Embodiment 1

[0063] see Figure 1 to Figure 12 , the present invention provides an electromagnetic support type drilling and anchoring integrated machine, comprising a driving device 1, an anchor rod 2 and a plurality of electromagnetic anchoring devices 4 arranged on the outer peripheral wall of the anchor rod 2, and a plurality of electromagnetic anchoring devices 4 along the anchor rod 2 The circumferential direction is arranged in rows, at least two rows, and a plurality of electromagnetic anchoring devices 4 in each row are uniformly arranged in the axial direction of the anchor rods 2 . The electromagnetic anchoring device 4 is used to insert into the wall of the anchor hole to play a supporting role. The anchor rod 2 has opposite first end portions 23 and second end portions 24, and the anchor rod 2 extends between the first end portion 23 and the second end portion 24 in a rod shape. In this embodiment, the anchor rod 2 is a circle rod-shaped. The second end portion 24 of the anc...

Embodiment 2

[0077] The electromagnetic support type drill and anchor integrated machine described in this embodiment is based on the first embodiment, and the connection structure between the soil removal device 5 and the second gear shaft 124 is changed. In this embodiment, the soil removal device 5 and the second gear shaft 124 are changed. The second gear shaft 124 is connected through the locking sleeve 10, and the specific connection structure is as follows:

[0078] see Figure 13 and Figure 14 , The soil removal device 5 is fixedly connected with the second gear shaft 124 through the locking sleeve 10 . Specifically, the locking sleeve 10 is a hollow structure, specifically a cylindrical shape. One end is provided with a single row of card edges 102 pointing to the center, and the other end is an internal thread 101 structure. The card edge 71 can be an annular inner flange, or a plurality of arc-shaped flanges arranged at intervals along the circumferential direction of the lo...

Abstract

The invention relates to an electromagnetic supporting type drilling and anchoring integrated machine and an anchoring method. The electromagnetic supporting type drilling and anchoring integrated machine comprises a driving device, an anchor rod and multiple electromagnetic anchoring devices arranged on the peripheral wall of the anchor rod. A tool bit is arranged at one end of the anchor rod, and the driving device is detachably and fixedly connected to the other end of the anchor rod and can drive the anchor rod to rotate so as to drive the tool bit to drill an anchor hole. A through hole is formed in the anchor rod, a soil removing device is arranged in the through hole in a sleeved manner, the soil removing device is detachably connected with the driving device, and drilled muck is discharged from a soil discharging hole under driving of the driving device. The soil discharging hole is formed in the peripheral wall of the anchor rod and communicates with the through hole. An electromagnetic driving unit is arranged on the driving device, and after drilling, the electromagnetic driving unit controls the electromagnetic anchoring devices to be inserted into the wall of the anchor hole to achieve supporting. During recovery, the electromagnetic driving unit controls the electromagnetic anchoring devices to be pulled out of the wall of the anchor hole, and then the anchor rodis recovered. Drilling and supporting are integrated, the pre-drilling procedure is omitted, the anchoring efficiency is improved, and the anchoring cost is reduced.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering reinforcement, in particular to an electromagnetic support type integrated drilling and anchoring machine and an anchoring method. Background technique [0002] Anchor bolts are a major support form in water conservancy and hydropower projects, underground projects, foundation pit projects and slope projects, and play a vital role in the stability of the project. more obvious. [0003] When anchoring and supporting anchor bolts at this stage, it is necessary to drill anchor holes with a drilling machine or a pile driver in advance, and then support them. The anchor rods are not recyclable, resulting in waste of steel and increased anchoring costs. Contents of the invention [0004] (1) Technical problems to be solved [0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an electromagnetic support type drilling a...
