Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line design, and in particular to a horizontal jumper connection structure. Background Art

[0002] In the construction of drilling towers, the terrain at the drilling site is often steep, resulting in the situation that the distance between the side phase of the drilling tower and the ground does not meet 7.5m. Since the side phase jumper string of the drilling tower is normally placed vertically, the side phase jumper is not far enough from the ground, which requires the drilling tower to be raised and the construction cost to be increased. At the same time, the traditional jumper connection method is basically fixed and cannot be changed, resulting in insufficient flexibility during installation and the inability to adjust the side phase angle during installation.

[0003] Based on this, in order to solve the problems of insufficient distance between the edge phase and the ground and inflexible installation in steep terrain, this design proposes a horizontal jumper connection structure. Utility Model Content

[0010] 1. The utility model provides an adjustment device and a pull rod. The adjustment device can move to a certain extent. During installation, the purpose of installing the column composite insulator can be achieved by squeezing or stretching the support rod.

DETAILED DESCRIPTION

[0020] The utility model is further explained clearly and completely below in conjunction with the drawings in the specification, but the protection scope of the utility model is not limited thereto.

[0021] according to Figure 1 , Figure 2 and Figure 3 As shown, a horizontal jumper connection structure in the utility model comprises: a first cross arm 1, an upper conductor 2, an iron frame 3, a second cross arm 4, a support rod 6, a support rod base 7, a column composite insulator 8, a lower conductor connecting device 9, a lower conductor 10, an adjusting device 11, a limiting rod 12, and a pull rod 13. The upper conductor 2 passes through the first cross arm 1, the lower conductor 10 is installed on the second cross arm 4 installed in the middle of the iron frame 3, the lower conductor is installed with an adjusting device 11, and the adjusting device 11 is installed with a support rod 6. There are two support rods 6, which are distributed up and down. The limiting rod 12 is installed at the far end of the support rod 6, and the column composite insulator 8 is installed between the second cross arm 4 and the limiting rod 12. The pull rod 13 is installed on the upper part of the limiting rod 12. The pull rod 13 can ensure that the support rod 6 will not deviate downward, and the angle between the support rod 16 and the second cross arm 4 can be changed by changing the length of the pull rod 13.

[0022] Specifically, according to Figures 4 to 8 As shown, the adjusting device 11 includes: a fixing device 110, a limiting device 111, a moving block 112, a spring 113, a telescopic rod 114, a block 115, a compression spring 116, and a slot 117. The limiting device 111 is a rectangular structure and is provided with a slot 117 inside. The moving block 112 is installed in the slot 117. The telescopic rod 114 and the spring 113 are connected to the right side of the moving block 112. By manually pushing the moving block, the moving block 112 can be moved inside the slot 117 of the limiting device 111.

[0023] Specifically, through Figure 7 and Figure 8 As shown, at the opening on the right side of the slot 117 of the limit device 111, a block 115 is distributed above and below. The block 115 is a triangular structure, with the inclined surface of the block 115 on the left and the vertical surface on the right. When the moving block 112 slides to the right in the slot 117, the block 115 will pop up every time it slides one grid, thereby locking the moving block 112 to adjust the position of the moving block 112. At the same time, since the support rod 6 is installed on the moving block 112, when the moving block 112 moves, it will squeeze the support rod 6, causing the farthest end of the support rod 6 to be away from the iron frame 3. At this time, the support rod 6 can be installed with a longer column composite insulator 8.

[0024] Furthermore, through the cooperation between the pull rod 13 and the adjusting device 11, the angle between the adjusting device 11 and the second cross arm 4 can be adjusted to adapt to the complex terrain conditions on site, thereby improving the convenience of conductor installation, improving the fault tolerance of construction, and saving time and labor costs.
