Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The coal mine end support supporting device comprises a side guard plate 1, a jack 2, an upper supporting rod 3, a lower supporting rod 4, a composite hinged wheel 5, a locking device 6 and a side extension plate 8 on the side surface of a main top beam 7 of an end support, wherein the side extension plate 8 is vertically arranged; the outer side contour surface of the side extension plate 8 is sequentially provided with an upper lug seat 81, a middle lug seat 82 and a lower lug seat 83 from top to bottom; the upper ear seat 81 is hinged with the inner end of the side guard plate 1, and the outer end of the side guard plate 1 is hinged with the upper end of the upper support rod 3; the middle lug seat 82 is hinged with the upper end of the jack 2; the lower ear seat 83 is hinged with the lower end of the lower support rod 4; the lower end of the upper supporting rod 3, the upper end of the lower supporting rod 4 and the lower end of the jack 2 are hinged to the composite hinged wheel 5, the jack 2, the upper supporting rod 3 and the lower supporting rod 4 are located in the same vertical plane, and the plane is perpendicular to the side guard plate 1.
The jack 2 is used as a first supporting structure to control the lifting of the side guard plate. When the side guard plate 1 rotates to the upper contour surface and the main top beam 7 are level, the lower end of the upper supporting rod 3 and the upper end of the lower supporting rod 4 are locked and fixed through the locking device 6 and serve as a second supporting structure, when the jack 2 cannot work under unexpected conditions, the second supporting structure can still achieve a supporting effect, and the safety of end supporting is greatly improved.
A first plate-shaped structure 31 extends downwards from the lower end of the upper support rod 3, and a plurality of first fixing holes 32 are formed in the first plate-shaped structure 31; a second plate-shaped structure 41 extends upwards from the upper end of the lower support rod 4, and a plurality of second fixing holes 42 are formed in the second plate-shaped structure 41; when the upper contour surface of the side guard plate 1 and the upper contour surface of the main top beam 7 are flush, the first fixing holes 32 and the second fixing holes 42 are correspondingly overlapped; the locking device 6 comprises a bolt 61 and a nut 62, and the bolt 61 passes through the first fixing hole 32 and the second fixing hole 42 and is matched with the nut 62 to fixedly lock the upper support rod 3 and the lower support rod 4.
When the upper contour surface of the side guard plate 1 and the upper contour surface of the main top beam 7 are level, the outer side included angle formed by the upper supporting rod 3 and the lower supporting rod 4 is less than 180 degrees, and the upper supporting rod 3 and the lower supporting rod 4 are concave at the position of the composite hinged wheel 5. In the process that the jack 2 extends to press the composite hinged wheel 5 and enable the side guard plate 1 to rotate upwards, the height of the side guard plate 1 is the highest only when the upper support rod 3 and the lower support rod 4 are located on the same straight line. If go up branch 3 with the outside contained angle that lower branch 4 formed is less than 180 degrees, then inefficacy as first bearing structure, second bearing structure's intensity is also not enough to when causing side guard plate 1 to rotate downwards, it is inevitable that oppression jack 2 contracts rather than outwards pulling jack 2, it may cause 2 internal structure of jack loose drops to pull jack 2, and then makes bearing structure wholly collapse, and jack 2 is oppressed the shrink and then can not cause bearing structure's collapse, but has a minimum shrink degree, therefore still can remain some supporting role, improve the utility model discloses a security.
The jack 2 is a hydraulic jack, the jack 2 is connected with a hydraulic control valve through a liquid supply pipeline, and the hydraulic jack is high in strength and easy to control.
Four groups of jacks 2 are correspondingly arranged on a single side guard plate 1 and determined according to the actual conditions of a construction site. Meanwhile, the distance between the bracket and the coal pillar is designed and processed, the length of the side protection plate 1 is 1.5m, the side protection plate 1 is formed by processing an iron plate with the thickness of 30mm, when the distance between the end bracket and the coal pillar coal wall is more than 0.5m, the side protection plate 1 with the width of 0.6m is used for supporting, and when the distance between the end bracket and the coal pillar coal wall is more than 1m, the side protection plate 1 with the width of 1m is used for supporting. Weld on ground at the machine maintenance factory earlier stage and carry out the contrast test, transport the installation in the pit after side guard plate 1 has processed, with side guard plate 1, jack 2, go up the pole 3, down the pole 4 and the side extension board 8 articulates well separately to for jack 2 connects the liquid supply pipeline.
And a plurality of reinforcing ribs 9 are arranged on the lower contour surface of the side guard plate 1, so that the strength of the side guard plate 1 is improved.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
