Description

Fully hydraulic intelligent drilling, installation and anchoring machine

Technical Field

The present invention relates to the technical field of coal mine boring machines, and in particular to a fully hydraulic intelligent drilling, mounting and anchoring integrated machine.

Background Art

With the rapid development of the national economy, coal mine boring machines have gradually become the main equipment for coal mine tunnel mining. However, in rock tunnels with higher rock hardness, drilling and blasting methods are generally used for development.

At present, the construction method of rock tunnel drilling and blasting has the following problems:

1. Manual drilling + loading machine collecting materials + belt conveyor unloading gangue: After manual drilling, the blasting machine drives the belt conveyor to the designated position of the tunnel to collect materials. The disadvantages are as follows:

(1) Manual drilling takes a long time, is labor-intensive, and the slag water deteriorates the working environment and is highly dangerous;

(2) The equipment needs to be moved repeatedly to complete the drilling;

(3) Anchor bolts need to be driven manually, which is labor-intensive and has low labor efficiency.

2. Hydraulic trolley + loader + belt conveyor for gangue discharge: A hydraulic trolley is used for drilling. After the blast, the loader drives the belt conveyor to form a continuous transportation system for gangue discharge. The disadvantages are as follows:

(1) Hydraulic trolleys and loaders need to be repeatedly moved and staggered in the tunnel. Workers need to repeatedly drag cables, water pipes, and gas pipes, which is labor-intensive;
