Description
Technical Field
The utility model belongs to electric power fortune dimension field, concretely relates to general type tangent tower circuit overhauls cross arm hanging point device.
Background
In the line maintenance work of a 500KV linear wine glass tower, a cross arm hanging point system needs to be temporarily installed on angle steel during maintenance work because a fixing device is not arranged on cross arm steel of a tower head.
Two methods are currently used, one is a steel wire rope winding method as shown in fig. 1, two sleepers A are used for compacting angle steel B, and then a steel rope C is wound and wrapped to form a hanging point system. However, because the types of tower materials are various, the angle steel is often not matched with the sleeper, the sleeper cannot completely wrap the angle steel, the steel rope sleeve and the angle steel have sharp shearing angles, stress concentration is caused, the phenomenon that a single steel wire is broken is easy to occur, and due to the winding form, the abrasion is caused after long-term use, the angle steel is broken due to overlarge stress in the process of replacing the insulator, and potential safety hazards exist. And when the steel rope sleeve is not scrapped due to the existence of less than the safe broken wire number, the steel rope sleeve is inconvenient to carry and easily scratches the skin of a worker. In addition, the steel rope sleeve has elasticity, and the winding is labor-consuming during working; when the material is prepared, the length of the steel rope sleeve cannot be adjusted, and the on-site work is directly influenced when the steel rope sleeve is selected to be too long or too short. The other method is a long U-shaped ring method as shown in fig. 2, a lengthened U-shaped ring D is matched with a clamping piece E, and for a cross arm with a single fixed width, the method is superior to a steel wire rope winding method, but the method has poor adaptability, and the phenomena of side-to-side sliding, jumping and co-vibration are generated in the overhauling process, so that great potential safety hazards exist.
Disclosure of Invention
The utility model aims at there is the shearing force in original operation method wire rope cover and angle steel, because long-term the use causes deformation and wearing and tearing, can cause inconvenience to the use, still can be at the in-process of changing the insulator because the atress is too big and the fracture has certain potential safety hazard. When the steel rope sleeve is not scrapped due to the fact that the number of the broken steel wires is lower than the safe number, the steel rope sleeve is inconvenient to carry and easily scratches the skin of a worker; the steel rope sleeve has elasticity, and the winding is labor-consuming during working; when the material is prepared, the length of the steel rope sleeve cannot be adjusted, and the time required by field work is directly influenced when the steel rope sleeve is selected to be too long or too short.
in order to achieve the purpose, the invention adopts the technical scheme that:
a universal tangent tower line maintenance cross arm hanging point device comprises a cross arm upper clamp and a cross arm lower clamp, wherein the cross arm upper clamp is in a trapezoidal shape, grooves are symmetrically formed in the front side and the back side of the cross arm upper clamp, a through rectangular groove hole is formed in the middle of the bottom of the cross arm upper clamp, and connecting hole seats and connecting holes are formed in the two sides of the cross arm upper clamp; the cross arm lower clamp is in a triangular shape, grooves are symmetrically formed in the front side and the back side of the cross arm lower clamp, a shaft hole is formed in the middle of the bottom of the cross arm lower clamp and sleeved with a U-shaped annular shaft, and a U-shaped annular sleeve is arranged and connected to the two ends of the U-shaped annular shaft; a screw rod penetrates through the connecting hole and is fastened by a hexagonal screw head; the lower end of the screw rod is respectively connected with the two sides of the lower clamp of the cross arm and is fastened by adopting high-strength bolts.
The utility model discloses a recess cross arm is gone up the card and is passed the lead screw with the cross arm lower card and be connected, and high strength bolt and hexagonal nipple fix above parts, have formed the load component after installation U-shaped ring axle, the U type ring constitute, constitute a general type tangent tower circuit maintenance cross arm hanging point device.
The beneficial effects of the utility model are that, solve present sharp wineglass tower cross arm tower material and be "draft", "not draft" two kinds of condition, adopt new operation method can directly with hanging some device installation, alleviateed the time that the operation personnel lifted by crane, installed to the device possesses hanging some height-adjustable's function, has played the effect of innovation in maintenance work. Compared with a long U-shaped ring method, the device has the advantages of wide adaptability, high safety, convenience in installation and the like, the defects of up-down jumping and left-right sliding in the U-shaped ring operation method are overcome, the structure is more reasonable, the strength is higher, and the safety of the maintenance work of the power line is ensured. The universal hanging point device is wide in adaptability and strong in universality, is suitable for the universal hanging point device with the cross arm back-to-back angle steel spacing larger than or equal to 48 mm and the angle steel height model of 50-220 range full coverage, and solves the problems that the hanging point device is difficult to standardize due to unequal width and various angle steel profiles of the cross arms at the tower head and the potential safety hazard.
