Description

Technical Field

[0001] The present invention relates to the technical field of cable maintenance, and in particular to a mounting device and deicing equipment. Background Art

[0002] During the maintenance of the cable, the cable needs to be handled with the help of a mounting device and a cable processing device. For example, in order to avoid line failures caused by ice coating, relevant deicing means will be used to de-ice. At present, relevant deicing devices have begun to perform de-icing operations on the line. The existing de-icing device generally walks on the ice-covered line, and usually uses the grooved side wall of the walking wheel to achieve the purpose of preventing falling. While walking, the de-icing operation is carried out by carrying a de-icing mechanism, but due to the uneven thickness of the ice layer during the de-icing operation and the wire diameters of the wires before and after the ice layer is broken, they will be inconsistent. In order to prevent the de-icing device from falling due to different wire diameters or easy slipping, the existing technology generally arranges wheels up and down to clamp the wires to form an anti-falling state. In this clamping method, under the action of wind, the line dances, and the mechanical action of the de-icing device is prone to errors, resulting in the clamping being unable to effectively clamp the wire, and it is very easy for the device to detach from the wire and fall quickly. At the same time, this anti-fall method is generally through electric control. In a high-cold environment, it cannot guarantee that the de-icing device can operate normally 100%. It is very likely that the device will crash due to the cold temperature. After a crash occurs, the electric auxiliary wheel will be stuck, and the drone will not be able to remove the equipment autonomously. Manual climbing is required to remove it, which increases the risk.

[0003] Therefore, it is urgent to design a mounting device and deicing equipment to solve the above problems. Summary of the invention

[0016] As an optional solution, the above-mentioned hanging member includes:

[0017] The hook part is hook-shaped;

[0018] The connecting part is rectangular and connected to the hook part. Four first through holes are arranged at four corners of the connecting part. Each of the racks is passed through the first through hole and can be limited by the top of the connecting part.

[0019] As an optional solution, the above-mentioned hanging assembly includes two U-shaped parts, the two U-shaped parts are arranged at intervals in the above-mentioned first direction, the two parallel vertical parts of the above-mentioned U-shaped parts are constructed as the above-mentioned rack, the horizontal part of the above-mentioned U-shaped part can be limited by the top of the above-mentioned connecting part, and the above-mentioned elastic part is connected to the above-mentioned horizontal part.

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] This embodiment provides a mounting device that can avoid using an electric control mechanism to clamp the upper and lower sides of the cable 200, prevent the mounting device from falling, and make the operation more reliable. The mounting device can be used in deicing equipment. Of course, the mounting device can also be used in other functional equipment that operates on the cable 200, which is not limited here.

[0046] like Figure 1-Figure 3As shown, the mounting device includes a hanging component 10, a shell 20, two running wheels 30 and two clamping mechanisms 40. The hanging component 10 includes a hanging member 11 and four racks 123. The bottom of the hanging member 11 is rectangular, and the four corners of the hanging member 11 are respectively connected to the four racks 123, and the top of the hanging member 11 is hook-shaped; the shell 20 is arranged outside the four racks 123, and the shell 20 and the racks 123 are connected by an elastic member 50; the two running wheels 30 are pivotally connected to the two side walls of the shell 20 opposite to each other along a first direction (X direction in the figure), the running wheels 30 are used to be placed on the cable 200, and the cable 200 can be accommodated in the wire groove of the running wheels 30; the two clamping mechanisms 40 are arranged one by one with the running wheels 30, and the clamping mechanism 40 includes a screw 41, two gears 42, a guide member 44 and two clamping components 43, and the screw 41 is arranged along the first direction (X direction in the figure). The guide member 44 is parallel to the lead screw 41 and connected to the housing 20 at both ends. The guide member 44 is parallel to the lead screw 41 and connected to the housing 20 at both ends. The clamping assembly 43 includes a nut 431 and a clamping member 432. The nut 431 is threadedly connected to the lead screw 41 and slidably cooperates with the guide member 44. The clamping member 432 is connected to the nut 431. The clamping member 432 is tilted downward from the end connected to the nut 431 to the free end and toward the other clamping assembly 43. One of the nuts 431 of the two clamping assemblies 43 is threadedly connected to the lead screw 41 in one direction, and the other nut 431 is threadedly connected to the lead screw 41 in the other direction.

