Description

Technical Field

[0001] The utility model relates to the technical field of tunneling machines, in particular to a tunneling machine with a fast drill bit replacement function. Background Art

[0002] A roadheader is a large-scale engineering machinery used for digging tunnels, mines or other underground spaces underground. They are widely used in mining, tunnel construction, subway construction and other fields. Publication No. CN208310787U discloses a roadheader that can operate normally and stably in a large slope environment, including a machine body, a walking mechanism is arranged at the lower part of the machine body, a cutting mechanism is arranged at the front part of the machine body, and a shovel mechanism protruding forward is arranged on the machine body below the cutting mechanism. After the cutting mechanism cuts the material, the shovel mechanism collects the material and transports it to a conveyor located behind the machine body for output. The cutting mechanism includes a milling head, which is hinged to the machine body through a bendable multi-section arm. The driving mechanism drives the milling head to swing in the horizontal plane and rotate in the vertical plane, and the milling head can be in a position in contact with the ground. In the above scheme, the milling head can be in a position in contact with the ground and supported on the ground, and then the machine body is pushed forward and backward by the thrust of the cylinder. Due to the supporting effect of the milling head, the contact area between the tunnel boring machine and the ground is increased, so that the tunnel boring machine can work normally in an environment with a large slope. Although this product has good stability, it is inconvenient to replace the position of the drill bit. When the drill bit is disassembled and installed, there is no supporting auxiliary structure. The position of the drill bit needs to be adjusted to a suitable position for installation by external force, which reduces the installation efficiency and poor practicality. It needs to be improved.
