Detailed ways

Below in conjunction with embodiment the invention is described in further detail.

Example 1:

As shown in Figure 1-2, the invention of this example is a hanging basket used for helicopter live maintenance operations, and the hanging basket is arranged under the helicopter through ropes; the hanging basket includes a movable platform 5 and is arranged on the movable platform 5 below the non-slip bottom plate 6; the movable platform 5 is provided with a hanger for connecting ropes, a tool box 2 for placing tools and a wire support 3 for placing wires.

The movable platform 5 is a cuboid constructed by round pipes; two cross-connected round pipes are arranged on the diagonal of each side of the movable platform 5 .

The hanging parts are lifting lugs 1; the lifting lugs 1 are arranged on the four corners above the movable platform 5.

The toolbox 2 is formed by bending sheet metal parts, and is hung on the round tube above the movable platform 5 of the hanging basket through an elastic hook; Triangular prism.

The bottoms of the four sides of the movable platform 5 are provided with baffles 4 perpendicular to the anti-slip bottom plate 6 .

The pilot controls the helicopter to hover at the live maintenance operation place, and the live maintenance operator stands directly in the gondola, and applies relevant live work tools to carry out the live maintenance work. Such as replacement of the ground wire anti-vibration hammer, pre-twisted wire repair of live wires and replacement of spacer rods, etc. The live working process of the hanging basket is:

(1) Pre-flight inspection

① Fuel requirement inspection, inspection of ancillary equipment and fast equipment installations, hazard identification; work ticket, dangerous point control sheet and flight release sheet signed.

② Check the appearance of tools and protective equipment on the ground to see if they are in good condition; check the insulation resistance of insulating tools.

③ After checking the double name of the line, the number of the tower, and the phase sequence, the staff conducts the impact test and inspection of the safety tools before work, and checks that the surrounding environment of the tower, the helicopter insulation sling and the connection point of the hanging basket are intact.

(2) take off

The helicopter takes off from the front of the office building of the training base. It should take off smoothly to prevent the hanging basket from floating in the air; observe the power of the helicopter while circling.

(3) Personnel close to the live body inspection

The live operator identifies navigational obstacles, identifies and confirms the number of the operating tower, and the helicopter slowly descends from a height of 30 meters above the conductor to approach the conductor; Adjust the flight attitude.

(4) The hanging basket enters the equipotential

When the hanging basket is 10-15 meters away from the working position, the live operator in the hanging basket guides the pilot to descend the helicopter through the three-way communication equipment and flying gestures, and at the same time instructs the pilot to control the descending speed of the helicopter—slow/fast and the approach angle of the helicopter—high/low, Left/Right; During the descent, the pilot and the line operator communicate the speed and angle of the helicopter’s descent at all times. After the line operator reaches the target position, after ensuring that the gondola is reliably connected to the wire, remove the connection between the gondola and the sling. Connect, and notify the pilot to fly the helicopter away.

(5) Start live maintenance work

The live working personnel start the maintenance work item by item according to the relevant requirements and steps of the operation process card, and remove the old spacer after installing a new spacer near the old spacer. Complete the replacement of the wire spacer.

During the maintenance process, the ground crew, the line operator and the pilot must keep the communication unblocked at all times. Online operators should keep the ground staff informed of work progress and personal safety status.

(6) The hanging platform and live workers leave the equipotential

After the operator completes the maintenance, he will inform the personnel on the helicopter and the ground command personnel through the three-way communication device. After the aircraft arrives, hovers and descends, the sling is slowly put into the working position, and the live operator connects and fixes the sling to the gondola, and informs the pilot to take off. The pilot can leave only after getting the take-off confirmation, and slowly ascends, and returns to the field after the gondola breaks away from the wire.

During the flight, live working personnel should take their own fixed protective measures.

(7) Landing

When the gondola is about to land, the ground crew should guide the gondola into the ground bracket in time as the helicopter descends, and at the same time, pay attention to prevent the sling from being entangled with the helicopter rotor after being blown up.

The ground crew takes out the old spacer rods in the hanging basket and puts them into the pre-twisted wires. Repeat steps (2)-(7) to complete the pre-twisted wire repair wire operation.

When the gondola is about to land, the ground crew should guide the gondola into the ground bracket in time as the helicopter descends.

The ground crew puts the repair pipe into the gondola. Repeat steps (2)-(7) to complete the operation of repairing the repairing pipe and repairing the wire.

(8) Clean up the site

Check the use of inspection tools. The operators clean up the tools and utensils and pack them into bags (boxes), so that the work is completed, the materials are cleaned, and the site is cleaned up. After the sling is retracted, put it in the box in time to prevent the sling from getting wet. Put the hanging basket into the ground bracket, fix it securely, and transport it back with a transport vehicle.

Please refer to Appendix 6 for the live working instructions of the helicopter hanging basket method.

See Appendix 7 for the live working process card of the helicopter hanging basket method.

See Appendix 8 for the on-site operation procedures of each support specialty for flight operations.

3. Meteorological conditions

Work should be carried out in good weather. In case of lightning (hearing thunder, seeing lightning), rain and fog, etc., live work is not allowed; if the wind force is greater than level 5 (10m/s) or the humidity is greater than 80%, live work is not suitable.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Those of ordinary skill in the art should understand with reference to the above embodiments that the specific implementation methods of the present invention can still be modified or equivalent. Replacement, any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the protection scope of the claims of the present invention pending application.
