Description

TECHNICAL FIELD

[0002] In the process of maintaining the cable, the treatment of the cable needs to be assisted by the mounting device and the treatment device of the cable to be used together. For example, in order to avoid the failure of the line caused by icing, the relevant deicing means is used to remove the ice. At present, the related deicing device has begun to deice on the line. The existing deicing device generally walks on the line covered with ice, and generally uses the groove-shaped side wall of the walking wheel to achieve the purpose of preventing falling. While walking, the deicing mechanism is carried out to deice, but due to the uneven thickness of the ice layer and the inconsistent wire diameter before and after the broken ice layer during the deicing operation. In order to prevent the deicing device from falling due to the inconsistency of the wire diameter or the phenomenon of easy slipping, the existing technology generally arranges the wheels up and down to clamp the wire to form a state of preventing falling. This clamping method, under the action of the wind, the line dancing, plus the mechanical action of the deicing device, is easy to produce error, leading to clamping cannot effectively clamp the wire, very easy to make the device from the wire, fall rapidly. At the same time, this anti-falling method is generally controlled by electricity, which cannot guarantee that the deicing device can normally operate in a high-cold environment.

[0047] The above mounting device is used in cooperation with a unmanned aerial vehicle, the unmanned aerial vehicle is provided with a ring-shaped piece capable of hooking the hanging piece 11, Figure 1 The cable 200 is in a clamped state, when it is needed to take down the mounting device, the ring-shaped piece is sleeved on the hanging piece 11, the unmanned aerial vehicle gradually rises, Figure 1 from the state gradually switches to Figure 3When the yoke 10 is in a state of being moved upwards, the two gears 42 are driven by the gears 433 and 434, respectively, and the two gears 42 are driven by the gears 434. When the yoke 10 is in a state of being moved upwards, the two gears 42 are driven by the gears 433 and 434, respectively, and the two gears 42 are driven by the gears 433 and 434, respectively. Figure 3 The state gradually switches to Figure 1 In the state, and under the action of the elastic force of the elastic member 50, the hanging assembly 10 descends more smoothly during the descent of the drone. During this process, the two clamping members 432 approach each other, and the final state is shown in FIG. Figure 4 The two clamping members 432 cross and abut the lower part of the cable 200, and the corresponding walking wheels 30 abut the upper side of the cable 200, ensuring that the cable 200 is clamped. Under the action of wind, the mounting device will not fall off, and the mounting device does not involve any electric drive components during use, avoiding clamping failure, and the situation where the drone cannot be installed or disassembled alone and the operator must climb up and operate manually occurs, which makes the operation safer.

[0048] It is understood that the hanging assembly 10 has a raised position away from the housing 20 ( Figure 3 ) and a placement position close to the housing 20 ( Figure 1 ), when in the raised position, the mounting device is separated from the cable 200, and the two clamping members 432 are spaced apart in the second direction to allow the cable 200 to pass through, thereby ensuring that the drone removes the mounting device from the cable 200; when in the placed position, the mounting device is placed on the cable 200, and the two clamping members 432 are cross-arranged and jointly support the cable 200, thereby ensuring that the cable 200 is firmly clamped by the two clamping members 432 and the corresponding walking wheels 30.

[0049] Alternatively, as Figure 1 and Figure 2As shown, the hanging part 11 comprises a hook part 111 and a connecting part 112, the hook part 111 is hook-shaped and can be hooked on the ring-shaped part on the unmanned aerial vehicle; the connecting part 112 is rectangular and connected with the hook part 111, four first through holes 1121 are arranged at the four corners of the connecting part 112, and each rack 123 is arranged in the first through hole 1121 and can be limited by the top of the connecting part 112. Through the above arrangement, when the rack 123 is installed, the rack 123 can be inserted into the first through hole 1121, which facilitates the installation of the rack 123.

[0050] In this embodiment, as shown in the figure, Figure 2 The hanging assembly 10 comprises two U-shaped parts 12, which are arranged in the first direction and parallel to each other. The two vertical parts 121 of the U-shaped part 12 are configured as the rack 123, the horizontal part 122 of the U-shaped part 12 is limited by the top of the connecting part 112, and the elastic part 50 is connected with the horizontal part 122. Through the above arrangement, two racks 123 are combined into one U-shaped part 12, on the one hand, the number of parts is reduced, on the other hand, when the height of the connecting part 112 changes, there is a slight difference in height between the two corners. The above arrangement ensures the synchronous movement of the two racks 123 connected to the same lead screw 41, thereby ensuring the force balance at both ends of the lead screw 41.

[0051] Optionally, as shown in the figure, Figure 2 The outer part of the shell 20 protrudes a second protruding part 24, the rack 123 protrudes a first protruding part 124, and the two ends of the elastic part 50 are connected with the first protruding part 124 and the second protruding part 24 respectively, thereby realizing the elastic connection of the rack 123 and the shell 20.

[0052] In other embodiments, the four racks 123 can also be independent, or the four racks 123 can be directly fixed with the connecting part 112, which is not limited here.

[0053] Optionally, as shown in the figure, Figure 2 and Figure 5 The four corners of the shell 20 are provided with four second through holes 21, the rack 123 is arranged in the corresponding second through hole 21, and the shell 20 is also provided with a gear accommodating cavity 22 corresponding to each second through hole 21, and a gear 42 is arranged in each gear accommodating cavity 22. Through the above arrangement, the gear 42 is arranged in the interior of the shell 20, and the shell 20 protects the gear 42, preventing dust from accumulating on the gear 42 or impurities from entering and affecting the transmission effect of the rack 123 after a long time of use.

[0054] Optionally, as shown in the figure, Figure 1 and Figure 2As shown, the walking wheels 30 are pivoted to the outer side of the housing 20, and the clamping assembly 43 is located at the inner side of the housing 20. Through the above arrangement, the rack 123 can be engaged with the gear 42 more conveniently, and meanwhile, due to the large size of the walking wheels 30, the design size of the housing 20 can be reduced by arranging the walking wheels 30 at the outer side, thereby saving materials.

[0055] Optionally, as shown, the housing 20 is provided with a limiting groove 23 at two opposite side walls in the first direction, and the cable 200 can be limited in the limiting groove 23. Through the above arrangement, during the rolling of the walking wheels 30, the limiting groove 23 can also limit the cable 200, thereby further preventing the cable 200 from deviating. Figure 1

[0056] Further, the two walking wheels 30 are respectively pivoted above the limiting grooves 23, which can ensure that the walking wheels 30 are in close contact with the cable 200.

[0057] Optionally, the opening of the limiting groove 23 is arranged in an inverted conical shape. It can be understood that the limiting groove 23 is composed of a rectangular groove 231 and a conical groove 232 which are connected in communication. When the hanging device is placed, the conical groove 232 can guide the cable 200 into the rectangular groove 231, thereby reducing the operation precision requirement of the unmanned aerial vehicle. The rectangular groove 231 functions to limit the cable 200.

[0058] The embodiment also provides an ice removing device, which comprises the ice removing device and the above hanging device. The ice removing device is connected with the hanging device and is used for removing the ice on the cable 200. The ice removing device has various forms in the prior art, and the person skilled in the art can select flexibly according to the situation, and thus no further description is given here. The ice removing device adopts the above hanging device, and thus the safety is higher during the aerial work.
