Abstract
The utility model discloses a rotary two-level side wall support mechanism. The utility model comprises a first level side wall plate, which is articulated with a front end of a hydraulic support roof beam and a second level side wall plate, which is articulated with a front end of the first level side wall plate; a back end of the first level side wall plate is connected with a connecting joint of a first level side wall jack on the roof beam through an articulated piece; a second level side wall jack is mounted on the first level side wall plate; and a mandril of a second level jack is articulated with a back end of the second level side wall plate. With the structure of the utility model, the side wall jack can stretch out in time after the coal mining of a coal mining machine, the first level side wall plate supports a roof plate timely to prevent roof caving, the second level side wall plate supports a coal wall timely to avoid side fall, and the side wall plate can be rapidly taken back at pulling. The first level side wall plate and the second level side wall plate simultaneously support the coal wall after moving a bracket, side wall height can reach 2.8 meter upwards, the two-level side wall can rotate 180 degree relative to the roof beam, and the efficiency and safety of large and high coal mining work face are improved.
Description
Technical field
The utility model relates to the mine hydraulic support, relates in particular to the rotary two-stage side protecting mechanism that is used for hydraulic support.
Background technology
Hydraulic support is mainly used in the down-hole coal excavation work plane, and when coal-winning machine was worked, the hydraulic support back timber played the effect of supporting coal face roof.But after coal-winning machine has been adopted coal, coal wall caving, roof collapse phenomenon usually take place, directly influenced the safety and the efficient of coal-face.Especially large-mining-height working surface needs the height of wall supporting big, needs immediate support top board and rib.
The utility model content
The utility model purpose is to provide a kind of rotary two-stage side protecting mechanism that is used for hydraulic support that can prevent effectively that coal wall caving, roof collapse phenomenon from taking place.
For achieving the above object, the utility model can be taked following technical proposals:
Rotary two-stage side protecting mechanism described in the utility model comprises and is arranged on the one-level face guard that hydraulic support back timber front end is hinged, and is hinged with the secondary face guard at the front end of described one-level face guard; The rear end of one-level face guard is connected with the connector of one-level wall supporting jack on being arranged on described back timber by articulated elements; The one-level face guard is provided with secondary wall supporting jack, and the push rod of described secondary jack and secondary face guard rear end are hinged.
Described articulated elements is quarter butt, stock; Push rod front end at described one-level wall supporting jack is hinged with a connector, and the other end of described connector and described quarter butt, stock are hinged; The other end of described stock and the front end of back timber are hinged, and the other end of quarter butt and one-level face guard rear end are hinged.
The utility model is owing to take set cap to be provided with rotatable radial type secondary side protecting mechanism, therefore after having adopted coal, can in time the wall supporting jack be stretched out by coal-winning machine, one-level face guard immediate support top board prevents roof fall, secondary face guard immediate support lives rib in case wall caving, and can regain face guard rapidly when trying to stop people from fighting each other.Having moved behind the support one-level face guard and the supporting simultaneously of secondary face guard and lived rib, make the wall supporting height can reach more than 2.8 meters, is wall supporting height maximum in the present hydraulic support.Therefore the two-stage wall supporting has adapted to the worker's environment under the mine, the efficient and the safety that have improved big mining height coal-face better with respect to rotatable 180 degree of back timber.
