Abstract
The invention discloses a kind of rear back timber multi-pace filling hydraulic support of filling for goaf, belong to underground coal mine fully-mechanized coalface support apparatus technical field.The rear top beam rear end of this support has vented enclosure, and extensible canopy is inserted in this vented enclosure, and the rear base of this support is connected with extensible member.When the coal mining part of this support moves forward, 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 regulate, thus, the multi-pace realizing this support moves frame, and then ensures the setting time that rear portion is filled.
Description
Technical field
The present invention relates to underground coal mine fully-mechanized coalface support apparatus technical field, particularly a kind of rear back timber multi-pace filling hydraulic support of filling for goaf.
Background technology
In prior art, there is following shortcoming or deficiency in the four post paste filling hydraulic brackets of filling for goaf: 1) moves frame owing to can not realize multi-pace, cannot ensure the setting time of rear portion filling; 2) support stability is not high; 3) backfilled enclosed space is not formed.
Summary of the invention
In order to solve the problem, the present invention proposes and a kind ofly can realize the rear back timber multi-pace that multi-pace moves frame, stability high and fill hydraulic support.
The rear top beam rear end that rear back timber multi-pace provided by the invention fills hydraulic support has vented enclosure, extensible canopy is inserted in described vented enclosure, rear base is connected with extensible member, when the coal mining part of described support moves forward, when the free end of described extensible canopy and the free end of extensible member maintain static, the distance of stretch out and draw back of described extensible canopy and extensible member can regulate.
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 post-tensioning jack.
As preferably, described support component is support jack.
As preferably, described rear bracket is connected with baffle plate assembly, one end of baffle plate jack is connected to rear bracket, and the other end is connected to described baffle plate assembly, and under the effect of described baffle plate jack, described baffle plate assembly can angularly swing.
As preferably, described baffle plate assembly is made up of removably plank frame.
Rear back timber multi-pace filling hydraulic support provided by the invention is worked as coal mining part and is moved forward, 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 regulate, thus, the multi-pace realizing this support moves frame, and then ensures the setting time that rear portion is filled.
Accompanying drawing explanation
Fig. 1 for rear back timber multi-pace that the embodiment of the present invention provides fill hydraulic support after back timber and extensible canopy be in the schematic diagram of contraction state;
Fig. 2 for rear back timber multi-pace that the embodiment of the present invention provides fill hydraulic support after back timber and extensible canopy be in the schematic diagram of extended state.
Detailed description of the invention
In order to understand the present invention in depth, below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
See accompanying drawing 1 and accompanying drawing 2, rear back timber 1 rear end that rear back timber multi-pace provided by the invention fills hydraulic support has vented enclosure, extensible canopy 2 is inserted in vented enclosure, rear base 3 is connected with extensible member (in the present embodiment, as a kind of concrete implementation of extensible member, extensible member is post-tensioning jack 4), when the coal mining part of this support moves forward, when the free end of extensible canopy 2 and the free end of post-tensioning jack 4 maintain static, the distance of stretch out and draw back of extensible canopy 2 and post-tensioning jack 4 can regulate.
Based on preceding solution, rear back timber multi-pace hydraulic support provided by the invention is made up 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, support component is provided with 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.Thus, make the support effect of brace summer 5 and extensible canopy 2 pairs of top boards better.
Wherein, rear bracket 6 is connected with baffle plate assembly 7, one end of baffle plate jack 8 is connected to rear bracket 6, and the other end is connected to baffle plate assembly 7, and under the effect of baffle plate jack 8, baffle plate assembly 7 can angularly swing.Thus 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 up of removably plank frame, and this plank frame can be the shape such as wedge shape, slot shape.Thus the height of baffle plate assembly 7 can change with the height change of this support.
Rear back timber multi-pace filling hydraulic support provided by the invention moves forward when the coal mining part of hydraulic support, when the free end of extensible canopy 2 and the free end of post-tensioning jack 4 maintain static, the distance of stretch out and draw back of extensible canopy 2 and post-tensioning jack 4 can regulate, thus, the multi-pace realizing this support moves frame, and then ensures the setting time that rear portion is filled.
Above-described detailed description of the invention; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only the specific embodiment of the present invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
