Description

Technical Field

[0001] This invention relates to the field of power transmission towers, and more particularly to a steep-slope tower structure that can correct installation errors. Background Technology

[0002] my country is a country with full power coverage. The installation environment of power transmission towers is complex and diverse. When erecting high-altitude transmission lines in mountainous areas, the existing tower structures are very inconvenient to install due to the steep slopes. If the steep slopes are cleared to make them flat, the amount of work is enormous. Moreover, after clearing them to make them flat, the side closest to the steep slope will form an even steeper slope, which is prone to collapse.

[0003] In the existing technology, based on the structure of the steep slope, a tower mounting frame with one side higher and the other lower is designed, which can reduce the amount of construction work. However, this method requires that the tilt angle of the steep slope be exactly the same as the tilt angle of the bottom surface of the designed tower mounting frame. If they are not the same, the installed tower will be tilted, which poses a great safety hazard and greatly limits the promotion and application of this method. Therefore, this application provides a new type of steep slope tower structure that can correct installation errors. Summary of the Invention

[0033] The invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] refer to Figures 1 to 4A steep slope iron tower structure that can correct installation errors includes: a first section 1, a second section 2, a third section 3, a first concrete base 6, a second concrete base 7, a first support frame 9, a second support frame 16, and an adjustable tie rod 15.

[0035] The bottom of the second segment 2 is fixedly connected to the top of the first segment 1, and the bottom of the third segment 3 is fixedly connected to the top of the second segment 2. A first angle steel main frame 101 is installed on the lower side of the first segment 1 near the steep slope, and a second angle steel main frame 102 is installed on the lower side of the first segment 1 away from the steep slope. The length of the first angle steel main frame 101 is greater than the length of the second angle steel main frame 102. After the first angle steel main frame 101 and the second angle steel main frame 102 are installed, the top of the first segment 1 is in a horizontal state, facilitating the installation of the second segment 2 and the third segment 3. Sections 2 and 3 are not modified in this scheme and can be installed using any method on flat ground. The first concrete base 6 is located below the steep slope, and the top of the first concrete base 6 has a short screw 8; the second concrete base 7 is located above the steep slope, and the top of the second concrete base 7 has a long screw 12; the lengths of the first concrete base 6 and the second concrete base 7 embedded in the soil are basically the same. Due to the terrain, the height of the second concrete base 7 will be higher than the height of the first concrete base 6, and it is basically the same as the height of the first angle steel main frame 101 and the second angle steel main frame. The bottom height difference of the first support frame 102 is basically the same; the bottom end of the first support frame 9 is fixedly connected to the short screw 8, and a fixing pad 11 is provided between the bottom end of the first support frame 9 and the top of the first concrete base 6. Specifically, the short screw 8 passes through the fixing pad 11 and the bottom end of the first support frame 9, and then a tightening nut is threaded onto the short screw 8 for fixation. The bottom end of the first angle steel main frame 101 has a first main frame mounting seat 10, and the first main frame mounting seat 10 is fixedly connected to the top end of the first support frame 9 by bolts; the bottom end of the second support frame 16 is fixedly connected to the long screw 12. Furthermore, an adjustable pad 13 is provided between the bottom end of the second support frame 16 and the top end of the second concrete base 7. Specifically, a long screw 12 passes through the adjustable pad 13 and the bottom end of the second support frame 16, and then a tightening nut is threaded onto the long screw 12 for fixation. The bottom end of the second angle steel main frame 102 has a second main frame mounting seat 14, and the second main frame mounting seat 14 is fixedly connected to the top end of the second support frame 16 by bolts. One end of the adjustable pull rod 15 is movably connected to the first support frame 9, and the other end of the adjustable pull rod 15 is movably connected to the second support frame 16.

[0036] according to Figure 2 Install the first section 1 at the structural position shown in the diagram. After installation, the construction personnel will check the overall tilt angle of the first section 1 and then adjust the tilt angle using the adjustable pad 13 before installing the second section 2 and the third section 3.

