Specific implementation process:

1. Measure the distance of 1m and mark it. The operator climbs the pole to a suitable place and uses an insulating distance measuring pole to measure the distance 1 meter from the lowermost cross arm to make a mark.

2. Install the isolation baffle. The operator installs the insulating baffle at the mark. Before lifting, the operator should bind the isolation baffle to ensure a firm fixation, and the insulating baffle and the rod body are in a state of 90 degrees.

3. Install the switch hanger. The operator installs the support hanger under the insulating baffle. All parts of the operator's body should not exceed the isolation baffle. Before lifting, the operator should bind the support hanger to ensure a firm fixation. The installation position of the support hanger and the bracket position of the switch on the column parallel.

4. Install pulleys and ropes. The operator passes the insulating sling through the two fixed pulleys, and fixes the first section of the insulating sling to the foremost section of the hoisting point (that is, the front end of the support hanger) through the U-ring, and fixes the anchor pulley to the vertical of the hoisting point. Below, pull out the movable pulley from the upper section of the insulating hanging rope, fix the integrally installed column switch 4 and the fixed bracket with an insulated non-polar rope, and lead out the hanging point, hang the hanging point on the moving pulley, at the appropriate position of the column switch Tie another insulated wind rope.

5. Install the switch. After the switch on the lifting column is just off the ground, the person in charge of the work should check whether the force on all parties is even, and conduct an impact test. After confirming that it is correct, the lifting can be continued. The operator uses a motorized grinder with pulleys or manual lifting, and a special person is installed for lifting. Unified command, when the lifting object is slightly off the ground, check again whether the force of all parties is even and carry out the impact test to maintain the balance. During the lifting process, the lifting object must not lose the protection of the wind rope. During the hoisting process, always use the wind rope to protect the switch and keep it at a sufficient distance from the tower equipment to avoid damage to the switch. After the switch is lifted to a suitable position, adjust the direction of the switch and fix the switch. The ground operator should tighten the sling to prevent it from slipping off suddenly during the lifting switch. All parts of the operator's body shall not exceed the isolation baffle. When the operator moves and works on the pole, he must correctly use the safety belt and the secondary safety rope, and hang it in a reliable place. The secondary safety rope should be used high and low. The foot buckle should be adjusted at any time according to the rod diameter to prevent it from falling off.

6. Remove the switch support hanger. All parts of the operator's body should not exceed the isolation baffle. After the switch support hanger is removed, the operator should bind the switch support hanger to ensure a firm fixation. Barriers should be installed below the high-altitude operation, and no one should pass or stay below the operation point.

7. Remove the insulating isolation baffle. All parts of the operator's body shall not exceed the marked line 1m below the cross arm. After the insulating isolation baffle is removed, the operator should bind the insulating isolation baffle to ensure a firm fixation. Barriers should be installed below the work at heights, and no one is allowed to pass or stay below the work point.
