The cross beam 1 may be a long body with any cross section shape, for example, the cross section may be an angle shape, a rectangle shape, an H shape, a W shape, etc., the length of the cross beam 1 may be set according to practical needs, and the embodiment of the present invention is not limited specifically. It should be noted that the hoisting part 11 needs to be arranged in the middle of the beam 1 and needs to be located in the middle of the two locking parts 2, so as to ensure that the hoisting tension is applied to the middle of the beam 1 during hoisting, and further the tension can be evenly distributed to the locking parts 2 located at the two ends of the beam 1, so that the stress of the composite insulator string lifted by the two locking parts 2 is even. The sling 11 may be of any construction that facilitates the attachment of a rope, such as a through hole, a sling or a hook.

The locking parts 2 provided at both ends of the beam 1 may be end parts located at both ends of the beam 1, or may be both ends located at one side surface of the beam 1. The first locking body 21 and the second locking body 22 of the locking part 2 may be identical in structure, may be in the form of blocks, and are provided with the above-mentioned circular arc-shaped recesses on opposite sides for subsequent machining and maintenance by replacement. The locking through hole 3 formed by the first locking body 21 and the second locking body 22 needs to be matched with an end fitting of the composite insulator string, the composite insulator string is locked by clamping the end fitting, and the detachable connection between the first locking body 21 and the second locking body 22 can be realized through the connection of the bolt 5.

The self-locking hook is a structure that the self-locking piece is clamped by the hook body, and the lifting part 11 is arranged as the self-locking hook according to the technology known by technical personnel in the field, so that the self-locking hook can be conveniently connected with a steel wire rope, has the self-locking function, can avoid the hook body from being separated from the steel wire rope, and is safer to use.

Further, the self-locking hook can be rotatably connected with the middle part of the cross beam 1.

Specifically, the beam 1 and the self-locking hook can be connected through a rotating shaft, so that the self-locking hook can rotate 360 degrees relative to the beam 1, and the angle of the hoisted duplex insulator string can be adjusted conveniently during hoisting operation.

In the specific implementation, the beam 1 is mainly an angular profile, and a plurality of reinforcing ribs 4 are arranged at intervals inside the corners of the angular profile.
