Description

Technical Field

[0001] The invention relates to the field of transmission line rapid repair iron towers, in particular to a convenient pull-up-down conversion structure on a hanging board of a steel pipe tower for transmission line rapid repair. Background Art

[0002] The conventional practice for the tension hanging point of the steel pipe tower is to open a groove of the same thickness as the hanging plate at the hanging point of the cross-arm main pipe. The hanging plate passes through the cross-arm main pipe through this groove and is reliably connected to the cross-arm main pipe by welding. The hanging holes and construction holes are set on the hanging plate and are an integral part of the hanging plate. The bending angle of the hanging plate is used for pulling up or pressing down, and it needs to be clearly specified according to the electrical details table. One hanging plate can only be used for one bending angle.

[0003] The above-mentioned hanging point processing structure has hanging holes and construction holes directly set on the hanging plate, which is directly welded to the crossarm main pipe. As a result, one crossarm main pipe can only be used in one situation of pulling up or pressing down. However, the accident repair site is complex and changeable. The bending angle of the hanging plate may be downward or upward, and the angle size varies. One crossarm cannot meet the use requirements of the uncertain upward and downward situations at the repair site. This means that when encountering dangerous repairs, it is possible to prepare two or even more crossarm main materials to accommodate different pulling up and pressing down situations. Since the crossarm main materials are relatively heavy (a single weight is greater than 70kg) and the repair environment is harsh, this greatly increases the workload of tower material handling at the repair site and increases the repair time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a convenient pull-up-down conversion structure on the hanging plate of a steel pipe tower for emergency repair of a power transmission line, thereby reducing the workload of tower material transportation at the emergency repair site and saving emergency repair time.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A convenient pull-up-down conversion structure for the hanging plate of a steel pipe tower used for emergency repairs of transmission lines, including: Cross arm supervisor; A welding plate, the welding plate being welded to the cross arm main pipe, and a first connecting hole being provided on an upper portion of the welding plate; A wire hanging plate, the wire hanging plate being divided into a first connection portion and a second connection portion by a fire curve, the first connection portion being provided with a second connection hole corresponding to the first connection hole, the second connection portion being provided with a wire hanging hole and construction holes symmetrically arranged on both sides of the wire hanging hole; The hanging plate includes multiple models, and the angle between the first connecting part and the second connecting part of each model is different; In the assembled state, the wire hanging plate is detachably connected to the welding plate by passing bolts through the first connecting hole and the second connecting hole.

[0006] Furthermore, in the above-mentioned convenient pull-out-down conversion structure for the hanging plate on the steel pipe tower for emergency repair of power transmission lines, the angle between the first connecting part and the second connecting part of the hanging plate is 0-45 degrees.

[0007] Furthermore, in the above-mentioned convenient pull-up-down conversion structure for the hanging plate of the steel pipe tower for emergency repair of transmission lines, the angle between the first connection part and the second connection part of the hanging plate is 0 degrees, 10 degrees, 20 degrees, 30 degrees or 40 degrees.

[0008] Furthermore, in the above-mentioned convenient pull-out-down conversion structure of the wire hanging plate on the steel pipe tower for emergency repair of power transmission lines, the weight of the wire hanging plate is less than one seventh of the total mass of the cross arm main pipe, welding plate and wire hanging plate.

[0009] Furthermore, in the above-mentioned convenient pull-out-down conversion structure of the wire hanging plate on the steel pipe tower for emergency repair of power transmission lines, the weight of the wire hanging plate is less than one seventh of the total mass of the cross arm main pipe, welding plate and wire hanging plate.

[0010] Furthermore, in the above-mentioned convenient pull-out-down conversion structure for the hanging plate of the steel pipe tower for emergency repair of power transmission lines, the first connection holes are multiple through holes distributed in a straight array along the axial direction of the cross-arm main pipe.

