Abstract
The invention provides a telescopic reversed loader pedestrian passage bridge, which belongs to the technical field of auxiliary equipment for fully mechanized coal mining face production fields; and the purpose is to mainly solve problems that no room for adjustment is available for the pedestrian passage bridges and the pedestrian passage bridges are deformed due to extrusion and cannot have a safety effect on pedestrians when big coal gangues are met because the pedestrian passage bridges are easy to mismatched at fixedly connecting parts in the prior art. The telescopic reversed loader pedestrian passage bridge comprises a handrail step, a supporting plate, a movable bridge plate, a hinging bridge plate, a reversed loader single-edge groove and a single-edge groove upper step; and the telescopic reversed loader pedestrian passage bridge is characterized in that a plurality of oil cylinders are arranged in the middle of the supporting plate vertically fixed on an upright base on one side of an end bracket group; oil cylinder bodies are hinged with the supporting plate; the end of a piston is hinged with the middle back part of the hinging bridge plate; one end of the hinging bridge plate is hinged with the top end of the supporting plate; guide rail grooves are formed on two sides of the hinging bridge plate in a length direction; and one end of the movable bridge plate is inserted into the guide rail grooves of the hinging bridge plate.
Description
Technical field
This invention patent belongs to fully-mechanized mining working production scene auxiliary equipment technical field, is specifically related to telescopic elevating conveyor pedestrian bridge.
Background technology
At present, what fully-mechanized mining working adopted is fixing rotary carrier aircraft pedestrian bridge, has following defect in actual production process:
Left and right two parts of a, pedestrian bridge are arranged on respectively the face end support group left and right sides, in process of production, due to the difference of face end support group left and right two parts walking step pitch, are easy to cause two parts dislocation of pedestrian bridge left and right, make troubles and danger to pedestrian;
B, because two parts of pedestrian bridge are to be fixedly welded on face end support group upright post base, while running into coarse coal spoil, do not have adjust leeway, can only, by the crimp of coarse coal spoil, can not play safe pedestrian's effect.
Summary of the invention
The object of the invention is cannot adjust for solving in prior art, cause easy damage, both sides easily misplace, and bring dangerous and inconvenience to pedestrian bridge, provide a kind of telescopic, retractable elevating conveyor pedestrian bridge is passed a bridge while not using.
This invention is to solve the problems of the technologies described above the technical scheme of taking to be:
Telescopic elevating conveyor pedestrian bridge, comprises ladder on handrail ladder, gripper shoe, movable bridge crossing plate, hinged bridge crossing plate, the monolateral groove of elevating conveyor, monolateral groove; It is characterized in that: described gripper shoe is vertically fixed on the upright post base of face end support group one side, gripper shoe middle part arranges some oil cylinders, and this cylinder block and gripper shoe are hinged, and piston termination and hinged bridge crossing plate postmedian are hinged; The top of described hinged bridge crossing plate one end and gripper shoe is hinged, above the both sides on hinged bridge crossing plate length direction, guide-track groove is set; Insert in the guide-track groove of hinged bridge crossing plate described movable bridge crossing plate one end.
The present invention compared with prior art, has following beneficial effect:
The present invention can avoid elevating conveyor pedestrian bridge by the crimp of coarse coal spoil, in addition because the movable bridge crossing plate of this device is to be overlapped on the monolateral groove of elevating conveyor, therefore effectively avoided because the dislocation that the difference of face end support group left and right two parts walking step pitch causes is made troubles to pedestrian and danger.
Accompanying drawing explanation
Fig. 1 is working state schematic representation of the present invention;
Fig. 2 is dead status of the present invention or the view while dodging coarse coal spoil.
In figure: 1-handrail ladder; The monolateral groove of 2-elevating conveyor; Ladder on 3-monolateral groove; 4-movable bridge crossing plate; 5-hinged bridge crossing plate; 6-oil cylinder; 7-gripper shoe.
The specific embodiment
As shown in Figure 1, telescopic elevating conveyor pedestrian bridge, comprises ladder 3 on handrail ladder 1, gripper shoe 7, movable bridge crossing plate 4, hinged bridge crossing plate 5, the monolateral groove 2 of elevating conveyor, monolateral groove; Be characterized in: described gripper shoe 7 is vertically fixed on the upright post base of face end support group one side, gripper shoe middle part arranges some oil cylinders 6, and this oil cylinder piston termination and gripper shoe are hinged, and cylinder body and hinged bridge crossing plate postmedian are hinged; The top of described hinged bridge crossing plate 5 one end and gripper shoe 7 is hinged, above the both sides on hinged bridge crossing plate 5 length directions, guide-track groove is set; Insert in the guide-track groove of hinged bridge crossing plate described movable bridge crossing plate 4 one end.
Using method and operating principle:
When this invention patent is used, on push panel, put bridge button, piston-retraction oil cylinder drives hinged bridge crossing plate to set level, staff on handrail ladder to hinged bridge crossing plate, movable bridge crossing plate is released and is overlapped on the monolateral groove of elevating conveyor, get off via ladder on monolateral groove; In the time stopping using, can rise bridge button oil cylinder piston is stretched out pressing, make the withered plate of hinged mistake upwards turn an angle, effectively avoid coarse coal spoil to the extruding of passing a bridge.
