Description

Technical Field

[0001] The present invention relates to the technical field of transmission towers, and in particular to a transmission tower. Background Art

[0002] Transmission towers are structures that support the conductors and lightning conductors of high-voltage or ultra-high-voltage overhead transmission lines. Transmission towers are tall structures that are very sensitive to tilt and deformation and have high requirements for uneven foundation settlement.

[0003] In the mining-affected area, the continuous mining of minerals causes the mechanical changes of the rock strata to continue. The traditional transmission tower foundation is formed in one go. Once a change occurs, the mechanical change will cause the transmission tower to tilt or the position of the transmission tower to change. Therefore, in the mining-affected area, it may be necessary to fix the foundation multiple times, or to dig the foundation very deep before it can be used. However, once the foundation is formed, it is difficult to adjust the position of the foundation and the tower, which can easily lead to the tower and / or foundation being scrapped, causing waste. Alternatively, the original concrete foundation may be demolished and a new foundation may be laid, damaging the ground. In addition, construction waste will be generated and the ground needs to be refilled and compacted before the foundation can be laid again, which is time-consuming and labor-intensive. Therefore, there is a need for a transmission tower that can easily adjust the angle and position to adapt to the mining-affected area. Summary of the Invention

[0010] Preferably, the angle is adjusted by rotating the rope winding member to adjust the force applied to the three limit modules, and the ground is compacted after the angle is adjusted;

[0011] When the position needs to be adjusted, the rope is loosened, the insert is taken out and the ground is re-compacted, and the rigid pipe is reinserted into the channel and reinserted after finding the predetermined position or the angle is readjusted after insertion.

[0012] Preferably, the rope winding member includes a rope winding drum and a ratchet group, the ratchet group includes a wheel seat, a ratchet, a pawl, a spring and a rotating shaft, the rotating shaft is rotatably connected to the wheel seat, the ratchet is set on the rotating shaft, the pawl is rotatably fixed to the wheel seat, one end of the spring is fixed to the wheel seat, and the other end presses against the pawl so that the pawl cooperates with the ratchet; the rope winding drum is connected to the rotating shaft.

This can reduce costs while greatly improving work efficiency and generating no construction waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] 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.

[0026] Please refer to Figures 1 to 3 , a transmission tower, comprising:

[0027] The tower body 2 includes a tower body 21 and at least three tower legs 22; the tower legs 22 are connected to the bottom of the tower body 21;

[0028] The base 3, the number of which corresponds to the number of tower legs 22; the base 3 includes a base 31, a connecting seat 32 and three groups of limiting modules 33, the tower legs 22, the connecting seat 32, the base 31 and the limiting modules 33 are connected in sequence from top to bottom, the limiting modules 33 include a rigid pipe, a limiting rope 339, a rope winding member 331, an inserting plate 332 and a plurality of connecting plates 333, the inserting plate 332 includes an inserting end and a connecting end, the inserting end is set at an acute angle 334, and an arc groove 335 is provided on the connecting end; the connecting plate 333 includes an arc convex end 336 and an arc groove 335 that is the same as the arc groove 335 of the inserting plate 332; the inserting plate 332 is a head and a plurality of connecting plates 333 are connected in sequence through the arc convex end 336 and the arc groove 335 to form an insert body; the insert body is provided with two parallel channels that pass through the insert body; one of which is a through The first and second ends of the cam 330 are provided with a plurality of holes 311 for connecting the cables 337 to the first and second ends of the cam 330. The second end of the cam 330 is provided with a plurality of holes 311 for connecting the cables 337 to the first and second ends of the cam 330.

[0029] When the position needs to be adjusted, the rope member 331 is loosened, the inserting body is taken out, the rigid pipe is reinserted into the channel, and after finding the predetermined position, the rigid pipe is reinserted into the ground 1 or the angle is readjusted after insertion.

