Description

Technical Field

[0001] The present invention relates to the technical field of cable clamping, and in particular to a clamping structure and an extension bracket. Background Art

[0002] In high-voltage transmission lines ranging from 35kV to 220kV, the stability and safety of tension towers are crucial. However, when encountering extreme weather, such as natural disasters such as lightning strikes, the insulators on the line may be severely damaged or even completely shattered. In this case, the conductors near the insulators may suffer serious strand breakage due to the lack of sufficient insulation protection. During emergency repairs, construction workers often need to ride out of the insulators and the outside of the conductors to carry out wire hanging operations in order to repair or replace damaged insulators and conductors. This operation itself is extremely risky, because working on damaged conductors may cause further breakage of the conductors if not done carefully. Once the conductor breaks, not only will the equipment fall, but the lives of the construction workers will also be seriously threatened, resulting in major safety accidents. Therefore, for the maintenance and repair of such high-voltage transmission lines, strict safety measures must be taken to ensure the safety of construction workers and minimize the impact on power supply.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 , which is the first embodiment of the present invention, provides a clamping structure, including an isolation plate 100, a first boss 101 provided on the outer wall of the isolation plate 100, a rotating disk 102 provided on the outer wall of the isolation plate 100, and a clamping plate 103 connected to one end of the rotating disk 102 close to the first boss 101.

[0034] The isolation plate 100 is a flat plate, on the surface of which a first boss 101 is fixedly mounted, forming a protruding table top on the surface of the isolation plate 100; the surface of the isolation plate close to the first boss 101 is rotatably connected to a rotating disk 102, and one end of the rotating disk 103 close to the first boss 101 is rotatably connected to a clamping plate 103, and the point where the clamping plate 103 is rotatably connected to the rotating disk 102 and the point where the rotating disk 103 rotates form an arc motion trajectory. When the rotating disk 102 is pulled, the point where the clamping plate 103 is rotatably connected to the rotating disk 102 will slowly approach the first boss 101, thereby shortening the distance between the clamping plate 103 and the first boss 101. The process of continuously shortening the distance between the clamping plate 103 and the first boss 101 is utilized to realize the function of clamping wires of different radii.

[0035] In summary, when in use, the wire is placed in the space between the clamping plate 103 and the first boss 101, and then the rotating disk 102 is pulled away from one end of the clamping plate 103, so that the clamping plate 103 is constantly approaching the first boss 101. When the surface of the clamping plate 103 close to the first boss 101 contacts the wire, the wire will contact the surface of the first boss 101, and then a resistance state is formed on the clamping plate 103, and the clamping plate 103 is restricted from rotating. At the same time, the resistance force is transmitted to the rotating disk 102, restricting the rotation of the rotating disk 102, thereby clamping the wire. In order to prevent the clamping structure from loosening, the rotating disk 102 is pulled to the maximum extent, and then the end of the rotating disk 102 away from the clamping plate 103 is connected to the limiting structure of the prior art, such as a micro electric hoist, bolt fixing, etc. to limit the rotation of the rotating disk 102, to ensure that the rotating disk 102 does not rotate, and to ensure the stability of the wire clamping.

[0036] Example 2

[0037] Reference Figures 1 to 6 , which is the second embodiment of the present invention, includes a rotating disk 102 including a first end 102a and a second end 102b, and the line connecting the first end 102a and the second end 102b to the rotating point of the rotating disk 102 is not a straight line; the first end 102a is rotatably connected to the clamping plate 103, and the second end 102b is rotatably connected to the pull rod 104.

[0038] Among them, the rotating disk 102 is composed of a circular disk and two round ears, the two round ears are respectively the first end 102a and the second end 102b, and there is a certain angle between the two round ears. The advantage of this design is that when the point where the clamping plate 103 rotates with the rotating disk 102 and the line connecting the rotation point of the rotating disk 102 are perpendicular to the surface of the first boss 101, the second end 102b and the first end 102a will not form a straight line, so that pulling does not require a pulling force perpendicular to the second end 102b, which is more convenient for operators to pull and allows operators to operate with less effort; a pull rod 104 is rotatably connected to the second end 102b, and the rotation of the pull rod 104 is more convenient for operators to operate, and is also suitable for operators to adjust the pulling angle, so that operators can adjust to a comfortable adjustment angle.

[0039] The isolation plate 100 includes a first support frame 100 a , and the first support frame 100 a includes a first through hole 100 a - 1 for the pull rod 104 to slide.

[0040] Among them, a first support frame 100a extends from the side wall of the isolation plate 100, and the pull rod 104 is passed through the first through hole 100a-1. The advantage of this design is that the pull rod 104 can slide along the track of the first through hole 100a-1 when the angle between the first end 102a and the second end 102b is fixed, so that the operator can directly pull the pull rod 104 in a comfortable manner, making the pulling process more labor-saving.

[0041] The outer wall of the isolation plate 100 is provided with a first rotating shaft 105 for the rotating disk 102 to rotate, and the outer wall of the first rotating shaft 105 is rotatably provided with a rotating gear 201 .

[0042] In this solution, the isolation plate 100 extends a first rotating shaft 105 on the surface of the first boss 101, the rotating disk 102 rotates on the outer wall of the first rotating shaft 105, and a rotating gear 201 is fixedly installed on the outer wall of the first rotating shaft 105. When the transmission disk 102 is pulled, the rotating gear 201 will not be driven to rotate.

