Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "both sides" etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.
[0024] The utility model aims to provide a device for adjusting the sag of overhead line conductors in a subsidence area, which can avoid the problems of long sag adjustment time and heavy workload.
[0025] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0026] See also Figure 1 This embodiment provides a device for adjusting the sag of overhead line conductors in a collapse area, which is used to adjust the sag of conductors in overhead lines. The adjusting device includes a protection component 1 and an adjustment component. The adjustment component is used to pass through and fix the conductor passing through the protection component 1. The adjustment component can drive the conductor to move so that the conductor can operate normally.
[0027] It should be noted that the conductor is first passed through the protection component 1 and then fixed to the adjustment component. The protection component 1 plays a protective role to prevent the conductor from slipping during the sag adjustment process. When the sag of the conductor is adjusted, the protection component 1 can be removed.
[0028] Specifically, after the conductor is passed through the protective component 1, it is inserted into the adjusting component. The adjusting component can drive the conductor to move while preventing the conductor from sliding in the opposite direction, so that the sag of the conductor reaches a reasonable range. Then the adjusting component fixes the position of the conductor. With this arrangement, the sag adjustment work can be performed without removing the conductor insulator string, reducing the intensity of the line adjustment work in the collapse area and shortening the line adjustment time, thereby avoiding the problems of long sag adjustment time and heavy workload.
[0029] Preferably, the adjustment assembly includes a strain clamp 2 and a gear assembly, the strain clamp 2 is provided with a wire groove for the wire to pass through, and the gear assembly is used to drive the wire to move along the extension direction of the wire groove.
[0030] It can be understood that the adjustment component includes a strain clamp 2 and a gear assembly. The wire is passed through the strain clamp 2. The gear assembly makes the wire fit tightly into the wire groove of the strain clamp 2. Then the gear assembly drives the wire to move along the extension direction of the wire groove.
[0031] Preferably, the gear assembly includes a ratchet 3, a rocker rod, an active pawl and a non-return pawl, the rocker rod drives the active pawl to move so that the ratchet 3 drives the wire to move, and the non-return pawl can be engaged with the ratchet 3.
[0032] In this embodiment, the gear assembly includes a ratchet 3, a rocker arm, an active pawl and a non-return pawl. The active pawl is in contact with the ratchet 3, and the rocker arm drives the active pawl to move, so that the ratchet 3 rotates in a fixed direction, driving the wire to move. The non-return pawl can be engaged with the ratchet 3 to prevent the ratchet 3 from rotating in a fixed direction. When the wire needs to be adjusted in the opposite direction, it is only necessary to manually lift the non-return pawl, and then drive the ratchet 3 to rotate in the opposite direction to drive the wire to move in the opposite direction. With this arrangement, the size of the sag can be adjusted.
[0033] It should be noted that, the ratchet 3 can be driven to rotate in the opposite direction by adding a rotating member outside the ratchet 3, and the rotating member can be driven to drive the ratchet 3 to rotate.
[0034] Preferably, rotatable fixing members 4 are provided on both sides of the ratchet 3 , and the fixing members 4 are used to fix the conductor and the tension clamp 2 to prevent the conductor from sliding relative to the tension clamp 2 .
[0035] Wherein, rotatable fixing parts 4 are provided on both sides of the ratchet 3. When the sag of the conductor is adjusted to a reasonable range, the fixing parts 4 are used to fasten the conductor and the tension clamp 2 to prevent the conductor and the tension clamp 2 from sliding relative to each other.
[0036] It should be noted that the specific position of the fixing member 4 can be adjusted according to actual conditions as long as the above purpose can be achieved.
[0037] Preferably, there are multiple ratchets 3, adjacent ratchets 3 are connected, and the axes of the ratchets 3 are parallel to each other.
[0038] In this embodiment, there are preferably multiple ratchets 3. Through the mutual transmission of multiple ratchets 3, the force can be amplified, making the sag adjustment more convenient. In addition, the axes of different ratchets 3 are parallel to each other.
[0039] It should be noted that ratchets 3 of different sizes can be selected according to actual conditions, and the specific number or group number of ratchets 3 can be adjusted according to actual conditions, and is not specifically limited here, as long as the above purpose can be achieved.
[0040] Preferably, the protection assembly 1 is fixed by a connecting piece.
[0041] It is understandable that the protection component 1 is fixed by a connector. The fixed protection component 1 can protect the adjustment process of the wire sag and prevent the ratchet 3 from failing to fix the wire. The protection component 1 can play a backup protection role.
[0042] Preferably, the connecting member is a steel wire rope.
[0043] Specifically, the connecting member is preferably a steel wire rope, and the material and model of the connecting member can be adjusted according to actual conditions as long as the above-mentioned purpose can be achieved.
[0044] Preferably, the fixing member 4 is a U-shaped clamp.
[0045] In this embodiment, the fixing member 4 is preferably a U-shaped clamp, and the tightness between the conductor and the tension clamp 2 is achieved by adjusting the U-shaped clamp. Specifically, when the sag needs to be adjusted, the U-shaped clamp is first loosened, and when the sag adjustment is completed, the U-shaped clamp is tightened.
[0046] Preferably, the fixing member 4, the gear assembly and the tension clamp 2 are relatively detachable.
[0047] In this embodiment, the fixing member 4, the gear assembly and the strain clamp 2 are relatively detachable. When any one of the fixing member 4, the gear assembly and the strain clamp 2 is damaged and cannot be used, it can be disassembled and replaced to reduce costs.
[0048] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
