Abstract
The utility model discloses a back top beam multi step pitch filling hydraulic support for filling goafs, and belongs to the technical field of underground coal mine integrated mechanical coal mining face timbering equipment. An open type box body is arranged on the back end of a back top beam of the support, a flexible beam is inserted in the open type box body, and a back base of the support is connected with a flexible part. A coal mining part of the support moves forward, when the free end of the flexible beam and the free end of the flexible part are fixed, flexible distances of the flexible beam and the flexible part can be adjusted, and therefore multi step pitch support movement of the support can be achieved, and setting time of back filling can be guaranteed.
Description
Technical field
The utility model relates to fully-mechanized coalface support apparatus technical field under coal mine, and particularly a kind of rear back timber multi-pace for the goaf filling is filled hydraulic support.
Background technology
In prior art, the four post paste filling hydraulic brackets that are used for filling in the goaf exist following shortcoming or deficiency: 1) owing to can not realizing that multi-pace moves frame, can't guarantee the setting time of rear portion filling; 2) support stability is not high; 3) do not form backfilled enclosed space.
The utility model content
In order to address the above problem, to the utility model proposes and a kind ofly can realize that multi-pace moves frame, the high rear back timber multi-pace of stability is filled hydraulic support.
The rear top beam rear end that the rear back timber multi-pace that the utility model provides is filled hydraulic support has the open type casing, extensible canopy is inserted in described open type casing, be connected with extensible member on rear base, when the coal mining of described support partly moves forward, when the free end of described extensible canopy and the free end of extensible member maintained static, the distance of stretch out and draw back of described extensible canopy and extensible member can be regulated.
As preferably, the free end of described extensible canopy is connected with brace summer, and the free end of described extensible member is connected with rear bracket, is provided with support component between described brace summer and rear bracket.
As preferably, described extensible member is the post-tensioning jack.
As preferably, described support component is support jack.
As preferably, be connected with baffle plate assembly on described rear bracket, an end of baffle plate jack is connected in rear bracket, and the other end is connected in described baffle plate assembly, and under the effect of described baffle plate jack, described baffle plate assembly can be angle swinging.
As preferably, described baffle plate assembly is made of removably plank frame.
The rear back timber multi-pace that the utility model provides is filled hydraulic support and is partly moved forward when mining, when the free end of extensible canopy and the free end of extensible member maintain static, the distance of stretch out and draw back of extensible canopy and extensible member can be regulated, thereby, the multi-pace of realizing this support moves frame, and then guarantees the setting time that fill at the rear portion.
Description of drawings
The rear back timber multi-pace that Fig. 1 provides for the utility model embodiment is filled the schematic diagram that back timber and extensible canopy after hydraulic support are in contraction state;
The rear back timber multi-pace that Fig. 2 provides for the utility model embodiment is filled the schematic diagram that back timber and extensible canopy after hydraulic support are in extended state.
The specific embodiment
In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is elaborated.
Referring to accompanying drawing 1 and accompanying drawing 2, rear back timber 1 rear end that the rear back timber multi-pace that the utility model provides is filled hydraulic support has the open type casing, extensible canopy 2 is inserted in the open type casing, be connected with extensible member (in the present embodiment on rear base 3, a kind of concrete implementation as extensible member, extensible member is post-tensioning jack 4), when the coal mining of this support partly moves forward, when the free end of the free end of extensible canopy 2 and post-tensioning jack 4 maintained static, the distance of stretch out and draw back of extensible canopy 2 and post-tensioning jack 4 can be regulated.
Based on the aforementioned techniques scheme, the rear back timber multi-pace hydraulic support that the utility model provides is comprised of front back timber, balance jack, upper connecting rod, rear back timber 1, column, base (comprising front base and rear base 3), back link, front rod, passing frame and advancing jack, post-tensioning jack 4, rear bracket 6, baffle plate jack 8, baffle plate assembly 7, support jack 9, brace summer 5, extensible canopy 2 etc.; Wherein, front back timber, balance jack, upper connecting rod, rear back timber, column, base, back link, front rod, passing frame and advancing jack etc. cooperatively interact and form general hydraulic support.
Wherein, the free end of extensible canopy 2 is connected with brace summer 5, and the free end of post-tensioning jack 4 is connected with rear bracket 6, be provided with support component between brace summer 5 and rear bracket 6, in the present embodiment, as a kind of concrete implementation of support component, support component is support jack 9.Thereby, make the support effect of brace summer 5 and 2 pairs of top boards of extensible canopy better.
Wherein, be connected with baffle plate assembly 7 on rear bracket 6, an end of baffle plate jack 8 is connected in rear bracket 6, and the other end is connected in baffle plate assembly 7, and under the effect of baffle plate jack 8, baffle plate assembly 7 can be angle swinging.Thereby baffle plate assembly 7 can be rocked to specific inclination angle according to filling needs, realizes better filling.
Wherein, baffle plate assembly 7 is made of removably plank frame, and this plank frame can be the shapes such as wedge shape, slot shape.Thereby the height of baffle plate assembly 7 can change with the height change of this support.
The rear back timber multi-pace that the utility model provides is filled hydraulic support and is partly moved forward when the coal mining of hydraulic support, when the free end of the free end of extensible canopy 2 and post-tensioning jack 4 maintains static, the distance of stretch out and draw back of extensible canopy 2 and post-tensioning jack 4 can be regulated, thereby, the multi-pace of realizing this support moves frame, and then guarantees the setting time that fill at the rear portion.
The above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only the specific embodiment of the present utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