[0037] The adjustment principle is as follows: The user controls the height of the adjustable pad 13 to increase or decrease (the adjustment direction is determined by measurement), and at the same time adjusts the length of the adjustable pull rod 15 so that it can be adjusted stably. After the adjustment is completed, tighten the pressing nuts on the short screw 8 and the long screw 12 to fix them.

[0038] In one embodiment, the bottom end of the short screw 8 is embedded inside the first concrete base 6, and the short screw 8 is welded and fixed to the reinforcing steel inside the first concrete base 6; the bottom end of the short screw 8 is welded and fixed to the reinforcing steel before the first concrete base 6 is poured, and then the concrete is poured.

[0039] The bottom end of the long screw 12 is embedded inside the second concrete base 7, and the long screw 12 is welded and fixed to the steel bars inside the second concrete base 7; the bottom end of the long screw 12 is welded and fixed to the steel bars before the second concrete base 7 is poured, and then the concrete is poured.

[0040] Reference Appendix Figure 1 In one embodiment, two symmetrical first supports 4 are provided on the side of the second segment 2, and two symmetrical second supports 5 are provided on the side of the third segment 3. Both the two symmetrical first supports 4 and the two symmetrical second supports 5 are umbrella-shaped and are used to support the high-voltage line.

[0041] Reference Appendix Figure 4 In one embodiment, the adjustable pad 13 includes: a base plate 131, a top plate 132, a first support plate 133, and a second support plate 134.

[0042] The base plate 131 has a positioning recess 135 at the top center; the top plate 132 is located above the base plate 131, and the top of the top plate 132 is threadedly connected to an adjusting screw 136. The bottom end of the adjusting screw 136 is fixedly connected to a hexagonal block 137, and the bottom end of the hexagonal block 137, located inside the positioning recess 135, is fixedly connected to a spherical head 138; the bottom end of the first support plate 133 is movably connected to the base plate 131, the top end of the first support plate 133 is movably connected to the bottom end of the second support plate 134, and the top end of the second support plate 134 is movably connected to the top plate 132.

[0043] The principle of height adjustment of adjustable pad 13: The user turns the hexagonal block 137 of adjusting screw 136 with a wrench, so that the adjusting screw 136 and the top plate 132 rotate, causing the adjusting screw 136 to move up and down. Since the bottom end of adjusting screw 136 is supported at the positioning recess 135, it can be well ensured that adjusting screw 136 is always in a vertical state and will not tilt or deform. Relying on the support of adjusting screw 136, the distance between bottom plate 131 and top plate 132 is adjusted, thereby achieving the purpose of adjusting the height of adjustable pad 13.

[0044] Reference Appendix Figure 2In one embodiment, the adjustable lever 15 includes: a first screw 151, a second screw 152, and a double-ended screw 153.

[0045] One end of the first screw barrel 151 is movably connected to the first support frame 9; one end of the second screw barrel 152 is movably connected to the second support frame 16; both ends of the double-ended screw 153 are threadedly connected to the first screw barrel 151 and the second screw barrel 152 respectively, and the side of the double-ended screw 153 is provided with a hexagonal part.

[0046] The user can adjust the overall length of the adjustable rod 15 by rotating the double-ended screw 153, which causes the first screw 151 and the second screw 152 to rotate threadedly at both ends, making the first screw 151 and the second screw 152 move closer or further apart.

[0047] The fixed pad 11 has a first through hole, the short screw 8 is located inside the first through hole, the adjustable pad 13 has a second through hole (the second through hole refers to the through holes on the bottom plate 131 and the top plate 132), and the long screw 12 is located inside the second through hole.

[0048] The top heights of the first angle steel main frame 101 and the second angle steel main frame 102 are the same. This ensures that after the first section 1 is installed, the top of the first section 1 is horizontal, facilitating the installation of the second section 2 and the third section 3.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
