Abstract
The utility model discloses an in-coal gangue drawing hydraulic support which comprises a reversely-arranged edge protecting plate, a small four-connecting-rod mechanism, an edge protecting jack, and a top beam. The reversely-arranged edge protecting plate is arranged on the top beam and is provided with the small four-connecting-rod mechanism. One end of the edge protecting jack is arranged on the top beam, and the other end of the edge protecting jack is hinged with the small four-connecting-rod mechanism. Under the action of the edge protecting jack, the small four-connecting-rod mechanism pushes the reversely-arranged edge protecting plate to rotate. When the edge protecting plate is located at a horizontal angle, the vertical distance between the edge protecting plate and an upper plate of the top beam is larger than 400mm, the edge protecting plate timely support an upper coal layer lower than the upper plate of the top beam so as to ensure that the upper coal beam can not collapse after a middle gangue is drawn, and the purpose of drawing the gangue in coal is achieved. The edge protecting plate is reversely arranged, and is simple in structure. The distance between the upper coal layer supported temporarily and the upper top plate of the top beam is large so that installation and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of technical field of support apparatus in coal mine, and specifically a kind of coal mine fully-mechanized mining working is used for the dirt band coal seam and carries out the hydraulic support that coal is taken out cash.
Background technology
In most of coal seam at home, contain a large amount of dirt bands, particularly some girdles.Compose in the colliery resource today that storage reduces day by day, solve a great problem that becomes of dirt band coal seam or even dirt band ultra-thin coal seam exploitation.
At present, following problem has appearred in the coal seam of the type in recovery process:
(1) dirt band coal seam lapping exploitation at twice, cost of winning is high;
(2) in the dirt band coal seam, the coal seam support lower than 600mm abandons, and causes the serious waste of colliery resource.
Summary of the invention
For above deficiency, the purpose of this utility model, be to provide and take out the cash hydraulic support in a kind of coal, the utility model promotes the face guard rotation under the active force of wall supporting jack by linkage, coal seam in support, detach rear upper coal seam with spoil in the middle of guaranteeing and can not be caving, realize taking out in coal the purpose of cash, have advantages of that simultaneously plane separation back timber upper plate distance simple in structure, temporary lining is large, be easy for installation and maintenance.
For achieving the above object, the technical solution of the utility model is:
Take out the cash hydraulic support in a kind of coal, comprise back timber, the front portion of back timber is hinged with the wall supporting jack, the hinged little quadric chain of the other end of wall supporting jack, and the described little quadric chain other end is connected with face guard, and described face guard is hingedly fixed on back timber.
Further, face guard is counter to be contained on back timber, and when namely the backplate jack shrank, face guard was to the back timber rotating middle part; When the wall supporting jack stretched out, face guard carried the coal seam to inner rotary to horizontal plane.
Further, when described face guard outwards rotated to horizontal plane, the upper surface of face guard was lower than the back timber upper surface.
Further, when described face guard outwards rotated to horizontal plane, the upper surface of face guard was lower than back timber upper surface 400mm at least.The beneficial effects of the utility model show:
The face guard of the anti-dress of the utility model is arranged on back timber, and face guard is provided with little quadric chain, and wall supporting jack one end is arranged on back timber, and the other end and little quadric chain are hinged; Little quadric chain promotes the face guard rotation of anti-dress under the active force of wall supporting jack, when face guard is positioned at the angle of level, the face guard plane is lower than the back timber upper plate, and with the vertical distance of back timber upper plate greater than 400mm, the face guard immediate support is lower than the upper coal seam of back timber upper plate, detach rear upper coal seam with spoil in the middle of guaranteeing and can not be caving, realize taking out in coal the purpose of cash.
Compared with prior art, face guard is counter fills and the plane separation back timber upper plate distance of simple in structure, temporary lining is large, be easy for installation and maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1 is that face guard, 2 is that little quadric chain, 3 is that wall supporting jack, 4 is that back timber, 5 is quadric chain.
The specific embodiment:
Be described further with reference to the accompanying drawings, as scheme now by reference to the accompanying drawings the utility model to be further described, Fig. 1 is a kind of enforcement of the present utility model.
As shown in Figure 1, take out the cash hydraulic support in a kind of coal, face guard 1, little quadric chain 2, wall supporting jack 3, back timber 4, the quadric chain 5 of anti-dress.
Described face guard 1 instead fills, and face guard 1 is provided with little quadric chain 2, and wall supporting jack 3 one ends are arranged on back timber 4, and the other end and little quadric chain 2 are hinged.
When the face guard 1 of anti-dress is positioned at the angle of level when coal seam (in temporary lining), with the vertical distance of back timber 4 upper plates greater than 400mm.
During use, promote face guard 1 rotation of anti-dress under the active force of wall supporting jack 3 due to little quadric chain 2 of the present utility model, when face guard 1 is positioned at the angle of level, with the vertical distance of back timber 4 upper plates greater than 400mm, not only solved upper coal seam separate zone production can't supporting a difficult problem, and have simple in structurely, be easy for installation and maintenance and lift the large characteristics of end distance.
Claims (3)
1. take out the cash hydraulic support in a coal, comprise back timber, the front portion of back timber is hinged with the wall supporting jack, the hinged little quadric chain of the other end of wall supporting jack, it is characterized in that, the described little quadric chain other end is connected with face guard, and described face guard is hingedly fixed on back timber; Face guard is counter to be contained on back timber, and when namely the backplate jack shrank, face guard was to the back timber rotating middle part; When the wall supporting jack stretched out, face guard carried the coal seam to inner rotary to horizontal plane.
2. take out the cash hydraulic support in coal according to claim 1, it is characterized in that: when described face guard outwards rotated to horizontal plane, the upper surface of face guard was lower than the back timber upper surface.
