Description

Technical Field

[0001] The utility model relates to the technical field of mining trailers, in particular to a platform extension device for a mining TBM trailer. Background Art

[0002] A mining TBM, or tunnel boring machine, is a large-scale mechanical equipment used for full-section rock and soil excavation in mine tunnels and underground projects. It integrates mechanical, electronic, hydraulic and laser guidance technologies, and can excavate tunnels efficiently and continuously. Compared with traditional drilling and blasting excavation methods, it has many advantages such as fast excavation speed, safe construction and less impact on the surrounding environment. The mining TBM has high excavation efficiency. The trailer moves forward with the main machine, and one trailer is equipped with two drilling rigs. The mining TBM trailer is an important supporting part of the TBM equipment. It is mainly used to transport various materials, equipment accessories and slag during the TBM construction process. It plays a key role in ensuring material transportation and equipment support in the entire mine tunnel excavation work.

[0003] When a mining TBM is excavating a rock tunnel in a coal mine, the trailer has a support function and can support the tunnel during transportation, achieving parallel support and transportation, improving excavation efficiency, enhancing construction safety, and optimizing construction processes and coordination. There is a large gap between the two sides of the support platform and the tunnel wall to prevent interference between the trailer and the tunnel wall during excavation. However, the gap between the two sides of the trailer and the tunnel wall causes the support workers to face the risk of falling when supporting on both sides of the trailer. In order to reduce the risk of falling, some additional safety measures are often required, such as installing guardrails and safety ropes. However, the installation and removal of these measures take time, which will affect the use of support tools and the handling of materials, further reducing work efficiency. Utility Model Content
