Problems solved by technology

[0004] In order to solve the problem of encountering boulders in front of the underwater tunnel in the existing technology, it is not uncommon to encounter them, and it is difficult to deal with them quickly, which affects the efficiency and safety of tunnel construction. Currently, the conventional boulder treatment methods mainly include underwater Deep hole blasting and in-hole blasting, but these methods have problems of high cost, high risk factor, and long construction period. The purpose of this invention is to propose a laser device for cutting the boulder in front of the tunnel

Abstract

The invention discloses a laser device for cutting solitary stones in front of a tunnel, including a shield case. A side plate is fixedly connected inside the shield case. A cutter head is arranged onone side of the side plate. Multiple placement slots are arranged in one side of the cutter head away from the side plate. Cutter knives are arranged in the placement slots respectively. A laser mounting bracket is fixed in the middle of the cutter head. A protective cover is fixed on the other side of the side plate. A second gear is arranged between the protective cover and the side plate. A rotating shaft is fixed in the center of one side of the second gear. One end of the rotating shaft runs through the side plate and fixedly sleeves the center of the cutter head. The rotating shaft is sleeved with a sealing ring in a sliding manner. The sealing ring is fixedly connected with one side of the side plate near the cutter head. Two first servo motors are symmetrically arranged on one side of the protective cover away from the side plate. The laser device for cutting solitary stones in front of a tunnel is simple in structure and convenient to operate, can freely control the work of any laser, and is easy to disassemble, install and maintain.

Description

technical field [0001] The invention relates to the technical field of tunnel excavator equipment, in particular to a laser device for cutting boulders in front of tunnels. Background technique [0002] With the development of the economy, the country has gradually increased the construction of infrastructure, especially in recent years, the construction of cross-sea and cross-sea tunnels has gradually increased. In the process of tunnel construction, shield machines are often used to speed up work efficiency. Shield machines The construction method is that the tunnel boring machine constructs the "shield" of the tunnel while digging, which is different from the open construction method. [0003] However, there is an increasing demand for the construction of existing cross-river and sea-crossing tunnels. However, during the construction of underwater tunnels, it is not uncommon to encounter boulders ahead, and it is difficult to deal with them quickly, which affects the effi...
