Description

Technical Field

[0001] The invention belongs to the field of power grid maintenance, and in particular relates to an automatic oiling device for a high-tower cable across a river. Background Art

[0002] A river-crossing tower is a special large-span tower, such as the 220kV Huaxiao Line #6 Tower in Nanjing, which is designed as a vertical steel pipe guyed tower and was put into operation in the 1970s. The tower is pulled by eight guy wires in two layers, of which the four guy wires in the lower layer are about 142 meters long each, and the four guy wires in the upper layer are about 201 meters long each. It can be said that these eight guy wires are the lifeline of the tower.

[0003] The 220kV Huaxiao Line #6 tower is located near the river, where the air humidity is high and the operating environment is harsh. According to the corrosion mechanism of the wire metal, the wire will be affected by the temperature, humidity, pollutants, etc., which will cause hole corrosion, gap corrosion, stress corrosion, fatigue corrosion, etc. The operation of the wire will directly affect the stability of the cross-river tower. According to the operation requirements, the wire must be oiled every year. At present, the oiling of the wires of the cross-river towers is generally done manually. Two operators ride on the wire, carrying more than 20 kilograms of oil, and move gradually from top to bottom by physical strength. They must ensure oiling and carry the oil tank. The operation is difficult and physically demanding, and it is urgent to improve the working conditions and improve the working efficiency. Summary of the invention

[0041] Specifically, the oiling unit includes a base 1, an oiling frame 2 and a roller frame.

[0042] A roller frame is provided at the center of the base 1, and rollers are provided on the roller frame. The two rollers are designed according to the angle of the high tower pull line, that is, the connection between the roller and the roller frame is the roller bearing, and the bearing connection line of the two rollers is parallel to the high tower pull line. The front end fixing rod of the roller is connected to the power unit, and the traction of the power unit makes the oiling unit move along the high tower pull line.

[0043] The roller has a groove, and when the oiling unit is installed on the high-tara wire, the high-tara wire is nested in the groove. In addition, a rivet-type safety device is provided at the contact point between the roller and the high-tara wire to prevent tripping during operation.

[0044] A plurality of oiling frames 2 are arranged on both sides of the roller frame. Preferably, the oiling unit of the present invention is a balanced double-body cage, that is, two oiling frames 2 are arranged on both sides of the roller frame. A first oil storage tank 4, an oiling control unit 5 and an oiling tool 6 are arranged in the oiling frame 2 on one side, and an appropriate counterweight is placed in the oiling frame 2 on the other side to maintain balance.

The elbow pipe is set at the nozzle of the oil spray nozzle, and its curvature can be freely adjusted. Before oiling, the staff will adjust it so that the oil spray port is aligned with the high tower pull line.

[0046] The oiling control unit 5 can control the oiling amount per unit time according to the traveling speed of the oiling unit, which is specifically expressed by the following formula:

[0047] Q=k*v

[0048] Wherein k is the injection coefficient, Q is the injection amount per unit time, and v is the travel speed of the oil coating device.

[0049] Preferably, in the present invention, the first oil storage tank 4 adopts an open oil tank; the oiling control unit 5 adopts an electric oil pump, and a ball valve is used to control the oil flow rate; the oiling tool 6 adopts a DSLA145P300 type oil spray nozzle, and a point spray method is used for spraying, and the sprayed oil is evenly attached to the pull wire.

[0050] The power unit includes a traction rope, a diverting pulley and a power assembly 3. One end of the traction rope is connected to the fixed rod in front of the roller, and the other end is connected to the power assembly 3 through a diverting pulley fixed at the top of the high tower pull line.