[0030] As can be seen from the above description, through the three groups of limiting modules 33, through the setting of the rigid pipe, by inserting or removing the rigid pipe, sufficient rigidity can be guaranteed when inserting into the ground 1, and after removal, the positions of the arc-shaped protruding ends 336 and the arc-shaped grooves 335 between the insertion plate 332 and the plurality of connecting plates 333 can be appropriately changed, and then the rope winding member 331 is coordinated with the vertically arranged wiring hole 311, and the rope winding member 331 is tightened along the vertical wiring hole 311, so that the limiting rope 339 has a tendency to converge toward the center, that is, the force applied to the two inserted bodies is changed, for example, after being tightened, the rope winding member 331 is deformed when tightened to gather the soil inward, so that the foundation force on one side of the tightened limiting rope 339 is greater. The angle can be adjusted according to the deformation characteristics of the soil to cope with the angle change caused by the force change in the mining-affected area, so that the angle can be adjusted without re-laying the foundation. The setting of the arc-shaped protrusion and the arc-shaped groove 335 can facilitate the deformation of the entire insertion plate 332 in the soil, resulting in a better contraction effect and avoiding the difficulty of contraction due to excessive rigidity. If the foundation position needs to be adjusted, only the three insertion bodies need to be taken out and re-positioned. The foundation formed by the original three insertion bodies disappears and will not interfere with the subsequent reinsertion. There is no need to destroy the original foundation and then lay the foundation as in the traditional way. It can reduce costs while greatly improving work efficiency and no construction waste is generated.

[0031] Furthermore, the angle is adjusted by rotating the rope winding member 331 to adjust the force applied to the three limit modules 33. After the angle is adjusted, the ground 1 is compacted.

[0032] When the position needs to be adjusted, the rope member 331 is loosened, the insert is taken out and the ground 1 is re-compacted, and the rigid pipe is reinserted into the channel and reinserted after finding the predetermined position or the angle is readjusted after insertion.

[0033] As can be seen from the above description, by re-compacting the ground 1 , the compaction of the ground can be ensured and the adjustment range of the rope winding member 331 can be reduced.

[0034] Furthermore, the rope winding member 331 includes a rope winding drum 3311 and a ratchet 3313 group, the ratchet 3313 group includes a wheel seat 3312, a ratchet 3313, a pawl 3314, a spring 3315 and a rotating shaft 3316, the rotating shaft 3316 is rotatably connected to the wheel seat 3312, the ratchet 3313 is set on the rotating shaft 3316, the pawl 3314 is rotatably fixed to the wheel seat 3312, one end of the spring 3315 is fixed to the wheel seat 3312, and the other end presses against the pawl 3314 so that the pawl 3314 cooperates with the ratchet 3313; the rope winding drum 3311 is connected to the rotating shaft 3316.

[0035] From the above description, it can be seen that the arrangement of the ratchet 3313 group facilitates the winding of the rope and the adjustment of the limiting rope 339 .

[0036] Furthermore, the ratchet wheel assembly 3313 further includes a rocker arm 3317 , and the rocker arm 3317 is connected to the rotating shaft 3316 .

[0037] As can be seen from the above description, the rocker arm 3317 can be used to wind the limit rope 339 when it is relatively loose.

[0038] Furthermore, a polygonal column 3318 is provided on the rotating shaft 3316 .

[0039] From the above description, it can be seen that through the setting of the polygonal column 3318, it is convenient to use the lever principle to amplify the force to achieve adjustment.

[0040] Furthermore, the connecting seat 32 is a liftable connecting seat 32 .

[0041] It can be seen from the above description that, by means of the liftable connecting seat 32 , changes in the vertical direction can be eliminated directly through the connecting seat 32 when the ground 1 sinks or rises.

[0042] Furthermore, the surfaces of the inserting plate 332 and the connecting plate 333 are rough surfaces.

[0043] It can be seen from the above description that the friction between the insert plate 332, the connecting plate 333 and the soil surface can be increased by the rough surface.

[0044] Furthermore, the upper surface of the base 31 is an inclined surface that slopes from the inside to the outside.

[0045] From the above description, it can be seen that by tilting from the inside to the outside, drainage can be facilitated and water accumulation and corrosion can be avoided.

[0046] Furthermore, the limiting module 33 further includes a cover body, and a slot for the connecting seat 32 to pass through is provided on the cover body. When the cover body is mounted on the base 31 , the connecting seat 32 passes through the slot.

[0047] It can be seen from the above description that the provision of the cover body can prevent the limiting rope 339 and the rope winding member 331 from being damaged by external forces.

[0048] Furthermore, the inner wall of the channel and both ends of the channel are polished.

[0049] As can be seen from the above description, the polishing process can prevent burrs or sharp edges on the inner wall from causing wear to the limiting rope 339. Example 1
