Abstract
The utility model discloses a shielding type hydraulic support which relates to the technical field of integrated mining equipment, and is invented to prolong the service life of a telescopic girder of the shielding type hydraulic support. The shielding type hydraulic support comprises a front girder; the stretching telescopic girder is arranged on the front girder, and a face guard plate is pivoted on the front girder. The shielding type hydraulic support disclosed by the utility model is suitable for supporting and controlling a top plate and a coal wall of a work surface.
Description
Technical field
The utility model relates to a kind of hydraulic shield support, relates in particular to the face guard of hydraulic shield support.
Background technology
Hydraulic support is the important component part of fully-mechanized mining equipment.It can reliably and effectively support and control the top board of work plane, isolates the goaf, prevents that spoil from getting into stope and advancing conveyer.
The pattern of hydraulic support is a lot.Classify according to hydraulic support and the interactional principle of top board, hydraulic support can be divided into three major types: brace type, protected type, support shield type.
Hydraulic shield support comprises front-axle beam, slides to be inserted into the extensible canopy in the said front-axle beam box-shaped cavity, is articulated in the face guard of said extensible canopy front end, and is arranged on the flexible jack between front-axle beam and the extensible canopy.
Existing hydraulic shield support, because face guard is articulated on the extensible canopy, like this, rib will act on the extensible canopy the reaction force of face guard when work, causes the damage of extensible canopy or flexible jack easily, thereby influences the application life of extensible canopy.
The utility model content
The utility model technical problem to be solved provides and a kind ofly can improve the extensible canopy hydraulic shield support in application life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of hydraulic shield support comprises front-axle beam, and said front-axle beam is provided with telescopic extensible canopy, on said front-axle beam, is articulated with face guard.
Further, said face guard comprises: the first order face guard that directly articulates with said front-axle beam, and the second level face guard that is articulated with said first order face guard; Directly be provided with first order telescopic hydraulic cylinder at said front-axle beam and said first order face guard; Between said first order face guard and said second level face guard, be provided with second level telescopic hydraulic cylinder.
Further, said face guard also comprises the third level face guard that is articulated with said second level face guard; Between said second level face guard and said third level face guard, be provided with third level telescopic hydraulic cylinder.
The utility model hydraulic shield support, because face guard directly is articulated on the attic, when work, rib just can not act on the extensible canopy the reaction force of face guard, thus the application life of having improved extensible canopy.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model aims to provide and a kind ofly can improve the extensible canopy hydraulic shield support in application life.Below in conjunction with accompanying drawing the utility model embodiment is specified.Should be clear and definite, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to shown in Figure 1, the utility model hydraulic shield support comprises front-axle beam 1, on said front-axle beam 1, is fitted with telescopic extensible canopy 2, on said front-axle beam 1, is articulated with face guard 3, and face guard 3 is articulated in the position of the front bottom end of front-axle beam 1.
The utility model hydraulic shield support, because face guard directly is articulated on the attic, when work, rib just can not act on the extensible canopy the reaction force of face guard, thus the application life of having improved extensible canopy.
For the ease of the face guard rib of fitting preferably, said face guard is a hierarchy, and specifically, said face guard 3 comprises: the first order face guard 31 that directly articulates with said front-axle beam 1, and the second level face guard 32 that is articulated with said first order face guard; Directly be provided with first order telescopic hydraulic cylinder 4 at said front-axle beam and said first order face guard; Between said first order face guard and said second level face guard, be provided with second level telescopic hydraulic cylinder 5.
Said first order telescopic hydraulic cylinder can be controlled the angle of said first order face guard, and said second level telescopic hydraulic cylinder can make said second level face guard fit with rib preferably.
For further being convenient to the face guard rib of fitting preferably, said face guard also comprises the third level face guard 33 that is articulated with said second level face guard; Between said second level face guard and said third level face guard, be provided with third level telescopic hydraulic cylinder 6.The three-stage side protecting plated construction can realize fluid pressure linkage, thereby makes the face guard rib of better fitting, and can play the wall supporting effect preferably, can improve the application life of extensible canopy again.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion by said protection domain with claim.
