screw rod structure and the elevation structure who is connected with the screw rod, and lifting device accessible rotation thread's mode carries out altitude mixture control lifting device top is fixed and is equipped with the line frame, the line frame has the structure that middle low both sides face extends to outside level, be the wire casing in the middle of the line frame, the cable can be supported to the wire casing size, the wire casing direction is perpendicular with the cross arm direction, the hasp is put up the frame with a side that closes on the line frame under the open mode and is connected.

Further, the fixed joint structure that is equipped with in lifting devices bottom, the joint structure can just block on the cross arm, the structural locking bolt that is equipped with of joint, can with through screwing up locking bolt lifting devices fixes on the cross arm.

Further, the joint structure is "C" type, joint structure top fixed connection lifting devices, be the bayonet socket in the middle of the joint structure, can block on the cross arm, joint structure bottom is equipped with locking bolt.

Further, the raceway is sized to accommodate 240 square cables.

Further, the lifting device can be adjusted in height in a manual mode or an electric mode.

Further, the lifting device is a jack.

The utility model has the advantages that: when a high-voltage wire is erected, the skyward sliding lock catch is opened and then erected on one side face of an adjacent wire rack, the lock catch inclines towards the lifting device, the wire cable slides upwards from the skyward sliding lock catch and is taken out, the wire cable slides into the wire slot from the lock catch position, and after the height of the lifting device is adjusted, the wire cable is finally placed on the insulating bottle. Through the setting of lifting device for originally, slide to carrying between the insulating bottle from the sky and carry the work to change into: the cable slides from the upward direction to the position between the lifting devices to push and slide, and part of work of lifting the cable is converted into completion by the lifting devices; the reduction carries the working strength of cable, is favorable to saving operating personnel physical stamina and improves the control to high altitude construction, reduces the dangerous accident simultaneously and takes place, and it plays fine transition effect between smooth and the insulating bottle towards the sky.

The jack bottom is equipped with "C" type joint structure, and accessible joint structure bayonet socket blocks the jack on the cross arm, can fix the jack on the cross arm through the locking bolt that joint structure bottom set up, and simple structure easily masters makes things convenient for the dismouting of jack, reduces the high altitude construction degree of difficulty and risk.
