Advantages of Spherical Hobs in Hydromill Cutting

  1. Cost Reduction: Implementing spherical hobs significantly lowers the costs associated with hydromill cutting in hard rock, enabling quicker project completion.

  2. Simplified Operations: Eliminating the need for precutting holes streamlines machinery requirements and construction processes.

  3. Extended Operating Time: The hob-tooth hydromill wheel allows for continuous operation for up to 100 hours, reducing the frequency of hydromill lifts and extending overall project timelines while lessening labor needs.

  4. Lower Maintenance Requirements: The hydromill module operates with reduced strain on the gearbox, enhancing efficiency and cutting down both maintenance time and costs.

  5. Minimal Environmental Disruption: This technology produces minimal ground disturbance, making it well-suited for projects near existing structures.

  6. Enhanced Cutting Deflection: The design improves deflection capabilities, making it effective for hydromill cutting in difficult rock formations.

  7. High Precision: Trenches can be maintained with vertical alignment accuracy of up to 1‰, ensuring superior quality in results.

  8. Fuel Efficiency: The system realizes over 20% in fuel savings, averaging 73L/h with a CAT C18 engine, promoting energy efficiency and environmental sustainability.

 

Cutting Wheels: Gearbox and Spherical Hobs

To operate effectively, a spherical hob must produce sufficient downforce, with each hob requiring at least 5 tons. In a wheel with a thickness of 1200mm, there are 54 hobs in total. Typically, around one-third—approximately 18 hobs—are actively involved in rock breaking, resulting in a required total pressure of no less than 90 tons. This necessitates that each gearbox can withstand 45 tons of pressure, underlining the need for strong radial load-bearing capabilities.

The hob functions as a rolling rock-breaker, which means it does not require high torque. For safety considerations, the gearbox is designed to handle a torque rating of 150 kNm. The output end features a tapered hexagonal structure, allowing for quick and efficient installation and removal of the cutting wheel.

The spherical hob employs two main types of fixed cutting tools: side hydromills and main cutting hydromills. Each trajectory line includes three side hydromills and two main cutting hydromills. Additionally, the design incorporates a flapper tooth in a roller configuration. This straightforward yet effective design provides enhanced force resistance compared to traditional machines, where the heavier flapper tooth structure often leads to accelerated wear of wear blocks and guide rings.

 

 

To ensure the effective operation of the spherical hob, it is essential to apply sufficient downforce, which is crucial for its success. This solution primarily involves adding a pressure mechanism between the cutting module body and the wheel, allowing for modifications to the existing module at a low cost. With the increase in downforce, the original gearbox's load-bearing capacity may become inadequate, necessitating the redesign of a larger gearbox. Due to constraints related to wheel size, the original shock absorber ring must be removed. Instead, this approach positions the shock-absorbing device between the motor reducer and the module.

 

 

The crowd device utilizes a support cylinder and an arm to hold the plate against the wall. One end of the pressurization cylinder is attached to the plate, while the other end connects to the module. As the pressurization cylinder contracts, it exerts downward pressure on the module. The oil circuits for both the support cylinder and the pressurization cylinder are integrated with the four oil circuits of the correcting plates located at the lower front and rear sides of the original module. This design eliminates the need for additional hydraulic circuits, making modifications relatively straightforward. The pressurizing mechanism leverages the support cylinder and arm to secure the plate against the diaphragm wall, with one end of the pressurization cylinder hinged to the support plate and the other to the module, providing necessary downward pressure as it contracts.
