Flexible earth anchor drilling and taking machine

Abstract

The invention discloses a flexible earth anchor drilling and taking machine, comprising a prime motor capable of walking and a portal frame arranged on the prime motor. The portal frame is provided with a feeding mechanism, a driving cylinder and an earth anchor drilling and taking mechanism thereon. The driving cylinder is connected with the earth anchor drilling and taking mechanism in a transmission way through the feeding mechanism. The drilling and taking machine also comprises a landing leg and a pull rod, wherein the landing leg is vertically arranged on the prime motor and near the portal frame, two ends of the pull rod are respectively articulated with the prime motor and the portal frame, the lower part of the portal frame is articulated with the prime motor. The drilling and taking machine integrates walking and operating into one piece of special equipment, causes a hydraulic power rotary helical slice to enter earth to certain depth, depends on the withdrawal resistance of the helical slice against the earth mass to form anchoring force, and can take out the flexible earth anchor after use for reuse, thus realizing mechanical construction and improving the efficiency of preparation for line construction to great degree.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, and in particular relates to a flexible ground anchor drilling and extraction machine. Background technique [0002] Ground anchor is a load-bearing device widely used in the construction of power transmission lines. There are two types of ground anchors that are often used, one is buried log or iron ground anchor. At present, in the construction process of power transmission lines in China, ground anchors are generally used. At present, there is no equipment and technology for mechanized burying ground anchors. The efficiency of construction preparation is very low. most backward. In construction, it takes half a day for two workers to bury a small ground anchor, and it takes one day to bury a larger ground anchor. Taking into account the time it takes to dig out the used ground anchors, it takes an average of one day to set the ground anchors. The other is an earth drill,...

AI Technical Summary

Problems solved by technology

At the same time, the ground anchor can no longer be taken out from the soil, and the ground anchor cannot be reused, but can only be left in the soil, causing a lot of waste

[0007] In addition, the length of the anchor is fixed. Sometimes the depth of the ground anchor is different due to the difference in soil quality. Sometimes the anchor may be exposed to the ground.

If the anchor rod exposed to the soil is too long, it will be easily bent and inconvenient to use

Furthermore, this kind of ground anchor is relatively heavy, takes up a lot of space when placed, and is inconvenient to transport.

[0008] It is very troublesome to put the ground anchor into the ground and then take it out, so the used ground anchor is generally left in the ground, which not only has certain safety hazards, but also is a waste
