Abstract
Disclosed is a filling bag for roof collapse belonging to a suspension device for mine under-pit breast. The utility model comprises a solidification pump, a filling can, and a filling bag; wherein, the filling can is connected with the solidification pump, the filling pump is connected with the filling bag, the filling bag has three flame-proof layers wherein the skin layer is rubber, the middle layer is fabric cloth and the inner layer is also rubber, foam is filled in the inner layer. The utility model uses the solidification pump to fill the inner layer of the filling bag with galvanic shock packing fluid. The utility model suspends the different scales of the roof collapse and enables the upper of the hydraulic support in the roof collapse to form an integral body. With the utility model, the utility model not only saves the suspension cost but also gradually reduces the height of the surpassing parts in the roof collapse. Connecting of The hydraulic support and the roof prevents the collapsing of the support and guarantees the safely and smoothly passing through the roof collapse.
Description
Technical field
The utility model relates to the suspension device that down-hole, a kind of mine fully-mechanized mining working uses, and very useful filling bag is emitted in specifically a kind of processing.
Background technology
In the fully-mechanized mining working manufacturing process of down-hole, mine, owing to be subjected to the influence of factors such as tomography, roof cracking band and mine pressure, roof fall accident in various degree often takes place in work plane, has a strong impact on the back production progress, so that cause casualties.When bigger roof fall takes place in the down-hole fully-mechanized mining working, traditional suspension device is a connection wire lath in top on the hydraulic support, use hydraulic support to provoke 3.0 * 0.16 * 0.18 meter timber, or below wire lath, use the hydraulic pressure monomer column hydraulic support beam point that re-packs, prevent the spoil inbreak.3.0 * 0.16 * 0.18 meter timber that these two kinds of methods are not only used is many, and used Master Cost is than higher, and timber and hydraulic pressure monomer column are all heavier, and the very difficulty that operates causes casualty accident easily; And can not make the supporting of pushing up on the hydraulic support form an integral body when handling roof fall superelevation district, a bridge joint top is bad, can not control the phenomenon of falling the frame well.
Summary of the invention
The technical problems to be solved in the utility model is at present disadvantages of background technology, and a kind of good flame resistance is provided, and anti-pressure ability is strong, and is antistatic, is used for supporting roof processing fast and safely and emits very useful filling bag.
Solve the problems of the technologies described above by the following technical solutions: very useful filling bag is emitted in a kind of processing, comprises solidifying pump, filling jar, filling bag, and the filling jar is connected with the curing pump, solidifies pump and is connected with filling bag.The bag of filling bag is a three layer construction, and its top layer is the flame retardant rubber layer, and nexine is the fire resistance fibre layer of cloth, and internal layer is the flame retardant rubber layer, is filled with foam in the internal layer.
According to technique scheme, compared with prior art, the utility model device is to use the curing pump that the Roc in the filling jar is stopped packing fluid and is filled in the internal layer of bag, adopts this filling bag, comes the roof fall district of supporting different range, make the top of hydraulic support in the roof fall district become as a whole, both saved the supporting expense, and can make wide-ultra high place in roof fall district reduce height gradually again, and made hydraulic support connect the top, prevent down frame, safety waltzs through the roof fall district.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model bag, is the A-A sectional drawing of Fig. 2.
Fig. 2 is filling bag and filling pump, filling jar connection diagram.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
The utility model is to handle down-hole, mine fully-mechanized mining working to emit very useful filling bag, and referring to accompanying drawing 1, its bag is a three layer construction, and top layer 1 is the flame retardant rubber layer, and nexine 2 is fire resistance fibre layer of cloths, and internal layer 3 is flame retardant rubber layers, is filled with foam 4 in the internal layer 3.
Referring to accompanying drawing 2, the tail end of bag 5 is provided with pack hole 7, and the front end of bag 5 is fastening with iron wire 6.During the filling foam, use and solidify pump 9 and filling jar 10,11, filling jar 10, the 11 usefulness filling pipelines 8 of filling packing fluid are connected with curing pump 9 respectively, solidify pump 9 usefulness filling pipelines 8 and are connected with the pack hole 7 of bag 5, and are with No. 8 iron wires 6 that the front end of bag 5 is fastening in case leakage.After filling pipeline 8 was stopped packing fluid suction curing pump 9 with the Roc of filling jar 10,11, the filling pipeline 8 of the filling bag of reinjecting was to bag 5.
During work bag 5 tilt alpha angles are hung on the wire lath that joins at fully-mechanized mining working, gradually Roc is stopped the packing fluid filling with curing pump 9 and advance in the internal layer 3 of bag 5, till whole bag is full of, that pack hole 9 sealings are tight.According to the length of down-hole roof fall, can select and regulate the diameter and the length of bag 5 for use.
The utility model utilizes Roc to stop packing fluid to have high fast expansion rate, good anti-pressure ability, anti-flammability and outstanding characteristics such as antistatic behaviour preferably.The bag 5 of different length, different-diameter is produced in design according to field condition, during use, it is provoked from pursuing frame down with hydraulic support front stretching beam, and supporting roof reaches the effect of controlling roof fall and preventing down frame.
Claims (1)
1, very useful filling bag is emitted in a kind of processing, mainly comprise and solidify pump, filling jar, filling bag, wherein the filling jar is connected with the curing pump, solidify pump and be connected, it is characterized in that the bag of this filling bag is a three layer construction with filling bag, its top layer is the flame retardant rubber layer, nexine is the fire resistance fibre layer of cloth, and internal layer is the flame retardant rubber layer, is filled with foam in the internal layer.
