Description
Technical field
The present invention relates to it is a kind of can before frame lapping joint support top side protecting mechanism, belong to technical field of coal mine equipment.
Background technology
With east China superficial part coal resources exploitation totally, the exploitations of coal resources is gradually shifted to deep, in
The working face dynamic disaster problem that this brings simultaneously is also outstanding day by day, especially under the conditions of the high working face of deep, the coal of working face
Wall flaps side phenomenon frequently occurs, and becomes the technical barrier of working face safe working.
At present, three-stage side protecting mechanism of hydraulic support is the main means for protecting coal wall.Three-stage side protecting mechanism adapts to high working face
Working face mining condition adds in third level protection coal wall safety again under conditions of former two-stage face guard.For example, as it is known that one kind
Three-stage side protecting mechanism of hydraulic support, the level-one face guard being hinged including the extensible canopy front end with hydraulic support top beam and setting
Level-one wall supporting jack on the extensible canopy；The mandril of the level-one wall supporting jack passes through small with level-one wall supporting postlaminar part
Four-bar mechanism is hinged；Secondary protecting side plate is hinged in the front end of level-one face guard, is hinged in the front end of the secondary protecting side plate
There is three-stage side protecting plate；Secondary protecting side jack, the mandril and two of the secondary protecting side jack are provided on level-one face guard
Grade wall supporting postlaminar part is hinged；Three-stage side protecting jack, the top of the three-stage side protecting jack are provided on secondary protecting side plate
Bar is hinged with three-stage side protecting postlaminar part by small four-bar mechanism.
Although above-mentioned three-stage side protecting plate can realize the supporting requirement to working face wall, it can not be to hydraulic support top beam
Front top plate carries out supporting, and once three-stage side protecting plate is withdrawn, the wall caving coal body of bulk drops and staff and mining will be set
It is standby to damage.Therefore, exposed top plate and processing the wall caving coal body that drops become a great problem of urgent need to resolve in front of protective cradle.
The content of the invention
In order to overcome the above-mentioned deficiency of the prior art, the present invention provide it is a kind of can before frame lapping joint support top wall supporting machine
Structure, the side protecting mechanism can fully supporting roof with processing wall caving bulk coal body.
The present invention solve its technical problem the technical solution adopted is that：Including hydraulic support, mounted on the top of hydraulic support
The three-stage side protecting mechanism and support top of beam front end visit beam, and support top is visited beam and is arranged in front of the top beam of hydraulic support, with level-one wall supporting
Plate is hinged, and further includes the support top string bag and fixed network anchor pole, and the support top string bag includes jacking stent and the shaft type string bag, and the support top string bag is fixed on
On level-one face guard, after the stretching, extension of level-one face guard, jacking stent just visits beam with support top and docks the top plate branch to form top beam front end
Shield, the shaft type string bag include carbon fibre web, and carbon fibre web is fixed on by fixed network anchor pole on coal wall.
Compared with prior art, it is of the invention it is a kind of can before frame lapping joint support top side protecting mechanism, pass through the support top string bag
Jacking stent joint support top, which visits beam, further to carry out supporting to top plate, can realize the supporting to exposed top plate before stent,
Wall caving problem caused by effectively preventing top plate roof fall, and pass through fixed network anchor pole and reinforcement supporting is carried out to coal wall, reinforce coal wall；And
In the case that there is wall caving in coal wall, can realize to wall caving coal wall fall buffering, specifically using fixed network anchor pole bottom bar with
Carbon fibre web compound action, into row buffering and collection, prevents bulk wall caving coal body to personnel and sets to the whereabouts of coal wall caving coal body
It is standby to damage.Whole device is esy to use, safe and reliable, adaptable, reduces the cost of wall caving prevention.
