Description

Technical Field

[0001] The utility model relates to the technical field of insulation coating of transmission lines, in particular to a suspension mechanism of an insulation coating robot used for transmission lines. Background Art

[0002] Transmission lines are a type of power transmission equipment used to transmit electrical energy from power plants to various power consumption locations. Transmission lines can be divided into different types according to factors such as transmission distance and voltage, such as high-voltage transmission lines, ultra-high-voltage transmission lines, etc. They act as a bridge connecting power plants and electricity consumers, and are an indispensable part of modern power systems.

[0003] During the production and maintenance of transmission lines, robots are used to coat the insulation layer. The robot is fixed on the surface of the transmission line by a suspension mechanism, and the insulation layer is coated on the transmission line by moving the suspension mechanism. When a general suspension mechanism moves on the surface of the transmission line, due to the deadweight of the wire and the deadweight of the suspension mechanism, the height of the middle part of the transmission line will be lower than the height at both ends, and the transmission line is not easy to adjust to a horizontal state. When the robot coats the insulation layer on the transmission line, it is difficult to coat the transmission line evenly. When a general suspension mechanism moves on the surface of transmission lines of various specifications, a certain distance is likely to be generated between the suspension mechanism and the transmission line, the transmission device is not easy to fit with the surface of the transmission line, and the suspension mechanism is prone to derailment during movement. In view of the above problems, a suspension mechanism of an insulation coating robot for transmission lines is proposed to solve them. Utility Model Content

[0011] Preferably, a driven pulley is fixedly connected to the front end of the surface of the rotating rod, and the driven pulley is connected to the driving pulley via a transmission belt.

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1-3 As shown, a suspension mechanism of an insulation coating robot for transmission lines includes a suspension box 1, a line passing opening 2 is penetrated through the front lower end of the suspension box 1, a coating device 3 is fixedly installed at the upper center position of the suspension box 1, and the insulation layer of the transmission line can be evenly coated, a transmission motor 4 is fixedly installed at the front right end of the suspension box 1 and above the line passing opening 2, and push rods 5 are fixedly installed at the upper rear end of the suspension box 1 and the left and right sides of the coating device 3 to effectively control the height of the limiting roller 9.

[0020] Slide grooves 6 are penetrated at both ends of the rear side of the suspension box 1, and a slider 7 is slidably connected inside the slide groove 6. The output end of the push rod 5 penetrates the upper end of the slide groove 6 and is fixedly connected to the upper side of the slider 7. The front side of the slider 7 is slidably connected to a sliding rod 8. The front end of the sliding rod 8 is rotatably connected to a limiting roller 9, which can effectively fit the surface of the power transmission line. The rear end of the sliding rod 8 penetrates the front side of the slider 7 and is fixedly connected to a card plate 10. A handle 11 is fixedly connected at the center position of the rear side of the card plate 10 to facilitate control of the horizontal position of the limiting roller 9. A slide plate 12 is fixedly connected to the right side of the card plate 10. The rear side of the suspension box 1 is fixedly connected to the limiting plate 13 with the right side of the slide groove 6. The slide plate 12 is slidably connected to the inside of the limiting plate 13, which effectively prevents the limiting roller 9 from moving laterally.

[0021] The output end of the transmission motor 4 passes through the front side plate of the suspension box 1 and is fixedly connected to a rotating shaft 14, the end of the rotating shaft 14 is fixedly connected to a driving roller 15, a connecting rod 16 is rotatably connected to the rear center position of the driving roller 15, the end of the connecting rod 16 is fixedly connected to the inner wall of the suspension box 1, a driving pulley 17 is fixedly connected to the surface of the rotating shaft 14, a rotating rod 18 is rotatably connected to the left end of the driving roller 15 inside the suspension box 1, a driven roller 19 is fixedly connected to the middle position of the surface of the rotating rod 18, a driven pulley 20 is fixedly connected to the front end of the surface of the rotating rod 18, the driven pulley 20 is connected to the driving pulley 17 through a transmission belt 21, which effectively ensures that the power transmission line between the driving roller 15 and the driven roller 19 remains in a horizontal state.

[0022] Working principle: the upper surface of the transmission line is fitted with the lower surfaces of the driving roller 15 and the driven roller 19 through the wire opening 2, and then the sliding rod 8 is slid forward through the handle 11 to the card plate 10 and abut against the rear side of the slider 7, and the push rod 5 drives the slider 7 to move upward until the lower surface of the transmission line is fitted with the upper surface of the limiting roller 9. During the movement, the slide plate 12 slides inside the limiting plate 13, and the transmission motor 4 drives the driving roller 15 and the driving pulley 17 to rotate. Under the connection of the transmission belt 21, the driven roller 19 and the driven pulley 20 also rotate. Since the two ends of the transmission line are fixed, the suspension box 1 moves on the surface of the transmission line, and the transmission line between the driving roller 15 and the driven roller 19 remains in a relatively horizontal state, and the coating device 3 evenly coats the transmission line that remains in a relatively horizontal state.
