Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel support, in particular to a large-diameter anchor cable quick installation tool. Background Art

[0002] Bottom extraction tunnel, also known as floor tunnel, is located in the rock layer below the coal seam. It refers to the tunnel arranged on the bottom plate of the coal seam. The bottom extraction tunnel is excavated along the limestone bottom plate under the working face. The tunnel section is rectangular, with a net width of 4800mm and a net height of 4150mm. The support method is initial spraying + anchor net cable + grouting support. Among them, the anchor net cable support formed by multiple anchor cables is more troublesome to install. The anchor net cable support is to extend the anchor cable into the anchor cable hole for connection support, but it has the following disadvantages in actual operation:

[0003] A roof is set up under the tunnel for auxiliary support. Usually, when installing anchor cables, an MQT-130 / 3.2 pneumatic anchor drill (equipped with a B19 hollow hexagonal drill rod and a φ38mm alloy steel half-piece drill bit) is used to drive the roof reinforcement support anchor cables in the back tunnel. Due to the influence of mine pressure, the local roof is deformed and cracks are generated, and the anchor cable holes are prone to collapse. In addition, the anchor cable has a large diameter and a large weight. During the installation of the anchor cable, the resistance brought by the rock formation on the hole wall is large when the anchor cable penetrates the bottom of the hole. It is more laborious to manually wear the anchor cable. Usually, 2 to 3 people are required to hold the anchor cable together and push it upward, resulting in the entire installation process of an anchor cable taking about 1 hour (excluding the tension anchor cable). In a production shift (8 hours), 2 support workers can only drive up to 3 φ28.6×8250mm reinforcement support anchor cables. For the rapid completion of the bottom extraction tunnel reinforcement support and active support to reduce the impact of mine pressure, the support efficiency is far from enough, which is not conducive to roof management.

[0004] Secondly, when inserting the anchor cable into the anchor cable hole, because manual insertion of the anchor cable is laborious in itself, it is also necessary to align the anchor cable hole for insertion, which is even more time-consuming and labor-intensive. This leads to lower efficiency of the anchor cable support processing and lack of auxiliary positioning structure. Utility Model Content

A circular hole 1 501 and a circular hole 2 502 are opened in the connecting plate 5. The connecting plate 5 is sleeved on the outside of the drill rod 301 through the circular hole 1 501, and the anchor cable body 6 is inserted in the circular hole 2 502.

[0027] When inserting the anchor cable body 6, the connecting plate 5 is sleeved on the outside of the drill rod 301 through the circular hole 1 501, and then the end of the anchor cable body 6 is passed through the circular hole 2 502. At this time, the connecting plate 5 is supported and tilted by the limit block 302, and the tail end of the anchor cable body 6 is placed on the roller 202 and is simply limited by the limit piece 203, so that the tail end of the anchor cable body 6 is pulled in the direction of the roller 202, so that under the self-gravity of the anchor cable body 6, the connecting plate 5 is used to complete the self-locking. If the force is insufficient, the tail end of the anchor cable body 6 can be slightly pulled manually to apply a certain force so that the anchor cable body 6 will not slip in the circular hole 2 502, and the self-locking is completed; finally, the air supply valve of the anchor bolt machine 3 is opened, and the air leg of the anchor bolt machine 3 is slowly raised.
