Technical Field
The invention relates to the technical field of deicing robots, in particular to a combined deicing device of a deicing robot for a power transmission line.
Background
The ice and snow cover of the transmission line often cause accidents of tripping, line breaking, pole falling, insulator flashover, communication interruption and the like of the line. Russia, Canada, America, Japan, British, Finland, Iceland and our country all have caused safety accidents due to ice coating of power transmission lines, great economic losses are brought to many countries, and therefore ice and snow disasters become common problems facing power grids of many countries all over the world. China is one of the most serious countries with ice coating on the transmission line, and the probability of the ice damage accident of the transmission line is very high. In the last 30 years, large-area ice disasters happen all over the country, a large amount of icing of lines is the main reason of the accidents, and the manual deicing method is not only low in efficiency, but also greatly threatens the life safety of electric workers. Therefore, it becomes urgent to research a novel deicing method to replace artificial deicing.
When the overhead line deicing robot is used for deicing, the robot moves along the overhead line through the wheel type driving mechanism. In the process, when the robot sensor detects that ice is coated on the front line, the controller starts to start the deicing mechanism to clear the ice coated on the line, and the whole deicing action is finished. The deicing mechanism is required to have the weight as small as possible and be convenient to install, disassemble and maintain on the premise of efficiently removing the ice coated on the overhead line.
The traditional deicing robot uses friction force to walk on a cable clamped by a multipurpose driving wheel, and the walking effect is poor due to the fact that the friction force is reduced after the cable is frozen and frosted, so that the deicing robot capable of walking on the cable stably needs to be designed.

The connection relationship between the first and second jaws 501a and 501b and the sliding and fixing plates 502b and 502a will be described below.
Fig. 8 shows a variation of the second clamping plate 501b being fixed to the wire, the first clamping plate 501a carrying the fixing plate 502a and the device as a whole, moving relative to the second clamping plate 501b and the sliding plate 502 b; partial view B is a structural view of the initial connection of the display clamp 501 to the slide plate 502B, and partial view a is a structural view of the modified connection of the display clamp 501 to the slide plate 502B.
Initially, one end of the first clamping jaw 501a is in the first long groove 502a-1, and one end is at the fourth inflection point 502 b-25; one end of the second clamping jaw 501b is positioned in the second long groove 502b-1, and the other end is positioned at the first inflection point 502 a-23; at this time, the second pusher motor 502b-3 is operated, the first clamping jaw 501a is pushed into the second arc channel 502b-22 from the fourth turning point 502b-25 through the second pushing plate 502b-4, the first clamping jaw 501a is not clamped with the wire, meanwhile, the second clamping jaw 501b enters the first straight channel 502a-21 from the first turning point 502a-23, the second clamping jaw 501b is always clamped with the wire, and then the sliding plate 502b is fixed relative to the wire synchronously with the second clamping jaw 501b in the process that the second clamping jaw 501b moves in the first straight channel 502 a-21.
Meanwhile, during the movement of the first clamping jaw 501a in the second arc channel 502b-22, the fixed plate 502a and thus the whole device are moved relative to the sliding plate 502b and the wire by the structure of the first clamping jaw 501a and the first long groove 502a-1, the first clamping jaw 501a approaches the second clamping jaw 501b until the second clamping jaw 501b is located at the second inflection point 502a-25, and the first clamping jaw 501a is located at the third inflection point 502 b-23.
Next, the first push rod motor 502a-3 is replaced to push the second clamping jaw 501b to operate, the principle is the same as the above, except that the first clamping jaw 501a and the fixing plate 502a are fixed relative to the wire, the sliding plate 502b and the second clamping jaw 501b move relative to the wire, and the second clamping jaw 501b is far away from the first clamping jaw 501 a.
And repeating the above actions to realize the movement of the device on the wire.
It should be noted that before the second jaw 501b moves from the first straight channel 502a-21 to the first curved groove 502a-24, the first jaw 501a has moved from the second curved groove 502b-24 to the third curved groove 502b-23, and the first jaw 501a-1 contacts the cable to clamp the cable, that is, the first jaw 501a-1 and the second jaw 501b-1 clamp the cable at the same time;
at the next moment, the second jaw 501b passes the first curved grooves 502a-24 and reaches the second inflection points 502a-25, the first jaw 501a is at the third inflection point 502b-23 and moves a short distance to the outside, it being noted that the second jaw 501b is always in contact with the wire during this process, and then the second jaw 501b is confined in the second straight groove 502b-21 and remains clamped to the wire.
Preferably, in order to enable the first clamping jaw 501a to move in the second ring-closing groove 502b-2 in a single direction, the second curved groove 502b-24 is provided, and when the first clamping jaw 501a passes the second curved groove 502b-24, reaches the position of the fourth inflection point 502b-25, and moves towards the second curved groove 502b-22, the first clamping jaw cannot return to the second straight groove 502b-21 due to the existence of the second curved groove 502b-24, and only can enter the curved groove 502 b-22.
While at the third inflection point 502b-23 a height difference is provided, in particular that the second arc channel 502b-22 is higher at one end than the second straight channel 502b-21, in order to ensure that at this position the end of the first jaw 501a entering the second straight channel 502b-21 from the second arc channel 502b-22 stays in the second straight channel 502b-21 and remains clamped to the wire, and can again enter the second arc channel 502b-22 from the second straight channel 502b-21 at the fourth inflection point 502b-25 and no longer clamps the wire.
