Abstract
The utility model relates to a life-saving appliance of coal mine, particularly to a triangular assembly as a safety life saving channel in a coal footage lane. The utility model is composed of a gou plate (1), a femoral plate (2) and a chord plate (3). The utility model is characterized in that one side of gou plate (1) is provided with a screw (5) and the other side of the gou plate is provided with a supporting pole pipe seat (6) whose bottom surface is provided with a reverse nail (7). The upper side of the femoral plate (2) is provided with a rebar connector (9) and the lower side of the femoral plate is provided with a screw hole (8). One end of the chord plate (3) is provided with a rebar ring (10) and the middle part of the chord plate is provided with a rebar sleeve ring (11) and a supporting pole pipe seat (12). The utility model has the advantages of simple structure, convenient assembly and reusable performance. The femoral plate protects the landslip of one side of coal seam; the chord plate of the upper side of the sidewalk of the footage lane protects the safety of the upper side of pedestrians. Once accidents of landslip and roof collapse happen, the chord plate falls down, and a triangular life saving channel is formed on the other end of the gou plate. The triangular assembly as a safety life saving channel in a coal footage lane fills the blank of the country in the past that after accidents happen, an effective life-saving appliance is not arranged in the distance from the coal footage lane to the plane of working.
Description
Technical field
The utility model relates to a kind of colliery lifesaving appliance, more particularly relates to drilling depth lane, a kind of colliery safe life-saving passage and colludes a strand string assembly.
Background technology
The roof fall accident of the colliery landslide at present overwhelming majority occurs in not to be had in driving lane～drilling depth lane that the cement bedding and clothing cross.This Duan Xiang hole is meant that entering the lane from the master has used the cement bedding and clothing and hole, self-contained lane end to horizontal lane, less hole, lane in the coal seam that exploitation is once again tunneled, or the tunnel, hole, colliery of new exploitation, the hundreds of rice that has forms to several kms exploits in addition cement bedding and clothing of the adit that finishes.The drilling depth lane does not have the lifesaving appliance after the effective accident, in case colliery landslide roof fall, the rescue trapped personnel is very difficult.
The utility model content
The purpose of this utility model provides a kind ofly can have an escape and rescue trunk when the landslide roof fall accident takes place in the colliery, drilling depth lane, the colliery safe life-saving passage of saving trapped personnel colludes a strand string assembly.
The utility model combines by colluding plate 1, strand plate 2, profound plate 3, and be characterized in: a side of colluding plate 1 is provided with screw rod 5, and its opposite side is provided with strut base 6, and its bottom surface is provided with follows closely 7.The top of thigh plate 2 is provided with rebar connector 9, and its below is provided with screw hole 8.One end of boom plate 3 is provided with reinforced steel bar ring 10, and its middle part is provided with the reinforcing bar collar 11 and strut base 12.Rebar connector 9 is made of the reinforcing bar collar 11 of two symmetries.
The utility model has the advantages that simple for structurely, easy to assembly, reusable, when drilling depth lane exploitation then reaches adit, can pull down and be used further in other drilling depth lanes.The thigh plate is the landslide of having protected the one side coal seam again, and the boom plate of top, sidewalk, drilling depth lane has been protected the safety of pedestrian top.In case the landslide roof fall accident takes place, boom plate falls, and is colluding the plate other end, forms one and colludes a strand string escape and rescue trunk.Material is easily purchased easy system, and material is anti-pounds, anti-extrusion, not frangibility.Having filled up China's coal-mine drilling depth lane does not have the blank of lifesaving appliance after effective accident in the past to the scope of operation this segment distance.

The specific embodiment
Be to combine the safe life-saving passage by colluding plate 1, strand plate 2 and boom plate 3 in Fig. 1,2,3,4,5,6,7, the length of wherein colluding plate 1 is 1～1.5m, and wide is 1～2m, and thick is 10～20cm, and concrete size is decided with drilling depth lane size, and material is a reinforced concrete.At pre-buried 4～8 screw rods 5 of a side of colluding plate 1, pre-buried 2 the strut bases 6 of opposite side, the pre-buried two row's side nails 7 in its bottom surface, effect is to be convenient to be buckled on the coal seam.
Thigh plate 2 highly is 2～2.4m, and wide is 1～2m, and thickness is 10～20cm, and concrete size is decided according to the coal hole.The sound insulating panel that its material adopts steel plate bedding and clothing to cross, effect be anti-extrusion, in light weight, be convenient to assembling, can not rupture, cost is lower, and fire-retardant, the anti-power of pounding is strong.The below of thigh plate 2 is provided with 4～8 screw holes 8, will collude screw rod pre-buried on the plate 15 by screw hole 8, will collude plate 1 by nut and be fixed together with a strand plate 2.The top of thigh plate 2 is provided with 3 placing of reinforcement connectors 9, and rebar connector 9 is made up of the reinforcing bar collar 11 of two symmetries, and is connected on strand plate 2 by bolt, is fixed by nut.Strand plate 2 is close to the coal seam wall in drilling depth lane, colliery, makes strand plate 2 and colludes plate 1 and realized the right-angled triangle location.20cm is left in thigh plate 2 upper ends between rebar connector 9, its effect is: can take bar with opposite Dong Bi and be fixed, be close to the thigh plate on the metope simultaneously, stop striding of metope coal seam to be collapsed.
Boom plate 3 is wide to be 1～2m, and thickness is 10～20cm, length for the rebar connector 9 on strand plate 2 to colluding about 105% of plate 1 length, the sound insulating panel that material employing steel plate bedding and clothing are crossed.One end of boom plate 3 is provided with 3 reinforced steel bar rings 10.Be connected on the boom plate 3 by bolt, nut is fixed, and its effect is that reinforced steel bar ring 10 is inserted in the rebar connector 9 of strand plate 2,, is located with nut on boom plate 3 and strand plate 2 polyphones with the reinforcing bar after the wire drawing of two.The middle part of boom plate 3 is provided with the 3 placing of reinforcement collars 11, and effect is to be connected in series mutually with the boom plate of other assemblies.The boom plate other end is provided with strut base 12 at 2/5 place.Strut base 12 and collude grafting strut 4 between the strut base 6 on the plate 1, strut 4 adopts steel pipes, and its effect is: strut 4 outwards has certain radian, guarantees that strut 4 outwards splits out after boom plate 3 is pounded down.Boom plate 3 is fixed on a certain gradient of propping up under the effect of strut 4 at ordinary times, and apart from Horizon 1.25m height, boom plate 3 gradient minimum points should be at 1.4～1.5m as coal car.
The hole, ore deposit is in normal epoch, and the utility model does not influence normal operation, and the pedestrian is open to traffic, and has prevented that also the part coal seam from falling the accident of hurting sb.'s feelings and taking place.In case take place than the landslip roof fall accident, the inclined-plane of boom plate 3 bears immense pressure, and changes angle downwards, with an end closure of colluding plate 1, form one and collude a strand string assembly passage at last.The inclined-plane of boom plate 3 with highly reduced the unexpected impact of acceleration of gravity, the anti-like this ability of pounding is strong, assembly after the closure has only born the extruding force of less than 1/3, and the hole, ore deposit is wide more, pressure is more little, can the back take place at the landslide roof fall accident like this and stay the escape and rescue trunk of the wide 1～1.5m of the next one, and the 60～80cm that can pass through makes dull and stereotyped rescue car by oneself, can in passage, implement to be provided with low pressure seal lamp, phone and oxygen supply pipe etc. for the drilling depth lane.
