Description

Technical Field

[0001] The utility model relates to the technical field of risk avoidance and escape devices, in particular to an underground escape guiding device. Background Art

[0002] At present, the emergency shelters in mines mainly rely on refuge chambers and lifeboats. Due to the large size of the lifeboat itself, it is impossible to set the lifeboat too close to the working face, and the chamber is relatively far away from the refugees. Therefore, an escape guidance device is needed to guide from the working face to the emergency shelter.

[0003] The commonly used escape guidance device is to set up disaster escape route signs at different locations underground. The signs are made of lightweight foam with reflective materials and can only be identified under the illumination of visible light and lights. However, once an accident occurs underground, the above signs may be damaged by the shock wave of the explosion or the impact of coal, rock, falling rocks, etc. or fire. The underground lighting may also be damaged. When the miner's headlight is damaged or the battery is exhausted, there is no visible light in the underground tunnel, and the correct disaster escape route cannot be identified, which creates obstacles for personnel to rescue themselves.

The screw-on round block 22 at the end is connected to the outside of a fixed seat 11; the guide rope 21 is a high-temperature resistant and fire-retardant wire, and the outer wall of the guide rope 21 is sprayed with fluorescent powder doped with divalent manganese metal complex powder; the guiding component 5 is fixed on the bearing plate 4, and the guiding component 5 includes a supporting block and an identification block. The supporting component is fixed to the bottom end of the guiding bracket to adapt to the uneven lanes. The guiding brackets are adjacent to each other, and the screw-on round block of the guide rope on the outside of one guiding bracket is threadedly connected to the fixed seat on the outside of another guiding bracket. Several guiding brackets are connected in series and distributed on both sides of the lane to guide the direction.

[0027] like Figure 3 and Figure 4 As shown, the friction assembly 3 includes a plurality of friction rings 31, a fixed plate 32, a sliding chamber 33 and an annular glass 34. The plurality of friction rings 31 are slidably arranged on the outer wall of the guide rope 21, the fixed plates 32 are annularly distributed on the outer wall of the friction ring 31, the sliding chamber 33 is arranged on the outer side of the fixed plate 32, and the annular glass 34 is installed on the outer side of the sliding chamber 33.

[0028] like Figure 1 As shown, the guide bracket 1 includes four legs 12 and two top plates 13, two legs 12 are fixed at the bottom of each top plate 13, the two top plates 13 are hinged, each leg 12 includes a support rod and a movable rod, the support rod is fixed on the top plate, the movable rod is slidably arranged inside the support rod, a plurality of screw holes are opened inside the support rod and the movable rod, bolts are screwed inside the screw holes to connect the support rod and the movable rod; two fixing seats 11 are fixed on one top plate 13. The guide bracket 1 can be folded through the two top plates.

[0029] like Figure 5 As shown, the support assembly 6 includes: an articulated seat 61, a fixed block 62, a first short rod 63, a second short rod 64 and a support block 65. The articulated seat 61 is connected to the bottom end of the movable rod, the fixed block 62 is rotatably matched with the articulated seat 61, and four square holes of the same size are opened inside the fixed block 62. The first short rod 63 is slidably set inside the two square holes on both sides of the fixed block among the four square holes, and the second short rod 64 is slidably set inside the two square holes in the middle of the fixed block, and the outer ends of the first short rod and the second short rod are both provided with support blocks 65.

[0030] like Figure 6 As shown, the pattern of the identification block includes a disaster evacuation route identification 51, a refuge chamber identification 52, a safety exit identification 53, a return air direction identification 54, an inlet air direction identification 55 and a no-entry identification 56.

[0031] The length of the guide rope between the two fixing seats is 1 meter, and the length of the guide rope outside the fixing seats is 5 to 10 meters, which is convenient for connection.

[0032] The guide brackets are connected to each other and are set on both sides of the mine passage to guide the underground workers out of trouble. The two fixed seats on the top of the guide bracket, the rotating round blocks at both ends of a guide rope are respectively screwed to the inside of the two fixed seats, and the rotating round block at one end of the other guide rope is connected to the outside of a fixed seat, and the rotating round block at the other end of the guide rope is connected to the fixed seat on the outside of the adjacent guide bracket that is not connected to the guide rope, so as to realize the series connection of two adjacent guide brackets. The guide rope is a high temperature resistant and fire retardant wire, which is easy to install. It can still remain connected in the event of a fire or other accidents in the mine to guide the workers.

[0033] The bottom end of the movable rod is fixed with a support assembly, which is used to adjust the height of the guide bracket. Since the ground of the mine is uneven, it needs to be adjusted through the support assembly and four legs. According to the actual placement of the ground, unfold the two top plates of the guide bracket, fix the support rods and the movable rod on the four legs, and pull out the first short rod and the second short rod from the fixed block of the support assembly to increase the contact area between the bottom of the support assembly and the ground. The support assembly has a simple structure and is easy to operate. It can be stored as the guide bracket is folded, saving space and facilitating transportation.

[0034] The friction component is slidably arranged on the outside of the guide rope, and the guide rope is sprayed with fluorescent powder doped with divalent manganese metal complex powder. When a force is applied to the friction component, the friction component contacts and rubs with the guide rope, and the brightness of the fluorescent powder doped with divalent manganese metal complex powder is stimulated, and a weak light is emitted, thereby providing guidance. An annular glass is installed on the outside of the sliding compartment of the friction component. When the staff members hold the annular glass in their hands and slide and rub on the guide rope in a dark environment, the stimulated light will be emitted, either directly or from the gaps between several friction rings through the annular glass. In addition, the green light emitted by the fluorescent powder doped with divalent manganese metal complex powder under the action of external force will not dissipate immediately, but will last for a short time, illuminating the position of the guide rope, providing guidance direction, and can be used continuously.

[0035] The guidance component provides identification information for underground workers and guides them. By making the identification blocks of different styles with different identification shapes, they are fixed on the outer wall of the card block, and the outer side of the identification block is affixed with a reflective film. When the workers in the mine walk to the side of the identification block through the guide rope, they can identify the identification block information through the weak light and the reflective film, or identify the type of identification block by touching the shape of the identification block, thereby understanding the location information of the facilities in the mine.