[0043] The first end 102 a is connected to the clamping plate 103 by means of a second rotating shaft 106 , and the outer wall of the second rotating shaft 106 is rotatably connected to a driven disk 202 , and the outer wall of the driven disk 202 abuts against the closing plate 203 .

[0044] The driven plate 202 includes a curved surface 202 a and half teeth 202 b meshing with the rotating gear 201 .

[0045] The first end 102a is connected to the clamping plate 103 by means of the second rotating shaft 106, so as to realize the rotation connection between the first end 102 and the clamping plate 103; and a driven disk 202 is rotationally connected to the outer surface of the second rotating shaft 106, and a surface of the driven disk 202 close to the rotating gear 201 is provided with a half tooth 202b, and there are a plurality of half teeth 202b arrays, and the half teeth 202b are meshedly connected with the transmission gear 201, and the other half of the outer surface of the driven disk 202 is padded to form a curved surface, that is, from one end of the half teeth 202b, the radius of the driven disk 202 is continuously increased until the other end The advantage of this design is that when the second end 102b of the rotating disk 102 is pulled, the first end 101a of the rotating disk 102 will drive the clamping plate 103 to rotate around the first rotating shaft 105, and then the driven disk 202 will roll along the surface of the rotating gear 201, and then the driven disk 202 will approach the surface of the clamping plate 103 to push the closing plate 102 close to the first boss 101. While clamping the wire, the gap between the clamping plate 103 and the first boss 101 is covered by the closing plate 102, thereby preventing the wire from slipping during the clamping process.

[0046] The outer wall of the closing plate 203 is connected with a slide bar 203a, and the outer wall of the clamping plate 103 is provided with a movable channel 103a for the slide bar 203a to slide;

[0047] A limiting plate 203a - 1 is disposed on the outer wall of the slide bar 203a , and a first elastic member 204 is disposed between the limiting plate 203a - 1 and the outer wall of the movable channel 103a .

[0048] Among them, a sliding rod 203a is fixedly connected to the surface of the closing plate 203 close to the driven disk 202, the sliding rod 203a passes through the active channel 103a and abuts against the surface of the curved surface 202a, and the limiting plate 203a-1 is above the active channel 103a; a first elastic member 204 is installed between the upper surface of the active channel 103a and the limiting plate 203a-1 on the outer surface of the sliding rod 203a, and the first elastic member 204 is sleeved on the outer wall of the sliding rod 203a; the first elastic member 204 is a structure that can be deformed and reset, such as a spring, an airbag and other structures, and this scheme uses a compression spring.

[0049] The surface of the clamping plate 103 close to the first boss 101 is serrated.

[0050] The surface of the clamping plate 103 close to the wire is serrated to increase the holding force on the wire.

[0051] In summary, when in use, the operator can use the existing technology of retractable structure, such as screw, telescopic motor, etc., to fix the clamping structure with the telescopic structure, and then send the clamping structure to a distant place, and then put the wire between the clamping plate 103 and the first boss 101 by observation, and then pull the pull rod 104 to make the clamping plate 103 and the first boss 101 clamp the wire, and at the same time, the closing plate 203 synchronously closes the gap between the clamping plate 103 and the first boss 101.

[0052] Example 3

[0053] Reference Figures 1 to 8 , which is the third embodiment of the present invention, in order to solve the possible high-altitude operation and facilitate the carrying of the telescopic structure, this embodiment further provides an extension bracket, including a mounting head 301 and an extension rod 302 arranged at one end of the mounting head 301 .

[0054] A threaded tube 301a is provided at one end of the mounting head 301, a threaded head 302a capable of being threadedly connected to the threaded tube 301a is provided at one end of the extension rod 302, and a threaded tube 301a is provided at one end of the extension rod 302 away from the threaded tube 301a.

[0055] In this solution, the mounting head 301 is fixedly mounted on the first rotating shaft 105 in the clamping structure, and in this solution the first rotating shaft 105 is rotatably connected to the isolation plate 100, and the two are connected by friction, that is, in the absence of external force, the two will not rotate; a threaded tube 301a is installed at one end of the mounting head 301, and a threaded head 302a is installed at one end of the extension rod 302, and the threaded head 302a and the threaded tube 301a may be screwed together, that is, the extension rod 302 can be connected to the mounting head 301, and the other end of the extension rod 302 can continue to be screwed together with another extension rod 302, so as to meet the problem of the extended length. At the same time, due to the longer extended length, the pull rod 104 may be inconvenient to operate, and a rope may be connected to one end of the pull rod 104 to facilitate the subsequent direct pulling of the railing for operation.

[0056] The advantage of this design scheme is that the operator can adjust the length of the extension rod 302 according to the length, and then hold the extension rod 302 to send the clamping structure to the appropriate position, and then pull the rope to drive the pull rod 104 to rotate, and then clamp the cable; at the same time, our structure can also be directly disassembled from a distance. After use, since the clamping structure has a clamping force on the wire, and the wire has the same reaction force on the clamping structure, the isolation plate 100 will not rotate at this time. It is only necessary to rotate the extension rod 302 to drive the first rotating shaft 105 to rotate, and the rotating gear 201 will drive the driven disk 202 to rotate, and then the sliding rod 203a on the outer wall of the closing plate 203 will slide along the curved surface 203b under the action of the first elastic member 204, and then it will open.
