| titleOfInvention | Hydraulic support and tamping mechanism |
| abstract | The invention relates to a walking mine roof support for mining, in particular to a hydraulic support and a tamping mechanism. The tamping mechanism is including the ramming roof beam that can stretch out and draw back the setting from beginning to end, and the ramming roof beam includes fixed beam section and the walking beam section of arranging along ramming roof beam length direction, and fixed beam section is used for articulating at the base rear portion, and the walking beam section is provided with at least one, and two adjacent beam sections direction sliding fit in fixed beam section and the walking beam section, and connect in order to form scalable beam section through hydraulic jack between the two adjacent beam sections, at least one in fixed beam section and the walking beam section is hollow out construction to supply the coal gangue to pass from the top down. In the tamping mechanism of the hydraulic support, at least one of the fixed beam section and the movable beam section is of a hollow structure so as to allow coal gangue to pass through from top to bottom, so that the coal gangue accumulated above the tamping mechanism can be reduced, the normal work of the tamping mechanism is facilitated, and the working efficiency of the tamping mechanism and the hydraulic support can be improved. |
