Description

Earth anchor for electric power construction

Technical Field

The invention relates to a ground anchor for electric power construction, and belongs to the technical field of line construction devices.

Background

In the construction process of the power transmission line, equipment such as a tension machine, a tractor and the like and other stressed ropes and the like are often required to be anchored, and the conventional anchoring method comprises the following steps: the method comprises the steps of excavating an anchor pit, arranging a packway, placing a steel plate anchor at the bottom of the anchor pit, aligning a pull ring of the steel plate anchor with the direction of the packway, connecting a steel wire sleeve or a stay bar on the pull ring of the steel plate anchor through a U-shaped ring, placing the steel wire sleeve or the stay bar in the packway in an inclined upward direction, backfilling and tamping the anchor pit, and taking a rope head or the stay bar pull ring exposed out of the ground as an anchoring connection point. And after the anchoring needs to be finished, digging backfill, taking out the steel plate ground anchor, the steel wire sleeve or the anchor rod and the U-shaped ring, and cleaning for next use. The existing anchoring method has the defects of large construction period and environmental influence, difficult excavation of an anchoring pit when the geology is hard, high compensation cost, incapability of ensuring the anchoring force when the geology is too soft and the like, and the ground anchor is unstable to fix and is easy to incline and fall down.

The invention relates to a ground anchor for electric power construction, which is characterized by comprising a first anchor post 1 and a second anchor post 2 nested in the first anchor post 1, wherein the first anchor post 1 is in screwed connection with the second anchor post 2, a detachable helical blade 4 is arranged at the position, close to the lower part, of the first anchor post 1, a screw seat 5 is arranged at the top of the first anchor post 1, a through hole is formed in the width direction of the screw seat 5, a screw rod 6 is arranged in the through hole, a base 7 is arranged below the bottom of the screw seat 5, two horizontal arms 8 are arranged at the left side and the right side of the base 7, through holes 9 are formed in the two horizontal arms 8, an auxiliary supporting mechanism is arranged in the through holes 9, a driving motor 10 for driving the second anchor post 2 to rotate is arranged at the top of the screw seat 5, the driving motor 10 simultaneously controls the auxiliary supporting mechanism to be fixed with the ground, and a suspension device 11 is arranged on the side wall of the screw;

the auxiliary supporting mechanism comprises a drill rod 12 arranged in the through hole 9, an upper seat 13 with the diameter larger than that of the through hole 9 is arranged at the top of the drill rod 12, and the upper seat 13 is controlled by a driving motor 10;

the first anchor column 1 and the second anchor column 2 are both hollow columns and made of rigid materials, and the bottom of the second anchor column 2 is sharp;

a plurality of spaced holes 3 have all been seted up on first anchor post 1 and the 2 direction of height of second anchor post, can make soil get into in first anchor post 1 or the second anchor post 2 through hole 3, further improve the steadiness.

The ground anchor for electric power construction is ingenious in structural design, the second anchor post 2 is driven to be contracted into the first anchor post through the driving motor, the rotary rod is inserted into the rotary seat, the rotary rod is rotated to slowly insert the first anchor post into the ground, after the first anchor post is inserted into the ground for a certain distance, the driving motor is started, the driving motor drives the second anchor post to extend out of the first anchor post, further stabilizing effect is achieved, meanwhile, the drill rod is inserted into the ground, the driving motor drives the drill rod to be inserted into the ground, and the two horizontal arms are tightly attached to the ground, so that the ground anchor is further stabilized. In conclusion, the anchor is firm in anchoring, easy to excavate and beneficial to ecological sustainable development.