[0047] The above-mentioned mounting device is used in conjunction with a drone, and the drone is provided with a ring-shaped member capable of hooking the mounting member 11. Figure 1 In the embodiment, the cable 200 is in a clamping state. When the mounting device needs to be removed, the annular member is put on the mounting member 11, and the drone gradually rises. Figure 1 The state gradually switches to Figure 3The state of the clamping mechanism 40 is not changed. Due to the gravity of the outer shell 20, the running wheel 30 and the clamping mechanism 40, in the initial stage, the running wheel 30 is still tightly attached to the cable 200, and the hanging member 11 moves upward with the four racks 123. At this time, the rack 123 and the corresponding gear 42 produce a transmission relationship, so that the rack 123 drives the corresponding gear 42 to rotate, and the two gears 42 arranged at intervals in the second direction jointly drive the corresponding lead screw 41 to rotate. Due to the sliding fit between the nut 431 and the guide member 44, the two nuts 431 move in opposite directions along the second direction, and the two clamping members 432 gradually move away from each other. When the drone continues to rise and the distance between the hanging assembly 10 and the outer shell 20 reaches the maximum extension distance of the elastic member 50, the running wheel 30 is separated from the cable 200. At this time, the spacing between the two clamping members 432 is large enough and will not hinder the removal of the mounting device. When the drone hanging mounting device is installed on the cable 200, the 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. 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 no electric drive components are involved in the use of the mounting device, thereby avoiding clamping failure. The drone cannot be installed or disassembled alone, and the operator must climb up to operate manually, 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 clamps 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 clamps 432 are cross-arranged and jointly support the cable 200, thereby ensuring that the cable 200 is firmly clamped by the two clamps 432 and the corresponding walking wheels 30.

[0049] Alternatively, if Figure 1 and Figure 2As shown, the hanging member 11 includes a hook portion 111 and a connecting portion 112. The hook portion 111 is hook-shaped and can be hooked to a ring-shaped member on a drone. The connecting portion 112 is rectangular and connected to the hook portion 111. Four first through holes 1121 are provided at the four corners of the connecting portion 112. Each rack 123 is passed through the first through hole 1121 and can be limited by the top of the connecting portion 112. Through the above arrangement, when installing the rack 123, the rack 123 can be inserted into the first through hole 1121, which facilitates the installation of the rack 123.

[0050] In this embodiment, Figure 2 As shown, the hanging assembly 10 includes two U-shaped members 12, which are spaced apart in the first direction, and two parallel vertical portions 121 of the U-shaped member 12 are configured as racks 123. The horizontal portion 122 of the U-shaped member 12 can be limited by the top of the connecting portion 112, and the elastic member 50 is connected to the horizontal portion 122. Through the above arrangement, the two racks 123 are combined into one U-shaped member 12. On the one hand, the number of parts is reduced, and on the other hand, when the height of the connecting portion 112 changes, there will be 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] Alternatively, if Figure 2 As shown, a second protrusion 24 is protruding from the outside of the housing 20, a first protrusion 124 is protruding from the rack 123, and both ends of the elastic member 50 are respectively connected to the first protrusion 124 and the second protrusion 24, thereby realizing an elastic connection between the rack 123 and the housing 20.

[0052] In other embodiments, the four racks 123 may be independent of each other, or the four racks 123 may be directly fixedly connected to the connecting portion 112 , which is not limited here.

[0053] Alternatively, if Figure 2 and Figure 5 As shown, four second through holes 21 are provided at the four corners of the housing 20, and the rack 123 is inserted into the corresponding second through holes 21. The housing 20 also provides a gear accommodating cavity 22 corresponding to each second through hole 21 and communicating with the second through hole 21, and each gear accommodating cavity 22 accommodates a gear 42. Through the above arrangement, the gear 42 is arranged inside the housing 20, and the housing 20 plays a protective role on the gear 42, preventing the gear 42 from easily collecting dust or entering impurities after long-term use, which affects the transmission effect with the rack 123.

[0054] Alternatively, if Figure 1 and Figure 2As shown, the running wheel 30 is pivotally connected to the outer side of the housing 20, and the clamping assembly 43 is located on the inner side of the housing 20. Through the above arrangement, the rack 123 can be more conveniently engaged with the gear 42. At the same time, since the running wheel 30 is relatively large in size, being arranged on the outer side can reduce the design size of the housing 20 and save materials.

[0055] Alternatively, if Figure 1 As shown, the housing 20 has two side walls opposite to each other in the first direction, and the cable 200 can be limited in the limit groove 23. Through the above arrangement, during the rolling process of the walking wheel 30, the limit groove 23 can also limit the cable 200, further preventing the cable 200 from deflecting.

[0056] Furthermore, the two running wheels 30 are respectively pivotally connected to the upper part of the limiting groove 23 , which can ensure that the running wheels 30 are in close contact with the cable 200 .

[0057] Optionally, the opening of the limiting groove 23 is set in an inverted cone shape. It can be understood that the limiting groove 23 is composed of a connected rectangular groove 231 and a conical groove 232. When placing the mounting device, the conical groove 232 can guide the cable 200 into the rectangular groove 231, thereby reducing the operating accuracy requirements of the drone. The rectangular groove 231 plays the role of limiting the cable 200.

[0058] This embodiment also provides a deicing device, including a deicing device and the above-mentioned mounting device, the deicing device is connected to the mounting device and is used to remove ice on the cable 200. Among them, there are many forms of deicing devices in the prior art, and those skilled in the art can flexibly select according to the situation, which will not be described here. By adopting the above-mentioned mounting device, the deicing device is safer when working at high altitude.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
