Description

Technical Field

[0001] The utility model relates to the technical field of electric power transmission, in particular to a wire clamp for solving the problem of inclination of a double-split conductor insulator string in a goaf area. Background Art

[0002] Double-split conductor is a special type of conductor, which is usually used in ultra-high voltage transmission lines. This conductor adopts splitting technology, so that the conductor of each phase is split into two, and each branch conductor is composed of a conductor with a smaller diameter. The branch conductors are spaced a certain distance apart and arranged in a symmetrical polygon. This conductor structure can effectively suppress corona discharge and reduce line reactance, thereby improving transmission efficiency. The suspension clamp is mainly used to fix the conductor on the insulator string of the straight pole tower, or to suspend the lightning conductor on the straight pole tower. In addition, it is also widely used on transposition pole towers and fixed on the jumper of the tension angle pole tower. According to the use requirements, the suspension clamps on the market are mainly divided into two types: old-fashioned ship-shaped clamps and pre-twisted suspension clamps.

[0003] The normal working state of the insulator string is vertical downward, and the straight pole tower is only subjected to vertical load. Affected by the ground collapse in the goaf, the displacement of the conductor will drive the vertical insulator string to produce an inclined displacement. The inclined insulator string pulls on the crossarm, generating a lateral load, and the pole tower is subjected to force and produces deflection. For this reason, the inclined insulator string and the displaced suspension wire clamp need to be reset in time. However, the friction between the existing wire clamp and the conductor is large, which makes it impossible for the insulator string to be reset automatically. Manual reset of the insulator string is required, causing workers to work at high altitude for a long time. At the same time, the existing wire clamp is affected by friction during the wire pulling process, which can easily cause the wire skin to be damaged during the wire pulling process. At the same time, the wire pulling length of the wire cannot be measured, which is inconvenient to use. Utility Model Content

[0004] The utility model provides a wire clamp for solving the problem of inclination of double-split conductor insulator strings in goaf areas, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A wire clamp for solving the problem of inclination of double-split conductor insulator strings in goaf areas comprises a fixing mechanism, and is characterized in that wire clamp mechanisms are arranged at both ends of the fixing mechanism, and a measuring mechanism is fixedly connected to one side of the surface of the wire clamp mechanism.

[0007] A further improvement of the technical solution of the utility model is that the fixing mechanism comprises a fixing piece, surfaces of both ends of the fixing piece are overlapped with mounting pieces, and a fixing bolt is inserted into the interior of the mounting piece close to one end of the fixing piece.

[0008] A further improvement of the technical solution of the utility model is that: the surface of the first fixing bolt overlaps with the two ends of the fixing member, and the second fixing bolt is inserted into the interior of the installation member away from the end of the fixing member.

[0009] A further improvement of the technical solution of the utility model is that the wire clamp mechanism includes a clamping hull, the interior of the clamping hull is fixedly connected to a fixing rod, the interior of the middle part of the clamping hull overlaps with the surface of a fixing bolt, and the surface of the clamping hull overlaps with a side of the mounting part away from the fixing part.

[0010] A further improvement of the technical solution of the utility model is that a bearing is sleeved on the surface of the fixed rod, a pulley is fixedly connected to the surface of the bearing, oil seals are provided at both ends of the bearing, and a magnetic part is fixedly connected to one end of the pulley.

[0011] A further improvement of the technical solution of the utility model is that the measuring mechanism includes a mounting plate, one side of the mounting plate overlaps with one side of the clamping hull, the internal thread of the mounting plate is connected with a fixing screw, and one end of the fixing screw is connected with the internal thread of the clamping hull.

[0012] A further improvement of the technical solution of the utility model is that a magnetic induction counter is fixedly connected to a side of the mounting plate away from the clamping hull, and a wire is plugged into the top of the magnetic induction counter.

