Description

Technical Field

[0001] The utility model relates to an experimental device for a hob cutter holder and a water jet cutter holder with freely adjustable angles, belonging to the technical field of tunnel construction. Background Art

[0002] The shield machine is a complex, large-scale tunnel construction equipment that integrates mechanical, electrical, hydraulic, fluid, optical, sensor, and information technology. The cutterhead is one of its core components, and the cutters are a crucial component, serving as the steel teeth of the shield machine during tunneling. Studying and analyzing their stress conditions is crucial for improving construction safety and enhancing design theory. The cutters on the cutterhead are divided into center cutters, front cutters, and edge cutters. The center and front cutters are installed parallel to the shield machine's axis of excavation, while the edge cutters are installed at a specific angle relative to the axis of excavation. Simulation tests require adjusting the cutters' inclination angles to simulate the conditions. This typically requires fabricating numerous cutterheads with varying inclinations. For example, a six-meter-class cutterhead has twelve edge cutters with eleven different inclination angles. To meet these requirements, these cutterheads would require fabricating eleven different cutterheads, increasing project costs and impacting operational efficiency. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a hob tool holder and a water jet tool holder experimental device with freely adjustable angles in view of the defects in the prior art.

[0004] To solve this technical problem, the present invention provides an experimental device for a hob cutter holder and a water jet cutter holder with freely adjustable angles, comprising a hob cutter holder body, a water jet cutter holder, a hob cutter angle adjustment block and a fixing bolt, wherein the hob cutter holder body is mounted on a testing machine, and the water jet cutter holder is mounted on the hob cutter holder body; two T-slots are provided on the front portion of the hob cutter holder body, and built-in nuts are provided in the T-slots; the water jet cutter holder comprises a water jet cutter holder connecting plate and a high-pressure water jet cutter, and an arc-shaped mounting groove is provided on the water jet cutter holder connecting plate, and the fixing bolt is placed in the arc-shaped mounting groove and is locked and fixed with the built-in nut of the T-slot, and can adjust the angle and height distance of the water jet cutter holder relative to the hob cutter.

[0005] A mounting surface is provided on the top of the hob cutter holder body, and a hob cutter angle adjustment block is provided between the mounting surface of the hob cutter holder body and the testing machine.

[0006] The hob angle adjustment block is a wedge-shaped structure and can be of various specifications to achieve different hob inclination angles.

[0007] The high-pressure water jet cutting tool consists of a tearing knife and a water cutting head.

[0008] The hob cutter holder body and the hob cutter angle adjustment block are mounted on the testing machine via the hob cutter holder fixing bolts.

[0009] Beneficial Effects: This utility model adds a cutter angle adjustment block to the existing cutter holder, enabling free adjustment of different cutter angles, significantly reducing project costs. Simultaneously, adding a water jet holder to the angle-adjustable cutter holder allows for simultaneous testing of the water jet and cutter, allowing for experimental analysis of the relative positional relationship between the cutter and the water jet. This provides first-hand experimental data for preliminary theoretical research on water jet-assisted rock breaking with cutters, providing important theoretical support for the project's implementation.
