Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The foldable coal mine emergency rescue device shown in the attached figures 1 to 3 comprises two oppositely arranged beam bodies 1, a chain net 2 is connected between the two beam bodies 1, and the chain net 2 can be folded or unfolded through the relative displacement of the two beam bodies 1. The support frames 3 are respectively arranged below the two beam bodies 1, and the two support frames 3 respectively support the two beam bodies 1. At least two folding arms 4 are arranged on the support frame 3, and when the two folding arms 4 are unfolded, the two folding arms 4 and the two support frames 3 are combined into a frame structure.
The chain net 2 is used for supporting the top of the mine cave, if the two support frames 3 are not combined into a frame structure, when the chain net 2 is stressed, the chain net 2 can generate transverse tension on the beam body 1, and the support frames 3 are toppled; and after two support frames 3 are combined into a frame structure through two folding arms 4, the two support frames 3 form a whole, and transverse tensile force generated on the two beam bodies 1 can be mutually counteracted as internal force, so that the combined frame structure can be kept stable.
The utility model discloses a rescue device is when not using, and folding arm 4 is in fold condition, and two support frames 3 are drawn together, and chain net 2 also draws in, makes the utility model discloses a rescue device's occupation space reduces, convenient transportation and deposits.
The three folding arms 4 are arranged on the support frame 3, when the three folding arms 4 are unfolded, the two folding arms 4 and the two support frames 3 are combined into a frame structure, the other folding arm 4 is connected with the opposite angle of the frame structure, so that two triangles are formed in the frame structure, and the stability of the whole frame structure is improved by utilizing the stability of the triangles.
Folding arm 4 includes hinged end 5 and expansion end 6, the hinged end 5 of folding arm 4 with one support frame 3 is articulated to be connected, makes folding arm 4 can follow the horizontal direction and rotates foldingly, the expansion end 6 and another of folding arm 4 the connection can be dismantled to support frame 3. In one embodiment as shown in fig. 2, a bolt 7 is arranged on the support frame 3, a jack 8 is arranged at the movable end 6 of the folding arm 4, and the movable end 6 of the folding arm 4 is detachably connected with the support frame 3 through the cooperation of the bolt 7 and the jack 8.
Two 3 symmetry settings of support frame, two folding arm 4 is isometric, two when folding arm 4 expandes, two folding arm 4 and two support frame 3 makes up into rectangular frame structure, the length direction of roof beam body 1 is perpendicular with the length direction who constitutes folding arm 4 of frame mechanism, consequently works as when chain net 2 atress, chain net 2 is parallel with folding arm 4's length direction to the horizontal pulling force direction of roof beam body 1, makes whole frame construction's stability better.
The supporting frame 3 is provided with a jacking mechanism 9 for driving the beam body 1 to move upwards, the jacking mechanism 9 is a vertical hydraulic rod, and the beam body 1 and the chain net 2 can be driven to move upwards through the jacking mechanism 9 so as to support the top of the mine tunnel.
