Description

Technical Field

[0001] The invention relates to a large electro-hydraulic trolley device which can be used for tunnel excavation, rock drilling, anchor drilling and steel arch installation. The device belongs to the field of special equipment for tunnel excavation, blasting, rock drilling and early support construction. Background Art

[0002] A trolley is a general term for a structure used in tunnel construction. Tunnel excavation begins with face rock drilling and blasting. After mucking, anchor rods are drilled and installed, followed by steel arch support and shotcrete spraying. Currently, rock drilling is mostly done manually with air guns or multi-arm chisels (2-3 arms), requiring multiple positioning and securing of the trolley. Steel arch installation is often done manually using simple trolleys, which is slow. A large electro-hydraulic trolley system, universally applicable for full-face tunnel excavation, blasting, drilling, anchor rod drilling, and steel arch installation, could significantly improve construction speed and ease of operation and installation.

[0003] The trolley has motorized travel, automatic level holding system, one-time fixed coordinate positioning drilling rig, remote control actuator, and construction vehicles and equipment inside the tunnel can pass through the gantry.

[0004] Two rows of lifting beams are hung on the front door frame of the trolley, and 2-3 pairs of hydraulic rock drilling rigs are installed on each row of beams.

[0005] The crossbeam can be raised and lowered on the gantry to adjust the cable fixation; the hydraulic rock drill can be moved left and right on the crossbeam to adjust the cable fixation; each hydraulic rock drill can adjust the cable fixation at axial and radial angles to cover the drilling of blasting holes at any angle in the entire axial section of the tunnel and the drilling of anchor holes at any angle in the entire radial direction; the hydraulic excavation pneumatic feed water presses out the rock slag ash from the drill hole.

[0006] The trolley is equipped with a steel arch frame for installing the small trolley and has the function of electromechanical and hydraulic three-dimensional movement adjustment and rope fixing; a telescopic boom is provided for lifting and clamping the steel arch frame.

[0007] Small back-held intelligent remote control actuator; displays various control information data. Currently, there are no such trolleys or similar products in China. Summary of the Invention
