Description
Technical Field
The utility model belongs to the technical field of the current equipment of mine, especially, relate to a pedestrian's gap bridge of adjustable height in pit.
Background
A rubber belt conveyor is generally adopted to transport coal in a coal mine underground tunneling working face or a coal face transportation crossheading, and pipelines, cables and the like are generally arranged on the inner side of a belt and need to be maintained and overhauled periodically, so that pedestrians need to pass a bridge above a belt frame. Traditional pedestrian crosses a bridge and adopts fixedly, and highly can not adjust, when the tunnel has the slope, crosses a bridge and just is difficult to guarantee the bridge floor level, causes pedestrian to cross a bridge potential safety hazard. If weld into high-low leg according to the tunnel slope with passing the bridge, when the tunnel slope is inconsistent, can cause the bridge to be difficult to used repeatedly.
Disclosure of Invention
In view of this, the utility model aims at providing a pedestrian's gap bridge of adjustable height in pit, when aiming at solving the underworkings and having the slope, the gap bridge is difficult to guarantee the horizontally defect of bridge floor.
In order to achieve the purpose, the technical scheme is as follows:
the utility model provides a pedestrian that adjustable height passes a bridge in pit, includes bridge floor, cat ladder and bearing structure, it sets up at a plurality of to hold up the bridge floor bearing structure is last, the both sides of holding up the bridge floor are equipped with the cat ladder, bearing structure includes supporting leg, lower supporting leg and fixed buckle, the upper end and the bridge floor of going up the supporting leg are connected, the lower extreme of going up the supporting leg with the upper end suit of lower supporting leg is connected, the bolt preformed hole of the radial direction of a plurality of is seted up on the suit connecting portion of going up supporting leg and lower supporting leg to pass the bolt preformed hole through fixing bolt and realize going up the connection of supporting leg and under bracing, be provided with fixed buckle on the lower extreme of lower supporting leg.
Furthermore, the lower supporting leg is connected with the fixed buckle in a hinged mode.
Furthermore, handrails are arranged on two sides of the bridge floor.
The utility model discloses a have beneficial effect to be: the utility model relates to a simply, rationally, practical, can highly satisfy the demand of different tunnel slopes through the regulation supporting leg, can guarantee that the bridge floor is steady all the time, stability is high, and easy installation has guaranteed staff's security, has improved the security.
