Abstract
The utility model provides a swing board plug skylight-type hydraulic supporter for laying a top coal, composed of a front beam, a telescopic beam, a top beam, a base, a shielding device with a coal laying window. The hydraulic supporter is characterized in that the coal laying window is provided wit a pivot shaft and a rocking plate rotated around the pivot shaft, and the rocking plate is provided with a sliding insert plate. The hydraulic supporter has good top coal laying effect and supporting stability, being suitable for being used for exploiting a coal seam with a thickness of 5-12 meters.
Description
The utility model relates to a kind of improved caving roof coal hydraulic support, particularly exploits the hydraulic support of swinging plate that has of high seam.
Existing caving roof coal hydraulic support mainly is made up of extensible canopy, front-axle beam, back timber, shielding apparatus and base etc., has the twitch formula and put the coal window on shielding apparatus.In exploitation high seam caving coal process, the twitch flashboard of putting the coal window is opened, and the top coal is from putting the coal window.When ature of coal was more open, the top coal fell from putting the coal window easily.But when ature of coal was firm, the top coal of bulk will block putting the coal window, stopped that the continuation of top coal is fallen.General caving roof coal hydraulic support can not be got rid of in time because the fault that the bulk top coal that blocks causes has so just been brought influence to production, and the workman is when the coal of eliminating puts that the coal window blocks top, and is difficult and dangerous.
Task of the present utility model provides a kind of improved caving roof coal hydraulic support, and it can be applied in the high seam top coal caving of Coal Production, and can solve effectively in the top coal slump process, stops up the problem of putting the coal window.
The utility model is finished like this: the shielding apparatus of caving roof coal hydraulic support put coal window place, the rocker that pivotally rotates is equipped with the plate of slip on rocker.When at let-down top coal, the rocker of putting on the coal window rotates a suitable angle, and plate upwards slides along rocker simultaneously, puts the coal window and opens, and the top coal is put the coal window from what open.Put the coal window if block top coal is stuck in, stopped that the continuation of top coal is fallen, rocker is by swinging loosening or extruding lump coal, and plate is inserted the broken lump coal that blocks simultaneously; The a large amount of top coal if fall has little time transportation, and putting the coal window can suitably turn down, and reduces the whereabouts amount.The utility model result of use is good, can reach the purpose of in time reliable let-down top coal.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 be Fig. 1 along A to view.
Fig. 3 is the partial sectional view of putting the coal window on the shielding apparatus.
With reference to accompanying drawing 1～3, extensible canopy 1 can move along front-axle beam 2, and front-axle beam jack 3 promotes front-axle beam 2 swings.Back timber 4 is supported and is connected on the base 13 by front standing pillar 9 and back prop 10.Shielding apparatus 6 connects with base 13 by front rod 7 and back link 8.The working depth of hydraulic support is adjusted by the lifting of front standing pillar 9 and back prop 10, and it heightens 1.6～2.8 meters of scopes.Push rod 11 is ground-engaging elements of hydraulic support, moves rear portion slide jack 12 and is used to pass the rear portion conveyer belt.Put coal rocker jack 5 one ends and be connected on the back timber 4, an end connects with the rocker 15 of putting coal window 19 places, is used for promoting the rotation of rocker 15 around pivot 14.The rotational angle of rocker 15, when hydraulic support is in high workload position, on put 50 °, 42 ° in the bottom; When hydraulic support is in minimum operating position, on put 21 °, 60 ° in the bottom.The plate 16 that the lower end band is split angle 18 is slided up and down along rocker 15 by 17 controls of plate oil cylinder, the stretching degree that the rotation by rocker 15 and the slidable adjustment of plate 16 are put coal window 19.
The hydraulic support that the utility model provides has good caving coal effect and stability of strutting system, and supporting intensity is 0.83～0.88 MPa, is applicable to the exploitation of 5～12 meters high seams.
Claims (3)
1, caving roof coal hydraulic support, by extensible canopy 1, front-axle beam 2, back timber 4, base 13 with have the shielding apparatus 6 of putting coal window 19 and form, it is characterized in that having can be along the plate 16 of its slip at the rocker 15 of putting pivotally 14 on the coal window 19 and rotating around pivot 14 on rocker 15.
2, hydraulic support according to claim 1 is characterized in that the caving coal jack 5 that has control rocker 15 to rotate around pivot 14.
3, hydraulic support according to claim 1 is characterized in that having the plate oil cylinder 17 of control plate 16 along rocker 15 slips, and angle 18 is split in the lower end of plate 16.
