Description

Technical Field

[0001] The invention relates to the technical field of cavern construction, and in particular to a cavern construction device and system. Background Art

[0002] Cavern excavation refers to the process of loosening, crushing, excavating and transporting the soil or rock when building a tunnel. It is widely used in water diversion, drainage, diversion, transportation and other tunnel construction in water conservancy projects.

[0003] The main methods of cave excavation are shield tunneling and drilling and blasting. The drilling and blasting method is to drill a number of holes of appropriate depth on the rock blasting surface, load explosives and detonate them, thereby breaking the rock and completing the excavation of the tunnel. The drilling process in the drilling and blasting method mainly uses a pneumatic rock drill (hand pneumatic drill). While the drill rod is advancing, the operator needs to adjust the height of the pneumatic support legs and control the shaking of the hand pneumatic drill. Especially when the hole depth is shallow, the hand pneumatic drill shakes more severely, and the operator needs to spend a lot of force to control the hand pneumatic drill from turning forward, backward, left and right, which not only consumes a lot of physical strength of the operator, but also poses a safety hazard. Summary of the invention

[0006] Beneficial effects: The present invention detachably mounts the rock drill in a fastening assembly on the mounting frame. The fastening assembly clamps and fixes the rock drill, thereby ensuring that the rock drill is stably mounted on the mounting frame during construction, reducing the vibration amplitude of the rock drill during operation. The operator only needs to control the forward and backward movement of the rock drill, which makes it easy for the operator to control and operate the rock drill, thereby improving construction efficiency and safety.

[0007] In an optional embodiment, the fastening assembly includes a first mounting portion and a second mounting portion, the first mounting portion is fixed on the mounting frame, the second mounting portion is movably connected to the first mounting portion, the first mounting portion and the second mounting portion enclose an installation cavity, the installation cavity is suitable for installing a rock drill, and the first mounting portion and the second mounting portion have a fastened state for installing the rock drill and a loosened state for disassembling the rock drill.

[0008] Beneficial effects: The present invention adopts a method of active connection between the first mounting part and the second mounting part, which is convenient for disassembly, assembly and maintenance of the rock drill. When the rock drill is in a fastened state and installed in the mounting cavity, the first mounting part and the second mounting part can limit the rock drill, reduce the shaking of the rock drill during operation, and is more conducive to the operator's operation and control. When the rock drill is in a loosened state, the operator can remove the rock drill for maintenance or replacement. It has the advantages of simple structure and convenient operation.

[0009] In an optional embodiment, the first mounting portion is in a concave arc shape, the second mounting portion is in a convex arc shape, and the mounting cavity is circular.

[0010] Beneficial effect: The present invention sets the installation cavity to be circular to adapt to the shape of the rock drill, so that the rock drill can be installed more stably in the installation cavity.

It has a simple structure and a firm snap-on connection, which can ensure that the rock drill is firmly installed in the mounting cavity when working.

[0014] In an optional embodiment, the cavern construction device further includes a protective member, which is disposed on the trolley and faces one side of the construction surface.

[0015] Beneficial effect: The present invention provides a protective piece on the trolley facing the construction surface to block dust generated during construction and reduce the damage to the health of workers caused by mud and sand carried by the back-blown airflow.

[0016] In an optional embodiment, the trolley includes at least two vertically arranged columns and at least one horizontally arranged crossbar, the crossbar is connected to the columns, and the mounting frame is detachably mounted on the columns.

[0017] Beneficial effects: The present invention can detachably mount the mounting frame on the column.
