Problems solved by technology

However, the traditional mechanical clamping rails and corbels are inconvenient to disassemble and assemble, and have low stability, which is easy to cause personal injury and construction failure. The counter force provided by the welded steel structure will greatly increase the labor force and reduce the stepping speed

Abstract

The invention provides an open type automatic inclined shaft rail clamping stepping device of a rock tunnel boring machine. The tunnel boring machine is provided with a main tunnel boring machine (TBM) body. A bottom shield is arranged below the main TBM body. The automatic inclined shaft rail clamping stepping device comprises a sliding rail plate, a stepping oil cylinder and a rail clamping device. The sliding rail plate is arranged below the bottom shield. The rear portion of the sliding rail plate is connected with the rail clamping device through the stepping oil cylinder. The open type automatic inclined shaft rail clamping stepping device of the rock tunnel boring machine is designed based on the sliding rail type stepping mode, stepping on the flat slope section can be achieved, and meanwhile stepping requirements of large gradient (downhill) which is larger than 10 degrees can be met; the main TBM body does need to be jacked, and construction safety is high; and in addition, the rail clamping device is controlled by a hydraulic pipeline system, operation is easy, and the stability is high.

Description

technical field [0001] The invention belongs to a heading machine stepping device, in particular to an automatic rail-clamping stepping device suitable for an open rock tunnel boring machine (full-section rock boring machine) inclined shaft. Background technique [0002] Traditional open rock tunnel boring machine stepping devices are divided into tunneling type, leapfrog type, rail type, slide rail type, skateboard type, etc. Due to the influence of engineering and equipment conditions, tunneling type and leapfrog type are only used in specific projects. It is selected under the conditions of the equipment, the cost of the rail type is high, and it is inconvenient to disassemble and assemble. The sliding plate type and the slide rail type have become the most widely used stepping methods, and are favored by the construction parties and owners of the roadheaders. [0003] Skateboard stepping method is to install a small slide plate under the bottom shield of the tunneling ma...