[0011] The beneficial effects of the present invention are as follows: by dividing the wire hanging plate originally welded to the cross arm main pipe into two independent welding plates and wire hanging plates, the two are bolted together through the first connecting hole and the second connecting hole, which is convenient to install and reliable in connection. A variety of different fire bending angles can be designed between the first connecting part and the second connecting part of the wire hanging plate. By installing the first connecting part and the welding part of the wire hanging plate in the forward and reverse directions, efficient and free switching between pressing down and pulling up can be achieved. Since the wire hanging plate no longer needs to be welded to the cross arm main pipe as a whole, the weight of the wire hanging plate is greatly reduced, which facilitates the installation of wire hanging plates with different fire bending angles; the workload of transporting tower materials at the emergency repair site is reduced, and emergency repair time is saved.

[0013] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0014] Figure 1 as well as Figure 2 What is displayed is the existing technology. The conventional practice for the tension hanging point of the steel pipe tower is to open a groove with the same thickness as the hanging plate 3 at the hanging point of the crossarm main pipe 1. The hanging plate 3 crosses the crossarm main pipe 1 through this groove and is reliably connected to the crossarm main pipe 1 by welding. The hanging hole 321 and the construction hole 322 are set on the hanging plate 3 and are an integral part of the hanging plate 3. The bending angle of the hanging plate 3 is used for pulling up or pressing down, and it needs to be clearly specified according to the electrical detailed list. One hanging plate 3 can only be used for one bending angle.

[0015] Please refer to Figures 3 and 4The specific embodiment of the present invention relates to a convenient pull-up-down conversion structure for a steel pipe tower hanging plate 3 for emergency repair of a transmission line, comprising: Cross arm main 1; A welding plate 2, wherein the welding plate 2 is welded to the cross arm main pipe 1, and a first connecting hole 21 is provided on the upper portion of the welding plate 2; The wire hanging plate 3 is divided into a first connection portion 31 and a second connection portion 32 by a fire curve. The first connection portion 31 is provided with a second connection hole 311 corresponding to the first connection hole 21. The second connection portion 32 is provided with a wire hanging hole 321 and construction holes 322 symmetrically arranged on both sides of the wire hanging hole 321. The wire hanging plate 3 includes multiple models, and the angle between the first connecting portion 31 and the second connecting portion 32 of each model is different; In the assembled state, the wire hanging plate 3 is detachably connected to the welding plate 2 by passing bolts through the first connecting hole 21 and the second connecting hole 311 .

[0016] In the above embodiment, the wire hanging plate 3 that was originally welded as a whole to the cross arm main pipe 1 is divided into two independent parts, the welding plate 2 and the wire hanging plate 3, which are bolted together through the first connecting hole 21 and the second connecting hole 311. A variety of different bending angles can be designed between the first connecting part 31 and the second connecting part 32 of the wire hanging plate 3. Through the forward and reverse installation between the first connecting part 31 and the welding part of the wire hanging plate 3, efficient and free switching between pressing down and pulling up can be achieved. Since the wire hanging plate 3 no longer needs to be welded as a whole to the cross arm main pipe 1, the weight of the wire hanging plate 3 is greatly reduced, which facilitates the installation of wire hanging plates 3 with different bending angles.

[0017] As a preferred embodiment, the angle between the first connection portion 31 and the second connection portion 32 of the wire hanging plate 3 is 0-45 degrees.

[0018] Reference Figures 6 to 13 As a preferred embodiment, the angle between the first connection part 31 and the second connection part 32 of the hanging plate 3 is 0 degrees, 10 degrees, 20 degrees, 30 degrees or 40 degrees. The hanging plate 3 can be installed forward or reverse when connected to the welding plate 2, thereby realizing free switching between pressing down or pulling up, meeting the needs of 9 different angles at the emergency repair site.

[0019] As a preferred embodiment, the weight of the wire hanging plate 3 is less than one-seventh of the total mass of the crossarm main pipe 1, welding plate 2, and wire hanging plate 3. In a specific embodiment, the total mass of the crossarm main pipe 1, welding plate 2, and wire hanging plate 3 is greater than 70 kg, and each wire hanging plate 3 weighs less than 10 kg. This significantly reduces the workload of tower material handling at the repair site and saves valuable repair time.

[0020] As a preferred embodiment, the first connection holes 21 are a plurality of through holes distributed in a straight line array along the axial direction of the cross-arm main pipe 1 .
