Problems solved by technology

[0002] The robot inspection method generally uses the guide (ground) wire as the moving track of the robot. Due to the principle of thermal expansion and cold contraction, the transmission wire will periodically have a certain arc, and will swing under the action of the wind. The inspection robot and its The matching suspension running device will accelerate the swing when moving on the wire due to its large mass, and the safety is poor; Greatly reduce the detection accuracy of the inspection; at present, there is an urgent need for a light-weight, self-deflection and energy-saving wire inspection equipment on the market

Embodiment 1

[0030] see Figure 1-3 , an energy-saving suspension device for a transmission line tension type inspection robot, comprising a suspension frame 1, a turntable 2 is arranged in the middle of the suspension frame 1, the rotation axis of the turntable 2 is vertically distributed, the suspension frame 1 is a groove structure and its A support frame 11 is provided on the top, and the support frame 11 is elastically slid up and down to be connected with vertically distributed support columns 3. Preferably, the support frame 11 is provided with a guide hole 111 that is slidably matched with the support column 3, and the outer wall of the support column 3 And near the top, a baffle plate 31 is fixedly arranged, and the support column 3 is sleeved with a return spring 9 between the baffle plate 31 and the support frame 11; the support column 3 is located on the top of the turntable 2, and the top of the support column 3 is provided with In the middle sheave 4, the suspension frame 1 i...

Embodiment 2

[0032] see Figure 4 with Figure 5 The difference from Embodiment 1 is that one end of the support sleeve 611 is swingably connected to the vertical plate 61, the swing axis of the support sleeve 611 is vertically distributed and the swing angle range is 15-25 degrees, and a hinge can be set on one side of the vertical plate 61 One end of the hinge seat and the support sleeve 611 is rotationally connected, and the hinge base is provided with limit plates located on both sides of the support sleeve 611. The two limit plates are used to limit the swing range of the support sleeve 611. During the high-speed rotation of the turntable 2 Among them, the axis of rotation of the roller 7 is deflected relative to the radial direction of the turntable 2. At this time, the roller 7 has a tendency to move outward when rolling along the inner wall of the conical cover 8, that is to say, it has a tendency to climb outward. Thus, the rolling plate 7 can push the support column 3 to rise, a...

Abstract

The invention discloses a power transmission line tensioning type inspection robot energy-saving suspension device, which comprises a suspension frame. A rotary table is arranged in the middle of the suspension frame, the rotation axis of the rotary table is vertically distributed, the suspension frame is of a groove-shaped structure, and a supporting frame is arranged on the suspension frame. According to the invention, an up-and-down moving support column is arranged in the middle of the suspension frame, a middle grooved wheel is arranged at the top of the support column, a conical cover is arranged at the bottom of the support column, the rotary table is arranged at the lower part of the conical cover on the suspension frame, a guide plate is radially and slidably connected to the peripheral wall of the rotary table, a vertical plate is arranged on the guide plate, a support sleeve is arranged on one side of the vertical plate, the support sleeve is rotationally connected with a rolling disc, the outer edge of the rolling disc makes contact with the inner conical face of a conical sleeve, when the rotary table rotates at a high speed, the rolling disc can move outwards under the action of centrifugal force and roll along the inner wall of the conical sleeve, and therefore the conical sleeve can be indirectly pushed to move upwards, the middle grooved wheel jacks up a wire upwards to tension the wire, the swing amplitude of the wire is reduced, and the safety level is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission line inspection, in particular to an energy-saving suspension device for a power transmission line tension type inspection robot. Background technique [0002] The robot inspection method generally uses the guide (ground) wire as the robot’s traveling track. Due to the principle of thermal expansion and cold contraction, the power transmission wire will periodically have a certain arc, and will swing under the action of the wind. The inspection robot and its The matching suspension running device will accelerate the swing when moving on the wire due to its large mass, and the safety is poor; The detection accuracy of the inspection is greatly reduced; at present, there is an urgent need for a light-weight, self-deflection and energy-saving wire inspection equipment on the market. [0003] Therefore, the present invention provides an energy-saving suspension device for a power transmiss...
