Description

Technical Field

[0001] The utility model relates to the technical field of underground coal mine conveyors, in particular to a gantry device for conveyors. Background Art

[0002] Telescopic conveyors are mostly used for transportation in underground coal mines. Telescopic conveyors have belt storage devices, tensioning devices and belt winding devices. During normal design, in order to ensure the design strength, the belt storage bin, tensioning part and belt winding part of the telescopic conveyor are connected in sequence into one. However, when mining coal underground, it is possible that one tunnel intersects with another tunnel. When the conveyor is placed in one of the tunnels, it will cross the intersection with the other tunnel, affecting the normal use of the other tunnel, such as affecting the passage of people and vehicles in the other tunnel, or affecting the layout and installation of the second conveyor in the other tunnel.

[0003] Traditional solutions typically involve raising the conveyor belt at the intersection of the laneways to allow the conveyor belt to avoid the laneway intersection. For example, patent application CN110371584A discloses an arch-bridge-type body belt conveyor. This arch-bridge structure is designed at the intersection of the auxiliary air inlet stone gate and the auxiliary inlet laneway to increase the effective space at the laneway intersection and address the difficulty of transport operations at the laneway intersection. However, this arch-bridge structure is only suitable for relatively narrow laneway intersections. When the laneway is wide, if it continues to span the laneway, it will easily affect the rigidity of the conveyor. If a leg is added between the two high-type legs C, it will occupy laneway space, affecting the layout and installation of vehicles or other conveyors. Therefore, it has limitations. In particular, the arch-bridge structure of the conveyor raises the height of the upper conveyor belt at the laneway intersection, giving it a certain slope. This makes the upper conveyor belt at the intersection of coal mines dangerous when transporting coal, affecting the normal operation of the conveyor. Utility Model Content
