Automatic digging mechanism of intelligent construction tunneling machine

Abstract

The invention discloses an automatic digging mechanism of an intelligent construction tunneling machine. The automatic digging mechanism comprises a first tunneling mechanism and a second tunneling mechanism, wherein the first tunneling mechanism is arranged on the second tunneling mechanism, a ring of synchronously telescopic and rotating first drill bits are arranged on the first tunneling mechanism, a first top pressing shaft is arranged at an end of each first drill bit, a first chain wheel is arranged at the end of each first top pressing shaft, a ring of synchronously telescopic and rotating second drill bits are arranged on the second tunneling mechanism, a fourth top pressing shaft is arranged at the end of each second drill bit, and a second chain disc is arranged at the end of each fourth top pressing shaft. The first drill bits and the second drill bits drill holes on a wall, so that the hole size on the wall can be unified, the problem of different hole sizes caused by manual drilling can be avoided, and the digging efficiency is improved greatly.

Description

technical field [0001] The invention relates to a tunnel machine, in particular to an automatic excavating mechanism of an intelligent construction tunnel machine, in particular to an intelligent construction tunnel machine capable of automatic drilling. Background technique [0002] With the continuous increase of road construction, the continuous development of road machinery and equipment has been further promoted. Road machinery can be used to quickly build roads. In the process of tunnel construction, large-scale tunnel machinery will be used to excavate tunnels. Large-scale Tunnel machinery includes equipment such as shield machines, which can realize automatic hole-digging operations. Although the shield machine can realize hole-digging operations, the shield machine can only be used when the length of the tunnel is long. It can be used, but for tunnels with a short distance, the shield machine cannot be used for excavation operations. When the tunnel distance is shor...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, an automatic excavating mechanism for an intelligent construction tunnel machine is provided. The first drilling module and the second drilling module are respectively provided with a self-rotating first drill bit and a second drill bit in the present invention. and the second drill bit can drill holes on the wall of the tunnel, thereby avoiding the problem of inefficiency caused by manual drilling one by one, greatly improving the drilling efficiency, and at the same time, the percussion mechanism can be used to correct the remaining holes left by the drilling The stones are knocked to complete the drilling work, which greatly improves the drilling efficiency, and at the same time can make the drilled holes have the same diameter, which can facilitate the input of hydraulic modules, thereby improving the excavation efficiency of the tunnel