[0013] A further improvement of the technical solution of the utility model is that: the end of the wire away from the magnetic induction counter is fixedly connected with an induction member, and the surface of the induction member is plugged into a side of the clamping hull close to the mounting plate.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] The utility model provides a wire clamp for solving the problem of tilting of an insulator string of a double-split conductor in a goaf area. Through the arrangement of the wire clamp mechanism, when pulling the wire, through the arrangement of a bearing and a pulley, the sliding friction between a conventional wire clamp and the wire is changed into rolling friction, thereby reducing the friction between the wire clamp and the wire, avoiding damage to the wire skin caused by large friction. At the same time, the friction between the wire clamp and the wire is small, so that the insulator string can be automatically reset after tilting, reducing the working time of workers at high altitudes, making it more convenient to use. The arrangement of the measuring mechanism can calculate the number of rotations of the pulley through a magnetic induction counter during the wire pulling process, thereby calculating the length of the pulled wire, making it more convenient to use.

[0024] like Figure 1-5 As shown, the utility model provides a wire clamp for solving the problem of tilting of double-split conductor insulator strings in goaf areas, including a fixing mechanism 1, wire clamp mechanisms 2 are arranged at both ends of the fixing mechanism 1, a measuring mechanism 3 is fixedly connected to one side of the surface of the wire clamp mechanism 2, the fixing mechanism 1 includes a fixing piece 11, surfaces of both ends of the fixing piece 11 are overlapped with mounting pieces 12, a fixing bolt 13 is inserted into the interior of the mounting piece 12 close to one end of the fixing piece 11, a surface of the fixing bolt 13 is overlapped with both ends of the fixing piece 11, and a fixing bolt 2 14 is inserted into the interior of the mounting piece 12 away from one end of the fixing piece 11.

[0025] In this embodiment, during the process of pulling the wire, under the action of the friction between the wire and the pulley 24, the bearing 23 drives the pulley 24 to rotate, so that the sliding friction between the conventional wire clamp and the wire is converted into rolling friction, thereby reducing the friction between the wire and the wire clamp and preventing the wire from being damaged during the process of pulling the wire.

[0026] Example 2

[0027] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the wire clamp mechanism 2 includes a clamping hull 21, the interior of the clamping hull 21 is fixedly connected to a fixing rod 22, the interior of the middle part of the clamping hull 21 overlaps with the surface of the fixing bolt 13, the surface of the clamping hull 21 overlaps with the side of the mounting part 12 away from the fixing part 11, the surface of the fixing rod 22 is sleeved with a bearing 23, the surface of the bearing 23 is fixedly connected to a pulley 24, oil seals 25 are provided at both ends of the bearing 23, and one end of the pulley 24 is fixedly connected to a magnetic part 26.

[0028] In this embodiment, when the wire is pulled, the pulley 24 drives the magnetic part 26 to rotate. Under the action of the induction part 35, the rotation state of the magnetic part 26 is detected and counted by the magnetic induction counter 33. After calculation based on the count, the length of the pulling wire can be accurately obtained, and then the pulling force can be calculated, making it more convenient to use.

[0029] Example 3

[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the measuring mechanism 3 includes a mounting plate 31, one side of the mounting plate 31 is overlapped with one side of the clamping hull 21, the internal thread of the mounting plate 31 is connected with a fixing screw 32, one end of the fixing screw 32 is connected with the internal thread of the clamping hull 21, and a magnetic induction counter 33 is fixedly connected to the side of the mounting plate 31 away from the clamping hull 21, a wire 34 is plugged into the top of the magnetic induction counter 33, and an end of the wire 34 away from the magnetic induction counter 33 is fixedly connected to a sensing member 35, and a surface of the sensing member 35 is plugged into the side of the clamping hull 21 close to the mounting plate 31.

[0031] In this embodiment, the sliding friction between the conventional wire clamp and the conductor is converted into rolling friction, thereby reducing the friction between the conductor and the wire clamp. When the insulator is tilted, it can be automatically reset without manual reset, which shortens the workers' high-altitude working time and reduces the risk of falling from heights.

[0032] The working principle of the wire clamp for solving the problem of tilted insulator string of double split conductor in goaf area will be described in detail below.

At the same time, when the wire is pulled, the pulley 24 drives the magnetic part 26 to rotate. Under the action of the induction part 35, the rotation state of the magnetic part 26 is detected and counted by the magnetic induction counter 33. After calculation based on the count, the length of the wire pulling can be accurately obtained, and then the pulling force can be calculated, making it easier to use. At the same time, the friction between the wire and the wire clamp is reduced. When the insulator is tilted, it can be automatically reset without manual reset, which shortens the workers' high-altitude working time and reduces the risk of falling from high altitude.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
