The invention discloses a bearing connecting girder used for a downhole tracked unloading point and the downhole tracked unloading point. The bearing connecting girder comprises a girder body, a bearing tray plate, a first reinforced rib, a fixed tray plate, and a second reinforced rib, wherein the girder body stretches in the left-right direction, and the left part of the girder body forms a fixed part, and the right part forms a cantilever part, the supporting tray plate is connected with a cantilever part of the girder body; the first reinforced rib is arranged below the supporting tray plate, and is connected with the supporting tray plate and the cantilever part respectively; the fixed tray plate is connected to the fixed part of the girder body; the second reinforced rib is connected with the fixed tray plate and the girder body respectively, and second reinforced rib is one reinforced rib or at least two reinforced ribs which are arranged at intervals in a left-to-right mode. According to the bearing connecting girder used for the downhole tracked unloading point and the downhole tracked unloading point, the fixed part and the cantilever part of the girder body form a lever structure; through the arrangement of the first reinforced rib and the second reinforced rib on the girder body, the strength of the bearing connecting girder can be improved, and the shock resistance of the bearing connecting girder is improved.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a supporting and connecting steel beam for an underground rail unloading station and an underground rail unloading station provided with the above-mentioned supporting and connecting steel beam for an underground rail unloading station. Background technique [0002] In the related technology, in the underground rail unloading station of large-scale mines, in order to widen the unloading space, the unloading side rollers are installed with steel beams. Concrete cantilever beams are used as supporting beams, and wear-resistant steel plates are installed on the surface of the cantilever beams to prevent impact damage during unloading. However, the construction process of reinforced concrete supporting beams in underground rail unloading stations of large mines is complicated, the construction period is long, and it will be impacted by the ore (waste) rocks being unloaded.
