Description
Technical field
The utility model relates to Coal Production equipment, is specifically related to a kind of colliery and combines and to free termination, tunnel sublevel caving hydrau lic support in the product.
Background technology
Along with the coal mine machinery coal mining, particularly combine the development of putting, country has proposed requirements at the higher level to resource utilization.In the colliery fully mechanized coal face was produced, to the coal on top, fully mechanized coal face tunnel (have also comprise transition frame), because the restriction of existing equipment abandons old man (goaf) usually, it accounted for the 4-6% that can adopt resource, causes the very big wasting of resources.Therefore,, improve resource utilization, reclaim more precious resources if the coal let-down at top, back on the face end support of tunnel is reclaimed,
Summary of the invention
The purpose of this utility model is at the prior art above shortcomings, proposes termination, fully mechanized coal face tunnel, a kind of colliery sublevel caving hydrau lic support, makes it adapt to tunnel end support condition and the requirement of caving coal, improves the utilization rate of coal resources.
Face end support is set in fully mechanized coal face tunnel, colliery mainly solves the tunnel and move supporting, place in the face end support elevating conveyor switch through fully mechanized coal face before and after conveyer come coal.And the termination sublevel caving hydrau lic support that the utility model proposes, should solve the termination, tunnel and move supporting, solve the let-down of top, termination, tunnel coal again, elevating conveyor on the face end support, two conveyers come coal before and after should switching through work plane, push up the coal of putting after connecing the fortune face end support again, the pattern of face end support and structure should adapt to the tunnel and move the supporting condition variation, again the smooth let-down of the top coal of different condition on the face end support of tunnel is reclaimed, therefore for adapting to roadway support condition and the requirement of caving coal, the utility model by the following technical solutions:
Termination, fully mechanized coal face tunnel, a kind of colliery sublevel caving hydrau lic support is combined by the side arm that is major-minor shelf structure form, middle frame and after-frame.Middle frame and after-frame are hinged with bearing pin, and side arm is connected by passing jack with middle frame (2), can realize moving certainly and replacing reach.Set between the major-minor frame and transfer jack and raise the jack spacing; During elevating conveyor is placed between the body frame base of frame and after-frame or on the base; When conveyer is placed between the body frame base, transfer jack between the body frame base, being provided with, but spacing when elevating conveyor is placed on the body frame base, is not established then.
Described after-frame is made up of base, column, back timber, caving shield, front rod, back link, tail boom, tail boom jack, plate and plate jack, described back timber is hinged on the base by upright supports, caving shield is connected top beam rear end, and by front rod, back link support, tail boom is hinged on the rear end of caving shield, supported by the tail boom jack, plate is installed in the tail boom by plate jack telescopically.Described tail boom, tail boom jack, plate and plate jack constitute puts coal retaining cash mechanism.
In sum, the utility model can satisfy the comprehensive tunnel of being rivals in a contest, colliery and move the new demand that supporting and caving coal are moved in the termination, can mostly be country and reclaim coal resources 4-6%, combines the development of putting and improve resource utilization significant to the colliery.

The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is elaborated.
Shown in Fig. 1 and Figure 1A, the termination sublevel caving hydrau lic support is combined by side arm 1, middle frame 2 and after-frame 3, each frame all adopts major-minor shelf structure form, body frame 22 is placed in the middle, elevating conveyor 21 connects the fortune coal after placing therebetween (or on it) and stretching to after-frame, subframe 23 splits body frame 22 both sides, and the back timber on body frame 22 tops, caving shield are overall structure, and the base of bottom is a separate form.Middle frame 2 and after-frame 3 usefulness bearing pins 8 are hinged, and side arm 1 is passed jack 4 with middle frame 2 usefulness and is connected, and realizes passing.Transfer jack 7 between the body frame base, being provided with, spacing (conveyer is placed on the body frame base and then do not established).Between the major-minor frame, set and transfer jack 5 and raise jack 6 spacings.Side arm 1 has oneself and moves support performance and advance support function, and is provided with extensible canopy 20 at front end, the space after moving by extensible canopy 20 servo-actuateds shielding side arm 1 and middle frame 2.Have caving coal and retaining cash function at after-frame 3, be provided with and put coal retaining cash mechanism,,, the side guard board by jack control is set according to tunnel width and needs in subframe back timber (comprising after-frame caving shield, tail boom) two outsides of after-frame.Constitute the complete framework of termination, tunnel caving coal sectional shelf-unit thus, bear the function that supporting and caving coal are moved in the termination, tunnel.
Referring to Fig. 2, Fig. 2 A and Fig. 2 B, the major-minor shelf structure of after-frame 3 of the present utility model is identical, forms by base 9, column 10, back timber 11, caving shield 12, front rod 13, back link 14, tail boom 15, tail boom jack 16, plate 17 and plate jack 18.Wherein back timber 11 is supported on the base 9 by column 10 connections, caving shield 12 is hinged on back timber 11 rear ends, and by front rod 13 and back link 14 supports, tail boom 15 is hinged on the rear end of caving shield 12, be installed in the tail boom 15 by plate jack 18 telescopicallies by 17, by plate jack 18 control plates 17 collapsing lengths, guarantee that the best puts coal and effective retaining cash.
Referring to Fig. 3 and Fig. 3 A, tail boom 15, tail boom jack 16, plate 17 and plate jack 18 constitute the described coal retaining cash mechanism of putting.The back timber 11 and the caving shield 12 on the body frame top of described after-frame 3 are overall structure, and tail boom 15 that the back is hinged and plate 17 are divided into totally three of both sides and centres.In two arranged outside of the back timber 11 of the subframe of after-frame 3, caving shield 12, tail boom 15 side guard board 19 by jack control is arranged.
The function of face end support caving coal is mainly implemented to finish by after-frame 3, after-frame 3 caving coal operating modes are as follows: when the tail boom 15 (master) of tail boom 15 (pair), plate 17 (pair) and the body frame of the subframe of after-frame 3, plate 17 (master) when being in holding state, the plate 17 (in main) of being regained the tail boom 15 (in main) of body frames by plate jack 18 is put coal.Available in case of necessity tail boom jack 16 adjusting angles treat that the top coal drains, and see when coming cash, stretch out plate 17 (in main) retaining cash by plate jack 18.When coal discharge outlet Gong Ding occurs and when failing to lay down the top coal, the tail boom 15 (main limit) of the tail boom jack 16 control body frame both sides of available body frame and by plate jack 18 control plates 17 (main limit) destroys the stable of coal discharge outlet Gong Ding and makes it continue to put more coal.Take these measures, make the tunnel face end support possess caving coal function, look for another approach, can reclaim the precious resources of 4-6% more for country for improving resource utilization.
