R37 coal mine roadway repair machine is a high-efficiency equipment specially designed for heavy-duty roadway repair in coal mine. 6.5T machine weight with 5100mm×1200mm×2150mm (1260mm without roof) solid figure, taking into account the accessibility of the underground and the stability of the operation. 37kw mounted power drive, the rated pressure of the hydraulic system up to 21.5/31.5Mpa, bucket capacity 0.21m³, maximum bucket digging force 37KN, for the safe operation of the coal mine roadway. Driven by 37kw installed power, the rated pressure of hydraulic system reaches 21.5/31.5Mpa, the bucket capacity is 0.21m³, and the maximum digging force of the bucket is 37KN. Together with the crushing device with 600j impact energy, the machine can efficiently complete the heavy-duty tasks of roadway support, gangue clearing, shaping, etc., which provides the core guarantee for the safe operation of coal roadway.
Usage Scenarios
Variety mining face roadway repair: in the variety mining face, such as the upper and lower tunnels and other heavy-duty roadways, 1200mm width can be adapted to the bracket spacing, 300mm track plate width and ≤ 0.1mpa ground pressure, to avoid crushing the roadway floor. 37KN bucket digging force can quickly clean up the collapsed gangue, the three-section arm structure to achieve ≥ 5250mm digging width, with 68mm brazing specification of the crushing device can be used to With the crushing device of 68mm brazing tool, it can break hard rock and concrete support, clearing the obstacles for the advancement of comprehensive mining equipment.
Deep roadway maintenance: Facing the deformation repair of deep high-stress roadways, the R37's 4800mm digging height can deal with the problem of roadway roof subsidence, and the 2450mm digging depth can repair the bottom slab bulge. The integrated hydraulic motor reducer-driven tracks provide stable travel on 14° slopes, and the 26m/min travel speed allows for fast travel to and from the working surface, enhancing the efficiency of deep roadway maintenance.
Roadway ganging and undercutting: When it is necessary to gang or undercut the roadway, the 1200mm×320mm push shovel can level the working surface, and the maximum pushing depth of 200mm can accurately control the undercutting amount. The flexible rotation of the three-section arm and the 360° working range can accurately trim the roadway contour to meet the needs of roadway section expansion and ensure the safety of transportation and ventilation.
