Description

Technical Field

[0001] The utility model relates to the technical field of tunnel rock crushing, and more specifically, to a rock crushing device for tunnel construction. Background Art

[0002] Tunnels are engineering buildings buried in the ground. They are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. No matter what kind of tunnel it is, it needs to face the obstruction of hard rocks underground during construction. Today's tunnel construction is mostly carried out inside the mountain, which makes it impossible to use blasting to break the rocks. Otherwise, once the blasting occurs, it is easy to cause damage to personnel and construction tunnels. Therefore, at this stage, static crushing methods are mostly used to break rocks in tunnels, and static crushing mostly uses rock splitting bars to break rocks. When using a rock splitting bar, you need to drill a hole first, then send the rock splitting bar into the hole, and then break the rock through the rock splitting bar.

[0003] The existing rock crushing device for tunnel construction will generate a large amount of dust in the process of drilling rocks. The dust floats inside the tunnel, affecting the health of people in the tunnel. After drilling the hole, there will be rock cores inside the drill barrel, which is not convenient to take out the rock cores inside the drill barrel. In addition, since it is necessary to drill a hole with a drill barrel first, and then insert a rock splitting rod into the drill hole to crush the rock, it is not convenient to store the drill barrel and the rock splitting rod. The rock splitting rods of the existing rock crushing device for tunnel construction are all separately provided. In the process of rock crushing, people need to lift the rock splitting rod and insert it into the drill hole. Since the rock splitting rod is heavy, it requires a lot of manpower, which reduces the practicability of its use, and there is a certain danger in the lifting process. Utility Model Content
