Abstract

The embodiment of the invention discloses a tunnel puncher which comprises a track driving device, a supporting mechanism, a lifting operation mechanism and a drilling mechanism. The track driving device comprises a track platform, driving wheels are mounted below the track platform, and a driving device for driving the driving wheels is mounted above the track platform. The supporting mechanism comprises a first support, a second support and a clamping support, the lower end of the first support is hinged to the rail platform, the upper end of the first support is hinged to the upper end of the second support, and the lower end of the second support is installed on the clamping mechanism at the upper end of the clamping support. The lifting operation mechanism comprises a chain wheel device installed on the first support, and an operation platform moving along with the chain wheel device is fixedly installed on the chain wheel device. The drilling mechanism comprises a fine adjustmentdevice installed on the operation platform, and a drilling machine is installed on the fine adjustment device, so that the narrow tunnel space is effectively utilized, and the drilling efficiency isimproved. The risk of manual climbing operation is reduced, and the drilling accuracy is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of railway maintenance equipment, in particular to a tunnel puncher. Background technique [0002] Since my country's railway system is an independent system, in order to ensure the personal safety of passengers traveling on the railway, we must abide by the rules and regulations of railway driving, and it is forbidden to occupy the time of railway driving for railway construction. Therefore, it is necessary for the railway system to carefully arrange and adjust the train running time, and to approve the construction blockade time (the blockage time is generally about 100 minutes). The construction unit can only carry out the construction work on the railway business line after the railway dispatching permit. The time left for the construction unit is limited and the tasks are heavy. [0003] The construction unit must sign an agreement before the construction of the railway busin...
