The technical scheme of the invention is as follows:
a method for installing a cable bushing comprises the following steps:
firstly, preparing a guide rope, arranging a movable pulley at the bottom end of the guide rope, and integrally forming a hanging device;
secondly, when the cable bushing is installed, firstly winding a hanging strip on the cable bushing, then hooking the end part of the hanging strip on a crane hook, then hooking a guide rope of a hanging device on the crane hook, starting a crane, and simultaneously hanging the hanging device and the cable bushing;
thirdly, when the cable penetrating sleeve is hung above the assembling frame, an operator on the crown block selects a bolt matched with the cable joint, the bolt is tightly bound by a rope, the tightly bound bolt bypasses the movable pulley slideway, then the bolt penetrates into the cable penetrating sleeve, the bolt is continuously lowered until the bolt penetrates out of the cable penetrating sleeve, and then the bolt is screwed at a bolt hole of the cable joint connected with the end part of the cable;
starting the crown block, transferring the cable penetrating sleeve to the mounting position on the assembling frame, pulling the rope upwards by an operator on the crown block, penetrating the cable penetrating sleeve along with the rope to complete the installation of the cable penetrating sleeve, and taking down the hanging device after the installation.
The rope is a white cloth belt or a nylon rope.
And fourthly, when the cable penetrating sleeve is placed to the installation position on the assembly frame in the fourth step, an operator needs to confirm whether the cable penetrating sleeve is in a vertical state or not, and if the cable penetrating sleeve is not in the vertical state, the angle of the hanging strip is adjusted by both hands to ensure that the cable penetrating sleeve is in the vertical state.
The invention has the following positive effects: the cable head is simple and convenient to operate, saves cost, can be repeatedly used, is not easy to fall off when the cable head penetrates into the cable penetrating sleeve, and can be well penetrated out.

Detailed Description
The invention is further described with reference to the following figures and examples:
a method for installing a cable bushing comprises the following steps:
firstly, preparing a guide rope 3, arranging a movable pulley 4 at the bottom end of the guide rope 3, and integrally forming a hanging device;
secondly, when the cable bushing 5 is installed, firstly winding a hanging strip 2 on the cable bushing 5, then hooking the end part of the hanging strip on a crane hook 1, then hooking a guide rope 3 of a hanging device on the crane hook 1, starting a crane, and simultaneously hanging the hanging device and the cable bushing;
thirdly, when the cable penetrating sleeve 5 is hung above the assembling frame, an operator on the crown block 8 selects a bolt 9 matched with the cable joint 6, tightly ties the bolt by a rope 10, winds the tightly tied bolt 9 around a slide way of the movable pulley 4, then penetrates into the cable penetrating sleeve 5, continues to put down the bolt 9 until the bolt 9 penetrates out of the cable penetrating sleeve 5, and then screws the bolt 9 at a bolt hole of the cable joint 6 connected with the end part of the cable 7;
