Description

Technical Field

[0001] The invention relates to an insulation coating device, in particular to a bare wire insulation coating device, and belongs to the technical field of insulation transformation of overhead bare wires. Background Art

[0002] As the scale of distribution networks continues to expand, the requirements for stability during operation are becoming increasingly higher. Overhead lines, as an important part of distribution networks, mostly use bare conductors as carriers for power transmission. The service conditions of bare conductors are poor, and there are great safety hazards during operation.

[0003] The existing technology is to achieve insulation transformation by replacing bare wires with insulated wires, but this method consumes a lot of manpower and has a long construction period and low work efficiency.

[0004] The patent with announcement number CN210182144U discloses an electric coating robot for insulating overhead bare conductors. The technical solution of this patent realizes the walking control of the main frame along the overhead bare conductors by driving the rotation of the walking wheels through the walking motor. At the same time, the glue extrusion motor is controlled to drive the rotation of the lead screw push rod to realize glue extrusion. The glue is squeezed from the glue storage tank to the glue inlet of the nozzle mold to coat the bare conductors.

[0005] However, when using the device, the operator still needs to climb up to mount it on the overhead bare wire, and when mounting it, it is also necessary to ensure that the bare wire passes through the glue outlet of the nozzle unit, which brings great inconvenience to the operator's work.

[0060] The third connecting ear 211 and the fourth connecting ear 212 are fixedly connected to the cross beam 210 , and the cross beam 210 is arranged perpendicular to the length direction of the bare wire.

[0082] How it works

[0083] Combination Figures 1 to 8 The working principle of the present invention is described:

[0084] When coating overhead bare conductors, follow the steps below:

[0085] Step 1: The operator mounts the hanging arm 420 onto the bare conductor.

[0086] When the bare conductor is lower to the ground, the operator uses a link rod to mount the hanging arm 420 on the bare conductor; when the bare conductor is higher to the ground, the operator first uses a drone to lift the hanging arm 420 and then mounts it on the bare conductor.

[0087] Step 2: Lift the insulation coating device body

[0088] The operator uses remote control 1 to send a control signal to the PID controller:

[0089] The hoisting motor 111 is started, and the hoisting motor 111 drives the hoisting shaft 112 and the hoisting wheel 113 to rotate, and the sling is wound on the hoisting wheel 113, thereby lifting the insulation coating device body.

[0090] As the insulation coating device body continues to approach the bare wire, the beveled edge of the guide plate 280 can guide the bare wire so that the bare wire accurately abuts against the first coating cavity on the beam 210, until the outer circumferential surface of the walking wheel 411 abuts against the bare wire and the winch motor 111 stops running.

[0091] Step 3: Bare wire positioning

[0092] Since the left wire clamping block 240 and the right wire clamping block 250 are both threadedly connected to the transmission screw 230, when the coating motor 220 is started, the rotation of the transmission screw 230 can drive the left wire clamping block 240 and the right wire clamping block 250 to move closer or farther away synchronously on the beam 210, and the second coating cavity on the left wire clamping block 240 and the third coating cavity on the right wire clamping block 250 gather together to surround the bare wire.

[0093] Step 4: Coating the bare wire

[0094] The feeding motor 320 is started, and the driving gear 330 drives the round nut 340 to rotate, so that the pushing screw 350 and the pushing piston 360 can be fed along the axial direction of the replaceable bottle 103.

[0095] The replaceable material bottle 103 is continuously compressed in the material box 101, and the insulating coating material is continuously transported to the second coating chamber and the third coating chamber through the conveying pipe, and then the insulating coating material is evenly coated on the bare wire.

[0096] The travel motor 430 is started, and the travel motor 430 drives the travel wheel 411 to rotate, and the travel wheel 411 drives the insulation coating device body to move along the length direction of the bare wire, thereby realizing continuous coating along the length direction of the bare wire.

[0097] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
