Description
Technical field
The present invention relates to the material compaction apparatus, be specially a kind of device for compacting filled materials in coal mining goaf.
Background technology
The compacting filled materials in coal mining goaf technology is the effective way of present solution " three press down coal " safe working.In the coal mining process because complete filling has been carried out in the goaf; Guaranteed that depression does not take place on the production zone face of land; Also realize no coal pillar mining simultaneously and created condition for production zone; So not only protect face of land natural ecological environment to greatest extent, but also can liberate " three times " dull resource significantly, realize that the exploitation to greatest extent of non-renewable coal resources is reclaimed.Coal-face remains the open-off cut state with adopting with filling out, changed fully traditional inbreak formula production practice with and roof movement and ore deposit press and manifest rule.This mining type of filling control top board is carried out in the goaf do not rupture and do not stride, except that favourable, also play an important role simultaneously at aspects such as preventing common mine disaster, realization safety in production to water-retaining production; After goaf filling; Avoid leaking out of goaf, distinguished and admirablely remained constantly, improved drafting efficiency greatly; Thoroughly stoped generation of the gushing out of goaf gas, spontaneous combustion of coal seam, old empty water leak accident etc., can be described as and achieve many things at one stroke.Reach above-mentioned effect, most critical just is compaction process and equipment.After coal-face is pushed ahead the formation goaf; Attal is transported to the work plane rear portion carries out filling; Then need attal is carried out the effect that compacting could realize that coal mining goaf filling technology is produced, yet be not used in the device that filled materials in coal mining goaf is carried out compacting at present.
Summary of the invention
The present invention provides a kind of device for compacting filled materials in coal mining goaf in order to solve the problem of filled materials in coal mining goaf not being carried out the device of compacting now.
The present invention adopts following technical scheme to realize: device for compacting filled materials in coal mining goaf; Comprise base, be fixed on support and some oil cylinders on the base; One end of oil cylinder is fixed on support front side (a horizontal side); The other end of oil cylinder all is fixed with placed adjacent and leading flank compacting block at grade, is connected with hydraulic control on the oil cylinder.Hydraulic control is to be known configurations.After attal is transported to the coal mining goaf; Start the oil cylinder that hydraulic control at first drives bottom and move back and forth, and then drive corresponding compacting block and move reciprocatingly, attal is carried out compacting; After reaching the consolidation effect of regulation; Hydraulic control automatically switches to last layer and accomplishes same action, bottom-up up to top one deck oil cylinder accomplish and move back and forth, realize the whole attal in coal mining goaf is carried out the requirement of compacting.
Compacting block is a hollow-core construction, and the cylinder barrel bottom of oil cylinder is fixed on the support front side, and the piston rod of oil cylinder is placed in the compacting block and with piston rod one end and compacting block and fixes.Compacting block adopts hollow-core construction; Weight is lighter, can move reciprocatingly by driving oil cylinder promotion compacting block with less hydraulic coupling, satisfies the requirement of compacting filling material; And oil cylinder places the dust that has prevented attal in the compacting block to drop on the oil cylinder, influences the normal use of oil cylinder.
The rear end and the support that all are with carriage and carriage on the fore-and-aft direction of compacting block are fixed, and set up guide pad between carriage and the compacting block sidewall.When filled materials in coal mining goaf is filled, reduce the gap between carriage and the compacting block through setting up guide pad, prevent that dust from getting into; The effect of simultaneously seesawing of compacting block being played guiding and being reduced friction reduces the vertically stressed of compacting block, thereby improves the life-span of device for compacting filled materials in coal mining goaf.
The hydraulic support that the support rear side is fixed with and base is fixing, when the compacting block reciprocating motion was carried out compacting to attal, hydraulic support provided guarantee to the stability of whole device for compacting filled materials in coal mining goaf.
Support is made up of guide pin bushing and the guide pillar that is placed in the guide pin bushing; Oil cylinder is fixed on the guide pin bushing of support; Between the compacting block of bottom or carriage and base, set up elevator chamber, elevator chamber comprise down case lid be enclosed within that nowel covers and with the fixing upper box lid of guide pin bushing, be provided with hydraulic jack in the elevator chamber; The effect of elevator chamber is in order to satisfy the requirement that system for compacting adapts to the different mining high altitude; When the whole height of compacting block is lower than the height in coal mining goaf, can cause the problem that top, goaf can't the compacting fill material, a hydraulic jack that at this moment only needs to drive in the elevator chamber done stretching motion, thereby at the upper box lid that guarantees elevator chamber during with the unseparated state of following case lid; Upper box lid moves upward; And then guide pin bushing and compacting block held up simultaneously, the attal on top also is compacted, thereby has guaranteed the compacting that is full of of the full mining height of filled materials in coal mining goaf.
The present invention has filled up the blank of filled materials in coal mining goaf not being carried out the device of compacting at present; For the realization of compacting filled materials in coal mining goaf technology provides condition, have simultaneously simple in structure, be convenient to operation, reliable, consolidation effect significantly and low cost and other advantages.
