SU1554063A1 - Trolley for travelling along wires of aerial power transmission line to coat them - Google Patents

Abstract

The invention relates to electric power industry and can be used in trolleys for moving overhead power lines over wires and coating them. The purpose of the invention is to mechanize the movement, expanding the technological capabilities and improving the quality of the coating. The cart has a cradle 2 on which roller hangers 3, 4 are fixed, a brake 5 and a coating chamber 15. The trolley is moved from the electric motor 10, the battery 11 and the console 12. The camera 15 is fixed on the cradle 2 by means of a system of brackets 17, 19, 20 and a shock absorber 18. The chamber 15 is connected to the discharge tank 28 through pipelines 26, 27 wire travel 1 and good quality coating with a viscous liquid that prevents icing or corrosion. 6 Il.

Description

We blocks mounted on a support or 20 into the discharge tank 28. using a lift, lift the trolley. Lever 13 sets the gear down and fastens it to the wire, while the camera 15 is moved to the extreme left position as the trolley moves.

Before the start of the movement of the cart and

the gearbox 9 and the remote control 12 include the engine 10 into the electrical network of the battery 11. The rotational movement 25 of the shaft of the engine 10 through the transmission gear 9, the shaft 8 and 7 of the gearbox 6 singer discharge tank 28. The lever 13 sets the gear

application of the coating device With the help of the device in the pressure tank 28, a pressure is created in the supply system of the viscous fluid into the chamber 15, which by means of the handle 25, the shaft 23, gear 22 and 21 in C-shaped guides the frames 16 are brought to the entrance of the wire 1 through the connector of the jaws. Up to the stop and the wire’s coverage by the oval runners, the brushes 35 and 36. The wires 1 having different diameters enter through

the connector of the parts of the chamber, the slot of which 4o of the joints of the runners-brushes 35 and 36 are coincident with the lower rolling point are raised, the upper part of faces 3 and 4 is lifted along the wire, which creates a camera with a roller 46, and the lower 30 gives a force on the jaws of the lower 30 or lower due to the hinged-movable upper 29 of the chamber 15. When the brackets 17 are connected together and the amorphous pressure on the upper part 29 of the tizator 18 is 45.

the chambers 15 open the springs 32, the chamber opens slightly and as the camera moves further and the wire reaches the oval runners with mi-brushes 36 and 35, the springs 32 press the upper part of the chamber, and the rollers 40 and 41 are pressed to the wire with the help of shock absorbers 47. The last camera part 30 of the camera 15 is disengaged from the wire with the aid of the handle 25. The passage of the trolley through the fastening of the wire to the wire is done in the following way. When the cart approaches the wire attachment to the driver, the engine 10 is turned off. Using valves (not shown) of the discharge tank 28, it overlaps bowing at a certain small angle into the chamber of the fluid and with further mobility of the frame 16 in the hinges by moving the carriage the brackets 17 are dehumidified and are absorbed by means of rollers 40 and the torus 18 and with the further movement of 41, due to the accumulated liquid in the chamber, the spring 32, the bottom of the chamber 30, opens.

The trolley moves along the wire, while the runners 35 and 36 act as guides and clean the wire from dust and dirt. The lower roller 41, which is approximately one-third in the liquid accumulated in the pan, and the upper roller 40, rolling over the wire, compresses it, filling the irregularities and deepening of the multiwire twisted wire with liquid and prevents it from getting moisture and its accumulation in the ground and hollows. When there is a wire on the conduit, the camera 15 is disengaged from the wire with the aid of the handle 25. The passage of the trolley through the fastening of the wire to the wire is done in the following way. When the cart approaches the wire attachment to the driver, the engine 10 is turned off. By means of valves (not shown) of the discharge tank 28 is closed along the 7 15

Rotating the handle 14, the cart is brought to the wire supporting clip (not shown) and with the help of appropriate devices the extreme null (in the direction of movement) roller suspension 4 is folded back and continues to move it until the extreme suspension reaches the clip of the wire attachment girl nde

The front suspension 4 is brought into a vertical position, fixed, and the roller is engaged with the wire.

At the approach of the front driving suspension 3 to the clip of fastening the wires, it is folded back using the appropriate mechanisms. The vertical 8 and horizontal 7 drive shafts with cardan-splined joints, when there is a misalignment between the drive rollers 3, ensure stable kinematic connection with the torque transmission gearbox 6 to the rear drive roller 3. Move the carriage 2 until the front drive suspension 3 moves The clamp for fastening the wire and after the transition is placed in a vertical position 5, is fixed and the suspension roller is engaged with the wire. The trolley continues to move until the rear axle suspension 3 approaches the wire clamp clip, it is folded back and the trolley continues to move with the handle 14 of shaft 7 and the front drive roller 3. When the rear suspension 4 approaches the clamp clip, it folds back, and the cart moves wire mount suspension 4 is installed on the wire as described. Rotating the handle 24, respectively, the shaft 23, moves the camera 15 away from the wire to a distance that ensures unimpeded bypass of the wire. The trolley 2 is moved to the distance of the free-input wire b of the camera connector 15. With the help of the cross-movement mechanism of the camera 15, it is brought to the wire and put into engagement. The necessary conditions are created for the entry of a viscous liquid from the tank 28 into the chambers 15, the lever 13 switches on the corresponding gear and from the console 12 turns on the engine 10. The trolley moves along the wire and from the corresponding uniform
