Abstract
The invention relates to an automatic mine filling pipeline switching device. The automatic mine filling pipeline switching device comprises a bracket, a connecting pipe, a swing pipe oil cylinder and a pressing oil cylinder, wherein a feed port is formed at one end of the bracket; a plurality of discharge ports are formed at the other end of the bracket; the inlet end of the connecting pipe is fixedly connected and communicated with the feed port; the outlet end of the connecting pipe is connected with the swing pipe oil cylinder and is selectively communicated with one of the plurality of discharge ports under the action of the swing pipe oil cylinder; the pressing oil cylinder is provided with a telescopic piston rod; and when the piston rod stretches out, the outlet end of the connecting pipe can be pressed on the discharge port communicated with the outlet end.
Description
Technical field
The present invention relates to a kind of mine shaft filling pipeline, relate in particular to a kind of automatic switching device of mine shaft filling pipeline.
Background technology
Mine filling is a kind of common processing method of present stage to mine goaf.Common mine filling arranges standpipe peace pipe connecting downhole goaf, carries attal by standpipe peace pipe from ground to underground goaf, makes underground goaf obtain certain structural strength, to avoid avalanche, ground to fall into the generation of the geology harm such as sky.
When mine filling, attal ratio of viscosities is larger conventionally, and roughness ratio is higher, and pipeline jam accident often occurs in filling pipeline.Being subject to the restriction of filling pipe line structure, seldom there is the phenomenon of plugging in standpipe, and plugging often occurs in the flat pipe in shaft bottom.Once generation pipeline jam accident, will affect whole filling process, sometimes even all dredge several days badly, have a strong impact on pack effectiveness.Therefore, generally at least need two circuits in down-hole, in the time of a circuits generation pipeline jam accident, be switched to immediately another set of pipeline.In existing engineering application, when switching, mostly adopt manual switching, waste time and energy, reliability is not high, cannot meet the needs of this area filling.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of automatic switching device of mine shaft filling pipeline, comprises support, tube connector, swing pipe oil cylinder and compressed oil cylinder;
One end of described support is provided with charging aperture, and the other end is provided with multiple discharging openings;
The arrival end of described tube connector is fixedly connected with described charging aperture and is coupled logical, and the port of export of described tube connector is connected with swing pipe oil cylinder, and in selectable and multiple discharging openings is connected under the effect of swing pipe oil cylinder;
Described compressed oil cylinder has telescopic piston rod, in the time that piston rod stretches out, the port of export of described tube connector can be pressed on the discharging opening being communicated with the port of export.
Described multiple discharging opening is two discharging openings.
Described charging aperture and described discharging opening comprise flange, and the two ends of described tube connector are respectively arranged with flange, and described tube connector is connected by flange with described charging aperture and described discharging opening.
Described swing pipe oil cylinder and described compressed oil cylinder all arrange internal stent.
Described tube connector is flexible pipe.
The operating pressure of described compressed oil cylinder is greater than 20Mpa.
Also comprise auxiliary clamping device, described auxiliary clamping device comprises set bolt.
The invention has the advantages that: simple in structure, installation and maintenance are convenient, failure rate is low; Hydraulic-driven, switches reliable rapidly; Carry two kinds of hold down gags, prevent the leakage of casting resin.
Brief description of the drawings
The elevation of the preferred embodiment that accompanying drawing 1 is automatic switching device of mine shaft filling pipeline of the present invention;
Accompanying drawing 2 is that the B-B of automatic switching device of mine shaft filling pipeline in accompanying drawing 1 is to sectional view.
Reference numeral is as follows:
1-support; 2-tube connector; 3-oscillating oil cylinder; 4-compressed oil cylinder; 5-charging aperture; 6-discharging opening; 7-auxiliary clamping device.
Detailed description of the invention
Referring to accompanying drawing 1-2, it has been described according to automatic switching device of mine shaft filling pipeline of the present invention preferred embodiment.Automatic switching device of mine shaft filling pipeline comprises support, tube connector, swing pipe oil cylinder and compressed oil cylinder, support is the metal framework of the basic one-tenth cuboid that is connected into of angle steel, steel pipe or other steel welding, and tube connector, swing pipe oil cylinder and compressed oil cylinder are all arranged on internal stent, and one end of support is provided with a charging aperture, and the other end is provided with two discharging openings, the arrival end of tube connector is fixedly connected with charging aperture and is connected with charging aperture, the port of export of tube connector is connected with swing pipe oil cylinder, the flexible of the piston rod of swing pipe oil cylinder can move freely the port of export of tube connector by mechanical device in certain scope, thereby selectable any one with two discharging openings is connected, tight with being connected of discharging opening for ensureing the port of export of tube connector, prevent casting resin leakage, after tube connector is communicated with discharging opening, need to use connecting of compressed oil cylinder sealed joint pipe and discharging opening, compressed oil cylinder has telescopic piston rod, its operating pressure is greater than 20Mpa, when in the time that operating pressure lower piston rod stretches out, just the port of export of tube connector is pressed on the discharging opening being communicated with the port of export, realize the sealed attachment of tube connector and discharging opening, simultaneously, consider that compressed oil cylinder insufficient pressure likely occurs in down-hole or hydraulic workstation does not have the situations such as feed flow, automatic switching device of mine shaft filling pipeline can also arrange auxiliary clamping device, comprise set bolt, the be tightened method of bolt of use is further pressed on the port of export of tube connector on discharging opening.
Charging aperture and discharging opening can be flange plate structures, and the flange that its two ends in tube connector arrange is corresponding, form flange and connect.
For convenience of the movement of tube connector, can use flexible pipe, as rubber tube, steel-plastics composite pipe etc., also can adopt movable jointing method is set in tube connector, as long as it meets filling requirement.
The above; it is only preferably detailed description of the invention of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with in technical scope that those skilled in the art disclose in patent of the present invention; the variation that can expect easily or replacement, within all should being encompassed in the protection domain of patent of the present invention.
