Description
Technical field
The utility model relates to a kind of tunnel i-beam frame, belongs to roadway engineering field.
Background technology
I-beam frame supporting is as support pattern the most frequently used in coal mine roadway, in coal mine roadway application very extensive, all application to some extent in most of coal mine roadways at home.I-beam frame is general adopts simple chain and U-shaped i-beam frame is carried out chain, but because this kind of linkage structure connects too simple, stability is bad, can not play the effect of active adjustment rate of tension, and also easily there is in some cases security incident, for example: when tunnel side pressure is excessive, easily cause rack beams rollover, fracture, the problem such as crooked, then easily cause the support phenomenon that collapses; For another example: when punching press occurs top, tunnel, tunnel i-beam frame can be due to the unstable cave in accident that occurs.
Summary of the invention
The purpose of this utility model is to provide the tunnel i-beam frame that a kind of safety stability is high, rate of tension is adjustable, thereby solves involved technical problem in background technology.
A tunnel i-beam frame, is comprised of arc i iron, i iron compression layer, pressure detector, display instrument, level gauge, searchlight, upper bracket leg, lower carriage leg, hydraulically extensible leg, hydraulic handle and trapezoid support pin; It is characterized in that described arc i iron is arc arch shape solid steel plate, its upper strata is i iron compression layer, i iron compression layer inside is a lot of spring connecting structures, the central interior of i iron compression layer is provided with the pressure detector of i-beam frame, and pressure detector transfers data to above the display instrument being installed on the body of wall of tunnel by wire; Described level gauge is positioned at the middle part of arc i iron, the parallel installation of lower limb of level gauge and arc i iron; The two sides of described arc i iron are all provided with the searchlight of two outside searchlightings; The upper end of described upper bracket leg is connected by bolt with the two side ends of arc i iron, and lower end is connected with hydraulically extensible leg; The lower end of described hydraulically extensible leg is built in the inside of lower carriage leg; The inside of described lower carriage leg has hydraulically extensible cavity configuration, and outside has hydraulic handle structure, and lower end is connected with trapezoid support pin.
The utlity model has following advantage is: the first structure easily dismantles, convenient and practical; Second has improved resistance to overturning and the safety of steelframe; The 3rd has realized the demonstration directly perceived of poppet pressure, and can to the pressure of steelframe, suitably adjust by hydraulic system.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: arc i iron 1, i iron compression layer 2, pressure detector 3, display instrument 4, level gauge 5, searchlight 6, upper bracket leg 7, lower carriage leg 8, hydraulically extensible leg 9, hydraulic handle 10, trapezoid support pin 11.
The specific embodiment
Be below the better embodiment of the utility model patent, therefore do not limit protection domain of the present utility model.
As shown in Figure 1, a tunnel i-beam frame, is comprised of arc i iron 1, i iron compression layer 2, pressure detector 3, display instrument 4, level gauge 5, searchlight 6, upper bracket leg 7, lower carriage leg 8, hydraulically extensible leg 9, hydraulic handle 10 and trapezoid support pin 11; It is characterized in that described arc i iron 1 is arc arch shape solid steel plate, its upper strata is i iron compression layer 2, i iron compression layer 2 inside are a lot of spring connecting structures, the central interior of i iron compression layer 2 is provided with the pressure detector 3 of i-beam frame, and pressure detector 3 transfers data to above the display instrument 4 being installed on the body of wall of tunnel by wire; Described level gauge 5 is positioned at the middle part of arc i iron 1, the parallel installation of lower limb of level gauge 5 and arc i iron 1; The two sides of described arc i iron 1 are all provided with the searchlight 6 of two outside searchlightings; The upper end of described upper bracket leg 7 is connected by bolt with the two side ends of arc i iron 1, and lower end is connected with hydraulically extensible leg 9; The lower end of described hydraulically extensible leg 9 is built in the inside of lower carriage leg 8; The inside of described lower carriage leg 8 has hydraulically extensible cavity configuration, and outside has hydraulic handle 10 structures, and lower end is connected with trapezoid support pin 11.
The utlity model has following advantage is: the first structure easily dismantles, convenient and practical; Second has improved resistance to overturning and the safety of steelframe; The 3rd has realized the demonstration directly perceived of poppet pressure, and can to the pressure of steelframe, suitably adjust by hydraulic system.Solved the problem of mentioning in background technology, novel structure and easily operation, have larger value for applications.
