Abstract
The utility model discloses a super-soft ultra-thick coal seam large section open-off cut support device, and relates to a mine tunnel support device. The problems that a conventional support mode of a mine tunnel at pressure cannot meet the requirements on the use and security of the tunnel, and the like, are solved. According to the super-soft ultra-thick coal seam large section open-off cut support device, U-shaped steels at a heading tunneling side and U-shaped steels at a slipping side are connected in a lap joint mode and are fixed into shed beams by two pairs of fixing cables in the length of 40cm; the distance between the shed beams is 40-50cm; and the shed beams are fixedly connected together by positioning clamping cables through bolts and pulling plates. The super-soft ultra-thick coal seam large section open-off cut support device is simple in structure and convenient to install, the materials are saved, the tunnel deformation is controlled, and the security use of a mine tunnel is ensured.
Description
Technical field
The utility model relates to a kind of mine roadway support device, particularly relates to the large Cross-section Cut suspension device of a kind of dead-soft super high seam.
Background technology
Present colliery applying along with the high-yield and high-efficiency comprehensive coal face, the large ratio of Cross Section Coal Roadway in coal mine roadway improves gradually, the open-off cut span of the fully mechanized coal face of large Cross Section Coal Roadway is large, is again the place that coal excavation apparatus is installed, and therefore the safety of large Cross Section Coal Roadway is had higher requirement.Particularly in soft super high seam, it generally is to adopt common anchor net beam rope combined supporting with the bottom application worker that comprehensive coal face is cut eye, main support material is i iron and hydraulic prop, and therefore i iron lap-joint stressed just on certain point rather than born by face very easily cause with Louing push up; The supporting of each i iron is the self supporting, affected by roof weighting, easily causes the i iron discontinuity and causes i iron bending, distortion, changing of the relative positions displacement; Partial monosomy hydraulic prop column cap and i iron become point to contact and cause the bad stability of supporting, and support effect is undesirable; Owing to use i iron all to need to adopt a beam four post supportings as capplce, this needs to increase the quantity of hydraulic prop and the waste that causes material to a certain extent; Because to cut a span large, crush obviously again, existing support pattern can't satisfy use and the safety requirements in tunnel.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of simple in structure, easy for installation, economical with materials, the distortion of control coal road is provided and can ensures the large Cross-section Cut suspension device of dead-soft super high seam of safety of coal tunnel.
For achieving the above object, the utility model provides the large Cross-section Cut suspension device of a kind of dead-soft super high seam to comprise and leads the U-shaped steel of cave side, the U-shaped steel of the large side of brush, fixed card cable, positioning clamp cable and arm-tie, leads the U-shaped steel of cave side and fixedly forms capplce with 40 centimetres length overlap joint and in lap-joint by two secondary fixed card cables with the U-shaped steel of the large side of brush; Distance between described capplce and the capplce is 40 centimetres to 50 centimetres, is fixedly connected with arm-tie by bolt by positioning clamp cable between capplce and the capplce.
The described length of leading the U-shaped steel of cave side is 350 centimetres, and the length of brushing the U-shaped steel of large side is 400 centimetres, and the distance between described capplce and the capplce is 40 centimetres.
The utility model beneficial effect is: the large Cross-section Cut suspension device of dead-soft super high seam of the present utility model is simple in structure, easy for installation; Two U-shaped steel overlapping modes of every canopy can save a hydraulic prop, have saved support material, have also saved certain space for the tunnel simultaneously; Adopt U-shaped steel overlap joint and be connected into integral body and controlled the deflection in tunnel by card cable and arm-tie, for the safe handling in tunnel provides guarantee.
Below in conjunction with accompanying drawing the large Cross-section Cut suspension device of dead-soft super high seam of the present utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model uses the status architecture schematic diagram in cutting a section.
Among the figure: 1, lead the U-shaped steel of cave side, 2, brush large side U-shaped steel, 3, the fixed card cable, 4, positioning clamp cable, 5, arm-tie, 6, capplce, 7, hydraulic prop, 8, track, 9, round log.
The specific embodiment
As shown in Figure 1, the large Cross-section Cut suspension device of the dead-soft super high seam of present embodiment comprises leads the U-shaped steel 1 of cave side, the U-shaped steel 2 of the large side of brush, fixed card cable 3, positioning clamp cable 4 and arm-tie 5, leads the U-shaped steel 1 of cave side and fixedly forms capplce 6 with 40 centimetres length overlap joint and in lap-joint by two secondary fixed card cables 3 with the U-shaped steel 2 of the large side of brush.Distance between capplce 6 and the capplce is 40 centimetres, is fixedly connected with arm-tie 5 by bolt by positioning clamp cable 4 between capplce 6 and the capplce.The length of leading the U-shaped steel 1 of cave side is 350 centimetres, and the length of brushing the U-shaped steel 2 of large side is 400 centimetres.Because U-shaped steel is higher than i iron intensity, compression capability is strong; I iron can not form contact surface after also having overlap joint, and stressed place is only on point, and U-shaped steel can two overlaps, and is plane-plane contact, available card cable chucking and form an integral body.
As shown in Figure 2, every capplce 6 times is supported by seven hydraulic props 7, wherein the hydraulic prop 7 in the middle of track 8 is props, the column cap of hydraulic prop 7 and lead the U-shaped steel 1 of cave side or brush between the U-shaped steel 2 of large side with the timber wedge pad to strengthen the stability of supporting, prevent from leading the U-shaped steel 1 of cave side or brush U-shaped steel 2 rollovers of large side, cut eye two and help to be supported by round log 9.Because the overlap joint between U-shaped steel is plane-plane contact, can save a hydraulic prop 7 so compare with the overlapping mode of i iron, and about 350 of the use amount that whole large Cross-section Cut can reduce hydraulic prop 7 has greatly been saved support material, has reduced cost.
