Abstract
The utility model discloses a novel passing frame provided with a pipeline inside, which is used for a hydraulic rack on a fully mechanized mining working face and is provided with a frame main body with a groove. A steel pipe is arranged in the groove of the frame main body. The utility model solves the problems of bad liquid feed type of the conventional rack, has advantages of simple structure, high safety and easy maintenance and greatly improves the reliability and safety of the hydraulic rack worked on the fully mechanized mining working face.
Description
Technical field
The utility model relates to the passing framework of establishing pipeline in a kind of be used for that coal mine fully-mechanized mining (combine put) working surface hydraulic support uses a kind of novel.
Background technology
At present, the colliery generally adopts the comprehensive mechanization mode to produce.Hydraulic support is to be power with the highly pressurised liquid as the important corollary equipment of comprehensive mechanical coal mining work plane, is made up of hardware and some Hydraulic Elements, can realize supporting, cut the top, move and operation such as pushing and sliding certainly.High-pressure emulsion and spray water that the work plane pumping plant provides for hydraulic support enter each hydraulic support by the total feed flow sebific duct (sebific duct always supplies water) that connects between the support, and the liquid that returns of hydraulic support flows back to pumping plant through total sol pipe that returns.Total feed liquor between hydraulic support (total water supply), total liquid back pipe road use the flexible high pressure rubber hose to be laid between each support.In use connect the high pressure rubber hose poor reliability between the support, fragile.Mainly there is following problem:
1, high pressure rubber hose is directly exposed to the outside, lacks effectively protection, is subjected to the drop impact of spoil, lump coal of top board easily.
2, move for making things convenient for support to draw, high pressure rubber hose all leaves suitable redundancy.But the contact friction of frequent bending and rubber hose shake has caused wearing and tearing.
3, because what flow in the rubber hose is highly pressurised liquid, have certain danger, in changing the hydralic hose process, operation has slightly improperly will cause personal injury.
4, high pressure rubber hose poor reliability, fragile, often needing stops production changes hydralic hose, is seriously restricting the ordinary production of comprehensive mechanical coal mining work plane.
5, because in recent years, the development of electric hydraulic control technology, the neighboring frame-operated of support can be by automatically controlled realization, and the pipeline that connects between the hydraulic support mainly is total feed flow, always returns liquid and total water supply sebific duct.
Like this, between frame, arrange high pressure rubber hose poor reliability, fragile, just become a problem that presses for very much solution.
The utility model content
The purpose of this utility model provides a kind of passing framework, and is simple in structure, safe, be easy to safeguard.
For achieving the above object, technical scheme provided by the utility model is: a kind of passing framework, comprise the chassis body that has groove, and be provided with steel pipe in the groove of described chassis body.
Described steel pipe is provided with 2～5, and is arranged side by side.
The two ends of described chassis body are respectively equipped with connector and hinging pin shaft.
The advantage that the utlity model has:
1, make total feed flow of hydraulic support, always return liquid, always supply water sebific duct and branch line is effectively protected.Improve the safety and the reliability of feed flow, water supply.
2, effectively reduce of the influence of comprehensive mechanical coal mining working surface hydraulic support fault, guarantee the ordinary production of work plane working surface production.
3, effectively reduce the maintenance workload of work plane, reduce working strength of workers.
4, effectively reduce the security incident of breaking and causing, help the safety in production of mine because of fluid pressure line.
In sum, the utility model has overcome the deficiency of original support feed liquid way, its have simple in structure, safe, be easy to characteristics such as maintenance, increased substantially the reliability and the safety of the work of comprehensive mechanical coal mining working surface hydraulic support.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but content of the present utility model be not limited to for embodiment.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the longitudinal sectional view of Fig. 1;
Establish pipeline in Fig. 3 uses and pass the hydraulic support schematic diagram of framework feed flow.
Among the figure: 1 ... chassis body 2 ... steel pipe 3 ... connector 4 ... hinging pin shaft
5 ... draw and move jack 6 ... sebific duct 7 ... branch's sebific duct 8 ... operation valve group
9 ... hydraulic support 10 ... anterior transporter 11 ... cable channel 12 ... sebific duct in the groove
The specific embodiment:
A kind of passing framework as illustrated in fig. 1 and 2 comprises the chassis body 1 that has groove, is provided with steel pipe 2 in the groove of described chassis body 1, and steel pipe 2 is provided with 2～5, and is arranged side by side.Be respectively equipped with connector 3 and hinging pin shaft 4 at the two ends of chassis body 1.
As shown in Figure 3, lay steel pipe 2 in the passing chassis body 1 of hydraulic support 9, the quantity of steel pipe 2 is determined according to the actual needs of feed flow, water supply, generally between 2～5.With total feed flow of hydraulic support main body 1, always return that sebific duct 12 is arranged in the cable channel 11 of work plane front portion transporter 10 in the grooves such as liquid and total waters supply.Sebific duct 12 is connected with steel pipe 2 by branch's sebific duct 7 in the groove, and steel pipe 2 is connected with the operation valve group 8 of hydraulic support main body 1 by sebific duct 6 again.
Passing chassis body 1 is moved jack 5 by hinging pin shaft 4 and drawing of hydraulic support 9 and is connected, and is connected with anterior transporter 10 by connector 3.In hydraulic support 9 courses of work, by drawing the flexible realization that moves jack 5 to pass anterior transporter 10 and drawing moving hydraulic support main body 1.Pass chassis body 1 and move in jack 5 motion processes with drawing, sebific duct 6 is with passing the motion of framework warpage.
The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Any those skilled in the art, all still belong in the protection domain of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
Claims (3)
