It is a new type of transmission line that uses SF6 gas or other mixed gases as the insulating medium, and the outer shell and conductor are arranged coaxially. The GIL is equipped with a GIL cylinder on the outside. During installation, two GIL cylinders need to be docked. Since the standard length of the GIL cylinder is generally 12 to 18 meters, the current method is generally to use two cranes to hoist the same GIL cylinder, and adjust the horizontal angle, pitch angle and front and rear position through the cooperation of the two cranes. However, it is limited by the complexity and diversity of the on-site installation environment, such as mountainous areas, where cranes cannot be stationed and construction operations cannot be carried out. At the same time, it takes a long time and is costly to use a crane for hoisting and docking, and the crane has low adjustment accuracy and is inconvenient to operate.

The lifting motor 24 has a flat rotating head that can be inserted into and fit into the right end of the bracket threaded rod 17. The rotating hole block 27 is welded on the other side of the support seat platform 26. The rotating hole block 27 is an iron block with a hole and a built-in bearing, which provides a fulcrum for the rotation of the bracket threaded rod 17. The left end of the bracket threaded rod 17 is inserted into the rotating hole block 27.

[0043] A straight through hole 30 and a threaded hole 31 are respectively provided on the bottom fixed rod 19 of the X-shaped bracket and the bottom movable rod 21 of the X-shaped bracket.

[0046] When the lifting motor 24 rotates, the lifting motor 24 drives the bracket threaded rod 17 to rotate, so that the threaded hole 31 drives the bottom movable rod 21 of the X-shaped bracket to move, and then drives the X-shaped bracket active rod 15 to move, that is, the X-shaped bracket is extended and retracted, so that the table top of the spinning mechanism platform 25 rises or falls.

[0047] like Figure 1 and Figure 7 As shown, the driving wheel mechanism includes a traveling wheel motor 32 and a wheel unit, and the wheel unit includes a driving gear 33, a transmission gear 34, a wheel 35, a housing 36, a driving shaft 37 and a follower shaft 38.

[0051] When the GIL installation auxiliary device provided by the present invention is used to dock the GIL cylinder, the head and tail of the GIL cylinder to be docked need to be placed in the U-shaped groove of the corresponding GIL installation auxiliary device respectively, the height of the GIL cylinder is adjusted by the lifting mechanism of the device, and the position of the flange bolt hole at the GIL cylinder interface is adjusted by clockwise and counterclockwise movement of the U-shaped groove, so as to accurately and efficiently achieve the docking of the GIL cylinder. The specific working principle is as follows:

[0052] 1) In the initial state, after the GIL cylinder is placed in the U-shaped slot, the threaded rod of the bracket is driven to rotate by the lifting motor. The X-shaped bracket is designed to have both the upper and lower parts fixed at one end, and the other end uses a movable rod to adapt to the rotation of the threaded rod of the bracket to achieve the lifting of the X-shaped bracket, thereby adjusting the height of the GIL cylinder.

[0053] 2) When the device is adjusted to the corresponding height, the U-shaped slot can be driven by the U-shaped slot rotating motor to rotate clockwise or counterclockwise, thereby adjusting the horizontal docking angle of the GIL cylinder to facilitate the docking of the GIL cylinder flange.

[0054] 3) The U-shaped slot has a limited protection system formed by the slot limit unit and the stroke limit unit. When the U-shaped slot reaches the limit position, the motor will be powered off; if there is a power outage at the work site, the horizontal docking angle of the GIL cylinder can also be manually adjusted through the hand-crank device.

[0055] 4) The device can be driven forward or backward by the motor.
