Embodiment Construction

[0022] Such as figure 1 As shown, the present invention includes a bolt 1, a nut 2, a backing plate 3, a top bracket 4, a chute guide rail 5, a connecting body 6, a hob seat 7, a disc hob 8, a guide column 9, a column 11, and an earth bin 10. Vertical hydraulic cylinder 12, hydraulic motor 20, soil bin support seat 13, slewing bearing 14, pinion gear 15, base 17 and foundation frame 18, etc. The slewing support 14 is used between the soil silo support seat 13 of the fixed soil silo 10 and the rectangular base 17 fixed on the foundation frame 18, and is driven to rotate synchronously by two hydraulic motors 20, and the hydraulic motor 20 is installed on the motor mounting frame 16. The motor mounting frame is installed on the foundation frame 18 . The inner ring of the slewing bearing 14 is fixed on the rectangular base 15, and the outer ring is connected with the soil bin support seat 13. The soil bin 10 has a flange, and four evenly distributed vertical hydraulic cylinders ...

Abstract

The invention relates to a position adjustable multi-hob rotary cutting test-bench. The soil warehouse base fixed on the soil warehouse and a rectangular base fixed on the ground frame are supported by a looping support and looped by two hydraulic motors synchronously. Periphery of the soil warehouse is provided with flanges, which is provided with four guiding pillars evenly and four hydraulic cylinders; the four hydraulic cylinders driven synchronous vertical position into the soil to the campaign from the four columns to orientation and direction of torque transmission. 6 shelves uniform foundation column layout, fixed a column to open the top 4 at the top ring groove of the frame, forming a rectangular frame; connected at the top of the bottom bracket has three slide rail and the knife block, plate hob installed in the Seat knife. Using IPC test, data acquisition cards, the pressure of the flow velocity sensor, dynamic strain gauge, high-speed digital camera system on the cutting process of geotechnical monitoring. The test-bench is mainly used for the multi-hob and rotary cutting of rock mechanical properties of the relevant test.

Description

technical field [0001] The invention relates to a cutting test platform with multiple hobs for shield tunneling used in the field of tunnel engineering, in particular to a rotary cutting test platform with adjustable positions of disc-shaped hobs. Background technique [0002] The 21st century is the century of rapid development of China's engineering construction. In the new century, the development of large-scale projects such as water conservancy, energy, and transportation has become the focus of my country's economic construction. With the large-scale construction of my country's infrastructure and the implementation of the western development strategy, there will be a large number of long and large tunnels to be built in railways, highways, large and medium-sized hydropower stations, and projects such as South-to-North Water Diversion. Projects (sewage pipes, water pipes), cross-river tunnels are also increasing. Due to its own advantages, the shield tunneling method h...
