[0001] The utility model relates to a steel pipe pole cross arm movable connection structure, belonging to the technical field of electric power steel pipe pole accessories. Background Art

[0002] With the long-term development of my country's electric power industry, the grid of overhead transmission lines has basically been formed. With the needs of power grid construction and social and economic development, the number of reconstruction and expansion projects is increasing. In order to save land, reduce costs and shorten construction period, we try to use the erected poles and towers for reconstruction, and add clamp cross arms to the original steel pipe poles to achieve the purpose of hanging lines.

[0003] Due to the complex site conditions, the angle of the conductor during actual on-site wiring may not be the same as that during design. The commonly used method in the prior art is to weld the clamp base to the outside of the steel pipe pole body and fix the clamp to the clamp base with bolts. This method requires on-site personnel to perform high-altitude welding, or to remove the transmission line on the old pole tower, lay down the old steel pipe pole and install a new cross arm, which is time-consuming and labor-intensive to install.

[0004] In order to solve the above problems, the present application proposes a steel tube rod cross arm movable connection structure. Utility Model Content

[0005] The technical problem to be solved by the utility model overcomes the existing defects and provides a steel pipe pole cross arm movable connection structure.

[0026] Example

[0027] like Figure 1-Figure 7As shown, a steel pipe pole cross arm movable connection structure comprises a steel pipe pole body 1, a cross arm 2 arranged in pairs, and a hoop 3. The hoop 3 is arranged as a polygonal bending structure with the same shape as the outer wall of the steel pipe pole body 1. Unlike the common prior art in which the hoop base is welded to the outside of the steel pipe pole body 1 and the hoop base is fixedly connected to the cross arm 2 by bolts, in the present application, one end of the cross arm 2 is fixedly connected to the hoop 3 by welding, and the end of the hoop 3 is fixedly connected with a connecting plate 5. The connecting plates 5 are fixedly connected to the outer wall of the steel pipe pole body 1 by connecting bolts 7. With this structural design, it is easier to install when adding lines to the old steel pipe pole, and there is no need for workers to risk climbing onto the steel pipe pole to perform dangerous welding work. At the same time, the hanging line angle can be adjusted by adjusting the circumferential installation position of the hoop 3 on the steel pipe pole body 1. A first reinforcing rib plate 4 is fixedly welded between the cross arm 2 and the hoop 3, and a second reinforcing rib plate 6 is fixedly welded between the hoop 3 and the connecting plate 5. The first reinforcing rib plate and the second reinforcing rib plate are used to reinforce the connection.

[0028] In some optional embodiments, a wire hanging plate 8 is fixedly installed on the cross arm 2. The wire hanging plate 8 is used to install power fittings in the prior art and is used together with the power fittings for hanging wires.

[0029] In some optional embodiments, an extension plate 14 is fixedly connected to one of the crossarms 2 via a connecting plate 5, a clamping plate 10 is fixedly connected to the top of the extension plate 14, and a slot 9 is formed between the clamping plates 10 for clamping the connecting plate 5 on the other crossarm 2. During installation, a temporary supporting structure can be formed on the outer wall of the steel pipe rod body 1 through the slot 9 and the connecting plate 5 to facilitate lifting.

[0030] In some optional embodiments, the connecting plate 5 is respectively fixedly connected to a first L-shaped plate 11 and a second L-shaped plate 12 .

[0031] In some optional embodiments, the first L-shaped plate 11 and the second L-shaped plate 12 are arranged in opposite directions in the up and down directions, that is, when the first L-shaped plate 11 is arranged upward, the second L-shaped plate 12 is arranged downward, and when the first L-shaped plate 11 is arranged downward, the second L-shaped plate 12 is arranged upward. When installing the paired clamps 3 and cross arms 2, the first L-shaped plate 11 and the second L-shaped plate 12 are buckled together on the outer wall of the steel pipe rod body 1 to form a temporary supporting structure for easy lifting.

[0032] In some optional embodiments, a wedge plate 13 is further provided between the clamp 3 and the steel tube rod body 1 , and the wedge plate 13 is used to fill the space between the clamp 3 and the steel tube rod body 1 .

[0033] In some optional embodiments, the wedge plate 13 is configured to have a structure that is wide at the top and narrow at the bottom. The specific size design of the wedge plate 13 is determined based on the size of the clamp 3 and the taper of the steel pipe rod before processing. As an independent component, it is convenient to process into different sizes and has better adaptability.

[0034] The common steel pipe rod structure in the prior art is generally set to a structure with a certain taper, a narrow upper part and a wide bottom. In order to adapt to steel pipe rods of different calibers, the clamp 3 is designed to be a vertical structure in the vertical direction. In this way, when the clamp 3 is stuck on the outer wall of the steel pipe rod, a gap is left in the circumferential direction, which will cause the upper part of the clamp 3 to not be tightly clamped. By adding a wedge-shaped plate 13 with a wide top and narrow bottom structure, the connection between the clamp 3 and the steel pipe rod can be clamped tightly, the contact area is increased, and the fixing effect is better.

[0035] A cross arm movable connection structure of a steel pipe pole is connected by directly welding a cross arm 2 with a clamp 3 and installing the clamp 3 on the steel pipe pole body 1 with a connecting bolt 7. The installation is more convenient when adding a cross arm to an old steel pipe pole for line modification. The angle adjustment and installation position adjustment can be achieved when installing a new steel pipe pole upright, and the adaptability is stronger.

[0036] The above is a preferred implementation mode of the utility model. The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Technical personnel in this industry should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
