The invention discloses rope release equipment having a firefighting rescue function. The rope release equipment comprises a rope winding drum and a rope, wherein the rope is bypassed through the rope winding drum to form a stay rope 1 and a stay rope 2; the stay rope 1 and the stay rope 2 are wound on the rope winding drum in parallel in the same direction; and the rotation of the rope winding drum can be controlled in a position far from the rope release equipment by a segment of distance to drop down the stay rope 1 and the stay rope 2 and to slidingly hung on the rope winding drum.

The invention provides a building with the fire extinguishing and rescuing function. Rope unreeling equipment is arranged above the building and comprises an electric rope reeling device and a cantilever. The electric rope reeling device is arranged on the cantilever and comprises a rope reel, a gear or a chain belt or a transmission belt or a transmission shaft and a motor. The motor is connected with the periphery of the middle portion of the rope reel through the gear or the chain belt or the transmission belt or the transmission shaft and can drive the rope reel to rotate. An inner through hole is formed in the rope reel.

The invention discloses a system with extinguishment and rescue functions, which comprises rope releasing equipment, and a fire-fighting lance or an extinguishment spray gun or a ventilation tuyere or a connecting piece, wherein the rope releasing equipment comprises an electric rope winder and cantilevers; pulleys are arranged on the cantilevers; the electric rope winder comprises rope winding barrels; ropes penetrate through inner holes of the rope winder and extend out of the two ends of the rope winder respectively to form a first pulling rope and a second pulling rope; and the first pulling rope and the second pulling rope extend out of inner holes of the two ends of the rope winding barrels, are wound for a plurality of circles on the rope winding barrels in the same direction, then extend out of the rope winding barrels, round the pulleys on the cantilevers, and then are wound on rope winding trays respectively or wound into coils or folded into bundles.

Provided is building rope pay-off equipment with an extinguishment rescue function. The rope pay-off equipment comprises an electric roper winder, cantilevers and a box. The box is arranged on the cantilevers, and a supporting plate capable of being opened is arranged below the box. Pulleys or rotating discs or rotating shafts or rollers or hanging and pulling supporting pieces are arranged on the cantilevers or the box. The electric roper winder comprises a rope winding drum, a gear or chain belt or transmission belt or transmission shaft and a motor. The motor is connected with the periphery of the middle of the rope winding drum through the gear or chain belt or transmission belt or transmission shaft and can drive the rope winding drum to rotate. An inner through hole is formed inside the rope winding drum. A controller or control switch or control rope can be used outside the pay-off equipment for controlling the rope winding drum to rotate.

A building with fire-fighting and rescue functions. A rope-releasing device is provided at a set position above the building. The rope-releasing device includes an electric rope reel and a cantilever, and a pulley is arranged on the cantilever. The above-mentioned electric rope reel includes a rope reel There is a rope passing through the inner hole of the above-mentioned rope reel and extending from the two ends of the rope reel respectively to form a stay rope 1 and a stay rope 2. Extended from the center and coiled multiple times on the rope drum in the same direction, then extended from the rope drum and bypassed the pulley on the above-mentioned cantilever, and then wound on the rope drum or coiled into rolls or folded into bundles. The lower floor of the building can control the above-mentioned stay rope one and stay rope two to descend downward.

The present invention provides a system with fire fighting and rescue functions. The system comprises a rope releasing device and a fire-fighting lane, or a fire extinguishing spray gun, or a ventilation air opening or a connection piece. The connection piece is provided with the fire-fighting lane, or the fire extinguishing spray gun, or a spray head, or the ventilation air opening. The front side and the rear side of the fire-fighting lane, or the fire extinguishing spray gun or the connection piece are connected with direction changing pulling ropes. The rope releasing device is provided with an electric rope coiling device. The electric rope coiling device comprises warping drums. Ropes penetrate through internal holes in the warping drums and extend out of the two ends of the corresponding warping drums respectively to form first puling ropes and second pulling ropes. The first pulling ropes and the second pulling ropes extend out of the internal holes in the two ends of the corresponding warping drums respectively and are wound on the corresponding warping drums in the same direction. The first pulling ropes and the second pulling ropes can descend downwards, extend and are hung and pulled on the internal holes in the corresponding warping drums.

A building with fire-fighting and rescue functions. An electric rope reel is set above the building. The above-mentioned electric rope reel includes a rope reel. The two ends extend out to form a stay rope 1 and a stay rope 2, and the above stay rope 1 and stay rope 2 respectively extend from the holes at both ends of the rope drum and wind the rope drum in the same direction for multiple turns, and then they are pulled out from the rope drum. Extended from the top and respectively wound on the rope reel or coiled into rolls or folded into bundles, the lower floor of the building can control the above-mentioned pull rope 1 and pull rope 2 to descend downward and extend and hang the inner hole of the pull rope drum superior.
