Description

Technical Field

[0001] The utility model relates to the technical field of mine anchor support equipment, in particular to a drilling and anchoring system and an anchoring machine suitable for coal mine tunnels. Background Art

[0002] With the development of coal mines, in order to ensure the balance of mining and excavation, the requirements for tunnel excavation footage are getting higher and higher. At present, the tunnel excavation speed and the anchor support speed are unbalanced. The anchor support speed is much lower than the excavation speed, which greatly restricts the tunnel excavation footage progress. Cantilever tunnel boring machines are widely used because of their flexible excavation and wide adaptability to geological conditions. Cantilever tunnel boring machines with drilling and anchoring systems are the key research and development direction for improving tunnel excavation footage. At present, most of the drilling and anchoring systems with an anchor drilling rig are arranged on the left and right sides of the cantilever tunnel boring machine. The number of anchor drilling rigs is small, the tunnel anchor support efficiency is low, and the anchor drilling rig is not very effective in drilling and anchoring. There are problems such as low efficiency of mobile positioning in front of the rod hole, small operating platform of anchor drilling rig, and limited working range of operators; for tunnels with unstable surrounding rock, it is necessary to complete anchor support on the top and two sides exposed after excavation in a timely and rapid manner to ensure the stability of the tunnel surrounding rock and the quality of tunnel formation. Therefore, it is necessary to have multiple anchor drilling rigs that can simultaneously perform anchor support operations on the same row of the top plate and two sides exposed after excavation, so as to make up for the problem that the existing anchor drilling rig has four anchor drilling rigs but can only perform anchor support operations on the tunnel top plate at the same time. The four anchor drilling rigs that can support the top plate at the same time do not have the function of anchor support operations on the two sides of the tunnel. Summary of the Invention

[0003] The utility model provides a drilling and anchoring system and an anchor boring machine to solve the above problems. Two anchor drilling machines are arranged on the drilling and anchoring system. The two anchor drilling machines can simultaneously perform anchor support operations on the exposed roof of the tunnel and the same row of anchors on both sides, and can also perform anchor support operations on multiple rows of anchors in the tunnel at the same time. Reasonable mechanism design makes the movement and positioning of the anchor drilling machines simple, and improves the positioning efficiency of the anchor drilling machines in drilling anchor holes. The operators can walk on the working platform, and the operators have a large working range and high flexibility. The two sets of drilling and anchoring systems are installed on the tunnel boring machine, namely the anchor boring machine, so that the tunnel boring machine has the function of four anchor drilling machines to simultaneously perform anchor support operations on the exposed roof of the tunnel and the same row of anchors on both sides. The four anchor drilling machines also have the function of simultaneously performing anchor support operations on multiple rows of anchors in the tunnel, and can adapt to the different construction requirements of tunnels with different geological conditions.

[0011] In the above technical solution, in one embodiment, the second slide rail includes a second slide frame provided with a rack, and the second push-pull cylinder is connected to the second slide frame provided with the rack.

[0012] The utility model also provides an anchor drill, comprising the above-mentioned anchor drilling system.

[0013] The effective benefits of the present invention are as follows: the drilling and anchoring system provides two drilling and anchoring devices, which can simultaneously support the same row of anchor rods on the exposed roof and side walls of the tunnel, greatly improving the support efficiency. The two drilling and anchoring devices can also support multiple rows of anchor rods in the tunnel at the same time to meet the different construction requirements of tunnels with different geological conditions. After the drilling and anchoring device performs the anchor rod support operation for the first time, it can rotate the swing arm and the anchor drill to support other anchor rods in the same row, thereby improving the operating efficiency of the anchor drill.
