Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel over-excavation controlled static excavation excavator. Background Art

[0002] Static blasting technology is a new technology for crushing or cutting rocks and concrete. Compared with traditional explosive blasting, it has the characteristics of no noise, no vibration, no flying rocks and no blasting smoke pollution. It is mainly used in concrete demolition projects and stone material mining with high environmental protection requirements. In recent years, it has also been used in some tunnel excavation construction. Tunnel over-excavation control is an important link in tunnel construction, which is related to the safety, quality and cost of tunnel construction. The traditional static tunnel excavation method has the phenomenon of over-excavation, which not only increases the construction cost, but also may affect the stability of the tunnel. Therefore, it is of great practical significance to develop a static excavation machine that can effectively control tunnel over-excavation.

[0003] The Chinese patent with the authorization announcement number CN202611693U discloses a composite cantilever tunnel boring machine, including a tunnel boring machine body, a tunneling mechanism, a traveling mechanism, a hydraulic system, an electrical system, a conveying mechanism and a dust removal system. The tunneling mechanism includes a cutting head and a cutting arm. The cutting head is located at the top of the cutting arm, and the lower part of the cutting arm is movably fixed on the tunnel boring machine body; the traveling mechanism includes a power machine and crawlers located on both sides below the tunnel boring machine body; the upper part of the cutting arm of the tunnel boring mechanism is provided with an impact crushing mechanism, and the impact crushing mechanism includes a hydraulic cylinder and a breaker located at the top of the hydraulic cylinder. The above-mentioned tunnel boring machine performs smooth blasting through the impact crushing mechanism, and is assisted by the tunneling mechanism for mechanized construction, which can achieve efficient excavation and lining of the tunnel, and control the scope and size of over-excavation and over-consumption.

[0004] The above-mentioned existing technical solutions have the following defects: the operator of the tunnel boring machine cannot accurately control the tunnel forming due to the visual blind spot, and there may even be the situation that the cutting head cuts the shovel plate. Therefore, during normal operation, it is generally necessary to arrange a commander to the right front side of the tunnel boring machine to direct the operator to operate and help the operator solve the visual blind spot. This kind of excavation information collection of the excavator has certain safety issues, the operator cannot quickly obtain the operation information, and the information delay is poor. Therefore, it is necessary to set up an image acquisition and processor near the cutting head of the tunnel boring machine to monitor the excavation information in time and facilitate the operator to adjust the excavation direction in time. Utility Model Content

[0005] The problem to be solved by the present utility model is to provide a tunnel over-excavation control static excavation tunneling machine in view of the above deficiencies in the prior art. By installing an image acquisition and processor on the cutting arm of the tunneling machine, and the position of the image acquisition and processor is adjustable, it has the advantage of real-time monitoring of the static excavation situation of the tunnel, thereby assisting the operator to effectively control the over-excavation phenomenon and improving the construction safety and efficiency.

[0006] The above utility model objective of the present utility model is achieved through the following technical solutions:
