Abstract
The utility model discloses a hydraulic support telescopic top beam with a face guard mechanism, comprising a front beam, a telescopic beam, a face guard and a telescopic jack, wherein, the telescopic beam is inserted in the box-shaped cavity body of the front beam in a sliding mode, the face guard is hinged to the front end of the telescopic beam, and the telescopic jack is arranged between the front beam and the telescopic beam. The middle position of the lower surface of the front beam is provided with a hollow region, a face guard jack is arranged in the hollow region, and a piston rod of the face guard jack is hinged with the face guard. The utility model is characterized in that the face guard is connected with the front beam by the face guard jack, so a bracket is saved, and the thickness and the quality of the telescopic beam are reduced; the cylinder body of the face guard jack is arranged in the hollow region arranged on the middle position of the lower surface of the front beam, so the structure of the whole beam body is compact, and the over machine height is increased; and at the same time the ventilation area is also increased.
Description
Technical field
The utility model relates to mine hydraulic bracket, relates in particular to the flexible back timber of hydraulic support of band side protecting mechanism.
Background technology
The extensible canopy hydraulic support is the main support apparatus of fully-mechanized mining working, and in the coal seam fragmentation, easily field with "nine squares" when exploitation of wall caving takes place, employed extensible canopy hydraulic support all has side protecting mechanism.Be connected by the wall supporting jack between the present employed extensible canopy hydraulic support, its face guard and extensible canopy and be provided with joist, make that the thickness of extensible canopy body and quality are bigger, this has not only increased manufacturing cost, has also reduced draught area simultaneously.
The utility model content
The utility model purpose is to provide a kind of flexible back timber of hydraulic support of band side protecting mechanism of compact conformation.
For achieving the above object, the utility model can be taked following technical proposals:
The hydraulic support of the band side protecting mechanism described in the utility model back timber that stretches, it comprises front-axle beam, slip is inserted into the extensible canopy in the described front-axle beam box-shaped cavity, is articulated in the face guard of described extensible canopy front end, and is arranged on the flexible jack between front-axle beam and the extensible canopy; Be positioned at the place, centre position at the front-axle beam soffit and be provided with sunk area, be provided with the wall supporting jack in described sunk area, the piston rod and the face guard of described wall supporting jack are hinged.
The utility model advantage is to take described face guard is connected by described wall supporting jack with front-axle beam, has so just saved carriage, has reduced the thickness and the quality of extensible canopy body; The cylinder body of wall supporting jack is arranged on the sunk area that the front-axle beam soffit is positioned at the setting of place, centre position, and making whole girder construction compactness had increased the machine of mistake height, had also increased draught area simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in the figure, the hydraulic support of the band side protecting mechanism described in the utility model back timber that stretches, it comprises front-axle beam 1, slides to be inserted into extensible canopy 2 in the described front-axle beam 1 box-shaped cavity, be articulated in the face guard 3 of described extensible canopy 2 front ends, and be arranged on the flexible jack 4 between front-axle beam 1 and the extensible canopy 2; Be positioned at the place, centre position at front-axle beam 1 soffit and be provided with sunk area 5, be provided with wall supporting jack 6 in described sunk area 5, the piston rod of described wall supporting jack 6 and face guard 3 are hinged.
